Description

Technical Field

[0001] This utility model relates to the technical field of drawer interlocking structure for chest of drawers, specifically to a drawer interlocking structure for chest of drawers. Background Technology

[0002] In today's home life, the chest of drawers is a type of furniture mainly used for storing items. It is widely popular due to its strong storage capacity and diverse designs, and is widely used in various spaces such as bedrooms, living rooms, and studies. Its main function is to store items, especially small items. It consists of multiple drawers arranged side by side, which makes it easy to classify, store, and retrieve items, meeting people's growing storage needs, improving the tidiness and utilization of space, and becoming an indispensable part of home furnishing. Existing chests of drawers come in a variety of styles, including English, Korean, and modern, which can meet the matching needs of different home decoration styles.

[0003] Currently, when using the chest of drawers, simply pull the drawer handle and the drawer will slide out along the slide rail; to close it, push it in the opposite direction. If you need to access items in multiple drawers at the same time, simply repeat the operation in sequence.

[0004] However, when using a chest of drawers, it may be necessary to retrieve items from multiple drawers. Since the drawers do not have an interlocking function, it is easy for the operator to open multiple drawers at the same time, which can cause the chest of drawers to become unstable and easily tip over, creating a safety hazard and affecting its service life. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an interlocking structure for the drawers of a chest of drawers, in order to solve the technical problem that when using a chest of drawers, it is necessary to take out items from multiple drawers. Since the drawers do not have an interlocking function, the operator can easily open multiple drawers at the same time, which can cause the chest of drawers to become unstable, easily tip over, and cause safety hazards, thus affecting its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drawer interlocking structure for a chest of drawers, comprising a chest of drawers body, a plurality of drawer bodies slidably connected to one end of the chest of drawers body, a dovetail groove fixedly connected to one side of the chest of drawers body, a plurality of sliders that fit into the drawer bodies slidably connected to the dovetail groove, a connecting block fixedly connected to one side of each drawer body, an unlocking device that fits into the connecting block installed on one side of the chest of drawers body, a fixing block fixedly connected to one side of each connecting block, a locking block slidably connected to one side of each connecting block, and the connecting block and the locking block are connected by a set of first springs, one end of a connecting rod rotatably connected to one side of each slider, the other end of the set of connecting rods being connected by a pivot, and the top of the dovetail groove being connected to the topmost slider by a second spring.

[0007] By adopting the above technical solution, when it is necessary to open one of the drawer bodies, the drawer body can be gently pushed inward first, so that the bottom of the rotating shaft contacts the side of the locking block away from the fixed block and squeezes the locking block, moving downward until the bottom of the rotating shaft smoothly enters between the fixed block and the locking block. Then, the drawer body is pushed inward, and the fixed block moves synchronously with the connecting block, pushing the rotating shaft to move. The slider can then slide in the dovetail groove through the linkage transmission, compressing the second spring. Therefore, the other sliders are locked due to the structural linkage and cannot move, realizing the interlocking of other drawer bodies and thus preventing them from being opened. This avoids the instability and loss of balance caused by multiple drawer bodies being opened at the same time, which could easily cause the drawer body to tip over and cause danger. It can also extend the service life of the drawer body and help improve the stability and safety of the drawer body.

[0008] The present invention is further configured such that several sets of guide rails that fit with the drawer body are installed on both sides inside the main body of the cabinet, and a guide block is slidably connected in each set of guide rails, and the guide block is fixedly installed on one side of the corresponding drawer body.

[0009] By adopting the above technical solutions, the design of the guide rails and guide blocks can reduce the friction during the movement of the drawer body, thereby making the movement of the drawer body more stable and smooth.

[0010] The present invention is further configured such that a slot is provided on one side of the connecting block, and a card block that fits into the slot is slidably connected in the slot, and the card block and the slot are connected by a set of first springs.

[0011] By adopting the above technical solution, the design of the slot and the block increases the stability of the block's movement. Therefore, when the block is squeezed by the rotating shaft, it can move downwards. At the same time, the design of the first spring allows the block to move downwards under pressure, and after the pressure disappears, it can be reset by the first spring, so that this structure can be reused, thereby better opening and closing the main body of the drawer.

