Description

Technical Field

[0001] This utility model relates to the field of beverage rack technology, and in particular to a plastic-coated iron beverage rack. Background Technology

[0002] Plastic-clad metal beverage racks are a type of beverage rack that combines plastic and metal materials, typically used for storing and displaying beverage bottles, cans, etc. This design combines the lightweight nature of plastic with the sturdiness of metal, making it both durable and easy to move.

[0003] Household beverage racks are usually designed to be small to save space, consisting of two layers: a bottom layer and a top layer. However, once the beverage rack is manufactured, the space between the bottom and top layers is fixed. This means that taller beverages cannot be placed on the bottom layer or canned beverages cannot be stacked. If the space between the bottom and top layers is designed to be larger, it will increase the overall size of the beverage rack, resulting in low practicality and flexibility in use. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the space between the bottom and top layers of a beverage rack is fixed after the rack is manufactured. When it is necessary to place taller beverages or stack canned beverages at the bottom layer, it is impossible to fit them. If the space between the bottom and top layers is designed to be large, it will increase the overall volume of the beverage rack, resulting in low practicality and flexibility when using the beverage rack. Therefore, a plastic-coated iron beverage rack is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic-coated iron beverage rack, comprising a top plate and a bottom plate. Sleeves are fixedly connected to the four corners of the bottom of the top plate, and support rods are fixedly connected to the four corners of the top of the bottom plate. The sleeves are used to connect the top plate and the bottom plate by fitting onto the surface of the support rods. The support rods are used to support the sleeves and the top plate. Both the sleeves and the support rods are made of plastic-coated iron with an inner iron rod and an outer plastic shell. The outer surface of the support rod is provided with a positioning device to facilitate adjusting the position of the sleeves on the outer surface of the support rod and to fix the position of the sleeves.

[0006] Preferably, the positioning device includes a rectangular block and a protrusion. The top of the rectangular block has a groove. The protrusion is located at the bottom of the sleeve rod and is used to mate with the groove at the top of the rectangular block. The internal shape and size of the protrusion are adapted to the internal shape and size of the groove. Two sliding grooves are provided on one side of the support rod. A rectangular block is provided inside each of the two sliding grooves. The sliding grooves are used for sliding the rectangular block and for storing the rectangular block. A spring is provided inside the sliding groove to eject the rectangular block from the sliding groove. The spring is in a compressed state inside the sliding groove.

[0007] The aforementioned components achieve the following effect: When using the beverage rack, beverages are placed on the top and bottom plates for storage. When a higher beverage needs to be placed on the bottom plate, the top plate can be pulled to control the various sleeves at the bottom of the top plate to slide upwards on the surfaces of the various support rods at the top of the bottom plate. When the sleeve moves to the groove below the outer surface of the support rod, the compressed spring inside the groove pushes the rectangular block to slide outwards on the inner wall of the groove, extending the outer surface of the rectangular block out of the groove. At this time, the top plate is released, and a protrusion at the bottom of the sleeve will be locked in the groove at the top of the rectangular block. The rectangular blocks on the outer surfaces of the various support rods support the sleeve, causing the sleeve to rise a certain distance from the outer surface of the support rod. At this point, a higher beverage can be placed on top of the bottom plate. Pulling the sleeve upwards again moves it to the groove above the outer surface of the support rod. The rectangular blocks inside the groove support the sleeve again, raising the height of the sleeve and the top plate again, making it easier to stack canned beverages on the bottom plate.

[0008] Preferably, the positioning device further includes a T-shaped rod, which is disposed on one side of the rectangular block to control the movement of the rectangular block. Two T-shaped grooves are formed on one side of the support rod, one end of which communicates with the interior of the sliding groove, and the T-shaped rod is located inside the T-shaped groove.

[0009] The effect achieved by the above components is as follows: when it is necessary to completely fit the sleeve rod on the outer surface of the support rod to reduce the overall volume of the beverage rack, push the T-shaped rod at the T-shaped groove on the outer side of each support rod to control the T-shaped rod to slide inward on the inner wall of the T-shaped groove, drive the rectangular block to move into the slide groove and put the rectangular block back into the slide groove. Then move the sleeve rod to the slide groove to release the T-shaped block, and then let the sleeve rod slide on the outer surface of the support rod until the bottom end contacts the base plate.

[0010] Preferably, a rotating rod is provided at one end of the inner wall of the T-shaped groove, and two locking blocks are provided at one end of the rotating rod. The rotating rod rotates at one end of the inner wall of the T-shaped groove, and a keyway is provided on the outer surface of the T-shaped rod. The keyway is used to cooperate with the rotating rod to lock the position of the T-shaped rod and the rectangular block.

