Description

Technical Field

[0001] The utility model relates to the technical field of measuring instrument brackets, and particularly relates to a measuring instrument bracket for project cost that can adapt to various terrains. Background Technique

[0002] Engineering survey is an important part of project cost, because it is a necessary work in the early stage of construction projects, involving the measurement of land, terrain, landform, geology, etc. It is the basis for the land required for construction projects. In engineering surveys, various measuring instruments are often used. The measuring instrument bracket for project cost that can adapt to various terrains is a measuring tool support device designed specifically for the field of project cost. It can remain stable under complex and changeable terrain conditions to ensure the accuracy of measurement data;

[0003] Nowadays, most of the support legs on the measuring instrument bracket can be telescopically adjusted. The telescopically adjustable support legs enable the measuring instrument bracket to not only be applicable to different terrains, but also keep the measuring instrument on the measuring instrument bracket in a horizontal and stable state by adjusting the heights of different support legs. However, when the measuring instrument bracket is adjusted to be horizontally stable, it is a small-scale adjustment. Most traditional measuring instrument brackets need to manually control the telescopic length of the support legs to make the adjustment, so that the operator needs to very finely control the force to find the best combination of support leg heights to ensure the horizontal stability of the measuring instrument. This kind of fine operation often wastes a lot of time, not only increasing the work difficulty, but also possibly affecting the work efficiency of the operator. Content of the Utility Model

[0004] The purpose of the utility model is to provide a measuring instrument bracket for project cost that can adapt to various terrains to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A measuring instrument bracket for project cost that can adapt to various terrains includes a mounting base. A plurality of first support legs are limitably and movably arranged on the mounting base. A second support leg is limitably and movably arranged on the first support leg. A support end is arranged at the bottom end of the second support leg. An adjusting structure for adjusting the position of the support end is arranged on the second support leg. The adjusting structure includes a connecting frame and a first lead screw. The connecting frame is limitably and movably arranged inside the second support leg, and the bottom end of the connecting frame is fixedly connected to the top end of the support end.

[0007] Preferably, fixing bolts for fixing the measuring instrument are arranged on the mounting base.

[0008] Preferably, positioning bolts for positioning the second support leg are arranged on the first support leg.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , a measuring instrument bracket for project cost that adapts to various terrains, including a mounting base 1. A plurality of first support legs 2 are limit-actively arranged on the mounting base 1. A second support leg 3 is limit-actively arranged on the first support leg 2. The bottom end of the second support leg 3 is provided with a support end 4. An adjusting structure for adjusting the position of the support end 4 is arranged on the second support leg 3. The adjusting structure includes a connecting frame 8 and a first lead screw 10. The connecting frame 8 is limit-actively arranged inside the second support leg 3, and the bottom end of the connecting frame 8 is fixedly connected to the top end of the support end 4. The mounting base 1 is the upper platform of the bracket and is used to directly contact the measuring instrument. The first support leg 2 is the intermediate link connecting the mounting base 1 and the second support leg 3, allowing the bracket to make preliminary angle adjustments to adapt to different terrain conditions. The mounting base 1 is used to directly contact the measuring instrument and is responsible for stably fixing the measuring instrument at the required position. The second support leg 3 can cooperate with the first support leg 2 to enable the measuring instrument bracket to perform height adjustment. The support end 4 is the component of the bracket in contact with the ground, responsible for stably fixing the bracket on the ground and providing a support point for the upper support structure. The inside of the second support leg 3 is designed with a cavity for installing adjusting structures such as the connecting frame 8 and the first lead screw 10. Through the installation of structures such as the connecting frame 8 and the first lead screw 10, as the user rotates the knob 7, the knob 7 is connected to the internal gear 16 through the rotating rod 15. The meshing relationship between the gear 16 and the gear 14 transmits the rotational movement to the first lead screw 10. The rotation of the first lead screw 10 causes the lead screw nut 11 to move up and down along the lead screw, and then drives the support end 4 to perform height adjustment through the connecting member 12 and the connecting rod 13, completing the height adjustment of one end of the measuring instrument bracket. This not only improves the applicability of the measuring instrument bracket, enabling it to perform measurement work on more terrains, but also significantly enhances the stability and accuracy of the bracket during rough horizontal stability adjustment, improving the practicality of the measuring instrument bracket.

[0020] Please refer to Figure 1 , fixing bolts 6 for fixing the measuring instrument are arranged on the mounting base 1. The mounting base 1 is the top platform of the bracket, and its main function is to serve as the support and fixing foundation for the measuring instrument. Through the fixing bolts 6, the mounting base 1 can firmly lock the measuring instrument at the required position, preventing it from moving or tilting during the measurement process.

[0021] Please refer to Figure 1 and Figure 2, a positioning bolt 5 for positioning the second support leg 3 is provided on the first support leg 2. After the second support leg 3 is adjusted to the required position, the positioning bolt 5 can be tightened to fix the second support leg 3, ensuring that the second support leg 3 will not move due to external forces during the measurement process, thus guaranteeing the accuracy of the measurement.

