Description
Technical field
Jack is the utility model is related to, more particularly to a kind of scissor-like jack.
Background technology
In order to tackle the catastrophic failure of vehicle, the scissor-like jack of Simple portable is usually equipped in boot, in case not
When need, but the probability that vehicle breaks down is not high, and idle jack device does not also add because long-time is not used
Lubricating oil, cause device to get rusty and be difficult with, and the threads of lead screw of scissor-like jack passes through mounting rod, when long-term without after getting rusty
It is difficult to convenient rotational lead screw enables jack to be used, and it is very inconvenient at this point for the lubrication operation at place of getting rusty,
Lubrication operation can not be rapidly performed by after lubricating oil addition, uses cumbersome and inconvenient victory, the space that could be improved.
Utility model content
The purpose of this utility model is to provide a kind of scissor-like jack, and easily device can be moistened when in use
Sliding processing so that rapid operation, it is easy to the derusting lubricated of jack left unused for a long time, it is easy to use.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of scissor-like jack, including be hinged upper arm and underarm, be arranged in upper arm and underarm hinged place is grasped
The leading screw of work and the fix bar worn for leading screw and mounting rod, offer in the fix bar and worn for leading screw and madial wall is smooth
Perforation, the screwed hole for offering and coordinating for threads of lead screw, one end end face of the mounting rod are run through in the side of the mounting rod
Offer the oil filler point for being communicated in screwed hole.
Using such scheme, screw mandrel is arranged in fix bar and mounting rod realizes that position is fixed, and passes through the screw thread with fix bar
Hole is fixed and adjusted, and the oil filler point on the end face of mounting rod one end is communicated in screwed hole, when screw mandrel is arranged in screwed hole,
Operation directly can be lubricated to screw mandrel side by oil filler point, directly the connection contact position of screw mandrel and mounting rod is carried out
Lubrication operation, more directly, fast, use is more flexible, convenient for easy to operate and lubrication.
Preferably, the oil filler point is set from the end slope of mounting rod to screwed hole side.
Using such scheme, oil filler point being obliquely installed so that consolidating in mounting rod from the end face of mounting rod to screwed hole side
When fixed pendulum is put, the lubricating oil in oil filler point smoothly can flow to screwed hole side under gravity, be easy to lubrication operation, make
With more convenient.
Preferably, the side wall of the screwed hole is along hole axle to offering the oiling groove that is communicated in screwed hole and oil filler point.
Using such scheme, the oiling groove of the side wall of screwed hole is communicated in oil filler point and screwed hole, and along screwed hole
It is axially extending so that the axial direction of oil filler point and screwed hole keeps connected state, can be to screw thread from the oil filler point oiling of side
Hole carries out the lubrication operation of more contacts area simultaneously, and use is more efficient.
Preferably, the oiling groove is sequentially communicated the external diameter in screwed hole.
Using such scheme, oiling groove is communicated in the external diameter of screwed hole so that oiling groove can be lubricated comprehensively, and is communicated in
It is easy to clean oiling groove after external diameter, simple operation.
Preferably, sliding inlay card has the seal for sealed oiling groove in the oiling groove.
Using such scheme, seal slides inlay card in carrying out encapsulation process to oiling groove in oiling groove, avoids not making
Used time is polluted to oiling groove, is easy to manage, and the lubricating oil that can be guided in oiling groove is lubricated along oiling groove
Operation so that lubrication is more uniform, avoids lubricating oil from being overflowed from the both sides of oiling groove and pollutes difficult cleaning.
Preferably, the seal is set close to the side of screwed hole in the arc-shaped mutually isometrical with the external diameter of screwed hole
Put.
Using such scheme, seal is isometrical close to the side side wall and screwed hole external diameter of screwed hole so that seal card
Screwed hole can be sealed when in oiling groove so that screw mandrel can normally carry out installation operation in screwed hole.
Preferably, the seal is provided with two and slides inlay card in oiling groove from the both ends of oiling groove respectively.
Using such scheme, seal is arranged to two and enters line slip inlay card from both sides, conveniently takes, and to correspond to
Oil filler point so that the lubricating oil in oil filler point during seal is taken out smoothly can directly be lubricated operation, cut energy
Encapsulation process is carried out from both sides, avoids causing the pollution to mounting rod in the operation that dismounting seal is lubricated.
Preferably, the end bending that the seal protrudes from mounting rod is extended with the hook for being easy to hand to catch on lifting
Ring.
Using such scheme, the hook ring bending of seal protrusion, which is set, is easy to putting forth effort for finger, when in use more
It is convenient, it is laborsaving.
Preferably, one end of the oil filler point is covered with the end cap for sealed oiling hole.
Using such scheme, the end cap that oil filler point one end covers carries out encapsulation process to oil filler point so that in oil filler point
Lubricating oil will not be leaked easily, and can coordinate the storage carried out after the installation of screw mandrel to lubricating oil, easy to use, hygienic.
In summary, the utility model has the advantages that：
1st, the side of mounting rod directly opens up oil filler point and is lubricated operation around the screw mandrel into screw thread, using more
It is convenient, practical；
2nd, fit seal and oiling groove make it that the operation of oiling is more comprehensive, can cause the screw mandrel and mounting rod to get rusty
It is quickly and easily easy to use efficiently by lubrication by being difficult to action after installation.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of scissor-like jack disclosed in the present embodiment, as shown in Figures 1 and 2, including equal two upper arm 11 of brachium and
Two underarms 12, upper arm 11 offer mounting hole with the both sides of underarm 12 in junction, and mounting hole is equipped with mounting rod 2 and consolidated respectively
Upper arm 11 and underarm 12 are hingedly mounted on and realize flexible connection together by fixed pole 3, mounting rod 2 and fix bar 3.Also include Rocker arm 5
And the leading screw 4 being fixedly connected with Rocker arm 5, leading screw 4 sequentially passes through fix bar 3 and mounting rod 2, and is driven under the rotation of Rocker arm 5
The rotation of leading screw 4 and then the whole height change for realizing upper arm 11 and the angulation change adjustment jack of underarm 12.
As shown in Figures 2 and 3, the center of fix bar 3 and mounting rod 2 offers perforation and screwed hole 21, fix bar 3 respectively
On the smooth non-threaded of perforation madial wall, leading screw 4 can be smoothly arranged in perforation and side is connected to perforation away from screwed hole
21 side；Perforate 41 is offered in the side wall that the opposite side leading screw 4 of perforation is worn out, finite place piece 42 is inserted in perforate 41,
The position of leading screw 4 and perforation is defined into placement to slide；The screwed hole 21 opened up on mounting rod 2 is matched somebody with somebody with 4 mutual screw thread of leading screw
Close so that leading screw 4 drives upper arm 11 and the hinged place at the both ends of underarm 12 that relative displacement occurs after rotating, according to isoceles triangle
