[0034] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] This utility model discloses a bulletin board support leg, which includes a ground-inserting rod 1, a main rod 2, and connecting bolts 3, for supporting and fixing the bulletin board. The support leg structure is a ground-inserting support leg structure, which is used for installation in relatively soft ground environments. The texture of this environment is relatively soft compared to hardened ground or stone surface, rather than the softness of wet ground, so as to achieve stable support for the bulletin board.

[0036] like Figure 1 and Figure 2 As shown, the ground-inserting rod 1 has a hollow structure and is used to insert into relatively soft ground. The main rod 2 can be the main frame of the bulletin board or it can be fixedly connected to the bulletin board. When installing the bulletin board, first insert the ground-inserting rod 1 into the ground, then insert one end of the main rod 2 into the ground-inserting rod 1, and finally place the connecting bolt 3 between the ground-inserting rod 1 and the main rod 2. The ground-inserting rod 1 and the main rod 2 can be fixed by using the connecting bolt 3.

[0037] This ground-mounted support structure eliminates the need for precast concrete foundations at the installation location of the bulletin board, greatly improving the installation efficiency.

[0038] The connecting bolts 3 securely connect the ground rod 1 and the main rod 2, facilitating easy assembly and disassembly and enabling quick replacement of the bulletin board, thus improving its practicality.

[0039] like Figure 2 As shown, a V-shaped groove 101 is provided at the bottom of the ground-inserting pole 1. The V-shaped groove 101 forms two pointed parts 102 on the originally flat lower end surface of the ground-inserting pole 1, making it easier for the ground-inserting pole 1 to be inserted into the ground. At the same time, the two pointed parts 102 are arranged opposite to each other about the axis of the ground-inserting pole 1. When the ground-inserting pole 1 is inserted into the ground, the ground-inserting pole 1 will not shift laterally, thus ensuring the accuracy of the installation position of the ground-inserting pole 1 and the bulletin board.

[0040] like Figure 2 , Figure 4 and Figure 5 As shown, the ground-inserting pole 1 includes a first pole body 11 and a first ring plate 12, and the main pole 2 includes a second pole body 21 and a second ring plate 22. A V-groove 101 is formed at the end of the first pole body 11. The first ring plate 12 is fixedly disposed at the end of the first pole body 11 away from the V-groove 101. One end of the second pole body 21 is disposed inside the first pole body 11. The second ring plate 22 is fixedly disposed on the second pole body 21 and is fixedly connected to the first ring plate 12 by connecting bolts 3. Allowing the first ring plate 12 and the second ring plate 22 to cooperate with the connecting bolts 3 can improve the connection convenience and fixing reliability between the ground-inserting pole 1 and the main pole 2.

[0041] The connecting bolt 3 includes a threaded rod 31 and a nut 32, such as Figure 3As shown, the second ring plate 22 has an assembly hole 201, the screw 31 passes through the assembly hole 201, and one end of the screw 31 is fixedly set on the first ring plate 12. The nut 32 is connected to the screw 31 by thread engagement and abuts against the side of the second ring plate 22 away from the first ring plate 12, so as to realize the fixation of the first ring plate 12 and the second ring plate 22. Since the screw 31 is directly fixed on the first ring plate 12, the assembly efficiency of the connecting bolt 3 can be improved.

[0042] To improve the fixing firmness and stability of the connecting bolts 3 to the ground rod 1 and the main rod 2, it is preferable to set multiple mounting holes 201 and multiple connecting bolts 3, with each mounting hole 201 corresponding to a different connecting bolt 3, and the multiple mounting holes 201 arranged in a circumferential array around the axis of the ground rod 1.

[0043] In some embodiments, the cross-sections of both the ground-inserting pole 1 and the main pole 2 are circular or rectangular to accommodate different types of bulletin boards.

[0044] In some embodiments, the length of the second rod 21 is 700mm, the second ring plate 22 is disposed in the middle position of the second rod 21, the length of the first rod 11 is 800mm, and the depth of the V-groove 101 is 400mm. It can be seen that the length of the second rod 21 inserted into the first rod 11 is 350mm. The end of the main body rod 2 located in the ground-inserting rod 1 is spaced 50mm from the V-groove 101, so that the end of the second rod 21 is not located in the V-groove 101. This not only ensures the connection strength between the ground-inserting rod 1 and the main body rod 2, but also prevents the soil in the ground from hindering the assembly of the second rod 21.

[0045] In actual processing, certain processing errors will occur. In order to avoid the second rod 21 being unable to be inserted into the first rod 11, the outer diameter of the second rod 21 should be smaller than the inner diameter of the first rod 11. Similarly, the inner diameter of the assembly hole 201 should also be slightly larger than the outer diameter of the screw 31 to ensure that the screw 31 can be smoothly inserted into the assembly hole 201.

[0046] During the installation of the ground-inserting pole 1, due to installation errors and other factors, the ground-inserting pole 1 may become crooked, affecting the connection between the ground-inserting pole 1 and the main pole 2, as well as the installation accuracy of the bulletin board.

[0047] To solve the above problems, adjusting bolts 4 are provided, and threaded holes 202 are made on the second ring plate 22. The adjusting bolts 4 are connected to the threaded holes 202 through threaded engagement and abut against the top side of the first ring plate 12. Multiple adjusting bolts 4 and threaded holes 202 are provided, and they correspond one-to-one. When the ground-inserting rod 1 is inserted into the ground and the main body rod 2 is inserted into the ground-inserting rod 1, the verticality of the main body rod 2 can be adjusted by rotating each adjusting bolt 4. After the verticality of the main body rod 2 is adjusted, the ground-inserting rod 1 and the main body rod 2 are fixed by the connecting bolts 3.

[0048] like Figure 3 As shown, the number of threaded holes 202 and assembly holes 201 are the same, and the threaded holes 202 and assembly holes 201 are alternately arranged, thereby improving the connection stability and adjustment stability between the ground insertion rod 1 and the main body rod 2.

[0049] The method of using a bulletin board support leg according to this utility model is as follows:

[0050] First, insert the lower end of the first rod 11 into the ground. Then, insert the lower end of the second rod 21, which is fixedly connected to the bulletin board, into the upper end of the first rod 11. Insert the screw 31 into the corresponding mounting hole 201. Next, adjust the level of the second ring plate 22 by rotating the adjusting bolts 4 to make the second rod 21 vertical. Finally, screw the nut 32 onto the screw 31 so that the nut 32 abuts against the top side of the second ring plate 22 to connect the main rod 2 with the ground-inserting rod 1 and fix the bulletin board.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
