Description

Technical Field

[0001] This utility model relates to the field of roller structure technology, and more specifically, to a roller structure with a heavy-duty bidirectional limiting mechanism. Background Technology

[0002] In industrial production, logistics warehousing and heavy equipment handling, roller structures are the core components for realizing horizontal movement of equipment. Their load-bearing performance and operational stability directly determine production efficiency and operational safety. Currently, conventional roller structures on the market generally have design flaws that are not suitable for heavy-load conditions. On the one hand, most structures use a single load-bearing unit and lack targeted reinforcement design. When bearing heavy equipment, they are prone to roller deformation and position displacement due to stress concentration, which cannot meet the requirements of long-term heavy-load use. The existing publication CN219910437U discloses a bidirectional positioning guide pulley structure. A roller bracket, which moves up and down on the upper clamp, is mounted on the upper clamp. A horizontally placed second roller and a vertically placed first roller are rotatably connected to the roller bracket. The roller bracket and the upper clamp are clamped and fixed by a clamping assembly. In use, the roller bracket is inserted into the guide rail groove of the guide rail. The width of the second roller is equal to the width of the guide rail groove, preventing the upper clamp connected to the roller bracket from wobbling left and right within the guide rail, thus achieving horizontal positioning of the sliding door. Then, by releasing the clamping assembly, the relative height between the roller bracket and the upper clamp is adjusted, causing the roller bracket to move up and down on the upper clamp, pressing the first roller against the inner top wall of the guide rail groove, forming vertical support with the roller below the sliding door. This ensures smooth sliding of the sliding door and reduces the risk of derailment. The inventors discovered the following problems with the existing technology during the development of this utility model: Traditional bases with roller structures are often supported by a single roller on one side, which is prone to bending and deformation under heavy load conditions, resulting in insufficient load-bearing capacity. In addition, the single rotating mechanism can concentrate heavy load pressure, causing the roller to tilt to one side, resulting in poor stability during movement and making it difficult to meet the long-term use requirements of heavy-duty equipment. Therefore, a roller structure with a heavy-duty bidirectional limiting mechanism is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a roller structure with a heavy-duty bidirectional limiting mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a roller structure with a heavy-duty bidirectional limiting mechanism, comprising a base plate, a limiting mechanism, a rotating mechanism, and a slide rail assembly. The limiting mechanism is installed below the base plate, and the rotating mechanism is installed on the side of the limiting mechanism. The slide rail assembly is provided below the rotating mechanism. The limiting mechanism includes a connecting component, a fixing component, and a sliding component. The fixing component is installed on the side of the connecting component, and the sliding component is installed on the side of the fixing component away from the connecting component.

[0005] Preferably, the connecting assembly includes a connecting plate, a top plate, and a protective plate, with the top plate installed below the connecting plate and the protective plate installed on the side of the top plate.

[0006] By adopting the above technical solution, a stable connection with the base plate is achieved using a connecting plate, the top plate enhances the vertical load-bearing strength, and the protective plate can shield the internal parts of the limiting mechanism and the rotating mechanism, preventing impurities from entering or parts from being bumped under heavy load conditions, thus improving the durability of the structure.

[0007] Preferably, the fixing assembly includes a fixing post, a side plate, and a partition plate, wherein the side plate is mounted on the outer diameter surface of the fixing post, and the partition plate is mounted on the side of the side plate.

[0008] By adopting the above technical solution, the fixed column positions the side plate, the side plate fixes the rotating mechanism and the limiting mechanism, and the isolation plate separates the two sets of rotating mechanisms to prevent mutual interference during movement and ensure that the limiting and sliding functions are independent and reliable.

[0009] Preferably, the sliding assembly includes a sliding plate, a connecting block, and a fixing bolt, wherein the connecting block is mounted on the side of the sliding plate, and the fixing bolt is mounted on the side of the connecting block away from the sliding plate.

[0010] By adopting the above technical solution, the side of the slide plate and the slide rail assembly fits together to achieve smooth sliding. The connecting block serves as a transition structure to adapt to the installation angle. The fixing bolts fix the sliding assembly and the fixed assembly to prevent loosening between the sliding assembly and the fixed assembly when moving under heavy load.

[0011] Preferably, the rotating mechanism includes a roller, a first limiting plate, and a roller, wherein the first limiting plate is mounted on the outer diameter surface of the roller, and the roller is provided on the side of the first limiting plate.

