Embodiment Construction
[0022] In order to explain the overall concept of the present invention more clearly, the following will be described in detail by way of examples in combination with the accompanying drawings.
[0023] It should be noted that many specific details have been set forth in the following description so as to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, therefore, the protection scope of the present invention is not limited by the following limitations of the specific embodiments disclosed.
[0024] In addition, in the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal" ", "Top", "Bottom", "Inner", "Outer", "Axial", "Radial", "Circumferential" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the dra...

The invention relates to the field of domestic indoor elevators, in particular to a safety protection locking mechanism for an indoor elevator. The safety protection locking mechanism comprises an elastic plate, a lifting assembly and two locking pieces, wherein the middle section of the elastic plate is connected with the top of alift car; the lifting assembly comprises two reversing pulleys respectively arranged at the two ends of the elastic plate, a reel and a cable wound on the reel; the cable reverses from the reversing pulleys and extends upwards, the cable applies upward force to the end part of the elastic plate from the reversing pulleys to bend and deform the elastic plate, and the two ends of the elastic plate move upwards; the two locking pieces are respectively arranged at the two ends of the elastic plate, and each locking piece has a first state for stopping the movement of the lift car and a second state for releasing; and when the end part of the elastic plate moves downwards beyond a set threshold value, the elastic plate triggers each locking piece to switch from the second state to the first state. According to the locking mechanism, when the cable is disconnected, the locking pieces are triggered by elastic deformation of the elastic plate to brake and lock the lift car, and the problems in the prior art are effectively solved.
Description
technical field [0001] The invention relates to the field of domestic indoor elevators, in particular to a safety protection locking mechanism for indoor elevators. Background technique [0002] As a small indoor elevator for family use, the home indoor elevator is especially widely used in villas with 2-3 floors. Considering that the space occupied by the domestic indoor elevator cannot be too large, a kind of vertical guide rail without a shaft is generally arranged between the floors of the domestic indoor elevator, and the driving device of the indoor elevator moves together with the car of the indoor elevator. Specifically, a motor is used to drive a reel to retract and release two cables wound on two pulleys to realize the lifting of the domestic indoor elevator. In the existing domestic indoor elevator, the car cannot be effectively braked when the cable is disconnected, which not only has the danger of the car falling drunk, but also damages the components of the in...
