In this embodiment, the unlocking assembly further includes a top plate 617 and a supporting plate 619, the top plate 617 is installed in the sliding groove 607, the supporting plate 619 is installed inside the pillar 601, and a plurality of compression springs are installed between the top plate 617 and the supporting plate 619. The lower connecting plate 612 is connected with the upper top plate 617 of the compression spring through the inner connecting rod 605. Hanging flower basket 3 upper end is provided with a plurality of lugs 4, and hanging flower basket door 7 is the rectangle framework of being constituteed for two front and back stand 601 that extend along vertical direction and two upper and lower crossbeams that extend along the front and back direction, has all seted up rectangle through-hole 622 on two front and back stand 601's the left surface for flexible subassembly can insert rectangle through-hole 622 about the rightmost end. The height of the hanging basket door 7 is consistent with that of the guardrail telescopic device. The hanging basket 3 and the hanging basket door 7 are both provided with cross railings.
The working process is as follows: starting a motor 2, the motor 2 drives a roller 11 to rotate clockwise, the roller rotates to enable a chain plate component meshed with the roller 11 to horizontally expand rightward, so that a guardrail expansion device is driven to move rightward, a folding rod 606 hinged with a hanging basket door 7 can drive a sliding block 621 on a rightmost guardrail expansion part 6 to move downwards to be close to the bottom of a sliding groove 607, a pressing block 620 on the guardrail expansion part 6 presses a pressure spring upper top plate 617 to move downwards, the pressure spring upper top plate 617 drives an inner connecting rod 605 to move downwards, the inner connecting rod 605 drives a lower connecting plate 612 to move downwards, an upper convex block 603 of the lower connecting plate 612 is staggered with a lower convex block 611 of the adjacent left guardrail expansion part 6 horizontally, and unlocking is completed. The basket door will bring the rightmost upright 601 to the right by means of the corresponding folding bar 606.
When the rightmost upright post starts to move, the folding rod of the guardrail telescopic part 6 on the left side starts to move. The right end of the lock cylinder opening 6101 of the lock hook 610 of the left guardrail expansion part 6 and the left end of the sleeve lock block 901 corresponding to the lock cylinder opening are positioned on the same vertical surface, because the lock hook 610 is fixedly connected with the right end of the folding rod 606 at a certain angle, the lock hook 610 can be clamped into the sleeve lock block 901 in the process of stretching the folding rod to the right, and the folding rod continues to rotate, the locking is completed, and the chain plate component can directly pull the folding rod of the guardrail expansion part corresponding to the folding rod. The locking of the locking hook 610 is timed such that locking of the locking hook 610 is simultaneous with unlocking of the next guardrail extension 6. Therefore, when the guardrail retractor device is expanded, one guardrail retractor part 6 and one guardrail retractor part 6 are gradually expanded from right to left.
When the guardrail telescoping device retracts, the roller 11 rotates anticlockwise, the folding rod 606 can rotate, in the adjacent guardrail telescoping portion, the upper convex block 603 on the upper end face of the left end of the lower connecting plate 612 on the right side can push against the lower convex block 611 on the lower end face of the right end of the lower connecting plate 612 on the left side, and finally the left convex block 611 on the lower end face of the right end of the lower connecting plate 612 on the left side is located for clamping, so that the retraction locking is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
