Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a wall placement rack with adjustable use area, including: a rectangular frame 1, a hollow support plate a 2, a hollow support plate b 3, and a hollow support plate c 4;
[0027] One side of the rectangular frame 1 is abutted against a hollow pallet a2. One side of the rectangular frame 1 away from the lower part of the hollow pallet a2 is abutted against a hollow pallet b3. One side of the rectangular frame 1 away from the lower part of the hollow pallet b3 is abutted against a hollow pallet c4. An expansion mechanism 5 is arranged inside the hollow pallet a2, the hollow pallet b3 and the hollow pallet c4. A positioning mechanism 6 is arranged on the inner wall of the rectangular frame 1. L-shaped connecting pieces 7 are connected to the bottoms of both the hollow pallet a2 and the hollow pallet c4; The expansion mechanism 5 includes: an inner pallet 501, a limiting groove 502, a limiting rod 503, an inner rod retainer 504, an outer cylinder retainer 505 and a fastening bolt 506. Two groups of inner pallets 501 are slidably connected inside the hollow pallet a2, the hollow pallet b3 and the hollow pallet c4. The inner pallets 501 inside the hollow pallet a2 and the hollow pallet c4 are connected to the inner wall of the rectangular frame 1. The inner pallet 501 inside the hollow pallet b3 abuts against the inner wall of the rectangular frame 1. Limiting grooves 502 are formed in the front and rear parts of the inner pallet 501. Limiting rods 503 are slidably connected in the limiting grooves 502. The limiting rods 503 are connected to the inner walls of the hollow pallet a2, the hollow pallet b3 and the hollow pallet c4. An inner rod retainer 504 is connected to the upper surface of the inner pallet 501. An outer cylinder retainer 505 is slidably connected to the outside of the inner rod retainer 504. The outer cylinder retainer 505 is connected to the upper surface of another group of inner pallets 501. The bottom of the inner pallet 501 inside the hollow pallet b3 abuts against a fastening bolt 506. The fastening bolt 506 is threadedly connected to the lower part of the inner wall of the hollow pallet b3.
[0028] During specific implementation, loosen the fastening bolt 506 to move it away from the bottom of the inner pallet 501, pull the rectangular frames 1 on both sides to drive the inner pallets 501 to move towards both sides. The limiting rods 503 slide in the limiting grooves 502 to expand the areas of the hollow pallet a2, the hollow pallet b3 and the hollow pallet c4. At the same time, the inner rod retainer 504 slides in the outer cylinder retainer 505 to enclose the expanded hollow pallet a2, the hollow pallet b3 and the hollow pallet c4. Then tighten the fastening bolt 506 to squeeze the inner pallet 501 and fix the position of the inner pallet 501, so as to adjust the usable area of the wall placement rack.
[0029] Refer to Figures 2-4It can be known that the positioning mechanism 6 includes: a card slot 601, a through cavity 602, an insertion plate 603, a spring 604, a retaining frame 605, a reel 606, a rotating handle 607 and a pulling rope 608. Card slots 601 are provided at both the front and rear inner walls of the rectangular frame 1. A through cavity 602 is provided inside the inner support plate 501 within the hollow support plate b3. An insertion plate 603 is slidably connected within the through cavity 602. The insertion plate 603 is engaged within the card slot 601. The rear of the insertion plate 603 is connected to a spring 604. The rear of the spring 604 is connected to a retaining frame 605. The retaining frame 605 is connected to the inner upper part of the through cavity 602. A reel 606 is rotatably connected to the inner wall of the through cavity 602 away from the retaining frame 605. The bottom of the reel 606 is connected to a rotating handle 607. The rotating handle 607 passes through and rotates below the inner wall of the through cavity 602. A pulling rope 608 is connected to the outer side of the reel 606. The pulling rope 608 passes through the retaining frame 605 and the spring 604 and is connected to the rear of the insertion plate 603.
[0030] During specific implementation, rotating the rotating handle 607 drives the reel 606 to rotate, winds up the pulling rope 608. The pulling rope 608 pulls the insertion plate 603 out of the current card slot 601 and retracts it into the through cavity 602, compressing the spring 604. Then it is pushed to drive the hollow support plate b3 to drive the inner support plate 501 to slide along the inner wall of the rectangular frame 1, adjusting the distance between the hollow support plate b3 and the hollow support plates a2 and c4. Then release the rotating handle 607. The spring 604 pushes the insertion plate 603 to insert into the nearby card slot 601, fixing the current position of the hollow support plate b3, and using the pulling rope 608 to pull the reel 606 and the rotating handle 607 to rotate and reset, so as to improve the space utilization rate of this wall-mounted rack.
[0031] To sum up: When using this wall-mounted rack with adjustable usage area, first, drill holes on the wall and fix the L-shaped connecting piece 7 to the wall with expansion bolts to install this wall-mounted rack on the wall. Place the objects to be placed on the hollow support plates a2, b3 and c4 respectively, and use the inner rod retaining frame 504 and the outer cylinder retaining frame 505 to block them to prevent the placed items from slipping. If there are more items to be placed, loosen the fastening bolt 506, then pull the rectangular frames 1 on both sides, pull out the inner support plates 501 inside the hollow support plates a2, b3 and c4 to both sides, and then tighten the fastening bolt 506 again, and place the extra items on the inner support plates 501. If the height difference of the items to be placed is relatively large and cannot be placed on the hollow support plate a2, rotate the rotating handle 607 and push it to the hollow support plate b3, adjust the distance between the hollow support plate b3 and the hollow support plates a2 and c4, then release the rotating handle 607, and then place the items to be placed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