[0012] By adopting the above technical solution, the roller and bearing are used to realize the rotation of the roller, reducing the frictional resistance under heavy load. The two sets of first limit plates limit the two sides of the roller respectively, preventing relative sliding between the roller and the limit mechanism during horizontal movement.

[0013] Preferably, the slide rail assembly includes a slide rail plate, a second limiting plate, and anti-slip posts, with the second limiting plate installed above the slide rail plate and the anti-slip posts installed below the slide rail plate.

[0014] By adopting the above technical solution, the slide rail plate provides a sliding track for the roller, the second limiting plate is installed on both sides of the slide rail to prevent the rotating mechanism from sliding off the slide rail assembly, and the anti-slip column increases the friction between the slide rail assembly and the ground to prevent the slide rail assembly from moving relative to the ground when the rolling base is pushed under heavy load conditions.

[0015] Preferably, the rotating mechanism is provided in two sets, and the slide rail assembly and the rotating mechanism are slidably connected, the slide rail assembly and the limiting mechanism are slidably connected, and the sliding assembly is provided in two sets.

[0016] Preferably, the roller and the roller shaft are connected by bearings, and the roller shaft and the first limiting plate are interference fit, and the first limiting plate is provided in two sets.

[0017] The technical effects and advantages of this utility model are as follows: 1. Compared with existing technologies, this roller structure with a heavy-duty bidirectional limiting mechanism constructs a high-strength load-bearing system through the synergy of the rotating mechanism and the limiting mechanism. The base plate, as the basic load-bearing component, bears the overall weight of the equipment and transmits it to the limiting mechanism. The top plate of the connecting component in the limiting mechanism is specially reinforced with vertical load-bearing strength, and the fixing column of the fixing component enhances the structural rigidity in the form of core support. Combined with the lateral reinforcement of the side plate, a three-dimensional load-bearing frame is formed. At the same time, the setting of two sets of rotating mechanisms evenly distributes the heavy load pressure. The interference fit between the roller and the first limiting plate ensures that there is no loosening or displacement during the force transmission process, so that the entire structure can remain stable when subjected to large gravity, solving the problem of easy deformation of traditional single-unit load-bearing structures.

[0018] 2. Compared with the prior art, the roller structure with heavy-duty bidirectional limiting mechanism is based on the guidance of the sliding component, which enables the rotating mechanism to slide smoothly on the slide rail component. During the sliding process, the two sets of sliding components slide stably against the side of the slide rail component through the sliding plate. The firm connection between the sliding component and the fixed component drives the rotating mechanism to move horizontally on the slide rail component. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1 As attached Figures 1 to 4 The roller structure shown includes a heavy-duty bidirectional limiting mechanism, comprising a base plate 1, a limiting mechanism 2, a rotating mechanism 3, and a slide rail assembly 4. The limiting mechanism 2 is installed below the base plate 1, the rotating mechanism 3 is installed on the side of the limiting mechanism 2, and the slide rail assembly 4 is provided below the rotating mechanism 3. The limiting mechanism 2 includes a connecting component 5, a fixing component 6, and a sliding component 7. The fixing component 6 is installed on the side of the connecting component 5, and the sliding component 7 is installed on the side of the fixing component 6 away from the connecting component 5.

[0026] Specifically: When the roller structure uses the base plate 1 as the basic load-bearing component, the limiting mechanism 2 installed below it serves as the core limiting unit. It can form a stable limiting system through its own connecting component 5, fixing component 6, and sliding component 7. The rotating mechanism 3 mounted on the side of the limiting mechanism 2 provides power support for the horizontal movement of the structure. The rotating mechanism 3 cooperates with the slide rail component 4 below. Through the sliding connection between the slide rail component 4, the rotating mechanism 3, and the limiting mechanism 2, the overall structure can move smoothly along the slide rail component 4. At the same time, the setting of two sets of rotating mechanisms 3 and two sets of sliding components 7 further enhances the heavy load bearing capacity and bidirectional limiting reliability of the structure, so that each component can meet the usage requirements under heavy load conditions in collaborative work.

[0027] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the connecting assembly 5 includes a connecting plate 8, a top plate 9, and a protective plate 10. The top plate 9 is installed below the connecting plate 8, and the protective plate 10 is installed on the side of the top plate 9. The connecting plate 8 achieves a rigid connection with the base plate 1. The top plate 9 enhances the vertical load-bearing strength, and the protective plate 10 forms a closed protection, which can effectively prevent impurities from entering and parts from being bumped, thereby improving the structural durability.

