Description

Technical Field

[0001] This utility model relates to a construction cost measurement device that can be used with mobile devices. Background Technology

[0002] A distance measuring wheel is a commonly used surveying tool, widely applied in land surveying, engineering surveying, road construction, and other fields. A traditional distance measuring wheel typically consists of a wheel, a counter, and a handle, calculating distance by measuring the number of wheel rotations. However, traditional distance measuring wheels are limited in function, only capable of distance measurement, and cannot meet users' needs for visualization and traceability of measurement data.

[0003] It is common for cost estimators to deliberately walk in a crooked manner when measuring distances to increase the calculated distance, or to spin the measuring wheel idle to increase the distance, thereby inflating the estimated price of the project and receiving kickbacks.

[0004] To avoid this situation, we designed a construction cost measurement device that can be used in conjunction with mobile devices to capture video during distance measurement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a construction cost measurement device that can be used with mobile devices to shoot videos during distance measurement.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A construction cost measuring device that can be used with a mobile device includes a measuring wheel and an electronic counter that works with the measuring wheel. A handle is mounted on the electronic counter, and a self-hanging device is mounted by rotating the handle. A clamping device for clamping the mobile device is mounted on the upper end of the self-hanging device.

[0008] Preferably, the self-closing device includes a shaft and a rotating ring installed outside the shaft. A bearing is fitted between the rotating ring and the shaft. An extension rod is provided at the bottom of the rotating ring. A self-closing block is integrally formed at the bottom of the extension rod. A connecting pipe is provided at the top of the rotating ring. The connecting pipe is coaxial with the extension rod. The clamping device is installed through the connecting pipe.

[0009] Preferably, the self-clinching block is located on the side of the measuring wheel that is furthest from the electronic counter.

[0010] Preferably, a base plate is welded to the bottom of the self-hanging block.

[0011] Preferably, the clamping device includes a universal ball, a ball rod, a fixed seat, a movable seat, a movable rod, a limiting screw, a limiting nut, and a tube cap. The ball rod is injection molded on the diameter line of the universal ball. The fixed seat is screwed to the ball rod. The movable seat and the movable rod are injection molded integrally. The lower end of the movable rod passes through the limiting nut and is inserted into the ball rod. The lower end of the movable rod is screwed into the limiting screw, which limits the upward movement of the movable rod. A spring is sleeved on the movable rod, and the spring acts between the limiting nut and the limiting screw. The connecting pipe has a spherical hole, and the universal ball is embedded in the spherical hole. The tube cap is threaded with the connecting pipe and limits the upward movement of the universal ball. Clamping plates are provided opposite to each other on the outer walls of the fixed seat and the movable seat.

[0012] Preferably, a damping washer is embedded inside the tube cover, and the damping washer acts on the universal ball.

[0013] Preferably, anti-slip pads are fixed on the opposite surfaces of the two clamping plates, and anti-slip grooves are injection molded on the surface of the anti-slip pads.

[0014] The beneficial effects of this utility model are:

[0015] This device can mount a mobile device by using a self-hanging device and a clamping device. The device's camera records video and archives the entire distance measurement process. This allows for retrospective analysis and helps determine if there was any falsification if there are discrepancies in the later cost estimation.

[0016] This device has a simple structure and low cost, making it suitable for widespread use. Attached Figure Description

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] See Figure 1 The illustrated construction cost measuring device includes a measuring wheel 1 and an electronic counter 2 that works with the measuring wheel 1. A handle 3 is mounted on the electronic counter 2, and a self-hanging device 4 is rotatably mounted on the handle 3. A clamping device 5 for clamping the mobile device is mounted on the upper end of the self-hanging device 4.

[0027] In the above technical solution, the number of rotations of the measuring wheel 1 is calculated by the electronic counter 2, and the distance can be calculated by multiplying the number of rotations by the outer circumference of the measuring wheel.

