Single opening and closing self-adapting drawer cabinet based on wire harness limiting

Abstract

This invention relates to the field of daily furniture technology, specifically to a single-opening adaptive drawer cabinet based on wire harness limiting. The cabinet includes a cabinet body, with multiple drawer bodies connected to the inner wall of the cabinet via slide rails. Each drawer body has a pull ring at one end, and a wire harness is inserted inside the pull ring to open and close a single drawer body. Both ends of the wire harness are connected to a pull-back assembly for automatic tensioning and straightening. A locking assembly is located at the bottom of the cabinet to improve its stability. This invention, through the pull-back assembly and wire harness, ensures that only one drawer body can be opened at a time. If another drawer body is forcibly opened, the already opened drawer body will automatically close, preventing the cabinet from tipping over when multiple drawer bodies are open. Furthermore, when a single drawer body is fully opened, a suction cup generates a certain negative pressure suction, further improving the stability of the cabinet when placed.

Description

Technical Field

[0001] This invention relates to the field of daily furniture technology, specifically to a single-opening adaptive drawer cabinet based on wire harness limiting. Background Technology

[0002] As a common type of storage furniture, chests of drawers are widely used in homes, offices, and other settings. To meet the demand for large-capacity storage, most chests of drawers adopt a multi-drawer side-by-side or stacked structure. However, this means that if users pull out multiple drawers at the same time, the center of gravity of the chest of drawers will shift forward quickly, which can easily lead to the risk of tipping over and pose a safety hazard. This problem is particularly prominent for tall chests of drawers and multi-layered wooden chests of drawers.

[0003] Existing multi-drawer anti-tipping structures mostly employ rigid linkage interlocking, independent limit blocks, or wall-mounted fixing straps. Among these, rigid linkage mechanisms are complex in structure, require high assembly precision, and are costly. Independent limit blocks can only restrict the pull-out stroke of a single drawer and cannot achieve interlocking constraints between drawers, leaving the possibility of multiple drawers being pulled out simultaneously. While wall-mounted fixing straps can prevent the cabinet from tipping over, they compromise the flexibility of cabinet placement, are inconvenient to install and disassemble, and affect adaptability to various usage scenarios.

[0004] Therefore, it is necessary to invent a single-opening adaptive drawer cabinet based on wire harness limiting to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a single-opening adaptive drawer cabinet based on wire harness limiting. Through the mechanical limiting design after the wire harness is tightened, it can be realized that only one drawer can be opened at a time, so as to avoid the cabinet tipping over due to multiple drawers being opened at the same time.

[0006] To achieve this objective, the present invention adopts the following technical solution: A single-opening adaptive drawer cabinet based on wire harness limiting is provided, including a cabinet body. Multiple drawer bodies are connected to the inner wall of the cabinet body via slide rails. Each drawer body has a pull ring at one end, and a wire harness for opening and closing a single drawer body is inserted inside the pull rings. Both ends of the wire harness are connected to a pull-back assembly for automatically tightening and straightening the wire harness. The pull-back assembly includes sliding plates slidably connected to the top and bottom of the cabinet body, respectively. One end of each sliding plate is fixedly connected to both ends of the wire harness. A limiting block is fixedly connected to the inner wall of the cabinet to restrict excessive sliding of the sliding plate. A locking assembly is provided at the bottom of the cabinet body to improve cabinet stability. When the sliding plate abuts against the limiting block, the sliding plate triggers the locking assembly and adheres to the ground for locking.

[0007] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, the pull-back assembly further includes a slide rod fixedly connected to the inner wall of the cabinet. The slide plate is sleeved on the outside of the slide rod and slides along the axial direction of the slide rod. A long spring is sleeved on the surface of the slide rod and fixedly connected to the inner wall of the cabinet and one side of the slide plate. The long spring is used to automatically tighten and gather the wire harness after the drawer body is closed.

[0008] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, a guide wheel is rotatably connected to the inner wall of the cabinet on one side of the limiting block. The guide wheel is used to guide the direction of the wire harness rope.

[0009] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, a rubber pad is fixedly connected to one side of the slide, and the rubber pad corresponds one-to-one with the limiting block.

