Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the device or element referred to must have the specific orientation, operate in the specific orientation configuration, and thus, should not be construed as limiting the present invention.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides a screen stand including a sliding mechanism, a support 3, and a base 4.

Referring to fig. 2 to 5, the slide mechanism includes a holder body 1 and a slide portion 2. The bracket body 1 is provided with a sliding channel 101. The sliding part 2 is located in the sliding channel 101, at least one side surface of the sliding part close to the inner wall of the sliding channel 101 is provided with a plurality of sliding bosses 201, and the sliding bosses 201 are abutted against the inner wall of the sliding channel 101 and are connected with the inner wall of the sliding channel 101 in a sliding manner along the sliding channel 101. The lower end of the bracket body 1 is inserted into the base 4.

It can be understood that, 2 spare of traditional ball guide rail formula sliding part relatively, the utility model provides a support body 1 and sliding part 2 need not the ball structure to can break away from the restriction of ball diameter, can also be corresponding save metal guide, finally satisfy frivolous design demand, be favorable to making the screen support more frivolous.

One end of the support 3 is positioned in the sliding channel 101, and the other end extends to the outside of the sliding channel 101 to be connected with a display screen; the sliding part 2 is fixedly arranged on the side surface of the supporting part 3 close to the inner wall of the sliding channel 101.

It will be appreciated that the display screen is fixed to the support member 3 and the height of the screen can be adjusted by sliding the support member 3 up and down. Because the volume of sliding part 2 and support body 1 can be done very little, the quality is also very light, so use the utility model provides a screen support that sliding mechanism made also possesses frivolous advantage.

Referring to fig. 2, the side surface of the sliding boss 201 close to the inner wall of the sliding channel 101 is an arc surface, and the arc surface is tangent to the inner wall of the sliding channel 101. Alternatively, referring to fig. 3, a part or all of the circular arc surface may be replaced by a hemispherical surface. When the arc surface is tangent to the sliding channel 101, the arc surface and the sliding channel are in line contact, and when the hemisphere surface is tangent to the sliding channel 101, the arc surface and the sliding channel are in point contact. The point contact and the line contact can effectively reduce the contact area compared with the surface contact, thereby reducing the sliding resistance.

The utility model replaces the traditional rolling friction with the sliding friction, in order to reduce the sliding resistance, the outer side surface of the sliding boss 201 is set to be an arc surface, under the general condition, the sliding boss 201 is in line contact with the inner wall of the sliding channel 101, the contact area can be greatly reduced, and the sliding resistance is reduced; even if the deformation amount of the sliding boss 201 caused by abutting against the bracket body 1 is large, the sliding boss 201 is in surface contact with the inner wall of the sliding channel 101, and due to the design of the plurality of sliding bosses 201, the contact area between a single sliding boss 201 and the sliding channel 101 is not large. In other words, the sliding resistance is increased appropriately, and a large size reduction amount and a large weight reduction amount can be exchanged, thereby having a high market value. Further, the maximum static friction force can be properly increased, so that the sliding part 2 can conveniently stay at any position of the support body 1, and the requirement of position adjustment of the screen support is met.

Optionally, the sliding part 2 is made of plastic. Further, the sliding part 2 is an integrally molded structure formed by injection molding.

In general, plastic materials are easy to process, and parts with small size and volume and complex shape and structure can be manufactured by injection molding and other methods. The sliding part 2 that this embodiment provided is equipped with a plurality of slip bosss 201, and the curved surface is more and the shape is complicated, through technology production such as moulding plastics both can reduce the size, and the reduction in weight can also reduce the production degree of difficulty, control manufacturing cost.

In this embodiment, the sliding bosses 201 on different sides of the sliding portion 2 have different diameters. Further, the axes of the sliding bosses 201 located on the adjacent both side surfaces of the sliding portion 2 are not coplanar.

Specifically, the sliding bosses 201 with different diameters and non-coplanar axes can provide support at multiple locations, which is beneficial to ensure smoothness and stability of the sliding part 2 when sliding in the sliding channel 101.

Optionally, the screen bracket further includes a constant force spring 5, the constant force spring 5 is located in the sliding channel 101 and fixed on the support member 3, and the telescopic end of the constant force spring is fixedly connected with the bracket body 1.

Specifically, the constant force spring 5 is mainly used for providing a supporting force for positioning the display screen. Since there is no need to provide large-volume components such as slide rails and balls in the slide passage 101, a space for storing the constant force spring 5 can be made free.

It can be understood that the sliding mechanism provided by the embodiment can be applied to not only a screen bracket, but also other mechanical equipment needing to use the sliding part 2, so as to achieve the purpose of reducing the volume and the mass of the equipment.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
