Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping instruments, and specifically relates to an outdoor surveying and mapping positioning device. Background Art

[0002] Surveying and mapping instruments, to put it simply, are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output. They are various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction.

[0003] During the surveying process, the surveying instrument is installed on a bracket, and the bracket is placed on the ground to carry and position the surveying instrument. The bracket is based on the multiple degrees of freedom of the surveying instrument so as to adjust the position, angle, etc. of the surveying instrument relative to the bracket. Usually, the bracket is provided with a threaded fastener structure to lock the surveying instrument. When the surveying instrument needs to be adjusted relative to the bracket, the corresponding threaded fasteners are first loosened or unscrewed, and then the surveying instrument is moved or rotated relative to the bracket. After the adjustment is completed, the threaded fasteners are installed and tightened again.

[0004] However, repeatedly twisting the threaded fastener is relatively time-consuming, resulting in low adjustment efficiency, and easily causing the threaded fastener to be lost, making it inconvenient for users to use it. In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the technical problem of low adjustment efficiency, the basic concept of the technical solution adopted by the utility model is:

[0006] An outdoor surveying and positioning device comprises a support plate and a support frame rotatably connected to the bottom end of the outer wall of the support plate, a second adjustment and limiting mechanism is arranged at the top of the support plate, and a first adjustment and limiting mechanism is arranged above the second adjustment and limiting mechanism;

[0007] The first adjustment limit mechanism includes a fixed plate, the top of the fixed plate is provided with a sliding groove, the inner wall of the sliding groove is fixedly connected with a sliding rod, the outer wall of the sliding rod is slidably connected with a sliding block, the outer wall of the sliding block is fixedly connected with a supporting plate, the outer wall of the supporting plate is provided with a groove, the inner wall of the groove is provided with a rotating hole, the inner wall of the rotating hole is fixedly connected with a torsion spring, the torsion spring is fixedly connected with a rotating column at one end away from the rotating hole, the top of the outer wall of the rotating column is fixedly connected with a paddle, the bottom end of the outer wall of the rotating column is fixedly connected with a connecting rod, the outer wall of the connecting rod away from the rotating column is fixedly connected with a limiting block, the outer wall of the fixed plate is provided with a limiting groove, and the limiting block contacts and presses against the inner wall of the limiting groove.

[0008] According to the outdoor surveying and positioning device, the second adjustment and limiting mechanism includes a support column fixedly connected to the top of the support plate, the outer wall of the top of the support column is fixedly connected to a slip ring, the outer wall of the slip ring is slidably connected to a rotating frame, the upper end of the rotating frame is connected to a fixed plate, the inner wall of the rotating frame is provided with a rotating groove, the outer wall of the slip ring is slidably connected to the inner wall of the rotating groove, the outer wall of the support column is provided with a positioning hole, the outer wall of the rotating frame is fixedly connected to a fixed block, the outer wall of the fixed block is provided with a through hole, the inner wall of the through hole is slidably connected to a sliding column, one end of the sliding column is fixedly connected to a card protrusion, the end of the sliding column away from the card protrusion is fixedly connected to a circular plate, the end of the circular plate close to the sliding column is fixedly connected to a spring, the end of the spring away from the circular plate is fixedly connected to the outer wall of the fixed block, and the card protrusion is snap-connected to the inner wall of the positioning hole.

[0009] According to the outdoor surveying and positioning device, the number of the support plates and the number of the limit blocks are both two, and the support plates and the limit blocks are symmetrically distributed on the left and right sides of the sliding block.

[0010] According to the outdoor surveying and positioning device, the limiting block is made of rubber.

[0011] According to the outdoor surveying and positioning device, there are a plurality of positioning holes, and the positioning holes are evenly and equidistantly distributed on the outer wall of the support column.

