Description

A hanging wheel assembly structure with good installation stability Technical Field

[0001] This utility model relates to the technical field of sliding door hanging wheel components, and in particular to a hanging wheel component structure with good installation stability. 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 groove of the screw connector under the action of a spring, thus achieving a fixed connection between the mounting base and the screw. However, this structure has the following technical problems:

[0004] Insufficient locking stability: The locking component relies solely on the spring force to maintain its inserted state without any additional locking mechanism. Therefore, during long-term use or when subjected to external vibrations (such as frequent sliding or impacts of the door), the locking component may shift or even detach from the screw's groove, leading to connection failure and posing a safety hazard. Summary of the Invention

[0005] 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 hanging wheel assembly structure with good installation stability.

[0006] A hanging wheel assembly structure with good installation stability is designed for this purpose, including a wheel set, a mounting base, a connecting screw, and a sliding door profile. The connecting screw is threadedly connected to the wheel set. The mounting base is connected to a base plate. A locking space is provided between the mounting base and the base plate. Locking elements are symmetrically arranged on the left and right sides within the locking space. The locking elements are movable relative to the locking space. A first spring is connected between the locking elements and the locking space.

[0007] The mounting base is provided with a mounting hole that communicates with the locking space. The lower end of the connecting screw is provided with a connector. The connector can pass through the mounting hole and be inserted into the locking space. The connector is provided with a limiting ring groove. One end of the locking member can be movably inserted into the limiting ring groove.

[0008] The base plate is provided with a first limiting hole, and the locking member is provided with a second limiting hole; when the locking member is inserted into the limiting ring groove, the first limiting hole and the second limiting hole correspond to each other vertically.

[0009] The sliding door profile is provided with a limiting post, which can be movably inserted into the first limiting hole and the second limiting hole.

[0010] Preferably, the mounting base is provided with guide grooves on the left and right sides respectively, and the locking member is connected to a guide pin, which extends through the guide groove to the outside of the mounting base.

[0011] Preferably, the base plate is provided with a positioning hole, and the connector is movably inserted into the positioning hole.

[0012] Preferably, the connector has a tapered structure that is smaller at the bottom and larger at the top, and the locking member has a guide slope near the end of the connector.

[0013] Preferably, the wheel set includes a hanging wheel seat, the hanging wheel seat is rotatably connected to a plurality of pulleys, a clamping plate is provided on the lower side of the mounting base, an installation space is provided between the clamping plate and the hanging wheel seat, a locking block is movably provided in the installation space, the locking block is provided with a through hole extending from top to bottom, and the connecting screw passes through the through hole from bottom to top and is threadedly connected to the hanging wheel seat;

[0014] The locking block is movable relative to the roller seat between a first position and a second position; when the locking block is in the first position, the locking block abuts against the connecting screw and the roller seat for locking.

[0015] The clamping plate is provided with a locking module for constraining the locking block to remain in a first position.

[0016] Preferably, the connecting hole consists of a rotating channel and a locking channel that are interconnected;

[0017] The connecting screw is provided with a locking plane; when the locking block is in the first position, the wall of the locking channel abuts against the locking plane to constrain the connecting screw to rotate relative to the locking block;

[0018] The locking block is provided with a slot, and the hanging wheel seat is provided with a plug. When the locking block is in the first position, the plug is inserted into the slot.

[0019] Preferably, the clamping plate is provided with a countersunk hole, and the locking module includes a locking pin that is movably inserted into the countersunk hole. The locking pin is provided with a connecting plate, and a second spring is connected to the countersunk hole via the connecting plate.

[0020] The locking block is provided with a locking hole; the second spring is used to apply force to the locking pin so that the locking pin is kept inserted in the locking hole;

[0021] The lower end of the locking pin extends downward through the countersunk hole.

[0022] Preferably, the lower end of the locking pin is connected to an operating handle.

[0023] Compared with the prior art, this utility model has a base plate with a first limiting hole and a locking member with a second limiting hole. When the locking member is inserted into the limiting ring groove, the first limiting hole and the second limiting hole correspond vertically. The sliding door profile has a limiting post, which can be movably inserted into the first limiting hole and the second limiting hole. After the hanging wheel assembly is installed on the sliding door, the movement of the locking member is restricted by the limiting post, thus effectively ensuring that the locking member will not separate from the connector. At the same time, the limiting post plays a role in precise positioning and assembly. When the user connects the mounting base to the sliding door profile, the interlocking of the limiting post can precisely control the relative position of the mounting base and the sliding door profile, avoiding misalignment that could cause errors in the pulley position.

[0038] Referring to Figures 1-6, a hanging wheel assembly structure with good installation stability includes a wheel set 10, a mounting base 210, a connecting screw 30, and a sliding door profile 60. The connecting screw 30 is threadedly connected to the wheel set 10. The mounting base 210 is connected to a base plate 200. A locking space 211 is provided between the mounting base 210 and the base plate 200. Locking elements 220 are symmetrically arranged in the locking space 211, and the locking elements 220 are movable relative to the locking space 211. A first spring 230 is connected between the locking elements 220 and the locking space 211. The mounting base 210 is provided with mounting holes 213 that communicate with the locking space 211. A connector 310 is provided at the lower end of the connecting screw 30. The connector 310 can pass through the mounting hole 213 and be inserted into the locking space 211. The connector 310 is provided with a limiting ring groove 320. One end of the locking member 220 can be movably inserted into the limiting ring groove 320. The base plate 200 is provided with a first limiting hole 201, and the locking member 220 is provided with a second limiting hole 221. When the locking member 220 is inserted into the limiting ring groove 320, the first limiting hole 201 and the second limiting hole 221 correspond to each other vertically. The sliding door profile 60 is provided with a limiting post 600, which can be movably inserted into the first limiting hole 201 and the second limiting hole 221.

