Description

Technical Field

[0001] The present invention relates to the technical field of information display, and specifically to a display device for information technology development. Background Technique

[0002] Information technology is a general term for various technologies mainly used for managing and processing information. It mainly applies computer science and communication technologies to design, develop, install, and implement information systems and application software. It is also often referred to as information and communication technology, mainly including sensing technology, computer and intelligent technology, communication technology, and control technology. A display device is required during the development of information technology. However, the existing display devices are inconvenient to adjust the height and angle according to the needs of users. At the same time, a large amount of dust will accumulate on the display device during long-term use, making it inconvenient to clean. In view of this, we propose a display device for information technology development.

[0003] As disclosed in a display device for information technology development with the Chinese patent publication number CN113757526B, through a turntable rotatably connected to one side of the bottom plate, when the height of the display device needs to be adjusted during operation, the turntable can be rotated. The turntable drives the first bevel gear to rotate through a rotating rod. The first bevel gear drives the lifting screw rod to rotate through meshing with the second bevel gear. The lifting screw rod drives the lifting plate to adjust the height through a threaded tube. When the angle of the display screen needs to be adjusted, the second rotating shaft can be pulled outwards to drive the limiting gear to disengage from the limiting groove. Then, after rotating the display screen to the appropriate angle, the second rotating shaft is released, and under the action of the limiting spring, the limiting gear resets and enters the limiting groove, fixing the display screen again.

[0004] The prior art has the following problems: In the above device, the display device is independently installed on the lifting plate. Therefore, it is very easy to cause external collisions when not in use, resulting in damage. And in this device, the lifting mechanism mainly rotates through the transmission of the screw rod and the gear to complete the lifting of the lifting rod. During long-term use, the wear of the gear is likely to cause the lifting rod to be unable to rotate. In addition, this lifting mechanism lacks a positioning and fixing device, and sudden height changes may occur during use, affecting the normal operation of information technology development. Summary of the Invention

[0005] The purpose of the present invention is to provide a display device for information technology development to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A display device for information technology development, including a mounting support, on which a display device is provided. The display device includes a lifting unit and a display unit. The display unit is installed on the lifting unit, and the lifting unit is installed on the top of the mounting support; The lifting unit includes a vertical rod, on which a lifting sleeve is provided. The outer wall of the lifting sleeve is provided with a connecting block, and an installation groove is opened in the connecting block. At the installation groove, a first connecting shaft is provided. At both ends of the first connecting shaft, connecting rods are symmetrically distributed. The other end of the connecting rod is provided with a second connecting shaft, which is located in an arc-shaped fixed block. The arc-shaped fixed block is located on a slider, and the slider is located at a chute in a sliding seat.

[0007] In the present invention, the slider slides in the chute of the sliding seat. As shown in the attached drawing, when the two sliders slide towards each other, the arc-shaped fixed block provided on the top of the slider moves accordingly, pulling the connecting rod, so that the lifting sleeve rises and falls on the vertical rod, and finally the lifting of the display device is achieved, thereby realizing different heights of the display of the display device and improving the effect and efficiency of information technology development.

[0008] According to the above technical solution, the vertical rod is vertically and fixedly installed on the top of the mounting support through fasteners.

The first connecting shaft is fixedly installed in the connecting block through the installation groove. The first connecting shaft is fixedly connected to the connecting rod, and the connecting rod is fixedly connected to the second connecting shaft.

[0009] According to the above technical solution, the second connecting shaft is fixedly installed in the arc-shaped fixed block. The arc-shaped fixed block is welded to the top of the slider. The slider is slidably connected to the sliding seat through the chute, and the sliding seat is fixedly installed on the mounting support.

[0010] According to the above technical solution, in order to fix the slider and enable the sliding of the slider to correspond to different heights of the lifting of the lifting sleeve, the present invention adopts the following technical solution. A sliding frame is provided on one side of the sliding seat. An engaging chute is opened in the sliding frame. An engaging sliding plate is provided in the engaging chute. A connecting arm is provided on the engaging sliding plate, and a telescopic rod is provided on the connecting arm. A positioning and installation hole is opened on the sliding frame. The engaging sliding plate is fixedly connected to the slider through a fixing rod.

[0011] In the process of fixing the lifting unit in the present invention, the telescopic rod on the connecting arm can correspond to different positioning and installation holes, that is, the fixing of different positions is completed. After the telescopic rod is inserted into the positioning and installation hole, it represents the fixing of the slider, so that the display device will not suddenly move in height during use.

