Description

Technical Field

[0001] This utility model relates to the field of kitchen storage equipment technology, and more specifically, to a lower dish basket assembly with a sliding rail. Background Technology

[0002] As a core component of modern kitchen storage systems, the lower dish rack is made of metal or plastic with a mesh-like structure. It is fitted into cabinets or dishwashers via a precisely designed guide rail system on both sides. Its functional design balances load-bearing capacity and space utilization, stably supporting the stacking of various irregularly shaped tableware such as bowls, plates, and cups. The bottom drainage holes allow for draining, while the sliding mechanism of the guide rails enables smooth pulling. The overall design forms a modular solution integrating storage, draining, and retrieval, effectively improving the efficiency and tidiness of kitchen workflows.

[0003] Existing lower dish rack installation methods employ a fixed three-section sliding rail structure, achieving storage and retrieval functions through the sliding rail pull-out mechanism. However, this design has inherent limitations, permanently locking the height of the lower dish rack during the initial installation stage. This prevents flexible adjustment of the storage space for different sized tableware and makes it difficult to adapt to personalized user scenarios. This static, fixed mode results in both limited space utilization and a poor user experience. Therefore, we have made an improvement by proposing a lower dish rack assembly with sliding rails. Summary of the Invention

[0004] The purpose of this utility model is that the height of the lower bowl basket is permanently locked during the initial installation stage, which makes it impossible to flexibly adjust the storage space for tableware of different sizes and makes it difficult to adapt to the user's personalized usage scenarios. This static fixed mode leads to the problem of limited space utilization and user experience.

[0005] To achieve the above-mentioned objectives, this invention provides a lower basket assembly with a slide rail to improve the aforementioned problems.

[0006] The application is as follows: A lower basket assembly with sliding rails includes two sets of uprights, which are arranged in pairs. Each set of uprights is equipped with a lifting component. Each of the two lifting components has a three-section rail installed at its upper end. The upper ends of the two three-section rails are jointly fixedly installed with the lower basket body. Each of the two lifting components has two fixing components installed to prevent the lower basket body from moving.

[0007] As a preferred technical solution of this application, the lifting assembly includes a lifting groove, and two lifting grooves are provided. The two lifting grooves are respectively opened on one side of two columns. A lifting block is slidably connected in each of the two lifting grooves. A lifting plate is fixedly connected between the two lifting blocks. A limiting component for fixing the lifting plate is installed in the lifting plate.

[0008] As a preferred technical solution of this application, the limiting component includes a rotating cavity, a sliding groove, and a fixing plate. The rotating cavity is opened inside one side of the lifting plate. There are two sliding grooves and two fixing plates. The two sliding grooves are symmetrically opened on one side of the lifting plate, and the two fixing plates are respectively fixedly connected to one side wall of the two columns.

[0009] As a preferred technical solution of this application, a set of limiting grooves arranged in an upper and lower array are provided on the side wall of the two fixed plates near the lifting plate. Limiting rods are slidably connected to the inner walls of the two sliding grooves. The two limiting rods are respectively engaged with the two sets of limiting grooves. One-way screws are rotatably connected to the inner walls of the two sliding grooves away from the fixed plates. The two one-way screws are respectively threaded into the two limiting rods.

[0010] As a preferred technical solution of this application, a worm and two worm wheels are rotatably connected to the inner wall of the rotating cavity. The two worm wheels mesh with the worm. The output ends of the two worm wheels penetrate the inner wall of one side of the rotating cavity, and the output ends of the two worm wheels are respectively fixedly connected to one end of two one-way screws. A knob is rotatably connected to one side of the lifting plate. The output end of the knob penetrates the lifting plate and is fixedly connected to one end of the worm.

[0011] As a preferred technical solution of this application, the fixing component includes a top rod that passes through the lifting plate and is slidably disposed in the sliding groove. The lower end face of the top rod is inclined and the inclined surface of the top rod faces the limiting rod.

[0012] As a preferred technical solution of this application, a friction plate is fixedly connected to the upper end of the top rod, a blocking block is fixedly connected to the lower side wall of the top rod near the rotating cavity, a limiting post is fixedly connected to the upper side of the lifting plate, the blocking block is slidably sleeved outside the limiting post, and the friction plate is located on the lower side of the lower bowl basket body.

