Description

Mobile TV Stand

technical field

The utility model relates to a mobile TV stand.

Background technique

TV is one of the most commonly used mechanical and electrical products in people's daily life. At present, in terms of fixed installation of TV, flat-panel TV generally adopts wall-mounted installation, but this installation method is cumbersome and inconvenient to change the position. However, most of the supports of existing TV racks cannot be lifted or adjusted in height. Even if some TV racks have been designed as liftable supports, the lifting structure is too complicated and the effect is not satisfactory.

Utility model content

The technical problem to be solved by the utility model is to provide a mobile TV stand with a liftable bracket, a simple and practical lifting structure, and convenient and safe use.

In order to solve the above technical problems, the technical solution provided by the utility model is: to make the installation and placement of the TV set more stable and safe, to ensure the service life of the TV stand, and to improve the quality of the TV set.

A mobile TV rack, comprising a bracket with wheels on the bottom and a TV hanger on the upper part of the bracket, the bracket also includes a base and a support rod, and the support rod includes a first support rod and a The second support rod is slidingly fitted in the first support rod, and a locking device for locking them is provided between the first support rod and the second support rod.

Compared with the prior art, the utility model has the advantages that: the utility model realizes the expansion and contraction of the support rod, that is, the lifting of the bracket to adjust the height of the TV frame through the mutual cooperation of the first support rod, the second support rod and the locking device. The lifting structure is simple and practical, the operation is convenient, and the safety is high; and the structure is more stable by using the first support rod and the second support rod.

The top of the first support rod is provided with an open slot; the locking device includes a first locking clip fitted on the outer periphery of the second supporting rod and a second locking clip fitted on the outer periphery of the first supporting rod. The first locking clip and the second locking clip are integrally formed. The first locking clip is used to lock the second support rod, and the second locking clip is used to lock the first support rod. Since the diameters of the first support rod and the second support rod are different, the first locking clip and the second support rod are different in diameter. A step is formed at the joint of the two locking clips, and the step portion just abuts against the upper end of the first support rod, so that the positions of the two are fixed. The locking device has a simple structure and a good locking effect.

One end of the first locking clip is located on one side of the second support rod, and the other end surrounds the second support rod, so that the middle part of the first locking clip is bent to form a collar for clamping the second support rod, Both ends of the first locking clip are fixed by tightening bolts; one end of the second locking clip is located on one side of the first support rod, and the other end surrounds the first support rod, so that the second locking clip The middle part is bent to form a ferrule for clamping the first support rod, and the two ends of the second locking clip are fixed by tightening bolts; the middle parts of the first locking clip and the second locking clip are fixed to each other . By tightening the two ends of the second locking clip, so that the first support rod and the second support rod are relatively fixed, and tightening the two ends of the first locking clip, double protection can be achieved. Specifically, even if the second lock Clamping failure, because the first locking clip and the middle part of the second locking clip are fixed to each other, the step part just abuts against the upper end of the first support rod, which can still prevent the second support rod from slipping.

A radial safety pin is provided on the second support rod between the TV hanger and the locking device, and both ends of the safety pin extend out of the second support rod. The second support rod and the first support rod are relatively fixed by the locking device, but in the case of failure of the locking device, the second support rod slides down, and setting a safety pin can play a protective role, so that the second support rod can slide at most To the position of the safety pin, it can prevent the TV hanger and the TV from being damaged due to impact.

There are two supporting rods, the two supporting rods are parallel to each other and a connecting rod is fitted between them. This structure can effectively increase the overall strength of the TV stand.

The base includes outriggers and connecting blocks for detachably connecting the support rods to the outriggers, and the bottom of the outer ends of the outriggers are detachably provided with wheels with brakes. Most of the existing bases are not detachable, and the legs are long, which wastes space when packing. The utility model connects the support bar and the base detachably, and the legs of the base are detachably connected with the wheels, which is easy to assemble. When a single part is damaged, it is easy to replace, saves packing space and is convenient to carry.

The TV hanger includes a mounting base plate and two mounting bars arranged on the mounting base plate, and the top of the mounting base plate is provided with a plurality of limiting slots for limiting the lateral movement position of the mounting bar on the mounting base plate. The utility model is provided with several limit slots on the top of the installation substrate, and the installation frame is snapped into the limit slots to limit the horizontal movement position of the installation bar on the installation substrate. When the TV set is installed on the installation frame, the TV set will not be moved at will. , Avoid problems such as tilting and unstable center of gravity, make the TV set stable and safe, improve viewing quality; avoid damage to the installation substrate, and ensure the service life of the TV stand.

The limiting groove is symmetrical along the middle of the top of the mounting substrate. This structure can ensure that the installation frame is symmetrical along the middle of the top of the installation substrate, and ensure that the TV is placed absolutely in the middle of the installation substrate, making it more stable and safe.

Both sides of the lower part of the installation strip are provided with connecting plates, and there is a buckle between the connecting plates that can move up and down along the installation strip and is used to engage and fix the lower part of the installation substrate. spring. This structure can artificially move the horizontal position of the installation strips, and the distance between the two installation strips can be adjusted according to the size of the TV set.
