[0032] Reference below Figures 1 to 6 The invention discloses a lifting device and a display stand having the lifting device according to an embodiment of the invention.

[0033] like Figures 1 to 3As shown, the lifting device according to the first embodiment of the utility model includes: a housing 100, a telescopic component 200, a sliding component 300, a rolling component 400 and a damping member 500. The front wall of the housing 100 is provided with a vertical slide groove 110; the telescopic component 200 is telescopically arranged inside the housing 100; the sliding component 300 passes through the slide groove 110 and is connected to the telescopic component 200, and can slide along the slide groove 110 through the telescopic component 200; the rolling component 400 is arranged in the housing 100 and includes at least one first rolling element 410 and at least one second rolling element 420, the first rolling element 410 and the second rolling element 420 are distributed up and down and are respectively rotatably connected to the sliding component 300, the first rolling element 410 is rollingly connected to the front wall of the shell 100, and there is a gap between the first rolling element 410 and the rear wall of the shell 100, the second rolling element 420 is rollingly connected to the rear wall of the shell 100, and there is a gap between the first rolling element 410 and the front wall of the shell 100; the damping element 500 is elastic and is arranged on the side of the sliding component 300, and abuts against the inner wall of the shell 100 to increase the sliding damping.

[0034] It can be understood that the lifting device includes a housing 100, a telescopic assembly 200, a sliding assembly 300, a rolling assembly 400 and a damping member 500. The telescopic assembly 200 is telescopically arranged in the housing 100. The sliding assembly 300 can slide along the slide groove 110 of the housing 100 through the telescopic assembly 200. Since the sliding assembly 300 passes through the slide groove 110 and is used to connect the user end, it is easy to cause the sliding assembly 300 located in the housing 100 to tilt due to the weight of the user end, so that the upper part of the sliding assembly 300 abuts against the front wall of the housing 100, and the sliding assembly 300 0 is in contact with the rear wall of the shell 100. At this time, the first rolling member 410 in the rolling assembly 400 is rollingly connected to the front wall of the shell 100, and the second rolling member 420 in the rolling assembly 400 is rollingly connected to the rear wall of the shell 100, thereby greatly reducing the friction of the sliding assembly 300. However, since an elastic damping member 500 is provided between the sliding assembly 300 and the shell 100, the user's feel during lifting and lowering adjustment can be improved, and the adjustment efficiency can be improved. Therefore, the lifting device of the present application has better friction during the adjustment process, thereby improving the user's feel.

[0035] Specifically, the damping member 500 is located between the front wall or the rear wall of the housing 100 and the sliding assembly 300 , thereby also improving the stability of the sliding assembly 300 during the sliding process.

[0036] It can be understood that the damping member 500 includes a connecting portion 510 and an arched portion 520, the connecting portion 510 is connected to the sliding assembly 300, both ends of the arched portion 520 are connected to the side of the connecting portion 510 away from the sliding assembly 300, and the middle portion of the arched portion 520 arches toward the side away from the connecting portion 510 and forms a gap with the connecting portion 510. For example, Figures 4 to 5 As shown, in this embodiment, the connecting portion 510 and the arched portion 520 of the damping member 500 are sequentially connected to the outer side of the sliding component 300, and the middle portion of the arched portion 520 is arched to form a gap with the connecting portion 510, thereby having an elastic force to deform the connecting portion 510, so that the damping member 500 located between the sliding component 300 and the housing 100 has a certain elasticity, and also increases the sliding friction of the sliding component 300.

[0037] It should be understood that the damping member 500 may also be configured as other elastic members such as a silicone block or a rubber block.

[0038] It can be understood that the connecting portion 510 is provided with a slot 511, and the side of the sliding assembly 300 is correspondingly provided with an insertion portion 310, and the damping member 500 is sleeved on the insertion portion 310 through the slot 511. Figure 5 to Figure 6 As shown, in this embodiment, the insertion portion 310 of the sliding assembly 300 is inserted into the slot 511 of the connecting portion 510 , thereby achieving connection to the damping member 500 .

[0039] It should be understood that the sliding assembly 300 may also be connected to the damping member 500 by welding, fastener connection, or the like.

[0040] It can be understood that at least two first rolling members 410 are provided, at least two second rolling members 420 are provided, and the first rolling members 410 and the second rolling members 420 are arranged at intervals in the vertical direction. Figures 2 to 3 As shown, in this embodiment, at least two first rolling elements 410 and at least two second rolling elements 420 are distributed at intervals in the vertical direction, so that during the sliding process of the sliding component 300, there is higher stability and the shaking of the sliding component 300 is reduced.

[0041] It is understandable that the front wall of the housing 100 and the inner wall of the housing 100 are both provided with a first guide rail, and the rolling assembly 400 is adapted to the first guide rail and rolls along the guide rail. For example, in this embodiment, the rolling assembly 400 rolls along the first guide rail of the inner wall of the housing 100, thereby improving the linearity of the lifting and lowering of the sliding assembly 300.

[0042] It is understandable that guide members 320 are further provided on both sides of the sliding assembly 300, and the left arm of the housing 100 and the right arm of the housing 100 are provided with second guide rails, along which the guide members 320 slide. For example, in this embodiment, the guide members 320 provided on the sliding assembly 300 also further improve the linearity of the lifting and lowering of the sliding assembly 300.

[0043] It is understandable that the guide member 320 is provided with a vertical convex strip 321, and the convex strip 321 abuts against the second guide rail. Figure 6 As shown, in this embodiment, the friction between the guide member 320 and the housing 100 can be reduced by the vertical ridges 321 of the guide member 320 .

[0044] It is understandable that the telescopic assembly 200 is a gas spring. Figure 2 As shown, in this embodiment, the telescopic component 200 is a gas spring, so that the user can move the sliding component 300 to any height, and the sliding component 300 can stay at the corresponding position for easy adjustment.

[0045] It is understandable that the middle portion of the sliding assembly 300 is hollowed out. Figure 3 As shown, in this embodiment, the middle portion of the sliding assembly 300 is hollowed out, thereby reducing the weight of the sliding assembly 300 and facilitating adjustment.

[0046] According to the second embodiment of the present invention, the display stand comprises a lifting device as in the first embodiment, and the sliding assembly 300 is used to connect the display.

[0047] It can be understood that the lifting device in the first aspect of the embodiment is adopted in this display stand, so that the friction force during the lifting and lowering adjustment process is appropriate, thereby facilitating improving the user's feel during adjustment.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
