Abstract

The utility model relates to a drawout clamp, and aims to provide a drawout clamp, which is simple in structure, convenient in manufacture and low in manufacturing cost. The drawout clamp can be adjusted for a plurality of times in mounting and fixing, and is reliable in mounting and fixing. According to the technical scheme, the drawout clamp is characterized by comprising a rebar clam and a draw strip. One end of the draw strip in a strip shape is a draw end, and the other end of the draw strip is a free end, while the ends of the draw strip are bent to form hooks. The rebar clamp in a U shape is made of a bent steel plate. Clamping slots corresponding to the draw strip in width and thickness are reserved on two sides of the rebar clamp by punching. The clamping slot on one side of the rebar clamp is sleeved below the draw end of the draw strip, and an open end of the rebar clamp faces down.

Description

The drawing and pulling type geometrical clamp

Technical field

The utility model relates to a kind of geometrical clamp, especially a kind of drawing and pulling type geometrical clamp.

Background technology

For example typically use the iron wire colligation or the U-shaped steel bar framework is fixed at the fitting operation of sound detecting pipe; Because when transferring reinforcing cage; Sound detecting pipe needs secondary to connect, and sound detecting pipe need move and adjust in the connection procedure, so sound detecting pipe can not be fixed motionless before transferring reinforcing cage.Traditional sound detecting pipe needs twice colligation operation when transferring reinforcing cage in the place; Waste time and energy; Waste to material is also bigger, and operation is more, and the probability of makeing mistakes when the workman operates has also increased; Therefore develop a kind of easy to operately, and adjustable geometrical clamp just is necessary very much can install and fix the time.

Summary of the invention

The technical problem that the utility model will solve is: to the problem of above-mentioned existence, a kind of simple in structure, easy to make and drawing and pulling type geometrical clamp that cost of manufacture is low is provided, can when installing and fixing, repeatedly adjusts, install and fix reliable.

The technical scheme that the utility model adopted is: a kind of drawing and pulling type geometrical clamp is characterized in that: said geometrical clamp comprises bar clamp and pull bar, and the pull bar is ribbon, the one of which end is the pull end, and the other end is free end and is bent into grab in the end; Said bar clamp is that steel plate is bent into the U type, and the both sides of bar clamp dash has the draw-in groove corresponding to pull bar width and thickness; Side bayonet slot on the bar clamp is inserted in the below of pull bar pull end and makes the bar clamp openend downward.

Said pull end curves annulus and is fixed by rivet.

The outer side blow of said grab has the outside anticreep shell fragment of opening.

Towards flexible lock banking stop, shell fragment is towards the inboard on the said pull bar.

Towards flexible anti-slide plate, shell fragment is towards the inboard on the said bar clamp.

The material of said bar clamp and pull bar is a spring steel.

The beneficial effect of the utility model is: simple, the easy to make and low preparation cost of this drawing and pulling type geometrical clamp framework; Fastening devices commonly used has more convenient to operate; And can when installing and fixing, can adjust, it is firm to install and fix, and has very high promotional value.

The specific embodiment

Drawing and pulling type geometrical clamp as shown in Figure 1, as can to adjust when present embodiment is a kind of installing and fixing, this geometrical clamp is made up of bar clamp 2 and pull bar 3.

Said bar clamp 2 is for to be bent into U-shaped by steel spring plate, and its both side surface is dashed respectively has the draw-in groove 2-1 corresponding to pull bar 3 width and thickness, forms the duct that pull bar 3 passes through; Also towards flexible anti-slide plate 2-2, shell fragment is towards inboard (see figure 2) on the bar clamp 2.Said pull bar 3 processes for banded spring steel; One end of pull bar 3 is the pull end 3-4 (end is fixed with rivet 1 after curving ring-type) of annular; The other end is free end and is bent into grab 3-1 in the end that the outer side blow of this grab has the outside anticreep shell fragment 3-2 of opening; There are being plurality of elastic lock banking stop 3-3 (see figure 3), this elasticity lock banking stop can cooperate draw-in groove 2-1 to realize pull bar 3 lockings near pull end place along pull bar 3 even dashing.

Before processing pull end 3-4, must earlier pull bar 3 be passed bar clamp 2 one side bayonet slot 2-1, the shell fragment of elasticity lock banking stop 3-3 inwardly, bar clamp 2 openends are downward, then this pull end curved annulus and fixed by rivet 1.It is subsequent use so to connect the back.

Bar clamp 2 and pull bar 3 all adopt the processes of panel beating stamping-out, bending, and production technology is simple, and be efficient, and dimensional accuracy is high.After the finished product heat treatment, external surface adopts blackout to handle, and can play rust inhibition.

The method for using of drawing and pulling type geometrical clamp in the sound detecting pipe fitting operation: the bar clamp 2 with the drawing and pulling type geometrical clamp during use is clamped on the assigned address on the reinforcing cage master muscle; With hand pull bar 3 is bent; Another draw-in groove 2-1 that the grab 3-1 of one end is hooked in bar clamp 2 upward and through anticreep shell fragment 3-2 makes grab be locked in current location, oval-shaped sound detecting pipe placement space of pull bar 3 formation this moment.Repeat this operation, this geometrical clamp of on the main muscle of reinforcing cage, all having arranged; Subsequently with sound detecting pipe from reinforcing cage one end, one arrange in the geometrical clamp along what main muscle direction penetrated that a step places; At last the sound detecting pipe pipe end is hooked, come off in the handling process preventing.

When transferring reinforcing cage, with the pull end 3-4 tension of hand, sound detecting pipe is close on the reinforcing cage master muscle with pull bar 3, promptly accomplish the colligation of sound detecting pipe.Slowly transfer reinforcing cage, the tension while transferring is all tightened up until the pull bar of all drawing and pulling type geometrical clamps.
