Description

Technical Field

[0001] This utility model relates to the field of simulation sand table technology, and more specifically to a simulation sand table for urban and rural planning layout. Background Technology

[0002] Urban and rural planning refers to the comprehensive deployment of land use, spatial layout, and various construction projects in urban and rural areas within a certain period, aiming to leave sufficient space for future urban and rural development. This process involves not only the rational allocation of land but also comprehensive consideration of urban and rural ecological environment, socio-economic structure, and other aspects. When carrying out urban and rural planning, it is necessary to use a simulation sand table to intuitively display the layout to people.

[0003] A search revealed an existing patent (publication number: CN217181722U) that discloses a simulated sand table for urban and rural planning layout. During use, observers typically need to walk around the sand table to find a suitable angle for observation, which can easily cause fatigue and negatively impact the viewing experience. This invention utilizes a rotating component, allowing the observer to rotate the display compartment at any angle from a designated location by rotating a rotating plate. This replaces the need for walking back and forth to observe the sand table. Furthermore, a buffer component provides some cushioning and shock absorption for the rotating display compartment, making it easier for the viewer to operate and improving the viewing experience. However, the inventors discovered the following problems with the existing technology during the development of this invention: While the aforementioned simulated sand table offers the advantage of rotation to enhance the viewing experience, the display compartment is fixedly installed to the rotating plate. When installing the model layout on the surface of the display compartment, the base obstructs the view, requiring the user to lean forward to perform the model installation operation, which is difficult and affects the quality of the model production.

[0004] In view of this, this utility model proposes a simulation sand table for urban and rural planning layout to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a simulation sand table for urban and rural planning layout to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a simulation sand table for urban and rural planning layout, including a fixed base, the fixed base being ring-shaped, a bearing plate being rotatably connected to the inner wall of the fixed base, a rotation drive component being provided between the fixed base and the bearing plate, a display plate being provided above the bearing plate, a display cavity being reserved in the inner top of the display plate, the display cavity being filled with sand, the display plate being movably installed with the bearing plate, a gripping groove being provided on the side of the display plate, and a positioning component being provided between the bearing plate and the display plate;

[0007] The positioning component includes a support foot fixedly installed at the bottom of the display plate. A slot is provided on the upper surface of the support plate. The support foot is inserted into the slot. An anti-detachment block is fixedly installed on the surface of the support foot. A locking pin is slidably connected to the inner wall of the slot. The locking pin is engaged with the inclined block. A clamping spring is provided inside the slot to drive the locking pin and the anti-detachment block to lock together.

[0008] Furthermore, a positioning pin is vertically inserted into the surface of the locking pin, and a positioning hole is opened on the inner bottom wall of the slot away from the support foot. The positioning pin and the positioning hole are positioned correspondingly, and when the positioning pin is inserted into the positioning hole, the locking pin and the anti-disengagement block move away from each other.

[0009] As a further description of the above technical solution: by setting positioning pins and positioning holes, when it is necessary to separate the display plate from the carrier plate, the positioning pins can be inserted into the positioning holes in sequence to cancel the clamping effect of the locking pins and anti-detachment blocks, thereby making it easy to remove the support legs from the slot and complete the separation operation between the display plate and the carrier plate.

[0010] Furthermore, the rotary drive assembly includes a worm gear ring fixedly mounted on the outer ring surface of the bearing plate, a drive motor fixedly mounted on the outer wall of the fixed base, and a worm fixedly mounted on the surface of the drive motor's conveying shaft, the worm meshing with the worm gear ring.

[0011] As a further description of the above technical solution: by setting up a rotary drive component, the drive motor drives the worm gear to rotate. Based on the meshing of the worm gear and the worm wheel ring, the effect of driving the support plate to rotate can be achieved, thereby driving the display plate to rotate and adjusting the viewing angle.

[0012] Furthermore, a connecting plate is fixedly installed on the inner wall of the fixed base, an avoidance hole is reserved at the center of the bearing plate, a hydraulic push rod is fixedly installed on the inner wall of the connecting plate, the telescopic end of the hydraulic push rod passes through the inside of the avoidance hole and is fixedly installed with a top seat, and a top hole for inserting the top seat is opened at the bottom of the display plate.

[0013] As a further description of the above technical solution: when it is necessary to separate the display tray from the support plate, the locking effect of the locking pin and the anti-detachment block is canceled in advance by using the positioning pin. Then, by controlling the extension of the hydraulic push rod, the top seat is raised and inserted into the top hole, which can push the display tray upward, so that the support leg is dislodged from the slot, thus facilitating the separation of the display tray.

[0014] Furthermore, a limiting slide rod is fixedly installed at the bottom end of the top seat, and the limiting slide rod is slidably connected to the surface of the connecting plate.

[0015] As a further description of the above technical solution: by setting a limit slide bar, the movement path of the top seat can be restricted, ensuring the stability of the top seat movement, and achieving the effect of anti-torsion protection for the telescopic end of the hydraulic jack.

