Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a display device for urban planning construction blueprints. Background Technology

[0002] In fields such as urban planning and architectural design, the presentation of construction blueprints is an indispensable part of project discussions, review reports, and public presentations. Currently, commonly used blueprint display devices are mostly simple display racks or easels, and blueprint boards are usually fixed to the display rack by means of slots, screws, or clips.

[0003] However, in situations where frequent changes to different blueprints are required, such as review meetings comparing multiple options, this traditional fixed method reveals its shortcomings. Operators need to spend a lot of time disassembling and installing, which is not only cumbersome but also reduces the smoothness and efficiency of the meeting or presentation. In addition, the height of most existing display devices is usually fixed or requires manual adjustment in stages. This design is difficult to provide the best viewing angle for audiences of different heights and viewing positions, such as sitting or standing postures, and lacks flexibility. In some formal presentation occasions, the manual adjustment process also appears unprofessional and inconvenient.

[0004] Therefore, this utility model proposes a blueprint display device for urban planning to address the shortcomings of existing technologies. Utility Model Content

[0006] This utility model provides a display device for urban planning construction blueprints, including: a base, an adjustment mechanism disposed on the base, and a mounting frame driven to rise and fall by the adjustment mechanism; and a quick-release mechanism disposed within the mounting frame.

[0007] The adjustment mechanism includes a lifting plate, a drive assembly, a double gear connected to the drive assembly, and a double rack meshing with the double gear.

[0008] Furthermore, the mounting bracket is fixed to the lifting plate, the double rack is fixedly connected to the lifting plate to drive its lifting, and the quick-release mechanism includes a locking assembly that is detachably connected to the mounting shaft of the blueprint board.

[0010] Preferably, the quick-release mechanism further includes a mounting shaft that cooperates with the locking assembly, one end of the mounting shaft is fixed with a fixing block, and a slider is slidably sleeved on the outer periphery of the fixing block.

[0011] Preferably, the buckle is used to engage with the groove formed between the fixing block and the slider in the locked state.

[0012] Preferably, the engaging assembly further includes an engaging frame and a telescopic rod, the engaging frame being fixed inside the mounting frame, and the buckle and disc spring being accommodated within the engaging frame.

[0013] Preferably, the driving component of the adjusting mechanism includes a motor, a worm gear driven by the motor, and a worm wheel meshing with the worm gear, wherein the worm wheel is coaxially and fixedly connected to the double gear.

[0014] Preferably, the adjustment mechanism further includes a support cylinder, which is fixed inside the base, and the drive assembly, double gears, and double racks are all disposed inside the support cylinder.

[0015] Preferably, the adjustment mechanism further includes a limiting shaft, which is fixed inside the support cylinder and passes through the double rack to limit the vertical movement path of the double rack.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a quick-release mechanism, allows the fixing block and slider on the installation shaft to act sequentially with the spring-driven buckle by pressing the installation shaft, realizing the quick locking and unlocking of the blueprint board.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a blueprint display device for urban planning, which aims to solve the problems of cumbersome blueprint replacement, low disassembly and assembly efficiency, and difficulty in adjusting the display height in the prior art.

[0029] like Figure 1 and Figure 2As shown, a blueprint display device for urban planning includes a base 2 and an adjustment mechanism 4 disposed on the base 2. The adjustment mechanism 4 includes a lifting plate 402 and a mounting frame 1 fixed on the lifting plate 402. The mounting frame 1 is used to install the blueprint board 301. The base 2 provides stable support for the entire device.

[0030] To solve the above-mentioned technical problems, the technical solution of this embodiment is that a construction blueprint display device for urban planning includes a quick-release mechanism 3 disposed inside the mounting frame 1, and an adjustment mechanism 4 for driving the mounting frame 1 to rise and fall.

[0031] Please refer to the following carefully. Figure 3 The quick-release mechanism 3 is used to quickly assemble and disassemble the blueprint board 301. A mounting shaft 302 is connected to the blueprint board 301. The quick-release mechanism 3 includes a locking assembly 305 detachably connected to the mounting shaft 302. The locking assembly 305 includes a locking frame 3051 fixed inside the mounting bracket 1. A latch 3053, a disc spring 3054, and a telescopic rod 3052 are provided inside the locking frame 3051. The disc spring 3054 provides an elastic restoring force for the latch 3053. One end of the telescopic rod 3052 is connected to the latch 3053. To stabilize its movement, a fixing block 303 is fixedly connected to one end of the mounting shaft 302. A slider 304 is slidably fitted on the outer periphery of the fixing block 303. When the mounting shaft 302 is inserted, the fixing block 303 pushes the latch 3053. After passing the latch 3053, the latch 3053 is reset under the action of the disc spring 3054 and locks into the groove formed between the fixing block 303 and the slider 304. When it needs to be removed, the mounting shaft 302 is pushed in again, and the slider 304 will push the latch 3053 again to unlock it.

