[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The bracket and the surveying instrument are set as a whole. When surveying is required, the foot assembly is moved down, the plug plate is inserted into the slide slot, and multiple foot assemblies are rotated to form a support frame for supporting the surveying instrument. When surveying is not required, multiple foot assemblies are moved up, and the lower limit assembly will limit and fix the foot assemblies. Multiple foot assemblies form a protective frame surrounding the surveying instrument, which not only provides protection for the surveying instrument, but also reduces the volume of the entire surveying equipment, making it convenient to carry and transfer the surveying instrument.

[0023] When the support leg assembly moves upward to form a protective frame, in order to prevent the support leg assembly from moving downward during the movement, the push bead will squeeze the push ring, thereby pushing the push tube out of the wire hole.

[0024] In order to prevent multiple control ropes from getting entangled with each other during use, the middle part of the control rope is set as an elastic spiral to ensure that the control rope can be automatically and completely coiled when not in use, which saves space and ensures that multiple control ropes do not touch each other, thus avoiding entanglement;

[0025] The downward moving control rope drives the locking plate to move downward, so that the fixed teeth on the locking plate engage with the latching teeth on the rotating shaft, thereby fixing the position of the rotating shaft. When impacted, the counterweight structure will also pull the control rope due to inertia, thereby strengthening the locking effect of the locking plate on the rotating shaft.

[0026] The counterweight is lowered and the control rope limits the position of the counterweight, so that the overall center of gravity of the equipment moves downward, improving the stability of the equipment. At the same time, the suspended counterweight can automatically adjust the center of gravity of the equipment set on different terrains;

[0027] The positions of the cardboard and the pedal are fixed and restricted by the notches and protrusions. The elastic cardboard can be quickly installed and removed elastically, ensuring portability.

[0028] The control rope plays different roles in the process of the support leg assembly moving up and down. When the support leg assembly moves up, the control rope controls the pushing bead, which needs to play the role of linking the pushing tube and fixing the support leg assembly. After the support leg assembly moves down, the control rope is used for the counterweight block below and locks the rotating shaft at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0043] Reference Figure 1-Figure 11 , a construction engineering cost on-site convenient adjustment surveying and mapping equipment, comprising: a surveying and mapping instrument 1 and a base plate 2, the side plate 10 of the base plate 2 is annularly provided with three slide grooves, the slide groove notches are arranged on the side of the base plate 2, and three displacement components 3 are respectively arranged inside the three slide grooves;

[0044] The displacement assembly 3 includes a draw plate 31 and a pull plate 32. The draw plate 31 is limitedly slidably arranged inside the slide groove. A bayonet is provided inside the draw plate 31. The pull plate 32 is L-shaped, and the vertical end is clamped inside the bayonet.

[0045] A support leg assembly 4 is disposed inside the vertical end of the pull plate 32 , wherein the width of the support leg is smaller than the width of the bayonet, and the support leg assembly 4 is used to support the surveying instrument 1 ;

[0046] A limit assembly 5 is provided inside the pull plate 32, and the limit assembly 5 is used to limit the position of the displacement assembly 3. The limit assembly 5 includes a control rope 51. A wire hole 8 is provided at the bottom side of the bottom plate 2. One end of the control rope 51 is connected to the pull plate 32, and the other end passes through the wire hole 8.

[0047] A counterweight structure 6 is disposed in the middle of the bottom surface of the bottom plate 2 . The counterweight structure 6 is fixedly connected to the bottom end of the control rope 51 and is used to drive the control rope 51 to move.

[0048] In the embodiment of the application of the above technical solution, the existing surveying instrument 1 and the bracket are mostly separately arranged. During the transfer process, they need to be disassembled and then transferred separately. The present invention sets the bracket and the surveying instrument 1 as a whole. When surveying is required, the support leg assembly 4 is moved down, the drawer 31 is inserted into the slide groove, and the multiple support leg assemblies 4 are rotated to form a support frame for supporting the surveying instrument 1. When surveying is not required, the multiple support leg assemblies 4 are moved up, and the lower limit assembly 5 will limit and fix the support leg assembly 4. The multiple support leg assemblies 4 form a protective frame surrounding the surveying instrument 1. While providing protection for the surveying instrument 1, the volume of the entire surveying equipment is reduced, which facilitates the carrying and transfer of the surveying instrument 1.

