Description

Technical Field

[0001] This application relates to the field of cabinet technology, and in particular to a handle-free cabinet. Background Technology

[0002] Traditional cabinet designs generally rely on protruding or recessed handles as the point of leverage for opening cabinet doors. While handles are functionally indispensable, they often affect the overall simplicity and smoothness of the appearance, increase cleaning dead spots, and pose a risk of bumps and knocks. With the popularity of modern minimalist design style and consumers' increasing demand for integrated and clean home spaces, handle-free (also known as handle-less or invisible handle) cabinet technology has emerged and developed rapidly.

[0003] Chinese utility model patent application No. 202121303031.6—a handle-free integrated cabinet structure—comprises a cabinet body, at least one door panel, and at least one set of connecting components. The cabinet body has an open receiving cavity. Each set of connecting components includes a profile, a sliding member, and a locking member. The sliding member can slide within the profile. One end of the locking member is connected to the sliding member, and the other end is connected to the cavity wall to fix the profile at the opening of the receiving cavity. The door panel opens and closes with the receiving cavity and is located above or below the corresponding profile. The side of the door panel facing the profile has a first inclined surface, and the side of the profile facing the door panel has a second inclined surface. The first and second inclined surfaces are arranged parallel to or abut against each other to form an insertion space between the first inclined surface and the profile for human hand insertion. Since there is no need to cut grooves in the cabinet body, the cabinet structure is more integrated; at the same time, the connecting components can be directly installed in the receiving cavity, simplifying the installation structure and process, and greatly reducing the cost of grooving.

[0004] Regarding the connecting components in the aforementioned patent, when the height of an item is higher than the height of the door panel but lower than the effective height from the bottom of the drawer to the bottom of the top panel, the top of the item will interfere with part of the connecting components during the closing process after the drawer is placed in it. The drawer cannot be fully closed, and the door panel is in an open state. To avoid interference, users may place the item in the drawer in a different direction. However, this may take up more space in the drawer, thereby reducing space utilization and failing to meet users' needs for efficient use of cabinet storage space. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a handle-free cabinet, addressing the issue that existing handle-free cabinet connecting components reduce space utilization. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A handle-free cabinet includes: The cabinet has a cavity inside, and at least one storage frame is slidably disposed in the cavity, with a door panel fixedly connected to the storage frame; A connecting plate assembly includes a main board, an arc-shaped plate, a sliding rod, and an abutment plate. The abutment plate is fixedly connected to the lower end face of the sliding rod, and the outer end face of the abutment plate is in contact with the inner end face of the door panel. The sliding rod is slidably connected to the arc-shaped plate, and the side end face of the arc-shaped plate is fixedly connected to the main board. Both ends of the main board are fixedly connected to the two inner side walls of the cabinet.

[0006] Furthermore, a first groove is formed on the lower end face of the motherboard, and the sliding rod is slidably connected to the first groove. A second groove and a third groove are formed on the inner walls on both sides of the first groove, and the third groove and the second groove are on the same horizontal line.

[0007] Furthermore, a first spring is fixedly provided on the inner wall of the second groove, and a first stop block is fixedly connected to the other end of the first spring. The first stop block is slidably connected to the first groove. A second spring is provided in the third groove, and a second stop block is fixedly connected to the other end of the second spring. The second stop block is slidably connected to the second groove.

[0008] Furthermore, the first stop and the second stop are provided with a first inclined surface facing each other, and the upper sides of the sliding rod are provided with a second inclined surface.

[0009] Furthermore, a first guide post is fixedly provided on the end face of the first stop block connected to the first spring, and the first guide post is located inside the first spring. A second guide post is fixedly provided on the end face of the second stop block connected to the second spring, and the second guide post is located inside the second spring.

[0010] Furthermore, a limiting block is fixedly provided at the lower end of the inner wall on both sides of the first groove, and the limiting block is provided with a third inclined surface.

[0011] Furthermore, a mounting base is slidably connected to the outer end face of the motherboard, and the mounting base is connected to the two inner side walls of the cabinet.

[0012] Furthermore, the outer end face of the arc-shaped plate is an arc-shaped surface.

