Description

Technical Field

[0001] This utility model relates to the field of furniture and storage equipment technology, and in particular to a drawer with a safety limiting structure. Background Technology

[0002] Drawers are pull-out components widely used in furniture, office equipment, and various storage devices. They are usually box-shaped with an opening, equipped with a panel to cover the front of the opening, and move back and forth by means of a sliding structure that adapts to the external carrier (such as a cabinet or table). They can be hidden inside the carrier when closed and expose the internal space when opened. They are common auxiliary storage structures in daily life and work scenarios.

[0003] The core function of drawers is to provide enclosed and easily accessible storage space, allowing for the centralized storage of loose items (such as clothing, stationery, tools, etc.), preventing items from being exposed and cluttered, while also protecting them from dust contamination. Their pull-out design allows users to quickly retrieve and place items without tilting the cabinet, making operation convenient. In addition, in the overall design of furniture, drawers can optimize the space layout, making full use of the internal depth of the cabinet, and improving the storage capacity and flexibility of the furniture.

[0004] However, in the existing technology, the limiting mechanism of some drawers sets the limiting components (such as bolts and blocks) directly on the inner wall of the top of the drawer, or the limiting components protrude from the inner wall of the drawer after installation. A single limiting mechanism can easily lead to deformation or damage of the limiting components. In addition, such a design will occupy the valuable storage space inside the drawer, making it impossible to store larger items smoothly and reducing the actual efficiency of the drawer. Therefore, a drawer with a safety limiting structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a drawer with a safety limiting structure, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A drawer with a safety limiting structure includes a cabinet body, at least one drawer body is slidably installed inside the cabinet body, a drawer front baffle is fixedly connected to the front end of the drawer body, a pull plate is fixedly connected to either the upper or lower end of the drawer front baffle, a limiting mechanism is provided between the drawer body and the cabinet body, and an anti-accidental contact mechanism is provided between the pull plate and the cabinet body. The limiting mechanism includes two pre-embedded holes on the left and right side walls of the drawer body. A threaded rod is threadedly installed on the inner wall of the pre-embedded hole. A limiting rod is fixedly connected to the side of the threaded rod away from the center of the drawer body. A limiting groove extending along the sliding direction of the drawer is opened on the inner wall of the left and right sides of the cabinet corresponding to the position of the limiting rod. A guide groove is opened on both the left and right sides of the drawer body. As a further description of the above technical solution: The outer wall of the limiting rod is slidably engaged with the inner wall of the limiting groove, and the limiting rod can slide along the length of the limiting groove to the end of the groove. As a further description of the above technical solution: The cross-section of the pre-embedded hole is T-shaped. The end of the threaded rod near the drawer body is provided with a limiting end cap that is adapted to the T-shaped pre-embedded hole. The outer diameter of the limiting end cap is larger than the opening diameter of the pre-embedded hole, and the end face of the limiting end cap is in contact with the stepped surface of the T-shaped pre-embedded hole. As a further description of the above technical solution: The left and right inner walls of the cabinet are fixedly connected with guide protrusions at the positions corresponding to the guide grooves of the drawer body, and the outer wall of the guide protrusions slides in conjunction with the inner wall of the guide groove. As a further description of the above technical solution: The anti-accidental touch mechanism includes a transmission rod that slides through the inside of the snap-on plate. The front end of the transmission rod extends out of the snap-on plate and is fixedly connected to a pull plate. A return spring is sleeved on the outside of the transmission rod. The rear end of the transmission rod extends into the inside of the snap-on plate and is fixedly connected to a transmission seat. Transmission plates are rotatably connected to both sides of the transmission seat via pins. A sliding rod is rotatably connected to the end of each of the two transmission plates away from the transmission seat via pins. As a further description of the above technical solution: The rear side of the pull plate contacts the front side of the snap-on pull plate, and the snap-on pull plate has a cavity inside; As a further description of the above technical solution: The outer wall of the transmission seat is slidably connected to the inner wall of the chamber. Both the front side of the transmission seat and the front inner wall of the chamber are fixedly connected to circular plates. The front and rear sides of the return spring are fixedly connected to the adjacent sides of the two circular plates. As a further description of the above technical solution: The two sliding rods slide through the inside of the pull plate in a direction perpendicular to the drawer's sliding direction, and the end of the sliding rod away from the transmission plate can engage with the left and right inner walls of the cabinet.

