Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying and mapping technology, and specifically relates to an engineering surveying instrument. Background Technology

[0002] Surveying refers to the determination, collection, and mapping of the shape, size, spatial location, and attributes of natural geographical elements or man-made structures on the earth's surface. Surveying begins with measurement. In engineering surveying, wheeled distance measuring instruments are often used. Currently, wheeled distance measuring instruments can only display the measured distance through a counter. However, often it's necessary to mark specific distance points while measuring. This requires another person to mark the points simultaneously, or the person measuring to stop and mark them, resulting in high labor intensity, high costs, wasted manpower, and reduced measurement efficiency. Furthermore, the handle height is fixed; if the height is unsuitable for people of different heights and arm lengths, it will cause fatigue for the surveyor, and since the distances to be measured are often long, this significantly increases the difficulty of the measurement. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an engineering surveying instrument that can simultaneously perform marking and has adjustable height.

[0004] This utility model is achieved through the following technical solution:

[0005] An engineering surveying instrument includes a roller, a counter connected to the side of the roller, and the counter connected to the bottom of a push rod. The instrument is characterized in that: the counter is hinged to one end of a powder tank, the other end of the powder tank is hinged to the bottom of a boom, the top of the boom is hinged to the front end of a control rod, the middle of the control rod is hinged to a push rod, and a top spring is connected between the rear end of the control rod and the top of the push rod.

[0006] Several valves are provided on the side of the powder tank.

[0007] The bottom of the push rod is hinged to the surface of the counter, and the lower part of the push rod is hinged to the support rod. The support rod is inserted into the support tube, and the support tube is hinged to the counter.

[0008] The support rod and support tube are respectively provided with screw holes, and fixing bolts are inserted into the screw holes.

[0009] The beneficial effects of this utility model are: it allows for marking at any time during the measurement process and can be used for drawing lines. At the same time, it is convenient for people of different heights to operate, reducing labor intensity and greatly improving work efficiency. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Appendix Figure 1It is a structural diagram of the utility model;

[0012] In the diagram, 1 is a roller, 2 is a counter, 3 is a push rod, 4 is a toner tank, 5 is a boom, 6 is a control lever, 7 is a top spring, 8 is a valve, 9 is a support rod, 10 is a support pipe, and 11 is a fixing bolt. Detailed Implementation

[0013] The attached figure shows a specific embodiment of this utility model. This embodiment includes a roller 1, a counter 2 connected to the side of the roller 1, the counter 2 connected to the bottom of a push rod 3, the counter 2 hinged to one end of a toner cartridge 4, the other end of the toner cartridge 4 hinged to the bottom of a boom 5, the top of the boom 5 hinged to the front end of a control rod 6, the middle of the control rod 6 hinged to the push rod 3, and a top spring 7 connected between the rear end of the control rod 6 and the top of the push rod 3. Several valves 8 are provided on the side of the toner cartridge 4. The bottom of the push rod 3 is hinged to the surface of the counter 2, and the lower part of the push rod 3 is hinged to a support rod 9. The support rod 9 is inserted into a support tube 10, which is hinged to the counter 2. Screw holes are respectively provided on the support rod 9 and the support tube 10, and fixing bolts 11 pass through the screw holes.

[0014] Using this engineering surveying instrument, when measuring distance, simply hold the push rod 3 to rotate the roller 1 forward, and the length distance can be obtained from the counter 2. When marking at one or more distances, lime powder or liquid ink is filled into the ink tank 4. When the counter 2 indicates that the desired marking location has been reached, pull the end of the control rod 6 upwards. The front end of the control rod 6 will swing downwards, pushing the boom 5 downwards. Since the ink tank 4 is hinged to the counter 2, it will rotate, thus pouring the lime or liquid ink into the ground to complete the marking. Then, release the end of the control rod 6 to return the ink tank 4 to a straight position. When the amount of lime or liquid ink in the ink tank 4 decreases, the valves 8 can be opened sequentially to allow the ink tank 4 to tilt at a small angle to pour out the lime or liquid ink, completing the marking. By continuously pulling the end of the control rod 6 upwards to continuously pour out lime from the ink tank 4, it can also be used for line marking. Pull out the fixing bolt 11, adjust the length of the support rod 9 extending into the support tube 10 so that the screw holes of the two are aligned, and then insert the fixing bolt 11 to adjust the height of the push rod 3 to achieve the most suitable height for the measuring personnel and reduce labor intensity.