[0011] The effect achieved by the above components is as follows: When the sleeve rod is retracted, pulling the T-shaped block controls the movement of the rectangular block to retract the rectangular block into the slide groove. First, the rotating rod can be rotated to align the two locking blocks at one end of the rotating rod with the keyway on the outer surface of the T-shaped block. When the rectangular block is fully retracted into the slide groove, the keyway on the outer surface of the T-shaped rod will pass through the end of the rotating rod with the locking block. Then, rotating the rotating rod controls the rotation of the rotating rod to offset the two locking blocks at one end of the rotating rod from the groove of the keyway. The position of the T-shaped block and the rectangular block is restricted by the rotating rod, which makes it easier to retract the rectangular blocks on the outer surface of each support rod into the slide groove in sequence. When the sleeve rod is raised again, pushing the rotating rod to rotate will pop the rectangular block out of the slide groove by the spring.

[0012] Preferably, the top edge of the rectangular block is provided with a slope, and the slope side does not exceed one-third of the length of the rectangular block.

[0013] The effect achieved by the above components is as follows: by setting the top edge of the rectangular block as a slope, the sleeve rod moves upward on the outer surface of the support rod to half the height of the slide groove, and then most of the outer surface of the rectangular block can extend out of the slide groove, thus assisting the sleeve rod to rise.

[0014] Preferably, the top two sides of the base plate are provided with limiting devices. The limiting devices include a round rod, a pressure block, and a threaded ring. The bottom end of the round rod is fixed to both sides of the base plate for installing the threaded ring. The top two sides of the round rod are fixedly connected with protruding rods. The pressure block is fixed to the bottom end of the threaded ring by a collar. The bottom end of the collar has a groove adapted to the shape of the protruding rods on both sides of the top of the round rod. The threaded ring is threaded to the top of the round rod to control the movement of the collar on the outer surface of the round rod.

[0015] The effect achieved by the above components is as follows: when moving the beverage rack and when there is no need to adjust the distance between the bottom plate and the top plate, the threaded ring at the top of the round rod can be rotated on both sides of the bottom plate to move the threaded ring downward on the outer surface of the round rod, so that the pressure block on one side of the collar is located above the crossbar connecting the two sleeve rods. At the same time, the angle of the collar is controlled so that the groove at the bottom of the collar is locked on the outside of the two protrusions at the top of the round rod. Then, the threaded ring is rotated to make the threaded ring descend and press the pressure block on the crossbar connecting the two sleeve rods. This fixes the position of the sleeve rod on the outer surface of the support rod and the distance between the top plate and the bottom plate, and minimizes the possibility of the sleeve rod sliding on its own when moving the beverage rack.

[0016] Preferably, the outer surface of the threaded ring is provided with a plurality of protrusions, which are circumferentially distributed on the outer surface of the threaded ring.

[0017] The effect achieved by the above components is that by pressing the protrusion on the outer surface of the threaded ring with your hand, you can more easily control the rotation of the threaded ring and prevent your hand from slipping.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, a positioning device is provided. By connecting the support rod to the base plate and the sleeve rod to the top plate, the sleeve rod is fitted onto the surface of the support rod. Two grooves of different heights are provided on the outer surface of the support rod to facilitate adjustment of the position of the sleeve rod on the outer surface of the support rod. The position of the sleeve rod is fixed by rectangular blocks inside the grooves, thereby flexibly adjusting the distance between the base plate and the top plate. This allows for expansion of the longitudinal space above the base plate according to usage, improving the flexibility and practicality of the beverage rack during use. Attached Figure Description

[0028] Example 1, such as Figure 1-3 As shown, the plastic-coated iron beverage rack includes a top plate 1 and a bottom plate 5. Sleeve rods 4 are fixedly connected to the four corners of the bottom end of the top plate 1, and support rods 6 are fixedly connected to the four corners of the top end of the bottom plate 5. The sleeve rods 4 are used to connect the top plate 1 and the bottom plate 5 by fitting them onto the surface of the support rods 6. The support rods 6 are used to support the sleeve rods 4 and the top plate 1. Both the sleeve rods 4 and the support rods 6 are made of plastic-coated iron material with an iron rod inside and a plastic outer shell. The outer surface of the support rods 6 is provided with a positioning device 2 to facilitate the adjustment of the position of the sleeve rods 4 on the outer surface of the support rods 6 and to fix the position of the sleeve rods 4.

