Description

Folding toggle connector

The utility model relates to a kind of collapsible connection set, and is particularly a kind of for the collapsible toggle connection set that uses in composite furniture and the pivot joint of support group bridge.

In the bridge structure of composite furniture and support group, in order to consider that some position can folding or expansion, the general structure of amounting to the support group that all is provided with, its basic structure as depicted in figs. 1 and 2, it has two by the plate body or the body of rod 14, one L shaped buttcover plate 13 abuts in a side of two plate bodys 14 and is hubbed on buttcover plate 13 1 sides by 12 liang of plate bodys of bearing pin, is provided with the fixing part 11 of mutually concavo-convex inlay card in the contact inboard of fitting of buttcover plate 13 and plate body 14.When left plate body and the nonrotational active side of right panel body are stressed, plate body 14 be subjected to L shaped buttcover plate 13 cards along 131 block and can not folding, be subjected to big slightly active force but can not support.Because all holding from width or intensity along 131, card can't stand a little active forces.As rotating the active side application of force at it, but then plate body folding.The effect of fixing part 11 is slightly with plate body and connecting plate location and don't influence its folding.But this kind structure vibrated or touch after very easy taking off close the location, cause unstable easily and unsafe factor.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of exhibition of rolling over is convenient, the location is reliable, prop up the good a kind of collapsible toggle connection set of intensity and provide.

The purpose of this utility model is to realize by following technological scheme:

The two U-shaped bodies of rod connect together by its pivot activity pivot of piecing together locating top, piece together the opposite end internal fixation at the two U-shaped bodies of rod fixed block is arranged, on each fixed block, respectively be pivoted with a fixture block, be provided with spring between the cover plate of the top of fixture block and its top, the spring strong point and pivot do not have between the pivot of fixture block a deviation distance are arranged, there is a sliding bolt at place, diapire space at the fixed block bottom and the U-shaped body of rod, on the sliding bolt two interval draw-in groove can fasten with fixture block and locate or disengaging, so that the two U-shaped bodies of rod can prop up into direct rod shape or folding.

Therefore: remarkable result of the present utility model is:

The 1st: because sliding bolt and can float the setting of the fixture block of support engaging had automatically both guaranteed stability and the reliability of the two U-shaped bodies of rod when propping up, again can be when the needs folding be pieced together with the sliding bolt extraction and make two bodies of rod carry out folding.

The 2:U shape body of rod and horizontal in its positioning action to the sliding bolt of assembly place inboard makes its support intensity, and the external force resistance ability all is greatly improved.

The 3rd: because of pivoting point is arranged on uncovered evagination place on the two U-shaped body of rod inboards, thereby, do not interfere, so can to 180 degree scopes, carry out folding or expansion at 0 degree with U-shaped body of rod inside.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof:

Be described in detail below in conjunction with 3 to 8 pairs of concrete structures of the present utility model of accompanying drawing:

The utility model has two plate bodys that are articulated 14, it is characterized in that: two U-shaped plate bodys 14 connect together by the pivot 16 mutual pivots of uncovered inboard on the U-shaped plate body, respectively be connected with a fixed block 18 at two U-shaped plate bodys 14 to piecing together end inside, respectively be pivoted with a fixture block 20 on two fixed blocks 18, support has spring 19 between the top of fixture block 20 and the pressing plate above it 17, horizontal activity in two fixed blocks, 18 bottoms to the chamber 15 between U-shaped plate body 14 inside bottom wall has inserted sliding bolt 22, and the two interval draw-in grooves 222 on sliding bolt 22 tops fasten with the lower end of the fixture block 20 that is positioned at its top.Referring to Fig. 2 to Fig. 5

Structure characteristic of the present utility model also is:

Pivot 16 be fixed on one of two U-shaped plate bodys 14 the inboard, end width direction and be articulated with pivot connecting plate 23 activities of another inboard, U-shaped plate body 14 end, pressing plate 17 be separately fixed between two U-shaped plate bodys 14 last uncovered laterally, fixture block 20 is articulated in fixed block 18 inboards of pressing plate 17 bottoms separately for the cutting knife shape of triangular shape and by bearing pin 21, sliding bolt 22 for lath-shaped and laterally activity be plugged between the assembly rank place of two U-shaped plate bodys, 14 inside bottom wall laterally, in the U-shaped plate body 14 of the side of moving pull end of sliding bolt 22, a positive stop 24 is arranged.Referring to Fig. 3 to Fig. 5

Sliding bolt 22 move the pull handle 221 that pull end has an epirelief, above horizontal section of sliding bolt 22 in separately the draw-in groove 222 one is a rectangle, another is right-angled triangle, the protruding of two fixture blocks 20 is provided with portion 202 outwardly dorsad along the length direction of U-shaped plate body 14, and the triangular tip 201 of two fixture blocks 20 and two variform draw-in grooves 222 fasten or break away from.Referring to Fig. 5 to Fig. 6

Using method of the present utility model is as follows:

State when two plate bodys 14 prop up at this moment, because sliding bolt 22 horizontal being inserted between two plate bodys, 14 splice ends laterally and by spring 19, fixture block 20 are blocked the compression set positions, does not move so sliding bolt 22 can axially not scurried as shown in Figure 5, and therefore, two plate bodys are direct rod shape.

When needs fold, then the two-way layback of sliding bolt is gone out, so that being separated with fixture block 20, an one draw-in groove 222 engages, also can be and break away from engaging with protruding portion 202 is upwards lifted of fixture block 20, because horizontal section of sliding bolt 22 moves in the U-shaped plate body 14 folding so another U-shaped plate body 14 can make progress fully at this moment.Referring to Fig. 6 to Fig. 8, promptly prop up state and fold into two bodies of rod fully also by state by level.
