Abstract

A vertical insert element with a U-shaped cross section is composed of a bottom surface and two vertical edges (1), which is characterized in that both the two vertical edges (1) are equipped with a plurality of anti-loosing chamfered angles (4) arranged in central symmetry, two ends of each vertical edge are respectively equipped with a guide angle (3) with the bottom surface and the vertical edges slightly bent inwards, two positioning holes (2) are arranged at the center of the bottom surface, and two edges of the bottom surface close to the vertical edges are respectively provided with a groove (5) which is convex to the inner bottom surface. The vertical insert element can be applied to the hollow inner connection among aluminum bars, which is easy to be inserted in but hard to be pulled out, has simple operation, firm connection and sound sealing property. After connection, the outside of the aluminum bars are nearly non-marked, the defect that the sealing property of hollow products can be affected when plastic corner elements are utilized to connect the aluminum bars is avoided, and the connected aluminum bars look attractive and beautiful. Because two hollow aluminum bars can be integrally connected via the connection element, waste of residual material of the aluminum bars can be reduced by 6%-10%.

Description

Straight cutting spare

Technical field

The utility model relates to a kind of straight cutting spare.

Background technology

The hollow aluminum strip is one of main material in the energy-conservation hollow glass, and molecular sieve desiccant is put in inside, and the hollow glass sealed space is kept dry.But the junction of aluminum strip corner was formed by connecting with the plastics corner fittings when used hollow aluminum strip was made shaped as frame at present, because the aluminum strip periphery will be tightly connected with glass, but because the shaped as frame aluminum strip is more lower slightly than other local height at the corner fittings place, cause between aluminum strip periphery and the glass and be connected and seal fully, influence the hollow product sealing performance, seem also attractive in appearance inadequately, in addition because the hollow aluminum strip requires length to fix according to model, adding to have the clout waste man-hour.For junction between the aluminum strip is not influenced and being tightly connected of glass,, need between a kind of aluminum strip of exploitation to make outside seamless substantially straight cutting spare in inner connection of hollow also in order to reduce the clout waste.

Summary of the invention

Technical problem to be solved in the utility model is: design between a kind of aluminum strip in inner connection of hollow and make the straight cutting spare that the aluminum strip outside is seamless substantially.

Technical solution of the present utility model: a kind of straight cutting spare, form by a bottom surface and two vertical edges, the cross section is the U font, it is characterized in that, a plurality of locking chamferings are respectively arranged on two vertical edges, arrangement is centrosymmetric, make it advance easily to go out difficulty when inserting the hollow aluminum strip, two respectively have the slightly guide angle of bending inwardly of a bottom surface and vertical edge, make it insert hollow aluminum strip time ratio and be easier to that there are two locating holes at the center of bottom surface, can prevent distortion and economical with materials, with the groove that a protruding bottom surface is inwards respectively arranged on close two limits, bottom surface of vertical edge, can reduce friction, also make it insert hollow aluminum strip time ratio and be easier to.A plurality of locking chamferings are preferably eight.

The utility model can be used for the inner connection of hollow between the aluminum strip, and advances easily to go out difficulty, and processing ease is connected firmly, good airproof performance, and it is seamless substantially to connect aluminum strip outside, back.Changed the plastics corner fittings and connected the deficiency that aluminum strip can influence the hollow product sealing performance, seemed also attractive in appearance beautiful,, thereby can reduce aluminum strip clout waste 6%-10% owing to two hollow aluminum strips can link into an integrated entity with connector.

The specific embodiment

A kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.

A kind of straight cutting spare, form by a bottom surface and two vertical edges 1, the cross section is the U font, it is characterized in that, eight locking chamferings 4 are respectively arranged on two vertical edges 1, arrangement is centrosymmetric, make it advance easily to go out difficulty when inserting the hollow aluminum strip, two respectively have the slightly guide angle 3 of bending inwardly of a bottom surface and vertical edge, make it insert hollow aluminum strip time ratio and be easier to that there are two locating holes 2 at the center of bottom surface, can prevent distortion and economical with materials, with the groove 5 that a protruding bottom surface is inwards respectively arranged on close two limits, bottom surface of vertical edge, can reduce friction, also make it insert hollow aluminum strip time ratio and be easier to.

Claims

1. straight cutting spare, form by a bottom surface and two vertical edges (1), the cross section is the U font, it is characterized in that, a plurality of locking chamferings (4) are respectively arranged on two vertical edges (1), the arrangement that is centrosymmetric, two respectively have the slightly guide angle (3) of bending inwardly of a bottom surface and vertical edge, there are two locating holes (2) at the center of bottom surface, with the groove (5) that a protruding bottom surface is inwards respectively arranged on close two limits, bottom surface of vertical edge.