[0022] Please refer to Figure 3 and Figure 4 , two sets of mounting brackets 9 are fixedly arranged inside the second support leg 3. A first lead screw 10 is rotatably arranged on the mounting bracket 9. A lead screw nut 11 is meshed with the first lead screw 10. A plurality of connecting pieces 12 are fixedly arranged on the outside of the lead screw nut 11. A connecting rod 13 is fixedly arranged on the outside of the connecting piece 12. And one end of the connecting rod 13 is fixedly connected to the outside of the connecting frame 8. A rotating rod 15 is rotatably arranged on the second support leg 3. A first gear 16 is fixedly arranged at one end of the rotating rod 15. And the first gear 16 is located inside the second support leg 3. A second gear 14 is fixedly arranged at the top end of the first lead screw 10. And the second gear 14 is meshed with the first gear 16. A knob 7 is fixedly arranged at the other end of the rotating rod 15. And the knob 7 is located outside the second support leg 3. The two sets of mounting brackets 9 inside the second support leg 3 are the mounting bases for the first lead screw 10. When the first lead screw 10 rotates, the threads thereon will drive the meshed lead screw nut 11 to perform linear movement. The lead screw nut 11 is meshed with the first lead screw 10 and moves up and down with the rotation of the lead screw. A plurality of connecting pieces 12 are fixedly arranged on its outside, which are used to convert the rotational movement of the lead screw into the linear movement of the connecting rod 13. The connecting piece 12 connects the lead screw nut 11 and the connecting rod 13, ensuring that when the lead screw nut 11 moves, it can drive the connecting rod 13 to move together. One end of the connecting rod 13 is fixedly connected to the outside of the connecting frame 8, thus finally transmitting the rotational movement of the lead screw to the connecting frame 8 to realize the height adjustment of the support end 4. When the measuring instrument bracket is roughly leveled and stabilized during the support process, as the user rotates the knob 7, the knob 7 is connected to the internal first gear 16 through the rotating rod 15. The meshing relationship between the first gear 16 and the second gear 14 enables the rotational movement to be transmitted to the first lead screw 10. The rotation of the first lead screw 10 makes the lead screw nut 11 move up and down along the lead screw. The movement of the lead screw nut 11 is transmitted to the connecting frame 8 through the connecting piece 12 and the connecting rod 13, thereby driving the support end 4 to adjust the height and completing the adjustment of the height of one end of the measuring instrument bracket. This not only improves the applicability of the measuring instrument bracket, enabling it to perform measurement work on more terrains, but also significantly enhances the stability and accuracy of the bracket during rough horizontal stabilization adjustment, improving the practicality of the measuring instrument bracket.

[0023] Working principle: The mounting base 1 is the upper platform of the bracket, which is used to directly contact the measuring instrument. The first support leg 2 is the intermediate link connecting the mounting base 1 and the second support leg 3, allowing the bracket to make preliminary angle adjustments to adapt to different terrain conditions. The mounting base 1 is used to directly contact the measuring instrument and is responsible for stably fixing the measuring instrument at the required position. The second support leg 3 can cooperate with the first support leg 2 to enable the height adjustment of the measuring instrument bracket. The support end 4 is the component where the bracket contacts the ground, responsible for stably fixing the bracket on the ground and providing a support point for the upper support structure. There is a cavity designed inside the second support leg 3 for installing adjustment structures such as the connecting frame 8 and the first lead screw 10. Through the installation of structures such as the connecting frame 8 and the first lead screw 10, as the user rotates the knob 7, the knob 7 is connected to the internal first gear 16 through the rotating rod 15. The meshing relationship between the first gear 16 and the second gear 14 transmits the rotational motion to the first lead screw 10. The rotation of the first lead screw 10 causes the lead screw nut 11 to move up and down along the lead screw, and then drives the support end 4 to adjust the height through the connecting piece 12 and the connecting rod 13, enabling the height of one end of the measuring instrument bracket to be adjusted. After completing the height adjustment of one end of the measuring instrument bracket, this not only improves the applicability of the measuring instrument bracket, enabling it to perform measurement work on more terrains, but also significantly enhances the stability and accuracy of the bracket during rough horizontal stability adjustment, improving the practicality of the measuring instrument bracket. The mounting base 1 is the top platform of the bracket, and its main function is to serve as the support and fixing foundation for the measuring instrument. Through the fixing bolt 6, the mounting base 1 can firmly lock the measuring instrument at the required position to prevent it from moving or tilting during the measurement process. When the second support leg 3 is adjusted to the required position, the positioning bolt 5 can be tightened to fix the second support leg 3, ensuring that the second support leg 3 will not move due to external forces during the measurement process, thus guaranteeing the accuracy of the measurement. The two groups of mounting frames 9 inside the second support leg 3 are the installation bases for the first lead screw 10. When the first lead screw 10 rotates, the threads on it will drive the meshing lead screw nut 11 to perform linear movement. The lead screw nut 11 meshes on the first lead screw 10 and moves up and down with the rotation of the lead screw. Multiple groups of connecting pieces 12 are fixedly arranged on its outside for converting the rotational motion of the lead screw into the linear motion of the connecting rod 13. The connecting piece 12 connects the lead screw nut 11 and the connecting rod 13 to ensure that when the lead screw nut 11 moves, it can drive the connecting rod 13 to move together. One end of the connecting rod 13 is fixedly connected to the outside of the connecting frame 8, thus finally transmitting the rotational motion of the lead screw to the connecting frame 8 to achieve the height adjustment of the support end 4. When the measuring instrument bracket is making rough horizontal stability adjustment during the support process, as the user rotates the knob 7, the knob 7 is connected to the internal first gear 16 through the rotating rod 15. The meshing relationship between the first gear 16 and the second gear 14 enables the rotational motion to be transmitted to the first lead screw 10. The rotation of the first lead screw 10 causes the lead screw nut 11 to move up and down along the lead screw. The movement of the lead screw nut 11 is transmitted to the connecting frame 8 through the connecting piece 12 and the connecting rod 13, and then drives the support end 4 to adjust the height.Complete the adjustment of the height at one end of the measuring instrument support. This not only improves the applicability of the measuring instrument support, enabling it to perform measurement work on more terrains, but also significantly enhances the stability and accuracy of the support during rough horizontal stability adjustment, thereby improving the practicality of the measuring instrument support.
