[0006] Preferred technical solution 1: A mounting groove is provided on the half-cover below the front end of the arc-shaped groove, the elastic barrier is arranged in the mounting groove and the top end slides through the top wall of the mounting groove and extends into the arc-shaped groove. When the two groups of half-covers are docked, the insert on one group of half-covers is inserted into the mounting groove on the other group of half-covers to push the elastic barrier to cause elastic deformation and move out from the bottom of the arc-shaped groove.
[0007] Preferred technical solution two: the elastic barrier member includes a rectangular frame that slides through the top wall of the mounting groove, and a spring 2 is connected between the rectangular frame and the bottom wall of the mounting groove. The bottom side of the insert is an inclined surface. After the insert is inserted into the mounting groove, it is inserted into the inner hole of the rectangular frame. As the insert moves inward, the inclined surface on the bottom side pushes the rectangular frame to gradually move downward.
[0008] Optimal technical solution three: the arc groove 1 and the arc groove 2 are distributed on the upper and lower end surfaces of the half cover.

[0012] 1. The arrangement of the arc groove 1, the arc groove 2, the arc hooking piece, the elastic barrier piece and the inserting piece can automatically sense the docking state of the two sets of half covers. When the docking is completed, the inserting piece on one set of half covers contacts and deforms with the elastic barrier piece on the other set of half covers to release the blocking state of the arc hooking piece, so that the arc hooking piece slides into the arc groove 2 on the other set of half covers under the push of the spring 1, and the self-sensing preliminary hooking of the two sets of half covers is completed in a short time, which greatly reduces the force application time during assembly;
[0013] 2. The greater the working load of the coupling, the more heat it generates, causing the heat expansion material layer on the inner wall of the arc groove 1 and the arc groove 2 to absorb heat and expand, further clamping the arc-shaped hooking piece, thereby improving the docking stability of the two sets of half covers.

When the two groups of half covers 1 are butt-jointed, the arc groove 11 and the arc groove 2 12 on one group of half covers 1 are respectively butt-jointed and connected with the arc groove 2 12 and the arc groove 11 on the other group of half covers 1, and a spring 13 is connected between the rear end of the arc hooking member 2 and the inner end of the arc groove 11, and the spring 13 is an arc spring, and an elastic spring is provided at the front end of the arc groove 11 The barrier member 4 is provided with a mounting groove 14 below the front end of the arc groove 11 on the half cover 1. The elastic barrier member 4 is arranged in the mounting groove 14 and the top end slides through the top wall of the mounting groove 14 and extends into the arc groove 11 to block the front end of the arc-shaped hooking member 2. At the same time, an inserting member 5 is arranged at the front end of the arc groove 2 12. When the two groups of half covers 1 are docked, the inserting member 5 on one group of half covers 1 is inserted into the mounting groove 14 on the other group of half covers 1 to push the elastic barrier member 4 to undergo elastic deformation and move down from the arc groove 11, thereby releasing the blocking state of the arc-shaped hooking member 2, so that the arc-shaped hooking member 2 slides into the arc groove 2 12 on the other group of half covers 1 under the push of the spring 1 3, completing the self-inductive preliminary connection of the two groups of half covers 1.
[0023] See also Figure 3, serpentine spring coupling cover, the elastic baffle 4 includes a rectangular frame 41 that slides through the top wall of the mounting groove 14, and a spring 2 42 is connected between the rectangular frame 41 and the bottom wall of the mounting groove 14. The elastic connection between the rectangular frame 41 and the mounting groove 14 is realized by the setting of the spring 2 42. Under the push of the spring 2 42, the middle and upper part of the rectangular frame 41 enters the arc groove 11, and the middle and lower part of the rectangular frame 41 is located in the mounting groove 14. The bottom side of the insert 5 is an inclined surface. After the insert 5 is inserted into the mounting groove 14, the front end is inserted into the rectangular frame 41. As the insert 5 moves inward, the inclined surface of the bottom side pushes the rectangular frame 41 to gradually move downward until the rectangular frame 41 is out of contact with the front end of the arc hooking member 2.

[0024] A magnet is provided at the rear side of the arc-shaped groove 11. When disassembling, the arc-shaped hooking member 2 is pushed back to compress the spring 2 3 until the ferromagnetic part embedded at the rear end of the arc-shaped hooking member 2 is attracted by the magnet. At this time, the bolts can be removed to separate the two groups of half covers 1. After separation, the arc-shaped hooking member 2 is pushed forward again to keep the ferromagnetic part away from the magnet until the front end of the arc-shaped hooking member 2 contacts the extended rectangular frame 41 again to block it.

Since the serpentine spring sheets will produce elastic deformation when subjected to force, a certain amount of heat will be generated. At this time, the heat is absorbed by the heat expansion material layer 13 to expand and increase the friction resistance with the arc-shaped hooking part 2, so as to avoid the arc-shaped hooking part 2 from shaking during working vibration, and the connection force of the arc-shaped hooking part 2 is increased to reduce the force on the bolts, so as to avoid the bolts from loosening or deformation under force, thereby extending the service life.