[0010] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, a limiting ring is sleeved on the surface of the wire harness rope, one end of which is fixedly connected to the inner wall of the cabinet, and the limiting ring is used to guide the sliding of the wire harness rope.

[0011] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, the locking component includes suction cups symmetrically arranged at the bottom of the cabinet body. A fixing groove communicating with the suction cups and the interior of the cabinet body is provided at the bottom of the cabinet body. A piston block is slidably connected inside the fixing groove. A movable rod extending to the outside of the fixing groove is fixedly connected to the top of the piston block. A return spring is sleeved on the surface of the movable rod and fixedly connected to the top of the piston block and the top wall of the fixing groove. A connecting plate is fixedly connected to the top of the movable rod. A fixing block is fixedly connected to the bottom of the connecting plate. Drive rods are fixedly connected to both ends of the sliding plate.

[0012] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, the fixing block has a semi-circular structure and is at the same horizontal height as the drive rod; when the slide plate slides to the maximum travel position, the top end of the drive rod abuts against the bottom end of the fixing block.

[0013] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, one end of the pull ring is provided with an anti-pull damage component to prevent damage to the wire harness caused by violent pulling. The anti-pull damage component includes a fixed cylinder fixedly connected to one end of the drawer body, a sliding rod extending into the fixed cylinder fixedly connected to one end of the pull ring, a sliding block fixedly connected to one end of the sliding rod, and a fixing spring fixedly connected to the inner wall of the fixed cylinder and one end of the sliding block on the surface of the sliding rod.

[0014] As a preferred embodiment of a single-opening adaptive drawer cabinet based on wire harness limiting, the inner wall of the fixed cylinder is provided with a sliding groove, and the outer side of the sliding block is fixedly connected with a slider that slides and engages with the inside of the sliding groove.

[0015] The beneficial effects of this invention are as follows: 1. By using the pull-back component and the wire harness, once one drawer is fully opened, the wire harness is fully tightened and taut, which mechanically limits the other drawers, preventing them from being pulled open again. This ensures that only one drawer can be opened at a time, effectively preventing the cabinet's center of gravity from shifting or becoming unstable due to multiple drawers opening simultaneously, and eliminating safety hazards such as the cabinet tilting forward or tipping over. At the same time, the elastic force of the long spring, combined with the linkage of the limiting ring and the pull ring, keeps the wire harness slightly taut even after the drawer is fully closed, effectively preventing the wire harness from becoming loose, drooping, or tangled due to excessive length. This avoids the wire harness getting stuck on the guide rail and affecting the normal operation of the drawer, ensuring the long-term stable operation of the mechanism.

[0016] Once any drawer is fully extended, the piston block will rise simultaneously, creating negative pressure inside the suction cup and generating suction force. Since the suction cup is located at a key stress point at the bottom of the cabinet's back, when the drawer is opened and the cabinet's center of gravity tilts forward, the negative pressure of the suction cup can effectively counteract the forward tilting torque, thereby suppressing the cabinet's shifting and tipping tendency and significantly improving the overall anti-tipping stability of the cabinet. At the same time, when the drawer is closed and reset, the negative pressure of the suction cup is automatically released and the suction becomes ineffective, making it convenient for daily moving and repositioning of the cabinet, floor cleaning, and relocation, thus balancing stability and flexibility.

[0017] When a single drawer is in the open-locked state, if other drawers are forcibly pulled, the taut cable will exert a reverse pull constraint on the mistakenly opened drawer, forming an interlocking balance. This forces the opened drawer to gradually return to its original position and close, further strengthening the restriction effect of single opening. At the same time, when instantaneous impact loads are generated due to human forceful pulling or drawer sliding overtravel, the anti-pull damage component can absorb the instantaneous impact force, dissipate rigid tensile stress, and prevent the pulling force from being directly concentrated on the cable, causing wear, deformation, or breakage. This effectively extends the service life of the cable and the overall self-locking mechanism.

