[0022] Please see Figures 1 to 8 The following describes the level instrument for architectural engineering surveying provided by the present invention. A level instrument for architectural engineering surveying includes an installation mechanism, a level instrument body 6, a vertical adjustment mechanism 4, and a horizontal adjustment mechanism 5. The installation mechanism is located on the ground and has a support member 3. The support member 3 has a control cavity 31, and its upper end has an opening 32 communicating with the control cavity 31. The level instrument body is installed on the support member 3. The vertical adjustment mechanism 4 is located on the installation mechanism. The vertical adjustment mechanism 4 includes two adjustment plates 41 and two limiting members 42. The two adjustment plates 41 are located on both sides of the support member 3, and each adjustment plate 41 has an elongated hole 411 along its length, and the elongated hole 411 has an arc-shaped structure. The two limiting members 42 are respectively located within the elongated hole 411 and have an arc-shaped structure along the elongated hole 411. The inner wall has a degree of freedom for sliding; one end of each of the two limiting members 42 is fixedly connected to the support member 3; the limiting member 42 is also provided with a locking member 43 to restrict the movement of the limiting member 42; the support member 3 changes its angle in the vertical direction as the limiting member 42 moves in the long hole 411 of the arc structure; the horizontal adjustment mechanism 5 is provided on the support member 3; the horizontal adjustment mechanism 5 includes a transmission assembly 51 and two adjustment assemblies 52; the transmission assembly 51 is provided in the control cavity 31, the level body 6 is provided on the transmission assembly 51 and is located outside the control cavity 31; the two adjustment assemblies 52 are respectively provided on the two limiting members 42 and are connected to the transmission assembly 51 through the corresponding limiting members 42, and are used to control the angle of the level body 6 in the horizontal direction.

[0023] Compared with the prior art, the level instrument for building engineering surveying provided in this embodiment, when used, involves setting up the installation mechanism on the ground and leveling the instrument body 6 using the vertical adjustment mechanism 4 and the horizontal adjustment mechanism 5. Since the instrument body 6 is mounted on the transmission assembly 51, and the transmission assembly 51 is located within the control cavity 31, and the adjustment plate 41 has an arc-shaped elongated hole 411 along its length, the limiting member 42 moves within the arc-shaped elongated hole 411 and rotates along its inner wall, thereby driving the support member 3 to move and rotate on the installation mechanism, thus adjusting the angle of the instrument body 6 in the vertical direction. Because the adjustment component 52 of the horizontal adjustment mechanism 5 passes through the limiting member 42 and the support member 3 and is connected to the transmission... The transmission component 51 is connected to the transmission component 51, so the angle of the level instrument body 6 in the horizontal direction can be adjusted by controlling the transmission component 51 through the adjustment component 52. After the angle adjustment is completed, the locking component 43 is used to lock the limiting component 42 to prevent the locking component 43 from moving, thereby fixing the level instrument body 6. In this way, the limiting component 42 of the vertical adjustment mechanism 4 moves within the elongated hole 411 of the arc structure to adjust the angle of the level instrument body 6 in the vertical direction. At the same time, the adjustment component 52 and the transmission component 51 of the horizontal adjustment mechanism 5 are used to adjust the angle of the level instrument body 6 in the horizontal direction, which meets the needs of the staff. It can be adjusted in both vertical and horizontal directions, which improves the adjustment efficiency. At the same time, fixing the level instrument body 6 after adjustment also facilitates the measurement of the level instrument body 6.

[0024] Please see Figures 1 to 5As a specific embodiment of the level instrument for architectural engineering surveying provided by the present invention, the adjustment component 52 includes an adjustment rod 521, an adjustment sleeve 522, a gear 523, and a transmission rod 524; one end of the adjustment rod 521 is connected to the limiting member 42; the adjustment rod 521 has a transmission groove 525, and the opening 32 of the transmission groove 525 is set in a direction away from the limiting member 42; one end of the adjustment sleeve 522 is sleeved on the adjustment rod 521 and rotatably connected to the adjustment rod 521, and an internal gear ring 526 is provided inside the adjustment sleeve 522; the transmission rod 524 is located in the transmission groove 525, and one end passes through the limiting member 42 and the support member 3, and is connected to the transmission component 51; the gear 523 is located on the transmission rod 524 and outside the transmission groove 525, and the gear 523 meshes with the internal gear ring 526; when leveling is required... When adjusting the horizontal angle of the instrument body 6, the adjusting sleeve 522 is rotated on the adjusting rod 521. The adjusting sleeve 522 drives the internal gear ring 526 to rotate, which in turn drives the gear 523 to rotate. The gear 523 then drives the transmission rod 524 to rotate. Since the transmission rod 524 is connected to the transmission assembly 51, it drives the transmission assembly 51 to rotate horizontally, thereby adjusting the angle of the instrument body 6. Because the adjusting rod 521 is connected to the limiting member 42, when adjusting the angle, the operator can adjust the horizontal angle of the instrument body 6 by holding and rotating the adjusting sleeve 522 with both hands. By controlling the movement of the adjusting sleeve 522 with both hands, which in turn moves the adjusting rod 521 and the limiting member 42, the vertical angle of the instrument body 6 can be adjusted, which is very convenient.

