Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a lifting stand and display device. Background Technology

[0002] Display devices such as monitors, touch screen all-in-one machines, and flat-screen TVs have gradually become larger in size in recent years to present better visual effects and are widely used in various places such as classrooms, exhibition halls, and conference rooms.

[0003] Lifting stands are commonly used to install and support display devices. They allow the display device to be raised, lowered, and moved, significantly improving its ease of use. Currently, lifting stands on the market are mainly divided into dual-column lifting stands and single-column lifting stands. Dual-column lifting stands have higher manufacturing costs, while single-column lifting stands suffer from poor support stability and are prone to swaying and tilting during lifting. Utility Model Content

[0004] The present invention aims to provide a wall-mounted structure and display device to solve the technical problem that single-column lifting legs are prone to shaking and tilting during the lifting process in the prior art.

[0005] The present invention addresses its technical problem by providing the following technical solution: a lifting tripod, comprising:

[0006] Supporting framework;

[0007] A lifting module, comprising a lifting column and a mounting bracket disposed on the lifting column, the mounting bracket being used to mount a display device, the lifting column being drively connected to the mounting bracket to drive the mounting bracket to lift and lower;

[0008] The mounting bracket has a first clamping portion and a second clamping portion disposed opposite to each other, and the support frame is clamped between the first clamping portion and the second clamping portion to restrict the movement of the mounting bracket along the thickness direction of the display device.

[0009] In this embodiment, the supporting frame provides stable support and limitation for the mounting bracket through the limiting cooperation between the supporting frame and the first clamping part and the second clamping part, thereby preventing the mounting bracket from shaking or shifting during the lifting process, preventing the display device on the mounting bracket from shaking or tilting during use, and ensuring the stability of the supporting frame during use.

[0010] In some embodiments, the support frame includes a support column having a first sidewall and a second sidewall disposed opposite to each other;

[0011] The lifting stand further includes a first limiting member and a second limiting member. The first limiting member is connected to the first clamping part and abuts against the first side wall, and the second limiting member is connected to the second clamping part and abuts against the second side wall.

[0012] In this embodiment, by adding an additional first and second limiting component to engage with the support column of the support frame, wear caused by direct contact between the support frame and the first and second clamping parts is avoided during the lifting and lowering of the mounting bracket. Furthermore, the first and second limiting components are consumable parts, facilitating maintenance and replacement, thus extending the service life of the lifting tripod.

[0013] In some embodiments, the support column further includes a third sidewall, which is connected between the first sidewall and the second sidewall;

[0014] The lifting platform further includes a third limiting member, at least one of the first limiting member and the second limiting member is connected to the third limiting member, and the third limiting member abuts against the third side wall.

[0015] In this embodiment, the third limiting member cooperates with the third sidewall to limit the swaying and offset of the mounting bracket along the width direction of the display device. Thus, the first and second limiting members limit the offset of the mounting bracket along the thickness direction of the display device, and the third limiting member limits the swaying and offset of the mounting bracket along the width direction of the display device. This effectively limits the swaying and tilting of the mounting bracket in the horizontal direction, ensuring the stability of the display device during use and lifting.

[0016] In some embodiments, the first limiting member, the second limiting member, and the third limiting member are all elastic limiting members.

[0017] The plastic limiting parts have good smoothness and wear resistance, which can significantly reduce the frictional resistance of the first, second and third limiting parts relative to the first, second and third side walls, prevent the first, second and third limiting parts from interfering with the lifting and lowering of the mounting bracket, reduce frictional noise during the lifting and lowering process of the mounting bracket, and improve the service life of the lifting legs.

[0018] In some embodiments, the third limiting member is integrally formed with the first limiting member or the second limiting member.

[0019] In this embodiment, the integrally formed first and third limiting components, or the integrally formed second and third limiting components, help to reduce production and assembly costs, and improve installation accuracy and structural stability.

