Fig. 9 is an enlarged schematic view of the region B in fig. 3, as shown in fig. 9, after the first pipe fitting 205 and the second pipe fitting 206 are assembled with each other, the second connection portion 310 and/or the first connection portion 307 penetrate the fixing plate 201, the first limiting portion 306 and the second limiting portion 311 respectively abut against two opposite side surfaces of the fixing plate 201, and the fixing plate 201 is clamped by the first limiting portion 306 and the second limiting portion 311 together, so as to achieve relative fixation between the fixing plate 201 and the connection beam 202.

The fixing plate 201 has a shape as shown in fig. 15, and the fixing plate 201 includes a base 505, a first burring 503, and a second burring 504. The base portion 505 is connected to the first burring portion 503 and the second burring portion 504 at both ends in the longitudinal direction of the connecting beam 202, respectively, and the base portion 505 is plate-shaped, and the first burring portion 503 and the second burring portion 504 protrude from the base portion 505 in the thickness direction of the base portion 505. In fig. 15, the thickness direction of the base 505 is the front-rear direction, and the longitudinal direction of the connection beam 202 is the left-right direction (connection beam is not shown in fig. 15). The first burring 503 and the second burring 504 are each provided with a mounting hole 309, and the above-mentioned "the second connecting portion 310 and/or the first connecting portion 307 is/are provided through the fixing plate 201" may specifically be one of the following three cases: (1) The first connection portion 307 is inserted into the mounting hole 309 of the first burring portion 503, and the second connection portion 310 is inserted into the mounting hole 309 of the second burring portion 504; (2) The second connection portion 310 is simultaneously inserted through the mounting hole 309 of the first flanging portion 503 and the mounting hole 309 of the second flanging portion 504, and the second connection portion 310 is sleeved outside the first connection portion 307 (as shown in fig. 9); (3) The first connection portion 307 is inserted through the mounting hole 309 of the first flange portion 503 and the mounting hole 309 of the second flange portion 504 at the same time, and the first connection portion 307 is sleeved outside the second connection portion 310.

As shown in fig. 9, the first limiting portion 306 abuts against the first flange portion 503, and the second limiting portion 311 abuts against the second flange portion 504, so that the first limiting portion 306 and the second limiting portion 311 clamp the fixing plate 201. More specifically, a side surface of the first burring 503 facing away from the second burring 504 is configured to abut against the first limiting portion 306, and a side surface of the second burring 504 facing away from the first burring 503 is configured to abut against the second limiting portion 311. The base 505 is used for connection with the connection arm assembly 102, and the first burring 503 and the second burring 504 are portions penetrated by the connection beam 202 and clamped together by the first stopper 306 and the second stopper 311. The mounting plate 201 shown in fig. 15 facilitates connection of the connection arm assembly 102 and the connection beam 202 to the mounting plate 201.

Next, how to assemble the first pipe 205, the second pipe 206, and the fixing plate 201 with each other and disassemble the three from each other will be described. The process of assembling the first tube 205, the second tube 206 and the fixing plate 201 is generally as follows (the clip 304 has been previously assembled with the first tube 205): the user inserts the second connecting portion 310 into the fixing plate 201, and makes the second limiting portion 311 contact with the fixing plate 201; then, the user inserts the first connection portion 307 into the second connection portion 310, and brings the first stopper 306 into abutment with the fixing plate 201; next, the user fixes the first and second connection portions 307 and 310 to each other by using the locking structure, so that the first and second pipe members 205 and 206 are relatively fixed and the first and second stopper portions 306 and 311 are maintained in a state capable of clamping the fixing plate 201. Conversely, the process of disassembling the first pipe member 205, the second pipe member 206, and the fixing plate 201 is approximately as follows: the user firstly releases the locking structure to lock the first connection portion 307 and the second connection portion 310, then withdraws the first connection portion 307, and withdraws the second connection portion 310 from the fixing plate 201.