[0028] In a preferred embodiment, the fixing component 6 includes a fixing column 11, a side plate 12, and a partition plate 13. The side plate 12 is installed on the outer diameter surface of the fixing column 11, and the partition plate 13 is installed on the side of the side plate 12. The fixing column 11 serves as the core support, positioning the side plate 12 and enhancing lateral stability. The partition plate 13 separates the two sets of rotating mechanisms 3 to avoid mutual interference during movement.

[0029] In a preferred embodiment, the sliding assembly 7 includes a slide plate 14, a connecting block 15, and a fixing bolt 16. The connecting block 15 is installed on the side of the slide plate 14, and the fixing bolt 16 is installed on the side of the connecting block 15 away from the slide plate 14. The slide plate 14 fits against the side of the slide rail assembly 4 to ensure smooth sliding. The connecting block 15 adapts to the installation angle to achieve a transition connection. The fixing bolt 16 fastens the sliding assembly 7 and the fixing assembly 6.

[0030] In a preferred embodiment, the rotating mechanism 3 includes a roller 17, a first limiting plate 18, and a roller 19. The first limiting plate 18 is mounted on the outer diameter surface of the roller 17, and the roller 19 is provided on the side of the first limiting plate 18. The roller 17 cooperates with the bearing to reduce the rotational friction of the roller 19. The two sets of first limiting plates 18 are symmetrically installed and limited on both sides of the roller 17, which can effectively prevent the roller 17 from shifting and adapt to stable rotation under heavy load.

[0031] In a preferred embodiment, the slide rail assembly 4 includes a slide rail plate 20, a second limiting plate 21, and an anti-slip post 22. The second limiting plate 21 is installed above the slide rail plate 20, and the anti-slip post 22 is installed below the slide rail plate 20. The slide rail plate 20 provides a stable sliding track for the roller 19, the second limiting plate 21 prevents the rotating mechanism 3 from derailing, and the anti-slip post 22 increases the friction between the slide rail and the ground.

[0032] In a preferred embodiment, the rotating mechanism 3 is provided in two sets, the slide rail assembly 4 and the rotating mechanism 3 are slidably connected, the slide rail assembly 4 and the limiting mechanism 2 are slidably connected, and the sliding assembly 7 is provided in two sets.

[0033] In a preferred embodiment, the roller 19 and the roller 17 are connected by bearings, the roller 17 and the first limiting plate 18 are interference fit, and the first limiting plate 18 is provided with two sets.

[0034] The working process of this utility model is as follows: First, when the operator pushes the equipment, the thrust is first transmitted to the base plate 1 connected to the equipment. The base plate 1 drives the limiting mechanism 2 installed below to be subjected to force synchronously. The connecting plate 8 of the connecting component 5 in the limiting mechanism 2 moves with the base plate 1 due to its rigid connection. The top plate 9 maintains structural stability while vertically bearing the weight of the equipment. The protective plate 10 always shields the internal parts to avoid external interference. In the fixing component 6 of the limiting mechanism 2, the fixing column 11 supports the side plate 12. The side plate 12 transmits the force to the rotating mechanism 3. The isolation plate 13 ensures that the two sets of rotating mechanisms 3 do not interfere with each other during movement. In the sliding component 7, which is fastened to the fixing component 6 by the fixing bolt 16, the connecting block 15 transmits power at the appropriate angle. The sliding plate 14 is close to the side of the slide rail component 4 to maintain the stability of the sliding direction.

[0035] Under the action of force, the roller 17 of the rotating mechanism 3 drives the roller 19 to roll along the slide rail plate 20 of the slide rail assembly 4 through the bearing. The two sets of first limiting plates 18, which are interference-fitted on the roller 17, restrict the lateral displacement of the roller 17. The second limiting plate 21 above the slide rail plate 20 further prevents the roller 19 from derailing. The anti-slip column 22 below the slide rail plate 20 increases the friction with the ground, keeping the slide rail assembly 4 fixed. Finally, the entire roller structure can move smoothly horizontally along the slide rail assembly 4. The above is the working principle of a roller structure with a heavy-duty bidirectional limiting mechanism.
