[0039] As Figures 1-3As shown, the utility model provides a kind of hydrogenation gun, including gun body 100, still including first limiting element 200 and limiting sleeve 300.
[0040] The side wall of the first end of gun body 100 is provided with a first mounting hole 110 extending in the radial direction, and the first limiting element 200 is movably arranged in the first mounting hole 110. The limiting sleeve 300 is sleeved on the gun body 100, and the limiting sleeve 300 is movably connected with the gun body 100, so that the limiting sleeve 300 can move along the axial direction of the gun body 100. Wherein, the movable connection mentioned here can be movable connection, such as sliding connection, and can also be threaded connection.
[0041] Among them, the outer side wall of hydrogenation port 800 is correspondingly provided with a first limiting groove 810 matched with the first limiting element 200, and the inner side wall of limiting sleeve 300 is correspondingly provided with a first avoiding groove 310 matched with the first limiting element 200.
[0042] The first limiting element 200 has a first position and a second position, and the limiting sleeve 300 has a third position and a fourth position.
[0043] Among them, in working state, the first limiting element 200 is placed in the first position, and the limiting sleeve 300 is placed in the third position, so that the first side of the first limiting element 200 is located in the first limiting groove 810, and the second side is in contact with the inner side wall of the limiting sleeve 300. Through the cooperation of the first limiting groove 810 and the first limiting element 200, the hydrogenation port 800 is limited, and then the hydrogenation port 800 is locked, so that the hydrogenation port 800 cannot be pulled out of the gun body 100. At the same time, since the second side of the first limiting element 200 is in contact with the inner side wall of the limiting sleeve 300, the first side of the first limiting element 200 cannot move out of the first limiting groove 810, so as to effectively limit the hydrogenation port 800.
[0044] In non-working state, the first limiting element 200 is placed in the second position, and the limiting sleeve 300 is placed in the fourth position, so that the second side of the first limiting element 200 is located in the first avoiding groove 310, and the first side is located outside the first limiting groove 810, so as to smoothly pull out the hydrogenation port 800 from the gun body 100.
[0045] Specifically, when the first limiting element 200 is in the first position and the limiting sleeve 300 is in the third position, the first avoiding slot 310 is staggered with the first limiting element 200, and at the same time, the first side of the first limiting element 200 is located outside the inner side wall of the gun body 100, so that the first side of the first limiting element 200 can be matched with the first limiting slot 810 (i.e., when the hydrogen inlet 800 is inserted into the preset position, so that the first limiting slot 810 corresponds to the first limiting element 200, the first side of the first limiting element 200 is located in the first limiting slot 810), and the second side of the first limiting element 200 is located outside the outer side wall of the gun body 100 or flush with the outer side wall of the limiting sleeve 300, so that the second side of the first limiting element 200 can be in contact with the inner side wall of the limiting sleeve 300, thereby preventing the first limiting element 200 from moving from the first position to the second position.
[0046] When the first limiting element 200 is in the second position and the limiting sleeve 300 is in the fourth position, the first avoiding slot 310 corresponds to the first limiting element 200, the second side of the first limiting element 200 is located in the first avoiding slot 310, and the first side of the first limiting element 200 is retracted to the inner side wall of the gun body 100, so that the first side of the first limiting element 200 cannot be matched with the first limiting slot 810 (i.e., the first limiting element 200 is separated from the first limiting slot 810), thereby achieving the purpose of pulling out the hydrogen inlet 800 from the gun body 100.
[0047] The hydrogen gun provided by the embodiment has a simple structure and a reasonable design. The first limiting element 200 is in the second position and the limiting sleeve 300 is in the fourth position, so as to achieve the purpose of assembling or disassembling the hydrogen inlet 800. The first limiting element 200 is in the first position and the limiting sleeve 300 is in the third position, so as to achieve the purpose of limiting and locking the hydrogen inlet 800. The operation is convenient, and the hydrogen inlet 800 is convenient to assemble and disassemble.
[0048] Preferably, the inner side wall of the first limiting slot 810 and / or the first side of the first limiting element 200 are provided with a first guide surface, which is an arc surface or an inclined surface, so that the hydrogen inlet 800 can apply a force to the first limiting element 200 through the first guide surface, thereby driving the first limiting element 200 from the first position to the second position.
