Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figures 1 to 7, be provided with a kind of telescopic fork of forklift truck supplementary structure, including bottom plate 1, bottom plate 1 for
The installation screw 18 that the pallet fork 17 is connected；Structure identical the first telescoping mechanism 2a and second is symmetrically arranged with bottom plate 1 to stretch
Contracting mechanism 2b.
First telescoping mechanism 2a includes pitching 5a on fork 4a and first in the first bottom fork 3a, first.
Fork 4a is by rack pinion in the fork 3a and first of first bottom, i.e. the first bottom, which is pitched, sets second time rack on 3a
10a, setting the is provided with the middle of the second upper rack 10a ＇, second time rack 10a and the second upper rack 10a ＇ in first on fork 4a
Two gears 10, second gear 10 is meshed with second time rack 10a and the second upper rack 10a ＇.
Pitch 3a and pitch 4a to being provided with some second directive wheel 14a, first on the side wall of the side of mediation member 6 in the first bottom
On be provided with the second chute 14a ＇ being engaged with the second directive wheel 14a；The side of first bottom fork 3a dorsad sides of mediation member 6
It is provided with some 3rd directive wheel 15a, first to pitch on wall and is provided with the 3rd be engaged with the 3rd directive wheel 15a on 4a
Chute 15a ＇.
Fork 5a is provided with gear train 9, tooth by being pitched in rack pinion, i.e., first in 4a on the fork 3a and first of first bottom
Wheel group 9 is pitched the first time rack 9a set on 3a with the first bottom and engaged；Gear train 9 and be arranged on first pitch 5a on first on
Rack 9a ＇ are engaged.
The fork 5a left and right sides on guide groove 16a ＇, first is provided with the both sides side wall for pitching 4a in first to be provided with and lead
The guide pad 16a being engaged to groove 16a ＇, guide pad 16a and guide groove 16a ＇ cooperation, make fork 5a on first be pitched in first
Motion on 4a is more stablized.
The mediation member 6 of " ten " shape is provided with the middle of first telescoping mechanism 2a and the second telescoping mechanism 2b, centre is passed
The side external part of moving part 6 is fixedly connected with pitching 4a in first, opposite side external part and the second telescoping mechanism 2b second in pitch 4b
It is fixedly connected, mediation member 6 is fixedly connected with the first driving rack 8b.
Mediation member 6 is fixedly connected with the first sliding block 11a, bottom plate 1 admittedly with being pitched in first under the external part that 4a is connected
Surely the first slide rail 11a ＇, the first sliding block 11a is provided with to be engaged with the first slide rail 11a ＇；4b is pitched in mediation member 6 and second
It is fixedly connected with the external part of connection on the second sliding block 11b, bottom plate 1 and is fixedly installed the second slide rail 11b ＇, the second sliding block 11b
It is engaged with the second slide rail 11b ＇.Slide rail, sliding block can play supporting, guide effect to the motion of mediation member 6.
Hydraulic jack 7, hydraulic jack 7 are provided with bottom plate 1 between the first telescoping mechanism 2a and the second telescoping mechanism 2b
Piston rod on be connected with first gear 8, first gear 8 is engaged with the first driving rack 8b, and therefore, first gear 8 is in hydraulic pressure
When being moved reciprocatingly under the drive of the piston rod of oil cylinder 7, the first driving rack 8b being meshed with first gear 8 can drive middle biography
Moving part 6 does corresponding motion.It is fixedly installed on bottom plate 1 on gib block 12, gib block 12 and some first directive wheels 13 is set, the
The one driving rack 8b rack back side is resisted against on the first directive wheel 13.First directive wheel 13 is then the first driving rack 8b fortune
It is dynamic that supporting, guide effect are provided.
The first guiding rack 8a is fixedly installed in the first driving rack 8b opposite sides on bottom plate 1, first is oriented to rack
8a is engaged with first gear 8.
Second telescoping mechanism 2b is symmetrical arranged with the first telescoping mechanism 2a, and structure is identical, and here is omitted.
When need to use the present invention, the present invention is installed on the pallet fork 17 of fork truck, is specially to pass through installation screw with bolt
18 are fixedly mounted on bottom plate 1 on pallet fork 17.When fork truck needs the goods for forking vehicle body side, hydraulic jack 7 provides power, liquid
The piston rod of compressing cylinder 7 stretches out, and promotes the first gear 8 connected on piston rod to travel forward, and first is oriented to rack 8a to first
The motion of gear 8, which rises, is oriented to fixation.Therefore the first driving rack 8b being meshed with first gear 8 also drives intermediate transmission
Part 6 travels forward.Wherein, the first 13 couple of first driving rack 8b of directive wheel set on gib block 12 motion, which rises, to be oriented to, determines
Position and supporting role；The first sliding block 11a, the first slide rail 11a ＇ and the second sliding block 11b and the second slide rail 11b ＇ are passed to centre simultaneously
The motion of moving part 6 plays supporting and guide effect.Under the drive of mediation member 6, in first be connected with mediation member 6
Fork 4b also makees synchronized motion forward in fork 4a and second.By taking the first telescoping mechanism 2a motion as an example, 4a fortune is pitched in first
When dynamic, second gear 10 and second time rack 10a being meshed therewith, the second upper rack 10a ＇ are the fortune of fork 4a in first jointly
It is dynamic that guiding, positioning action are provided.Fork 4a passes through the second directive wheel 14a, the 3rd directive wheel 15a in the first bottom fork 3a and first simultaneously
The connection that the mode being connected with respective slide slots makes the first bottom pitch in 3a and first between fork 4a is more consolidated, while to first
Middle fork 4a motion play the guiding role.Further, because in first fork 4a move, make in being arranged on first inside fork 4a
Gear train 9 rotates, because gear train 9 is engaged with first time rack 9a and the first upper rack 9a ＇ simultaneously, so pitching 5a on first
Corresponding propulsion also occurs under the drive of gear train 9.Guide groove 16a ＇ and guide pad 16a cooperation are then to pitching on first
5a motion, which rises, to be oriented to and fixation.Pitched in first on 4a and first after fork 5a stretchings, you can fork positioned at fork truck body side
The goods in face.On the contrary, when fork truck need to advance, the piston rod of hydraulic jack 7 shrinks, in driving corresponding first on fork 4a and first
Fork 5a, which shrinks, to be parked on the fork 3a of the first bottom, and the traveling of fork truck is not influenceed.2a pairs of second telescoping mechanism 2b and the first telescoping mechanism
Claim to set, structure is identical, and motion principle is identical, and here is omitted.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
