Description

Technical Field

[0001] The utility model relates to the technical field of angle codes, and more specifically to a three-digit angle code. Background Art

[0002] Three-way angle brackets are a common structural connection element used to connect different parts of objects, such as wood, metal or plastic. They are usually used with pillars, frames or other structural components through screws, bolts or other connectors. Three-way angle brackets are suitable for corner connections. They provide a way to form a strong connection at the corner and are often used to ensure that the structure remains balanced and stable when subjected to force.

[0003] In the current market, some wooden furniture usually needs to be strengthened at the corners. Several L-shaped corner brackets are connected by bolts to achieve a strong connection at the corners. However, there are still problems such as inconvenient installation and insufficient structural strength and stability. Some three-dimensional corner brackets currently on the market use self-tapping screws to drive into wooden profiles, but there are still problems such as insufficient connection structure strength, easy cracking of wooden profiles after being driven in, and unstable profile structure.

[0006] The utility model is further configured as follows: the fixed cone is configured as a triangular block with a sharp top, and the fixed cone is fixedly connected to the contact surface; a plurality of fixed particles are fixedly connected to the contact surface to increase the contact area between the contact surface and the profile.

[0007] The utility model is further configured as follows: a plurality of reinforcing ribs are arranged between the L-shaped pieces, one end of the reinforcing ribs is connected to the semicircular wing, and the other end is connected to the square wing with rounded corners.

[0008] The utility model is further configured as follows: the connecting angle bracket is integrally die-cast.

[0009] The utility model is further configured as follows: the reinforcing rib is welded and matched with the L-shaped piece.

[0010] In summary, the utility model has the following beneficial effects:

[0011] 1. The staggered arrangement of the semicircular wings and the square wings with rounded corners helps to provide a more uniform force distribution around the connection points. On the premise of ensuring the structural strength, the lightweight design provides a richer appearance effect and aesthetic value. The presence of the fixing cone can provide additional support for the area after the self-tapping screws are driven into the profile, provide a reaction force for the squeezed wood, and increase the stability of the profile.

[0012] 2. The fixing cone is set as a triangle with a sharp top, which provides a stronger anchoring force, helps to embed deeper into the profile, and provides more reliable stability; a number of fixing particles are fixedly connected on the contact surface, which helps to increase the contact area between the contact surface and the profile, provide greater surface friction, and thus enhance the stability of the connection.

[0013] 3. The connecting angle bracket is integrally die-cast, which can improve the overall strength and stability of the structure and reduce potential weaknesses caused by the interfaces between the connecting parts. Several reinforcing ribs are set between the L-shaped pieces to further strengthen the structure of the L-shaped pieces, improve the rigidity and strength of the overall connecting angle bracket, and connect the two different parts of the flanks of different shapes at the same time, which helps to balance the force and provide more uniform support. Through welding, the integrity of the structure is improved and the force transmission effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] This embodiment discloses a three-digit angle code, such as Figure 1-3 As shown, a three-dimensional angle code includes a connecting angle code 1, and the connecting angle code includes three L-shaped pieces 2. The L-shaped pieces 2 include semicircular wings 21 and square wings with rounded corners 22. The semicircular wings 21 and the square wings with rounded corners 22 are arranged alternately; this design can provide a more uniform force distribution around the connection point, the curved shape of the semicircular wings 21 helps to reduce stress concentration, and the square wings with rounded corners 22 can provide a larger connection area; the staggered arrangement helps to achieve a wide range of applications in different usage environments. For example, when a higher strength support is required in a certain direction, the three-dimensional angle code can be rotated so that the strength and structure are set accordingly; this design achieves the goal of lightweight while ensuring strength; a longitudinally penetrating conical limiting hole 3 is provided on each surface of the L-shaped piece 2, The connecting angle code 1 is connected and fixed to the external profile by inserting a self-tapping screw through the conical limiting hole 3; the surface of the L-shaped piece 2 in contact with the profile is set as a contact surface 23, and a positioning groove 32 is concentrically arranged at the conical limiting hole 3 on the contact surface 23 of the semicircular wing 21, and a gasket 33 is arranged in the positioning groove 32. A number of fixing cones 31 are arranged around the conical limiting hole 3 on the gasket 33. After the self-tapping screw is driven into the profile, the profile is squeezed to the surroundings by the self-tapping screw. After the fixing cone 31 is embedded in the profile, the profile is affected by its resistance, which provides a reaction force for the wood squeezed open by the self-tapping screw, prevents the area from cracking, provides additional support, and provides certain compensation for the penetrated area, so that the structure is more stable and not easy to crack; the fixing cone 31 is used to stabilize the profile to make the structure of the profile stable.

[0021] The fixed cone 31 is configured as a triangular block with a sharp top, and the fixed cone 31 is fixedly connected to the contact surface 23; the fixed connection makes the fixed cone 31 firmly connected to the contact surface of the connecting angle code 1, which can provide a more solid and stable overall structure; a number of fixed particles 231 are fixedly connected to the contact surface 23, which are used to increase the contact area between the contact surface 23 and the profile, provide greater surface friction, and thus enhance the stability of the connection.

[0022] A number of reinforcing ribs 4 are arranged between the L-shaped pieces 2, one end of the reinforcing rib 4 is connected to the semicircular wing 21, and the other end is connected to the square wing with rounded corners 22. This design further strengthens the structure of the L-shaped piece 2 and improves the rigidity and strength of the overall connecting angle code 1; the reinforcing rib 4 is connected to two different parts of the semicircular wing 21 and the square wing with rounded corners 22, which helps to balance the force and provide more uniform support.

[0023] The connecting angle code 1 is integrally stamped and formed, which improves the overall strength and stability of the structure and reduces potential weaknesses caused by interfaces between connecting parts.

[0024] The reinforcing rib 4 is welded to the L-shaped piece 2, which improves the strength between the reinforcing rib and the L-shaped piece, improves the durability of the connecting angle code 1, and achieves better force transmission and structural integrity of the connecting angle code 1.
