[0015] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0016] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0017] like Figure 1-3As shown, a device for preventing the dragging of a hydrogenation gun at a hydrogenation station includes a hydrogenation tank 1, an anti-drag assembly 2, a hydrogenation pipe 3, and a hydrogenation gun 4. A storage slot 5 is defined on one side of the hydrogenation tank 1, and the anti-drag assembly 2 is mounted within the storage slot 5. One end of the hydrogenation pipe 3 is connected to the storage slot 5 of the hydrogenation tank 1, and the other end of the hydrogenation pipe 3 is connected to the hydrogenation gun 4. A fixing block 16 is mounted on the end of the hydrogenation pipe 3 connected to the hydrogenation tank 1 to secure the pipe joint of the hydrogenation pipe 3.

[0018] The anti-pull assembly 2 includes a fixed frame 6 installed on both sides of the placement groove 5 and a first pulley 7, a second pulley 8, and a third pulley 9 installed on the fixed frame 6. The first pulley 7 is located above the second pulley 8 and the third pulley 9. The hydrogenation pipe 3 passes through the second pulley 8, the first pulley 7, and the third pulley 9 in sequence and is connected to the hydrogenation gun 4. When the hydrogenation gun 4 is hydrogenating, the handheld hydrogenation gun 4 pulls out the hydrogenation pipe 3. Under the action of the first pulley 7, the second pulley 8, and the third pulley 9, the pulling force acting on the pipe joint of the hydrogenation pipe 3 is dispersed, solving the problem that the pipe joint of the hydrogenation pipe 3 is damaged due to strong pulling and hydrogen will leak at high speed. A chute 10 is provided on both sides of the fixed frame 6. The chute 10 is slidably connected to the first slider 11 and the second slider 12. The first slider 11 is connected to the first pulley 7, and the second slider 12 is connected to the second pulley 8 and the third pulley 9; the first slider 11 and the second slider 12 are connected by a connector. The connecting member includes a fixed seat 13, a first spring 14 and a second spring 15. The fixed block 16 is installed in the middle of the fixed frame 6. One end of the first spring 14 abuts against the fixed seat 13, and the other end of the first spring 14 abuts against the first slider 11; one end of the second spring 15 abuts against the fixed seat 13, and the other end of the second spring 15 abuts against the second slider 12. When the hydrogenation tube 3 is pulled, the hydrogenation tube 3 acting on the first pulley 7, the second pulley 8 and the third pulley 9 drives the first slider 11 and the second slider 12 to move toward each other under the action of the slide groove 10, and the first spring 14 and the second spring 15 are in a compressed state; when the hydrogenation of the hydrogenation tube 3 is completed, the hydrogenation tube 3 is released, and under the action of the elastic potential energy of the first spring 14 and the second spring 15, the first slider 11 and the second slider 12 move backwards to retract the hydrogenation tube 3, thereby dispersing the pulling force acting on the pipe joint of the hydrogenation tube 3 and solving the problem of the pipe joint of the hydrogenation tube 3 being damaged due to strong pulling; at the same time, the hydrogenation tube 3 will not be knotted when used for a long time.

[0019] The working principle of this embodiment is as follows: when connecting two air ducts, when the hydrogenation gun 4 is performing hydrogenation, the hydrogenation tube 3 is pulled out by holding the hydrogenation gun 4, and the hydrogenation tube 3 acting on the first pulley 7, the second pulley 8 and the third pulley 9 drives the first slider 11 and the second slider 12 to move toward each other under the action of the slide 10, and the first spring 14 and the second spring 15 are in a compressed state; when the hydrogenation of the hydrogenation tube 3 is completed, the hydrogenation tube 3 is released, and under the action of the elastic potential energy of the first spring 14 and the second spring 15, the first slider 11 and the second slider 12 move backwards to retract the hydrogenation tube 3, and the working process is as follows.
