Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a quick-connect structure for surveying instruments. Background Technology

[0002] Surveying instruments are core tools in fields such as engineering surveying and geographical exploration, encompassing types such as total stations, levels, GPS receivers, and theodolites. Most surveying instruments require a support frame for stability during use.

[0003] For example, a portable surveying instrument mounting device with announcement number CN213930060U includes a tripod mounting base, with a surveying instrument mounting base located above the tripod mounting base; the surveying instrument mounting base has a mounting slot for placing the surveying instrument; multiple fastening mechanisms are fixedly connected to the surface of the surveying instrument mounting base near the mounting slot; each fastening mechanism includes a lead screw, a handwheel, a compression spring, a pressure plate, and a nut. This device solves the problem of the relatively complex structure of surveying instruments in existing mounting devices.

[0004] Most of the aforementioned existing technologies improve the overall structure. While the existing surveying instrument connection structure solves the problem of the complex structure of the surveying instrument in the existing mounting device, it still requires the simultaneous adjustment of multiple components to clamp the surveying instrument during actual use. This clamping method is cumbersome and can easily affect the efficiency of subsequent surveying. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect structure for surveying instruments, so as to solve the problem mentioned in the background art that the existing connection structure for surveying instruments is inconvenient for quick installation of surveying instruments during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect structure for surveying instruments, including a limiting component, a sliding pressing component slidably mounted inside the limiting component, and an adjustable clamping component slidably mounted on the outer surface of the limiting component; the sliding pressing component includes a placement platform, and the internal structure of the sliding pressing component cooperates with the internal structure of the limiting component to quickly clamp and limit the surveying instrument; the adjustable clamping component includes an extension block, and the internal structure of the adjustable clamping component is adjusted to accommodate surveying instruments of different sizes.

[0007] Furthermore, the limiting component includes a fixing plate, a support frame is fixedly installed below the fixing plate, and four limiting rods are fixedly installed on the outer surface of the support frame.

[0008] Furthermore, two brackets are fixedly installed on the outer surface of the fixing plate, and the same tray is fixedly installed below each of the two brackets, with a threaded ring fixedly installed below the tray.

[0009] Furthermore, a push rod is slidably installed inside the fixed plate, and a placement platform is fixedly installed above the push rod.

[0010] Furthermore, a limiting ring is fitted on the outer surface of the push rod, and a spring is fitted on the outer surface of the push rod. The upper part of the spring is connected to the lower part of the support frame, and the lower part is connected to the upper part of the limiting ring.

[0011] Furthermore, a connecting plate is sleeved on the outer surface of the limiting ring, and two fixed handles are fixedly installed on the outer surface of the connecting plate. Connecting brackets are fixedly installed at the four corners of the connecting plate, and a rotating column is rotatably installed above each connecting bracket.

[0012] Furthermore, four extension blocks are slidably mounted on the outer surface of the support frame, and a limit sleeve is fixedly installed below each extension block. Each limit sleeve is slidably mounted on the outer surface of the limit rod.

[0013] Furthermore, the lower part of each of the extension blocks is rotatably connected to the upper part of the rotating column, and the side end of each of the extension blocks is threaded with a bolt.

[0014] Furthermore, a clamping plate is slidably mounted above each of the extension blocks, and a fixing ring is fixedly mounted below each of the clamping plates, with each fixing ring connected to a bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This surveying instrument uses a quick-connect structure. The instrument presses down on the placement platform under its own weight, which in turn pushes the push rod and the limiting ring downwards. As the limiting ring moves, it causes the connecting plate and the connecting frame to slide. This, in turn, works with the rotating column to push the four extension blocks to slide toward the center of the fixed plate. As the extension blocks slide, they work with the top clamping plate to quickly clamp the surveying instrument. This allows the device to be quickly and precisely installed and positioned during use, thereby improving the efficiency of the device.