[0013] The beneficial effects of this utility model are as follows: By setting an arc-shaped plate, a sliding rod, and an abutment plate, the abutment plate is lifted upward, causing the sliding rod to slide upward along the first groove. After the upper part of the sliding rod passes the first stop and the second stop and reaches the top of the first groove, the first stop and the second stop automatically clamp the lower part of the sliding rod under the action of the first spring and the second spring. The sliding rod is stably placed in the first groove, and the upper surface of the abutment plate is in contact with the lower surface of the main plate. The traditional connecting plate assembly is divided into an arc-shaped plate and an abutment plate. The abutment plate is set to be liftable, which can effectively reduce the interference between the top of the item and the traditional connecting assembly when the door is closed, increase the freedom of item placement, and thus effectively improve the space utilization of the storage frame.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: like Figures 1-2 As shown, a handle-free cabinet includes a cabinet body 1, with a cavity 2 inside the cabinet body 1. At least one storage frame 3 is slidably disposed in the cavity 2, and the storage frame 3 is fixedly connected to a door panel 4. A connecting plate assembly 5 is also fixedly disposed inside the cabinet body 1. The connecting plate assembly 5 includes a main plate 51, an arc-shaped plate 52, a sliding rod 53, and an abutment plate. The abutment plate is fixedly connected to the lower end face of the sliding rod 53, and the outer end face of the abutment plate is in contact with the inner end face of the door panel 4. The sliding rod 53 is slidably connected to the arc-shaped plate 52, and the side end face of the arc-shaped plate 52 is fixedly connected to the main plate 51. Both ends of the main plate 51 are fixedly connected to the two inner side walls of the cabinet body 1. This design divides the traditional connecting plate assembly 5 into an arc-shaped plate 52 and an abutment plate. The abutment plate is designed to be height-adjustable, which can effectively reduce the interference between the top of the items and the traditional connecting assembly when the door panel 4 is closed, increase the freedom of item placement, and thus effectively improve the space utilization rate of the storage frame 3.

[0023] like Figure 7 As shown, when the door panel 4 is in contact with the abutment plate (i.e., the door panel 4 is closed), a handle groove 20 is formed between the door panel 4 and the arc plate 52, and the user can pull the door panel 4 outward through the handle groove 20.

[0024] like Figures 3-4 As shown, it should be noted that the lower end face of the main board 51 has a first groove 6, and the sliding rod 53 is slidably connected to the first groove 6. The inner walls on both sides of the first groove 6 have a second groove 7 and a third groove 8, respectively, and the third groove 8 and the second groove 7 are on the same horizontal line. A first spring 9 is fixedly installed on the inner wall of the second groove 7, and a first stop block 10 is fixedly connected to the other end of the first spring 9. The first stop block 10 is slidably connected to the first groove 6. A second spring 11 is installed in the third groove 8, and a second stop block 12 is fixedly connected to the other end of the second spring 11. The second stop block 12 is slidably connected to the second groove 7. This structure is mainly used for automatically clamping the sliding rod 53.

[0025] In use, pushing the abutment plate upwards causes the sliding rod 53 to move upwards along the inner wall of the first groove 6. When the sliding rod 53 reaches contact with the first stop 10 and the second stop 12, pushing the abutment plate upwards continues the upward movement of the sliding rod 53. During this upward movement, the upper part of the sliding rod 53 drives the first stop 10 to move to the left along the inner wall of the first groove 6. The movement of the first stop 10 compresses the first spring 9, while the second stop 12 moves to the right along the inner wall of the second groove 7. The movement of the second stop 12 will cause the second spring 11 to be compressed. When the upper part of the sliding rod 53 is disengaged from the first stop 10 and the second stop 12, the first spring 9 and the second spring 11 will release their elastic force. The elastic force released by the first spring 9 will drive the first stop 10 to move to the right along the inner wall of the first groove 6, and the elastic force released by the second spring 11 will drive the second stop 12 to move to the left along the inner wall of the second groove 7, until the first stop and the second stop 12 clamp and fix the lower part of the sliding rod 53, thus completing the upward fixation of the abutment plate.

[0026] Furthermore, the first stop 10 and the second stop 12 are provided with a first inclined surface 13 facing each other, and the upper sides of the sliding rod 53 are provided with a second inclined surface 14; this structure facilitates the sliding rod 53 to simultaneously push the first stop 10 into the first groove 6 and the second stop 12 into the second groove 7.

[0027] It should be noted that a first guide post 15 is fixedly provided on the end face of the first stop 10 connected to the first spring 9, and the first guide post 15 is located inside the first spring 9. A second guide post 16 is fixedly provided on the end face of the second stop 12 connected to the second spring 11, and the second guide post 16 is located inside the second spring 11. The main purpose of this structure is to play a guiding role, reduce the risk of deformation of the first spring 9 and the second spring 11, and improve the service life of the first spring 9 and the second spring 11.

