Further, it is surveyed in left ladder, right ladder and is provided with connection ear, left ladder, the connection ear of right ladder are hinged.

Further, the second rocking bar lower end is hinged by hinge and the first rocking bar, and intermediate connecting rod upper end passes through hinge and the It is hinged in the middle part of two rocking bars.

Further, one, the telescopic end and support rod of a word pull rod is made in the fixing end of a word pull rod and the first rocking bar One is made.

Further, the word pull rod is ten grade of one word pull rod.

Further, the long length for being less than left ladder, right ladder of support rod.

Compared with prior art, it the utility model has the following beneficial effects: structure is simple, can make one to stand directly on ladder On ladder moved by control double rocking lever, centre-of gravity shift, and in the process of moving, remain that center is supported at two Between point, the balance of ladder is kept, is not tumbled, ensure that safety, it is easy to use, it improves work efficiency.

Detailed description of the invention

The utility model patent is further illustrated with reference to the accompanying drawing.

In figure:

The left ladder bars of 1-, 2- multistage adjust self-locking mechanism, the first rocking bar of 3-, the second rocking bar of 4-, 5- intermediate connecting rod, the right ladder of 6- Frame, 7- support rod.

Specific embodiment

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in Figs. 1-2, a kind of mechanical movable fall ladder, including left ladder, right ladder, the first rocking bar, the second rocking bar, Intermediate connecting rod, support rod, the left ladder, right ladder upper end are hinged, pass through compound hinges and left ladder, the right side in the middle part of the first rocking bar Ladder is connected, and the second rocking bar is located at left ladder, right ladder top, and the second rocking bar lower end and the first rocking bar are hinged, under the first rocking bar Portion is provided with a word pull rod, and the fixing end of word pull rod is fixedly mounted on the first rocking bar, the telescopic end and support rod of a word pull rod Upper end is fixedly connected, and the telescopic end of a word pull rod and intermediate connecting rod lower end are hinged.

In the present embodiment, it is surveyed in left ladder, right ladder and is provided with connection ear, the connection ear of left ladder, right ladder Hingedly.

In the present embodiment, the second rocking bar lower end is hinged by hinge and the first rocking bar, and intermediate connecting rod upper end passes through hinge It is hinged with the second rocking bar middle part.

In the present embodiment, one, the telescopic end and branch of a word pull rod is made in the fixing end of a word pull rod and the first rocking bar One is made in strut.

In the present embodiment, the word pull rod is ten grade of one word pull rod.

In the present embodiment, the long length for being less than left ladder, right ladder of support rod.

In the present embodiment, a word pull rod common component known to those skilled in the art, a word pull rod are general For massage bed, medical bed, drawing table, the adjusting of the backrest angles such as desk.Of course for improve the straight of prismatic pair during exercise Dimension and the rigidity for improving a word pull rod, the fixing end of a word pull rod are seated two sides and are provided with sliding slot, and setting is slided in sliding slot Block, upper end of slide block are located in sliding slot, and the sliding block lower end of two sides is connected through connecting rod, in the middle part of the connecting rod and extension end of a word pull rod Hingedly, the sliding block of two sides and connecting rod, which are made, is integrally formed a U-shaped part.

In use, left ladder lower end (A point), right ladder lower end (C point) prop up as shown in figure 3, left ladder, right ladder is unfolded Support in ground, user climb up the ladder top, the center of gravity of user is in the middle of ladder at this time；User swings to the right One rocking bar, while the second rocking bar is depressed, by intermediate connecting rod, drives the telescopic end of a word pull rod to move down, make a word pull rod Bottom gear realize it is self-locking, support rod move down and with ground face contact (B point), complete the first step operation double rocking lever movement； User's center of gravity moves right, and support rod lower end (B point) and right ladder lower end (C point) is used as supporting point, is supported in ground, passes through Leg power lifts left ladder slightly, completes expansion one side ladder movement；User's center of gravity is turned left offset, left ladder lower end (A ' Point), support rod lower end (B point) as supporting point contact ground, right ladder lower end leaves ground, and right ladder is moved to the left by gravity Until right ladder lower end (C ' point) contacts ground as supporting point, centre-of gravity shift movement, final left ladder lower end, right ladder are completed Lower end is supported in ground, and ladder is displaced to the left；User depresses the second rocking bar, by intermediate connecting rod, a word is driven to draw The telescopic end of bar continues to move down, and when telescopic end is moved to bottom, self-locking state is released, and user is by lifting second Rocking bar drives the telescopic end of a word pull rod to move up, so that support rod is left ground, at this time the first rocking bar by intermediate connecting rod It can freely swing, be ready for next period of motion.

Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage, It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical Within novel protection scope.
