Abstract

The utility model relates to a fast assembling and disassembling pipe clamp which is composed of a pipe clamp seat, a pipe clamp cover, a pin shaft, a T-shaped rod, an angle-shaped clamp seat and a locking cap. One end of the pipe clamp cover and the pipe clamp seat are hinged on the pin shaft, a T-shaped head of the T-shaped rod is installed in a concave arc trough of the pipe clamp seat, and the concave arc trough is provided with a hole. A trough is arranged on the pipe clamp seat, the angle-shaped clamp seat is provided with a square hole and a clamp angle, the angle-shaped clamp seat is sheathed at the outside of the T-shaped rod, and the clamp angle is downward. The top surface of the angle-shaped clamp seat is provided with a flange, the locking cap is provided with a circular hole, the locking cap is sheathed at the outside of the T-shaped rod, and the bottom surface of the locking cap is provided with the flange. The utility model has the advantage of rapid screwing speed; compared with the prior art, the screwing speed of the utility model is improved by 30 times or so.

Description

Fast loading and unloading pipe clamp

The utility model relates to a kind of fast loading and unloading pipe clamp, mainly sets up usefulness with the two tubes in length and breadth of fastening scaffold for building operations.

Existing scaffold pipe clamp is seen Fig. 7, is made of pipe clamp seat 2, pipe loam cake 1, bearing pin 3, T font bolt 23 and nut, be put in length and breadth pipe clamp on the pipe after, fastening nut is tightened to scaffold with pipe in length and breadth.Its weak point is: for adapting to the needs of different tube diameters, give and stay reach longer, the number of threads of tightening is more, must expend the long time when installing at every turn, and general the fastening of every pair of pipe clamp needs 2-3 minute approximately.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of fast-assembling pipe clamp is provided.

The purpose of this utility model can reach by following measure: the utility model is made of pipe clamp seat, pipe clamp lid, bearing pin, T shape bar, dihedral deck and locking cap, pipe clamp covers an end and the pipe clamp seat is articulated on the bearing pin, the T shape head of T shape bar is packed in the pipe clamp seat concave arc groove with holes, pipe clamp has covered groove, the dihedral deck has square hole and Ka Jiao, the dihedral deck is set in the outer and Ka Jiao of T shape bar down, dihedral deck end face has flange, locking cap has circular hole, locking cap is set in outside the T shape bar, and there is flange the locking cap bottom surface.

T shape bar bottom is square, and top is circular, and baffle plate is arranged at the top.

The drawing of accompanying drawing is described as follows:

Fig. 1 is total figure of the present utility model, the state that the expression pipe clamp is tightened;

Fig. 2 be the A of Fig. 1 to view, the state that the expression pipe clamp is not tightened as yet;

Fig. 3 be the B of Fig. 1 to view, express the ground plan of locking cap;

Fig. 4 is the profile of Fig. 3 circular arc 20, and starting point is 21 points of Fig. 3;

Fig. 5 be the C of Fig. 1 to view, express the top plane view of dihedral deck;

Fig. 6 is the local figure of the section of Fig. 5 circular arc 20, and starting point is 22 points of Fig. 5;

Fig. 7 is total figure of prior art.

The accompanying drawing piece number is represented:

1, pipe clamp lid 2, pipe clamp seat 3, bearing pin 4, angle-shaped groove 5, dihedral deck

6, card angle 7, T shape bar 8, T shape 9, concave arc groove 10, square bar

11, round bar 12, card angle 13, square hole 14, circular hole 15, locking cap

16, flange 17, baffle plate 18, standpipe 19, transverse tube 20, circular arc

21, starting point 22, an indication 23, T font bolt

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 and Fig. 6 represent general structure of the present utility model.Pipe clamp covers 1 one ends and pipe clamp seat 2 is articulated on the bearing pin 3, and the end in addition of pipe clamp lid has angle-shaped groove 4, for the card angle 6 of dihedral deck 5 crouch into and the pipe clamp lid carried out fastening usefulness.The T shape of T shape bar 78 is packed in the pipe clamp seat concave arc groove 9 with holes, and T shape shaft bottom is a square bar 10, and top is round bar 11.Dihedral deck 5 lower ends have card angle 12 and central authorities that square hole 13 is arranged, and the square hole of dihedral deck is set in the square bar of T shape bar, to guarantee the unlikely rotation of dihedral deck, like this, Ka Jiao just can snap in the angle-shaped groove securely, can slippage under the vibration situation during use yet, and reliable to guarantee construction safety.There is the locking cap 15 of band circular hole 14 dihedral deck top.The end face of dihedral deck and the bottom surface of locking cap all have the flange 16 of identical shaped and size (to see Fig. 3-Fig. 6) for details.Solid welding has baffle plate 17 on the T shape masthead.

During use, earlier a pipe clamp is placed on the pipe (as standpipe 18) of scaffold and sees Fig. 1, angle-shaped groove 4 is put at the card angle 12 of dihedral deck, sub locking cap is rotated maximum 90 ° with removing again, just can lock see shown in Figure 1.During dismounting,, can unclamp and dismantle maximum 90 ° of locking cap counter-rotation.

The utility model contrast prior art has the advantage of tightening quick (fast about 30 times).
