Abstract
Description
An easy-to-assemble roller assembly Technical Field
[0001] This utility model relates to the field of sliding door roller technology, and in particular to a roller assembly that is easy to assemble. Background Technology
[0002] Sliding doors (such as sliding doors and hanging doors) are widely used in homes, offices, and commercial spaces. One of their core components is the hanging wheel assembly, which supports the door and allows it to slide smoothly along the track. Existing hanging wheel assemblies typically include a mounting base, a set of hanging wheels, and a screw structure connecting the two. The upper end of the screw connects to the mounting base, and the lower end is fixed to the hanging wheel assembly to enable the suspension and movement of the door.
[0003] In existing technologies, a plug-in locking mechanism is typically used to facilitate quick connection between the screw and the mounting base. Specifically, the mounting base has pluggable locking mechanisms on both sides, which automatically insert into the annular grooves of the screw connector under spring pressure, thus achieving a fixed connection between the mounting base and the screw. The problem with this structure is that separation requires simultaneously moving the locking mechanisms on both sides before pulling out the screw. However, this unlocking and disassembly method is not convenient for single-person operation; after unlocking the locking mechanisms on both sides, a single person cannot free their hands to operate the screw, and further improvements are needed. Summary of the Invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a conveniently assembled hanging wheel assembly.
[0005] A conveniently assembled hanging wheel assembly designed for this purpose includes a wheel seat, a mounting base, and a screw. The screw is threadedly connected to the wheel seat. The mounting base has a locking space, and the upper surface of the mounting base has an elliptical locking hole that communicates with the locking space.
[0006] The screw is connected to an elliptical locking plate, which can be inserted into the locking space through the elliptical locking hole;
[0007] The upper surface of the locking space is provided with a positioning hole, and the elliptical locking plate is provided with a positioning post; when the minor axis of the elliptical locking plate coincides with the major axis of the elliptical locking hole, the positioning post can be inserted into the positioning hole from bottom to top.
[0008] The locking space is provided with an elastic module, which is used to apply an upward force to the elliptical locking plate.
[0009] Preferably, the bottom surface of the mounting base is provided with a mounting hole that communicates with the locking space, and the lower end of the screw is provided with an extension post, which is movably inserted into the mounting hole.
[0010] Preferably, the elastic module includes a movable plate that is vertically movable within the locking space, guide posts are provided on the left and right sides of the movable plate, and countersunk holes are provided on the left and right sides of the mounting base, the countersunk holes communicating with the locking space and penetrating downward through the mounting base;
[0011] The guide post is movably inserted into the recessed hole, a limit bolt is provided in the recessed hole, and a spring is provided between the movable plate and the bottom wall of the locking space.
[0012] Preferably, the mounting base is provided with a base plate at its bottom, and the locking space is disposed between the mounting base and the base plate.
[0013] Preferably, the wheel seat is provided with multiple pulleys for rotatable rotation.
[0014] Compared with the prior art, this invention, constrained by the elliptical locking hole and the elliptical locking plate, keeps the elliptical locking plate within the locking space. Furthermore, the cooperation of the positioning hole and the positioning pin prevents the screw from rotating relative to the mounting base. Simultaneously, the elastic component constrains the elliptical locking plate upwards, keeping the positioning pin inserted into the positioning hole. To unlock, the screw must first be moved downwards to dislodge the positioning pin from the positioning hole. Then, the screw is rotated until the major axis of the elliptical locking plate coincides with the major axis of the elliptical locking hole, allowing the screw to be pulled upwards and the elliptical locking plate to disengage from the locking space. This invention is simple to operate and easy to disassemble. Attached Figure Description

[0030] Referring to Figures 1-7, a conveniently assembled hanging wheel assembly includes a wheel seat 10, a mounting base 20, and a screw 30. The screw 30 is threadedly connected to the wheel seat 10. The mounting base 20 has a locking space 210, and its upper surface has an elliptical locking hole 220 communicating with the locking space 210. The screw 30 is connected to an elliptical locking plate 320, which can pass through the elliptical locking hole 220 and be inserted into the lock. Within the locking space 210; the upper surface of the locking space 210 is provided with a positioning hole 200, and the elliptical locking plate 320 is provided with a positioning post 330; when the minor axis of the elliptical locking plate 320 coincides with the major axis of the elliptical locking hole 220, the positioning post 330 can be inserted into the positioning hole 200 from bottom to top; the locking space 210 is provided with an elastic module 400, which is used to apply an upward force to the elliptical locking plate 320.
