Description

Technical Field

[0001] This application relates to the technical field of urban and rural planning, and more particularly to a portable survey tool for urban and rural planning. Background Technology

[0002] In field surveys for urban and rural planning, land surveying, and municipal engineering, technicians often need to carry a variety of surveying tools (such as rangefinders, inclinometers, compasses, laser levels, etc.) to the site for data collection.

[0003] Traditional methods typically employ modular toolkits, storing various instruments separately and requiring individual hand-held operation. This presents several problems: First, the equipment is scattered, bulky, and heavy, making it extremely inconvenient to carry over long distances in the field. Second, each time a measuring tool is changed, it must be removed from the bag, installed, and disassembled after use, a cumbersome and time-consuming process that severely impacts work efficiency. Third, when measuring on soft or uneven ground, the lack of dedicated support structures means that simple tripods are insufficient to guarantee instrument stability and measurement accuracy. This is especially true in windy conditions or when movement by people causes significant data errors. Adding support structures would increase the complexity of the measuring tools, making them even less portable. Summary of the Invention

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The following description, in conjunction with the accompanying drawings, describes a portable survey tool for urban and rural planning according to embodiments of this application.

[0022] like Figures 1-4 As shown in the embodiment of this application, a portable survey tool for urban and rural planning includes a storage box 10, a pull rod 20, a stabilizing component 30, and a storage component 40. The pull rod 20 is slidably disposed on one side of the storage box 10. The stabilizing component 30 includes two support rods 301 mounted on the storage box 10. Lifting plates 302 are slidably disposed on the surfaces of both support rods 301. Positioning pins 303 are slidably disposed on both lifting plates 302. Multiple snap-fit ​​grooves 304 are provided on both support rods 301. A first connecting rod 305 and a second connecting rod 306 are provided on both sides of the two lifting plates 302. A caster wheel 307 is provided at one end of each of the first connecting rod 305 and the second connecting rod 306. An assist mechanism 308 is provided on the two lifting plates 302 to increase the stability of the support rods 301 on the storage box 10. The storage component 40 is disposed on the storage box 10 and is used to store the survey tool.

[0023] It should be noted that the pull rod 20 adopts existing technology, and its principle is the same as that of the pull rod on the combination lock box. The length can be adjusted as needed, and it can be retracted. In the initial state, the caster wheel 307 is in contact with the ground, and the movement of the caster wheel 307 drives the movement of the storage box 10.

[0024] In one embodiment of this application, such as Figure 2 As shown, the assist mechanism 308 includes a transmission rod 3081 fixed to the first connecting rod 305; a gear 3082 is fixedly installed at one end of the transmission rod 3081; a gear 3083 is fixedly installed at one end of the second connecting rod 306; positioning rods 3084 are slidably arranged within the two first connecting rods 305 and the two second connecting rods 306; a push spring 3085 is fixedly installed at one end of each of the multiple positioning rods 3084; a pull rope 3086 is fixedly installed at one end of each of the multiple positioning rods 3084; positioning grooves 3087 are provided on each of the multiple casters 307; and a U-shaped rod 3088 is fixedly installed on the surface of the transmission rod 3081.

[0025] It should be noted that a positioning element is provided on the first connecting rod 305. The positioning element positions the first connecting rod 305 before and after rotation to ensure the relative stability of the first connecting rod 305. When the first connecting rod 305 needs to be rotated, the positioning of the first connecting rod 305 needs to be released. The positioning element can be a threaded rod or other components that can achieve the positioning of the first connecting rod 305.

[0026] In one embodiment of this application, such as Figure 2 As shown, the two ends of the pull rope 3086 are respectively connected to the positioning rods 3084 on the first connecting rod 305 and the second connecting rod 306, and the middle part of the pull rope 3086 is located outside the transmission rod 3081. The middle part of the pull rope 3086 is fixedly connected to the U-shaped rod 3088.

