Technical Field

[0001] This utility model relates to the field of display stand technology, specifically to a portable display stand. Background Technology

[0002] With the development of science and technology, whiteboards, blackboards, drawing boards, and monitors have become increasingly important in daily life, study, and work. These boards often need to be displayed at a certain angle or for easy writing.

[0003] Existing board supports generally adopt a fixed or assembled structure. When it is necessary to adjust the placement of the boards, the boards need to be lifted and rotated. When the boards are heavy or large, adjusting their orientation is inconvenient. In addition, the supports take up too much space, are not easy to fold and store, and are especially inconvenient to carry around. Utility Model Content

[0004] This utility model provides a portable plate-type support that can overcome some or all the defects of the prior art.

[0005] According to the present invention, a portable plate-type support includes two support components spaced apart, and a stretching and contracting part is provided between the two support components. The stretching and contracting part is used to drive the two support components to unfold and retract. The support component includes a hinged base and a mating strip. The mating strip forms a mating surface on the side away from the base, and the mating surface is provided with two rolling parts spaced apart along the length direction.

[0006] Preferably, the stretching and shrinking part includes two opposing hinged transverse stretching bars and a mating plate located on the mating bar near the base. The mating plate forms a mating groove along its length, and a mating shaft is formed on the side of the transverse stretching bar near the mating plate. The mating shaft is used for sliding engagement with the mating groove, and a mating hole is formed through the end away from the mating shaft. A mating post is formed on the mating bar, and the mating post is rotatably engaged with the mating hole.

[0007] Preferably, the mating plate is hinged to an inclined support bar on the side away from the mating bar, and the base is formed with at least one snap-fit ​​groove on the side near the mating bar, with the inclined support bar corresponding to the snap-fit ​​groove.

[0008] Preferably, the end of the inclined support bar away from the mating plate forms a mating hook, which is used to abut against the snap-fit ​​groove.

[0009] Preferably, clearance grooves are formed at both of the two transverse tension bars, and the bottom of the clearance grooves slides together when the two transverse tension bars are engaged.

[0010] Preferably, a positioning pin is formed on the side of the mating plate near the base, and a corresponding positioning hole is formed on the base. The positioning pin is used to mate with the positioning hole.

[0011] Preferably, a support hook is formed at the end of the base near the hinge point with the mating strip, and the support hook extends toward the mating strip.

[0012] Preferably, the rolling part is a rolling shaft, which rotates in conjunction with the mating strip.

[0013] Beneficial effects: The stretching and contracting section can drive the two support components to move closer or further apart, thus allowing adjustment according to the size of the board, making it easy to store and unfold. The board is set at the mating strip, and the base and the mating strip are hinged, so the mating strip can rotate relative to the base, making it easy to adjust the angle between the base and the mating strip, thereby adjusting the placement angle of the board.

[0014] Furthermore, a rolling part is provided on the mating surface, which allows the plate to rotate relative to the mating part, so that the plate does not need to be removed from the mating surface for reversal.

[0015] With the above structure, the portable plate holder of this application can be better stored and unfolded, and is easy to carry. Attached Figure Description

[0025] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0026] Example 1

[0027] Seen in Figure 1-2 This embodiment provides a portable board-type bracket, including two support components 100 spaced apart. A stretching and contracting part is provided between the two support components 100. The stretching and contracting part is used to drive the two support components 100 to unfold and retract. Each support component 100 includes a hinged base 210 and a mating strip 220. The mating strip 220 forms a mating surface 221 on the side away from the base 210. The mating surface 221 is provided with two rolling parts spaced apart along its length.

[0028] According to the solution provided in this embodiment, the stretching and contracting part can drive the two support components 100 to move closer or further away, so it can be adjusted according to the size of the plate, thereby facilitating storage and unfolding. The plate is set at the mating strip 220. The base 210 and the mating strip 220 are hinged, so the mating strip 220 can rotate relative to the base 210, thereby facilitating the adjustment of the angle between the base 210 and the mating strip 220, thereby adjusting the placement angle of the plate.

[0029] Furthermore, a rolling part is provided on the mating surface 221, which allows the plate to rotate relative to the mating part, so that the plate does not need to be removed from the mating surface 221 for reversal.

[0030] It is understandable that the rolling part can be a rolling shaft, a rolling ball, etc.

[0031] In other words, when in use, the board can be pressed against the rolling part and the board can be moved to change its direction.

