Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 —9: A high-pressure water gun with a self-locking device includes a gun body 1, a handle 2, and a trigger 3. One end of the trigger 3 is hinged to the gun body 1, and the other end moves within a retaining ring 4 at the front end of the handle 2. The retaining ring 4 is provided with a self-locking device located below the trigger 3 to fix the trigger 3 and keep the water gun in the open state. The self-locking device includes a supporting spring 5 and a button 6. The supporting spring 5 is located inside the retaining ring 4, with one end fixed and the other end engaging and supporting the button 6. The button 6 passes through the retaining ring 4 and can move up and down under the support of the supporting spring 5, overcoming the elastic force of the supporting spring 5 and acting on the bottom of the trigger 3 to lock the trigger 3.

[0026] like Figure 2As shown, the specific locking method is as follows: a vertically upward locking protrusion 601 is provided on one side edge of the end face of the button 6, a locking hook 602 is provided on the top of the locking protrusion 601, a sliding groove 301 is provided on the bottom of the trigger 3, and a locking groove 302 is provided at the end of the sliding groove 301 to lock and adapt to the locking hook 602. The sliding groove 301 is inclined from deep to shallow outward from the locking groove 302 to facilitate the sliding of the locking hook 602 and to prevent it from falling off after locking. Grip trigger 3 firmly and press button 6. The locking protrusion 601 will rise upward, causing the locking hook 602 to enter the slide groove 301. Slightly loosen the grip on the trigger, allowing the locking hook 602 to slide into the locking groove 302. After fully releasing the trigger, the locking hook 602 and the locking groove 302 will be completely locked, keeping the water gun in the on state. When it is necessary to unlock, simply grip trigger 3 firmly, bringing it closer to handle 2. Under the reaction force of the support spring 5, the locking hook 602 on the button will disengage from the locking groove 302 along the slide groove 301, resetting the button. Release trigger 3, and trigger 3 will automatically reset, stopping the water gun from working.

[0027] like Figure 7 , 8 As shown in Figure 9, in this solution, button 6 is entirely supported by the support spring 5. Specifically, a fixing block 603 is provided on the other side edge of the end face of button 6. The fixing block 603 and the locking protrusion 601 have the same width, and both have slots 606 of the same depth at their connection with the end face of button 6. A U-shaped opening 521 is provided at the point where the support spring 5 engages with button 6. The U-shaped opening 521 of the support spring 5 passes through the fixing block 603 and the locking protrusion 601 and engages in the slots 606 of both, thereby providing stable support for button 6, making the button move up and down more smoothly, and avoiding friction with the inner wall of the retaining ring, thus increasing its service life.

[0028] To enhance the structural strength and stability of button 6 during use, a reinforcing rib 604 is provided on the end face of button 6, located between the fixing block 603 and the locking protrusion 601, and connected to both. This prevents the locking protrusion 601 from breaking during long-term locking and unlocking of button 6 with wrench 3. Each of the four side walls of button 6 is provided with a limiting block 605 to prevent button 6 from falling out of the retaining ring 4. The inner wall of the retaining ring 4 is also provided with a guide groove 42. The limiting blocks 605 on both sides of button 6 are located within the guide groove 42, ensuring that when button 6 moves up and down, the limiting blocks 605 can only slide up and down within the guide groove 42. This provides more precise guidance for the up and down movement of button 6, prevents button 6 from feeling loose, and prevents button from wobbling freely, making the locking and unlocking of button 6 with wrench 3 more precise, quick, and tactile.

[0029] like Figure 4 , 6As shown in Figure 9, one end of the support spring 5 is a support end 52, which is engaged with the button 6, and the other end is a fixing end 51, which is fixed inside the guard ring 4. The inner wall of the guard ring 4 is provided with two support columns 41, and the two support columns 41 are laterally provided with slots 411. The fixing end 51 is laterally inserted into the slots 411, which provides stable support for fixing the support spring 5. In particular, the use of two support columns 41 increases the fixing area of ​​the fixing end 51, making the overall fixing and support of the support spring 5 more secure. Moreover, the insertion installation is simple in structure and convenient and quick to install.

[0030] To enhance the stability of the fixed spring 5, a locking tongue 511 is provided at the tail of the fixed end 51 of the support spring 5. The width of the locking tongue 511 is smaller than that of the fixed end 51, so that the end face of the fixed end directly acts on the side wall of the support column 41 to prevent the support spring 5 from moving. The locking tongue 511 is located in the slot 411 of the support column 41, and the tail of the locking tongue 511 is bent downward. The bent part can act on the other side wall of the support column 41, so that the fixed end 51 of the support spring 5 is just locked on the second support column 41, further preventing the support spring 5 from moving and ensuring that the support spring 5 can provide more stable and firm support for the button 6.

[0031] like Figure 9 As shown, in order to enhance the restoring elasticity of the support spring 5, a bending portion 53 is provided between the support end 52 and the fixed end 51 of the support spring 5, so that the support end 52 is lower than the fixed end 51 and the two remain parallel. The bending portion 53 enhances the elasticity on the one hand, and improves the structural strength of the support spring 5 on the other hand, avoiding fatigue caused by long-term bending, which could lead to weakening or breakage of the elasticity.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
