Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a wall panel structure for retrofitting old elevators. Background Technology

[0002] As the market demand for elevator renovation continues to grow, renovation solutions are becoming more flexible and diverse. Replacing all old elevators during renovation avoids compatibility issues for new elevator manufacturers, but it results in high costs and long renovation cycles. However, by conducting safety assessments of old elevators by elevator safety assessment agencies, parts that meet safety standards or are still usable can be retained, except for those that must be scrapped or replaced. For example, if the elevator car is still usable, only the wall panels that experience severe wear and tear need to be replaced.

[0003] Currently, elevator car wall panels on the market are usually composed of multiple panels spliced ​​together, and the panels are connected to each other by multiple bolts. The bolts are usually located on the outside of the car. For example, Chinese patent application number 201810107075.8 discloses an elevator car wall including two front wall panels, a lintel connected to the upper part of the two front wall panels, and three inner wall panels connected in sequence. Each inner wall panel includes a middle wall panel and two side wall panels connected to both sides of the middle wall panel. A connecting strip is connected between the front wall panel and the adjacent side wall panel, and between adjacent side wall panels. The connection between the front wall panel, the connecting strip, the side wall panel, and the middle wall panel is a snap-fit ​​connection in the vertical direction. The upper and lower ends of the middle wall panel, the side wall panel, and the front wall panel are threaded to the top and bottom of the car, respectively. In situations where the elevator shaft is narrow and a person cannot stand between the car wall and the shaft wall, this elevator allows for quick and convenient installation or removal of a particular wall panel without having to remove all the wall panels and the car top.

[0004] However, connecting wall panels with snap-fit ​​fasteners, where the hooks are integrally molded with the panels, requires replacing wall panels with corresponding fasteners during old staircase renovations. This makes it inconvenient to selectively replace individual old staircase wall panels, increasing the cost of renovations. Therefore, we need to propose a wall panel structure for old staircase renovations that improves compatibility with existing staircase wall panels, allowing for targeted replacement of individual wall panels and reducing renovation costs. Utility Model Content

[0005] The purpose of this utility model is to provide a wall panel structure for the renovation of old stairs, which can improve the compatibility with the old stairs wall panels, thereby enabling the targeted replacement of individual wall panels in the old stairs, reducing the cost of old stairs renovation, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wall panel structure for retrofitting old elevators, comprising a wall panel component installed on the car floor, the wall panel component consisting of a rear panel, two side panels and a front panel, the front panel, side panels and rear panel being connected to the car floor via pressure strips, and the side panels being connected to the front panel and the side panels being connected to the rear panel via a reinforcement mechanism with magnetic adsorption effect, the reinforcement mechanism being a separate unit.

[0007] Preferably, the front panel, side panel and rear panel all include a panel, and the upper and lower ends of the panel are provided with mounting holes for connecting with the pressure strip.

[0008] Preferably, both sides of the panel and both ends of the pressure strip are provided with bevels, and the bevels on two adjacent panels are matched with the bevels on two adjacent pressure strips.

[0009] Preferably, the pressure strip is arranged in the shape of a chamfer, and one side of the pressure strip has a plurality of round holes at equal intervals for connecting with the panel, and the other side of the pressure strip has a plurality of elongated holes at equal intervals for connecting with the car floor.

[0010] Preferably, the width of the pressure strip is the same as the thickness of the panel, and a decorative strip is fixed to one side of the pressure strip inside the car.

[0011] Preferably, the reinforcement mechanism includes an L-shaped plate and a straight plate made of metal, and a magnet is embedded on the side of the straight plate opposite to the L-shaped plate, and the magnet is magnetically attracted to the straight plate.

[0012] Preferably, both the straight plate and the L-shaped plate are provided with multiple screw holes, and the edge of the panel is provided with threaded blind holes corresponding to the screw holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model mainly uses the cooperation between the pressure strip and the wall panel components to replace one or more of the front panel, side panel and rear panel according to actual usage needs. Through the transition of the pressure strip, the compatibility of the front panel, side panel and rear panel is improved, making it easier to match with the original wall panels in the old ladder and reducing the cost of old ladder renovation.

