The technical scheme of the invention is further explained by combining the accompanying drawings as follows:
FIG. 1 is a schematic view of a ladder caster bracket assembly of the present invention shown in use and disassembled without tools;
FIG. 2 is a right side view of the caster bracket apparatus of the present invention;
FIG. 3 is a top view of one embodiment of the caster bracket apparatus of the present invention;
FIG. 4 is a schematic view of the thrust member and disk member of the present invention in combination;
fig. 5 is a top view of another embodiment of the caster bracket apparatus of the present invention.
Detailed Description
The invention is described below with reference to the accompanying drawings.
As shown in fig. 1-5, the caster bracket device of the ladder of the invention, which can be assembled and disassembled without using tools, comprises a wheel carrier and a manual locking component; the wheel carrier comprises a roller part 1 and a ladder foot part 2, and the roller part 1 and the ladder foot part 2 are integrally formed by injection molding.
The roller part 1 is arranged on one side of the ladder foot part 2, the roller part 1 is used for installing the roller 3, an open part is arranged on one side of the ladder foot part 2, the ladder foot part 2 is inserted and sleeved on the ladder foot 4 through the open part, and symmetrical top plate hole grooves 5 are formed in side plates, located on two sides of the open part, of the ladder foot part 2.
In the actual use process, because the ladder foot 4 is usually in an inclined state, the ladder foot 2 and the roller part 1 need to be designed to be in a relatively inclined state, so that the plane where the ladder foot 2 is located and the roller shaft of the roller 3 form an included angle of 5-10 degrees, and the included angle is 7 degrees in the embodiment; when in use, the ladder foot 2 is matched with the inclined ladder foot 4, so that the wheel axle of the roller 3 on the roller part 1 can be kept horizontal.
The manual locking assembly comprises a top plate 6, a thrust part 7 and a friction part, two ends of the top plate 6 are respectively matched with top plate hole grooves 5 on two side plates of the ladder foot part 2, and the thrust part 7 is used for driving the friction part to press the ladder foot 4; in this embodiment, the pushing member 7 is a threaded rod with a knob, and a threaded hole is provided on the top plate 6 to be engaged therewith.
