[0028] In order to better understand the purpose, function and specific design of the present utility model, the limit buckle applied to fitness accessories of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Such as Figures 1-10As shown in the figure, the limit buckle applied to fitness accessories of the present utility model includes a card seat 1 and a connection head 2. One end of the card seat 1 is a fixed end, and the fixed end is connected to a pull rope 3, and the pull rope 3 is connected to fitness equipment; the other end of the card seat 1 is a connection end, and a card connection channel 11 is arranged at the connection end. One end of the connection head 2 is provided with a card connection part 21 whose shape matches that of the card connection channel 11. The connection head 2 is connected to the fitness accessory. The card connection part 21 of the connection head 2 can slide linearly in the card connection channel 11 and is inserted into the card connection channel 11 to realize the connection between the fitness accessory and the fitness equipment; a limit post 4 is telescopically arranged on the bottom wall of the card connection channel 11. Correspondingly, a limit hole 22 whose shape matches that of the limit post 4 is arranged on the card connection part 21 of the connection head 2; the limit post 4 is connected to an unlocking button 5, and the unlocking button 5 can drive the limit post 4 to expand and contract to lock or unlock the movement of the card connection part 21 in the card connection channel 11.

[0030] Specifically, as Figures 3-5 shown, the card connection channel 11 of this embodiment is trapezoidal. Correspondingly, the card connection part 21 of the connection head 2 is an inverted trapezoid, so that the connection head 2 can only slide linearly in the card connection channel 11 along the length direction of the card connection channel 11. It can be understood that the card connection channel 11 can also be C-shaped or T-shaped, etc.

[0031] A button channel is opened on the side wall of the card seat 1. The unlocking button 5 is inserted into the button channel and can slide in the button channel. Pressing the unlocking button 5 inward can drive the limit post 4 to contract, so that the card connection part 21 of the connection head 2 can slide freely in the card connection channel 11 to realize the connection or disassembly between the fitness accessory and the fitness equipment. It should be noted that an elastic component 6 is arranged in the button channel. The elastic component 6 can provide a restoring force for the unlocking button 5 and keep the unlocking button 5 in the initial position to keep the limit post 4 in the extended state, so as to ensure that the connection head 2 and the card seat 1 are in a locked state and prevent the connection head 2 and the card seat 1 from falling off during use. The elastic component 6 is a spring.

[0032] As Figures 8-9 shown, the unlocking button 5 is columnar. A locking cavity 51 is vertically arranged on the side wall of the unlocking button 5. The limit post 4 is inserted into the locking cavity 51. A set screw 7 is arranged in the locking cavity 51. A set screw hole is arranged on the limit post 4. The set screw 7 is connected to the limit post 4. The movement of the unlocking button 5 can change the position of the set screw 7 to drive the limit post 4 to expand and contract.

[0033] On the side wall of the locking cavity 51 of this embodiment, a set screw chute 52 is provided. The set screw chute 52 is inclined. The set screw 7 is connected to the limit post 4 and the end of the set screw 7 is accommodated in the set screw chute 52. When pressing the unlocking button 5, the set screw 7 slides along the set screw chute 52, thereby driving the limit post 4 to move; preferably, in order to improve the stability of the limit post 4 during movement, set screw chutes 52 are provided on the side walls on both sides of the locking cavity 51. The middle of the set screw 7 is connected to the limit post 4, and the two ends of the set screw 7 are respectively accommodated in a set screw chute 52. The inclination angle of the set screw chute 52 is 30 - 60 degrees, and this embodiment preferably is 45 degrees.

[0034] It should be noted that, as Figure 1 and 10 shown, an installation hole 12 is provided on the side wall of the card holder 1. The installation hole 12 communicates with the button channel and corresponds to the set screw chute 52 on the unlocking button 5 and the set screw hole on the limit post 4 in the initial position, so as to facilitate the connection of the set screw 7 and the limit post 4.

[0035] Preferably, in order to improve the impact resistance of the card holder 1, a buffer layer is provided on the outer surface of the card holder 1. The buffer layer can be a rubber sleeve or a silicone sleeve, etc.

[0036] A connection hole 23 is further provided on the connector 2 of this embodiment. The fitness accessory can be connected to the connector 2 through the connection hole 23. When it is necessary to connect the fitness accessory to the fitness equipment, press the unlocking button 5 to contract the limit post 4, then insert the connector 2 into the clamping channel 11, and release the unlocking button 5 to make the limit post 4 extend and insert into the limit hole 22 of the clamping part 21 of the connector 2 to lock the connector 2, thereby realizing the connection of the fitness accessory and the fitness equipment; when it is necessary to disassemble the fitness accessory, press the unlocking button 5 to contract the limit post 4, and then move the connector 2 out of the clamping channel 11, then the disassembly of the fitness accessory and the fitness equipment can be realized.

[0037] The limit buckle of the present utility model applied to fitness accessories has a simple structure, ingenious design and convenient assembly. When connecting or disassembling with fitness accessories, only need to press the unlocking button 5, and then insert the connector 2 into the clamping channel 11 or move it out of the clamping channel 11, then the connection or disassembly can be completed. The operation is simple, time-saving and labor-saving, greatly improving the fitness experience of users.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