[0015] 2. This utility model connects the side panel and the front panel, as well as the side panel and the rear panel, through a split-type reinforcement mechanism. The reinforcement mechanism has a magnetic adsorption effect, which ensures the connection force between adjacent panels while allowing the reinforcement mechanism to be separately installed on the original wall panel of the old ladder, thus improving the versatility of panel installation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a wall panel structure for retrofitting an old elevator, including a wall panel component installed on the car floor 7. The wall panel component consists of a rear panel 3, two side panels 1, and a front panel 2. The front panel 2, side panels 1, and rear panel 3 are all connected to the car floor 7 via pressure strips 6. The side panels 1 and the front panel 2, as well as the side panels 1 and the rear panel 3, are connected by a reinforcement mechanism 5 with a magnetic adsorption effect. The reinforcement mechanism 5 is a split type. Through the cooperation of the pressure strips 6 and the wall panel component, one or more of the front panel 2, side panels 1, and rear panel 3 can be replaced according to actual usage needs. The conversion of the pressure strips 6 improves the compatibility of the front panel 2, side panels 1, and rear panel 3, making it easier to match with the original wall panels in the old elevator and reducing the cost of retrofitting the old elevator.

[0023] The front panel 2, side panel 1 and rear panel 3 all include a panel 11. The upper and lower ends of the panel 11 are provided with mounting holes 12 for connecting with the pressure strip 6. The mounting holes 12 facilitate the connection between the panel 11 and the pressure strip 6. The round holes 61 on the pressure strip 6 are correspondingly set with the mounting holes 12 on the panel 11, which improves the firmness of the connection between the pressure strip 6 and the panel 11.

[0024] Both sides of the panel 11 and both ends of the pressure strip 6 are provided with bevels. The bevels on two adjacent panels 11 are matched with the bevels on two adjacent pressure strips 6, so that the front panel 2, side panel 1 and rear panel 3 can be vertically spliced ​​between panels 11 when splicing, which is suitable for the renovation of old elevator cars.

[0025] The front panel 2 is configured with two panels 11 according to the actual installation requirements of the elevator car. A channel for the installation of the elevator car door is left between the two panels 11. A baffle 4 is fixed at one end of the channel of the panel 11. The baffle 4 provides a certain installation space for the elevator car door, which facilitates the installation of the elevator car door.

[0026] The pressure strip 6 is arranged in the shape of a c. Multiple round holes 61 for connecting with the panel 11 are equally spaced on one side of the pressure strip 6, and multiple elongated holes 62 for connecting with the car floor 7 are equally spaced on the other side of the pressure strip 6. The bottom of the pressure strip 6 has continuous elongated holes 62, which can directly adapt to the connection holes of the old floor plate to the greatest extent. The upper opening of the pressure strip 6 is adapted to the standard elevator wall panel. Through the conversion of the pressure strip 6, the trouble of straight wall panel design is eliminated.

[0027] The width of the pressure strip 6 is the same as the thickness of the panel 11. A decorative strip is fixed on one side of the pressure strip 6 inside the car, so that the side wall of the pressure strip 6 can be flush with the side wall of the panel 11, increasing the aesthetics of the assembled wall panel structure. The decorative strip can be installed in two ways: one is a relatively economical option, which is to install a stainless steel plate on the inside of the pressure strip 6 and use it directly as a skirting board; the other is a more upscale decoration option, which is to install marble paving with the same thickness as the pressure strip 6.

[0028] The reinforcement mechanism 5 includes an L-shaped plate 51 and a straight plate 52 made of metal. A magnet 53 is embedded on the side of the straight plate 52 opposite to the L-shaped plate 51. The magnet 53 is magnetically attracted to the straight plate 52, and the reinforcement mechanism 5 has a magnetic attraction effect. A slot is opened on the straight plate 52 for the magnet 53 to be embedded. The magnet 53 is fixed inside the slot. The magnetic attraction between the magnet 53 and the L-shaped plate 51 is used to improve the connection force between the panels 11. While ensuring the connection force between adjacent panels 11, the reinforcement mechanism 5 can be separately installed on the original wall panel of the old ladder, improving the versatility of the panel 11 installation.

[0029] Both the straight plate 52 and the L-shaped plate 51 are provided with multiple screw holes 54. The edge of the panel 11 is provided with threaded blind holes corresponding to the screw holes 54. Through the cooperation of the screw holes 54 and the threaded blind holes, the straight plate 52 or the L-shaped plate 51 can be installed on the panel 11 according to the actual use requirements. When compatible with the original wall panels of the old elevator car, it is only necessary to open the threaded blind holes on the original wall panels, and then use threads to install the straight plate 52 or the L-shaped plate 51 on the original wall panels, so that the straight plate 52 or the L-shaped plate 51 can be attracted to the L-shaped plate 51 or the straight plate 52 on the panel 11 in this application, thereby increasing the firmness of the connection between the original wall panels and the panel 11. The L-shaped plate 51 and the straight plate 52 need to be installed on one panel 11 according to the actual car height requirements.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