[0016] Furthermore, the bottom of the display plate has an arc-shaped toothed groove arranged in a circular array, and a telescopic sleeve is fixedly installed on the surface of the top seat. A vibration rod is slidably connected to the top of the telescopic sleeve, and a support spring for driving the vibration rod to move upward is fixedly installed on the inner bottom wall of the telescopic sleeve. The position of the vibration rod corresponds to that of the arc-shaped toothed groove.

[0017] As a further description of the above technical solution: while maintaining the locking effect of the locking pin and the anti-detachment block, the extension of the hydraulic push rod is slightly controlled so that the vibrating rod contacts the arc-shaped tooth groove. Under this premise, the display plate is driven to rotate, and the elastic force of the support spring drives the vibrating rod to strike the inner wall of the arc-shaped tooth groove, which can vibrate the display plate, thereby facilitating the crushing and leveling of the sand inside the display plate, and providing convenience for the subsequent use of the display plate for model placement.

[0018] Furthermore, a control panel is fixedly mounted on the surface of the mounting base, and the control panel is electrically connected to an external power source via wires.

[0019] Furthermore, the lower surface of the fixed base is provided with a plurality of support rollers arranged in a circumferential array, and each of the support rollers is provided with a brake pad.

[0020] As a further description of the above technical solution: by setting up support rollers, it is convenient to move the entire sand table and adjust the display position.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] 1. Compared with existing technologies, this urban and rural planning layout simulation sand table allows for model display within a display cavity on the display panel. The rotation of the support plate enables the display panel to rotate, facilitating adjustments to the viewing angle and enhancing the viewing experience. Furthermore, by incorporating positioning components, the legs are inserted into slots, and spring-driven locking pins and anti-detachment blocks secure the display panel to the support plate. Before display, when model design and installation are required on the display panel surface, the display panel can be separated from the support plate and moved to an external location, avoiding obstruction from the fixed base, reducing the difficulty of model assembly, and thus improving the quality of model production.

[0023] 2. Compared with existing technologies, this urban and rural planning layout simulation sand table, by setting positioning pins and positioning holes, allows the positioning pins to be inserted into the positioning holes in sequence when it is necessary to separate the display plate from the support plate, eliminating the clamping effect of the locking pins and anti-detachment blocks, thus facilitating the removal of the support legs from the slots and completing the separation operation between the display plate and the support plate; by setting a rotation drive component, the drive motor drives the worm gear to rotate, and based on the meshing of the worm gear and worm wheel ring, it can achieve the effect of driving the support plate to rotate, thereby driving the display plate to rotate and adjusting the viewing angle.

[0024] 3. Compared with existing technologies, this urban and rural planning layout simulation sand table, when it is necessary to separate the display tray from the support plate, pre-emptively uses positioning pins to eliminate the clamping effect of the locking pins and anti-detachment blocks. Then, by controlling the extension of the hydraulic jack, the top seat is raised and inserted into the top hole, which can push the display tray upward, allowing the support legs to disengage from the slots, facilitating the separation of the display tray. By setting a limit slide bar, the movement path of the top seat can be restricted, ensuring the stability of the top seat's movement and achieving the effect of anti-torsion protection for the extension end of the hydraulic jack. While maintaining the clamping effect of the locking pins and anti-detachment blocks, slightly controlling the extension of the hydraulic jack allows the vibrating rod to contact the arc-shaped toothed groove. Under this premise, the display tray is driven to rotate, and the elasticity of the support spring drives the vibrating rod to strike the inner wall of the arc-shaped toothed groove, which can vibrate the display tray, thereby facilitating the crushing and leveling of the sand inside the display tray, providing convenience for the subsequent use of the display tray for model layout.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The urban and rural planning layout simulation sand table involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Reference Figures 1 to 5 This utility model provides a simulation sand table for urban and rural planning layout, including a fixed base 1, which is ring-shaped. A control panel 21 is fixedly installed on the surface of the fixed base 1, and the control panel 21 is electrically connected to an external power source through wires.

[0033] The lower surface of the fixed base 1 is provided with a number of support rollers 22 arranged in a circular array, and each of the support rollers 22 is provided with a brake pad.

[0034] By setting up support rollers 22, it is easy to move the entire sand table and adjust the display position.

[0035] The inner wall of the fixed base 1 is rotatably connected to the support plate 2. A rotation drive assembly is provided between the fixed base 1 and the support plate 2. A display plate 3 is provided above the support plate 2. A display cavity is reserved in the inner top of the display plate 3. The display cavity is filled with sand. The model is designed and built inside the display cavity, and the sand is used to support and shape the model.

[0036] The rotary drive assembly includes a worm gear ring 9 fixedly mounted on the outer ring surface of the bearing plate 2, a drive motor 10 fixedly mounted on the outer wall of the fixed base 1, and a worm 11 fixedly mounted on the surface of the conveying shaft of the drive motor 10, which meshes with the worm gear ring 9.

