Description
Technical field
The utility model relate to folding ladder manufacture field, specifically a kind of security performance high, save manpower, loft folding ladder easy to use.
Background technology
Loft folding ladder common at present has two kinds of forms, one stretches to draw ladder, appearance is similar to accordion, by the structure that hinged formation is all linked with one another, although handsome in appearance, simple and convenient, but do not have to climb the place held up for old man and child, safety intersects, another kind of is segmentation ladder, and segmentation ladder mostly is syllogic segmentation ladder, and the first ladder section is wherein installed on the cover board, cover plate and framework are hinged, the various piece link of segmented ladder is hinged, and time no, can fold up.Although segmented folding ladder lands stable, be convenient to climbing, between each section, only lean on hinge type anatomical connectivity, in the process of having put, the not controlled spontaneous spontaneous situation about opening of not controlled exhibition of lower end ladder may be occurred, unexpected injury is caused to user.
Summary of the invention
In order to solve deficiency of the prior art, the utility model aim to provide a kind of security performance high, save manpower, loft folding ladder easy to use.
The utility model is achieved through the following technical solutions:
A kind of loft folding ladder, comprise enclosing cover, ladder section, ladder section is connected with the gripper shoe be connected through pedal by pedal, folding ladder is provided with multiple ladder section from top to down, engage through hinge type structure between adjacent steps section, wherein the framework of enclosing cover upper end and ceiling opening part is hinged, ladder section upper end and the enclosing cover Stationary liquid of the top are hinged, it is characterized in that enclosing cover is left, right both sides are respectively equipped with brute spring, brute spring one end and enclosing cover are fixedly linked, the brute spring other end is connected with framework, folding ladder is left, the gripper shoe lateral wall of right both sides is provided with elastic force unit, elastic force unit establishes the telescopic mechanism of spring in being, the upper and lower two ends of elastic force unit are hinged with the gripper shoe of adjacent two ladder sections respectively.
Elastic force unit described in the utility model comprises outside loop bar and inner shaft, outside loop bar inner chamber is provided with spring, cylindrical slider, the inner shaft part body of rod, wherein spring one end is connected with outside loop bar upper end, the spring other end is connected with cylindrical slider, slide block and outside loop bar lower wall are respectively equipped with the first pilot hole and the second pilot hole that coordinate inner tube to slide, inner shaft upper end is provided with block, and the inner shaft lower end body of rod slides in inner shaft through the first pilot hole, the second pilot hole successively.
The axis of outside loop bar described in the utility model, spring and inner shaft on same straight line, to ensure the outside loop bar in elastic force unit, the cooperation between inner shaft and spring.
Enclosing cover upper end described in the utility model is provided with balustrade, climbs to facilitate user.
The utility model is not only left at enclosing cover, right both sides are provided with brute spring respectively, turn up rear user upwards slough enclosing cover power used to reduce folding ladder, and left at folding ladder, the gripper shoe lateral wall of right both sides is provided with elastic force unit, under complete contraction state, spring in elastic force unit is in substantially does not have deformation, when in the process that folding ladder is in expansion or folding and unfolding, spring produces deformation because coupled cylindrical slider is stretched by inner shaft, and then pulling force is produced to lower end ladder section, the not controlled spontaneous spontaneous situation about opening of not controlled exhibition of the lower end ladder when packing up or put down folding ladder can be prevented, unexpected injury is caused to user, there is security performance high, save manpower, the structure such as easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation under elastic force unit contraction state.
Fig. 3 is the structural representation that elastic force unit is stretched under state.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in the figure, a kind of loft folding ladder, comprise enclosing cover 1, ladder section 2, the gripper shoe 4 that ladder section 2 is connected with through pedal by pedal 3 is connected, folding ladder can be provided with multiple ladder section 2 from top to down, but be preferably syllogic folding ladder, engage through hinge type structure between adjacent steps section 2, wherein the framework 5 of enclosing cover 1 upper end and ceiling opening part is hinged, ladder section upper end and enclosing cover 1 Stationary liquid of the top are hinged, enclosing cover 1 upper end is provided with balustrade, climb to facilitate user, it is characterized in that enclosing cover is left, right both sides are respectively equipped with brute spring 6, brute spring 6 one end and enclosing cover 1 are fixedly linked, brute spring 6 other end is connected with framework 5, folding ladder is left, the gripper shoe lateral wall of right both sides is provided with elastic force unit, elastic force unit establishes the telescopic mechanism of spring 7 in being, on elastic force unit, lower two ends are hinged with the gripper shoe of adjacent two ladder sections respectively, elastic force unit comprises outside loop bar 8 and inner shaft 9, outside loop bar inner chamber is provided with spring, cylindrical slider 10, the inner shaft part body of rod, outside loop bar, the axis of spring 7 and inner shaft 9 is on same straight line, to ensure the outside loop bar 8 in elastic force unit, cooperation between inner shaft 9 and spring 7, wherein spring 7 one end is connected with outside loop bar upper end, spring 7 other end is connected with cylindrical slider 10, slide block 10 and outside loop bar 8 lower wall are respectively equipped with the first pilot hole and the second pilot hole that coordinate inner tube to slide, inner shaft upper end is provided with block 11, the inner shaft lower end body of rod is successively through the first pilot hole, second pilot hole slides in inner shaft.
The utility model is not only left at enclosing cover, right both sides are provided with brute spring respectively, turn up rear user upwards slough enclosing cover power used to reduce folding ladder, and left at folding ladder, the gripper shoe lateral wall of right both sides is provided with elastic force unit, under complete contraction state, spring in elastic force unit is in substantially does not have deformation, when in the process that folding ladder is in expansion or folding and unfolding, spring produces deformation because coupled cylindrical slider is stretched by inner shaft, and then pulling force is produced to lower end ladder section, the not controlled spontaneous spontaneous situation about opening of not controlled exhibition of the lower end ladder when packing up or put down folding ladder can be prevented, unexpected injury is caused to user, there is security performance high, save manpower, the structure such as easy to use.