[0020] In some embodiments, the first limiting member includes a first limiting plate and a first elastic pad, the first limiting plate being fixedly connected to the first clamping portion, and the first elastic pad being disposed on the side of the first limiting plate facing the first sidewall and abutting against the first sidewall; and / or

[0021] The second limiting member includes a second limiting plate and a second elastic pad. The second limiting plate is fixedly connected to the second clamping part, and the second elastic pad is disposed on the side of the second limiting plate facing the second sidewall and abuts against the second sidewall; and / or

[0022] The third limiting member includes a third limiting plate and a third elastic pad. The third limiting plate is fixedly connected to the first limiting plate or the second limiting plate. The third elastic pad is disposed on the side of the third limiting plate facing the third sidewall and abuts against the third sidewall.

[0023] In this embodiment, the first elastic pad, the second elastic pad, and the third elastic pad have good buffering and shock absorption performance, avoiding wear and noise when the first limiting plate, the second limiting plate, and the third limiting plate directly contact the first side wall, the second side wall, and the third side wall respectively, and reducing the shaking and wobbling when the display device is operated.

[0024] In some embodiments, there are two support columns, and the support frame further includes a crossbeam and a locking member. The two ends of the crossbeam are respectively fixedly connected to the two support columns, and the locking member and the crossbeam are connected to form a limiting hole.

[0025] The lifting column passes through the limiting hole and is limited and engaged with the limiting hole.

[0026] In this embodiment, the lifting column passes through the limiting hole and is locked by the locking member, which restricts the shaking and vibration of the lifting column, which helps to further reduce the shaking and vibration of the mounting bracket and display device during use, and ensures the stability of the display device.

[0027] In some embodiments, the mounting bracket includes a mounting box and mounting frames and limiting strips disposed on opposite sides of the mounting box. The mounting box is connected to the lifting column, the mounting frame has a first clamping portion, and the limiting strip has a second clamping portion.

[0028] In some embodiments, a movable base is also included, to which the support frame is fixedly connected.

[0029] In this embodiment, the movable base can drive the lifting tripod to move, improving ease of use and flexibility, and enabling the lifting tripod to better adapt to various usage scenarios and needs.

[0030] To address its technical problems, this utility model also provides a display device, which includes the lifting bracket described in any of the above embodiments, and...

[0031] The display device is fixedly installed on the mounting bracket.

[0032] Since the display device has the lifting stand in any of the above embodiments, it also has the beneficial effects of the above embodiments. For specific beneficial effects, please refer to the above text, which will not be repeated here. Attached Figure Description

[0042] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0044] Lifting stands are commonly used to install and support display devices. Traditional lifting stands are mainly divided into double-column lifting stands and single-column lifting stands. Among them, double-column lifting stands have higher manufacturing costs, while single-column lifting stands have poor support stability and are prone to shaking and tilting during use.

[0045] To address the technical problem that existing lifting stands cannot balance manufacturing cost and operational stability, this utility model provides a lifting stand, including a support frame and a mounting bracket. The mounting bracket has a first clamping part and a second clamping part for holding the support frame. Through the limiting cooperation between the support frame and the first and second clamping parts, the support frame provides stable support and limitation for the mounting bracket, preventing the display device on the mounting bracket from shaking or tilting during use, and avoiding shaking or displacement of the mounting bracket during lifting, thus ensuring the operational stability of the support frame.

[0046] The following will be combined with the appendix Figures 1 to 6 The lifting stand 100 and display device provided in the embodiments of this utility model will be described in detail.

[0047] Please see Figures 1 to 3 This utility model provides a lifting stand 100, which includes a support frame 10 and a lifting module 20. The lifting module 20 includes a lifting column 21 and a mounting bracket 22 disposed on the lifting column 21. The mounting bracket 22 is used to install a display device. The lifting column 21 is connected to the mounting bracket 22 to drive the mounting bracket 22 to lift. The mounting bracket 22 has a first clamping part 2201 and a second clamping part 2202 disposed opposite to each other. The support frame 10 is clamped between the first clamping part 2201 and the second clamping part 2202 to limit the movement of the mounting bracket 22 along the thickness direction of the display device.

[0048] The display device can be a touch screen all-in-one machine, teaching video equipment, smart blackboard, flat-screen TV, or other smart device. Optionally, the display device can be fixed to the mounting bracket 22 by means of clips, threads, or other methods. When the lifting column 21 is activated, it can drive the mounting bracket 22 and the display device to rise or fall, thereby adjusting the height of the display device.

