Technical Field

[0001] This utility model belongs to the field of display device support technology, and in particular relates to a display support lifting structure. Background Technology

[0002] Currently, monitor stands on the market vary significantly due to their complex functional designs, and some existing monitor stands lack height adjustment functionality, preventing the monitor's height from being adjusted according to actual needs.

[0003] Furthermore, traditional monitor stands typically use iron parts or die-cast components with sliding rails to achieve the lifting function. This increases the number of parts and costs during the manufacturing process. In use, if the lifting structure of the monitor stand is complex and the cost is increased, it will reduce the product's competitiveness.

[0004] Therefore, a novel display support lifting structure is needed. Utility Model Content

[0005] The main purpose of this utility model is to provide a display support lifting structure to address the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0030] 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.

[0031] like Figures 1 to 8 As shown, a monitor support lifting structure includes a monitor bracket 1, a suspension assembly 2, a lifting assembly, and a support assembly. The monitor bracket 1 is used to connect the monitor. The suspension assembly 2 is fixedly connected to the monitor bracket 1. The lifting assembly is fixedly connected to the suspension assembly 2 via a first fastener 3. The lifting assembly is inserted into the support assembly and slidably connected to the support assembly along the height direction. The lifting assembly includes an inner sleeve 4, a constant force spring 5, and a constant force spring seat 8. The support assembly includes a lower sleeve 12 slidably connected to the inner sleeve 4. The constant force spring 5 includes a fixed end 6 and a movable end 7. The fixed end 6 is connected to the lower sleeve 4. The sleeve 12 is fixedly connected, and the movable end 7 is used in conjunction with the constant force spring seat 8. The movable end 7 extends into the lower sleeve 12 and is located below the constant force spring seat 8. The movable end 7 is vortex-shaped. The constant force spring seat 8 includes a base 9 fixedly installed at the bottom of the inner sleeve 4. A fixing block 10 is provided under the base 9. A limiting groove 11 that matches the shape of the movable end 7 is provided in the fixing block 10. That is, the shape of the limiting groove 11 should be adapted to the vortex shape of the movable end 7. Thus, when the constant force spring 5 is used in conjunction with the constant force spring seat 8, the lifting component can be suspended at any position along the up and down sliding direction of the support component.

[0032] The installation and usage principle of the display support lifting structure in this embodiment:

[0033] The fixed end 6 of the constant force spring 5 is fixed inside the lower sleeve 12, and the movable end 7 of the constant force spring 5 is located inside the lower sleeve 12. The constant force spring seat 8 is fixedly installed at the bottom of the inner sleeve 4, and the movable end 7 of the constant force spring 5 is engaged with the limiting groove 11 on the constant force spring seat 8. The pre-tension of the constant force spring 5 is used to keep the inner sleeve 4 in an upward state, thus completing the installation of the lifting assembly. The inner sleeve 4 is pressed down and slidably connected to the lower sleeve 12, thus restricting the inner sleeve 4 inside the lower sleeve 12, thus completing the installation of the lifting assembly and the support assembly. The installed lifting assembly is fixed to the suspension assembly 2 by the first fastener 3, thus realizing the overall installation of the display support lifting structure. In use, if it is necessary to lower the height of the lifting structure to a specified height, manually press the inner sleeve 4 downward along the sliding direction of the lower sleeve 12 to the specified height position. As the inner sleeve 4 is subjected to downward pressure and acts on the constant force spring seat 8, the limiting groove 11 of the constant force spring seat 8 cooperates with the movable end 7 of the constant force spring 5 to drive the constant force spring 5 downward. Due to the characteristics of the constant force spring 5, when the inner sleeve 4 is pressed down to the specified height position, the inner sleeve 4 immediately stops at the specified height position. When it is necessary to adjust the height of the lifting structure upward to the specified height, manually lift the inner sleeve 4 upward along the sliding direction of the lower sleeve 12 to the specified height position. Similarly, due to the characteristics of the constant force spring 5, when the inner sleeve 4 is lifted to the specified height position, the inner sleeve 4 immediately stops at the specified height position.

