Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement brackets, in particular to a leveling instrument tripod with a semicircular top. Background Art

[0002] Tripods are widely used in the field of surveying and mapping to support equipment such as levels for data collection. Accurate measurement data is inseparable from the stable support of the tripod. In order to ensure the stability of the leg support, traditional tripods usually connect multiple legs through a hinge mechanism. This is also the connection method used by most traditional tripods.

[0003] However, since the measurement work requires constant changes in the measurement location, the support height of the tripod needs to be adjusted according to different usage environments. Each adjustment usually involves first adjusting the support height of the tripod to an appropriate position range, and visually adjusting it to a roughly stable state. Then, the level is installed flat on the base of the tripod with bolts. Subsequently, the tripod needs to be adjusted again to adjust the level to be more horizontally installed, and finally, the level is fine-tuned to a horizontal test state using the level.

[0004] It can be seen that the tripod needs to be adjusted multiple times from installation to use to ensure that the level can be fine-tuned to be level. However, due to the complexity of the actual measurement environment, it is difficult for the tripod to maintain its initial horizontal state after the level is installed after the first adjustment. It is necessary to repeatedly adjust the support state of the tripod with the level, so that the tripod installed in the traditional way of leveling is difficult to meet the use requirements. Not only is the operation cumbersome and troublesome, which reduces work efficiency, it is also easy to cause damage to the level, greatly reducing the safety of use.

[0005] Therefore, fast and stable debugging and installation of the level is very important for measurement work, and it is necessary to make improvements. Utility Model Content

[0026] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Depend on Figures 1 to 4 Some embodiments of the present invention relate to a level stand with a semicircular top, comprising:

[0028] The curved top member 1 is fixedly mounted on the tripod base 4;

[0029] The hinge shaft 2 includes an adapter portion 201 and a connecting portion 202. The adapter portion 201 is rotatably mounted in the curved top member 1. The connecting portion 202 is used to fix the level body 5 to the adapter portion 201.

[0030] The locking member 3 is used to lock the adapter portion 201 in the curved top member 1 .

[0031] In these embodiments, the surface of the curved top member 1 is an arc-shaped curved surface, and the curved top member 1 is fixedly connected to the tripod base 4, which can be specifically welded, integrally formed, etc. The adapter 201 is rotatably installed in the curved top member 1 in the form of a ball joint. Through the cooperation of the adapter 201 and the connecting portion 202, the leveling instrument body 5 can be stably installed on the curved top member 1, and then, with the coordinated cooperation of the locking member 3, the hinge member 2 can be locked in the curved top member 1, so that the leveling instrument body 5 is fixedly installed by fixing the hinge member 2, so that the leveling instrument body 5 can be fixedly installed at an appropriate angle. Specifically, after the tripod is placed stably, the leveling instrument body 5 is installed on the hinge member 2 through the connecting portion 202, and the leveling instrument body 5 is swung to approach a horizontal position, while driving the adapter 201 to rotate in the curved top member 1, and then the adapter 201 is locked by the locking member 3, and the fixing of the leveling instrument body 5 is completed. This effectively avoids the need to repeatedly adjust the tripod in order to place the level body 5, and can complete the installation faster and better, with more flexible and convenient operation. It also avoids adjusting the tripod along with the level body 5 during operation, and the installation is completed by directly adjusting the level body 5, which is beneficial to improving the safety of use. It not only greatly reduces the difficulty of installation and debugging, and improves work efficiency, but also can quickly and accurately debug the level body into place, making it more convenient and simple to use and more practical.

[0032] It should be understood that the angle range of the fine-tuning knob of a traditional level is usually within ±3°. When installing a tripod, the staff can visually place the tripod in a stable state. At this time, after installing the level, what is needed is a small range of angle adjustment (including but not limited to actual operations such as raising or lowering 5 degrees to 10 degrees, etc.), and then adjusting it through the level itself. This small range angle adjustment is achieved by adjusting the tripod legs and often requires gradual adjustment bit by bit, which is obviously cumbersome and complicated. By directly adjusting the angle of the level body 5, that is, adjusting the angle in a small range, the adjustment and installation can be completed quickly and accurately, which significantly improves the efficiency and accuracy of the adjustment and installation, and can also ensure the stability of the placement of the tripod and the level as a whole, so as to facilitate measurement and use.

[0033] In some embodiments of a semicircular top level tripod, the curved top member 1 includes a fixing portion 101 and a loading portion 102. The fixing portion 101 is formed at the bottom end of the curved top member 1, and the fixing portion 101 is fixedly connected to the tripod seat 4. The loading portion 102 is formed inside the curved top member 1, and the loading portion 102 is ball-jointedly connected to the adapter portion 201.

[0034] In these embodiments, the fixing portion 101 can be stably connected to the tripod base 4, thereby ensuring the stability of the connection between the accommodating portion 102 and the adapter portion 201, so that the stability of the level body 5 during installation and use is guaranteed.

[0035] In some embodiments of a semi-circular level stand, a mounting hole 103 communicating with the accommodating portion 102 is provided on the curved top member 1 , and the locking member 3 is threadedly mounted on the curved top member 1 through the mounting hole 103 .

[0036] In these embodiments, the mounting hole 103 is horizontally opened on the curved top member 1 and is connected to the accommodating portion 102. The thread on the inner wall of the mounting hole 103 cooperates with the thread of the locking member 3, so that the locking member 3 can stably extend into or out of the mounting hole 103, and can quickly and stably lock or release the locking adapter 201, making it simpler and more convenient to use.

