[0024] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0025] Embodiment 1

[0026] As Figures 1 - 5 shown, a high-pressure water gun for workpiece cleaning proposed in an embodiment of the present application includes a main body 1 of the high-pressure water gun. A trigger 2 is hinged on the main body 1 of the high-pressure water gun. A fixed cylinder 3 is hinged on the main body 1 of the high-pressure water gun. A movable groove 4 is provided in the fixed cylinder 3. The movable groove 4 is provided along the length direction of the fixed cylinder 3. A sliding rod 5 that is slidably engaged with the movable groove 4 is hinged on the trigger 2. A compression spring 6 is provided between the sliding rod 5 and the movable groove 4. Two ends of the compression spring 6 are respectively fixedly connected to the sliding rod 5 and the movable groove 4. A locking portion is provided on the sliding rod 5. A locking mechanism that acts on the locking portion and locks or unlocks the sliding rod 5 is provided on the fixed cylinder 3;

[0027] In the initial state, the high-pressure water gun main body 1 is in the closed state, the trigger 2 is in the released state, the sliding rod 5 is at the initial position, the compression spring 6 is in the natural state. When cleaning the workpiece, the trigger 2 is pressed, the high-pressure water gun main body 1 is in the open state, the sliding rod 5 is driven by the trigger 2 to slide to the limit position in the movable groove 4, driving the locking part to move together, and the compression spring 6 is squeezed. During this process, the locking mechanism acts on the locking part to lock the sliding rod 5, that is, the sliding rod 5 cannot slide, and the compression spring 6 cannot return to the natural state, thereby locking the trigger 2. The operator releases the trigger 2, and the trigger 2 remains in the pressed state without the need to keep pressing the trigger 2 with the hand, which is convenient and labor-saving to use and avoids palm soreness caused by long-term pressing. On the contrary, when the cleaning is completed, the locking mechanism acts on the locking part to unlock the sliding rod 5, the compression spring 6 returns to the natural state, the sliding rod 5 slides to the initial position, driving the locking part to move together, the trigger 2 is in the released state, and the high-pressure water gun main body 1 is closed;

[0028] In summary, when the workpiece is cleaned in this application, the trigger 2 is pressed, the high-pressure water gun main body 1 is in the open state, and then the trigger 2 can be locked. The operator releases the trigger 2, and the trigger 2 remains in the pressed state without the need to keep pressing the trigger 2 with the hand. On the contrary, when the cleaning is completed, the trigger 2 is unlocked, the trigger 2 is in the released state, and the high-pressure water gun main body 1 is closed, which is convenient and labor-saving to use and avoids palm soreness caused by long-term pressing. Therefore, it is more practical.

[0029] Embodiment 2

[0030] Embodiment 2 proposes a structure of the locking part and the locking mechanism on the basis of Embodiment 1.

[0031] As Figure 4 shown, in some embodiments, the locking part includes a fixed block 7 provided on the sliding rod 5 and inserted and matched with the movable groove 4. The fixed block 7 is fixed on the sliding rod 5, and a first annular groove 8 is formed on the fixed block 7. The cross-sectional structure of the first annular groove 8 is an isosceles trapezoid;

[0032] Referring to the above, in the initial state, the sliding rod 5 is at the initial position. When the sliding rod 5 slides to the limit position, it drives the fixed block 7 to move together and be inserted into the movable groove 4. On the contrary, when the sliding rod 5 slides to the initial position, it drives the fixed block 7 to move together and withdraw from the movable groove 4.

[0033] As Figure 4 shown, in some embodiments, the free end of the fixed block 7 is configured as a tapered shape that contracts inward;

[0034] Referring to the above, when the fixed block 7 is inserted into the movable groove 4, the inwardly contracting tapered setting can avoid movement interference, enable the fixed block 7 to smoothly enter the movable groove 4, and is more convenient to use.

