Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1, the internal switch of the internet of things table includes: the motor 2 is arranged in the shell 1, a worm 5 is arranged on an output shaft of the motor 2, a rotating shaft 3 and a rotating shaft are rotationally arranged in the shell 1, the rotating shaft 3 and the rotating shaft are respectively arranged at two sides of the worm 5 (according to the illustration in fig. 1, the rotating shaft 3 and the rotating shaft are respectively arranged at the upper side and the lower side of the worm 5, and the positions of the rotating shaft 3 and the rotating shaft are reasonably arranged to reduce the occupied space); the rotating shaft 3 is fixedly sleeved with a worm wheel 4 and a gear, the worm wheel 4 is meshed with a worm 5, the rotating shaft is fixedly sleeved with a sector gear 6, the sector gear 6 is meshed with the gear, and the sector gear 6 is provided with a deflector rod 14;

referring to fig. 1, a bow 11 is provided in a housing 1, a movable contact 10 is provided on one side of the bow 11 facing a sector gear 6, a stationary contact 8 attached to the movable contact 10 is provided in the housing 1, the stationary contact 8 is located between the movable contact 10 and the sector gear 6 (the positions of the stationary contact 8 and the movable contact 10 are optimized, and the space occupied by the stationary contact is reduced, so that the whole volume of the built-in switch is reduced), a pushing block 7 is slidably provided in the housing 1 (capable of moving up and down in the housing 1), the pushing block 7 is connected with an end (right end) of the bow 11, the pushing block 7 moves to drive the end of the bow 11 to move, a slot is provided on a left side wall of the pushing block 7, and a deflector rod 14 is inserted in the slot;
