Description

Technical Field

[0001] This application relates to the technical field of display carriers, and specifically relates to a display bracket. Background Art

[0002] A display bracket, also known as a TV bracket, is a bracket specifically configured for hanging flat-panel TVs and flat-panel monitors on supports such as walls and screens. It is applicable to places such as the living room, bedroom, office, conference hall, exhibition hall, hotel, airport, railway station, hospital, bus station, shopping plaza, etc.

[0003] The display bracket of the related technology generally includes a fixing plate connected to the support and a hanging plate connected to the back of the display, and a connection structure is provided between the hanging plate and the fixing plate. During installation, first connect the fixing plate to the support. The fixing plate is provided with a hanging portion extending along the length direction of the fixing plate, and a plurality of connection holes are provided at the bottom of the fixing plate; the hanging plate is pre-installed on the back of the display. The upper end of the hanging plate is provided with a hook for hanging on the hanging portion, and the lower end of the hanging plate is connected with a locking screw or an elastic retaining pin; first hang the hook at the upper end of the hanging plate on the hanging portion of the fixing plate, and then make the locking screw or the elastic retaining pin detachably connected to the bottom of the fixing plate. For example, the display bracket disclosed in the Chinese patent application with the publication number CN206469018U applied by the applicant of this case. The thickness or volume of this display bracket is generally set to be small, so that the distance between the display and the wall is relatively close, which can save indoor space and ensure the aesthetic degree of the combination between the display and the wall, but the tilt angle of this display bracket cannot be adjusted, and a better viewing experience cannot be obtained.

[0004] Another example is the wall-mounted TV bracket disclosed in the Chinese patent application with the publication number CN220770769U applied by the applicant of this case. The tilt angle of the display can be adjusted to meet the better viewing experience of users. Specifically, a folding arm is provided between the fixing plate and the display connecting plate, and the display connecting plate is rotatably connected to the folding arm through a rotating shaft. An arc-shaped hole centered on the rotating shaft is provided on the display connecting plate, and a locking knob passing through the arc-shaped hole is threadedly connected to the folding arm. The display connecting plate together with the display can rotate around the rotating shaft to adjust the tilt angle of the display, and is locked by the locking knob.

[0005] The monitor stand of the above related technology has the following defects in actual use: First, when adjusting the tilt angle of the monitor stand of the related technology, it is very laborious, especially for large-sized monitors, which are relatively heavy in themselves. When adjusting the tilt angle, it is particularly laborious and it is difficult to adjust to the appropriate tilt angle at one time. Moreover, the load-bearing capacity of the monitor stand of the related technology is generally poor. Especially when adjusting the tilt angle of the monitor, the center of gravity of the monitor will also change greatly, resulting in poor connection stability of the monitor. The thickness and volume of the monitor stand are small, which inevitably affects the tilt angle adjustment range of the monitor. Especially for large-sized monitors, the bottom edge often touches the wall when tilting downward. In addition, after the mounting plate on the back of the monitor is hung on the fixing plate on the wall, the space on the back of the monitor is very narrow, and it is very difficult to connect the wiring of the monitor to the socket on the wall behind the monitor. Therefore, before the mounting plate is hung on the fixing plate, it is necessary to first connect the wiring of the monitor to the socket, and then hang the mounting plate on the fixing plate. However, when the mounting plate is hung, the connected wiring may interfere with the socket or other plugs inserted into it. Summary of the Invention

[0006] The technical problem to be solved by this application is to overcome the defects of the above related technologies and provide a monitor stand that makes it labor-saving and convenient to adjust the tilt angle and distance of the monitor, has a strong load-bearing capacity, can avoid touching the wall when adjusting the tilt angle of a large-sized monitor, and can avoid interference of the monitor wiring with the wall socket.

