Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulators, and specifically relates to a pressure control device for a spraying machine. Background Technique

[0002] A spraying machine is a device used for surface coating. It sprays paint or paint spray evenly on the surface of an object to achieve purposes such as coating, protection, decoration, or others. A spraying machine usually consists of the following components: a spray gun, a paint supply system, a compressed air system, and a control system, etc. Among them, the device used to adjust the pressure of the spraying machine is a pressure regulator.

[0003] A pressure regulator usually consists of the following parts: a main body, a pressure regulating valve, a pressure gauge, and connecting pipes, etc. By adjusting the pressure regulator, an operator can adjust the spraying pressure of the spray gun according to needs to obtain a better spraying effect.

[0004] At present, when a pressure regulator is in use, its outer surface is easily eroded and physically damaged by the external environment. How to protect the pressure regulator to extend its service life is a problem to be solved by the present utility model. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a pressure control device for a spraying machine to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A pressure control device for a spraying machine, including a box body and a shaft rod. A shaft rod is rotatably installed in the middle of one side inside the box body. Shaft sleeves are sleeved on the surfaces of both ends of the shaft rod. A clamping block is fixed on the outer surface of the shaft sleeve. One end of the clamping block clamps a pressure regulator, and the pressure regulator is arranged in the middle inside the box body. A fan is fixed on the other side inside the box body. An air inlet is provided on the side of the fan, and the air inlet is opened at the top end of the outer side of the box body.

[0007] When using a pressure regulation device of a spraying machine in this technical solution, the staff needs to first rotate and open the box door. After the box door is rotated and opened, the staff places the box body on the surface of the pressure regulator, and then pushes the box body to move the pressure regulator to the middle inside the box body by using the bayonet. After moving to this position, one end connecting pipe of the pressure regulator will be stuck between two clamping blocks. After being stuck, the staff rotates and closes the box door and locks it with a lock. At this time, the staff stabilizes the box body to make it placed upright, takes the lever and inserts it into the inside of the jack. After inserting, apply force to rotate the lever, and the lever will drive the shaft rod to rotate. After the shaft rod rotates, the threads provided on the surfaces of both ends of the shaft rod will engage with the threads on the inner surface of the shaft sleeve. Due to the engagement of the threads, the two shaft sleeves will move towards each other on the surfaces of both ends of the shaft rod. The two shaft sleeves moving towards each other will drive the clamping blocks connected to the outer surfaces to move together. In this way, the distance between the two clamping blocks will be shortened, and the one end connecting pipe of the pressure regulator between them will be clamped and fixed. In this way, the pressure regulator can be installed inside the box body.

[0008] Preferably, an air outlet is opened at the top of the other side of the outer part of the box body, and filters are fixed inside both the air outlet and the air inlet. Through the cooperation of the air outlet and the air inlet, the fan can generate flowing air inside the box body after running, achieving the effect of dehumidifying and removing impurities inside the box body. The installation of the filter prevents the sundries contained in the external air from entering the inside of the box body, playing a filtering role.

[0009] Preferably, a box door is rotatably installed on the front surface of the outer part of the box body through a hinge, and a viewing window is embedded in the middle of the box door. The installation of the box door enables the staff to rotate and open it to install or adjust the pressure regulator and other operations, providing an operating position. The installation of the viewing window enables the staff to see the situation inside the box body without opening the box door, playing a clear direct-viewing effect.

[0010] Preferably, bayonets are penetrated through the middle of both sides of the outer part of the box body. By setting the bayonets, the pipes connected to both ends of the pressure regulator can be directly stuck into them, achieving the effect of facilitating the direct covering and installation of the box body on the pressure regulator.

[0011] Preferably, a sliding rod is fixed at the rear end of one side inside the box body, a sliding sleeve is sleeved on the surface of the sliding rod, and the sliding sleeve is penetrated and installed at the other end of the clamping block. Through the cooperation of the sliding rod and the sliding sleeve, when the shaft rod engages with the shaft sleeve with threads and drives the clamping block to move, it limits the movement of the clamping block, achieving the effect of stabilizing the movement of the clamping block.

[0012] Preferably, threads are provided on both end surfaces of the shaft rod and the inner surface of the shaft sleeve, and they are meshed with each other. Through the cooperation of the shaft rod and the shaft sleeve, since threads are provided on both end surfaces and the inner surface, when the shaft rod rotates, the threads provided on both end surfaces thereof will mesh with the threads on the inner surface of the shaft sleeve. Due to the meshing of the threads, the two shaft sleeves will move towards or away from each other on both end surfaces of the shaft rod, achieving the effect of indirectly controlling the distance between the two clamping blocks through the meshing of the threads.

[0013] Preferably, a jack is penetrated and opened inside one end of the shaft rod. The opening of the jack is used for a lever for applying force to be inserted therein, so that it is convenient for the staff to apply a rotational force to the shaft rod and provides a force application point.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The present utility model utilizes the bayonet to snap the pressure regulator into the box body. The adjustable clamping blocks in the box body are used to clamp and fix one end thereof. In this way, the box body can protect the pressure regulator inside it, avoiding external physical damage. And a fan is installed on one side of the box body, which can form a flow ventilation duct to avoid moisture erosion of the pressure regulator. BRIEF DESCRIPTION OF THE DRAWINGS
