Description

Technical Field

[0001] The utility model relates to the technical field of TV bracket accessories, in particular to a front arm of a TV bracket. Background Art

[0002] Flat-panel televisions have become a popular audio-visual device. There are multiple ways to install and fix flat-panel televisions, among which the cantilever type is widely praised for its good installation adaptability. The cantilever type bracket usually includes a front arm and a rear arm, which are hinged.

[0003] The front arm of an existing TV stand is generally a rod or plate of fixed length, one side of which is hinged to the rear arm and the other side is fixedly connected to the TV mounting plate. However, since the length is fixed, the adjustment distance of the TV is limited, and after being hinged to the rear arm, it can only be rotated left and right, while the up and down angles cannot be adjusted, making it impossible to adjust the pitch angle of the TV and unable to meet the viewing needs at various angles. Therefore, the utility model designs a front arm of a TV stand to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides an embodiment: a front arm of a TV stand, comprising: an outer sleeve 1, a front arm mechanism 2 which can be extended and retracted to adjust the length of the outer sleeve 1, a U-shaped block 3 is provided on one side of the outer sleeve 1, and an adjustment mechanism 4 which can control the up and down angles is provided between the U-shaped block 3 and the outer sleeve 1.

[0022] See also Figure 1-2 In this embodiment: the front arm mechanism 2 includes a front arm 201, the front arm 201 is slidably mounted with the outer sleeve 1, a groove 202 is provided at the top of the front arm 201, and a plurality of through holes 203 are provided at both ends of the front arm 201, and the through holes 203 are connected with the groove 202, and through grooves 204 parallel to the through holes 203 are provided on the inner walls of both ends of one side of the outer sleeve 1, and a fixing block 205 is installed on the side of the top of the outer sleeve 1 close to the through groove 204, and slots 206 are provided below both ends of the fixing block 205, and a plug rod 207 is slidably installed in the slot 206, and the plug rod 207 is connected with the through groove 204 and the through hole 2 03 sliding connection, the ends of the tops of the two plug rods 207 that are close to each other are both installed with a lever 209, and the top of the fixed block 205 is provided with a lever groove 210 that is slidably connected to the lever 209. When the TV needs to be brought closer to the viewer, the two levers 209 can be pressed to make the two plug rods 207 approach each other and leave the through groove 204 and the through hole 203, and the front arm 201 can be pulled out to extend the distance. After extension, the plug rods 207 are moved away from each other and enter the through groove 204 and the through hole 203 again, and the front arm 201 and the outer sleeve 1 are locked. By adjusting the length, the TV can be brought closer to the viewer.

[0023] See also Figure 1-2In this embodiment: the insertion rod 207 is connected to the fixed block 205 through the spring 208, and the spring 208 is located in the slot 206. When the insertion rods 207 are close to each other, the spring 208 is squeezed. When the insertion rod 207 is released, the restoring force of the spring 208 can automatically insert the insertion rod 207 into the through groove 204 and the through hole 203, and the insertion rod 207 has a force to move away from each other, thereby improving the stability of the insertion rod 207.

[0024] See also Figure 2 In this embodiment, a cotton layer is provided above the outer wall of the lever 209, and the cotton layer improves the comfort of pressing.

[0025] See also Figure 3-5 In this embodiment: the adjustment mechanism 4 includes a rotating shaft 401, which is rotatably installed between the two ends of the U-shaped block 3. A rotating block 402 is installed on the outer wall of the rotating shaft 401. The rotating block 402 is fixedly installed on one side of the outer sleeve 1 away from the side of the U-shaped block 3. By adjusting the position of the TV up and down, the rotating block 402 can drive the rotating shaft 401 to rotate, so that the TV rotates up and down with the rotating shaft 401 as the center to change the pitch angle to meet different viewing needs.

[0026] See also Figure 3-5 In this embodiment: a rotating column 403 is installed at one end of the rotating shaft 401, and a plurality of fixing holes 404 are opened on the outer wall of the rotating column 403 at one end away from the U-shaped block 3. A connecting cylinder 405 fixedly connected to the U-shaped block 3 is provided on the outer side of the rotating column 403. A bolt 406 is installed on the upper side of the outer wall of the connecting cylinder 405 by threaded rotation. The bolt 406 is slidably connected to the fixing hole 404. After adjusting the pitch angle, the bolt 406 is turned into the fixing hole 404 to lock the angle.

[0027] Working principle: When the length of the front arm 201 needs to be extended, the two levers 209 are pressed by fingers to make the two levers 209 approach each other, driving the insertion rod 207 to leave the through hole 203 and the through slot 204 and enter the slot 206 and squeeze the spring 208. The front arm 201 can be pulled at will without any obstruction. After the front arm 201 is pulled out to extend the length, it is only necessary to align any through hole 203 with the through slot 204, release the lever 209, and through the restoring force of the spring 208, the insertion rod 207 can be driven away from each other and inserted into the through hole 203 and the through slot 204, thereby locking the front arm 201.

[0028] When it is necessary to adjust the up and down angles, hold the outer sleeve 1 with your hand, and then unscrew the bolt 406 to adjust the angle of the outer sleeve 1 up and down. Just make any fixing hole 404 parallel to the bolt 406. After adjusting the angle, insert the bolt 406 so that the bolt 406 passes through the fixing hole 404. Then, the column 403 can be locked, thereby locking the angle of the outer sleeve 1.
