Description

Technical Field

[0001] This utility model relates to the field of architectural surveying technology, specifically a positioning device for an architectural surveying instrument. Background Technology

[0002] Architectural surveying is a fundamental technical task in the field of architectural engineering. It mainly uses surveying instruments and technical means to collect, process, analyze, and express spatial information related to architectural engineering, such as topography, landforms, building locations, and dimensions. This provides accurate data support for engineering planning, design, construction, operation, and management. It also establishes a unified horizontal and vertical control network within the survey area to provide benchmarks for subsequent measurements, ensuring the accuracy and consistency of measurement results at each stage.

[0003] In the field of architectural surveying, total stations are currently used for control surveying, construction layout, collection of topographic detail points, and deformation monitoring. However, in practice, total stations rely solely on tripods for support and positioning. This method of support and positioning may cause the tripod to tip over due to its high center of gravity in strong winds or under external impact, thus failing to provide adequate support and positioning. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that existing total stations rely solely on tripods for support and positioning, this method may cause the tripod to tip over due to its high center of gravity in strong winds or under external impact, thus failing to provide adequate support and positioning.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A positioning device for a building surveying instrument, characterized in that it comprises:

[0008] The support plate has an adjustment plate rotatably connected to its top, and an installation groove is provided on the outer wall of the support plate, with a support mechanism provided inside the installation groove.

[0009] The support mechanism includes a rotating frame, which is rotatably connected inside the mounting groove. A rotating shaft extends through the inside of the rotating frame. A sliding rod is slidably connected to the outside of the rotating frame, and a support rod extends through the inside of the sliding rod. A fixing sleeve is fitted around the outside of the support rod. A sliding plate is fixedly installed at the front end of the sliding rod, and a limit plate is fixedly installed at one end of the sliding plate inside the rotating frame. A fixing ring is fixedly installed at one end of the support rod.

[0010] As a further improvement of this utility model: a contact rod extends from the bottom end of the rotating frame, and a connecting rod is fixedly installed at one end of the contact rod that enters the rotating frame.

[0011] As a further embodiment of this utility model: the rotating frame forms a rotating structure between the rotating shaft and the bearing plate, and the rotating frame forms a sliding structure between the sliding plate and the sliding rod.

[0012] As a further embodiment of this utility model: the support rod and the sliding rod form a sliding structure, and the sliding rod is threadedly connected to the fixed sleeve.

[0013] As a further improvement of this utility model: the outer wall of the rotating frame is provided with a locking groove corresponding to the position of the sliding plate, and a reinforcing mechanism is provided inside the rotating frame.

[0014] As a further improvement of this utility model: the reinforcing mechanism includes a positioning hole, which is opened inside the sliding plate, and a through hole is opened on one side of the outer wall of the rotating frame, and a locking rod extends out of the through hole.

[0015] As a further embodiment of this utility model: a threaded column is fixedly installed at the bottom of the bearing plate, and a sliding sleeve is slidably connected to the outside of the threaded column, and a rotating groove is provided on the outside of the sliding sleeve.

[0016] As a further embodiment of this utility model: the sliding sleeve is threadedly connected to the threaded column, and the sliding sleeve and the fixed ring form a rotating structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of sliding rod, fixed sleeve, support rod, sliding plate and limiting plate, realizes adaptive extension and adjustment according to the unfolding of the rotating frame. At the same time, the threaded connection of the fixed sleeve can further improve the stability after unfolding, making the connection between the components of the positioning device stable and forming a whole. It can improve the overall resistance when encountering strong winds or external forces. In addition, the detachable effect of the abutment rod and connecting rod makes it easier to carry or transport.

[0019] 2. This utility model, through the design of positioning holes, locking rods, through holes, threaded columns, sliding sleeves, and rotating slots, avoids affecting the stability of the rotating frame when adjusting the position of the fixed ring. The threaded connection of the threaded column and the sliding sleeve improves the stability between them. The locking and limiting of the locking rod further enhances the stability and prevents the components from easily loosening, which could affect the accuracy of the measurement or cause the frame to tip over under external force.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 5 This is the first embodiment of the present utility model. This embodiment provides a positioning device for a building engineering surveying instrument, including: a support plate 1, an adjustment plate 2 rotatably connected to the top of the support plate 1, an installation groove 3 opened on the outer wall of the support plate 1, and a support mechanism 4 provided inside the installation groove 3;

[0031] The support mechanism 4 includes a rotating frame 401, which is rotatably connected inside the mounting groove 3. A rotating shaft 402 extends through the inside of the rotating frame 401. A sliding rod 403 is slidably connected to the outside of the rotating frame 401. A support rod 405 extends through the inside of the sliding rod 403. A fixing sleeve 404 is sleeved on the outside of the support rod 405. A sliding plate 406 is fixedly installed at the front end of the sliding rod 403. A limit plate 407 is fixedly installed at one end of the sliding plate 406 inside the rotating frame 401. A fixing ring 408 is fixedly installed at one end of the support rod 405.

[0032] Specifically, a contact rod 409 extends from the bottom of the rotating frame 401, and a connecting rod 410 is fixedly installed at one end of the contact rod 409 that enters the rotating frame 401.

[0033] Furthermore, the abutment rod 409 is threadedly connected to the rotating frame 401 via the connecting rod 410, thereby enabling the positioning device to be quickly assembled and disassembled, and multiple small parts can be detached for easy transport and carrying.

