[0002] Distance measurement is another important method in land surveying. Commonly used distance measuring instruments include rangefinders and electronic rangefinders. Distance measurement can be used to measure the distance between ground features, the height of buildings, and so on.

[0003] In the prior art, Chinese Patent Publication No. CN218599341U discloses a land surveying and mapping device. The land surveying and mapping device includes a surveyor for surveying and mapping land, a support base for mounting and fixing the surveyor, and multiple support rods spaced apart circumferentially along the support base. The body of the fixing member is located at the end of the support rod away from the surveyor, and the body can rotate relative to the support rod so that the fixing part or the moving part abuts against the placement plane.

[0004] After use, the aforementioned land surveying and mapping devices often cannot be stowed away, resulting in a large overall size or the inability to keep the device horizontal and independent after stowing away, which is inconvenient for personnel to move and transport. Based on this, we propose a land ranging device. Utility Model Content

[0005] The purpose of this utility model is to provide a land ranging device to solve the problems mentioned in the background art, such as the inability to store the support rod, resulting in a large overall size or the inability to keep the device horizontally and independently after storing the support rod, which makes it inconvenient for personnel to move and transport the ranging device.

[0006] The technical solution of this utility model is: a land ranging device, including a detector body, a support plate fixedly connected to the bottom surface of the detector body, a plurality of connecting columns fixedly connected at equal intervals around the periphery of the support plate, a first support rod fixedly connected to one end of each connecting column, a second support rod disposed below the first support rod, and further comprising:

[0007] A connecting component is located below the detector body, and the first support rod and the second support rod are connected by the connecting component.

[0008] Preferably, the connecting assembly includes a connecting rod located between the first support rod and the second support rod. Rotating shafts are fixedly connected to the top and bottom of the outer wall of the connecting rod, respectively. The rotating shafts penetrate the side wall of the connecting rod and extend to the outside. Sleeves are rotatably fitted at both ends of the two rotating shafts. The two sleeves are fixedly connected to the side walls of the first and second support rods, respectively. A placement groove is formed at one end of the rotating shaft. A connecting ring is fixedly connected to the inner wall of the placement groove. A tension spring is fixedly connected to the top of the connecting ring. A pull rod is fixedly connected to the top of the tension spring. An L-shaped rod is fixedly connected to the periphery of the pull rod. A first limiting groove is formed at one end of the sleeve on the same side, and the L-shaped rod engages with the first limiting groove.

[0009] Preferably, the tension spring is sleeved around the periphery of the pull rod, and one end of the pull rod passes through the tension spring and extends into the connecting ring.

[0010] Preferably, one end of the upper sleeve is provided with a second limiting groove, the angle between the second limiting groove and the first limiting groove is 90 degrees, and one end of the lower sleeve is provided with a third limiting groove, the angle between the third limiting groove and the first limiting groove is 90 degrees.

[0011] Preferably, a positioning post is fixedly connected to the bottom end of the second support rod, and the positioning post has an inverted conical structure.

[0012] Preferably, the sum of the lengths of the second support rod and the third limiting groove is less than the length of the first support rod, and the sum of the radius of the support plate and the length of the connecting column is greater than the length of the connecting rod.

[0013] This utility model provides an improved land ranging device, which has the following improvements and advantages compared with the prior art:

[0014] Equipped with a connecting component, when a person pulls the lever, the lever stretches the spring outward. At this time, the other end of the spring slides out of the connecting ring, and one end of the L-shaped rod slides out of the first limiting groove, thereby canceling the limiting. Rotating the second support rod and releasing the lever, the second support rod drives the sleeve fixedly connected to it to rotate. When the third or second limiting groove rotates to be parallel to the L-shaped rod, the L-shaped rod slides into it and engages with it, thereby adjusting the angle between the first support rod, the second support rod, and the connecting rod. This allows the device to be placed horizontally and independently after the second support rod and the connecting rod are stored, and the volume is reduced, making it easy for personnel to move or transport the device.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] like Figure 1 - Figure 5 As shown, a land ranging device includes a detector body 1, a support plate 2 fixedly connected to the bottom surface of the detector body 1, a plurality of connecting columns 3 fixedly connected at equal intervals around the periphery of the support plate 2, a first support rod 4 fixedly connected to one end of the connecting column 3, a second support rod 5 disposed below the first support rod 4, and a connecting assembly located below the detector body 1. The first support rod 4 and the second support rod 5 are connected by the connecting assembly.

[0025] Furthermore, the connecting assembly includes a connecting rod 6, which is located between the first support rod 4 and the second support rod 5. The top and bottom of the outer wall of the connecting rod 6 are respectively fixedly connected to a rotating shaft 7. The rotating shaft 7 passes through the side wall of the connecting rod 6 and extends to the outside. Both ends of the two rotating shafts 7 are rotatably fitted with sleeves 8. The two sleeves 8 are respectively fixedly connected to the side wall of the first support rod 4 and the side wall of the second support rod 5. One end of the rotating shaft 7 is provided with a placement groove 10. The inner wall of the placement groove 10 is fixedly connected with a connecting ring 11. The top end of the connecting ring 11 is fixedly connected with a tension spring 12. The top of the tension spring 12 is fixedly connected with a pull rod 13. The periphery of the pull rod 13 is fixedly connected with an L-shaped rod 14. One end of the sleeve 8 on the same side is provided with a first limiting groove 15. The L-shaped rod 14 is engaged with the first limiting groove 15, which facilitates the adjustment of the position of the connecting rod 6 and the second support rod 5 through the L-shaped rod 14.

