Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a movable shelving unit with adjustable spacing. Background Technology

[0002] Storage racks are generally made up of a base plate and support columns to hold miscellaneous items. They are mostly supported by strip-shaped brackets and supported by a base plate. They have a unique shape, ingenious design, are easy to assemble and disassemble, and the open design makes the stored items visible at a glance.

[0003] However, most shelving units are either designed as a single piece, making it difficult to adjust the distance between the base plates on which items are placed, or they require self-assembly. However, most self-assembly units require screws and matching tools, and the screws are easy to roll off or be lost during assembly, which is quite inconvenient for users who want to assemble the shelving unit.

[0004] In order to facilitate the assembly of the storage rack and to allow for adjustment of the spacing between the base plates on which objects are placed, this application proposes a movable storage rack with adjustable spacing. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-4An adjustable-spacing mobile shelf includes a crossbar 5, with base bars 1 on both the left and right sides of the crossbar 5. Universal wheels 6 are installed on the front and rear sides of the bottom end of each base bar 1. A groove 12 is formed on the front side of the top of each base bar 1. Locking blocks 20 are fixedly connected to both ends of the crossbar 5. The outer wall shape of each locking block 20 matches the inner wall shape of the groove 12. A positioning groove 21 is formed on the upper rear side of each locking block 20. A slider 16 is slidably connected to the upper rear side of the inner wall of the groove 12. The front end shape of each slider 16 matches the inner wall shape of the positioning groove 21. A rack 15 is fixedly connected to the rear end of each slider 16. A sliding groove frame 13 is slidably connected to the top of each rack 15. The top of each sliding groove frame 13 is fixedly connected to the inner wall of the groove 12 at the top of the base bar 1. A spring 14 is fixedly connected to the rear end of each rack 15. The rear end of each spring 14 is fixedly connected to the inner wall of the base bar 1. Each end has a retaining groove 10. The top of the bottom rod 1 is provided with an adjusting rod 2 located above the retaining groove 10. The inner wall of the adjusting rod 2 is provided with several slots 3. The upper and lower sides of the front end of the adjusting rod 2 are provided with a shelf 4. The inner wall of the shelf 4 is provided with an anti-slip pad. The inner wall of the bottom rod 1 is provided with a gear 17 located below the rack 15. The top of the gear 17 is meshed with the bottom end of the rack 15. The opposite end of the gear 17 is fixedly connected to a rotating shaft 18. The middle of the outer wall of the rotating shaft 18 is rotatably connected to the inner wall of the opposite end of the bottom rod 1. The opposite end of the rotating shaft 18 is fixedly connected with a knob 8. The opposite end of the gear 17 is fixedly connected to an extension shaft 19. The middle of the outer wall of the extension shaft 19 is rotatably connected to the inner wall of the opposite end of the bottom rod 1. The opposite side of the extension shaft 19 is provided with a traction rod 11. The shape of the left and right ends of the traction rod 11 matches the shape of the inner wall of the opposite end of the extension shaft 19.

[0030] To further explain, first place the two base rods 1 on the left and right sides, which are the basic support parts of the entire shelf. Next, align the two ends of the traction rod 11 with the opposite ends of the extension shafts 19 on both sides and insert them. This step connects the two base rods 1. Then, align the locking blocks 20 at both ends of the crossbar 5 with the grooves 12 and insert them. At this time, turn the knob 8 on either side, so that the knob 8 drives the rotating shaft 18, and the gear 17 on the corresponding side rotates. Due to the connection of the traction rod 11, the extension shaft 19 on the other side will also drive the corresponding gear 17 to rotate synchronously. Under the meshing action of the gear 17 and the rack 15, the rack 15 slides backward in the slide frame 13, while squeezing the spring 14. The rack 15 drives the slider 16 to slide into the base rod 1. When the locking block 20 is fully inserted into the groove 12, release the knob 8. Under the elastic action of the spring 14, the rack 15 returns to its original position, and the slider 16 extends outward and inserts into the positioning groove 21. This completes the installation of the crossbar 5 and realizes the connection between the two base rods 1.

[0031] Example 2

[0032] Please see Figures 5-9Further, based on Embodiment 1, each adjusting rod 2 has a fixed connecting plate 23 at its bottom end. The shape of the outer wall of the connecting plate 23 matches the shape of the inner wall of the fixing groove 10. A shaped groove 24 is opened on the lower side of the inner wall of the connecting plate 23. A hollow cylinder 22 is fixedly connected to the rear end of the right adjusting rod 2 at the lower part of the slot 3. Push bolts 29 are slidably connected to the inner walls of both ends of the hollow cylinder 22. A disc 28 is fixedly connected to the outer wall of the push bolt 29 at the inner side of the hollow cylinder 22. A sliding bolt 9 is slidably connected to the inner wall of the bottom rod 1 at both the left and right sides of the fixing groove 10. A pressure plate 7 is fixedly connected to the opposite end of the sliding bolt 9. The outer wall of the pressure plate 7 is slidably connected to the inner wall of the bottom rod 1. A spring 25 is fixedly connected to the opposite end of the pressure plate 7 at the outer wall of the sliding bolt 9. Connected to the inner wall of the base rod 1, the shape of the opposite end of the sliding bolt 9 matches the shape of the upper side of the inner wall of the irregular groove 24. The front and rear ends of the sliding bolt 9 are provided with grooves 26 on opposite sides. The distance between the opposite ends of the inner walls of the front and rear grooves 26 is the same as the width of the lower side of the inner wall of the irregular groove 24. The left and right sides of the rear end of the shelf 4 are fixedly connected with the insert block 31. The shape of the rear end of the insert block 31 matches the shape of the inner wall of the slot 3. The rear left end of the right insert block 31 is provided with a grid groove 32. The left end of the push bolt 29 is fixedly connected with the fitting block 27. The shape of the upper side of the outer wall of the fitting block 27 matches the shape of the inner wall of the grid groove 32. The left end of the disc 28 is located outside the push bolt 29 and is fixedly connected with the spring 30. The left end of the spring 30 is fixedly connected to the inner wall of the hollow cylinder 22.

