Description

Technical Field

[0001] This utility model belongs to the technical field of support tension adjustment, and in particular relates to a structure and display support device for adjusting support tension. Background Technology

[0002] In the fields of modern industrial equipment and daily office and home furnishing products, support structures are widely used, such as monitor support brackets, furniture load-bearing brackets, and industrial machinery support components. Their core function is to provide stable support for the target load (such as monitors, mechanical equipment parts, furniture panels, etc.) to ensure that the load remains in a fixed position during use and is not easily deformed or tipped over.

[0003] However, existing support structures generally suffer from insufficient support tension adjustment capability or cumbersome adjustment methods: most traditional support structures adopt a fixed tension design, and their support strength is fixed during manufacturing, making it impossible to adjust according to changes in the weight of the actual load; furthermore, for some support structures with tension adjustment function, the adjustment process requires the disassembly and assembly of multiple components using specialized tools, affecting user efficiency and experience.

[0004] Therefore, there is a need to provide a structure that facilitates the adjustment of the support tension in order to achieve tension adjustment of the support panel. Utility Model Content

[0005] The main objective of this invention is to provide a structure for adjusting support tension and a display support device having the structure for adjusting support tension, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A structure for adjusting support tension includes an outer shell, a fixing block, and a cavity shell. The fixing block and the cavity shell are fixed inside the outer shell. The fixing block has a first bevel gear and a second bevel gear that are vertically meshed. The first bevel gear is disposed in the fixing block along the height direction, and the second bevel gear is disposed in the fixing block along the horizontal direction. A bolt passes through the fixing block and the first bevel gear to make the first bevel gear rotate in the fixing block and drive the second bevel gear to rotate. A threaded post is installed in the cavity shell along the horizontal direction. One end of the threaded post passes through the second bevel gear and is fixed in the fixing block. The other end of the threaded post passes through a slider disposed in the cavity shell and extends into the cavity shell. The slider is disposed at the connection joint between the fixing block and the cavity shell and rotates along the thread of the threaded post. A spring is disposed in the cavity shell. One end of the spring is fixed to the side wall of the slider, and the other end of the spring is fixed to a connector disposed in the cavity shell. The spring covers the end of the threaded post that extends into the cavity shell.

[0007] Preferably, a limiting plate is provided at the bottom of the fixing block, the bottom of the bolt is threadedly connected to the bottom plate of the limiting plate, one end of the threaded post passes through the side wall of the limiting plate, and the second bevel gear is fixed inside the fixing block.

[0008] Preferably, the bottom plate of the limiting plate is provided with a fixing plate, and the fixing plate is provided with a fixing hole that mates with the end of the threaded post that extends into the fixing block.

[0009] Preferably, the outer wall of the second bevel gear is provided with a positioning hole, one end of the threaded post passes through the second bevel gear, and is inserted into the positioning hole by a fixing member to abut against the threaded post so that the end of the threaded post passing through the second bevel gear is fixed relative to the second bevel gear.

[0010] Preferably, a groove is provided on the top of the cavity shell, and an indicator strip is fixed on the slider, the indicator strip being able to slide within the groove.

[0011] Preferably, the outer casing is equipped with a transparent plate, and a plurality of stop bars are provided in the horizontal direction on the outer side of the transparent plate. The indicator bar can be observed moving along the slide groove to the position of the corresponding stop bar through the transparent plate.

[0012] Preferably, the outer shell is fixedly connected to the fixing block and the cavity shell by a plurality of fastening screws respectively.

[0013] Preferably, the top surface of the housing is provided with a cover plate above the fixing block, and the cover plate covers the top of the bolt.

[0014] A display support device includes the structure described in any one of the preceding claims for adjusting support tension.

[0015] Compared with the prior art, the present invention will have at least the following beneficial effects: In this invention, when the bolt is tightened, the first bevel gear drives the second bevel gear to rotate, causing the slider to slide along the threaded post towards the cavity and compress the spring. The spring's reaction force increases, raising the supporting tension, making it suitable for heavy loads. When the bolt is loosened, the bevel gear reverses its rotation, causing the slider to move back towards the fixed block. The spring expands and returns to its original position, reducing the supporting tension, making it suitable for lighter loads. The entire adjustment process can be completed simply by rotating the bolt with a tool, without disassembling any parts, making the operation simple and efficient.