[0037] In some embodiments of a semi-circular top level tripod, the locking member 3 includes a locking rod 301 and a locking plate 302 fixedly mounted on the locking rod 301. The locking rod 301 is threadedly mounted in the mounting hole 103. A pressing groove 104 is formed on the inner side wall of the mounting hole 103 corresponding to the accommodating portion 102. The locking plate 302 is movably mounted in the pressing groove 104. The locking plate 302 can be fitted on the adapter portion 201.

[0038] In these embodiments, the locking rod 301 is threadedly engaged with the mounting hole 103, and the locking plate 302 is rotated to move and abut against the adapter 201, thereby locking the adapter 201. The locking plate 302 is adapted to the outer surface of the adapter 201 to ensure that the adapter 201 can be firmly locked by the locking plate 302. Specifically, the press-fit groove 104 provides space for the locking plate 302 to move. The locking plate 302 is synchronously rotated and moved toward the adapter 201 by rotating the locking rod 301, and then abuts against and fixes the adapter 201 to secure the hinge member 2. It should be understood that the cooperation between the locking rod 301 and the locking plate 302 not only stably fixes the adapter 201 but also allows for quick unlocking, making it more flexible and convenient to use and facilitating flexible operation when adjusting the level body 5.

[0039] In some embodiments of a semicircular-top leveling instrument tripod, the adapter part 201 is spherical, the connecting part 202 is fixedly connected to the outer surface of the adapter part 201, the outer annular surface of the connecting part 202 is fixedly connected to the first flat seat 6, and the leveling instrument body 5 is seated on the first flat seat 6 through the connecting part 202.

[0040] In some embodiments of a semicircular top level tripod, the accommodating portion 102 is a ball groove formed on the top of the curved top member 1, the adapter portion 201 is ball-jointed in the ball groove, a clearance groove is formed at the top of the ball groove, and the connecting portion 202 extends out of the curved top member 1 through the clearance groove.

[0041] In these embodiments, Figure 3As shown, the first flat seat 6 is fixed on the connecting portion 202 and is adapted to the arc-shaped surface of the curved top member 1. It can not only stably place the level body 5, but also be adjusted at multiple angles to better meet the needs of use. Specifically, the fixing portion 101 is fixedly connected to the tripod seat 4 to stably fix the loading portion 102 on the tripod. Then the spherical adapter 201 is spherically hinged in the loading portion 102 adapted thereto. The connecting portion 202 is extended out of the curved top member 1 through the clearance groove to install the level body 5. Through the cooperation of the locking member 3 and the adapter 201, the adapter 201 is rotated, adjusted and fixed, thereby realizing the adjustment and fixation of the level body 5. It can be stably installed and is more convenient and flexible to use.

[0042] In order to further improve the flexibility of loading and unloading, in some embodiments of a semi-circular top level tripod, the adapter part 201 is spherical, and a second flat seat 7 is formed at the top of the adapter part 201. The connecting part 202 passes through the adapter part 201, and the level body 5 is seated on the second flat seat 7 through the connecting part 202.

[0043] In some embodiments of a semicircular level tripod, the accommodating portion 102 is a through slot running through the upper and lower ends of the curved top member 1 , the adapter portion 201 is spherically hinged in the through slot, and the connecting portion 202 passes through the curved top member 1 through the through slot.

[0044] In these embodiments, Figure 4 As shown, a through groove is formed in the middle of the arc-shaped curved surface of the curved top member 1, and a second flat seat 7 adapted to the level body 5 is formed on the top surface of the spherical adapter 201, and the connecting portion 202 passes through the adapter 201, and the connecting portion 202 and the adapter 201 are threadedly installed (not shown in the figure), and are installed with the level body 5 through the external thread at the top thereof, so that the level body 5 can be stably installed on the second flat seat 7 of the adapter 201, and then the adapter 201 is fixed to the curved top member 1 through the locking member 3. By providing a detachable connecting portion 202, loading and unloading are more flexible and convenient, and can be better adapted to different types of tripod seats 4.

[0045] It should be understood that the installation of a traditional level is achieved through the cooperation of the mounting holes (threaded connection) on its bottom surface and the mounting bolts. The above two technical implementation schemes are both suitable for this installation method, and can also use a solid or hollow tripod seat 4, providing a better choice for actual use.

[0046] In some embodiments of a leveling instrument tripod with a semicircular top, an outer annular surface at the top end of the connecting portion 202 is formed with a mounting thread that is compatible with the leveling instrument body 5 .

[0047] In these embodiments, the installation of the level body 5 can be better adapted by installing the threads, and the level body 5 can be ensured to be located on a plane to ensure stability in use.

[0048] In some embodiments of a semicircular-top level tripod, the tripod further includes a first leg 8 and a second leg 9. The first leg 8 is hinged to the lower surface of the tripod base 4, and the second leg 9 is fixed to the first leg 8 by a locking bolt.

[0049] In these embodiments, the first leg 8 is mounted under the tripod base 4 in a hinged manner to better adapt to use in different environments. A through hole is formed on the first leg 8, and a locking bolt is threadedly installed on the side of the through hole. The second leg 9 passes through the through hole and is fixed and adjusted by the locking bolt, which makes it easier and more flexible to use.

[0050] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