[0007] This utility model has the following beneficial effects: 1. In this utility model, pre-embedded holes are opened on both the left and right side walls of the drawer body, and threaded rods and limiting rods are installed thereon. The limiting rods on both sides slide and cooperate with the limiting grooves on the inner wall of the cabinet. When the drawer is pulled to its maximum stroke, the limiting rods on both sides are simultaneously blocked by the end of the grooves, forming a bidirectional limit, which has high safety performance. The side structure of the limiting mechanism does not occupy the internal space of the drawer, and no parts protrude from the inside of the drawer, ensuring the integrity of the storage space. Moreover, the hidden design is more beautiful and simple. There are no exposed parts on the outside of the limiting mechanism, which effectively solves the problems of traditional drawers being easy to fall off, sliding jamming, wasting space, and poor aesthetics.

[0008] 2. In this invention, in its natural state, the return spring inside the pull plate extends, pushing the transmission seat backward and causing the transmission plate to rotate, extending the sliding rod and engaging it with the cabinet body. This restricts the drawer's sliding and prevents children from accidentally pulling or touching it, thus opening the drawer. During normal use, the user simply pulls the pull plate forward, which in turn pulls the transmission seat via the transmission rod, compressing the return spring and causing the sliding rod to retract and release the engagement. This operation is convenient. Furthermore, the circular plate provides a stable fixing point for the return spring, preventing spring displacement and ensuring the long-term reliable operation of the anti-accidental contact mechanism, thus extending the overall lifespan of the drawer.

[0011] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a drawer with a safety limiting structure, comprising a cabinet body 1, with at least one drawer body 2 slidably installed inside the cabinet body 1. The cabinet body 1 is the basic support structure of the entire drawer device, and its interior provides installation and sliding space for the drawer body 2. A drawer front baffle 3 is fixedly connected to the front end of the drawer body 2. The drawer body 2 and the drawer front baffle 3 form a space for storing items. A pull plate 4 is fixedly connected to either the upper or lower end of the drawer front baffle 3. The pull plate 4 provides a force point for the user to easily pull the drawer body 2. A limiting mechanism is provided between the drawer body 2 and the cabinet body 1, and an anti-accidental contact mechanism is provided between the pull plate 4 and the cabinet body 1.

[0013] Reference Figure 1 , Figure 2 and Figure 3 The limiting mechanism includes two pre-embedded holes 5 on the left and right side walls of the drawer body 2. Threaded rods 6 are threaded onto the inner walls of the pre-embedded holes 5, facilitating installation and disassembly. A limiting rod 7 is fixedly connected to the side of the threaded rod 6 away from the center of the drawer body 2. Limiting grooves 8 extending along the drawer sliding direction are provided on the inner walls of the left and right side walls of the cabinet 1 corresponding to the positions of the limiting rods 7. The outer wall of the limiting rod 7 slides in cooperation with the inner wall of the limiting groove 8, and the limiting rod 7 can slide along the length of the limiting groove 8 to the end of the groove. When the drawer body 2 slides, the limiting rod 7 slides synchronously along the limiting groove 8. When the drawer is pulled to its maximum stroke, the limiting rod 7 slides to the end of the limiting groove 8 and is blocked by the end of the groove, thereby limiting the drawer body 2 from continuing to slide and preventing the drawer from falling off. Guide grooves are provided on both the left and right sides of the drawer body 2. Guide protrusions 9 are fixedly connected to the inner walls of the left and right sides of the cabinet body 1 at the positions corresponding to the guide grooves of the drawer body 2. The outer wall of the guide protrusions 9 slides with the inner wall of the guide groove. The main function of the guide protrusions 9 and the guide groove is to provide guidance for the sliding of the drawer body 2, prevent the drawer from shifting or shaking to the left or right during the process of pulling out or pushing in, and ensure smooth sliding. The length direction of the guide protrusions 9 is consistent with the limiting slide groove 8, and can work together with the limiting mechanism to enhance the stability of the drawer sliding. The cross-section of the pre-embedded hole 5 is T-shaped. The threaded rod 6 is provided with a limiting end cap that is compatible with the T-shaped pre-embedded hole 5 at one end near the drawer body 2. The outer diameter of the limiting end cap is larger than the opening diameter of the pre-embedded hole 5, and the end face of the limiting end cap fits with the stepped surface of the T-shaped pre-embedded hole 5. It does not occupy the internal space of the drawer, and this hidden design is more beautiful and simple.

