Detailed Implementation

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See Figures 1-5 The present invention provides a technical solution:

[0027] A button-type quick-release mechanism includes a quick-release retaining ring 1, a retaining plate 2, a quick-release mounting ring 3, a sliding block 4, a locking pin 5, a locking spring 6, an adjusting post 7, a pressing head 8, and an unlocking plate 9. One end of the quick-release retaining ring 1 is fixedly mounted on the retaining plate 2. The retaining plate 2 is provided with a guide groove 10, and sliding blocks 4 are slidably mounted on both ends of the guide groove 10. A locking pin 5 is fixedly mounted on one end of each sliding block 4. A first insert that cooperates with the locking pin 5 is provided on the side wall of the quick-release retaining ring 1. Hole 11, quick-release mounting ring 3 is sleeved on quick-release fixing ring 1 and a second insertion hole 12 is provided on the side wall to cooperate with locking pin 5. A button hole 13 is provided on the side wall of quick-release fixing ring 1 to cooperate with pressing head 8. Two unlocking plates 9 are fixedly provided on the end of pressing head 8, which respectively cooperate with adjusting post 7. The two unlocking plates 9 are arranged in a V shape. The two adjusting posts 7 are arranged between the two unlocking plates 9. A limiting pressure plate 14 is fixedly provided on one end of quick-release fixing ring 1 to prevent unlocking plate 9 from disengaging. The quick-release fixing ring 1 and the fixing plate 2 are integrally formed. The quick-release fixing ring 1 connects to the equipment on one side, and the quick-release mounting ring 3 connects to the equipment on the other side. The sliding block 4 does not fall off in the guide groove 10. Under the action of the locking spring 6, the two sliding blocks 4 are pushed to both sides. The locking pins 5 on the two moving blocks 4 pass through the first insertion hole 11 and are inserted into the second insertion hole 12. At this time, the quick-release fixing ring 1 and the quick-release mounting ring 3 can be fixed together. When the pressing head 8 is manually pressed towards the guide groove 10, the two unlocking plates 9 on the pressing head 8 move towards the guide groove 10. The two unlocking plates 9 press on the adjusting column 7. Under the action of the adjusting column 7, the two sliding blocks 4 move closer. At this time, the locking pins 5 disengage from the second insertion hole 12, but do not disengage from the first insertion hole 11. At this time, the quick-release fixing ring 1 and the quick-release mounting ring 3 can be separated. The limiting pressure plate 14 is fixed to the quick-release fixing ring 1 by screws. The limiting pressure plate 14 and the unlocking plate 9 are fitted with a clearance. The two sliding blocks 4 on the guide groove 10 are arranged symmetrically.

[0028] In some embodiments, a spring sleeve 15 is fixedly provided on the sliding block 4, and the two ends of the locking spring 6 are respectively disposed in the two spring sleeves 15. The spring sleeves 15 serve two purposes: first, to position the two ends of the locking spring 6; and second, to limit the sliding of the sliding block 4, so that when the two spring sleeves 15 are in contact, the locking pins 5 on the two sliding blocks 4 will not disengage from the two first insertion holes 11.

[0029] In some embodiments, the locking spring 6 is sleeved on the positioning rod 16, and the two ends of the positioning rod 16 are respectively disposed in two spring sleeves 15. Under the action of the two unlocking plates 9, the adjusting post 7 on the sliding block 4 is subjected to a force away from the pressing head 8. In order to prevent the sliding block 4 from disengaging from the guide groove 10, the positioning rod 16 is provided to counteract the force applied to the adjusting post 7 by the unlocking plate 9.

[0030] In some embodiments, a bearing 17 is sleeved on the adjusting column 7, and the bearing 17 cooperates with the unlocking plate 9. The bearing 17 is a deep groove ball bearing in the prior art. The bearing 17 on the adjusting column 7 changes the sliding friction between the adjusting column 7 and the unlocking plate 9 into rolling friction, so that the sliding block 4 can be more easily controlled by the unlocking plate 9.

[0031] In some embodiments, the adjusting column 7 is provided with a pressure ring 18 to prevent the bearing 17 from falling off. The bearing 17 and the adjusting column 7 are fitted with a clearance fit. To prevent the bearing 17 from falling off the adjusting column 7, the pressure ring 18 presses against the inner ring of the bearing 17. The pressure ring 18 is fixed to the adjusting column 7 by screws.

[0032] In some embodiments, a limiting rod 19 is fixedly provided on the fixed plate 2, and a limiting step 20 that cooperates with the limiting rod 19 is provided on the unlocking plate 9. The pressing head 8 is T-shaped, and the two unlocking plates 9 on the pressing head 8 are symmetrically arranged. Two limiting protrusions 21 are fixedly provided on the fixed plate 2, and the pressing head 8 is disposed between the two limiting protrusions 21. The limiting rod 19 and the limiting step 20 cooperate to limit the movement distance of the pressing head 8, preventing the pressing head 8 from entering the quick-release fixing ring 1 and not coming out. The function of the limiting protrusions 21 is to guide the movement of the pressing head 8 and prevent the two unlocking plates 9 from tilting to one side at the same time, which could easily cause one locking pin 5 to disengage from the second insertion hole 12 while the other locking pin 5 is still inserted into the second insertion hole 12.

[0033] In some embodiments, a positioning groove 22 is provided on the outer wall of the quick-release retaining ring 1, and a positioning strip 23 that mates with the positioning groove 22 is provided on the inner wall of the quick-release mounting ring 3. A first insertion hole 11 is provided on the positioning groove 22, and a second insertion hole 12 is provided on the positioning strip 23. The positioning groove 22 and the positioning strip 23 facilitate the assembly and disassembly of the quick-release retaining ring 1 and the quick-release mounting ring 3, while preventing relative rotation between them.
