[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] See also Figure 1-10The utility model provides a hydrogenation gun support of a hydrogenation machine, comprising a square plate 2, two sets of locking components 3 for fixing the hydrogenation gun 1 and a control box 6, a handle 11 is provided on the outer side of the hydrogenation gun 1, a lever 12 for controlling the opening and closing of the valve of the hydrogenation gun 1 is connected to the right side of the hydrogenation gun 1 and located above the handle 11, an upper limit ring 13 is provided on the outer side of the hydrogenation gun 1 and located above the lever 12, and a lower limit ring 14 is provided on the outer side of the hydrogenation gun 1 and located below the handle 11. The square plate 2 is fixed by bolts Fixed on the right side of the hydrogenator, the upper end of the square plate 2 is fixedly connected with the top plate 21, the upper end opening of the hydrogenation gun 1 abuts against the lower surface of the top plate 21, two sets of locking components 3 are distributed up and down on the right side of the square plate 2, and a clamping member 4 for fixing the lever 12 is connected to the right side of the square plate 2 and located in the middle of the two sets of locking components 3, and two sets of elastic sensing members 5 are connected to the middle of the two sets of locking components 3 and located on one side of the clamping member 4, and the control box 6 is located on the side of the elastic sensing member 5 away from the clamping member 4 and is fixedly connected to the square plate 2;

[0032] The locking assembly 3 includes a fixed seat 31, two sets of movable plates 32 and two sets of opposite arc-shaped snap rings 33. The fixed seat 31 is fixed to the right side of the square plate 2 by bolts. The two sets of movable plates 32 are slidably connected to the inside of the fixed seat 31. The right side of the movable plate 32 is fixedly connected with a connecting block 321. The two sets of arc-shaped snap rings 33 are fixedly connected to the right side of the connecting block 321 on the corresponding side. The two sets of arc-shaped snap rings 33 are away from the side of the connecting block 321 to form a mounting groove for inserting the hydrogenation gun 1. The upper limit ring 13 abuts against the bottom of the two sets of arc-shaped snap rings 33 located above The lower limit ring 14 abuts against the two groups of arc-shaped snap rings 33 located below. The outer sides of the two groups of movable plates 32 are fixedly connected with two groups of springs 1 34. One end of the spring 1 34 away from the movable plate 32 abuts against the inner wall of the fixed seat 31. The inner side wall of the fixed seat 31 is fixedly connected with an electric push rod 35, and the electric push rod 35 is located on the inner side of the two groups of springs 1 34. The telescopic end of the electric push rod 35 abuts against the outer side of one group of movable plates 32. The two groups of movable plates 32 are connected by a synchronous member 36, and the electric push rod 35 is electrically connected to the control box 6.

[0033] The elastic sensing member 5 includes a sleeve 51, which is fixedly connected to the right side of the square plate 2. A contact sensor 52 is fixedly connected inside the sleeve 51. A trigger rod 53 for triggering the contact sensor 52 is elastically connected to the right side of the sleeve 51. The contact sensor 52 is electrically connected to the control box 6.

[0034] Through the setting of the locking assembly 3 of the utility model, the staff can easily insert the hydrogenation gun 1 into the inner side of the two groups of arc-shaped snap rings 33 and obtain elastic fixation. When placing the hydrogenation gun 1, the staff only needs to press the hydrogenation gun 1 from one side of the installation groove to the inner side of the two groups of arc-shaped snap rings 33 (in this process, it is necessary to ensure that the upper limit ring 13 and the lower limit ring 14 are placed between the two groups of locking assemblies 3 located above and below, so as to prevent the hydrogenation gun 1 from sliding up and down after placement). When the two groups of arc-shaped snap rings 33 are subjected to the extrusion force from the hydrogenation gun 1, they will move to both sides synchronously and compress the spring 1 34. When the hydrogenation gun 1 completely enters the inner side of the two groups of arc-shaped snap rings 33, the spring 1 34 recovers its deformation and resets the two groups of arc-shaped snap rings 33. At this time, the hydrogenation gun 1 is elastically fixed to the inner side of the two groups of arc-shaped snap rings 33.

[0035] During the placement of the hydrogenation gun 1, as the hydrogenation gun 1 is inserted, the left side wall of the hydrogenation gun 1 will contact the trigger rod 53 and gradually squeeze the trigger rod 53 in the direction of the sleeve 51. When the hydrogenation gun 1 is inserted into place, the trigger rod 53 will simultaneously trigger the contact sensor 52 (when the contact sensor 52 is triggered, it proves that the hydrogenation gun 1 has been fully inserted into the inner side of the two sets of arc-shaped clamping rings 33), and then the contact sensor 52 will transmit the signal to the control box 6, and then the control box 6 will control the telescopic end of the electric push rod 35 to extend and abut against one side of one set of movable plates 32. At this time, the position of the movable plate 32 is fixed, thereby preventing the movement of the arc-shaped clamping ring 33, so that the hydrogenation gun 1 is firmly fixed inside the two sets of arc-shaped clamping rings 33 (at this time, no matter how the hydrogenation gun 1 is pulled, the arc-shaped clamping ring 33 will not move because the movable plate 32 is fixed, thereby maintaining the safe fixed state of the hydrogenation gun 1).

[0036] Specifically, when the hydrogenation gun 1 is inserted into place, the upper opening of the hydrogenation gun 1 will abut against the lower surface of the top plate 21. The function of the top plate 21 is to protect the upper opening of the hydrogenation gun 1 from dirt and impurities, thereby protecting the upper opening of the hydrogenation gun 1 from the influence of the external environment.