[0049] The preferred technical solution in this embodiment is:

[0050] Reference Figure 1-4 The support leg assembly 4 includes a rotating shaft 41, a telescopic support rod 42, a ground nail 43 and a pedal 44. A rotating opening is opened inside the pull plate 32, and the rotating shaft 41 is rotatably installed inside the rotating opening. The telescopic support rod 42 is fixedly connected to the bottom surface of the rotating shaft 41, and the ground nail 43 is threadedly installed at the bottom of the telescopic support rod 42. The pedal 44 is fixedly connected to the bottom of the telescopic support rod 42 on one side close to the bottom plate 2.

[0051] When the surveying instrument 1 needs to be supported, the pull plate 32 is moved downward, the pull plate 32 is clamped in the bayonet, and the plug plate is pushed into the slide slot to fix the position of the pull plate 32, so as to ensure that the support leg assembly 4 does not move up and down;

[0052] During surveying and mapping, the rotating shaft 41 can drive the telescopic support rod 42 to rotate outward, so that the multiple telescopic support rods 42 form a triangular support frame with high stability. The telescopic support rod 42 can quickly adjust the length and can be quickly adjusted according to the terrain. It is suitable for surveying and mapping under various terrains. At the same time, in order to strengthen the fixation of the telescopic support rod 42 to the ground during use, the ground nail 43 can be selectively used according to the use environment. When the ground nail 43 is needed, the ground nail 43 is moved out from the bottom of the telescopic support rod 42 by rotating the ground nail 43, and the ground nail 43 can be quickly nailed into the ground by stepping on the pedal 44 to complete the deployment and support of the support leg assembly 4.

[0053] Reference Figure 5 The limit assembly 5 further includes a push tube 52, a clamping plate 53 and a push bead 54. The clamping plate 53 is fixedly connected to a side of the push tube 52 close to the pull plate 32 and is used to clamp the position of the pedal 44. The push tube 52 is slidably arranged inside the wire hole 8, and a push ring is arranged at one end away from the pull plate 32. The push bead 54 is fixedly connected to the control rope 51 and is used to drive the push tube 52 to move.

[0054] The control rope 51 is divided into an elastic spiral portion 511 and two straightened portions 512 . The two straightened portions 512 are fixedly connected to both ends of the elastic spiral portion 511 , and the two straightened portions 512 are fixedly connected to the locking plate 71 and the counterweight block 62 , respectively.

[0055] The limit assembly 5 is mainly used to limit the position of the foot assembly 4. When the foot assembly 4 moves up to form a protective frame, in order to prevent the foot assembly 4 from moving downward during the movement, the position of the pedal 44 is fixed by the limit assembly 5 to prevent the foot assembly 4 from slipping.

[0056] When the support leg assembly 4 moves upward, the upward pulling plate 32 will drive the control rope 51 to move upward, and the control rope 51 will drive the pushing bead 54 to move upward during the pulling process. When the pushing bead 54 slides inside the wire hole 8, the pushing bead 54 will squeeze the pushing ring, thereby pushing the pushing tube 52 out of the wire hole 8. After the pushing tube 52 is completely pushed out, the pushing tube 52 is pressed against the side of the draw plate 31, and the clamping plate 53 will contact the pedal 44, and the pedal 44 will be fixed in position by the clamping plate 53, thereby preventing the support leg assembly 4 from slipping.

[0057] Since most of the main parts of the control rope 51 are located inside the counterweight structure 6, in order to avoid the multiple control ropes 51 from getting entangled with each other during use, the middle part of the control rope 51 is set as an elastic spiral to ensure that the control rope 51 can be automatically and completely coiled when not in use. While saving space, it ensures that the multiple control ropes 51 do not touch each other, thus avoiding entanglement.

[0058] Reference Figure 7 and Fig. 9 , a locking assembly 7 is provided on the pull plate 32, and the locking assembly 7 is used to lock the position of the rotating shaft 41;

[0059] The locking assembly 7 includes a locking plate 71 and a spring column 72. The spring column 72 is fixedly connected to the bottom surface of the locking plate 71, and the bottom end is fixedly connected to the pull plate 32. One end of the control rope 51 passes through the spring column 72 and is fixedly connected to the bottom surface of the locking plate 71. The rotating shaft 41 is provided with an annular latch tooth, and the bottom surface of the locking plate 71 is provided with a fixing tooth. The locking plate 71 is used to fix the rotating shaft 41.