[0012] According to the outdoor surveying and positioning device, the outer wall of the card protrusion is in an arc shape, and the outer wall of the card protrusion fits closely with the inner wall of the positioning hole.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the above structure, the support plate can be installed with a surveying instrument (such as a level, etc.). When it needs to be moved and adjusted, the paddle will drive the rotating column to rotate, and the rotating column will drive the connecting rod at the bottom to rotate, and the connecting rod will drive the limit block to rotate in the direction away from the limit groove, so that the outer wall of the limit block will release the friction limit between the limit groove and the limit groove. At this time, the surveying instrument can be pulled to move, so as to adjust the position of the surveying instrument. When it is adjusted to a suitable position, the paddle can be released, and the torsion spring can rebound and rotate at this time, driving the rotating column to reset and move, so that the outer wall of the limit block is in contact and extruded with the limit groove again, forming a friction limit effect, thereby completing the limit effect on the surveying instrument.

[0015] When rotation adjustment is required, rotate the fixed plate to drive the rotating frame to rotate on the outer wall of the support column. When the rotating frame is rotating, it can drive the fixed block to rotate, thereby driving the sliding column and the card protrusion to rotate. When the card protrusion rotates, it will be squeezed by the inner wall of the positioning hole. The card protrusion drives the sliding column to move outward, and at the same time drives the circular plate to move to stretch the spring until the card protrusion completely detaches from the inner wall of the positioning hole. When the rotating frame continues to be rotated to drive the sliding column and the card protrusion to move to the next positioning hole, the spring rebounds and pushes the card protrusion to engage with the inner wall of the positioning hole. In this way, the frame is continuously rotated until the angle of the surveying instrument is adjusted to a suitable position.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1 to 5An outdoor surveying and positioning device comprises a support plate 1, a support frame 2 rotatably connected to the bottom end of the outer wall of the support plate 1, a second adjustment and limiting mechanism 32 is arranged at the top of the support plate 1, a first adjustment and limiting mechanism 31 is arranged above the second adjustment and limiting mechanism 32, the first adjustment and limiting mechanism 31 comprises a fixed plate 311, a slide groove is provided at the top of the fixed plate 311, a slide rod 312 is fixedly connected to the inner wall of the slide groove, a slider 313 is slidably connected to the outer wall of the slider 312, a surveying instrument 314 is installed at the top of the slider 313, a support plate 315 is fixedly connected to the outer wall of the slider 313, and the support plate 315 The top is used to install a surveying instrument 314 (such as a level, etc.), a groove is provided on the outer wall of the support plate 315, a rotating hole is provided on the inner wall of the groove, a torsion spring 316 is fixedly connected to the inner wall of the rotating hole, a rotating column 317 is fixedly connected to the end of the torsion spring 316 away from the rotating hole, a paddle 318 is fixedly connected to the top end of the outer wall of the rotating column 317, a connecting rod 319 is fixedly connected to the bottom end of the outer wall of the rotating column 317, and a limiting block 3110 is fixedly connected to the outer wall of the end of the connecting rod 319 away from the rotating column 317. A limiting groove 3111 is provided on the outer wall of the fixing plate 311, and the limiting block 3110 contacts and presses against the inner wall of the limiting groove 3111.

[0026] Furthermore, there are two support plates 315 and two limit blocks 3110, which are symmetrically distributed on the left and right sides of the slider 313, so that the left and right sides of the fixed plate 311 can be simultaneously limited and supported, thereby increasing the stability of the fixed plate 311 after position adjustment.

[0027] Furthermore, the inner wall of the limiting groove 3111 is fitted closely to the outer wall of the limiting block 3110, and the limiting block 3110 is made of rubber material, so that the outer wall of the limiting block 3110 can be pushed tightly against the inner wall of the limiting groove 3111 through the elastic extrusion of the torsion spring 316, thereby limiting the fixing plate 311 through friction.

