Description

A connecting corner code with an empty slot in the middle

technical field

The utility model relates to the technical field of connection accessories, in particular to a corner code that can be used in construction engineering, decoration engineering, furniture and other fields.

Background technique

Corner bracket is a connection fitting widely used in construction engineering, decoration engineering, furniture and other fields. It is usually a right-angle structure, that is, an L-shaped structure. Of course, it can also be made into a required angle according to needs. The current corner code generally includes a first connecting arm (horizontal arm) and a second connecting arm (vertical arm) forming an L-shaped structure, and the parts to be connected are respectively fixed on the first connecting arm and the second connecting arm, such as For the fixing of aluminum profiles for windows. However, the fixed structure of this traditional corner bracket has the following disadvantages. First, the profiles on both sides are difficult to fully fit when they are docked, and there are large gaps, which are not beautiful; second, the first connecting arm and the second connecting arm The surface of the arm is a flat surface. When glued and fixed, the glue is coated on the surface. Since the profile and the corner bracket are relatively close in structure, when the first connecting arm and the second connecting arm are inserted into the profile, Plastic corner code scraps and glue will overflow due to friction and accumulate at the joint, forming a large assembly gap, affecting the assembly tightness, or overflowing on the surface of the profile, affecting the appearance, and making cleaning difficult. Third, the use of screws is not beautiful enough , but simply using glue is not strong enough, and it is easier to fall off after a long time.

Utility model content

The technical problem to be solved by the utility model is to provide a connection angle bracket with a space-avoiding groove in the middle with a more reasonable structural design, a more stable connection, a more fitting assembly, and a more beautiful exterior.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: a connecting angle bracket with an escape groove in the middle, including a first connecting arm and a second connecting arm connected into a corner bracket structure, and is characterized in that: A connecting arm and the second connecting arm are provided with a supplementary strip protruding from the surface of the corner code, and the supplementary strip separates the first connecting arm and the second connecting arm to form a pair of sockets on the first connecting arm. Complementary structure for profiles on the arm and the second connecting arm; a space-avoiding groove is provided on both sides of the filling strip, and the space-avoiding groove is recessed downward from the surfaces of the first connecting arm and the second connecting arm.

Further, the supplementary strip extends from the outer corner of the connecting part of the first connecting arm and the second connecting arm to the inner corner, and the supplementary strip also protrudes from the bottom surface of the corner code, and the surface and bottom surface of the supplementary strip and both sides are planar structures, and after the profile is fixed on the first connecting arm and the second connecting arm, its surface and bottom are respectively flush with the surface and bottom of the filling strip, forming a smooth transition.

Further, the space-avoiding groove is close to both sides of the supplementary strip, and its width is smaller than the width of the supplementary strip, and the two ends of the space-avoiding groove directly pass through the inner and outer sides of the corner code to form an open groove structure, avoiding the space The glue that cannot be stored in the groove can also flow down through the openings on both sides to avoid overflowing to the surface of the profile.

Further, the end of the first connecting arm is provided with a groove connecting part, and the end of the second connecting arm is also provided with a groove connecting part, and the two groove connecting parts are provided with grooves alternately concave and convex structure. Through the adhesive groove design, the friction force of the corner code can be increased, so that the corner code and the profile can form a more firm connection.

Further, one or both of the first connecting arm and the second connecting arm are provided with snap buttons for assisting in fixing the profile, and the snap buttons protrude from the surface or bottom of the corner bracket.

Further, the snap button is located on a snap arm to form an elastic structure, and the snap arm is connected to the first connecting arm or the second connecting arm. A fixing hole matching the snap button is set on the profile. After the profile is pushed into place, the snap button is automatically snapped into the fixing hole under the action of the snap arm to form a more stable fixing structure.

Preferably, the first connecting arm, the second connecting arm, the snap button, the snap button arm and the replacement strip are integrally formed and made of plastic material, rubber material or polymer composite material, which can be selected according to different needs.

The utility model can make the profiles on both sides seamlessly docked by setting the supplementary strips on the corners, which is more beautiful. Overflow, piled up at the joint, forming a large assembly gap, affecting the assembly tightness, or overflowing on the surface of the profile, affecting the appearance, and making it difficult to clean; and designing groove joints at both ends of the corner code can improve friction The cohesiveness of the glue and the glue, so that the profiles can form a more stable connection.
