Description
Technical field
The utility model relates to automobile component structures, and in particular to a kind of automobile external opening handle bolt pre-installation structure.
Background technique
Automobile external opening handle is made from multiple components, and is all to be attached between component and component using bolt, still
Different components has different producting factories to be made more, then pools together and assembled.In order to improve packaging efficiency, lead to
The pre-installation that bolt can be often carried out on corresponding component, is exactly fixed on respective bolt installation through-hole for the screw rod of pre- cartridge screw
In, while ensuring that the screw rod end of pre- cartridge screw is located in bolt installation through-hole again and causing to interfere to avoid to installing component.
After pre- cartridge screw on adjacent component is aligned with screw hole, directly the screw being pre-installed is twisted.At present to prepackage
The mode that screw is fixed is to use the interference fit of screw rod in entire bolt installation through-hole and pre- cartridge screw, but pre-installing
In the process, the screw rod of pre- cartridge screw is inserted into bolt installation through-hole from the beginning, to being inserted in the deeper depth of bolt installation through-hole,
Interference fit increases the screw rod installation difficulty of pre- cartridge screw, needs to apply bigger active force, increases pre-assembled operational worker
Work load.
Utility model content
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot
Structure is simple, and easily reliable automobile external opening handle bolt pre-installs structure to pre-assembled operational.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of automobile external opening handle bolt pre-installation structure, including plastic handles bracket and pre- cartridge screw, plastic handles branch
Bolt installation through-hole is offered on frame, the screw rod of pre- cartridge screw is inserted in bolt installation by the outboard end of bolt installation through-hole and leads to
In hole, the screw clearance of bolt installation through-hole and pre- cartridge screw cooperates, on bolt installation through-hole and the hole wall at end on its inside
A plurality of bar shaped fin is convexed to form around its uniform intervals using bolt mounting holes center line as the center of circle, bar shaped fin is installed by bolt
The inner end port position of through-hole extends along bolt installation through-hole length direction, and the length of bar shaped fin is less than bolt installation through-hole
The length of one third is formed with the inside limit hole that the screw rod of pre- cartridge screw can be made to pass through between a plurality of bar shaped fin, in advance
The screw rod of cartridge screw is inserted in internal limit hole and is interference fitted with it, plastic handles bracket and is located at outside bolt installation through-hole
A plurality of positive stop strip has been convexed to form around its uniform intervals using the center line of bolt installation through-hole as the center of circle on the surface of side, it is a plurality of
Positive stop strip is located at the outside on the head of pre- cartridge screw, and the head of pre- cartridge screw can be along bolt installation through-hole centerline direction and limit
Position item is slidably matched, and position limiting structure is provided on an at least positive stop strip, and position limiting structure includes convexing to form in positive stop strip
The head of outer baffle block on side, pre- cartridge screw can be by the flexible deformation of positive stop strip where outer baffle block, so that pre- cartridge screw
Head can the side from outer baffle block far from plastic handles bracket outer baffle block is entered toward plastic handles by outer baffle block
The side of bracket, the head of pre- cartridge screw are connected to outer baffle block toward on the side side of plastic handles bracket.
In the present invention, bar shaped fin is only arranged in entire bolt installation through-hole at the hole wall of its inner end, in this way
It is interference fitted a small amount of position in screw rod end of pre- cartridge screw with internal limit hole；Since the screw rod of pre- cartridge screw is opposite
Fixed stability is poor, and a plurality of limit inside it is wrapped on the head of pre- cartridge screw in the lateral surface setting of plastic handles bracket
Position item makes pre- cartridge screw be only capable of enough being moved along bolt installation through-hole centerline direction；Recycle the limit knot on positive stop strip
Structure limits the head of pre- cartridge screw, and pre- cartridge screw is avoided to exit bolt installation through-hole, that is, completes the prepackage work of screw
Make.So operator only needs the screw rod for making pre- cartridge screw and a small amount of interference installation of bolt installation through-hole to can be completed to pre-
The fixation of cartridge screw not only alleviates the work load of operator, while its structure is simple, and pre-assembled operational is easily reliable, also
It improves work efficiency.
As optimization, the position limiting structure further includes the internal stop convexed to form on the positive stop strip medial surface, interior gear
Block is located at the outer baffle block where it on described positive stop strip and sets toward the side of the plastic handles bracket and being separated by with it
It sets, internal stop is connected to the head of the pre- cartridge screw toward on the side side of the plastic handles bracket, the prepackage
It the head of screw can be by the flexible deformation of the positive stop strip described where internal stop, so that the head of the pre- cartridge screw can be from
Side of the internal stop far from the plastic handles bracket enters internal stop toward the plastic handles bracket by internal stop
Side.Internal stop can limit the head of pre- cartridge screw, and the screw rod of pre- cartridge screw during prepackage is avoided to stretch out
It causes to interfere in installing subsequent component outside internal limit hole.
As optimization, the outer baffle block and the internal stop are right angle trigonometry block, a right-angle surface court of right angle trigonometry block
To in plastic handles bracket side and with the centerline direction of the bolt installation through-hole it is perpendicular, right angle trigonometry block it is oblique
Opening side is formed by facing towards surrounding in a plurality of positive stop strip.The head of pre- cartridge screw acts on the oblique of right angle trigonometry block
On face, by the decomposition of force direction, it can make positive stop strip outer under natural resiliency deformability, conveniently make pre- cartridge screw
Head pass through.
As optimization, the quantity of the positive stop strip is four, is provided with limit on any two opposite positive stop strips
Structure, the outer baffle block is located at the one end of the positive stop strip far from the plastic handles bracket where it, described in remaining two
The medial surface of the respective one end far from the plastic handles bracket of positive stop strip is provided with guide surface, guide surface and the right angle three
The inclined-plane of hornblock matches so that a plurality of positive stop strip surrounds the opening for being formed by opening to extend out.The opening extended out is convenient
The head of pre- cartridge screw is led into, makes to pre-install more convenient.
In conclusion pre-assembled operational easily may be used the utility model has the beneficial effects that: the utility model structure is simple
It leans on, not only alleviates the work load of operator, also improve working efficiency.