[0035] As Figure 5 shown, in some embodiments, the locking mechanism includes an annular groove 9 and a plurality of receiving grooves 10 that are both formed in the fixed cylinder 3 and communicate with each other. The annular groove 9 is formed along the length direction of the fixed cylinder 3, the receiving grooves 10 are vertically distributed with respect to the annular groove 9, and the plurality of receiving grooves 10 are distributed in an annular array. The receiving grooves 10 communicate with the movable groove 4, and balls 11 are movably arranged in the receiving grooves 10. The balls 11 cannot completely exit the receiving grooves 10. An elastic limiting member that acts on the plurality of balls 11 and limits or releases the limit of the plurality of balls 11 is slidably arranged in the annular groove 9;

[0036] Referring to the above, in the initial state, the elastic limiting member is located at the initial position and in a natural state. The elastic limiting member blocks the communication between the receiving groove 10 and the annular groove 9, and the balls 11 cannot enter the annular groove 9. When the fixed block 7 is inserted into the movable groove 4, it drives the elastic limiting member to slide to the limit position and be in a compressed state. The elastic limiting member releases the blockage of the communication between the receiving groove 10 and the annular groove 9. The fixed block 7 abuts and lapped with the plurality of balls 11, forcing the balls 11 to move in the receiving groove 10 and partially located in the annular groove 9. When the fixed block 7 is completely located in the movable groove 4, the first annular groove 8 communicates with the plurality of receiving grooves 10. Release the elastic limiting member, and the elastic limiting member slides to the initial position and resets to the natural state. The elastic limiting member blocks the communication between the receiving groove 10 and the annular groove 9. The balls 11 are partially located in the first annular groove 8 and cannot enter the annular groove 9, that is, the fixed block 7 cannot exit the movable groove 4, and the sliding rod 5 cannot slide, so as to lock the sliding rod 5. On the contrary, drive the elastic limiting member to slide to the limit position and be in a compressed state. The elastic limiting member releases the blockage of the communication between the receiving groove 10 and the annular groove 9. The sliding rod 5 slides to the initial position and drives the fixed block 7 to move out of the movable groove 4 together, forcing the balls 11 to move in the receiving groove 10 and partially located in the annular groove 9. Then, release the elastic limiting member, and the elastic limiting member slides to the initial position and resets to the natural state. The elastic limiting member blocks the communication between the receiving groove 10 and the annular groove 9, and the balls 11 cannot enter the annular groove 9, so as to unlock the sliding rod 5.

[0037] As Figure 5 shown, in some embodiments, the elastic limiting member includes an annular plate 12 that is slidably arranged in the annular groove 9 and abuts and lapped with the plurality of balls 11. An extrusion spring 13 is arranged between the annular plate 12 and the annular groove 9, and both ends of the extrusion spring 13 are fixedly connected to the annular groove 9 and the annular plate 12 respectively;

[0038] Referring to the above, in the initial state, the compression spring 13 is in its natural state, the ring plate 12 is in its initial position and blocks the connection between the receiving groove 10 and the annular groove 9. When the fixed block 7 is inserted into the movable groove 4, it drives the ring plate 12 to slide to the extreme position, the compression spring 13 is compressed, and the ring plate 12 releases the blockage of the connection between the receiving groove 10 and the annular groove 9. When the fixed block 7 is completely located within the movable groove 4, the ring plate 12 is released, the compression spring 13 returns to its natural state, and the ring plate 12 slides back to its initial position and blocks the connection between the receiving groove 10 and the annular groove 9. Conversely, when unlocking the sliding rod 5, it drives the ring plate 12 to slide to the extreme position, the compression spring 13 is compressed, the ring plate 12 releases the blockage of the connection between the receiving groove 10 and the annular groove 9, the sliding rod 5 slides back to its initial position and drives the fixed block 7 to move out of the movable groove 4 together, and then the ring plate 12 is released, the compression spring 13 returns to its natural state, and the ring plate 12 slides back to its initial position and blocks the connection between the receiving groove 10 and the annular groove 9.

[0039] As Figure 5 shown, in some embodiments, the receiving groove 10 includes a first tapered section, a cylindrical section, and a second tapered section that are connected in sequence. The first tapered section is connected to the annular groove 9, and the second tapered section is connected to the movable groove 4;

[0040] Referring to the above, when the ball 11 moves within the receiving groove 10, through the combined action of the first tapered section, the cylindrical section, and the second tapered section, the ball 11 cannot completely exit the receiving groove 10.

