[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0026] See also Figures 1 to 3 As shown, a level includes a level body 1, a tripod 2, an annular sleeve 3 and a support assembly 4. The level body 1 is a prior art and is used to measure the height difference between ground points, which will not be described in detail here. In this embodiment, the tripod 2 includes a connecting block 21, three legs 22 and a lifting rod 23, wherein the lifting rod 23 is vertically penetrated on the connecting block 21 and is slidably connected to the connecting block 21, and the top of the lifting rod 23 is fixedly connected to the level body 1, which is used to drive the level body 1 to rise and fall, and the three legs 22 are arranged at the lower part of the connecting block 21 along the circumferential array of the connecting block 21, and are hinged to the connecting block 21, wherein the legs 22 are retractable legs 22 in the prior art, which are used to adjust the height and level of the level body 1, which will not be described in detail here.

[0027] There are two annular sleeves 3, which are respectively clamped on two adjacent legs 22 of the tripod 2. In this embodiment, the annular sleeve 3 is an annular plate with an opening on one side, which is sleeved on the corresponding leg 22. Connecting plates 31 are respectively protruding on both sides of the opening of the annular sleeve 3, and the two connecting plates 31 are fixedly connected by first bolts 32 and butterfly nuts (not shown in the figure). During implementation, the connecting plates 31 on both sides of the opening are moved in a direction close to or away from each other by rotating the butterfly nuts forward or backward. When the butterfly nuts are adjusted to move the two connecting plates 31 in a direction away from each other, the staff can adjust the position of the annular sleeve 3. When the annular sleeve 3 needs to be clamped with the leg 22, the butterfly nuts are tightened to move the two connecting plates 31 in a direction close to each other until the inner wall of the annular sleeve 3 abuts against the outer wall of the leg 22. A hanging buckle 33 is fixed on the side of the annular sleeve 3 away from the connecting plate 31, which is used to clamp the support assembly 4.

[0028] The support assembly 4 is used to receive the recording board to facilitate the staff to record during the surveying and mapping process. During the measurement process, the support assembly 4 is arranged on the outside of the tripod 2, and a plurality of openings 421 are provided on one side of the support assembly 4. The plurality of openings 421 are arranged at intervals along the length direction of the support assembly 4. The hanging buckles 33 on each annular sleeve 3 are respectively clamped in the corresponding openings 421 to clamp the support assembly 4. In this embodiment, the hanging buckle 33 includes a connecting rod 331 and a connecting head 332. One end of the connecting rod 331 is fixedly connected to the annular sleeve 3, and the other end of the connecting rod 331 is fixedly connected to the connecting head 332. The outer diameter of the connecting head 332 is greater than the outer diameter of the connecting rod 331. The opening 421 includes a first through hole 4211 and a positioning hole 4212 arranged above the first through hole 4211. The inner diameter of the first through hole 4211 is greater than or equal to the outer diameter of the connecting head 332, and the inner diameter of the positioning hole 4212 is equal to the outer diameter of the connecting rod 331.

[0029] During implementation, the staff takes the support assembly 4, first passes the connector 332 through the first through hole 4211, and then presses the support assembly 4 downward to engage the connecting rod 331 in the positioning hole 4212. Otherwise, the support assembly 4 can be taken out. By providing the connector 332, the connecting rod 331, the first through hole 4211 and the positioning hole 4212, the support assembly 4 is firmly engaged with the annular sleeve 3, and the staff can disassemble it quickly.

[0030] Specifically, the support assembly 4 includes a base plate 41 and a hanging plate 42 hinged on one side of the base plate 41 in the width direction. A plurality of openings 421 are provided on the hanging plate 42. A stopper 422 is fixedly provided on the bottom of the hanging plate 42, on the side close to the tripod 2. When the hanging plate 42 rotates in a direction away from the base plate 41 and rotates until the width direction of the hanging plate 42 is perpendicular to the width direction of the base plate 41, the stopper 422 abuts against the base plate 41. That is, the maximum angle of rotation of the hanging plate 42 in the direction away from the base plate 41 is a right angle. During implementation, the staff rotates the hanging plate 42 in a direction away from the base plate 41 until the stopper 422 abuts against the top surface of the base plate 41. At this time, the angle between the hanging plate 42 and the base plate 41 is vertical, so that after the hanging plate 42 is clamped with the annular sleeve 3, the base plate 41 can receive the recording board. When the hanging plate 42 rotates in a direction close to the base plate 41, the support assembly 4 can be a rectangular parallelepiped structure to facilitate the storage of the support assembly 4.

