Abstract

The utility model relates to an improved structure of a joint which is used for a work bench. The utility model comprises a straight rod which is provided with a plurality of buckle seats and a connecting rod which is provided with plugs respectively at both ends. The buckle seats are provided with a plurality of buckle holes. Movable buckle pieces are pivoted and connected at the bottom parts of the plugs. When the plugs are combined with the buckle holes of the buckle seat, the upper ends of the buckle pieces can withstand the bottom parts of the buckle seats to prevent the looseness of the plugs, so a safe work bench with simple and rapid assembly is provided.

Description

The falsework improvement structure of joint

Technical field

The utility model relates to the improvement structure of falsework with joint, is for the usefulness that combines of the straight-bar that constitutes falsework such as scaffold etc. with connecting rod.

Background technology

Existing falsework joint, as No. 92201818 " quick coupling structure of frame " patent case of TaiWan, China, be that solid welding has joint fastener on vertical mast, described joint fastener is provided with first and second button hole, and the transverse tube joint is provided with engagement groove, and described engagement groove is provided with upper and lower jack, rely on described joint fastener to insert the engagement groove of transverse tube joint, make the upper and lower jack and the first button hole overlaid of engagement groove, insert latch and interlock admittedly, will indulge mast and combine with the transverse tube joint; The latch of second button hole and inclined tube joint interlocks solid, will indulge mast and combine with the inclined tube joint; Because described vertical mast all is to interlock admittedly with latch with combining of transverse tube joint or inclined tube joint, described latch very easily comes off because of careless collision, vertical mast is combined, therefore with the transverse tube joint or with the inclined tube joint not, security incident takes place easily, so undesirable.

Summary of the invention

Main purpose of the present utility model be provide at aforementioned disappearance a kind of can be simple and easy and the improvement structure of the good falsework usefulness joint of assembling and safety fast.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of falsework is made of a straight-bar and a connecting rod with the improvement structure of joint, and it is characterized in that: described straight-bar is provided with more than one Button Block, and a predetermined distance is arranged between adjacent two Button Blocks, and Button Block is provided with several button holes; Described connecting rod two ends are respectively equipped with a plug, plug has different with the angle of connecting rod according to need, the plug bottom is provided with a slotted eye, be articulated with a cramp with a pin member in the slotted eye, the plug of connecting rod combines with the button hole of the Button Block of its corresponding straight-bar, expose outside slotted eye described cramp upper end, and two described cramp upper ends prop up the Button Block bottom and prevent that plug from getting loose.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: when plug combines with the button hole of Button Block, described cramp upper end can prop up the Button Block bottom and prevent that plug from getting loose and a kind of simple and easy, assembling and safe falsework fast are provided.

Description of reference numerals: 1-straight-bar; The 11-Button Block; The 111-button hole; The 2-connecting rod; The 21-plug; The 211-slotted eye; The 212-cramp; The 213-pin member.

The specific embodiment

As shown in Figure 1, the utility model mainly provides the improvement structure of a falsework with joint, is made of a straight-bar 1 and a connecting rod 2, and wherein: described straight-bar 1 is provided with more than one

Button Block

11,11 of adjacent two Button Blocks have a predetermined distance, and Button Block 11 is provided with several button holes 111.

Described connecting rod 2 two ends are respectively equipped with a plug 21, plug 21 has different with the angle of connecting rod 2 according to need, for example: when the angle of the plug 21 at two ends and connecting rod 2 is 90 when spending, described connecting rod 2 can use for making cross bar, again for example: when the angle of the plug 21 of an end and connecting rod 2 is that the angle of plug 21 and the connecting rod 2 of 45 degree, the other end is 135 when spending, described connecting rod 2 can be for doing the brace use; Plug 21 bottoms are provided with a slotted eye 211, are articulated with a cramp 212 with a pin member 213 in the slotted eye 211, and making cramp 212 can be axle and activity with pin member 213.

Please cooperate shown in Figure 2 again, when the plug 21 of connecting rod 2 combines with the button hole 111 of the Button Block 11 of its corresponding straight-bar 1, described cramp 212 exposes outside the slotted eye 211 because of action of gravity makes cramp 212 upper ends, and described cramp 212 upper ends can prop up Button Block 11 bottoms and prevent that plug 21 from getting loose.

Please cooperate again shown in Figure 3, when cramp 212 upper ends are pushed back in the slotted eye 211, the plug 21 of connecting rod 2 can by on carry and get loose with the button hole 111 of the Button Block 11 of straight-bar 1.

By above-mentioned structure, when can understand the utility model can be simple and easy with fast plug is combined with the button hole of Button Block, and prevent that plug 21 from getting loose the falsework of a safety be provided owing to described cramp 212 upper ends can prop up Button Block 11 bottoms.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.

Claims
