Description

Technical Field

[0001] This utility model relates to a spray gun, and more particularly to a spray gun trigger structure that is prevented from accidental activation and can be locked. Background Technology

[0002] In fields such as composite material manufacturing, corrosion protection engineering, and building repair, spraying resins (such as epoxy resin, polyurethane resin, and unsaturated polyester) has become an efficient and uniform application method. Unlike traditional liquid coatings, resin materials typically have higher viscosity, faster curing rates, and strict requirements on mixing ratios and spraying pressure.

[0003] While most general-purpose spray guns on the market can achieve basic spraying functions, they generally have the following problems when applied to high-viscosity, fast-curing resin systems: First, the trigger structure lacks an effective anti-accidental trigger design. If the trigger is accidentally triggered during handling, adjustment of the work position, or pause in operation, it is very easy to cause unevenly mixed or unprepared resin to be sprayed out, which not only wastes expensive raw materials but may also contaminate the surface of the workpiece. Third, although some spray guns are equipped with mechanical locks, the unlocking process is cumbersome, affecting the efficiency of continuous operation.

[0004] Therefore, there is an urgent need for a spray gun trigger structure that is both highly reliable, prevents accidental activation, and is lockable. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a spray gun trigger structure that is both highly reliable, prevents accidental activation, and is lockable.

[0006] The technical solution of this utility model is as follows: a spray gun trigger structure that is anti-accidental and lockable, including a gun body, a trigger body, a rotating shaft, an extension plate, a boat-shaped button, and a limit block. The trigger body is rotatably mounted on the upper part of the gun body through the rotating shaft. An extension plate is provided on the side of the trigger body near the gun body. The extension plate is inserted into the gun body and slidably connected to it. A slot is provided on the upper part of the extension plate. A boat-shaped button is rotatably mounted on the gun body on the side of the extension plate. A limit block is provided on the boat-shaped button.

[0007] In one embodiment, when the trigger body is pressed, the limiting block on the boat-shaped button can be engaged in the slot, and when the trigger body is not pressed, the limiting block can be engaged at the end of the extension plate.

[0008] In one embodiment, the rotating shaft is detachable and installable.

[0009] In one embodiment, the gun body is further provided with a spring rod, which is symmetrically arranged on the upper part of the gun body, and the end of the spring rod contacts the side of the trigger body.

[0010] In one embodiment, the device also includes a guide cylinder and a sliding steel ball. The guide cylinder is located on the side of the boat-shaped button near the extension plate, and the sliding steel ball is located inside the guide cylinder. A row of positioning grooves is formed in the trigger body on one side of the guide cylinder.

[0011] In one embodiment, the steel ball is slidably disposed within the guide cylinder, and the sliding steel ball is positioned within the positioning groove.

[0012] Beneficial effects: This invention, by pressing the lower part of the boat-shaped button, places the limiting block on the moving path of the extension plate, preventing the trigger body from rotating. In this state, the spray gun cannot operate, and accidental activation is prevented. When the spray gun needs to be kept operational, the limiting block moves away from the moving path of the extension plate, the trigger body is pressed, the extension plate is inserted into the gun body, and then the lower part of the boat-shaped button is pressed, causing the limiting block to insert into the slot, thus fixing the position of the trigger body and keeping the spray gun operational. Furthermore, the boat-shaped button and trigger body can be operated with one hand, offering great convenience. The sliding steel ball increases the counterweight on the other side of the boat-shaped button, and its cooperation with the positioning groove slightly fixes the position of the boat-shaped button, preventing external forces from easily causing positional changes.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] Example: A lockable spray gun trigger structure that prevents accidental activation, such as... Figures 1-3As shown, the device includes a gun body 1, a trigger body 2, a rotating shaft 3, an extension plate 4, a boat-shaped button 6, and a limiting block 7. The trigger body 2 is rotatably mounted on the upper part of the gun body 1 via the rotating shaft 3, which is detachable and installable. The trigger body 2 extends downward to the grip of the gun body 1. The lower part of the trigger body 2 is designed to mimic the shape of a human finger for easy pressing and improved pressing comfort. An extension plate 4 is provided on the side of the trigger body 2 near the gun body 1. The extension plate 4 is inserted into the gun body 1 and slides with it. Next, a slot 5 is provided on the upper part of the extension plate 4, and a boat-shaped button 6 is rotatably provided on the gun body 1 on the side of the extension plate 4. A limit block 7 is provided on the boat-shaped button 6. When the trigger body 2 is pressed, the limit block 7 on the boat-shaped button 6 can be inserted into the slot 5. When the limit block 7 is inserted into the slot 5, the trigger body 2 is in the pressed state, and the gun body 1 remains in the working state. When the trigger body 2 is not pressed, the limit block 7 can be locked at the end of the extension plate 4, thereby preventing accidental activation when the trigger body 2 is pressed.

[0020] A lockable spray gun trigger structure that prevents accidental activation, compared with the prior art: When the spray gun is not working, pressing the lower part of the boat-shaped button 6 causes the limiting block 7 to be in the moving path of the extension plate 4. At this time, the extension plate 4 cannot move due to the blocking effect of the limiting block 7, so the trigger body 2 cannot rotate, and the spray gun cannot work, preventing accidental activation. When it is necessary to keep the spray gun working, first press the upper part of the boat-shaped button 6, causing the limiting block 7 to leave the moving path of the extension plate 4. Then press the trigger body 2, and the extension plate 4 is inserted into the gun body 1. Then press the lower part of the boat-shaped button 6, and the limiting block 7 is inserted into the slot 5, fixing the position of the trigger body 2 and keeping the spray gun working. When it is necessary to deactivate the spray gun, press the upper part of the boat-shaped button 6 again, causing the limiting block 7 to leave the slot 5.

[0021] like Figure 1 and Figure 2 As shown, it also includes an elastic rod 8. The upper part of the gun body 1 is symmetrically provided with elastic rods 8. The end of the elastic rod 8 contacts the side of the trigger body 2. The elastic rod 8 is composed of a sliding rod slidably connected to the upper part of the gun body 1 and a spring connected between the sliding rod and the gun body 1. When the trigger body 2 is pressed, the elastic rod 8 deforms. When the trigger body 2 is not fixed, the elastic rod 8 resets and drives the trigger body 2 to automatically reset, improving the convenience of using the equipment.

[0022] like Figure 3 and Figure 4As shown, it also includes a guide cylinder 9 and a sliding steel ball 10. The guide cylinder 9 is provided in the middle of the side of the boat-shaped button 6 near the extension plate 4. The guide cylinder 9 swings with the boat-shaped button 6. The sliding steel ball 10 is slidably arranged in the guide cylinder 9. A row of positioning grooves 11 is opened in the trigger body 2 on one side of the guide cylinder 9. The sliding steel ball 10 can be in the positioning grooves 11. When the boat-shaped button 6 is rotated, the sliding steel ball 10 can increase the counterweight on the other side of the boat-shaped button 6. At the same time, the sliding steel ball 10 cooperates with the positioning grooves 11 to make the position of the boat-shaped button 6 slightly fixed, thereby preventing the position of the boat-shaped button 6 from easily changing due to external force.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