[0013] As a preferred technical solution of this application, each of the two side walls of the column is fixedly connected with a mounting block at the four corners, and a fixing screw is threaded through the middle of the mounting block.

[0014] As a preferred technical solution of this application, a guide rod is fixedly connected to the inner wall of each of the lifting grooves, and the lifting block is slidably sleeved on the outside of the guide rod.

[0015] As a preferred technical solution of this application, anti-slip plates are fixedly connected to both sides of the lower end of the lower bowl basket body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: To address the problem that the height of the lower dish rack in existing technologies is permanently locked during the initial installation stage, making it impossible to flexibly adjust the storage space for tableware of different sizes and adapt to personalized user scenarios, resulting in limitations on both space utilization and user experience due to this static and fixed mode, this application utilizes a lifting component to adjust the height of the three-section rail and the lower dish rack itself. This allows for height adjustment of the lower dish rack, enabling users to easily adjust its position according to tableware size and storage needs, significantly improving the flexibility and space utilization of kitchen storage. When adjusting the height of the lower dish rack using the lifting component, the fixing component locks the lower dish rack itself, effectively ensuring the stability and safety of the adjustment process and preventing displacement or accidental slippage of the lower dish rack due to external forces or mechanical vibrations, thereby improving the operational accuracy and reliability of the overall structure.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background section, the height of the lower dish rack is permanently locked during the initial installation stage. This makes it impossible to flexibly adjust the storage space for different sizes of tableware and makes it difficult to adapt to personalized user scenarios. This static and fixed mode results in a double limitation on space utilization and user experience.

[0021] To solve this technical problem, this utility model provides a lower dish basket assembly with a sliding rail, which is used for the layered storage of tableware in the kitchen.

[0022] For details, please refer to Figures 1-5 The lower bowl basket assembly with sliding rails specifically includes: Two sets of uprights 1, each set of uprights 1 is paired up, and each set of uprights 1 is equipped with a lifting component 2. Each of the two lifting components 2 is equipped with a three-section rail 3 at its upper end. The lower basket body 4 is fixedly installed on the upper end of the two three-section rails 3. Each of the two lifting components 2 is equipped with two fixing components 5 to prevent the lower basket body 4 from moving.

[0023] The sliding rail lower dish basket assembly provided by this utility model allows for height adjustment of the three-section rail 3 and the lower dish basket body 4 via the lifting component 2. This enables height adjustment of the lower dish basket body 4, allowing users to easily adjust its position according to the size of the tableware and storage needs. This significantly improves the flexibility and space utilization of kitchen storage. When adjusting the height of the lower dish basket body 4 using the lifting component 2, the fixing component 5 locks the lower dish basket body 4, effectively ensuring the stability and safety of the lower dish basket body 4 during the adjustment process. This prevents displacement or accidental slippage of the lower dish basket body 4 due to external forces or mechanical vibrations, thereby improving the operational accuracy and reliability of the overall structure.

[0024] It is worth noting that the three-section rail 3 is an existing technology, consisting of three nested rails: an outer rail, a middle rail, and an inner rail. It achieves smooth and low-resistance sliding by precisely arranged ball bearings between the rails. The outer rail is fixed to the upper end of the lifting plate 203 on the lifting assembly 2. The middle rail slides in conjunction with the outer rail. The front end of the inner rail is rigidly connected to the lower basket body 4 through a connector. When the lower basket body 4 is pulled out horizontally, the middle rail slides along the outer rail to its maximum stroke, and then the inner rail fixed to the end of the middle rail continues to slide out synchronously, so that the lower basket body 4 is completely separated from the cabinet frame to achieve full-size sliding.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figures 1-4 A lower basket assembly with sliding rails includes two sets of uprights 1, arranged in pairs. Each set of uprights 1 has a lifting assembly 2 installed inside. Each lifting assembly 2 has a three-section rail 3 installed at its upper end. The upper ends of the two three-section rails 3 are jointly fixedly mounted on the lower basket body 4. Each lifting assembly 2 has two fixing components 5 installed inside to prevent the lower basket body 4 from moving. Each lifting assembly 2 includes a lifting groove 201, with two grooves 201 respectively located on one side of each of the two uprights 1. Each lifting groove 201 has a slidably connected lifting block 202. The two lifting blocks 202 are jointly fixedly connected to a lifting plate 203. The lifting plate 203 has a limiting component installed inside to fix it. When the height of the lower dish basket body 4 needs to be adjusted, the user operates the knob 212, causing the worm gear 210 to rotate. The worm wheel 211 located in the rotating cavity 204 rotates, which in turn causes the one-way screw 209 to rotate. The limiting rod 208 moves out of the limiting groove 207. Then, the user pushes the lifting plate 203, which allows the lifting block 202 to slide in the lifting groove 201, thereby adjusting the height of the lower dish basket body 4. After adjusting to the specified height, the user reverses the knob 212, which moves the limiting rod 208 into the corresponding limiting groove 207, thus fixing the lower dish basket body 4. The user can easily adjust the position of the lower dish basket body 4 according to the size of the tableware and storage needs, significantly improving the flexibility and space utilization of kitchen storage.