[0039] During assembly, the connecting screw 30 drives the connecting head 310 to be inserted from top to bottom into the locking space 211. Under the insertion of the two locking parts 220 on the left and right, the locking parts 220 are inserted into the limiting ring groove 320, thereby constraining the connecting screw 30 to move up and down relative to the mounting base 210. Then, the mounting base 210 and the sliding door profile 60 are plugged into each other and assembled. The limiting post 600 is movably inserted into the first limiting hole 201 and the second limiting hole 221. This plugging constraint not only constrains the positional movement of the locking part 220, but also allows the mounting base 210 and the sliding door profile 60 to be precisely positioned and assembled. Finally, the mounting base 210 and the sliding door profile 60 are connected and fixed with bolts.

[0040] Referring to Figure 2, guide grooves 212 are provided on the left and right sides of the mounting base 210. A guide pin 50 is connected to the locking member 220, extending through the guide grooves 212 to the outside of the mounting base 210. The guide pin 50 has two functions: first, it restricts the movement of the locking member 220; second, when disengaging, the guide pin 50 can be manually moved to move the locking member 220 away from the connector 310. The guide pin 50 can be a nut screw.

[0041] Referring to Figure 2, the base plate 200 is provided with a positioning hole 202, and the connector 310 is movably inserted into the positioning hole 202. The insertion and engagement of the connector 310 with the positioning hole 202 effectively improves the stability of the insertion connection of the connecting screw 30 and also serves as a limit for insertion.

[0042] Referring to Figure 2, the connector 310 has a tapered structure that is smaller at the bottom and larger at the top. The locking member 220 has a guide slope 222 near the end of the connector 310. When the connector 310 is inserted and assembled from bottom to top, the tapered connector 310 contacts the guide slope 222. Under the action of the slope, the connector can squeeze the locking member 220, causing the locking member 220 to move away from the connector 310. Finally, when the limiting ring groove 320 is opposite to the locking member 220, the locking member 220 is pushed into the limiting ring groove 320 by the action of the first spring 230.

[0043] Referring to Figures 2 to 5, the wheel set 10 includes a hanging wheel seat 110, which is rotatably connected to multiple pulleys 120. A clamping plate 100 is provided on the lower side of the mounting base 210, and an installation space 130 is provided between the clamping plate 100 and the hanging wheel seat 110. A locking block 140 is movably disposed within the installation space 130. The locking block 140 is provided with a through hole 150 extending vertically. A connecting screw 30 passes through the through hole 150 from bottom to top and is threadedly connected to the hanging wheel seat 110. The locking block 140 is movably disposed between a first position and a second position relative to the hanging wheel seat 110. When the locking block 140 is in the first position, it abuts against the connecting screw 30 and the hanging wheel seat 110 for locking. The clamping plate 100 is provided with a locking module 40 for constraining the locking block 140 to remain in the first position. During assembly, the connecting screw 30 passes through the through hole 150 and is threadedly connected to the threaded hole above. After the threaded connection is completed, the locking block 140 moves from the second position to the first position, thereby constraining the connecting screw 30 so that it cannot rotate relative to the wheel seat 110.

[0044] Referring to Figure 5, the connecting hole 150 consists of a rotating channel 151 and a locking channel 152 that are interconnected; the connecting screw 30 is provided with a locking plane 300; when the locking block 140 is in the first position, the hole wall of the locking channel 152 abuts against the locking plane 300 to constrain the connecting screw 30 to rotate relative to the locking block 140; the locking block 140 is provided with a slot 160, and the hanging wheel seat 110 is provided with a plug 111; when the locking block 140 is in the first position, the plug 111 is inserted into the slot 160.

[0045] When the locking block 140 is in the first position, the screw 30 is located in the locking channel 152. The locking channel 152 and the wall of the locking channel 152 abut against the locking plane 300 to constrain the connecting screw 30 to rotate relative to the locking block 140.

[0046] When the locking block 140 is in the second position, the screw 30 is located in the rotation channel 151, and the screw 30 can rotate freely relative to the rotation channel 151.

[0047] Referring to Figure 3, the clamping plate 100 is provided with a countersunk hole 101. The locking module 40 includes a locking pin 410 that is movably inserted into the countersunk hole 101. The locking pin 410 is provided with a connecting plate 420, and a second spring 430 is connected to the countersunk hole 101 via the connecting plate 420. The locking block 140 is provided with a locking hole 141. The second spring 430 applies force to the locking pin 410, keeping it inserted in the locking hole 141. The lower end of the locking pin 410 extends downward through the countersunk hole 101. Under the action of the second spring 430, the locking pin 410 is kept inserted in the locking hole 141, thus forming a lock. To unlock, the locking pin 410 needs to be manually pulled downward to disengage it from the locking hole 141, thereby unlocking.

[0048] Referring to Figure 3, an operating handle 440 is connected to the lower end of the locking pin 410. The function of the operating handle 440 is to move the locking pin 410.

[0049] 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.