[0016] In this invention, the sliding groove on the top of the cavity shell and the indicator strip on the slider, together with the transparent plate of the outer shell and the outer stop strip, can form an intuitive support tension level display system. Users do not need to disassemble the structure; they can observe the corresponding positions of the indicator strip and the stop strip through the transparent plate, quickly determine whether the current support tension matches the weight requirements of the load, and improve adjustment efficiency.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0020] like Figures 1 to 9 As shown, a structure for adjusting support tension includes a housing 1, a fixing block 2, and a cavity 3. The fixing block 2 is connected to a connecting part 22 for connecting a support panel.

[0021] The fixing block 2 and the cavity shell 3 are fixed inside the outer shell 1. The outer shell 1 is fixedly connected to the fixing block 2 and the cavity shell 3 by several fastening screws 20, so that the fixing block 2 and the cavity shell 3 are simultaneously fixed inside the outer shell 1.

[0022] The fixed block 2 is equipped with a first bevel gear 4 and a second bevel gear 5 that are vertically meshed. The first bevel gear 4 is located in the fixed block 2 along the height direction, and the second bevel gear 5 is located in the fixed block 2 along the horizontal direction. A bolt 6 passes through the fixed block 2 and the first bevel gear 4 to allow the first bevel gear 4 to rotate within the fixed block 2 and drive the second bevel gear 5 to rotate. Specifically, the bolt 6 passes through the fixed block 2 and the first bevel gear 4 in sequence and is threadedly connected to both the fixed block 2 and the first bevel gear 4 respectively. During operation, the bolt 6 is rotated using a tool. The rotation of the bolt 6 drives the first bevel gear 4 to rotate along its axis in the height direction, and the rotation of the first bevel gear 4 drives the second bevel gear 5 to rotate along its axis in the horizontal direction.

[0023] A threaded post 7 is installed horizontally inside the cavity shell 3. One end of the threaded post 7 passes through the second bevel gear 5 and is fixed inside the fixing block 2. The other end of the threaded post 7 passes through the slider 8 located inside the cavity shell 3 and extends into the cavity shell 3. The slider 8 is located at the connection joint between the fixing block 2 and the cavity shell 3 and rotates along the thread of the threaded post 7. When installing the threaded post 7, one end is first passed through the second bevel gear 5 and fixed inside the fixing block 2. During operation, the first bevel gear 4 rotates, driving the second bevel gear 5 to rotate. The rotation of the second bevel gear 5 then drives the slider 8 to move back and forth along the end of the threaded post 7 that extends into the cavity shell 3.

[0024] A spring 9 is provided inside the cavity shell 3. One end of the spring 9 is fixed to the side wall of the slider 8, and the other end of the spring 9 is fixed to the connector 10 provided inside the cavity shell 3. The connector 10 is used to connect other components of the support device, such as the gripping part. The spring 9 covers the end of the threaded post 7 that extends into the cavity shell 3.

[0025] In this embodiment, the deformation of spring 9 is used to provide support tension for the support panel, thereby changing the load-bearing weight of the support panel. Specifically, the support tension is adjusted according to the weight of the display and other components that need to be installed and connected to the support panel.

[0026] When it is necessary to increase the support tension, tightening bolt 6 causes the first bevel gear 4 to rotate, which in turn drives the second bevel gear 5 to rotate. After the second bevel gear 5 rotates, it compresses the slider 8 to slide along the threaded post 7 toward the cavity shell 3. As the slider 8 slides along the threaded post 7 toward the cavity shell 3, it causes the spring 9 to undergo compression deformation. At this time, when the connecting part 22 connected to the fixed block 2 is rotated, under the action of external force, the reaction force of the spring 9 is applied to the connecting part 22, causing the connecting part 22 to generate a larger support tension. This allows the support panel connected to the connecting part 22 to bear a larger weight of components such as displays. It can be understood that the greater the compression deformation of the spring 9, the greater the reaction force it provides, and the greater the support tension obtained by the connecting part 22. Therefore, the weight that the support panel connected to the connecting part 22 can bear is also greater.