[0029] Furthermore, such as Figures 3-4As shown, the limiting assembly includes a rotating cavity 204, a sliding groove 205, and a fixing plate 206. The rotating cavity 204 is located inside one side of the lifting plate 203. Two sliding grooves 205 and two fixing plates 206 are provided. The two sliding grooves 205 are symmetrically located on one side of the lifting plate 203. The two fixing plates 206 are respectively fixedly connected to one side wall of the two columns 1. A set of vertically arranged limiting grooves 207 are provided on the side wall of the two fixing plates 206 near the lifting plate 203. Limiting rods 208 are slidably connected to the inner walls of both sliding grooves 205. The two limiting rods 208 respectively engage with the two sets of limiting grooves 207. The inner walls of the two sliding grooves 205 away from the fixing plate 206 are rotatably connected to... Two one-way screws 209 are threadedly connected to two limiting rods 208 respectively. Since the one-way screws 209 and the limiting rods 208 are threadedly connected, when the one-way screws 209 rotate, the limiting rods 208 can move into the limiting grooves 207 to form a physical lock, so that the lifting plate 203 can be stably fixed at the specified height. In addition, the two limiting rods 208 and two sets of limiting grooves 207 are set to fix the lifting plate 203. The double symmetrical distribution of the limiting rods 208 not only effectively counteracts the deflection torque that may be generated by single-point force, but also eliminates the displacement risk of the lifting plate 203 under load through multi-directional constraints, significantly improving the structural stability and operational safety of the lower basket body 4.

[0030] Furthermore, such as Figure 4 As shown, a worm 210 and two worm wheels 211 are rotatably connected to the inner wall of the rotating cavity 204. Both worm wheels 211 mesh with the worm 210. The output ends of the two worm wheels 211 penetrate one side of the inner wall of the rotating cavity 204, and are respectively fixedly connected to one end of two one-way screws 209. A knob 212 is rotatably connected to one side of the lifting plate 203. The output end of the knob 212 penetrates the lifting plate 203 and is fixedly connected to one end of the worm 210. By rotating the knob 212, the worm 210 can be rotated, which drives the worm wheels 211 to rotate. The worm wheels 211 can then drive the one-way screws 209 to rotate. By utilizing the mechanical self-locking effect of the worm wheels 211 and the worm 210, the risk of slippage of the limit rod 208 caused by the reverse rotation of the one-way screw 209 under load is eliminated, thereby ensuring the stability of the fixed structure of the limit rod 208 and the limit groove 207.

[0031] Example 2 further optimizes the lower basket assembly with slide rail provided in Example 1, specifically, as follows: Figure 2 and Figure 5As shown, the fixing component 5 includes a top rod 501, which passes through the lifting plate 203 and is slidably disposed within the sliding groove 205. The lower end face of the top rod 501 is inclined, and the inclined surface of the top rod 501 faces the limiting rod 208. By setting the fixing component 5, when the user needs to adjust the height of the lower basket body 4, when the limiting rod 208 is moved out of the limiting groove 207, the limiting rod 208 slides within the sliding groove 205 and approaches the position of the rotating cavity 204. When the limiting rod 208 contacts the top rod 501... After the lower end of 01 is inclined, the inclined surface of the push rod 501 decomposes the horizontal thrust, so that the push rod 501 is subjected to a vertical upward thrust. The push rod 501 rises, and the friction plate 502 at the upper end of the push rod 501 will abut against the lower end of the lower bowl basket body 4, thereby achieving temporary friction fixation of the lower bowl basket body 4. This can effectively ensure the stability and safety of the lower bowl basket body 4 during the adjustment process, and avoid the lower bowl basket body 4 from shifting or accidentally slipping on the three-section rail 3 due to external force or mechanical vibration, thereby improving the operational accuracy and reliability of the overall structure.

