Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping, and more specifically, to a measuring rod for surveying and mapping. Background Technology

[0002] A leveling rod is a type of leveling rod. Early leveling rods were mostly made of wood, which were heavy and had limited length, making them inconvenient to carry during measurement. Later, they were gradually made of lightweight and high-strength materials such as aluminum alloy. They adopted a tower-shaped retractable design, which made them easy to pull out during use and greatly increased the range of single elevation measurements. The length is generally 5m, and they can be retracted when carried. Because of its tower-like shape, it is often called a leveling rod.

[0003] Because the scaling height of the aluminum alloy leveling rod has been increased, it is very inconvenient to adjust due to its length. It requires manual tilting to complete the scaling or multiple people working together. The ruler plate is easily damaged by moisture or mud, and it is difficult to ensure that the screws and springs are dry, which can easily lead to loosening, rusting and jamming. In order to facilitate operation and improve the durability of the leveling rod, a new leveling rod for measurement and mapping is proposed to solve the above problems. Utility Model Content

[0004] To overcome the limitations of existing technologies, such as the long telemeter height, which makes single-person operation difficult and the inability to maintain stability on muddy surfaces, thus affecting measurement accuracy, this utility model provides a surveying and mapping telemeter, including a base. Two flipping components are fixedly installed on the top of the base, and a mounting base is fixedly connected to the opposite side of the two flipping components. A telemeter body is inserted into the mounting base. A lifting threaded seat is fixedly installed on the top of the base, and a grounding component is installed in the internal thread of the lifting threaded seat. A positioning component is fixedly installed on the inner wall of the mounting base, and a vertical insertion rod is fixedly installed at the bottom of the mounting base.

[0005] The grounding assembly includes a drilling screw, a drill bit is fixedly installed at the bottom of the drilling screw, and an adjusting handle is fixedly installed at the top of the drilling screw. A positioning groove is provided at the top of the adjusting handle.

[0006] A through groove is provided at the center of the base, and the drilled screw is located inside the through groove.

[0007] Preferably, both of the flipping components include a pivot seat, and a pivot rod is movably mounted on the opposite side of each of the two pivot seats, and the opposite side of each of the two pivot rods is fixedly connected to a mounting base.

[0008] The flip assembly is used to adjust the angle of the mounting base.

[0009] Preferably, the positioning component includes a threaded tube, which is fixedly installed on the inner wall of the mounting base. An adjusting screw is installed on the internal thread of the threaded tube. A positioning rod is fixedly installed at one end of the adjusting screw, and the other end of the adjusting screw is movably connected to the inside of the bearing. A positioning chuck is fixedly installed on the outer wall of the bearing.

[0010] The positioning component is used to clamp and fix the ruler inside the mounting base.

[0011] Preferably, the positioning clamp is located inside the mounting base, the positioning clamp is C-shaped, the inner wall of the positioning clamp is provided with an anti-slip rubber pad, and the inner wall of the positioning clamp is in contact with the ruler body.

[0012] Preferably, the shape of the positioning rod is adapted to the positioning groove opened at the top of the adjusting handle.

[0013] When the mounting base and the ruler are at a longitudinal angle, rotating the adjustment handle upwards will allow it to engage with the positioning rod to form a position, preventing the ruler from touching the bottom due to its weight.

[0014] Preferably, the shape of the vertical insert is adapted to the positioning groove opened at the top of the adjusting handle.

[0015] When the mounting base and the ruler are at a vertical angle, rotating the adjustment handle to rise allows it to be inserted into the vertical insertion rod for positioning, eliminating the need for manual support from staff.

[0016] Preferably, the bottom of the base has two grooves.

[0017] Preferably, the height between the bottom wall of the base and the mounting base is 30 cm.

[0018] It can be used to increase the measurement height range of the ruler.

[0019] Beneficial effects:

[0020] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0021] (1) By setting a mounting base for mounting the ruler, and installing flipping components on both sides of the mounting base, when the staff is scaling the ruler, they can rotate the mounting base to the longitudinal angle to make the ruler flat and lower its height, thus facilitating the scaling of the ruler. After the ruler is scaled, the mounting base is flipped again to make the ruler vertical, so that the height can be measured. A vertical insertion rod is set at the bottom of the mounting base, which can be inserted with the adjustment handle to form a limit. No additional personnel are needed to support it, and a self-locking effect is achieved. This allows the staff to independently operate equipment such as a level to observe the height of the object being measured. The measurement work can be completed by one person, which has good convenience.

