Description

Technical Field

[0001] This utility model relates to the technical field of field surveying and mapping, and in particular to a field terminal fixing mechanism and field surveying and mapping equipment. Background Technology

[0002] Mobile surveying and field investigation terminals are portable devices used for field data collection, measurement, and positioning. They have functions such as high-precision positioning, data collection and processing, and map navigation. In the field operation environment, the stable installation of field terminal equipment is crucial.

[0003] In fields such as geological exploration, environmental monitoring, and construction engineering, the diversity of work locations and monitoring objects requires field terminals to be able to flexibly adapt to various angles and heights, and to be able to be quickly deployed and adjusted while ensuring stability. Traditional field terminal fixing mechanisms usually adopt simple support structures, which have poor adjustment flexibility and are difficult to adapt to complex and changing terrain conditions.

[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 4 As shown;

[0042] A field terminal fixing mechanism according to an embodiment of this utility model includes:

[0043] The mounting base 1 has at least three support mechanisms 2 at equal angles at its bottom end. The support mechanisms 2 are key components for achieving stable support of the mounting base 1.

[0044] Mounting post 3 is installed inside the shaft hole of mounting base 1. Support shaft 4 is slidably installed in the shaft cavity of mounting post 3 along the length direction. Support shaft 4 can rotate freely in the shaft cavity of mounting post 3 to realize free adjustment of the height and angle of support shaft. Support shaft 4 and mounting post 3 are fixed by locking member.

[0045] The extension shaft 5 is slidably connected to the inner groove of the support shaft 4 through a connector. The extension shaft 5 is provided with a long keyway. The extension shaft 5 rotates around the axis of the connector. The extension shaft 5 is a functional component that realizes secondary extension and angle adjustment. The extension shaft 5 and the support shaft 4 are locked together through the connector.

[0046] The mounting mechanism 6 is rotatably mounted in the shaft hole at the end of the extension shaft 5 via a threaded column. A fixing component is mounted on the threaded column. The mounting mechanism 6 is used for installation of field terminals.

[0047] By adopting the above technical solution, at least three support mechanisms 2 set at equal angles at the bottom of the mounting base 1 can provide a stable support foundation for the entire device, effectively preventing the mounting base 1 from tilting or falling over in complex terrain in the field. The mounting column 3 is installed in the shaft hole of the mounting base 1, and the support shaft 4, which slides and rotates freely in its shaft cavity, is used with locking parts to achieve free adjustment and fixation of height and angle. The position of the support shaft 4 can be flexibly adjusted according to the operation requirements. The extension shaft 5 is slidably connected to the inner groove of the support shaft 4 through the connector and can rotate around the axis of the connector. With the help of the long keyway, it can achieve secondary extension and angle adjustment, further expanding the installation range and angle adjustment space of the field terminal. At the same time, it is used to realize the eccentric position of the field terminal and the axis of the mounting base 1. The locking function of the connector ensures that the position is fixed after adjustment. The installation mechanism 6 is rotatably installed in the shaft hole at the end of the extension shaft 5 through the threaded column. With the help of the fixing parts on the threaded column, it can achieve fine adjustment of the installation angle of the field terminal and firmly fix the terminal to prevent loosening during operation. It can realize the flexible installation of the field terminal in complex field environments and adapt to diverse field operation requirements.

[0048] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the support mechanism 2 includes:

[0049] Mounting component 21 is mounted on mounting base 1, and connecting shaft 22 is rotatably mounted on mounting component 21;

[0050] A fixed shaft 23 is installed inside the shaft cavity of the connecting shaft 22. An assembly 24 is provided on the fixed shaft 23, and a guide rod 25 is provided on the assembly 24.

[0051] Adjustment mechanism 26 is installed on guide rod 25. Adjustment mechanism 26 is used to level the support of mounting base 1. A connecting mechanism 27 is provided at the end of adjustment mechanism 26.

[0052] The transmission mechanism 28 is mounted on the mounting column 3 and is used for the synchronous rotation of multiple support mechanisms 2.

[0053] In this embodiment, the mounting component 21 is installed on the mounting base 1, providing a stable rotational foundation for the connecting shaft 22. The fixed shaft 23 is installed inside the shaft cavity of the connecting shaft 22. The assembly component 24 provided therein provides a reliable mounting carrier for the guide rod 25. At the same time, the rotation of the assembly component 24 causes the support mechanism 2 to open and close. The guide rod 25 provides a sliding guide for the adjustment mechanism 26, ensuring that the adjustment mechanism 26 moves smoothly in a preset direction to achieve the adjustment of the support height. At the same time, the mounting base 1 is leveled to solve the problem of the mounting base 1 tilting due to uneven terrain in the field. The connecting mechanism 27 at the end of the adjustment mechanism 26 is used to increase the connection strength with the ground and enhance the stable contact between the support mechanism 2 and the ground.

[0054] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the transmission mechanism 28 includes:

[0055] The movable part 28a is slidably mounted on the mounting column 3 along the length direction of the mounting column 3. Multiple straight racks 28b are set at equal angles on the movable part 28a. The number and position of the straight racks 28b correspond one-to-one with the fixed shaft 23.

[0056] The transmission gear 28c is coaxially mounted on the fixed shaft 23, and the spur rack 28b meshes with the transmission gear 28c.

