Description
Technical field
This utility model belongs to an accessory technical field, especially relates to a kind of basket cot self-locking universal wheel.
Background technology
In order to improve the convenience of nursing, particularly sick bed.
At present, existing sick bed its all have bed wheel locking function.Locking carries out locking by brake block and controls.
Current locking mode generally steps on the mode of foot, then forces brake block to contact with bed wheel, i.e. to realize locking.But, existing
Locking mode its exist brake poor stability technical problem.
Such as, Chinese patent literature disclose a kind of sick bed caster brake system [application number: 200420115393.2:,
Be connected on base brake pipe, and the foot-operated and same axle center of brake pipe is fixed together, and brake pipe has welded two round steel, described
Round steel is fixed together through the elongated hole on drive block, drive block and brake hexagonal steel, and brake hexagonal steel passes in middle control castor
The inner hexagonal hole of cam, cam just can be followed brake hexagonal steel and be rotated together, and under brake releasing orientation, brake nut leads to
Crossing round pin to withstand in this groove, brake lever moves up, and brake lever end portion and brake member are separated；Under braking state,
Cam rotates counterclockwise, and round pin, under the effect of cam, promotes brake nut and brake lever to move down, the bottom of brake lever
Divide and brake member matches, the brake hub on brake member contact castor.
Although above-mentioned scheme has above plurality of advantages, but, above-mentioned scheme the most thoroughly solves above-mentioned skill
Art problem, or there is the defect of brake poor stability.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of design is more rationally and the more stable basket cot that brakes
Self-locking universal wheel.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this basket cot self-locking universal wheel includes wheel
Body, connects on wheel body and has bracing frame, be provided with the limited block being positioned at outside wheel body on bracing frame, hinged on described bracing frame
Having pedal, connecting on pedal has the arc brake sheet being articulated and connected with pedal, in arc brake sheet lower surface one end
Be provided with when stepping on described pedal described arc brake sheet can be forced to deform upon and contact with wheel body circumference
Support bulge-structure, and the front end of arc brake sheet is positioned at below described limited block, and to be prevented from described arc brake sheet excessive
Deform upon.
Owing to being provided with support protrusion structure, limited block and the structure of arc brake sheet, further increase use can
By property, design more hommization and braking is more reliable and more stable.
In above-mentioned basket cot self-locking universal wheel, described support protrusion structure includes being fixed on arc brake sheet following table
The V-arrangement of one end, face is protruding.
In above-mentioned basket cot self-locking universal wheel, it is provided with in described V-arrangement projection and is connected with arc brake sheet lower surface
Stirrup.
In above-mentioned basket cot self-locking universal wheel, described limited block lower surface is provided with some toothed projections.
In above-mentioned basket cot self-locking universal wheel, described bracing frame is provided with connecting stud.
In above-mentioned basket cot self-locking universal wheel, described pedal is hinged on the middle part of arc brake sheet.
In above-mentioned basket cot self-locking universal wheel, described wheel body is quiet wheel.
Compared with prior art, the advantage of this basket cot self-locking universal wheel is: 1, owing to being provided with support protrusion knot
Structure, limited block and the structure of arc brake sheet, further increase the reliability of use, designs more hommization and brakes more
Reliable and stable.2, simple in construction and low cost of manufacture.3, service life is long.4, quiet wear-resisting, turn to flexibly, ruggedness is strong, peace
Fill and change very convenient.
