DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] As Figures 1 to 3 shown, the housing 10 of the handheld fire gun of the embodiment of the present application is provided with an oil tank 20 on one side, a quick release assembly 30 is arranged between the oil tank 20 and the housing 10, and the quick release assembly 30 comprises a self-locking air valve 1, a support 2, a spring 3 and a driving piece 4. The self-locking air valve 1 is used for connecting a first oil pipe 40 in the oil tank 2 and a second oil pipe 50 in the housing 10. The fixed part 21 of the support 2 is fixedly installed on the oil tank 20, the support part 22 of the support 2 is located on the outer side of the housing 10, one end of the spring 3 abuts against the support part 22, the operating end 41 of the driving piece 4 extends out of the support part 22 and is located on the outer side of the housing 10, and the movable end 42 of the driving piece 4 abuts against the other end of the spring 3. When the oil tank 2 is installed on one side of the housing 10, the movable end 42 abuts against or extends into the housing 10 under the action of the supporting force of the spring 3.

[0033] It can be understood that, since the oil tank 20 is mounted on the casing 10 through the quick release assembly 30 of the embodiment, when a user needs to dismount the oil tank 20, only needs to open the self-locking air valve 1, pull the driving member 4 through the operation end 41, and separate the movable end 42 of the driving member 4 from the casing 10, so that the oil tank 20 can be dismounted, without using professional tools, the oil tank 20 can be quickly dismounted, time and energy are saved, and the user experience is better. Similarly, when a user needs to mount the oil tank 20, only needs to abut or insert the movable end 42 of the driving member 4 from the casing 10, and then close the self-locking air valve 1, so that the oil tank 20 can be stably mounted on the casing 10.

[0034] As shown in the drawings, in one embodiment of the utility model, the self-locking air valve 1 can include a male head 11 and a female head 12, the male head 11 is fixed on the casing 10, the female head 12 includes a female head core 121 fixed on the oil tank 20 and a sleeve 122 sleeved outside the female head core 121, the female head core 121 is internally provided with a first cavity 121a suitable for the male head 11 to extend into, the side wall of the female head core 121 is provided with a cavity 121b, the cavity 121b is internally provided with a ball 123, a sealing ring (not shown in the figure) is arranged between the cavity 121b and the sleeve 122, and a self-locking spring 124 is arranged between the sleeve 122 and the female head core 121. Figures 4 to 6 When the male head 11 extends into the first cavity 121a of the female head core 121 and the sleeve 122 is at the first position, the self-locking air valve 1 is in a self-locking state, the sealing ring is pressed and limited to the ball 123 under the action of the sleeve 122 and the self-locking spring 124, at this time, the part of the ball 123 protruding from the inner wall of the female head core 121 can lock the front tapered surface of the male head 11; when the sleeve 122 is at the second position, the sealing ring loses the constraint of the sleeve 122 and no longer presses the ball 123, at this time, the ball 123 can move in the cavity 121b, so that the female head core 121 and the male head 11 can be separated.

[0035] Specifically, the female head core 121 can be externally provided with a first blocking ring 121c and a limiting protrusion 121d, the first blocking ring 121c and the limiting protrusion 121d are respectively arranged on the two sides of the self-locking spring 124 in the sleeve 122, and the sleeve 122 is limited between the first position and the second position.

[0036] Further, the female head core 121 can be internally provided with a reset spring 125 and a sliding block 126, when the reset spring 125 is at a first state, a protrusion 126a on the sliding block 126 abuts against the inner wall of the female head core 121, so that the female head core 121 is closed to the channel in the oil tank 20; when the male head 11 abuts against the sliding block 126, the protrusion 126a on the sliding block 126 is separated from the inner wall of the female head core 121, so that the channel between the oil tank 20 and the oil conveying pipe in the casing 10 is unobstructed, at this time, the reset spring 125 is further extruded by the sliding block 126 and is at a second state.

[0037] To avoid the reset spring 125 from flying the sliding block 126 in the process of recovering from the second state to the first state, a second blocking ring 121e can be arranged in the first cavity 121a of the female head core 121, and the position of the second blocking ring 121e can be between the position of the farthest distance that the sliding block 126 and the male head 11 can reach. In other embodiments of the application, the active space (i.e. the second cavity 121f of the female head core) of the reset spring 125 can be made larger than the active space (i.e. the first cavity 121a) of the male head 11 in the female head core 121, and a convex ring 126b with a diameter between the two diameters is arranged on the sliding block 126 to avoid being hit by the reset spring 125. The embodiments are not limited thereto.

[0038] As shown in Figure 2 and 3 In an embodiment of the utility model, the driving part 4 further includes a connecting part 43, the connecting part 43 is used to connect the operation end 41 and the movable end 42, and the support part 22 is provided with a through hole 23 suitable for the movement of the connecting part 43.

The connecting part 43 is provided with a groove suitable for the insertion of the limiting block 24 or a limiting hole suitable for the penetration of the limiting block 24. By arranging the limiting block 24, the movable position of the movable end 42 on the connecting part 43 can be limited, so that the movable end 42 does not excessively compress the spring 3, which affects the service life of the spring 3 and even causes damage to the spring 3.

[0040] In an embodiment of the utility model, the side of the support part 22 away from the shell 10 is provided with an inclined support part 25, and the end of the inclined support part 25 away from the support part 22 can abut against the oil tank 2. By arranging the inclined support part 25, the support part 22 can be provided with a support force opposite to the direction of the shell 1, so as to improve the stability of the support part 2.