The panel assembly 103 of the present invention is convenient to transport and store. When the panel assembly 103 is required to be transported or stored, a user may detach the fixing plate 201 and the connection beam 202 from each other and detach the first pipe 205 and the second pipe 206 of the connection beam 202 from each other. As shown in fig. 2, when the panel assembly 103 is not disassembled, the space occupied by the panel assembly 103 is relatively large (e.g., there is a space between two connection beams 202), and the required volume of the package is also large. And after the fixing plate 201 and the connection beam 202 are disassembled and the first and second pipe members 205 and 206 are disassembled, the user can more compactly put the disassembled parts together to reduce the space required for the storage of the panel assembly 103 and to reduce the volume of the package. The reduced space required for storage and the reduced volume of the package facilitate reduced transportation costs. Accordingly, the components of the panel assembly 103 of the present invention can be disassembled for storage to reduce the space required for storage and the volume of packaging required, and the panel assembly 103 is convenient for storage and transportation.

In addition, the panel assembly 103 of the present invention is highly convenient to assemble and disassemble. Specifically, after the first pipe fitting 205 and the second pipe fitting 206 are fixed by the locking structure, the first limiting portion 306 and the second limiting portion 311 clamp the fixing plate 201, and the connection beam 202 and the fixing plate 201 are also fixed to each other. Therefore, the fixing plate 201 and the connecting beam 202 are not required to be fixed by screws, and the assembling and disassembling between the connecting beam 202 and the fixing plate 201 do not need a user to screw the screws, so that the panel assembly 103 has high assembling and disassembling convenience.

In some embodiments, the locking structure is provided as a resilient locking structure comprising a catch 304 and a snap hole 303. The fact that the locking structure is arranged to be an elastic locking structure means that the first connecting portion 307 and the second connecting portion 310 are not required to be connected through screws, a user does not need to drive screws in the process of assembling the first pipe fitting 205 and the second pipe fitting 206 or disassembling the connecting beam 202 into the first pipe fitting 205 and the second pipe fitting 206, and assembling convenience and disassembling convenience of the connecting beam 202 are high. In the above example, the buckle 304 can keep the clamping connection with the clamping hole 303 under the elastic action of the buckle; in another embodiment, the elastic locking structure may further include an elastic member 316, and the buckle 304 may not have elasticity, and the buckle 304 maintains the engagement with the engagement hole 303 under the elastic force of the elastic member 316. Both of these ways also keep the first connection portion 307 and the second connection portion 310 connected by the elasticity of one of the components included in the elastic locking structure. Specific structures of the resilient locking structure will be exemplified below.

In some embodiments, the elastic locking structure further includes a switch structure 301, where the switch structure 301 is connected to the connection beam 202, and the switch structure 301 is used to release the clamped state of the elastic locking structure or to control the elastic locking structure to switch between the clamped state and the disengaged state. When the elastic locking structure is in the locking state, the buckle 304 and the locking hole 303 are mutually locked (specifically, the locking part of the buckle 304 is arranged in the locking hole 303); when the elastic locking structure is in the disengaged state, the buckle 304 is withdrawn out of the clamping hole 303 (specifically, the clamping part of the buckle 304 is located out of the clamping hole 303). The advantage of the switch structure 301 is that the user can lock the first connection portion 307 and the second connection portion 310 to each other or unlock the first connection portion 307 and the second connection portion 310 even if the user does not insert his or her hand into the narrow gap of the television bracket to contact the buckle 304 and drive the buckle 304 to move, which is beneficial to improving the convenience of assembling or disassembling the panel assembly 103.

The resilient locking structure and the switch structure 301 are described in detail below.