[0041] Embodiment Three

[0042] Embodiment Three proposes another structure of the locking portion and the locking mechanism on the basis of Embodiment One.

[0043] As Figures 6 - 8 shown, in some embodiments, the locking portion includes a positioning plate 14 provided on the sliding rod 5 and in abutting connection with the fixed cylinder 3. The positioning plate 14 is fixed on the sliding rod 5. A connecting rod 15 is provided on the positioning plate 14. The connecting rod 15 is fixed on the positioning plate 14. A limiting rod 16 is slidably provided on the connecting rod 15 and a tension spring 17 is provided between them. The sliding direction of the limiting rod 16 is perpendicular to the sliding direction of the sliding rod 5. The two ends of the tension spring 17 are respectively fixedly connected to the limiting rod 16 and the connecting rod 15. The free end of the limiting rod 16 is provided with a tapered block 18. The tapered block 18 is fixedly connected to the limiting rod 16. A through hole 19 is provided on the tapered block 18. The through hole 19 is opened along the length direction of the sliding rod 5;

[0044] Referring to the above, in the initial state, the sliding rod 5 is located at the initial position, the positioning plate 14 is far away from the fixed cylinder 3, the limiting rod 16 is located at the initial position, the tension spring 17 is in the natural state. When the sliding rod 5 slides to the limit position, the positioning plate 14 abuts and laps with the fixed cylinder 3, acts on the through hole 19 through the locking mechanism and locks the sliding rod 5. The sliding rod 5 cannot slide, and the positioning plate 14 cannot move away from the fixed cylinder 3. On the contrary, acts on the through hole 19 through the locking mechanism and unlocks the sliding rod 5. The sliding rod 5 slides to the initial position and drives the positioning plate 14 to move away from the fixed cylinder 3.

[0045] As Figure 9 shown, in some embodiments, the locking mechanism includes a second annular groove 20 formed on the fixed cylinder 3. The cross-sectional structure of the second annular groove 20 is V-shaped. A moving disk 21 is slidably arranged on the fixed cylinder 3 and a return spring 22 is arranged between them. The moving disk 21 slides along the length direction of the fixed cylinder 3. The two ends of the return spring 22 are respectively fixedly connected to the moving disk 21 and the fixed cylinder 3. A convex block 23 that is inserted and matched with the through hole 19 is arranged on the moving disk 21. The convex block 23 is fixedly arranged on the moving disk 21;

[0046] Referring to the above, in the initial state, the moving disk 21 is located at the initial position, the return spring 22 is in the natural state. When the sliding rod 5 slides to the limit position, the positioning plate 14 abuts and laps with the fixed cylinder 3, driving the moving disk 21 to slide to the limit position. The return spring 22 is compressed. The tapered block 18 abuts and laps with the fixed cylinder 3. Through the transition of the inclined plane, the tapered block 18 and the limiting rod 16 are forced to move to the limit position together. The tension spring 17 is stretched. Then the tension spring 17 returns to the natural state. The tapered block 18 and the limiting rod 16 move to the initial position together. The tapered block 18 is located in the second annular groove 20. Then release the moving disk 21. The return spring 22 returns to the natural state. The moving disk 21 slides to the initial position, driving the convex block 23 to be inserted into the through hole 19. Due to the block of the convex block 23, the tapered block 18 cannot exit the second annular groove 20, that is, the sliding rod 5 cannot slide, so as to lock the sliding rod 5. On the contrary, drive the moving disk 21 to slide to the limit position. The return spring 22 is compressed, driving the convex block 23 to exit the through hole 19. The sliding rod 5 slides to the initial position and drives the positioning plate 14 to move away from the fixed cylinder 3. The tapered block 18 exits the second annular groove 20 and drives the limiting rod 16 to move to the limit position together. The tension spring 17 is stretched. Then the tension spring 17 returns to the natural state. The tapered block 18 and the limiting rod 16 move to the initial position together. Then release the moving disk 21. The return spring 22 returns to the natural state. The moving disk 21 slides to the initial position.
