Anti-friction side plate for roller shutter door

Abstract

This utility model relates to the field of roller shutter door technology, specifically to an anti-friction side plate for roller shutter doors. It includes a mounting base with a sliding groove inside. A movable plate slides within the groove, and several bearings are located at the bottom of the movable plate. An anti-friction component is installed between two adjacent bearings at one end of the movable plate. By installing the anti-friction component between adjacent bearings, this utility model ensures that during the movement of the movable plate, only the steel balls first slide and contact the top wall of the groove, while the bearings do not contact the top wall of the groove. This significantly improves the smoothness of the movable plate's left and right movement, effectively preventing jamming and sticking. Furthermore, by arranging bearings and anti-friction components opposite to each other on the movable plate, this utility model further adapts to large roller shutter doors. When the movable plate slides within the groove, the steel balls on both sides contact the top and bottom walls of the groove respectively, ensuring operational stability and reducing the problem of jamming in large roller shutter doors.

Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically to an anti-friction side plate for roller shutter doors. Background Technology

[0002] A roller shutter door is a door composed of multiple articulated movable door panels connected together. It is usually made of materials such as color steel plate and stainless steel. It can be opened and closed by manually or by motor driving the door panels to roll up and down along the track.

[0003] Modern roller shutters typically have movable side panels at both ends to prevent scratches. As the roller shutter rises and falls, the movable side panels automatically follow, keeping the door in a straight line and preventing friction. The movable side panels usually have about four bearings. When the bearings slide in the fixed slide groove, the side of the bearing will rub against the inside of the fixed slide groove, affecting the left and right movement of the movable side panels. This causes the roller shutter to shake and jam when rising and falling. When the friction is severe, it may stop working, thus affecting the performance of the roller shutter. Utility Model Content

[0004] The purpose of this utility model is to provide a reasonably designed anti-friction side plate for roller shutter doors, which can solve the above-mentioned defects and deficiencies of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mounting base, a sliding groove is provided in the mounting base, a movable plate is slidably arranged in the sliding groove, a plurality of bearings are provided at the bottom of the movable plate, and an anti-friction component is provided between two adjacent bearings at one end of the movable plate.

[0006] Preferably, the anti-friction component includes a fixed block connected to the movable plate, and a steel ball is provided on the fixed block, the steel ball slidingly contacting the top wall of the groove.

[0007] Preferably, the movable plate is provided with bearings and anti-friction components facing each other.

[0008] Preferably, all of the bearings are made of rust-resistant material.

[0009] The beneficial effects of this utility model after adopting the above structure are: 1. By setting anti-friction components between adjacent bearings, the steel balls will slide and contact the inner top wall of the chute first during the movement of the moving plate, while the bearings will not contact the inner top wall of the chute. Therefore, the smoothness of the moving plate when moving left and right can be greatly improved, effectively preventing the occurrence of jamming, sluggishness and other phenomena.

[0010] 2. This utility model, by setting bearings and anti-friction components opposite to each other on the moving plate, and the bearings symmetrically arranged on the moving plate to form a support system with uniform force on both sides, can effectively disperse the weight of the roller shutter door and the impact force during operation, further adapting to large roller shutter doors. Subsequently, when the moving plate slides in the slide groove, the steel balls on both sides roll into contact with the inner top wall and inner bottom wall of the slide groove respectively. With the use of double-sided bearings, the stability during operation is ensured, reducing the problem of large roller shutter doors easily getting stuck. Attached Figure Description

[0013] 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.

[0014] Example 1: like Figures 1-5As shown, the present invention proposes an anti-friction side plate for a roller shutter door, which includes a mounting base 1, a sliding groove 2 provided in the mounting base 1 to provide guidance, a movable plate 3 slidably provided in the sliding groove 2, and a number of bearings 4 provided at the bottom of the movable plate 3. In this solution, 6 bearings 4 are installed, which has better load-bearing performance and makes left and right movement lighter and more convenient, and also indirectly increases the service life of the motor. The bearings 4 move in the sliding groove 2, and an anti-friction component 5 is provided between two adjacent bearings 4 at one end of the movable plate 3. The anti-friction component 5 includes a fixed block 51 connected to the movable plate 3. A steel ball 52 is provided on the fixed block 51. The spherical part of the steel ball 52 protrudes from the surface of the fixed block 51, and the steel ball 52 slides in contact with the inner top wall of the slide groove 2. Therefore, when the movable plate 3 moves in the slide groove 2 of the mounting base 1, since the distance between the bearing 4 and the inner top wall of the slide groove 2 is greater than the distance between the steel ball 52 and the inner top wall of the slide groove 2, only the steel ball 52 will slide in contact with the inner top wall of the slide groove 2 first, while the bearing 4 will not contact the inner top wall of the slide groove 2 (i.e., it is in a non-contact state). Therefore, the smoothness of the movable plate 3 when moving left and right can be greatly improved, and the occurrence of jamming, sluggishness and other phenomena can be effectively prevented. Example 2: like Figures 6-8 As shown, bearings 4 and anti-friction components 5 are arranged opposite each other on the movable plate 3. The slide groove 2 in the mounting base 1 of this scheme is slightly higher than the slide groove 2 in the first scheme, so the oppositely arranged bearings 4 and anti-friction components 5 can move easily. The four bearings 4 symmetrically arranged on the movable plate 3 form a support system with uniform force on both sides, which can effectively disperse the weight of the roller shutter door and the impact force during operation, further adapting to large roller shutter doors. When the movable plate 3 slides in the slide groove 2, the steel balls 52 on both sides roll into contact with the inner top wall and inner bottom wall of the slide groove 2 respectively. With the use of double-sided bearings 4, the stability during operation is ensured, reducing the problem of large roller shutter doors getting stuck. Several bearings 4 are made of rust-proof material. After rust prevention treatment and enlargement and thickening forging, several bearings 4 have better load-bearing capacity, smoother use and longer service life when moved.

[0015] The principle and usage process of this utility model: When needed, the mounting base 1 should first be installed on the wall, and then the movable plate 3 should be slid in the slide groove 2 of the mounting base 1. The motor of the roller shutter door should then be installed together with the movable plate 3. Therefore, when the roller shutter door rises or falls, the movable plate 3 will automatically follow, keeping the door in a straight line. During the movement of the movable plate 3, only the steel ball 52 will slide and contact the inner top wall of the slide groove 2 first, while the bearing 4 will not contact the inner top wall of the slide groove 2. This greatly improves the smoothness of the movable plate 3 when it moves left and right, effectively preventing the occurrence of jamming or sticking.

[0016] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
