Description
Technical Field
[0001] The utility model relates to the technical field of safety blocking devices, in particular to a safety blocking device for an elevator. Background Art
[0002] An elevator is a type of transportation equipment that transports pedestrians or goods vertically. The elevator serves buildings of specified floors. A vertical lift elevator has a car that runs between at least two rows of vertical rigid guide rails or guide rails with an inclination angle of less than 15°, which is convenient for passengers to enter and exit or load and unload goods. In order to maximize the use of space, home elevators generally adopt a backpack structure. The interior space of this type of elevator is relatively small. Unlike high-rise elevators, there is not enough space to install conventional safety protection devices composed of speed limiters, tensioning wheels, and safety clamp lifting mechanisms. A Chinese patent with publication number CN209097977U discloses a safety blocking device for a home elevator, wherein the home elevator has a guide rail, a guide rail base plate, and a car frame. The guide rail is erected on the guide rail base plate, and the car frame runs on the guide rail. The safety blocking device includes an upper component, a lower component, and a trigger component.
[0003] With respect to the disclosed technology, in order to ensure the normal use of the existing home elevators when they are in use, the home elevators need to be inspected and maintained regularly. During the elevator maintenance process, the elevator car needs to be stopped at a specified position and the elevator needs to be stopped. However, during the elevator maintenance process, since home elevators do not have sufficient space like high-rise elevators to install conventional safety protection devices such as speed limiters, tensioners, and safety clamp lifting mechanisms, it is impossible to ensure that the elevator will not be displaced when it stops running. The elevator car may accidentally fall, causing considerable physical and mental harm to the maintenance staff.
[0004] For this purpose, a safety blocking device for an elevator is proposed. Utility Model Content
[0005] The purpose of the utility model is to solve the problem that because a home elevator does not have sufficient space like a high-rise elevator to install conventional safety protection devices composed of structures such as a speed limiter, a tensioner pulley and a safety clamp lifting mechanism, it is impossible to ensure that the elevator will not be displaced when it stops running, and the elevator car may accidentally fall, causing considerable physical and mental harm to the maintenance staff. The utility model provides a safety blocking device for the elevator.
[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0007] A safety blocking device for an elevator comprises an elevator back wall, a placement groove is provided on the surface of the elevator back wall, a connecting component for elevator bottom blocking is arranged on the inner wall of the placement groove, a rotating component for moving the elevator bottom blocking member out of the placement groove is arranged on the inner wall of the placement groove, a diagonal brace component is arranged on the surface of the rotating component, and a buffer component for elevator bottom blocking is arranged on the top surface of the diagonal brace component.
[0008] Furthermore, the connection assembly includes a fixing block, the inner wall of the placement groove is overlapped with the fixing block, the surface of the fixing block is provided with fixing bolts, and the fixing bolts are connected to the inner wall of the placement groove, and the surface of the fixing block is fixedly connected with a connecting piece.

[0025] like Figure 3 As shown, the rotating assembly 4 includes a motor 401, the top surface of the inner wall of the placement slot 2 is fixedly connected to the motor 401, the output end of the motor 401 is fixedly connected to the connecting rod 402, the bottom surface of the connecting rod 402 is fixedly connected to the rotating rod 403, and the rotating rod 403 is rotatably connected to the connecting piece 303, the bottom surface of the inner wall of the placement slot 2 is fixedly connected to the bearing 404, and the inner ring of the bearing 404 is fixedly connected to the rotating rod 403; specifically, the output end of the motor 401 drives the connecting rod 402 to rotate, and the connecting rod 402 drives the rotating rod 403 to rotate with the cooperation of the bearing 404, at this time the rotating rod 403 drives the diagonal brace assembly 5 to leave the interior of the placement slot 2, and rotates the diagonal brace assembly 5 and the buffer assembly 6 out of the interior of the placement slot 2.
[0026] like Figure 2 , Figure 3 As shown, the diagonal brace assembly 5 includes a mounting plate 501, the surface of the rotating rod 403 is fixedly sleeved with the mounting plate 501, and the mounting plate 501 overlaps with the connecting piece 303, the bottom surface of the mounting plate 501 is fixedly connected with a first hinge seat 502, the surface of the first hinge seat 502 is hinged with a diagonal brace rod 503, the surface of the rotating rod 403 is fixedly connected with a second hinge seat 504, and the second hinge seat 504 is hinged with the diagonal brace rod 503; specifically, the first hinge seat 502, the diagonal brace rod 503 and the second hinge seat 504 support the mounting plate 501, the first hinge seat 502 and the second hinge seat 504 facilitate the connection and fixation of the diagonal brace rod 503 between the mounting plate 501 and the rotating rod 403, so that the mounting plate 501 can support the elevator car more firmly.
[0027] like Figure 2As shown, the buffer assembly 6 includes a lower fixed sleeve 601, the top surface of the mounting plate 501 is fixedly connected with the lower fixed sleeve 601, the bottom surface of the inner wall of the lower fixed sleeve 601 is fixedly connected with a spring 602, the end of the spring 602 away from the lower fixed sleeve 601 is fixedly connected with an upper fixed sleeve 603, and the top surface of the upper fixed sleeve 603 is fixedly connected with a buffer block 604; specifically, when the elevator car is descending and hovering, the bottom of the elevator car will first contact the top surface of the buffer block 604, at which time the upper fixed sleeve 603 at the bottom of the buffer block 604 drives the spring 602 to be squeezed and contracted, and the spring 602 slows down the descending impact force of the elevator car, thereby reducing the impact force of the elevator car on the diagonal bracing assembly 5, and thus the impact force of the elevator when descending and hovering will not damage the safety blocking device of the elevator.
[0028] like Figure 3 As shown, the fixing block 301 is rectangular and is made of metal.

The mounting plate 501 is supported. When the elevator car is descending and hovering, the bottom of the elevator car will first contact the top surface of the buffer block 604. At this time, the upper fixing sleeve 603 at the bottom of the buffer block 604 drives the spring 602 to be squeezed and contracted. The spring 602 reduces the downward impact force of the elevator car, thereby reducing the impact force of the elevator car on the diagonal brace assembly 5. At this time, the diagonal brace assembly 5 and the buffer assembly 6 support the bottom of the elevator car, thereby avoiding the problem that the home elevator car may descend during maintenance. The safety blocking device is also embedded in the back wall 1 of the elevator and does not occupy the space inside the elevator shaft.
