Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, and in particular to a measuring support for land resource management. Background Technology

[0002] Land resource management involves multiple tasks such as topographic surveying, boundary delineation, and resource investigation. As a basic tool that supports surveying instruments (such as total stations and GPS receivers), the performance of the surveying support directly affects the surveying accuracy and work efficiency.

[0003] Existing measuring supports are often complex in structure and remain bulky even when folded, making them inconvenient to carry and transport. This increases the burden on surveyors and transportation costs. Furthermore, the support legs of some supports are not well adapted to complex terrain and lack stability. They are prone to swaying or even tipping over on uneven ground or in strong winds, affecting measurement accuracy and potentially damaging measuring instruments. In response to this technical problem, this application proposes a measuring support for land resource management. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies by proposing a measuring support for land resource management. By retracting the support legs and rotating the connecting rod and sleeve, the measuring support can be stored in a smaller volume, thereby effectively reducing the burden on surveyors and improving transportation efficiency. Furthermore, through the worm gear, worm wheel and gear transmission structure, the opening angle of the two support legs can be synchronously and flexibly adjusted, enabling the measuring support to maintain a stable support state in complex terrain, thereby ensuring the accuracy of the measurement work.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A measuring bracket for land resource management includes a mounting plate. Three fixing blocks are fixedly connected to the lower end of the mounting plate. A rotating shaft is rotatably connected to the lower part of each fixing block. A connecting rod is fixedly connected to the outer wall of the rotating shaft. A rotating shaft is fixedly connected to the lower part of the connecting rod. A sleeve rod is rotatably connected to the outer wall of the rotating shaft. A snap-fit ​​assembly is provided on the upper side of the outer end of the sleeve rod. A support leg is slidably connected inside the sleeve rod. Two support feet are connected to the lower end of the support leg through an adjustment assembly.

[0007] Furthermore, the snap-fit ​​assembly includes a fixed shaft fixedly connected to the upper part of the sleeve rod, an adjusting plate rotatably connected to the outer wall of the fixed shaft, a snap-fit ​​rod fixedly connected to the upper part of the adjusting plate, a spring fixedly connected to the lower part of the adjusting plate, and the other end of the spring fixedly connected to the upper part of the sleeve rod.

[0008] Furthermore, the snap-fit ​​assembly also includes a second snap-fit ​​rod fixedly connected to the lower part of the connecting rod, and the outer wall of the second snap-fit ​​rod is slidably connected to the outer wall of the first snap-fit ​​rod.

[0009] Furthermore, a fixing clamp is fixedly connected to the upper side of both the left and right ends of the connecting rod, and an elastic ball is fixedly connected to the opposite end of the fixing clamp.

[0010] Furthermore, limiting grooves are provided on the lower sides of both the left and right ends of the sleeve rod, and the inner diameter of the limiting groove matches the outer diameter of the elastic ball.

[0011] Furthermore, the adjustment assembly includes a worm gear rotatably connected to the lower part of the support leg, a knob fixedly connected to the outer end of the worm gear, a worm wheel meshing with the outer wall of the worm gear, a rotating rod fixedly connected to the middle part of the worm wheel, the outer wall of the rotating rod rotatably connected to the lower part of the support leg, and the end of the rotating rod fixedly connected to the inside of the outer support foot.

[0012] Furthermore, a spur gear is fixedly connected to the outer wall of the rotating rod, a spur gear is meshed with the outer wall of the spur gear, a rotating rod is fixedly connected to the middle of the spur gear, the outer wall of the rotating rod is rotatably connected to the lower part of the support leg, and the end of the rotating rod is fixedly connected to the inside of the inner support foot.

[0013] Furthermore, an adjusting bolt is threaded to the lower outer end of the sleeve rod to limit the extension length of the support leg.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by retracting the support legs, rotating the connecting rod, and the sleeve rod, the measuring bracket can be folded into a smaller volume, significantly reducing the space occupied during transportation and storage, thereby effectively reducing the burden on measuring personnel and improving transportation efficiency. Furthermore, through the setting of locking rod one, locking rod two, elastic ball, and limiting groove, the connection of each component is relatively stable in both the unfolded and folded states of the bracket, preventing loosening or displacement of components during use or transportation, thus ensuring the overall stability of the bracket's performance.

