Description

Technical Field

[0001] This invention relates to a folding and lifting base for a monitor and its method of use. Background Technology

[0002] Existing monitor lift stands consist of a base, a support arm, and a monitor adapter plate. The support arm is detachably connected to the base with bolts, and the support arm contains a lifting assembly that drives the monitor adapter plate to move up and down. To ensure stable support for the monitor, the bases of existing monitor lift stands are typically plate-shaped or disc-shaped, with dimensions much larger than the cross-sectional dimensions of the support arm. This results in a large volume, takes up considerable space, and incurs high packaging costs. Furthermore, the base and support arm must be disassembled during factory packaging or storage, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a folding and lifting stand for a monitor and a method for using it.

[0004] The solution adopted by this invention to solve the technical problem is a folding and lifting stand for a monitor, including a base, a support arm mounted on the base, a monitor adapter plate mounted on the upper part of the support arm via a lifting assembly, two long front support legs symmetrically mounted on the left and right sides of the front of the base, and a short rear support leg mounted in the middle of the rear of the base. Both the long front support legs and the short rear support legs are hinged to the base. The base is provided with limiting components to fix the short rear support legs in the unfolded support state and the folded storage state. A rotating shaft is vertically mounted inside the base, and a knob for driving the rotating shaft to rotate is mounted at the lower end of the base. The knob is fixedly mounted at the lower end of the rotating shaft. Two limiting protrusions are symmetrically arranged on the outer periphery of the middle of the rotating shaft. A locking arm that cooperates with the limiting protrusions is provided at the inner end of the long front support legs. When the long front support legs are in the unfolded support state, their lower sides abut against the locking arms after the limiting protrusions rotate into position. When the long front support legs are in the folded storage state, their upper sides abut against the locking arms after the limiting protrusions rotate into position.

[0005] Furthermore, the angle between the two long-arm front legs and the angle between each long-arm front leg and the short-arm rear leg are both 60 degrees.

[0006] Furthermore, the base has two symmetrical connecting ears on its rear side, and the inner end of the short arm rear support leg has a shaft hole. The inner end of the short arm rear support leg is hinged to the base via a pin that passes through the connecting ears and the shaft hole.

[0007] Furthermore, the limiting component includes ring A and ring B, both of which are fitted onto the pin. Ring A and ring B are in contact with each other. Ring A is fixedly connected to the connecting ear, and ring B is fixedly connected to the pin. Ring A has an upper limiting recess and a lower limiting recess on its contact surface with ring B. Ring B has a locking part on its contact surface with ring A. When the short arm rear support leg is in the unfolded support state and the folded storage state, the locking part is respectively locked into the upper limiting recess and the lower limiting recess.

[0008] Furthermore, a rotating seat is installed at the inner end of the front outrigger of the long arm, the rotating seat is hinged to the base, and the clamping arm is installed on the rotating seat.

[0009] Furthermore, ball heads are provided at the lower outer ends of the long arm front support leg and the lower outer ends of the short arm rear support leg, and support pads are installed at the ball heads for hinge connection.

[0010] Furthermore, the base is cylindrical or spherical.

[0011] Furthermore, the inner end of the short arm rear support leg is provided with an upper locking part, and an upper protrusion is provided on the upper side between the two limiting protrusions on the outer periphery of the rotating shaft. When the short arm rear support leg is in the unfolded supporting state, the upper side of the upper protrusion abuts against the upper locking part after rotating into position. When the short arm rear support leg is in the folded storage state, the outer side of the upper protrusion abuts against the upper locking part after rotating into position.

[0012] How to use a monitor folding and height-adjustable stand:

[0013] Folding and storage: Place the long arm front support leg and the short arm rear support leg into position, then turn the knob to the locking position to lock the long arm front support leg and the short arm rear support leg.

[0014] Expand support: Turn the knob to the unlock position to expand the front outrigger of the long arm and the rear outrigger of the short arm into place. Then turn the knob to the locking position to lock the front outrigger of the long arm and the rear outrigger of the short arm.

[0015] Compared with the prior art, the present invention has the following advantages: simple structure, reasonable design, foldable, the support legs and base do not need to be disassembled and assembled, convenient storage and packing, small area occupied, reducing packaging costs, and at the same time, it can provide stable support for the display, thus having good social and economic benefits.
