Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): as shown in fig. 1, for the utility model discloses a cat ladder with adjustable, including base 10 (prior art), a plurality of running-board 1 that is parallel to each other is installed to the top of base 10, interconnects through adjusting part 2 between per two running-board 1, and adjusting part 2 can adjust the interval between two running-board 1. The top end of the ladder stand is connected with a lifting hook 3 used for hooking a building, when the ladder stand is used, the base 10 is placed on one side of the building, the ladder stand is adjusted to a proper height by the adjusting component 2, so that the lifting hook 3 lifts the top end of the building, and the ladder stand can adapt to wall surfaces with different heights to carry out construction operation.

As shown in fig. 2, the adjusting assembly 2 includes a mounting frame 4 for fixing the pedal 1, a bump 12 is inserted into the mounting frame 4, the bump 12 is respectively installed at two ends of each pedal 1 through bolts, when the pedal 1 needs to be installed, the bump 12 is inserted into the mounting frame 4 first, and then the pedal 1 is installed, so that the pedal 1 can be detached from the ladder.

As shown in fig. 2, the adjusting assembly 2 includes a mounting block 41 fixed on the outer wall of the mounting frame 4, a first hinge rod 5 is rotatably connected to the mounting block 41, one end of the first hinge rod 5 away from the mounting block 41 is rotatably connected to a second hinge rod 6, and a hinge point of the first hinge rod 5 and the second hinge rod 6 is a first hinge point 7. One end of the second hinge rod 6, which is far away from the first hinge rod 5, is rotatably connected with the outer wall of the other adjacent mounting frame 4, and a locking assembly 8 capable of fixing a pair of adjacent pedals 1 to each other is mounted on the side wall of each pedal 1.

As shown in fig. 3 and 4, when the length of the ladder needs to be shortened, a pair of adjacent pedals 1 are moved closer to each other to cause a pair of first hinge points 7 to be respectively moved closer to each other, the first hinge points 7 are moved closer to the pair of pedals 1, the first hinge rod 5 and the second hinge rod 6 are gradually rotated in the horizontal direction from the vertical direction, and when the first hinge rod 5 and the second hinge rod 6 are respectively abutted against the pedals 1 on both sides, the distance between the two pedals 1 is the closest, and the locking assembly 8 is used to lock the pair of pedals 1 which are moved closer to each other to shorten the length of the ladder, thereby being capable of adapting to operations with different heights.

As shown in fig. 5 and 6, a receiving groove 11 is formed in one side of the pedal 1 close to the second hinge rod 6, and the receiving groove 11 is used for receiving the first hinge rod 5 and the second hinge rod 6 which are rotated to the horizontal position, so that the pedal 1 can be placed more stably and safely when being rotated to the horizontal position. One side of installing second hinge bar 6 of installing frame 4 is equipped with mounting groove 42, and the one end rotation connection that first hinge bar 5 was kept away from to second hinge bar 6 is in mounting groove 42, and mounting groove 42 communicates with each other with holding groove 11, and second hinge bar 6 supports the inner wall of holding groove 11 when rotating horizontal position. When a pair of pedals 1 are close to each other, the mounting block 41 is placed in the mounting groove 42, and one side of the first hinge lever 5 abuts against the inner wall of the housing groove 11 and the other side abuts against the side of the pedal 1 on which the first hinge lever 5 is mounted. The first hinge rod 5 and the second hinge rod 6 are both rotatable and accommodated in the accommodating groove 11, so that the adjacent sides of the pair of adjacent steps 1 can be closely attached to each other, and the structure of the shortened ladder stand is more stable when the ladder stand is placed for use.

As shown in fig. 3 and 4, the locking assembly 8 includes a rotating rod 81 rotatably connected to the side wall of the pedal plate 1, a rubber block 82 fixedly connected to one end of the rotating rod 81 far away from the fixing block, an insertion block 83 disposed on the side of the same side of the pedal plate 1 adjacent to the fixing block, and an insertion groove 831 disposed on the side of the insertion block 83. When a pair of running-boards 1 is close to each other, rotate dwang 81, make dwang 81 rotate, the one end of dwang 81 leans on inserting groove 831 gradually, and rubber block 82 pegs graft in inserting groove 831 and receives the extrusion of inserting groove 831, and rubber block 82 can be more stable fix in inserting groove 831.

As shown in fig. 2, a non-slip mat 9 is further installed on one side surface of the step plate 1 for stepping, and when a worker climbs, the worker steps on the non-slip mat 9, so that the work can be more safely climbed.

The implementation principle of the embodiment is as follows: when the ladder stand is heavy and a worker cannot carry the ladder stand, the pedal 1 can be pulled out of the mounting frame 4, the weight of the ladder stand is reduced, the ladder stand is carried to a specified place, then the pedal 1 is carried, and the pedal 1 is mounted in the mounting frame 4.

After the ladder stand is carried to a specified place, the lifting hook 3 is hung on a building, one end of the ladder stand is fixed through the lifting hook 3, then the length of the ladder stand is adjusted, the first hinge rod 5 and the second hinge rod 6 are rotated to be adjusted, the pair of first hinge points 7 between the pair of pedals 1 are mutually close, the first hinge rod 5 and the second hinge rod 6 are rotated to mutually close the pair of pedals 1, and the locking assembly 8 is used for fixing the pair of pedals 1, so that the length of the ladder stand can be shortened.

The distance between the pair of pedals 1 can be increased by increasing the included angle between the first hinge rod 5 and the second hinge rod 6 when the pair of hinge points are far away from each other, so that the length of the whole ladder stand is increased, and the height of a building which can be operated is adapted.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