[0057] The mounting column 3 is provided with a baffle 28d, which is used to limit the movement range of the moving part 28a;

[0058] In this embodiment, the movable component 28a is slidably installed along the length of the mounting column 3. Multiple racks 28b arranged at equal angles on it correspond one-to-one in number and position to the fixed shafts 23. They are engaged with the transmission gears 28c mounted coaxially with the fixed shafts 23. When the movable component 28a slides, the meshing of the racks 28b and the transmission gears 28c can synchronously drive all the fixed shafts 23 to rotate, realizing the synchronous unfolding or retraction of multiple support mechanisms 2 without the need for individual adjustments, greatly simplifying the operation process and ensuring that the unfolding angle of each support mechanism 2 is consistent. The baffle 28d on the mounting column 3 limits the movement range of the movable component 28a, preventing the movable component 28a from sliding excessively, which could cause the racks 28b and the transmission gears 28c to disengage or the support mechanism 2 to rotate too much and become unstable, thus improving the ease of operation of the support mechanism 2.

[0059] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the adjustment mechanism 26 includes:

[0060] The extension leg 26a is slidably mounted on the guide rod 25. A transmission element 26b is provided on the extension leg 26a. A locking element 26c is provided on one side of the transmission element 26b, and a flipping element 26d is rotatably mounted on the other side. An eccentric circular structure is provided at the sliding connection end between the flipping element 26d and the extension leg 26a.

[0061] Stabilizer 26e is installed at the end of guide rod 25, and extension leg 26a is slidably installed inside stabilizer 26e;

[0062] In this embodiment, the extension leg 26a is slidably mounted on the guide rod 25. Together with the stabilizing member 26e mounted on the end of the guide rod 25, it provides dual guidance and support for the sliding of the extension leg 26a, ensuring smooth linear movement to precisely adjust the support height. A locking member 26c on one side of the transmission member 26b on the extension leg 26a can lock it to the guide rod 25 after the extension leg 26a is adjusted to the target height, preventing height deviation due to external forces during support. A rotating flip member 26d, rotatably mounted on the other side of the transmission member 26b, has an eccentric circular structure at its slidable connection end with the extension leg 26a. When the flip member 26d rotates, it can lock or unlock the connection between the locking member 26c and the guide rod 25 through eccentric action, achieving height adjustment to suit the leveling needs of undulating terrain in the field. This can be accomplished without complex tools, enhancing the practicality of the field terminal fixing mechanism.

[0063] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the connecting mechanism 27 includes:

[0064] The auxiliary component 27a is fixed to the end of the extension leg 26a by bolts.

[0065] Ground stake 27b is fixedly installed on auxiliary component 27a;

[0066] A pedal 27c is installed on the auxiliary component 27a, and a stiffener is provided at the connection between the pedal 27c and the auxiliary component 27a.

[0067] In this embodiment, the auxiliary component 27a is fixed to the end of the extension leg 26a by bolts. The bolt connection ensures that the auxiliary component 27a and the extension leg 26a are firmly connected and also has detachability. The ground stake 27b fixedly installed on the auxiliary component 27a can be inserted into the soil in soft ground environment, which greatly enhances the grip of the support mechanism 2 on the ground and ensures the stability of the mounting base 1 and the field terminal. The pedal 27c installed on the auxiliary component 27a provides the operator with a force application point. By stepping on the pedal 27c, the ground stake 27b can be easily pressed into the ground without the need for additional tools, which improves the convenience of operation. In addition, the stiffening plate at the connection between the pedal 27c and the auxiliary component 27a can enhance the structural strength of the connection between the two.

[0068] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the mounting mechanism 6 includes:

[0069] A fixed base 61 is mounted on a threaded column, and clamping parts 62 are slidably mounted on both ends of the fixed base 61.

[0070] Spring 63 has two ends that are respectively connected to two clamping parts 62;

[0071] In this embodiment, the fixing base 61 is installed on the threaded column, which not only provides a stable installation base for the clamping member 62, but also allows for flexible adjustment of the installation angle of the field terminal as the threaded column rotates, adapting to different observation direction requirements. The clamping members 62, which are slidably installed at both ends of the fixing base 61, cooperate with the springs 63 connected to the two clamping members 62 at both ends. The elastic force of the springs 63 can automatically adapt to field terminals of different sizes. The clamping members 62 can be quickly clamped by adjusting the distance through sliding, and the terminal can be fixed without additional tools, improving the efficiency of field operations.

[0072] The field terminal fixing mechanism of this utility model can be used for various types of field surveying equipment;

[0073] Compared with existing field surveying equipment, the field terminal fixing mechanism of this utility model has at least three support mechanisms 2 at the bottom of the mounting base 1, which makes it easier to achieve stable support and precise leveling in complex field terrain. With the help of the transmission mechanism 28, multiple support mechanisms 2 can be deployed and stored simultaneously. With the help of the mounting mechanism 6, it can automatically adapt to terminals of different sizes and clamp quickly. Compared with existing equipment, it is more efficient in operation and significantly reduces the time spent in field operations. The extension shaft 5 realizes secondary extension and angle adjustment. With the elastic clamping of the mounting mechanism 6, it can adapt to more types of field terminals and diversified operation scenarios compared with existing equipment, and its flexibility is significantly improved.

[0074] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
