Plug-in type connects snap close

Technical field

The utility model relates to the linkage that is used for the skin protective screening, relates in particular to the plug-in type that is used for the skin protective screening and connects snap close.

Background technology

At present, when skin is carried out maintenance construction, outside the building enclose earlier and builds scaffold, scaffold is outside equipped with protective screening, and protective screening is used to prevent that the fragment that flies, the coating that splashes from pounding or splashing passer-by.

Generally speaking, being connected between being connected between protective screening and the protective screening, protective screening and scaffold or the wire rope mainly finished by quoit.Referring to Fig. 1, " 8 " font quoit 6 that surrounds with iron wire for example, an end of " 8 " font quoit 6 is enclosed within on the wire rope 5, and the other end after passing mesh 7 on the protective screening 4 links together adjacent two protective screenings 4.Adopt this connected mode to cause protective screening in the process of lifting, to produce bigger frictional force, hindered the lifting of protective screening, easily protective screening is caused damage, and the safety of quoit is lower.

The utility model content

The purpose of this utility model is to provide a kind of plug-in type to connect snap close, and this connection snap close can reduce the frictional force that protective screening produces in lifting process, and its mounting or dismounting are easy, safe.

The utility model is achieved in that

A kind of plug-in type connects snap close, comprise snap close main body, contiguous block and fixture block, the snap close main body is the U type, snap close main body top outside has groove, be provided with fixture block in the groove, the fixture block top links to each other with top, snap close main body top, and the fixture block lateral surface is higher than snap close main body top outside, snap close bottom part body and contiguous block top are affixed, and the contiguous block surface has through hole.

The quantity of described contiguous block is two, the top of first, second contiguous block is affixed with the snap close bottom part body respectively, and first contiguous block is arranged on the place ahead of second contiguous block, there is the gap between first contiguous block and second contiguous block, the right side of first contiguous block has the opening that communicates with first through hole, the left side of second contiguous block has the opening that communicates with second through hole, and corresponding before and after first, second lead to the hole site.

Described fixture block comprises connecting rod and upper and lower two parts, link to each other by connecting rod between fixture block the first half and the latter half, fixture block cross section the first half is triangular in shape, fixture block cross section the latter half is rectangle, and the triangle base is parallel with the rectangle top margin, and leg-of-mutton base length is less than rectangular length.

The rectangular triangle of described fixture block cross section the first half, the rectangular outside of the latter half, fixture block cross section minor face is circular-arc.

Described connection snap close adopts engineering plastics to make.

The top of snap close main body is provided with fixture block in the utility model, and fixture block can move in groove under the effect of external force, thereby the top of the utility model connection snap close can be inserted in the mesh of adjacent protective screening easily, and adjacent protective screening is linked together.The bottom of snap close main body is fixed with two contiguous blocks, has corresponding through hole and opening on two contiguous blocks.When using this connection snap close, only need the connection snap close is vertically placed, make wire rope between two contiguous blocks, snap close is rotatably connected, wire rope is placed in the through hole of contiguous block by the opening on the contiguous block, be about to connect snap close and be enclosed within on the wire rope, be enclosed within on the wire rope thereby can under the prerequisite of not destroying this connection snap close, should connect snap close.The utility model can reduce the frictional force that protective screening produces in lifting process, its mounting or dismounting are easy, safe.

Among the figure: 1 snap close main body, 2 contiguous blocks, 21 first contiguous blocks, 22 second contiguous blocks, 3 fixture blocks, 31 connecting rods, 4 protective screenings, 5 wire rope, 6 quoits.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 2, a kind of plug-in type connects snap close, comprises snap close main body 1, contiguous block 2 and fixture block 3.Snap close main body 1 is the U type, and snap close main body 1 top outside has groove, is provided with fixture block 3 in the groove, and fixture block 3 tops link to each other with top, snap close main body 1 top, and referring to Fig. 3, and fixture block 3 lateral surfaces are higher than snap close main body 1 top outside.

Referring to Fig. 4, fixture block 3 comprises connecting rod 31 and upper and lower two parts, link to each other by connecting rod 31 between fixture block 3 the first half and the latter half, the rectangular triangle of fixture block 3 cross section the first half, fixture block 3 cross section the latter halfs are rectangle, and the triangle base is parallel with the rectangle top margin, and leg-of-mutton base length is less than rectangular length.In the present embodiment, the rectangular outside of fixture block 3 cross section the latter halfs minor face is circular-arc, makes fixture block 3 feel in the process that presses down better.

Snap close main body 1 bottom and first, second

contiguous block

21,22 tops are affixed, and first contiguous block 21 is arranged on the place ahead of second contiguous block 22, have the gap between first contiguous block 21 and second contiguous block 22, referring to Fig. 3.Have first through hole and second through hole at first contiguous block 21 and second contiguous block, 22 surfaces, corresponding before and after first, second lead to the hole site, and the right side of first contiguous block 21 has the opening that communicates with first through hole, and the left side of second contiguous block 22 has the opening that communicates with second through hole.

The utility model connects snap close and adopts engineering plastics to make, and has certain elasticity.

When using this connection snap close, will connect snap close earlier and vertically place, and make first contiguous block 21 be positioned at the left side of second contiguous block 22, wire rope 5 is between first, second contiguous block 21,22.To connect snap close half-twist in a clockwise direction again, wire rope 5 is placed in first, second through hole, and be about to connect snap close and be enclosed within on the wire rope 5.Press down the latter half of snap close main body 1 top fixture block 3, adopt engineering plastics to make owing to connect snap close, has elasticity, and fixture block 3 tops link to each other with snap close main body 1 top, therefore fixture block 3 the latter halfs are under the effect of external force, with fixture block 3 tops is the axle center, moves in groove, is in same plane until the hypotenuse and snap close main body 1 top outside of fixture block 3 cross section the first half right-angled triangles.Then, the top of snap close main body 1 is inserted respectively in the mesh 7 of adjacent two protective screenings 4, decontrol the latter half of fixture block 3, the mesh 7 that makes protective screening 4 is between fixture block 3 the first half and the latter half, promptly finished the connection of adjacent two protective screenings 4, referring to Fig. 5.

In the time the connection snap close will being removed, only need press down the first half or the latter half of fixture block 3, make fixture block 3 withdraw from mesh 7, the snap close that is rotatably connected again makes wire rope 4 withdraw from first, second through hole and gets final product.

The utility model can reduce the frictional force that protective screening produces in lifting process, its mounting or dismounting are easy, safe.