[0017] Furthermore, by removing the bolt from the side end of the extension block, then lifting the clamping plate upwards to pull the fixing ring out of the opening inside the extension block, and then adjusting the installation position of the clamping plate above the extension block according to the size of the surveying instrument, the clamping plate is then inserted into the corresponding groove along the fixing ring, and then the bolt is used for limiting. This allows the device to easily adjust the clamping distance according to the size of the surveying instrument during use, thereby improving the flexibility of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6A quick-connection structure for surveying instruments is disclosed to address the cumbersome connection issues when connecting existing surveying instruments to support legs. The structure includes a limiting component 1, with a sliding pressing component 2 slidably mounted inside the limiting component 1 and an adjustable clamping component 3 slidably mounted on the outer surface of the limiting component 1. The sliding pressing component 2 includes a placement platform 21, which, through cooperation with the internal structure of the limiting component 1, quickly clamps and limits the surveying instrument. The adjustable clamping component 3 includes an extension block 31, which, through adjustment of its internal structure, can accommodate surveying instruments of different sizes. The limiting component 1 includes a fixing plate 11, with a support frame 12 fixedly mounted below the fixing plate 11. The outer surface of the support frame 12 is fixed... Four limiting rods 13 are fixedly installed. Two brackets 14 are fixedly installed on the outer surface of the fixed plate 11. The same tray 15 is fixedly installed below each of the two brackets 14. A threaded ring 16 is fixedly installed below the tray 15. A push rod 22 is slidably installed inside the fixed plate 11. A placement platform 21 is fixedly installed above the push rod 22. A limiting ring 24 is sleeved on the outer surface of the push rod 22. A spring 23 is sleeved on the outer surface of the push rod 22. The upper part of the spring 23 is connected to the lower part of the support frame 12, and the lower part is connected to the upper part of the limiting ring 24. A connecting plate 25 is sleeved on the outer surface of the limiting ring 24. Two fixed handles 28 are fixedly installed on the outer surface of the connecting plate 25. Connecting brackets 26 are fixedly installed at the four corners of the connecting plate 25. A rotating column 27 is rotatably installed above each connecting bracket 26.

[0027] like Figure 1 - Figure 6 As shown, the user places the surveying instrument on the placement platform 21. The instrument presses down on the placement platform 21 with its weight, and the placement platform 21 pushes the push rod 22 to slide under the fixed plate 11. When the push rod 22 moves down, it will pull the spring 23 to extend. At the same time, the limiting ring 24 pushes the connecting plate 25 down. When the connecting plate 25 is pressed down, it can pull the rotating column 27 with the connecting frame 26. The rotating column 27 rotates and drives the upper extension block 31 to slide. The extension block 31 is limited by the limiting sleeve 32 and the limiting rod 13, thereby driving the clamping plate 35 installed on the upper part of the extension block 31 to move towards the center, thereby quickly clamping and limiting the surveying instrument placed on the placement platform 21. After clamping, the user can fix the device on the upper part of the support leg along the threaded ring 16. The device can quickly clamp the surveying instrument by relying on its own weight, thereby improving the clamping efficiency of the device.

[0028] Example 2: Figure 1 - Figure 6The technical solution shown, based on Embodiment 1, further discloses the following to address the problem that existing surveying instrument connection structures are inconvenient for adjusting the clamping range according to the size of the surveying instrument: four extension blocks 31 are slidably installed on the outer surface of the support frame 12, a limit sleeve 32 is fixedly installed below each extension block 31, each limit sleeve 32 is slidably installed on the outer surface of the limit rod 13, the lower part of each extension block 31 is rotatably connected to the upper part of the rotating column 27, a bolt 33 is threadedly installed on the side end of each extension block 31, a clamping plate 35 is slidably installed above each extension block 31, a fixing ring 34 is fixedly installed below each clamping plate 35, and each fixing ring 34 is connected to the bolt 33.

[0029] like Figure 1 - Figure 6 As shown, before use, the user presses down on the placement platform 21 to bring the clamping plate 35 together in advance. Then, the user observes and compares whether the size of the clamping plate 35 when gathered is smaller than the bottom of the surveying instrument. If the size of the clamping plate 35 when gathered is larger than the bottom of the surveying instrument, the user rotates the bolt 33 to pull the bolt 33 out of the extension block 31, and then slides the clamping plate 35 upwards. This allows the fixing ring 34 below the clamping plate 35 to be pulled out of the extension block 31. Then, the fixing ring 34 is adjusted along the groove on the upper part of the extension block 31 to make it closer to the fixing plate 11. Then, the fixing ring 34 is reinserted into the groove, and then the bolt 33 is inserted into the extension block 31 for installation. This allows the clamping distance to be freely adjusted during use, thereby improving the flexibility of the device.
