Description

Technical Field

[0001] The utility model belongs to the technical field of door leaf connectors, in particular to a portable angle bracket. Background Art

[0002] During the production of aluminum alloy doors and windows, the door frame and door leaf must be connected. A common method is to use an angle extrusion machine to extrude the bottom surface of the aluminum profile to form a connection with the angle bracket. Before using the angle extrusion machine, the angle bracket needs to be placed at the corner connection of the door frame. It is then connected to the door and window frame with screws, ensuring a gap-free fit between the cavity of the door and window profile, thereby increasing the strength and flatness of the door and window frame corner.

[0003] During the entire installation of the angle brackets, the angle brackets need to be manually bolted together, and the bolt hole alignment process takes a long time, resulting in low installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a portable angle code to solve the problems existing in the background technology.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A portable angle bracket includes a support frame, a spring sheet, and a self-locking mechanism. The support frame includes an inner edge, an outer edge, and a connecting edge. Two inner edges are connected at right angles, and two outer edges are also connected at right angles. The inner edges and outer edges are connected by a connecting edge. The support frame is formed into an L-shaped structure by two sets of inner edges, outer edges, and connecting edges.

[0007] The two spring sheets are respectively located on the two inner edges, the two self-locking mechanisms are respectively located on the two outer edges, the profile is provided with limiting grooves corresponding to the self-locking mechanisms, and the support frame is connected to the profile through the self-locking mechanisms and the limiting grooves.

[0008] Furthermore, the self-locking mechanism includes a limit block and a movable block, the limit block is a hollow structure, the limit block is fixed on the outer edge, the size of the limit block is adapted to the size of the limit groove, the two movable blocks are respectively located on both sides of the limit block, the movable block is telescopically connected to the limit block, and a first spring is provided between the movable block and the limit block.

[0009] Furthermore, the movable block is a wedge-shaped structure.

[0010] Furthermore, the spring sheet is a Z-shaped structure, one end of the spring sheet is fixed to the support frame, and the other end of the spring sheet is suspended, and the suspended parts of the two spring sheets correspond to each other.

[0011] Furthermore, the size of the connecting edge is adapted to the size of the cavity of the profile.

[0012] Furthermore, the support frame is an internal hollow structure.

[0013] The beneficial effects of the utility model are:

[0014] 1) The combined action of the self-locking mechanism and the spring sheet prevents the support frame from being pulled out, improving the connection effect. As the support frame is continuously inserted into the profile, the suspended side of the spring sheet is squeezed. The spring sheet's elastic force returns the support frame upward, causing the self-locking mechanism to press against the inner wall of the profile cavity until the self-locking mechanism is inserted into the limit slot, at which point the self-locking mechanism extends out of the profile through the limit slot.

[0015] 2) Reduce bolt connections and improve installation efficiency. Due to the presence of spring plates, limit slots, and self-locking mechanisms, the angle brackets can be connected to the profile by simply inserting the support frame into the appropriate position.

[0021] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0022] See Figures 1-4 , the utility model provides a technical solution:

[0023] like Figures 1-4As shown, a portable angle bracket is used for connecting profiles 4, including a support frame 1, a spring sheet 2 and a self-locking mechanism 3. The support frame 1 includes an inner edge 11, an outer edge 12 and a connecting edge 13. The two inner edges 11 are connected at right angles, and the two outer edges 12 are also connected at right angles. The inner edges 11 and the outer edges 12 are connected by the connecting edge 13. The support frame 1 is surrounded by two sets of inner edges 11, outer edges 12 and connecting edges 13 to form an L-shaped structure.

[0024] The two spring sheets 2 are respectively located on the two inner edges 11, the two self-locking mechanisms 3 are respectively located on the two outer edges 12, the profile 4 is provided with a limiting groove 41 corresponding to the self-locking mechanism 3, and the support frame 1 is connected to the profile 4 through the self-locking mechanism 3 and the limiting groove 41.

