Description

Technical Field

[0001] This invention relates to the field of base design technology, specifically to a base for a display. Background Technology

[0002] In recent years, the rise of tablets and smartphones has driven the evolution of televisions from desktop TVs to ultra-thin flat-screen TVs, and then to high-end 4K large-screen TVs. Simultaneously, TV stands have become an indispensable aesthetic component. Influenced by national emphasis on environmental protection and declining manufacturing costs, TV stands are trending towards stylish, thin, and simple designs that complement modern home décor. This not only reduces material consumption but also lowers production costs, but also places new demands on their functionality. Most TV stands on the market are single-function load-bearing stands; one stand cannot simultaneously accommodate the universal requirements of various screen sizes. As home decoration becomes increasingly personalized and TV screens grow larger, traditional load-bearing stands cannot provide anti-tilt functionality. For safety, customers often opt for wall-mounted stands. However, wall-mounted stands have drawbacks such as high price, difficulty in installation, need to damage walls, and limited mobility due to structural limitations. Summary of the Invention

[0003] To address the issue that existing bases can only support a single product, this invention provides a monitor base that allows for adjustment of the base's fixing force to meet the support needs of monitors of various sizes.

[0004] The technical solution is as follows: A display stand includes a base plate, on the lower part of which a suction cup is installed. The base plate has a suction cup mounting groove at its lower part. The suction cup includes a large suction cup and a small suction cup. From bottom to top, a sealing plate, the small suction cup, a suction cup fixing plate, the large suction cup, and a support plate are respectively arranged in the suction cup mounting groove. The small suction cup has a small suction cup through hole, and the large suction cup has a large suction cup through hole. The suction cup fixing plate has a central through hole corresponding to the small and large suction cup through holes. The large suction cup also has an upper through hole corresponding to the central through hole. A knob is installed on the support plate, and the knob has two vent grooves corresponding to the large suction cup through hole and the upper through hole, respectively.

[0005] A further feature is that a face mask is provided on the base plate;

[0006] The base plate has a clearance hole for the knob to pass through, and the inner diameter of the clearance hole is larger than the outer diameter of the knob.

[0007] The large suction cup includes a large disk body and a large disk sealing ring. The large disk body is provided with a stepped ring. The large suction cup through hole is opened on the stepped ring, and the upper through hole is opened on the large disk body.

[0008] The small suction cup includes a small disc body and a small disc sealing ring. The small disc sealing ring has a groove that communicates with the small disc body. The small suction cup through hole is opened in the groove. The sealing plate is fixed to the small disc body.

[0009] With this invention, a large and a small suction cup are provided. A knob is used to control the opening and closing of the small and large suction cup through holes. When both the small and large suction cup through holes are open, there is no suction force. When only the large suction cup through hole is open, only the small suction cup has an adsorption effect. When neither the small nor the large suction cup through hole is open, both the large and small suction cups have an adsorption effect, achieving the strongest suction effect. The fixing force of the base can be adjusted as needed to meet the support requirements of various sizes of monitors. Attached Figure Description

[0016] Figure 7 A diagram showing the installation of the knob (the knob cover is omitted). Detailed Implementation

[0017] See Figures 1 to 7As shown, a display stand includes a base plate 1. The lower part of the base plate 1 has a suction cup mounting groove 2 for mounting suction cups. The suction cups include a large suction cup 3 and a small suction cup 4. From bottom to top, 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 arranged in the suction cup mounting groove 2. The small suction cup 4 has a small suction cup through hole 8, and the large suction cup 3 has a large suction cup through hole 9. The suction cup fixing plate 6 has a middle through hole 10 corresponding to the small suction cup through hole 8. The large suction cup 3 also has an upper through hole 11 corresponding to the middle through hole 10. A knob 12 is installed on the support plate 7. The knob 12 has two vent grooves 13 that correspond to the large suction cup through hole 9 and the upper through hole 11, respectively. The arc length between the upper ends of the two vent grooves 13 is less than the arc length between their lower ends.

[0018] The large suction cup 3 includes a large plate body 3-1 and a large plate sealing ring 3-2. The large plate body 3-1 is provided with a stepped ring 3-3. The large suction cup through hole 9 is opened on the stepped ring 3-3, and the upper through hole 1 is opened on the large plate body 3-1. The small suction cup 4 includes a small plate body 4-1 and a small plate sealing ring 4-2. The small plate sealing ring 4-2 is provided with a groove 4-3 that connects to the small plate 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 plate 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.

[0019] Because the large suction cup through-hole 9 is connected to one of the intermediate through-holes 10, and the small suction cup through-hole 8 is connected to the other intermediate through-hole 10 and the upper through-hole 11, when the knob 12 is turned to the position shown... Figure 1 When the knob is turned to position 2, both the large suction cup through hole 9 and the upper through hole 11 are 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 is turned to position 1, the ventilation 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 longer generates suction. The upper through hole 11 is still blocked, and only the small suction cup 4 generates suction. At this time, the suction state is relatively small. When the knob is turned to position 0, the large suction cup through hole 9 and the upper through hole 11 are connected to the two ventilation grooves 13 respectively. Neither the large suction cup 3 nor the small suction cup 4 generates suction. At this time, the entire seat can be moved.

[0020] The base plate 1 has a clearance hole 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 ventilation groove 13 can communicate with the atmosphere. A decorative mask 16 is provided on the base plate 1.

[0021] To reduce friction between the knob 12 and the large suction cup 3, a layer of smooth release paper is attached 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.

[0022] The base plate 1 also has a slot for mounting a USB extender 17.