[0014] Reference Figure 2 , Figure 4 and Figure 5 The anti-accidental touch mechanism includes a transmission rod 10 that slides through the pull plate 4. The front end of the transmission rod 10 extends out of the pull plate 4 and is fixedly connected to a pull plate 11. The rear side of the pull plate 11 contacts the front side of the pull plate 4. The pull plate 11 is the force-applying component for the user to operate the anti-accidental touch mechanism. A return spring 12 is sleeved on the outside of the transmission rod 10. The return spring 12 is the reset power source for the anti-accidental touch mechanism. The rear end of the transmission rod 10 extends into the pull plate 4 and is fixedly connected to a transmission seat 13. The left and right sides of the transmission seat 13 are connected by pins. A transmission plate 14 is rotatably connected to the shaft. The transmission seat 13 can move back and forth with the transmission rod 10, thereby driving the transmission plate 14 to rotate. The ends of the two transmission plates 14 away from the transmission seat 13 are rotatably connected to sliding rods 15 through pins. The two sliding rods 15 slide through the inside of the drawer plate 4 in a direction perpendicular to the sliding of the drawer. When the transmission seat 13 moves back and forth, the transmission plate 14 rotates around the pin, converting the back and forth linear motion of the transmission seat 13 into the left and right linear motion of the sliding rods 15, thereby realizing the extension and retraction of the sliding rods 15. The end of the sliding rod 15 away from the transmission plate 14 can engage with the inner walls of the left and right sides of the cabinet 1. In its natural state, the return spring 12 is in the extended state, pushing the transmission seat 13 to move backward, so that the sliding rod 15 extends and engages with the cabinet 1, restricting the sliding of the drawer and preventing accidental contact. When the user pulls the pull plate 11, the return spring 12 is compressed and stores the elastic force. After the pull plate 11 is released, the elastic force of the return spring 12 pushes the transmission seat 13 to reset, so that the anti-accidental contact mechanism returns to the locked state. The pull plate 4 has a cavity 17 inside. The cavity 17 is the installation and movement space for the components of the anti-accidental contact mechanism, ensuring that the components can move smoothly inside without mutual interference. The outer wall of the transmission seat 13 is slidably connected to the inner wall of the cavity 17. The front side of the transmission seat 13 and the front inner wall of the cavity 17 are both fixedly connected to circular plates 16. The front and rear sides of the return spring 12 are fixedly connected to the adjacent side of the two circular plates 16. The circular plates 16 are used to provide a stable fixing point for the return spring 12, ensuring that the return spring 12 is in the direction of the axis of the transmission rod 10, and preventing the return spring 12 from shifting during the extension and retraction process.

[0015] Working principle: Threaded rods 6 are installed in the pre-embedded holes 5 on the left and right side walls of the drawer body 2. A limiting rod 7 fixed to the outside of the threaded rod 6 slides in conjunction with a corresponding limiting groove 8 on the inner wall of the cabinet body 1. Simultaneously, the grooves on the left and right sides of the drawer body 2 slide in conjunction with the guide plates 9 on the inner wall of the cabinet body 1, providing stable guidance for the drawer's movement. When the user pulls the drawer body 2 using the pull plate 4, the drawer body 2 slides outward along the direction of the guide plate 9 and the groove. At this time, the limiting rod 7 slides synchronously along the length of the limiting groove 8. When the drawer body 2 is pulled to its maximum stroke, the limiting rod 7 slides to the end of the limiting groove 8. The end structure of the limiting groove 8 blocks the limiting rod 7, restricting it from sliding further outward. This, in turn, through the fixed relationship between the threaded rod 6 and the pre-embedded holes 5, stops the drawer body 2 from moving, effectively preventing the drawer body 2 from falling out of the cabinet body 1. In its natural state, the return spring 12 sleeved on the outside of the transmission rod 10 is in an extended state. The two ends of the return spring 12 are respectively connected to the inner wall of the front side of the chamber 17 and the circular plate 16 on the front side of the transmission seat 13. The spring force pushes the transmission seat 13 to move backward in the chamber 17. When the transmission seat 13 moves, the transmission plates 14 connected to its left and right sides by pins rotate accordingly. The end of the transmission plate 14 away from the transmission seat 13 drives the sliding rod 15 to extend outward in a direction perpendicular to the sliding of the drawer, so that the end of the sliding rod 15 away from the transmission plate 14 engages with the inner walls of the left and right sides of the cabinet 1. At this time, the drawer body 2 is restricted from sliding, achieving the effect of preventing accidental contact. When the user needs to pull the drawer normally, the pull plate 11 needs to be pulled forward. The pull plate 11 drives the transmission rod 10 to slide forward. The transmission rod 10 pulls the transmission seat 13 to compress the return spring 12. The movement of the transmission seat 13 causes the transmission plate 14 to rotate in the opposite direction, which in turn pulls the sliding rod 15 back into the pull plate 4, releasing the engagement with the cabinet body 1. At this time, the user can pull the pull plate 4 to drive the drawer body 2 to slide normally.