[0029] Reference Figure 1-5As shown, in this embodiment: the positioning device 2 includes a rectangular block 23 and a protrusion 21. A groove 25 is provided at the top of the rectangular block 23. The protrusion 21 is located at the bottom of the sleeve rod 4 and is used to mate with the groove 25 at the top of the rectangular block 23. The internal shape and size of the protrusion 21 are adapted to the internal shape and size of the groove 25. Two sliding grooves 22 are provided on one side of the support rod 6. A rectangular block 23 is installed inside each of the two sliding grooves 22. The sliding grooves 22 are used for sliding the rectangular block 23 and for storing it. A spring 24 is installed inside the sliding grooves 22 to eject the rectangular block 23 from the sliding grooves 22. The spring 24 is in a compressed state inside the sliding grooves 22. When using the beverage rack, beverages are placed on the top plate 1 and the bottom plate 5 for storage. When placing a higher beverage on the base plate 5, the top plate 1 can be pulled to control the various sleeve rods 4 at the bottom of the top plate 1 to slide upwards on the surfaces of the various support rods 6 at the top of the base plate 5. When the sleeve rod 4 moves to the groove 22 below the outer surface of the support rod 6, the compressed spring 24 inside the groove 22 will push the rectangular block 23 to slide outwards on the inner wall of the groove 22, extending the outer surface of the rectangular block 23 out of the groove 22. At this time, the top plate 1 is released, and a protrusion 21 at the bottom of the sleeve rod 4 will be stuck in the groove 25 at the top of the rectangular block 23. The rectangular blocks 23 on the outer surfaces of the various support rods 6 support the sleeve rod 4, causing the sleeve rod 4 to rise a certain distance on the outer surface of the support rod 6. At this time, a higher beverage can be placed on top of the base plate 5. Pulling the sleeve rod 4 again will raise the sleeve rod 4 to a higher position. 4. Move to the upper slide groove 22 on the outer surface of the support rod 6. The rectangular block 23 inside the slide groove 22 can support the sleeve rod 4 again, raising the height of the sleeve rod 4 and the top plate 1, making it easier to stack canned beverages on the bottom plate 5. The positioning device 2 also includes a T-shaped rod 27, which is set on one side of the rectangular block 23 to control the movement of the rectangular block 23. Two T-shaped grooves 26 are opened on one side of the support rod 6. One end of the T-shaped groove 26 is connected to the interior of the slide groove 22. The T-shaped rod 27 is located inside the T-shaped groove 26. When it is necessary to completely fit the sleeve rod 4 on the outer surface of the support rod 6 to reduce the overall volume of the beverage rack, push the T-shaped rod 27 at the T-shaped groove 26 on the outer side of each support rod 6 to control the T-shaped rod 27 to slide inward on the inner wall of the T-shaped groove 26, driving... The rectangular block 23 moves into the groove 22 and is then retracted into the groove 22. The sleeve rod 4 is then moved to the groove 22 to release the T-shaped block. The sleeve rod 4 then slides on the outer surface of the support rod 6 until its bottom end contacts the base plate 5. By setting the positioning device 2, the support rod 6 is connected to the base plate 5, and the sleeve rod 4 is connected to the top plate 1, allowing the sleeve rod 4 to fit onto the surface of the support rod 6. Two grooves 22 of different heights are set on the outer surface of the support rod 6 to facilitate adjustment of the position of the sleeve rod 4 on the outer surface of the support rod 6. The rectangular block 23 inside the groove 22 fixes the position of the sleeve rod 4, thereby flexibly adjusting the distance between the base plate 5 and the top plate 1. This allows for expansion of the longitudinal space above the base plate 5 according to usage, improving the flexibility and practicality of the beverage rack during use.

[0030] Reference Figure 2-6 As shown in this embodiment: a rotating rod 29 is provided at one end of the inner wall of the T-shaped groove 26, and two locking blocks are provided at one end of the rotating rod 29. The rotating rod 29 rotates at one end of the inner wall of the T-shaped groove 26. A keyway 28 is provided on the outer surface of the T-shaped rod 27. The keyway 28 is used to cooperate with the rotating rod 29 to lock the positions of the T-shaped rod 27 and the rectangular block 23. When the sleeve rod 4 is retracted, the T-shaped block is pulled to control the movement of the rectangular block 23. When the rectangular block 23 is retracted into the slide groove 22, the rotating rod 29 can be rotated first to align the two locking blocks at one end of the rotating rod 29 with the keyway 28 on the outer surface of the T-shaped block. When the rectangular block 23 is fully retracted into the slide groove 22, the keyway 28 on the outer surface of the T-shaped rod 27 will pass through the end of the rotating rod 29 where the locking blocks are provided. Then the rotating rod 29 is rotated to control the position of the rectangular block 23. Rotating the lever 29 causes the two locking blocks at one end of the lever 29 to be misaligned with the groove of the keyway 28. The lever 29 restricts the position of the T-shaped block and the rectangular block 23, making it easier to sequentially retract the rectangular blocks 23 on the outer surface of each support rod 6 into the slide groove 22. When raising the sleeve 4 again, pushing the lever 29 to rotate will cause the rectangular blocks 23 to pop out of the slide groove 22 via the spring 24. A slope is provided on one side of the top edge of the rectangular block 23, and the slope side does not exceed one-third of the length of the rectangular block 23. By setting the top edge of the rectangular block 23 as a slope, the sleeve 4 can move upward on the outer surface of the support rod 6 to half the height of the slide groove 22, after which most of the outer surface of the rectangular block 23 can extend out of the slide groove 22, assisting the sleeve 4 in rising.

