Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a paint spraying device. Background Art

[0002] The spray gun is the most common paint spraying device. Generally, the spray gun is connected to the paint through a pipe. The existing spray gun generally includes a handheld handle and a nozzle. The handle is provided with a rebound pressing rod. The paint is sprayed out from the nozzle by squeezing the pressing rod. However, the existing spray gun has certain disadvantages. The pressing rod of the spray gun cannot be locked. When using, the user needs to continuously squeeze the pressing rod and continuously apply force with the palm, which easily causes palm fatigue.

[0003] Therefore, those skilled in the art provide a paint spraying device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a paint spraying device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A paint spraying device comprises a spray gun body, the left end of the spray gun body is connected to an adjusting knob, the left end of the adjusting knob is detachably connected to a nozzle, the right end of the spray gun body is connected to a connecting nozzle, the lower end of the spray gun body is rotatably connected to a rebound pressing rod, the lower surface of the spray gun body is fixedly connected to a handle, the rebound pressing rod is located on the left side of the handle, and a locking structure is arranged inside the handle.

[0007] As a further solution of the utility model: the locking structure includes an inner groove, which is opened on the left side of the handle, and a sliding groove is opened on the surface of the handle. A sliding rod is slidably arranged inside the sliding groove, and both ends of the sliding rod extend to the outside of the handle and are enlarged to prevent the sliding rod from falling off from the inside of the sliding groove. A connecting column is fixedly connected to the inner wall of the inner groove, and the connecting column is located on the lower side of the sliding groove. A spring is directly connected to the connecting column and the sliding rod, and a locking opening is opened on the surface of the handle facing the rebound pressing rod.

[0008] As a further solution of the utility model: the locking opening is arranged in an arc shape, and the length of the arc is greater than half the circumference of the circle where the arc is located.

[0009] As a further solution of the present invention: the width of the locking opening is greater than the diameter of the sliding rod.

[0010] As a further solution of the utility model: a stopper is fixedly connected to the left surface of the rebound-type pressing rod, and the upper surface of the stopper abuts against the lower surface of the spray gun body.

[0011] As a further solution of the present invention: anti-slip texture is arranged on the right side of the handle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a sliding rod and a locking mouth, when the rebound pressing rod and the handle are held close to each other, the sliding rod is inserted into the locking mouth to lock the rebound pressing rod. At this time, paint can be sprayed continuously, and the fingers will not apply gripping force to the rebound pressing rod, which can avoid hand muscle fatigue. When the spraying is finished, the rebound pressing rod can continue to be pressed slightly so that the sliding rod is no longer blocked by the inner wall of the locking mouth and the inner wall of the slide groove. Under the elastic force of the spring, the sliding rod will be reset, and by setting a block, the block can prevent the angle between the rebound pressing rod and the handle from being too large, which makes it inconvenient to hold the handle and the rebound pressing rod with one hand.

[0018] See also Figures 1 to 3 In an embodiment of the utility model, a paint spraying device includes a spray gun body 1, the left end of the spray gun body 1 is connected with an adjusting knob 3, the left end of the adjusting knob 3 is detachably connected with a nozzle 4, the right end of the spray gun body 1 is connected with a connecting nozzle 5, the lower end of the spray gun body 1 is rotatably connected with a rebound pressing rod 6, the lower surface of the spray gun body 1 is fixedly connected with a handle 2, the rebound pressing rod 6 is located on the left side of the handle 2, and a locking structure is arranged inside the handle 2.

[0019] Preferably, the locking structure includes an inner groove 12, which is opened on the left side of the handle 2. A slide groove 8 is opened on the surface of the handle 2. A slide rod 9 is slidably arranged inside the slide groove 8. Both ends of the slide rod 9 extend to the outside of the handle 2 and are enlarged to prevent the slide rod 9 from falling off from the inside of the slide groove 8. A connecting column 11 is fixedly connected to the inner wall of the inner groove 12. The connecting column 11 is located on the lower side of the slide groove 8. A spring 10 is directly connected to the connecting column 11 and the slide rod 9. A locking opening 13 is opened on the surface of the rebound pressing rod 6 facing the handle 2.

[0020] Preferably, the locking opening 13 is arranged in an arc shape, and the length of the arc is greater than half the circumference of the arc in the circle, and the width of the opening of the locking opening 13 is greater than the diameter of the slide rod 9. After the slide rod 9 is inserted into the locking opening 13, the rebound pressing rod 6 can be locked. At this time, during spraying, it can continue without applying pressure on the rebound pressing rod 6 with fingers, thereby avoiding hand muscle fatigue.

[0021] Preferably, a block 7 is fixedly connected to the left surface of the rebound type pressing rod 6, and the upper surface of the block 7 abuts against the lower surface of the spray gun body 1. When the block 7 contacts the spray gun body 1, the rebound type pressing rod 6 is reset to the initial state. The block 7 can prevent the angle between the rebound type pressing rod 6 and the handle 2 from being too large, which makes it inconvenient to hold the handle 2 and the rebound type pressing rod 6 with one hand.

[0022] Preferably, the right side of the handle 2 is provided with anti-slip texture.

[0023] The working principle of the utility model is as follows: when using the spraying device, after holding the handle 2, four fingers other than the thumb can be used to press the resilient pressing rod 6, so that the resilient pressing rod 6 and the handle 2 are close to each other, and paint is sprayed from the nozzle 4. Holding the resilient pressing rod 6 for a long time will cause fatigue to the hand muscles. When the resilient pressing rod 6 and the handle 2 are close to each other, the sliding rod 9 can be pushed so that the sliding rod 9 is stuck in the locking port 13, thereby locking the resilient pressing rod 6. At this time, the paint can be sprayed continuously, and the fingers will not apply gripping force to the resilient pressing rod 6, and During this process, due to the resistance of the inner wall of the locking port 13 and the inner wall of the slide groove 8 to the sliding rod 9, the spring 10 cannot pull the sliding rod 9 out of the locking port 13, so that the rebound pressing rod 6 can be kept in this state. When the spraying is finished, the rebound pressing rod 6 can continue to be pressed slightly so that the sliding rod 9 is no longer blocked by the inner wall of the locking port 13 and the inner wall of the slide groove 8. Under the elastic force of the spring 10, the sliding rod 9 will be reset. After releasing the fingers holding the rebound pressing rod 6, the rebound pressing rod 6 contacts the bottom of the spray gun body 1 through the block 7. At this time, the rebound pressing rod 6 is in a reset state.

[0024] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
