DETAILED DESCRIPTION
[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.
[0024] Example: A metal shelf locking device, such as Figure 1-Figure 5As shown, it includes a base 1, a support frame 2, a connecting plate 4, a placement plate 5 and a slider 501. The multiple support frames 2 are distributed in a U-shape and are connected to the four corners of the top of the base 1 by welding. Multiple mounting holes 3 are distributed vertically and are spaced apart on the support frame 2. Every three connecting plates 4 are connected between every two laterally aligned support frames 2. Multiple sliders 501 are slidably connected to the inside of the connecting plate 4. The placement plate 5 is connected between every four sliders 501 by welding. Strip grooves are provided on both sides of it to increase the fulcrum and facilitate stable holding. A locking assembly is also included, which is arranged between the support frame 2 and the connecting plate 4.
[0025] like Figure 2 and Figure 5 As shown, the locking assembly includes a fixing plate 13, a second spring 14, a card rod 15, a limit block 16, a protruding rod 1601, a third spring 17, an extrusion block 18 and a knob 19. A plurality of fixing plates 13 are distributed left and right, and are respectively connected to the left and right sides of the top of the connecting plate 4 by welding. The card rod 15 is slidably connected between two adjacent fixing plates 13 and is engaged with the corresponding mounting hole 3, so that the connecting plate 4 is fixed to the support frame 2. The second spring 14 is sleeved on the outside of the card rod 15, and its two ends are fixedly connected to the corresponding fixing plate 13 and the card rod 15 respectively. The two limit blocks 16 are distributed up and down and are slidably connected to the inside of the card rod 15. The limit block 16 is provided with a straight surface and an inclined surface, wherein the inclined surface faces outward and the straight surface faces inward with the support frame 2 Contact, so that the card rod 15 is limited on the support frame 2, the third spring 17 is connected between the limit block 16 and the card rod 15 by welding, the protruding rod 1601 is connected to the limit block 16 by welding, and the knob 19 is rotatably connected to the end of the card rod 15 away from the baffle 6. Its outer ring is provided with multiple semicircular protrusions distributed circumferentially, which can increase the contact area of the knob 19 and facilitate rotation. The outermost circle diameter of the knob 19 is the same as the diameter of the card rod 15, ensuring that the knob 19 can pass through the support frame 2 together with the card rod 15. The two extrusion blocks 18 are symmetrically distributed and are connected to the side of the knob 19 close to the limit block 16 by welding. The end of the protruding rod 1601 that is not connected to the limit block 16 is located between the two extrusion blocks 18.
[0026] like Figure 2-Figure 4As shown, it also includes limited material plate 9, rubber pad 10, first spring 11 and guide rod 12, three limited material plate 9 are distributed at intervals, are respectively connected to three rear connecting plate 4, two recesses 901 are distributed on the left and right sides, are respectively set up in limited material plate 9 left and right sides and are located above the corresponding two sliding block 501, are staggered with each other, rubber pad 10 is connected to the left side of limited material plate 9 by welding, its height is consistent with the height of limited material plate 9, three guide rods 12 are distributed at intervals, are respectively connected to three rear connecting plate 4 by welding and are connected with the corresponding limited material plate 9, first spring 11 is sleeved on the outside of guide rod 12, and its two ends are respectively fixedly connected with the corresponding connecting plate 4 and limited material plate 9.
[0027] As shown in the figure, Figure 2 It also includes baffle 6, connecting shaft 7 and torsion spring 8, three connecting shafts 7 are vertically distributed, are respectively connected to three front connecting plate 4 by welding, baffle 6 is rotatably connected to the outside of connecting shaft 7, and a plurality of T-shaped grooves are arranged on the baffle 6, which can increase the friction between the baffle 6 and the goods, two torsion springs 8 are symmetrically distributed, are sleeved on the left and right ends of connecting shaft 7, and the two ends of torsion spring 8 are respectively fixedly connected with the corresponding connecting plate 4 and baffle 6.
[0028] Initially, the second spring 14 is in a stretched state. When the shelf needs to be used, the base 1 is placed in a suitable position indoors to ensure that the rear side of the base 1 and the two rear support frames 2 are close to the wall. When the height of the placement plate 5 needs to be adjusted, the user first rotates the knob 19 to drive the extrusion block 18 to rotate and squeeze the protruding rod 1601. The protruding rod 1601 drives the limit block 16 to slide into the inside of the card rod 15, and the third spring 17 is compressed. Then, the knob 19 is slowly released. During the release, the second spring 14 returns to its original state, causing the card rod 15 to move inward and disengage from the mounting hole 3. To unlock the connecting plate 4, the card rod 15 drives the limit block 16 and the knob 19 to move inward through the support frame 2. After passing through, the knob 19 is completely loosened, so that the extrusion block 18 no longer has the force to squeeze the protruding rod 1601, and the third spring 17 returns to its original state, causing the limit block 16 to pop out from the inside of the card rod 15, and then move the connecting plate 4 up and down to make the placement plate 5 at a suitable height. After the adjustment is completed, repeat the above steps to make the limit block 16 slide into the inside of the card rod 15 again, and then pull the card rod 15 outward to engage with the mounting hole 3. The second spring 14 is then stretched, and the card rod 1 5 at the same time drives the limit block 16 and the knob 19 to move outward and pass through the mounting hole 3. After the clamping, completely loosen the knob 19, and the third spring 17 returns to its original state, prompting the limit block 16 to pop out from the inside of the clamping rod 15 again, so that it directly contacts the support frame 2, and the connecting plate 4 is locked. When it is necessary to replace the placement plate 5, press the rubber pad 10 and pull the limiting plate 9 to the left to the appropriate position, so that the two grooves 901 are aligned with the corresponding two sliders 501 respectively, and the first spring 11 is compressed. After alignment, take out the placement plate 5 to be replaced, put in the new placement plate 5, and after placing it, loosen it. Open the rubber pad 10, and the first spring 11 will return to its original shape, prompting the limiting plate 9 to move to the right, so that the two grooves 901 are staggered with the corresponding two sliders 501, so that the limiting plate 9 limits the second placement plate 5 from the left to the right, so that the four placement plates 5 are close to each other to form a complete placement surface. When it is necessary to place goods, rotate the baffle 6 downward 90 degrees, and the torsion spring 8 will be deformed. Then, place the goods neatly on the placement plate 5. After placing them, release the baffle 6, and the torsion spring 8 will return to its original shape, prompting the baffle 6 to rotate upward 90 degrees to limit the goods on the placement plate 5.