[0033] To further explain, when the pressure plate 7 is pressed, the pressure plate 7 pushes the sliding bolt 9 outward to the bottom rod 1. During this process, the spring 25 is compressed. When the sliding bolt 9 slides outward, the grooves 26 on both sides of its outer wall will be in the position of the retaining groove 10. Then, the guide plate 23 at the bottom of the adjusting rod 2 is aligned with the retaining groove 10 and inserted. When the lower side of the inner wall of the irregular groove 24 passes the grooves 26 on both sides, it will slide down against the inner wall of the grooves 26 on both sides until the guide plate 23 is fully inserted into the retaining groove 10. Then, the pressure plate 7 is released. Relying on the elastic potential energy of the spring 25, the sliding bolt 9 returns to its original position. The complete part of the outer wall of the sliding bolt 9 will slide into the upper side of the inner wall of the irregular groove 24, thereby forming a limiting effect on the guide plate 23. The assembly between the bottom rod 1 and the adjusting rod 2 is then completed.

[0034] Insert the insert 31 on the back of the shelf 4 into the slot 3 of the corresponding height, and press the push bolt 29 at the same time. The push bolt 29 slides inside the hollow cylinder 22, causing the disc 28 to squeeze the spring 30, so that the fitting block 27 moves away from one end of the hollow cylinder 22. After the insert 31 is fully inserted into the slot 3, release the push bolt 29. Under the elastic action of the spring 30, the fitting block 27 returns to its original position and is locked in the grid groove 32, thus limiting the insertion block 31 on the right side. This completes the assembly of one shelf 4. Repeat this step to complete the assembly of the other shelf 4. If it is necessary to adjust the distance between the two shelves 4, simply press the push bolt 29 to move the fitting block 27 away from the grid groove 32, release the limitation on the insertion block 31 on the right side, pull the shelf 4 away from the front end of the adjusting rod 2, select the slot 3 of the appropriate height, and reinstall it according to the above steps. This achieves the adjustable distance between the shelves 4.

[0035] Working principle: First, place the two base rods 1 to the left and right sides, then align the two ends of the traction rod 11 with the opposite ends of the two extension shafts 19 and insert them. Next, align the locking blocks 20 at both ends of the crossbar 5 with the grooves 12 and insert them. At the same time, rotate the knob 8 on either side, so that the rotating shaft 18 drives the corresponding gear 17 to rotate. Through the connecting action of the traction rod 11, the other extension shaft 19 drives the corresponding gear 17 to rotate, thus achieving synchronous rotation of the gears 17 on both sides. Then, under the meshing relationship between the gear 17 and the rack 15, the rack 15 slides backward on the slide frame 13 and squeezes the spring 14. At the same time, the rack 15 drives the slider 16 to slide into the base rod 1. Then, after the locking blocks 20 are fully inserted into the grooves 12, release the knob 8. Then, under the elastic action of the spring 14, the rack 15 is reset, so that the slider 16 extends outward and is inserted into the positioning groove 21. This realizes the installation of the crossbar 5 and the assembly between the two base rods 1.

[0036] Next, the adjusting rod 2 is assembled. By pressing the pressure plate 7, the sliding bolt 9 is pushed outward to the bottom rod 1, and the spring 25 is squeezed. As the sliding bolt 9 slides outward, the grooves 26 on both sides of its outer wall will be in the position of the retaining groove 10. Then, the guide plate 23 at the bottom of the adjusting rod 2 is aligned with the retaining groove 10 and inserted. When the lower side of the inner wall of the irregular groove 24 passes the grooves 26 on both sides, it will slide down against the inner wall of the grooves 26 until the guide plate 23 is fully inserted into the retaining groove 10. Then, the pressure plate 7 is released. Through the elastic potential energy of the spring 25, the sliding bolt 9 is reset. At the same time, the complete part of the outer wall of the sliding bolt 9 will slide into the upper side of the inner wall of the irregular groove 24 and form a limiting effect with the guide plate 23, thereby realizing the assembly between the bottom rod 1 and the adjusting rod 2.

[0037] Next, assemble the shelf 4 onto the front end of the adjusting rod 2, insert the insert 31 on the rear side of the shelf 4 into the corresponding height slot 3, and simultaneously press the push bolt 29 to slide it inside the hollow cylinder 22, causing the disc 28 to compress the spring 30, thereby moving the fitting block 27 away from one end of the hollow cylinder 22 until the insert 31 is fully inserted into the slot 3. Then, release the push bolt 29, and under the elastic action of the spring 30, the fitting block 27 will return to its original position and lock into the blocking groove 32, thus enabling the right-side insert block to be inserted. The limit of 31 completes the assembly of shelf 4. Repeat the above steps to complete the assembly of the other shelf 4. If it is necessary to adjust the distance between the two shelves 4, simply press the push bolt 29 so that the interlocking block 27 is pushed away from the grid groove 32, which will release the limit of the right side insert 31. Then, pull the shelf 4 out from the front end of the adjusting rod 2, select the appropriate height slot 3, and then reinstall it according to the above steps. This also realizes the adjustable distance of the shelf 4.
