Description

Technical Field

[0001] The utility model relates to the field of liquid crystal displays, and in particular to a liquid crystal display transportation protection device. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to form a picture with the back light tube. IPS, TFT, and SLCD are all subcategories of LCD. Their working principle is that under the action of the electric field, the arrangement direction of liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction in the time domain and space domain through the three primary color filters of red, green, and blue.

[0003] Since LCD monitors are fragile products, they are usually wrapped in packaging boxes during transportation and storage. The packaging boxes are usually made of paper boxes and foam boards inside. However, since the packaging boxes and the LCD monitors inside must be intact during transportation, LCD monitor transportation protection devices are often used. Currently, most LCD monitors are stacked and placed at intervals on pallets to prevent them from being squeezed. However, when transported by pallet, the LCD monitors placed inside the pallet are in a free state, so they are prone to shaking inside the pallet, which is not conducive to the protection of the LCD monitors and the packaging boxes on their surfaces.

[0004] Therefore, we make improvements on this and propose a liquid crystal display transportation protection device. Utility Model Content

[0005] The utility model aims to provide a liquid crystal display transportation protection device, which solves the problem that the liquid crystal display placed in the existing liquid crystal display transportation protection device shakes when in use, which is not conducive to protection.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A liquid crystal display transportation protection device comprises a frame for loading the liquid crystal display, wherein both sides of the frame are slidably equipped with a contact plate, and one side of the contact plate is connected to a spring fixed to the frame, and the inner side of the contact plate is connected to a limit assembly for secondary protection of the liquid crystal display;

[0008] A sliding surface is formed on the top of one side of the contact plate, and a contact surface is formed on the bottom of one side of the contact plate, and a transition is formed at the connection between the contact surface and the sliding surface to form an arc surface;

[0009] The limiting assembly comprises a tooth plate connected to the inner side of the abutment plate, gears distributed on both sides of the tooth plate and meshing therewith, and a support rod fixed at the center of the gear and rotatably connected to the bottom wall of the frame, wherein the limiting plate is connected to the support rod.

[0010] As a preferred technical solution of the present application, the limiting plate is a strip plate fixed on the support rod, and the surface of the strip plate is wrapped with an elastic insulating rubber strip.

[0011] As a preferred technical solution of the present application, a stabilizing plate fixed to the side wall of the frame is slidably inserted into one end of the tooth plate.

[0012] As a preferred technical solution of the present application, a cover plate fixed to the frame is provided above the limit assembly, and the top end of the support rod passes through the cover plate to fix the limit column.

[0013] As a preferred technical solution of the present application, a hexagonal limiting groove is formed in the limiting column, and hexagonal limiting blocks corresponding to the hexagonal limiting groove are symmetrically distributed on both sides of the lower surface of the frame.

[0014] As a preferred technical solution of the present application, handle grooves are provided on both sides of the frame, and chamfers are formed at the four corners of the outer side of the frame.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the scheme of this application:

[0017] 1. Through the set contact plate, when the LCD is placed in the frame, the sliding surface is subjected to a force so that the two contact plates are separated from each other. When the LCD is completely placed in the inner contact surface of the contact plate, the force of the spring can realize the positioning protection of the LCD, making it less likely to shake;

[0018] 2. Through the setting of the limit assembly, when the resistance plate moves away from the sliding process, the gear will drive the gear and the support rod on it to rotate, so that the strip plate is unfolded outside the cover plate to form a protection above the LCD display, reducing the problem of objects directly piled up on the surface of the LCD display and easily causing damage to it;

[0019] And multiple frames are stacked so that the hexagonal limit blocks are placed in the corresponding hexagonal limit grooves to lock the strip plate and the contact plate, thereby further ensuring the stable transportation of the LCD display. When the LCD display is placed or taken out, the limit assembly can be rotated and reset, which is convenient for the subsequent placement and transportation of the LCD display.

