Description

Technical Field

[0001] This utility model relates to the field of hanging wheel buffer technology, and in particular to a bidirectional self-leveling detachable buffer hanging wheel mechanism. Background Technology

[0002] The hanging wheel mechanism, also known as the upper suspension pulley assembly or hanging wheel system, refers to a set of mechanical devices installed on the top of the sliding door to suspend the door leaf in the upper track and achieve horizontal sliding. The hanging wheel mechanism is the core component of the sliding door system, which directly determines the stability, smoothness, quietness and safety of the door leaf operation.

[0003] According to application number 202422337663.4, a detachable roller buffer is disclosed, belonging to the technical field of roller buffers. It includes a movable rod, a buffer movable component, a front roller connector, a front roller component, a rear roller connector, and a rear roller component. This utility model uses a first bolt to connect the front roller connector and a second bolt to connect the rear roller connector. When the buffer cylinder of the buffer movable component located inside the movable rod leaks oil or the first spring is damaged, the buffer movable component can be replaced by removing either the front or rear roller connector, thus facilitating maintenance during use. Furthermore, by hinged to the front roller component at the end of the front roller connector away from the movable rod, and with a second spring provided on the side of the front roller connector facing the front roller component, the second spring, in conjunction with the hinged structure, enables the roller buffer's pulley components to automatically level themselves.

[0004] This comparative case effectively solves the problem that the pulley components of existing roller buffers do not have an automatic leveling function. However, in the comparative case, the buffer movable component is buffered by the cooperation of a buffer cylinder and a spring. To ensure stable buffering effect, both require regular maintenance. When a component is damaged and needs to be disassembled for maintenance, the rear roller component needs to be removed to provide an opening for the buffer movable component to be removed. However, the buffer movable component is only slidably connected to the inner cavity of the movable rod, which not only has poor stability, but is also difficult to remove from the movable rod quickly due to the limitations of the surrounding frame and other structures, thus reducing the efficiency of its maintenance.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a bidirectional self-leveling detachable buffer roller mechanism. The bidirectional self-leveling detachable buffer roller mechanism includes a roller assembly 1 and a buffer assembly 2. The movable rod 11 and the front roller assembly 12 are hinged together, and a leveling spring is provided in the front roller assembly 12. When the front roller assembly 12 is subjected to pressure from the door body, the leveling spring is compressed. In conjunction with the rear roller assembly 13, the roller assembly can realize the bidirectional automatic leveling function of the pulley component. Through the setting of the buffer assembly 2, the inertial impact force when the door is closed or opened to the position can be absorbed to prevent violent impact. At the same time, the components of the buffer assembly 2 can be easily disassembled to reduce the difficulty of maintenance.

[0034] Specifically, the hanging wheel assembly 1 includes a movable rod 11, with a front hanging wheel 12 hinged to one side of the movable rod 11 and a rear hanging wheel 13 provided on the other side of the movable rod 11.

[0035] The roller assembly 1 and the buffer assembly 2 together constitute the main body of the roller buffer. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here. The rear roller component 13 is connected to the buffer assembly 2. While providing a certain support force, it can also be directly removed from the inside of the movable rod 11 when it is removed, thereby improving the convenience of maintenance.

[0036] Specifically, the buffer assembly 2 is disposed in the inner cavity of the movable rod 11, including a plate 21 located in the inner cavity of the movable rod 11. Movable blocks 22 are provided at both ends of the plate 21. A buffer structure 23 is provided between the two movable blocks 22 and the plate 21. A connecting structure 24 is provided in the inner cavity of the plate 21.

[0037] Example 2, refer to Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the rear hanging wheel component 13 includes a wheel frame 131 disposed at one end of the movable rod 11. Both sides of the wheel frame 131 are provided with rear hanging wheel bodies 132. One end of the wheel frame 131 extends into the inner cavity of the movable rod 11 and is fixedly connected to the inner cavity by bolts. Both sides of one end of the wheel frame 131 are fixedly connected with connecting plates 133. One end of the connecting plate 133 has an opening, and one end of the connecting plate 133 is fixedly connected with a retaining ring 134.

[0039] By setting the wheel frame 131, one end of the movable rod 11 can be blocked while supporting the rear hanging wheel body 132. The opening on one side of the connecting plate 133 is used to provide movement space for the slider 221 on the surface of the front movable block 22. Under the action of the connecting plate 133, it can cooperate with the connecting structure 24 to connect the rear hanging wheel 13 and the buffer assembly 2 into one unit. Thus, when the rear hanging wheel 13 is removed, the buffer assembly 2 can be directly taken out from the inside of the movable rod 11, thereby saving maintenance time.

[0040] Specifically, sliders 221 are fixedly connected to both ends of the movable block 22, and grooves for limiting the sliders 221 are provided on both sides of the inner cavity of the movable rod 11. Slots 222 are provided on both ends of the surface of the movable block 22.

[0041] The slider 221, together with the groove inside the movable rod 11, can limit the movement of the movable block 22. The slot 222 serves as the connection point between the movable block 22 and the buffer structure 23, providing a basis for the assembly and disassembly of the two.

