[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Figure 1 An embodiment of a level instrument support device of the utility model is shown, see Figure 1 In this embodiment, a level support device includes a level and a support device arranged under the level, and the support device includes: a bracket 1, a mounting seat 2, a mounting plate 3 and a locking assembly 4.

[0028] Among them, see Figure 1 The mounting seat 2 is arranged at the top of the bracket 1, and the top surface of the mounting seat 2 is provided with a mounting groove 201. The mounting plate 3 is movably installed in the mounting groove 201, and the top surface of the mounting plate 3 exposes the mounting groove 201 and is fixedly connected to the bottom of the level. The locking assembly 4 includes two limit plates 401 arranged oppositely and suspended on the mounting plate 3 on opposite sides. The bottom surface of each limit plate 401 is in the same plane as the top surface of the mounting plate 3, driving the two limit plates 401 to move closer to or away from each other, so that the two limit plates 401 are both on the mounting plate 3, or are both outside the top surface of the mounting plate 3. When the two limit plates 401 are both on the top surface of the mounting plate 3, the mounting plate 3 can be locked in the mounting groove 201 to achieve the connection between the level and the supporting device; when the two limit plates 401 are both outside the top surface of the mounting plate 3, the restriction of the mounting plate 3 is released, and the level and the supporting device can be easily separated; compared with the bolt fastening method, the scheme of this embodiment makes it convenient to connect or disassemble the level and the supporting device.

[0029] Further, see Figure 2 and Figure 3 The mounting seat 2 is provided with a hollow cavity 202, and an opening 203 communicating with the cavity 202 is provided on the top surface of the mounting seat 2 facing each limiting plate 401, a slide groove 204 is provided on the inner bottom surface of the cavity 202 corresponding to each opening 203, and a circular hole 205 communicating with the cavity 202 is provided on the side wall of the mounting seat 2.

[0030] Further, see Figure 2The locking assembly 4 also includes a slider 402, a fan-shaped plate 403, a connecting rod 404 and a roller 405 arranged in the mounting seat 2; the bottom ends of the two limit plates 401 are respectively connected to the top ends of the two sliders 402, and the bottom ends of the two sliders 402 extend into the two slide grooves 204 through the two openings 203 respectively. The two sides of the two sliders 402 that are away from each other are each connected to a fan-shaped plate 403, and the outer arc surfaces of the two fan-shaped plates 403 are away from each other. The connecting rod 404 is arranged on the side of the moving direction of the slider 402, and the axis of the connecting rod 404 is parallel to the moving direction of the slider 402, and the two axial ends are respectively rotatably connected to the rotating shafts of the two rollers 405 through the connecting plates, and the two rollers 405 are respectively in contact with one side of the outer arc surface of the two fan plates 403 adjacent to the connecting rod 404. Driving the connecting rod 404 towards or away from the slider 402 can drive the two rollers 405 to move. Since the moving route of the roller 405 is fixed, when the moving roller 405 contacts the outer arc surface of the fan plate 403, it will press the two fan plates 403 closer to each other, thereby making the slider 402 connected to the two fan plates 403 closer to each other, and then drive the two limit plates 401 to move to the top surface of the mounting disk 3.

[0031] Optionally, both openings 203 are linear structures and are respectively arranged along the moving direction of the two sliders 402. The ends of the two openings 203 that are close to each other extend into the mounting groove 201 respectively, so that when the two sliders 402 are close to each other, each limit plate 401 can be within the top surface area of ​​the mounting plate.

[0032] Optionally, the width of the opening 203 and the width of the slide groove 204 are both consistent with the width of the slider 402 to prevent the two sliders 402 from changing their positions when they move closer to or farther away from each other.

[0033] Optionally, protrusions are provided at both axial ends of the connecting rod 404 , and respectively contact the inner walls of the inner top and bottom of the cavity 202 to limit the connecting rod 404 .

