Description

Technical Field

[0001] The utility model relates to a surveying and mapping device, in particular to a distance measuring wheel for national land space planning, belonging to the technical field of national land space planning. Background Art

[0002] Measuring wheels, also known as mechanical measuring vehicles, are widely used in various occasions requiring precise measurement due to their high-quality precision design, compactness, lightness and durability. In surveying and mapping work that requires precise measurement and evaluation, measuring wheels can help measure any distance on a plane, ensuring the accuracy and efficiency of the measurement.

[0003] However, when the existing measuring wheel cannot be conveniently folded and stored during use, it becomes more difficult for operators to carry and store it after use, especially in environments with limited space, such as a car trunk or a work site, where the measuring wheel may take up too much space, thereby limiting the carrying of other tools or items. Utility Model Content

[0004] The purpose of the utility model is to provide a distance measuring wheel for land space planning in order to solve the above-mentioned problem. The sliding rod slides along the folding rod to squeeze the telescopic spring, so that it drives the clamping rod to slide out of the mounting block. The folding rod is rotated, so that the connecting block drives the connecting shaft to rotate along the fixed seat, thereby facilitating the folding rod to be folded and stored.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme. A distance measuring wheel for land space planning comprises a rubber handle, a folding rod is fixedly installed on the rubber handle, a limiting mechanism is slidably installed on the folding rod, the limiting mechanism comprises an anti-slip sleeve and a sliding rod, the folding rod is slidably connected with the sliding rod, the sliding rod is bonded with an anti-slip sleeve, a telescopic spring is sleeved on the folding rod, the telescopic spring contacts the sliding rod, a connecting block is fixedly installed on the folding rod, a rotating shaft is fixedly installed on the connecting block, the rotating shaft is rotatably connected to a fixed seat, a mounting block and an aluminum alloy pipe rack are fixedly connected to the fixed seat, a clamping rod is fixedly connected to the sliding rod, the clamping rod is clamped and connected to the mounting block, a measuring mechanism is installed on the aluminum alloy pipe rack, and a marking mechanism is rotatably provided on the measuring mechanism.

[0006] Preferably, a plurality of the clamping rods are equidistantly mounted in a ring shape on the end of the slide bar close to the connecting block, and the slide bar abuts against the top end of the connecting block.

[0007] Preferably, the connection block is rotatably connected to the fixing seat, and the diameter of the fixing seat is larger than the diameter of the aluminum alloy pipe rack.

[0008] Preferably, the diameter of the folding rod is smaller than the diameter of the sliding rod, and the length of the clamping rod is greater than the length of the mounting block.

[0009] Preferably, the length of the folding rod is smaller than the length of the aluminum alloy tube rack, and the diameter of the folding rod is equal to the diameter of the aluminum alloy tube rack.

[0010] Preferably, the measuring mechanism comprises a base plate and a positioning tube, the aluminum alloy tube rack is fixedly connected with the positioning tube, the base plate is fixedly mounted on the positioning tube, the base plate is fixedly connected with a counter, and the base plate is rotatably connected with a distance measuring wheel body and a metal bracket.

[0011] Preferably, the positioning tube is located at the bottom end of the aluminum alloy tube rack, and the diameter of the aluminum alloy tube rack is smaller than the diameter of the positioning tube.

[0012] Preferably, the distance measuring wheel body is located on a side wall of the bottom plate away from the metal bracket, and the metal bracket is located at the bottom end of the bottom plate.
