Description

TECHNICAL FIELD

[0001] The utility model belongs to armored door aluminium alloy clamping edge technical field, especially relate to a armored door aluminium alloy clamping edge structure. BACKGROUND

[0002] The existing armored door clamping edge strip mainly has two structures, one is no buckle strip, and the other is buckle strip (see Figure 1 and Figure 2 )。When installing the clamping edge of no buckle strip: directly use rivet or screw to fix and install the clamping edge on the side edge of door leaf or the side edge of door core, the rivet or screw is directly exposed, and the exposed rivet or screw can be seen by naked eye, so the armored door clamping edge of no buckle strip is not very beautiful. When installing the clamping edge of buckle strip, the clamping edge of buckle strip is fixed and installed on the side edge of door leaf or the side edge of door core by rivet or screw, and then the buckle strip is buckled, the buckle strip can shield the rivet or screw, and plays a role of hiding ugliness, so the armored door clamping edge of buckle strip has certain degree of beauty.

[0003] However, in the armored door clamping edge of buckle strip, the cooperation of the buckle strip and the clamping edge strip has many problems in actual use:

[0004] 1) The buckle strip and the clamping edge need to be surface sprayed or painted, and after spraying or painting, the cooperation gap between the two will become smaller, causing the buckle strip to be unable to normally clamped into the clamping edge groove, or the buckle strip to be too loose after being clamped into the clamping edge groove, forming a shaking gap between the buckle strip and the clamping edge, so that the armored door often produces abnormal sound when in use, greatly reducing the smoothness of the whole armored door.

[0005] 2) Hardware fittings (such as hinges, locks, latches, etc.) need to be installed on both sides of the door leaf clamping edge, and hardware holes need to be reserved on the clamping edge, which requires the buckle strip to be cut into several segments, and the operation and processing are complex, the error is increased, and the product beauty is also reduced. INVENTION CONTENTS

[0006] The utility model aims at overcoming the defects in the prior art, and provides a novel aluminium alloy clamping edge strip.

[0007] The novel aluminium alloy clamping edge strip comprises: a fixed clamping piece and a clamping edge strip; the clamping edge strip is a no buckle strip integral type; two symmetrical recesses and a protrusion located in the middle of the recesses are arranged on the clamping edge strip; the fixed clamping piece is clamped into the two recesses on both sides of the clamping edge strip; when the fixed clamping piece is clamped into the clamping edge strip, the protrusion on the clamping edge strip does not contact the fixed clamping piece.

[0008] As preferred: the two recesses on both sides of the card edge strip are provided with sliding-in portions, the sliding-in portions are inclined convex blocks with a certain slope (the sliding-in portions facilitate the fixed clamping piece to be easily clamped into the two recesses on both sides of the card edge strip), and the inclined convex blocks are further provided with V-shaped buckle portions in the direction of the slope.

[0009] As preferred: a gap with a certain width is formed between the protrusion on the card edge strip and the fixed clamping piece, which facilitates providing a containing space for the screw end for fixing the fixed clamping piece on the side edge of the door leaf or the side edge of the door core, and makes the appearance beautiful and the integrity strong.

[0010] As preferred: the protrusion on the card edge strip is a hollow cavity, which saves materials.

[0011] The beneficial effects of the novel aluminum alloy card edge strip structure are as follows: the novel aluminum alloy card edge strip structure cancels the card edge buckle strip and adopts the buckle-free integrated card edge strip, which is easy to process and has high integrity and beautiful appearance; the two recesses on both sides of the card edge strip are provided with sliding-in portions, which facilitate the fixed clamping piece to be easily clamped into the two recesses on both sides of the card edge strip; a gap with a certain width is formed between the protrusion on the card edge strip and the fixed clamping piece, which facilitates providing a containing space for the screw end for fixing the fixed clamping piece on the side edge of the door leaf or the side edge of the door core, and makes the appearance beautiful and the integrity strong; and the protrusion on the card edge strip is a hollow cavity, which saves materials.

[0018] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0019] As one example, such as Figures 3 to 5 As shown, a novel aluminum alloy edge strip includes: a fixing clip 4 and an edge strip 5; the edge strip 5 is an integral type without a buckle strip; the edge strip 5 has two symmetrical recesses and a protrusion 10 located in the middle of the recesses; each of the two recesses on both sides of the edge strip 5 has a sliding part 6, the sliding part 6 is a sloping protrusion with a certain slope (the sliding part facilitates the fixing clip to easily snap into the two recesses on both sides of the edge strip), the sloping protrusion has a V-shaped buckle part 8 along the downward slope direction, and the fixing clip 4 has hook-shaped parts at both ends pointing outwards. 7; The two ends of the fixing clip 4 are inserted into the two recesses on both sides of the edge strip 5. When the new aluminum alloy edge strip is installed, the V-shaped buckle part 8 and the hook-shaped part 7 interlock with each other. When the fixing clip 4 is inserted into the edge strip 5, there is a certain width gap 9 between the protrusion 10 on the edge strip 5 and the fixing clip 4, which facilitates the provision of accommodating space for the screw end used to fix the fixing clip to the side of the door leaf or the side of the door core, making the appearance beautiful and the overall structure strong. The protrusion 10 on the edge strip 5 has a hollow cavity inside, which saves materials.
