Description

Technical Field

[0001] The utility model relates to the technical field of display screen brackets, in particular to a rear-mounted constant force spring bracket and a display screen supporting structure. Background Art

[0002] Monitor stands are used to stably mount and support display screens, and common monitor stands on the market have the functions of lifting and rotating adjustment, allowing users to adjust the position of the display screen according to their needs. For stands with lifting and adjusting functions, a constant force spring will be set in the lifting structure to provide elastic force to balance the gravity of the display, so that the display can be lifted and adjusted along the stand and fixed in different positions.

[0003] In the related art, a bracket with a lifting and adjusting function includes a bracket shell, a sliding member slidably arranged in the bracket shell, and a first constant force spring assembly arranged in the sliding member and connected to the bracket shell.

[0031] First, it is explained that the utility model adopts a related technology. In the related technology, a group of first constant force spring components 40 are provided inside the display bracket, including one or more first constant force springs. The first constant force spring component 40 can provide a corresponding first elastic force for fixing the first display screen, thereby realizing the hovering of the first display screen at any position on the bracket (it can be understood that any position refers to the position where the display screen does not abut the supporting surface on the bracket or the position that interferes with other structures). Specifically, the display bracket includes a bracket body 10 and a sliding part 20. The sliding part 20 can achieve directional movement on the bracket body 10 through a guide structure. The first constant force spring component 40 is provided on the sliding part 20 and the first constant force spring can be fixed on the inner wall of the bracket. The sliding part 20 has a connecting structure that exposes the display bracket. The connecting structure is used to connect the display screen. During the sliding of the display screen on the bracket, the first constant force spring is stretched and the elastic force provided is constant, thereby ensuring the hovering of the display screen at any position.

[0032] See also Figures 1 to 7 The rear-mounted constant force spring bracket proposed in the utility model includes a bracket body 10, a sliding part 20 and a second constant force spring mechanism 30. The bracket body 10 also includes a notch groove 10b connected to the bracket body 10 and a support sheet 101 arranged near the notch groove 10b; the rear-mounted constant force spring bracket also includes a second constant force spring mechanism 30, and the second constant force spring mechanism 30 movably passes through the notch groove 10b to extend into the sliding space 10A; the second constant force spring mechanism 30 includes an installation component and a second constant force spring 33, and the installation component includes a first connecting part 31 and a second connecting part 32, and the first connecting part 31 is detachably connected to the second connecting part 32; the second constant force spring 33 is arranged on the first connecting part 31 and connected to the second connecting part 32, the first connecting part 31 is detachably connected to the sliding part 20, and the second connecting part 32 is connected to the support sheet 101.

[0033] In the technical solution of the utility model, a sliding part 20 is provided in the bracket body 10, and the sliding part 20 can move up and down along the inner wall of the sliding space 10A, and the sliding part 20 is provided with a first constant force spring group for supporting a display screen of a first weight; in order to enable the same bracket to support a display screen of a second weight (the second weight is greater than the first weight), a notch groove 10b is opened in the bracket body 10, and a support sheet 101 close to the notch groove 10b and built into the sliding space 10A is fixedly set, and a second constant force spring mechanism 30 is inserted into the sliding space 10A through the notch groove 10b, and the second constant force spring mechanism 30 includes an installation component and a second constant force spring 33, and the installation component includes a first constant force spring 33 that can be detached from each other. A connecting part 31 and a second connecting part 32, a second constant force spring 33 is arranged on the first connecting part 31 and connected to the second connecting part 32. When it is necessary to support a display screen of a second weight, the second constant force spring mechanism 30 is placed in the sliding space 10A, and then the first connecting part 31 is connected to the sliding part 20, and the second connecting part 32 is connected to the supporting sheet 101. At this time, the rear-mounted constant force spring bracket has the ability to support a display screen of a second weight, and the display screen of the second weight can move up and down along the bracket body 10 and remain fixed in position at any place; when it is necessary to support a display screen of the first weight, the second constant force spring mechanism 30 can be taken out, so that the same bracket can support two display screens of different weights and can be quickly switched, and the operation is simple.

[0034] In this embodiment, the bracket body 10 also includes a notch groove 10b connected to the sliding space 10A and a support plate 101 fixedly arranged near the notch groove 10b. In order to facilitate the installation of the support plate 101, the notch groove 10b is opened on one side close to the end of the main frame body. The support plate 101 is fixedly arranged in the sliding space 10A. It can be understood that the support plate 101 can be provided with a plurality of first screw holes, and the inner wall of the bracket body 10 is provided with a bearing protrusion, and the bearing protrusion is provided with a second screw hole corresponding to the first screw hole. The support plate 101 is placed on the bearing protrusion and is fixed in the sliding space 10A by locking parts such as bolts. Of course, the support plate 101 can also be fixed by limiting structures such as card slots and card blocks, which is not limited here.