[0012] According to the above technical solution, the sliding frame is vertically and fixedly welded to the mounting support. The sliding frame is slidably connected to the fitting slide plate. The connecting arm is welded to the fitting slide plate. The telescopic rod is fixedly connected to the connecting arm. The telescopic rod is movably connected to the sliding frame through the positioning insertion hole.

[0013] According to the above technical solution, the display unit includes a support rod. A placement plate is provided at the top of the support rod. The top of the vertical rod penetrates through the placement plate to the upper side of the placement plate. The other end of the support rod is located on the lifting sleeve. A placement groove is formed in the middle of the placement plate. A storage frame is provided in the placement groove. Connecting plates are symmetrically distributed at the left and right ends of the storage frame.

[0014] In the present invention, the placement plate is penetrated by the vertical rod, which means that the placement plate is limited by the support rod. During the process of the support rod moving along with the lifting sleeve, the placement plate realizes lifting. And by providing a placement groove and a storage frame in the placement plate, the display device can be stored in the placement groove and the storage frame when not in use, avoiding accidental touch and collision.

[0015] According to the above technical solution, three fixed blocks are arranged at equal intervals at one end inside the storage frame. Slide rods are respectively provided on the three fixed blocks. A display moving block is provided on the slide rod. A display connecting block is provided at the end of the display moving block away from the fixed block. A display main body is provided at the other end of the display connecting block. A sliding seat is provided on one side of the display main body. A caliper plate is provided inside the sliding seat. A first gear is provided above the caliper plate. The first gear is located on a display linkage shaft. A folding connecting rod is provided on the display linkage shaft.

[0016] According to the above technical solution, the storage frame is welded to the three fixed blocks respectively. The fixed block is fixedly connected to the slide rod. The display connecting block is slidably connected to the slide rod. The display connecting block is welded to the display moving block. The display connecting block is connected to the display main body through the folding connecting rod. The display main body is fixedly connected to the sliding seat. The caliper plate is movably installed inside the sliding seat. The caliper plate meshes with the first gear. The first gear is key-connected to the display linkage shaft. And the folding connecting rod is sleeved on the display linkage shaft.

[0017] The technical solution adopted by the present invention for the folding and unfolding of the display main body is as follows: by moving the caliper plate and meshing it with the first gear, the first gear rotates, and then the display linkage shaft rotates. Therefore, the folding connecting rod rotates. Because of the connection relationship between the folding connecting rod and the display main body, the display main body rotates and folds. However, the difficulty in the actual implementation process is how to make the display main body rotate to the vertical state automatically after being pushed out of the storage frame, and rotate to the flat placement state automatically when the display main body is recovered and then be protected by the placement groove.

[0018] According to the above technical solution, to solve the above-mentioned difficulties, the present invention is provided with the following components to complete. A second gear is provided on the caliper plate. The second gear is located on a display connecting rod. The other end of the display connecting rod is provided with a connecting moving block. The connecting moving block is located on a slide rail. One end of the slide rail is provided with an inclined portion.

[0019] According to the above technical solution, the second gear is clamped with the caliper plate, and the second gear is in transmission connection with the display connecting rod. The display connecting rod is movably connected with the connecting moving block. The connecting moving block is slidably connected with the slide rail. The slide rail is fixedly installed on the storage frame.

[0020] Among them, due to the clamping of the second gear with the caliper plate and the meshing state of the second gear with the caliper plate, when the display moving block moves to one end, the second gear, the display connecting rod and the connecting moving block all move accordingly. When the connecting moving block moves to the inclined portion, due to the inclined design of the inclined portion, the connecting moving block slides obliquely. At this time, the display connecting rod rotates at an angle, and then the second gear is driven by the display connecting rod to rotate. Then the caliper plate moves horizontally in the sliding seat, and then the rotation of the first gear is completed. Therefore, it is realized that the display body automatically rotates to a vertical state after moving to one end of the storage frame for the user to view, and during the recycling process, it automatically completes horizontal placement without manual control, saving time and improving the development efficiency.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In the present invention, by setting the movement of the fitting slide plate in the fitting chute in the lifting unit and the telescopic rod can correspond to different positioning and insertion holes, the fixation at different positions is completed, so that the display device will not suddenly move in height during use, improving the stability of the overall device.

[0022] 2. In the present invention, by setting the two sliders in the lifting unit to slide towards each other, the lifting sleeve is lifted and lowered on the vertical rod, and finally the lifting of the display device is achieved, so as to realize different heights of the display device display, improving the effect and efficiency of information technology development.

[0023] 3. In the present invention, by setting the movement of the caliper plate in the display unit, the first gear rotates, and then the folding link rotates. Due to the connection relationship between the folding link and the display body, the display body rotates and folds, which is convenient for the user to observe and can be stored in the storage frame when not in use, avoiding damage to the display body caused by collision.

