Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for wall reconstruction. Background Art

[0002] Real stone paint is a kind of paint with decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors and is used for imitation stone effect on building exterior walls, so it is also called liquid stone. Buildings decorated with real stone paint have natural and real natural color, giving people a sense of elegance, harmony and solemnity. It is suitable for indoor and outdoor decoration of various buildings, so it is widely loved by consumers. When spraying real stone paint, if the distance between the spray gun head and the wall is too close, it is easy to sag. If it is too far, the paint mist is uneven and pitting is easy to appear. If the nozzle is far away from the object surface, the paint mist will fly away on the way, causing waste. The distance between the spray gun head and the wall can usually only be grasped by skilled construction workers by feeling. The spraying effect of unfamiliar construction workers is poor. Moreover, the current spray gun nozzles are fixed, and it is impossible to guarantee that the sprayed paint is uniform.

[0003] In order to solve the above technical problems, the patent document with announcement number CN 213449362 U discloses a real stone paint spraying device for wall reconstruction, including a gun body, a spraying structure is arranged on the gun body, and the spraying structure mainly includes: a connecting sleeve, a driving part and a connecting part, the connecting sleeve is sleeved on the output end of the gun body, the driving part is arranged on the gun body and the connecting sleeve, and the connecting part mainly includes: a side groove, a movable hole, a clamping rod, a spring, a pressing rod, a protective cover and a clamping groove. The utility model adopts a rotating method for spraying, so that the nozzle is evenly distributed, and there will be no pitting. It is also provided with a protective cover, which is convenient for controlling the spraying range.

[0004] Although the prior art uses a protective cover to conveniently control the spraying range, in order to prevent the outer end of the protective cover from scraping or rubbing against the wall surface and damaging the wall or the protective cover, the outer end of the protective cover cannot be attached to the wall, which still requires the operator to control the distance between the outer end of the protective cover and the wall. Utility Model Content

[0005] The utility model mainly provides a spraying device for wall reconstruction, which solves the problem that in order to avoid the outer end of the protective cover from scraping and rubbing on the wall surface to damage the wall or the protective cover, the outer end of the protective cover cannot be attached to the wall, resulting in the operator still needing to control the distance between the outer end of the protective cover and the wall.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A spraying device for wall modification includes a gun body and a protective cover, wherein the outer end of the protective cover is annularly provided with a plurality of mounting holes, a column is slidably connected in the mounting hole, a ball groove is provided in the outer end of the column, and a ball is rotatably arranged in the ball groove; a first elastic member is arranged between the inner end of the column and the mounting hole. With the structure of the present application, the outer end of the protective cover provided with the column and the ball can be directly pressed against the front through the ball, so as to accurately control the distance of the wall surface, and in the process of moving the gun body and the protective cover, the ball rolls on the wall surface, which can effectively avoid the protective cover from scraping and rubbing on the wall surface; at the same time, the setting of the first elastic member can push the column outward and compress it inward in the mounting hole when the wall surface is uneven, so that the column is displaced to match the wall surface, and the ball is pressed against the front surface; and the displacement of the column in the mounting hole through the first elastic member makes the ball pressed against the wall surface, which can effectively form a fence, reduce the degree of paint mist flying outward from the spacing, and reduce waste.

[0008] Furthermore, the protective cover includes a cover body detachably connected to the connecting sleeve, a ring groove is provided at the front end of the cover body, an outer sleeve ring is slidably connected in the ring groove, and a second elastic member is provided between the inner end of the outer sleeve ring and the cover body; a plurality of mounting holes are provided in an annular shape at the outer end of the outer sleeve ring. The protective cover can be detachably connected to the connecting sleeve using any structure. With this structure, the outer sleeve ring can be moved in the ring groove of the cover body, thereby adjusting the distance between the gun body nozzle and the wall.

[0009] Furthermore, the column includes a rod body slidably connected to the mounting hole, and a ferrule detachably connected to the outer end of the rod body, the ferrule and the outer end of the rod body are both provided with ball grooves, the two ball grooves are closed to form the ball groove, and the ferrule is provided with a protruding hole for matching the protrusion of the ball. The ferrule can be threadedly connected to the outer end of the rod body. With this structure, the ferrule and the rod body can be conveniently detachably connected, so that the ball can be well installed in the ball groove.

[0010] Furthermore, a bearing is rotatably connected to the outer ring, a mounting ring is provided on the bearing, an annular cleaning brush is provided on the mounting ring, an electric motor is provided on the cover, an active tooth is provided at the output end of the electric motor, a gear ring meshing with the active tooth is provided on the mounting ring, and the mounting ring is driven by the electric motor to rotate. With this structure, the mounting ring can be driven by the electric motor to rotate with the bearing outside the outer ring, thereby driving the annular cleaning brush to rotate and clean the wall surface, thereby preventing dust from sticking to the wall surface and affecting the adhesion effect of the paint.

[0011] Furthermore, the first elastic member and the second elastic member are both springs, which have a lower cost.

[0012] Beneficial effect: By adopting the structure of the present application, the outer end of the protective cover provided with a column and a ball can be directly pressed against the front through the ball, so as to accurately control the distance to the wall. In the process of moving the gun body and the protective cover, the ball rolls on the wall, which can effectively prevent the protective cover from scraping and rubbing on the wall surface; at the same time, the setting of the first elastic member can push the column outward and compress it inward in the mounting hole when the wall surface is uneven, so that the column is displaced to match the wall surface and the ball is close to the front; and the displacement of the column in the mounting hole through the first elastic member makes the ball press against the wall surface, which can effectively form a barrier, reduce the degree of paint mist flying outward from the spacing, and reduce waste.