[0016] 2. In this utility model, the opening angle of the two support legs can be synchronously and flexibly adjusted by rotating the knob through the worm gear, worm wheel and gear transmission structure. This allows the measuring bracket to quickly adjust the angle of the support legs on uneven ground, slopes and other complex terrains, and maintain a stable support state. This effectively avoids the impact on measurement accuracy due to the bracket shaking or tipping, ensures the accuracy of the measurement work, and also reduces the risk of damage to the measuring instrument.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a land resource management measuring bracket, including a mounting plate 1. Three fixing blocks 2 are fixedly connected to the lower end of the mounting plate 1. A rotating shaft 3 is rotatably connected to the lower part of each fixing block 2. A connecting rod 4 is fixedly connected to the outer wall of the rotating shaft 3. A rotating shaft 16 is fixedly connected to the lower part of the connecting rod 4. A sleeve rod 5 is rotatably connected to the outer wall of the rotating shaft 16. A snap-fit ​​assembly is provided on the upper side of the outer end of the sleeve rod 5. The snap-fit ​​assembly includes a fixing shaft 12 fixedly connected to the upper part of the sleeve rod 5. An adjusting plate 11 is rotatably connected to the outer wall of the fixing shaft 12. A snap rod 13 is fixedly connected to the upper part of the adjusting plate 11. The lower part of the adjusting plate 11... A spring 15 is fixedly connected, and the other end of the spring 15 is fixedly connected to the upper part of the sleeve rod 5. The snap-fit ​​assembly also includes a snap-fit ​​rod 14 fixedly connected to the lower part of the connecting rod 4. The outer wall of the snap-fit ​​rod 14 is slidably connected to the outer wall of the snap-fit ​​rod 13. Fixed clamping plates 8 are fixedly connected to the upper sides of both the left and right ends of the connecting rod 4. An elastic ball 9 is fixedly connected to the opposite end of the fixed clamping plate 8. Limiting grooves 10 are opened on the lower sides of both the left and right ends of the sleeve rod 5. The inner diameter of the limiting groove 10 matches the outer diameter of the elastic ball 9. A support leg 6 is slidably connected inside the sleeve rod 5. An adjusting bolt 17 is threadedly connected to the lower side of the outer end of the sleeve rod 5 to limit the extension length of the support leg 6.

[0025] Specifically, when the support needs to be deployed, the connecting rod 4 rotates around the pivot 3 to deploy. The pivot 3 is a damping pivot to ensure the stability of the connecting rod 4 after rotation. The sleeve rod 5 rotates around the pivot 16 to deploy. When the sleeve rod 5 is deployed to the appropriate position, the adjusting plate 11, under the elastic force of the spring 15, engages the locking rod 13 and the locking rod 14, fixing the relative position of the sleeve rod 5 and the connecting rod 4. Then, the adjusting bolt 17 is rotated to press against or release the support leg 6. When the adjusting bolt 17 presses against the support leg 6, it restricts its further extension. When the adjusting bolt 17 is released, the support leg 6 can slide within the sleeve rod 5 to achieve height adjustment. When it needs to be retracted... Press down on the lower part of the adjusting plate 11. At this time, the middle part of the adjusting plate 11 rotates around the fixed shaft 12. The adjusting plate 11 compresses the spring 15, causing the locking rod 13 and locking rod 14 on the upper part of the adjusting plate 11 to separate, thereby releasing the locking and fixing state between the sleeve rod 5 and the connecting rod 4. Then, rotate the sleeve rod 5 to fold it inward. During the folding process, when the sleeve rod 5 rotates to a specific position, the elastic ball 9 will be locked into the limiting groove 10 to ensure the stability of the sleeve rod 5 in the folded state and prevent it from shaking randomly. Finally, rotate the connecting rod 4 to close it inward around the rotating shaft 3. This completes the storage and folding operation of the entire bracket, folding the bracket into a compact form. Through the above folding method, the measuring bracket can be stored in a smaller volume, which greatly reduces the space occupied during transportation and storage, thereby effectively reducing the burden on measuring personnel, improving transportation efficiency, and also reducing the inconvenience and potential risks caused by the excessive size of the bracket during transportation.

