Abstract
The utility model relates to a jack of pressing hand improvement. The purpose is the paint that the pressing hand position should be able to effectively be protected to the jack that provides, still has simple structure's characteristics. Technical scheme is: a jack of pressing hand improvement, include by the wallboard constitute and the bottom surface be equipped with the wheel the base, install on the base and including the fuel pump assembly of hydro -cylinder and oil pump, order about the pressing hand of oil pump pump core motion and be connected the handle that just can wave from top to bottom with pressing hand, the top of wallboard transversely is fixed with one and is used for preventing the pressing hand cylindrical pin of wobbling left, its characterized in that: pressing hand last with the contacting area pin be with the arc surface that the pin suited. Cylindrical pin is the steel pin.
Description
Technical field
This utility model is related to a kind of jack, especially a kind of jack for pressing handss improvement.
Background technology
As shown in Fig. 2 the jack of routine, is set with plastics baffle ring on pin, can prevent from pressing handss excessively swinging to the left
Incline;When pressing handss stress and swinging to the left, it is welded on and presses the steel sheath of handss outer surface and can encounter plastics baffle ring 6, so can be with
The paint that protection is pressed on hand will not be damaged.The shortcoming of this structure is, if the strength pressed when handss are swung to the left is excessive, easily damages
Bad plastics baffle ring, causes to press handss toward left bank, damages stressed member.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of jack for pressing handss improvement, should
Jack should be able to effective protection press the paint of hand position, also with simple structure the characteristics of.
This utility model provide technical scheme be:
It is a kind of press handss improvement jack, including be made up of wallboard and bottom surface equipped with wheel base, on base
And the oil pump component including oil cylinder and oil pump, order about oil pump pump core motion press handss and with press what handss were connected and can fluctuate
Handle, the top of the wallboard are laterally fixed with one for preventing from pressing the cylindrical pin that handss are swung to the left;It is characterized in that:Press
It is the arc surface being adapted with the pin on hand with the contact site of pin.
The cylindrical pin is steel pin.
This utility model beneficial effect is:
As pin is steel pin, press and make the arc surface being adapted with pin on hand with the contact site of pin again,
This utility model moves excessive to left swing after can both preventing from pressing handss stress, and easy damaged does not press the paint of hand position;Thus the knot
Structure is simple and practical.
Description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is the structural representation of existing jack.
Fig. 3 is the A portions mplifying structure schematic diagram in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, it is a kind of press handss improvement jack, including be made up of wallboard 1 and bottom surface equipped with wheel base, peace
Be mounted on base and the oil pump component including oil cylinder and oil pump, order about the motion of oil pump pump core press handss 2 and with press handss be connected and
The handle 3 that can be fluctuated, the top of the wallboard are laterally fixed with one for preventing from pressing the cylinder gear that handss are swung to the left side
Bar 4, above structure are similar with the conventional structure of jack.
It is of the present utility model to the improvement is that:
One is, by the enlarged diameter of pin, to allow and press handss and remove the steel pin directly contact after plastics baffle ring;Due to steel
Matter pin is securely fixed on wallboard, thus can be prevented effectively from and press handss and turn left when handss reciprocally swinging (swinging around axle 2-1) is pressed
The amplitude of swing is excessive.
Two is will to press to make and the gear with the contact site of pin (be welded on press handss outer surface steel sheath) on hand
The arc surface 5 that bar is adapted.When pressing handss stress amplitude of fluctuation being excessive to the left, pin can be stopped, prevent from pressing handss to the left
Incline, protection stressed member is without damage;Simultaneously as it is shiny surface to press outside handss with the contact surface of pin, and it is and circle
The arc surface that cylindricality pin is adapted, that is, the radian for pressing arc surface on hand are matched with the radian of cylindrical pin, therefore are pressed
When strength that handss are contacted with pin is excessive, the paint pressed on hand is also not easy to be knocked bad, and service life is also extended.
Claims (2)
1. it is a kind of press handss improvement jack, including is made up of wallboard (1) and bottom surface be equipped with wheel base, on base
And the oil pump component including oil cylinder and oil pump, order about pressing handss (2) and being connected and can shake up and down with handss are pressed for oil pump pump core motion
Dynamic handle (3), the top of the wallboard are laterally fixed with one for preventing from pressing the cylindrical pin (4) that handss are swung to the left, its
It is characterised by:It is the arc surface (5) being adapted with the pin on hand with the contact site of pin to press.
It is 2. according to claim 1 to press the jack that handss are improved, it is characterised in that:The cylindrical pin is kept off for steel
Bar.
