Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1 ~ Fig. 7, integrated lock jackknife of the present utility model, comprises cutter hub 1 and sheath 2, and described cutter hub 1 is hinged on the leading section of sheath 2, in the present embodiment, the jointed shaft of cutter hub 1 and sheath 2 preferably includes a tapped internal thread bolt 7 and and is with externally threaded external screw thread bolt 8, and internal thread bolt 7 and external screw thread bolt 8 are respectively through lamellar body 22 rear thread docking, this structure easy accessibility, connect reliable, with respect to riveted joint, manually dismounting, without by main equipment.
On described sheath 2, be formed with the storage tank 21 for accommodating described cutter hub 1, sheath 2 is made up of left and right two lamellar bodies 22, on at least one lamellar body 22, be provided with recess 23, on described lamellar body 22, be provided with from this recess 23 positions first leading section trend, backward storage tank 21 notch places one to sheath 2 sidle to groove 24, groove 24 can adopt cutting processing, be positioned at groove 24 and form locking plate 3 by the lamellar body part of storage tank 21 notch one sides, described cutter hub 1 snaps onto after storage tank 21, is locked with these locking plate 3 tight fits.
Preferably on the knife back of described cutter hub 1, be provided with to operate on and coil 4 as of the present utility model, on described locking plate 3, be provided with this and operate on and coil 4 suitable chamferings 31.In conventional art in the time that needs are opened jackknife, be all one and hold sheath 2, another hand utilizes thumb to pinch cutter hub 1 and cutter hub 1 is extracted to storage tank 21, therefore need two hands to coordinate, and in the application, operate on dish 4 and the setting of chamfering 31, and make when needs are opened jackknife, only need force in to operate on by that hand thumb forward end direction of holding sheath 2 and coil 4, cutter hub 1 can be pushed away from storage tank 21, thereby conveniently open jackknife.
Further preferably, the madial wall of described locking plate 3 is provided with holding tank 32 near leading section position, in described holding tank 32, high hardness alloy piece 5 is installed, the madial wall of described high hardness alloy piece 5 flushes with the madial wall of described locking plate 3, this structure makes in the time closing jackknife, locking plate 3 contacts not easy to wear with the root of cutter hub 1, the locking effect of guaranteeing locking plate 3 is permanently effective, high hardness alloy piece 5 can be connected by screw and be fixed on described locking plate 3, also can fix by other known syndetons.
In the present embodiment, on described lamellar body 22, be provided with horizontal sliding bearing 6 in cutter hub 1 and the jointed shaft position of sheath 2, when described cutter hub 1 rotates by described horizontal sliding bearing 6 and described sheath 2 rolling friction, this is to consider that existing outdoor folding cutter adopts cutter shaft pad, or to cause cutter hub 1 folding to be obstructed not smooth for injustice because sheath 2 and cutter hub 1 are polished, use instead after horizontal sliding bearing 6, even if cutter hub 1 and sheath 2 are not the smooth opening and closing that yet can make cutter hub 1 in smooth especially situation, and, this structure is not subject to the impact of assembling dynamics size between two lamellar bodies 22 and makes the folding of cutter hub 1 smooth and easy all the time.Described horizontal sliding bearing 6 can adopt ball bearing, preferably selects needle bearing, and needle bearing has better stability in the time of cutter hub folding.
Adopt the utility model of said structure, by groove 24 being set on the lamellar body 22 at sheath 2, groove 24 is isolated locking plate 3 from lamellar body 22, utilize the variation of cutter hub 1 from blade to knife back position thickness, make in the time that cutter hub 1 is folding, have compared with the knife back of scantling and push locking plate 3 open, the locking plate 3 that is arranged so that of recess 23 is open and has bending elastic force, thereby after cutter hub 1 is folding, locking plate 3 is pressed on cutter hub 1, utilize the incompatible locking cutter hub 1 of close-fitting of locking plate 3 and cutter hub 1, avoid cutter hub 1 surprisingly open and hurt hand or health, stopped corresponding potential safety hazard; Particularly, the bending elastic force of locking plate 3 concentrates on recess 23 positions, when locking cutter hub, whole locking plate 3 is linear states, this structure is conducive to strengthen locking intensity, and in the time holding tight sheath 2, palm is to be directly held on locking plate 3 directly to lock to locking plate 3 is afterburning, so can better strengthen locking force.
For avoiding the stressed surface that exceedes sheath 2 when bending of locking plate 3 to occur lock phenomenon, on described sheath 2, be provided with the inner fovea part 25 across lamellar body 22 and locking plate 3, the banking stop 9 suitable with described inner fovea part 25 is installed in described inner fovea part 25, described banking stop 9 is fixedly connected with described lamellar body 22 by screw, and banking stop 9 plays the effect of limit locking pieces 3 bendings.
The utility model does not change the structure of traditional cutter hub, only recess and groove need be set on sheath, has the features such as simple and reasonable compactness, easy for installation, implementation cost is low.
The above, be preferred embodiments of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
