Abstract
The safety device of jack for vehicles, comprises ratchet, tooth bar, control lever, clamp; Two ratchet symmetries of strip shape are fixed on same pawl axis, and pawl axis pin joint is on rocking arm; Pawl axis rigidly fixes control lever, the draw-in groove width on the diameter of control lever and clamp is adaptive, and the clamp be fixed on rocking arm is the elastic sheet in U-shaped, has two projections arranged in opposite directions at draw-in groove opening part; Tooth bar symmetry is fixed on the left and right support of jack body, its lengthwise position and ratchet one_to_one corresponding; Along with on jack body take over a business lifting time, ratchet droops under gravity and drags on tooth bar; When taking over a business seat and declining suddenly for some reason, the tip of ratchet can be stuck in the serration pit of tooth bar, makes to be fixed on taking over a business seat and cannot continue to fall on rocking arm, thus protects operator under car.Benefit of the present utility model is: can prevent from seat surprisingly to drop and injure the person.The utility model structure is simple, and compact is applied widely.
Description
Technical field
The invention belongs to maintenance facility field, relate to the safety device of jack for vehicles specifically, after jacking automobile, can prevent unexpected decline from injuring operator.
Background technology
Hydraulic jack for use in vehicle is the conventional tool of vehicle maintenance and repair maintenance, referring to accompanying drawing 1, is generally placed in garage or in maintenance factory and uses, be widely used.But the shortcoming of this product also clearly, do not possess long support function, because hydraulic system fault easily surprisingly lost efficacy, and the ascending, descending of jack all by lever operated come, the reasons such as easy maloperation, jack can be caused surprisingly to decline and injure the operator under car, therefore only by after hydraulic jack jack-up automobile, just great risk is maintained to automobile, if be equipped with security bracket more in addition to support, not only complicated operation but also improve maintenance cost, adds taking up room of support.
Summary of the invention
The object of the invention is to the defect overcoming prior art, provide the safety device of jack for vehicles, structure is simple, compact, economical and practical.
Technical scheme of the present invention is:
A safety device for jack for vehicles, is characterized in that: on jack body, there is also mounted protective device;
Described protective device comprises ratchet, tooth bar, control lever, clamp; Two ratchet symmetries of strip shape are fixed on same pawl axis, and pawl axis pin joint is on rocking arm; Pawl axis rigidly fixes control lever, the draw-in groove width on the diameter of control lever and clamp is adaptive, and the clamp be fixed on rocking arm is the elastic sheet in U-shaped, has two projections arranged in opposite directions at draw-in groove opening part; Described tooth bar symmetry is fixed on the left and right support of jack body, its lengthwise position and ratchet one_to_one corresponding; Along with on jack body take over a business lifting time, ratchet droops under gravity and drags on tooth bar; When taking over a business seat and declining suddenly for some reason, the tip of ratchet can be stuck in the serration pit of tooth bar, makes to be fixed on taking over a business seat and cannot continue to fall on rocking arm, thus protects the operator under car.
The invention has the beneficial effects as follows: after automobile jacking, utilize two ratchet supports on tooth bar, the seat of taking over a business of jack is withstood, prevents it from surprisingly dropping and injure the person.Indirect effect is: rocking arm, when weight lifting, because ratchet adds two strong points to rocking arm, makes support more firm stable.Structure of the present invention is simple, compact, connects firm, simple operation, is adapted at the jacking on hydraulic jack and motor-driven jack and support.

1 ratchet, 1-1 pawl axis, 2 tooth bars, seat taken over a business by 3 rocking arms, 4 connecting rods, 5,6 left socles, 7 right supports, 8 handles, and 9, control lever, 10 clamps, 10-1 draw-in groove, 10-2 is protruding, 11 hydraulic efficiency pressure systems.
Detailed description of the invention
The present invention is introduced in detail below, so that those skilled in the art's profound understanding by drawings and Examples.
Embodiment
The present embodiment employs a kind of safety device of hydraulic jack for use in vehicle, and its structure is as shown in Fig. 2-Fig. 6, and protective device comprises ratchet 1, tooth bar 2, control lever 9, clamp 10; Referring to Fig. 4, Fig. 5, two ratchet 1 symmetries of strip shape are fixed on same pawl axis 1-1; Described pawl axis 1-1 pin joint is on rocking arm 3; Pawl axis 1-1 rigidly fixes control lever 9, the draw-in groove 10-1 width on the diameter of control lever 9 and clamp 10 is adaptive; Referring to Fig. 3, the clamp 10 be fixed on rocking arm 3 is the elastic sheets in U-shaped, at the protruding 10-2 that draw-in groove 10-1 opening part has two to arrange in opposite directions.
Referring to Fig. 2, Fig. 4, tooth bar 2 symmetry is fixed on the left socle 6 of jack body, right support 7, its lengthwise position and ratchet 1 one_to_one corresponding.
When using jack, pressing handle 8 continuously, under the effect of hydraulic efficiency pressure system 11, connecting rod 4 will be taken over a business seat 5 and up be lifted, and pin joint is taking over a business the rocking arm 3 of seat 5 also along with kicking up, and ratchet 1 droops dragging on tooth bar 2 under gravity; Just in case take over a business seat 5 when declining suddenly for some reason, the tip of ratchet 1 can be stuck in the serration pit of tooth bar 2, makes to be fixed on taking over a business seat 5 and cannot continue to fall on rocking arm 3, thus protects operator under car.
If need to put down weight, then need again slightly by weight jack-up a bit, referring to Fig. 6, then control lever 9 is firmly dialled backward, when draw-in groove 10-1 made a forcible entry into by control lever 9, control lever 9 can be pushed two protruding 10-2 of draw-in groove 10-1 opening part open, after control lever 9 enters draw-in groove 10-1 toward both sides, two protruding 10-2 reset, and make control lever 9 can not deviate from draw-in groove 10-1 easily; Now, be picked up and depart from tooth bar 2 in two ratchet 1 tips, weight can put down by operator as ordinary jack.
The invention has the beneficial effects as follows: after automobile jacking, utilize two ratchet supports on tooth bar, the seat of taking over a business of jack is withstood, prevents it from surprisingly dropping and injure the person.Indirect effect is: rocking arm, when weight lifting, because ratchet adds two strong points to rocking arm, makes support more firm stable.Structure of the present invention is simple, compact, connect firm, do not change original operating habit, be adapted at the jacking on hydraulic jack and motor-driven jack and support.