[0007] The technical solution of this application is to provide a monitor stand with the following structure: It includes a fixing plate connected to the surface of the support and at least one tilt angle adjustment bracket. Each of the tilt angle adjustment brackets includes

[0008] a support frame assembly, which is connected to the fixing plate;

[0009] a connecting plate, which is used to connect to the back of the monitor; and

[0010] Rotating bracket, connecting the support frame assembly and the connecting plate, for adjusting the tilt angle and distance of the connecting plate relative to the support frame assembly, and enabling the connecting plate to stay at any position during its movement. The rotating bracket includes two arms hinged in an X shape: a first arm and a second arm, and the distance from the upper end of the first arm to the hinge axis is greater than the distance from the lower end of the first arm to the hinge axis; the upper end of the first arm is rotatably connected to the support frame assembly, and the lower end of the first arm is rotatably connected to the connecting plate; the upper end of the second arm is slidably connected to the connecting plate, and the lower end of the second arm is slidably connected to the support frame assembly; the rotating bracket is used to make the top of the display on the connecting plate tilt downward away from the surface of the support when adjusting the tilt angle and distance of the connecting plate relative to the support frame assembly.

[0011] In some embodiments, a slideway with a high outer end and a low inner end and a smooth transition in the middle is provided on the connecting plate, and a first slider connected to the upper end of the second arm is slidably connected in the slideway; a long hole extending along the height direction of the support frame assembly is provided on the support frame assembly, and a second slider connected to the lower end of the second arm is slidably connected in the long hole.

[0012] In some embodiments, the slideway is an arc hole or an inclined hole opened on the connecting plate.

[0013] In some embodiments, when the connecting plate moves to the first position, the display is close to the surface of the support and parallel to the surface of the support; when the connecting plate moves to the second position, the display has the maximum tilt angle with the top end away from the surface of the support; when the connecting plate moves from the second position towards the first position and crosses the first position, the distance between the top of the display and the surface of the support is less than the distance between the bottom of the display and the surface of the support.

[0014] In some embodiments, at least one set of positioning members is connected to the support frame assembly. Each set of positioning members includes two relatively arranged positioning plates made of soft elastic material, and elastically clamped between the two positioning plates when the connecting plate moves towards the support frame assembly to the limit position.

[0015] In some embodiments, a hook is provided on the support frame assembly for mating and hanging with the top of the fixing plate, and a clamping member is slidably connected to the support frame assembly. The clamping member is movably clamped at the bottom of the fixing plate; an elastic member is connected between the clamping member and the support frame assembly, and the elastic member makes the clamping member always have a movement tendency to be clamped at the bottom of the fixing plate.

[0016] In some embodiments, a driving member is connected to the clamping member, and the driving member is used to drive the clamping member to disengage from the bottom of the fixing plate.

[0017] In some embodiments, there are two tilt angle adjustment brackets, which are respectively arranged on both sides of the fixed plate.

[0018] In summary, compared with the related art, a monitor bracket of the present application has the following advantages:

[0019] First of all, a rotation bracket is connected between the support frame assembly and the connection plate of the tilt angle adjustment bracket of the monitor bracket. The rotation bracket includes two arms hinged in an X shape: a first arm and a second arm, and the distance from the upper end of the first arm to the hinge axis is greater than the distance from the lower end of the first arm to the hinge axis; the upper end of the first arm is rotatably connected to the support frame assembly, and the lower end of the first arm is rotatably connected to the connection plate; the upper end of the second arm is slidably connected to the connection plate, and the lower end of the second arm is slidably connected to the support frame assembly; therefore, when the tilt angle and distance of the monitor are adjusted, the top of the monitor on the connection plate is tilted downward in a direction away from the surface of the support, and during the entire tilt angle and distance adjustment process, the monitor on the connection plate stays at any position of its movement, without the need to additionally provide a locking mechanism to lock the connection plate after adjusting the angle.

[0020] Secondly, since the distance from the upper end of the first arm of the rotation bracket to the hinge axis is greater than the distance from the lower end of the first arm to the hinge axis, it not only ensures the adjustment of the tilt angle and distance of the monitor on the connection plate, but also increases the rotational force arm of the upper part of the connection plate, making it more labor-saving when rotating the top of the monitor in a direction away from the surface of the support. Even when connecting a large-sized monitor, it is very labor-saving to rotate the top of the monitor, and the operation is convenient.