[0031] It should be noted that when the tripod 2 is in the supporting state, the upper parts of the three legs 22 are in a state of being inclined toward the central axis of the tripod 2. Therefore, after the support assembly 4 is engaged with the hanging buckle 33, it is also in a state of being inclined toward the central axis of the tripod 2. At this time, the staff places the bottom of the recording board on the top surface of the bottom plate 41, and the two sides of the upper part of the recording board will be inclined and overlapped on the two adjacent legs 22.

[0032] Preferably, a baffle plate 5 for supporting the recording board is rotatably connected to the side of the support assembly 4 close to the opening 421. In this embodiment, the baffle plate 5 is located on the side of the hanging plate 42 away from the tripod 2. One end of the baffle plate 5 is arranged in the middle of the length direction of the hanging plate 42, and is rotatably connected to the hanging plate 42 through the third bolt 51 and the third nut 52. During implementation, the staff rotates the third nut 52 to move away from the third bolt 51, and the baffle plate 5 can rotate along the central axis of the third bolt 51. When the baffle plate 5 rotates to a preset position, the staff rotates the third nut 52 to the direction close to the third bolt 51, so that the baffle plate 5 cannot rotate, and the back side of the recording board can be supported.

[0033] Furthermore, a side of the hanging plate 42 away from the tripod 2 is provided with a recess 423 for accommodating the baffle 5. Figure 1As shown, the clearance groove 423 is provided with a clearance opening 4231 just above the third bolt 51. During implementation, when the length direction of the baffle 5 is perpendicular to the length direction of the hanging plate 42 (the baffle 5 is in a state of supporting the recording board), the baffle 5 is clamped in the clearance opening 4231 of the clearance groove 423; when the support assembly 4 needs to be stored, the third nut 52 is rotated to move the third nut 52 away from the third bolt 51, and the baffle 5 is rotated and accommodated in the clearance groove 423 (at this time, since the third nut 52 moves away from the third bolt 51, the gap between the end of the third bolt 51 away from the third nut 52 and the third nut 52 increases, and the baffle 5 can move along the axial direction of the third bolt in this gap, and the baffle 5 can first be separated from the limit of the clearance groove 423, and then rotated to the inside of the clearance groove 423) to facilitate storage. That is, when the hanging plate 42 rotates toward the bottom plate 41 and rotates until one side of the hanging plate 42 abuts against the top surface of the bottom plate 41 , the recording board is sandwiched between the bottom plate 41 and the hanging plate 42 .

[0034] Preferably, the top surface of the bottom plate 41 is slidably connected with a clamping plate 6 on the side away from the tripod 2, and straight slots 411 are respectively opened on both sides of the length direction of the bottom plate 41, and the length direction of the straight slots 411 is parallel to the width direction of the bottom plate 41. A second bolt 61 is respectively arranged on the outside of each straight slot 411, and the top of the second bolt 61 passes through the straight slot 411 and is screwed to the clamping plate 6, and the outer diameter of the bottom end of the second bolt 61 is greater than the width of the straight slot 411. During implementation, by adjusting the second bolt 61, the clamping plate 6 can be moved along the axial direction of the straight slot 411, and then the recording plate can be clamped by the clamping plate 6, so that the recording plate is fixed more firmly.

[0035] In another embodiment of the utility model, a storage space (not shown in the figure) for accommodating the support assembly 4 is provided inside the lifting rod 23, and a bottom cover 7 is screwed to the bottom end of the lifting rod 23. That is, the bottom cover 7 is used to open or close the storage space. The width of the support assembly 4 is smaller than the diameter of the storage space. When the support assembly 4 is not in use, the staff can open the bottom cover 7 and store the support assembly 4 in the storage space.

[0036] When the utility model is implemented, the staff fixes the level body 1 on the top of the tripod 2, adjusts the height and level of the tripod 2, then opens the bottom cover 7, takes out the support assembly 4, rotates the hanging plate 42 away from the bottom plate 41, and clamps the hanging plate 42 with the hanging buckle 33, thereby realizing the clamping of the support assembly 4 and the tripod 2. At this time, the stopper 422 abuts against the top surface of the bottom plate 41, and then rotates the third nut 52, and at the same time rotates the baffle 5 to the clearance opening 4231 of the clearance groove 423, and then tightens the third nut 52, at this time, the baffle 5 is clamped at the clearance opening 4231 of the clearance groove 423. After placing the recording board on the top surface of the bottom plate 41, the staff rotates the second bolt 61 to adjust the position of the clamping plate 6, thereby making the clamping plate 6 clamp the bottom of the recording board on the support assembly 4 to prevent the recording board from falling.

[0037] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
