Description

Technical Field

[0001] This utility model belongs to the field of land planning and surveying technology, and in particular relates to a surveying device for land planning. Background Technology

[0002] Land planning surveying equipment is an important tool to ensure the rational use of land resources. Its design must take into account terrain adaptability, measurement accuracy and operational efficiency.

[0003] Traditional measuring devices typically use a tripod to stabilize the measuring head. However, the tripod becomes loose after being extended, requiring operators to use bolts to tighten it. This method involves tightening multiple bolts during both unfolding and folding, resulting in numerous steps, low efficiency, and inconvenience during use. Summary of the Invention

[0004] The purpose of this utility model is to provide a surveying device for land planning. By setting up a support component, specifically by forcefully pulling the support rod to unfold it, the support rod is attracted and fixed by magnetic blocks on the limiting frame, keeping the support rod in an unfolded state. After unfolding the support rod in the same way, it can be placed on the ground. This method can quickly open and fix the support rod, and the operation is simple and convenient. It solves the problem that the tripod is in a loose state after being pulled out, and the staff needs to use bolts to lock and fix the pulled-out tripod. This method requires tightening multiple bolts when unfolding and storing, which is inefficient due to many operation steps.

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 scope of protection of the present utility model.

[0035] Please see Figures 1-5 As shown, this utility model is a surveying device for land planning, including a surveying head 1, a connecting rod 11 fixedly connected to the bottom of the surveying head 1, and a threaded limiting ring 12 threadedly connected to the bottom of the connecting rod 11, and also including:

[0036] Support mechanism 2 is installed on the outside of connecting rod 11 and is used to support measuring head 1 on the ground;

[0037] The threaded limiting ring 12 is installed on the connecting rod 11 by means of threads and is detachable. After the threaded limiting ring 12 is installed on the connecting rod 11, it is used to limit the connecting rod 11.

[0038] The support mechanism 2 includes a circular fixed seat 21 that is slidably connected to the outside of the connecting rod 11. Three limiting frames 23 are fixedly connected to the top of the circular fixed seat 21, and magnetic blocks 231 are fixedly connected to the inner side of the limiting frames 23.

[0039] Support components 22, three sets of support components 22 are arranged in a circumferential array on the outside of the circular fixed base 21;

[0040] Fixing component 24 is mounted on the bottom of the circular mounting base 21 and is used to fix the connecting rod 11; and

[0041] Three support plates 25 are fixedly connected to the bottom of the circular base 21;

[0042] Among them, the three sets of support components 22 form a tripod arrangement to maintain the stability of the support.

[0043] The support assembly 22 includes a support rod 221 hinged to the outside of the circular fixed base 21. A square groove 222 is provided inside the support rod 221. A tripod slot 223 is provided at the top and bottom of the inner wall of the square groove 222.

[0044] In this method, the support rod 221 contacts the magnetic block 231 after unfolding, and the support rod 221 is magnetically attracted and fixed. When the support rod 221 is pulled forcefully to unfold, the magnetic block 231 on the limiting frame 23 attracts and fixes the support rod 221, keeping the support rod 221 in an unfolded state. After unfolding the support rod 221 in the same way, the support rod 221 can be placed on the ground. This method can quickly open and fix the support rod 221, and the operation is simple and convenient.

[0045] The fixing component 24 includes a fixing block 241 fixedly connected to the bottom of the circular fixing base 21. A threaded knob 242 is threadedly connected to the fixing block 241, and the end of the threaded knob 242 facing the connecting rod 11 contacts the surface of the connecting rod 11.

[0046] A fixing block 251 is fixedly connected to the side of the support plate 25 facing the support rod 221. The fixing block 251 has slots 252 at the top and bottom. A locking block 253 is slidably connected inside the slots 252. A telescopic rod 254 is fixedly connected to the inside of the locking block 253. The other end of the telescopic rod 254 is fixedly connected to the inner wall of the slots 252. A spring 255 is sleeved on the outside of the telescopic rod 254. When the unfolded support rod 221 is pushed, it will disengage from the magnetic block 231 and be inserted into the fixing block 251 through the square slot 222. When the locking block 253 moves to the tripod slot 223, the locking block 253 will spring into the tripod slot 223 under the action of elasticity to fix the support rod 221, thereby quickly completing the storage.

[0047] The outer side of the card block 253 is set with three legs, and the shape of the three legs on the outer side of the card block 253 is adapted to the three-legged card slot 223. The fixing block 251 is inserted into the square slot 222.

[0048] The telescopic rod 254 is provided with an outer rod and an inner rod. The outer rod is connected to the inner wall of the slot 252, and the inner rod is connected to the surface of the block 253. One end of the spring 255 is fixedly connected to the surface of the block 253, and the other end of the spring 255 is fixedly connected to the inner wall of the slot 252.

[0049] When the locking block 253 is compressed, it will compress the spring 255. The spring 255 will use the compression to store force and spring back the locking block 253 to reset.

[0050] A fixing rod 211 is fixedly connected to the outside of the circular fixing base 21. A placement platform 212 is fixedly connected to the end of the fixing rod 211. A ring magnet is installed on the placement platform 212. The placement platform 212 is used to place the monitor and fix the monitor by magnetic attraction.

[0051] One specific application of this embodiment is:

[0052] In use, insert the connecting rod 11 into the circular fixed base 21, and then install the threaded limiting ring 12 on the bottom thread of the connecting rod 11 to limit the connecting rod 11. This method allows for the replacement of different measuring heads 1 on the circular fixed base 21. When measurement is required, pull the support rod 221 forcefully, and the support rod 221 will push the locking block 253 into the locking groove 252. At this time, the telescopic rod 254 retracts, and the spring 255 is squeezed, allowing the support rod 221 to smoothly disengage from the fixing block 251, and the support rod 221 can be unfolded. After the support rod 221 is unfolded, it will be attracted and fixed by the magnetic block 231 on the limiting frame 23, keeping the support rod 221 in the unfolded state. After unfolding the support rod 221 in the same way, the support rod 221 can be placed on the ground. This method can quickly open and fix the support rod 221, and the operation is simple and convenient.

[0053] Then push or pull the connecting rod 11 to adjust the measuring height of the measuring head 1. After adjustment, turn the threaded knob 242 clockwise to make it contact the connecting rod 11 and fix the position of the connecting rod 11. At this time, the position of the measuring head 1 is fixed, and the height adjustment is completed. Then place the measuring display on the placement platform 212. The placement platform 212 fixes the display by magnetic attraction, which makes it convenient for the staff to operate and observe the measurement results.

[0054] When the measurement is complete and storage is required, remove the monitor from the placement platform 212 and push the support rod 221 forcefully to disengage it from the magnetic block 231. The support rod 221 then inserts into the fixing block 251 through the square slot 222. During the insertion process, the locking block 253 is pushed into the locking slot 252. When the locking block 253 moves into the tripod locking slot 223, it will spring into the tripod locking slot 223 under the action of elasticity, thereby locking and fixing the support rod 221, and quickly completing the storage.