[0021] Furthermore, the upper end of the second arm of the rotation bracket is slidably connected to the connection plate, and the lower end of the second arm is slidably connected to the support frame assembly. When adjusting the tilt angle and distance of the connection plate relative to the support frame assembly, the center of gravity of the monitor on the connection plate moves horizontally on the same horizontal line or approximately on the same horizontal line. That is, when adjusting the tilt angle and distance of the monitor, the height of the center of gravity of the monitor remains unchanged or the change in height is small, so that the connection stability of the monitor is good. On the contrary, the monitor bracket can provide a large load and has a strong load-bearing capacity; and under the action of the rotation bracket, when the upper end of the monitor moves and tilts in a direction away from the surface of the support, the lower end of the monitor will also adaptively move in a direction away from the surface of the support, so that the distance between the lower end of the monitor and the surface of the support always remains fixed or within a certain safe distance range; therefore, even when connecting a large-sized monitor, such as a 100-inch monitor, when the monitor is tilted to the maximum angle, it will not touch the surface of the support.

[0022] In addition, under the action of the rotating bracket, the inclination angle and distance of the connecting plate relative to the support frame assembly can be adjusted. Therefore, when installing the display, first install the connecting plate on the display and connect the wiring of the display to the socket on the surface of the support. Then, hang the support frame assembly of the inclination angle adjustment bracket on the fixing plate. If the wiring of the display interferes with the socket on the surface of the support, the lower end of the display can be rotated away from the surface of the support to slightly move the lower end of the display away from the surface of the support, thereby avoiding interference of the display wiring with the socket on the surface of the support.

[0036] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] See Figure 1 and Figure 2As shown in the figure; an embodiment of the present application discloses a monitor bracket, which is installed on the surface of a support such as a wall, a fence or a screen, and is used for installing a monitor. The monitor bracket includes a fixing plate 1 connected to the surface of the support and at least one tilt angle adjustment bracket 2. The fixing plate 1 has a first surface close to the surface of the support and parallel to the surface of the support, and a second surface facing away from the surface of the support. The second surface is also a vertical plane parallel to the surface of the support. The top edge 100 and the bottom edge 101 of the fixing plate 1 are both formed by bending a metal plate, and there is a certain gap between them and the surface of the support, which is convenient for the installation of the tilt angle adjustment bracket 2.

[0038] In this embodiment, there are two tilt angle adjustment brackets 2, which are respectively arranged on both sides of the fixing plate 1. Each tilt angle adjustment bracket 2 includes a support frame assembly 200, a connecting plate 201 and a rotating bracket. The support frame assembly 200 is used for hanging on the fixing plate 1. The connecting plate 201 is provided with a connecting hole 209, and the connecting hole 209 is adapted to the mounting hole on the back of the monitor. The connecting plate 201 can be installed on the back of the monitor by using a connecting screw; the rotating bracket connects the support frame assembly 200 and the connecting plate 201, and is used to adjust the tilt angle and distance of the connecting plate 201 relative to the support frame assembly 200.

[0039] Specifically, in this embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the rotating bracket includes two arms hinged in an X shape: a first arm 202 and a second arm 203, and the distance from the upper end of the first arm 202 to the hinge axis 208 is greater than the distance from the lower end of the first arm 202 to the hinge axis 208; the upper end of the first arm 202 is rotatably connected to the support frame assembly 200, and the lower end of the first arm 202 is rotatably connected to the connecting plate 201; the upper end of the second arm 203 is slidably connected to the connecting plate 201, and the lower end of the second arm 203 is slidably connected to the support frame assembly 200. The rotating bracket is used to make the top of the monitor on the connecting plate 201 tilt downward in a direction away from the surface of the support when adjusting the tilt angle and distance of the connecting plate 201 relative to the support frame assembly 200.

