Description

Technical Field

[0001] This utility model relates to the technical field of connection structures, and in particular to a connection corner code. Background Technology

[0002] In the rapid assembly of display stands, furniture, greenhouse frames, and various aluminum alloy frames, corner connectors need to ensure sufficient strength while enabling angle conversion and rapid locking between profiles. Traditional methods often use flat corner brackets or integral die-cast corner pieces, with two perpendicular wings attached to the profile, then secured with screws. However, this type of structure has the following common drawbacks:

[0003] Flat corner brackets can only provide 90° connections. When the frame requires multiple splicing angles such as 30°, 45°, and 135°, multiple sets of molds must be developed, leading to increased inventory and management costs. Positioning is difficult; most existing corner brackets rely solely on the clamping force of screws for fixation, lacking a pre-positioning structure for the profile. Slippage and torsion are prone to occur during on-site installation, requiring repeated calibration and resulting in low efficiency. The corner brackets are completely flush with the bottom surface of the profile, with the screw tails exposed, affecting the appearance and easily interfering with the base surface or other components, and hindering subsequent glue injection and sealing. To improve torsional resistance, conventional practices include increasing the thickness of the base plate or adding reinforcing ribs, resulting in material waste and increased weight. Simply thinning the wall thickness can lead to defects such as die-casting shrinkage cavities and warping deformation, affecting assembly accuracy.

[0004] Therefore, how to provide a connection corner code that is simple in structure, can adapt to multi-angle splicing, has built-in positioning and anti-rotation functions, and takes into account both lightweight and high strength has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a connecting corner bracket that solves the problem that existing flat corner brackets cannot locate irregular angles and are difficult to position during the installation and connection process.

[0006] Technical solution:

[0007] A connecting bracket includes a base plate, the end face of which is provided with a protruding steering block, the steering block having an inclined surface on at least one side, the steering block having a through positioning hole at the inclined surface, and the base plate having a connecting hole on one side of the steering block.

[0008] Preferably, the steering block has a downward-through cavity, and the positioning hole communicates with the cavity.

[0009] In this embodiment, the cavity makes the steering block form a thin-walled shell, saving material and ensuring uniform wall thickness and no shrinkage cavities during die casting; the positioning hole is connected to the cavity, and the tail of the locking part can be suspended in the cavity, avoiding interference caused by protruding from the lower end face of the base plate. No additional countersunk machining is required on site, and it is also convenient for subsequent glue injection sealing or collection of drill chips, keeping the installation surface clean.

[0010] Preferably, at least two connection holes are provided, and several connection holes are symmetrically arranged on both sides of the steering block.

[0011] Preferably, the base plate has a lifting strip on the end face opposite to the steering block, and the lifting strip is located at the edge of the base plate.

[0012] In this embodiment, the lifting strip raises the main body of the base plate away from the foundation surface, forming an elevated layer. This can hide the screw tails, wiring, or inject waterproof adhesive, preventing the screw heads from scratching the ground or exposing rust. At the same time, the elevated structure provides elastic deformation margin. When the contact surface is uneven, the slight deflection of the lifting strip can still keep the base plate in contact with the profile, improving environmental adaptability.

[0013] Preferably, the base plate is also provided with feet, which are fixed to the lifting strip and are located on the side of the base plate near the positioning hole.

[0014] Preferably, the length of the foot is much shorter than that of the lifting bar, and there are two feet, which are located at the two ends of the lifting bar respectively.

[0015] In this embodiment, the short feet at both ends form a "two-point support" rather than a full-line support, while the middle section remains open, allowing workers' fingers or glue guns to easily reach in, increasing the operating space. The two-point support also ensures that corner pieces of the same batch are automatically aligned when stacked, preventing misalignment and slippage, thus improving the efficiency of on-site counting and retrieval.

[0016] Preferably, the base plate has a pair of connecting holes on each side of the steering block, and a partition strip is provided between the two connecting holes on the same side of the base plate, the partition strip being located on the side of the base plate away from the steering block.

[0017] Preferably, the connecting bracket is made of zinc alloy die casting.

[0018] Beneficial effects: The combination of the bevel and the positioning hole allows the locking component to enter the profile cavity in a non-perpendicular direction, achieving the dual functions of "angular positioning + anti-rotation". This solves the problem of loosening and misalignment of traditional corner brackets when splicing at bevels or angles. At the same time, the angle control of the bevel can adapt to the angle changes of the connectors at both ends of the corner bracket, providing better adaptability. In addition, only one drilling is needed to complete the limiting in two directions, improving installation efficiency. When connecting wall panels and base plates through the connecting corner brackets, they can be quickly positioned and quickly fixed with screws, saving time and effort during installation. Furthermore, the connecting corner brackets can be repeatedly disassembled and reused, switching to different connection positions, making them convenient and highly flexible to use.

[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides a connecting angle bracket, which is composed of a base plate 11 and a steering block 12 integrally protruding from the upper surface of the base plate 11. The base plate 11 has opposing upper and lower end faces and side walls surrounding it. The upper end face is an installation reference surface that fits with external components, and the lower end face is a support surface that contacts the base surface.

[0025] The steering block 12 extends upward from the upper end of the base plate, and its outer perimeter can be designed as a rectangle, trapezoid, or chamfered irregular shape as needed, but at least one inclined surface 13 is reserved for changing the connection direction.

[0026] In this application, the steering block 12 is provided with two symmetrical inclined surfaces 13.

[0027] The inclined surface 13 forms an angle with the upper end face of the base plate 11. The angle can be freely selected between 30° and 150° to accommodate profile splicing at different angles. The angle between the two profiles is controlled by the angle of the inclined surface.

