Service HotlineThe tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination, so it is safe to use. Especially in the combination of construction, construction, residential and other places, self-tapping and self-drilling screws are the best economical fasteners in terms of workability, cost and reliability. Now the construction of high-rise buildings and high-speed traffic in mainland China requires more high-quality drill screws;
As one of the screws, self-tapping screws can directly drill holes on the plate to be fixed by themselves and lock them together with the plate to be fixed. They are easy to use and have a good fixing effect, so they are widely used. However, in the prior art, when the screw is perforated on the plate to be fixed, it is prone to skew, which affects the fixing effect and also reduces the aesthetics. To sum up, how to overcome the above-mentioned defects of the screw fixing method in the prior art is a technical problem to be solved urgently by those skilled in the art.
The surfaces of the existing door panels are spliced together by fasteners such as nails and bolts. For example, a door body structure for a production line disclosed in CN203807555 is used for the doors of each chamber of the coating production line. The size of the mechanism is the same, and the left and right sides of the door body can be freely opened and closed; the chamber door and the door frame are detachably connected by multiple sets of sealing components, and the sealing components include hinge devices and locking parts.
In view of the deficiencies in the prior art, the purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a detachable rivet to solve the problems raised in the above-mentioned background technology. Guangdong Yueluo Hardware Industry Co., Ltd. is easy to use, easy to operate, and has good stability. , high reliability.
Bolts are widely used in the machinery industry. Round head bolts are generally fixed in equipment parts, but during long-term use, due to external force or vibration of the equipment itself, the bolts are loosened, and the bolt heads have a long-term use process. A fatal disadvantage is that it is prone to slippage, which can cause major safety hazards and economic losses to users in severe cases.