[0028] The clamping device 5 can be used to clamp shooting equipment, such as mobile phones. The self-hanging device 4 can hold the position of the clamping device 5. The shooting angle can be adjusted by adjusting the angle of the clamping device 5.

[0029] By using the above methods, the entire distance measurement process is filmed and archived to prevent situations where costs are inflated to obtain kickbacks.

[0030] See Figure 1 and Figure 2 As shown, the self-falling device 4 includes a shaft 41 and a rotating ring 42 installed outside the shaft 41. A bearing 4443 is fitted between the rotating ring 42 and the shaft 41. An extension rod 43 is provided at the bottom of the rotating ring 42. A self-falling block 44 is integrally formed at the bottom of the extension rod 43. A connecting pipe 45 is provided at the top of the rotating ring 42. The connecting pipe 45 is coaxial with the extension rod 43. The clamping device 5 is installed through the connecting pipe 45.

[0031] In the above technical solution, the weight of the self-hanging block 44 is greater than 600g. The lever arm is extended by the extension rod 43 so that the extension rod 43 is in a vertical state under the action of gravity, ensuring the accuracy of the shooting angle.

[0032] See Figure 1 As shown, the self-clinching block 44 is located on the side of the measuring wheel 1 that is away from the electronic counter 2.

[0033] This structure is achieved by extending the shaft 41. By extending the length of the shaft 41, the self-hanging device 4 is located on the other side of the measuring wheel, which allows the measuring wheel to balance the weight of the electronic counter when it is pushed, making the push more stable.

[0034] See Figure 2 As shown, a base plate 444 is welded to the bottom of the self-hanging block 44.

[0035] The base plate 444 is designed to limit the rotation of the handle by contacting the ground.

[0036] See Figure 3As shown, the clamping device 5 includes a universal ball joint 51, a ball rod 52, a fixed base 53, a movable base 54, a movable rod 55, a limiting screw 56, a limiting nut 57, and a pipe cap 58. The ball rod 52 is injection molded on the ball diameter line of the universal ball joint 51. The fixed base 53 is screwed to the ball rod 52. The movable base 54 and the movable rod 55 are injection molded integrally. The lower end of the movable rod 55 passes through the limiting nut 57 and is inserted into the ball rod 52. The lower end of the movable rod 55 is screwed into the limiting screw 56. 6. The limiting screw 56 limits the upward movement of the movable rod 55. A spring 59 is sleeved on the movable rod 55, and the spring 59 acts between the limiting nut 57 and the limiting screw 56. The connecting pipe 45 has a spherical hole 4441, and the universal ball 51 is embedded in the spherical hole 4441. The pipe cover 58 is threadedly engaged with the connecting pipe 45 and limits the upward movement of the universal ball 51. Clamping plates 551 are provided opposite to each other on the outer walls of the fixed seat 53 and the movable seat 54.

[0037] In the above technical solution, by pulling the movable rod 55 upward, the distance between the upper and lower clamping plates 551 is widened, thereby completing the clamping of mobile devices such as mobile phones.

[0038] The omnidirectional ball can rotate, and after rotation, the shooting angle of the mobile device can be adjusted. At the correct shooting angle, a portion of the rangefinder wheel will be exposed in the lens.

[0039] This allows us to determine whether the vehicle is traveling around bends or whether the measuring wheel is spinning freely.

[0040] See Figure 3 As shown, a damping washer 588 is embedded inside the tube cover 58, and the damping washer 588 acts on the universal ball 51.

[0041] This technical solution can increase rotational damping for the omnidirectional ball, especially on uneven ground, which can reduce the displacement of the omnidirectional ball 51 and make the shooting of mobile devices more stable.

[0042] See Figure 3 As shown, anti-slip pads 552 are fixed on the opposite surfaces of the two clamping plates 551, and anti-slip grooves are formed on the surface of the anti-slip pads by injection molding.

[0043] In the above technical solution, the anti-slip pad 552 can increase the anti-slip ability and enhance the fixation effect on the mobile device.
