Description

Technical Field

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

[0002] In fitness equipment, especially strength training devices, resistance bands (also known as training ropes) are used. One end of the resistance band is fixed to the motor, and the other end connects to a resistance band connector. In current technology, the resistance band and connector are often glued together. While this prevents separation, it makes disassembly and maintenance difficult. Resistance bands are consumable parts with a limited lifespan, requiring replacement after that period. The difficulty in separating the resistance band from the connector obviously causes maintenance inconvenience. Furthermore, the glue is corrosive to the resistance band, affecting its lifespan. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pull rope connector that is easy to assemble and disassemble with a pull rope.

The main body has a clamping surface corresponding to the wire groove, and a pull rope clamping space is formed between the clamping surface and the wire groove. The main body is provided with a mounting mechanism for fixing external structural components.

[0007] Furthermore, the number of anti-slip protrusions is multiple.

[0008] Furthermore, the groove includes a main portion in the shape of a ring frame.

[0009] Furthermore, the cable groove also includes a rope end storage part connected to the main part, and the rope end storage part is provided with the anti-slip protrusion.

[0010] Furthermore, the main part is connected to the inlet hole, and the connection between the rope end storage part and the main part is located near the connection between the main part and the inlet hole.

[0011] Furthermore, the main body has a clamping cavity, the bottom of the mounting plate is housed in the clamping cavity, and the inner bottom surface of the clamping cavity forms the clamping surface.

[0012] Furthermore, the mounting plate is also equipped with a rubber pad.

[0013] Furthermore, the main body has a hook portion, and the mounting mechanism includes a latch, a first elastic element, and a rotating shaft. The latch is rotatably connected to the main body through the rotating shaft. The latch is used to close the inlet and outlet of the hook portion, and the first elastic element contacts the latch and the main body respectively.

[0014] Furthermore, the main body has a hook portion, an installation cavity, and a limiting groove. The mounting mechanism includes a sliding block, a limiting post, and a second elastic element.

[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1 to 6 A pull cord connector, including:

[0032] Mounting plate 1, the top of the mounting plate 1 is provided with a through-hole 11, the bottom surface of the mounting plate 1 is provided with a wire groove 12 that communicates with the through-hole 11, and the wire groove 12 is provided with a plurality of anti-slip protrusions 121.

[0033] The main body 2 is detachably connected to the mounting plate 1. The main body 2 has a clamping surface 21 corresponding to the wire groove 12, and a rope clamping space is formed between the clamping surface 21 and the wire groove 12. The main body 2 is provided with a mounting mechanism for fixing external structural components.

[0034] As can be seen from the above description, the beneficial effects of this utility model are as follows: This pull rope connector has a novel structure. After the end of the pull rope extends into the pull rope clamping space, the detachably connected mounting plate 1 and the main body 2 can firmly clamp and fix the pull rope without the need for glue, which greatly facilitates the disassembly and assembly of the pull rope and the pull rope connector, improves the maintenance efficiency of fitness equipment, and reduces maintenance costs. Furthermore, the anti-slip protrusions 121 inside the cable groove 12 can improve the clamping degree of the pull rope in the pull rope clamping space, further reducing the risk of the pull rope detaching from the pull rope clamping space, and helping to ensure the working stability of the pull rope connector.

[0035] Furthermore, the number of the anti-slip protrusions 121 is multiple.

[0036] As can be seen from the above description, the multiple anti-slip protrusions 121 inside the cable groove 12 can better improve the fixing effect of the cable clamping space on the cable.

[0037] Furthermore, the groove 12 includes a main portion 122 in the shape of a ring frame.

[0038] As can be seen from the above description, the long path of the groove 12 allows the rope clamping space to better fix the rope.

[0039] Furthermore, the cable groove 12 also includes a rope end storage part 123 connected to the main part 122, and the rope end storage part 123 is provided with the anti-slip protrusion 121.

[0040] As described above, the end of the pull rope can be clamped in the rope end storage part 123, which allows the pull rope to be more effectively fixed.

[0041] Furthermore, the main part 122 is connected to the inlet hole 11, and the rope end storage part 123 is located near the connection between the main part 122 and the inlet hole 11.

[0042] As can be seen from the above description, the rope can be wound into several relatively complete loops in the main part 122, so that the space of the main part 122 can be made more fully.

[0043] Furthermore, the main body 2 has a clamping cavity 22, the bottom of the mounting plate 1 is housed in the clamping cavity 22, and the inner bottom surface of the clamping cavity 22 forms the clamping surface 21.

[0044] Furthermore, the mounting plate 1 is connected to the main body 2 by thread, screw, or snap-fit.

[0045] As can be seen from the above description, there are multiple ways to connect the installation disk 1 to the main body 2.

[0046] Furthermore, the mounting plate 1 is also provided with a rubber pad 3.

[0047] As can be seen from the above description, the rubber pad 3 protects the mounting plate 1 while reducing the risk of the mounting plate 1 scratching the user.

[0048] Furthermore, the main body 2 has a hook part 23, and the mounting mechanism includes a hook 41, a first elastic element 42 and a rotating shaft 43. The hook 41 is rotatably connected to the main body 2 through the rotating shaft 43. The hook 41 is used to close the inlet and outlet of the hook part 23. The first elastic element 42 contacts the hook 41 and the main body 2 respectively.

[0049] Furthermore, the main body 2 has a hook portion 23, an installation cavity 24, and a limiting groove 25. The mounting mechanism includes a sliding block 44, a limiting post 45, and a second elastic element 46. The installation cavity 24 is connected to the inlet and outlet of the hook portion 23, and the limiting groove 25 is connected to the installation cavity 24. The sliding block 44 is slidably disposed in the installation cavity 24 and is used to close the inlet and outlet of the hook portion 23. The second elastic element 46 is located in the installation cavity 24 and contacts the sliding block 44 and the main body 2 respectively. One end of the limiting post 45 is connected to the sliding block 44, and the other end of the limiting post 45 passes through the limiting groove 25 and is exposed outside the main body 2.

[0050] Furthermore, the main body 2 has a hook portion 23, and the mounting mechanism includes a sleeve 47 and a third elastic element 48. The sleeve 47 is slidably fitted onto the main body 2. The main body 2 is provided with a guide post 49, and the sleeve 47 is provided with a guide groove 471 that cooperates with the guide post 49. The third elastic element 48 contacts the main body 2 and the sleeve 47 respectively. When the pull rope connector is not subjected to external force, the sleeve 47 blocks the inlet and outlet of the hook portion 23.

[0051] As can be seen from the above description, the specific structure of the mounting mechanism varies and can be set as needed.
