Description

Technical Field

[0001] The utility model relates to the technical field of spraying guns, in particular to a spraying gun convenient for cleaning. Background Art

[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as power. Spray guns are divided into two types: ordinary pressure type and pressurized type. There are also pressure type spray guns, Carle type spray guns, and automatic recovery type spray guns. In the construction of the water-based aluminum powder paint spraying process for the body primer of rail transit vehicles, a spraying gun is required during construction. When spraying the primer, a curing agent and a thinner are added to increase the number of sprays. At the same time, the film thickness increased by spraying is controlled. By increasing the thinner, each spray becomes thinner, so that both the film thickness and the brightness can meet the requirements.

[0003] The existing Chinese patent CN214682371U discloses a spray gun for paint spraying on November 12, 2021, which includes a spray gun body. A discharge pipe is provided at the bottom of the spray gun body. A tank body and a tank cover are provided below the spray gun body. The discharge pipe penetrates through the tank cover, and the bottom end of the discharge pipe is located inside the tank body. A filter ring is provided inside the tank body, and the filter ring is sleeved outside the discharge pipe. The outer wall of the filter ring is fixedly connected to the inner wall of the tank body. A feed pipe is provided at the top of the tank cover, and a pipe cap is provided at the top end of the feed pipe. A connecting ring is fixedly connected to the top of the tank body, and a limiting pipe is fixedly connected to the top of the connecting ring. The limiting pipe is sleeved outside the tank cover. Movable plates are provided on both sides of the connecting ring.

[0004] However, when the above device is spraying, paint is sprayed through the nozzle of the spray gun body. During spraying, the paint is likely to float due to the wind, and thus it is likely to adhere to the spray gun body, making it not very convenient to clean later. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a spraying gun convenient for cleaning, so as to solve the problem that when the above device is spraying, paint is sprayed through the nozzle of the spray gun body. During spraying, the paint is likely to float due to the wind, and thus it is likely to adhere to the spray gun body, making it not very convenient to clean later as mentioned in the above background art.

[0006] To achieve the above object, the present utility model provides the following technical solution: A spraying gun that is convenient to clean, comprising a gun body, a spraying trigger, and a gun nozzle.

[0007] Among them, the paint shielding disc includes a locking bolt, an assembly sleeve, an internal sleeve cavity, and a horn-shaped shielding cover. The locking bolt is provided inside the assembly sleeve. The horn-shaped shielding cover is provided at the front end of the assembly sleeve. The internal sleeve cavity is provided inside the horn-shaped shielding cover. The assembly sleeve is connected to the gun body through the locking bolt.

[0008] Among them, the positioning pulling rod includes a connecting end post, a connecting round rod, a metal screw rod, and a locking nut. The connecting round rod is provided at the outer end of the connecting end post. The metal screw rod is provided at the outer end of the connecting round rod. The locking nut is provided on the periphery of the metal screw rod. The metal screw rod is sleeved in the groove of the spraying trigger. The connecting end post is connected to the gun body.

[0009] Among them, the carrying hanging hook includes a lifting cavity, a lifting handle rod, and a hanging ring. The lifting cavity is provided inside the lower end of the lifting handle rod. The hanging ring is provided at the upper end of the lifting handle rod. The lifting handle rod is connected to the gun body.

[0010] Among them, the anti-slip rubber pad and the gun body are adhesively connected by glue, and the connection parts are aligned.

[0011] Among them, the paint shielding disc is sleeved on the peripheral side of the front end of the gun body.

[0012] Among them, the spraying trigger and the gun body are movably connected by a shaft rod. A groove hole is provided inside the lower end of the spraying trigger.

[0013] In summary, due to the adoption of the above technology, the beneficial effects of the present utility model are as follows:

[0022] Embodiment 1

[0023] Refer to Figure 1 and Figure 2, A spray gun that is convenient to clean, comprising a spray gun body 2, a spray trigger 5, and a spray gun nozzle 6. The spray gun nozzle 6 is installed and connected to the front end of the spray gun body 2. A spray trigger 5 is provided on the front side of the lower end of the spray gun body 2. A positioning pull rod 4 is provided between the spray trigger 5 and the spray gun body 2. An anti-slip rubber pad 3 is provided at the handle of the spray gun body 2. A carrying hanging hook 7 is provided at the upper end of the spray gun body 2. A paint shielding disc 1 is provided on the spray gun body 2 at the rear side of the spray gun nozzle 6.

[0024] In the present utility model, the paint shielding disc 1 includes a locking bolt 11, an assembly sleeve 12, an inner sleeve cavity 13, and a horn-shaped shielding cover 14. The locking bolt 11 is provided inside the assembly sleeve 12. The horn-shaped shielding cover 14 is provided at the front end of the assembly sleeve 12. The inner sleeve cavity 13 is provided inside the horn-shaped shielding cover 14. The assembly sleeve 12 is connected to the spray gun body 2 through the locking bolt 11. The assembly sleeve 12 of the paint shielding disc 1 is installed and connected to the spray gun body 2 through the locking bolt 11. Thus, through the tightening and loosening of the locking bolt 11, the assembly sleeve 12 is convenient to disassemble. When the assembly sleeve 12 is installed and fixed, it can drive the horn-shaped shielding cover 14 to be installed and blocked. Due to the area of the inner sleeve cavity 13 of the horn-shaped shielding cover 14, a concave surface is formed, so that the paint can adhere to the inside and effectively collect and drip onto the paper on the ground, avoiding environmental pollution caused by messy dripping.

[0025] In the present utility model, the anti-slip rubber pad 3 and the spray gun body 2 are adhesively connected by glue, and the connection parts are aligned, so that they can be installed and fixed, and the outer sides are aligned, so that there will be no obstruction during use.

[0026] In the present utility model, the paint shielding disc 1 is sleeved on the peripheral side of the front end of the spray gun body 2, so as to effectively shield and protect.

[0027] In the present utility model, the spray trigger 5 and the spray gun body 2 are movably connected by a shaft rod. A groove hole is provided inside the lower end of the spray trigger 5, so that it can be pressed and used movably. Due to the groove hole at the lower end of the spray trigger 5, the positioning pull rod 4 can pass through and be installed for use.

[0028] Working principle: When in use, the spray gun body 2 can be hung at a designated position through the carrying hanging hook 7 at the upper end and can also be carried by lifting. During operation, a person holds the outer side of the anti-slip rubber pad 3 and hooks the fingers on the spraying trigger 5 to press. Thus, the spray gun body 2 can spray the connected paint raw material through the connected air pipe from the spray gun nozzle 6, and then effective spraying construction can be carried out. The person can also position through the positioning pulling rod 4 so that the spraying trigger 5 always maintains a spraying pressure, which is convenient for uniform spraying construction. The paint sprayed by the spray gun nozzle 6 passes through the paint shielding disc 1 on the peripheral side of the front end of the spray gun body 2, so as to be effectively shielded and prevent the paint from adhering to the spray gun body 2. During cleaning, the person only needs to disassemble the paint shielding disc 1 for cleaning, making the cleaning more convenient.