[0012] The present invention is further configured such that a plurality of support plates are installed inside the main body of the drawer, and the main body of the drawer and the support plates are connected by bolts.

[0013] By adopting the above technical solution and using bolts to install the support plate inside the main body of the drawer, the structural strength of the main body of the drawer can be increased through the support plate, thereby making it more stable.

[0014] The present invention is further configured such that adjacent groups of sliders are connected by connectors.

[0015] By adopting the above technical solution, multiple sets of sliders can be connected by connectors. When one set of sliders moves and compresses the second spring, the connectors can hold the other sliders in place, preventing the rest of the drawer body from moving and achieving an interlocking state.

[0016] The present invention is further configured such that the distance between the fixing block and the card block matches the size of the rotating shaft.

[0017] By adopting the above technical solution, the rotating shaft can be moved more effectively by using the fixing block and the locking block.

[0018] The present invention is further configured such that the side of the card block away from the fixed block is configured as an inclined surface structure.

[0019] By adopting the above technical solution, when the rotating shaft needs to enter between the fixed block and the locking block, the inclined structure of the locking block can make the rotating shaft squeeze better, thereby driving the rotating shaft to move better.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention pushes one of the drawer bodies inward, causing the bottom of the rotating shaft to contact the side of the locking block away from the fixed block and press the locking block downward until the bottom of the rotating shaft smoothly enters between the fixed block and the locking block. Then, by pushing the drawer body inward, the fixed block moves synchronously with the connecting block, pushing the rotating shaft. This allows the slider to slide in the dovetail groove through the linkage transmission, compressing the second spring. As a result, the other sliders are locked due to the structural linkage and cannot move, achieving interlocking with other drawer bodies and preventing them from opening. This avoids the instability and imbalance caused by multiple drawer bodies opening simultaneously, which could easily lead to the drawer body tipping over and causing danger. This also extends the service life of the drawer body and helps improve its stability and safety. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] The drawer interlocking structure of the chest of drawers, such as Figure 1-7 As shown, the device includes a chest of drawers body 1, with several drawer bodies 2 slidably connected to one end of the chest of drawers body 1. The drawer bodies 2 can be opened and closed by moving within the chest of drawers body 1. Several sets of guide rails 3 are installed on both sides of the chest of drawers body 1, which fit with the drawer bodies 2. Each set of guide rails 3 has a guide block 4 slidably connected within it, and the guide block 4 is fixedly installed on the corresponding side of the drawer body 2. The design of the guide rails 3 and guide blocks 4 can reduce the friction between the drawer body 2 and the chest of drawers body 1, thereby making the movement of the drawer bodies 2 more stable and smooth.

[0033] Subsequently, a dovetail groove 10 is fixedly connected to one side of the main body 1 of the drawer. Several sliders 11 that fit with the main body 2 of the drawer are slidably connected within the dovetail groove 10. The dovetail groove 10 can restrict the movement direction and range of the sliders 11. A connecting block 5 is fixedly connected to one side of each drawer body 2. An unlocking device 18 that fits with the connecting block 5 is installed on one side of the main body 1 of the drawer. A fixing block 6 is fixedly connected to one side of each connecting block 5. A locking block 8 is slidably connected to one side of each connecting block 5. Therefore, when the drawer body 2 moves, it can drive the connecting block 5 to move, so that the fixing block 6 and the locking block 8 can move synchronously with the connecting block 5. The connecting block 5 and the locking block 8 are connected by a set of first springs 9. Therefore, the locking block 8 can move when it is squeezed by the outside, and it will reset by the first spring 9 after the squeezing force is removed. A connecting rod 12 is rotatably connected to one side of each slider 11. One end of a set of connecting rods 12 is connected to the other end of a rotating shaft 13. Therefore, when the rotating shaft 13 presses the locking block 8 into the space between the fixed block 6 and the locking block 8, the movement of the drawer body 2 can synchronously drive the rotating shaft 13 to move. This, in turn, pushes the slider 11 to move within the dovetail groove 10 via the connecting rod 12. The top of the dovetail groove 10 is connected to the topmost slider 11 via a second spring 15. Therefore, when one of the drawer bodies 2 needs to be opened, the rotating shaft 13 can be driven to move, and the slider 11 can be pushed to slide via the connecting rod 12, thereby compressing the second spring 15. This prevents the remaining sliders 11 from having any room to move, thus achieving interlocking with the remaining drawer bodies 2. This avoids the instability and loss of balance caused by multiple drawer bodies 2 being opened at the same time, which could easily lead to the drawer body 1 tipping over and causing danger. This extends the service life of the drawer body 1 and helps improve its stability and safety.

