Abstract

The invention provides a ladder of an improved structure. Through the ladder, the technical problems that an existing ladder is inconvenient to move, a ladder body cannot be located effectively during usage, and operation is inconvenient are solved. The ladder of the improved structure comprises a ladder body. The lower portion of the ladder body is provided with rolling wheels through connection structures. Each connection structure comprises an installation plate, a locating plate, a guide rod, a guide sleeve and a spring, wherein the installation plate is fixed to the lower portion of the ladder body, the guide rod is vertically fixed to the installation plate, the guide rod is slidably arranged on the guide rod, the spring is arranged on the guide rod in a penetrating mode, the upper end of the spring is connected with the installation plate, the lower end of the spring is connected with the guide sleeve, and the locating plate is fixed to the guide sleeve. The rolling wheels are fixed to the locating plate. The ladder body is further provided with a locating structure. The ladder has the advantage of convenient operation.

Description

technical field [0001] The present invention relates to a ladder of improved construction. Background technique [0002] Climbing the ladder, the slope is relatively steep, and people need to use both hands to escalate the stairs when going up and down. Generally, straight up and down ladders made of angle steel, welded pipes, iron chains or ropes are widely used in various industries. With the rapid development of economy and technology, climbing ladders are becoming more and more light, long service life, firm and safe. direction development. [0003] After retrieval, such as Chinese patent literature discloses a climbing ladder [application number: 201520975951.0; publication number: CN205153992U]. This climbing ladder is characterized in that it includes: a longitudinal bar; a plurality of transverse bars arranged along the longitudinal bar, and the transverse bar has a working position perpendicular to the longitudinal bar and a retracted position consistent with the ...
