Description

Technical Field

[0001] The utility model relates to a whiteboard bracket, in particular to an adjustable whiteboard bracket. Background Art

[0002] A writable whiteboard is needed in conference rooms, classrooms and other places. This whiteboard can be written on with a whiteboard pen. This whiteboard is usually fixed directly to the wall or fixed to a whiteboard bracket.

[0003] Fixing it to the wall can damage the wall's integrity and aesthetics. Some whiteboard stands have fixed dimensions and cannot be adjusted in size or height, making them suitable only for whiteboards of a specific size. Some whiteboard stands feature telescopic mechanisms that allow them to adjust in size and height to accommodate whiteboards of varying sizes. However, existing telescopic mechanisms can easily loosen during use, causing the support frame to fall apart, potentially posing a dangerous situation. Utility Model Content

[0004] The main purpose of the utility model is to provide an adjustable whiteboard bracket, which solves the technical problem that the telescopic structure of the existing whiteboard bracket is easy to loosen and fall apart during use.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an adjustable whiteboard stand, comprising a foot stand and a connecting rod;

[0006] The bottom of the tripod is connected to the ground, and a limiting bump is provided on the top of the tripod;

[0007] The four walls of the connecting rod are provided with limiting grooves, one end of which is fixed with a limiting structure, and the limiting structure is detachably connected to the limiting protrusion; a limiting protrusion is also provided on the top of the connecting rod, and a groove matching the limiting protrusion is provided on the bottom of the connecting rod. The limiting protrusion is arranged in the groove of the other connecting rod, and the limiting protrusion and the limiting structure are detachably connected;

[0008] Or the limiting protrusion is slidably connected to another connecting rod at the limiting groove.

[0009] As a preferred solution, the tripod includes a vertical rod and a horizontal board.

[0010] The bottom of the horizontal plate is connected with a universal wheel, the top of the horizontal plate is fixedly connected with the vertical rod, the four walls of the vertical rod are provided with limiting grooves, and the top of the vertical rod is provided with a limiting protrusion.

[0011] As a preferred solution, the bottoms of the two side walls of the limiting protrusion are provided with clamping plates extending toward the limiting groove, and the clamping plates are clamped with the limiting structure or the limiting groove.

[0012] As a preferred solution, the limiting structure includes a connecting plate, a latch and a spring;

[0013] One end of the connecting plate is fixedly connected to the bottom of the limiting groove, the inner side of the connecting plate has the same shape as the limiting protrusion, and the inner side of the connecting plate abuts against the limiting protrusion;

[0014] The bolt passes through the bottom of the connecting plate, the top of the bolt plate abuts against the bottom of the limiting protrusion, the rod body of the bolt is sleeved with a spring, the spring is arranged in the connecting plate, one end of the spring abuts against the bolt plate, and the other end of the spring abuts against the inner wall of the connecting plate.

[0015] The beneficial effects achieved by the utility model are:

[0016] The utility model uses a connecting rod as the main structure of the whiteboard bracket, replacing the telescopic rod structure of the traditional whiteboard bracket. The connecting rod realizes the adjustment of the vertical height and horizontal width of the whiteboard bracket by clamping the limiting protrusion with the limiting structure. The clamping method is more firm than the telescopic structure, which improves the stability of the whiteboard bracket. The connecting rod can also be used as the horizontal connecting structure of the whiteboard bracket by clamping the limiting protrusion into the limiting groove, so that the whiteboard bracket can be spliced together by using only one connecting rod, which is more convenient to use.

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1-Figure 5 As shown, the utility model discloses an adjustable whiteboard stand, comprising a tripod 1 and a connecting rod 2. The tripod 1 is used to provide support for the whiteboard stand, and the connecting rod 2 serves as a splicing structure of the whiteboard stand.

[0028] like Figure 3 As shown, the tripod 1 includes a vertical rod 14 and a horizontal plate 12. Both ends of the bottom of the horizontal plate 12 are connected to the universal wheels 13, and the vertical rod 14 is vertically fixed to the top of the horizontal plate 12. The four walls of the vertical rod 14 are each provided with a limiting groove 22. The top of the vertical rod 14 is provided with a first limiting protrusion 11. The first limiting protrusion 11 is a protruding structure. The bottom of the first limiting protrusion 11 on both opposite sides is integrally formed with a clamping plate 111 extending toward the limiting groove 22.

[0029] like Figure 4 As shown, the four side walls of the connecting rod 2 are also provided with limiting grooves 22. A limiting structure 21 is fixed at one end of two opposite limiting grooves 22, and the limiting structure 21 is detachably connected to the first limiting protrusion 11. As an embodiment, Figure 5 and Figure 6As shown, the limiting structure 21 includes a connecting plate 211, a latch 212, and a spring 213. One end of the connecting plate 211 is fixedly connected to the bottom of the limiting groove 22. The inner side of the connecting plate 211 has the same shape as the first limiting protrusion 11 and is used to abut against the first limiting protrusion 11. The latch 212 passes through the bottom of the connecting plate 211 and includes an inserting plate 2122 and a rod body 2121. The inserting plate 2122 is fixedly connected to the rod body 2121. The top of the inserting plate 2122 is flat and the bottom is inclined. The top plane of the inserting plate 2122 can abut against the bottom of the clamping plate 111. The rod body 2121 is outer-mounted with a spring 213. The spring 213 is arranged in the connecting plate 211, with one end of the spring 213 abutting against the inserting plate 2122 and the other end abutting against the inner wall of the connecting plate 211. A second limiting protrusion 24 is provided at the top of the connecting rod 2. The structure of the second limiting protrusion 24 is the same as that of the first limiting protrusion 11. Therefore, the second limiting protrusion 24 can also be spliced with the limiting structure 21 in the above manner, which will not be described in detail here. A slot 23 is provided at the bottom of the connecting rod 2 to match the first limiting protrusion 11 or the second limiting protrusion 24. The first limiting protrusion 11 or the second limiting protrusion 24 is disposed in the slot 23. Both the first limiting protrusion 11 and the second limiting protrusion 24 can slide in the limiting groove 22, and the first limiting protrusion 11 and the second limiting protrusion 24 just fit with the inner wall of the limiting groove 22.

[0030] by Figure 1 For example, this embodiment includes two tripods 1. To use, first place the tripods 1 on the ground. Then, pick up a connecting rod 2, align the slot 23 with the first stopper 11 on the top of the vertical rod 14, and press the connecting rod 2 downward. During this process, the inclined surface of the bottom of the insert plate 2122 slides over the inclined surface of the first stopper 11. When the first stopper 11 is fully embedded in the slot 23, the top surface of the insert plate 2122 coincides with the bottom surface of the retaining plate 111, thereby achieving detachable installation of the connecting rod 2 and the vertical rod 14. Obviously, simply controlling the number of connecting rods 2 can control the height of the whiteboard stand. When the connecting rod 2 needs to be installed horizontally, the second stopper 24 on the top of the connecting rod 2 is simply engaged with the stopper groove 22. When the second stopper 24 needs to be fixed in place within the stopper groove 22, it can be fixed with bolts. This bolt connection method is conventional and does not fall within the scope of the present invention, so it will not be described in detail. After the connecting rod 2 is assembled, you only need to fix the whiteboard to the side wall of the connecting rod 2.

[0031] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