[0035] Furthermore, in order to enable the same bracket to support two display screens of different weights, the bracket body 10 can be installed with a second constant force spring mechanism 30, the second constant force spring mechanism 30 includes a mounting assembly and a second constant force spring 33, the mounting assembly includes a first connecting portion 31 and a second connecting portion 32, the first connecting portion 31 and the second connecting portion 32 can be disassembled from each other, the second constant force spring is arranged on the first connecting portion 31 and connected to the second connecting portion 32, specifically, the client can extend the second constant force spring mechanism 30 into the sliding space 10A through the notch groove 10b, after installation, the first connecting portion 31 can be connected to the sliding portion 20, and the second connecting portion 32 is connected to the support sheet 101, because the position of the support sheet 101 is fixed, at this time, the second connecting portion 32 remains fixed to the support sheet 101 without the intervention of external force, and the display screen of the second weight is connected through the sliding portion 20. After the screen is behind the screen, during the downward movement of the sliding part 20, the first connecting part 31 is driven to move downward synchronously, and then the first connecting part 31 and the second connecting part 32 are separated from each other. Because the second constant force spring 33 is arranged in the first connecting part 31 and fixedly connected to the second connecting part 32, during the downward movement of the sliding part 20, the second constant force spring 33 is stretched to achieve that the display screen of the second weight can be kept hovering at any position on the main frame body. It can be understood that after the second constant force spring 33 is fixedly connected to the second connecting part 32, the second constant force spring 33 can be stretched and assembled into the first connecting part 31 at this length. At this time, the second constant force spring mechanism 30 can provide a preset elastic force, that is, when the display screen is located at the end of the bracket body 10, it can still keep a fixed position, and there is no need to move the display screen of the second weight down a certain distance to achieve position hovering.

[0036] In one embodiment of the present invention, Figure 2 and Figure 7 As shown, the support sheet 101 is provided with a limiting hole 101a connected to the sliding space 10A; the second connecting part 32 includes a hanging piece 321 and a pressing piece 322, the hanging piece 321 is screwed to the pressing piece 322, and the pressing piece 322 is connected to the first connecting part 31; the hanging piece 321 is provided with a hanging arm 323, and the hanging arm 323 is plugged into the support sheet 101; the pressing piece 322 is located in the sliding space 10A, and a pressable button 324 is provided on the top of the pressing piece 322, and a part of the structure of the button 324 is located in the limiting hole 101a, and abuts against the hole wall of the limiting hole 101a facing away from the hanging piece 321.

[0037] In this embodiment, the support sheet 101 is provided with a limiting hole 101a connected to the sliding space 10A, and the first screw hole can be arranged around the limiting hole 101a at the corner of the support sheet 101; the second connecting portion 32 includes a hanging piece 321 and a pressing piece 322, the hanging piece 321 is screwed to the pressing piece 322 to achieve position locking of the two, the hanging piece 321 is provided with a hanging arm 323, and the hanging arm 323 will form a groove structure. After the second constant force spring mechanism 30 passes through the notch groove 10b and is installed in the sliding space 10A, the hanging arm 323 is connected to the support sheet 101, and the support sheet 101 is clamped by the groove structure to achieve the position limitation of the second constant force spring mechanism 30 in the up and down directions; the pressing piece 322 is provided with a button 324, and the button 324 is connected to the pressing piece 322 by a spring structure, so as to realize the function that the button 324 can be pressed, and the pressing piece 322 is provided with a accommodating groove, and the two ends of the spring structure are respectively connected to the groove wall of the accommodating groove and the button 324. The accommodating groove provides a clearance space for the button 324 so that part of its structure can enter the accommodating groove after the button 324 is pressed. After the second constant force spring mechanism 30 and the bracket body 10 are assembled, the side of the button 324 facing the suspension arm 323 abuts against the hole wall of the limiting hole 101a facing away from the suspension arm 323. At this time, the groove structure of the suspension arm 323 is engaged with the support sheet 101 to realize the position limitation of the second constant force spring mechanism 30 in the left and right directions. Because the first connecting part 31 is connected to the sliding part 20, the second constant force spring mechanism 30 can be locked in the position in the up and down, front and back, and left and right directions (in the spatial coordinates, the up and down, front and back, and left and right directions correspond to the Z axis, X axis, and Y axis, respectively) to prevent the second constant force spring mechanism 30 from loosening.

[0038] In one embodiment of the present invention, Figure 7 As shown, a side of the button 324 facing away from the pressing member 322 forms a guide surface 324 a , and the guide surface 324 a can abut against a side of the supporting sheet 101 facing the pressing member 322 .

[0039] In this embodiment, a guide surface 324a is formed on the side of the button 324 facing away from the pressing piece 322. During the assembly of the second constant force spring mechanism 30 and the bracket body 10, the guide surface 324a can abut against the side of the support sheet 101 facing the pressing piece 322, so that when the second constant force spring mechanism 30 moves toward the sliding part 20, the support sheet 101 presses the guide surface 324a to make it enter the accommodating groove of the pressing piece 322. After the second constant force spring mechanism 30 is installed in place, the button 324 rebounds into the limiting hole 101a to realize the locking function.

