Description

Technical Field

[0001] This utility model relates to the field of snap-fit ​​connectors, specifically a planar snap-fit ​​connector. Background Technology

[0002] Snap-fit ​​connectors are fastening devices that achieve rapid assembly through a mechanical interlocking structure. Flat snap-fit ​​connectors are widely used in building decoration and light steel keel systems. Traditional flat snap-fit ​​connectors have two connecting blocks orthogonally distributed at 90°, respectively fitting against the vertical and horizontal planes of the keel, and are fixed using snaps or bolts. This orthogonal structure results in a large overall size for the connector, making installation difficult in confined spaces, and the protruding part can easily interfere with other pipelines. Furthermore, the connector requires bolts and nuts for final fixation during installation, which is costly and increases the number of installation steps.

[0003] Therefore, it is necessary to design a flat snap-fit ​​connector that is practical, easy to install, and reduces costs. Utility Model Content

[0004] The purpose of this utility model is to provide a planar snap-fit ​​connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a planar snap-fit ​​connector, comprising a first connecting block and a second connecting block, wherein the first connecting block is a long block and the second connecting block is a short block, and the first connecting block and the second connecting block are stacked to form a receiving cavity, a guide mechanism is provided on one side of the first connecting block and the second connecting block, a slot is provided inside the first connecting block, a circular groove is provided inside the second connecting block, a tension ring is connected to one side of the circular groove, a thread is provided on the inner side of the tension ring, a bolt is correspondingly provided inside the tension ring, a reinforcing rib is provided on one side of the second connecting block, a bent block is provided on the side of the first connecting block, and an inclined block is provided on the side of the second connecting block.

[0006] According to the above technical solution, the height of the tension ring is 2-3mm.

[0007] According to the above technical solution, a lightweight keel is placed inside the receiving cavity, and the curved block and the inclined block are respectively fitted with the concave part of the lightweight keel.

[0008] According to the above technical solution, the gap between the bolt and the lightweight keel is 0.5mm.

[0009] According to the above technical solution, the slot is elliptical and corresponds to the bolt.

[0010] According to the above technical solution, the guiding mechanism includes a V-shaped block, which is disposed on one side of the first connecting block and the second connecting block.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By setting two straight connecting blocks, the keel can be fixed by simply attaching to one side of the keel after being stacked. Compared with the traditional vertical buckle structure that needs to wrap multiple sides of the keel, the overall thickness is reduced and the space occupied is significantly reduced.

[0013] (2) By setting a tension ring, the tension ring and the bolt threaded together, only one bolt needs to be tightened to complete the fixation, without the need for additional nuts or other fasteners, which simplifies the installation steps, shortens the assembly time, and reduces labor costs;

[0014] (3) By setting V-shaped blocks, the first connecting block and the second connecting block are quickly overlapped and aligned, simplifying the assembly process. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4The present invention provides a technical solution: a planar snap-fit ​​connector, comprising a first connecting block 1 and a second connecting block 2, wherein the first connecting block 1 is a long block and the second connecting block 2 is a short block, and the first connecting block 1 and the second connecting block 2 are stacked to form a receiving cavity. A guide mechanism is provided on one side of the first connecting block 1 and the second connecting block 2. A slot 7 is provided inside the first connecting block 1 and a circular groove 6 is provided inside the second connecting block 2. A tension ring 5 is connected to one side of the circular groove 6. A thread is provided on the inner side of the tension ring 5. A bolt 4 is provided inside the tension ring 5. A reinforcing rib 3 is provided on one side of the second connecting block 2. A bent block 8 is provided on the side of the first connecting block 1 and a wedge block 9 is provided on the side of the second connecting block 2.

[0022] The first connecting block 1 is elongated, and the second connecting block 2 is short. When they are stacked, they are quickly aligned by a guiding mechanism. The distance difference between the two connecting blocks forms a receiving cavity, which is used to wrap the side of the lightweight keel. The first connecting block 1 has a bent block 8 on its side, and the second connecting block 2 has an inclined block 9 on its side. The bent block 8 abuts against a recess on one side of the lightweight keel, and the inclined block 9 abuts against a recess on the other side of the lightweight keel, thereby fixing them. The second connecting block 2 has a circular groove 6 inside. A hollow tension ring 5 is connected to one side of the circular groove 6. The tension ring 5 has threads machined on its inner side. During assembly, the bolt 4 passes through the groove 7 and is screwed into the thread of the tension ring 5. Tightening the bolt 4 generates axial tension, causing the two connecting blocks to be tightly pressed together, thereby further fixing the lightweight keel. The second connecting block 2 has reinforcing ribs 3 on its outer side. Two reinforcing ribs 3 are distributed on both sides of the bolt 4 to improve the bending strength of the connector. With the addition of a tension ring 5, only one bolt 4 is needed for installation and fixing, eliminating the need for a nut, simplifying the installation process, shortening assembly time, and reducing labor costs. It also reduces the need for additional fasteners, lowering material costs and reducing inventory management complexity. The overlapping of two connecting blocks allows for quick and easy installation of the lightweight keel, saving manpower.

[0023] The height of the tension ring 5 is 2-3mm.

[0024] The tension ring 5 is an annular structure, integrally formed on the side of the circular groove 6 of the second connecting block 2, with standard threads machined on its inner side for engagement with the bolt 4. The tension ring 5 has a minimum length of 2mm to ensure the thread engagement length meets tensile strength requirements and prevents thread stripping; the tension ring 5 has a maximum length of 3mm to prevent material redundancy and reduce the overall weight of the connector. By incorporating the tension ring 5, no additional nuts are needed during installation, reducing the requirement for extra fasteners and lowering material costs.

[0025] The interior of the cavity contains a lightweight keel, with the curved block 8 and the inclined block 9 fitting into the concave part of the lightweight keel.

[0026] The connecting blocks are used to connect the lightweight keel. The inner contours of the bent block 8 and the inclined block 9 match the concave part of the surface of the lightweight keel, fitting and fixing the keel to prevent displacement.

[0027] The gap between bolt 4 and the lightweight keel is 0.5mm.

[0028] After bolt 4 is screwed in, there is only a 0.5mm gap between bolt 4 and the keel. This minimal gap ensures tight contact between bolt 4 and the keel, reducing displacement under vibration or load and improving connection stability. The tight fit also reduces the risk of bolt 4 loosening due to external forces, enhancing long-term reliability.

[0029] The groove 7 is elliptical and corresponds to the bolt 4.

[0030] An elliptical groove 7 is formed at the corresponding position of the first connecting block 1. The size of the groove 7 is slightly larger than the diameter of the bolt 4. The elliptical shape disperses the stress of the bolt 4's tension on the edge of the groove 7, preventing the connecting block from cracking due to localized stress. The elliptical groove 7 allows the first connecting block 1 to move horizontally relative to the second connecting block 2, solving the alignment misalignment problem between the two connecting blocks and the keel.

[0031] The guiding mechanism includes a V-block, which is located on one side of the first connecting block 1 and the second connecting block 2.

[0032] During installation, the V-shaped block acts as a guide, and the two connecting blocks can be quickly overlapped, improving the installation speed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