[0040] Further, rotate the support bracket so that the display on the connecting plate 201 can be adjusted in angle between a first position and a second position. The first position is the vertical position of the display, or the vertical position or the folded position of the connecting plate 201. At this time, the rotating support bracket is in a folded state, and the display is close to the surface of the support and parallel to the surface of the support. The second position is the maximum tilting angle position of the display, that is, the position of the maximum distance from the top of the display to the surface of the support. At this time, the rotating support bracket is in an unfolded state, and the display on the connecting plate 201 is at the limit angle of tilting downward. The rotating support bracket is used to adjust the pitch and tilt angle of the display to meet the viewing experience of users at different angles.

[0041] It is not difficult to understand that when the top of the display rotates away from the surface of the support to make the display in an inclined state, the user holds the top of the display with the hand and applies an outward pulling force. If the turning force arm at the top of the rotating support bracket is small, it is necessary to use a greater force when rotating the display. Especially for large-size displays with a relatively heavy self-weight, it is even more difficult to rotate and adjust the tilt angle. In this embodiment, referring to Figure 3 As shown, since the distance from the upper end of the first arm 202 of the rotating support bracket to the hinge axis 208 is greater than the distance from the lower end of the first arm 202 to the hinge axis 208, it not only ensures the adjustment of the tilt angle of the display on the connecting plate 201, but also increases the turning force arm of the upper part of the connecting plate 201. When rotating the top of the display away from the surface of the support, it is more labor-saving. Even when connecting a large-size display, it is very labor-saving to rotate the top of the display, and the operation is convenient.

[0042] Further, when the display support makes the top of the display rotate away from the surface of the support, it is very labor-saving. To prevent accidental rotation of the top of the display, the display support also allows the connecting plate 201 to move from the second position to the first position direction and cross the first position. At this time, the distance between the top of the display and the surface of the support is less than the distance between the bottom of the display and the surface of the support. Thus, accidental rotation and opening of the top of the display are avoided.

[0043] It is not difficult to understand that when the top of the display moves away from the surface of the support to adjust the tilt angle of the display, the center of gravity of the display will inevitably move downward accordingly, thereby changing the force on the display support and affecting the connection stability of the display. Moreover, during the process of adjusting the tilt angle, the bottom of the display will move toward the surface of the support and may abut against the surface of the support. In this embodiment, to solve the problem of the deviation of the center of gravity of the display, improve the load-bearing capacity of the support, and avoid the bottom of the display from abutting against the surface of the support; refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the upper end of the second arm 203 is slidably connected to the connecting plate 201, and the lower end of the second arm 203 is slidably connected to the support frame assembly 200. When adjusting the tilt angle and distance of the display, the top of the display moves and tilts away from the surface of the support. At this time, the first arm 202 and the second arm 203 rotate and unfold, and both ends of the second arm 203 slide on the connecting plate 201 and the support frame assembly 200 respectively to adjust the center of gravity of the display in real time and adaptively adjust the distance between the bottom of the display on the connecting plate 201 and the wall, so that the center of gravity of the display is at the same horizontal height or approximately the same horizontal height during the entire tilt angle adjustment process. This makes the connection stability of the display good. Conversely, this display bracket can provide a large load and has a strong load-bearing capacity. At the same time, the distance between the lower end of the display and the surface of the support is always kept fixed or within a certain safe distance range to prevent the bottom of the display from touching the surface of the support.