[0034] The fixed end 6 of the constant force spring 5 has a concave structure. Specifically, the fixed end 6 is a concave hook. The inner wall of the lower sleeve 12 is provided with a top plate 13 along the direction of the inner sleeve 4. There is a gap between the top plate 13 and the inner wall of the lower sleeve 12. The hook is snapped into the top plate 13 to fix the constant force spring 5 on the top plate 13. This eliminates the need for traditional screw fastening, reduces the number of parts used, and lowers the cost.

[0035] The inner wall of the lower sleeve 12 is provided with a plurality of sliding plates 14 along the circumferential direction of the inner sleeve 4, which abut against the outer wall of the inner sleeve 4. The end of the sliding plate 14 that contacts the inner sleeve 4 is smooth. This arrangement can ensure that the inner sleeve 4 can slide along the lower sleeve 12. Furthermore, the abutment between the sliding plate 14 and the inner sleeve 4 can ensure that the inner sleeve 4 and the lower sleeve 12 are tightly fitted together, which can prevent the inner sleeve 4 and the lower sleeve 12 from being separated due to a vacuum.

[0036] A lifting limit component is fitted around the bottom outer periphery of the inner sleeve 4. The lifting limit component is fixedly connected to the lower sleeve 12 via the second fastener 15. The lifting limit component can limit the sliding of the inner sleeve 4 along the lower sleeve 12 to ensure that the inner sleeve 4 will not detach from the lower sleeve 12 and will not affect the normal lifting action of the lifting structure.

[0037] Specifically, the lifting and limiting assembly includes a limiting ring 16 sleeved and installed at the bottom of the inner sleeve 4. A limiting plate 17 is vertically positioned at one end of the bottom of the limiting ring 16. When installing the lifting and limiting assembly, the limiting plate 17 is inserted into the gap between the top plate 13 and the inner wall of the lower sleeve 12 to fix the fixed end 6 of the constant force spring 5. Since the fixed end 6 of the constant force spring 5 is fixed on the top plate 13 inside the lower sleeve 12, and there is a certain gap between the top plate 13 and the inner wall of the lower sleeve 12, it is necessary to fill the gap to ensure that the constant force spring 5 can be securely fixed on the top plate 13. The limiting plate 17 is inserted into the gap between the top plate 13 and the inner wall of the lower sleeve 12 to fix the fixed end 6 of the constant force spring 5. The installation process of the lifting limiting assembly is as follows: the limiting ring 16 is put from the top of the inner sleeve 4 into the bottom of the inner sleeve 4, and the limiting plate 17 is inserted into the gap between the top plate 13 and the inner wall of the lower sleeve 12. Then, the limiting ring 16 is fixedly connected to the top of the lower sleeve 12 with the second fastener 15. This can also restrict the inner sleeve 4 within the lower sleeve 12 so that the inner sleeve 4 can slide up and down within the lower sleeve 12.

[0038] The lifting assembly also includes an upper sleeve 18, which is located outside the inner sleeve 4. The first fastener 3 passes through the suspension assembly 2, the top of the upper sleeve 18 and the top of the inner sleeve 4 to achieve a fixed connection between the suspension assembly 2, the upper sleeve 18 and the inner sleeve 4. The upper sleeve 18 can provide protection for the inner sleeve 4 on the one hand, and guide the lifting and lowering movement of the lifting structure on the other hand.

[0039] The inner sleeve 4 has a slot 19 near the top, and a reinforcing plate 21 is snapped into the slot 19. The reinforcing plate 21 has a connecting hole 20 that mates with the first fastener 3. Snapping the reinforcing plate 21 into the inner sleeve 4 can increase the load-bearing capacity and stability of the inner sleeve 4 and prevent the inner sleeve 4 from deforming under stress, thus affecting the structural integrity and functionality of the lifting assembly. The first fastener 3 can pass through the connecting hole 20 to further fix the reinforcing plate 21 into the inner sleeve 4.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
