Description

Ladder servicing unit

Technical field

The present invention relates to a kind of ladder, more particularly to a kind of ladder servicing unit.

Background technology

Existing ladder is mainly stepped on by two spaced longitudinal mobile jibs, and a plurality of therefore between two longitudinal mobile jib transverse direction Plate is formed, and user can hold longitudinal mobile jib, rides the action that horizontal pedal is ascended a height, and the help by ladder makes The shorter people of height can take and be positioned over the thing of higher position, or carry out the construction operation of eminence.

Although above-mentioned ladder can allow user smoothly to reach required height, in the state of the non-flat forms of floor, user can Ladder can not be used because of terrain obstruction, such as：Stair, or the height deficiency of ladder, even and if causing user Climb to ladder highest point, can not still reach required height cause to take eminence thing or carry out the construction of eminence Operation.Furthermore existing ladder can not voluntarily adjust height with the demand of user so that user is often for difference Environmental requirement and need to prepare the ladder of various different heights to be replaced, the not only space-consuming in storage, also increase makes The burden of user.

The content of the invention

It is an object of the present invention to when user faces the ground of non-flat forms, can be made adjustment in response to different terrain, and It can be applied on known ladder.

To reach above-mentioned purpose, the present invention provides a kind of ladder servicing unit, vertical with least two suitable for a ladder, the ladder Included to mobile jib, and a plurality of horizontal treadles being located between two mobile jibs, the ladder servicing unit：

One fixed cell, adapter section and at least one with a longitudinal mobile jib for being incorporated into the ladder are fixed on the guiding of the adapter section Part；

One adjustment unit, the adjustment unit are column, and the guide member is incorporated into a manner of it can be moved relative to the fixed cell；With And

Locating unit, for after the adjustment unit is moved to a precalculated position, the adjustment unit to be fixed on into the fixed cell.

Reach by components above when user faces the ground of non-flat forms, can be made adjustment because of different terrain, and can apply In on known ladder.

Embodiment

Clear, complete description is carried out to technical scheme below in conjunction with accompanying drawing, it is clear that described embodiment is The part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people The every other embodiment that member is obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.

Fig. 1 to Fig. 3 is referred to, the present invention is a kind of ladder servicing unit, and suitable for a ladder 10, the ladder 10 has at least Two longitudinal mobile jibs 11, and a plurality of horizontal treadles 12 being located between two mobile jibs, the ladder servicing unit include：

One fixed cell 20, the adapter section 21 and two with a longitudinal mobile jib 11 for being incorporated into the ladder 10 are fixed on the combination The guide member 22 of section 21, the adapter section 21 of the fixed cell 20 is L-shaped by plate body bending in the present embodiment, respectively should Guide member 22 is a square frame, and its center has a perforation 221, and the adapter section 21 is to be fixed with two-screw A through this Screw lock is fixed after unit 20 and longitudinal mobile jib 11；

One adjustment unit 30, the adjustment unit 30 are column, have the 221 corresponding shape of perforation with such guide member 22, Passed through for the adjustment unit 30, the guide member 22 is incorporated into a manner of it can be moved relative to the fixed cell 20, in the present embodiment In one end of the adjustment unit 30 there is an on-slip pin 31, the adjustment unit 30 is provided with a plurality of adjustment holes 32；And

Locating unit 40, for after the adjustment unit 30 is moved to a precalculated position, the adjustment unit 30 to be fixed on into this Fixed cell 20, the positioning unit 40 is with an adapter section 21 with welding manner located at the fixed cell 20 in the present embodiment Fixed seat 41, one latch 42, one of the guide member 22 be movable to located at the fixed seat 41 and its one end be located at the latch 42 pad 43, one is sheathed on the latch 42 and its both ends resilient abutment fixed seat 41 with the pad 43 to provide an elastic force The spring 44 for allowing the latch 42 to be moved toward the guide member 22, and the latch 42 has a draw ring adjacent to one end of the fixed seat 41 45, inserted by the latch 42 in any one of such adjustment hole 32 of adjustment unit 30, to fix the adjustment unit 30.

It is above the structure of the present invention, and the occupation mode of the present invention is as described below：

Refer to Fig. 3 and Fig. 4, when user be intended to using it is of the invention when, then first with two-screw A by the combination of the fixed cell 20 Section 21 and longitudinal secure bond of mobile jib 11, then the adjustment unit 30 is incorporated into the guide member 22 and slides into predetermined altitude Afterwards, then as shown in figure 5, user can move the latch 42 by the draw ring 45, make that the latch 42 departs from or bolt-lock enters this The perforation 221 of guide member 22 and a adjustment unit 30 wherein adjustment hole 32, thereby reach the longitudinal direction master for extending the ladder 10 The length of bar 11, as shown in fig. 6, user can be adjusted with reference to the ladder servicing unit from respectively longitudinal mobile jib 11, adjustment The respectively adjustment unit 30 of the ladder servicing unit, make the length that respectively longitudinal mobile jib 11 extends inconsistent, and enable the ladder 10 It is enough steadily to stand on the landform such as stair by the adjustment unit 30 of the respectively ladder servicing unit.
