Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As Fig. 1 is to shown in 5, and a kind of hand steered fork truck of lightweight, including sole 1, two pivoted frames being rotatably installed in sole 1 left and right sides respectively, it is vertically installed at the universal wheel 6 bottom pivoted frame, is horizontally arranged at the auxiliary wheel 7 bottom pivoted frame, and is movably arranged on the connecting plate 4 at pivoted frame top.
Pivoted frame includes crossbearer 2 and the vertical frame 3 being connected with crossbearer 2 front end, sole 1 has two optical axises being parallel to each other 1.1, crossbearer 2 is a cylindrical bar, its diameter is more than the diameter of optical axis 1.1, one is offered along its axially extended installing hole on cylindrical bar, optical axis 1.1 inserts and realizes in installing hole being rotatably assorted, and makes the vertical frame 3 can be around the axis left-right rotation of crossbearer 2.
Realize locking by locking member between sole 1 and pivoted frame and unlock；Locking member includes latch 9, the first spring 10, the second spring 12, stay cord 14 and handle 11；All offering, on crossbearer and sole, the pin-and-hole allowing that latch 9 inserts, the first spring 10 is sleeved on latch 9 periphery and its one end is connected with crossbearer, the other end is connected with the outer end of latch 9；One end of handle 11 is hinged on pull bar, and one end of stay cord 14 is connected with the outer end of latch 9, the other end is connected with handle 11, and one end of the second spring 12 is connected with pull bar, the other end realizes handle 11 reset with being connected inside handle 11；Swing handle 11 can drive latch 9 to move in pin-and-hole.When vertical frame 3 is perpendicular to ground 8, two pin-and-holes alignment, latch 9 inserts under the first spring 10 pressure effect in two pin-and-holes thus is locked with pivoted frame by sole 1, and swing handle 11 latch 9 is the most movable thus realize unblock under stay cord 14 pulling force effect.For fixed pulling rope 14, vertical frame being additionally provided with rope sling 13, stay cord 14 is movably fixed in rope sling 13.Pivoted frame, connecting plate 4 and sole 1 form parallel four-bar linkage.
The top of connecting plate 4 is also equipped with pull bar 5, pull bar 5 have be easy to user just draw, oblique pull and the multistage warp architecture of rotating vertical frame 3.Vertical frame 3 peace that includes being hinged holds montant 3.1 and upper montant 3.2, and upper montant 3.2 can rotate forward around pin joint consequently facilitating control fork truck, and lower montant 3.1 is connected with crossbearer 2, and upper montant 3.2 is hinged with connecting plate 4.
The operation principle of the present invention and process
The crossbearer 2 of pivoted frame has the pallet fork function of existing hand fork lifter concurrently, at this fork truck mobile to goods to be handled, pull up latch, then hand rotation vertical frame 3 makes the height of crossbearer 2 and sole 1 be dropped to H2 by H1, when dropping to auxiliary wheel 7 and contacting ground 8 its supporting role, now by auxiliary wheel 7, crossbearer 2 can be moved to tray bottom.Now hand rotation vertical frame 3 makes it recover plumbness, crossbearer 2 and sole 1 are the most gradually raised up to elemental height H1, in the process, auxiliary wheel 7 leaves ground 8 and universal wheel 6 contacts ground 8 its supporting role, crossbearer 2 supports the bottom of its pallet so that goods connection pallet is together loaded on crossbearer 2, latch is also inserted locking crossbearer 2 and sole 1 prevents it from rotating in the action of gravity of goods vertical frame 3 of ordering by pin-and-hole alignment, now pulls pull bar 5 that this fork truck just can move the carrying realizing article to target location.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
