Description

A base for a display Technical Field

[0001] The present invention relates to the technical field of base design, and in particular to a base for a display. Background Art

[0002] In recent years, with the impact of tablets and smartphones, televisions have evolved from desktop models to ultra-thin flat-panel TVs, and then to high-end 4K large-screen TVs. Consequently, TV bases have become an essential component. Driven by national environmental protection priorities and declining manufacturing costs, TV bases are trending towards stylish, lightweight, and simple designs that complement modern home decor. This not only reduces material consumption but also production costs, but also presents new functional requirements. Most TV bases on the market are single-function, load-bearing bases, unable to accommodate a wide range of screen sizes. With increasingly personalized home decor and larger TV screen sizes, traditional load-bearing bases lack anti-tilt functionality. For safety reasons, consumers often opt for wall-mounted bases. However, these structural limitations lead to high costs, installation difficulties, wall damage, and unremovable features. Technical issues

[0003] In order to solve the problem that the existing base can only meet the support requirements of a single product, the present invention provides a base for a display, which can adjust the fixing force of the base to meet the support requirements of displays of various sizes. Technical Solutions

[0004] The technical solution is as follows: a base for a display, which includes a bottom plate, a suction cup installed at the lower part of the bottom plate, and is characterized in that a suction cup mounting groove is provided at the lower part of the bottom plate, the suction cup includes a large suction cup and a small suction cup, and a sealing plate, the small suction cup, a suction cup fixing plate, the large suction cup, and a support plate are respectively provided in the suction cup mounting groove from bottom to top, a small suction cup through hole is provided on the small suction cup, a large suction cup through hole is provided on the large suction cup, an intermediate through hole corresponding to the small suction cup through hole and the large suction cup through hole is provided on the suction cup fixing plate, an upper through hole corresponding to the intermediate through hole is also provided on the large suction cup, and a knob is installed on the support plate, and two ventilation grooves are provided on the knob corresponding to the large suction cup through hole and the upper through hole, respectively.

[0005] Its further feature is that a mask is provided on the bottom plate; a clearance hole is provided on the bottom plate for allowing the knob to pass through, and the inner diameter of the clearance hole is larger than the outer diameter of the knob; the large suction cup includes a large plate body and a large plate sealing ring, the large plate body is provided with a step ring, the large suction cup through hole is provided on the step ring, and the upper through hole is provided on the large plate body; the small suction cup includes a small plate body and a small plate sealing ring, the small plate sealing ring is provided with a groove connected to the small plate body, the small suction cup through hole is provided in the groove, and the sealing plate is fixed in the small plate body. Beneficial effects

[0006] After adopting the present invention, since a large suction cup and a small suction cup are provided, a knob is used to control the opening and closing of the small suction cup through hole and the large suction cup through hole. When the small suction cup through hole and the large suction cup through hole are all connected, there is no suction force. When only the small suction cup through hole is connected, only the large suction cup plays an adsorption role. When both the small suction cup through hole and the large suction cup through hole are not connected, the large and small suction cups play an adsorption role at the same time to achieve the strongest suction effect. The fixing strength of the base can be adjusted as needed to meet the support requirements of monitors of various sizes. BRIEF DESCRIPTION OF THE DRAWINGS

Modes for Carrying Out the Invention

[0008] As shown in Figures 1 to 7, a base for a display includes a bottom plate 1, a suction cup mounting groove 2 for mounting a suction cup is provided at the lower portion of the bottom plate 1, the suction cup includes a large suction cup 3 and a small suction cup 4, and a sealing plate 5, a small suction cup 4, a suction cup fixing plate 6, a large suction cup 3, and a support plate 7 are respectively provided in the suction cup mounting groove 2 from bottom to top, a small suction cup through hole 8 is provided on the small suction cup 4, a large suction cup through hole 9 is provided on the large suction cup 3, an intermediate through hole 10 corresponding to the small suction cup through hole 8 is provided on the suction cup fixing plate 6, and the large suction cup 3 is further provided with an upper through hole 11 corresponding to the intermediate through hole 10, a knob 12 is installed on the support plate 7, and the knob 12 is provided with two ventilation grooves 13 corresponding to the large suction cup through hole 9 and the upper through hole 11, respectively, and the arc length between the upper ends of the two ventilation grooves 13 is smaller than the arc length between the lower ends.

[0009] The large suction cup 3 includes a large disc body 3-1 and a large disc sealing ring 3-2. The large disc body 3-1 is provided with a step ring 3-3. The large suction cup through hole 9 is opened on the step ring 3-3, and the upper through hole 1 is opened on the large disc body 3-1; the small suction cup 4 includes a small disc body 4-1 and a small disc sealing ring 4-2. The small disc sealing ring 4-2 is provided with a groove 4-3 connected to the small disc body 4-1. The small suction cup through hole 8 is opened in the groove 4-3. The sealing plate 5 is fixed in the small disc body 4-1. The sealing plate 5, the small suction cup 4, the suction cup fixing plate 6, the large suction cup 3, and the support plate 7 are all provided with mounting holes 14 and are fixed to the bottom of the base plate 1 by screws 15.

[0010] Since the large suction cup through hole 9 is connected to one of the middle through holes 10, and the small suction cup through hole 8 is connected to the other middle through hole 10 and the upper through hole 11, when the knob 12 is rotated to the 2nd position as shown in Figure 1, the large suction cup through hole 9 and the upper through hole 11 are both blocked. At this time, both the large suction cup 3 and the small suction cup 4 can be squeezed to generate suction, which is the maximum suction state; when the knob 12 is rotated to the 1st position, the vent groove 13 is connected to the large suction cup through hole 9, and the large suction cup 3 is connected to the atmosphere, and no suction is generated, while the upper through hole 11 is still blocked, and only the small suction cup 4 generates suction alone, which is a smaller suction state; when the knob 12 is rotated to the 0th position, the large suction cup through hole 9 and the upper through hole 11 are respectively connected to the two vent grooves 13, and neither the large suction cup 3 nor the small suction cup 4 generates suction, and the entire seat can be moved.

[0011] A clearance hole is provided on the base plate 1 for the knob 12 to pass through. The inner diameter of the clearance hole is larger than the outer diameter of the knob 12 so that the vent groove 13 can be connected to the atmosphere; a decorative mask 16 is provided on the base plate 1.

[0012] In order to reduce the friction between the knob 12 and the large suction cup 3, a layer of smooth release paper is adhered to the upper surface of the large suction cup 3. Both the large suction cup 3 and the small suction cup 4 are made of silicone material.

[0013] The base plate 1 is also provided with a slot for installing a USB extender 17 .
