[0002] Project cost refers to the construction costs that constitute the estimated or actual expenditure of the project during the construction period. The three elements of project cost are quantity, price, and fee. "Quantity" is the primary work of project cost, and measuring tools are indispensable equipment. Among them, tape measures are the most widely used in indoor and outdoor measurements of project cost, and are usually used to measure the length, distance, height, etc. of different buildings. Tape measures are also available in different types according to different measuring lengths, such as regular tape measures for short distances within 5 meters, while stand-type tape measures are mostly used for long distance measurements of dozens of meters.

[0003] Existing stand-type measuring tapes usually consist of a cross-structured mounting frame, measuring tapes of different materials, a rotating shaft and a crank handle. The measuring tape is rolled up on the rotating shaft. The measuring tape is pulled out when measuring, and the crank handle is turned when rolling up. However, in actual applications, this type of stand-type measuring tape is prone to dirt and water stains adhering to the measuring tape due to the complex environment. If it is not cleaned, the stand-type measuring tape is prone to corrosion and jamming when rolling up. At the same time, manually rotating the crank handle is very time-consuming and labor-intensive when measuring long distances. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0024] Example 1

[0025] A distance measuring tool described in this embodiment includes a mounting frame 1 of a cross-shaped structure, a rotating shaft 7 is horizontally arranged in the mounting frame 1, a measuring tape 4 is wound on the rotating shaft 7, one end of the rotating shaft 7 independently passes through the left side wall of the mounting frame 1 and is fixed with a first mounting plate 6, and the other end independently passes through the right side wall of the mounting frame 1 and is fixed with a second mounting plate 18, the rotating shaft 7, the first mounting plate 6 and the second mounting plate 18 are overall in an "H"-shaped structure, and rotating the first mounting plate 6 and the second mounting plate 18 can rotate the rotating shaft 7, and further drive the measuring tape 4 on the measuring tape 4 to be wound up or released, thereby achieving the purpose of winding up the released measuring tape 4 by rotating the first mounting plate 6 and the second mounting plate 18;

[0026] The first mounting plate 6 is provided with a crank 3 for manually rotating the first mounting plate 6. The first mounting plate 6 is rotated by the crank 3 to drive the rotating shaft 7 to rotate, so that the released measuring tape 4 can be manually retracted when measuring a short distance. Figure 1 and Figure 2 As shown, a fixing seat 5 is fixed to the left side wall of the first mounting plate 6, and one end of the crank handle 3 is hinged on the fixing seat 5, wherein the fixing seat 5 is composed of two connecting blocks, one end of the crank handle 3 is hinged between the two connecting blocks, and the other end of the crank handle 3 is installed with a toggle block that is rotatably matched therewith, and the toggle block is located on the side of the crank handle 3 facing away from the mounting frame 1. When in use, it is more convenient and labor-saving to rotate the crank handle 3 by pinching the toggle block, and at the same time, the crank handle 3 can be swung to make the toggle block face the mounting frame 1, thereby preventing the toggle block from hitting the user when releasing the measuring tape 4;

[0027] A housing 16 is provided on the right side of the mounting frame 1, and a motor 15 is installed in the housing 16. The power output end of the motor 15 independently passes through the housing 16 and is connected to a square block 17. A square groove for inserting the square block 17 is provided on the right side wall of the second mounting plate 18 (in this embodiment, the housing 16, the motor 15 and the square block 17 constitute the driving assembly for automatically rotating the second mounting plate 18 as a whole. In actual application, the motor 15 can be a motor with a gear reducer, a small servo motor, etc.) In this embodiment, the square block 17 is inserted into the corresponding square groove, and then the motor 15 is started to drive the square block 17 to rotate, thereby driving the second mounting plate 18 to drive the rotating shaft 7 to rotate, so that the released tape measure 4 can be automatically rolled up during long-distance measurement, thereby reducing the labor intensity of the staff;

[0028] like Figure 1 As shown, a ring block 13 is fixed to the right side wall of the mounting frame 1, a second mounting plate 18 is located inside the ring block 13, a plug block 14 of a ring structure is fixed to the left side wall of the housing 16, and a ring groove for clamping the plug block 14 is provided on the right side wall of the ring block 13. By plugging the plug block 14 into the ring groove of the ring block 13, the housing 16 can be detachably mounted on the mounting frame 1, so that it is easy to carry and can be quickly installed after long-distance measurement so that the released tape measure 4 is automatically retracted into the mounting frame 1; in actual application, the plug block 14 can be a ring structure or an arc structure, and when the plug block 14 is an arc structure, there are several plug blocks 14, and the several plug blocks 14 are distributed in a ring shape; as shown in FIG. Figure 1 As shown, the housing 16 is a shell-like structure without a left side wall, the motor 15 is installed in the housing 16 and has a self-contained speed reduction mechanism, and the power output end (output shaft) of the motor 15 faces the mounting frame 1;

