[0002] A keel is a lightweight steel alloy material used to support and secure the interior structure of a building. Depending on where it's used within the building, it can be categorized as ceiling keels, vertical wall keels, floor keels, and suspended keels. Ceiling keels are generally used to support and install building ceilings, effectively supporting the roof structure. Currently, traditional ceiling keels consist of secondary keels and cross-bracing keels suspended from hangers and main keels. Depending on the structure of the building's ceiling, the secondary keels are connected to the cross-bracing keels and secondary keels, as well as to the extensions between the two sets of secondary keels, using connecting plates with through holes and rivets. The installation requires using external tools such as electric screwdrivers to tighten multiple sets of rivets and install the connecting plates between two sets of secondary keels or between a cross-bracing keel and a secondary keel. The traditional connecting plate assembly method for secondary keels is complex and cumbersome, not only damaging the surface structure of the secondary keels and cross-bracing keels, but also making maintenance and disassembly between the ends of the cross-bracing keels and secondary keels extremely inconvenient.

[0026] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1-8As shown, the utility model provides a new type of keel, including a main keel 1; a hanger 2 is nested on the outer side of the main keel 1; it also includes a secondary keel 3 and a cross-bracing keel 4; the secondary keel 3 includes an exoskeleton 301, a lock tongue 302, a guide rod 303, a pull handle 304, a top pressure block 305, a return spring 306, a vertical plate 307, a guide support rod 308, a limit baffle 309 and a top pressure spring 310; the inner side of the exoskeleton 301 is welded to the limit baffle 309, a through hole is provided at the center of the limit baffle 309, the front end of the limit baffle 309 is welded to the top pressure spring 310, the front end of the top pressure spring 310 is welded to the top pressure block 305, the rear end of the top pressure block 305 is welded to the guide support rod 308, and the guide support rod 308 is inserted in the limit baffle The left and right sides of the top pressure block 305 are welded with a pull handle 304 in the through hole of the plate 309; the upper and lower sides of the vertical plate 307 are welded with the exoskeleton 301, the left and right ends of the vertical plate 307 are welded with a guide rod 303, and the outer side of the guide rod 303 is slidably connected to the lock tongue 302; one end of the return spring 306 is welded with the lock tongue 302, and the other end of the return spring 306 is welded with the vertical plate 307; the cross-bracing keel 4 includes a cross-frame shell 401, a lock hook 402, a two-way threaded rod 403 and a locking knob 404; the interior of the cross-frame shell 401 is rotatably connected to the two-way threaded rod 403, the outer side of the two-way threaded rod 403 is welded with the locking knob 404, and the upper side of the cross-frame shell 401 is slidably connected to the lock hook 402.

[0028] In the embodiment of the present disclosure, the upper side and the lower side of the cross frame shell 401 are provided with a through groove running through from top to bottom, and the left side and the right side of the cross frame shell 401 are bonded with rubber gaskets. The rubber gaskets increase the contact friction between the left end and the right end of the cross frame shell 401 and the left side and the right side of the cross frame shell 401, thereby preventing the cross frame shell 401 from being offset along the surface of the outer frame 301 due to vibration, and improving the structural stability of the assembly of the cross frame shell 401 and the outer frame 301.

[0029] In the embodiment of the present disclosure, the upper and lower sides of the exoskeleton 301 are provided with grooves that pass through from front to back, and the rear side of the exoskeleton 301 is provided with two groups of convex plates, each group of convex plates is provided with square through grooves that are symmetrically distributed on the left and right sides, and the left and right sides of the exoskeleton 301 are provided with long through grooves that are symmetrical on the left and right sides, and a pull handle 304 is inserted inside the long through groove. The pull handle 304 outside the through groove of the exoskeleton 301 drives the internal pressure block 305 of the exoskeleton 301 to move backward, and the pressure block 305 disengages from the lock tongue 302. The lock tongue 302 moves left and right centripetally along the guide rod 303 under the traction of the return spring 306, and the lock tongue 302 disengages from the convex plate through groove of the other group of exoskeleton 301, completing the unlocking of the lock tongue 302.

[0030] In the embodiment of the present disclosure, there are two groups of lock tongues 302, and the lock tongues 302 are symmetrically distributed on the left and right. Each group of lock tongues 302 has a T-shaped structure. The T-shaped structure of the lock tongue 302 is inserted into the square groove of the convex plate of another group of external skeletons 301. The lock tongue 302 limits and locks the external skeleton 301. The lock tongue 302 is provided with a through hole that passes through the left and right. The guide rod 303 is inserted into the through hole of the lock tongue 302. The lock tongue 302 moves left and right along the guide rod 303, so that the lock tongue 302 can stably extend and retract and insert in the square groove of the convex plate of the other group of external skeletons 301.

