DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0032] As Figures 1 to 5 shown, a construction engineering measuring device, including the shell 1, the inside cavity of the shell 1 one side surface is provided with pull ring 101 to facilitate the portable device, and the extension groove 2 is arranged at the bottom end surface of one side of the shell 1 to make the tape measure 4 extend from its inside, the scraping piece 3 arranged at the extension groove 2 one side surface can clean the dust on the surface of the tape measure 4, and the right angle piece 401 is arranged at one end of the tape measure 4, so that it can be conveniently hung at one end of the measurement, the drive assembly 5 located inside the shell 1 is provided with knob 501, which drives the winding piece 502 on one side surface to wind the tape measure 4 under the limiting of the ratchet 503, the card piece 6 located at one side of the ratchet 503 limits the ratchet 503, and the fixed shaft 601 is arranged inside the card piece 6 and connected with the torsional spring 602, so that the card piece 6 can be clamped on the surface of the ratchet 503, the limiting assembly 7 installed on one side of the card piece 6 is provided with rotating rod 701, which is connected with baffle 703 through moving rod 702 on one end surface of rotating rod 701, so that the card piece 6 can be separated from the ratchet 503 under the pulling of pull rod 705 outside the baffle 703.

[0033] The scraping piece 3 attached to the surface of the tape measure 4 is provided with slope structure on both sides.

[0034] Through the above technical scheme, the slope structure is arranged, so that when the tape measure 4 is stored in the inside of the shell 1, the dust can be scraped off to the surface of the scraping piece 3 through the slope structure, which is more convenient for subsequent cleaning.

[0035] The knob 501 rotatably connected to the surface of the shell 1 controls the ratchet 503 to rotate on one side surface inside the shell 1 through the rotating ring 504.

[0036] Through the above technical scheme, under the limiting of the rotating ring 504, the ratchet wheel 503 can rotate more stably in the process of rotation, thereby driving the winding member 502 to wind the measuring tape 4.

[0037] The torsion spring 602 is fixed to one end of the clamping member 6 inside and connected with the fixed shaft 601 inside the shell 1. The fixed rod 604 is fixed by the groove 603 on the surface of the clamping member 6, and the rotating rod 701 rotates on the surface thereof.

[0038] Through the above technical scheme, under the limiting of the fixed rod 604, the clamping member 6 can be separated from the clamping of the ratchet wheel 503 by rotating when the limiting assembly 7 pulls outward.

[0039] The moving rod 702 and the baffle 703 slide and rotate in the cavity inside the pull rod 705. The spring 704 sleeved on the surface of the moving rod 702 is attached to the baffle 703 and the inside of the pull rod 705, and the fixed groove 706 fixed on the surface of the shell 1 is arranged outside the pull rod 705.

[0040] Through the above technical scheme, under the arrangement of the fixed groove 706, the pull rod 705 can be limited, so that it can slide inside the fixed groove 706. Thus, under the assistance of the spring 704, the pull rod 705 can be pulled to move the rotating rod 701 through the baffle 703.

[0041] The clamping block 751 is arranged on the surface of the pull rod 705 and slidably connected inside the limiting ring 761 arranged in the fixed groove 706. The clamping groove 762 and the through hole 763 are arranged on one side inside the limiting ring 761, so that the size of the clamping block 751 is consistent with the two.

[0042] Through the above technical scheme, under the clamping of the clamping block 751, the pull rod 705 can be limited by the clamping block 751, so that it can be placed inside the clamping groove 762. In the case that the pull rod 705 does not rotate, it cannot pull the clamping member 6 to separate from the ratchet wheel 503.

[0043] In use, when the user uses the construction engineering measuring device, one side of the tape 4 is pulled, the tape 4 can be pulled out of the shell 1 through the rotation of the winding piece 502, and through the mutual clamping of the ratchet 503 and the clamping piece 6, the reverse rotation of the ratchet 503 is avoided, thereby limiting the position of the tape 4, facilitating the measurement by the tape 4, in the process of pulling out the tape 4 outwardly, when the ratchet 503 rotates counterclockwise, the clamping piece 6 can rotate on the surface of the fixed shaft 601 under the torsion of the torsional spring 602, thereby limiting the ratchet 503 through the upper end of the clamping piece 6, and the rotating rod 701 rotates on the surface of the fixed rod 604, pushes the moving rod 702 and the baffle 703 to slide in the pull rod 705 under the elastic force of the spring 704, thereby ensuring that the clamping piece 6 can more stably clamp the ratchet 503, and when the measurement work is completed, the tape 4 needs to be retracted into the shell 1, first press the pull rod 705 inwardly, so that the clamping block 751 is separated from the clamping groove 762, then rotate the pull rod 705, so that the clamping block 751 on the surface of the pull rod 705 can rotate in the limiting ring 761, when rotating to the through hole 763, pull the pull rod 705 outwardly, so that one end inside the pull rod 705 can press the spring 704, thereby driving the baffle 703 to move outwardly, so that the rotating rod 701 rotates on the surface of the fixed rod 604, pulls out the clamping piece 6, and separates the clamping piece 6 from the clamping of the ratchet 503, so that the knob 501 can drive the winding piece 502 to rotate, and the tape 4 is wound.
