Abstract
The invention relates to a ball installation element used for a gas spring. The ball installation element comprises a shell and a snap spring assembly. A ball socket is arranged at the bottom of the shell. The snap spring assembly comprises two U-shaped buckles and two or more U-shaped lifting springs arranged in parallel. The two ends of each U-shaped lifting spring are provided with sleeve rings. The two U-shaped buckles are located on the left side and the right side of the ball socket respectively and are parallel to the axis of the shell. The U-shaped buckles are inserted into the shell through insertion holes in the front end of the shell. The insertion holes are divided into two sets which are in lateral symmetry. Each set of insertion holes comprises the upper insertion hole and the lower insertion hole. Upper side arms of the U-shaped buckles penetrate through the sleeve rings on the same side at the same time. Long-strip-shaped cross sections of the upper insertion holes are downwards and outwards inclined and long-strip-shaped cross sections of the lower insertion holes are downwards and inwards inclined till the insertion holes are partly communicated with the ball socket. Lower side arms of the U-shaped buckles are driven to be embedded in the ball socket through spring force formed by expanding two side arms of each U-shaped lifting spring outwards. The ball installation element has the beneficial effects that the ball installation element is reliably connected with a ball head bolt, and meanwhile disassembly and assembly are convenient.
Description
Technical field
The present invention relates to a kind of bulb installed part installed for gas spring.
Background technology
Need to install gas spring between the car door and vehicle body of automobile for the buffering of switch gate, and gas spring passes through bulb spiral shell
Bolt and bulb installed part are connected with car door and vehicle body, and ball stud is arranged on vehicle body, and bulb installed part is arranged on gas spring

Line is parallel, be arranged in parallel between U-shaped lifting spring, and U-shaped lifting spring is vertically arranged with U-shaped buckle, and two U-shapeds snap through shell
The jack insertion housing of the leading section of body, U-shaped lifts spring and inserts housing from the bottom slot of housing, and jack is divided into symmetrical setting
Two groups for putting, every group of jack all includes upper jack and lower jack, and two side arms of U-shaped buckle insert respectively jack and lower insert
Hole, in the insertion of U-shaped buckle the side arm of jack be upper side arm, under the insertion of U-shaped buckle the side arm of jack be lower side arm, U-shaped card
Also cross the collar positioned at the same side, the cross section of lower jack and lower jack is strip to the upper side arm of button, the length of upper jack
Stripe-shaped cross section is downwardly and outwardly inclined, and the strip cross section of lower jack is inwardly downward, until local and ball-and-socket insertion, U
The spring force that two side arms of shape lifting spring open laterally drives the lower side arm of U-shaped buckle by the insertion of lower jack and ball-and-socket
Ball-and-socket is partially submerged into, the bulb part of ball stud is clamped.
To prevent ball stud under larger de- pull out force effect, ball-and-socket is accidentally withdrawn, is further limited, the end of lower jack
End takes off along ball stud pulls out direction A or pulls out direction A directions at an acute angle and extend to form self-locking grooves along taking off with ball stud, self-locking grooves
With depth, the lower side arm of U-shaped buckle can be accommodated.
Further limit, there is mounting groove in the leading section of housing, jack and lower jack on the bottom of mounting groove is
Port, is stamped end cap on mounting groove.
For ease of releasing clamping action of the U-shaped buckle to bulb by way of lifting U-shaped and lifting spring, further limit,
Further limit, the top of housing has the lifting groove for unlocking ball stud, lift groove and be located at two sides that U-shaped lifts spring
Between arm, the lifting groove forms lifting socket between the kink and housing of U-shaped lifting spring.
Further limit, the one end for lifting groove extends to the leading section of housing, and in leading section breach is formed, and lifts the another of groove
Pass through sloped transition between one end and the top of housing.
Further limit, the attachment structure of the tail end of housing is the installing hole of the inserted num inserts of housing tail end.
Further limit, U-shaped snaps through a spring steel wire bending and forms, U-shaped lifting spring passes through a spring steel wire
Bending is formed.
The invention has the beneficial effects as follows：This bulb installed part is connected reliable with ball stud, while dismounting is also very convenient.
