Description

Technical Field

[0001] This utility model relates to the technical field of surveying equipment, and in particular to a surveying equipment that is easy to adjust the surveying height. Background Technology

[0002] Surveying equipment is widely used in surveying work. It consists of various instruments, tools, and related supporting devices designed to help obtain accurate geospatial information and complete various measurement tasks. It is usually composed of a support structure and a surveying instrument. The core function of the surveying instrument is to measure and collect relevant parameters of natural geographical elements and artificial facilities on the ground, such as measuring the undulation of the terrain, the spatial location and angle of buildings, and the length and direction of roads. It provides key data support for many aspects such as map drawing, engineering construction planning, and resource surveys.

[0003] In daily use, the tripod is inserted into the ground through the support, and then the surveying instrument is mounted on the support for surveying. However, while the surveying instrument is drop-resistant, its surveying end is generally sealed with glass. If it falls during use, it can easily damage the glass and may affect the normal progress of subsequent surveying work, resulting in economic losses. Furthermore, in daily use, when the ground is uneven, especially in areas with large terrain undulations such as mountains and hills, the height of the tripod legs cannot be adjusted accordingly, reducing its applicability. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a surveying device that facilitates adjustment of the surveying height.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a surveying device that facilitates adjustment of surveying height, including a connecting platform, a plurality of support legs rotatably fitted on the lower side of the connecting platform, an adjustment mechanism being provided on each of the plurality of support legs, a surveying instrument being fixedly connected to the upper side of the connecting platform, a protective box being fixedly connected to one side of the connecting platform, and a protective plate that cooperates with the surveying instrument being slidably fitted on the inner wall of the protective box.

[0006] The protective box is equipped with a reset component that cooperates with the protective plate. A trigger port is provided on one side of the protective box. A moving block is slidably fitted on the inner wall of the trigger port. A locking block is fixedly connected to the upper side of the moving block. A locking groove that cooperates with the locking block is provided on one side of the protective plate. A trigger mechanism is provided on one side of the moving block. A locking mechanism that cooperates with the reset component is provided on one side of the protective box.

[0007] By adopting the above technical solution, the adjustment mechanism includes an adjustment frame fixedly connected to a plurality of support legs, a support block slidably fitted on the inner wall of the plurality of adjustment frames, an adjustment port opened on the adjustment frame, a lead screw fixedly connected to the support block and slidably fitted with the adjustment port, and a nut ring threadedly fitted on the lead screw and abutting against the adjustment frame.

[0008] Furthermore, in order to adjust the overall height of the equipment and adapt it to different road surfaces.

[0009] By adopting the above technical solution, the reset assembly includes a reset port opened on one side of the protective box, a pull block that slides on the inner wall of the reset port and is fixedly connected to the protective plate, and a tension spring fixedly connected between the reset port and the pull block.

[0010] Furthermore, in order to facilitate the pulling and resetting of the pull block, the protective plate can be reset under special circumstances.

[0011] By adopting the above technical solution, the triggering mechanism includes a trigger plate rotatably fitted on one side of the moving block, an adjustment groove formed on the upper side of the trigger plate, a plug-in block that slides and elastically fits on the inner wall of the adjustment groove, and a limiting groove formed on one side of the moving block and cooperating with the plug-in block.

[0012] Furthermore, by engaging the plug and the limiting slot, the trigger plate can be fixed or flipped for use or storage.

[0013] By adopting the above technical solution, the locking mechanism includes a limiting plate fixedly connected to one side of the protective box, a locking port opened on one side of the limiting plate, a locking frame fixedly connected to one side of the pulling block, and a locking block that slides and elastically engages with the inner wall of the locking frame, wherein the locking block is inserted into the locking port.

[0014] Furthermore, when the pull block is reset, its locking block will insert into the locking slot to position the pull block and prevent it from wobbling back and forth.

[0015] By adopting the above technical solution, a soft pad is fixedly connected to the upper side of the plug block, and multiple anti-slip grooves are opened on the upper side of the soft pad.