[0025] Please see Figure 2 , Figure 6 and Figure 8 As a specific embodiment of the level instrument for architectural engineering surveying provided by the present invention, the transmission assembly 51 includes two first bevel gears 511, a second bevel gear 512, and a connecting rod 513. The two first bevel gears 511 are both located within the control cavity 31 and connected to their corresponding transmission rods 524. The second bevel gear 512 is located above the two first bevel gears 511 and meshes with them respectively. The level instrument body 6 is mounted on the second bevel gear 512. One end of the connecting rod 513 is rotatably connected to the second bevel gear 512, and the other end is rotatably connected to the bottom surface of the support member 3. When the transmission rod 524 rotates, it drives the first bevel gear 511 to rotate, which in turn drives the second bevel gear 512 to rotate, thereby causing the second bevel gear 512 to drive the level instrument body 6 to rotate, thus adjusting the angle of the level instrument body 6 in the horizontal direction. The two ends of the connecting rod 513 are rotatably connected to the second bevel gear 512 and the bottom surface of the support member 3 respectively, so that the rotation of the second bevel gear 512 is more stable.

[0026] Please see Figure 1 , Figure 2 and Figure 6As a specific embodiment of the level instrument for building engineering surveying provided by the present invention, the adjusting sleeve 522 is slidably connected to the adjusting rod 521; in order to prevent the internal gear ring 526 inside the adjusting sleeve 522 from rotating due to accidental contact with the adjusting sleeve 522 and changing the angle of the level instrument body 6, after the level instrument body 6 is leveled, the adjusting sleeve 522 is controlled to slide on the adjusting rod 521 so that the internal gear ring 526 and the gear 523 are separated, thereby preventing the adjusting sleeve 522 from changing the angle of the level instrument body 6 due to accidental contact.

[0027] Please see Figure 3 , Figure 4 and Figure 7 As a specific embodiment of the level instrument for architectural engineering surveying provided by the present invention, the limiting member 42 includes a limiting block 421 and a limiting post 422; the limiting block 421 is slidably connected to the elongated hole 411, and one end is connected to the support member 3; the limiting post 422 is located at the end of the limiting block 421 away from the support member 3, and is connected to the adjusting rod 521; the limiting post 422 is provided with an external thread, and the locking member 43 is sleeved on the limiting post 422, and the locking member 43 is provided with an internal thread that is threadedly connected to the external thread. Since the limiting block 421 is slidably connected to the elongated hole 411 and one end is connected to the support member 3, the limiting block 421 moves and rotates within the arc-shaped elongated hole 411, thereby driving the support member 3 to move and rotate, thus adjusting the angle of the level body 6 in the vertical direction. Since the internal thread of the locking member 43 is threadedly connected to the external thread of the limiting post 422, after the level body 6 is leveled, the limiting block 421 is locked by rotating the locking member 43 to prevent the limiting block 421 from moving arbitrarily.

[0028] Please see Figure 4 and Figure 5 As a specific embodiment of the level instrument for building engineering surveying provided by the present invention, the upper and lower inner walls of the elongated hole 411 are provided with a sliding groove 412 with the same curvature as the elongated hole 411; the upper and lower ends of the limiting block 421 are provided with limiting rods 424 that are slidably connected to the sliding grooves 412; with the help of the limiting rods 424 and the sliding grooves 412, not only can the movement of the limiting block 421 be made more stable, but the limiting block 421 can also be prevented from shaking randomly.

[0029] Please see Figure 4 and Figure 5As a specific embodiment of the level instrument for architectural engineering surveying provided by the present invention, the limiting block 421 is provided with a limiting groove 423 corresponding to the two limiting rods 424, and the limiting rods 424 are slidably connected to the limiting grooves 423; an elastic element 425 is provided in the limiting groove 423, and the two ends of the elastic element 425 are respectively connected to the limiting rods 424 and the bottom of the limiting groove 423; when the movement of the limiting rods 424 is obstructed, the limiting rods 424 can squeeze the elastic element 425 to continue moving, and then the elastic element 425 pushes the limiting rods 424 to reset with the help of elastic force. Therefore, the movement of the limiting rods 424 in the sliding groove 412 can be made smoother with the help of the elastic element 425; the elastic element 425 is a spring.

[0030] Please see Figure 2 As a specific embodiment of the level instrument for building engineering surveying provided by the present invention, the limiting column 422 and the limiting block 421 are integrally formed; by setting the limiting column 422 and the limiting block 421 as integrally formed, the overall structure of the limiting column 422 and the limiting block 421 is continuous and complete, which can effectively avoid the structural weakness caused by stress concentration at the splice, and has higher strength and stability.

[0033] Please see Figure 1As a specific embodiment of the level instrument for architectural engineering surveying provided by the present invention, the reset assembly 13 includes a limiting sleeve 131, a support rod 132, and multiple reset components 133; the limiting sleeve 131 is sleeved on multiple support legs 12 and slidably connected to the multiple support legs 12; one end of the support rod 132 is disposed on the mounting plate 11 and is located between the multiple support legs 12; a connecting sleeve 134 is provided on the support rod 132; one end of each of the multiple reset components 133 is connected to a multiple corresponding support legs 12, and the other end of each is connected to the connecting sleeve 134; the limiting sleeve 131... When the support leg 12 slides downwards along its length, the limiting sleeve 131 presses the support leg 12 to rotate toward the support rod 132, thereby retracting the support leg 12. At the same time, the reset member 133 is compressed. When the limiting sleeve 131 slides upwards, the reset member 133 resets with the help of elasticity, thereby allowing the support leg 12 to support the mounting plate 11.
