Abstract

The utility model relates to a door type scaffold whose technical characteristic is in comprising adjustment levers, portal frames, latch pins, intersecting draw poles and connective bars. Two adjacent portal frames are connected with each other by the intersecting draw pole; the connective bars are inserted on the portal frame by the latch pin; the upright pole of the latch pin is provided with twelve latch pins which are used to fix the intersecting draw pole. The distribution regularity of the latch pins is that both ends of the upright poles of the portal frames are respectively provided with three latch pins. The distribution regularity of the three latch pins which are arranged on both ends of the upright poles of the portal frames is that the distance between the first lock pin and the second lock pin from the end is equivalent to half of the distance between the second and the third lock pins. As both ends of the upright pole of the portal frame are provided with three pairs of lock pins respectively, the adjustment range of the intersecting draw poles are increased, the interchangeability of the portal frames is improved, and the installation of the scaffold is more convenient.

Description

A kind of door-type scaffold

Technical field

The utility model relates to a kind of scaffold.

Background technology

Relevant by retrieval patent documentation does not retrieve the door-type scaffold identical with the utility model structure at present as yet.The kind of existing scaffold is more, differs from one another.Its basic skills is generally and adopts intertie that door frame is fixed, and reaches firm purpose.But because its structural reason, the spacing between adjacent two door frames still is subjected to certain restriction, thus be necessary existing scaffold is improved, to satisfy actual requirement.

Summary of the invention

The purpose of this utility model is that a kind of improvement on existing door-type scaffold will be provided, and has the bigger a kind of door-type scaffold of adjustable range.

Technical characterictic of the present utility model is: considering to add on the basis of wide adjusting range, raising lifting capacity, be designed to by a kind of door-type scaffold that comprises adjusting rod, door frame, latch, intertie, pitman, intertie links to each other adjacent two door frames solid, pitman is inserted on the door frame by latch, be fixed with 12 fixedly lock pins of intertie in the vertical rod of described door frame, the regularity of distribution of lock pin is that two vertical rod two ends of door frame are provided with three respectively.

Three lock pins that the vertical rod two ends of described door frame are provided with respectively, its distribution mode is: with the end be spacing between first lock pin of starting point and second lock pin be between second lock pin and the 3rd lock pin spacing 1/2.

During use, by intertie adjacent two door frames are connected, three lock pins that two vertical rod two ends of door frame are provided with respectively its objective is that the distance of being convenient to adjust between the door frame designs.

The utility model has the advantages that: because the two ends of door frame upper pright stanchion are respectively equipped with three pairs of lock pins, thereby increased the adjustable range of intertie, improved the interchangeability of door frame, made installation more convenient; Because rational in infrastructure, adjustable range is big, so very big practical and popularizing value is arranged.

Description of drawings

Accompanying drawing is the structural representation of a kind of door-type scaffold of the utility model.

The specific embodiment

With reference to accompanying drawing, the utility model is made up of adjusting rod 1, door frame 2, latch 3, intertie 4, pitman 5, intertie 4 links to each other adjacent two door frames 2 solid, pitman 5 is inserted on the door frame 2 by latch 3, be fixed with 12 fixedly lock pins 6 of intertie 4 in the vertical rod of door frame 2, the regularity of distribution of lock pin 6 is that two vertical rod two ends of door frame 2 are provided with three respectively, and its distribution mode is: with the end be spacing between first lock pin of starting point and second lock pin be between second lock pin and the 3rd lock pin spacing 1/2.