Such terms are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] like Figures 1-5 As shown, this embodiment proposes a liquid crystal display transportation protection device, including a frame 10 for loading a liquid crystal display 11, both sides of the frame 10 are slidably equipped with a contact plate 12, and one side of the contact plate 12 is connected to a spring 13 fixed to the frame 10, and the inner side of the contact plate 12 is connected to a limit assembly 14 for secondary protection of the liquid crystal display 11. The surface of the liquid crystal display in this embodiment is wrapped with a packaging box, a sliding surface 120 is formed on the top of one side of the contact plate 12, a contact surface 121 is formed on the bottom of one side of the contact plate 12, and an arc surface 122 is formed at the transition between the contact surface 121 and the sliding surface 120;

[0035] like Figure 2 As shown, the LCD 11 is placed above the two contact plates 12. Since the distance between the two contact plates 12 is smaller than the width of the LCD 11, the LCD 11 will first contact the sliding surface 120 on the contact plate 12 when it moves downward. Moreover, since the sliding surface 120 is an inclined surface, the contact plates 12 subjected to the contact force will move away from each other during the process of the LCD 11 being pressed downward until the LCD 11 completely slides into the opposite sides of the two contact plates 12. At this time, the spring action of the compressed rear spring 13 allows the contact plate 12 to contact the outer side of the LCD 11, thereby stabilizing the LCD 11 and preventing it from shaking greatly during transportation in the frame 10, which is beneficial to the protection of the LCD 11.

[0036] The limiting assembly 14 comprises a tooth plate 140 connected to the inner side of the abutment plate 12, gears 141 distributed on both sides of the tooth plate 140 and meshing therewith, and a support rod 142 fixed at the center of the gear 141 and rotatably connected to the bottom wall of the frame 10, a limiting plate is connected to the support rod 142, and the limiting plate is a strip plate 143 fixed on the support rod 142, and the surface of the strip plate 143 is wrapped with an elastic insulating rubber strip 144, and a stabilizing plate 145 fixed to the side wall of the frame 10 is slidably inserted at one end of the tooth plate 140;

[0037] Above the limiting component 14, there is a cover plate 15 fixed to the frame body 10. The top end of the support rod 142 penetrates through the cover plate 15 and is fixed with a limiting post 16. A hexagonal limiting groove 17 is formed in the limiting post 16, and hexagonal limiting blocks 18 corresponding to the hexagonal limiting groove 17 are symmetrically distributed on both sides of the lower surface of the frame body 10.

[0038] During the process of the above liquid crystal display 11 sliding away from each other under the pressing of the contact plates 12, the contact plates 12 will drive the toothed plate 140 to slide on the surface of the stabilizing plate 145. The toothed plate 140 meshes with the adjacent gear 141, so that the support rod 142 thereon drives the strip plate 143 to flip to form a state as shown in Figure 2 Shown in the figure. Through multiple unfolded strip plates 143, a support can be formed above the liquid crystal display 11, reducing the problem that the items above are directly pressed on the surface of the liquid crystal display and easily causing damage to it.

[0039] As shown in Figure 3 Shown in the figure, when multiple frame bodies 10 are stacked, the hexagonal limiting blocks 18 below the adjacent frame bodies 10 exactly correspond to the hexagonal limiting grooves 17 above the adjacent frame bodies 10. The hexagonal limiting blocks 18 are inserted into the corresponding hexagonal limiting grooves 17 to form a lock on the strip plate 143 and the contact plate 121. Thus, it can further ensure the stable transportation of the liquid crystal display 11. When the liquid crystal display 17 is taken out, the limiting component can be rotated and reset under the action of the spring 13, facilitating the subsequent placement and transportation of the liquid crystal display 27 again.

[0040] As a further optimization of this embodiment: handle grooves 19 are formed on both sides of the frame body 10, and chamfers are formed at the four corners on the outside of the frame body 10. Through the setting of the handle grooves 19, it is convenient to carry, stack and move the frame body 10.

[0041] As a further optimization of this embodiment: a buffer sponge pad 20 is embedded in the inner bottom wall of the frame body 10 below the liquid crystal display 11. Through the setting of the buffer sponge pad 20, when the liquid crystal display 11 is placed inside the frame body 10, better protection can be formed, reducing the damage to the liquid crystal display 11 easily caused by rigid contact.

[0042] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
