Background Art

Construction engineering cost technology is a professional field involving cost management and budgeting of engineering projects, aiming to ensure that projects are completed within budget and achieve economic benefits. Construction engineering cost field surveying instruments are instruments and equipment used for measurement, drawing and cost evaluation in construction engineering projects. These devices are designed to help engineering professionals conduct on-site measurements, draw drawings, estimate costs and perform quality control.

Common on-site surveying instruments, such as the one with publication number CN111578083A, discloses a convenient and adjustable surveying device for construction project cost on-site. The inclination angle of multiple adjustable supporting legs can be adjusted at the same time through an angle adjustment component, that is, the opening angle of the adjustable supporting legs can be adjusted so that the adjustable supporting legs can provide stable support for the device. Adjusting the opening angle of the adjustable supporting legs can also, to a certain extent, adjust the height of the surveying instrument body, thereby improving the convenience of on-site cost surveying.

However, considering that the angle adjustment component requires multiple rotations of the crank handle clockwise or counterclockwise to rotate the bevel gear, thereby driving the threaded rod to rotate, and then adjusting the inclination angle of the support leg, it is inconvenient to adjust the inclination angle of the support leg, thereby reducing the working efficiency of the surveying instrument.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

Please refer to Figures 1 to 3. The utility model provides a conveniently adjustable on-site surveying instrument for construction engineering cost, including a support plate 1. The top outer wall of the support plate 1 is rotatably connected to a cylinder 2. The cylinder 2 rotates along the outer wall of the support plate 1 to drive the surveyor 3 to rotate. The top outer wall of the cylinder 2 is fixedly connected to the surveyor 3. The construction engineering cost site is surveyed by the surveyor 3. The bottom outer wall of the support plate 1 is hinged to a support frame 4. The support frame 4 is tilted by rotating around the hinge point. The support plate 1 is supported and fixed by multiple groups of support frames 4. The bottom outer wall of the support plate 1 is fixedly connected to a guide rod 5. The outer wall of the guide rod 5 is slidably connected to a ring 6. The ring 6 slides along the outer wall of the guide rod 5 to drive the connecting rod 7 to move. The outer wall of the ring 6 is hinged to the connecting rod 7. The moving effect of the connecting rod 7 drives the support frame 4 to change the inclination angle. The outer wall of the connecting rod 7 is hinged to the outer wall of the support frame 4.

The inner wall of the ring 6 is elastically connected with a clamping block 10 through a limit spring 9. Through the elastic force of the limit spring 9, the clamping block 10 always maintains a clamping effect with the clamping groove 8 when not affected by external forces, thereby limiting the ring 6. The outer wall of the guide rod 5 is provided with a clamping groove 8, and the outer wall of the support plate 1 is provided with a limit groove 11. The inner wall of the cylinder 2 is elastically connected with a limit block 13 through a compression spring 12. Through the elastic force of the compression spring 12, the limit block 13 always maintains a clamping effect with the limit groove 11 when not affected by external forces, thereby limiting the cylinder 2.

One end of the limit spring 9 is fixedly connected to the inner wall of the ring 6, and the other end of the limit spring 9 is fixedly connected to the outer wall of the block 10. The fixed connection effect of the limit spring 9, the ring 6 and the block 10 keeps the block 10 fixed to prevent the block 10 from falling off and affecting the clamping effect between the block 10 and the slot 8. There are multiple groups of slots 8, and the multiple groups of slots 8 are symmetrically distributed along the center line of the outer wall of the guide rod 5. By providing multiple groups of slots 8, the slots 8 and the block 10 can be clamped at different positions, and the ring 6 can be limited at different positions.

One end of the compression spring 12 is fixedly connected to the inner wall of the cylinder 2, and the other end of the compression spring 12 is fixedly connected to the outer wall of the limit block 13. The fixed connection effect of the compression spring 12, the cylinder 2 and the limit block 13 keeps the limit block 13 fixed, preventing the limit block 13 from falling off and affecting the clamping effect between the limit block 13 and the limit groove 11. There are multiple groups of limit grooves 11, and the multiple groups of limit grooves 11 are distributed in an annular manner along the outer wall of the support plate 1. By providing multiple groups of limit grooves 11, the limit grooves 11 and the limit block 13 are clamped at different positions, thereby achieving limiting effects on the cylinder 2 at different positions.

The outer wall of the clamping block 10 is slidably connected to the inner wall of the ring 6, and the clamping block 10 slides along the inner wall of the ring 6 to engage or release the clamping effect of the clamping block 10 and the clamping groove 8. The outer wall of the clamping block 10 is engaged with the inner wall of the clamping groove 8, and the clamping effect of the clamping block 10 and the clamping groove 8 allows the guide rod 5 to limit the ring 6. The outer wall of the limit block 13 is slidably connected to the inner wall of the cylinder 2, and the limit block 13 slides along the inner wall of the cylinder 2 to engage or release the clamping effect of the limit block 13 and the limit groove 11. The outer wall of the limit block 13 is engaged with the inner wall of the limit groove 11, and the clamping effect of the limit block 13 and the limit groove 11 allows the support plate 1 to limit the cylinder 2.

When the guide rod 5 is in a position to move, the guide rod 5 is moved to a position where the guide rod 5 is in a position to move the guide rod 5 and ...4 is moved to a position where the support plate 1 is supported.

When the surveying angle needs to be adjusted, the staff presses the limit block 13 to release the clamping effect of the limit block 13 with the limit groove 11, and at the same time releases the limiting effect of the support plate 1 with the cylinder 2. The staff rotates the cylinder 2 along the outer wall of the support plate 1 to adjust the angle of the rotating surveyor 3. After the adjustment is completed, the staff loosens the limit block 13 to make the limit block 13 clamped with the limit groove 11 under the elastic force of the compression spring 12, so that the support plate 1 limits the cylinder 2 and keeps the surveyor 3 fixed.

When the surveying is completed, the staff pulls the block 10 outward and slides upward along the outer wall of the guide rod 5, driving the connecting rod 7 to move, thereby driving the multiple groups of support frames 4 to rotate inward, so that the multiple groups of support frames 4 and the support plate 1 remain in a vertical state, loosen the block 10, limit the support frame 4, keep the support frame 4 fixed, and complete the storage process of the surveying instrument.
