TECHNICAL FIELD

[0001] The utility model relates to the technical field of geographical survey equipment, and concretely relates to a measuring device. BACKGROUND

[0002] Geographical measuring devices are instruments and devices for data collection, processing and output designed and manufactured for surveying and mapping operations, and have many classifications, including angle measurement, distance (slope distance, horizontal distance, height difference) measurement, three-dimensional coordinate measurement, traverse measurement, intersection point measurement and lofting measurement.

[0003] The Chinese invention patent with the publication number CN115854974B discloses a sight distance measuring device for surveying and mapping geography, which comprises a main body of a sight distance measuring device for surveying and mapping geography based on optical point taking, an outer cylinder and a buffer plate are installed on the main body, and a tripod, a mounting cylinder and a left side frame are further included. The main body is installed on the tripod, the tripod comprises a support frame, the main body is installed on the support frame through an adjusting structure, the bottom end of the support frame is installed with three support legs through three mounting bolts, and the three support legs can be adjusted in rotation relative to the support frame.

[0004] In actual use, the three support legs of the above measuring device will be inclined to press the ground to form a triangular structure to support the measuring main body due to the heavy weight of the measuring main body. The inclination angle of the three support legs is mainly limited by the limiting structure of the connecting joint. However, when the limiting structure of the connecting joint is damaged due to wear or hard contact collision after long-term use of the measuring device, it is difficult for the three support legs to maintain a stable support structure. When the user accidentally collides with the measuring device or the measuring environment is uneven, the surveying and mapping device is prone to falling and being damaged. UTILITY MODEL CONTENTS

[0005] Therefore, in order to solve the problem that the above measuring device relies only on the limiting structure of the connecting joint to maintain a stable support structure, and the limiting structure is prone to wear or damage due to hard contact, and the surveying and mapping device is prone to falling and being damaged, the utility model provides a measuring device, and the specific technical scheme is as follows:

[0012] Furthermore, the positioning component is a rubber component, which has a fitting part and a positioning part. The fitting part is fitted onto the end of the third support rod, and the positioning part has a conical structure.

[0013] Furthermore, the hinged rod assembly includes three connecting rods; one end of each connecting rod is hinged to the sliding cylinder, and the other end is hinged to the first hollow rod.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0040] like Figure 1 and Figure 2 As shown, a measuring device according to one embodiment of the present invention includes a measuring bracket 1 and a measuring main component 2. The measuring bracket 1 includes a supporting component 3 and a mounting component 4. The supporting component 3 includes a supporting base 31, three leg assemblies 32 hinged to the supporting base 31, a mounting sleeve 33 disposed at the bottom of the supporting base 31, a connecting rod unit 34 for connecting the three leg assemblies 32 to the mounting sleeve 33, and a spring-loaded buckle unit 35 disposed at the bottom of the mounting sleeve 33. The connecting rod unit 34 includes a sliding cylinder 341 slidably connected to the mounting sleeve 33, and hinged rod groups 34 respectively hinged to the three leg assemblies 32. 2; The spring-loaded unit 35 includes a limiting member 351 disposed at the bottom end of the mounting sleeve 33, a compression spring 352 sleeved on the mounting sleeve 33, and a fixing member 353. One end of the compression spring 352 presses against the support base 31, and the other end presses against the fixing member 353. The fixing member 353 is connected to the mounting sleeve 33 through a limiting structure 5. The limiting structure 5 is a threaded connection structure or a pin positioning structure. The mounting component 4 includes a mounting rod 41 sleeved in the mounting sleeve 33 and an adjustment component 42 disposed at the top of the mounting rod 41. The measuring main component 2 is disposed on the adjustment component 42.

[0041] When the aforementioned measuring device requires the support component 3 to perform a supporting action, the limiting structure 5 releases its limiting function. The compression spring 352 presses the fixing component 353 until the fixing component 353 contacts the sliding cylinder 341 and the sliding cylinder 341 contacts the limiting component 351. The hinge rod assembly 342 pushes the three support leg assemblies 32, causing the three support leg assemblies 32 to be in an unfolded state, thereby realizing the supporting function of the support component 3. At the same time, the fixing component 353 squeezes the compression spring 352, causing the sliding cylinder 341 to slide on the mounting sleeve 33, thereby causing the three support leg assemblies 32 to come closer to each other and be in a closed state.