[0027] It should be noted that the pull rope 3086 slides within the moving plate 403, with only a portion connected to the U-shaped rod 3088, so that the pull rope 3086 can be pulled when the U-shaped rod 3088 rotates.

[0028] It should be noted that in the initial state, that is, when the first connecting rod 305 and the second connecting rod 306 have not rotated, the caster wheel 307 is in a vertical state. At this time, the pull rope 3086 is pulled by the U-shaped rod 3088, which in turn causes the positioning rod 3084 to no longer be in the positioning groove 3087. After the first connecting rod 305 and the second connecting rod 306 rotate, the U-shaped rod 3088 will no longer pull the pull rope 3086. The push spring 3085 pushes the positioning rod 3084 into the positioning groove 3087, thus locking the caster wheel 307. If there is a misalignment between the positioning rod 3084 and the positioning groove 3087, the caster wheel 307 needs to be rotated manually.

[0029] In one embodiment of this application, such as Figure 2As shown, the pull rope 3086 is slidably disposed within the first connecting rod 305, the second connecting rod 306, and the transmission rod 3081, and both the positioning groove 3087 and the positioning rod 3084 are square.

[0030] In one embodiment of this application, such as Figure 2 As shown, the gear 3082 is located inside the gear disk 3083, and the gear 3082 meshes with the gear disk 3083. The gear disk 3083 is rotatably connected to the lifting plate 302.

[0031] In one embodiment of this application, such as Figure 2 As shown, both support rods 301 are provided with storage slots, and swing rods are rotatably installed in both storage slots.

[0032] It should be noted that the swing arm can drive the support rod 301 to swing back and forth when rotating. After the caster wheel 307 contacts the ground, it can swing to drive the caster wheel 307 to swing, thereby improving the tightness between the caster wheel 307 and the ground and optimizing the support effect of the caster wheel 307.

[0033] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the storage assembly 40 includes a rotating disk 401 rotatably disposed within the storage box 10; the rotating disk 401 has multiple moving slots 402; a moving plate 403 is slidably disposed on one side of each of the multiple moving slots 402; a clamping member 404 is fixedly installed on each of the multiple moving plates 403; a pushing rod 405 is slidably disposed on the storage box 10; a locking rod 406 is fixedly installed on each of the multiple moving plates 403; a rotating slot 407 is disposed inside the storage box 10; a locking slot 408 is disposed inside the storage box 10; and a buffer mechanism 409 is disposed on the rotating disk 401.

[0034] It should be noted that an opening is provided on the top of the storage box 10, and a removable sealing plate is provided on the opening. The sealing plate can be removed during use and installed after use. The opening serves two purposes: firstly, it allows the measuring components inside the storage box 10 to be moved out from the opening; secondly, it allows the rotating disk 401 inside the storage box 10 to be rotated through the opening, thereby adjusting the position of different measuring components on the rotating disk 401 to achieve the purpose of selecting different measuring components for measurement. Furthermore, the plate on the side of the storage box 10 near the push rod 405 is detachable, which facilitates the installation or removal of the measuring components.

[0035] In one embodiment of this application, such as Figure 3 and Figure 4As shown, the rotating groove 407 is circular, and the rotating groove 407 is connected to the locking groove 408. One end of the locking rod 406 is located in the locking groove 408.

[0036] It should be noted that after the push rod 405 pushes the moving plate 403, there is a locking plate that can slide laterally below the push rod 405. The locking plate can be moved to the bottom of the push rod 405 to complete the positioning of the push rod 405 after it has been moved.

[0037] In one embodiment of this application, such as Figure 4 As shown, the buffer mechanism 409 includes a guide groove 4091 installed in the main body 10 of the storage box; a guide block 4092 is fixedly installed on the side of the rotating disk 401 near the guide groove 4091; and a buffer spring 4093 is fixedly installed on the surface of the rotating disk 401 and around the guide block 4092.