[0031] In the embodiment of the present disclosure, the front side surface of the top pressure block 305 is a semi-circular arc surface structure, and the rear end of the lock tongue 302 is fitted into the arc surface structure of the top pressure block 305. In the process of the top pressure block 305 moving forward under the elastic force of the top pressure spring 310, the semi-circular arc surface structure is used to push the two groups of lock tongues 302 to move left and right apart, so that the lock tongues 302 automatically penetrate into the convex plate groove of the outer frame 301 to perform locking work.

[0032] In the embodiment of the present disclosure, there are two groups of locking hooks 402, which are symmetrically distributed on the left and right. The locking hooks 402 have a J-shaped structure. The lower side of each group of locking hooks 402 is provided with a convex plate, which is embedded in the through grooves on the upper and lower sides of the cross frame shell 401. The center of the convex plate of the locking hook 402 is provided with a threaded through hole that passes through the left and right. The positive threaded end of the outer side of the two-way threaded rod 403 is engaged and connected in the threaded through hole of the convex plate of the right locking hook 402, and the reverse threaded end of the outer side of the two-way threaded rod 403 is engaged and connected in the threaded through hole of the convex plate of the left locking hook 402. During the rotation of the two-way threaded rod 403, the two groups of locking hooks 402 are driven to move left and right. The J-shaped structure of the locking hook 402 is embedded in the groove on the upper side of the two groups of exoskeletons 301. The locking hook 402 cooperates with the end of the cross frame shell 401 to clamp the exoskeleton 301, completing the horizontal pulling and locking installation of the two groups of exoskeletons 301 by the locking hook 402.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When the utility model is performing the extension and assembly installation of the secondary keel 3 and the secondary keel 3, the front end of one set of secondary keels 3 is docked and deeply inserted between the two sets of convex plates at the rear end of the outer frame 301 of the other secondary keel 3. At this time, the pull handle 304 is manually pulled backward, and the pull handle 304 drives the top pressure block 305 to overcome the elastic force of the top pressure spring 310 and move backward. The top pressure block 305 is separated from the two sets of lock tongues 302. The two sets of lock tongues 302 move toward the vertical plate 307 along the guide rod 303 under the elastic pulling force of the two sets of return springs 306, and the lock tongues 302 retract to the outer frame. 301, the front end of the secondary keel 3 continues to penetrate between the two sets of convex plates at the rear end of the outer frame 301 of the other secondary keel 3, until the lock tongue 302 is opposite to the through groove of the convex plate at the rear end of the outer frame 301 of the other set of secondary keels 3, and then the pull handle 304 is released, and the pressing block 305 moves forward under the elastic force of the pressing spring 310. The semicircular arc surface structure on the front side of the pressing block 305 pushes the rear ends of the two sets of lock tongues 302, so that the two sets of lock tongues 302 overcome the elastic pulling force of the return spring 306 and move left and right along the guide rod 303, allowing the two sets of lock tongues 302 to separate and move left and right. 02 is inserted into the through grooves of the two groups of convex plates at the rear end of the outer frame 301 of another group of secondary keels 3, completing the plug-in lock connection of one group of secondary keels 3 to the other group of secondary keels 3 through the lock tongue 302. If it needs to be removed, manually pull the pull handle 304 backward, and the pull handle 304 drives the top pressure block 305 to disengage from the two groups of lock tongues 302 backward. The lock tongue 302 disengages from the two groups of convex plate through grooves at the rear end of the outer frame 301 under the elastic tension of the return spring 306, and then the two groups of secondary keels 3 can be separated front and back. During operation, the locking hook 402 is placed in the groove of the exoskeleton 301, and then the locking knob 404 is manually turned. The locking knob 404 drives the bidirectional threaded rod 403 to rotate. Since the convex plate threaded through hole on the lower side of the locking hook 402 engages with the positive threaded end and the reverse threaded end of the outer side of the bidirectional threaded rod 403, the bidirectional threaded rod 403 drives the two sets of locking hooks 402 to move toward the center of the cross frame shell 401. At this time, the locking hook 402 and the cross frame shell 401 clamp the groove wall of the exoskeleton 301, completing the clamping and locking connection between the cross-bracing keel 4 and the secondary keel 3.

[0035] All of the above components are installed, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies and may be implemented as long as they achieve the desired effect. The main keel 1 and hangers 2 used are commonly available on the market and require only connection according to the included instruction manual, so further description is omitted here.