[0031] In this invention, the major axis of the elliptical locking hole is greater than or equal to the major axis of the elliptical locking plate; the minor axis of the elliptical locking hole is greater than or equal to the minor axis of the elliptical locking plate.
[0032] This invention, constrained by an elliptical locking hole and an elliptical locking plate, keeps the elliptical locking plate within the locking space. Furthermore, the cooperation of the positioning hole and the positioning pin prevents the screw from rotating relative to the mounting base. Simultaneously, the included elastic component constrains the elliptical locking plate upwards, keeping the positioning pin inserted into the positioning hole. To unlock, the screw must first be moved downwards to dislodge the positioning pin from the positioning hole. Then, the screw is rotated until the major axis of the elliptical locking plate coincides with the major axis of the elliptical locking hole, allowing the screw to be pulled upwards and the elliptical locking plate to disengage from the locking space. This invention is simple to operate and easy to disassemble.
[0033] Referring to Figures 4 and 5, the bottom surface of the mounting base 20 is provided with a mounting hole 230 that communicates with the locking space 210. An extension post 310 is provided at the lower end of the screw 30, and the extension post 310 is movably inserted into the mounting hole 230. The insertion of the extension post 310 into the mounting hole 230 effectively improves the connection stability of the screw 30.
[0034] Referring to Figure 4, the elastic module 400 includes a movable plate 40 that is vertically movable within the locking space 210. Guide posts 410 are provided on the left and right sides of the movable plate 40. The mounting base 20 is provided with countersunk holes 240 on the left and right sides, respectively. The countersunk holes 240 communicate with the locking space 210 and penetrate downward through the mounting base 20. The guide posts 410 are movably inserted into the countersunk holes 240. Limit bolts 50 are provided in the countersunk holes 240. A spring 60 is provided between the movable plate 40 and the bottom wall of the locking space 210.
[0035] During assembly, the screw 30, carrying the elliptical locking plate 320, is inserted into the locking space 210. During this process, the elliptical locking plate 320 presses the moving plate 40 downwards, compressing and storing force in the spring 60. Then, by rotating the elliptical locking plate 320 by 90 degrees, the minor axis of the elliptical locking plate coincides with the major axis of the elliptical locking hole. Then, by moving the elliptical locking plate 320 upwards, the positioning pin 330 is inserted from bottom to top into the positioning hole 200. During this process, the spring 60 releases its stored force, causing the moving plate 40 to move upwards and conform to the elliptical locking plate, preventing it from moving downwards.
[0036] Referring to Figure 7, the guide post 410 of this invention is movably inserted into the recessed hole 240. During unlocking, the elliptical locking plate 320 needs to move downwards to separate the positioning post 330 from the positioning hole 220. However, when the mounting base 20 is installed on the sliding door profile 70, the positioning post 330 cannot move downwards due to the limitation of the sliding door profile 70. That is, the elliptical locking plate 320 cannot move downwards relative to the locking space 210, thus preventing unlocking. Disassembly is required; the mounting base must first be separated from the sliding door profile 70 before the guide post 410 has room to move downwards.
[0037] Furthermore, the spring 60 is sleeved on the guide post 410.
[0038] Referring to Figure 3, the bottom of the mounting base 20 is provided with a base plate 250, and the locking space 210 is disposed between the mounting base 20 and the base plate 250.
[0039] In this invention, the wheel seat 10 is rotatably equipped with multiple pulleys.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