[0016] Furthermore, the soft pads make it easier for personnel to wipe the plug-in blocks, and the anti-slip grooves increase the friction during operation.

[0017] By adopting the above technical solution, a lubrication groove is provided on one side of the locking block, and a roller is rotatably fitted on the inner wall of the lubrication groove.

[0018] Furthermore, when the locking block slides between the locking block and the limiting plate, its rollers rotate in the lubrication groove, reducing the friction between the locking block and the limiting plate.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, by setting up a protective plate and cooperating with a reset component, triggering mechanism and locking mechanism, when the equipment is accidentally tipped over, the triggering plate is subjected to impact force that can separate the locking block from the locking groove. Then, the tension spring pulls the protective plate to protect the glass end of the surveying instrument. This can reduce the damage to the surveying instrument caused by accident, reduce the impact of external factors on the surveying instrument, help extend the service life of the surveying instrument, and reduce the economic losses caused by instrument damage.

[0021] 2. In this application, the adjustment mechanism allows for convenient adjustment of the extension and retraction of the support legs through the cooperation of components such as the lead screw and nut ring, thereby enabling the adjustment of the height of the entire surveying equipment. This allows it to adapt well to different terrain undulations, such as mountains and hills, effectively broadening the applicability of the equipment and avoiding situations where uneven ground prevents the normal conduct of surveying work.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-6 As shown in the embodiment of this application, a surveying device that facilitates adjustment of the surveying height is disclosed, including a connecting platform 1. Multiple support legs 2 are rotatably fitted on the lower side of the connecting platform 1. Each of the multiple support legs 2 is provided with an adjustment mechanism 3. A surveying instrument 4 is fixedly connected to the upper side of the connecting platform 1. A protective box 5 is fixedly connected to one side of the connecting platform 1. A protective plate 6 that cooperates with the surveying instrument 4 is slidably fitted on the inner wall of the protective box 5.

[0031] like Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes an adjustment frame 301 fixedly connected to multiple support legs 2, a support block 302 slidably fitted on the inner wall of the multiple adjustment frames 301, an adjustment port 303 opened on the adjustment frame 301, a lead screw 304 fixedly connected to the support block 302 and slidably fitted with the adjustment port 303, and a nut ring 305 threadedly fitted on the lead screw 304 and abutting against the adjustment frame 301. By rotating the nut ring 305 to separate it from the adjustment frame 301, the support block 302 can be pushed to move freely, and then the lead screw 304 can be pressed between the adjustment frame 301 to achieve fixation. Thus, the height of the equipment can be adjusted according to different situations to make it suitable for different terrains.

[0032] The protective box 5 is provided with a reset component 7 that cooperates with the protective plate 6. A trigger port 8 is provided on one side of the protective box 5. A moving block 9 is slidably fitted on the inner wall of the trigger port 8. A locking block 10 is fixedly connected to the upper side of the moving block 9. A locking groove 11 that cooperates with the locking block 10 is provided on one side of the protective plate 6. A trigger mechanism 12 is provided on one side of the moving block 9. A locking mechanism 13 that cooperates with the reset component 7 is provided on one side of the protective box 5.

[0033] like Figure 3 and Figure 6 As shown, the reset assembly 7 includes a reset port 701 opened on one side of the protective box 5, a pull block 702 that slides in the inner wall of the reset port 701 and is fixedly connected to the protective plate 6, and a tension spring 703 that is fixedly connected between the reset port 701 and the pull block 702. When the protective plate 6 moves downward, its tension spring 703 is in a taut state. Once released, the tension spring 703 pulls the protective plate 6 upward to reset.

[0034] like Figure 5 As shown, the triggering mechanism 12 includes a trigger plate 121 rotatably fitted on one side of the moving block 9, an adjustment groove 122 opened on the upper side of the trigger plate 121, a plug block 123 slidingly and elastically fitted on the inner wall of the adjustment groove 122, and a limiting groove 124 opened on one side of the moving block 9 and cooperating with the plug block 123. After the plug block 123 inside the adjustment groove 122 is pushed into the limiting groove 124, the limiting plate 131 and the moving block 9 can be kept horizontal. When not in use, the trigger plate 121 can be flipped over and stored by adjusting the plug block 123 to separate from the limiting groove 124.