[0025] Through the above technical solution, one side connecting edge 13 of the support frame 1 is inserted into the cavity of a profile 4. As the support frame 1 is inserted, the self-locking mechanism 3 on the outer edge 12 enters the cavity of the profile 4, and the spring sheet 2 on the short side also enters the cavity of the profile 4. As the support frame 1 is continuously inserted into the profile 4, the suspended side of the spring sheet 2 will be squeezed. Under the action of the elastic reset of the spring sheet 2, the support frame 1 is driven to be squeezed upward, so that the self-locking mechanism 3 is pressed against the inner wall of the cavity of the profile 4 until the self-locking mechanism 3 is inserted into the limiting groove 41. At this time, the self-locking mechanism 3 extends out of the profile 4 through the limiting groove 41. Under the joint action of the self-locking mechanism 3 and the spring sheet 2, the support frame 1 will not be pulled out, thereby improving the connection effect.

[0026] At the same time, due to the presence of the spring sheet 2, the limiting groove 41 and the self-locking mechanism 3, the connection between the angle bracket and the profile 4 can be completed by directly inserting the support frame 1 into the appropriate position, reducing bolt connections and improving installation efficiency.

[0027] Furthermore, the self-locking mechanism 3 includes a limit block 31 and a movable block 32. The limit block 31 is a hollow structure. The limit block 31 is fixed on the outer edge 12. The size of the limit block 31 is adapted to the size of the limit groove 41. The two movable blocks 32 are respectively located on both sides of the limit block 31. The movable block 32 is telescopically connected to the limit block 31. A first spring 33 is provided between the movable block 32 and the limit block 31.

[0028] Through the above technical solution, the movable block 32 extends out of the limit block 31 under the normal state of the first spring 33 until the limit block 31 is located below the limit groove 41. At this time, under the action of the lower spring sheet 2, the limit block 31 and the movable block 32 are pushed upward by the spring. Since the movable block 32 is a wedge-shaped structure, when the movable block 32 abuts the limit groove 41, the inclined surface of the movable block 32 abuts the edge of the limit groove 41, so that the movable block 32 compresses the first spring 33 under the action of the inclined surface and shrinks into the limit block 31 until the limit block 31 extends out of the limit groove 41. At this time, under the resetting action of the first spring 33, the movable block 32 extends out of the limit block 31 again and abuts against the outside of the limit groove 41 to complete the limit locking.

[0029] Furthermore, the spring piece 2 is a Z-shaped structure, one end of the spring piece 2 is fixed to the support frame 1, and the other end of the spring piece 2 is suspended, and the suspended parts of the two spring pieces 2 correspond to each other.

[0030] Through the above technical solution, the suspended end of the spring sheet 2 is away from the insertion direction of the profile 4, so that after the support frame 1 is inserted into the cavity of the profile 4, the inner wall of the profile 4 will gradually squeeze the suspended part of the spring sheet 2 until the spring sheet 2 is completely inserted into the profile 4. At this time, the elastic force of the spring sheet 2 will drive the support frame 1 to push upward, completing the cooperation between the limit block 31 and the limit groove 41.

[0031] Furthermore, the size of the connecting edge 13 is adapted to the size of the cavity of the profile 4 .

[0032] Through the above technical solution, the size of the connecting edge 13 is adapted to the size of the cavity of the profile 4. Specifically, the width of the connecting edge 13 is the same as the width of the cavity of the profile 4, and the height of the cavity of the profile 4 is greater than the height of the connecting edge 13. This is to ensure that the connecting edge 13, the limit block 31 and the spring sheet 2 can all enter the profile 4 when the support frame 1 is inserted.

[0033] Furthermore, the support frame 1 is an internal hollow structure.

[0034] Through the above technical solution, the support frame 1 is formed into an L-shaped structure by two groups of inner edges 11, outer edges 12 and connecting edges 13, and the internal hollow structure reduces weight, facilitates installation and saves costs.

It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant field.
