Description

Technical Field

[0001] The utility model relates to a distance meter for engineering cost, in particular to a distance meter for engineering cost applied in the field of measuring instruments. Background Art

[0002] A wheeled distance meter is a type of distance meter that is primarily designed and manufactured for outdoor distance measurement. It is suitable for a variety of ground conditions, including grasslands, hillsides, rugged construction sites, etc. The wheeled distance meter has a long measurement distance and a clear and accurate digital display system. Therefore, it is widely used in the measurement and evaluation of road engineering, pipeline laying engineering, professional surveying and mapping, and other construction operations. The wheeled distance meter is large and not easy to fold.

[0003] The Chinese patent CN219656840U specification discloses a wheeled distance meter, which relates to the technical field of distance meters, including an electronic counter, a distance measuring wheel and a display. The wheeled distance meter is easy to fold, so that the device is easy to carry, and the wheeled distance meter is easy to adjust in height according to the height of the user.

[0004] The Chinese patent CN215114315U specification discloses a wheeled distance meter for construction. The wheeled distance meter for construction comprises: a handle, on which a telescopic mechanism, a distance measuring mechanism and a supporting mechanism are arranged; the wheeled distance meter for construction provided by the utility model has the advantages that the length of the handle can be adjusted according to the user, the vehicle can be parked midway, and the legs can be folded.

[0005] During the use of the existing wheeled distance meter for engineering cost, due to the long measuring path, when the middle part of the wheeled distance meter stops, it is not convenient to immediately support and temporarily fix it, and manual intervention is required. Therefore, it is necessary to design a wheeled distance meter for engineering cost with a support pole function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that during the use of the existing wheeled distance meter for engineering cost, due to the long measuring path, when the middle part of the wheeled distance meter is stopped, it is not convenient to be immediately supported and temporarily fixed.

[0007] In order to solve the above problems, the utility model provides a distance meter for engineering cost, including a forward wheel, a vertical rod is installed on the upper right side of the forward wheel, a measuring device is fixedly connected to the right side of the forward wheel, a U-shaped frame is installed on the outer end of the forward wheel of the vertical rod, a pair of side support bracket bars are fixedly connected to the outer side of the lower end of the U-shaped frame, a handrail is fixedly connected to the upper end of the vertical rod, a tilting handle is rotatably connected to the lower end of the handrail, and a spring is fixedly connected between the tilting handle and the handrail.

[0008] In the above-mentioned distance meter for engineering cost, when using this scheme, the handgrip can be held by hand and the tilting handle can be squeezed at the same time. When squeezing, the spring is compressed, and the semi-arc ring lifts the two side support brackets to make them away from the ground, so that the forward wheel can be smoothly moved forward. When the forward wheel stops using, the handgrip is released and the tilting handle turns downward. After the two side support brackets are tilted synchronously, they can be supported horizontally with the ground. The parking method is quick, which is conducive to ensuring the accuracy of subsequent distance measurement.

[0009] As a further improvement of the present application, a semi-arc ring is fixedly connected to the lower end of the inclined handle, and a connecting wire is connected between the semi-arc ring and the side support bracket bar.

[0010] As a further improvement of the present application, one end of the side support bar away from the U-shaped frame is fixedly connected with a sharp corner.

[0011] As a further improvement of the present application, a rotating connecting shaft is installed in the middle of the vertical rod.

[0012] As another improvement of the present application, a pair of connecting horizontal bars are fixedly connected to the rear end of the forward wheel, and a rear arc guard plate is fixedly connected to the rear end of the two connecting horizontal bars.

[0013] As another improved supplement of the present application, the rear arc guard plate is located at the rear side of the forward wheel, and a slotted strip is provided at the upper end of the U-shaped frame.

[0014] As another improved supplement of the present application, the inner end of the slotted strip is slidably connected with a scraper plate, which extends above the forward wheel and cooperates with the scraper plate.

[0015] In summary, when using the present invention, the handgrip can be held by hand and the tilting handle can be squeezed at the same time. When squeezing, the spring is compressed, and the semi-arc ring lifts the two side support bracket bars to make them away from the ground, so that the forward wheel can be smoothly advanced. The displacement distance of the forward wheel is measured and calculated by a measuring instrument, and the value of the actual distance required for the engineering cost can be obtained. When the forward wheel stops being used, the tilting handle turns downward after the handgrip is released, and the spring rebounds to make the connecting wire restore the side support bracket bar to a downwardly rotating state. After the two side support bracket bars are tilted synchronously, they can be supported horizontally with the ground, so that the forward wheel remains in a stable and stopped state. It is easy to use and has a quick parking method, which is conducive to ensuring the accuracy of subsequent distance measurements. A scraper plate cooperating with the forward wheel is also provided on the U-shaped frame. The scraper plate removes dust and mud attached to the forward wheel, which is conducive to ensuring the smooth movement of the forward wheel. BRIEF DESCRIPTION OF THE DRAWINGS