[0024] 4. In the present invention, by arranging the connection moving block in the display unit to move to the inclined part, and making the connection moving block slide obliquely through the inclined design of the inclined part, the display body can automatically rotate to a vertical state after moving to one end of the storage box, so as to be convenient for the user to view. And during the recycling process, it can automatically complete the horizontal placement without manual control, saving time and improving the development efficiency.

The slider 208 is slidably connected to the sliding seat 209 through the chute. The sliding seat 209 is fixedly installed on the mounting support 1. Embodiment 2:

[0033] Based on the first embodiment: In order to fix the slider 208 and enable the sliding of the slider 208 to correspond to different heights of the lifting of the lifting sleeve 202, the present invention adopts the following technical solution.

[0036] Based on the first and second embodiments: The display unit includes a support rod 301. A placement plate 302 is provided at the top of the support rod 301. And the top of the vertical rod 201 penetrates through the placement plate 302 to the upper side of the placement plate 302. The other end of the support rod 301 is located on the lifting sleeve 202.

Connecting plates 305 are symmetrically distributed at the left and right ends of the storage frame 304.

[0037] In the present invention, the placement plate 302 is penetrated by the vertical rod 201, which means that the placement plate 302 is limited by the support rod 301. During the process of the support rod 301 moving with the lifting sleeve 202, the placement plate 302 realizes lifting. And a placement groove 303 and a storage frame 304 are provided in the placement plate 302, so that the display device can be stored in the placement groove 303 and the storage frame 304 when not in use, avoiding being accidentally touched and collided.

[0038] Three groups of fixed blocks 306 are arranged equidistantly at one end of the storage frame 304, and sliding rods 307 are respectively provided on the three fixed blocks 306, and display moving blocks 308 are provided on the sliding rods 307. A display connecting block 309 is provided at one end of the display moving block 308 away from the fixed block 306, and a display main body 310 is provided at the other end of the display connecting block 309. A sliding seat 311 is provided on one side of the display main body 310, and a caliper plate 312 is provided in the sliding seat 311. A number one gear 313 is provided above the caliper plate 312, and the number one gear 313 is located on a display linkage shaft 314, and a folding connecting rod 315 is provided on the display linkage shaft 314.

[0039] The storage frame 304 is welded to three fixed blocks 306 respectively, and the fixed blocks 306 are fixedly connected to the sliding rod 307, the display moving block 308 is connected to the sliding rod 307, the display connecting block 309 is welded to the display moving block 308, the display connecting block 309 is connected to the display body 310 through the folding connecting rod 315, the display body 310 is fixedly connected to the sliding seat 311, the caliper plate 312 is movably installed in the sliding seat 311, the caliper plate 312 is meshed with the number one gear 313, the number one gear 313 is key-connected to the display linkage shaft 314, and the folding connecting rod 315 is sleeved on the display linkage shaft 314.

[0040] The technical solution adopted by the present invention for the folding and expansion of the display body 310 is that the caliper plate 312 moves and meshes with the No. 1 gear 313, so that the No. 1 gear 313 rotates, and then the display linkage shaft 314 rotates, so that the folding link 315 rotates. Because the folding link 315 is connected to the display body 310, the display body 310 rotates and folds. However, the difficulty in the actual implementation process lies in how to push the display body 310 out of the storage frame 304, so that the display body 310 rotates to a vertical state by itself, and when the display body 310 is recovered, it rotates autonomously to a flat placement state and is then protected by the placement slot 303. Embodiment 4:

[0041] On the basis of Example 3: In order to solve the difficulties mentioned above, the present invention is completed by setting up the following components: a second gear 320 is provided on the caliper plate 312, and the second gear 320 is located on a display connecting rod 316.

[0043] Among them, due to the engagement between the second gear 320 and the caliper plate 312, and the second gear 320 and the caliper plate 312 are in a meshing state. Therefore, after showing that the moving block 308 moves to one end, the second gear 320, the display connecting rod 316 and the connecting moving block 317 all move accordingly. When the connecting moving block 317 moves to the inclined part 319, due to the inclined design of the inclined part 319, the connecting moving block 317 slides obliquely. At this time, the display connecting rod 316 rotates at an angle, and then the second gear 320 is driven by the display connecting rod 316 to rotate. Then the caliper plate 312 moves horizontally in the sliding seat 311, and then the rotation of the first gear 313 is completed. Therefore, it is realized that the display body 310 automatically rotates to a vertical state after moving to one end of the storage box 304, so as to be convenient for the user to view, and automatically completes the horizontal placement during the recycling process, without manual control, saving time and improving the development efficiency.