[0028] The second adjustment and limiting mechanism 32 includes a support column 321 fixedly connected to the top of the support plate 1, a slip ring 322 fixedly connected to the outer wall of the top of the support column 321, a rotating frame 323 slidably connected to the outer wall of the slip ring 322, a rotating groove 324 is provided on the inner wall of the rotating frame 323, the outer wall of the slip ring 322 is slidably connected to the inner wall of the rotating groove 324, a positioning hole 325 is provided on the outer wall of the support column 321, a fixed block 326 is fixedly connected to the outer wall of the rotating frame 323, and a fixed hole 325 is provided on the outer wall of the support column 321. A through hole is provided on the outer wall of the fixed block 326, and a sliding column 327 is slidably connected to the inner wall of the through hole. A locking protrusion 328 is fixedly connected to one end of the sliding column 327, and a circular plate 329 is fixedly connected to the end of the sliding column 327 away from the locking protrusion 328. A spring 3210 is fixedly connected to the end of the circular plate 329 close to the sliding column 327. The end of the spring 3210 away from the circular plate 329 is fixedly connected to the outer wall of the fixed block 326, and the locking protrusion 328 is snap-connected to the inner wall of the positioning hole 325.

[0029] Furthermore, there are a plurality of positioning holes 325 , which are evenly and equidistantly distributed on the outer wall of the support column 321 , so that the surveying instrument 314 can be rotated and adjusted at multiple angles.

[0030] Furthermore, the outer wall of the card protrusion 328 is an arc-shaped surface, and the outer wall of the card protrusion 328 fits closely with the inner wall of the positioning hole 325, so as to ensure the stability of the card connection. At the same time, when the card protrusion 328 is rotating, it can also be squeezed by the positioning hole 325, so as to facilitate the adjustment of the angle of the surveying instrument 314.

[0031] The implementation principle of an outdoor surveying and positioning device of this embodiment is as follows: when it is necessary to fine-tune the position of the surveying instrument 314, the paddle 318 can be toggled in the direction of the surveying instrument 314, and the paddle 318 will drive the rotating column 317 to rotate. When the rotating column 317 rotates, the torsion spring 316 can be driven to rotate, and at the same time, the rotating column 317 will drive the connecting rod 319 at the bottom to rotate, and the connecting rod 319 will drive the limit block 3110 to rotate in the direction away from the limit groove 3111, so that the outer wall of the limit block 3110 will contact the friction between the limit groove 3111 and the limit groove 3111. The surveying instrument 314 can be pulled left and right to move. When the surveying instrument 314 moves, the slider 313 will be driven to move on the outer wall of the slider 312, so as to adjust the position of the surveying instrument 314. When it is adjusted to a suitable position, the paddle 318 can be released, and the torsion spring 316 can rebound and rotate at this time, driving the rotating column 317 to reset and move, thereby driving the connecting rod 319 and the limit block 3110 to rotate, so that the outer wall of the limit block 3110 is contacted and extruded with the limit groove 3111 again, forming a friction limit effect, and completing the limit effect on the surveying instrument 314.

[0032] When the angle of the surveying instrument 314 needs to be rotated and adjusted, the fixing plate 311 is directly rotated. At this time, the fixing plate 311 will drive the rotating frame 323 to rotate on the outer wall of the support column 321. When the rotating frame 323 rotates, the fixing block 326 can be driven to rotate, thereby driving the sliding column 327 and the card protrusion 328 to rotate. When the card protrusion 328 rotates, it will be squeezed by the inner wall of the positioning hole 325, so that the card protrusion 328 drives the sliding column 327 to move outward, and at the same time drives the circular plate 329 to move to stretch the spring 3210 until the card protrusion 328 is completely separated from the inner wall of the positioning hole 325. When the rotating frame 323 continues to be rotated to drive the sliding column 327 and the card protrusion 328 to move to the next positioning hole 325, the spring 3210 rebounds and pushes the card protrusion 328 to be connected to the inner wall of the positioning hole 325. In this way, the frame 323 is continuously rotated until the angle of the surveying instrument 314 is adjusted to a suitable position.
