Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a small prism support for total station layout. Background Technology

[0002] In total station layout operations, the pinion is a crucial signal reflection component, and its installation stability and positional adjustability directly determine measurement accuracy and operational efficiency. Traditional pinion supports often employ an integrated structure design, with the pinion fixedly connected to the support. When the pinion needs replacement due to lens wear, angular displacement, or damage after long-term use, the entire support must be disassembled and replaced. This not only increases equipment maintenance costs but also prolongs the interruption time of measurement operations, seriously affecting project progress.

[0003] Meanwhile, the installation and adjustment methods of traditional supports have significant limitations. Most supports are fixed in position only through fixing holes on a single mounting plate, making it impossible to flexibly adjust the height and angle of the small prism according to the on-site measurement environment. For example, in complex construction sites or road survey sites, if there are differences in elevation or obstacles obstructing the measurement points, traditional supports cannot be quickly adapted and adjusted. Workers need to build additional auxiliary supports or move the support positions multiple times, which is not only cumbersome but also prone to introducing measurement errors due to multiple adjustments, reducing the accuracy of the layout.

[0004] Therefore, it is necessary to provide a new type of small prism support for total station layout to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a small prism support for total station layout.

[0006] The total station layout prism support provided by this utility model includes a mounting plate, a through cavity is provided on the mounting plate, and a sleeve ring with a diameter larger than the through cavity is fixedly installed on the mounting plate. The sleeve ring is coaxially arranged with the through cavity, and two symmetrically distributed grooves are provided on the sleeve ring. The socket ring is fitted with a detachable mounting ring that is compatible with the socket ring, and a small prism is fixedly fitted inside the mounting ring. Two symmetrically distributed limiting protrusions are fixedly installed on the outer ring wall of the mounting ring, and positioning holes are provided on the limiting protrusions. The mounting plate is equipped with two sets of symmetrically distributed snap-fit ​​components. The snap-fit ​​components lock the limiting protrusions. Each snap-fit ​​component includes a mounting cylinder, which is fixedly mounted on the mounting plate and corresponds to the groove. The mounting cylinder is also elastically connected to a positioning rod. A sliding rod is fixedly installed on one side of the mounting plate, and an adjustment component for adjusting the angle and height of the mounting plate is installed on the sliding rod.

[0007] Preferably, a slidingly connected docking rod is inserted into the mounting cylinder, and one end of the docking rod extends out of the mounting cylinder and is fitted with a rotatably connected central connecting plate. The positioning rod is fixedly installed on the central connecting plate and is arranged parallel to the docking rod. The docking rod, the central connecting plate, and the positioning rod form a U-shaped structure.

[0008] Preferably, a spring is installed inside the mounting cylinder, one end of the spring is fixedly connected to the inner surface of the mounting cylinder, and the other end of the spring is fixedly connected to the insertion end of the connecting rod.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 6 This utility model provides a total station layout prism support, which includes a mounting plate 1, a sleeve ring 2, a mounting ring 3, a snap-fit ​​component 5, and an adjustment component 6.

[0018] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 Mounting plate 1 has mounting holes 1b at its corners and a through cavity 1a on its surface. A sleeve ring 2 with a diameter larger than the through cavity 1a is fixedly mounted on the mounting plate 1. The sleeve ring 2 is coaxially arranged with the through cavity 1a. Two symmetrically distributed grooves 2a are provided on the sleeve ring 2. A detachable mounting ring 3 that is compatible with the sleeve ring 2 is installed inside the sleeve ring 2. A small prism 4 is fixedly fitted inside the mounting ring 3. Two symmetrically distributed limiting protrusions 31 are fixedly mounted on the outer ring wall of the mounting ring 3. The limiting protrusions 31 have positioning holes 31a. The mounting plate 1 is equipped with two sets of symmetrically distributed snap-fit ​​components 5, which lock the limiting protrusion 31.

[0019] It should be noted that before installing the small prism 4 inside the socket ring 2, the limiting protrusion 31 on the mounting ring 3 should be aligned with the groove 2a. Then, the mounting ring 3 should be inserted into the socket ring 2 and abut against the mounting plate 1. The limiting protrusion 31 should be inserted into the groove 2a to prevent the mounting ring 3 from rotating inside the socket ring 2. Then, the locking component 5 should be used to lock the limiting protrusion 31, thereby completing the fixing of the mounting ring 3 with the small prism 4 inside the socket ring 2. Then, the operator can fix the mounting plate 1 in the appropriate position by passing screws through the mounting A hole 1b.

