DETAILED DESCRIPTION

[0030] The utility model will be further explained in connection with the drawings and in connection with examples.

[0031] Example:

[0032] As Figures 1-7 shown, a glass whiteboard includes support 1 and panel 2 installed on support 1, support 1 includes two support rods 3 arranged at left and right intervals, panel 2 includes board piece 4 and at least frame 5 fixed on the left and right sides of board piece 4, two support rods 3 are each provided with first fixed hole position 6, further including

[0033] Preposition structure includes pre-hanging groove 8 and positioning sleeve 9 connectable to pre-hanging groove 8, positioning sleeve 9 is through at both ends, and positioning sleeve 9 is provided with threaded inner hole 10;

[0034] First fastener 12 is connected with frame 5 and is threadedly connected with threaded inner hole 10 at one end of positioning sleeve 9, so that positioning sleeve 9 is fixedly connected with frame 5;

[0035] Frame 5 at left and right sides is each provided with positioning sleeve 9, and two support rods 3 are each provided with pre-hanging groove 8;

[0036] When positioning sleeve 9 is connected to pre-hanging groove 8 one by one, first fixed hole position 6 on two support rods 3 is aligned with threaded inner hole 10 at the other end of positioning sleeve 9 one by one, and second fastener 11 is threadedly connected with positioning sleeve 9 through first fixed hole position 6 of support rod 3, so that panel 2 is fixedly connected with support 1.

[0037] The pre-positioning structure of the glass whiteboard of the embodiment includes the positioning sleeve 9 and the pre-hanging groove 8. When the mounting panel 2 is installed, the positioning sleeve 9 is connected to the pre-hanging groove 8, so that both hands are released, and the whiteboard does not need to be lifted, which is very convenient, labor-saving, safe, and easy to install. When the positioning sleeve 9 is connected to the pre-hanging groove 8, the threaded inner hole 10 of the positioning sleeve 9 installed on the frame 5 is aligned with the first fixing hole 6 of the support rod 3, so that the mounting hole of the frame 5 is quickly positioned with the mounting hole of the support rod 3, and the second fastener 11 is easily screwed into the first fixing hole 6 and the threaded inner hole 10, which further facilitates the installation. In addition, the mounting hole of the frame 5 is transferred to the positioning sleeve 9, so that the second fastener 11 is blocked by the first fastener 12 and is not directly screwed into the frame 5, so that the panel 2 is not easily damaged during installation.

[0038] In the embodiment, the up, down, left, and right directions are used as the reference, a reinforcing rod 20 is further connected between the two support rods 3, and a universal wheel assembly 21 is further arranged at the bottom of each support rod 3. The upper side, lower side, left side, and right side of the panel 4 are surrounded by the frame 5. Figure 1

[0039] The left and right frames 5 are provided with the second fixing hole 7, and the first fastener 12 is screwed into the threaded inner hole 10 at one end of the positioning sleeve 9 after passing through the second fixing hole 7 of the frame 5. This structure facilitates the connection of the first fastener 12 with the frame 5 and the positioning sleeve 9.

[0040] The threaded end of the first fastener 12 passes through the second fixing hole 7 from the inside to the outside and extends out of the frame 5. This structure allows the first fastener 12 to be tightened towards the outside of the frame 5, so that the panel 2 is less likely to be damaged during installation.

[0041] The pen holder 13 and the lock piece 14 are further included. The lock piece 14 is provided with a clamping hook 15 at one end and a third fixing hole 16 at the other end. The frame 5 surrounds the lower side of the panel 4 and is provided with a clamping groove 17 on the side. The pen holder 13 is provided with a fourth fixing hole 18. When the clamping hook 15 is connected to the clamping groove 17, the third fixing hole 16 is aligned with the fourth fixing hole 18, and the pen holder 13 is fixed to the lower side of the frame 5 by the third fastener 19. The arrangement of the lock piece 14 also changes the locking position and direction of the third fastener 19. Originally, the third fastener 19 was vertically downward and needed to be punched on the frame 5, which had a very narrow installation space and was easy to damage the panel 2. Now, the third fastener 19 is perpendicular to the direction of the panel 2 and does not directly punch on the panel 2. Not only is the installation space not limited, but the locking is also easier, and the panel 2 is less likely to be damaged.

[0042] The lock piece 14 is provided with multiple clamping hooks 15 and is arranged along the length direction of the pen holder 13. This structure makes the pen holder 13 more firmly fixed to the frame 5. ​

[0043] The fourth fixing hole 18 is located below the panel 2, and the third fastener 19 is screwed into the fourth fixing hole 18 in a direction perpendicular to the panel 2. This arrangement allows the third fastener 19 to be screwed in a direction perpendicular to the panel 2 without hitting the panel 2, thereby further facilitating installation and further avoiding damage to the panel 2.

[0044] The left and right sides of the pen holder 13 are also fixed to the two support rods 3 by fourth fasteners 22. In this embodiment, two fourth fasteners 22 are arranged on the left and right sides of the pen holder 13 respectively, and there are a total of four fourth fasteners 22. This arrangement allows the left and right sides of the pen holder 13 to be fixed to the support rods 3, making the pen holder 13 more secure, and also allowing the pen holder 13 to become part of the stand 1, thereby providing stable support for the panel 2.

[0045] The pen holder 13 is supported at the bottom of the panel 2. This arrangement allows the pen holder 13 to provide support, making the panel 2 more secure.

[0046] The lock piece 14 is U-shaped and one end is longer than the other end. The longer end of the lock piece 14 is provided with a third fixing hole 16, and the other end is provided with a hook 15. The two ends of the lock piece 14 are arranged to be of different lengths, so that after hanging, the hook 15 and the third fixing hole 16 have a height difference, and the third fixing hole 16 is away from the position where the panel 2 is located.

[0047] The support rod 3 is hollow inside, the pre-hanging groove 8 is arranged on the inner side of the support rod 3, and the positioning sleeve 9 is installed inside the support rod 3. The left and right sides of the frame 5 are fixed between the two support rods 3 by the second fasteners 11 and the positioning sleeves 9. This arrangement allows the pre-positioning structure to be hidden inside the support rod 3, making the overall structure more compact and simple.

[0048] The upper end of the pre-hanging groove 8 is open, and is used to hang the positioning sleeve 9 from top to bottom on the pre-hanging groove 8. This arrangement allows the positioning sleeve 9 to be hung on the pre-hanging groove 8 through the opening, making installation more convenient and labor-saving.

[0049] The top end of the support rod 3 is detachably connected with an end cap 23. After the positioning sleeve 9 is hung on the pre-hanging groove 8, the end cap 23 is used to close the opening at the upper end of the pre-hanging groove 8, so that the positioning sleeve 9 is reliably limited in the pre-hanging groove 8 and is not easy to fall off.

[0050] The pre-hanging groove 8 is U-shaped. The U-shaped pre-hanging groove 8 has a simple structure and is easy to process.

[0051] In this embodiment, the installation process of the glass whiteboard is as follows:

[0052] (1) Stand 1 installation: Assemble the support rod 3, the reinforcing rod 20 and the universal wheel assembly 21 into the stand 1.

[0053] (2) Positioning sleeve 9 installation: the positioning sleeve 9 is fixed on the frame 5 of the left and right sides of the panel 2 by the first fastener 12 from inside to outside through the second fixed hole 7 and tightened in the threaded inner hole 10 at one end;
