[utility model content]

The purpose of this utility model is to solve above-mentioned the problems of the prior art, it is provided that a kind of Multifunctional anti-drop is made Industry ladder.

To achieve these goals, this utility model is achieved by the following technical solutions:

A kind of Multifunctional anti-drop operating ladder, including framework, backrest and connection framework and the safety rope of backrest；Frame Offering spherical groove on the dual-side of frame, the length of spherical groove is identical with the height of framework；The bottom of backrest is hinged Having two ends is the connecting rod of ball-type, and the end of connecting rod is arranged in spherical groove；Connecting rod can be spherical , the top of backrest arranges at least one handle in groove 1 slidably, and the two ends of safety rope are provided with hook, One end is connected on handle, and the other end is connected on the cross bar of operating ladder.

This utility model is further improved by:

Two handles it are provided with on described framework.

The bottom of described framework connects the support member for fitting with ground.

Also including two frameworks being hinged at, two frameworks can launch by pin joint laterally, is arranged side by side.

Compared with prior art, this utility model has the advantages that

This utility model arranges backrest on operating ladder, and is fixed by safety rope, can regulate simultaneously and lean on The height of the back of the body and angle, make gravity center of human body be adjusted, the safest, is rolled over by upper and lower two-layer The design of stack structure, ladder can carry out many people and work simultaneously, improves work efficiency.

[detailed description of the invention]

Below in conjunction with the accompanying drawings this utility model is described in further detail:

Seeing Fig. 1, this utility model includes framework 4, backrest 3 and connects framework 4 and the safety of backrest 3 Rope；Offering spherical groove 1 on the dual-side of framework 4, the length of spherical groove 1 is identical with the height of framework 4； The bottom of framework 4 connects the support member 6 for fitting with ground.The bottom of backrest 3 is hinged with two ends For the connecting rod 2 of ball-type, the end of connecting rod 2 is arranged in spherical groove 1；Connecting rod 2 can be at spherical groove In 1 slidably, the top of backrest 3 arranges two handles 5, and the two ends of safety rope are provided with hook, and one End is connected on handle 5, and the other end is connected on the cross bar of operating ladder.

It addition, this utility model can be by hinged for two frame facets, two frameworks can laterally hinged Point launches, and is arranged side by side.

Structural principle of the present utility model:

As shown in Figure 4, this utility model ladder two body side frame offers spherical groove, and soccer star's slot fit end is ball-type Connecting rod so that backrest can on ladder slidably, and adjustable angle.

As it is shown in figure 5, be connected by pin mode between backrest with connecting rod so that backrest can be top at human body Time, can on the basis of connecting rod Secondary Control angle, more preferable center-of-gravity regulating.

As shown in Figure 6, ladder base is provided with the support member being connected with ladder pin so that the most arbitrarily angled work When making, ladder can obtain a maximal friction, prevents the level of ladder from sliding.

As it is shown in fig. 7, the two-layer up and down of ladder is connected by pin mode, reach the function of folding and expanding with this.

As shown in Figure 8, backrest top is provided with two handles, and safety rope operationally can be utilized to enter with ladder Row connects.

Operation principle of the present utility model:

The fluting design on ladder both sides, it is upper and lower that the design of collocation sliding bar makes backrest be free to along ladder Mobile, there is again pin to be connected between sliding bar with backrest so that the freely adjustable angle of backrest.Ladder is divided into two-layer Design, upper and lower two-layer carries out foldover design so that need many man-hours, can carry out many people work simultaneously after expansion Make.The top dress house of backrest has two handles, utilizes the safety rope one end with hook arriving suitable position Clasping handle, after regulation, one end is buckled on ladder whippletree, reaches fixing shatter-resistant effect with this.

As it is shown in figure 9, when one-man job, the upper and lower two-layer of ladder is in folded state, staff is being carried out During ascending stair, backrest lies against ground, and upper strata ladder portion support member is opened, and safety rope hanger one end is buckled in backrest On handle.

As shown in Figure 10, staff after climbing up ladder, health one end rope safe to carry other end, with The rising of staff, backrest rises the most immediately, after arriving correct position, and the length of regulation safety rope, The i.e. suitable angle of adjustable so that the center of gravity of personnel is adjusted.

As shown in figure 11, work that a people cannot complete can be run into during work or need assistant to help, and one There is no again sufficient space two people that stand on individual ladder when working simultaneously, carry out being expanded to proper angle by ladder, Open support member, can carry out double working simultaneously, people's auxiliary, one man operation.If paraprofessional personnel needs During long-time operation, the framework of lower floor's ladder is also configured with sliding tray, backrest integration member is installed up on groove I.e. can reach the function identical with main ladder.

Above content only illustrates technological thought of the present utility model, it is impossible to limit protection of the present utility model with this Scope, every according to the technological thought that the utility model proposes, any change done on the basis of technical scheme, Within each falling within the protection domain of this utility model claims.