[0049] The mounting bracket 22 has a first clamping portion 2201 and a second clamping portion 2202 disposed opposite to each other. The first clamping portion 2201 and the second clamping portion 2202 are respectively located on opposite sides of the support frame 10. Through the limiting cooperation between the support frame 10 and the first clamping portion 2201 and the second clamping portion 2202, the support frame 10 provides stable support and limiting for the mounting bracket 22, thereby restricting the mounting bracket 22 along the thickness direction of the display device (i.e., Figure 2 The movement of the support frame 10 in a direction perpendicular to the paper plane prevents the display device on the mounting bracket 22 from shaking or tilting during the lifting process, and also prevents the mounting bracket 22 from shaking or shifting during the lifting process, thus ensuring the stability of the support frame 10.

[0050] It should be understood that the limiting cooperation between the first clamping part 2201 and the second clamping part 2202 and the support frame 10 does not restrict the movement of the first clamping part 2201 and the second clamping part 2202 relative to the support frame 10 in the vertical direction. When the lifting column 21 is activated, the lifting column 21 will drive the mounting bracket 22 to move in the vertical direction. At this time, the first clamping part 2201 and the second clamping part 2202 will move in the vertical direction relative to the support frame 10.

[0051] Optionally, the first clamping part 2201 and the second clamping part 2202 can be in the form of clamping surfaces.

[0052] Please see Figure 4 In some embodiments, the support frame 10 includes a support column 11, the support column 11 having a first sidewall 111 and a second sidewall 112 disposed opposite to each other. The lifting leg 100 also includes a first limiting member 30 and a second limiting member 40. The first limiting member 30 is connected to the first clamping part 2201 and abuts against the first sidewall 111, and the second limiting member 40 is connected to the second clamping part 2202 and abuts against the second sidewall 112.

[0053] like Figure 4 As shown, the support column 11 is arranged vertically, and the support column 11 can be a square column. The first limiting member 30 can be installed in the first clamping part 2201 by means of screws, snap-fit ​​or other detachable means, and the second limiting member 40 can be installed in the second clamping part 2202 by means of screws, snap-fit ​​or other detachable means.

[0054] The first limiting member 30 and the second limiting member 40 can be plate-shaped structures, column-shaped structures, etc. The first limiting member 30 and the second limiting member 40 are parallel to each other. The support column 11 is sandwiched between the first limiting member 30 and the second limiting member 40, so that the first side wall 111 and the second side wall 112 abut against the first limiting member 30 and the second limiting member 40 respectively, ensuring the stability of the display device during use and lifting.

[0055] In this embodiment, by additionally adding a first limiting member 30 and a second limiting member 40 to engage with the support column 11 of the support frame 10, wear caused by direct contact between the support frame 10 and the first clamping part 2201 and the second clamping part 2202 during the lifting and lowering of the mounting bracket 22 is avoided. Furthermore, the first limiting member 30 and the second limiting member 40 are consumable parts, facilitating maintenance and replacement, thus extending the service life of the lifting leg 100.

[0056] In other embodiments, the first limiting member 30 and the second limiting member 40 may also be installed on opposite sides of the support column 11 and abut against the first clamping part 2201 and the second clamping part 2202 respectively.

[0057] Optionally, there are two support columns 11, which are respectively clamped between the corresponding first limiting member 30 and second limiting member 40. The two support columns 11 provide balanced and stable support and limiting for the mounting bracket 22, further improving the stability and safety of the lifting leg 100.

[0058] In some embodiments, the support column 11 further includes a third sidewall 113 connected between the first sidewall 111 and the second sidewall 112. The lifting leg 100 further includes a third limiting member 50, at least one of the first limiting member 30 and the second limiting member 40 is connected to the third limiting member 50, and the third limiting member 50 abuts against the third sidewall 113.

[0059] like Figure 4 As shown, the third limiting member 50 is perpendicularly connected to the second limiting member 40, and the third limiting member 50 and the second limiting member 40 form an approximate "L" shape, facilitating the extension of the third limiting member 50 to and abutting against the third sidewall 113. It is understood that in other embodiments, the third limiting member 50 may also be fixedly connected to the second limiting member 40. Furthermore, there may be two third limiting members 50, one of which is fixedly connected to the first limiting member 30, and the other is fixedly connected to the second limiting member 40.

