Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to an anti-dropping bolt. Background Art

[0002] Bolts are cylindrical threaded fasteners that are matched with nuts. A type of fastener consisting of a head and a rod, which must be matched with a nut to fasten and connect two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] The existing bolt is a separate fastener structure, but its sealing performance is poor when it is installed in combination. At the same time, its own fastening effect is poor when it is installed by twisting. After the two are connected for a long time, there is a risk of falling off. 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 purpose, the utility model anti-dropping bolt includes:

[0006] A rod body having threads and a smooth rod formed thereon;

[0007] a bolt head, which is disposed at one end of the rod body and faces the bare rod side of the rod body, and the bolt head is integrally formed with the rod body; and

[0008] The positioning assembly is formed on the polished rod and includes an elastic sheet arranged circumferentially, one end of the elastic sheet is connected to the rod body, and the nut can slide through the elastic sheet. By arranging the elastic sheet, the nut passes through the elastic sheet on the polished rod and is screwed with the thread for positioning, and the elastic sheet is reset, which can effectively prevent the screw from loosening and falling off.

[0009] A further improvement of the anti-dropping bolt of the utility model lies in that the bolt head is a hexagonal prism.

[0010] A further improvement of the anti-dropping bolt of the utility model lies in that a washer is sleeved on the rod body.

[0011] The beneficial effects of the utility model are:

[0012] By arranging the elastic sheet, the nut passes through the elastic sheet on the polished rod and is screwed with the thread for positioning, and the elastic sheet is reset, which can effectively prevent the screw from loosening and falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the utility model.

[0014] Among them, 1 is a rod body, 11 is a thread, 12 is a smooth rod, 2 is a bolt head, and 3 is an elastic sheet. DETAILED DESCRIPTION

[0015] 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.

[0016] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0017] like Figure 1 As shown, the anti-drop bolt includes:

[0018] A rod body 1, on which a thread 11 and a polished rod 12 are formed;

[0019] A bolt head 2 is disposed at one end of the rod body and faces the bare rod side of the rod body, and the bolt head and the rod body are integrally formed; and

[0020] The positioning assembly is formed on the polished rod and includes a circumferentially arranged elastic sheet, one end of which is connected to the rod body, and the nut can slide through the elastic sheet 3. By setting the elastic sheet, the nut passes through the elastic sheet on the polished rod and is screwed with the thread for positioning, and the elastic sheet is reset, which can effectively prevent the screw from loosening and falling off.

[0021] Specifically, the bolt head is a hexagonal prism.

[0022] Specifically, a washer is sleeved on the rod body.

[0023] 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. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0024] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
