DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0023] Refer to the drawings Figures 1-7An external insertion type plum blossom coupling includes a first claw plate 1, a plum blossom pad 2, and a second claw plate 3. The first claw plate 1 has a mounting plate 11 on one side, the diameter of which is larger than that of the first claw plate 1. The mounting plate 11 has a first protruding claw 12 circumferentially on the side opposite to the first claw plate 1. First mounting grooves 13 are formed on both sides of the first protruding claw 12, located opposite to the outer edge of the outer wall extension line of the first claw plate 1. The plum blossom pad 2 includes several detachable connecting parts 21, each with a pad 22 for transmitting torque and damping vibration during coupling operation. The outer wall of the second claw plate 3 has a second protruding claw 31 circumferentially to correspond to the gap between adjacent first protruding claws 12. Second mounting grooves 32 are formed on both sides of the second protruding claw 31 to correspond to the first mounting grooves 13 and form a pressure-reducing groove for inserting the pad 22. The pressure-reducing groove is located opposite to the outer edge of the outer wall extension line of the first and second claw plates 3, facilitating the insertion and removal of the pad 22 from the plum blossom pad 2.

[0024] After installing the first claw plate 1 and the second claw plate 3 into place, insert the pad 22 of the plum blossom pad 2 into the pressure relief groove formed by the first mounting groove 13 and the second mounting groove 32 to facilitate the quick installation of the plum blossom pad 2. When the pad 22 needs to be replaced due to wear after long-term use, pull the connector 21 to pull the pad 22 out of the pressure relief groove, and then replace it with a new plum blossom pad 2. The entire replacement process does not require disassembling the first claw plate 1 and the second claw plate 3. Disassembly is simple and convenient, which greatly improves the efficiency of disassembly and replacement.

[0025] In this embodiment, a connecting block 23 is provided between adjacent connectors 21. The connecting block 23 has slots 24 on both sides for inserting the ends of the connectors 21, which facilitates connecting several connectors 21 into a whole. When disassembling, the connecting block 23 can be removed to make each connector 21 relatively independent, thereby facilitating the replacement and disassembly of each connector 21. This allows for partial replacement of the plum blossom pad 2, reducing the replacement cost.

[0026] In this embodiment, the slot 24 passes through the side of the connecting block 23 facing the center of the plum blossom pad 2, so that the connecting block 23 is inserted relative to the side of the plum blossom pad 2 away from the center of the connecting member 21. By pulling the connecting block 23 outward, the connecting block 23 can be quickly separated from the connecting member 21, that is, the connecting member 21 can be quickly formed into a relatively independent individual, thus speeding up the replacement efficiency.

[0027] In this embodiment, the connector 21 has a groove 25 for inserting fingers on the side facing the pad 22, which greatly improves the ease of disassembling the plum blossom pad 2.

[0028] In this embodiment, the mounting plate 11 has an insertion slot 14 at the position corresponding to the first mounting slot 13 for the insertion of the pad 22. The pad 22 is inserted from the side of the first claw plate 1. After passing through the insertion slot 14, the pad 22 enters the pressure relief slot. The pad 22 is adapted to the inside of the insertion slot 14, so that the plum blossom pad 2 is fixed relative to the first claw plate 1, avoiding the plum blossom pad 2 from falling off during use and affecting the operation of the coupling.
