[0035] Example 1

[0036] like Figures 1 to 5 As shown, the brake cable brake device suitable for sports rehabilitation equipment of the present invention includes a brake outer shell 1 for being installed on the sports rehabilitation equipment;

[0037] A brake wire fixing plate 3 for pulling the brake wire is hingedly mounted on the brake outer shell 1;

[0038] The brake outer shell 1 is provided with a rebound shaft 2 which is elastically and slidably connected. The rebound shaft 2 is connected to the brake wire fixing plate 3 via the positioning pin 22 above.

[0039] A guide seat 13 is installed on the brake outer shell 1, and one side of the rebound shaft 2 is slidably installed in the guide seat 13;

[0040] A rebound locking mechanism 4 for locking the rebound shaft 2 for braking is slidably mounted on the brake outer shell 1;

[0041] An unlocking mechanism 5 is mounted on the brake outer shell 1 and is used in conjunction with the locking mechanism.

[0042] The rebound locking mechanism 4 includes a first slider 41 slidably mounted on the brake outer shell 1, a locking pin 42 and a translation member 43 are mounted on the slider, and one end of the locking pin 42 is elastically connected to the brake outer shell 1;

[0043] The brake outer shell 1 is provided with a first slide rail 12 that matches the first slider 41;

[0044] A locking groove 21 is formed on the rebound shaft 2 corresponding to the locking pin 42 .

[0045] The locking pin 42 is aligned with the locking groove 21 on the rebound shaft 2. When the pressure spring 421 of the locking pin 42 is in a released state, the locking pin 42 will push into the locking groove 21.

[0046] One end of the locking pin 42 is sleeved with a pressure spring 421 , and the locking pin 42 is elastically connected to the brake outer shell 1 through the pressure spring 421 .

[0047] The unlocking mechanism 5 includes a second slider 53 slidably mounted on the brake outer shell 1 , a rotatable button shaft 52 is mounted on the second slider 53 , and a lever 51 is provided at the end of the button shaft 52 ;

[0048] The shifting rod 51 is used to shift the translation member 43 to move;

[0049] The translation member 43 is provided with a guide groove 431, and the translation member 43 can be moved when the lever 51 is pulled backward or rotated;

[0050] The brake outer shell 1 is provided with a second slide rail 15 that matches the second slider 53;

[0051] One end of the lever 51 provided on the button shaft 52 abuts against one end surface of the rebound shaft 2 when moving.

[0052] The brake outer shell 1 is provided with a support seat 14 corresponding to the button shaft 52 , and the button shaft is slidably mounted on the support seat 14 .

[0053] A first notch 31 is formed on the brake cable fixing plate 3 , and a second notch 11 is formed on the corresponding brake outer shell 1 . The positioning pin 22 on the rebound shaft 2 fits into the first notch 31 and the second notch 11 .

[0054] One end of the rebound shaft 2 is sleeved with a return spring 23 , and the rebound shaft 2 is elastically connected to the brake outer shell 1 through the return spring 23 .

[0055] The shaft diameter of the rebound shaft 2 where the return spring 23 is mounted is slightly smaller, which facilitates the operation of the return spring 23. At this time, one end of the return spring 23 can be fixed to the rebound shaft 2 by compression. At the same time, a slightly smaller return spring 23 can also be selected and mounted on a slightly smaller diameter part of the rebound shaft, and axial positioning is performed through the outer diameter of the rebound shaft 2.

[0056] Working process or working principle:

[0057] During installation, the brake pad cable should be installed into the slot at the rear of the cable retaining plate 3. First, the cable retaining plate 3 is connected to the rebound shaft 2. As the rebound shaft 2 moves axially, the cable retaining plate 3 rotates around its hinged connection with the brake housing 1, driving the rear cable and pulling the brake pads farther away for braking.

[0058] like Figure 5As shown, in the initial position, the rebound shaft 2 moves toward one end under the elastic force of the return spring 23, and pushes the button shaft 52 toward one end. At this time, due to the overall movement of the rebound shaft 2, the locking pin 42 is located at the outer position of the locking groove 21.

[0059] When braking, the button shaft 52 is pressed down, and the button shaft 52 will move toward the other end against the rebound shaft 2, driving the brake wire fixing plate 3 to pull the brake wire to achieve braking. When the locking groove 21 on the rebound shaft 2 is aligned with the locking pin 42, the locking pin 42 will drill into the locking groove 21 of the rebound shaft 2, preventing the rebound shaft 2 from rebounding, thereby fixing the brake wire fixing plate 3 connected to it, keeping the brake wire in a taut state, and achieving continuous braking. At the same time, the translation member 43 moves to the locked position with the locking pin 42, and the lever 51 enters one end of the guide groove 431 on the translation member 43, as shown in FIG. Figure 3 shown.

[0060] To release the brake, the button shaft 52 must be rotated. This activates the lever 51, pushing the translating member 43 to the right. The locking pin 42 is simultaneously pushed sideways, exiting the locking slot 21 of the rebound shaft 2. The rebound shaft 2, acting under the force of the return spring 23, rebounds, simultaneously rotating the brake cable retaining plate 3 along the hinge axis. This releases the brake cable, causing the brake pad, connected to the brake cable at its distal end, to move in the opposite direction, releasing the brake and achieving a reset.

[0061] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
