Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a surveying instrument that is easy to adjust the surveying height. Background Technology

[0002] A surveying instrument, simply put, is an instrument and device designed and manufactured for surveying operations, used for data acquisition, processing, and output. It is used in various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry tasks during the planning, design, construction, and operation management phases of engineering construction. It mainly consists of a body and a tripod. To facilitate use by staff, the existing tripods have height adjustment functions, allowing staff to adjust them to a suitable height according to surveying needs during actual surveying.

[0003] Currently, adjusting the height of surveying instruments requires surveyors to manually pull the telescopic rod of the tripod. This makes it difficult to change the height of the surveying instrument while the tripod provides stable support, and the manual pulling of the telescopic rod may be inconvenient, thus affecting the ease of use of the surveying instrument. Utility Model Content

[0004] The purpose of this invention is to provide a surveying instrument that facilitates the adjustment of surveying height, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A surveying instrument with adjustable surveying height includes a surveying instrument body and a support frame. The support frame includes multiple sets of support rods and a placement seat. The placement seat is provided with a moving mechanism for driving the surveying instrument body to move stably up and down. The moving mechanism includes a fixed seat and a housing. The fixed seat is movably disposed on the placement seat, and multiple sets of housings are fixedly disposed on the placement seat.

[0007] Preferably, the mounting base is rotatably provided with fixing bolts for fixing the main body of the surveying instrument.

[0008] Preferably, a lead screw is rotatably mounted inside the housing, a lead screw nut is engaged on the lead screw, a support frame is fixedly mounted on the lead screw nut, and the top of the support frame is fixedly connected to the bottom of the fixed base.

[0009] Preferably, a first gear is fixedly installed at the bottom end of the first lead screw, a rotating shaft is rotatably installed inside the housing, a second gear is fixedly installed on the rotating shaft and meshes with the first gear, a motor is fixedly installed outside the housing, and the output end of the motor is fixedly connected to one end of the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, by installing a fixed base and multiple sets of housings, allows the motor to rotate when it starts. This rotation drives the rotating shaft, causing gear two on the shaft to rotate, which in turn drives gear one and lead screw one to rotate. Since lead screw one and lead screw nut are threadedly connected, the rotation of lead screw one causes the lead screw nut to move linearly. Because the support rod is fixedly connected to the lead screw nut, the linear movement of the lead screw nut will drive the support rod and the fixed base connected to it to move linearly. This allows the surveyor to make stable height adjustments to the surveying instrument while the support frame provides stable support, adapting to different surveying needs and helping to improve the efficiency and accuracy of surveying work.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4A surveying instrument with adjustable surveying height includes a surveying instrument body 1 and a support frame. The support frame includes multiple sets of support legs 2 and a placement seat 3. The placement seat 3 is equipped with a moving mechanism for stably raising and lowering the surveying instrument body 1. The moving mechanism includes a fixed seat 4 and a housing 6. The fixed seat 4 is movably mounted on the placement seat 3. Multiple sets of housings 6 are fixedly mounted on the placement seat 3. A fixing bolt 5 for fixing the surveying instrument body 1 is rotatably mounted on the fixed seat 4. The surveying instrument consists of a surveying instrument body 1 and a support frame. The support frame includes multiple sets of support legs 2 and a placement seat 3 for supporting the surveying instrument body 1. The fixed seat 4 has a rotatable fixing bolt 5 for fixing the surveying instrument body 1 to the fixed seat. 4. Through the installation of the fixed base 4 and multiple sets of housings 6, when the motor 13 starts, it will drive the rotating shaft 11 to rotate. The gear 12 on the rotating shaft 11 will rotate accordingly, which in turn drives the gear 10 (and the lead screw 7) that meshes with it to rotate. Since the lead screw 7 and the lead screw nut 8 are threadedly engaged, the rotation of the lead screw 7 will cause the lead screw nut 8 to move linearly. Since the support rod 9 is fixedly connected to the lead screw nut 8, the linear movement of the lead screw nut 8 will drive the support rod 9 (and the fixed base 4 connected to it) to move linearly. When the support frame is providing stable support, the surveyor can also make stable height adjustments to the surveying instrument to adapt to different surveying needs, which helps to improve the efficiency and accuracy of surveying work.

