Description

Technical Field

[0001] The utility model relates to the technical field related to building construction, in particular to an auxiliary positioning type on-site measuring instrument for building construction. Background Art

[0002] Housing construction projects are generally referred to as construction projects or housing construction projects. They refer to the various technical works such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures, as well as the completed engineering entities. Surveying instruments are needed during the construction of houses.

[0003] A measuring device for building construction disclosed in the publication number CN213515654U is characterized in that a fixed seat is fixed on the measuring site, and then the base of the measuring instrument body is fixed on the top of four square connecting pieces. When the triangular bracket at the bottom of the measuring instrument body sinks into the soil as the measuring time progresses, causing the measuring instrument body to tilt, the two first supporting pieces on the fixed seat are rotated to the lowest side of the bottom of the triangular bracket, and the L-shaped handle is rotated. The L-shaped handle drives the first rotating shaft column fixedly connected to rotate on the two first supporting pieces, and the second bevel gear fixedly connected on the first rotating shaft column drives the meshing first bevel gear to rotate. The first bevel gear drives the fixedly connected threaded rod to rotate in the middle of the top of the first square connecting block. After the threaded rod rotates, the opening of the second square connecting block rotates and drives the second square connecting block to rise. The second square connecting block drives one side of the support to rise, and the support then drives the lowest side of the measuring instrument body to rise. While continuously rotating the L-shaped handle, observe the leveling device of the measuring instrument body. When the measuring instrument body is horizontal, stop rotating the L-shaped handle, and then operate the measuring instrument body to measure.

[0004] However, the above scheme still has the following problems during use: when in use, the measuring instrument is simply mounted on the bracket, and the positioning stability of the measuring instrument is poor, so that the connection between the measuring instrument and the bracket is not strong enough during use, which can easily cause the measuring instrument to fall and be damaged. When the ground is uneven, it is not convenient to quickly perform automatic leveling.

[0005] Therefore, we propose an auxiliary positioning type on-site measuring instrument for building construction in order to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0030] 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. Example

[0031] In order to solve the problem that the existing on-site measuring instrument for building construction is not convenient for auxiliary positioning of the measuring instrument body 3 during use, which affects the stability during use, the following solution is proposed. For details, please refer to Figure 1-Figure 3 As shown, the auxiliary positioning type on-site measuring instrument for building construction includes a base plate 1 placed on the ground, a base 2 is arranged on the top of the base plate 1, a measuring instrument body 3 is installed on the top of the base 2, and transverse grooves 13 are symmetrically opened on the top of the base 2. The transverse grooves 13 are located around the outside of the measuring instrument body 3. A positioning plate 14 is slidably connected in the transverse groove 13. The positioning plate 14 is clamped and abutted against the outer side of the measuring instrument body 3. The positioning plate 14 is used for auxiliary positioning of the measuring instrument body 3.

[0032] Please refer to Figure 1-Figure 3 As shown, specifically, a toothed plate 9 is slidably connected through the middle of the top surface of the base 2, and the toothed plate 9 is located below the measuring instrument body 3. The toothed plate 9 is arranged in a "T"-shaped structure, and a spring 10 is installed between the bottom of the toothed plate 9 and the base 2. A gear 11 is meshed with the vertical portion of the toothed plate 9, and the bearing of the gear 11 is connected to the inner middle portion of the base 2. A first screw 12 is integrally installed on the left and right sides of the middle of the gear 11, and the bearing of the first screw 12 is connected to the transverse groove 13. A positioning plate 14 is threadedly connected to the end of each first screw 12 away from the gear 11, and the positioning plate 14 is arranged in a "C"-shaped structure when viewed from above.

[0033] When the measuring instrument body 3 is placed on the top of the base 2, a force is applied to the tooth plate 9, and the tooth plate 9 moves downward. After the tooth plate 9 moves downward, the spring 10 is compressed. When the tooth plate 9 moves downward, it drives the gear 11 to rotate. After the gear 11 rotates, it drives the first screw 12 to rotate synchronously. After the first screw 12 rotates, it drives the positioning plate 14 to move in the transverse groove 13, thereby positioning and reinforcing the measuring instrument body 3.

[0034] In order to make the on-site measuring instrument for building construction automatically level when in use and avoid the problem of data difference, the following solution is proposed. Please refer to Figure 1 and Figure 4 As shown:

[0035] A sleeve 4 is installed at the four corners of the top of the base plate 1, and a slide rod 5 is slidably connected in the sleeve 4. The slide rod 5 is fixed at the four corners of the bottom of the base 2 accordingly. The sleeve 4 and the slide rod 5 are sealed and slidably connected. Oil 6 is poured inside the sleeve 4 and the bottom of the slide rod 5. Adjacent sleeves 4 are connected to each other through connecting pipes 7. The sleeve 4, the slide rod 5 and the oil 6 constitute an automatic leveling structure.

[0036] A valve 8 is installed in the middle of each connecting pipe 7. When the device needs to be leveled, the valve 8 on the connecting pipe 7 is opened, the interior of the surrounding sleeves 4 will be in a connected state, and the oil 6 will flow due to gravity, thereby driving the slide rod 5 to slide in the sleeve 4, thereby automatically finding a balanced position, and then avoiding the valve 8 to fix the leveled state.

[0037] In order to improve the overall stability of the on-site measuring instrument for building construction, the following solution is proposed. Please refer to Figure 1 and Figure 5-Figure 7 As shown:

[0038] The device further comprises a second screw 18 and a support leg 16, wherein the support leg 16 is sleeved on the bottom end of the second screw 18, the support leg 16 is threadedly connected to the bottom end of the second screw 18, and the support leg 16 is located below the support tube 15. The second screw 18 is rotatably disposed in the support tube 15, and the second screw 18 rotates to drive the support leg 16 to rise or fall relative to the support tube 15.

[0039] Furthermore, the measuring instrument further comprises a knob 17 and a bevel gear connector, the bevel gear connector is located in the support tube 15 and above the second screw 18, the bevel gear connector comprises a first bevel gear and a second bevel gear, the first bevel gear is fixedly arranged at the top end of the second screw 18, and the second bevel gear is meshed with the first bevel gear. The knob 17 is rotatably arranged on the support tube 15, one end of the knob 17 is located outside the support tube 15, and the other end of the knob 17 is fixedly connected to the second bevel gear;

[0040] When the relative positions of the support legs and the support rod need to be adjusted, the support tube 15 at the bottom of the base plate 1 is rotated and opened to support the ground, and then the knob 17 on the support tube 15 is rotated. The knob 17 will drive the second screw rod 18 to rotate through the bevel gear connector. After the second screw rod 18 rotates, it will drive the support legs 16 to slide out of the support tube 15 to adjust the use length. This arrangement makes the operation more convenient and quick.

[0041] Auxiliary rods 19 are hinged on the opposite surfaces of the three support cylinders 15, and the ends of the auxiliary rods 19 are slidably connected to the sliding sleeves 20. The sliding sleeves 20 are located in the middle between the three support cylinders 15, and the sliding sleeves 20 are set as a disc-shaped structure.