[0034] Further, see Figure 2 The lock assembly 4 also includes a sleeve 406, a screw rod 407 and a rotating disk 408. The sleeve 406 is arranged in the middle of the connecting rod 404. An internal thread that matches the external thread of the screw rod 407 is arranged inside the sleeve 406. One end of the screw rod 407 extends into the cavity 202 through the circular hole 205. The end of the screw rod 407 that extends into the cavity 202 is threaded through the sleeve 406 and is rotatably connected to the inner wall of the cavity 202 through a bearing. The other end of the screw rod 407 is outside the mounting seat 2 and is coaxially connected to the rotating disk 408, driving the rotating disk 408 to rotate around its own axis to drive the screw rod 407 to rotate. Since the sleeve 406 is arranged on the connecting rod 404, when the screw rod 407 rotates, the sleeve 406 can only move along the axial direction of the screw rod 407, thereby driving the connecting rod 404 to approach or move away from the slider 402.

[0035] Optionally, the internal thread of the sleeve 406 is coaxial with the circular hole 205 and parallel to the moving direction of the connecting rod 404, so that the screw rod 407 can only rotate around its own axis.

[0036] Further, see Figure 2 The lock assembly 4 also includes: a baffle 409, a round rod 410 and a spring 411. A baffle 409 is provided on each side of the two sliders 402 that are close to each other. The two baffles 409 are connected to one end of a round rod 410 on each side that are away from each other. The other ends of the two round rods 410 are away from each other and penetrate the two sliders 402 respectively. The part of each round rod 410 between the baffle 409 and the slider 402 associated with it is sleeved with a spring 411. When the two sliders 402 are close to each other, the two springs 411 are squeezed respectively, and the springs 411 accumulate elastic potential energy; when the two sliders 402 lose their restrictions, the two springs 411 release their elastic potential energy respectively to drive the two sliders 402 away from each other, thereby driving the two limit plates 401 to move to the area outside the top surface of the mounting plate. In this way, the connection restriction between the level and the supporting device can be released, and the level can be easily removed from the supporting device.

[0037] Further, see Figure 3 The mounting plate 3 is provided with a notch 301 corresponding to each slider 402 and matched with its side wall. When the two limiting blocks 206 are both in the two notches 301 , the two limiting plates 401 are both located in the area within the top surface of the mounting plate 3 .

[0038] Further, see Figure 3 At least one limit block 206 is provided on the inner wall of the mounting groove 201, and a limit groove 302 adapted to each limit block 206 is provided on the side wall of the mounting plate 3. Each limit groove 302 clamps each limit block 206 respectively, so that when the mounting plate 3 is placed in the mounting groove 201, the two notches 301 can face the two sliders 402 respectively.

[0039] In this embodiment, the mounting disk 3 connected to the level is placed in the mounting groove 201, and the external force drives the rotating disk 408 to rotate clockwise or counterclockwise around its own axis to drive the connecting rod 404 to approach the slider 402, thereby driving the two rollers 405 to squeeze the two fan-shaped plates 403, and then making the two sliders 402 approach each other. When the two sliders 402 are both in the notch 301 of the mounting disk 3, the two limit plates 401 are respectively located in the top surface area of ​​the mounting disk 3, so as to lock the mounting disk 3 in the mounting groove 201, thereby realizing the connection between the level and the supporting equipment. The external force drives the rotating disk 408 to rotate counterclockwise or clockwise around its own axis to drive the connecting rod 404 away from the slider 402, thereby driving the two rollers 405 to move to the side of the outer arc surface of the two sector plates 403 adjacent to the connecting rod 404. When the two sliders 402 lose the pressure from the two sector plates 403, the two springs 411 release elastic potential energy and push the two sliders 402 away from each other, so as to drive the two limit plates 401 to move outside the top surface area of ​​the mounting plate. The mounting disk 3 loses the restriction of the limit plates 401, and the level can be directly removed from the mounting seat 2. Compared with the method of fastening the level and the supporting device with bolts, the solution provided in this embodiment makes it more convenient to connect or disassemble the level and the supporting device.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