[0037] By setting up a rotary drive component, the drive motor 10 drives the worm gear 11 to rotate. Based on the meshing of the worm gear 11 with the worm wheel ring 9, the effect of driving the bearing plate 2 to rotate can be achieved, thereby driving the display plate 3 to rotate, adjusting the viewing angle and improving the viewing experience.

[0038] The display tray 3 and the support plate 2 are movably installed. The side of the display tray 3 is provided with a gripping groove 24, and a positioning component is provided between the support plate 2 and the display tray 3.

[0039] The positioning component includes a support leg 4 fixedly installed at the bottom of the display plate 3. A slot is provided on the upper surface of the support plate 2. The support leg 4 is inserted into the slot. An anti-detachment block 5 is fixedly installed on the surface of the support leg 4. A locking pin 6 is slidably connected to the inner wall of the slot. The locking pin 6 is engaged with the inclined block. A clamping spring 23 is provided inside the slot to drive the locking pin 6 and the anti-detachment block 5 to engage.

[0040] It is worth noting that by setting up a positioning component, inserting the support leg 4 into the slot, and using the clamping spring 23 to drive the locking pin 6 and the anti-detachment block 5 to lock together, the purpose of positioning the display plate 3 and the support plate 2 can be achieved. When the model needs to be designed and installed on the surface of the display plate 3 before the display, the display plate 3 and the support plate 2 can be separated and moved to an external position, avoiding the fixed seat 1 from causing obstruction, reducing the difficulty of model building, and thus improving the quality of model making.

[0041] A positioning pin 7 is vertically inserted into the surface of the locking pin 6. A positioning hole 8 is opened on the inner bottom wall of the slot away from the support foot 4. The positioning pin 7 and the positioning hole 8 are positioned correspondingly. When the positioning pin 7 is inserted into the positioning hole 8, the locking pin 6 and the anti-disengagement block 5 move away from each other.

[0042] It is worth noting that by setting the positioning pin 7 and positioning hole 8, when it is necessary to separate the display plate 3 from the carrier plate 2, the positioning pin 7 can be inserted into the positioning hole 8 in sequence to cancel the clamping effect of the locking pin 6 and the anti-detachment block 5, thereby making it easy to remove the support leg 4 from the slot and complete the separation operation between the display plate 3 and the carrier plate 2.

[0043] A connecting plate 12 is fixedly installed on the inner wall of the fixed base 1. An avoidance hole is reserved at the center of the bearing plate 2. A hydraulic push rod 13 is fixedly installed on the inner wall of the connecting plate 12. The telescopic end of the hydraulic push rod 13 passes through the avoidance hole and is fixedly installed with a top seat 14. A top hole 15 for the top seat 14 to be inserted is opened at the bottom of the display plate 3.

[0044] It is worth noting that when it is necessary to separate the display tray 3 from the support plate 2, the locking effect of the locking pin 6 and the anti-detachment block 5 is canceled in advance by using the positioning pin 7. Then, by controlling the extension of the hydraulic push rod 13, the top seat 14 is raised and inserted into the top hole 15, which can push the display tray 3 upward, so that the support leg 4 is dislodged from the slot, which facilitates the separation of the display tray 3.

[0045] A limiting slide rod 16 is fixedly installed at the bottom of the top seat 14, and the limiting slide rod 16 is slidably connected to the surface of the connecting plate 12.

[0046] Furthermore, by setting the limiting slide bar 16, the movement path of the top seat 14 can be restricted, ensuring the stability of the movement of the top seat 14, and achieving the effect of anti-torsion protection for the telescopic end of the hydraulic push rod 13.

[0047] The bottom of the display plate 3 has an arc-shaped toothed groove 17 arranged in a circular array. A telescopic sleeve 18 is fixedly installed on the surface of the top seat 14. A vibration rod 19 is slidably connected to the top of the telescopic sleeve 18. A support spring 20 for driving the vibration rod 19 to move upward is fixedly installed on the inner bottom wall of the telescopic sleeve 18. The position of the vibration rod 19 corresponds to that of the arc-shaped toothed groove 17.

[0048] It is worth noting that after the display model inside the display tray 3 is removed, for the display tray 3 which only contains sand, while keeping the locking pin 6 and the anti-detachment block 5 locked, the hydraulic jack 13 is slightly extended so that the vibrating rod 19 contacts the arc-shaped toothed groove 17. Under this premise, the display tray 3 is driven to rotate, and the elasticity of the support spring 20 drives the vibrating rod 19 to strike the inner wall of the arc-shaped toothed groove 17, which can vibrate the display tray 3, thereby facilitating the breaking and leveling of the sand inside the display tray 3, and providing convenience for the subsequent use of the display tray 3 for model placement.

[0049] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
