[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, a simple locking device for hydraulic gun liquid supply includes a magnetic locking component and a sliding switch component; the magnetic locking component includes two sets of mutually symmetrical lock cores 1, and magnets 2 are glued and fixed on the opposite surfaces of the lock cores 1, and the two sets of lock cores 1 can be adsorbed and fixed by the magnets 2; the sliding switch component includes a positioning seat 3, a slide rod 4 is fixed on the positioning seat 3, a slide seat 5 is slidably mounted on the slide rod 4, and two mutually symmetrical switch lock rods 6 are fixedly connected to the slide seat 5; the rod head of the switch lock rod 6 is set at an angle, and a guide groove 7 for use with the switch lock rod 6 is opened through the main body of the lock core 1; the hydraulic gun liquid supply A simple locking device is used on a hydraulic gun, which primarily includes a gun body 11, a handle 12, and a grip 13. The lock core 1 in the magnetic locking assembly is installed through openings on both sides of the gun body 11, which are not located within the fluid supply chamber. The sliding switch assembly is removably secured to the outer shell of the gun body 11 via a positioning seat 3 secured with screws. When the switch lock rod 6 is not inserted into the insertion groove 7, the two sets of lock cores 1 are attracted by the magnet 2 and locked. When the switch lock rod 6 is fully inserted into the insertion groove 7, the two sets of lock cores 1 are completely separated and unlocked. This device is installed on the gun body 11 of the hydraulic gun. The magnetic locking assembly and the sliding switch assembly work together to easily lock the handle 12, saving effort in actual use.

[0038] like Figure 7 As shown, a smooth steel ball 8 is welded and fixed in the guide groove 7. In order to reduce the friction of the switch lock rod 6 sliding in the guide groove 7, by installing the steel ball 8, the friction between the switch lock rod 6 and the steel ball 8 will be smaller, and it will be more labor-saving when operating the switch lock rod 6 to move.

[0039] like Figure 8 As shown, the surface where the slide bar 4 meets the slide seat 5 is provided with damping. In order to increase the friction between the slide bar 4 and the slide seat 5, the surface of the slide bar 4 is provided with damping, thereby improving the stability of the slide bar 4 after sliding.

[0040] like Figure 8As shown, a finger ring 9 is fixedly connected to the middle of the slide 5. The inner diameter of the finger ring 9 is large enough for the operator's thumb to fit into it. To facilitate the movement of the slide 5, the operator can insert his thumb into the finger ring 9 after holding the handle, so that the handle 12 can be locked at any time.

[0041] like Figure 8 As shown, a latch 10 is removably inserted into the end of the slide bar 4 to prevent the slide 5 from disengaging. The latch 10 and the slide bar 4 are assembled in an interference fit. To prevent the slide 5 from disengaging, the latch 10 is provided to prevent it from disengaging. The latch 10 can be removed later to facilitate replacement of the entire slide 5.

[0042] The working principle of this utility model:

[0043] When the hydraulic gun needs remote fluid supply, the staff needs to press the handle 12 for a long time. The staff can hold the grip 13 and insert the thumb into the finger ring 9, so as to lock the handle 12 at any time.

[0044] In normal use, the slide 5 is pushed by the thumb to move, so that the switch lock rod 6 of the slide 5 is inserted into the guide groove 7. At this time, the two sets of lock cylinders 1 are completely separated to be in the unlocked state, and the handle 12 can be pressed at will. Figures 5 and 6 When the handle 12 needs to be locked, the slide 5 is pushed by the thumb to move, so that the switch lock rod 6 of the slide 5 is disengaged from the guide groove 7. At this time, the two sets of lock cores 1 are adsorbed by the magnet 2 to be in a locked state, as shown. Figures 3 and 4 As shown, the two sets of lock cores 1 can completely lock the handle 12, which saves the staff more effort.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
