[0019] The present invention provides a light steel structure building keel connector and an installation method thereof. It has the following beneficial effects:

[0020] (1) The present invention, through the setting of the installation device, can realize the rapid positioning and installation of the secondary keel by aligning the secondary keel with the docking plate and then pressing down the secondary keel in cooperation with the slider, the drive block and the No. 2 spring. When the secondary keel needs to be disassembled, the secondary keel can be disassembled by manually pressing up the pressing plate in cooperation with the transmission block and the No. 1 spring, thereby improving the efficiency of installation and being able to be flexibly adjusted according to actual needs to adapt to different building structures and design requirements.

[0021] (2) The present invention, through the setting of the positioning device, can install the sliding plate on the right side of the secondary keel, and the downward force of the secondary keel drives the extrusion column to descend, and the cylinder and the telescopic pipe drive the push block to rise. The push block rises and cooperates with the slide rod to make the installation plate break away from the limit of the slide rod. At this time, the bolt is inserted into the slot hole of the installation plate, and the bolt is inserted into the slot hole of the secondary keel by manually pushing the installation plate, thereby realizing the positioning and installation of the bolt.

[0022] (3) The present invention, through the arrangement of the positioning device and the anti-reversal device, when the mounting plate drives the bolt to be inserted into the slot hole of the secondary keel, the clamping plate is manually rotated toward the mounting plate until it contacts the mounting plate, and the clamping plate is limited by manually rotating the button block, and the installation is completed by rotating the bolt to prevent the mounting plate from sliding during the installation process. The cooperation of the round shaft and the limit block makes it impossible for the bolt to reverse, which can ensure that the bolt maintains the correct tightening force, thereby improving the stability of the installation.

[0023] (4) The present invention, through the setting of the lifting device, drives the gear to rotate by manually rotating the turntable, and the gear rotates in coordination with the rack to drive the sliding plate to rise, thereby realizing installation at different heights from the secondary keel, thereby improving the flexibility of installation. When the lifting is stopped, the card strip is manually pushed until it contacts the baffle, and the card strip will then lock the triangular card block, which makes the gear unable to rotate, thereby limiting the gear and preventing the gear from being accidentally touched by external force, thereby avoiding height deviation during installation.

[0044] The positioning device also includes a round rod 502, a mounting plate 503, a support rod 504, a button block 505, a clamping plate 506 and a rack 507. The round rod 502 is fixedly installed on the right side of the sliding plate 501, the mounting plate 503 slides through the round rod 502, the support rod 504 is fixedly installed on the right side of the sliding plate 501, the button block 505 is rotatably installed on the right side of the support rod 504, the clamping plate 506 is rotatably installed on the right side of the sliding plate 501, and the rack 507 is fixedly installed on the front side of the sliding plate 501.

[0045] The anti-reversal device includes a circular shaft 508 and a limit block 509. The circular shaft 508 is fixedly installed in the groove of the sliding plate 501. The limit block 509 slides through the circular shaft 508. A No. 5 spring is arranged between the limit block 509 and the circular shaft 508. The limit block 509 is reset by the arranged No. 5 spring.

[0046] The lifting device includes a gear 601, a triangular block 602, a turntable 603, a baffle 604 and a clamping strip 605. The gear 601 is rotatably installed on the right side of the secondary keel 2, the triangular block 602 is fixedly installed on the inner wall of the gear 601, the turntable 603 is fixedly installed on the right side of the gear 601, the baffle 604 is fixedly installed on the right side of the turntable 603, and the clamping strip 605 is slidably installed and passes through the turntable 603.

[0048] When this embodiment is working: by installing the sliding plate 501 on the right side of the secondary keel 2, the downward force of the secondary keel 2 drives the extrusion column 401 to descend, and the descent of the extrusion column 401 will squeeze the gas in the cylinder 402, so that the gas in the cylinder 402 drives the push block 405 to rise through the telescopic pipe 403, and the push block 405 rises and contacts the inclined surface of the slide bar 407, so that the slide bar 407 moves backward, and the slide bar 407 moves backward to release the restriction on the mounting plate 503. At this time, the bolt is inserted into the slot hole of the mounting plate 503, and the mounting plate 503 is manually pushed to insert the bolt into the slot hole of the secondary keel 2. At this time, the clamping plate 506 is manually rotated toward the mounting plate 503 until it contacts the mounting plate 503, and then the clamping plate 506 is limited by manually rotating the button block 505, and then the installation can be completed by rotating the bolt to prevent the installation from being blocked. During the process, the mounting plate 503 slides. By setting the limiting block 509, the bolt is rotated to contact the inclined surface of the limiting block 509, so that the limiting block 509 slides to the outside of the circular shaft 508. At this time, the bolt can rotate continuously. When the bolt is reversed, the non-inclined surface of the limiting block 509 is used to limit the bolt to prevent it from loosening. The turntable 603 is manually rotated to drive the gear 601 to rotate. The rotation of the gear 601 drives the rack 507 to rise. The rising of the rack 507 drives the sliding plate 501 to rise, so as to achieve installation at different heights from the secondary keel 2. When the lifting stops, the card strip 605 is manually pushed to contact the baffle 604. At this time, the card strip 605 will jam the triangular card block 602. The jamming of the triangular card block 602 makes the gear 601 unable to rotate, thereby limiting the gear 601.
