Service HotlineIn the riveting connection of various structural parts, waterproof lantern rivets have been widely used in riveting environments that require waterproofing. After the riveting parts are riveted, the waterproof structure area of the mandrel and the waterproof structure of the rivet body There is no complete close fit between the areas. In some riveting ranges, the waterproof performance of the rivet is affected. The main reason is that the traditional processing technology of the mandrel and the materials used bring many troubles to the riveting process. is a problem to be solved at present.
pin fixing device, comprising fastening bolts for processing and fixing two workpieces, wherein the pin fixing device further comprises a fixing groove arranged on the workpiece, a positioning hole which is arranged on the workpiece and communicated with the fixing groove, and a positioning hole is arranged in the positioning hole A pin is provided with a pin bushing, the pin bushing is sleeved on the positioning pin, an accommodation space is provided between the pin bushing and the inner wall of the fixing groove, and colloid is filled in the accommodation space. The use of the pin fixing device of Guangdong Yueluo Hardware Industry Co., Ltd. can greatly improve the positioning accuracy of the pin, improve the processing efficiency, reduce the manufacturing cost, testing cost and labor cost, with strong mobility and quick response.
Beneficial effects The commonly used nuts and bolts in the prior art are in the shape of a hexagon, the fastening surface is a regular hexagonal plane, and there are six elastic surfaces, and the adjacent elastic surfaces intersect with a straight line, and the opposite elastic surfaces are parallel to each other, In this way, the tightening operation can be easily performed with conventional tools, which is convenient and practical. However, there are some special occasions where the nuts and bolts of this structure are not suitable. Guangdong Yueluo Hardware Industry Co., Ltd. changed the fastening surface into a pentagon shape, and the adjacent elastic surfaces are connected by an arc angle. sex.
The nuts in the prior art are easy to fall off during work, especially in harsh environments or environments with large vibrations. Sometimes it is necessary to add parts such as gaskets to prevent them from falling off, but they are still easy to fall off and cause harm.
A screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. A drill-tail screw is a screw with a self-tapping drill head on the front end of the screw. The screw is a common invention in people's production and life for thousands of years. According to the application field, it is the first invention of mankind. Drilling screw is a new invention in recent years, also called self-drilling screw. A screw is a common term for fasteners, an everyday colloquial language.