The shape of the clip 304 is as shown in fig. 6, the clip 304 is made of a metal sheet, and the clip 304 includes a fixed portion 404, a movable portion 402, and an elastic portion 403 in addition to the clip portion 401. The fixed portion 404 is fixedly connected with the first connecting portion 307, the movable portion 402 and the fixed portion 404 are arranged at intervals along the radial direction of the first pipe fitting 205, the clamping portion 401 is connected to one side of the movable portion 402 opposite to the fixed portion 404, the elastic portion 403 has elasticity, and two ends of the elastic portion 403 are respectively connected with the fixed portion 404 and the movable portion 402. In fig. 6, the elastic portion 403 is curved so as to have elasticity, and in other embodiments, the elastic portion 403 may be provided in other shapes, as long as the elastic portion 403 can have elasticity.

The switch structure includes an operating member 204 and an unlocking block 317, at least a portion of the operating member 204 is exposed outside the connecting beam 202, and the operating member 204 is configured to drive the unlocking block 317 to move relative to the connecting beam 202. The operation element 204 can be touched by a user and operated by the user for pressing, pulling, or the like. How the operation member 204 is interlocked with the unlocking piece 317 will be described later. The unlocking piece 317 is configured to abut against at least one of the movable portion 402 and the elastic portion 403. The operation member 204 can drive the unlocking block 317 to move, referring to fig. 6, when the unlocking block 317 moves in a direction close to the clamping portion 401 (moves rightward), after the unlocking block 317 abuts against the buckle 304, the unlocking block 317 gradually drives the movable portion 402 to move in a direction close to the fixed portion 404, the clamping portion 401 moves along with the movable portion 402, and the clamping portion 401 withdraws from the clamping hole 303. After the unlocking block 317 and the movable portion 402 are separated from each other, the elastic force of the elastic portion 403 drives the movable portion 402 to reset, the movable portion 402 moves in a direction away from the fixed portion 404, and the clamping portion 401 is clamped into the clamping hole 303. The elastic force of the elastic portion 403 is used to drive the movable portion 402 and the fixed portion 404 away from each other, and the elastic force of the elastic portion 403 is used to hold the engaging portion 401 in the engaging hole 303. In this way, the position of the clamping portion 401 can be switched by the movement of the operating member 204, so that the locking and unlocking between the first connection portion 307 and the second connection portion 310 can be achieved.

The provision of the exposed operating member 204 is relatively advantageous in that the user does not need to directly press the clamping portion 401 to switch the position of the clamping portion 401. Since the user does not need to directly press the clamping portion 401, the user does not need to insert his or her hand between the panel assembly 103 and the connection arm assembly 102 or the wall plate assembly 101, and the user is less hindered in releasing the clamping between the first pipe fitting 205 and the second pipe fitting 206, and the convenience in the operation of disassembling the connection beam 202 and the fixing plate 201 is high. If the switch structure 301 is not provided, the total number of parts of the panel assembly 103 is reduced, and the cost of the panel assembly 103 is reduced.

One of the switch structures 301 suitable for use with the catch 304 shown in fig. 6 is described.

Referring to fig. 4, the switch structure 301 includes a sleeve 302. Fig. 10 shows the switch structure 301 of fig. 4 with the sleeve 302 omitted, and as shown in fig. 10, the switch structure 301 further includes a rotating shaft 319 and an elastic member 316. The sleeve 302 is fixed inside the first pipe member 205, and the sleeve 302 and the first pipe member 205 may be connected by screws. As shown in fig. 11, the sleeve 302 includes a plurality of guide grooves 327 and a plurality of fixing notches 328, and the guide grooves 327 and the fixing notches 328 are alternately arranged along the circumferential direction of the sleeve 302.

A portion of the operating member 204 is disposed inside the sleeve 302 and is movable in the axial direction of the sleeve 302. Referring to fig. 10, the operating member 204 includes a guide protrusion 325, and the guide protrusion 325 is disposed in a guide groove 327 and is capable of sliding along the guide groove 327. The operating member 204 further includes a plurality of serrations 326, the serrations 326 being distributed along the circumference of the operating member 204, the serrations 326 being provided with a first chamfer 329 (the first chamfer 329 being shown in fig. 12).

