It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0021] The following describes a steel structure locking device for building construction provided by some embodiments of the present utility model in combination with the accompanying drawings.

[0022] Combined with Figures 1-5 As shown, a steel structure locking device for building construction provided by the present utility model includes: a tie rod 100, a fixed hook 200, and a lock head 400 and a sleeve lock assembly 300 respectively fixed on the surfaces of the tie rod 100 and the fixed hook 200. An inner side of the tie rod 100 is slidably sleeved with a telescopic rod 120. One end of the telescopic rod 120 is provided with a movable hook 110. A bottom surface of the telescopic rod 120 is fixedly installed with a locking block 121. A bottom surface of the movable hook 110 is provided with a plurality of locking grooves 130 adapted to the locking block 121. A surface of the lock head 400 is provided with lock ears 410 and a plurality of lock ears 410 are fixedly installed on the surface of the lock head 400. The sleeve lock assembly 300 includes a fixed sleeve 310, an inner lock shaft 320, and a counter sleeve 330. One end of the counter sleeve 330 is provided with a lock sleeve ring 331 slidably sleeved on a surface of the inner lock shaft 320. Two ends of the inner lock shaft 320 are respectively provided with a lock groove 321 and an upper locking block 322. An inner side of the fixed sleeve 310 is provided with a torsion spring 311 connected to the inner lock shaft 320.

[0023] In this embodiment, the number of the lock ears 410 is several and they are evenly distributed in a circumferential direction. An inner side of the inner lock shaft 320 is provided with a lock groove 321 adapted to the lock ears 410, and the distance between adjacent lock grooves 321 is equal to the arc length of the lock ears 410.

[0024] Specifically, the engagement effect between the lock ears 410 and the inner lock shaft 320 is achieved by the lock ears 410 escaping into the inner part of the inner lock shaft 320 and rotating.

[0025] In this embodiment, the counter sleeve 330 is slidably sleeved on an inner side of the fixed sleeve 310 and sleeved on an outer periphery of the inner lock shaft 320. The contact pin 420 is arranged relatively perpendicular to a surface of the counter sleeve 330.

[0026] In this embodiment, the outer periphery of the locking block 322 is a polygonal structure, and the interior of the locking ring 331 is provided with a sleeve hole that matches the surface of the locking block 322 .

[0027] Specifically, when the lock head 400 is engaged with the surface of the inner lock shaft 320 , the abutment pin 420 is used to push the abutment sleeve 330 and the lock sleeve ring 331 to move, so that the lock sleeve ring 331 is sleeved on the surface of the upper locking block 322 to achieve a locking effect.

[0028] In this embodiment, two sections of the torsion spring 311 are respectively fixed to the fixed sleeve 310 and the surface of the inner locking shaft 320 , and are used to drive the inner locking shaft 320 to axially deflect and elastically restore.

[0029] In this embodiment, a sleeve hole for the telescopic rod 120 is provided on the inner side of the pull rod 100, and the cross-sectional area of ​​the sleeve hole is the sum of the cross-sectional areas of the telescopic rod 120 and the locking block 121. The locking block 121 is arranged perpendicular to the surface of the telescopic rod 120 and the surface direction of the telescopic rod 120.

[0030] Specifically, when the movable hook 110 is free from external force, the locking block 121 and the locking groove 130 can freely adjust the telescopic length of the telescopic rod 120 , and the length of the movable hook 110 can be locked when the movable hook 110 is clamped and locked.

[0031] The working principle and use process of this utility model:

[0032] When the locking device is in use, the length of the pull rod 100 and the movable hook 110 is adjusted by engaging the locking block 121 with the locking groove 130, so that the fixed hook 200 and the movable hook 110 are clamped and contacted with the two sides of the docking template, and the inner lock shaft 320 is manually rotated to make it elastically deflect and move. After it is sleeved and engaged with the lock head 400, the inner lock shaft 320 is released to allow the torsion spring 311 to twist and drive the inner lock shaft 320, so that the lock groove 321 and the lock ear 410 are transfer-engaged and the synchronous abutment pin 420 pushes the abutment 330 to make the lock ring 331 sleeved on the surface of the upper locking block 322, avoiding the upper locking block 322 from rotating again, and stably locking the two; during unlocking, after the pull rod 100 and the fixed hook 200 are unhooked, the relative deflection of the lock head 400 and the inner lock shaft 320 can be unlocked by relatively rotating the pull rod 100 and the fixed hook 200.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