[0038] It should be noted that the buffer spring 4093 is a damping spring.

[0039] In one embodiment of this application, such as Figure 4 As shown, both the guide groove 4091 and the guide block 4092 are frustoconical. The guide block 4092 is movably disposed within the guide groove 4091. One end of each of the multiple buffer springs 4093 is fixedly connected to the inner wall of the storage box body 10.

[0040] Specifically, in actual use, when it is necessary to go out for planning and measurement, by pulling the lever 20, the caster wheel 307 moves the storage box 10. When the storage box 10 moves to the measurement position, by pulling the positioning pin 303, the positioning pin 303 is no longer engaged with the locking groove 304. Then the lifting plate 302 is moved upward, which in turn moves the caster wheel 307 upward, so that the support rod 301 contacts the ground. Then the first connecting rod 305 is rotated, which drives the transmission rod 3081 to rotate. The rotation of the transmission rod 3081 will drive the gear 3082 to rotate. Since the gear 3082 meshes with the gear disk 3083, when the gear 3082 rotates, it drives the gear disk 3083 to rotate in the opposite direction, which in turn drives the second connecting rod 306 to rotate in the opposite direction. The caster wheel 307 on the first connecting rod 305 and the second connecting rod 306 are staggered on both sides of the support rod 301. After rotation, it is positioned by the positioning component. Furthermore, as the transmission rod 3081 rotates, it will cause the U-shaped rod 3088 to stop pulling the pull rope 3086. Then, the push spring 3085 pushes the positioning rod 3084 into the positioning groove 3087 to complete the positioning of the caster wheel 307, so that the caster wheel 307 is in a horizontal state. Then, by inserting the support rod 301 into the soil, after insertion, the moving lifting plate 302 drives the caster wheel 307 to move, so that the caster wheel 307 contacts the ground. Then, the positioning pin 303 is inserted into the snap-fit ​​groove 304, so that the caster wheel 307 supports the support rod 301. Then, by rotating the rotating disk 401, the rotating disk 401 drives the different measuring components installed on the clamping member 404 to rotate, and the measuring component to be used is rotated to the top of the rotating disk 401. Then, the push rod 405 is pushed upward, and the push rod 405 pushes the moving plate 403 to move, thereby moving the moving plate 403 to the outside of the storage box 10. At the same time as the moving plate 403 moves, it will drive the locking rod 406 to move, so that the locking rod 406 enters the locking groove 408 from the rotating groove 407, completing the positioning of the rotating disk 401. Then, the planned data can be measured by the measuring component. When not in use or when the storage box 10 is moved, if there is any shaking or bumping, the swinging force will cause the rotating disk 401 to move in any direction, which in turn will cause the guide block 4092 to move in any direction. When the guide block 4092 moves, it is restricted by the guide groove 4091, so that the swinging force around the guide block 4092 is guided into a back-and-forth force. Then, the installed buffer spring 4093 is used to resist the back-and-forth swinging force, thereby achieving the protection of the measuring components on the rotating disk 401.

[0041] In summary, the portable survey tool for urban and rural planning in this application embodiment, through its pull rod and caster wheel design, allows for easy towing of the entire machine, facilitating its transport to the work site. Upon arrival, the lifting mechanism and gear-disc linkage structure enable the support rod to be quickly inserted into the ground, and the casters on both sides to automatically unfold and lock horizontally, forming a stable multi-point support, significantly improving the anti-interference capability and stability of the measurement platform. The device has a built-in rotating disk and multiple clamping positions, allowing for the pre-installation of different measurement components. Tool switching and precise locking can be completed simply by rotating the rotating disk and pushing the positioning rod, making operation simple and efficient. At the same time, during transportation, the vibration damping mechanism composed of guide grooves and buffer springs effectively absorbs the impact of bumps, protecting precision instruments. The overall design significantly improves the efficiency, accuracy, and equipment safety of field planning surveys.
