[0002] Billboards are a signal tool in the pulling system to start the next production process or to transport the finished product to the downstream process. Billboards refer to all outdoor media that convey advertising information, and the size of the media depends on the actual environment.

[0003] Billboards are often used for shop signs, door heads and facades. The images can be hand-painted, computer-made or printed on paper. Billboards are generally made of square tubes, angle steels and other materials welded together. Billboards include three-dimensional boards, light cloth, blister, car paint, gussets and aluminum-plastic boards, etc.

[0004] The patent document with publication number CN219085627U discloses a lower clamping assembly and an upper clamping assembly of a promotional billboard mounting frame, the width of which can be adjusted according to the width of the billboard to be fixed, and the adjustment is relatively convenient and quick. The flexible billboard can be fixed by cooperating with the adjustable fixing rod assembly and the horizontal column of the clamping assembly. When the threaded column is rotated, the position of the slider on the threaded column can be changed, thereby changing the distance between the upper clamping assembly and the lower clamping assembly, which is conducive to the use of billboards of different heights. When fixing a board-type billboard, the billboard can be directly clamped in the baffles of the lower clamping assembly and the upper clamping assembly. The device has a simple structure, and both the height and width can be adjusted, which is conducive to fixing billboards of different sizes. It is easy to use and can fix both flexible and board-type billboards, which is conducive to the use of supermarkets, exhibitions and other places. The device has rich usage scenarios and a wide range of applications, and is easy to promote and use.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The lower clamping assembly and the upper clamping assembly of the existing billboard mounting frame are mainly controlled by rotating one end of the threaded column at the top of the column. In actual use, it is easy to be affected by the situation that the billboard is too high, the staff is short and the column is long, which increases the difficulty of adjusting the distance between the lower clamping assembly and the upper clamping assembly and reduces the construction efficiency of the staff. Utility Model Content

[0007] In order to overcome the problems that the existing billboard mounting frame is easily affected by the billboard being too high, the staff being short in height and the pillar being long, the difficulty of adjusting the distance between the lower clamping assembly and the upper clamping assembly is increased, and the insufficient construction efficiency of the staff is reduced, an embodiment of the present application provides a billboard mounting frame, which is configured to rotate a control hand wheel at the top of the base so that the control hand wheel drives a gear to rotate, and drives another gear to drive the prism rod to rotate, so that the threaded rods processed at both ends of the linkage rod rotate synchronously, and the threaded connection relationship between the two threaded rods and the two support pillars is adjusted respectively, so that the billboard can be clamped and fixed, which is more convenient and has higher applicability.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A billboard mounting frame includes a column and a clamping structure, wherein two clamping structures are provided and symmetrically arranged at the top and bottom of the column;

[0010] Among them, a linkage rod is arranged inside the column, and threaded rods are processed at both ends of the linkage rod. Two gears are arranged at one end of one of the threaded rods, and the two gears are meshed with each other. A control handwheel is plug-in connected to the top of one of the gears.

[0011] In one possible implementation, the top of the column is assembled and connected with a cover, the threads of the two threaded rods are in opposite directions, one end of one threaded rod is processed with a round rod, and one end of the other threaded rod is processed with a prismatic rod, the round rod is rotatably connected to the inside of the cover, and the prismatic rod is pin-connected to the inside of a gear.

[0012] In a possible implementation, the two clamping structures each include a support column, both ends of the support column are slidably connected to a movable slide, and a positioning plate is processed on a surface of one side of the movable slide.

[0013] In a possible implementation, a plurality of positioning holes are processed inside the support column, and a limiting pin passing through one of the positioning holes is arranged inside the movable slide.

[0014] In a possible implementation, both ends of the column are processed with grooves, the middle parts of the support columns on the two clamping structures are respectively threadedly connected to the outside of the two threaded rods, and the support columns are slidably connected to the inside of the grooves.

[0015] In a possible implementation, the column is internally pin-connected with two limit strips, a ring groove is processed in the middle of the linkage rod, the two limit strips are respectively located on both sides of the linkage rod, and one side of each limit strip is located inside the ring groove, thereby limiting the linkage rod from moving up and down inside the column.

[0016] In a possible implementation, a base is provided at the bottom of the column, a stop frame is processed at the center of the top of the base, and the bottom of the column is assembled and fixed to the stop frame by bolts.

