When the locking assembly 4 is not locked, the first sliding member 46 can slide along the guide groove 442 or the receiving groove 211 to adjust and change a position of the load 3 in the Y direction. The first sliding member 46 includes a first clamping member 43 and a fixing member 45. The first clamping member 43 and the fixing member 45 can be fixedly connected to each other and inserted into the guide groove 442.
In some embodiments, the first clamping member 43 includes a mounting surface 431, a first clamping surface 432 opposite to the mounting surface 431, and a first protruding platform 433 extending vertically downward from the first clamping surface 432. The first protruding platform 433 includes a first fixing surface 4331 that is away from the first clamping surface 432. The first clamping surface 432 includes two rectangular grooves 4321.

The second clamping surface 471 is arranged toward the first guide rod 21 and opposite to the first clamping surface 432, and attaches to a surface of the first guide rod 21. The second abutting surface 472 is arranged toward the abutting member 48. A shape of the second abutting surface 472 is matched with an upper surface of the abutting member 48. In some embodiments, the second abutting surface 472 is a plane. The second abutting surface 472 abuts against the abutting member 48 when being mounted. The protruding wall 473 includes two sliding bars 4731 perpendicular to the protruding wall 473 and opposite to each other. The two sliding bars 4731 can slide in the sliding groove 2510. The second clamping surface 471 is also provided with a third through-hole 4710. In some embodiments, the third through-hole 4710 can be opened in a center of the second clamping surface 471, and the third through-hole 4710 can penetrate the second clamping member 47.
The abutting member 48 includes a third protruding platform 481 and a sliding block 482. In some embodiments, a cross section of the abutting member 48 has an inverted T-shape, and a width of the third protruding platform 481 is smaller than a width of the sliding block 482. In some embodiments, the third protruding platform 481 has a cuboid-like shape and it is not intended to limit the structure of the third protruding platform 481. The sliding block 482 can be arranged between the two extending walls 2512 of the mounting plate 25 and can slide along the sliding slot 2514. In some embodiments, a length and a width of the third protruding platform 481 are smaller than a length and a width of the third through-hole 4710, respectively. On the other hand, a length and a width of the sliding block 482 are greater than the length and the width of the third through-hole 4710, respectively. Therefore, the third protruding platform 481 can be inserted in the third through-hole 4710. A threaded hole 4810 is provided at the third protruding platform 481, and the threaded hole 4810 can be screwed to the screw portion 423. The threaded hole 4810 can match the first through-hole 4310 and the second through-hole 4510.
In some embodiments, during assembling, the intermediate member 44 can be embedded in the receiving groove 211. The first protruding platform 433 of the first clamping member 43 extends from a side of the guide groove 422 where the engaging wall 441 is arranged into the guide groove 422, and the second protruding platform 451 of the fixing member 45 extends from another side of the guide groove 442 into the guide groove 442. The first protruding platform 433 can fixedly connected to the second protruding platform 452. The first guide rod 21 can be sandwiched between the first clamping member 43 and the fixing member 45. The third protruding platform 481 of the abutting member 48 passes through the third through-hole 4710 of the second clamping member 47. The sliding bar 4731 of the second clamping member 47 slides in from an end of the mounting plate 25 along the sliding groove 2510. The threaded through-hole 251a of the mounting plate 25 is provided with the bolt to block the sliding block 482 and the sliding bar 4731. The connecting segment 422 of the driving member 42 sequentially passes through the first through-hole 4310 of the first clamping member 43, the second through-hole 4510 of the fixing member 45, and the third through-hole 4710 of the second clamping member 47. The screw portion 423 of the driving member 42 is screwed into the threaded hole 4810 of the abutting member 48.
Before the locking assembly 4 performs a locking action, the first sliding member 46 can slide along the guide groove 442, and the sliding block 482 of the abutting member 48 can slide along the sliding slot 2514 of the mounting plate 25 to adjust and change the position of the load 3.
When the locking assembly 4 is locked, the knob 41 can be rotated, such that the screw portion 423 of the driving member 42 and the threaded hole 4810 of the abutting member 48 can be further screwed. In this situation, the abutting member 48 can move toward the first guide rod 21, such that the sliding block 482 of the abutting member 48 can tightly abut against an upper wall of the sliding slot 2514 of the mounting plate 25 to tighten and lock the mounting plate 25. When the abutting member 48 moves toward the first guide rod 21, the mounting plate 25 is tightened. The extending wall 2513 of the mounting plate 25 can abut against the second abutting surface 472 of the second clamping member 47 to allow the first clamping member 43 and the second clamping member 47 to clamp the first guide rod 21 together, thereby locking the first sliding member 46. Two structures can be locked at the same time by simply operating one structure, which greatly improves the disassembling efficiency of the load bracket 2 and avoids the missing operation.
In some embodiments, as shown in
According to the disclosure, the load bracket 2 can utilize a driving connection between the driving member 42 of the locking assembly 4 and the abutting member 48, and clamping of the first guiding rod 21 by the first sliding member 46 and the second sliding member 49, and an abutting connection between the abutting member 48 and the mounting plate 25, and hence the first guide rod 21 and the mounting plate 25 of the load bracket 2 can be locked at the same time by simply operating the driving member 42. Therefore, a plurality of structures can be locked at the same time by simply operating one structure, which improves the disassembling/assembling efficiency of the load bracket 2 and avoids missing operation.
It is intended that the specification and examples be considered as exemplary only and not to limit the scope of the disclosure. Those skilled in the art will be appreciated that any modification or equivalents to the disclosed embodiments without departing from the spirit and scope of the present disclosure are intended to be encompassed within the scope of the present disclosure.