A rotating shaft 319 is provided inside the sleeve 302, the rotating shaft 319 being movable in the axial direction of the sleeve 302 to switch between a first position and a second position. The shaft is rotatable about the central axis of the sleeve 302, the central axis of the sleeve 302 being collinear with the central axis of the shaft 319. Fig. 12 shows the working principle of the switch structure 301, which will be explained in more detail below. In fig. 12 (a), the rotating shaft 319 is in the first position, and accordingly, the elastic locking structure is in the clamped state; the swivel 319 in fig. 12 (d) is in the second position and, correspondingly, the resilient locking structure is in the disengaged state. Referring to fig. 10, the rotating shaft 319 includes a plurality of guide ribs 324 disposed at intervals along a circumferential direction of the rotating shaft 319, the guide ribs 324 extending in an axial direction of the rotating shaft 319, and one end of the guide ribs 324 toward the operating member 204 is provided with a second inclined surface 330 (the second inclined surface 330 is shown in fig. 12). Unlocking block 317 is connected to an end of shaft 319 facing away from operating member 204.

The elastic member 316 includes a first end fixed to the first tube 205 and a second end connected to the unlocking block 317. Taking fig. 10 as an example, the first end is the left end of the elastic member 316, and the second end is the right end of the elastic member 316. It should be noted that, the "relatively fixing the first end to the first pipe 205" may be that the first end is directly fixedly connected to the first pipe 205, or may be that the first end is fixedly connected to a certain intermediate component, and the intermediate component is fixedly connected to the first pipe 205, so as to achieve the relatively fixing between the first end and the first pipe 205. As shown in fig. 10, the switch structure 301 further includes a mounting block 320, where the mounting block 320 is fixedly connected (e.g., by a screw connection) to the first tube 205, and the first end of the elastic member 316 is connected to the mounting block 320. The unlocking block 317 includes a shaft portion 323, a plate portion 322, and an abutment portion 321, and any two of the shaft portion 323, the plate portion 322, and the abutment portion 321 are relatively fixed. One end of the shaft portion 323 is connected to the plate portion 322, the other end of the shaft portion 323 is rotatably inserted into the rotary shaft 319, and the second end of the elastic member 316 is connected to the shaft portion 323. After the switch structure 301 is assembled, the elastic member 316 is always in a compressed state. The plate portion 322 is disposed in a recess of the mounting block 320, and the mounting block 320 is configured to constrain movement of the plate portion 322 from rotation of the unlocking block 317. The abutting portion 321 is connected to an end of the plate portion 322 remote from the shaft portion 323, and the abutting portion 321 is configured to abut against the catch 304.

The operating principle of the switch structure 301 is shown in fig. 12.

Referring to fig. 12 (a), when the rotating shaft 319 is in the first position, the guide rib 324 is disposed in the guide groove 327, and the elastic force of the elastic member 316 maintains the guide rib 324 in the guide groove 327. More specifically, the first inclined surface 329 and the second inclined surface 330 are held in abutment by the elastic force of the elastic member 316, and the guide protrusion 325 is brought into abutment with the right end of the guide groove 327, so that the guide rib 324 is fixed with respect to the sleeve 302 and held in the guide groove 327. Moreover, at this time, the unlocking block 317 is separated from the buckle 304, the clamping portion 401 of the buckle 304 is located in the clamping hole 303, and the elastic locking structure is in a clamping state.

The saw teeth 326 are not provided in the guide groove 327, the portion of the guide rib 324 located outside (the portion farther from the central axis of the rotary shaft 319) is provided in the guide groove 327, the portion of the guide rib 324 located inside (the portion closer to the central axis of the rotary shaft 319) is provided outside the guide groove 327, and the first inclined surface 329 abuts against the portion of the second inclined surface 330 located outside the guide groove 327.

