Description

Technical Field

[0001] The utility model relates to the technical field of cadastral survey assistance, and more specifically, to a ground guide pole assisted in cadastral survey. Background Art

[0002] Cadastral surveying involves the precise determination of the location, area, ownership, etc. of land. In actual surveying, the survey area may have complex terrain and diverse landforms, such as hills, gullies, forests, etc. This makes it difficult to determine the survey point, and clear markings are needed to assist surveyors in accurately finding the survey location.

[0003] Nowadays, when using a guide pole to insert into the ground, there is no corresponding external support structure to support the pole, which results in the need for construction workers to support the pole when in use to prevent the pole from tilting after being subjected to external impact force and affecting the accuracy of subsequent measurement results. Simple manpower support is not only time-consuming and labor-intensive, but also very likely to cause the pole to tilt due to the negligence of construction workers.

[0004] After searching, the Chinese patent with authorization announcement number CN217900863U discloses a cadastral survey ground guide pole connected and transmitted by a transmission plate and a pull rod, so that when the lifting sleeve is twisted along the outer side of the thread to lift, the mounting plate at the bottom of the fixed pipe can be lifted accordingly. The two ends of the pull rod are respectively connected to the mounting plate and the rotating frame through a rotating shaft, so that when the mounting plate is lifted, the pull rod provides the corresponding outer side spreading force to the spreading plate, so that the three groups of spreading plates can be synchronously rotated outward to spread and provide corresponding support force to the fixed pipe, thereby reducing the labor consumption of construction personnel and ensuring the stability of the fixed pipe when providing guidance.

[0005] However, in actual use, the cone can be inserted into the ground and supported on some surfaces, but on hard roads that are not suitable for insertion, manual support is still required, which is time-consuming and labor-intensive. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a ground guide pole assisted by cadastral surveying to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a ground guide pole for cadastral surveying assistance, comprising a steering rod, a telescopic mechanism is arranged at the bottom end of the steering rod, a fixed tube is arranged at the bottom end of the telescopic mechanism, a sliding support mechanism is arranged on the fixed tube, and a pointed cone is fixedly connected to the bottom end of the fixed tube;

[0008] The sliding support mechanism includes two bumps fixedly connected to the outer wall of the fixed tube, and the two bumps are symmetric about the axis of the fixed tube. A sliding groove is formed in the bump. The outer side of the fixed tube is slidably connected with a support seat through the sliding groove. Three support legs are hinged to the bottom end of the support seat, and the three support legs are annularly arranged around the support seat. Bases are arranged at the bottom ends of the three support legs, and a stabilizing mechanism is arranged at the bottom end of the fixed tube; a screw rod is arranged in the sliding groove at the top end of the support seat, and a nut is threadedly connected to one end of the screw rod.

[0009] In order to achieve the effect of restricting the telescopic tube so that it can only move up and down in the fixed tube, preferably, the telescopic mechanism includes a telescopic tube fixedly connected to the bottom end of the steering rod. Two vertical blocks are fixedly connected to the outer wall of the telescopic tube. Vertical grooves matching the vertical blocks are formed in the fixed tube, and the telescopic tube and the fixed tube are slidably connected through the vertical blocks and the vertical grooves.

[0010] In order to achieve the effect of fixing the telescopic tube after it is pulled out of the fixed tube to a certain position, preferably, two fixing plates are fixedly connected to the outer wall of the fixed tube. A pull rod is arranged on one side of the fixing plate. One end of the pull rod extends to one side of the fixing plate and is fixedly connected to a plug pin. One end of the plug pin penetrates through the outer wall of the fixed tube and one side of the telescopic tube. Placing grooves are formed on one side of the fixing plate and one end of the plug pin. A spring is arranged between the placing grooves on one side of the fixing plate and one end of the plug pin.

[0011] In order to achieve the effect of making the support legs support more stably, preferably, the stabilizing mechanism includes a rotating disk threadedly connected to the bottom end of the outer wall of the fixed tube. A convex ring is fixedly connected to the outer wall of the rotating disk. A fixed ring is slidably connected to the outer wall of the rotating disk through the convex ring. Three support rods are hinged to the outer wall of the fixed ring, and the three support rods are annularly arranged around the fixed ring. The other ends of the support rods are hinged to the support legs.

[0012] In order to achieve the effect of having better grip on the ground after the support legs change the angle, preferably, the base includes a universal joint fixedly connected to the bottom end of the support leg. A universal ball is rotatably connected to the bottom end of the universal joint, and a gasket is fixedly connected to the bottom end of the universal ball.

