Abstract
The utility model relates to a locking variable-angle multipurpose ladder. The utility model is characterized in that a plurality of main ladders are connected by hinge connecting rods, each connecting place is accompanied with a set of locking devices which are mainly composed of a lock sheet, a control lock sheet, a control lock rod, an opening sheet, a spring, a lock head, a pulley positioning sheet and drawing wires, and a plurality of lock holes ranged on the lock sheet correspond to the lock head in the control lock rod in the locking devices to reach a variable-angle locking goal. The utility model has the characteristics of variable locking angles, big bearing pressure and high safety performance.
Description
The utility model relates to a kind of angle multipurpose ladder of locking.
On September 13rd, 1991, China's utility model patent communique discloses a kind of " multifunctional ladder " (notification number: technical scheme CN2069918U), its structure is made up of a plurality of main ladders, between the main ladder of every adjacent two joints connecting piece is housed, be to be installed with the hinge bar between terraced epimere and the terraced hypomere, its weak point is can not lock after the ladder knuckle is shaped, therefore, when bearing big pressure, security performance is affected.
The purpose of this utility model is to provide a kind of angle multipurpose ladder of locking, and all locks device with a cover between each junction ladder epimere between its a plurality of main ladders and the terraced hypomere, can be locked after the moulding of ladder knuckle.Therefore, increased the pressure that ladder can bear, security performance also is improved.
Task of the present utility model is finished like this: locking plate fixedly is equipped with in the outside at terraced epimere, the control locking plate fixedly is equipped with in the inboard of ladder hypomere, hinge-rod is fixed in a pair of corresponding aperture of locking plate and control locking plate, the ladder hypomere fixedly is equipped with a hollow control locking bar by the control locking plate, spring is equipped with at the middle part in the control locking bar pipe, lock pin is equipped with at two ends, one of suit is opened sheet and is connected with unlatching sheet center of circle alignment pin with the control locking bar on the control locking bar, top and the following straight line slotted eye that two arc-shaped slots is respectively arranged and control on the locking bar of unlatching sheet is corresponding, the arc-shaped slot that unlatching draws pin to pass in the unlatching is fixed on the lock pin with the straight line slotted eye of controlling on the locking bar, fixing pulley spacer of suit also on the control locking bar, be equipped with one with the pulley alignment pin on the pulley spacer and open pulley, one end of a wire drawing is equipped with wire drawing connecting hole sheet, pass the wire drawing hole of opening the sheet side, overcoat wire drawing sleeve pipe after walking around the local edge pulley of unlatching and passing the endoporus that is inlaid in a set of cups on the pulley spacer, be that the garden heart is arranged several lockholes with hinge bar patchhole on the locking plate, the lockhole of locking plate can be inserted in the termination of lock pin.
The utility model compared with prior art has the variable-angle lockable, bears the characteristics that pressure is big, security performance is high.
Detailed enforcement of the present utility model will provide in conjunction with the accompanying drawings:
Fig. 1 is the structure chart that can lock the junction of terraced epimere and terraced hypomere in the angle multipurpose ladder;
Fig. 2 is the part vertical view that can lock angle multipurpose ladder central controlled lock bar;
Fig. 3 is the corresponding relation figure that can lock angle multipurpose ladder locking plate and control locking plate.
Locking plate (1) fixedly is equipped with in the outside at terraced epimere (2) of each junction between a plurality of main ladders, control locking plate (3) fixedly is equipped with in the inboard of ladder hypomere (18), hinge-rod (4) is fixed in a pair of corresponding aperture of locking plate (1) and control locking plate (3), ladder hypomere (18) fixedly is equipped with a hollow control locking bar (5) by control locking plate (3), spring (6) is equipped with at the middle part in control locking bar (5) pipe, lock pin (9) is equipped with at two ends, control locking bar (5) is gone up suit unlatching sheet (16) and is connected with opening sheet center of circle alignment pin (17) with control locking bar (5), top and the following straight line slotted eye that two arc-shaped slots is respectively arranged and control on the locking bar (5) of unlatching sheet (16) is corresponding, unlatching draws pin (14) to pass, and arc-shaped slot of opening on the sheet (16) and the straight line slotted eye of controlling on the locking bar (5) are fixed on the lock pin (9), a fixing pulley spacer of suit (13) also in control locking bar (5), pulley spacer (13) is gone up with pulley alignment pin (8) a unlatching pulley (12) is housed, one end of a wire drawing (7) is equipped with wire drawing connecting hole sheet (15), pass the wire drawing hole of opening sheet (16) side, overcoat wire drawing sleeve pipe (10) after walking around the local edge of opening pulley (12) and passing the endoporus of a set of cups (11) that is inlaid on the pulley spacer, it is that the garden heart is arranged several lockholes that locking plate (1) is gone up with hinge bar (4) patchhole, and the lockhole of locking plate (1) can be inserted in the termination of lock pin (9).
When affecting wire drawing sleeve pipe (10), wire drawing (7) affects opens sheet (16) and rotates and drive to open and draw pin (14) along control locking bar (5) moving linearly, the tension force that affects lock pin (9) to overcome spring (6) simultaneously inwardly shrinks, break away from locking plate (1), promptly collapsible between ladder epimere (2) and the terraced hypomere (18), a certain locating hole on locking plate (1) and tapered end (9) position are at once, lock pin under the tension force of spring (6) (9) inserts the hole of locking plate (1), the angle of ladder is promptly locked, thereby has reached the purpose of this utility model.
