Description
Technical field
This utility model relates to a kind of jack, particularly to one warning jack.
Background technology
Jack is the simplest crane gear that a kind of lifting is the least.Jack is divided into mechanic jacks and hydraulic pressure thousand
Two kinds of jin top, principle is had nothing in common with each other.For from principle, hydraulic jack the principle on which is pascal's principle, it may be assumed that liquid
Pressure everywhere is consistent, and so, in the system of balance, the pressure that smaller piston upper applies is smaller, and big
Piston on apply pressure the biggest, so can keep the static of liquid.So by the transmission of liquid, can obtain
Different pressure on different ends, thus can reach the purpose of a conversion.We the common hydraulic jack arrived just
It it is the transmission that make use of this principle to reach power.Mechanic jacks uses theory of mechanics, and back and forth to pull handle, pusher dog is i.e. arranged
The revolution of dynamic ratchet gap, cone pinion drives large bevel gear, makes weight lifting screw rod rotate so that jacking sleeve acquisition hoists or under
Fall, and reach the function of lifting pulling force.
At present, daily life and work are frequently encountered the situation needing to be lifted by weight, at this time will use thousand
Jin top, common jack does not detect the function of pressure, and when bracing force is excessive, pressure can make supported objects generation shape
Become, even supported objects is damaged.
Utility model content
(1) to solve the technical problem that
The problem that this utility model solves is to provide one and supported objects is had protective effect, has warning function
Jack.
(2) technical scheme
For solving above-mentioned technical problem, this utility model provides a kind of warning jack, including rocking handle, gear one, gear
Two, screw rod, housing and top cover, described rocking handle is connected to described gear one, and described gear one tooth is connected to described gear two tooth, institute
Stating and be provided with screwed hole in the middle of gear two, described screw rod penetrates in the middle of described gear two by described screwed hole, described screw rod
On screw thread match with the screw thread on screwed hole, described top cover is positioned at above described screw rod, and described top cover top is provided with pressure
Force transducer, described housing is provided with pressure alarm.The pressure sensitive sheet of described pressure transducer, by jack with supported
Pressure feedback between object is to pressure alarm, if pressure size exceedes setting value, pressure alarm sends alarm.
Wherein, described support seat is positioned at the bottom of described gear two, and described gag lever post is positioned at the top of described gear two.
Wherein, gear more than described in the gear ratio of described gear two, and pass through between two gears to be the company engaged by tooth
Connect mode, just can be effectively realized and the power of applying is magnified, and improve transmission efficiency.
Wherein, when described gear two rotates, it is impossible to fixed, otherwise will be unable to rotate, so gag lever post is with gear two not
It is connected.
Wherein, described gear one is positioned at described housing, and described gear two is positioned at described housing, and described support seat is positioned at
In described housing, described gag lever post is positioned at described housing, and described screw rod is positioned at described housing.
(3) beneficial effect
The pressure produced when this utility model makes operator can control jack operation bears energy in supported objects
Within power, prevent from causing deformation and the damage being made into object.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model warning jack；
In figure, 1-rocking handle, 2-gear one, 3-gear two, 4-supports seat, 5-screw rod, 6-gag lever post, 7-top cover, 8-pressure
Sensor, 9-pressure alarm, 10-housing, 11-screwed hole.
Detailed description of the invention
For the technological means making this utility model be realized, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with specific embodiment and diagram, this utility model is expanded on further.
Embodiment one: refering to Fig. 1, this utility model provides a kind of warning jack, including rocking handle 1, gear 1, gear
23, supporting seat 4, screw rod 5, gag lever post 6, housing 10 and top cover 7, described rocking handle 1 is connected to described gear 1, described gear one
2 are connected to described gear 23, are provided with screwed hole in the middle of described gear 23, described screw rod 5 by described screwed hole penetrate in
In the middle of described gear 23, the screw thread on described screw rod 5 matches with the screw thread on screwed hole 11, and described top cover 7 is positioned at described spiral shell
Above bar 5, described top cover 7 top is provided with pressure transducer 8, and described housing 10 is provided with pressure alarm 9.Described pressure passes
The pressure sensitive sheet of sensor 8, by the pressure feedback between jack and supported objects to pressure alarm 9, if pressure is big
The little setting value that exceedes, pressure alarm 9 sends alarm.Described support seat 4 is positioned at the bottom of described gear 23, described gag lever post 6
It is positioned at the top of described gear 23.Gear more than 1 described in the gear ratio of described gear 23, and pass through between two gears to be to pass through
The connected mode of tooth engagement, just can be effectively realized and the power of applying be magnified, and improve transmission efficiency.Described gear 23 revolves
When turning, it is impossible to fixed, otherwise will be unable to rotate, so gag lever post 6 is not attached to gear 23.Described gear 1 is positioned at described
In housing 10, described gear 23 is positioned at described housing 10, and described support seat 4 is positioned at described housing 10, described gag lever post 6
Being positioned at described housing 10, described screw rod 5 is positioned at described housing 10.
Rotation crank 1, drives gear 1 to rotate by the connecting rod on rocking handle 1, the most again by gear 1 driven gear
The rotation of 23, when gear 23 rotates, middle screw rod 5 is relatively rotated with gear 23 by screw thread, and gear 23
Defined with gag lever post 6 to move up and down, so causing screw rod 5 up to rotate, so that top cover 7 plays jack-up thing by supporting seat 4
The effect of block, if the pressure size between thing block and pressure transducer 8 exceedes setting value, pressure alarm 9 sends warning.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