[0013] In order to achieve the effect of preventing damage to the telescopic tube when the plug pin is inserted, preferably, the two fixing plates, the pull rod and the plug pin are symmetric about the axis of the fixed tube, and one end of the plug pin is made of rubber material.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. By setting the steering rod, the pointed cone, the stabilizing mechanism and the sliding support mechanism, when in use, it can be judged according to the environment whether the pointed cone can be inserted into the ground. By loosening the nut and sliding the support base, the support base can be adjusted to a certain height. By adjusting different heights, when the pointed cone is inserted into the ground, it can provide an auxiliary support effect for the equipment. When the pointed cone cannot be inserted into the ground, the support base is lowered so that the support legs play a supporting role. Since the pointed cone is a heavy object, when it is suspended, it will improve the stability of the support base and prevent the equipment from tipping due to external forces. By rotating the rotating disc, the angle of the support legs can be adjusted. After the support legs are opened and stabilized at a certain angle, the nut is tightened to complete the fixation. The support rod provides corresponding support force for the support legs, reducing the labor consumption of construction workers and ensuring the stability of the equipment when providing guidance.

[0016] 2. By setting the telescopic mechanism, when in use, the telescopic tube is pulled out through the steering rod. When the telescopic tube is pulled to a certain position, the pin rebounds into the telescopic tube to complete the plug-in fixation due to the elastic force of the spring. When it is necessary to retract, the pull rod is pulled to drive the pin to move, canceling the fixation of the telescopic tube, and then the telescopic tube falls back into the fixed tube. The operation is simple, and the telescoping of the telescopic tube makes the equipment occupy less space and is more convenient to carry.

[0017] 3. By setting the base, when the support legs are opened, they must be inclined. By setting a universal joint at its bottom, a universal ball is arranged inside the universal joint, and a gasket is fixed at the bottom end of the universal ball, so that the gasket rotates in the universal joint along with the universal ball. The gasket can be flexibly adjusted in terms of orientation, making the support of the equipment more stable. Brief Description of the Drawings

Detailed implementation manner

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As shown in the attached Figures 1-6 The ground guiding benchmark for cadastral survey shown in the figure includes a steering rod 1. An expansion mechanism is provided at the bottom end of the steering rod 1. A fixed tube 2 is provided at the bottom end of the expansion mechanism. A sliding support mechanism is provided on the fixed tube 2. A sharp cone 3 is fixedly connected to the bottom end of the fixed tube 2;

[0027] The sliding support mechanism includes two bumps 4 fixedly connected to the outer wall of the fixed tube 2, and the two bumps 4 are symmetric about the fixed tube 2. A sliding groove 5 is opened on the bump 4. The outside of the fixed tube 2 is slidably connected to a support base 6 through the sliding groove 5. Three support legs 7 are hinged to the bottom end of the support base 6, and the three support legs 7 are annularly arranged around the support base 6. Bases are provided at the bottom ends of the three support legs 7. A stabilizing mechanism is provided at the bottom end of the fixed tube 2; A screw 8 is provided in the sliding groove 5 at the top end of the support base 6, and one end of the screw 8 is threadedly connected to a nut 9.

[0028] Specifically, when using this structure, first judge whether the ground is suitable for inserting the sharp cone 3. When it is suitable for inserting the sharp cone 3, loosen the nut 9, insert the sharp cone 3 into the ground, and then slide the support base 6 to adjust the support base 6 to a certain height. Open the support legs 7 through the stabilizing mechanism and stabilize them at a certain angle, and then tighten the nut 9. Stretch the device through the telescopic structure;

[0029] When it is not suitable for inserting the sharp cone 3, loosen the nut 9, slide the support base 6, move the support base 6 down to a certain position, open the support legs 7 through the stabilizing mechanism and stably place them on the ground, and the sharp cone 3 does not touch the ground. Then tighten the nut 9 and stretch the device through the telescopic structure.

[0030] In a specific embodiment, as shown in the attached Figure 1 、 4, as shown in Figure 6, the telescopic mechanism includes a telescopic tube 10 fixedly connected to the bottom end of the steering rod 1. Two vertical blocks 11 are fixedly connected to the outer wall of the telescopic tube 10. Vertical grooves 12 matching the vertical blocks 11 are provided inside the fixed tube 2, and the telescopic tube 10 is slidably connected to the fixed tube 2 through the vertical blocks 11 and the vertical grooves 12, so as to facilitate the telescopic tube 10 to move up and down only within the fixed tube 2.

[0031] Specifically, in this structure, the telescopic tube 10 is in the fixed tube 2 and can only move up and down due to the limitation of the vertical blocks 11 and the vertical grooves 12, achieving the telescopic effect.

[0032] In a specific embodiment, as shown in the appendix Figure 4 , two fixing plates 13 are fixedly connected to the outer wall of the fixed tube 2. A pull rod 14 is arranged on one side of the fixing plate 13. One end of the pull rod 14 extends to one side of the fixing plate 13 and is fixedly connected to a plug pin 15. One end of the plug pin 15 penetrates the outer wall of the fixed tube 2 and one side of the telescopic tube 10. Placing grooves 16 are provided on one side of the fixing plate 13 and one end of the plug pin 15. A spring 17 is provided between the placing grooves 16 on one side of the fixing plate 13 and one end of the plug pin 15, so as to fix the telescopic tube 10 after it is pulled out of the fixed tube 2 by a certain position.

