Description

A kind of ultra-thin lifting machine

Technical field:

The utility model relates to the improvement of ultra-thin lifting machine structure.

Background technology:

Ultra-thin lifting machine mainly is fit to the maintenance of short chassis car, and the table surface height after the lifting machine falls is no more than 115 millimeters.Though ultra-thin lifting machine has obtained using widely, but also there is following shortcoming: 1, the lock gear mechanism loading strength deficiency of ultra-thin lifting machine: because dead bolt is fixed on the axle of jam plate top groove, when the locked tooth bar of dead bolt, dead bolt rides on the base of weakness of jam plate groove, be difficult to carry the heavy duty of this machine, easily fracture at the place, base of groove; 2, dead bolt can not enter in the tooth bar very soon: the bottom of existing dead bolt is the plane, during the lock tooth, easily push up mutually with the tooth top of tooth bar the baseplane of dead bolt, and dead bolt can not enter between the tooth of tooth bar, and the axial region of dead bolt is fragile, has influenced the normal operation of ultra-thin lifting machine.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of ultra-thin lifting machine that improves lock gear mechanism intensity is provided.

For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises base, and base links to each other with table top by folding stand; One end of hoist cylinder is fixed on the base, the other end is fixed on the folding stand, be provided with the lock gear mechanism of tooth bar and tooth bar between the hoist cylinder upper end, the top of tooth bar is fixed on the transverse axis of folding stand, the top of the rack bore of its structural feature jam plate is provided with cylinder, the pull bar of cylinder links to each other by the hole that lifts of the tie rod hole on the jam plate with the dead bolt bottom, and the axle of dead bolt is fixed in the top of the rack bore of jam plate; The bottom of dead bolt is a triangle, and the top point of triangle is arranged on the axis of dead bolt.

The beneficial effects of the utility model:

1, strengthened the load-carrying capacity of dead bolt:

Because the utility model has been removed the groove on jam plate from, the structure that replaces is: the top of the rack bore of jam plate is provided with cylinder, the pull bar of cylinder links to each other by the hole that lifts of the tie rod hole on the jam plate with the dead bolt bottom, the axle of dead bolt is fixed in the top of the rack bore of jam plate, the most of entity that has promptly kept jam plate, guaranteed the intensity of dead bolt, when the locked tooth bar of dead bolt, the lock gear mechanism is not fragile yet;

When 2, pinning tooth bar, dead bolt is difficult for withstanding the tooth top of tooth bar:

Because the bottom of dead bolt of the present utility model is a triangle, leg-of-mutton top point is arranged on the axis of dead bolt, and dead bolt can not be pushed up mutually with the tooth top of tooth bar; Even also can slip over along leg-of-mutton limit in moment in the top mutually, can not injure dead bolt or tooth bar.

The specific embodiment:

The utility model comprises base 2, and base 2 links to each other with table top 7 by folding stand 3; One end of hoist cylinder 9 is fixed on the base 2, the other end is fixed on the folding stand 3, be provided with the lock gear mechanism 5 of tooth bar 6 and tooth bar 6 between hoist cylinder 9 upper ends, the top of tooth bar 6 is fixed on the transverse axis 8 of folding stand 3, the top of the rack bore 19 of jam plate 4 is provided with cylinder 16, the pull bar 17 of cylinder 16 links to each other by the hole 22 that lifts of the tie rod hole on the jam plate 4 15 with dead bolt 12 bottoms, and the axle 21 of dead bolt 12 is fixed in the top of the rack bore 19 of jam plate 4; The bottom of dead bolt 12 is a triangle, and the top point of triangle is arranged on the axis of dead bolt 12.

Can below rack bore 19, jam plate 4, be provided with supporting plate 10; Can resist the bendability of some tooth bars 6, strengthen lock gear mechanism 5 fastnesses.

Be provided with a groove 20 above the rack bore 19 of jam plate 4, the both sides of axle groove 20 are respectively arranged with screw hole 18; Like this, the axle 21 of dead bolt 12 can be arranged in the groove 20, and the shaft-cup on the axle 21 of dead bolt 12 is fixed in dead bolt 12 on the jam plate 4 by the screw 14 of both sides.

The leg-of-mutton apex angle of dead bolt 12 bottoms is 90 °, and leg-of-mutton long limit can contact with tooth 11 end faces of tooth bar 6.

The utility model promotes table top 7 by hoist cylinder 9.When table top 7 rose, tooth bar 6 rose thereupon, and dead bolt 12 falls between the tooth 11 of tooth bar 6, and the tooth 11 along tooth bar 6 moves one by one; When table top 7 descended, dead bolt 12 just pinned tooth bar 6 automatically, prevented table top 7 to descend.Can start cylinder 16,, lift dead bolt 12 (by hoist cylinder 9 tooth bar 6 being risen a section earlier), tooth bar 6 is descended fast by the tie rod hole 15 on the pull bar 17 pull-up dead bolts 12.