[0037] In addition, ordinary push buttons, fingerprint buttons or password buttons can be installed on the surface of the control box 6. These buttons are used to control the retraction of the telescopic end of the electric push rod 35, thereby releasing the abutment restriction of the telescopic end of the electric push rod 35 on one set of movable plates 32. When the staff needs to take out the hydrogenation gun 1, they need to press the button first, and the telescopic end of the electric push rod 35 retracts, thereby releasing the abutment restriction of the telescopic end of the electric push rod 35 on one set of movable plates 32 (once the telescopic end of the electric push rod 35 retracts, the movable plate 32 can slide freely. This means that the movable plate 32 no longer fixes the position of the hydrogenation gun 1, creating conditions for taking out the hydrogenation gun 1). At this time, the staff can pull the hydrogenation gun 1 outward to conveniently take out the hydrogenation gun 1 (the specific operation is: pull the hydrogenation gun 1 to the right, and the arc-shaped clamping ring 33 will slide to both sides by itself after being subjected to external force and compress the spring 1 34, so that the hydrogenation gun 1 can be conveniently taken out). This increases the safety of the hydrogenation gun 1 , not only allowing the hydrogenation gun 1 to be safely removed when needed, but also ensuring that the hydrogenation gun 1 will not be misoperated or damaged by unauthorized personnel outside of normal operation.

[0038] Furthermore, a rubber pad 331 is bonded to the inner side of the arc-shaped clamping ring 33 .

[0039] The provision of the rubber pad 331 enables the hydrogenation gun 1 to be more firmly fixed between the two sets of arc-shaped clamping rings 33 when clamped. The rubber material itself has a certain viscosity and elasticity, which can increase the friction between the hydrogenation gun 1 and the arc-shaped clamping ring 33 to prevent the hydrogenation gun 1 from accidentally falling due to vibration or movement.

[0040] Furthermore, the synchronizer 36 includes an upper rack 361, a lower rack 362 and a gear 363. The upper rack 361 is fixedly connected to the upper surface of one group of movable plates 32 through a top block 322, and the lower rack 362 is fixedly connected to the lower surface of another group of movable plates 32 through a top block 322. The gear 363 is rotatably connected to the inside of the fixed base 31. The upper rack 361 and the lower rack 362 are respectively meshed on the upper and lower sides of the gear 363, and the upper rack 361 and the lower rack 362 are both slidably connected to the inside of the fixed base 31.

[0041] When one set of movable plates 32 moves, the upper rack 361 will be driven to move through the top block 322. Since the upper rack 361 is meshed with the upper side of the gear 363, the gear 363 will rotate accordingly. The rotation of the gear 363 will cause the lower rack 362 and the upper rack 361 to undergo opposite displacement changes, which means that when one set of movable plates 32 moves in a certain direction, the other set of movable plates 32 will be indirectly driven to move in the opposite direction. The function of the synchronizer 36 is that the upper rack 361 and the lower rack 362 always change displacement at the same distance, thereby indirectly enabling the two sets of arc-shaped retaining rings 33 located in the same set of locking assemblies 3 to be opened to both sides or moved toward the middle synchronously, which ensures that the hydrogenation gun 1 is subjected to uniform force during the clamping process and will not be unstable or deflected, thereby improving the safety and stability of the operation.

[0042] Furthermore, the upper rack 361 and the lower rack 362 are fixedly connected to a connecting seat 364 on one side surface away from the gear 363, and pulleys 365 are rotatably connected to both sides of the connecting seat 364. The upper and lower sides of the interior of the fixed seat 31 are fixedly connected to slide rails 366, and the pulley 365 is slidably connected to the interior of the slide rails 366.

[0043] During the sliding process, the upper rack 361 and the lower rack 362 drive the pulley 365 to slide inside the slide rail 366 through the connecting seat 364. The setting of the slide rail 366 enables it to accurately guide and limit the movement range of the pulley 365, ensuring the accuracy of the movement of the upper rack 361 and the lower rack 362. The self-rotation of the pulley 365 reduces the sliding resistance of the upper rack 361 and the lower rack 362, making their movement smoother and more efficient.

[0044] Furthermore, the clamping member 4 includes a mounting plate 41 and two groups of clamping rods 42 . The mounting plate 41 is fixed to the right side of the square plate 2 by screws. The two groups of clamping rods 42 are fixedly connected to the right side of the mounting plate 41 . The lever 12 is located between the two groups of clamping rods 42 .

[0045] When the hydrogenation gun 1 is inserted into place, the lever 12 will be inserted between the two groups of clamping rods 42, so that the lever 12 is limited by the upper and lower positions of the two groups of clamping rods 42 and cannot rotate, which means that the lever 12 cannot control the valve of the hydrogenation gun 1 to open. Only when the hydrogenation gun 1 is removed can the lever 12 be used to control the valve to open, which further ensures the safety of the use of the hydrogenation gun 1 and ensures that there will be no safety hazards caused by operating errors or instability during the placement process.

[0046] Furthermore, a second spring 54 is sleeved on the outer side of the contact sensor 52 , and two ends of the second spring 54 are respectively in contact with the inside of the sleeve 51 and a side of the trigger rod 53 close to the sleeve 51 .

[0047] During the process of inserting the hydrogenation gun 1 into the inner side of the two sets of arc-shaped clamping rings 33, the second spring 54 is gradually compressed. When the hydrogenation gun 1 is taken out, the second spring 54 recovers its deformation and squeezes the trigger rod 53 out by elastic force, thereby preparing for the next insertion of the hydrogenation gun 1.

[0048] Furthermore, a protective cover 7 is fixedly connected to the outer side of the square plate 2 and located on the outer side of the hydrogenation gun 1 .

[0049] The protective cover 7 can protect the hydrogenation gun 1 and the support of the hydrogenation gun 1 from damage and influence of the external environment.

[0050] The above are only preferred implementations of the present invention and are not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