[0044] Exemplarily, as Figure 6 , Figure 7 and Figure 8 shown, where Figure 6 shows the display 4 in a vertical position parallel to the surface of the support, that is, the first position; Figure 7 shows the upper end of the display 4 rotating 6 degrees away from the surface of the support, so that the display 4 is in an inclined intermediate position; Figure 8 shows the upper end of the display 4 rotating 12 degrees away from the surface of the support, so that the display 4 is in the second position with the maximum tilt angle. At the same time, in Figure 6 , Figure 7 and Figure 8 , the center of gravity O of the display and the movement trajectory of the center of gravity O of the display 4 during the entire tilt angle adjustment process are shown, that is, the trajectory height shown by the horizontal line A-B. In Figure 6 , the rotating bracket is in a fully folded state, and the display 4 is arranged parallel to the surface of the support. At this time, the distance between the display 4 and the surface of the support is the smallest, and the center of gravity O of the display 4 is located on the horizontal line A-B; similarly, in this state, the support frame assembly 200 can be used to be hung on the fixing plate 1. In Figure 7 , the distance from the upper end of the display 4 to the surface of the support is greater than the distance from the lower end of the display 4 to the surface of the support, the display 4 is in an inclined state, and the center of gravity O of the display 4 is still located on the horizontal line A-B, that is, during the rotation from the state shown in Figure 6 to the state shown in Figure 7 , the downward movement of the center of gravity O of the display 4 is offset by the upward movement of both ends of the second arm 203, so that the center of gravity O of the display 4 remains at the same horizontal height; in Figure 8 , the display 4 is in the maximum inclined state, and the center of gravity O of the display 4 is still located on the horizontal line A-B. During the process fromFigure 7 rotating from the state shown in Figure 8 During the process of rotating to the state shown in Figure 8 , the downward movement of the center of gravity O of the display 4 is once again offset by the upward movement at both ends of the second arm 203, so that the center of gravity O of the display remains at the same horizontal height. That is, within the entire tilt angle and distance adjustment range of the display 4, the center of gravity O always remains at the same horizontal height, so that the force exerted by the display 4 on the support frame assembly 200 and the fixing plate 1 is constant, resulting in good connection stability of the display 4 and strong load-bearing capacity of the display bracket.

[0045] It can be understood that due to the influence of manufacturing precision errors and assembly clearance errors, during the process of adjusting the tilt angle and distance of the display 4, the center of gravity of the display inevitably deviates from the horizontal line A-B, but the deviation amplitude is relatively small, such as between 0 and 10 millimeters. Therefore, in fact, during the process of adjusting the tilt angle and distance of the display, the center of gravity of the display is generally or approximately at the same horizontal height.

[0046] It is not difficult to understand that the adjustment of the tilt angle and distance of the display is carried out by moving the top of the display away from the surface of the support. During the adjustment process, the bottom of the display is slightly away from the surface of the support, but the distance from the bottom of the display to the surface of the support is less than the distance from the top of the display to the surface of the support. Therefore, under the action of this rotating bracket, when the upper end of the display 4 moves and tilts away from the surface of the support, the lower end of the display 4 will also move away from the surface of the support accordingly, so that the distance between the lower end of the display and the surface of the support always remains fixed or within a certain safe distance range.

[0047] Furthermore, in the above example, if the size of the display is a 100-inch display, in Figure 6 the state shown in Figure 6 , the minimum distance between the bottom of the display and the surface of the support is D1, in Figure 7 the state shown in Figure 7 , if the minimum distance between the bottom of the display and the surface of the support is D2, in Figure 8 the state shown in Figure 8 , if the minimum distance between the bottom of the display and the surface of the support is D3, the values of D1, D2, and D3 are the same.

[0048] Similarly, due to the above-mentioned inevitable manufacturing precision errors and assembly clearance errors, within the entire tilt angle adjustment range of the display, the values of the minimum distances D1, D2, and D3 between the bottom of the display and the surface of the support may not be the same, but within a certain safe distance range, such as D1 is 5 centimeters, D2 is 5.5 centimeters, D3 is 4.8 centimeters, etc., so that the distance between the bottom of the display and the surface of the support is kept within the safe distance range of 4 to 6 centimeters. See Figure 7 and Figure 8In the state shown, even when connecting a display with a larger size, during the process of adjusting the tilt angle and distance of the display, especially when the display is tilted to the maximum angle, the bottom of the display will not touch the surface of the support.

[0049] Further, in this embodiment, the rotational cooperation between the first arm 202 and the second arm 203 of the rotating bracket and the connection relationship between the first arm 202 and the second arm 203 and the connecting plate 201 and the support frame assembly 200 enable the tilt angle of the connecting plate 201 relative to the support frame assembly 200 to be adjustable; therefore, when installing the display, first install the connecting plate 201 on the display and connect the wiring of the display to the socket on the surface of the support. Then, hang the support frame assembly 200 of the tilt angle adjustment bracket 2 on the fixing plate 1. If the wiring of the display interferes with the socket on the surface of the support, the lower end of the display can be rotated away from the surface of the support, making the lower end of the display slightly away from the surface of the support, thereby avoiding interference of the display wiring with the socket on the surface of the support.