Referring to fig. 12 (a), 12 (b) and 12 (c), as the user presses the operation member 204 (presses the operation member 204 and moves the operation member 204 to the left), the operation member 204 pushes the guide rib 324 to slide along the guide groove 327. Referring to fig. 12 (b) and 12 (c), after the guide rib 324 is separated from the guide groove 327, the second inclined surface 330 moves along the first inclined surface 329 under the elastic force of the elastic member 316, and the rotating shaft 319 rotates around its central axis until the guide rib 324 abuts against the root of the saw tooth 326. Subsequently, as shown in fig. 12 (c) and 12 (d), the user releases the operating member 204, the elastic member 316 drives the rotating shaft 319 and the cam to move rightward, and after the guide rib 324 moves rightward until the second inclined surface 330 abuts against the guide portion, the rotating shaft 319 rotates when moving rightward until the guide rib 324 is caught in the fixing notch 328. As shown in fig. 12 (d), at this time, the rotating shaft 319 is at the second position, the guide rib 324 is withdrawn out of the guide groove 327 and is disposed in the fixing notch 328, the elastic force of the elastic member 316 keeps the guide rib 324 in the fixing notch 328 (the end of the guide rib 324 provided with the second inclined surface 330 abuts against the wall surface of the fixing notch 328), and at this time, the unlocking block 317 abuts against at least one of the movable portion 402 and the elastic portion 403, the clamping portion 401 is located out of the clamping hole, and the elastic locking structure is in a disengaged state.

The operation of switching the click portion 401 to the lock position is similar to the above-described operation. Based on the state shown in fig. 12 (d), the user presses the operating member 204 again and pushes the operating member 204 to move leftwards, the second inclined surface 330 abuts against the first inclined surface 329 again, and the operating member 204 pushes the rotating shaft 319 to move leftwards so that the guide rib 324 is separated from the fixing notch 328. After the guide rib 324 is separated from the fixing notch 328, the second inclined surface 330 moves along the first inclined surface 329 under the elastic force of the elastic member 316, and the rotating shaft 319 rotates until the guide rib 324 abuts against the root of the saw tooth 326. Then, the user releases the operating member 204, the elastic force of the elastic member 316 drives the rotating shaft 319 and the operating member 204 to move rightward, and after the guide rib 324 moves rightward until the second inclined surface 330 thereof abuts against the guide portion, the rotating shaft 319 rotates when moving rightward, until the guide rib 324 enters the guide groove 327. In this way, the rotating shaft 319 is reset to the first position as shown in fig. 12 (a), and accordingly, the unlocking block 317 and the movable portion 402 are separated from each other, and the engaging portion 401 of the buckle 304 is reset to the engaging hole 303.

The advantage of the switch structure 301 is that the user can release the hand by pressing the operating member 204 once, so that the locking portion 401 of the buckle 304 is separated from the locking hole 303, and the locking portion 401 can be kept at the unlocking position without additional force applied by the user; further, the user presses the operating member 204 once again and then releases the hand, so that the engaging portion 401 of the catch 304 is again engaged into the engaging hole 303, and the engaging portion 401 can be maintained in the locking position without an additional force by the user. The switch structure 301 is beneficial to improving the convenience of a user in changing the position of the clamping portion 401 of the buckle 304, thereby improving the convenience of assembling and disassembling the panel assembly 103.

Referring to fig. 6, the unlocking block 317 includes a contact surface 318, the contact surface 318 is a part of an outer surface of the abutment 321, and the contact surface 318 is used for abutting against the movable portion 402. The contact surface 318 is inclined, the contact surface 318 being arranged to: the fixed portion 404 and the movable portion 402 are disposed at intervals along the first direction, and the unlocking block 317 can move along the second direction to approach the buckle 304, so that the clamping portion 401 enters the clamping hole, and along the second direction, the distance between the contact surface 318 and the fixed portion 404 in the first direction gradually increases. The first direction and the second direction are perpendicular to each other, and in fig. 6, the first direction is a front-back direction, and the second direction is a right-to-left direction. The advantage of this arrangement is that during the movement of the unlocking block 317 in the second direction, the unlocking block 317 can push the movable part 402 relatively smoothly towards the fixed part 404, thereby improving the smoothness of the process of switching the clamping part 401 from the locking position to the unlocking position.