[0033] Specifically, in this structure, when the steering rod 1 is pulled upward, the steering rod 1 drives the telescopic tube 10 to move upward. When it moves to a certain height, the plug pin 15 rebounds into the telescopic tube 10 under the elastic force of the spring 17 to complete the plug-in fixation. When the use is over, the plug pin 15 is driven to move by pulling the pull rod 14. When the plug pin 15 moves, the spring 17 is compressed, and the telescopic tube 10 is placed in the fixed tube 2.

[0034] In a specific embodiment, as shown in the appendix Figure 6 , the stabilizing mechanism includes a rotating disc 18 threadedly connected to the bottom end of the outer wall of the fixed tube 2. A convex ring 19 is fixedly connected to the outer wall of the rotating disc 18. The outer wall of the rotating disc 18 is slidably connected to a fixed ring 20 through the convex ring 19. Three support rods 21 are hinged to the outer wall of the fixed ring 20. The three support rods 21 are annularly arranged around the fixed ring 20 as the axis. The other end of the support rod 21 is hinged to the support leg 7, so as to make the support leg 7 support more stably.

[0035] Specifically, in this structure, when the support seat 6 moves, the rotating disc 18 is rotated to drive the fixed ring 20 to move, so that the support rods 21 expand outwards, and then the support legs 7 are opened at a certain angle, so that they are placed on the ground more stably, ensuring the stability of the equipment during use.

[0036] In a specific embodiment, as shown in the appendix Figure 5As shown in the figure, the base includes a universal shaft 22 fixedly connected to the bottom end of the support leg 7. The bottom end of the universal shaft 22 is rotatably connected to a universal ball 23, and the bottom end of the universal ball 23 is fixedly connected to a gasket 24, so that the support leg 7 has better grip on the ground after changing the angle.

[0037] Specifically, in this structure, when the support leg 7 is opened, although the support leg 7 is inclined, the gasket 24 at the bottom always fits the ground due to the universal ball 23.

[0038] In a specific embodiment, as shown in the attached Figure 4 figure, the two fixing plates 13, the pull rod 14 and the pin 15 are all symmetric about the fixed tube 2. One end of the pin 15 is made of rubber material, so as to prevent damage to the telescopic tube 10 when the pin 15 is inserted.

[0039] Specifically, in this structure, when the telescopic tube 10 in the fixed tube 2 is pulled out, by setting one end of the pin 15 to be made of rubber material, the impact force of the pin 15 on the telescopic tube 10 due to the spring 17 rebounding is reduced, preventing the pin 15 from damaging the telescopic tube 10.

[0040] The working principle of the present utility model: When in use, first judge whether the ground is suitable for inserting the pointed cone 3. When it is suitable for inserting the pointed cone 3, first loosen the nut 9, and then insert the pointed cone 3 into the ground. The support leg 7 contacting the ground drives the support base 6 to move upward. Then rotate the rotating disk 18 to adjust the angle of the support leg 7 so that it assists the pointed cone 3 to support the device. And when the support leg 7 is opened, although the support leg 7 is inclined, the gasket 24 at the bottom always fits the ground due to the universal ball 23. After that, tighten the nut 9 to complete the fixation. Then pull the steering rod 1 upward, and the steering rod 1 drives the telescopic tube 10 to move upward. When it moves to a certain height, the pin 15 rebounds into the telescopic tube 10 due to the elastic force of the spring 17 to complete the plug-in fixation;

[0041] When the ground is not suitable for inserting the pointed cone 3, first loosen the nut 9, and adjust the angle of the support leg 7 by rotating the rotating disk 18 so that the support leg 7 directly supports the device, and the pointed cone 3 does not contact the ground. When the support leg is opened, although the support leg 7 is inclined, the gasket 24 at the bottom always fits the ground due to the universal ball 23. After that, tighten the nut 9 to complete the fixation. Then pull the steering rod 1 upward, and the steering rod 1 drives the telescopic tube 10 to move upward. When it moves to a certain height, the pin 15 rebounds into the telescopic tube 10 due to the elastic force of the spring 17 to complete the plug-in fixation;

[0042] When it is necessary to pull out the tapered cone 3 at the end of use, pull out the tapered cone 3. If it is not necessary, directly start the following operations. By rotating the rotating disc 18 and lifting the device, the support base 6 and the support leg 7 fall to the bottom end of the sliding groove 5 due to the factors of gravity and the cancellation of the fixation with the support rod 21. Subsequently, loosen the nut 9, let it fall along the sliding groove 5 to the top end of the support base 6, and then tighten the nut 9 to fix the position of the support base 6. Subsequently, pull the pull rod 14, the pull rod 14 drives the bolt 15 to move. When the bolt 15 moves, it compresses the spring 17 and pulls it out from the telescopic tube 10. Subsequently, the telescopic tube 10 falls into the fixed tube 2.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