[0034] A slot 7 is provided on one side of the connecting block 5, and a locking block 8 that slidably connects to the slot 7 is provided. The design of the slot 7 can increase the stability of the movement of the locking block 8, so that the locking block 8 can move better. At the same time, the locking block 8 and the slot 7 are connected by a set of first springs 9. Therefore, when the locking block 8 is squeezed and moves downward, and after the squeezing force is removed, the first spring 9 can drive the locking block 8 to reset, so that this structure can be used repeatedly, thereby realizing the repeated opening and closing of the drawer body 2.

[0035] Furthermore, several support plates 16 are installed inside the main body 1 of the drawer, and the main body 1 of the drawer and the support plates 16 are connected by bolts 17. The connection method of bolts 17 can quickly complete the installation of the support plates 16, and the support plates 16 can increase the structural strength of the main body 1 of the drawer, thereby making it more stable. At the same time, the side of the locking block 8 away from the fixing block 6 is set as an inclined structure. Therefore, when the rotating shaft 13 enters between the fixing block 6 and the locking block 8, the bottom of the rotating shaft 13 can better squeeze the locking block 8 through the inclined structure of the locking block 8.

[0036] In this embodiment, adjacent groups of sliders 11 are connected by connectors 14. The connectors 14 can increase the connectivity between groups of sliders 11. When one drawer body 2 is opened, it moves the corresponding group of sliders 11 and compresses the second spring 15. The connectors 14 can prevent other sliders 11 from moving, thus achieving interlocking of other drawer bodies 2. In addition, the distance between the fixing block 6 and the locking block 8 matches the size of the rotating shaft 13, so that the fixing block 6 and the locking block 8 can better drive the rotating shaft 13 to move.

[0037] Therefore, when all drawer bodies 2 inside the main body 1 of the chest of drawers are closed, the slider 11 remains in place because the drawer does not move the connecting block 5, ensuring that any drawer body 2 can be opened. When it is necessary to open one of the drawer bodies 2, the drawer body 2 can be gently pushed inward first, so that the bottom of the rotating shaft 13 contacts the side of the locking block 8 away from the fixed block 6 and squeezes the locking block 8, moving downward until the bottom of the rotating shaft 13 smoothly enters between the fixed block 6 and the locking block 8. Then, push the drawer body 2 inward, and the fixed block 6 moves synchronously with the connecting block 5, pushing the rotating shaft 13 to move. Then, the slider 11 can slide in the dovetail groove 10 through the transmission of the connecting rod 12, compressing the second spring 15. Therefore, the other sliders 11 are locked due to the structural linkage and cannot move, realizing the interlocking of other drawer bodies 2 and thus preventing them from being opened. This avoids multiple drawer bodies 2 being opened. Opening all drawer bodies 2 simultaneously can cause instability and loss of balance, potentially leading to the chest of drawers 1 tipping over and posing a danger. After use, the drawer body 2 can be pushed inward again, repeating the operation of the pivot 13 pressing the locking block 8. Once the pivot 13 re-enters between the fixing block 6 and the locking block 8, the drawer body 2 can be pulled outward slightly. At this time, the side of the locking block 8 closest to the fixing block 6 interacts with the pivot 13, driving the slider 11 to move through the pivot 13 and connecting rod 12 until the pivot 13 reaches its limit position. The locking block 8 can no longer drive the pivot 13 to move, and the bottom of the side of the pivot 13 away from the fixing block 6 presses the locking block 8, disengaging it from the limits of the fixing block 6 and the locking block 8. This allows the other drawer bodies 2 to be unlocked, and any one of the drawer bodies 2 in the entire chest of drawers 1 can be opened, facilitating better use of the chest of drawers 1.
