[0027] In order to better understand the purpose, function and specific design of the present utility model, the connecting device of the present utility model applied to fitness accessories will be further described in detail below with reference to the accompanying drawings.

[0028] As Figures 1 - 9As shown in the figure, the connecting device of the present utility model applied to fitness accessories includes a card seat 1 and a connecting head 2. One end of the card seat 1 is a fixed end, and the fixed end is connected to a pulling rope 3, and the pulling rope 3 is connected to a fitness equipment; the other end of the card seat 1 is a connecting end, and the connecting end is provided with a connected clamping channel 11 and a clamping cavity 12. The clamping channel 11 is arranged on the top wall of the card seat 1, and the clamping cavity 12 is arranged inside the card seat 1; one end of the connecting head 2 is provided with a clamping portion 21 whose shape matches that of the clamping channel 11. The connecting head 2 is connected to a fitness accessory. The clamping portion 21 of the connecting head 2 is inserted into the clamping cavity 12 through the clamping channel 11, and the clamping portion 21 can be clamped with the clamping cavity 12 by rotation to realize the connection between the fitness accessory and the fitness equipment; a button 4 is arranged on the side wall of the card seat 1, and the button 4 can limit the movement range of the clamping portion 21 in the clamping cavity 12, thereby restricting the rotation angle of the clamping portion 21 to realize the locking or unlocking of the connecting head 2.

[0029] Specifically, as Figures 1 - 2 shown, the clamping channel 11 of this embodiment is strip-shaped. Correspondingly, the clamping portion 21 of the connecting head 22 is T-shaped. The cross beam of the T-shaped can be inserted into the clamping cavity 12 through the clamping channel 11, and then the connecting head 2 is rotated, so that the cross beam of the T-shaped can be clamped with the top wall of the clamping cavity 12 and cannot be pulled out. Only when the length direction of the cross beam of the T-shaped is consistent with the length direction of the clamping channel 11, the connecting head 2 can be pulled out through the clamping channel 11, so as to realize the disassembly of the fitness accessory and the fitness equipment.

[0030] As Figures 3 - 6 shown, a button channel 13 is opened on the side wall of the card seat 1. The button 4 is inserted into the button channel 13 and can slide in the button channel 13. Pressing the button 4 inward can expand the movement range of the clamping portion 21 in the clamping cavity 12, so that the cross beam of the clamping portion 21 of the connecting head 2 can be inserted into the clamping cavity 12 or pulled out from the clamping cavity 12 to realize the connection or disassembly of the fitness accessory and the fitness equipment. It should be noted that an elastic component 5 is arranged in the button channel 13. The elastic component 5 can provide a restoring force for the button 4 and keep the button 4 in the initial position to keep the movement range of the clamping portion 21 in the clamping cavity 12 in the smallest state, so as to ensure that the connecting head 2 and the card seat 1 are in a locked state and avoid the connecting head 2 and the card seat 1 falling off during use. The elastic component 5 is a spring.

[0031] The button 4 is columnar, and a limiting groove 41 is arranged on the side wall of the button 4. The limiting groove 41 corresponds to the clamping cavity 12. The movement of the button 4 can change the spatial shape in the clamping cavity 12, thereby changing the movement range of the clamping portion 21 in the clamping cavity 12.

[0032] To prevent the button 4 from disengaging from the card holder 1, a button chute 42 is provided on the side wall of the button 4 in this embodiment. A set screw 6 is provided in the card holder 1. The set screw 6 is inserted into the button chute 42 and can slide relative to the button chute 42. When the button 4 is pressed, the set screw 6 slides along the button chute 42, thereby restricting the forward and backward movement of the button 4 within a reasonable range and preventing it from disengaging from the card holder 1. Preferably, to improve the stability of the movement of the button 4 and the reliability of anti-disengagement, a button chute 42 is symmetrically provided on each side of the button 4. Correspondingly, two set screws 6 are provided in the card holder 1, and the two set screws 6 are respectively inserted into a button chute 42.

[0033] It should be noted that, as Figure 7 shown, to facilitate the installation of the button 4, an installation hole 14 is provided on the side wall of the card holder 1. The installation hole 14 is communicated with the button channel 13 and corresponds to the button chute 42 on the button 4 to facilitate the connection between the set screw 6 and the button chute 42 of the limit post.

[0034] Preferably, to improve the impact resistance of the card holder 11, a buffer layer is provided on the outer surface of the card holder 11. The buffer layer can be a rubber sleeve or a silica gel sleeve, etc.

[0035] A connection hole 22 is further provided on the connector 2 in this embodiment. The fitness accessory can be connected to the connector 2 through the connection hole 22. When it is necessary to connect the fitness accessory to the fitness equipment, press the button 4 to expand the activity range of the clamping portion 21 in the clamping cavity 12. Then insert the clamping portion 21 of the connector 2 into the clamping cavity 12 through the clamping channel 11 and rotate it by 90 degrees. Release the button 4, and the limit groove 41 moves and reduces the activity range of the clamping portion 21 in the clamping cavity 12, thereby restricting the rotation angle of the clamping portion 21 to complete the locking of the connector 2, so as to realize the connection between the fitness accessory and the fitness equipment. When it is necessary to disassemble the fitness accessory, press the button 4 to make the limit groove 41 move and expand the activity range of the clamping portion 21 in the clamping cavity 12. Then rotate the connector 2 to make the length direction of the cross beam of the clamping portion 21 consistent with the length direction of the clamping channel 11. Then pull out the clamping portion 21 from the clamping channel 11 to realize the disassembly of the fitness accessory from the fitness equipment.

[0036] As Figures 8 - 9As shown in the figure, for the convenience of connecting the pulling rope 3, the fixed end of the card seat 1 is detachably connected with a pulling rope fixing seat 7. The pulling rope fixing seat 7 is provided with a pulling rope limiting hole 71 and a pulling rope through hole 72 which are communicated with each other. The end of the pulling rope 3 is spherical, and the spherical end of the pulling rope 3 can be limited in the pulling rope limiting hole 71. The pulling rope 3 can pass through the pulling rope through hole 72 and be connected with the fitness equipment to realize the installation of the pulling rope 3. In this embodiment, the fixed end of the card seat 1 is provided with a threaded hole. Correspondingly, the outer surface of the pulling rope fixing seat 7 is provided with an external thread, and the pulling rope fixing seat 7 is threadedly connected with the fixed end of the card seat 1. Preferably, an installation groove is provided on the end face of the pulling rope fixing seat 7 near the pulling rope through hole 72 to facilitate the twisting of the pulling rope fixing seat 7 by tools such as a wrench.

[0037] The connecting device of the present utility model applied to fitness accessories has a simple structure, ingenious design, convenient assembly and reliable connection. When connecting with fitness accessories, only need to press the button 4, then insert the connecting head 2 into the clamping channel 11 and rotate it by 90 degrees, and then release the button 4 to complete the connection. When it is necessary to disassemble the fitness accessories, only need to press the button 4, and then rotate the connecting head 2 by 90 degrees to pull out the connecting head 2 from the clamping channel 11 to complete the disassembly. The operation is simple, time-saving and labor-saving, greatly improving the user's fitness experience.