[0050] Further, in this embodiment, during the entire tilt angle adjustment process of the display, the display on the connecting plate 201 can stay at any position of its movement without additionally setting a locking mechanism to lock the connecting plate 201 after adjusting the angle. The rotating bracket can use the friction force method to enable the display to stay at any position of its movement. For example, at any rotational connection of the rotating bracket, such as on the hinge shaft 208 of the first arm 202 and the second arm 203, on the rotating shafts at both ends of the first arm 202, or at the sliding connection where the second arm 203 slides on the connecting plate 201, friction plates are installed, and the friction force provided by the friction plates is used to make the connecting plate 201 stay after rotation, ensuring that the display can stay at any position of its movement.

[0051] See Figure 3 and Figure 4As shown, in this embodiment, a slideway 204 with a higher outer end and a lower inner end and a smooth transition in the middle is provided on the connecting plate. A first slider 205 connected to the upper end of the second arm 203 is slidably connected in the slideway 204; a long hole 206 extending along the height direction of the support frame assembly 200 is provided on the support frame assembly 200, and a second slider 207 connected to the lower end of the second arm 203 is slidably connected in the long hole 206. When the display is in the first position, the rotating bracket is in a folded state. The first slider 205 at the first end of the second arm 203 is located at one end or side of the slideway 204 away from the fixing plate 1, while the second slider 207 at the second end of the second arm 203 is located at the lower end or lower side of the long hole 206. When the top of the display moves and tilts away from the surface of the support, the first slider 205 at the first end of the second arm 203 slides along the slideway 204 towards one end or side of the slideway 204 close to the fixing plate 1, and the second slider 207 at the second end of the second arm 203 slides upwards in the long hole 206 towards the upper end or upper side of the long hole 206; that is, during the process of the display rotating and tilting from the first position to the second position, the support height of the second arm 203 is increased to offset the height of the center of gravity of the display when it tilts.

[0052] Further in this embodiment, the length dimensions of the slideway 204 and the long hole 206 can be set according to the tilt angle adjustment range of the display. The first slider 205 and the second slider 207 are respectively pins connected to both ends of the second arm 203.

[0053] Specifically in this embodiment, refer to Figure 3 As shown, the slideway 204 is an arc-shaped hole opened on the connecting plate 201. The horizontal height of one end of the arc-shaped hole close to the support frame assembly 200 is lower than the horizontal height of the end of the arc-shaped hole away from the support frame assembly 200. Therefore, the inner end of the arc-shaped hole is lower and the outer end is higher.

[0054] In other embodiments, the arc-shaped hole 204 on the connecting plate 201 can also be an inclined hole, and the horizontal height of one end of the inclined hole close to the support frame assembly 200 is lower than the horizontal height of the end of the inclined hole away from the support frame assembly 200.

[0055] In some embodiments, in order to prevent the display 4 from being accidentally forced to open when it is in the first position or the vertical position parallel to the surface of the support, the connecting plate 201 is more stably combined with the support frame assembly 200 when the rotating bracket is in a folded state. As Figure 4 and Figure 5 shown, at least one set of positioning members is connected to the support frame assembly 200. Each set of positioning members includes two relatively arranged positioning plates 212 made of soft elastic materials, and is elastically clamped between the two positioning plates 212 when the connecting plate 201 moves towards the support frame assembly 200 to the limit position.