[0042] Specifically, the buffer structure 23 includes four blocks 231, which are stacked in pairs and respectively located at both ends of the plate 21. Each of the two stacked blocks 231 has a card holder 232 fixedly connected to the side away from each other, and the card holder 232 engages with the inner cavity of the card slot 222.

[0043] Specifically, a fixing block 233 is provided on the side of the block 231 near the plate 21, and an installation block is fixedly connected to the side of the fixing block 233 near the plate 21. Two installation slots are provided on the top and bottom of the plate 21, and the installation block is fixedly connected to the inner cavity of the installation slot by bolts.

[0044] Specifically, connecting grooves 2311 are provided on both sides above the two lower blocks 231, and connecting blocks 2312 are fixedly connected to both sides below the two upper blocks 231. The connecting blocks 2312 extend into the inner cavity of the connecting grooves 2311 and are fixedly connected to the inner cavity of the grooves by bolts.

[0045] Specifically, a limiting member 234 is provided between the block 231 and the fixed block 233. The limiting member 234 includes a limiting frame and a limiting plate. One side of the limiting frame is fixedly connected to the block 231, and one side of the limiting plate is fixedly connected to the fixed block 233. One side of the limiting plate extends into the inner cavity of the limiting frame and is slidably connected to its inner cavity.

[0046] Specifically, a telescopic rod 235 is fixedly connected to the side of the lower fixing block 233 away from the plate 21, and the end of the telescopic rod 235 away from the fixing block 233 is fixedly connected to the lower block 231. A damper 236 is fixedly connected to the side of the upper fixing block 233 away from the plate 21, and the end of the damper 236 away from the fixing block 233 is fixedly connected to the upper block 231.

[0047] Both block 231 and fixing block 233 serve to support and fix the surface components. The connecting groove 2311 and connecting block 2312 cooperate to connect the two stacked blocks 231, improving the stability of the connection. The bracket 232 is used to engage with the inner cavity of the slot 222, connecting the movable block 22 and the buffer structure 23. The mounting block on the surface of the buffer structure 23 cooperates with the mounting groove on the surface of the plate 21, connecting the buffer structure 23 and the plate 21. Thus, the plate 21, movable block 22 and buffer structure 23 can be separated into independent parts to facilitate maintenance.

[0048] The limiting frame of the limiting component 234 cooperates with the limiting plate to position the block 231 and the fixed block 233, ensuring that the two are at the same level, and at the same time can provide a certain degree of protection for the telescopic rod 235 and the damper 236.

[0049] The telescopic rod 235 and the damper 236 work together to buffer the impact force when the door is closed or opened, reduce noise and damage to the door, thereby improving the service life of the door to a certain extent.

[0050] Specifically, the connecting structure 24 includes receiving grooves 241 opened on both sides of the plate 21. A locking block 242 is slidably connected to the inner cavity of the receiving groove 241. One end of the locking block 242 extends into the inner cavity of the retaining ring 134 and engages with its inner cavity. A return spring 243 is fixedly connected to the side of the two locking blocks 242 that are close to each other. The end of the return spring 243 away from the locking block 242 is fixedly connected to the inner wall of the receiving groove 241.

[0051] Specifically, the telescopic rod 235 is an automatic retraction rod with a built-in compression spring and a reset spring 243, both of which are stainless steel springs. The slider 221 located on the surface of the front movable block 22 is movably connected to the opening at one end of the connecting plate 133, and the thickness of the connecting plate 133 is half the length of the slider 221.

[0052] The receiving groove 241 is used to receive the locking block 242 and the return spring 243 and provide movable space for both. The return spring 243 is used to provide a return force for the locking block 242. After the locking block 242 is inserted into the inner cavity of the retaining ring 134, it can engage with it, thereby connecting the rear hanging wheel 13 and the buffer assembly 2, so that the two can be disassembled synchronously.

[0053] The telescopic rod 235 has a built-in compression spring that can automatically reset when the pressure is removed. The reset spring 243 is a stainless steel spring with a long service life.

[0054] When in use, when the door is closed forcefully, the telescopic rod 235 undergoes elastic deformation and cooperates with the damper 236 to absorb kinetic energy, prevent violent impact, and reduce abnormal noise. When maintenance is required on a certain component of the buffer assembly 2, first remove the bolt between the movable rod 11 and the rear hanging wheel 13. After removal, pull the rear hanging wheel 13 forward to remove it from the movable rod 11. Under the locking action of the retaining ring 134 and the connecting structure 24, the buffer assembly 2 can move with the rear hanging wheel 13, thereby removing the buffer assembly 2 from the inside of the movable rod 11.

[0055] After the buffer assembly 2 is removed, press the locking block 242 to move it out of the inside of the locking ring 134. After it is moved out, the locking effect between the rear roller 13 and the buffer assembly 2 disappears, and the buffer assembly 2 can be removed from between the two connecting plates 133, thereby separating the rear roller 13 and the buffer assembly 2. Then, remove the bolts between the plate 21 and the fixing block 233 to separate them. After separation, remove the bolts on the surface of the lower block 231 to separate the two stacked blocks 231. After separation, the locking effect between the slot 222 and the bracket 232 can be released, thereby separating the plate 21, the movable block 22, the block 231 and the fixing block 233 as a whole. Finally, the damaged parts can be maintained.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
