Abstract

The utility model provides a ladder which can be used as the rack, the hanger, etc., and is the multi-function folding ladder. The utility model is mainly composed of a connecting plate, a supporting frame, a yoke plate, a supporting frame transverse rod, a folding switch, etc., and wherein, the folding switch is mainly composed of a lock catch pin, a lock catch frame, a joint panel, a pin axle, a core board, springs, the plastic stuffing, etc. The height of the ladder which adopts the utility model can be changed discretionarily, the changing of the ladder is flexible, the volume is small, the weight is light, the material consuming is less, and the occupation area is small. The utility model not only can be used as the ladder, but also can be used as the rack, the hanger, etc., and can carry out the folding by self.

Description

Multifunctional foldable ladder

What the utility model provided is a kind of ladder---Foldable multifunctional ladder that can be used as thing frame, hanger etc. again easily.

Existing ladder mainly is made up of the connection lath of the rack cross-bar that plays beam effect, support, screw rod and a booster action.It mainly has been the effect of ladder.Also have liftable function, what they had also is to have ladder not of uniform size to combine, and they are to utilize rope to carry out lifting, fixing.Yet their height is unmodifiable often, is absolutely unsafe even its structure of the ladder of alterable height seems complicated and uses, and they also have shortcomings such as area occupied is big, the consumption material is many, volume big, weight is heavier.

The purpose of this utility model is the problem at above-mentioned existence, propose a kind of novel multifunctional folding ladder, it have the height can change arbitrarily, its variation is more flexible, characteristics such as the area that volume is little, in light weight, consumptive material is few and take is also little, but it not only can make ladder, crop frame, hanger again, and it can utilize and self folds.

Accompanying drawing 1 is a structure side view of the present utility model.Explain the book extract accompanying drawing again.

Accompanying drawing 2 is folding switch structural representations of the present utility model.

Accompanying drawing 3 is lateral views of folding switch.

Accompanying drawing 4 is structure elevations of the present utility model.

Accompanying drawing 5 is sectional views of rack cross-bar.

Provide technical solution of the present utility model below in conjunction with accompanying drawing:

Structure is shown in accompanying drawing 1-5.Compositions such as the gusset piece 2 of booster action, the support 3 that plays the girder effect, screw rod 4, rack cross-bar 5, screw 15, yoke plate 16, rubber sleeve 1 and folding switch 25 have been mainly contained.Rack cross-bar 5 is hollow profiles, and in hollow profile, be provided with a screw rod guide rail 27, screw rod 4 just be through the screw rod guide rail hollow 28 in, the screw rod guide rail has played one and can be arranged on the support of ladder two sides by stressed in any direction folding switch 25, there are 3 pairs, and symmetrical in twos.Support 3 connects by connection arm 26 with switch 25.Folding switch wherein has the snap close frame 6 of supporting snap close pin 7, snap close pin 7 be the location and be provided in a side of snap close frame 6 upper and lower, at snap close frame middle part pin 11 is arranged, pin 11 is arranged on the bearing pin 12, also had the articular lamella 8 that connects between the ladder, filler 10, what mainly fill out in this filler 10 is plastics, its plastics are fixing by rivet 9.Filler 19 is located at the upper end of switch 25.Lock shaft 12 is to connect snap close frame 6, playing the spring 13 of locking reset response is pushed down by spring cup 14, spring cup 14 is located at the right side of bearing pin 12, central layer 17 is arranged in the middle of folding switch, it is the locking effect that has been used for adjusting roman, central layer two sides have filler 19, are plastics in the filler, and plastics are to fix by rivet equally.Filler 19 is located at the bottom of switch 25.Linked switch sheet 20, articular lamella 8 all are located in the connection arm 26,20 of linked switch sheets make the snap close pin guarantee to join arm and join between arm in the middle of the connection arm an appropriate gap, be unlikely the distortion of connection arm, be located at the extension spring post 21 of connection on the arm and be fixedly extension spring 22, extension spring 22 is that central layer 17 is resetted, and the central layer sleeve 23 that is provided with on central layer 17 mainly has been effect attractive in appearance.The utility model is to be assembled by a plurality of small-sized ladders, and its disassembly and assembly makes things convenient for, is convenient to the folding voluntarily assembling of user, and each small-sized ladder can make up, connects, fold.

Adopt the utility model, except that the function that keeps ladder, but also double as thing frame, hanger, it utilizes and self folds, do not need other cooperation means, can extend several meters from one meter, also can hang up the high building wall and construct outward, can put into car runk after folding, it has variation highly arbitrarily, and changes advantages such as flexible, that volume is little, in light weight, consumptive material is few, area occupied is little.