[0042] In one embodiment, the limiting structure 5 is a threaded connection structure, the fixing member 353 is a threaded sleeve with internal threads, and the outer surface of the mounting sleeve 33 has an external thread portion. Specifically, the external thread portion is more than 15cm away from the limiting member 351 of the mounting sleeve 33. Thus, by threading the sleeve to the external thread portion, the fixing member 353 compresses the compression spring 352.

[0043] In one embodiment, the outer surface of the threaded sleeve is provided with a torsion plane. This torsion plane facilitates rotation of the threaded sleeve by the user.

[0044] like Figure 1 and Figure 2 , Figure 3 As shown, in one embodiment, the spring-loaded unit 35 further includes a second spring 354 sleeved on the mounting sleeve 33. The spring stiffness of the second spring 354 is less than that of the compression spring 352. One end of the second spring presses against the limiting member 351, and the other end presses against the sliding cylinder 341. Thus, since the spring stiffness of the second spring 354 is less than that of the compression spring 352, when the fixing member 353 is threadedly locked onto the sliding cylinder 341, the compression spring 352 can spring against the fixing member 353 to slide. At the same time, when the threaded sleeve limits and compresses the compression spring 352, the second spring 354 springs against the sliding cylinder 341, causing the sliding cylinder 341 to slide on the mounting sleeve 33, and the three support leg assemblies 32 are brought closer together by the force and are in a closed state.

[0045] like Figure 1 and Figure 4 As shown, in one embodiment, the outrigger assembly 32 includes a first hollow rod 321, a second hollow rod 322, and a third support rod 323. One end of the first hollow rod 321 is hinged to the support base 31, and the other end is provided with a first locking structure 328. One end of the second hollow rod 322 is sleeved inside the first hollow rod 321, and the other end is provided with a second locking structure 329. One end of the third support rod 323 is sleeved inside the second hollow rod 322, and the other end is provided with a positioning element 324 that contacts the ground. The first locking structure 328 is used to fix the position of the second hollow rod 322 relative to the first hollow rod 321, and the second locking structure 329 is used to fix the position of the third support rod 323 relative to the second hollow rod 322. Thus, the working height of the measuring main component 2 can be easily adjusted through the relative extension and retraction movement of the three support rods: the first hollow rod 321, the second hollow rod 322, and the third support rod 323.

[0046] In one embodiment, the positioning element 324 is a rubber element, which has a fitting portion 3241 and a positioning portion 3242. The fitting portion 3241 is fitted onto the end of the third support rod 323, and the positioning portion 3242 has a conical structure. This results in a large contact friction between the rubber element and the ground, ensuring the grip of the positioning element 324 and thus guaranteeing the operational stability of the surveying instrument.

[0047] In one embodiment, the hinge rod assembly 342 includes three connecting rods; one end of each connecting rod is hinged to the sliding cylinder 341, and the other end is hinged to the first hollow rod 321.

[0048] In one embodiment, the support member 3 further includes a locking screw 36 threaded onto the support base 31 for pressing against the mounting rod 41. Thus, by using the locking screw 36 to press against the mounting rod 41, the extension length of the mounting rod 41 can be adjusted.

[0049] like Figure 1 and Figure 5 As shown, in one embodiment, the adjustment assembly 42 includes a first rotation unit 401 and a second rotation unit 402, with the rotation center lines of the first rotation unit 401 and the second rotation unit 402 arranged perpendicularly. The first rotation unit 401 includes a first reference base 411 connected to the mounting rod 41, a first rotating seat 412 rotatably connected to the first reference base 411, and a first adjustment member 413 for fixing the first rotating seat 412 to the first reference base 411. The second rotation unit 402 includes a second reference base 421 connected to the first rotating seat 412, a second rotating seat 422 rotatably connected to the second reference base 421, and a second adjustment member 423 for fixing the second rotating seat 422 to the second reference base 421.

[0050] In one embodiment, the adjustment assembly 42 further includes a reference unit 403, which includes a mounting base 431 and four adjustment groups 432 connecting the mounting base 431 and the first reference base 411. Specifically, the four adjustment groups 432 are evenly arranged at the bottom of the first reference base 411. Each adjustment group 432 is a threaded connector with one end threaded to the mounting base 431 in a forward direction and the other end threaded to the first reference base 411 in a reverse direction. By rotating the four threaded connectors respectively, the height between the connection point of the mounting base 431 and the first reference base 411 is adjusted, thereby keeping the first reference base 411 in a horizontal state and ensuring the measurement effect.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
