AI Technical Summary
During use, existing bolts are prone to loosening and falling off the nuts due to jitter or stress, and are affected by the environment, such as wind and rain corrosion, resulting in a decrease in the fixing strength, which causes the fastener to fall off.
An anti-fall fastener is designed, including a stud in the hollow chamber, a nut in communication with the stud, and a positioning assembly in the middle of the stud. The positioning assembly includes a bump arranged in the stud chamber circumferentially, a mounting groove for the bump to penetrate, a chamber with internal threads and a positioning column. By moving the nut to the direction of the nut, the positioning column extends into the installation groove of the stud, and pushing the bump outward to the outside of the stud, effectively preventing the nut from loosening and falling off.
Effectively prevent the nut from loosening and falling off, strengthen the fixing strength of the fastener and reduce the falling off of the fastener due to environmental influences.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, in particular to an anti-falling fastener. Background Art
[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw, which must be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection; it can be divided into hexagonal head bolts, round head bolts, square head bolts, countersunk bolts, etc. according to the shape of the head.
[0003] During use, the current bolts are affected by the use environment, vibration or stress, which can easily cause the nuts to loosen and fall off. The falling off of the nuts can easily cause the bolts to detach, causing the fasteners to lose their fixing function. In addition, during use, they are affected by the environment such as wind and rain, which can cause corrosion. At this time, the fixing strength of the fasteners will be reduced, causing the fasteners to fall off. The inventors have proposed improvements to this. Utility Model Content
[0004] The utility model aims to provide an anti-falling bolt which has a reasonable structure and can effectively prevent the bolt from falling off and loosening.
[0005] In order to achieve the above-mentioned utility model object, the utility model provides an anti-falling fastener, comprising:
[0006] a stud formed with a hollow chamber;
[0007] a nut mounted on one end of the stud and communicating with the stud chamber; and
[0008] The positioning assembly is formed in the middle of the stud, and includes a protrusion circumferentially arranged in the stud cavity. The stud is formed with a mounting groove for the protrusion to pass through, and the protrusion can extend out of the stud. The stud cavity is provided with a thread, and a positioning column is screwed in the cavity, and the positioning column presses against the protrusion. The nut is screwed to the nut direction through the stud, and the positioning column extends into the stud mounting groove, pushing the protrusion outward of the stud, which can effectively prevent the nut from loosening and falling off.
[0009] A further improvement of the anti-dropping fastener of the utility model is that an inclined surface pressed against the positioning column is formed on the projection.
[0010] A further improvement of the anti-drop-off fastener of the utility model lies in that the positioning column is threadedly installed in the stud cavity.
[0011] A further improvement of the anti-drop-off fastener of the utility model lies in that a retaining edge is arranged on one side of the protrusion to prevent the protrusion from falling off the stud.
[0012] The beneficial effects of the utility model are:
[0013] The nut is screwed into the direction of the nut through the stud, and the positioning column extends into the front installation groove of the stud to push the protrusion outward of the stud, which can effectively prevent the nut from loosening and falling off. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the utility model;
[0015] Figure 2 for Figure 1 Schematic diagram of the internal structure.
[0016] Among them, 1 is a stud, 11 is a hollow chamber, 2 is a nut, 3 is a positioning column, 31 is a protrusion, 32 is a rib, and 33 is an inclined surface. DETAILED DESCRIPTION
[0017] The present invention is further explained below in conjunction with specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0019] like Figure 1-2 As shown, an anti-falling fastener comprises:
[0020] A stud 1 formed with a hollow chamber 11;
[0021] A nut 2, which is mounted on one end of the stud and communicates with the stud chamber; and
[0022] The positioning assembly is formed in the middle of the stud, and includes a protrusion 31 circumferentially arranged in the stud cavity. A mounting groove for the protrusion to pass through is formed on the stud 1, and the protrusion can extend out of the stud 1. The stud cavity is provided with a thread, and a positioning column 3 is screwed in the cavity, and the positioning column 3 presses against the protrusion 31. The nut is screwed to the nut direction through the stud, and the positioning column extends into the mounting groove of the stud, pushing the protrusion outward of the stud, which can effectively prevent the nut from loosening and falling off.
[0023] Specifically, the protrusion is formed with an inclined surface 33 pressed against the positioning column.
[0024] Specifically, the positioning post is threadedly installed in the stud cavity.
[0025] Specifically, a retaining edge 32 is provided on one side of the protrusion to prevent the protrusion from falling off the stud.
[0026] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
