Abstract
The utility model relates to a wall automatic locking foldable frame which is composed of a vertical rod 1, a slant stay rod 2 and a cross rod 3, wherein a positioning slide way 4 which forms an acute angle in a vertical direction is arranged on the vertical rod 1; sliding pins of a connection rod 5 are clamped in the positioning slide way and are movable; the slide way 10 is arranged on the vertical rod 1; a pin shaft 9 is clamped in the slide way 10 and slides; the foldable frame is unfolded or folded by the effect of the connection rod 5. The wall automatic locking foldable frame with the advantage of convenient operation is labor saving and time saving in the folding and the unfolding, and can be used for the folding or unfolding of desks, chairs, shelves or top hung type windows.
Description
The utility model relates to a kind of automatic locking folding stand of wall type that can be used for desk, chair, shelf or suspension type window etc.
Existing folding stand generally is made of montant, cross bar and hound, slots on montant, and folding stand can be folded, but when folding stand is dug, glide to prevent hound with tightening the bolt that is stuck on the montant groove, and it is very inconvenient to waste time and energy during use.
The purpose of this utility model just provides and a kind ofly fold, locking automatically when opening, and is time saving and energy saving, the automatic locking folding stand of wall type easy to use.
Solution of the present utility model is such: be to be made of montant 1, hound 2, cross bar 3, montant 1 is hinged with an end of cross bar 3, the two ends of hound 2 are hinged with montant 1, cross bar 3 respectively, have on montant 1 and the acutangulate positioning runner 4 of vertical direction, the sliding pin 8 on the connecting rod 5 is to be stuck in the positioning runner 4 and removable; Have chute 10 on the montant 1, bearing pin 9 is to be stuck in the chute 10; When connecting rod 5 was in free state, bearing pin 9 and moves to the upper end, bearing pin 9 was withstood in the upper end of connecting rod 5.Thereby when shelf is folded, only with hand promotes connecting rod 5 motions, abdicates chute 10, lifts cross bar 3, when bearing pin 9 can withstand connecting rod 5, just can unclamp hand, lift cross bar 3, bearing pin 9 just can move to the upper end along chute 10, connecting rod 5 moves down under the deadweight effect, be in free state, bearing pin 9 is withstood and locked in the upper end of connecting rod 5, thereby realize that shelf is folding.
The utility model has the advantages that folding, locking automatically when opening, time saving and energy saving, easy to use.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the structural representation of the utility model when folding.
Accompanying drawing 2 is the utility model structural representations when opening.
Accompanying drawing 3 is the structural representations when adopting two the utility model supporting bable tops.
Accompanying drawing 4 is structural representations of montant 1.
Accompanying drawing 5 is that the utility model is made the adjustable structural representation in folding position.
The utility model is made up of montant 1, hound 2, cross bar 3, positioning runner 4, connecting rod 5, switch pin 6, rotary switch 7, sliding pin 8, bearing pin 9.
Constitute the utility model by montant 1, hound 2, cross bar 3, montant 1 is hinged with an end of cross bar 3, the two ends of hound 2 are hinged with montant 1, cross bar 3 respectively, have on montant 1 and the acutangulate positioning runner 4 of vertical direction, and the sliding pin 8 on the connecting rod 5 is to be stuck in the positioning runner 4 and removable; Have chute 10 on the montant 1, bearing pin 9 is to be stuck in the chute 10; When connecting rod 5 was in free state, bearing pin 9 and moves to the upper end, bearing pin 9 was withstood in the upper end of connecting rod 5.The distance that can place bearing pin 9 is left in the bottom of the bottom of connecting rod 5 and chute 10.
Sliding pin 8 on the connecting rod 5 adopts two at least, and two sliding pins 8 are vertically to move to keep connecting rod 5 one on the other, and bearing pin 9 can be moved up and down along the chute on the montant 1 10 easily.Connecting rod 5 is provided with switch pin 6, is beneficial to stir connecting rod 5 and moves.
When two folding stand supporting bable tops shown in the employing accompanying drawing 3, be handled easily, be hinged with rotary switch 7, switch pin 6 is to join with the rotary switch 7 that is hinged on the montant 1, rotation turn switch 7, can stir two switch pins 6 on the folding stand simultaneously, drivening rod 5 moves, and realizes folding and opening.
When the folded state shown in the accompanying drawing 1, bearing pin 9 is in the upper end of chute 10, and connecting rod 5 falls by deadweight, blocks bearing pin 9, thereby can keep folded state; In the time of need opening, stir connecting rod 5 with hand, it is moved along chute 10, abdicate the downslide passage of bearing pin 9, bearing pin 9 glides, thereby shelf can be positioned over the state shown in the accompanying drawing 2.In the structure shown in the accompanying drawing 3, by rotary switch 7, can stir two switch pins 6 on the folding stand simultaneously, control that two folding stands are opened or folding.
If the upper end of the vertical edge of connecting rod 5 and chute 10 are certain angle (as shown in Figure 5), then bearing pin 9 can be withstood by vertical edge and rest on arbitrary position, makes cross bar 3 can rest on unspecified angle, and this kind structure is particularly suitable for doing window-frame and uses.