[0032] Please refer to the following carefully. Figure 4 The internal structure of the adjustment mechanism 4 is housed in a support cylinder 401 fixed inside the base 2. The adjustment mechanism 4 includes a drive assembly 405, which includes a motor 4051. The output end of the motor 4051 is connected to a worm gear 4052. The worm gear 4052 is meshed with a worm wheel 4053. The worm wheel 4053 is coaxially and fixedly connected with a double gear 4054. The double gear 4054 is meshed with a double rack 403. The double rack 403 is fixedly connected to a lifting plate 402, thereby converting the rotational motion of the motor 4051 into the vertical lifting motion of the lifting plate 402. The adjustment mechanism 4 also includes a limiting shaft 404 fixed inside the support cylinder 401. The limiting shaft 404 passes through the double rack 403 and is used to guide and limit the vertical movement of the double rack 403 to ensure its smooth movement.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] In a preferred embodiment, in order to achieve rapid locking and releasing of the blueprint board 301, the locking assembly 305 includes a buckle 3053 and a disc spring 3054. One end of the mounting shaft 302 is fixedly connected to a fixing block 303. A slider 304 is slidably sleeved on the outer periphery of the fixing block 303. The buckle 3053 is used to engage in the groove formed between the fixing block 303 and the slider 304 in the locked state. The locking assembly 305 also includes a locking frame 3051 and a telescopic rod 3052. The locking frame 3051 is fixed inside the mounting frame 1. The buckle 3053 and the disc spring 3054 are accommodated in the locking frame 3051.

[0035] In another preferred embodiment, in order to achieve smooth lifting and lowering of the mounting frame 1, the drive assembly 405 includes a motor 4051, a worm gear 4052 driven by the motor 4051, and a worm wheel 4053 meshing with the worm gear 4052. The worm wheel 4053 is coaxially and fixedly connected to the double gear 4054. The adjustment mechanism 4 also includes a support cylinder 401, which is fixed inside the base 2. The drive assembly 405, the double gear 4054, and the double rack 403 are all disposed inside the support cylinder 401. The adjustment mechanism 4 further includes a limiting shaft 404, which is fixed inside the support cylinder 401 and passes through the double rack 403.

[0036] Working principle: The blueprint board 301 is placed at the top of the mounting bracket 1, aligning the mounting shaft 302 in the quick-release mechanism 3 with the center of the engaging frame 3051 in the engaging assembly 305. The engaging frame 3051 is fixed inside the mounting bracket 1. Then, the mounting shaft 302 is moved inside the engaging frame 3051. The fixing block 303 at the bottom of the mounting shaft 302 pushes the latch 3053 to compress the disc spring 3054. Simultaneously, the telescopic rod 3052 retracts, ensuring a smooth movement path for the latch 3053 and the disc spring 3054. After the fixing block 303 is moved past the latch 3053, the disc spring... The elastic reset pushes the buckle 3053 into the fixing block 303 and the slider 304, so that the blueprint board 301 is quickly fixed on the top of the mounting bracket 1. When the blueprint board 301 needs to be removed, the mounting shaft 302 is continuously pushed, so that the slider 304 sliding on its outer wall pushes the buckle 3053 again. When the slider 304 moves past the buckle 3053 and contacts the fixing block 303, the blueprint board 301 is lifted upward to pull the mounting shaft 302 out from the clamping bracket 3051. Finally, the blueprint board 301 can be quickly disassembled and assembled, which is convenient for replacing different city construction blueprints and improving display efficiency.

[0037] The motor 4051 is started, and its output end drives the worm gear 4052 to rotate inside the support cylinder 401. The support cylinder 401 is fixed inside the base 2, providing stable support for the entire adjustment mechanism 4. Through the meshing of the worm gear 4052 and the worm wheel 4053, the worm wheel 4053 is driven to rotate, which in turn causes the double gear 4054 fixed on the rotating shaft installed in the middle of the worm wheel 4053 to rotate. The two ends of the rotating shaft are fixed inside the support cylinder 401, which can provide power for the drive assembly 40. The rotation of the internal components provides support. The double gear 4054 and the double rack 403 can be driven to move vertically through the meshing action of the double gear 4054 and the double rack 403. The two limiting shafts 404 sliding inside the double rack 403 are fixed inside the support cylinder 401, which allows the double rack 403 to move vertically in a straight line, thereby driving the lifting plate 402 to move vertically inside the support cylinder 401, realizing the lifting of the mounting frame 1. The display height of the blueprint board 301 can be adjusted by lifting the mounting frame 1 to meet different display needs.