In addition to the above-listed switch structure 301, the switch structure 301 may also be configured as a self-locking key switch, and accordingly, a key portion of the self-locking key switch serves as the operation member 204.

Fig. 13 shows a switch structure 301 and a resilient locking structure in another embodiment.

Referring to fig. 13, two buckles 304 are provided, two clamping holes 303 are provided, two buckles 304 are provided at intervals along the first direction, and each buckle 304 is respectively used for being clamped into one clamping hole 303. Each catch 304 is provided with a chute 502 and the catch 304 is movable in a first direction relative to the first tube 205. More specifically, the first pipe 205 is provided with a limit groove 506 inside, and the catch 304 is provided in the limit groove 506 and is movable in the first direction; moreover, the wall surface of the limiting groove 506 can prevent the buckle 304 from moving along the second direction, and the first direction and the second direction are mutually perpendicular.

The elastic locking structure comprises a cross bar 501, an operating member 204 and an elastic member 316, wherein the operating member 204 can penetrate out of the limiting groove 506. The two ends of the cross bar 501 are slidably disposed in two slide grooves 502, respectively. The two ends of the operating member 204 in the second direction are a connection end and an exposed end, wherein in fig. 13, the connection end is the left end of the operating member 204, and the exposed end is the right end of the operating member 204. The connection ends are connected to the cross bar 501 and the exposed ends are provided outside the connection beam 202. Also, the distance between the two slide grooves 502 gradually decreases in the direction from the exposed end to the connection end (i.e., the right-to-left direction in fig. 13). The two ends of the elastic member 316 are respectively connected to the two buckles 304, and the elastic force of the elastic member 316 is used to drive the two buckles 304 away from each other.

In fig. 13, a click portion 401 is provided in the click hole 303. With the clip portion 401 disposed in the clip hole 303, the user can pull the operation member 204 (pull the operation member 204 to move rightward), thereby pulling the cross bar 501. When the cross bar 501 is pulled, since the buckle 304 cannot move in the second direction, both ends of the cross bar 501 slide along the sliding groove 502. With reference to fig. 13 and 14, due to the inclined arrangement of the chute 502, the distance between the two buckles 304 gradually decreases after the cross bar 501 moves rightward, and the buckles 304 also gradually separate from the clamping holes 303. In fig. 14, the elastic member 316 is in a compressed state.

On the contrary, based on the state shown in fig. 14, the user directly releases the operating member 204, and the elastic force of the elastic member 316 drives the buckles 304 away from each other, so that the buckles 304 are snapped into their corresponding snap holes 303. During the process of the clip 304 being snapped into the clip hole 303, the cross bar 501 slides along the chute 502 along with the movement of the clip 304, the operating member slides along with the cross bar 501, and the cross bar 501 and the operating member gradually return to the position shown in fig. 13.

The switch structure 301 shown in fig. 13 can also change the position of the engagement portion 401 by the movement of the operation member 204, thereby fixing the first tube 205 and the second tube 206 to each other or releasing the mutual fixation between the first tube 205 and the second tube 206.

It should be noted that, in other embodiments, the inclination direction of the chute 502 may be set as follows: the distance between the two runners 502 increases gradually in the direction from the exposed end to the connection end (which may correspond to the direction from right to left in fig. 13). This also allows the catch 304 to be snapped into the catch hole 303 and the catch 304 to be withdrawn from the catch hole 303, but in this case the direction of movement of the operating member 204 is opposite to the direction of movement of the operating member 204 in the embodiment shown in fig. 13 and 14 during the process of snapping the catch 304 into the catch hole 303.

