Description

Technical Field

[0001] This utility model relates to the technical field of fitness equipment, and in particular to a tensioner connector. Background Technology

[0002] Resistance bands are commonly used equipment in home fitness and gym training. They achieve muscle training through the tension of the rope. The connector is the core component that connects the rope to the handle, and its convenience and stability directly affect the user experience and safety.

[0003] Currently, most resistance bands on the market use pin-type, threaded, or snap-on connectors. Pin-type connectors require manual insertion and removal of the pin, which is cumbersome and the pin is easily lost. Threaded connectors require multiple rotations to complete the connection, resulting in low operational efficiency. While snap-on connectors are relatively convenient to connect, most require pressing an additional button to disassemble, making the operation less smooth. Therefore, designing a resistance band connector that balances ease of operation, stable connection, and quick assembly / disassembly to address the shortcomings of existing resistance band connectors and improve the user's fitness experience is an urgent technical problem to be solved. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a tensioner connector.

[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions: A tensioner connector includes a connector base and a handle. The bottom of the connector base is connected to the tensioner via a rope. The handle is located on the top of the connector base and provides a gripping space. The connector base also includes a connecting ring and a connecting shaft. The connecting ring is fixedly connected to the top of the connector base. A vertically sliding abutment post is slidably connected inside the connector base, extending through to the top of the connector base. A spring is vertically installed inside the connector base at a position below the abutment post. One end of the spring is fixedly connected inside the connector base, and the other end is fixedly connected to the bottom of the corresponding abutment post, so that the abutment post has an upward sliding tendency. The connecting shaft passes through the connecting ring and is provided with a connector for connecting the handle. The abutment post is used to press the connecting shaft against the inside of the connecting ring. A notch is left between the connecting ring and the connector base for the connecting shaft to pass through.

[0006] Preferably, the side of the top of the abutment post away from the connecting ring is provided with an arc transition.

[0007] Preferably, the top of the abutment post near the connecting ring has a planar structure, which is used to fit tightly against the outer peripheral wall of the connecting shaft.

[0008] Preferably, there are two connecting rings, two abutment posts and two springs symmetrically arranged. The two connecting rings are spaced apart on the top of the connecting seat. The connecting shaft passes through the inside of the two connecting rings. The connecting member is fixedly connected to the middle of the connecting shaft and extends out from the gap between the two connecting rings to the outside.

[0009] Preferably, a linkage rod is fixedly connected between the two abutting posts, and a sliding chamber is provided inside the connecting seat for the linkage rod to slide vertically.

[0010] Preferably, the connecting seat and the connecting ring are fixedly connected by integral molding.

[0011] Preferably, the bottom of the connector has a fixing hole, and a crimping member is provided inside the connector at the position corresponding to the fixing hole. The rope passes through the fixing hole and is fixedly connected to the crimping member. The size of the crimping member is larger than the fixing hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves connection through the cooperation of a connecting seat, a connecting ring, a spring-driven abutment post, and a connecting shaft. During connection, the connecting shaft presses against the abutment post through the notch between the connecting ring and the connecting seat, causing the spring to compress and enter the connecting ring. Then, the spring returns to its original position, driving the abutment post to press the connecting shaft tightly. During use, the connecting ring acts as the main force-bearing component, ensuring the stability of the connection. During disassembly, only force needs to be applied to the connecting shaft to squeeze the abutment post and unlock it, without the need for additional operation buttons. Compared with existing pin-type, threaded, and snap-on connectors, this invention solves the problems of cumbersome operation, easy loss of parts, and low efficiency, thereby improving the user's ease of operation and fitness experience when using the resistance band.

[0018] The following is a reference appendix. Figure 1 To be continued Figure 2 This application describes a tensioner connector.

[0019] like Figure 1 and Figure 2As shown, the tensioner connector includes a connecting seat 1 and a handle (not shown in the figure). The bottom of the connecting seat 1 is connected to the tensioner via a rope 2. The handle is located on the top of the connecting seat 1 and provides a gripping space. It also includes a connecting ring 3 and a connecting shaft 4. The connecting ring 3 is integrally formed and fixedly connected to the top of the connecting seat 1 to improve the structural strength of the connecting seat 1 and the connecting ring 3. A vertically sliding abutment post 5 is connected inside the connecting seat 1, and the abutment post 5 slides through to the top of the connecting seat 1. A spring 6 is vertically installed inside the connecting seat 1 at a position below the corresponding abutment post 5. One end of the spring 6 is fixedly connected inside the connecting seat 1 and the other end is fixedly connected to the bottom of the corresponding abutment post 5. To allow the abutment post 5 to slide upwards, the connecting shaft 4 passes through the inside of the connecting ring 3 and is provided with a connector 7 for connecting the handle. The abutment post 5 is used to press the connecting shaft 4 against the inside of the connecting ring 3. A notch 8 is left between the connecting ring 3 and the connecting seat 1 for the connecting shaft 4 to pass through. The connecting shaft 4 can press against the abutment post 5 through the notch 8 between the connecting ring 3 and the connecting seat 1, so that the spring 6 is compressed and enters the connecting ring 3. The spring 6 returns to its original position and drives the abutment post 5 to press the connecting shaft 4 against the connecting ring 3, thereby realizing the quick disassembly and assembly and stable connection of the connector. This solves the defects of existing connectors, such as cumbersome operation, easy loss of parts, and low efficiency, and takes into account both operation convenience and connection stability.