[0034] Specifically, the rotating frame 401 forms a rotating structure with the bearing disk 1 through the rotating shaft 402, and the rotating frame 401 forms a sliding structure with the sliding plate 406 and the sliding rod 403.

[0035] Furthermore, the rotating bearing 402 allows the support plate 1 and the rotating frame 401 to rotate, and the three rotating frames 401 form a conventional tripod support, which can support and position the total station.

[0036] Specifically, the support rod 405 and the sliding rod 403 form a sliding structure, and the sliding rod 403 is threadedly connected to the fixed sleeve 404.

[0037] Furthermore, the support rod 405 is axially inserted into the sliding rod 403 to form a telescopic structure, which can be adjusted according to the rotation of the rotating frame 401. It is threadedly connected to the sliding rod 403 and the support rod 405 through the fixed sleeve 404, which can play a positioning role after the rotating frame 401 is adjusted, thereby improving the support stability.

[0038] In use, the bearing plate 1 is first used to load and fix the total station instrument through the rotating adjustment plate 2 connected by rotation. It works with the rotating shaft 402 to allow the rotating frame 401 to rotate inside the mounting groove 3. At the same time, it is assembled with the connecting rod 410 and the abutment rod 409 to form a conventional tripod. The support rod 405 fixed by the fixing ring 408 forms a telescopic structure with the sliding rod 403, which can adaptively adjust with the rotation of the rotating frame 401. It slides along the rotating frame 401 through the cooperation of the sliding plate 406 and the limiting plate 407. Then, the fixing sleeve 404 is sleeved on the outside of the sliding rod 403 and the support rod 405 and threadedly connected, which can improve the connection stability after adjustment.

[0039] In summary, the sliding structure of the sliding rod 403 and the support rod 405 allows the length to be adaptively adjusted following the rotation of the rotating frame 401. Subsequently, the fixing sleeve 404 is fitted and threadedly connected to the sliding rod 403 and the support rod 405 to achieve a fixing effect, thereby positioning the rotating frame 401 and improving the stability and integrity of the connection between them. When encountering strong winds or external forces, it can provide a certain degree of stability. Furthermore, the detachable abutment rod 409 and connecting rod 410 allow the positioning device to be disassembled into multiple parts for easy carrying and transportation.

[0040] Example 2

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This is the second embodiment of the present invention, which provides an improved design of the positioning device for a building engineering surveying instrument.

[0042] Specifically, the outer wall of the rotating frame 401 is provided with a locking groove 5 corresponding to the position of the sliding plate 406, and the interior of the rotating frame 401 is provided with a reinforcing mechanism 6.

[0043] Furthermore, the sliding path of the sliding plate 406 is reserved through the locking groove 5, and the stability of the sliding process is improved.

[0044] Specifically, the reinforcement mechanism 6 includes a positioning hole 601, which is located inside the sliding plate 406. A through hole 603 is provided on one side of the outer wall of the rotating frame 401, and a locking rod 602 extends out of the through hole 603.

[0045] Furthermore, after the rotating frame 401 is fully extended, the sliding rod 403 and the support rod 405 slide through the sliding plate 406 to a position where they can no longer extend or to the corresponding position where the rotating frame 401 needs to be extended. Then, the locking rod 602 passes through the through hole 603 into the rotating frame 401 and is threadedly connected. At the same time, the locking rod 602 is inserted into the positioning hole 601 to further improve the stability between them.

[0046] Specifically, a threaded post 604 is fixedly installed at the bottom of the bearing plate 1, and a sliding sleeve 605 is slidably connected to the outside of the threaded post 604. A rotating groove 606 is opened on the outside of the sliding sleeve 605.

[0047] Furthermore, by connecting the sliding sleeve 605 to the threaded post 604, the fixed ring 408 can be adjusted to change position, so as to adjust the position of the sliding rod 403 and the support rod 405 according to the unfolding angle of the rotating frame 401, thereby improving the overall flexibility and applicability.

[0048] Specifically, the sliding sleeve 605 is threadedly connected to the threaded post 604, and the sliding sleeve 605 and the fixed ring 408 form a rotating structure.

[0049] Furthermore, by rotating the slot 606 to rotatably connect with the fixed ring 408, the fixed ring 408 is prevented from sliding along the threaded post 604 when the sliding sleeve 605 rotates and slides. This prevents the support rod 405 and the sliding plate 406 from being laterally limited by the rotating frame 401 and thus unable to be adjusted.

[0050] In use, first, according to the required unfolding angle of the rotating frame 401 on site, manually adjust the sliding sleeve 605 and rotate it along the threaded post 604. This allows the fixed ring 408 to drive the sliding rod 403 and the support rod 405 to adjust their positions through the rotating slot 606 until they reach a position where they can no longer extend. At the same time, insert and thread the locking rod 602 through the through hole 603. At this time, the locking rod 602 passes through the positioning hole 601 to limit the position, thereby further improving the overall stability of the positioning device connection and preventing loosening.

[0051] In summary, the threaded connection between the threaded post 604 and the sliding sleeve 605 provides initial stability while adjusting the positions of the sliding rod 403 and the support rod 405. Furthermore, the threaded connection between the locking rod 602 and the through hole 603, along with the insertion into the positioning hole 601, further enhances the stability of the connection. This ensures stable connections between the components of the positioning device, preventing loosening that could lead to wobbling during repositioning, affecting measurement accuracy, or even causing the device to tip over.
