A roller shutter roller installation structure

Abstract

The utility model discloses a roller shutter door reel mounting structure, including slide groove and slide plate, and the slide plate is installed in the slide groove through the gyro wheel, and the gyro wheel's pivot end installs the steel ball, and the steel ball cooperates with the lateral wall of slide plate and makes gyro wheel side surface not contact slide plate. The steel ball of gyro wheel pivot end installation can press against the lateral wall of slide groove, avoids gyro wheel side surface contact slide groove to protect gyro wheel. Replaces the sliding friction of original structure with the rolling friction, reduces the resistance of slide plate in the motion in the slide groove, and further protects the door piece not to be extruded in the winding process.

Description

Technical Field

[0001] This utility model relates to the field of roller shutter doors, specifically to a movable mounting structure for a roller. Background Technology

[0002] Chinese patent CN206111048U discloses an automatic dust-removing roller shutter door. The main feature of this technical solution is that its motor mounting bracket drives the motor to move back and forth within a movable support. The use of a movable motor support effectively avoids friction between the roller shutter door panel and the guide rail. However, the motor support consists of four rollers mounted on the side of a square mounting plate. In actual use, this can lead to wear and even damage to the rollers due to contact between the rollers' sides and the side of the movable support. Summary of the Invention

[0003] The purpose of this invention is to address the problem of wear on the side of the rollers of the moving bracket of a roller shutter door by installing ball bearings on the side of the rollers, using the ball bearings to press against the side of the bracket, and having the side of the rollers on the wall contact the side plate.

[0004] The technical solution of this utility model: A roller shutter door roller mounting structure includes a slide groove and a slide plate. The slide plate is mounted in the slide groove by a roller. A steel ball is installed at the end of the roller's shaft. The steel ball cooperates with the side wall of the slide plate so that the side of the roller does not contact the slide plate.

[0005] Steel balls are installed at both ends of the shaft.

[0006] The skateboard has wheels installed on both sides.

[0007] The sliding plate is fixed to the walls on both sides of the roller shutter, and the two ends of the roller shutter shaft are fixed to the sliding plate.

[0008] The end of the shaft has a groove for mounting a steel ball, and a retaining ring is used to hold the steel ball in the groove.

[0009] The retaining ring is a ring-shaped structure, with the inner surface of the ring machined to form an arc surface that mates with the groove and the steel ball. The beneficial effects of this utility model are: 1. The steel ball installed at the end of the roller shaft can press against the side wall of the chute, preventing the side of the roller from contacting the chute, thus protecting the roller.

[0010] 2. Replacing the sliding friction of the original structure with rolling friction reduces the resistance of the slide plate moving in the groove, further protecting the door panel from being squeezed during the winding process. Attached Figure Description

[0015] Figure 5 This is a structural schematic diagram of Example 4. Detailed Implementation

[0016] Example 1: like Figure 1 and Figure 2 The roller shutter has a rectangular sliding plate installed at each end of its roller shaft. Holes are drilled at the four corners of each sliding plate to install rotating shafts, each with a roller. The sliding plate is installed in a groove fixed to the wall. The upper and lower ends of the groove's side plates are bent inwards, creating a 90-degree bend in cross-section. A groove for a steel ball is located at the far center of the rotating shaft. The groove's depth is three-quarters the diameter of the steel ball, allowing a portion of the ball to protrude. The steel ball supports the side wall of the groove, preventing wear on the rollers. During installation, the sliding plate is inserted into the groove while the steel ball is placed inside, using the groove to restrain the ball within the groove at the end of the rotating shaft.

[0017] Example 2: This embodiment adds a retaining ring to the end of the rotating shaft based on the previous embodiment, with the structure as follows: Figure 3 First, the steel ball is placed into the groove at the end of the shaft. Then, the retaining ring is glued or welded into the groove. The inner diameter of the retaining ring is smaller than the diameter of the steel ball, which can constrain the steel ball in the groove. Furthermore, both the outer and inner circles of the retaining ring are machined with arc surfaces that can mate with the steel ball and the groove.

[0018] Example 3: like Figure 4 In this embodiment, the slide plate is rectangular. Holes are drilled at the four corners of the outer side of each slide plate to install a pivot, and rollers are mounted on the pivot. Both ends of the pivot are provided with grooves into which steel balls can be embedded. After the slide plate is inserted into the groove, the steel balls at both ends of the pivot can prevent the rollers from contacting the slide plate with the groove, thus avoiding sliding friction.

[0019] Example 4: like Figure 5 In this embodiment, the slide plate is rectangular. Holes are drilled at the four corners of the outer side of each slide plate to install a pivot. Rollers are installed at both ends of the pivot. At the same time, grooves are opened at both ends of the pivot to embed steel balls. After the slide plate is inserted into the groove, the steel balls at both ends of the pivot can prevent the rollers on both sides from contacting the groove, thus avoiding wear caused by sliding friction.
