Description

Technical Field

[0001] This utility model belongs to the field of dining table technology, and specifically relates to a dining table that is easy to adjust in height. Background Technology

[0002] The dining table is one of the most important pieces of furniture in a restaurant, mainly used for placing food and for eating.

[0003] Currently, Chinese utility model patent CN217986986U discloses a dining table with adjustable leg height. While existing dining tables offer partial height adjustment to accommodate people of different heights, this adjustment is limited to the entire table. In large dining rooms, such as those in canteens where several people sit at a single table, adjusting the overall height doesn't guarantee a comfortable fit for everyone, yet individual adjustments are not possible, thus failing to meet practical needs. Furthermore, existing dining tables experience significant wear and tear over extended use. While other parts of the table may remain undamaged, the tabletop, due to frequent placement of items and dusting, develops dents, easily accumulating dirt and bacteria, and negatively impacting its appearance. Utility Model Content

[0004] The purpose of this utility model is to provide a dining table that is easy to adjust in height. Its advantages are that the height of the dining table can be adjusted individually and the tabletop can be replaced.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a height-adjustable dining table, including a support plate, with connecting rods bolted to both sides of the support plate, a lifting rod slidably connected to the top of the connecting rod, a tabletop bolted to the top of the lifting rod, a first bevel gear rotatably connected inside the connecting rod, a second bevel gear rotatably connected to the connecting rod at the top of the first bevel gear, and a screw threadedly connected to the lifting rod at the top of the second bevel gear.

[0006] By adopting the above technical solution, multiple tabletops are installed on top of the support plate, allowing each tabletop to be independently height-adjusted. This enables the support plate to not only accommodate multiple diners simultaneously but also to be individually adjustable to suit different heights, enhancing practicality. Furthermore, by installing a detachable movable plate on top of the tabletop, which is secured by clips, only the movable plate needs to be replaced when it becomes severely worn. This not only prevents severe tabletop damage that could affect usability but also keeps replacement costs low, meeting actual usage needs.

[0007] The present invention is further configured such that: a movable plate is provided on the top of the tabletop; a pull rod that is inserted into the movable plate is slidably connected through both sides inside the tabletop; a fixed plate is fixedly sleeved on the surface of the pull rod; a locking block is welded to the top of the pull rod; and a slot that engages with the locking block is provided at the bottom of the movable plate.

[0008] The above technical solution facilitates the replacement of damaged desktops, preventing severe damage that could affect usability, while also keeping replacement costs low and meeting practical usage needs.

[0009] The present invention is further configured such that: the bottom of the fixed plate is slidably connected to a sliding plate sleeved with the pull rod, and the bottom of the sliding plate is bolted with a double-inserted spring fixedly connected to the table board.

[0010] Using the above technical solution, the fixed plate is moved downward by the pull rod, so that the fixed plate can push the sliding plate to overcome the elastic force of the reinforcing spring. At the same time, when the pull rod rotates, it will drive the fixed plate to slide on the top of the sliding plate. Thus, the rebound force of the reinforcing spring can drive the pull rod to automatically reset and insert into the interior of the movable plate.

[0011] The present invention is further configured such that: the bottom of the table board and both sides of the connecting rod are rotatably connected to turntables respectively bolted to the pull rod and the first bevel gear.

[0012] The above technical solution facilitates the rotation of the pull rod and the first bevel gear, making control operations easier.

[0013] The present invention is further configured such that: both sides of the bottom of the support plate are bolted with columns, and the bottom of the columns are bolted with a base plate.

[0014] By adopting the above technical solution, the ground area of ​​the dining table is increased, thereby improving the stability of the table's placement.

[0015] The present invention is further configured such that a partition plate for use with the table board is bolted to the top of the support plate.

[0016] By adopting the above technical solution, multiple tables can be used separately to prevent them from affecting the dining of people next to them.

[0017] The present invention is further configured such that: both sides of the bottom of the table are bolted with reinforcing plates welded to the lifting rod.

[0018] By adopting the above technical solution, the bottom of the tabletop is reinforced and supported, thereby improving its load-bearing capacity.

[0019] The present invention is further configured such that: both sides of the surface of the lifting rod are welded with limiting sliders that are slidably connected to the connecting rod.

[0020] By adopting the above technical solution, the sliding of the lifting rod is limited, thereby improving the stability of the table height adjustment.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By installing multiple tabletops on top of the support panel, each tabletop can be independently adjusted in height. This allows the support panel to not only accommodate multiple people dining simultaneously but also to be individually adjusted to suit different heights, thus improving practicality.

