Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation, and more specifically to a spring-type car top fixing frame. Background Art

[0002] At present, elevators can be seen in major shopping malls, companies, residential areas and hospitals. With the increase in the number of elevators, elevator safety accidents have gradually increased. Although elevator safety issues have been increasingly taken seriously this year, elevator accidents are still common. There are many reasons for elevator accidents. Failed elevator maintenance and elevator overloading are the root causes of frequent elevator accidents. In order to reduce the occurrence of elevator accidents, elevator companies have better designs for elevator security facilities. However, there are still shortcomings in the current elevators, especially the elevator top fixing devices, the firmness and stability of which need to be optimized.

[0003] The existing patent is a car top fixing frame for a passenger elevator, and the patent authorization number is CN 212769251 U. All fixing devices can be installed on the mounting plate first, and then the mounting plate is fixed to the car top with bolts, which not only simplifies the car top fixing device, but also greatly facilitates future maintenance.

[0004] However, in the patent authorization number CN 212769251 U, bolts and nuts are used to connect and fix the bottom plate and the top of the car body. Since the elevator car will vibrate during operation, the vibration is transmitted to the bolts for a long time, which can easily cause the nuts to loosen, thereby affecting the overall installation stability of the fixing frame. Therefore, we propose a spring-type car top fixing frame to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a spring-type car top fixing bracket, which can utilize the elastic force of the return spring to make the top of the movable seat engage with the plug-in hole, thereby facilitating the installation of the mounting plate and effectively preventing the mounting plate from loosening due to vibration generated during the operation of the elevator car, thereby ensuring the overall installation stability of the fixing bracket.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A spring-type car top fixing frame comprises an elevator car and a roller, wherein the top of the elevator car is symmetrically provided with grooves, and the inner wall of the groove is symmetrically provided with guide grooves;

[0010] A movable seat is installed inside the guide groove, and a guide slope is arranged on the top of the movable seat. A guide column head which is slidably connected to the guide groove is fixedly connected to the side wall of the movable seat.

[0011] A return spring is also installed on the inner side of the groove;

[0012] A mounting plate is installed above the elevator car, and strip holes are provided at positions corresponding to the grooves. A plugging hole connected to the strip holes is provided at the end of the mounting plate, and the plugging hole is engaged with the top of the movable seat.

[0013] Furthermore, a positioning column is fixedly connected to the top edge of the elevator car, and a plurality of the positioning columns are symmetrically arranged, and the top ends of the plurality of positioning columns are all arranged in a conical structure.

[0014] Furthermore, a positioning hole is provided at a portion of the mounting plate corresponding to the positioning column, and an inner diameter of the positioning hole is matched with an outer diameter of the positioning column.

[0015] Furthermore, one end of the return spring is connected to the movable seat, and the other end of the return spring is connected to the inner wall of the groove.

[0017] Furthermore, a handle is fixedly connected to the top end of the movable seat located on one side of the guiding inclined surface, and the handle protrudes from the top opening of the strip-shaped hole.

[0018] Furthermore, the top of the movable seat is gap-matched with the plug-in hole.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this solution, the edge of the bottom of the strip hole is abutted against the guiding inclined surface of the top of the movable seat. Under the action of pressure, the guide column head slides in cooperation with the guide groove, so that the movable seat moves inside the groove and compresses and deforms the return spring. When the plug-in hole corresponds to the top of the movable seat, the elastic force of the return spring is used to make the top of the movable seat engage with the plug-in hole. This facilitates the installation of the mounting plate and effectively prevents the mounting plate from loosening due to vibration generated during the operation of the elevator car, thereby ensuring the overall installation stability of the fixed frame.

[0022] (2) This solution utilizes the positioning column to correspond to the positioning hole, and the top end of the positioning column is set in a conical structure, which is conducive to the docking between the positioning column and the positioning hole. The docking between the positioning column and the positioning hole is conducive to the correspondence between the movable seat and the plug-in hole, thereby facilitating the fixation of the mounting plate.
