Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of frock ladder, including base, pedal 1 and bracket component, pedal 1 is arranged parallel to base,
Frame component includes the head rod 2 being hinged with base and the second connecting rod 3, and head rod 2 is parallel with the second connecting rod 3
Arrange, the two ends of pedal 1 are hinged with head rod 2 and the second connecting rod 3 respectively, base, pedal 1, head rod 2 and the
Two connecting rods 3 form parallel-crank mechanism by hinge, and this parallel-crank mechanism causes no matter how bracket component turns
Dynamic, pedal 1 all keeps parallel with base, and hence for the corrugated bulkhead of different gradient, workmen can steadily stand in pedal 1
Upper construction.
Base includes that fixed seat 4 and Mobile base 5, Mobile base 5 are partially provided in fixed seat 4, and 5 bottom of Mobile base is provided with
Roller 6, Mobile base 5 are connected by positioning guide mechanism with fixed seat 4, are provided with locking mechanism between Mobile base 5 and fixed seat 4,
Positioning guide mechanism prevents Mobile base 5 from rocking during movement, and locking mechanism is used for for Mobile base 5 being locked to required position
Put.
Bracket component is at least two groups, includes a head rod 2 and second connecting rod 3 per pack support component,
Bracket component be arranged in parallel, and each pack support component forms parallel-crank mechanism with base, pedal 1 by hinge,
In the present embodiment, the bracket component is hinged by pedal 1 is two groups, both cost-effective, makes pedal 1 more stable again, frock ladder structure
More reliable.
Bracket component and pedal 1 is equipped with the fixed seat 4 and Mobile base 5, is made the use of frock ladder more flexible, is made
For a kind of preferred embodiment, fixed seat 4 is provided with pedal and two pack support components in the end away from Mobile base 5, Mobile base 5 away from
The end of fixed seat 4 also is provided with pedal and two pack support components, has maximally utilized space.
Positioning guide mechanism includes the groove 8 located at the projection 7 of 4 lower end of fixed seat and located at 5 upper end of Mobile base, raised 7
Coordinate with groove 8, raised 7 and groove 8 trend along Mobile base 5 moving direction, raised 7 located at the edge of fixed seat 4, recessed
Groove 8 is corresponding with raised 7 position;Locking mechanism includes that ratchet 9 and ratchet bar 10, ratchet bar 10 are located on 5 one side of Mobile base, spine
Pawl 9 is located at the end towards 5 moving direction of Mobile base of fixed seat 4.
Above-mentioned positioning guide mechanism causes Mobile base 5 along the movement of moving towards of the projection 7 of fixed seat 4, and due to projection 7
With the cooperation of groove 8 so that Mobile base 5 in moving process will not left and right play, make locking mechanism reliability service.
Ratchet 9 is fixed with handle 11, and handle 11 is connected with fixed seat 4 by axle 12, and handle 11 is rotated around axle 12, on axle 12
Torsion spring is arranged with, ratchet 9 is stuck in by torsion spring on the ratchet of ratchet bar 10, ratchet includes facing directly and inclined-plane 13, inclined-plane 13 and spine
The angle counterclockwise of the direction of advance of tooth bar 10 is acute angle, and ratchet 9 is kept being stuck on ratchet by above-mentioned locking mechanism by torsion spring,
As the angle counterclockwise of inclined-plane 13 and the direction of advance of ratchet bar 10 is acute angle, ratchet 9 only enters to the direction of retreat of Mobile base 5
Row locking, when Mobile base 5 advances, ratchet 9 will not be locked to the ratchet bar 10 on Mobile base 5, this work that the present embodiment is proposed
Dress ladder, analyzes its stress, and after workmen sets foot on pedal 1, Mobile base 5 is subject to the power for retreating which, so as to only need to lock
The direction of retreat of Mobile base 5.
Head rod 2 is fixed with supporting leg 14 away from one end of base, and supporting leg 14 is vertical with head rod 2, supporting leg 14
Away from one end hinged support seat 15 of head rod 2, support base 15 is hinged with supporting leg 14, and support base 15 can be around 14 turns of supporting leg
Dynamic, the corrugated bulkhead of different gradient is adapted to, supporting leg 14 makes to keep certain distance, convenient construction between corrugated bulkhead and pedal 1
Personnel construct.
Pedal 1 on each pack support component is at least three, and 1 spacing of adjacent pedal is identical, and the number of pedal 1 is regarded and needed
Want and select, it is ensured that easy construction.
Obviously, the above embodiment of the present invention illustrates example of the present invention just for the sake of clear, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
