Abstract
The utility model discloses a jack with bolts. The jack comprises a base, a rising element and a tray. The side edges of the base are fixedly provided with at least two fixing blocks, the fixing blocks are provide with second through holes and third through holes, the second through holes and the third through holes are on the same horizontal plane, and nuts are fixedly arranged on the second through holes and the third through holes. The jack is further provided with the bolts, the bolts penetrate through the second through holes and are in threaded connection with the nuts, and the bolts penetrate through the third through holes and are in threaded connection with the nuts. The tray is supported through the bolts. Even if the rising element is faulty and falls, and accordingly a heavy object falls suddenly, the bolts can support the heavy object and safety hidden risks are eliminated.
Description
Technical field
The utility model belongs to a kind of jack of strap bolt.
Background technology
Jack is that a kind of the top with rigidity lifted part as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw.Can be divided into 3 kinds of tooth bar jack, lifting screw and hydraulic jacks by architectural feature.The kind of car jack can be divided into four kinds of tooth bar jack, lifting screw and hydraulic jack and inflatable jacks.Jack is the simplest weight-lifting equipment of a kind of lifting highly little (less than 1m), and it has two kinds of mechanical type and fluid pressure types.The mechanical type jack has rack-and-pinion and spiral two kinds again, because hoisting capacity is little, the operation effort generally only is used for flight-line maintenance work, and is inapplicable in repairing the bridge process.Fluid pressure type jack structure compactness, stable working has self-locking action, so use extensively.Its shortcoming is that lifting is highly limited, and lifting velocity is slow.Hydraulic jack commonly used also has potential safety hazard, and behind the jack-up weight, weight of heavy may cause hydraulic jack rising part directly to come off, and weight directly falls down, and causes safety misadventure.Need a kind of hydraulic jack that can prevent this class safety misadventure.
Summary of the invention
The utility model is at the prior art deficiency, and a kind of part that prevents from rising safer hydraulic jack that comes off is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of jack of strap bolt, comprise base, rising part and pallet, described chassis side is set with at least two fixed blocks, described fixed block is provided with through hole No. two, on described No. two through holes nut is arranged fixedly, also be provided with bolt, described bolt passes No. two through holes and is connected with nut thread.With bolt tray support is lived, even rising part et out of order, the rising part weight that causes that drops suddenly drops suddenly, and bolt also can support weight, eliminates safe hidden trouble.
In the technique scheme, described pallet downside is provided with the groove that is complementary with bolt.Make things convenient for bolt to support, prevent the bolt skew.
In the technique scheme, described fixed block is fixed on the top of chassis side.Shorten the length of bolt, saved cost.
The utility model compared with prior art has following beneficial effect: the utility model uses bolt to come the extra support pallet, and in order to eliminate when the rising part et out of order, the potential safety hazard that weight directly drops has increased the safety of hydraulic jack.The pallet downside is provided with the groove that is complementary with bolt, makes things convenient for bolt to support, and prevents the bolt skew.Fixed block is fixed on the top of chassis side, has shortened the length of bolt, saves cost.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: embodiment 1: referring to Fig. 1 ~ 4, a kind of jack with latch, comprise base 1, rising part 2 and pallet 3, captive joint one connecting plate 4 on the described pallet 3, pallet 3 is fixing with connecting plate 4 welding, connecting plate 4 and pallet 3 at grade or parallel pallet 3, vertical described connecting plate 4 is fixedly connected with stay bearing plate 5, stay bearing plate 5 is welded on the connecting plate 4, and it is best that connecting plate 4 and stay bearing plate 5 are ferrous material.
Described stay bearing plate 5 other ends are provided with through hole 9, and sliding in the described through hole 9 is provided with latch 6, and latch 6 can be free to slide in through hole 9, but the spacing of latch 6 and through hole 9 inwalls is not again too big, and latch 6 has certain contact with through hole 9.
Described base 1 side is provided with wavy draw-in groove 7, and described latch 6 is complementary with described wavy draw-in groove 7.According to the difference of jack rise height, with latch 6 and wavy draw-in groove 7 combinations that adapt, in conjunction with after, fixed stay bearing plate 5, stay bearing plate 5 and connecting plate 4 vertical fixing, therefore, also fixed connecting plate 4, and connecting plate 4 is fixing with pallet 3 welding, has also just fixed pallet 3.
Described latch 6 is provided with magnet with wavy draw-in groove 7 contact jaws.Magnet is connected latch 6 tightr with wavy draw-in groove 7, prevent that latch 6 from skidding off wavy draw-in groove 7.After pallet 3 withstood weight, weight had individual pressure to pallet 3, and this pressure is extended on the latch 6, and latch 6 is subjected to the effect of this power, might therefore skid off wavy draw-in groove 7, and magnet is set, and had eliminated this problem.
Described latch 6 is set with force rod 8 away from wavy draw-in groove 7 ends.Force rod 8 is set, makes things convenient for latch 6 to push wavy draw-in groove 7, also make things convenient for latch 6 from wavy draw-in groove 7, to extract out.After pallet 3 withstood weight, weight had individual pressure to pallet 3, and this pressure is extended on the latch 6, with hand latch 6 this things was directly pulled out when being stressed, and relatively difficulty is set up force rod 8, physical principle, and latch 6 is easier extracting relatively.
Embodiment 2: compare with embodiment 1, difference is, the supporting way difference of described jack slip-off preventing, and all the other are all identical.
Participate in Fig. 1, Fig. 5 and Fig. 6, a kind of jack of strap bolt comprises base 1, rising part 2 and pallet 3, and described base 1 side is set with at least two fixed blocks 104, fixed block 104 is welded on base 1 side, must be fixed on firmly on base 1 side.Described fixed block 104 is provided with through hole 105 No. two, on described No. two through holes 105 nut is arranged fixedly, nut No. two through holes 105 of fitting, and in the hole of nut is included in by the hole of No. two through holes 105.
Also be provided with bolt 108, described bolt 108 passes No. two through holes 105 and is connected with nut thread.Rotating bolt 108 makes bolt 108 rise or descend.With bolt 108 pallet 3 is supported, even rising part 2 et out of orders, rising part 2 weight that causes that drops suddenly drops suddenly, and bolt 108 also can support weight, eliminates safe hidden trouble.
Described pallet 3 downsides are provided with the groove 109 that is complementary with bolt 108.Groove 109 makes things convenient for bolt 108 to support, and prevents bolt 108 skews.After bolt 108 rose, 108 on bolt entered in the groove 109, and groove 109 is complementary with bolt 108, and bolt 108 is not easy to be offset after entering.Fixedly installed groove 109, also played certain positioning action, whether judged in groove 109 whether bolt 108 is offset after can rising by bolt 108.
Described fixed block 104 is fixed on the top of base 1 side.It is more top that fixed block 104 arranges, and needs the length of bolt 108 just more short, shortens the length of bolt 108, can save cost.
