Abstract
The utility model relates to a clamping structure which comprises a buckling head installed on a first connection part and a clamping flanging matched with the buckling head and installed on a second connection part. The buckling head comprises a buckling head body and a protrusion arranged at the front end of the buckling head body, and the protrusion comprises a first inclined surface and a second inclined surface. One end of the first inclined surface, which is connected with the second inclined surface, is of an arc surface structure. The clamping structure has the advantages of effectively prolonging service life, reducing maintenance cost and improving clamping stability.
Description
Technical field
The utility model relates to a kind of interface arrangment.
Background technique
Traditional interface arrangment is for guaranteeing the validity of clamping, and the locking face is the broad of design generally, and required withdrawal force is excessive when dismounting is extracted; Make that the distortion of buckle head and clamping flange is serious, reduce effectively plug number of times, simultaneously; Because plug repeatedly; The clamping stability of interface arrangment reduces rapidly, and the after-sales service cost is high, and product quality is low.
The model utility content
To above-mentioned deficiency, the utility model provides a kind of interface arrangment.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of interface arrangment; Comprise the buckle head that is installed in first link and match with said buckle head, be installed in the clamping flange on second link; Said buckle head comprises buckle head body and the convexity that is arranged on buckle head body front end, and said convexity comprises first inclined-plane and second inclined-plane, and the end that said first inclined-plane is connected with said second inclined-plane is a globoidal structure.
Further, the angle between said first inclined-plane and the said buckle head body is 10 degree.
Further, the angle between said second inclined-plane and the said buckle head body is 65 degree.
Further, a side of said buckle head body is provided with stiffening rib.
Further, also comprise the Returnning spring rod that is arranged on said first link, said Returnning spring rod is positioned at the side that said bayonet socket head body is provided with stiffening rib.
The beneficial effect of the utility model is: effectively improve the working life of interface arrangment, reduce maintenance cost, and improve interface arrangment clamping stability.
Description of drawings
Fig. 1 representes the utility model structural representation;
Fig. 2 representes the schematic representation that is connected of buckle head body and Returnning spring rod on the utility model first link.
Reference character: 1, buckle head body, 2, the clamping flange, 3, convexity, 31, first inclined-plane, 32, second inclined-plane, 4, the Returnning spring rod.
Embodiment
Below in conjunction with accompanying drawing the utility model principle and structure are described, the embodiment that lifts only is used to explain the utility model, is not the protection domain that is used to limit the utility model.
As shown in Figure 1; A kind of interface arrangment; Comprise the buckle head that is installed in first link and match with said buckle head, be installed in the clamping flange 2 on second link; The convexity 3 that said buckle head comprises buckle head body 1 and is arranged on buckle head body 1 front end, said protruding 3 comprise first inclined-plane 31 and second inclined-plane 32, said first inclined-plane 31 is a globoidal structure with the end that said second inclined-plane 32 is connected.
In the present embodiment preferred implementation; Angle between said first inclined-plane 31 and the said buckle head body 1 is 10 degree; When first inclined-plane 31 is buckle head and the clamping of clamping flange; The locking face that contacts with clamping flange 2, this locking face be set to and buckle head body 1 between angle be first inclined-plane of 10 degree, effectively improve the lockup capacity of buckle head.
In the present embodiment optimal way, the angle between said second inclined-plane 32 and the said buckle head body 1 is 65 degree.Adopt like this when effective raising buckle head and the clamping of clamping flange are set, the clamping flange is to the power of shrinking back that buckle head produces, and it is more convenient to make buckle head insert second link at clamping flange place.
In the present embodiment, said first inclined-plane 31 is a globoidal structure with the end that said second inclined-plane 32 is connected.This globoidal structure the guidance quality that has strengthened buckle head is set, required withdrawal force when reducing buckle head and separating with the clamping flange has also effectively reduced the distortion of buckle head and clamping flange.
One side of buckle head body 1 is provided with stiffening rib 5, stiffening rib 5 be arranged on buckle head body 1 on protruding 3 the relative opposite side of a side is set, stiffening rib 5 the intensity that has strengthened buckle head is set.
As shown in Figure 2; Interface arrangment also comprises the Returnning spring rod 4 that is arranged on said first link in the present embodiment; Returnning spring rod 4 is positioned at the side that buckle head body 1 is provided with stiffening rib 5; And be provided with the gap between Returnning spring rod 4 and the stiffening rib 5, effectively avoid also having prevented owing to the situation of repeatedly using the flexible distortion of buckle head body that causes because the clamping that the end that first inclined-plane 31 is connected with second inclined-plane 32 is a globoidal structure to be caused is unstable.
The diameter of Returnning spring rod 4 is 0.8-1.5mm in the present embodiment, and in the present embodiment optimal way, the diameter of Returnning spring rod 4 is 1.5mm, and the gap between Returnning spring rod 4 and the stiffening rib 5 is 0.2mm-0.5mm.
Adopt the utility model interface arrangment, effectively the plug number of times with first link and second link is enhanced about more than once, and reduces maintenance cost, improves the clamping stability of interface arrangment simultaneously.
The above is the utility model preferred embodiment, is not to limit the utility model institute protection domain with this, and is all within the utility model spirit and principle, the modification of being done, is equal to replacement etc., all should be included within the utility model protection domain.
