Description

Technical Field

[0001] This utility model relates to the technical field of sliding door pulley devices, specifically to a side-mounted movable hook for a sliding door. Background Technology

[0002] Sliding doors are typically mounted on guide rails in the door frame using a pulley system, allowing them to move smoothly along the rails.

[0003] Refer to application numbers CN202421279761.0 and CN202421279703.8 Existing pulley systems typically feature a connecting seat for attaching to the door panel. This connecting seat and the pulley unit are rigidly connected, meaning the connecting seat cannot swing relative to the pulley system. When the door panel is mounted on the pulley system and hooked into the guide rail via the connecting seat, the rigid connection prevents flexible adjustment of the door panel's height based on the guide rail's flatness and the door panel's weight distribution. Therefore, when the user moves the door panel left or right, the rigid connection prevents the pulleys from adaptively adjusting their force, leading to uneven force distribution. In severe cases, some pulleys may even be suspended in mid-air. This not only accelerates wear and shortens the pulleys' lifespan but also causes jamming and rattling during sliding, reducing the smoothness and stability of the sliding door and resulting in a poor user experience. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a sliding door side-mounted movable hook.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A sliding door side-mounted movable hook includes a pulley device and a connecting seat. The pulley device includes a pulley seat and a sliding wheel mounted on the pulley seat. The pulley seat is characterized by having an mounting arm on the pulley seat and a connecting arm on the connecting seat. The mounting arm and the connecting arm are rotatably connected together by a connecting shaft. The connecting seat is rotatably swinging relative to the pulley seat with the connecting shaft as the rotation center.

[0007] In this utility model, the mounting arm is provided with a mounting shaft hole extending from front to back, the connecting shaft is fixedly connected to the connecting arm, and the connecting shaft is rotatably adapted to the mounting shaft hole.

[0008] In this utility model, a swing clearance opening extending from front to back is provided on the lower side of the mounting shaft hole. The upper end of the swing clearance opening is connected through the mounting shaft hole, and the lower end is connected through the bottom of the mounting arm. The upper end of the connecting arm is inserted into the swing clearance opening.

[0009] In this invention, the width A of the swing clearance opening is greater than the width B of the connecting arm, and the width A of the swing clearance opening is less than the diameter of the mounting shaft hole and the diameter of the connecting shaft.

[0010] In this invention, both the front and rear ends of the mounting shaft hole and the swing clearance opening are provided through the mounting arm.

[0011] In this utility model, the mounting arm is provided with front and rear limiting grooves on the left and / or right sides, and the connecting seat is threaded with limiting bolts that are inserted into the front and rear limiting grooves to prevent the connecting shaft from moving back and forth and coming out of the mounting shaft hole. At least one limiting bolt is inserted into each front and rear limiting groove.

[0012] In this utility model, the connecting seat is provided with a connecting protrusion, the connecting protrusion is provided with a protrusion screw hole, and the screw section of the limiting bolt has at least a partial thread engagement in the protrusion screw hole.

[0013] In this utility model, the top of the connecting seat is provided with a bolt relief groove, the lower end of the connecting protrusion is located in the bolt relief groove and connected to the connecting seat, and the limiting bolt is located at least partially in the bolt relief groove.

[0014] In this invention, the connecting shaft, connecting arm, and connecting seat are integrally formed and connected from top to bottom.

[0015] In this utility model, the pulley seat is provided with a mounting slot, the upper end of the mounting arm is fixed in the mounting slot, and the pulley seat and the mounting arm are fixed together by mounting bolts.

[0016] The beneficial effects of this utility model are as follows: First, an mounting arm is provided on the pulley seat, then a connecting arm is provided on the connecting seat. The mounting arm and the connecting arm are then rotatably connected together via a connecting shaft. This allows the connecting seat to rotate and swing relative to the pulley seat around the connecting shaft. This allows the height of the door leaf to be flexibly adjusted during left or right movement of the door leaf through the swinging action of the connecting seat. This ensures that each sliding wheel of the pulley device maintains good contact with the guide rail surface, avoiding uneven force distribution caused by rigid connections and preventing some sliding wheels from becoming suspended during door leaf movement. This reduces abnormal wear of the sliding wheels and extends the service life of the pulley device. Simultaneously, it eliminates the risk of door leaf jamming or derailment caused by uneven force distribution or suspension of the sliding wheels, ensuring the smoothness and stability of the door leaf sliding process.

[0027] Reference Figure 1-5 A sliding door side-mounted movable hook includes a pulley device 1 and a connecting seat 2. The pulley device 1 includes a pulley seat 11 and sliding wheels 13 mounted on the pulley seat 11. Two sliding wheels 13 are arranged from left to right on the front side of the sliding wheels 13, and the other two sliding wheels 13 are arranged from left to right on the rear side of the sliding wheels 13. Each sliding wheel 13 is mounted on the pulley seat 11 through a wheel axle 12. The wheel axle 12 is a pulley bolt that passes through the center hole of the sliding wheel 13 and is threaded onto the pulley seat 11. The structure of the sliding wheel 13 being mounted on the pulley seat 11 through the wheel axle 12 is a conventional existing technology and will not be described in detail.

[0028] Furthermore, the pulley seat 11 is provided with a mounting arm 3, and the connecting seat 2 is provided with a connecting arm 4. The mounting arm 3 and the connecting arm 4 are rotatably connected together by a connecting shaft 5. The connecting seat 2 can be rotated and swung relative to the pulley seat 11 with the connecting shaft 5 as the rotation center. Specifically, the connecting seat 2 can be rotated and swung left and right relative to the pulley seat 11 with the connecting shaft 5 as the rotation center.

