Description

Technical Field

[0001] The invention relates to the technical field of plastic bases, in particular to a thermoplastic plastic base. Background Art

[0002] The plastic base of the air switch is an important part of ensuring the safe and stable operation of the electrical system. It is carefully made of high-quality plastic material and has excellent insulation performance and good heat resistance. This plastic base not only provides a stable installation foundation for the air switch, but also effectively isolates the current to prevent dangerous situations such as leakage and short circuit. In the complex and changeable electrical environment, it always maintains reliable performance with its high strength and anti-aging characteristics. For example, in a high temperature environment, the plastic base will not deform; in a humid environment, it will not affect its insulation effect. Whether it is household electricity or industrial electricity scene, the plastic base of the air switch is silently guarding the safety of the circuit.

[0041] Working principle: When the air switch needs to be installed, align the guides on the upper and lower surfaces of the air switch with the guide slots 11 for installation, and at this time, the slot on one side of the air switch fits with the protrusion 15. After the air installation is completed, the translation plate 21 can be pressed to allow the movable plate 22 to move downward to disengage the card block 221 from the inside of the card slot 122. Then, the position of the translation plate 21 can be selected according to the length of the air switch. When the position of the translation plate 21 is selected, release the pressing force to allow the card block 221 to be re-engaged in the card slot 122 to fix the clamping component 2. In order to facilitate the installation of the air switch, the clamping plate 23, which is restricted to a horizontal state by the torsion spring 213, can simultaneously press the pressing plate 2373 to allow the movable rod 237 to bring the fixed block 2371 back to the inside of the storage slot 234, and then the clamping plate 23 can be rotated to make it vertical, and then the pressing plate 2373 can be released to allow the fixed block 237 1 is inserted into the fixing groove 111, so that the air switch is clamped inside the base body 1. When the air switch is clamped, the knob 183 can be rotated to rotate the rotating rod 18 with the ellipsoid 181, so that the ellipsoid 181 in the horizontal state is rotated into a vertical state, so as to push up the vertical plate 16. Because the groove on one side of the air switch is also provided with grooves at the top and bottom, and the grooves are adapted to the vertical plate 16, when the air switch is installed and the ellipsoid 181 is in the numerical state, the vertical plate 16 will be pushed into the groove to further stabilize the air switch and the base body 1, and the side rod 184 after rotation will separate the closed clamping block 191 against the triangular block 185 on the outer surface, so that the side rod 184 enters the clamping hole 192, so that the clamping block 191 fixes the side rod 184, and the clamping block 191 stabilizes the side rod 184, thereby improving the stability of the installation of the base body 1 and the clamping component 2.
