DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-4 As shown, the utility model provides a quick-detachable chain sleeve, including an outer link plate 1, which is provided with two front and rear outer link plates 1, and two inner link plates 2 are provided on the inner sides of the two outer link plates 1, and through holes 1 3 are provided on the left and right sides of the outer link plate 1, and through holes 2 4 are provided on the left and right sides of the inner link plate 2, and shaft pins 5 are provided inside the through holes 1 3 and 2 4, and the outer side of the shaft pin 5 is sleeved with a limiting sleeve 6, and the left and right ends of the shaft pin 5 are fixedly provided with screws 7, and the outer side of the screw 7 is sleeved with a cap 8, and the outer side of the cap 8 is provided with a slot 9, and a fixing frame 10 is fixedly provided on the outer side of the outer link plate 1, and a sliding frame 13 is provided inside the fixing frame 10, and a pull plate 15 is provided on the outer side of the sliding frame 13, and a connecting rod 16 is fixedly provided on the inner side of the pull plate 15, and a clamping block 18 is fixedly provided on the other end of the connecting rod 16, and a spring 17 is sleeved on the outer side of the connecting rod 16.

[0031] Specifically, the limiting sleeve 6 is arranged between the inner link plates 2 at the front and rear sides. The advantage is that the setting of the limiting sleeve 6 can play a role in limiting the inner link plates 2 at the front and rear sides.

[0032] Specifically, a thread is provided on the side wall inside the cap 8. The advantage is that the thread arrangement on the cap 8 facilitates the cap 8 to be screwed onto the screw rod 7, thereby limiting the front and rear sides of the outer link plate 1.

[0033] Specifically, one end of the spring 17 is fixedly arranged on the outside of the sliding frame 13, and the other end of the spring 17 is fixedly arranged on the outside of the block 18. The advantage is that the rebound force of the spring 17 can act on the block 18, so that the block 18 can move inward.

[0034] Specifically, the block 18 matches the slot 9, and the block 18 is engaged inside the slot 9. The advantage is that the block 18 is engaged inside the slot 9, so that the block 18 can resist the cap 8 to prevent it from loosening, thereby ensuring the stability of the chain.

[0035] Embodiment 2:

[0036] like Figure 4 As shown, as an improvement to the previous embodiment, specifically, a slide groove 11 is provided inside the fixed frame 10, and the sliding frame 13 is arranged inside the slide groove 11. The advantage is that the opening of the slide groove 11 facilitates the arrangement of the sliding frame 13, so that the sliding frame 13 can slide back and forth inside the slide groove 11.

[0037] Specifically, a limiting groove 12 is provided on the outer side of the inner part of the slide groove 11, and a limiting block 14 is provided inside the limiting groove 12, and the limiting block 14 is fixedly provided on the outer side of the sliding frame 13. The advantage is that the limiting groove 12 can limit the limiting block 14, and the limiting block 14 can further limit the sliding frame 13 to prevent it from sliding down from the fixed frame 10.

[0038] When in use, when it is necessary to install the outer link plate 1 and the inner link plate 2, the personnel sequentially pass the shaft pin 5 through the through hole 1 3 on the front outer link plate 1, the through hole 2 4 on the front inner link plate 2, the limiting sleeve 6, the through hole 2 4 on the rear inner link plate 2 and the through hole 1 3 on the rear outer link plate 1, and then the cap 8 can be screwed on the screw 7. At this time, the cap 8 can cooperate with the limiting sleeve 6 to complete the installation between the outer link plate 1 and the inner link plate 2, and then the personnel pull the pull plate 15 on this side to the outside, and the pull plate 15 drives the block 18 to the outside through the connecting rod 16. The spring 17 is compressed, and the sliding frame 13 is pulled to drive the block 18 to move to the outside of the cap 8. The pull plate 15 is released, and the block 18 is acted upon by the rebound force of the spring 17 so as to move inward, so that the block 18 can be engaged into the inside of the slot 9, and then can resist the cap 8, preventing the cap 8 from loosening due to vibration, thereby ensuring the stability of the chain; when disassembly is required, the personnel only need to take out the block 18 from the inside of the slot 9, unscrew the cap 8 from the screw 7, and take out the axle pin 5 to complete the disassembly.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