[0028] Furthermore, a limiting block 21 is fixedly provided at the lower end of the inner wall on both sides of the first groove 6, and the limiting block 21 is provided with a third inclined surface 17; the setting of this structure serves to limit the sliding rod 53 and prevent the sliding rod 53 from being pulled out of the first groove 6 when the abutment plate is pulled down.

[0029] It should be noted that the outer end face of the main board 51 is slidably connected to the mounting base 18, and the mounting base 18 is connected to the two inner side walls of the cabinet 1. The mounting base 18 is mainly used to fix the connecting plate assembly 5 to the cabinet 1. The mounting base 18 is fixedly connected to the inner wall of the cabinet 1 by several screws.

[0030] It should be noted that the outer end face of the arc plate 52 is an arc surface 19. This structure is designed to prevent the user's hand from being scratched.

[0031] The working principle and process of this utility model are as follows: When the height of the item to be placed is higher than the height of the door panel 4 but lower than the inner bottom surface to the inner end surface of the top panel of the storage frame 3, the door panel 4 is pulled out through the handle groove 20, and the abutment plate is pushed upward. The abutment plate will drive the sliding rod 53 to move upward along the inner wall of the first groove 6. When the sliding rod 53 moves to contact the first stop 10 and the second stop 12, the abutment plate is pushed upward again, and the sliding rod 53 continues to move upward. During the upward movement of the sliding rod 53, the upper part of the sliding rod 53 will drive the first stop 10 to move to the left along the inner wall of the first groove 6. The first guide post 15, which is fixedly connected to the first stop 10, moves to the left along with the first stop 10. The movement of the first stop 10 will drive the first spring 9 to compress. At the same time, the second stop 12 moves to the right along the inner wall of the second groove 7. The second guide post 16, which is fixedly connected to the second stop 12, moves to the right along with the second stop 12. The movement of the second stop 12 will drive the second spring 11 to compress. When the upper part of the sliding rod 53 disengages from the first stop 10 and the second stop 12, the first spring 9 and the second spring 11 will release their elastic force. The elastic force released by the first spring 9 will drive the first stop 10 to move to the right along the inner wall of the first groove 6. The first guide post 15, which is fixedly connected to the first stop 10, will move to the right along with the first stop 10. The elastic force released by the second spring 11 will drive the second stop 12 to move to the left along the inner wall of the second groove 7. The second guide post 16, which is fixedly connected to the second stop 12, will move to the left along with the second stop 12, until the first stop and the second stop 12 clamp and fix the lower part of the sliding rod 53, completing the upward fixation of the abutment plate. Then, place the item into the storage frame 3 and push the storage frame 3 with the item into the cavity 2 until the item has completely passed the main board 51. Then, pull the abutment plate down to the initial position and finally close the door panel 4 completely (i.e., the inner end face of the door panel 4 contacts and connects with the outer end face of the abutment plate). The working process of pulling down the abutment plate: Pulling down the abutment plate will cause the sliding rod 53 to move downward along the inner wall of the first groove 6. When the sliding rod 53 moves to contact the first stop 10 and the second stop 12, continue pulling down the abutment plate. The sliding rod 53 continues to move downward. During the downward movement of the sliding rod 53, the upper part of the sliding rod 53 will drive the first stop 10 to move to the left along the inner wall of the first groove 6. The first guide post 15, which is fixedly connected to the first stop 10, moves to the left along with the first stop 10. The movement of the first stop 10 will drive the first spring 9 to be compressed. At the same time, the second stop 12 moves to the right along the inner wall of the second groove 7. The second guide post 15, which is fixedly connected to the second stop 12, moves to the right. 6. As the second stop 12 moves to the right, the movement of the second stop 12 will cause the second spring 11 to be compressed. When the upper part of the sliding rod 53 disengages from the first stop 10 and the second stop 12, the first spring 9 and the second spring 11 will release their elastic force. The elastic force released by the first spring 9 will drive the first stop 10 to move to the right along the inner wall of the first groove 6, and the elastic force released by the second spring 11 will drive the second stop 12 to move to the left along the inner wall of the second groove 7. The first spring 9 and the second spring 11 will return to their normal state (neither compressed nor stretched) until the limiting block 21 blocks the sliding rod 53. At this time, the second inclined surface 14 of the sliding rod 53 contacts and connects with the third inclined surface 17 of the limiting block 21.
