Abstract
The utility model relates to a device used for containing an extension ladder in an attic. The device comprises a support, a strong tension spring, a connecting bar, a front connecting pipe, a rear connecting pipe, a locating shaft, a rotating shaft pin, a screw and a locating rivet; the support is fixed onto a wooden plate which is fixed to an opening part of the attic and is connected with the extension ladder and the strong tension spring through the front connecting pipe and the rear connecting pipe; when a door sheet is upwards closed, the hands can release while reaching a 3/5 position, and the support of the ladder can be automatically contained into the attic under the effect of the spring force; and adjusting holes used for fine adjusting the height are formed in the connecting pipes, in order to adapt to attics of different heights. According to the device used for containing the extension ladder in the attic, the characteristics of the extension ladder are innovatively and ingeniously combined, and the mechanical principle is utilized, in order to realize the semi-automatic containing of the ladder into the attic; the ladder of the attic is avoided messing and impacting on the life anymore with such changes; and furthermore, the ladder of the attic is fashionable, graceful and brings the sense of science and technology.
Description
Technical field
The utility model relates to a kind of device of taking in extension ladder, particularly relates to a kind of at loft, taking in the device of extension ladder.
Background technology
At present, taking in ladder at loft, is generally to adopt non-telescoping ladder to be fixed in the loft mouth or to adopt DYN dynamic multi-section structure, and it is in disorder that such mode of taking in is placed loft ladder, hinders the action of living environment, inconvenience and consumption power during use.
Summary of the invention
For overcoming the defect of prior art, it is a kind of at loft, taking in the device of extension ladder that the utility model provides.For achieving the above object, the utility model adopts following technical scheme:
A kind of at loft, taking in the device of extension ladder, comprising: support; Powerful extension spring; Pitman; Front tube connector; Rear tube connector; Locating shaft; Roller pin; Screw; Quilting rivet.It is characterized in that: described support is fixed on the plank of loft opening part, by forward and backward tube connector, be connected with powerful extension spring with extension ladder, when door-plate upwards folds, can let go in the position to 3/5, and the support of ladder can pass through the effect automatic accomodation of spring force on loft.The adjustment hole of regulating height is arranged, to adapt to highly different loft on tube connector.
Described forward and backward tube connector is connected with support by pitman, and junction is fixed by roller pin.
Described powerful extension spring is connected on support and rear tube connector by described locating shaft and described quilting rivet.
The beneficial effects of the utility model; The innovation of this product is in conjunction with the characteristics of extension ladder, to utilize theory of mechanics can automanually complete the action folded to loft dexterously, because this change makes the no longer in disorder obstruction life of the stair of loft, make simultaneously the loft ladder graceful rich science and technology sense of fashion that becomes.
