Description
Technical Field
[0001] The utility model relates to the technical field of paint spraying machines, and more specifically to a building decoration spraying processing device. Background Art
[0002] The sprayer is a special coating equipment that uses spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make a stable and continuous reciprocating motion.
[0003] When the paint sprayer is working, the operator needs to hold the spray gun to spray the wall. When holding, the tiger's mouth and thumb are attached to one side of the spray gun, and the other four fingers are pressed on the trigger. During the spraying process, the high-pressure gas carrying the paint will have a great reaction force. The reaction force will exert force on the palm through the spray gun and reduce the pressure of the operator's other four fingers on the spray trigger, which is not conducive to the stable spraying of architectural decoration. In view of this, we propose a spraying device for architectural decoration. Utility Model Content
[0004] The utility model aims to overcome the shortcomings of the prior art, meet the actual needs, and provide a building decoration spraying processing device to solve the technical problem that the reaction force of the current paint spraying machine affects the uniform spraying of the spray gun.
[0005] To solve the above technical problems, the utility model provides the following technical solutions: a building decoration spraying processing device, comprising a spray gun, the outer side of the spray gun is movably connected with a trigger, a push plate is provided in the middle of the spray gun, one side of the push plate is provided with a movable groove, one end of the push plate is fixedly connected with a push rod, one side of the push rod is fixedly connected with a sliding block, one end of the push rod is fixedly connected with a connecting shaft, the outer surface of the connecting shaft is movably connected with a rotating rod, the middle part of the rotating rod is movably connected with a fixed shaft fixed to the outer surface of the spray gun, one end of the rotating rod is fixedly connected with a push rod, and one end of the push rod is movably connected with a pull rod.
[0006] The utility model holds the spray gun, with the thumb and other four fingers respectively staying on the surface away from the spray gun and the trigger, and the thumb is fitted in the finger groove. During the paint spraying operation, the reaction force generated by the high-pressure gas driving the paint liquid to spray drives the spray gun and the trigger to move backward as a whole. The thumb pushes the push plate to move forward and drives the rotating rod to rotate on the outer surface of the fixed axis through the push rod. The rotating rod and the push rod further apply a force to the pull rod to press the trigger in the same direction as the other four fingers, and the impact force is partially converted into the pulling force of the pull rod on the trigger, so that the pressing force of the other four fingers on the trigger is increased when the spray gun and the thumb are subjected to the reaction force, and the stability of the paint spraying machine is maintained.
[0007] Preferably, a return spring is fixedly connected to one side of the sliding block, and a finger groove is provided on the front surface of the push plate.
[0008] Preferably, a semicircular protrusion is provided at one end of the inner wall of the pull rod, which fits the outer surface of the trigger; so that when the pull rod changes its angle under the pulling of the rotating rod, the protrusion can maintain good contact with the outer surface of the trigger, thereby facilitating the application of force to the trigger.
[0009] Preferably, a limiting block is provided on the edge of the slider, and a placement groove for matching the slider and the return spring is opened on the outer wall of the spray gun; the limiting block maintains the connection between the push rod and the spray gun, and limits the slider from detaching from the inside of the limiting groove.
[0010] Preferably, a rotation groove matching the rotating rod is formed on an edge of one end of the push rod; the rotation groove is used to provide space for the push rod to push the rotating rod to rotate on the outer surface of the fixed shaft.
[0011] Preferably, the edge of the push plate fits with the outer surface of the spray gun, so that the edge of the spray gun fits with the push plate, which improves the comfort of thumb pressing.
[0012] Preferably, the movable groove is provided on the outer surface of the spray gun corresponding to the push plate and matches with the push plate; the movable groove provides an operating space for the thumb to press the push plate.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model holds the spray gun, with the thumb and other four fingers respectively staying on the surface away from the spray gun and the trigger, and the thumb is fitted in the finger groove. During the spraying operation, the reaction force generated by the high-pressure gas driving the paint liquid to spray drives the spray gun and the trigger to move backward as a whole. The thumb pushes the push plate forward and drives the rotating rod to rotate on the outer surface of the fixed axis through the push rod. The rotating rod and the push rod further apply a force to the pull rod in the same direction as the other four fingers pressing the trigger, and the impact force is partially converted into the pulling force of the pull rod on the trigger, thereby increasing the pressing force of the other four fingers on the trigger under the reaction force of the spray gun and the thumb, and maintaining the stability of the paint spraying machine.
[0015] 2. The utility model also reduces the impact force of the spray gun on the thumb during operation by designing the finger groove and the return spring structure, further solving the problem that the normal operation of the spray gun is affected by excessive impact force.

[0023] like Figures 1 to 5 As shown, the utility model relates to a building decoration spraying processing device, including a spray gun 1, the outer side of the spray gun 1 is movably connected with a trigger 2, a push plate 3 is arranged in the middle of the spray gun 1, one side of the push plate 3 is provided with a movable groove 302, one end of the push plate 3 is fixedly connected with a push rod 4, one side of the push rod 4 is fixedly connected with a slider 5, one end of the push rod 4 is fixedly connected with a connecting shaft 401, the outer surface of the connecting shaft 401 is movably connected with a rotating rod 7, the middle part of the rotating rod 7 is movably connected with a fixed shaft 701 fixed to the outer surface of the spray gun 1, one end of the rotating rod 7 is fixedly connected with a push rod 702, and one end of the push rod 702 is movably connected with a pull rod 8.
[0024] In the embodiment of the utility model, a semicircular protrusion 801 is formed on one end of the inner wall of the pull rod 8 to fit the outer surface of the trigger 2 , and a rotating groove matching the rotating rod 7 is formed on the edge of one end of the push rod 4 .
[0025] In the embodiment of the present invention, the edge of the push plate 3 is in contact with the outer surface of the spray gun 1 , and the moving groove 302 is formed on the outer surface of the spray gun 1 corresponding to the push plate 3 and matches the push plate 3 .
[0026] As another embodiment of the utility model, a return spring 6 is fixedly connected to one side of the slider 5, a finger groove 301 is provided on the front surface of the push plate 3, a limiting block is provided on the edge of the slider 5, and a placement groove matching the slider 5 and the return spring 6 is provided on the outer wall of the spray gun 1.

When holding the spray gun 1, the thumb is pressed into the finger groove 301 on the outer side of the push plate 3, and the other four fingers are pressed on one side of the trigger 2. When the paint is sprayed, the reaction force generated by the high-pressure gas driving the paint liquid to spray out forces the spray gun 1 to move backward. When the upper end of the spray gun 1 tilts backward, the thumb pushes the push plate 3 to move forward and drives the rotating rod 7 to rotate on the outer surface of the fixed shaft 701 through the push rod 4.
