Abstract
The utility model relates to a folding step ladder, which includes front support legs, rear support legs, pedals and a support plate, wherein the pedals are fixed on the front support legs; the upper ends of the rear support legs are rotationally matched with the front support legs; a horizontal tube is further arranged on the rear support legs; one end of the support plate is rotationally connected with the front support legs, and the other end of the support plate is overlapped on the horizontal tube of the rear support legs; a locking buckle connected with the horizontal tube is arranged at the other end of the support plate; a connecting rod is arranged at the bottom of the support plate; the two ends of the connecting rod are rotationally matched with the support plate and the horizontal tube respectively. When the front support legs and the rear support legs of the folding step ladder are separated into a herringbone structure, the other end of the support plate is overlapped with the horizontal tube of the rear support legs, the support plate is downwards pressed with force, a locking hook of the locking buckle hooks the horizontal tube to lock the horizontal tube, and the step ladder is prevented from automatically folding during the use, so that the folding step ladder is safe and reliable.
Description
Technical field
The utility model relates to pedal ladder, particularly a kind of folding step ladder.
Background technology
China Patent No. CN00814270.X discloses a kind of step stool on August 11st, 2000, comprises that one contains a foreleg and a foldable framework with respect to the movable back leg of foreleg, and one is supported in the portable handle that certain leg rotates around pivotal axis.One retainer is connected with handle and moves around pivotal axis together with handle, and foreleg is locked on back leg.The step stool complex structure of this structure, uses inconvenience, remains to be further improved.
Utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and a kind of folding step ladder simple and reasonable for structure, esy to use, safe and reliable is provided.
The purpose of this utility model is to realize like this.
A kind of folding step ladder, comprise front leg strut, rear support leg, pedal and gripper shoe, pedal is fixedly installed on front leg strut, rear support leg upper end and front leg strut are rotatably assorted, and are also provided with transverse tube on rear support leg, and gripper shoe one end and front leg strut are rotationally connected, the gripper shoe other end is overlapped on the transverse tube of rear support leg, it is characterized in that: the other end of described gripper shoe is provided with the tab for joining with transverse tube, gripper shoe bottom is provided with connecting rod, and connecting rod two ends are rotatably assorted with gripper shoe and transverse tube respectively.
The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, described tab one end and gripper shoe are hinged, and the other end is provided with lock hook, and lock hook outside is provided with spanner, between tab and gripper shoe, is provided with reduction torsion spring.
The corresponding transverse tube of described connecting rod is provided with bell and spigot joint, and bell and spigot joint is set in outside transverse tube.
Described rear support leg upper end is rotationally connected by hinge and front leg strut, and rear support leg and front leg strut lower end are respectively equipped with rear non-slip feet and front non-slip feet.
Described front leg strut upper end is protruding and join with glove top board.
Described glove top board surface is provided with article putting groove, hook, large jack and/or little jack.Article putting groove can be used for placing the small parts such as screw, and hook is used for hanging up object, and large jack is used for inserting the objects such as hammer, and little jack is used for inserting the objects such as screwdriver.
The beneficial effects of the utility model are as follows.
When the front leg strut of this kind of folding step ladder and rear support leg are separated into herringbone, the other end of gripper shoe is overlapped on the transverse tube of rear support leg, firmly presses down gripper shoe, the lock hook of tab fastens transverse tube, form locking, avoid pedal ladder in use folding voluntarily, it is safe and reliable.When needs Foldable pedal when ladder, the spanner position of pulling tab, rotates tab, and lock hook departs from transverse tube, in released state, mentions gripper shoe simultaneously, can by front leg strut and rear support leg is folding closes up, and it is easy to operate.
