Description
Technical Field
[0001] The utility model belongs to the technical field of supporting brackets, and particularly relates to a tripod for measuring instruments. Background Technique
[0002] A level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the principle of leveling measurement. The main components include a telescope, a tubular level (or compensator), a vertical axis, a base, and foot screws. It is divided into a tilting level, an automatic level, a laser level, and a digital level (also known as an electronic level) according to the structure. It is divided into a precision level and a general level according to the accuracy. The level needs to be supported and fixed during actual use and needs to be used in conjunction with a tripod. The tripod mainly plays a supporting role. The tripod and the base of the level are usually connected by bolts. However, since the tripod is usually used in harsh environments such as outdoors and construction sites, foreign matters such as dirt are likely to accumulate at the connection between the bolt and the tripod, affecting the stability of the cooperation between the bolt and the tripod. Moreover, the lower end face area of the tripod is small, making it difficult to clean and screw the bolt, affecting the tightness of the bolt installation. As a result, after the level is installed on the tripod, the bolt may loosen during actual use or movement, which is not conducive to ensuring the stability and measurement accuracy of the level during measurement. Content of the Utility Model
[0003] In view of this, the present utility model aims to provide a tripod for measuring instruments to solve the problem that the operation of the bolt connection in the existing tripod for measuring instruments is inconvenient and affects the tightness of the bolt installation.

The telescopic legs are at least evenly arranged in three along the circumferential direction of the base, and each telescopic leg is rotatably installed on the base; a connecting member for connecting a measuring instrument is provided on the base, and an assembly hole for facilitating the connecting member to pass through is provided on the base. One end of the connecting member passing through the assembly hole has an external thread, and the other end is provided with a limiting component; the limiting component includes a limiting block and handle members provided around the limiting block. The handle members are at least evenly arranged in two along the circumferential direction of the limiting block. Each handle member is rotatably installed at one end on the limiting block, and the other end is provided with an elastic element that can cooperate with the base.
[0006] Further, an assembly groove for cooperating with the handle member is provided on one side of the limiting block facing the base.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0026] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0027] A tripod for a measuring instrument, such as Figures 1 to 6 shown, includes a base 1 and telescopic legs 2 arranged around the base 1. The telescopic legs 2 are at least evenly arranged in three around the circumference of the base 1, and each telescopic leg 2 is rotatably installed on the base 1. Specifically, the telescopic legs 2 can be set to three, four or more, and the telescopic legs 2 can adopt the telescopic legs used on the existing tripods. The fixed end of the telescopic leg 2 can be rotatably installed on the base 1 through a rotating shaft, and the base 1 is provided with a shaft hole matching the rotating shaft. Those skilled in the art can also select a suitable telescopic leg 2 and its installation method according to actual needs. The present invention does not involve the improvement of the telescopic leg 2, so it will not be elaborated here.
[0028] A connecting member 3 for connecting a measuring instrument is provided on the above-mentioned base 1. The base 1 is provided with an assembly hole 8 for facilitating the connecting member 3 to pass through. One end of the connecting member 3 passing through the assembly hole 8 is provided with an external thread, and the other end is provided with a limiting component; the limiting component includes a limiting block 4 and handle members 5 arranged around the limiting block 4. The handle members 5 are at least evenly arranged in two around the circumference of the limiting block 4. The handle members 5 are at least evenly arranged in two around the circumference of the limiting block 4. Each handle member 5 is rotatably installed at one end on the limiting block 4, and the other end is provided with an elastic element 6 that can cooperate with the base 1. Among them, the outer diameter of the limiting block 4 is larger than the aperture of the assembly hole 8 to realize the limitation of the connecting member 3.
[0029] Exemplarily, the connecting member 3 can be fixed on the limiting block 4 or can be installed and fixed on the limiting block 4 by screws. Those skilled in the art can also select a suitable method to connect the limiting block 4 and the connecting member 3 according to actual needs to achieve a stable connection between the two, which will not be elaborated here. By providing an external thread on the connecting member 3, the connecting member 3 can be threadedly connected with the base of the level to realize the stable installation of the level on this tripod.
[0030] In the actual application process, two, three or more handle members 5 can be evenly arranged around the limiting block 4, and there is an accommodation gap for accommodating fingers between two adjacent handle members 5. By rotatably installing the handle members 5 on the limiting block 4, when an operator needs to rotate and screw the connecting member 3, the handle members 5 can be rotated to a horizontal state. The multiple handle members 5 can form a structure similar to a handwheel, providing a larger operating structure for the operator after the telescopic legs 2 of the tripod are opened, so as to facilitate the operator to conveniently rotate the limiting block 4 and the connecting member 3 and reduce the screwing difficulty of the connecting member 3.
[0031] In addition, after the level is installed in place, the operator can also rotate the handle member 5 to the vertical state, and use the elastic element 6 on the handle member 5 to press against the bottom surface of the base 1. Relying on the restoring elastic force of the elastic element 6, a downward force is applied to the limiting block 4 and the connecting member 3, reducing the possibility of loosening of the limiting block 4 and the connecting member 3 due to the movement of the tripod, which is beneficial to ensuring the stability and measurement accuracy of the level during the measurement process.
