Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double - headed screws, and specifically relates to a new type of double - headed screw. Background Technique
[0002] A double - headed screw, also called a double - headed bolt or double - headed stud, is used for the fixed connection function of machinery. Both ends of the double - headed bolt have threads, and the middle screw rod can be thick or thin. It is generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, long - span steel structures and large - scale buildings, etc.
[0003] The most common form of the existing double - headed screw is that there are threads at both ends and a smooth rod in the middle, which can be used for locking thread connections at both ends, and the directions of the two groups of threads are opposite.
[0004] For the above - mentioned technical conditions, there are still defects: Most of the double - headed screws in the prior art are used for the connection between two objects. When in use, an appropriate amount of lubricating oil is sprayed on them, and then they are inconvenient to place and take, reducing the use effect.
[0005] Based on this, the utility model designs a new type of double - headed screw to solve the above problems. Content of the Utility Model
[0006] The purpose of the utility model is to provide a new type of double - headed screw to solve the above - mentioned technical problems.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A new type of double - headed screw includes a screw rod body. A hexagonal block is arranged at the middle position of the screw rod body. Threaded parts are arranged on both sides of the screw rod body. End heads are arranged at both ends of the screw rod body. A positioning hole is opened on the hexagonal block.
[0008] By adopting the above - mentioned technical solution, the screw can be transferred through the positioning hole, reducing the influence on the lubricating oil on it.
[0009] Preferably, the positioning hole is a through - hole on the hexagonal block.
[0010] By adopting the above - mentioned technical solution, a silk thread can be passed through the positioning hole, improving the effect of taking and placing it.
[0011] Preferably, the screw rod body is integrally formed.
[0012] By adopting the above - mentioned technical solution, it has a relatively high use strength.
[0013] Preferably, chamfered corners are arranged on the outer sides of the two groups of end heads.
[0014] By adopting the above - mentioned technical solution, its use effect is increased.
[0015] In summary, the present application has the following beneficial technical effects: Through the provided positioning holes, it is possible to better pick up the double-headed screw after applying lubricating oil, and at the same time, it can perform pre-positioning during its installation. Then, through the provided hexagonal block, it is possible to increase the strength of the first threaded connection of the double-headed screw and improve the subsequent usage effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.
[0017] Figure 1 It is a schematic diagram of the overall structure of this embodiment;
[0018] Figure 2 It is a schematic diagram of the front structure of this embodiment.
[0019] In the drawings, the list of components represented by each reference numeral is as follows:
[0020] 1. Screw body; 2. Hexagonal block; 3. Threaded part; 4. End; 5. Positioning hole. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0022] The following combines the attached Figure 1-2 to further elaborate on the present application.
[0023] Refer to Figure 1 And Figure 2 , a new type of double-headed screw, including a screw body 1. A hexagonal block 2 is provided at the middle position of the screw body 1. The hexagonal block 2 can facilitate the threaded connection of the first threaded part 3, without directly contacting and tightening at the threaded place, improving the usage effect of the double-headed screw. Threaded parts 3 are provided on both sides of the screw body 1, and ends 4 are provided at both ends of the screw body 1. Positioning holes 5 are opened on the hexagonal block 2. The positioning holes 5 are used for picking up the double-headed screw after applying lubricating oil, reducing the damage of the applied lubricating oil and improving the subsequent connection effect.
[0024] Refer to Figure 1, the positioning hole 5 is a through hole on the hexagonal block 2, the screw body 1 is integrally formed, and chamfered edges are provided on the outer sides of the two groups of end heads 4.
[0025] The implementation principle of this embodiment is as follows: When in use, apply an appropriate amount of lubricating oil to the threaded portion 3 on the double-headed screw, and then insert a round rod through the positioning hole 5 to pick up and place the double-headed screw. When installing for the first time, one end can be pre-installed through the round rod. When further tightening is required later, pull out the round rod, clamp the hexagonal block 2 with a hexagonal tool, and then rotate it, which can further increase the tightening degree of one end of the screw, and then install the screw at the other end.