[0035] like Figure 5 As shown, a soft pad 14 is fixedly connected to the upper side of the plug block 123. Multiple anti-slip grooves 15 are provided on the upper side of the soft pad 14. When the plug block 123 needs to be moved, the presence of the soft pad 14 makes the touch more comfortable when the hand contacts the trigger plate 121, and the multiple anti-slip grooves 15 on the upper side improve the anti-slip performance.

[0036] like Figure 4 and Figure 6As shown, the locking mechanism 13 includes a limiting plate 131 fixedly connected to one side of the protective box 5, a locking opening 132 opened on one side of the limiting plate 131, a locking frame 133 fixedly connected to one side of the pulling block 702, and a locking block 134 that slides and elastically engages with the inner wall of the locking frame 133. The locking block 134 is inserted into the locking opening 132. When the tension spring 703 pulls the pulling block 702, its locking frame 133 will move upward with the pulling block 702. Since the locking block 134 is elastic and slides within the locking frame 133, when the locking block 134 overlaps with the locking opening 132, its locking block 134 instantly inserts into the locking opening 132, thereby fixing the protective plate 6 and preventing the tension spring 703 from pulling back and forth, ensuring that the protective plate 6 can protect the output end of the surveying instrument 4.

[0037] like Figure 4 As shown, a lubrication groove 16 is provided on one side of the locking block 134. A roller 17 is rotatably fitted on the inner wall of the lubrication groove 16. When the locking frame 133 moves up and down, the roller 17 inside the lubrication groove 16 can easily improve the lubrication between the locking block 134 and the limiting plate 131.

[0038] The operating principle of the surveying equipment that facilitates height adjustment in this embodiment is as follows: When it is necessary to adjust the height of the support leg 2, first operate the lead screw 304. Since the lead screw 304 and the nut ring 305 are threadedly connected, and the lead screw 304 is fixedly connected to the support block 302 and slides with the adjustment port 303 of the adjustment frame 301, rotate the nut ring 305. The nut ring 305 generates axial displacement relative to the lead screw 304, thereby pushing or pulling the support block 302 to slide on the inner wall of the adjustment frame 301. The movement of the support block 302 drives the support leg 2 to extend and retract, thereby realizing the adjustment of the height of the entire surveying equipment, enabling it to adapt to different terrain undulations, ensuring that the surveying instrument 4 is at a suitable working height, expanding the applicability of the equipment, and avoiding the problem of being unable to adjust the height due to uneven ground, which affects the surveying work.

[0039] In the initial state, the protective plate 6 is located inside the protective box 5. The tension spring 703 of the reset assembly 7 pulls the pulling block 702, keeping the protective plate 6 in a taut state. The locking block 10 is inserted into the locking groove 11. As the protective plate 6 is pulled upward and taut, the locking block 10 will block inside the locking groove 11. During use, if it is tilted, the trigger plate 121 will first contact the ground. Once the trigger plate 121 is subjected to pressure and impact, the moving block 9 will move inside the trigger port 8, thereby separating the locking block 10 from the locking groove 11. Once separated, the tension spring 703 will pull the pulling block 702 upward, causing the protective plate 6 to move upward to protect the glass end of the surveying instrument 4, reducing damage caused by accidents, reducing the impact of accidents on the surveying instrument 4, helping to extend the service life of the surveying instrument 4, and reducing economic losses caused by instrument damage.

[0040] When the tension spring 703 pulls the pulling block 702, its locking frame 133 will move upward with the pulling block 702. Since the locking block 134 is elastic and slides in the locking frame 133, when the locking block 134 and the locking port 132 overlap, the locking block 134 is instantly inserted into the locking port 132, thereby fixing the protective plate 6 and preventing the tension spring 703 from pulling back and forth, thus ensuring that the protective plate 6 can protect the output end of the surveying instrument 4.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