[0029] In this embodiment, a mounting arm 3 is first provided on the pulley seat 11, and then a connecting arm 4 is provided on the connecting seat 2. The mounting arm 3 and the connecting arm 4 are then rotatably connected together via a connecting shaft 5, allowing the connecting seat 2 to rotate and swing relative to the pulley seat 11 around the connecting shaft 5. This allows the height of the door leaf to be flexibly adjusted by the swinging action of the connecting seat 2 during left or right movement, ensuring that each sliding wheel 13 of the pulley device 1 maintains good contact with the guide rail surface. This not only avoids uneven force caused by rigid connection but also prevents some sliding wheels 13 from being suspended during door movement, reducing abnormal wear of the sliding wheels 13 and extending the service life of the pulley device 1. At the same time, it eliminates the risk of door leaf jamming or derailment caused by uneven force or suspension of the sliding wheels 13, ensuring the smoothness and stability of the door leaf sliding process.

[0030] In this embodiment, the mounting arm 3 is provided with a mounting shaft hole 31 extending from front to back. The connecting shaft 5 is fixedly connected to the connecting arm 4, and the connecting shaft 5 is rotatably adapted in the mounting shaft hole 31, thereby realizing a rotatable connection between the mounting arm 3 and the connecting arm 4.

[0031] In this embodiment, a swing clearance opening 32 extending from front to back is provided on the lower side of the mounting shaft hole 31. The upper end of the swing clearance opening 32 is in through communication with the mounting shaft hole 31, and the lower end is through the bottom of the mounting arm 3. The upper end of the connecting arm 4 is inserted into the swing clearance opening 32. The width A of the swing clearance opening 32 is greater than the width B of the connecting arm 4, so that a swing clearance gap is left between the swing clearance opening 32 and the connecting arm 4, allowing the connecting arm 4 to swing left and right within the swing clearance opening 32. The width A of the swing clearance opening 32 is less than the diameter of the mounting shaft hole 31 and the diameter of the connecting shaft 5, so that the connecting shaft 5 cannot move downward and disengage from the mounting shaft hole 31 through the swing clearance opening 32.

[0032] In this embodiment, the mounting shaft hole 31 and the swing clearance opening 32 are both provided through the mounting arm 3 at both ends, so as to facilitate the insertion of the connecting shaft 5 and the connecting arm 4 from the front end or the rear end of the pulley seat 11 into the corresponding mounting shaft hole 31 and swing clearance opening 32, thereby improving the ease of installation and also facilitating subsequent disassembly and maintenance.

[0033] In this embodiment, the left side of the mounting arm 3 is provided with a front and rear limiting groove 33. The connecting seat 2 is threaded with a limiting bolt 6 that is inserted into the front and rear limiting groove 33 to prevent the connecting shaft 5 from moving forward or backward and dislodging from the mounting shaft hole 31. At least one limiting bolt 6 is inserted into each front and rear limiting groove 33. Under the constraint of the limiting bolt 6, the forward and backward movement of the connecting shaft 5 is restricted, thereby ensuring that the connecting shaft 5 is stably fitted in the mounting shaft hole 31. In other embodiments, the front and rear limiting groove 33 may also be provided on the right side of the mounting arm 3, or both sides of the mounting arm 3 may be provided with front and rear limiting grooves 33, so that the corresponding limiting bolts 6 are inserted into the front and rear limiting grooves 33 to achieve front and rear constraint and limitation between the connecting arm 4 and the mounting arm 3, thereby preventing the connecting shaft 5 from moving forward or backward and dislodging from the mounting shaft hole 31.

[0034] In this embodiment, the connecting seat 2 is provided with a connecting protrusion 21, and the connecting protrusion 21 is provided with a protrusion screw hole 22. The screw section of the limiting bolt 6 is at least partially threaded in the protrusion screw hole 22. By rotating the limiting bolt 6, the position of the screw section of the limiting bolt 6 and the protrusion screw hole 22 can be adjusted, so that the screw section of the limiting bolt 6 can be inserted into or withdrawn from the front and rear limiting grooves 33.

[0035] In this embodiment, the top of the connecting seat 2 is provided with a bolt relief groove 23, the lower end of the connecting protrusion 21 is located in the bolt relief groove 23 and is integrally formed and connected to the connecting seat 2, and at least part of the limiting bolt 6 is located in the bolt relief groove 23, thereby reducing the volume of the limiting bolt 6 protruding outward and achieving the purpose of reducing the overall product volume.

[0036] In this embodiment, the connecting seat 2 is provided with a connecting mating hole 24, which is used to insert and fit bolts to fix the door leaf.

[0037] In this embodiment, the connecting shaft 5, connecting arm 4, and connecting seat 2 are integrally formed and connected from top to bottom, resulting in a highly stable structure.

[0038] In this embodiment, the pulley seat 11 is provided with a mounting slot 111, and the upper end of the mounting arm 3 is fixed in the mounting slot 111. The pulley seat 11 and the mounting arm 3 are fixed together by a mounting bolt. The screw of the mounting bolt passes through the connecting hole 112 on the pulley seat 11 and is threaded into the mounting screw hole 34 of the mounting arm 3. The mounting bolt is not shown in the drawings.

[0039] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