If the end surface of the first tube 205 remote from the end of the second tube 206 is referred to as a distal surface, a portion of the operating member 204 may pass out of the distal surface to the outside of the first tube 205. Taking fig. 2 as an example, the distal end surface is the right end surface of the first tube member 205. This arrangement has the advantage of allowing the exposed portion of the operating member 204 to be located at the edge region of the panel assembly 103 for easy access to the operating member 204 by a user. Moreover, since the operating member 204 is threaded out from the distal end face, the exposed portion of the operating member 204 is further away from the mounting plate 201 and the connecting arm assembly 102, and is less susceptible to blocking by the mounting plate 201 and the connecting arm assembly 102 when a user contacts the operating member 204.

Referring to fig. 2, the connection beams 202 are provided in two, the connection beams 202 are horizontally disposed and the two connection beams 202 are spaced apart in the vertical direction. This arrangement may enhance the connection between the hanger arm 104 of the television stand 100 and the panel assembly 103. Specifically, in the case where two connection beams 202 are provided, a part of the hanging arm 104 may be hung on the upper one of the connection beams 202, and another part of the hanging arm 104 may be hung on the lower one of the connection beams 202, so that the hanging arm 104 can be more firmly mounted on the panel assembly 103. In addition, the panel assembly 103 further includes a first connection post 203 and a second connection post, both ends of the first connection post 203 are connected with the two first pipe fittings 205, respectively, and the first connection post 203 is connected with one end of the first pipe fitting 205 away from the second pipe fitting 206, and the second connection post is connected with the two second pipe fittings 206, respectively. The first pipe 205 and the first connecting column 203 can be connected by a screw, and the second pipe 206 and the second connecting column can be connected by a screw. Providing the first and second connection posts 203 and 203 may improve the structural strength and structural stability of the panel assembly 103. In the case where the first connection post 203 is provided, the operation piece 204 is penetrated out from the distal end face and is penetrated out from the end of the first connection post 203 so that the user contacts the operation piece 204.

The connection beam 202 further includes a first protrusion 315, and the first protrusion 315 is disposed at a side of the first limiting portion 306 facing the fixing plate 201 or a side of the second limiting portion 311 facing the fixing plate 201. In the case where the second connection portion 310 is sleeved outside the first connection portion 307, as shown in fig. 7, the first protrusion 315 is provided at a side of the second stopper 311 toward the fixing plate 201 (right side of the second stopper 311), the second protrusion 313 is connected with the second connection portion 310, and the second protrusion 313 protrudes with respect to an outer surface of the second connection portion 310. In other embodiments, if the first connecting portion 307 is sleeved outside the second connecting portion 310, the first protruding portion 315 may also be disposed on a side of the first limiting portion 306 facing the fixing plate 201. The first flange portion 503 and/or the second flange portion 504 are provided with positioning notches 331, and in fig. 15, the first flange portion 503 and the second flange portion 504 are both provided with positioning notches 331, and the positioning notches 331 may be located on the wall of the mounting hole 309. Referring to fig. 16, the first protruding portion 315 is disposed in the positioning notch 331, and the first protruding portion 315 is in snap fit with the positioning notch 331.

The cooperation between the first protruding portion 315 and the positioning notch 331 can play a role in fool-proofing and positioning, and is convenient for a user to assemble the connecting beam 202 and the fixing plate 201. The first protruding portion 315 can improve the overall torsional strength of the connecting beam 202, and the contact area between the connecting beam 202 and the fixing plate 201 can be improved by providing the first protruding portion 315 and the positioning notch 331, so that the bearing capacity of the connecting beam 202 can be improved by providing the first protruding portion 315 and the positioning notch 331. In addition, based on the cooperation of the first protrusion 315 and the positioning notch 331, the connection beam 202 does not rotate relative to the fixing plate 201 about its central axis, so that the rotation of the connection beam 202 does not affect the assembly of the television bracket or affect the connection firmness between the connection beam 202 and the fixing plate 201.