[0027] When it is necessary to reduce the support tension, loosening bolt 6 causes the first bevel gear 4 to rotate in the opposite direction to that of tightening bolt 6, which in turn drives the second bevel gear 5 to rotate in the opposite direction. After the second bevel gear 5 rotates in the opposite direction, it causes the slider 8 to slide back along the threaded post 7 towards the fixed block 2. As the slider 8 slides along the threaded post 7 towards the fixed block 2, it causes the spring 9 to expand and return to its original position. At this time, when the connecting part 22 connected to the fixed block 2 is rotated, under the action of external force, the reaction force of the spring 9 is applied to the connecting part 22, which reduces the support tension of the connecting part 22. This allows the support panel connected to the connecting part 22 to support components such as displays with a smaller weight. Similarly, it can be understood that the greater the expansion and return deformation of the spring 9, the smaller the reaction force it provides, and the smaller the support tension obtained by the connecting part 22. Therefore, the weight that the support panel connected to the connecting part 22 can support is also smaller. A limiting plate 11 is provided at the bottom of the fixed block 2. The bottom of the bolt 6 is threadedly connected to the bottom plate of the limiting plate 11. One end of the threaded post 7 passes through the side wall of the limiting plate 11 and is fixed inside the fixed block 2. A fixing plate 12 is provided on the surface of the bottom plate of the limiting plate 11. A fixing hole 13 is provided on the fixing plate 12 to mate with the end of the threaded post 7 that extends into the fixed block 2. This allows the bolt 6 to rotate inside the fixed block 2, avoiding the phenomenon of the bolt 6 spinning freely, which would prevent the rotation direction of the first bevel gear 4 from being properly adjusted. In addition, this allows one end of the threaded post 7 to be fixed to the fixed block 2, and the other end to pass stably through the slider 8 that is threadedly connected to it and extend into the cavity shell 3.

[0028] The outer wall of the second bevel gear 5 is provided with a positioning hole 14. One end of the threaded post 7 passes through the second bevel gear 5 and is abutted against by a fixing member 15 inserted into the positioning hole 14, so that the end of the threaded post 7 passing through the second bevel gear 5 is relatively fixed to the second bevel gear 5. After one end of the threaded post 7 passes through the second bevel gear 5, the fixing member 15 is inserted into the positioning hole 14 so that the fixing member 15 abuts against the threaded post 7. In this way, the threaded post 7 and the second bevel gear 5 can be relatively fixed. Usually, positioning holes 14 are symmetrically opened on both sides of the outer wall of the second bevel gear 5. Inserting both sides into the positioning holes 14 at the same time can enhance the relative fixing effect between the second bevel gear 5 and the threaded post 7.

[0029] The top of the cavity shell 3 has a sliding groove 16, and an indicator strip 17 is fixed on the slider 8. The indicator strip 17 can slide within the sliding groove 16. The outer shell 1 is equipped with a transparent plate 18, and several stop strips 19 are arranged horizontally on the outer side of the transparent plate 18. Through the transparent plate 18, it is possible to observe the indicator strip 17 moving along the sliding groove 16 to the position of the corresponding stop strip 19. The stop strips 19 can be set with different positions according to the required support tension. In actual operation, the position of the indicator strip 17 and the slider 8 is synchronized along the thread of the threaded column 7. The appropriate position can be selected according to the weight that the actual support panel needs to bear. Then, the support tension is adjusted according to the position of the stop strip 19 at the corresponding position. The bolt 6 is tightened or loosened in the operation method described above to complete the adjustment of the support tension. During this process, the transparent plate 18 is transparent, and the user can directly observe the indicator strip 17 sliding along the sliding groove 16 to the position of the stop strip 19 through the transparent plate 18 to judge whether the support tension meets the actual requirements without disassembling and readjusting the support device, thus improving the user's efficiency.

[0030] The top surface of the outer casing 1 is provided with a cover plate 21 above the fixing block 2. The cover plate 21 covers the top of the bolt 6. By opening the cover plate 21, the user can directly adjust the bolt 6 by tightening or loosening it. In addition, the cover plate 21 can also protect the top of the bolt 6 to prevent other contaminants from adhering to the bolt 6 and affecting its function.

[0031] This embodiment also provides a display support device with the structure of the present invention for adjusting the support tension. The support device includes a support panel, a connecting part 22 connected to the support panel, and a support part connected to the connector 10, etc. The support panel is used to install and connect the display and other components.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
