Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide shoes, in particular to a guide shoe for a household elevator. Background Art

[0002] The guide shoe is a sliding nylon block between the elevator guide rail and the car, called a guide shoe. It can fix the car on the guide rail so that the car can only move up and down. There is also an oil cup on the upper part of the guide shoe to reduce the friction between the shoe lining and the guide rail. Patent No. CN202022575247.X discloses a guide shoe for a home elevator. The first shoe lining is in sliding contact with the moving section. In this way, there is sliding friction between the first shoe lining and the guide rail, which increases the contact area between the contact surface of the first shoe lining and the guide rail, plays a better clamping role for the guide rail, and improves the stability of the car when moving. However, since home elevators are not often used, sometimes the staff will not be asked to maintain the elevator guide shoe according to the corresponding time. If there is a large wear between the shoe lining and the guide rail inside the elevator guide shoe and the user does not notice it, the guide shoe will directly rub against the guide rail. The rubbing between the two is prone to wear and has a certain impact on the guide shoe itself. In severe cases, it will directly cause the shoe seat to malfunction and damage. To this end, we propose a guide shoe for a home elevator. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a guide shoe for a household elevator.

[0004] The technical solution adopted by the utility model to solve the technical problem is a guide shoe for a household elevator, comprising a shoe seat and a guide rail, wherein the outer wall surface of the shoe seat is integrally constructed with a support plate for support, and the support plate has two groups, a screw rod for adjustment is slidably mounted on the outer periphery of the support plate, and the screw rod has multiple groups, a support plate for support is integrally constructed on the outer end surface of the screw rod, and a spring located on the outer periphery of the screw rod is arranged between the support plate and the support plate, and the spring has multiple groups, and a shock-absorbing cylinder for buffering is arranged between the support plate and the support plate, and the shock-absorbing cylinder has multiple groups;

[0005] A supporting bracket is assembled between the two groups of support plates by bolts, and a gear for connection is rotatably installed inside the bracket, and there are multiple groups of gears. The outer peripheral side surfaces of the guide rails are integrally constructed with racks meshing with the gears.

[0006] By adopting the above technical solution, when the elevator guide shoe and the guide rail inside the elevator shaft slide against each other, the gear on the inner side of the bracket installed on the surface of the shoe seat can mesh with the rack on the surface of the guide rail, and the gear can mesh and step along the rack conveniently, so that the shoe seat can slide and move along the guide rail more stably. At the same time, when the shoe lining on the inner side of the shoe seat is greatly worn, the meshing movement between the gear and the guide rail can also provide certain support performance for the shoe seat, so that the elevator can move along the guide rail more stably, and it is convenient to reduce the damage of the elevator guide shoe itself.

[0007] When the gear meshes and steps along the rack on the guide rail surface, the spring between the support plate on the shoe seat surface and the support plate facilitates pushing the support plate, so that the support plate drives the screw to slide on the outside of the support plate. At the same time, the support plate facilitates pushing the bracket, so that the bracket can more stably drive the gear and the rack to mesh with each other and step along the rack. At the same time, the shock-absorbing cylinder between the support plate and the support plate facilitates assistance, thereby providing a certain buffering performance for the bracket, so that when the elevator shakes, it can provide a certain buffering force and reduce the damage caused by scratches between the guide rail and the shoe seat.

[0008] Specifically, a nut body located outside the support plate is threadedly installed on the outer periphery of the screw rod, and there are multiple groups of nut bodies.

[0009] By adopting the above technical solution, the nut body and the screw are threadedly connected to each other, which makes it easy to adjust the length of the screw between the support plate and the support plate, thereby facilitating the regulation of the elasticity of the spring between the support plate and the support plate, so that the spring can provide a buffering force when the bracket and the gear and rack are meshed with each other in the subsequent process.

[0010] Specifically, both side end surfaces of the outer circumference of the gear are integrally constructed with disc bodies located on both sides of the rack.

[0011] By adopting the above technical solution, the discs on both sides of the gear are located on both sides of the rack, which makes it easy to reduce the misalignment between the two when the gear runs on the rack surface.

[0012] Specifically, the outer wall surface of the support plate is provided with sliding holes for connection, and there are multiple groups of sliding holes. The outer wall surface of the support plate is integrally constructed with sliding strips that are slidably connected to the sliding holes.

[0013] By adopting the above technical solution, the slide bar slides inside the slide hole, which is convenient for improving the stability of the support plate when sliding between the two groups of support plates, and is convenient for reducing the situation where the support plate swings randomly when in use.

[0014] Specifically, inclined blocks for auxiliary support are welded between the support plate and the shoe seat, and there are multiple groups of inclined blocks.

[0015] By adopting the above technical solution, the inclined block facilitates improving the stability of the two groups of support plates on the outer side of the boot seat, so that the support plates can be used more stably.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of support plates, guide rails, racks, brackets and gears. When the guide shoe of the elevator slides against the guide rail inside the elevator shaft, the gear on the inner side of the bracket installed on the surface of the shoe seat can mesh with the rack on the surface of the guide rail, and the gear can easily mesh and step along the rack, so that the shoe seat can slide and move along the guide rail more stably. At the same time, when the shoe lining on the inner side of the shoe seat is greatly worn, the meshing movement between the gear and the guide rail can also provide certain support performance for the shoe seat, so that the elevator can move along the guide rail more stably and it is convenient to reduce the damage of the elevator guide shoe itself.

[0018] 2. The technical solution of the present application is designed with a screw, a support plate, a spring and a shock-absorbing cylinder. When the gear meshes and steps along the rack on the surface of the guide rail, the spring between the support plate on the surface of the shoe seat and the support plate facilitates pushing the support plate, so that the support plate drives the screw to slide on the outside of the support plate. At the same time, the support plate facilitates pushing the bracket, so that the bracket can more stably drive the gear and the rack to mesh with each other and step along the rack. At the same time, the shock-absorbing cylinder between the support plate and the support plate facilitates assistance, thereby providing a certain buffering performance for the bracket, so that when the elevator shakes, it can provide a certain buffering force and reduce the damage caused by scratches between the guide rail and the shoe seat.