[0040] In one embodiment of the present invention, Figure 7 As shown, the hanging member 321 is provided with two locking arms 325 , and the two locking arms 325 are arranged opposite to each other and are respectively screwed to one side of the pressing member 322 .

[0041] In this embodiment, the suspension member 321 is provided with two locking arms 325, each locking arm 325 is provided with a first preset screw hole, and the opposite sides of the pressing member 322 are respectively provided with second first preset screw holes, and each first preset screw hole corresponds to a first preset screw hole. The two locking arms 325 are respectively screwed to one side of the pressing member 322, and the pressing member 322 can be locked to the suspension member 321 by bolts; further, each locking arm 325 is provided with a slot structure on the side facing the pressing member 322, and a block structure is protruding from the side of the pressing member 322. In the process of assembling the suspension member 321 and the pressing member 322, the slot structure and the block structure are first plugged in to achieve the function of preliminary locking and positioning the screw hole, and then the bolt structure is used to complete the secondary locking to prevent the suspension member 321 and the pressing member 322 from loosening, thereby causing position deviation, resulting in difficulty in assembling the second constant force spring mechanism 30 and the bracket body 10.

[0042] In one embodiment of the present invention, Figure 7 As shown, a first plug connector 326 is protruding from one end of the pressing member 322 away from the button 324 , and a first slot 31B adapted to the first plug connector 326 is provided on the first connecting portion 31 , and the first plug connector 326 is plugged into the first slot 31B.

[0043] In this embodiment, a first plug connector 326 is protruding from one end of the pressing member 322 away from the button 324, and the first connecting portion 31 is provided with a first slot 31B adapted to the first plug connector 326. The first plug connector 326 is plugged into the first slot 31B, thereby reducing the difficulty of assembling the pressing member 322 and the first connecting portion 31, and making the pressing member 322 and the first connecting portion 31 only have a relatively fixed connection relationship without locking the two, thereby realizing a separable and fixed matching relationship between the pressing member 322 and the first connecting portion 31.

[0044] In one embodiment of the present invention, Figure 7 As shown, the first plug connector 326 is provided with a first guiding inclined surface 326a, a groove wall of the first insertion slot 31B forms a second guiding inclined surface 31a adapted to the first guiding inclined surface 326a, and the first guiding inclined surface 326a abuts against the second guiding inclined surface 31a.

[0045] In this embodiment, a first guide bevel 326a is provided on the side of the first plug connector 326 facing the hanging member 321, so that the cross-section of the first plug connector 326 gradually decreases from the end connected to the pressing member 322 to the end away from the pressing member 322, and the groove wall of the first slot 31B facing away from the hanging member 321 forms a second guide bevel 31a adapted to the first guide bevel 326a, so that the cross-section of the first slot 31B gradually increases from the end away from the pressing member 322 to the end close to the pressing member 322, so that the first plug connector 326 is convenient to insert into the first slot 31B, so that the first guide bevel 326a abuts against the second guide bevel 31a, and the assembly relationship of the two guide bevels abutting each other can play a guiding role when disassembling the first connecting part 31 and the pressing member 322, and the setting of the guide bevel increases the contact area between the two, further improving the connection stability between the first connecting part 31 and the pressing member 322.

[0046] In one embodiment of the present invention, Figure 4 and Figure 7 As shown, a second plug connector 313 is protrudingly provided on one side of the first connection portion 31 facing away from the second connection portion 32 along the moving direction, and the sliding portion 20 is provided with a second slot 20A adapted to the second plug connector 313, and the second plug connector 313 is plugged into the second slot 20A.

In this way, when assembling the second constant force spring mechanism 30 and the sliding part 20, the second plug connector 313 can be directly inserted into the second slot 20A for easy assembly.

[0048] In one embodiment of the present invention, Figure 7 As shown, a limiting groove 31A is provided on one side of the first connecting portion 31 facing the second connecting portion 32 along the moving direction, and the second constant force spring 33 is disposed in the limiting groove 31A.

[0049] In this embodiment, a limiting groove 31A is provided on one side of the first connecting portion 31 facing the second connecting portion 32 along the moving direction, and the second constant force spring 33 is arranged in the limiting groove 31A. In this way, the position of the second spring can be locked to prevent the second spring from loosening during the movement of the display screen, causing curling and jamming.

[0050] In one embodiment of the present invention, Figure 4 and Figure 7 As shown, the first connection portion 31 includes a plug connector 311 and two blocking pieces 312 , each blocking piece 312 is disposed on an opposite side of the plug connector 311 and encloses a limiting groove 31A; the plug connector 311 is provided with a second plug connector 313 .

[0051] In this embodiment, the first connecting part 31 includes a plug-in component 311 and two blocking plates 312.
