Description
Technical field
The utility model relates to a kind of arrestment mechanism that can arbitrarily move the ladder of ascending a height.
Background technology
Existing ladder does not all have movable mechanism, all needs us to carry or is lifting and arriving required place, and the ladder that has is generally all long, heavier, needs many people to help and just can carry out, and has influenced our operating efficiency greatly, makes troubles to our work, life.
The utility model content
In order to solve the problems referred to above that prior art exists, the utility model proposes the ascend a height arrestment mechanism of ladder of a kind of movable type, it is simple in structure, can random mobile ladder, bring convenience to us.
The utility model can be solved by the following technical programs:
A kind of movable type ascend a height the ladder arrestment mechanism, comprising:
One fulcrum structure, comprise a pedal, a resetting means, back-up block, this pedal axially flexibly connects by first main shaft and described bottom platform of ascending a height ladder, and this resetting means is connected with the described terraced bottom platform of ascending a height by a spring, and this back-up block is connected with the described first main shaft lower position;
One lever construction, comprise a treadle, the main support that is connected respectively with the treadle two ends, this main support axially flexibly connects by second main shaft and described bottom platform of ascending a height ladder respectively, and be respectively equipped with block structure and support platform on this main support, the below of the main support that is connected respectively with described treadle two ends is a fixedly connected universal wheel respectively;
Above-described back-up block can be supported on the described support platform.
Block structure described in the utility model and spring are located at the place, the same side of described support platform.
Universal wheel described in the utility model is located at the lower position of described block structure and support platform.
The arrestment mechanism of ladder because the above technical scheme of employing, a kind of movable type of the present utility model are ascended a height, it is simple in structure, the cooperation of adopting fulcrum structure and lever construction just can random mobile ladder, and need not spend our how much strength, also saved manpower, to we work, the life offer convenience.

Fig. 4 is a kind of movable type of the utility model structural representation of lever construction in the arrestment mechanism of ladder of ascending a height
Among the figure 1 ascend a height the ladder bottom platform; 2 pedals; 3 springs; 4 first main shafts; 5 back-up blocks; 6 treadles; 7 main supports; 8 second main shafts; 9 block structures; 10 support platforms; 11 universal wheels
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model:
Shown in Fig. 1,2,3,4, a kind of movable type ascend a height the ladder arrestment mechanism, comprise: a fulcrum structure, it comprises a pedal 2, a resetting means, back-up block 5, this pedal 2 axially flexibly connects by the bottom platform 1 of first main shaft 4 with the ladder of ascending a height, this resetting means is connected by the bottom platform 1 of a spring 3 with the ladder of ascending a height, and this back-up block 5 is connected with first main shaft, 4 lower positions; One lever construction, it comprises a treadle 6, the main support 7 that is connected respectively with treadle 6 two ends, this main support 7 axially flexibly connects by the bottom platform 1 of second main shaft 8 with the ladder of ascending a height respectively, and be respectively equipped with block structure 9 and support platform 10 on this main support 7, the below of the main support 7 that is connected respectively with treadle 6 two ends is a fixedly connected universal wheel 11 respectively, and universal wheel 11 is located at the lower position of block structure 9 and support platform 10; Back-up block 5 can be supported on the support platform 10; Block structure 9 and spring 3 are located at the place, the same side of support platform 10.
As shown in Figure 1, structural representation during for the utility model mobile status, when the needs ramp period of the day from 11 p.m. to 1 a.m, can trample the treadle 6 of lever construction, at this moment lever construction moves down, universal wheel 11 lands, the support platform 10 of lever construction moves down, fulcrum structure unclamps pin this moment because the pulling force of back-moving spring 3 to the rotation of block structure 9 directions, is run into block structure 9 up to back-up block 5, back-up block 5 move down with support platform 10 near, back-up block 5 is propped up lever construction, because the pulling force of spring 3, fulcrum structure can not reset.
As shown in Figure 2, structural representation during for the utility model inactive state, when needs use ladder, can trample the pedal 2 of fulcrum structure, fulcrum structure is rotated counterclockwise, back-up block 5 breaks away from support platform 10, because the gravity of ladder itself, universal wheel 11 is moved upward by the reaction force of terraced body gravity, drives whole lever construction and moves upward, this moment, the feet of ladder landed, and made ladder be in static serviceable condition.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