[0018] All components of this device are integrated inside the cabinet and at the bottom, adopting a hidden, integrated design with no exposed parts. This does not damage the overall appearance of the cabinet, making it cleaner, simpler, more concealed, and more aesthetically pleasing. At the same time, it avoids dust accumulation or damage to external structures, thus improving its practicality. Attached Figure Description

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0031] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0033] refer to Figures 1 to 8 This invention provides a single-opening adaptive drawer cabinet based on wire harness limiting, comprising a cabinet body 2, with multiple drawer bodies 1 connected to the inner wall of the cabinet body 2 via slide rails. Each drawer body 1 has a pull ring 8 at one end, and a wire harness 6 for opening and closing a single drawer body 1 is inserted inside the pull ring 8. Both ends of the wire harness 6 are connected to a pull-back assembly 3 for automatically tightening and straightening the wire harness 6. The pull-back assembly 3 includes a slide plate 35 slidably connected to the top and bottom ends of the cabinet body 2, with one end of the slide plate 35 fixedly connected to both ends of the wire harness 6. A limiting block 31 is fixedly connected to the inner wall of the cabinet body 2 to limit the excessive sliding of the slide plate 35. A locking assembly 7 is provided at the bottom of the cabinet body 2 to improve the stability of the cabinet body 2. When the slide plate 35 abuts against the limiting block 31, the slide plate 35 can trigger the locking assembly 7 and adhere to the ground for locking.

[0034] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the pull-back assembly 3 also includes a slide rod 33 fixedly connected to the inner wall of the cabinet 2. A slide plate 35 is sleeved on the outside of the slide rod 33 and slides axially along the slide rod 33. A long spring 34 is sleeved on the surface of the slide rod 33 and fixedly connected to the inner wall of the cabinet 2 and one side of the slide plate 35. The long spring 34 is used to automatically tighten the cord 6 after the drawer body 1 is closed. In this example, the elastic force of the long spring 34 is set to a small value, which is only used to pull the remaining amount of the straight cord 6 after the drawer body 1 is closed. Therefore, when the drawer body 1 is slid open, the sliding friction between the slide rails combined with the weight of the drawer body 1 itself forms a large resistance. The weak elastic force of the long spring 34 alone cannot overcome this resistance, so the drawer body 1 in the open state will not be automatically pulled back and closed.

[0035] In this embodiment, when the drawer body 1 is pulled out and opened, the pull ring 8 pulls the wire harness 6, which in turn causes the slide plate 35 to slide on the surface of the slide rod 33 and compress the long spring 34. The limit block 31 limits the maximum sliding distance of the slide plate 35. At this time, the drawer body 1 is fully opened, and because the wire harness 6 is fully tightened, when other drawer bodies 1 are pulled out and opened, they will be limited by the fully tightened wire harness 6 and cannot be opened. If other drawer bodies 1 are forcibly pulled out, the pulled wire harness 6 will also drive the already opened drawer body 1 to slide in the opposite direction and close. Thus, only one drawer body 1 can be opened at a time, avoiding the cabinet 2 from tipping over when multiple drawer bodies 1 are opened. At the same time, under normal use, after all the drawer bodies 1 are closed, the elasticity of the long spring 34 causes the slide plate 35 to slide back to its original position and tighten the retracted wire harness 6 again, preventing the retracted wire harness 6 from drooping, tangling, or even jamming the guide rail due to its long slack.

[0036] Specifically, such as Figure 4 and Figure 5 As shown, a guide wheel 32 is rotatably connected to the inner wall of the cabinet 2 on one side of the limiting block 31. The guide wheel 32 is used to guide the direction of the wire harness rope 6.

[0037] In this embodiment, by setting a rotating guide wheel 32, the wire harness rope 6 can be rotated and guided from the horizontal to the vertical direction, making the wire harness distribution more neat and preventing the wire harness rope 6 from drooping, tangling, or even getting stuck on the guide rail.

[0038] Specifically, such as Figure 5 and Figure 7 As shown, a rubber pad 351 is fixedly connected to one side of the slide plate 35, and the rubber pad 351 corresponds one-to-one with the limiting block 31.

[0039] In this embodiment, the rubber pad 351 can be used to achieve flexible buffering when the slide plate 35 contacts the limiting block 31, avoiding noise caused by hard collision. When the drawer body 1 is pulled out too forcefully, the deformation of the rubber pad 351 can also absorb a certain amount of collision energy, reducing the possibility of damage to the wire harness rope 6 caused by pulling.

