Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a new type of bolt. Background Technique
[0002] A bolt is a mechanical part, a cylindrical threaded fastener used with a nut. A type of fastener composed of two parts, a head and a screw rod (a cylinder with external threads), which needs to cooperate with a nut for fastening and connecting two parts with through holes.
[0003] When installing two connecting parts with the existing bolt, it is fixed by a nut. When working for a long time, wear will occur between the nut and the bolt, causing the nut to become loose. Summary of the Invention
[0004] The purpose of the utility model is to provide a new type of bolt with good stability for the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of bolt includes a bolt body and a nut. The nut is threadedly connected to the bolt body. It is characterized in that a second bolt is arranged in the bolt body, a slot for installing the second bolt is opened on the bolt body, the front end of the second bolt extends out of the bolt body and passes through the nut, a hole for the second bolt to pass through and cooperate with it is opened on the nut, a positioning component for fixing the second bolt is arranged at the upper end of the bolt body. The positioning component consists of a positioning rod and a connecting spring. An installation slot for installing the positioning component is opened on the bolt body. The positioning rod and the return spring are both arranged in the installation slot, and a positioning hole for cooperating with the positioning rod is opened on the side wall of the second bolt.
[0006] In the above new type of bolt, one end of the positioning rod extends out of the installation slot and mates with the positioning hole of the second bolt. The other end of the positioning rod extends out of the bolt body and is connected with a pull rod. The return spring is arranged between the positioning rod and the bolt body, and the positioning rod shrinks in the installation slot under the action of the return spring.
[0007] In the above new type of bolt, external threads are opened at the outer end of the bolt body, internal threads are opened on the nut, internal threads are opened on the hole of the nut, and external threads are opened on the second bolt.
[0008] Compared with the prior art, when installing the new type of bolt, the nut is fixed by the bolt body and the second bolt. When one of them wears, it will not affect the overall stability. Description of the Drawings
[0009] Figure 1 This is a schematic structural view of the present utility model.
[0010] In the figure, 1 is the bolt body; 2 is the nut; 3 is the second bolt; 4 is the opening; 5 is the positioning component; 6 is the positioning rod; 7 is the connecting spring; 8 is the positioning hole; 9 is the pull rod. Specific embodiments
[0011] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0012] As Figure 1 shown, the novel bolt includes a bolt body 1 and a nut 2, the nut 2 is threadedly connected to the bolt body 1, a second bolt 3 is arranged in the bolt body 1, a slot for installing the second bolt 3 is opened on the bolt body 1, the front end of the second bolt 3 extends out of the bolt body 1 and passes through the nut 2, an opening 4 for the second bolt 3 to pass through and cooperate with it is opened on the nut 2, a positioning component 5 for fixing the second bolt 3 is arranged at the upper end of the bolt body 1, the positioning component 5 is composed of a positioning rod 6 and a connecting spring 7, an installation slot for installing the positioning component 5 is opened on the bolt body 1, the positioning rod 6 and the return spring are both arranged in the installation slot, and a positioning hole 8 cooperating with the positioning rod 6 is opened on the side wall of the second bolt 3.
[0013] Further elaborating, one end of the positioning rod 6 extends out of the installation slot and mates with the positioning hole 8 of the second bolt 3, the other end of the positioning rod 6 extends out of the bolt body 1 and is connected with a pull rod 9, and the return spring is arranged between the positioning rod 6 and the bolt body 1, and the positioning rod 6 is retracted in the installation slot by the action of the return spring.
[0014] Further elaborating, when the nut 2 is fixed, it is simultaneously fixed to the bolt body 1 and the second bolt 3. Under long-term use, the bolt body 1 and the second bolt 3 simultaneously play a role in fixing the nut 2 and the connecting piece, enhancing the stability of the bolt during use.
[0015] Further elaborating, the second bolt 3 and the bolt body 1 are not connected by threads, but the second bolt 3 is fixed to the bolt body 1 through the positioning component 5 on the bolt body 1, avoiding wear between the bolt body 1 and the second bolt 3 under long-term work.
[0016] Further elaborating, an external thread is opened at the outer end of the bolt body 1, an internal thread is opened on the nut 2, an internal thread is opened on the opening 4 of the nut 2, and an external thread is opened on the second bolt 3.
[0017] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways of substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
[0018] Although terms such as bolt body 1, nut 2, second bolt 3, opening 4, positioning component 5, positioning rod 6, connecting spring 7, positioning hole 8, and pull rod 9 in the drawings are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
