Seat, is fixed with the connecting cylinder of cylindrical shape on the base, above-mentioned body lower end be embedded in connecting cylinder and body and connecting cylinder it
Between have buffer structure.
Jack with this component when in use, has certain pooling feature in the presence of buffer structure.
Meanwhile, base can increase the contact area with ground so that jack can be placed steadily.Connecting cylinder can increase and this
The connection area of body, also can guarantee that the connective stability of body and base in buffering course.
In base assembly in above-mentioned hydraulic jack, the connecting cylinder is metal material with base and both are logical
Welding is crossed to be fixedly connected with.
In base assembly in above-mentioned hydraulic jack, the connecting cylinder inner side axially has recessed positioning along it
Groove one, the outer body axially has recessed locating slot two along it, above-mentioned fixed also including a positioning strip in strip
The both sides of position bar are embedded at locating slot one and locating slot two respectively.
Positioning strip is embedded on connecting cylinder and body simultaneously, it is ensured that body will not improve it and use relative to base rotation
Stability.
In base assembly in above-mentioned hydraulic jack, described positioning strip is elastomeric material.
In base assembly in above-mentioned hydraulic jack, described positioning strip is wood materials.
Flexible positioning strip can make to avoid positioning strip and body, connecting cylinder rigid contact.
In base assembly in above-mentioned hydraulic jack, described buffer structure is the spring in connecting cylinder,
Top pressure is distinguished on body and base in the two ends of above-mentioned spring.
In base assembly in above-mentioned hydraulic jack, described buffer structure is that the flexibility in connecting cylinder is delayed
Punching pad.
In base assembly in above-mentioned hydraulic jack, described cushion pad it is cylindrical and its two ends have to
The contact edge of its sidepiece protrusion.
In base assembly in above-mentioned hydraulic jack, the quantity at least two of the cushion pad.
In base assembly in above-mentioned hydraulic jack, described buffer structure be spring in connecting cylinder and
Cushion pad, above-mentioned spring and cushion pad interval setting, the spring and buffering pad form a buffer cell, the buffer cell
Quantity at least two.
Spring and cushion pad are applied in combination, and while its stability is higher, shock-absorbing capacity is also relatively good.Certainly, we
Cushion pad is common elastomeric material in case.
Compared with prior art, the base assembly in this hydraulic jack is oriented to by connecting cylinder to body, buffered
Also the connective stability of body and base is can guarantee that in journey, with practical value very high.
Meanwhile, buffer structure is used cooperatively using spring and cushion pad, and its shock-absorbing capacity is good and stability is high.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the base assembly in this hydraulic jack.
In figure, 1, body；2nd, base；3rd, connecting cylinder；4th, spring；5th, cushion pad.
Specific embodiment
As shown in figure 1, the base assembly in this hydraulic jack, hydraulic jack is the He of body 1 of cavity including inside
The push rod and push rod being connected in body 1 stretch out the upper end of body 1, and this component is arranged at the lower end of body 1, including in flat
Base 2, is fixed with the connecting cylinder 3 of cylindrical shape on the base 2, the lower end of above-mentioned body 1 be embedded in connecting cylinder 3 and body 1 with
There is buffer structure between connecting cylinder 3.
The connecting cylinder 3 is metal material with base 2 and both are fixedly connected with by welding.
The inner side of the connecting cylinder 3 axially has recessed locating slot one along it, and the outside of the body 1 axially has recessed along it
The locating slot two for entering, also including a positioning strip in strip, the both sides of above-mentioned positioning strip are embedded in locating slot one and determine respectively
At the groove two of position.
Described positioning strip is elastomeric material.According to actual conditions, described positioning strip is also feasible for wood materials.
Described buffer structure is spring 4 and cushion pad 5 in connecting cylinder 3, and above-mentioned spring 4 and cushion pad 5 are spaced
Set, the spring 4 and cushion pad 5 form a buffer cell, the quantity at least two of the buffer cell.
In order to simplify structure, buffer structure can also use following two reduction procedures：
One, described buffer structure are the spring in connecting cylinder, and top pressure is distinguished in body in the two ends of above-mentioned spring
On base.
Secondly, described buffer structure be the flexo cushion in connecting cylinder.
Described cushion pad is cylindrical and has the contact edge protruded to its sidepiece at its two ends.The number of the cushion pad
