Description

Technical Field

[0001] The utility model relates to the technical field of studs, in particular to an anti-deformation stud. Background Art

[0002] A stud is a headless fastener with external threads at both ends. It is usually used to connect two parts with through holes. One end is screwed into the part with the internal thread hole, and the other end passes through the part with the through hole, and then a nut is screwed on to tighten the connection. There are many kinds of studs currently available on the market, but there are still some disadvantages.

[0003] The existing studs can improve the stability of the installation of the studs and the connection objects by setting adjustable through holes. However, this adjustment setting allows the threaded rod to rotate to adjust the position of the slider. When the studs and the connection objects are installed together, there will be vibrations, which will cause the threaded rod to rotate and the slider to move. At the same time, the annular spring gasket is set in the column head to prevent the studs from being deformed after installation. When the general annular spring gasket is installed, it is difficult to disassemble. Once it is damaged later, it cannot be quickly disassembled and replaced. In addition, in order to prevent the studs from loosening during installation, it is often Low-carbon steel wires are used to connect a group of stud heads in series, but generally low-carbon steel wires are inconvenient to install and disassemble. For example, the Chinese utility model patent with the authorization announcement number CN210240251U discloses a stud, including a stud head and a column connected to the stud head, the column side wall is spirally provided with an external thread along the length direction, the column side wall is provided with a through hole, a slider is slidably provided in the through hole, the column is provided with a sliding control component for controlling the slider to slide in the through hole along the length direction of the column, and the slider is provided with an opening perpendicular to the length direction of the column. The utility model provides a stud that is easy to adjust the opening position, easy to use and low in cost. However, this stud is adjustable by setting a through hole, which can improve the stability of the installation of the stud and the connection. This adjustment setting allows the threaded rod to rotate to adjust the position of the slider. After the stud and the connection are installed together, there will be vibration, which will cause the threaded rod to rotate and the slider to move. At the same time, the annular spring gasket is set in the column head to prevent the stud from being deformed after installation. When a general annular spring gasket is installed, it is difficult to disassemble. Once it is damaged later, it cannot be quickly disassembled and replaced. In addition, in order to prevent the stud from loosening during installation, a group of stud heads are often connected in series with low-carbon steel wire. However, the installation and disassembly of general low-carbon steel wire are inconvenient. Therefore, we propose an anti-deformation stud to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a deformation-proof stud to solve the problems in the above-mentioned background technology. For the current stud, through the setting of through holes, it can be adjusted, which can improve the installation stability of the stud and the connector.

When the stud and the connector are installed together, there will be vibrations, which may cause the threaded rod to rotate and the slider to move. At the same time, by setting an annular spring gasket inside the stud head, the deformation of the stud after installation can be prevented. However, when the general annular spring gasket is installed, it is difficult to disassemble. Once it is damaged later, it cannot be quickly disassembled and replaced. In addition, in order to prevent the stud from loosening during installation, low-carbon steel wires are often used to connect a group of stud heads in series.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0031] Embodiment 1: To solve the problems existing in the prior art, the present embodiment adopts the following technical solutions. An anti-deformation stud is provided with a stud body 1; an anti-deformation mechanism is arranged on the outer side of the left side of the stud body 1, which can be symmetrically clamped and installed on the outer side of the left side of the stud body 1 front and back, can prevent the stud body 1 from deforming, and is convenient for disassembly and installation, so that once the first spring washer 9 and the second spring washer 10 are damaged, they can be quickly replaced; a loosening prevention mechanism is arranged inside the right side of the stud body 1, which can adjust the position by moving left and right, facilitating improving the stability of the installation of the stud body 1 and connectors of different sizes; a wire series connection mechanism is arranged inside the stud head 13, facilitating the winding of low-carbon steel wires and convenient for connecting multiple groups of stud heads 13 together to restrict each other. First, an opening hole 2 is opened inside the right side of the stud body 1, a fixing rod 3 is installed inside the opening hole 2, a moving block 5 is slidably installed on the outer side of the fixing rod 3, and limiting holes 4 are equidistantly opened inside the fixing rod 3. Limiting holes 4 are also arranged inside the moving block 5, and the position of the moving block 5 can be slidably adjusted according to the positions of connectors of different sizes. After the adjustment is completed, a limiting rod 6 is inserted into the limiting hole 4 for limiting. Before the limiting rod 6 is inserted into the limiting hole 4, the unfolded rotating rod 7 is first moved inward for combination, so that the rotating rod 7 and the limiting rod 6 are on the same horizontal plane, and then the limiting rod 6 is inserted into the limiting hole 4. When the limiting rod 6 is inserted into the limiting hole 4, the rotating rod 7 is released. Since a spring body 8 is arranged inside the rotating rod 7 and the spring body 8 has elasticity, that is, the spring body 8 will cause the rotating rod 7 to unfold, that is, the limiting rod 6 is stably clamped inside the limiting hole 4. At the same time, a first spring washer 9 is arranged on the left side of the stud body 1, the second spring washer 10 is clamped and connected behind the first spring washer 9, and the first spring washer 9 and the second spring washer 10 are closely attached to the outer side of the left side of the stud body 1. In addition, connecting blocks 11 are symmetrically arranged on the upper and lower sides of the outer side of the second spring washer 10. By rotating the connecting blocks 11 inward, the connecting blocks 11 can be engaged with the connecting grooves 12. When the stud body 1 is installed and connected, the first spring washer 9 and the second spring washer 10 are flattened to generate longitudinal elastic force, which will provide a certain pre-tightening force. When the connector is subjected to vibration and impact, the first spring washer 9 and the second spring washer 10 can absorb part of the energy, reduce the impact on the connector, and prevent the stud body 1 from deforming and loosening during installation. Secondly, a stud head 13 is installed on the left side of the stud body 1. A limiting groove 14 is opened inside the stud head 13, a fixing block 15 is installed above the limiting groove 14, and a fixing hole 16 is opened inside the fixing block 15. Low-carbon steel wires can be inserted into the fixing hole 16 for tightening, and then wound around the outer side of the limiting groove 14, so that multiple groups of stud heads 13 can be connected in series together, making the installation of the stud body 1 stable.