[0028] Furthermore, the connecting corner brackets are not only used to connect two profiles, but also to connect the base plate and the wall panel, enabling rapid positioning.

[0029] A positioning hole 14 is provided at the inclined surface 13. The axis of the positioning hole 14 is perpendicular to the inclined surface 13 and passes through the steering block 12, so that the locking part can enter the cavity of the outer profile along the inclined direction during installation, thereby achieving angular positioning and anti-rotation.

[0030] like Figure 2 As shown, the steering block 12 further includes a downward-opening cavity 16 inside. The opening of the cavity 16 is located on the lower end face of the base plate 11, making the steering block 12 a thin-walled shell structure. The cavity 16 not only saves material and reduces weight, but also reduces defects such as shrinkage cavities and deformation during die casting. The positioning hole 14 extends axially from the inclined surface 13 into the cavity 16 and communicates with the cavity 16. This allows the tail of the locking component to extend out of the cavity after it is inserted, avoiding interference with the lower end face of the base plate 11. It also facilitates the collection of machining debris or the injection of anti-corrosion adhesive.

[0031] The base plate 11 has a connecting hole 15 on the side of the steering block 12. The connecting hole 15 extends along the thickness direction of the base plate 11 and is used to insert screws, rivets or expansion pins to fasten the base plate 11 to the adjacent components.

[0032] Furthermore, at least two connecting holes 15 are symmetrically arranged along the longitudinal centerline of the base plate 11. Each connecting hole 15 is located on the left and right sides of the turning block 12. By setting them in pairs, the connecting corner bracket and the profile form a double-point fixation, which significantly improves the torsional and shear resistance.

[0033] The connecting hole 15 can be designed as a countersunk stepped hole so that the screw head can be fully recessed to ensure a flat mounting surface; or it can be designed as an oblong hole to provide a certain adjustment margin to compensate for profile processing errors.

[0034] A lifting strip 17 is integrally formed on the lower end face of the base plate 11. The lifting strip 17 is formed into a non-closed convex rib shape around the edge of the base plate 11. In this application, the lifting strip 17 is only provided on the length side of the base plate 11. The lower end face of the lifting strip 17 serves as a new support surface, creating a frame space gap between the main body of the base plate 11 and the foundation surface. This gap can be used to hide the tail of the connector, run wires, apply adhesive, or form a ventilation and drainage channel, while avoiding installation warping caused by uneven foundation surface. The cross-section of the lifting strip 17 can be made into a rectangle, trapezoid, or rounded arch, and its height can be flexibly set according to actual strength and space requirements.

[0035] like Figure 2As shown, the two ends or the middle section of the lifting strip 17 are further integrally extended with floor feet 18. The height by which the floor feet 18 protrude downward is less than that of the lifting strip 17, but they have higher local compressive strength and are used to bear the self-weight of the angle code during transportation, stacking or on-site pre-assembly, preventing the lower end face of the bottom plate 11 from being scratched or polluted. The outer shape of the floor feet 18 can be short-columnar, frustum-shaped or hemispherical, and the root thereof is in arc transition with the lifting strip to avoid stress concentration. The floor feet 18 are arranged on one side of the bottom plate 11 close to the positioning holes 14 and can provide auxiliary fulcrums when the angle code is stressed obliquely, reducing the risk of warping of the bottom plate.

[0036] In this embodiment, two floor feet 18 are provided along the length direction of the lifting strip 17 and are respectively located at both ends of the lifting strip 17. The total length of the floor feet 18 is much less than that of the lifting strip 17, keeping the middle section open, facilitating the insertion of tools for operation, and also being conducive to glue injection or drainage. The short floor feet 18 at both ends form "two-point support", preventing the angle code from shaking during stacking and ensuring that the products of the same batch are stacked neatly.

[0037] Among them, a pair of connection holes 15 are provided on each side of the bottom plate 11 of the steering block 12, and there is a gap between the two connection holes 15 on the same side. A partition strip 19 is integrally formed on the lower end face of this gap area. The partition strip intersects or is parallel to the lifting strip, forming a "day" - shaped or "field" - shaped bottom grid. The partition strip 19 not only improves the local stiffness of the bottom plate, but also serves as a positioning shoulder during assembly, abuts against the inner wall of the cavity of the profile, preventing the angle code from slipping in the width direction. The lower end face of the partition strip 19 is coplanar with the lower end face of the lifting strip 17, ensuring the stable placement of the entire angle code.

[0038] The entire connecting angle code is formed by die - casting zinc alloy in one step. Zinc alloy has good fluidity and dimensional stability, and can accurately reproduce details such as the inclined plane 13, cavity 16, positioning holes 14 of the steering block, and various ribs, floor feet 18, partition strips 19 on the bottom plate 11, etc. After forming, through simple deburring, shot peening, passivation or powder spraying treatment, relatively high surface quality and corrosion resistance can be obtained, meeting the rapid installation requirements of various scenarios such as furniture, exhibition stands, greenhouse frames, etc.

[0039] When connecting the bottom plate and the wall panel through the connecting angle code, first abut the bottom plate of the connecting angle code against the bottom plate, pass the bolt through the connecting hole 15 and lock it with the bottom plate. When the wall panel is connected to the bottom plate, the wall panel abuts against the inclined plane 13, and at the same time, the bolt passes through the positioning hole 14 and the cavity 16 to be connected with the bottom plate, and the bolt also passes through the wall panel to achieve the fixed connection between the bottom plate and the wall panel.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
