Embodiment 1
[0053] refer to figure 2 , 8 , 9, the connecting device includes an upper splint 1, a lower splint 2, a screw 3 and a nut 4, and the screw 3 passes through the lower splint 2 and the upper splint 1 successively from bottom to top, and then connects with the nut 4; on the upper splint 1 1. The screw 3 between the lower splints 2 also has an elastic ring 5 capable of tightening the screw 3 .
[0054] In order to further fix the connecting device, several protruding anti-slip teeth 6 are also designed on the lower surface of the upper clamping plate 1 and the lower surface of the lower clamping plate 2 .
[0055] The nut 4 includes a nut head 401 wider than the nut body 402 , and a special wrench fitting groove 403 for clamping a special wrench is provided on the upper surface of the nut head 401 . Nut head 401 can be made hexagonal Figure 7 , which will allow the use of a normal wrench during installation.
[0056] The special wrench is transformed from a sleeve, and the c...
Embodiment 2
[0065] On the basis of Example 1, in order to solve the problem that the screw 3 protrudes too much, the cleaning devices such as brushes or scrapers wear abnormally and affect the dust removal effect, the screw 3 is improved as follows.
[0066] A frangible conical tail 304 is added to the tail of the screw body 303 of the screw 3. The main structure of the frangible conical tail 304 is the same as that of the original tail of the screw body 303, but the connection with the screw body 303 is partially bonded. structure, so as to break the easy-fold adhesive part 305 conveniently. Specifically, the easy-fold adhesive part 305 can be bonded to the tail of the screw body 303 in the following ways:
[0067] A. If Figure 5 As shown in a, b, and c, the easy-fold adhesive part 305 is a truncated cone structure, and the lower end surface of the truncated cone structure is bonded to the tail of the screw body 303 .
[0068] B. If Figure 6 As shown in a, b, and c, the easy-fold ad...
Embodiment 3
[0076] If the edge of the device to be connected is flexible, a space for accommodating the screw head 301 and the nut 4 may be reserved. Then, in order to make the screw head 301 and the nut 4 not protrude from the edge surface of the equipment as much as possible, on the basis of embodiment 1 or 2, the upper splint 1 and the lower splint 2 are improved as follows:
[0077] Such as image 3 As shown, a downwardly recessed upper plate concave structure 101 for accommodating the nut 4 is designed on the upper clamping plate 1;
[0078] Such as Figure 4 As shown, an upwardly recessed lower plate concave structure 201 is designed on the lower splint 2 for accommodating the screw head 301 of the nut 4 .
[0079] This enables the connecting device to further reduce the height of the protruding device edge. When other objects need to pass through the connecting device, the adverse effects on it can be reduced.