[0031] Reference Figure 1 , Figure 3 and Figure 7As shown in this embodiment: Limiting devices 3 are provided on both sides of the top of the base plate 5. The limiting devices 3 include a round rod 31, a pressure block 34, and a threaded ring 35. The bottom end of the round rod 31 is fixed to both sides of the base plate 5 for mounting the threaded ring 35. The top two sides of the round rod 31 are fixedly connected with protruding rods 32. The pressure block 34 is fixed to the bottom end of the threaded ring 35 by a collar 33. The bottom end of the collar 33 has a slot adapted to the shape of the protruding rods 32 on both sides of the top of the round rod 31. The threaded ring 35 is threadedly connected to the top of the round rod 31 to control the movement of the collar 33 on the outer surface of the round rod 31. When the beverage rack is being moved and the distance between the base plate 5 and the top plate 1 does not need to be adjusted, the threaded ring 35 at the top of the round rod 31 can be rotated on both sides of the base plate 5 so that the threaded ring 35 faces the outer surface of the round rod 31. The collar 33 is moved downwards so that the pressure block 34 on one side of the collar 33 is above the crossbar connecting the two collar rods 4. At the same time, the angle of the collar 33 is controlled so that the groove at the bottom of the collar 33 is engaged with the two protrusions 32 at the top of the round rod 31. Then, the threaded ring 35 is rotated to lower the threaded ring 35 and press the pressure block 34 onto the crossbar connecting the two collar rods 4. This fixes the position of the collar rod 4 on the outer surface of the support rod 6 and the distance between the top plate 1 and the bottom plate 5, thus preventing the collar rod 4 from sliding on its own when moving the beverage rack. The outer surface of the threaded ring 35 is provided with several protrusions 36, which are distributed circumferentially on the outer surface of the threaded ring 35. By pressing the protrusions 36 on the outer surface of the threaded ring 35 with your hand, you can more easily control the rotation of the threaded ring 35 and prevent your hand from slipping.

[0032] Working principle: When handling or not using the beverage rack, rotate the threaded ring 35 at the top of the round rod 31 on both sides of the base plate 5 to move the threaded ring 35 downward on the outer surface of the round rod 31, so that the pressure block 34 on one side of the collar 33 is positioned above the crossbar connecting the two sleeve rods 4. At the same time, control the angle of the collar 33 so that the groove at the bottom of the collar 33 is engaged with the outside of the two protrusions 32 at the top of the round rod 31. Then continue to rotate the threaded ring 35 to lower the threaded ring 35 and press the pressure block 34 onto the crossbar connecting the two sleeve rods 4, thus aligning the sleeve rods 4 outside the support rod 6. The position of the surface and the distance between the top plate 1 and the bottom plate 5 are fixed. When using the beverage rack, beverages are placed on the top plate 1 and the bottom plate 5 for storage. When a higher beverage needs to be placed on the bottom plate 5, the top plate 1 can be pulled to control the various sleeve rods 4 at the bottom of the top plate 1 to slide upward on the surface of the various support rods 6 at the top of the bottom plate 5. When the sleeve rod 4 moves to the groove 22 below the outer surface of the support rod 6, the compressed spring 24 inside the groove 22 will push the rectangular block 23 to slide outward on the inner wall of the groove 22, thus pushing the outer surface of the rectangular block 23. When the top plate 1 is released, a protrusion 21 at the bottom of the sleeve rod 4 will engage with the groove 25 at the top of the rectangular block 23. The rectangular blocks 23 on the outer surfaces of each support rod 6 support the sleeve rod 4, causing it to rise a certain distance above the support rod 6. At this point, a beverage of higher height can be placed above the bottom plate 5. Pulling the sleeve rod 4 up again moves it to the upper part of the groove 22 above the support rod 6. The rectangular blocks 23 inside the groove 22 support the sleeve rod 4 again, allowing the sleeve rod 4 and the top plate 1 to be aligned. The height is increased again to facilitate the stacking of canned beverages at the base plate 5. When it is necessary to completely fit the sleeve rod 4 on the outer surface of the support rod 6 to reduce the overall volume of the beverage rack, push the T-shaped rod 27 at the T-shaped groove 26 on the outer side of each support rod 6 to control the T-shaped rod 27 to slide inward on the inner wall of the T-shaped groove 26, which will drive the rectangular block 23 to move into the slide groove 22 and put the rectangular block 23 back into the slide groove 22. Then move the sleeve rod 4 to the slide groove 22 to release the T-shaped block, and then slide the sleeve rod 4 on the outer surface of the support rod 6 until the bottom end contacts the base plate 5.
