Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a traction rope connector for fitness equipment. Background Art

[0002] In the field of fitness equipment, traction ropes, limiting balls, limiting plates, hooks and pull rings are usually involved. The limiting plate is arranged in the limiting ball and has a through hole in the middle. The tail of the traction rope is connected to the resistance output mechanism in the fitness equipment, the rope head extends into the limiting ball and passes through the through hole, the rope head is knotted, and the limiting ball is connected to the pull ring through the hook.

[0003] At present, the connection between the traction rope and the limiting ball is mainly achieved through the cooperation of knotting the rope end and perforating the holes. This connection method leads to limited fastening force between the traction rope and the limiting ball. After long-term use, the knot at the rope end may be compressed and deformed and pass through the perforation, and then the traction rope may fall off from the limiting ball, thereby affecting the fitness effect and the service life of the fitness equipment. In severe cases, it may also cause sports injuries to the fitness enthusiasts, such as strain caused by sudden falling off. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a traction rope connector for fitness equipment, which has a simple structural design and a more secure connection between the traction rope and the limiting ball.

[0006] Furthermore, the through hole comprises an input section, a tightening section and an output section which are sequentially connected from bottom to top, and a tightening assembly is provided in the tightening section to self-tighten the traction rope.

[0007] Furthermore, the tightening assembly includes a knot and a tightening block, the knot is arranged on the upper part of the traction rope, the tightening block is slidably matched with the tightening section, the inner diameter of the tightening section gradually decreases from top to bottom, the tightening blocks are two pieces, which are arranged opposite to each other, and vertical grooves are opened on the opposite sides, the bottom of the groove is in contact with the outer wall of the traction rope, the top surface of the knot is in contact with the top of the tightening section, and its bottom surface is in contact with the top surface of the tightening block.

[0008] Furthermore, the transverse cross section of the tightening block is in the shape of a semicircular ring.

[0009] Furthermore, the transverse cross section of the groove is in the shape of a semicircular arc.

[0010] Furthermore, a sealing ring is embedded in the input section, and the inner ring of the sealing ring contacts the outer wall of the traction rope.

[0011] Furthermore, a clamping assembly is provided at the bottom of the limiting ball, and the clamping assembly is arranged above the sealing ring. The clamping assembly includes two bolts. The bottom of the limiting ball is relatively provided with transverse threaded holes, and the threaded holes are connected to the input section.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model ties the top end of the traction rope to the middle of the bottom end of the connecting ring. Compared with the connection method of knotting the rope end and punching the hole, the connection between the traction rope and the limiting ball is more secure, thereby ensuring the fitness effect and the service life of the fitness equipment, and avoiding sports injuries caused by the sudden fall of the traction rope;

[0014] (2) The utility model forms a secondary limit by setting a tightening component.

DETAILED DESCRIPTION

[0024] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Example 1

[0026] like Figure 1 As shown, a traction rope connector for fitness equipment includes a limiting ball 1, a connecting ring 2 and a traction rope 3. A vertical through hole 4 is opened in the middle of the bottom end of the limiting ball 1. The bottom end of the connecting ring 2 is embedded in the top end of the limiting ball 1. The top end of the traction rope 3 passes through the through hole 4 and is tied to the middle of the bottom end of the connecting ring 2. By tying the top end of the traction rope 3 to the middle of the bottom end of the connecting ring 2, the connection between the traction rope 3 and the limiting ball 1 is more secure compared to the connection method of knotting the rope head and punching, thereby ensuring the fitness effect and the service life of the fitness equipment, and avoiding sports injuries caused by the sudden fall of the traction rope 3.

[0027] Example 2

[0028] This embodiment is improved on the basis of embodiment 1, such as Figure 2-Figure 4 As shown, the through hole 4 includes an input section 41, a tightening section 42 and an output section 43 connected in sequence from bottom to top, and a tightening assembly 5 is provided in the tightening section 42 to self-tighten the traction rope 3. The tightening assembly 5 includes a knot 51 and a tightening block 52. The knot 51 is arranged on the upper part of the traction rope 3, and the tightening block 52 is slidably matched with the tightening section 42. The inner diameter of the tightening section 42 gradually decreases from top to bottom. The tightening block 52 consists of two pieces, which are arranged opposite to each other, and vertical grooves 6 are provided on the opposite sides. The bottom of the groove 6 contacts the outer wall of the traction rope 3, and the top surface of the knot 51 contacts the top of the tightening section 42, and its bottom surface contacts the top surface of the tightening block 52. Specifically, the transverse cross section of the tightening block 52 is semicircular; the transverse cross section of the groove 6 is semicircular. By setting the tightening component 5, a secondary limit is formed. When the traction rope 3 tends to fall, the knot 51 pushes the tightening block 52 to move downward slightly, so that the two tightening blocks 52 gradually clamp the traction rope 3 radially, thereby further improving the connection and tightening force between the traction rope 3 and the limiting ball 1.

[0029] like Figure 3 As shown, in order to prevent impurities from entering the through hole 4 and ensure the performance of each tightening component in the through hole 4, a sealing ring 7 is embedded in the input section 41, and the inner circle of the sealing ring 7 contacts the outer wall of the traction rope 3.

[0030] Example 3

[0031] like Figure 5 and Figure 6 As shown, this embodiment adds a tightening component 8 on the basis of Embodiment 2. The tightening component 8 is arranged at the bottom of the limiting ball 1. The tightening component 8 is arranged above the sealing ring 7. The tightening component 8 includes two bolts. The bottom of the limiting ball 1 is relatively provided with transverse threaded holes 9. The threaded holes 9 are connected to the input section 41. The bolt threads are arranged in the threaded holes 9, and the ends of the bolts close to the input section 41 are in contact with the traction rope 3. By setting the tightening component 8, three limits are formed, and the traction rope 3 is radially tightened, thereby further improving the connection and fastening force between the traction rope 3 and the limiting ball 1. By rotating the bolts, the clamping force of the traction rope 3 can be adjusted. Specifically, there can be three or four bolts.

[0032] It should be noted that, by tying the top end of the traction rope 3 to the connecting ring 2, and cooperating with the tightening component 5 and the pressing component 8, the traction rope 3 is clamped at multiple locations, the force is dispersed, and damage or breakage of the traction rope 3 caused by excessive clamping force at a certain location is avoided.

[0033] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