[0056] Exemplarily, as Figure 5 and Figure 6 shown, the support frame assembly 200 is a U-shaped structure formed by bending a metal plate, and the opening faces the connecting plate 201. When the rotating bracket is folded to the first position of the display, the connecting plate 201 is at least partially received in the support frame assembly 200; mounting grooves are provided on two inner side walls of the support frame assembly 200 on the side close to the connecting plate 201, and a soft positioning plate 212 made of rubber is connected in the mounting grooves. Especially when the connecting plate 201 drives the display to move towards the support frame assembly 200, the connecting plate 201 can be elastically clamped between the two positioning plates 212, so as to position and fix the connecting plate 201. Specifically in this embodiment, there are two groups of positioning members, which are respectively arranged corresponding to the first sliding member 205 and the rotating shafts at the lower ends of the first support arms 202. Both ends of the first sliding member 205 and both ends of the rotating shafts at the lower ends of the first support arms 202 protrude out of the surface of the connecting plate 201. Therefore, the positioning plates 212 of the positioning members can play a good positioning role for both ends of the first sliding member 205 and both ends of the rotating shafts at the lower ends of the first support arms; and this can also prevent hard collision with the support frame assembly 200.

[0057] In some embodiments, the support frame assembly 200 is hung on the fixed plate 1. In order to facilitate the hanging connection of the support frame assembly 200 with the fixed plate 1 and prevent the support frame assembly 200 from accidentally detaching from the fixed plate 1 after the hanging connection, as Figure 1 、 Figure 2 and Figure 5 shown, the support frame assembly 200 is provided with a hook 210 that is hung and matched with the top of the fixed plate 1, and a clamping member 3 is slidably connected to the support frame assembly 200, and the clamping member 3 is movably clamped to the bottom of the fixed plate 1; an elastic member 303 is connected between the clamping member 3 and the support frame assembly 200, and the elastic member 303 makes the clamping member 3 always have a tendency to be clamped to the bottom of the fixed plate 1.

[0058] Exemplarily, as Figure 2 and Figure 5As shown, a notch is provided on the upper end of the support frame assembly 200 and near one side of the fixing plate 1. The top of the notch forms a hook 210 that is hooked to the top edge 100 of the fixing plate 1. A groove 211 that can be snapped onto the bottom edge 101 of the fixing plate 1 is provided on the support frame assembly 200 and near one side of the fixing plate 1. A positioning shaft 302 is connected to the support frame assembly 200. The clamping member 3 is slidably fitted on the support frame assembly 200, and a guiding hole 301 for the positioning shaft 302 to pass through is provided on the clamping member 3. The clamping member 3 has a U-shaped clamping portion, and this clamping portion can be snapped onto the top edge 100 of the fixing plate 1 within the groove 211 to prevent the bottom edge 101 of the fixing plate 1 from disengaging from the groove 211; further, the elastic member 303 is a spiral spring, one end of which is connected to the positioning shaft 302 and the other end is connected to the clamping member 3. Under the action of the elastic force, the clamping portion of the clamping member 3 always has a tendency to move to be clamped with the bottom edge 101 of the fixing plate 1; of course, in order to facilitate the hooking of the support frame assembly 200 and the fixing plate 1, a guiding inclined surface is provided on the outer side wall of the clamping portion of the clamping member 3. When the hook 210 is hooked to the top edge 100 of the fixing plate 1, by pressing the support frame assembly 200 inward, under the action of the guiding inclined surface, the bottom edge 101 of the fixing plate 1 can overcome the elastic force of the elastic member 303 and be quickly snapped into the groove 211. At the same time, the clamping member 3 is reset under the action of the elastic member 303 and is clamped to the bottom edge 101 of the fixing plate 1, and the support frame assembly 200 is locked to the fixing plate 1.

[0059] Further, in order to facilitate the disassembly of the support frame assembly 200 and the fixing plate 1, a driving member 300 is connected to the clamping member 3, and the driving member 300 is used to drive the clamping member 3 to disengage from the bottom of the fixing plate 1. Specifically, as Figure 1 and Figure 5 shown, the driving member 300 is a pull rope or a pull rod. The upper end of the pull rope or the pull rod is connected to the clamping member 3. When the clamping portion of the clamping member 3 is to be disengaged from the bottom edge 101 of the fixing plate 1, by pulling the pull rope or the pull rod downward, the clamping member 3 can be driven to move downward, and the clamping portion of the clamping member 3 can be disengaged from the bottom edge 101 of the fixing plate 1, and the operation is very simple and convenient.
