Description

Technical Field

[0001] The utility model relates to the technical field of advertising brackets, in particular to an adjustable highway advertising bracket. Background Art

[0002] With the opening of the market, manufacturers are paying more and more attention to advertising. Advertising is divided into many types, such as TV advertising, highway advertising and street sign advertising. Advertising requires the use of advertising stands to assist customers in viewing the advertising content.

[0003] At present, general advertising display stands generally use advertising boards printed on metal or wood boards, and use steel frame brackets to fix them in places with dense traffic. However, the current advertising brackets still have some disadvantages: they cannot be adjusted according to the length of the advertisement, resulting in limitations when the area of ​​the advertising board needs to be increased. Utility Model Content

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable highway advertising bracket, comprising a support rod, a positioning shaft rotatably provided on the support rod, two positive and negative thread screws symmetrically provided on the positioning shaft, two positioning seats penetrated by the screws symmetrically provided above the support rod, and a guide rod penetrating the positioning seat is provided at the upper end of the support rod, two first support rods and a second support rod are symmetrically provided on both sides of the positioning seat, the second support rod can be inserted into the interior of the first support rod, a tensioning spring is provided inside the first support rod, one end of the second support rod can be inserted into the interior of the first support rod and connected to one end of the tensioning spring, and a positioning seat is fixedly provided on the other end of the second support rod The cam is secured to a position within the locking cam and secured to a location where the cam has been locked.

[0008] In order to facilitate the operation of the positioning shaft, the present invention has been improved in that the lower end of the positioning shaft is provided with a toggle block located below the support rod.

[0009] Furthermore, the present invention is improved in that the clamping block is made of a non-slip rubber block.

[0010] Furthermore, the present invention is improved in that anti-slip grooves are provided on the inner wall of the limiting groove.

[0011] Furthermore, the present invention is improved in that the positioning seat, the first support rod, the second support rod and the positioning frame are all made of metal.

[0012] Furthermore, the present invention is improved in that the positioning seat, the first support rod, the second support rod and the positioning frame are all made of aluminum alloy.

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the utility model provides an adjustable highway advertising bracket with the following beneficial effects:

[0015] The adjustable highway advertising stand has multiple positioning frames fixed at the four corners of the advertising cloth. At this time, the tensioning spring can still provide an elastic force to the second support rod, so that the advertising cloth is tensioned in the horizontal direction. Further rotation of the positioning shaft can make the two positioning seats move synchronously in different directions on the two screws through the action of the threaded structure, thereby tensioning the advertising cloth in the vertical direction, making the advertising cloth spread out smoothly, and being able to be freely adjusted according to the length of the advertising cloth, with few limitations during use.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] See also Figure 1-6 , the utility model is an adjustable highway advertising bracket, including a support rod, a positioning shaft 2 is rotatably set on the support rod, two positive and negative thread screws 3 are symmetrically set on the positioning shaft 2, two positioning seats 5 penetrated by the screws 3 are symmetrically set above the support rod, and the upper end of the support rod is provided with a guide rod 4 penetrating the positioning seat 5, two first support rods 6 and second support rods 7 are symmetrically set on both sides of the positioning seat 5, the second support rod 7 can be inserted into the interior of the first support rod 6, the interior of the first support rod 6 is provided with a tensioning spring, one end of the second support rod 7 can be inserted into the interior of the first support rod 6 and connected to one end of the tensioning spring, the other end of the second support rod 7 is fixedly provided with a positioning frame 8, and a limiting slot 9 is provided on the positioning frame 8. A positioning slot and a clamping rod 10 passing through the positioning slot are provided at the rear end of the positioning frame 8. One end of the clamping rod 10 is provided with a clamping block 11 located inside the limiting slot 9. A card slot 12 and a hollow slot 14 are provided on the inner wall of the positioning slot. A first cavity is provided on the clamping rod 10. A first spring is provided inside the first cavity. One end of the first spring is provided with a card block 13 that cooperates with the card slot 12. Second cavities 18 are provided on both sides of the hollow slot 14. A second spring is provided inside the second cavity 18. A push plate 16 is provided on one side of the positioning frame 8.
