Description
Technical field
A kind of adjustable cat ladder is the utility model is related to, belongs to ladder field.
Background technology
When substation installs and is grounded, insulating ladder, traditional insulation need to be used on rugged road surface sometimes
Cat ladder both sides cat ladder length is the same, and insulating ladder can tilt when being placed on rugged road surface, is not easy to staff's operation,
Cat ladder may be caused to topple over when tilting serious, cause casualties accident, the rugged pavement usage cat ladder of building field
Similar problem may also be run into, so using a kind of adjustable cat ladder, foot of ladder is adjusted according to the rugged degree in road surface
The height of pin point, the level of workbench is realized, is extremely necessary.
Utility model content
The technical problems to be solved in the utility model is：A kind of adjustable cat ladder, is adjusted by the rotation of side cat ladder
Realize the adjusting of touchdown point height, to be tilted when solving the problems, such as that existing cat ladder is placed in rugged road surface, the other cat ladder
It is connected firmly, can collapses, it is portable.
The technical solution of the utility model is：A kind of adjustable cat ladder, the side foot of ladder of cat ladder is movable foot of ladder, by upper
Movable foot of ladder and lower movable foot of ladder hingedly form, and the first fixed link is hinged on movable foot of ladder, and the second fixed link is hinged on down
On movable foot of ladder, the first fixed link and the second fixed link are clamped with foot of ladder respectively during use.
Preferably, first fixed link and second fixed link one end are provided with card slot, and foot of ladder relevant position is provided with
One limit protrusion and the second limit protrusion, card slot is stuck on the first limit protrusion and the second limit protrusion during use.
Preferably, the workbench and upper movable foot of ladder and foot of ladder are hinged.
The beneficial effects of the utility model are：
Compared to original technology, after the utility model device, main advantage has：The utility model side foot of ladder is work
Dynamic connection, is adjusted by rotation the adjusting for realizing touchdown point height, to solve to tilt when existing cat ladder is placed in rugged road surface
The problem of；The cat ladder of two fixed link connection both sides, fixed form are firm；Workbench is flexibly connected with cat ladder, fixed link with
Cat ladder is flexibly connected, and can be collapsed into one when not used, portable.

Embodiment
Below in conjunction with the accompanying drawings and utility model is described further in specific embodiment：
With reference to figure 1 and Fig. 2, the technical solution of the utility model is：A kind of adjustable cat ladder, the side foot of ladder of cat ladder are
Movable foot of ladder, is hingedly formed, articulated manner connects for latch, and the first fixed link 4 is cut with scissors by upper movable foot of ladder 1 and lower movable foot of ladder 3
It is connected on movable foot of ladder 1, the second fixed link 5 is hinged on lower movable foot of ladder 3, and the first fixed link 4 and second is fixed during use
Bar 5 is clamped with foot of ladder 7 respectively, and lower activity foot of ladder 3 with left-right rotation, can realize the height of touchdown point, to adapt to using ground
It is uneven.
Described first fixed link, 4 and second fixed link, 5 one end is provided with card slot, and 7 relevant position of foot of ladder is provided with the first limit
Position protrusion 8 and second limit protrusion 6, card slot is stuck on the first limit protrusion 8 and the second limit protrusion 6 during use, living in rotation
Dynamic foot of ladder 1 and foot of ladder 7 can realize the adjusting of 9 height of workbench, and the first fixed link 4 and 5 one end of the second fixed link are provided with more
A card slot, selects different card slots to block protrusion as needed, and the first fixed link 4 is stuck on the first limit protrusion 8, and second fixes
Bar 5 is stuck on the second limit protrusion 6, realizes the stable equilibrium of cat ladder.
The workbench 9 is hinged with upper movable foot of ladder 1 and foot of ladder 7, is collapsed when not used, portable.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
