Description
Technical field
The utility model belongs to parts assembly field, and in particular to a kind of fastener assembling structure up and down.
Background technique
Currently, upper fastener and lower fastener generally pass through insertion manner assembly.When being assembled, due to upper fastening
The gravity of part, therefore generally require the position that upper fastener is controlled using fixture, so as to by upper fastener and lower fastener
Accurate contraposition connection.Such as: when upper fastener and lower fastener in passenger-car chassis class product weld, usually utilize welding fixture
Upper fastener and lower fastener are fixed, according to the fastening degree of upper and lower fastener to guarantee its relative position.But pass through folder
Tool controls the position of upper fastener, tends not to the relative position for guaranteeing upper fastener and lower fastener very well, influences fastening
The performance of product after the welding quality and welding of part and lower fastener.
Utility model content
It can be good at guaranteeing upper fastener and lower fastener the technical problem to be solved by the present invention is to provide one kind
Relative position fastener assembling structure up and down.
The technical scheme adopted by the utility model to solve the technical problem is as follows: upper and lower fastener assembling structure, including it is upper
Fastener and lower fastener, the upper fastener include the first upper side edge and the second upper side edge, and the lower fastener includes first
Lower side and the second lower side；The lateral surface of first upper side edge is equipped with upper limit portion, the outside of second lower side
Face is equipped with lower limit portion；The upper fastener and the dislocation of lower fastener fasten, the lateral surface and first of first upper side edge
The medial surface of lower side is affixed, and the upper end of the first lower side is affixed with upper limit portion；The lateral surface of second lower side with
The medial surface of second upper side edge is affixed, and the lower end of the second upper side edge is affixed with lower limit portion.
Further, the upper limit portion at least two, and be spaced apart along the length direction of the first upper side edge；Institute
Lower limit portion at least two is stated, and is spaced apart along the length direction of the second lower side.
Further, lateral surface of the outer edge in the upper limit portion without departing from the first lower side；The lower limit portion
Outer edge without departing from the second upper side edge lateral surface.
Further, the upper fastener welds together with lower fastener.
The beneficial effects of the utility model are: by the way that upper limit portion is arranged on the lateral surface of the first upper side edge, and the
Lower limit portion is set on the lateral surface of two lower sides, after upper fastener and the dislocation of lower fastener are fastened, i.e., using under first
Side is supported upper limit portion, and is supported using lower limit portion to the second upper side edge, to just can be good at protecting
The relative position of fastener and lower fastener on card does not need that complicated fixture is recycled to be positioned.Because of upper fastener
Stablize with the relative position of lower fastener, can effectively avoid being partially welded when being welded, burn phenomena such as lacking, so that welding quality
And welding after product performance it is more stable.
Detailed description of the invention
Fig. 1 is the three dimensional structure diagram that the utility model overlooks visual angle；
Fig. 2 is the cross-sectional view of the line A-A along Fig. 1；
Fig. 3 is the three dimensional structure diagram that the utility model looks up visual angle；
In the figure, it is marked as upper fastener 100, the first upper side edge 110, upper limit portion 111, the second upper side edge 120, lower fastening
Part 200, the first lower side 210, the second lower side 220, lower limit portion 221.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, upper and lower fastener assembling structure, including upper fastener 100 and lower fastener 200,
Upper fastener 100 includes the first upper side edge 110 and the second upper side edge 120, and lower fastener 200 includes the first lower side 210 and the
Two lower sides 220；The lateral surface of first upper side edge 110 is equipped with upper limit portion 111, sets on the lateral surface of the second lower side 220
There is lower limit portion 221；Upper fastener 100 and the dislocation of lower fastener 200 fasten, under the lateral surface and first of the first upper side edge 110
The medial surface of side 210 is affixed, and the upper end of the first lower side 210 is affixed with upper limit portion 111；Outside second lower side 220
Side and the medial surface of the second upper side edge 120 are affixed, and the lower end of the second upper side edge 120 is affixed with lower limit portion 221.
Wherein, upper limit portion 111 and lower limit portion 221 are respectively to be arranged in the first upper side edge 110 and the second lower side 220
On position limiting structure, upper limit portion 111 and lower limit portion 221 are usually boss structure, and boss structure can be various shapes, example
Such as: triangle, rectangle, polyhedron shape；Generally, upper limit portion 111 has lower end limited support face, lower limit portion 221
With upper end limited support face；Upper limit portion 111 is preferably the support rim of a quarter elliposoidal shown in Fig. 2, should
Biggish plane is combined with the first upper side edge 110 on support rim, and lesser plane is as lower end limited support face；Similarly, under
Limiting section 221 is preferably also the support rim of a quarter elliposoidal.
In order to guarantee the aesthetics and practicability of the product shape after upper fastener 100 and the assembly of lower fastener 200, usually
Make the outer edge in upper limit portion 111 without departing from the lateral surface of the first lower side 210, make the outer edge in lower limit portion 221 without departing from
The lateral surface of second upper side edge 120.
In order to reach better limited support effect, it is preferred that upper limit portion 111 at least two, and along the first upside
The length direction on side 110 is spaced apart；Lower limit portion 221 at least two, and along the length direction interval of the second lower side 220
Distribution.
After upper fastener 100 and lower 200 accurate contraposition of fastener, it is generally welded together.Since upper limit portion 111 is under
The limited support of limiting section 221, therefore the relative position of upper fastener 100 and lower fastener 200 is stablized, it can when being welded
It effectively avoids being partially welded, burn phenomena such as lacking, so that the performance of product is more stable after welding quality and welding.
