Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, specifically a spray gun with a locking function. Background Technology

[0002] A spray gun is a plastic spraying device commonly used for liquid packaging such as cleaning agents, disinfectants, and toilet cleaners. It features a hand-operated design and is suitable for household cleaning, gardening, and other scenarios. Its core characteristics are fine atomization, simple structure, and low cost.

[0003] Existing spray guns are typically mounted on bottled items such as cleaning agents. When carrying or preparing to use them, users need to hold the bottle with one hand while simultaneously controlling the trigger. When holding the gun, the palm naturally wraps around the gun, and the index finger is very likely to come into contact with the trigger area. At the same time, due to the weight of the bottled liquid, the user needs to adjust the point of force when holding the gun, which further increases the probability of accidental activation. This can cause the spray gun to accidentally spray out the liquid inside the bottle. If the liquid inside the bottle contains corrosive or irritating ingredients, accidental spraying may cause skin contact or inhalation risks. Therefore, a spray gun with a locking function is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a spray gun with a locking function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray gun with a locking function, comprising a spray gun housing and a nozzle, wherein a rotating shaft is rotatably connected to the top of the spray gun housing, and a trigger is mounted in cooperation with the rotating shaft, and further comprising:

[0006] A locking mechanism, located on the housing of the spray gun, is used to lock the trigger;

[0007] The locking structure includes a ring-shaped component fixed to the outer surface of the rotating shaft. A slot is provided on one side of the ring-shaped component. A sliding groove is provided inside the spray gun housing. A movable component is slidably connected inside the sliding groove. A button is fixed to the top of the movable component. A limit plate is fixed to one side of the movable component. Two sets of locking holes are provided inside the sliding groove. A slot is provided inside the movable component. A reset spring and a movable plate are fitted inside the slot. A protrusion is fixed to one side of the movable plate.

[0008] As described above, the annular component is embedded inside the spray gun housing and is rotatably connected to the spray gun housing, and the limiting plate is movably engaged with the slot.

[0009] As mentioned above, there are two sets of movable plates, and the reset spring is elastically supported between the two sets of movable plates.

[0010] As mentioned above, one side of the protrusion is arc-shaped, and the protrusion engages with one of the sets of locking holes.

[0011] As mentioned above, the surface of the button is corrugated.

[0012] Compared with existing technologies, this type of spray gun with locking function has the following advantages:

[0013] I. This utility model allows the movable part to move along the outer surface of the slide groove through the cooperation between the movable part and the slide groove, thereby driving the limiting plate to engage with the slot. This restricts the rotation of the ring part. At the same time, the cooperation between the ring part and the rotating shaft positions the trigger, locking the trigger to prevent accidental firing.

[0014] Second, this utility model utilizes the elastic force of the return spring. When the protrusion moves to the position corresponding to the locking hole, the return spring will push the movable plate to slide along the inner wall of the groove. Thus, the movable plate can drive the protrusion to engage with the locking hole, preventing the movable part from being shaken and causing the limiting plate to separate from the locking groove, thereby improving the stability after the trigger is locked.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model provides a spray gun with a locking function, including a spray gun housing 1 and a nozzle 2. A rotating shaft 3 is rotatably connected to the top of the spray gun housing 1, and a trigger 4 is installed in cooperation with the rotating shaft 3. It also includes:

[0025] A locking structure is provided on the housing 1 of the spray gun to lock the trigger 4;

[0026] The locking structure includes an annular component 5, which is fixed to the outer surface of the rotating shaft 3. A slot 6 is provided on one side of the annular component 5. A sliding groove 7 is provided inside the spray gun housing 1. A movable component 8 is slidably connected inside the sliding groove 7. A button 9 is fixed to the top of the movable component 8. A limit plate 10 is fixed to one side of the movable component 8. Two sets of locking holes 11 are provided inside the sliding groove 7. A slot 12 is provided inside the movable component 8. A reset spring 13 and a movable plate 14 are sleeved inside the slot 12. A protrusion 15 is fixed to one side of the movable plate 14.

[0027] The cooperation between the movable part 8 and the slide 7 allows the movable part 8 to move along the outer surface of the slide 7, thereby driving the limiting plate 10 to engage with the slot 6. This restricts the rotation of the ring part 5. At the same time, the cooperation between the ring part 5 and the rotating shaft 3 positions the trigger 4, locking the trigger 4 to prevent accidental firing.

[0028] like Figure 3 As shown, the annular part 5 is embedded inside the spray gun housing 1 and is rotatably connected to the spray gun housing 1, and the limiting plate 10 is movably engaged with the slot 6.

[0029] Through the cooperation between the annular part 5 and the spray gun housing 1, when the trigger 4 is pressed, the annular part 5 will be rotated together through the rotating shaft 3. At this time, through the cooperation between the limiting plate 10 and the slot 6, when the limiting plate 10 and the slot 6 are engaged, the rotation of the annular part 5 will be restricted, thereby locking the trigger 4.

[0030] like Figure 5 As shown, there are two sets of movable plates 14, and the return spring 13 is elastically supported between the two sets of movable plates 14.

[0031] The design of the return spring 13 enables the movable plate 14 to have good elastic return performance. Since the return spring 13 is in a compressed state, it will apply an elastic force to the movable plate 14, which can drive the protrusion 15 to engage with the locking hole 11 through the movable plate 14, making the movable part 8 less likely to move and improving the stability after locking the trigger 4.

[0032] like Figure 3 , 5 As shown, one side of the protrusion 15 is arc-shaped, and the protrusion 15 engages with one of the sets of locking holes 11.

[0033] With the design of the protrusion 15, since one side of the protrusion 15 is arc-shaped, when the protrusion 15 and the card hole 11 are squeezed, the movable plate 14 can be driven by the protrusion 15 to compress the reset spring 13, which makes it easy to control the separation of the protrusion 15 and the card hole 11, and makes it easy for the limiting plate 10 to engage or disengage from the card slot 6.

[0034] like Figure 6 As shown, the surface of button 9 is corrugated.

[0035] The design of button 9, with its corrugated surface, facilitates movement by pushing button 9, thereby controlling the movement of movable part 8 and making it easy to control the engagement or disengagement of limit plate 10 and slot 6.

[0036] Working principle:

[0037] When the spray gun housing 1 is idle, the user can push the button 9 and move the movable part 8 along the outer surface of the slide groove 7, thereby causing the limiting plate 10 to engage with the slot 6, thus limiting the rotation of the ring part 5. When the protrusion 15 moves to the position corresponding to the locking hole 11, the elastic force of the return spring 13 will push the movable plate 14 to slide along the inner wall of the slot 12, thereby causing the protrusion 15 to engage with the locking hole 11 through the movable plate 14, thus locking the trigger 4 and preventing accidental spraying.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
