[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] Example

[0025] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a housing construction engineering cost measurement device;

[0026] A rectangular groove 4 is provided at the inner end of the measuring instrument body 1, a first connecting rod 5 is clamped and installed at the inner end of the rectangular groove 4, a second connecting rod 6 is clamped and installed at the inner end of the first connecting rod 5, a control screen 7 is installed at the inner end of the second connecting rod 6 through a damping shaft, a disc 8 is rotatably installed at the lower end of the measuring instrument body 1, and the disc 8 is fixedly installed at the upper end of the upper support plate 2, so that the display angle and extension distance of the control screen 7 can be adjusted according to the usage, so as to facilitate viewing and inputting of data, and bring convenience to measurement;

[0027] The inner end of the upper support plate 2 is threadedly connected with a threaded screw 9, and the lower end of the threaded screw 9 is rotatably mounted with a lower support plate 11. The upper support plate 2 is snap-fitted and mounted on the inner end of the lower support plate 11, so as to facilitate height adjustment;

[0028] The inner end of the base 3 is threadedly connected with a threaded rod 13, the lower end of the threaded rod 13 is clamped with a fixed caster 15, and the outer end of the threaded rod 13 is threadedly connected with a locking nut 14. The outer end of the threaded rod 13 is tightly fitted on the upper surface of the base 3. The upper end of the base 3 is fixedly installed with a turning handle 10, which is arranged on the outer side of the measuring instrument body 1. The inner end of the base 3 is provided with a control point observation port 12, which is arranged on the lower side of the measuring instrument body 1. The fixed casters 15 are arranged in four groups at the four corners of the base 3, which are suitable for different ground surfaces and can be easily moved.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, when the housing construction project cost measuring device is used, the device is moved to the desired location by rotating the fixed caster 15, and the height of the measuring instrument body 1 is adjusted. The threaded screw 9 is rotated by the turning handle 10. When the threaded screw 9 is rotated, the upper support plate 2 is engaged with the inner end of the lower support plate 11, so that the threaded screw 9 can only move up and down and cannot rotate. When the threaded screw 9 drives the disc 8 to adjust to a suitable height, the turning handle 10 can be stopped, and the threaded rod 13 can be adjusted according to the flatness of the ground. During the adjustment, the locking nut 14 is loosened upwards, and then the threaded rod 13 is rotated. The lower end of the threaded rod 13 rotates at the upper end of the fixed caster 15, so that the threaded rod 13 drives the fixed caster 15 to move upward or downward to level the base 3. When the adjustment of the threaded rod 13 is completed, the locking nut 14 is tightened to reinforce the threaded rod 13.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the light spot is then projected onto the control point on the lower side of the control point observation port 12, and the measuring instrument body 1 is adjusted. When inputting the measured value or viewing the value through the control screen 7, the control screen 7 can be pulled out from the inner end of the rectangular slot 4 and the angle can be adjusted. When the control screen 7 is pulled out, the second connecting rod 6 slides outward at the inner end of the first connecting rod 5, and then the angle of the control screen 7 is adjusted through the damping shaft, so that the control screen 7 is adjusted to an angle that is convenient for viewing, so as to avoid the screen being exposed to the light and causing unclear viewing when outdoors due to sunlight. When the control screen 7 is not in use, the second connecting rod 6 and the first connecting rod 5 can be pulled out and stretched, so that the front of the control screen 7 can be rotated to the direction toward the rectangular slot 4, and then the second connecting rod 6 and the first connecting rod 5 can be retracted to protect the control screen 7. The above completes a series of operations of the housing construction project cost measuring device. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