[0032] Furthermore, such as Figure 5 As shown, a friction plate 502 is fixedly connected to the upper end of the top rod 501. A blocking block 503 is fixedly connected to the lower side wall of the top rod 501 near the rotating cavity 204. A limiting post 504 is fixedly connected to the upper side of the lifting plate 203. The blocking block 503 is slidably sleeved on the outside of the limiting post 504. The friction plate 502 is located on the lower side of the lower basket body 4. The friction plate 502 can increase the friction with the lower end of the lower basket body 4, so that the lower basket body 4 can be stably fixed and prevent the lower basket body 4 from sliding on the three-section rail 3 when adjusting the height. The limiting post 504 limits the lifting and lowering of the top rod 501. On the one hand, it can prevent the top rod 501 from sliding out of the lifting plate 203. On the other hand, it can make the top rod 501 descend beyond its travel under its own weight, so that after the top rod 501 descends, only the inclined surface of the top rod 501 can slide into the sliding groove 205.

[0033] Furthermore, such as Figure 5 As shown, anti-slip plates 9 are fixedly connected to both sides of the lower end of the lower bowl basket body 4, so that the friction plate 502 can more stably fix the lower bowl basket body 4, further improving the stability of the lower bowl basket body 4.

[0034] Example 3 further optimizes the lower basket assembly with slide rail provided in Example 1, specifically, as follows: Figure 1 and Figure 2 As shown, each column 1 has a mounting block 6 fixedly connected to the four corners of its two side walls. The mounting block 6 has a threaded fixing screw 7 through the middle. When installing the column 1, the fixing screw 7 can be used to fix the column 1 in the designated position, making installation and disassembly convenient and making the fixing of the column 1 more stable.

[0035] Furthermore, such as Figure 2 As shown, a guide rod 8 is fixedly connected to the inner wall of each lifting groove 201, and the lifting block 202 is slidably sleeved on the outside of the guide rod 8. The guide rod 8 limits the lifting block 202 to ensure that the lifting block 202 can slide up and down stably in the lifting groove 201.

[0036] The usage process of the lower bowl basket assembly with slide rail provided by this utility model is as follows: When the height of the lower dish basket body 4 needs to be adjusted, the user operates the knob 212 to rotate the worm gear 210. The worm wheel 211 located in the rotating cavity 204 rotates, which causes the one-way screw 209 to rotate. The limiting rod 208 moves out of the limiting groove 207. Then, the user pushes the lifting plate 203, which causes the lifting block 202 to slide in the lifting groove 201, thereby adjusting the height of the lower dish basket body 4. After adjusting to the specified height, the user reverses the knob 212, which causes the limiting rod 208 to move into the corresponding limiting groove 207, thereby fixing the lower dish basket body 4. The user can easily adjust the position of the lower dish basket body 4 according to the size of the tableware and storage needs, which significantly improves the flexibility and space utilization of kitchen storage. When the user needs to adjust the height of the lower basket body 4, as the operating limit rod 208 moves out of the limit groove 207, the limit rod 208 slides in the sliding groove 205 and moves closer to the rotating cavity 204. When the limit rod 208 contacts the lower inclined surface of the top rod 501, the inclined surface of the top rod 501 decomposes the horizontal thrust, so that the top rod 501 is subjected to a vertical upward thrust. The top rod 501 rises, and the friction plate 502 at the upper end of the top rod 501 will abut against the lower end of the lower basket body 4, thereby achieving temporary friction fixation of the lower basket body 4. This can effectively ensure the stability and safety of the lower basket body 4 during the adjustment process, and prevent the lower basket body 4 from shifting on the three-section rail 3 or accidentally slipping due to external force or mechanical vibration, thereby improving the operational accuracy and reliability of the overall structure.
