AI Technical Summary
When existing double-headed bolts need to be replaced after thread wear, the intermediate rod body must be discarded, resulting in waste of resources.
A double bolt head bolt is designed. By setting a slidingly connected fixing rod and mounting rod on the connecting rod and installing fixing bolts on the connecting rod, the fixing rod, the fixing rod and the mounting rod are achieved. When it is necessary to replace the screw, you only need to remove the fixing bolts to retain the reusability of the connecting rod.
It realizes that the intermediate rod body is not necessary to be discarded when replacing the screw, which reduces resource waste and simplifies the screw disassembly and assembly process.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolts, in particular to a double-bolt head bolt. Background Art
[0002] Stud bolts are also called double-headed screws or double-headed studs. They are used to connect mechanical fixed links. Stud bolts have threads on both ends, and the screw in the middle can be thick or thin. They are generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, crane towers, large-span steel structures and large buildings.
[0003] The applicant found that the existing two-side threads and the middle rod body are integrally formed. When the two-side threads need to be replaced after being worn, the middle rod body needs to be discarded at the same time, which leads to a waste of resources. In order to recycle the middle rod body, we propose a double-bolt head bolt. Utility Model Content
[0004] The utility model aims to provide a double-bolt head bolt to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a double-bolt head bolt, comprising a connecting rod, both sides of which are fitted and connected with screw rods;
[0006] A fixing rod is arranged on one side of the screw rod, and a mounting rod is arranged on the other side of the screw rod, and both the fixing rod and the mounting rod are slidably connected in the connecting rod;
[0007] The connecting rod is provided with a fixing bolt, and the fixing bolt is connected to both the fixing rod and the mounting rod.
[0008] As a preferred solution of the double-bolt head bolt described in the utility model, wherein: the fixing rod is provided with an insertion hole, and the installation rod is inserted into the insertion hole.
[0009] As a preferred solution of the double-bolt head bolt described in the utility model, a through hole is opened in the middle of the connecting rod, and fixing frames are arranged on the front and rear inner walls of the through hole, and the fixing bolts are arranged on the fixing frames on both sides.
[0010] As a preferred solution of the double-bolt head bolt described in the utility model, the opposite sides of the fixing frames on both sides are in contact with the fixing rod, and the fixing rod and the mounting rod both extend into the through hole.
[0011] As a preferred solution of the double-bolt head bolt described in the utility model, wherein: the fixing frame is a cross-shaped structure.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. A fixing rod and a mounting rod which are slidably connected to the connecting rod are respectively arranged on the screw rods on both sides, and the fixing rod can be sleeved on the mounting rod, so that the connecting rod, the fixing rod and the mounting rod can be fixed together by installing a fixing bolt on the connecting rod. When the screw rod needs to be replaced, only the fixing bolt needs to be removed, so that the connecting rod can be reused;
[0014] 2. By setting a through hole on the connecting rod, it is convenient for workers to disassemble and install the fixing bolts, thereby fixing the fixing rod and the installation rod, thereby fixing the screw rods on both sides. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the overall structure of a double-bolt head bolt of the utility model;
[0016] Figure 2 It is a schematic diagram of the enlarged local structure of a double-bolt head bolt of the utility model.
[0017] In the figure: 1. connecting rod; 2. screw rod; 3. fixing rod; 4. mounting rod; 5. fixing bolt; 6. through hole; 7. fixing bracket. DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] As mentioned in the background technology, in view of the problem that it is inconvenient to recycle the intermediate rod body in the prior art, the utility model provides a double-bolt head bolt.
[0020] Example 1
[0021] Reference Figure 1 to Figure 2 , a double-bolt head bolt, comprising, a connecting rod 1, both sides of the connecting rod 1 are fitted and connected with screw rods 2;
[0022] A fixing rod 3 is arranged on one side of the screw rod 2, and a mounting rod 4 is arranged on the other side of the screw rod 2, and both the fixing rod 3 and the mounting rod 4 are slidably connected in the connecting rod 1;
[0023] A fixing bolt 5 is provided on the connecting rod 1, and the fixing bolt 5 is connected to both the fixing rod 3 and the mounting rod 4. By installing the fixing bolt 5 on the connecting rod 1, the connecting rod 1, the fixing rod 3 and the mounting rod 4 can be fixed together. When the screw rod 2 needs to be replaced, only the fixing bolt 5 needs to be removed, so that the connecting rod 1 can be reused to reduce the waste of resources.
[0024] The fixing rod 3 is provided with an insertion hole, and the mounting rod 4 is inserted into the insertion hole, so that the fixing rod 3 can be sleeved on the mounting rod 4, so that the two can be fixed together by the fixing bolt 5.
[0025] A through hole 6 is opened in the middle of the connecting rod 1, and fixing frames 7 are provided on the inner walls on both sides of the through hole 6. Fixing bolts 5 are arranged on the fixing frames 7 on both sides. The through hole 6 is provided to facilitate workers to disassemble and assemble the fixing bolts 5, so as to fix the fixing rod 3 and the installation rod 4, thereby fixing the screw rods 2 on both sides.