[0022] (2) The bottom of the base has a groove to better adapt to uneven muddy road sections. At the same time, a lifting thread seat is installed on the top of the base. The lifting thread seat can be adjusted in conjunction with the grounding component. When the drilling screw is rotated and lowered, the drill bit goes deep into the ground to improve stability, thereby ensuring that the measuring rod can still maintain stability and improve measurement accuracy on complex ground. In addition, there is a certain height difference between the base and the mounting seat, which can also increase the measurement height range of the ruler. On flat road surfaces, the ruler can be separated from the mounting seat after the ruler is adjusted, which has both practicality and convenience. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0033] like Figures 1 to 6 As shown, a surveying and mapping leveling rod includes a base 1. Two flipping components 2 are fixedly mounted on the top of the base 1. A mounting base 3 is fixedly connected to the opposite side of each of the two flipping components 2. Each flipping component 2 includes a pivot seat 20. A pivot rod 21 is movably mounted on the opposite side of each of the two pivot seats 20. The opposite side of each pivot rod 21 is fixedly connected to the mounting base 3. A leveling rod 4 is inserted into the interior of the mounting base 3. A lifting threaded seat 5 is fixedly mounted on the top of the base 1. A grounding component 6 is threaded into the interior of the lifting threaded seat 5. A positioning component 7 is fixedly mounted on the inner wall of the mounting base 3. A vertical insertion rod 31 is fixedly mounted on the bottom of the mounting base 3. The grounding component 6 includes a drilled screw 60. The bottom of the drilled screw 60... A drill bit 61 is fixedly installed, and an adjusting handle 62 is fixedly installed on the top of the drilling screw 60. The top of the adjusting handle 62 has a positioning groove, and a through groove is opened in the center of the base 1. The drilling screw 60 is located inside the through groove. The shape of the positioning rod 72 is adapted to the positioning groove opened on the top of the adjusting handle 62. The shape of the vertical insertion rod 31 is adapted to the positioning groove opened on the top of the adjusting handle 62. The flipping component 2 is used to drive the mounting base 3 to flip. When measuring, the ruler 4 is vertically inserted into the interior of the mounting base 3. The height between the bottom wall of the base 1 and the mounting base 3 is 30 cm, which can increase the height range measured by the ruler 4. At the same time, it can cooperate with the base 1 to ensure that the ground is flat and thus reduce the error during measurement.

[0034] It should be noted that there is no need to raise the measuring height to obtain the actual height; the actual height can be determined by subtracting 30 centimeters from the height measured on ruler 4.

[0035] In addition, when the ruler body 4 is in a vertical state, the vertical insertion rod 31 at the bottom of the mounting base 3 will be inserted into the positioning groove at the top of the adjusting handle 62, thereby fixing the mounting base 3 to ensure stability. When it is necessary to adjust the scaling of the ruler body 4, the mounting base 3 can be rotated to a longitudinal angle by flipping component 2, so that the height of the ruler body 4 is reduced, making it convenient for the staff to make adjustments. When the mounting base 3 is at a longitudinal angle, the positioning rod 72 will be inserted into the positioning groove of the adjusting handle 62.

[0036] The positioning component 7 includes a threaded tube 70, which is fixedly installed on the inner wall of the mounting base 3. An adjusting screw 71 is installed inside the threaded tube 70. A positioning rod 72 is fixedly installed at one end of the adjusting screw 71, and the other end of the adjusting screw 71 is movably connected to the inside of the bearing 74. A positioning chuck 73 is fixedly installed on the outer wall of the bearing 74. The positioning chuck 73 is located inside the mounting base 3 and is shaped like a "C". The inner wall of the positioning chuck 73 is provided with an anti-slip pad. The inner wall of the positioning chuck 73 fits against the ruler 4. The bottom of the base 1 has two grooves 10. When measuring on muddy roads, it is difficult to ensure the stability of the ruler 4. Therefore, the drilling screw 60 can be rotated and displaced by rotating the adjusting handle 62, and then the tip of the drill bit 61 can be inserted into the muddy road. The grooves 10 at the bottom of the base 1 can better adapt to uneven and complex road conditions.

[0037] In addition, the shape of the positioning chuck 73 can fit well with the bottom of the ruler 4 for clamping, thereby ensuring that the ruler 4 will not fall off when it is rotated with the mounting base 3.

[0038] Working principle: After determining the measurement position, rotate the adjusting handle 62 to drive the drilling screw 60 to drive the drill bit 61 into the muddy ground to ensure the stability of the base 1. At the same time, rotate the mounting base 3 to the longitudinal angle by flipping component 2, and scale the ruler 4 to the maximum state. Then flip the mounting base 3 to make the ruler 4 vertical. Rotate the drilling screw 60 in the opposite direction to raise the adjusting handle 62 and insert it into the vertical insertion rod 31 at the bottom of the mounting base 3 to form a positioning, ensuring that the drill bit 61 is partially stuck in the ground. Finally, the height position of the measured object displayed on the ruler 4 is observed to obtain the data.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
