[0035] The working principle of the special spraying device for elevator accessories provided by the present utility model is as follows:

[0036] First step: During the use by the staff, the elevator accessories are placed inside the limiting frame 31. The knob 38 is manually rotated to drive the bidirectional threaded lead screw 32 to rotate, so that the driving block 33 slides towards the center. The driving block 33 drives the limiting plate 34 to approach the elevator accessories through the hinged rod 35, fits on the surface of the elevator accessories and limits them, which can firmly clamp the elevator accessories, prevent the elevator accessories from falling during the working process of the device, and enable the spraying work to proceed smoothly.

[0037] Second step: The second motor 43 starts to work, driving the unidirectional threaded lead screw 41 to rotate. The unidirectional threaded lead screw 41 drives the moving block 42 to slide left and right inside the moving groove. The moving block 42 drives the fixing frame 44 to move. The pump starts to work, extracts the paint inside the storage tank 45, and sprays it on the surface of the elevator accessories through the nozzle 46. The first motor 28 starts to work. Through the action of the first sheave 26 and the second sheave 27, the rotating shaft 22 is driven to rotate.

[0038] Third step: During the spraying process, the fan 48 starts to work, making the air flow and pass through the ventilation holes 37, so that the paint sprayed on the surface of the elevator accessories dries quickly. At the same time, the excess paint on the surface of the accessories drips downwards, is collected into the collection box 25 through the diversion plate 24 and the collection port 23, and the excess paint is recycled, effectively solving the problems that the excess paint on the surface of the elevator accessories will drip downwards, easily cause the nozzle 46 to be blocked, greatly increase the maintenance frequency of the staff, and it is not convenient to recycle the excess paint, reducing the practicability of the device.

[0039] Compared with the related technology, the special spraying device for elevator accessories provided by the present utility model has the following beneficial effects:

[0040] Through the coordinated arrangement of the various components of the device, the paint is evenly sprayed on the surface of the fittings, which has the advantages of uniform, comprehensive and rapid spraying. With the assistance of the auxiliary component 20, the excess paint on the surface of the fittings drips downward and is collected inside the collection box 25 through the deflector 24 and the collection port 23, so as to recycle the excess paint. This effectively solves the problem that the excess paint on the surface of the elevator fittings drips downward, which is likely to cause the nozzle 46 to be blocked, greatly increasing the maintenance frequency of the staff, and it is not convenient to recycle the excess paint, thus reducing the practicability of the device.
