Description
Technical field
The present invention relates to metallic article technical field, specifically refers to a kind of flexible armrest for trolley.
Background technology
The places such as the extensive construction site of hand steered trolley, it not only can transport the solid materials such as brick, sand, stone, it is also possible to transport
The pureed material such as defeated concrete, can also transport the fluent materials such as water, and due to its simple structure, transporting capacity is strong, extensively by workman
Welcome.
But, its real transport section only struggles against, aid when its handrail is simply carried out manually, the length of handrail
Degree is but the half of whole trolley length, and this occupies big quantity space when trolley need not use handrail, is unfavorable for that trolley is filled
The transport of full goods.And trolley, when cargo transport is filled, using elevator traffic, to load whole trolley, elevator length is necessary
More than trolley length so that elevator design space is big, and material is more, high cost.
The content of the invention
It is an object of the invention to provide a kind of flexible armrest for trolley, the handrail makes trolley overall length adjustable, not
On the premise of changing former performance, trolley is used in small space, be conducive to trolley in the transport of small space
Work.
The present invention is achieved through the following technical solutions：
A kind of flexible armrest for trolley, includes first crossbeam and second cross beam, one end connection of first crossbeam the
One end of two crossbeams, the other end of second cross beam is connected with handrail, and first crossbeam, second cross beam and handrail are cylinder, and
First crossbeam axis, second cross beam axis and handrail axis collinear；Second cross beam is provided with the axial direction cylindrical beam and leads to
Hole, crossbeam through hole outside is symmetrically arranged with gathering sill and draw-in groove；Handrail one end is provided with guide pad and card column through hole, and guide pad is solid
Dingan County is mounted on handrail, and card column is provided with card column through hole, and handrail is provided with the axial direction cylindrical handle through hole, and handrail leads to
Hole has been disposed radially mounting groove, and fixed plate is provided with mounting groove, and fixed plate middle part is provided with fixed plate through hole, and fixed plate is led to
Control-rod is installed, control-rod one end connection card column, the control-rod other end is connected with flexible knob, and flexible knob is arranged in hole
On handrail.
First crossbeam and second cross beam are fixedly mounted on trolley, and guide pad is arranged in gathering sill, guide pad and guiding
The width of groove is identical, prevents guide pad from rotating, it is impossible to move radially, and is merely able in gathering sill along the axial direction of second cross beam
Slide；Card column is arranged in card column through hole, and card column can be moved along card column through hole, when card column is entirely located in card column through hole,
Handrail can be axially moveable in second cross beam, and when card column is not entirely located in card column through hole, card column part is located in draw-in groove
When, draw-in groove limits card column motion, and then limits handrail movement, plays fixation；Control-rod is arranged in fixed plate through hole, Gu
Fixed board through hole limits the radial motion of control-rod, and control-rod can be axially moveable and rotate.
When needing that handrail is retracted, rotary extension knob drives control-rod to rotate and be axially moveable, and control-rod drives
Card column is inside contracted, and when card column is entirely located in the card column through hole of handrail, promotes handrail, handrail to be axially moveable, and makes one, handrail
In dividing retraction second cross beam；When needing to stretch out on handrail, handrail is pulled out, until card column is located at groove position, card column
Card column through hole is stretched out, a card column part is located in draw-in groove, draw-in groove is identical with card column size, draw-in groove limits card column and handrail fortune
It is dynamic, now, there is active force to act on handrail, the active force is transferred directly on trolley.The handrail makes trolley overall length adjustable,
On the premise of not changing former performance, trolley is used in small space, be conducive to trolley in the fortune of small space
Defeated work.
Further, swing in second cross beam to limit handrail, while meeting movement of the handrail in second cross beam
Demand, the diameter of the crossbeam through hole being arranged on second cross beam is identical with the diameter of handrail.
Further, the flexible knob is threaded connection with control-rod.The screw thread of flexible knob and the spiral shell of control-rod
Line is mutually perpendicular to so that flexible knob drives when rotated control-rod to rotate and drives control-rod to be axially moveable.
Further, the card column is provided with spring with the junction of the card column through hole of handrail.Card column is made without external force
When can with auto-extending card column through hole reach draw-in groove in, make card column realize automatic locking in fixed position.
Further, the card column is connected with control-rod by cotton thread, and reinforcement is provided with cotton thread.When control-rod rotation
When, cotton thread is wrapped on control-rod, pulls card column to retract, meanwhile, control-rod is moved along axis, further pulls on card column retraction,
Under the double action for rotating and moving so that card column can be fully retracted in card column through hole.
Further, to enable card column more flexibly to enter in draw-in groove, at the top of the card column chamfering is provided with.
Further, for effectively utilizes space and material, the guiding slot length is equal to guide pad to flexible knob
Distance.
The present invention compared with prior art, have the advantage that for：
(1) present invention makes trolley overall length adjustable, on the premise of former performance is not changed, allows trolley in narrow and small sky
It is interior to use, be conducive to trolley in the transport of small space.
(2) present invention is reasonable in design, and control is flexible, it is easy to installs and safeguards, with very strong practicality.