[0029] like Figure 1 indivual Figure 2 As shown, a mounting groove 8 communicating front and rear is fixed at the lower end of the mounting frame 1, and the zero scale end of the measuring tape 4 is located in the mounting groove 8, so that the measuring tape 4 will pass through the mounting groove 8 whether it is being wound or measured;

[0030] A hard sponge 11 is fixed to the inner bottom of the mounting groove 8, the zero scale end of the measuring tape 4 is in contact with the top of the hard sponge 11, a scraper 9 for pressing the measuring tape 4 onto the hard sponge 11 is provided above the hard sponge 11, a hinge seat 12 is fixed to the top of the mounting groove 8, the upper end of the scraper 9 is hinged to the hinge seat 12 and cooperates with the hinge seat 12 to swing back and forth (in this embodiment, the hard sponge 11, the scraper 9 and the hinge seat 12 constitute the cleaning component for cleaning the measuring tape 4 as a whole, which can also be used in actual application) A hard sponge 11 is fixed to the inner top and the inner bottom of the installation groove 8, and a scraper 9 attached to the measuring tape 4 is fixed to the front side walls of the two hard sponges 11. In this embodiment, the measuring tape 4 is pressed against the hard sponge 11 by the scraper 9. Then, when the measuring tape 4 is rolled up, the mud and the like on the measuring tape 4 will be scraped off by the scraper 9, and the water stains adhered to the measuring tape 4 will be absorbed by the hard sponge 11, thereby preventing the measuring tape 4 from being damaged by mud, water stains, etc. adhered to the measuring tape 4 due to the complex environment of the construction site during use; Figure 3 and Figure 4 As shown, the hinge seat 12 is a conventional hinge seat, and the upper end of the scraper 9 is hinged thereto, wherein the width of the tape measure 4 is smaller than the width of the scraper 9 to ensure that the scraper 9 can scrape the tape measure 4, and the hard sponge 11 is a sponge with a relatively high density;

[0031] like Figure 3 and Figure 4 As shown, a baffle 19 is fixed on the hinge seat 12 for limiting the scraper 9 to swing forward only, so that when the measuring tape 4 is pulled outward, the scraper 9 is subjected to a forward force and then swings forward, and at this time, the scraper 9 presses the measuring tape 4 on the hard sponge 11 again, so as to avoid the worker having to work hard when pulling out the measuring tape 4 due to the friction between the scraper 9 and the measuring tape 4;

[0032] like Figure 3 and Figure 4 As shown, the front side wall of the scraper 9 is provided with a groove for facilitating the swinging of the scraper 9, and the scraper 9 can be actively tilted up before use through the groove.

[0033] When using this embodiment, first, one person holds the zero scale end of the measuring tape 4 and aligns it with the measurement starting point, and the other person holds the housing 16 and the mounting frame 1 and moves them to the measurement end point and reads the reading to complete the measurement. When the measuring tape 4 is pulled out for a short distance, the crank handle 3 is directly rotated manually to rewind the released part of the measuring tape 4 into the mounting frame 1. When the measuring tape 4 is pulled out for a long distance, the housing 16 is taken out, and the square block 17 is aligned with the square groove on the second mounting plate 18 and inserted, and then the motor 15 is started. At this time, under the drive of the motor 15, the pulled-out part of the measuring tape 4 will be automatically retracted into the mounting frame 1. At the same time, under the action of the scraper 9 and the hard sponge 11, the mud and the like adhering to the surface of the measuring tape 4 will be scraped off, and the water stains and the like will also be absorbed during the retraction process, thereby maintaining a relatively high degree of dryness and cleanliness.

[0034] Example 2

[0035] This embodiment further illustrates the technology. The square block 17 is completely located inside the insert block 14. Figure 1 As shown, the insert block 14 provides a certain degree of protection for the square block 17, thereby preventing the square block 17 from being impacted when the housing 16 is dropped or placed, thereby preventing the motor 15 from being damaged.

[0036] Example 3

[0037] This embodiment further illustrates the technology. A handle 2 is fixed on the top of the mounting frame 1. Figure 1 and Figure 2 As shown, it is convenient for the staff to carry the device more conveniently and labor-savingly;

[0038] A conical head 10 is fixed to the bottom of the mounting frame 1. Figure 1 and Figure 2 As shown, the conical head 10 can not only more accurately align the measurement end point, but also facilitate fixing the device on the ground and then automatically reeling the measuring tape 4 by using the drive assembly without holding the mounting frame 1 by hand.