[0060] The third limiting member 50 engages with the third side wall 113 to restrict the mounting bracket 22 along the width direction of the display device (i.e., Figure 2 The first limiting member 30 and the second limiting member 40 limit the offset of the mounting bracket 22 along the thickness direction of the display device, and the third limiting member 50 limits the swaying and offset of the mounting bracket 22 along the width direction of the display device. This effectively limits the swaying and tilting of the mounting bracket 22 in the horizontal direction and ensures the stability of the display device during use and lifting.

[0061] like Figure 1 As shown, in some embodiments, the support column 11 further includes a fourth side wall 114, which is disposed opposite to the third side wall 113. The support column 11 and the third limiting member 50 are two in number. One of the third limiting members 50 abuts against the third side wall 113 of the corresponding support column 11, restricting the horizontal movement of the mounting bracket 22 to the right. The other third limiting member 50 abuts against the fourth side wall 114 of the corresponding support column 11, restricting the horizontal movement of the mounting bracket 22 to the left, further restricting the swaying and tilting of the mounting bracket 22 in the horizontal direction.

[0062] In some embodiments, the first limiting member 30, the second limiting member 40, and the third limiting member 50 are all elastic limiting members. Optionally, the first limiting member 30, the second limiting member 40, and the third limiting member 50 can all be made of polymer plastics, such as polyethylene (PE), polytetrafluoroethylene (PTFE), etc. These elastic materials have good smoothness and wear resistance, which can significantly reduce the frictional resistance of the first limiting member 30, the second limiting member 40, and the third limiting member 50 relative to the first sidewall 111, the second sidewall 112, and the third sidewall 113, prevent the first limiting member 30, the second limiting member 40, and the third limiting member 50 from interfering with the lifting and lowering of the mounting bracket 22, reduce the frictional noise during the lifting and lowering process of the mounting bracket 22, and improve the service life of the lifting leg 100.

[0063] In some embodiments, the third limiting member 50 is integrally formed with the first limiting member 30 or the second limiting member 40, which helps to reduce production and assembly costs, improve installation accuracy, and enhance structural stability.

[0064] Please refer to 4. Figure 5 and Figure 6 In some embodiments, the first limiting member 30 includes a first limiting plate 31 and a first elastic pad 32. The first limiting plate 31 is fixedly connected to the first clamping part 2201, and the first elastic pad 32 is disposed on the side of the first limiting plate 31 facing the first sidewall 111 and abuts against the first sidewall 111. And / or the second limiting member 40 includes a second limiting plate 41 and a second elastic pad 42. The second limiting plate 41 is fixedly connected to the second clamping part 2202, and the second elastic pad 42 is disposed on the side of the second limiting plate 41 facing the second sidewall 112 and abuts against the second sidewall 112. And / or the third limiting member 50 includes a third limiting plate 51 and a third elastic pad 52. The third limiting plate 51 is fixedly connected to the first limiting plate 31 or the second limiting plate 41, and the third elastic pad 52 is disposed on the side of the third limiting plate 51 facing the third sidewall 113 and abuts against the third sidewall 113.

[0065] The first limiting plate 31, the second limiting plate 41, and the third limiting plate 51 can be made of metal to improve their structural strength. The first limiting plate 31 and the second limiting plate 41 can be installed to the first clamping part 2201 and the second clamping part 2202 by means of screws, snap-fits, etc. The third limiting plate 51 can be fixedly connected to the first limiting plate 31 or the second limiting plate 41 by means of screw connection, welding, or integral molding, for example, in... Figure 6 In the middle, the third limiting plate 51 and the second limiting plate 41 are configured to be integrally formed.

[0066] The first elastic pad 32, the second elastic pad 42 and the third elastic pad 52 can be respectively fixed to the first limiting plate 31, the second limiting plate 41 and the third limiting plate 51 by means of glue bonding. Optionally, the first elastic pad 32, the second elastic pad 42 and the third elastic pad 52 can be made of materials such as foam, sponge, etc. These materials have good buffering and shock-absorbing properties, avoiding abrasion and noise when the first limiting plate 31, the second limiting plate 41 and the third limiting plate 51 are in direct contact with the first side wall 111, the second side wall 112 and the second side wall 112 respectively, and reducing the jitter and晃动 of the display device during operation and use.

