Cumbersome screens step, adds convenience.
Technical means, creative features, achievable purpose and effectiveness to realize the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of portable type tray truck, including backrest 1, pallet fork 2, walking two-wheel 3, supporting rack 4, oil
Pump 5, rear walking wheel 6, supporting rod 7, handle 8, switch 9, tablet 10, shaft 11 and ratchet mechanism 12,1 right end of backrest and pallet fork 2
It is welded, 2 bottom right of pallet fork is provided with walking two-wheel 3, and 1 left side of backrest is bolted with supporting rack 4, and oil pump 5 is pacified
Mounted in 4 right side of supporting rack, 5 top of oil pump is connected with 1 inside of backrest, and 4 bottom of supporting rack is equipped with rear walking wheel 6, supporting rack 4
Top connection support bar 7,7 top of supporting rod are provided with handle 8, and 7 right hand top of supporting rod is provided with switch 9, and 2 outside of pallet fork is set
Tablet 10 is equipped with, shaft 11 is provided between 2 junction of tablet 10 and pallet fork, 11 left side of shaft is provided with ratchet mechanism 12, spine
Wheel mechanism 12 is made of movable disk 121, ratchet 122 and pawl 123, and 121 middle part of movable disk is rotatablely connected with shaft 11, spine
Wheel 122 is mounted on 121 left side of movable disk, and pawl 123 is arranged on 122 upper end of ratchet and is engaged with ratchet 122 and is connected, ratchet
122 are fixedly connected with pallet fork 2, and pawl 123 is fixedly connected with tablet 10.
Wherein, 10 top end surface of tablet is provided with non-slip texture, can increase the frictional force of tablet 10 and cargo, prevent
The problem of rocking during cargo transport causes to drop.
Wherein, the 10 trapezoidal shape of tablet has expanded the area of pallet fork 2, while convenient for subsequent folding and retraction.
Wherein, the tablet 10 is provided with two pieces, can increase area simultaneously for two pallet forks 2.
Wherein, the tablet 10 can overturn 180 degree by ratchet mechanism 12, can be when that need not use tablet 10, downwards
Folding and unfolding will not increase overall volume, occupied space.
Wherein, 121 inside top of movable disk is provided with sliding block 13, and ratchet 122 can be made to live in movable disk 121
It is dynamic, so as to when tablet 10 can be overturn, while it is parallel with pallet fork 2 when carry out screens, make tablet 10 that there is support force.
Wherein, the tablet 10 is made of steel plate, and surface spraying is by anticorrosive paint, and intensity is high, while anticorrosive paint
Steel plate can be protected to prevent from getting rusty.
Wherein, the ratchet 122 is J6060A models, and torque is small will not to cause too big abrasion, and service life is long.
Described in this patent：Ratchet mechanism 12, a kind of one-way intermittent motion mechanism being made of ratchet and pawl.Ratchet machine
Structure is commonly used in various lathes and automatic machine in the indexing of index(ing) feed or rotary table, is also commonly used on jack.Certainly
Ratchet mechanism is used for unidirectional drive in driving, and ratchet mechanism is commonly used to prevent non-return turn in hand winch.When ratchet mechanism works
Noise and vibration are often accompanied by, therefore its working frequency cannot be excessively high.
Operation principle：Cargo is placed on 2 upper end of pallet fork, then by catching handle 8, carries out application thrust, it is then right
Cargo is transported, and by 9 control oil pump 5 of pull-up switch oil pump 5 can be made to provide branch upwards to backrest 1 and pallet fork 2 in transport
Support force so as to lift pallet fork 2, says that cargo is lifted up, and when measurement of cargo is larger, is overturn tablet 10 by ratchet mechanism 12
Extremely parallel with pallet fork 2, pawl 123 moves on ratchet 122, makes ratchet 122 by sliding block 13 in 121 inner-concave of movable disk disk
It is moved on slot, makes tablet 10 that can be blocked after digging upwards, so that tablet 10 can increase the area of pallet fork 2, branch is provided to cargo
Support force is provided with non-slip texture on the surface of tablet 10, can increase the frictional force of cargo and 10 surface of tablet, prevent cargo from transporting
It being rocked when defeated and causes to drop, after use, tablet 10 is stirred upwards, pawl 123 leaves 122 surface of ratchet, so that
Tablet 10 can folding and unfolding downwards return, so that the space occupied will not be increased, by the ratchet mechanism 12 of setting, solve cumbersome
Screens step, adds portable type, the portable type tray truck, by being provided with tablet 10 in the outside of pallet fork 2, transport compared with
During big cargo, tablet 10 can be opened, for increasing 2 entire area of pallet fork, increases stabilization during transport cargo, in 10 table of tablet
Face be provided with non-slip texture, the problem of the frictional force with cargo can be increased, prevent from rocking so as to drop during cargo transport, by
11 left side of shaft is provided with ratchet mechanism 12, for blocking tablet 10 when tablet 10 is parallel with pallet fork 2, while can pass through pawl
123 are connected with the engagement of ratchet 122, when that need not use tablet 10, facilitate the quick downward folding and unfolding of tablet 0, reduce numerous
Trivial screens step adds convenience, and sliding block 13 moves for ratchet 122 in movable disk 121, is not in ratchet 122
The problem of off-direction, movable disk 121 enable tablet 10 to do flip-flop movement with pallet fork 2 for the activity with shaft 11.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
