Abstract

The utility model relates to an extension door, which provided with a frame. The frame has a pulley on bottom and is processed with upper shaft holes and lower shaft holes, both are internally provided with an upper and a lower shafts, both of which are respectively fixed with a connecting plate sheet in the middle; annular seats are arranged at two sides of the connecting plate sheets, which of the adjacent connecting plate sheet are mutual occluded and movable connected through a bolt; torsional springs are suited at lower ends of the upper and lower shafts, which are externally suited with outer pipes and are respectively fixed on the connecting plate sheets and the frames with the upper end lower ends. The utility model has the advantages of simple structure, convenient transportation and storage and speedy and facial construction on site, which can produce normalized products in large amount, thus lowering the production and installation cost.

Description

Retractable door

Technical field

The utility model relates to a kind of retractable door, especially a kind of rapid, simple and direct retractable door is installed.

Background technology

The common retractable door that is installed in factory, unit, dwelling house and separated region, when installation, all need prior measurement size, arrive the other "one off" production of production plant's sized again, and the crane assembling of still needing when installing, very inconvenience, can't form a large amount of production export trades, installation personnel also needs a lot, causes the high deficiency of cost.

Summary of the invention

In order to overcome the deficiency of above-mentioned technology, the utility model provides a kind of normalization member of producing earlier in factory, also needs the retractable door of quick and convenient assembling when the time comes according to the job site.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of retractable door, be provided with framework, the framework bottom is provided with pulley, be processed with upper shaft hole and lower shaft hole on the framework, in upper shaft hole and the lower shaft hole lower shaft is installed, the middle part of last lower shaft is fixed with the connection plate, connect the plate both sides and be provided with ring seat, the ring seat of each adjacent connection plate flexibly connects through the mutual interlock of latch, the lower end of last lower shaft is set with torsion spring, torsion spring is with outer tube outward, and the two ends up and down of torsion spring are separately fixed at and connect on plate and the framework.

The beneficial effects of the utility model are, simple in structure, transportation, store convenient, at the scene construction more rapidly, convenient, the product of production specificationization has in a large number reduced production and installation cost again.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an exploded view of the present utility model.

Fig. 2 is that the utility model launches top view.

Fig. 3 is that the utility model launches elevation.

1. frameworks among the figure 2. connect plate, 10. guided way, 11. pulleys, 12. upper shaft holes, 13. lower shaft holes, lower shaft on 21., 22. annular grooves, 23. keepers, 24. rigid bearings, 25. ring seats, 26. latches, 27. torsion springs, 28. outer tubes.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model includes members such as a framework 1, connection plate 2, framework 1 can be made into different shape, be provided with pulley 11 in its bottom, framework 1 can be slided on guided way 10, be processed with upper shaft hole 12, lower shaft hole 13 on the framework 1, in upper shaft hole 12 and the lower shaft hole 13 lower shaft 21 is installed, the middle part of last lower shaft 21 is fixed with and connects plate 2, makes to connect plate 2 according to

upper shaft hole

12,13 one-tenth position rotating of lower shaft hole.

Connect the last lower shaft 21 that plate 2 is provided with one, and be fixed with " C " shape keeper 23 and bearing 24 successively on the annular groove 22 at last lower shaft two ends about in the of 21, make in the upper shaft hole 12 that connects plate 2 and be positioned in framework 1, the lower shaft hole 13, and last lower shaft 21 can be position rotating in upper shaft hole 12, lower shaft hole 13, connect plate 2 both sides and be provided with ring seat 25, adjacent connection plate 2 is also flexibly connected through latch 26 mutual interlocks by the ring seat 25 of each adjacent connection plate 2.Can make again and connect plate 2 when folding, fishplate bar sheet 2 can become certain orientation to fold, and is with torsion spring 27 and outer tube 28 on the last lower shaft 21 of connection plate 2, and torsion spring 27 two ends are positioned at respectively and connect on plate 2 and the framework 1, according to the different spiral shells of torsion spring 27 to, make to connect plate 2 and have the function that resets.

The utility model utilizes a plurality of frameworks 1 to be connected by connection plate in the middle of it 2, so each framework 1 can stand on the guided way 10 and slide, and several frameworks 1 are connected the back and form a body, and this switch can be arranged to beginning, whole limit by framework; Also can be provided with dynamical element, each framework that is pulled is walked on guided way 10, makes each framework 1 be collected into less thickness and its and connects plate 2 and can fold around latch 26 rotations.

Claims

1, a kind of retractable door, be provided with framework, the framework bottom is provided with pulley, it is characterized in that: be processed with upper shaft hole and lower shaft hole on the framework, in upper shaft hole and the lower shaft hole lower shaft be installed, the middle part of last lower shaft is fixed with the connection plate, connect the plate both sides and be provided with ring seat, the ring seat of each adjacent connection plate flexibly connects through the mutual interlock of latch, and the lower end of last lower shaft is set with torsion spring, torsion spring is with outer tube outward, and the two ends up and down of torsion spring are separately fixed at and connect on plate and the framework.