[0067] Please refer to Figure 3 , in some embodiments, there are two support columns 11, and the support frame 10 further includes a cross beam 12 and a locking member 13. The two ends of the cross beam 12 are respectively fixedly connected to the two support columns 11. The locking member 13 is connected to the cross beam 12 to jointly enclose a limiting hole 130, and the lifting column 21 is inserted into the limiting hole 130 and is in limiting cooperation with the limiting hole 130.

[0068] The shape and size of the locking member 13 are adapted to those of the lifting column 21. The locking member 13 can be a clamp structure adapted to the lifting column 21, and the lifting column 21 is locked and limited by the clamp.

[0069] As Figure 3 shown, optionally, the locking member 13 can be generally in the shape of a "Ji" character. The two side edges extending outward in the outer shape of the locking member 13 can be fixedly connected to the cross beam 12 by bolts and nuts. The opening of the locking member 13 faces the cross beam 12 and jointly encloses a limiting hole 130 with the cross beam 12.

[0070] The lifting column 21 is inserted into the limiting hole 130 and is tightly locked by the locking member 13, restricting the swaying and jitter of the lifting column 21, which is beneficial to further reducing the swaying and jitter of the mounting bracket 22 and the display device during use and ensuring the use stability of the display device.

[0071] In some embodiments, the cross beam 12 and the locking member 13 are generally located at the top of the outer tube of the lifting column 21, that is, the top of the outer tube is in limiting cooperation with the limiting hole 130. The support frame 10 further includes a bottom beam 14. The bottom end of the lifting column 21 can be fixed to the bottom beam 14 by fasteners such as screws, further improving the support and limiting effect on the lifting column 21 and enhancing the use stability of the lifting column 21 and the mounting bracket 22.

[0072] Please refer to Figure 3 , in some embodiments, the mounting bracket 22 includes a mounting box 221 and mounting frames 222 and limiting strips 223 provided on opposite sides of the mounting box 221. The mounting box 221 is connected to the lifting column 21. The mounting frame 222 has a first clamping portion 2201, and the limiting strip 223 has a second clamping portion 2202.

[0073] Optionally, the lifting column 21 includes a hollow column body and a lead screw nut disposed within the column body, as well as a drive motor fixedly connected to the mounting box 221. The drive motor is connected to the lead screw drive, and the nut is sleeved on the lead screw and fixedly disposed in the column body. Optionally, the housing of the drive motor is fixedly connected to the mounting box 221. When the motor is started, the drive motor drives the lead screw nut to rotate, causing relative movement between the lead screw and the lead screw nut. Thus, the lead screw can push the drive motor and the mounting box 221 to move up and down, thereby realizing the lifting and lowering of the mounting bracket 22 and the display device.

[0074] The mounting bracket 22 includes a mounting box 221, a mounting frame 222, and a limiting strip 223. The mounting frame 222 and the limiting strip 223 are disposed on opposite sides of the mounting box 221 in the thickness direction. The mounting frame 222 is used to mount the display device. The mounting frame 222 and the limiting strip 223 can be fixed to the mounting box 221 by means of threaded connection, snap-fit, etc., or they can be integrally formed with the mounting box 221. Specifically, the mounting frame 222 extends to opposite ends in the length direction of the mounting box 221 to form a first clamping part 2201, and the limiting strip 223 extends to opposite ends in the length direction of the mounting box 221 to form a second clamping part 2202.

[0075] Please see Figure 2 In some embodiments, the lifting tripod 100 also includes a movable base 60, and the support frame 10 is fixedly connected to the movable base 60. For example, the support frame 10 can be fixed to the movable base 60 by fasteners such as screws and bolts. The movable base 60 can drive the lifting tripod 100 to move, improving the ease of use and flexibility, so that the lifting tripod 100 can better adapt to various usage scenarios and needs.

[0076] Optionally, the bottom of the movable support is provided with casters 61 to enable the movement of the lifting leg 100.
