Description

Technical Field

[0001] This utility model relates to the field of surveying device technology, specifically a surveying device for surveying design. Background Technology

[0002] A roller rangefinder is a measuring device. It consists of a handle, a rangefinder wheel, and a reading device. A connecting rod is attached to the lower end of the handle, and a wheel frame is attached to the lower end of the connecting rod. The rangefinder wheel is mounted in the wheel frame.

[0003] The existing distance measuring wheel is manually controlled, and the path of the distance measuring wheel is prone to deviation, making it impossible to ensure that the distance measuring wheel is on a straight path, resulting in a decrease in distance measuring accuracy. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a surveying and design device to solve the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a surveying and design device, comprising a measuring wheel and a support assembly for mounting the measuring wheel, wherein a meter counter is provided on the measuring wheel, the meter counter is used to calculate the length traveled by the measuring wheel, the support assembly includes a support plate, a handle and a wheel frame, the measuring wheel is mounted on the wheel frame, and an opening is provided on the support plate, wherein a straight line auxiliary component is provided in the opening.

[0006] Preferably, the linear auxiliary component includes a rotating shaft, a first electric telescopic rod, and an auxiliary wheel. The rotating shaft is rotatably disposed at the opening, and the outer peripheral wall of the rotating shaft is fixedly connected to the first electric telescopic rod. The top of the first electric telescopic rod is rotatably connected to the auxiliary wheel.

[0007] Preferably, a second electric telescopic rod is also fixedly connected to the wheel frame, and a friction plate is fixedly connected to the end of the second electric telescopic rod. The axle on one side of the measuring wheel is inserted into the rotating groove of the wheel frame, and the friction plate is located in the rotating groove.

[0008] Preferably, the bottom of the support plate is fixedly connected to the wheel frame, the top of the support plate is fixedly connected to the handle, and the handle is provided with two electronic control buttons.

[0009] Preferably, the handle is provided with an anti-slip sleeve.

[0010] Preferably, a storage battery is disposed in the inner cavity at the top of the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the contact and limiting effect between the auxiliary wheel and the wall ensures that the measuring wheel can move in a straight line, improving the accuracy of distance measurement. When there is an obstacle in the path of the measuring wheel, the first electric telescopic rod is extended or retracted, thereby controlling the horizontal displacement of the measuring wheel. While overcoming the obstacle, it ensures that the measuring wheel's measurement path does not bend, guaranteeing measurement accuracy. The extension and retraction effect of the first electric telescopic rod can also adapt to the distance between the wall and the overall device, increasing the applicability.

[0012] Secondly, before the measuring wheel moves horizontally, the second electric telescopic rod is extended or retracted, causing the friction plate to rub against the shaft on one side of the measuring wheel. This limits the rolling of the measuring wheel during horizontal movement, further improving the accuracy of distance measurement. Attached Figure Description

[0015] 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.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0018] Example Please see Figure 1-3 This utility model provides a surveying and design device, including a measuring wheel 1 and a support assembly for mounting the measuring wheel 1. A meter counter 2 is provided on the measuring wheel 1, which is used to calculate the length traveled by the measuring wheel 1. The support assembly includes a support plate 3, a handle 301, and a wheel frame 302. The measuring wheel 1 is mounted on the wheel frame 302. An opening is provided on the support plate 3, and a linear auxiliary component 4 is provided in the opening. The linear auxiliary component 4 is used to assist the measuring wheel 1 in linear movement and improve the accuracy of distance measurement. The distance measurement principle of the measuring wheel 1 adopts the counting principle of the mature meter counter 2 in the prior art.

[0019] The linear auxiliary component 4 includes a rotating shaft 401, a first electric telescopic rod 403, and an auxiliary wheel 402. The rotating shaft 401 is rotatably disposed at the opening, and the outer peripheral wall of the rotating shaft 401 is fixedly connected to the first electric telescopic rod 403. The top of the first electric telescopic rod 403 is rotatably connected to the auxiliary wheel 402.

[0020] Specifically: Figure 2 In the middle, the auxiliary wheel 402 flips from the opening to a horizontal state. Holding the handle 301, the distance measuring wheel 1 is controlled to perform distance measuring work. At the same time, the auxiliary wheel 402 is in contact with the wall in the distance measuring space. Based on the design requirement that the wall is horizontal, the auxiliary wheel 402 moves horizontally along the wall, while the distance measuring wheel 1 moves in a straight line. Understandably, without the restraining effect of the auxiliary wheel 402 against the wall, the measuring wheel 1 is prone to serpentine movement, which leads to a decrease in measuring accuracy. Therefore, the restraining effect of the auxiliary wheel 402 against the wall improves the accuracy of measuring distance. When there is an obstacle on the straight-line path of the measuring wheel 1, the first electric telescopic rod 403 is extended or retracted, thereby controlling the horizontal displacement of the measuring wheel 1. While passing over the obstacle, it ensures that the measuring path of the measuring wheel 1 does not bend, thus guaranteeing measurement accuracy. The extension and retraction effect of the first electric telescopic rod 403 can also adapt to the distance between the wall and the overall device, thus improving the applicability.

[0021] A second electric telescopic rod 5 is also fixedly connected to the wheel frame 302. A friction plate 501 is fixedly connected to the end of the second electric telescopic rod 5. The axle column on one side of the ranging wheel 1 is inserted into the rotating groove 502 of the wheel frame 302, and the friction plate 501 is located in the rotating groove 502.

[0022] Specifically: Before the measuring wheel 1 moves horizontally, the second electric telescopic rod 5 is controlled to extend and retract, so that the friction plate 501 rubs against the shaft column on one side of the measuring wheel 1, thereby limiting the rolling of the measuring wheel 1 during horizontal movement and further improving the accuracy of distance measurement.

[0023] The bottom of the support plate 3 is fixedly connected to the wheel frame 302, and the top of the support plate 3 is fixedly connected to the handle 301. Two electronic control buttons 6 are provided on the handle 301.

[0024] The handle 301 is provided with an anti-slip sleeve 303.

[0025] A storage battery is installed in the inner cavity at the top of the bracket plate 3.

[0026] Electrical equipment such as the electric control button 6, the storage battery, the first electric telescopic pole 403, and the second electric telescopic pole 5 are connected by wiring.