[0032] Seen in Figure 2-7 The stretching and contraction section includes two opposing hinged transverse stretching bars 330 and a mating plate 340 located on the mating bar 220 near the base 210. The mating plate 340 forms a mating groove 441 along its length. A mating shaft 531 is formed on the side of the transverse stretching bar 330 near the mating plate 340. The mating shaft 531 is used for sliding engagement with the mating groove 441. A mating hole 532 is formed through the end away from the mating shaft 531. A mating post 722 is formed on the mating bar 220. The mating post 722 is rotatably engaged with the mating hole 532.

[0033] Specifically, one end of the transverse tension bar 330 is rotatably engaged with the mating shaft 531 at the mating bar 220, and the other end is slidably engaged with the mating groove 441 at the mating plate 340. The two transverse tension bars 330 form an X-shaped structure that can rotate relative to each other. Therefore, when the two transverse tension bars 330 rotate, the two support components 100 can be moved away from and closer to each other in a better manner.

[0034] Furthermore, the mating groove 441 is a T-shaped groove, and a limiting block is formed at the end of the mating shaft 531. The limiting block is used to slide with the T-shaped groove.

[0035] Seen in Figure 2 , 3 8. The mating plate 340 is hinged to the side away from the mating strip 220 with an inclined support strip 350. The base 210 is formed with at least one snap-fit ​​groove 811 on the side close to the mating strip 220. The inclined support strip 350 and the snap-fit ​​groove 811 are correspondingly mated.

[0036] Specifically, there can be multiple snap-fit ​​slots 811, and the inclined support bar 350 can cooperate with different snap-fit ​​slots 811 according to the angle between the base 210 and the mating bar 220, thereby maintaining the relative angle between the base 210 and the mating bar 220.

[0037] Seen in Figure 3 , 8 And 9, the inclined support bar 350 forms a mating hook 951 at the end away from the mating plate 340, and the mating hook 951 is used to abut against the snap-fit ​​groove 811.

[0038] Specifically, by engaging the hook 951 with the snap-fit ​​groove 811, the stability of the engagement between the inclined support bar 350 and the snap-fit ​​groove 811 can be improved.

[0039] Seen in Figure 6 Both of the two transverse tension bars 330 have relief grooves 633 formed at their respective locations. When the two transverse tension bars 330 are engaged, the bottom of the relief grooves 633 are in a corresponding sliding engagement.

[0040] Specifically, the clearance groove 633 can prevent interference when the two transverse tension bars 330 rotate and engage.

[0041] Seen in Figure 4 and 8 A positioning pin 442 is formed on the side of the mating plate 340 near the base 210, and a positioning hole 812 is formed on the base 210 accordingly. The positioning pin 442 is used to mate with the positioning hole 812.

[0042] Specifically, the positioning pin 442 can be inserted into the positioning hole 812 when the mating bar 220 abuts against the base 210, thereby preventing the transverse tension bar 330 from sliding relative to the base 210 when the two support mechanisms are unfolded, thus better avoiding damage to the hinge joint between the transverse tension bar 330 and the base 210.

[0043] Seen in Figure 8 A support hook 813 is formed at one end of the base 210 near the hinge point with the mating strip 220. The support hook 813 extends toward the mating strip 220, so that the support hook 813 can support the plate.

[0044] Seen in Figure 3The rolling part is a rolling shaft 360, which rotates in conjunction with the mating strip 220.

[0045] Specifically, the rolling shaft 360 can abut against the plate, and when the plate rotates, the rolling shaft 360 rotates, which can better reduce friction.

[0046] Multiple mounting grooves are formed on the side of the base 210 away from the mating strip 220. Anti-slip pads are adhered to each of the multiple mounting grooves. By setting anti-slip pads, the friction between the base and the mounting surface is increased, making the base more stable when placed on the mounting surface.

[0047] Working principle:

[0048] When using this portable board holder, first separate and unfold the two support components 100, then place the board on the mating surface 221 so that the bottom of the board abuts against the support hook 813. Then rotate the mating bar 220 so that the mating bar 220 is set at an angle to the base 210. Rotate the tilting support bar 350 so that the mating hook 951 abuts against the snap-fit ​​groove 811, thereby achieving the tilted display of the board.

[0049] When the plate needs to be changed in orientation, the mating strip 220 abuts against the base 210, so that the positioning pin 442 is inserted into the positioning hole 812. At this time, the plate is set horizontally. Due to the setting of the rolling shaft 360, the plate can be rotated relatively easily to change the orientation.

[0050] Understandably, this portable board stand can be used for blackboard and whiteboard demonstrations and writing, or for placing drawing boards for drawing.

[0051] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
