Abstract
Description
Technical Field
[0001] This utility model relates to the field of keel connector technology, and more specifically, to a W-shaped keel connector. Background Technology
[0002] Light steel keel is made of cold-formed light steel material, commonly galvanized steel sheet. It typically has a C-shaped or U-shaped cross-section and possesses high strength and stability. Light steel keel is widely used in interior decoration for partition walls, suspended ceilings, soundproof walls, lightweight wall structures, and other building structures. It provides a lightweight, sturdy, and reliable support system for installing gypsum board, sound insulation materials, and other decorative materials.
[0003] Currently, commonly used light steel keels are all simple zigzag or channel-shaped structures, with a small contact area between the light steel keel and the material, which reduces the stability of the connection.
[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a W-shaped keel connector, in order to achieve a more practical purpose. Utility Model Content

[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A W-shaped keel connector, the W-shaped keel connection structure includes a W-shaped connector and a W-shaped keel, the W-shaped connector includes an L-shaped connector and two grooved connectors, the L-shaped connector and the two grooved connectors are integrally formed W-shaped structures, and the two grooved connectors are respectively disposed at both ends of the L-shaped connector;
[0010] The grooved connector includes a base plate and two upright plates. The base plate and the two upright plates are combined into an integral structure. The upright plates are fishhook shaped and are located on both sides of the base plate and are symmetrical about the central axis. The upright plates are provided with slots and at least one tooth is provided on each upright plate.
[0011] The W-shaped keel has several locking holes, and the locking teeth engage with the corresponding locking holes.
[0012] Furthermore, the upright plate is provided with several connection holes one, the connection holes one are in the same plane, the W-shaped keel is provided with connection holes two, and after the W-shaped connector is engaged with the W-shaped keel, the center of the connection hole one coincides with the center of the corresponding connection hole two.

[0014] Furthermore, the teeth are arc-shaped.
[0015] Furthermore, the side of the upright plate is provided with a buckle, and the buckle is located close to the slot.
[0016] Furthermore, the locking teeth are disposed inside the locking slot.
[0017] 3. Beneficial effects
[0018] Compared with existing technologies, the advantages of this utility model are:
[0019] This solution uses a W-shaped keel connector instead of a traditional keel connector. This W-shaped keel connector has a W-shaped structure and is lightweight, which can maximize the contact area between the keel and the material. At the same time, with the connection hole on the W-shaped keel connector, a stable connection between the W-shaped connector and the W-shaped keel can be achieved by bolts, thereby enhancing the stability of the connection between the keel and the material.