[0026] Furthermore, the tension spring 12 is sleeved around the pull rod 13, and one end of the pull rod 13 passes through the tension spring 12 and extends into the connecting ring 11, so that the pull rod 13 can be moved when the tension spring 12 rebounds.

[0027] Furthermore, a second limiting groove 16 is provided at one end of the upper sleeve 8, and the included angle between the second limiting groove 16 and the first limiting groove 15 is 90 degrees. A third limiting groove 17 is provided at one end of the lower sleeve 8, and the included angle between the third limiting groove 17 and the first limiting groove 15 is 90 degrees, so that it can be placed horizontally and independently after the second support rod 5 and the connecting rod 6 are housed.

[0028] Furthermore, a positioning post 18 is fixedly connected to the bottom end of the second support rod 5. The positioning post 18 has an inverted conical structure, which makes it easy for personnel to insert the positioning post 18 into the soil when measuring distance.

[0029] Furthermore, the sum of the lengths of the second support rod 5 and the positioning post 18 is less than the length of the first support rod 4, so that the second support rod 5 and the positioning post 18 will not contact the bottom of the support plate 2 when stored. The sum of the radius of the support plate 2 and the length of the connecting post 3 is greater than the length of the connecting rod 6, so that when the second support rod 5 and the connecting rod 6 are stored, the multiple connecting rods 6 will not contact each other, avoiding insufficient spacing between the multiple connecting rods 6, which would prevent them from being stored.

[0030] Working principle: When personnel need to perform surveying, they first pull the lever 13 closest to the second support rod 5 outwards. The lever 13 stretches the tension spring 12 outwards. At this time, the other end of the tension spring 12 slides out of the connecting ring 11, and one end of the L-shaped rod 14 slides out of the third limiting groove 17. The personnel then rotate the second support rod 5 away from the support plate 2 and release the lever 13. The second support rod 5 drives the sleeve 8, which is fixedly connected to it, to rotate. When the first limiting groove 15 rotates to be parallel to the L-shaped rod 14, one end of the L-shaped rod 14 slides into the first limiting groove 15 and connects with it. At this time, the angle between the second support rod 5 and the connecting rod 6 is 180 degrees. Then, the personnel pull the other lever 13, and the lever 1... 3. Pull the tension spring 12 outward. At this time, the other end of the tension spring 12 slides out of the connecting ring 11, and one end of the L-shaped rod 14 slides out of the second limiting groove 16. The personnel rotate the connecting rod 6 towards the support plate 2 and release the pull rod 13. The connecting rod 6 drives the corresponding rotating shaft 7 to rotate around the corresponding sleeve 8. When the L-shaped rod 14 is parallel to the first limiting groove 15, one end of the L-shaped rod 14 slides into the first limiting groove 15 and engages with the first limiting groove 15. At this time, the included angle between the first support rod 4 and the connecting rod 6 is 180 degrees. The first support rod 4 is parallel to the second support rod 5. Adjust each connecting component in sequence. Then insert the positioning column 18 into the bottom of the soil until the device is stable. The personnel can then measure the distance.

[0031] After the distance measurement is completed, the person first pulls the lower lever 13 outwards. Lever 13 stretches the tension spring 12 outwards. At this time, the other end of the tension spring 12 slides out of the connecting ring 11, and one end of the L-shaped rod 14 slides out of the first limiting groove 15. The person then rotates the second support rod 5 towards the support plate 2 and releases the lever 13. The second support rod 5 drives the sleeve 8, which is fixedly connected to it, to rotate. When the third limiting groove 17 rotates to be parallel to the L-shaped rod 14, one end of the L-shaped rod 14 slides into the third limiting groove 17 and connects with it. At this time, the angle between the second support rod 5 and the connecting rod 6 is 90 degrees. Then, the person pulls the upper lever 13 outwards. When the tension spring 12 is stretched, the other end of the tension spring 12 slides out of the connecting ring 11, and one end of the L-shaped rod 14 slides out of the first limiting groove 15. The operator rotates the connecting rod 6 towards the support plate 2 and releases the pull rod 13. The connecting rod 6 drives the upper rotating shaft 7 to rotate around the upper sleeve 8. When the L-shaped rod 14 is parallel to the second limiting groove 16, one end of the L-shaped rod 14 slides into the second limiting groove 16 and engages with the second limiting groove 16. At this time, the included angle between the first support rod 4 and the connecting rod 6 is 90 degrees, and the first support rod 4 is parallel to the second support rod 5. Each connecting component is adjusted in sequence. At this time, the size of the device becomes smaller, and the operator can easily move or transport the device.

[0032] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