[0032] The existing stud can be adjusted by setting through holes, which can improve the installation stability of the stud body 1 and the connector. However, this adjustment setting allows the threaded rod to rotate to adjust the position of the slider. After the stud body 1 is installed with the connector, there will be vibrations, which may cause the threaded rod to rotate and the slider to move. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 3 and Figure 6 shown, the anti-loosening mechanism includes a through hole 2 provided inside the right side of the stud body 1. A fixed rod 3 is fixedly installed inside the through hole 2. A plurality of limiting holes 4 are equidistantly provided inside the fixed rod 3. At the same time, a moving block 5 is provided outside the fixed rod 3. The moving block 5 can slide outside the fixed rod 3. At the same time, limiting holes 4 are also provided inside the moving block 5. The moving block 5 can move left and right outside the fixed rod 3. The moving block 5 can enable the stud body 1 to be tightly connected when connected to connectors of different sizes. After the position of the moving block 5 is adjusted, the limiting hole 4 inside the moving block 5 is aligned with the limiting hole 4 provided inside the fixed rod 3. Then, a limiting rod 6 is inserted into the limiting hole 4. Since the rotating rods 7 are rotatably installed on the front and rear sides of the limiting rod 6, and a spring body 8 is provided inside the rotating rod 7. The spring body 8 has elasticity. When the limiting rod 6 needs to be inserted into the moving block 5, at this time, the spring body 8 is contracted together, and the rotating rods 7 on the upper and lower sides are combined together. After the limiting rod 6 is inserted into the limiting hole 4, the rotating rod 7 is released, and the spring body 8 will rebound, and the rotating rod 7 will expand up and down. In this way, the limiting rod 6 will be firmly inserted into the limiting hole 4, that is, the stud body 1 and the connector will be firmly connected together.

[0033] Embodiment 2: For the existing stud, the first spring washer 9 and the second spring washer 10 are arranged inside the connecting block 11, which can prevent the stud body 1 from deforming after installation. When the first spring washer 9 and the second spring washer 10 are generally difficult to disassemble during installation, once they are damaged subsequently, they cannot be quickly disassembled and replaced. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 2 and Figure 5 shown, the anti-deformation mechanism includes a first spring washer 9 provided in front of the left side of the stud body 1. A second spring washer 10 is provided behind the first spring washer 9. The first spring washer 9 and the second spring washer 10 are snap-fitted together and closely attached to the outer side of the left side of the stud body 1. At the same time, connecting blocks 11 are rotatably installed on the upper and lower sides of the second spring washer 10. Secondly, connecting grooves 12 are provided on the upper and lower sides inside the first spring washer 9, that is, by rotating the connecting block 11, the connecting block 11 can be snap-fitted with the connecting groove 12, improving the installation stability of the first spring washer 9 and the second spring washer 10.

[0034] Embodiment 3: For existing studs, in order to prevent the loosening of the installation of the stud body 1, a group of stud heads 13 are often connected in series by low-carbon steel wire. However, there are problems such as inconvenience in the installation and disassembly of general low-carbon steel wire. Therefore, in this embodiment, the following technical solutions are adopted, as Figure 1 , Figure 2 and Figure 6 shown. The wire series connection mechanism includes a stud head 13 installed on the left side of the stud body 1. A limit groove 14 is opened inside the stud head 13. A fixing block 15 is fixedly installed above the limit groove 14. A fixing hole 16 is opened inside the fixing block 15. The low-carbon steel wire can be inserted into the fixing hole 16 for fastening, and then the fixing hole 16 is wound around the inside of the limit groove 14 in circles, which is convenient for the wire to be wound and facilitates the connection of multiple groups of stud heads 13.