[0020] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The snap-fit ​​component 5 includes a mounting cylinder 51, which is fixedly mounted on the mounting plate 1 and corresponds to the groove 2a. The mounting cylinder 51 is elastically connected to a positioning rod 54. Specifically, a slidingly connected docking rod 52 is inserted into the mounting cylinder 51, and one end of the docking rod 52 extends out of the mounting cylinder 51 and is mounted with a rotatably connected central connecting plate 53. The positioning rod 54 is fixedly mounted on the central connecting plate 53 and is arranged parallel to the docking rod 52. The docking rod 52, the central connecting plate 53, and the positioning rod 54 form a U-shaped structure. A spring 55 is installed inside the mounting cylinder 51. One end of the spring 55 is fixedly connected to the inner cylinder surface of the mounting cylinder 51, and the other end of the spring 55 is fixedly connected to the insertion end of the docking rod 52.

[0021] It should be noted that: before installing the small prism 4 inside the sleeve ring 2, the connecting plate 53 is rotated in advance to drive the positioning rod 54 to be misaligned with the groove 2a. After the mounting ring 3 is installed inside the sleeve ring 2, the limiting protrusion 31 is inserted into the groove 2a. Then, the connecting plate 53 is pulled outward to make the connecting rod 52 slide outward along the mounting cylinder 51 and stretch the spring 55 until the positioning rod 54 is higher than the limiting protrusion 31. Then, the connecting plate 53 is rotated to drive the positioning rod 54 to correspond with the positioning hole 31a. Then, the connecting plate 53 is released. Therefore, the connecting rod 52 slides back along the mounting cylinder 51 under the action of the spring force of the spring 55. Thus, the positioning rod 54 is inserted into the positioning hole 31a, thereby locking the mounting ring 3. When it is necessary to replace the small prism 4, pull the connecting plate 53 to make the positioning rod 54 slide out of the positioning hole 31a, then deflect the connecting plate 53 to make the positioning rod 54 misalign with the groove 2a, and then release the connecting plate 53. Then, slide the mounting ring 3 outward to detach the mounting ring 3 from the sleeve ring 2.

[0022] Therefore, this application achieves quick fixing and disassembly of the small prism 4 by detachably engaging the mounting ring 3 and the sleeve ring 2, combined with the snap-fit ​​component 5. During installation, simply align the limiting protrusion 31 of the mounting ring 3 with the slot 2a of the sleeve ring 2 and insert it. Then, insert the positioning rod 54 of the snap-fit ​​component 5 into the positioning hole 31a of the limiting protrusion 31 to complete the fixing. During disassembly, pull the connecting plate 53 outward to disengage the positioning rod 54 from the positioning hole 31a, and the mounting ring 3 can be removed to replace the small prism 4. There is no need to disassemble the entire support, which greatly shortens the maintenance time and reduces the equipment replacement cost.

[0023] In addition, the spring 55 in this application is made of stainless steel or titanium alloy to improve corrosion resistance, and a polytetrafluoroethylene (PTFE) coating is applied to the surface of the spring 43 to enhance rust prevention.

[0024] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 A sliding rod 11 is fixedly installed on one side of the mounting plate 1, and an adjusting component 6 for adjusting the angle and height of the mounting plate 1 is installed on the sliding rod 11. The adjusting component 6 includes a sleeve 61, which is sleeved on the sliding rod 11. A threaded fastening screw 62 is inserted into a threaded through hole on the sleeve 61. A connecting plate 63 is fixedly installed on one side of the sleeve 61, and a fixing plate 64 is fixedly installed on the other end of the connecting plate 63. The fixing plate 64 has multiple evenly distributed mounting holes 64a.

[0025] It should be noted that when the mounting plate 1 cannot make the small prism 4 reach the appropriate position, the fixing plate 64 is fixed by passing the screw through the mounting hole B 64a. Then, the sliding rod 11 is inserted into the sleeve 61. The height of the small prism 4 can be adjusted by sliding the sliding rod 11 up and down along the sleeve 61. The angle of the small prism 4 can be adjusted by rotating the sliding rod 11. After the height and angle are adjusted, the fastening screw 62 is rotated to fix the sliding rod 11 on the sleeve 61.

[0026] Therefore, the mounting plate 1 and the adjustment component 6 in this application provide two independent installation methods, which can be flexibly selected according to the site environment to adapt to different terrains and measurement scenarios.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
