Abstract

The utility model relates to a quick coupler used for the lap joint of bars, comprising a pipe clamping seat with two U-shaped openings with different surfaces, and a gland matched with the pipe clamping seat. The gland has two layers of parallel pin seats, wherein, one layer at one end is an oblong step hole, and the other layer is an eccentric oblong hole which is partially widened. One end of the pipe clamping seat is provided with a pin seat with an eccentric oblong hole partially widened, and a cuniform pin whose thin end is provided with a pair of lug bosses is driven in the pin seat. The utility model has convenient installation, easy disassembly, good self-locking performance, and convenient portability.

Description

Quick coupler

The utility model belongs to the rod member lap device, relates to a kind of fast connecting fastener that is mainly used in scaffold rod member overlap joint.At present in the building operations during scaffolding, also continue to use the mode of bolton mostly.This bolt fastener often causes damaged member because the dismounting of getting rusty is difficult, and it is extremely inconvenient to carry bolt and nut when mounted simultaneously, and bolt and nut falls down and also can hurt sb.'s feelings, and causes unsafe factor.

The purpose of this utility model is to provide a kind of fast connecting fastener, overcomes the prior art deficiency, and installing/dismounting is easy, easy to carry, and self-locking property is good, and is safe in utilization.

The utility model is achieved through the following technical solutions: a kind of fast connecting fastener that is used for the rod member overlap joint comprises pipe clamp seat with 2 antarafacial U-shaped openings and the gland that matches with this.The U-shaped open end of pipe clamp seat respectively has 1 key seat that stretches out, and wherein has circular pin hole on 1 key seat, has the eccentric slotted hole that the part is widened on 1 key seat in addition.The two ends of gland are provided with double-deck parallel key seat, and the key seat that the spacing of parallel key seat can be held on the pipe clamp seat easily inserts.All have circular pin hole on the double-deck key seat of one end, have oval stepped hole on the double-deck key seat last layer of the other end, have the eccentric slotted hole that the part identical with the pipe clamp seat widened on another layer towards the inboard.2 glands borrow key seat that circular pin hole is arranged on the circular pin hole one end grip tube deck and pin joint respectively on the pipe clamp seat.On the oval stepped hole of gland the plane wedge pin is housed, the butt end of wedge pin can all not pass oval stepped hole in the outside, on the thin transverse plane a pair of relative boss is arranged, the size of described boss just assurance wedge pin can not come off from slotted hole and can pass through from the slotted hole that the part is widened.

Only need when the utility model uses pipe fitting is pressed on the pipe clamp seat with gland, with wedge pin is urgent can be tightly with the pipe fitting fixing.The meeting tensioner was at oval stepped hole and local narrow section of widening eccentric slotted hole after wedge pin was squeezed into, and self-locking property is good., very convenient during dismounting as long as from oppositely getting wedge pin.Wedge pin is borrowed boss to be retained on can not come off in the slotted hole and is hurted sb.'s feelings.Pin is connected as a single entity easy to carry with fastener.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying

drawing

1,3,4,5,8,9,10 has showed that the utility model is used for an embodiment of the fast fitting of quadrature.In actual applications, quadrature connects soon and occupies bigger proportion.2 antarafacial U-shaped openings of pipe clamp seat (3) mutually at an angle of 90.Pipe clamp seat (3) gland (2) and wedge pin (1) are all by GB976-67, and foundry goods is not less than malleable cast iron and makes.

Accompanying drawing 2,4,5,6,7,8,9,10 has showed that the utility model is used for the embodiment of corner fast connecting fastener.Pipe clamp seat (3) is made up of two parts.Two parts pipe clamp seat (3) all has the U-shaped opening, and its U-shaped bottom outside is the plane, and there is centre bore (9) at the center, with rivet (4) two parts pipe clamp seat (3) is riveted together, and two parts pipe clamp seat (3) can be rotated each other.

Embodiment one is mainly used in the situation that two pipe fittings intersect vertically, and second embodiment can be used for two pipe fittings and intersect connection at any angle.

Claims