Similarly, referring to fig. 8, the connection beam 202 further includes a second protrusion 313 connected to the first connection part 307 and protruding with respect to an outer surface of the first connection part 307, the inner surface of the second connection part 310 being provided with a positioning groove 314, the second protrusion 313 being disposed in the positioning groove 314. The cooperation between the second protrusion 313 and the positioning groove 314 can realize positioning and fool-proofing between the first connection portion 307 and the second connection portion 310, so that a user can assemble the first pipe fitting 205 and the second pipe fitting 206 conveniently. Based on the cooperation of the second protrusion 313 and the positioning groove 314, the contact area between the first pipe fitting 205 and the second pipe fitting 206 is larger, the overall torsion resistance of the connection beam 202 is also higher, and the bearing capacity of the connection beam 202 is higher. In addition, the engagement of the second protrusion 313 and the detent 314 also prevents the first tube 205 from rotating relative to the second tube 206.

As shown in fig. 7, the first protrusion 315 has a strip shape, and the first protrusion 315 extends in the axial direction of the first pipe 205. In this way, during the process of inserting the second tube 206 and the fixing plate 201, the first protrusion 315 can pass through the positioning notch 331 more smoothly, and the first protrusion 315 and the positioning notch 331 can guide the movement of the second tube 206. Similarly, as shown in fig. 8, the second protrusion 313 has a bar shape, and the second protrusion 313 extends in the axial direction of the first pipe 205. In this way, during the process of inserting the second pipe 206 and the first pipe 205, the second protrusion 313 can slide in the positioning groove 314 relatively smoothly, and the second protrusion 313 and the positioning groove 314 can guide the movement of the first pipe 205 relative to the second pipe 206.

As described above, the positioning groove 314 is provided on the inner surface of the second pipe member 206, and as shown in fig. 16, the positioning groove 314 may be provided inside the first protrusion 315. The positioning groove 314 disposed inside the first protrusion 315 is advantageous to reduce the structural and shape complexity of the second pipe 206, thereby advantageously reducing the processing cost of the second pipe 206, compared to the positioning groove 314 disposed inside the second connection portion 310.

As shown in fig. 1, the present invention also provides a television stand 100, wherein the television stand 100 includes a wall panel assembly 101, a connecting arm assembly 102, a hanging arm 104, and a panel assembly 103 according to any of the above embodiments. Referring to fig. 1, the connecting arm assembly 102 includes a front arm section 105 and a rear arm section 106, the front end of the front arm section 105 is rotatably connected to the fixing plate 201, the rear end of the front arm section 105 is rotatably connected to the front end of the rear arm section 106, and the rear end of the rear arm section 106 is rotatably connected to the wall plate assembly 101. The user can adjust the distance between the panel assembly 103 and the wall panel assembly 101 by changing the angle between the front arm section 105 and the rear arm section 106, thereby adjusting the distance between the television mounted to the panel assembly 103 and the mounting surface on which the wall panel assembly 101 is located. As shown in fig. 8, the first pipe 205 further includes a first supporting portion, and the first supporting portion and the first connecting portion 307 are respectively located on different sides of the first limiting portion 306. As shown in fig. 7, the second pipe 206 further includes a second supporting portion, and the second supporting portion and the second connecting portion 310 are respectively located on different sides of the second limiting portion 311. The hanging arms 104 are provided in two, one hanging arm 104 being mounted on the first support portion and the other hanging arm 104 being mounted on the second support portion.

The television bracket 100 can be split into a plurality of parts for storage and packaging, and the television bracket 100 has high transportation and storage convenience. In addition, since the assembling and disassembling convenience of the panel assembly 103 is high, the assembling and disassembling convenience of the television bracket 100 is high.
