Description

A kind of Construction Quality Accreditation Tool

Technical field

The utility model belongs to technical field of building construction, and more specifically, more particularly to a kind of Construction Quality is tested It puts the tools away.

Background technology

The magnetic line of force is fallen：The principle that vertical line is formed using vertical dead weight bracing wire measures a kind of instrument of verticality, is building Construction quality often uses one of Accreditation Tool.

Based on above-mentioned, the inventors discovered that, the magnetic line of force falls itself, and there are some potential safety problemss：The fixation steel of magnetic line of force pendant The needle portion of needle is very sharp, and the operator (especially children) of performance is fallen for not knowing about the magnetic line of force, accidentally presses solid When determining the shank of draw point, and finger or hand are placed on pin hole position, it is easy to the needle portion opponent for the fixation draw point being pressed out Refer to or hand causes to stab, there are larger security risks, but existing magnetic line of force pendant is not arranged accordingly at pin hole position Protective device.

Then, in view of this, being studied improvement for existing structure and missing, a kind of Construction Quality is provided and is tested It puts the tools away, to achieve the purpose that with more more practical value.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of Construction Quality Accreditation Tool, existing to solve Corresponding protective device is not arranged in some magnetic line of force pendants at pin hole position, and there are larger security hidden troubles.

The purpose and effect of the utility model Construction Quality Accreditation Tool, are reached by technological means in detail below：

A kind of Construction Quality Accreditation Tool, including magnetic line of force pendant main body, fixed draw point, the first threaded hole, steel pinhole, It is shaft protrusion, the second threaded hole, U-shaped recess slot structure, provision for disengagement, round buckle closure, the first stud, trapezoidal block-shaped protrusion, different Shape protruding block, protection disk, rubber spacer, the first counterbore, the second counterbore, fixing device, round block, the second stud and abnormity are recessed Slot；The magnetic line of force pendant bottom part body goes out to offer the U-shaped recess slot structure at one corresponding to the steel pinhole position；It is described U-shaped recess slot structure female ends face is located at the steel pinhole directly to the right orientation place of setting and is provided with one piece of shaft protrusion, and U-shaped Recess slot structure female ends face is located at the steel pinhole directly to the left orientation place of setting and offers second threaded hole at one；One piece of institute It states and second counterbore at first counterbore and one is offered at one with its axle center circular array shape respectively on protection disk； The protection disk is rotatedly connected with the shaft protrusion by first counterbore and is connect, and described second protected in disk is sunk Hole is in same axle center with second threaded hole；When second counterbore and second threaded hole are in concentric state Under, one passes through the second counterbore spiral shell by the fixing device that the round block, the second stud and special impression collectively constitute Line is connected in second threaded hole；Second stud, and circle are welded at the round block bottom face shaft core position The special impression at one is offered at block top end face shaft core position；Second stud is connected across second counterbore threads When in second threaded hole, the bottom face of the round block fits with the second counterbore indent end face, and the top of round block End face is same as same level with the protection disk top end face；The needle of the fixed draw point of the magnetic line of force pendant body top First threaded hole at one is offered at handle head hub position；The needle handle top of the fixed draw point is threaded with one group The provision for disengagement collectively constituted by the round buckle closure, the first stud, trapezoidal block-shaped protrusion and special-shaped protruding block；The circle Shape buckle closure indent end face shaft core position is fixedly connected with first stud, and round buckle closure outer profile end face battle array in a ring Column-shaped is provided with ten pieces of trapezoidal block-shaped protrusions；It is fixedly connected with one piece and institute at the first stud bottom face shaft core position State the matched special-shaped protruding block of special impression.

Further, the thickness of the protection disk is consistent with the U-shaped recess depth of slot structure.

Further, the protection disk bottom face shaft core position is embedded with one piece of rubber spacer, when the protection When second counterbore in disk is in same axle center with second threaded hole, at the protection disk and the steel pinhole In same axle center.

Further, the needle of the depth and the fixed draw point in the round buckle closure concave end face in the provision for disengagement Handle tip thickness is consistent, and the needle handle top outer diameter phase one of the internal diameter and the fixed draw point in the round buckle closure concave end face It causes.

Further, the protection disk is rotatable regulating device, and its rotation adjusts angle ranging from 0-360 degree.

Compared with prior art, the utility model has the advantages that：

By protecting the setting of disk, it is conducive to when without using the utility model, can be protected by being rotated along shaft protrusion Disk so that protection disk shelters from steel pinhole, and disk will be protected to fix by fixing device, is conducive to by protecting disk Block, protection does not know about the operator of magnetic line of force pendant performance, will not be because of the fixed draw point shank of pressing, and is fixed steel Needle needle portion is stabbed, and further, protection disk bottom face shaft core position is embedded with one piece of rubber spacer, is conducive to hide in protection disk When keeping off steel pinhole, if the operator for not knowing about magnetic line of force pendant performance makes fixed draw point needle in the fixed draw point shank of pressing When subordinate presses, fixed draw point needle portion can be pierced into rubber spacer, will not be in contact with protection disk, to avoid causing fixed steel The fracture damage in needle needle portion.

When second stud is connected to across the second counterbore threads in the second threaded hole, in the bottom face of round block and the second counterbore Female end face fits, and the top end face of round block with protection disk top end face be same as same level so that not by with abnormity Under the special-shaped protruding block twisting disassembling section of fit depressions, it is difficult to fixing device is taken apart out of second threaded hole, with Ensure when children touch the utility model, protection disk can not be moved at all and expose its steel pinhole blocked, to protect children Draw point needle portion will not be fixed to damage.

The depth in the round buckle closure concave end face in provision for disengagement is consistent with the needle handle tip thickness of fixed draw point, And the internal diameter in round buckle closure concave end face is consistent with the fixed needle handle top outer diameter of draw point so that under normal viewing angle viewing, Because can't see the connection profile between provision for disengagement and the needle handle top of fixed draw point, therefore one is considered, to play fascination Effect prevents children from finding provision for disengagement and dismantles fixing device by it.
