Abstract

The utility model relates to a lapped self-locking movable scaffold, composed of a grid plate, a universal caster wheel, a lifting positioner, a transverse draw rod, an oblique draw rod, a workbench, a vertical draw rod, a continuous connecting grid plate and an auxiliary supporting rack. The height of the scaffold can be freely increased and decreased. The scaffold can be moved universally and arbitrarily on the ground, can be positioned at any position, and can be free from the limit of the planeness of the ground; the height of each support can be adjusted within limits, and the scaffold can be quickly dismounted without any tool; the scaffold is convenient to carry over, and is flexible to move after mounting, and is safe in use.

Description

Overlap joint self-locking jenny scaffold

The utility model relates to the ascend operation device, but the particularly self-locking jenny scaffold of fast construction.

In the occasion of many work high above the ground,, all need the built scaffold as the inside and outside cleaning of building trade, indoor and outdoor fitment operation, building, finishing, stage operation etc.Scaffold adopted wooden stick, plank binding mode to realize that this mode installation rate is slow more in the past, and safety is relatively poor.Have technology to adopt steel pipe to realize building of scaffold now, but this mode has the slower deficiency of installation rate equally, and easily get rusty with the fixing mode of fastener.

The purpose of this utility model is that a kind of height of design can arbitrarily increase and decrease, can on terrace, do universal moving arbitrarily, can locate everywhere, not limited by the terrace planeness, can appoint the height of transferring each supporting within the specific limits, do not need instrument, dismounting is quick, safe and reliable overlap joint self-locking jenny scaffold.

The purpose of this utility model can be achieved through the following technical solutions: design a kind of overlap joint self-locking jenny scaffold, comprise screen, universal caster wheel, lifting locator, drag link, diagonal member, workbench, vertical connecting rod and continued access screen; Screen is by two standpipes and equidistant affixed the forming of transverse tube more than two or two, and the standpipe lower end is a unthreaded hole, is provided with directed pin-and-hole, and the upper end of both sides standpipe is connected with latch, which is provided with the pin hole that matches with directed pin-and-hole; In the standpipe unthreaded hole of screen, be with lifting locator with the universal caster wheel Joint, the pivoted frame of universal caster wheel is provided with the braking locator, the screw mandrel of top and lifting locator is affixed, screw mandrel is provided with the lifting handwheel, handwheel is provided with set screw, per two top gratings are connected by the self-locking pawl that is fixed in drag link, diagonal member, vertical connecting rod top, and the self-locking pawl is made up of pawl seat, latch lock pawl and bearing pin.According to requirement for height, but the continued access screen of socket and its same structure on the screen inserts pin after the socket in pin-and-hole and pin hole corresponding with it, and puts workbench get final product on cross bar.

The utility model compared with prior art highly can arbitrarily increase and decrease, and can do universal moving on terrace arbitrarily, can locate everywhere, not limited by the terrace planeness, can appoint height of transferring each supporting, does not need the instrument fast demountable.

Below in conjunction with accompanying drawing, the utility model is described in further detail: design a kind of overlap joint self-locking jenny scaffold, include screen 5, universal caster wheel 1, lifting locator 2, drag link 3, diagonal member 4, workbench 6, vertical connecting rod 7 and continued access screen 8.Screen 5 is by two standpipes 50 and equidistant transverse tube 51 affixed forming more than two or two, and standpipe 50 lower ends are unthreaded hole, are provided with directed pin-and-hole 52, and the upper end of both sides standpipe is connected with latch 53, which is provided with the pin hole 54 that matches with directed pin-and-hole 52.In the unthreaded hole of screen standpipe, be with lifting locator 2 with universal caster wheel 1 Joint, the pivoted frame 10 of ten thousand phase castors 1 is provided with braking locator 11, the screw mandrel 20 of top and lifting locator 2 is affixed, and screw mandrel is provided with lifting handwheel 21, establishes on the handwheel and set screw 22; Lifting handwheel 21 is adjusted not at ordinary times in ground, tightens set screw 22 after determining and gets final product.Per two screens are one group, are connected by the self-locking pawl 100 that is fixed in drag link 3, diagonal member 4, vertical connecting rod 7 tops, and the self-locking pawl is made up of pawl seat 102, spring 103, lock pawl 101 and bearing pin 104; According to using requirement for height, but socket has the continued access screen 8 of same structure on the screen 5 with it, during socket the standpipe unthreaded hole is socketed in and plugs pin 200 in the latch 53, and connect drag link 3, diagonal member 4 and vertical connecting rod 7, loads onto workbench 6 and both can on drag link.When scaffold requires to build when higher, according to the demand of stability, can use aiding support frame 9 in the fastener attaching on the standpipe of screen 5, aiding support frame bottom is with the lifting locator 2 with universal caster wheel 1 Joint, behind the good aiding support frame 9 of attaching, backstay 10 gets final product in the attaching.Pin 200 can which is provided with a circular open jump ring sheet 201 as shown in Figure 7.The utility model can form with the aluminum alloy materials manufacturing.
