Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 7 As shown, the utility model provides a standard gas distribution instrument, including:

[0033] An outer box 1, a box cover 2 is hingedly connected to the rear side of the top of the outer box 1, and a gas distribution instrument body 3 is fixedly sleeved inside the outer box 1;

[0034] The supporting mechanism 4 is arranged on the right side of the box cover 2;

[0035] A locking mechanism 5, which is arranged on the right side of the outer box 1;

[0036] Among them, the supporting mechanism 4 includes a slide groove 401, the number of which is two, and the two slide grooves 401 are respectively opened at the left and right ends of the outer box 1, and the bottom ends of the two slide grooves 401 are respectively movably sleeved with sliders 402, and the outer surface of the slider 402 is fixedly installed with a movable block 403, and the outer surface of the movable block 403 is movably connected to the outer surface of the outer box 1. There are two movable blocks 403, and the bottom ends of the rear ends of the two movable blocks 403 are respectively hinged with support rods 404, and the outer surface of the support rods 404 is movably connected to the outer surface of the outer box 1, and the internal movability sleeve of the rear end of the support rods 404 is connected with a fixed rod 405, and the outer surface of the fixed rod 405 is fixedly connected to the outer surface of the box cover 2, and the support rod 404 will move the movable block 403.

The existence of the slide groove 401 and the slider 402 will limit the movement of the movable block 403. With the mutual cooperation of the movable block 403, the box cover 2 is supported, thereby preventing the box cover 2 from being accidentally closed after it is opened.

[0056] When the lock 403 is unlocked, the locking nut 504 is unlocked, and the locking nut 504 is unlocked, so that the lock 403 is unlocked.

[0057] Then the operator can connect the gas supply pipe and the gas distributor body 3 and operate the gas distributor body 3 through the operation screen 6. When the gas distributor is used, the operator pulls the connecting rod 17, so that the connecting rod 17 moves upward with the round rod 16, so that the round block 14 moves upward with the clamping rod 13 along the inner surface of the mounting plate 11 and compresses the second spring 15 until the clamping rod 13 and the clamping groove 12 are separated. Then the operator pushes the connecting rod 17, so that the mounting plate 11 moves with the cleaning plate 10 along the outer surface of the operation screen 6, thereby completing the cleaning of the outer surface of the operation screen 6. When the cleaning is completed, the operator resets the cleaning plate 10.
