Summary of information:We have more than ten years of production experience in the screw industry. The main products are: plug screws, DIN186 b...

AucklandAucklandhand screw is a screw with a plastic head, and the user fixes the AucklandAucklandhand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of ordinary screws, and the height is 9cm. The screw of the AucklandAucklandhand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the AucklandAucklandhand screw.

Referring to Figure 1, one end of the existing insert nut 1' is embedded in the injection molded part 2', and the other end is exposed to the injection molded part 2'. The insert nut 1' has opposite lower and upper end surfaces in the axial direction. The end face of one end of the insert injection molded part 2' is the lower end face. In order to reduce the resistance during hot pressing, the connection between the inner wall surface and the lower end surface of the insert nut 1 ′ is provided with an inclined surface. However, when the embedded nut 1' of this structure is hot-pressed, the hot melted glue will generate a shunt that rises along the slope, and then a convex peak is formed in the screw hole of the embedded nut 1', and the convex peak occupies the screw. The space in the hole prevents the screw 5' from being completely screwed in; at the same time, due to the shunting of the hot solder, the knurling of the inner nut 1' near the upper end face cannot be filled with the solder, which makes the inner nut 1' and the inner nut 1' and The injection part 2' is not firmly embedded. Therefore, the locking strength of the existing insert nut 1 ′ and the screw 5 ′ after being hot-pressed is relatively low.

A medical self-locking screw, wherein the medical self-locking screw is composed of an outer screw and an inner screw, the outer screw includes a fixedly connected fitting body and the front part of the outer screw, and the front part of the outer screw includes a fixed connection The outer screw rod body and the outer screw head are provided with fixed external threads on the periphery of the outer screw rod body, and a Aucklandbackstop ring is provided on the periphery of the matching body;

In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.

Existing bolt and nut connections usually use threads for connection, and this connection method has two main drawbacks. First, tools are required to be used to lock it during installation, and it takes a long time to complete, which is time-consuming and labor-intensive; Second, the installed bolts and nuts are prone to loosening after a period of time, resulting in loosening and shaking between the connecting parts. Therefore, there is a need for a bolt and nut fastener that is easy to install and can effectively prevent the loose fit of the bolt and nut, so as to solve the problems existing in the prior art.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: steel heat treatment, all carbon steel hexagonal nuts for fasteners, high-strength pins, Aucklandring nuts and other products, we can provide you with suitable products Your fastener solution.