[0023] 2. By installing a detachable movable panel on top of the tabletop, which is secured to the top of the tabletop with clips, only the movable panel needs to be replaced when it becomes severely worn. This not only prevents serious damage to the tabletop and ensures usability, but also keeps replacement costs low, meeting practical usage needs. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2An adjustable-height dining table includes a support plate 1. Connecting rods 2 are bolted to both sides of the support plate 1. A lifting rod 3 is slidably connected to the top of the connecting rods 2. A tabletop 4 is bolted to the top of the lifting rod 3. A first bevel gear 5 is rotatably connected inside the connecting rods 2. A second bevel gear 6, rotatably connected to the connecting rods 2, meshes with the top of the first bevel gear 5. A screw 7, threadedly connected to the lifting rod 3, is bolted to the top of the second bevel gear 6. By installing multiple tabletops 4 on the top of the support plate 1, the height of each tabletop 4 can be independently adjusted from the top of the support plate 1. This allows the support plate 1 to not only accommodate multiple people dining simultaneously but also to be individually adjustable according to the height needs of different individuals, improving its practicality.

[0032] refer to Figure 1 , Figure 2 The support plate 1 has columns 18 bolted to both sides of its bottom, and a base plate 19 bolted to the bottom of each column 18. This increases the ground contact area of ​​the dining table and improves its stability.

[0033] refer to Figure 1 , Figure 2 A partition 20, which works in conjunction with the tabletop 4, is bolted to the top of the support plate 1. This allows multiple tabletops 4 to be used separately, preventing them from affecting the dining of people nearby.

[0034] refer to Figure 2 The bottom sides of the tabletop 4 are both bolted with reinforcing plates 17 welded to the lifting rod 3. This supports and reinforces the bottom of the tabletop 4, thereby improving its load-bearing capacity.

[0035] refer to Figure 2 Both sides of the lifting rod 3 are welded with limiting sliders 8 that are slidably connected to the connecting rod 2. These limit the sliding of the lifting rod 3, improving the stability of the height adjustment of the tabletop 4.

[0036] Brief description of the usage process: By rotating the first bevel gear 5 and the second bevel gear 6, the screw 7 rotates inside the lifting rod 3 and engages with the thread of the lifting rod 3. This causes the lifting rod 3 to slide upward inside the connecting rod 2, allowing multiple tabletops 4 to be independently adjusted in height on the top of the support plate 1.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4This is a height-adjustable dining table. A movable plate 9 is located at the top of the tabletop 4. Pull rods 10, which are inserted into the movable plate 9, slide through both sides of the tabletop 4. A fixed plate 11 is fitted onto the surface of the pull rod 10, and a locking block 13 is welded to the top of the pull rod 10. A slot 12 is provided at the bottom of the movable plate 9 to engage with the locking block 13. By installing a detachable movable plate 9 at the top of the tabletop 4, and securing it to the top of the tabletop 4 via the locking block 13, only the movable plate 9 needs to be replaced when it becomes severely worn. This not only prevents severe damage to the tabletop and ensures usability but also keeps replacement costs low, meeting practical usage needs.

[0039] refer to Figure 1 The bottom of the fixed plate 11 is slidably connected to a sliding plate 14 that is sleeved with the pull rod 10. The bottom of the sliding plate 14 is bolted with a double-insertion spring 15 that is fixedly connected to the table board 4. The pull rod 10 drives the fixed plate 11 to move downward, so that the fixed plate 11 can push the sliding plate 14 to overcome the elastic force of the double-insertion spring 15. At the same time, when the pull rod 10 rotates, it will drive the fixed plate 11 to slide on the top of the sliding plate 14. Thus, the rebound force of the double-insertion spring 15 can drive the pull rod 10 to automatically reset and insert into the movable plate 9.

[0040] refer to Figure 2 , Figure 4 The bottom of the tabletop 4 and both sides of the connecting rod 2 are rotatably connected to turntables 16, which are respectively bolted to the pull rod 10 and the first bevel gear 5. This facilitates rotation, driving the pull rod 10 and the first bevel gear 5 to rotate, and making control operations convenient.

[0041] Brief description of usage: By rotating the pull rod 10, the locking block 13 rotates 90° counterclockwise, causing the locking block 13 to slide inside the slot 12. Afterward, the pull rod 10 can slide out of the movable plate 9, allowing the movable plate 9 to be removed from the top of the support plate 1 for replacement. Simultaneously, pulling the pull rod 10 inserts it into the newly placed movable plate 9, causing the locking block 13 to slide into the slot 12. Then, rotating the pull rod 10 rotates the locking block 13 90° clockwise. At this point, the locking block 13 engages inside the slot 12, thus limiting the pull rod 10 and fixing the movable plate 9 to the top of the tabletop 4.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