[0032] Optionally, an assembly groove 9 for cooperating with the handle member 5 is provided on one side of the limiting block 4 facing the base 1. Exemplarily, the handle member 5 is rotationally installed on the limiting block 4 through a rotating shaft. An installation hole for cooperating with the rotating shaft is provided at a position corresponding to the assembly groove 9 on the limiting block 4, and the installation hole is communicated with the assembly groove 9. Among them, a through hole for cooperating with the rotating shaft can also be provided on the handle member 5. Those skilled in the art can also select other ways to install the handle member 5 according to actual needs to achieve the rotational installation of the handle member 5 on the limiting block 4, which will not be elaborated here.
[0033] In the actual application process, by providing the assembly groove 9 on the limiting block 4 for cooperating with the handle member 5, after the handle member 5 is rotated to the horizontal state, the assembly groove 9 can still play a good limiting role on the end of the handle member 5, which is beneficial to improving the structural strength and stability of the connection between the handle member 5 and the limiting block 4, so as to facilitate the operator to use the handle member 5 to drive the limiting block 4 and the connecting member 3 to rotate, realizing the assembly of the level on this tripod.
[0034] Optionally, a deformation hole 11 is provided on the elastic element 6, and an arc-shaped protrusion 10 capable of cooperating with the deformation hole 11 is provided at a position corresponding to the assembly groove 9 on the limiting block 4. Exemplarily, the arc-shaped protrusion 10 is fixed on the limiting block 4. By providing the arc-shaped protrusion 10 and using the cooperation between the arc-shaped protrusion 10 and the deformation hole 11 on the elastic element 6, a certain limiting effect can be exerted on the elastic element 6 and the handle member 5, ensuring that the elastic element 6 can continuously and stably press against the bottom surface of the base 1, thereby realizing the limitation of the limiting block 4 and the connecting member 3. In addition, the deformation hole 11 is also beneficial to improving the elastic deformation performance of the elastic element 6, facilitating the operator to rotate the handle member 5 on the premise of ensuring the cooperation effect between the elastic element 6 and the bottom surface of the base 1.
[0035] Optionally, an annular card slot 7 for cooperating with the elastic element 6 is provided on the base 1. The annular card slot 7 is coaxially arranged with the connecting member 3, and a guiding surface for facilitating the elastic element 6 to move into or out of the annular card slot 7 is provided on the elastic element 6. Exemplarily, the guiding surface can adopt an arc surface to facilitate the elastic element 6 to move into or out of the annular card slot 7. By providing the annular card slot 7 on the base 1 for cooperating with the elastic element 6, the annular card slot 7 can play a good limiting role on the elastic element 6, further improving the stability of the cooperation between the elastic element 6 and the base 1 and enhancing the limiting effect of the elastic element 6 on the limiting block 4 and the connecting member 3.
[0036] Optionally, one end of the elastic element 6 facing the base 1 is provided with anti-slip patterns, and the other end is arranged on the handle member 5. Exemplarily, the elastic element 6 is made of elastic rubber or spring steel. When the elastic element 6 is made of elastic rubber, the elastic element 6 can be fixedly adhered to the handle member 5 by an adhesive. When the elastic element 6 is made of spring steel, the elastic element 6 can be fixedly installed on the handle member 5 by screws. By providing anti-slip patterns on the elastic element 6 and using the anti-slip patterns to cooperate with the bottom surface of the base 1, it is also beneficial to improve the stability of the cooperation between the elastic element 6 and the base 1, and further reduce the possibility of accidental rotation of the handle member 5 during the movement and use of the tripod.
[0037] In the actual application process, by the cooperation of the arc-shaped protrusion 10 and the deformation hole 11 on the elastic element 6, and the cooperation of the elastic element 6 and the annular card slot 7 on the base 1, it can be ensured that after the handle member 5 rotates to the vertical state, the elastic element 6 can continuously and stably hold against the bottom surface of the base 1, thereby playing a limiting role on the limiting block 4 and the connecting member 3, and preventing the accidental rotation of the limiting block 4 and the connecting member 3 from causing the level to loosen.
[0038] The tripod for a measuring instrument described in the present utility model has the advantages of simple structure, easy installation, applicability, high stability and reliability. By rotatably installing the handle member on the limiting block, when an operator needs to rotate and screw the connecting member, the handle member can be rotated to the horizontal state, and multiple handle members can form a structure similar to a handwheel, so as to facilitate the operator to manually rotate the limiting block and the connecting member, reducing the screwing and assembling difficulty of the connecting member. At the same time, by rotating the handle member to the vertical state and using the elastic element on the handle member to hold against the bottom surface of the base, relying on the reset elastic force of the elastic element to apply a downward force to the limiting block and the connecting member, the possibility of loosening of the limiting block and the connecting member due to the movement of the tripod is reduced, which is beneficial to ensuring the stability and measurement accuracy of the level during the measurement process.
[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
