[0014] Beneficial Effects

[0015] The utility model provides a protective device for a gas valve steel rod, which has the following beneficial effects:

[0016] 1. The protective device for gas valve steel rods is provided with an adjustment mechanism. When in use, according to the length of the gas valve steel rod to be stored and protected, a hexagonal wrench can be inserted into the hexagonal groove to drive the adjusting threaded sleeve to rotate. Since the adjusting threaded sleeve and the adjusting sliding hole are threadedly connected, the adjusting threaded sleeve moves back and forth along the outer side of the adjusting sliding hole. The adjusting threaded sleeve drives the telescopic sliding sleeve to move back and forth along the inside of the telescopic sliding groove to be adjusted to a suitable position through the protective rear cover plate, so that the storage cavity of the device is adapted to the length of the gas valve steel rod, and the gas valve steel rod can be placed in the device for storage and protection. The protective rear cover plate is slidably connected to the inside of the two limiting sliding holes through two limiting sliding rods, thereby enhancing the connection with the protective base and improving the stability of the device structure. The above operation is simple and practical, so that the device can store and protect gas valve steel rods of different lengths, thereby improving the applicability of the device.

[0017] 2. The protective device for the gas valve steel rod has a positioning mechanism, and the protective top cover is fixed to the protective base by the magnetic force between the positioning iron sheet and the positioning magnet block, so that it is convenient for the staff to open and close the protective top cover to take out or put in the gas valve steel rod inside the equipment, thereby improving the convenience of using the equipment.

[0018] 3. A protective device for a gas valve steel rod is provided with a first rubber pad and a second rubber pad. When the device is placed in a specified position, the protective base and the protective rear cover are in contact with the contact surface through the first rubber pad and the second rubber pad respectively, which not only provides protection for the protective base and the protective rear cover, but also enhances the friction between the contact surface, so that the device can be placed more stably and the service life of the device is increased.
