Description

Technical Field

[0001] The utility model relates to the technical field of plate display, and relates to a trailer display rack. Background Art

[0002] Nowadays, the use of display racks has been very common. In addition to the display of some artworks, it also includes the display of commodities for supermarkets, stores, and exhibitions, especially the display of some plate-shaped items. The existing plate display racks are of a complete set structure, with large volume, being not only heavy but also inconvenient for transportation. The display of plates is rigid and immovable, resulting in poor display effects.

[0003] Patent No. CN208863948U discloses a vertical plate display rack in the technical field of display racks, including a base. The left and right sides of the top of the base are respectively installed with a vertical rod and a U-shaped fixing rod. A moving rod is slidably arranged in the inner cavity of the U-shaped fixing rod. The bottom of the moving rod is connected to the bottom of the inner cavity of the U-shaped fixing rod through a compression spring. A groove is transversely formed in the moving rod, and a moving block is slidably arranged in the groove. A pressing block is installed on the left side of the moving block. By rotating the adjusting bolt, the adjusting bolt moves rightward in the threaded hole and presses the pressing block, causing the moving block to move in the groove, and then the pressing block is squeezed into the groove. Under the elastic recovery of the compression spring, the moving rod moves upward, and the pressing block moves into another clamping groove in the sliding groove. Under the elastic recovery of the pressing spring, the pressing block is bounced into the clamping groove for clamping, so that the moving rod moves upward, and the display board is displayed at a certain inclination angle, improving the display effect.

[0004] The above vertical plate display rack has the following technical problems: The size of the vertical plate display rack is fixed and cannot be adjusted according to the actual sizes of different plates, resulting in poor applicability. Summary of the Utility Model

[0022] The following combines the embodiments and the attached Figures 1 to 4 , and further elaborates on the technical solutions of the present invention.

[0023] Embodiment 1

[0024] A trailer display rack includes a trailer frame 1 and universal wheels 2 provided at the lower end of the trailer frame 1. The trailer frame 1 includes a first frame 11 and a second frame 12. A pin slot 111 is provided at the side end of the first frame 11, and a pin 121 for cooperating with the pin slot 111 is provided at the side end of the second frame 12. A locking device 3 is provided between the first frame 11 and the second frame 12. The locking device 3 includes a locking arm 31 fixedly provided on the side wall of the first frame 11 and a locking mechanism 32 provided on the second frame 12. The locking mechanism 32 includes a limit seat 321 fixedly provided on the side wall of the second frame 12 and an elastic locking component 322 provided on the limit seat 321. The locking arm 31 is slidably provided in the limit seat 321, and a plurality of first locking holes 311 are linearly arranged at the upper end.

[0025] Such as Figures 1 to 6As shown in the figure, the structure of the utility model is simple. During actual use, the board is placed on the trailer frame 1 for display. During the display process, it is convenient to move and pick up the board. At the same time, the trailer frame 1 can be adjusted according to the actual size of the board to meet the placement requirements of boards of different sizes and improve the applicability of the equipment.

[0026] There are three groups of mutually matching pin slots 111 and pins 121 arranged between the first frame 11 and the second frame 12, which improves the stability and load-bearing capacity of the equipment.

[0027] During the adjustment process, first release the locking of the locking arm 31 by the elastic locking component 322. After unlocking, adjust the frame according to the actual use requirements. After the adjustment is completed, lock the locking arm 31 through the elastic locking component 322. The structure is simple and the operation is convenient, avoiding the displacement between the first frame 11 and the second frame 12 due to external force during use.

[0028] As a further preferred embodiment, the elastic locking component 322 includes a locking cross plate 3221 fixedly arranged on the limit seat 321 and a locking pin 3222 arranged on the locking cross plate 3221. A second locking hole 32211 is penetrated through the middle of the locking cross plate 3221. The locking pin 3222 includes a first locking pin 32221 fixedly arranged on the locking cross plate 3221 and a second locking pin 32222 slidably arranged at the lower end of the first locking pin 32221. The second locking pin 32222 is slidably arranged in the second locking hole 32211. A locking spring 32223 is arranged between the first locking pin 32221 and the second locking pin 32222. A limit plate 41 is fixedly arranged in the middle of the second locking pin 32222. The upper end of the locking spring 32223 abuts against the second locking hole 32221, and the other end abuts against the limit plate 41.

[0029] Specifically, during actual use, the lower end of the second locking pin 32222 is inserted into the first locking hole 311 of the locking arm 31 under the action of the locking spring 32223, avoiding the relative displacement between the frames caused by the separation of the second locking pin 32222 from the first locking hole 311 during use.

[0030] As a further preferred embodiment, a dial plate 411 is arranged at the front end of the limit plate 41 and limit holes 412 are arranged at both ends. Guide rods 42 fixedly connected to the locking cross plate 3221 are arranged on both sides of the first locking pin 32211. The guide rods 42 are arranged in the limit holes 412.

[0031] Specifically, as Figure 4As shown, during actual use, the second locking pin 32222 is driven to move by the dial plate 411, which facilitates the operation of the staff. At the same time, the guide rod 42 is used to guide the second locking pin 32222, improving the stability of the second locking pin 32222 during movement.

[0032] As a further preferred embodiment, a placement rack 51 for placing display boards is provided inside both the first vehicle frame 11 and the second vehicle frame 12, and handles 52 are provided inside both the first vehicle frame 11 and the second vehicle frame 12.

[0033] Specifically, as Figure 5 shown, during actual use, the display mode combined with multiple trailer frames 1 and a transparent display cover is convenient for carrying and taking the display board.

[0034] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
