Abstract

The utility model discloses a ladder structure, it makes the ladder have the efficiency of better practicality, mainly be: the support body upper end of bisymmetry is established the combination bar pivot and is made up integratively, this built mast is established into one end and is had the portion of colluding, both ends have the recess, it sets for bit slice gomphosis in recess to correspond the groove, spacer and closure are in the support body, and prevent that the built mast breaks away from, and can make the portion's of colluding location angle, the portion of should colluding can supply to hang article, and, be equipped with the backup pad in two support body settlements department, form the support foot bar and increase endurance intensity, the foot bar of upper end is equipped with the convex part, the convex part of two support bodys can form holding of great area and put the face and supply to hold to put article, or supply the user to hold the seat. Consequently, through the utility model discloses can obtain to make the ladder to promote efficiency safe, better practicality.

Description

Ladder structure

Technical field

The utility model relates to a kind of ladder structure, its have make ladder unitized construction more firmly, increase endurance strength and use effect more easily.

Background technology

Existing ladder unitized construction, substantially as shown in Figure 1, Figure 2, Figure 3 shows, the frame body 10,11 of two symmetries, its upper end is provided with combination bore 12, combination bore 12 wears group bolt 13, and sealed with nut 14, makes the two combined integrated formation ladders of frame body 10,11, again, in frame body 10 stitching one iron nail 15 for hanging article; Above-mentioned structure, has its own shortcomings in fact:

Its two framves body 10,11 adopts bolt 13, the sealed one of nut 14, through repeatedly opening, fold two frame bodies 10,11, the problem that nut 14 loosens can be there is, it is necessary to normal inspection nut 14 is sealed, otherwise frame body 10,11 can be occurred to combine insecure and loosening, disengaging, cause and cause danger during use.

Though it has iron nail 15 for hanging article, but, this iron nail 15 has the danger come off, and article still can because being shaken and slippage goes out to drop.

Treadle 16 (as shown in Figure 2) topmost is protruded in its body 10,11 upper end, causes inconvenient bearing article or user to be inconvenient to be seated on treadle 16.

As shown in Figure 3, when two frame bodies 10,11 fold, the body of rod of two frame bodies 10,11 is mutually closely sealed, has the phenomenon compeling plug, causes and be inconvenient to open two frame bodies 10,11.

Practical novel content

Namely the utility model is for improving above-mentioned existing shortcoming, the unitized construction that its object is to make ladder more firmly, increase endurance strength and use more convenient.

In order to achieve the above object, the utility model provides a kind of ladder structure, two frame body upper ends have combination bore, being combined into one by combination bar pivot, this combination bar is set as one end and is provided with groove, sets bit slice at respective slot place, this location sheet is set as has profile groove, the profile groove of location sheet is embedded in the groove of combination bar, and this location sheet also schedules frame body by screw lock, departs to limit combination bar.

Preferably, this combination bar one end has hook part for hanging article.

Preferably, this two framves body treadle topmost has protuberance, and the height of its protuberance is slightly higher than two frame body upper ends.

Preferably, between this two framves body, it is provided with pad, so that leaving gap when two frame bodies fold.

Preferably, the treadle of this two framves body central part is provided with back up pad supplemental support.

The beneficial effects of the utility model are: can guarantee that combination bar does not loosen and depart from, and guarantee combine bar hook part upwards, hanging article do not come off, and it is provided with back up pad to support treadle and increase endurance strength, the treadle of the top is also provided with protuberance, the supporting face forming larger area for conveniently putting article or is sat for user, promotes safe, easy to use.

Embodiment

Refer to Fig. 4, Fig. 5, Fig. 6, it is combined integrated by combination bar 30 pivot that two frame body 20,21 upper ends have combination bore 22, this combination bar 30 is set as that one end has hook part 32, two ends are provided with groove 31, bit slice 33 is set in respective slot 31 place, this location sheet 33 is set as has profile groove 34, the profile groove 34 of location sheet 33 is embedded in the groove 31 of combination bar 30, and this location sheet 33 is also locked in frame body 20,21 with screw 35; This body 20,21 treadle 23 topmost is provided with protuberance 24, and the height of protuberance 24 is slightly higher than frame body 20,21 upper end, and the protuberance 24 of two frame bodies 20,21 the top treadles 23 forms the supporting face W of larger area; It is provided with pad 36 between this two framves body 20,21 upper end combination place, and when two frame bodies 20,21 must be made to fold, still leaves gap H; Separately, the treadle 23 at this two framves body 20,21 setting height place is provided with back up pad 25, and back up pad 25 is supported in treadle 23.

According to above-mentioned structure, it is possible to obtain following effect, advantage:

As shown in Figure 5, Figure 6, the combination bar 30 combining two frame bodies 20,21 is limited by location sheet 33, and locate sheet 33 and establish profile groove 34 to be embedded in the groove 31 of combination bar 30, instead of (threaded) combination with bolt, nut, therefore, not having and cause problem loosening, that depart from because repeatedly folding, open, security is good.

This combination bar 30 has hook part 32 for hanging article, and, be provided with groove 31 because of combination bar 30 and be fitted together to by locating the profile groove 34 of sheet 33, it is possible to have limit hook part 32 upwards, downward effect can not be turned to, and must prevent article slippage from going out the effect dropped.

As shown in Figure 6, it is provided with pad 36 between two frame bodies 20,21 so that when two frame bodies 20,21 fold, still leave gap H, does not have and compel to fill in the problem blocked, there is convenient effect opening two frame bodies 20,21 again.

As shown in Figure 5, the treadle 23 of two frame bodies 20,21 the tops has protuberance 24 so that form a supporting face W in upper end, it is provided that bearing article or confession user's landing.

As shown in Figure 5, the treadle 23 of two frame body 20,21 central parts is provided with back up pad 25, so that increase the endurance strength of treadle 23.

In sum, structure of the present utility model, really has extremely good practicality and promotes effect.
