Locking reset mechanism

Abstract

The invention discloses a turnover mechanism, in particular relates to a locking reset mechanism. The locking reset mechanism comprises a power rod, a support rack, a base plate and a cover plate, wherein one end of the cover plate is hinged with the base plate, an upper die is arranged at the other end of the cover plate, a lower die corresponding to the upper die is arranged on the base plate, the power rod is hinged onto the support rack, a stepping plate is arranged at one end of the power rod, a row of meshing teeth is arranged at the other end of the power rod, a rotary gear is arranged on the support rack, a pin shaft is arranged between the rotary gear and the support rack, the gear is fixed on the pin shaft, the pin shaft is rotatably connected onto the support rack, a second gear for transmission is arranged between the meshing teeth and the rotary gear, a first shaft gear is arranged on the base plate, the pin shaft passes through the support rack and is fixedly connected with the first shaft gear, and a limiting mechanism for limiting the rotational angle of the first shaft gear is arranged on the base plate. By the locking reset mechanism, the technical defect of inconvenience in manual operation existing in the prior art is overcome, and the locking reset mechanism which is suitably used for fine production of a manual product is provided.

Description

technical field [0001] The invention relates to a linkage mechanism, in particular to a locking reset mechanism. Background technique [0002] At present, the wall switches on the market are usually switches with a seesaw swing at both ends of the button. When the switch is turned on and off, the position of the switch seesaw is different, so that it cannot be integrated with the wall and affects the house. The integrity of the interior. In order to solve the above-mentioned technical problems, a switch capable of automatic reset has appeared in the prior art, such as Chinese Patent No. CN201020158209.8, authorized announcement number. CN201638727, the authorized announcement date is November 17, 2010, the invention patent titled "a mechanical self-resetting switch", and its technical solution is "a mechanical self-resetting switch, including a shell and a conductive sheet, inside the shell There are installation grooves for accommodating conductive sheets respectively, an...

Problems solved by technology

Although the above scheme can realize the reset of the flap, its structure is slightly complicated, and the cost and circuit failure rate are high.

[0003] If the reset method of electric trigger is not used, but the reset effect of the limit position is realized by mechanical spring, there will be the following technical problems: the force applied to the spring in actual use is uncontrollable, and it is very likely to exceed the maximum bearing capacity of the spring Force, causing damage to the spring, once the applied force exceeds the bearing capacity of the spring, not only the spring will be unusable, but also may cause incalculable loss to the parts connected by the spring
