Description

Safety insulation herringbone ladder

Technical Field

The utility model relates to the technical field of insulating herringbone ladders, in particular to a safe insulating herringbone ladder.

Background

Herringbone ladder: the ladder is also called a folding ladder and is used for a type of ascending tool working in a space above a plane, the application is wider, and the herringbone ladder made of insulating materials is called an insulating herringbone ladder;

the insulating double ladder and the common double ladder are identical in structure, the double ladder is composed of two double ladders with hinged upper ends, limiting pull tabs are hinged between the two double ladders, so that the double ladder can keep a certain opening and closing angle when in use, a user can ascend on the double ladder to operate in a high-altitude mode, particularly the double ladder is higher, when the worker shakes in high-altitude operation, the double ladder is easy to topple towards two sides under the auxiliary condition of no related person, certain potential safety hazards exist, and therefore, in order to improve the safety of the double ladder, extension plates are arranged on two sides of the lower ends of the double ladders, so that the double ladder is not easy to topple towards two sides, but only a single extension plate is arranged, the stability of the double ladder is to be improved, and meanwhile, the extension plates are welded or are fixedly connected through screws, cannot be folded and folded to be placed, the occupied space is large, and the double ladder can be placed in a relatively troublesome manner.

Disclosure of Invention

The utility model aims to overcome the technical defects, and provides the safe insulating herringbone ladder, which is further improved in placement safety, is not easy to topple over to two sides, and can be conveniently folded and unfolded while reducing occupied space.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a safe insulating double ladder, includes insulating double ladder body, insulating double ladder body includes the cat ladder that the upper end is articulated together, both sides all articulate between the both sides of cat ladder has one end to articulate the connection spacing piece together, lower part one side of two pole settings of cat ladder all is equipped with receives and releases groove one, receive and releases groove one interior articulated extension board that has, be equipped with receive and release groove two on the extension board, receive and release inslot and articulate there is the diagonal bracing pole in groove two, receive and release inslot be equipped with diagonal bracing pole complex slot.

Compared with the prior art, the utility model has the advantages that: when the telescopic support is used, the extension support plate is rotated out of the first retraction groove and is in contact with the ground, then the inclined support rod in the second retraction groove is rotated out, and one end of the inclined support rod is inserted into the slot, so that a triangular stable support structure is formed among the extension support plate, the inclined support rod and one upright rod of the ladder, the placement safety of the telescopic support plate is further improved, meanwhile, when the telescopic support plate is not used, the inclined support rod is retracted, then the extension support plate is retracted, and the telescopic support plate can be conveniently retracted and released while the occupied space can be reduced.

As an improvement, the rubber anti-slip pad is glued on one side of the extension support plate, which is opposite to the second retraction slot, so that the placement stability of the herringbone ladder is further improved.

As an improvement, both sides of the cat ladder are hinged with baffle plates matched with the extension support plates, so that the extension support plates are prevented from automatically rotating out of the first winding and unwinding grooves.

As an improvement, the lower end of the first receiving and releasing groove is in an opening state, and the extension support plate is hinged at the opening of the lower end of the first receiving and releasing groove, so that the design is reasonable, the extension support plate can be enabled to tend to be in horizontal contact with the ground, and the placement stability is further improved.

Drawings

Fig. 1 is a front view of a safety insulating herringbone ladder of the present utility model.

Fig. 2 is a left side view of a safety insulating herringbone ladder of the present utility model.

As shown in the figure: 1. an insulating herringbone ladder body; 2. a ladder stand; 3. connecting a limiting piece; 4. a baffle; 5. a first winding and unwinding groove; 6. a slot; 7. a diagonal support bar; 8. a second winding and unwinding groove; 9. a rubber anti-slip pad; 10. and the support plate is prolonged.

Detailed Description

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

The safe insulating double ladder comprises an insulating double ladder body 1, wherein the insulating double ladder body 1 comprises a ladder stand 2 with upper ends hinged together, and connecting limiting pieces 3 with one ends hinged together are hinged between two sides of the ladder stand 2;

the lower part one side of two pole settings of cat ladder 2 all is equipped with receive and release groove one 5, receive and release inslot articulates there is extension supporting plate 10, receive and release groove one 5's lower extreme is the open state, extension supporting plate 10 articulates in receive and release groove one 5's lower extreme opening part, the both sides of cat ladder 2 all articulate have with extension supporting plate 10 complex baffle 4, be equipped with receive and release groove two 8 on the extension supporting plate 10, receive and release inslot 8 articulates there is diagonal bracing bar 7, extension supporting plate 10 and receive and release groove two 8 relative one side gluing have rubber slipmat 9, receive and release inslot 5 in be equipped with diagonal bracing bar 7 complex slot 6.

When the utility model is in practical implementation, the two side ladders rotate to two sides during use and are limited by connecting the limiting sheets, as shown in the attached figure 1 of the specification, the opening mode is the same as that of the traditional herringbone ladder;
