Service HotlineR-type plastic rivets, also known as expansion rivets, are composed of plastic sub-nails and female buckles. It is not necessary to use installation tools during installation, place the installation base in the smooth hole, and then press the head, the specially designed feet expand and stretch after being stressed, and are firmly locked on the installation surface. It is often used to connect plastic shells, lightweight boards, insulating materials, circuit boards, or any other thin, light-weight materials. It is beautiful, practical, and easy to use.

Axle card is a kind of hole-to-hole movement installed on a slotted shaft and used as a fixed component. The inner diameter of this type of retaining ring is slightly smaller than the diameter of the assembly shaft. Application No. 201621153710.9 discloses a shaft card assembly device, including a feeding mechanism, a material distribution mechanism, a material reclaiming mechanism and an assembling mechanism. The feeding mechanism is connected with the feeding mechanism. The reclaiming mechanism includes a reclaiming tool and a servo system for driving the movement of the reclaiming tool. One end of the reclaiming tool is provided with a c-shaped opening, and an incision connected with the c-shaped opening is provided. The assembling mechanism includes a carrier for fixing the parts to be loaded and a turntable, and the carrier is mounted on the turntable. In the above shaft card assembly device, after the feeding mechanism completes the feeding, the material distribution mechanism separates the shaft card to a specific position with a fixed attitude, and then the private server drives the reclaiming tool to clamp the shaft card and assemble it to the pre-fixed by the assembly mechanism. on the fitting. During the assembly process, the manual workload is small, the efficiency is high, and the labor intensity is small. At the same time, the c-shaped opening and the cutout at the end of the reclaiming tool are designed to effectively form an elastic force to clamp the clamping shaft card and absorb the assembly process. The resulting outward deformation force avoids the plastic deformation of the shaft card due to the large external force.
T-bolt is a common fastener, which is mostly used where there is a T-slot on the workbench or where the connection can only be made from the side to be connected. However, it has the following problems in the actual production and processing process. 1. The T-bolt manufactured according to the current GB37-88 is used in conjunction with the T-slot on the worktable, which is easy to damage the T-slot on the worktable. 2. According to the observation and investigation, it is found that 90% of the damage to the T-bolt manufactured by GB37-88 is thread damage during use, and the T-shaped part is rarely damaged, resulting in a waste of raw materials. SUMMARY OF THE INVENTION The purpose of the present invention is to solve the problem that the current composite T-bolt is easy to damage other equipment and cause waste of raw materials in the actual use process, and to provide a simple structure, easy to use, safe and reliable, and not easy to damage other equipment. , thereby saving raw materials and other advantages of composite T-bolts. In order to achieve the above purpose, the present invention adopts the following technical scheme: a composite T-bolt, which includes a bolt, and one end of the bolt is connected with the T-shaped block cockroach. The T-shaped block is provided with a tapered hole, and the connection between the bolt and the T-shaped block is a cone, which is matched with the tapered hole. The utility model combines the two parts of the T-shaped block and the threaded bolt through the T-shaped block and the taper hole and the cone on the bolt to automatically lock the two parts before use. When the threaded part of the bolt is damaged, only the threaded bolt needs to be replaced. That's it. Compared with the domestic T-shaped bolts currently produced in the manufacturing process, the utility model solves the problems of complicated manufacturing processes and waste of raw materials. It is well known that the manufacture of T-bolts requires processing such as forging, turning, milling, and heat treatment. Since the composite T-bolt is used in combination with the T-block and the bolt, and the T-block is rarely damaged, after purchasing or manufacturing the T-block once, you only need to purchase or manufacture the bolt in the future. Compared with the T-bolts currently produced in China, the composite T-bolts can better protect the T-slots on the working surface. Because the T-bolt currently produced in China will rotate a certain angle around the axis of the T-bolt when fixing the object, the T-bolt will rotate at a certain angle, thereby reducing the contact between the T-bolt T-shaped surface and the T-slot stress surface of the working face. surface, causing stress concentration on this surface. The composite T-bolt avoids the above problems due to the increase of the guide surface, thereby protecting the T-slot. The beneficial effects of the utility model are: 1. Saving raw materials. 2. Reduce processing costs. 3. Simplify the technological process. 4. Protect the T-slot.
As we all know, whether it is the necessities in people's life or the equipment in industrial production, there will be a structure of screws and screw holes on it. This kind of structure that can simply fix some components together has been widely used in various fields. For the installation and removal of screws, people invented manual screwdrivers, and then to electric screwdrivers and so on. For manual screwdrivers, the operator needs to manually install or remove the screws. When encountering small screws, it can still handle it. When encountering large screws, due to people's limited strength, they may not install the screws in place, so it was invented. Electric screw. When installing the screw, which is widely used in the market, the operator needs to hold the screw handle, fix the screw on the screw port, and then align the screw with the corresponding screw hole for screwing. The disadvantage of this kind of screw is that it is heavy in quality and laborious to operate, and secondly, the operator will be injured due to operating errors, and the consequences are extremely serious. In view of this deficiency, people fix the screws on a work frame, so that before installing the screws, the operator only needs to adjust the screws to the designated position, and then the screws can be installed, which is convenient and simple. However, there are still potential safety hazards. In the process of adjusting the screw, it is still possible that the power of the screw may be turned on by mistake due to operating errors, resulting in injury to the operator. In view of the above-mentioned defects, it is necessary to invent a screw installation method with an anti-missing function.
