Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulators, in particular to a pressure regulating component for a spraying machine. Background Art

[0002] The pressure regulator of the sprayer is a device used to adjust the pressure during the paint spraying process. It can adjust the gas or liquid pressure required by the paint spray gun to control the flow rate and spraying effect of the paint. The pressure regulator has the following functions in the spraying process: Control the spraying pressure: By adjusting the pressure, the flow rate and spray effect of the paint during the spraying process can be controlled. The appropriate spraying pressure can ensure that the paint is sprayed evenly and stably, avoiding the problem of excessive or insufficient spraying. Protect the spraying equipment: The appropriate spraying pressure can reduce the wear and failure risk of the equipment. Too high pressure may cause damage to the spraying equipment, while too low pressure may not achieve the ideal spraying effect. Save paint: By adjusting the spraying pressure, the flow rate of the paint can be controlled to achieve the purpose of saving paint. The appropriate spraying pressure can reduce sputtering and waste during the spraying process.

[0003] However, there are some shortcomings in the current sprayer pressure regulator: when it is installed outside for use, its outer surface has no protective device and is easily damaged by moisture erosion and external physical collisions. Therefore, some pressure regulators will be installed with a protective shell on the outer surface, but it is inconvenient to operate the internal pressure regulator after the protective shell is installed. When the staff needs to adjust, they need to open the baffle on the outer shell before operating, which is very inconvenient. Utility Model Content

[0004] The utility model aims to provide a pressure regulating component for a spraying machine to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure regulating component of a sprayer, comprising an outer shell and a clamping device body, a sleeve rod is rotatably installed at the inner top end of the outer shell, an inner rod is inserted into the bottom end of the sleeve rod, the bottom end of the inner rod is connected to the clamping device body, a pressure regulator is fixed inside the clamping device body, and the pressure regulator is arranged at the inner bottom end of the outer shell, a sleeve is provided inside the clamping device body, a shaft rod is rotatably installed in the middle of the sleeve, shaft sleeves are sleeved on the two end surfaces of the shaft rod, and a clamping block is fixed on the outer surface of the sleeve.

[0006] When using a spray machine pressure control component in the present technical solution, the staff puts the outer shell on the surface of the pressure regulator. After putting it on, the staff turns to open the baffle. After the baffle is turned and opened, the staff pulls the clamping device body and puts it on the knob of the pressure regulator. After putting it on, the staff pinches the second turning handle with fingers and applies force to turn it. The rotational force applied to the second turning handle will be synchronized to the shaft rod. The shaft rod rotates and uses the threads on the two end surfaces to engage the threads on the inner surfaces of the two sleeves. The engagement of the threads will cause the two sleeves to move in opposite directions on the two end surfaces of the shaft rod, and the two sleeves moving in opposite directions will move together with the clamping blocks fixed on the outer surfaces. The two clamps The opposite movement of the blocks will shorten the distance between them, and the knob inserted between them will be clamped and fixed. After the knob is clamped and fixed, the shell can be firmly installed on the surface of the pressure regulator. Finally, the staff turns the closing baffle. When it is necessary to control and adjust the pressure regulator, the staff can directly hold the first turning handle and apply a rotational force without opening the baffle. The rotational force applied to the first turning handle will be synchronized to the sleeve rod, and the sleeve rod will rotate with the inner rod inserted inside, and the inner rod will rotate with the clamping device body fixed at one end, and the clamping device body will rotate with the knob clamped inside, so that the internal pressure regulator can be indirectly controlled outside the shell.

[0007] Preferably, a slide rod is fixed on both sides of the inner part of the jacket, a slide sleeve is sleeved on both end surfaces of the slide rod, and a clamp block is fixed on the outer surface of the slide sleeve. Through the cooperation between the slide rod and the slide sleeve, the two ends of the shaft rod are limited when the shaft rod is threadedly engaged with the shaft sleeve and indirectly moves the clamp block, so as to achieve the effect of stabilizing the movement of the clamp block in the jacket.

[0008] Preferably, a second handle is fixed to one end of the shaft, and the second handle is arranged on one side of the outer side of the jacket. The installation of the second handle makes it convenient for the staff to apply a rotational force to the shaft, and provides a force application point.

[0009] Preferably, the bottom interior of the sleeve rod and the exterior of the inner rod are both designed with a hexagonal structure. The hexagonal structure design enables the sleeve rod to rotate with the inner rod when rotating, and the inner rod can move up and down inside the sleeve rod.

[0010] Preferably, a first rotating handle is fixed to the top of the sleeve rod, and the first rotating handle is arranged at the top of the outer shell. The installation of the first rotating handle makes it convenient for the staff to apply a rotating force to the sleeve rod, and provides a force application point.

[0011] Preferably, the outer sides of the housing are provided with bayonet holes, and the inner surfaces of the bayonet holes are fixed with rubber pads. Through the cooperation between the bayonet holes and the rubber pads, the pipes connected to the two ends of the pressure regulator can be inserted into the inner parts thereof, thereby achieving the effect of providing a location for insertion and avoiding wear due to direct contact.

[0012] Preferably, a baffle is rotatably mounted on the outer front surface of the housing, and a visual window is embedded in the middle of the baffle. The installation of the baffle allows the staff to rotate and open this place for operation, so that after the housing is sleeved on the surface of the pressure regulator, the housing can be rotated and opened here to operate to connect the clamping device body with the control knob on the pressure regulator, and the installation of the visual window allows the staff to see the internal situation outside the housing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses a shell to wrap the pressure regulator to protect it, prevent it from being damaged by wind, rain, sun and the like, and also reduce damage caused by physical collisions and the like. A clamping device body that can be adjusted up and down is provided in the shell, which can adapt to pressure regulators of different sizes and clamp their control knobs, so that it is convenient for the staff to control and operate the pressure regulator outside the shell.