[0049] Preferably, the inner side wall of the first avoiding slot 310 and / or the second side of the first limiting element 200 are provided with a second guide surface, which is an arc surface or an inclined surface, so that the limiting sleeve 300 can apply a force to the first limiting element 200 through the second guide surface, thereby driving the first limiting element 200 from the second position to the first position.
[0050] As shown in FIG. 1, Figure 1 ,3 The first elastic element 400 is connected with the gun body 100 and the limiting sleeve 300 at two ends respectively, and in a natural state, the first elastic element 400 exerts elastic force on the limiting sleeve 300, so that the limiting sleeve 300 has a tendency to move from the fourth position to the third position.
[0051] Specifically, the first elastic element 400 can be an elastic component capable of exerting elastic force on the limiting sleeve 300, such as a gas spring, a hydraulic spring, a rubber spring, a spring, etc. In the embodiment, the first elastic element 400 is a spring.
[0052] When the hydrogenation port 800 is assembled, first, the limiting sleeve 300 is moved to the fourth position, so that the first avoiding slot 310 corresponds to the first limiting element 200, thereby enabling the hydrogenation port 800 to drive the first limiting element 200 from the first position to the second position; then the hydrogenation port 800 is inserted into the gun body 100, and in the process of inserting the hydrogenation port 800, the hydrogenation port 800 exerts force on the first limiting element 200, so that the first limiting element 200 moves from the first position to the second position, thereby achieving the purpose of enabling the hydrogenation port 800 to be smoothly inserted into the gun body 100; then the limiting sleeve 300 is loosened, and under the action of the elastic force of the first elastic element 400, the limiting sleeve 300 moves from the fourth position to the third position, and in this process, the limiting sleeve 300 exerts force on the first limiting element 200, so that the first limiting element 200 moves from the second position to the first position, thereby achieving the purpose of limiting and locking the hydrogenation port 800, and at the same time, when the limiting sleeve 300 moves to the third position, the inner side wall of the limiting sleeve 300 abuts against the second side of the first limiting element 200, thereby keeping the first limiting element 200 in the first position, and further achieving the purpose of effectively limiting and locking the hydrogenation port 800.
[0053] When the hydrogenation port 800 needs to be disassembled, first, the limiting sleeve 300 is moved to the fourth position, so that the first avoiding slot 310 corresponds to the first limiting element 200, and then the hydrogenation port 800 is pulled out, and the hydrogenation port 800 exerts force on the first limiting element 200, thereby driving the first limiting element 200 from the first position to the second position, and further achieving the purpose of smoothly pulling out the hydrogenation port 800.
[0054] The hydrogenation gun with the structure is simple in structure, reasonable in design, and convenient for assembling and disassembling the hydrogenation port 800.
[0055] As Figure 1 , 3As shown, the inner side wall of the limiting sleeve 300 is provided with a guide sliding groove 330, and the outer side wall of the cavity is correspondingly provided with a guide portion 130 matched with the guide sliding groove 330. In the working state, the guide sliding groove 330 cooperates with the guide portion 130, so as to limit and guide the movement direction of the limiting sleeve 300.
[0056] As shown in Figure 1 , 3 , the second limiting element 700 is further included.
[0057] The pushing sleeve 500 is arranged in the gun body 100 and located at the first end of the gun body 100, and the pushing sleeve 500 is movably connected with the gun body 100.
[0058] The two ends of the second elastic element 600 are connected with the gun body 100 and the pushing sleeve 500 respectively, and in the natural state, the second elastic element 600 exerts an elastic force on the pushing sleeve 500, so that the pushing sleeve 500 has a tendency to move away from the second end of the gun body 100.
[0059] Specifically, the second elastic element 600 can be an elastic component capable of exerting an elastic force on the pushing sleeve 500, such as a gas spring, a hydraulic spring, a rubber spring, a spring, etc. In this embodiment, the second elastic element 600 is a spring.
[0060] In use, after the limiting sleeve 300 is moved to the fourth position, the second elastic element 600 exerts an elastic force on the hydrogenation port 800 through the pushing sleeve 500, so as to push the hydrogenation port 800 out of the gun body 100, thereby achieving the purpose of facilitating the disassembly of the hydrogenation port 800.