[0020] Preferably, the side of the top of the abutment post 5 away from the connecting ring 3 is provided with an arc transition. When the connecting shaft 4 abuts against the abutment post 5, the arc transition area can be used for guidance, reducing the abutment resistance between the connecting shaft 4 and the abutment post 5, making the insertion operation of the connecting shaft 4 smoother and less strenuous, and improving the user's operating experience.

[0021] Furthermore, the top of the abutment post 5 near the connecting ring 3 has a planar structure. The planar structure is used to fit tightly against the outer peripheral wall of the connecting shaft 4. Through the planar structure at the top of the abutment post 5, it can form a close contact with the outer peripheral wall of the connecting shaft 4, increasing the contact area between the abutment post 5 and the connecting shaft 4, enhancing the clamping effect of the abutment post 5 on the connecting shaft 4, preventing the connecting shaft 4 from shaking during use, and improving the stability of the connection.

[0022] Preferably, there are two symmetrically arranged connecting rings 3, abutting posts 5, and springs 6. The two connecting rings 3 are spaced apart at the top of the connecting seat 1. The connecting shaft 4 passes through the two connecting rings 3. The connecting piece 7 is fixedly connected to the middle of the connecting shaft 4 and extends outward from the gap between the two connecting rings 3. The connecting shaft 4 is limited from both sides by the double connecting rings 3 and the double abutting posts 5. After the connecting shaft 4 passes through the double connecting rings 3, it is simultaneously tightened by the double abutting posts 5. The connecting piece 7 extends out from the gap between the double connecting rings 3, which can enhance the force balance and connection firmness of the connecting shaft 4, avoid the risk of loosening caused by uneven force on a single connecting ring 3, and ensure the stable connection of the connector.

[0023] Furthermore, a linkage rod 9 is fixedly connected between the two abutting posts 5. The connecting seat 1 has a sliding chamber 10 for the linkage rod 9 to slide vertically. The linkage rod 9 can drive the two abutting posts 5 to slide vertically along the sliding chamber 10 synchronously, which can ensure the consistency of the action of the two abutting posts 5, avoid the problem of the connecting shaft 4 being stuck or unevenly pressed due to the asynchronous sliding of a single abutting post 5, and improve the operational stability of the connector.

[0024] In addition, a fixing hole 11 is provided at the bottom of the connecting seat 1, and a crimping member 12 is provided inside the connecting seat 1 at the position corresponding to the fixing hole 11. The rope 2 passes through the fixing hole 11 and is fixedly connected to the crimping member 12. The size of the crimping member 12 is larger than that of the fixing hole 11. The crimping member 12 limits and fixes the rope 2 in the fixing hole 11 by limiting its size, which can enhance the connection between the rope 2 and the connecting seat 1, avoid the risk of the rope 2 falling off the connecting seat 1 during the use of the tensioner, and improve the safety of use.

[0025] This invention achieves connection through the cooperation of a connecting seat 1, a connecting ring 3, a spring 6-driven abutment post 5, and a connecting shaft 4. During connection, the connecting shaft 4 presses against the abutment post 5 through the notch 8 between the connecting ring 3 and the connecting seat 1, causing the spring 6 to compress and enter the connecting ring 3. Then, the spring 6 returns to its original position, driving the abutment post 5 to press the connecting shaft 4 tightly. During use, the connecting ring 3 acts as the main force-bearing component to ensure the stability of the connection. During disassembly, only force needs to be applied to the connecting shaft 4 to squeeze the abutment post 5 to unlock it, without the need for additional operation buttons. Compared with existing pin-type, threaded, and snap-on connectors, this invention solves the problems of cumbersome operation, easy loss of parts, and low efficiency, thereby improving the user's ease of operation and fitness experience when using the resistance band.

[0026] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