[0027] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0028] Embodiment 1:

[0029] This embodiment introduces a specific structure of a billboard installation frame. Figure 1-Figure 5 As shown, it includes a column 3 and two clamping structures 2, and the two clamping structures 2 each include a support column 202, and both ends of the support column 202 are slidably connected to a movable slide 201, and a positioning plate 203 is processed on the surface of one side of the movable slide 201;

[0030] The two clamping structures 2 are symmetrically arranged at the top and bottom of the column 3. When installing the billboard, the movable slide 201 is controlled to slide outside the support column 202 to adjust the distance between the two movable slides 201 on one support column 202, and then the billboard is placed inside the two positioning plates 203 of the bottom clamping structure 2. When the two clamping structures 2 are controlled to approach each other, the billboard can be clamped and fixed.

[0031] Secondly, in order to facilitate the fixing of the support column 202 and the movable slide 201, the distance between the two movable slides 201 is ensured to be fixed. Figure 2 As shown, a plurality of positioning holes 8 are processed inside the support column 202, and a limiting pin 204 is arranged inside the movable slide 201. By passing one end of the limiting pin 204 through a positioning hole 8 and plugging it into the movable slide 201, the movable slide 201 can be fixed to the support column 202.

[0032] like Figures 1 to 3 As shown, a linkage rod 12 is disposed inside the column 3, and threaded rods 11 are processed at both ends of the linkage rod 12. Two gears 15 are disposed at one end of one threaded rod 11, and a control hand wheel 9 is plug-connected to the top of one gear 15;

[0033] Wherein, both ends of the column 3 are processed with a groove 4, the two gears 15 mesh with each other, the threads of the two threaded rods 11 are in opposite directions, and the middle parts of the support columns 202 on the two clamping structures 2 are respectively threadedly connected to the outside of the two threaded rods 11. When a gear 15 is driven to rotate by the control hand wheel 9 at the bottom of the column 3, the other gear 15 drives the threaded rod 11 to rotate, and the threaded connection relationship between the two threaded rods 11 and the two support columns 202 is adjusted, the support columns 202 can be slidably connected to the inside of the groove 4, thereby adjusting the distance between the two clamping structures 2;

[0034] Secondly, in order to ensure the stability of the control hand wheel 9 driving the two threaded rods 11 to rotate through the two gears 15, as shown in FIG. Figure 3 and Figure 5As shown, the top of the column 3 is assembled and connected with the cover 1, one end of a threaded rod 11 is processed with a round rod 10, and one end of another threaded rod 11 is processed with a prismatic rod 13, and the prismatic rod 13 is pin-connected to the inside of a gear 15. When the gear 15 is controlled to drive the threaded rod 11 to rotate, the round rod 10 can be rotatably connected to the inside of the cover 1;

[0035] Furthermore, in order to limit the upward and downward movement of the linkage rod 12 inside the column 3, the longitudinal position of the linkage rod 12 is fixed, so that the two clamping structures 2 can clamp the billboard stably. Figures 2 to 4 As shown, two limit bars 5 are pin-connected inside the column 3, and a ring groove 14 is processed in the middle of the linkage rod 12. By making the two limit bars 5 located on both sides of the linkage rod 12 respectively, and making one side of the limit bar 5 located inside the ring groove 14, the linkage rod 12 can be prevented from moving up and down inside the column 3;

[0036] Further, in order to facilitate the erection of the column 3 on the ground, as shown in FIG. Figure 1 and Figure 2 As shown, a base 6 is provided at the bottom of the column 3, and a retaining frame 7 is processed at the center of the top of the base 6. By assembling and fixing the bottom of the column 3 with the retaining frame 7 through bolts, the column 3 and the base 6 can be fixed, and the base 6 is laid on the ground, which is conducive to the vertical placement of the column 3;

[0037] At the same time, the two gears 15 are both retractably connected to the inside of the base 6. By making the top of the gear 15 sink into the inside of the base 6, it is possible to prevent the surface of the base 6 from bulging toward the top.

[0038] Specifically, when using the billboard mounting frame to install the billboard:

[0039] First, the movable slide 201 is controlled to slide outside the support column 202, the distance between the two movable slides 201 on one support column 202 is adjusted, and the two limit pins 204 are respectively passed through the inside of the two positioning holes 8 to fix the movable slide 201 and the support column 202;

[0040] Then, the billboard is placed inside the two positioning plates 203 of the bottom clamping structure 2, so that the back of the billboard fits with the surface of the column 3 and the movable slide 201;

[0041] Next, the control hand wheel 9 is rotated at the top of the base 6, so that the control hand wheel 9 drives a gear 15 to rotate, and another gear 15 drives the threaded rod 11 connected to the prism rod 13 to rotate. Since one end of the threaded rod 11 is processed with a linkage rod 12 with another threaded rod 11, the threaded connection relationship between the two threaded rods 11 and the two support columns 202 can be adjusted synchronously. When the support column 202 slides inside the groove 4, the distance between the two clamping structures 2 is adjusted, so that the billboard is clamped and fixed.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