[0019] Please see Figure 3 and Figure 4Inside the housing 6, a lead screw 7 is rotatably mounted, with a lead screw nut 8 meshing on it. A support rod 9 is fixedly mounted on the lead screw nut 8, and the top end of the support rod 9 is fixedly connected to the bottom of the fixed base 4. A gear 10 is fixedly mounted on the bottom end of the lead screw 7. Inside the housing 6, a rotating shaft 11 is rotatably mounted, with a gear 12 fixedly mounted on it, meshing with the gear 10. A motor 13 is fixedly mounted outside the housing 6, and the output end of the motor 13 is fixedly connected to one end of the rotating shaft 11. The housing 6 is a closed space used to house and protect the internal mechanical components. The lead screw 7 is a rotatable slender rod with threads on its surface, used to cooperate with the lead screw nut 8 to achieve linear motion or force transmission. The lead screw nut 8 is a nut that matches the threads on the lead screw 7. When the lead screw 7 rotates, the lead screw nut 8 moves along the axis of the lead screw 7. The top end of the support rod 9 is fixedly connected to the bottom of the fixed base 4, and the support rod 9 itself is connected to the lead screw nut 4 via a lead screw nut 8. The screw nut 8 is connected to the lead screw 7. Therefore, the rotation of the lead screw 7 will cause the support rod 9 (and the fixed seat 4 connected to it) to move linearly. The motor 13 is a power source to provide rotational power. Since the output end of the motor 13 is externally fixedly connected to one end of the rotating shaft 11, when the motor 13 starts, it will drive the rotating shaft 11 to rotate. When the motor 13 starts, it will drive the rotating shaft 11 to rotate, and the gear 12 on the rotating shaft 11 will rotate accordingly, thereby driving the gear 10 (and the lead screw 7) to rotate. Since the lead screw 7 and the lead screw nut 8 are threaded, the rotation of the lead screw 7 will cause the lead screw nut 8 to move linearly. Since the support rod 9 is fixedly connected to the lead screw nut 8, the linear movement of the lead screw nut 8 will drive the support rod 9 (and the fixed seat 4 connected to it) to move linearly. When the support frame is providing stable support, the surveyor can also make stable height adjustments to the surveying instrument to adapt to different surveying needs, which helps to improve the efficiency and accuracy of surveying work.

[0020] Working principle: The surveying instrument consists of a main body 1 and a support frame. The support frame includes multiple sets of support legs 2 and a mounting base 3 for supporting the main body 1. A rotatable fixing bolt 5 is located on the mounting base 4 to fix the main body 1 to the mounting base 4. Through the installation of the mounting base 4 and multiple sets of housings 6, when the motor 13 starts, it drives the rotating shaft 11 to rotate. The gear 12 on the rotating shaft 11 will rotate accordingly, thereby driving the meshing gear 10 (and the lead screw 7) to rotate. Since the lead screw 7 and the lead screw nut 8 are threadedly engaged, the rotation of the lead screw 7 will cause the lead screw nut 8 to rotate. Linear movement: Since the support rod 9 is fixedly connected to the lead screw nut 8, the linear movement of the lead screw nut 8 will drive the support rod 9 (and the fixed seat 4 connected to it) to move linearly. This allows the surveyor to make stable height adjustments to the surveying instrument while the support frame is providing stable support, adapting to different surveying needs and helping to improve the efficiency and accuracy of surveying work. The housing 6 is an enclosed space used to house and protect the internal mechanical components. The lead screw 7 is a rotatable slender rod with threads on its surface, used to cooperate with the lead screw nut 8 to realize linear motion or force transmission. The lead screw nut 8 is a... The screw nut 8 on screw 7 matches the thread. When screw 7 rotates, screw nut 8 moves along the axis of screw 7. The top of support rod 9 is fixedly connected to the bottom of fixed seat 4, and support rod 9 itself is connected to screw 7 through screw nut 8. Therefore, the rotation of screw 7 will cause linear movement of support rod 9 (and the fixed seat 4 connected to it). Motor 13 is a power source used to provide rotational power. Because the output end of motor 13 is fixedly connected to one end of shaft 11, when motor 13 starts, it will drive shaft 11 to rotate. When shaft 11 rotates, gear 12 on shaft 11 will rotate accordingly, which in turn drives gear 10 (and lead screw 7) to rotate. Since lead screw 7 and lead screw nut 8 are threadedly connected, the rotation of lead screw 7 will cause lead screw nut 8 to move linearly. Since support rod 9 is fixedly connected to lead screw nut 8, the linear movement of lead screw nut 8 will drive support rod 9 (and the fixed seat 4 connected to it) to move linearly. This allows surveyors to make stable height adjustments to the surveying instrument while the support frame is providing stable support, in order to adapt to different surveying needs and help improve the efficiency and accuracy of surveying work.