[0061] As shown in Figure 1 , 3 , the second limiting element 700 is further included. The side wall of the first end of the gun body 100 is provided with a second mounting hole 120, the second mounting hole 120 is located on the side of the first mounting hole 110 facing the second end of the gun body 100, and the second mounting hole 120 is a through hole. The second limiting element 700 is arranged in the second mounting hole 120, and the second limiting element 700 is movably connected with the gun body 100.
[0062] The pushing sleeve 500 is correspondingly provided with a second limiting groove 510 matched with the second limiting element 700, and the limiting sleeve 300 is correspondingly provided with a second avoiding groove 320 matched with the second limiting element 700.
[0063] The second limiting element 700 has a fifth position and a sixth position.
[0064] In the working state, the second limiting element 700 is placed in the fifth position, and the limiting sleeve 300 is placed in the third position, so that the first side of the second limiting element 700 is located in the second limiting groove 510, and the second side is in contact with the inner side wall of the limiting sleeve 300. Through the cooperation of the second limiting groove 510 and the second limiting element 700, the pushing sleeve 500 is limited, so that the pushing sleeve 500 cannot exert force on the hydrogenation port 800. At the same time, since the second side of the second limiting element 700 is in contact with the inner side wall of the limiting sleeve 300, the first side of the second limiting element 700 cannot move out of the second limiting groove 510, thereby achieving the purpose of effectively limiting the pushing sleeve 500.
[0065] In the non-working state, the second limiting element 700 is placed in the sixth position, and the limiting sleeve 300 is placed in the fourth position, so that the second side of the second limiting element 700 is located in the second limiting groove 510, and the first side is located outside the second limiting groove 510, thereby achieving the purpose that the pushing sleeve 500 can exert force on the hydrogenation port 800.
[0066] Specifically, when the second limiting element 700 is in the fifth position and the limiting sleeve 300 is in the third position, the second limiting element 700 is offset from the second limiting groove 320, and the first side of the second limiting element 700 is located outside the inner side wall of the gun body 100, so that the first side of the second limiting element 700 can cooperate with the first limiting groove 810 (i.e., when the pushing sleeve 500 moves to the preset position, the second limiting groove 510 corresponds to the second limiting element 700, and the first side of the second limiting element 700 is located in the second limiting groove 510), and the second side of the second limiting element 700 is located outside the outer side wall of the gun body 100 or flush with the outer side wall of the limiting sleeve 300, so that the second side of the second limiting element 700 can be in contact with the inner side wall of the limiting sleeve 300, thereby preventing the second limiting element 700 from moving from the fifth position to the sixth position.
[0067] When the second limiting element 700 is in the sixth position and the limiting sleeve 300 is in the fourth position, the second limiting groove 320 corresponds to the second limiting element 700, and the second side of the second limiting element 700 is located in the second limiting groove 320, while the first side of the second limiting element 700 is retracted inside the inner side wall of the gun body 100, so that the first side of the second limiting element 700 cannot cooperate with the second limiting groove 510 (i.e., the second limiting element 700 is separated from the second limiting groove 510), thereby achieving the purpose that the pushing sleeve 500 can exert force on the hydrogenation port 800.
[0068] Preferably, the inner side wall of the second position avoiding groove 320 and / or the first side of the second limiting element 700 is provided with a third guide surface which is an arc surface or an inclined surface, so that the push sleeve 500 can apply a force to the second limiting element 700 through the third guide surface, thereby driving the second limiting element 700 to move from the fifth position to the sixth position.
[0069] The inner side wall of the second position avoiding groove 320 and / or the second side of the second limiting element 700 is provided with a fourth guide surface which is an arc surface or an inclined surface, so that the limiting sleeve 300 can apply a force to the second limiting element 700 through the fourth guide surface, thereby driving the second limiting element 700 to move from the sixth position to the fifth position.
[0070] As shown in the drawings, Figure 2 In the present embodiment, the first limiting element 200 is arc-shaped, and the cross section of the first limiting element 200 is circular. The first limiting element 200 of this structure saves space, and because the cross section is circular, it has a guide arc surface by itself, which is convenient for manufacturing.
[0071] As shown in the drawings, Figure 1 , 3 The second limiting element 700 is spherical. The second limiting element 700 of this structure saves space, and because the cross section is circular, it has a guide arc surface by itself, which is convenient for manufacturing.