[0060] Since the rotating shaft 41 only relies on the rotating opening on the pull plate 32 to limit the outward rotation angle, when the surveying instrument 1 is hit, the center of gravity is shifted and the support leg assembly 4 away from the impact side will deflect, which can easily cause the surveying instrument 1 to tip over. By setting the locking assembly 7, the three rotating shafts 41 can be quickly locked at the same time, which facilitates the transfer and adjustment of the surveying instrument 1 during multi-point surveying.

[0061] After the adjustment of multiple support leg assemblies 4 is completed, the control rope 51 is driven downward through the counterweight structure 6 below, and the downward moving control rope 51 drives the locking plate 71 to move downward, so that the fixed teeth on the locking plate 71 are engaged with the latching teeth on the rotating shaft 41, thereby fixing the position of the rotating shaft 41. When impacted, the counterweight structure 6 will also pull the control rope 51 due to the effect of inertia, thereby strengthening the locking effect of the locking plate 71 on the rotating shaft 41.

[0062] When the counterweight structure 6 is retracted, the locking plate 71 is separated from the rotating shaft 41 under the elastic support of the spring column 72 , which facilitates the rotation and retraction of the support leg assembly 4 .

[0063] Reference Figure 6 The counterweight structure 6 includes a bottom tube 61 and a counterweight block 62. The bottom tube 61 is vertically fixedly connected to the middle of the bottom surface of the bottom plate 2. The counterweight block 62 is threadedly connected to the bottom end of the bottom tube 61. The bottom ends of the plurality of control ropes 51 are fixedly connected to the counterweight block 62.

[0064] The end of the counterweight block 62 is annularly fixedly connected with a plurality of support blocks 9 , and the support blocks 9 are made of wear-resistant material.

[0065] When the surveying and mapping equipment is in use, most of its weight comes from the surveying instrument 1 above, causing the center of gravity to be located above. When it is hit, it is easy to tilt. The counterweight structure 6 is provided to lower the center of gravity of the entire surveying and mapping equipment, thereby enhancing the stability of the equipment.

[0066] When surveying is required, the counterweight 62 is separated from the bottom tube 61, the counterweight 62 is lowered, and the control rope 51 limits the position of the counterweight 62, thereby moving the overall center of gravity of the equipment downward and improving the stability of the equipment. At the same time, the suspended counterweight 62 can automatically adjust the center of gravity position of the equipment set up on different terrains.

[0067] When not in use, the counterweight block 62 is threadedly connected to the bottom tube 61, which facilitates the overall transfer of the equipment. At the same time, the support block 9 provided below the counterweight block 62 can be used for stable placement of the equipment.

[0068] The control rope 51 plays different roles in the process of the support leg assembly 4 moving up and down. When the support leg assembly 4 moves up, the control rope 51 controls the pushing bead 54, which needs to play the role of linking the pushing tube 52 and fixing the support leg assembly 4. After the support leg assembly 4 moves down, the control rope 51 is used for the lower counterweight block 62 to lock the rotating shaft 41 at the same time.

[0069] Reference Figure 7 and Fig.10The bottom surface of the drawer plate 31 is provided with a limiting groove, and the limiting groove is used to limit the position of the pedal 44. The bottom surface of the pedal 44 is provided with a recess, and the clamping plate 53 is provided with a protrusion for clamping the recess. The pedal 44 and the clamping plate 53 are both made of rubber material.

[0070] The limiting groove can hide the pedal 44, thereby increasing the aesthetics of the entire device. At the same time, when the support leg assembly 4 is fixed, the movable card plate 53 will slowly contact the bottom surface of the pedal 44, and the positions of the card plate 53 and the pedal 44 are fixed and limited by the recesses and protrusions. The elastic card plate 53 can be quickly and elastically installed and disassembled, ensuring portability in use.

[0071] Reference Fig.11 A side panel 10 is provided on the side of the drawer 31, a pull-out opening is opened on the side panel 10, a magnetic strip 11 is provided on the inner side of the side panel 10, and a plurality of magnetic blocks 12 are provided on the side of the bottom plate 2, and the plurality of magnetic strips 11 are magnetically connected to the plurality of magnetic blocks 12.

[0072] The side panel 10 can quickly pull the drawer plate 31. When the side panel 10 is completely pushed into the slide groove, the position of the side panel 10 is fixed by the mutual magnetic attraction between the magnetic block 12 and the magnetic strip 11, thereby ensuring the restriction of the position of the displacement assembly 3, preventing the displacement assembly 3 from sliding outward during use, and ensuring the normal use of the support leg assembly 4.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