[0026] Reference Figure 1and Figure 4 The lower end of the support leg 6 is connected to two support feet 7 via an adjustment assembly. The adjustment assembly includes a worm gear 19 rotatably connected to the lower part of the support leg 6, a knob 18 fixedly connected to the outer end of the worm gear 19, a worm wheel 20 meshing with the outer wall of the worm gear 19, a rotating rod 21 fixedly connected to the middle of the worm wheel 20, the outer wall of the rotating rod 21 rotatably connected to the lower part of the support leg 6, the end of the rotating rod 21 fixedly connected to the inside of the outer support foot 7, a spur gear 22 fixedly connected to the outer wall of the rotating rod 21, a spur gear 24 meshing with the outer wall of the spur gear 22, a rotating rod 23 fixedly connected to the middle of the spur gear 24, the outer wall of the rotating rod 23 rotatably connected to the lower part of the support leg 6, and the end of the rotating rod 23 fixedly connected to the inside of the inner support foot 7.

[0027] Specifically, rotating knob 18 causes the worm gear 19, which is fixedly connected to it, to rotate. Since the worm gear 19 meshes with the worm wheel 20, the rotation of the worm gear 19 drives the worm wheel 20 to rotate. When the worm wheel 20 rotates, it drives the rotating rod 21 to rotate. Because the end of the rotating rod 21 is fixedly connected to the inside of the outer support foot 7, the outer support foot 7 will rotate accordingly. At the same time, the spur gear 22, which is fixedly connected to the outer wall of the rotating rod 21, will also rotate with the rotating rod 21. The spur gear 22 meshes with the spur gear 24, thereby driving the spur gear 24 to rotate. When the spur gear 24 rotates, it drives the rotating rod 23 to rotate, which in turn causes the inner support foot 7 to rotate as well. By continuously rotating knob 18, the opening angle of the two support feet 7 can be adjusted synchronously and precisely to adapt to different terrain conditions, thereby ensuring the stability of the support during the measurement process and ensuring measurement accuracy.

[0028] Working principle: In use, first take the device to the location where measurement is needed. Then pull the connecting rod 4 to extend it to a suitable angle. Next, pull the sleeve rod 5 forcefully to separate the limiting groove 10 on the sleeve rod 5 from the elastic ball 9. Then rotate the sleeve rod 5 to extend it. When the sleeve rod 5 is fully extended, the locking rod 13 on the adjusting plate 11 will engage with the locking rod 14 on the connecting rod 4, ensuring the connection stability between the connecting rod 4 and the sleeve rod 5. Then, rotate the adjusting bolt 17 to adjust the extension length of the support leg 6 to adjust the height of the bracket. When encountering complex terrain, the lower side of the support leg 6 can be rotated... Knob 18 rotates the worm gear 19, which meshes with the worm wheel 20. The worm wheel 20 rotates accordingly, which in turn drives the rotating rod 21 to rotate. The outer support leg 7 connected to the rotating rod 21 begins to rotate. At the same time, the spur gear 22 on the rotating rod 21 meshes with the spur gear 24, causing the spur gear 24 to drive the rotating rod 23 to rotate. The inner support leg 7 also rotates synchronously. By observing the stability of the measuring bracket, knob 18 is continuously rotated until the two support legs 7 are adjusted to a suitable opening angle, so that the measuring bracket remains stable on the terrain. Then, subsequent measurement work can be carried out.

[0029] After the measurement is completed, turn the knob 18 in the opposite direction to bring the support legs 7 together. Then, retract the support legs 6 into the sleeve rod 5 by adjusting the bolt 17. Then, press the lower part of the adjusting plate 11. At this time, the adjusting plate 11 compresses the spring 15, and the middle part of the adjusting plate 11 rotates around the fixed shaft 12, causing the locking rod 13 and locking rod 14 on the upper part of the adjusting plate 11 to separate. Then, rotate the sleeve rod 5 to fold it inward. At this time, the elastic ball 9 is inserted into the limiting groove 10 to ensure the stability of the sleeve rod 5. Then, rotate the connecting rod 4 to bring them together, thus completing the storage of the bracket.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