[0040] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a limiting ring 5 is fitted on the surface of the wire harness 6. One end of the limiting ring 5 is fixedly connected to the inner wall of the cabinet 2. The limiting ring 5 is used to guide the sliding of the wire harness 6.

[0041] In this embodiment, the limiting ring 5 is used to ensure that the wire harness can be vertically and neatly distributed on the back side inside the drawer body 1. Example

[0042] In the above embodiment 1, a preferred embodiment of the single-opening adaptive drawer cabinet based on wire harness limiting provided by the present invention is, for example... Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the locking assembly 7 includes suction cups 71 symmetrically arranged at the bottom of the cabinet 2. A fixing groove 78 communicating with the suction cups 71 and the interior of the cabinet 2 is provided at the bottom of the cabinet 2. A piston block 76 is slidably connected inside the fixing groove 78. A movable rod 77 extending to the outside of the fixing groove 78 is fixedly connected to the top of the piston block 76. A return spring 75 is sleeved on the surface of the movable rod 77 and fixedly connected to the top of the piston block 76 and the inner top wall of the fixing groove 78. A connecting plate 74 is fixedly connected to the top of the movable rod 77. A fixing block 72 is fixedly connected to the bottom of the connecting plate 74. Drive rods 73 are fixedly connected to both ends of the sliding plate 35.

[0043] Specifically, such as Figure 5 and Figure 7 As shown, the fixed block 72 has a semi-circular structure and is at the same horizontal height as the drive rod 73; when the slide plate 35 slides to the maximum stroke position, the top of the drive rod 73 abuts against the bottom of the fixed block 72.

[0044] In this embodiment, it should be noted that the cabinet 2 is mostly used in home and office settings, where the floor is usually smooth, such as tile or wood flooring. Also, the suction cup 71 is slightly taller than the support legs at the bottom of the cabinet 2. Therefore, after the cabinet 2 is placed, the bottom of the suction cup 71 will be firmly attached to the ground. Then, during the opening and closing of the drawer body 1, the sliding plate 35 below will simultaneously drive the drive rod 73 to slide. When the drawer body 1 is fully opened, the drive rod 73 will move to the fixing block 72. The cooperation between the cylindrical drive rod 73 and the semi-circular fixing block 72 causes the fixing block 72 to rise, driving the connecting... When plate 74 rises, the movable rod 77 slides up inside the fixed groove 78, compressing the return spring 75. This allows some air inside the suction cup 71 to be drawn into the fixed groove 78, creating a negative pressure suction at the suction cup 71. This further improves the stability of the cabinet 2 after the drawer body 1 is opened. When the drawer body 1 is closed, the drive rod 73 separates from the fixed block 72. At this time, the elasticity of the return spring 75 causes the movable rod 77 to descend, driving the piston block 76 to descend and return to its original position. This allows the air pressure inside the suction cup 71 to return to its previous state, eliminating the negative pressure suction and reducing the inconvenience of moving the cabinet 2 later. Example

[0045] In the above embodiment 1, after the drawer body 1 is fully opened, if the user forcibly opens other drawer bodies 1 or pulls the drawer body 1 too far open due to improper operation, it will cause a large pulling force on the wire harness rope 6, which may lead to damage and breakage of the wire harness rope 6 in severe cases. In order to solve this problem, this embodiment provides an anti-pull damage component 4 that can elastically buffer and protect the wire harness rope 6.

[0046] Specifically, such as Figure 1 , Figure 3 , Figure 6 and Figure 8 As shown, one end of the pull ring 8 is provided with an anti-pull damage component 4 to prevent damage to the wire harness 6 caused by violent pulling. The anti-pull damage component 4 includes a fixed cylinder 41 fixedly connected to one end of the drawer body 1, a sliding rod 43 extending into the fixed cylinder 41 fixedly connected to one end of the pull ring 8, a sliding block 42 fixedly connected to one end of the sliding rod 43, and a fixed spring 44 fixedly connected to the inner wall of the fixed cylinder 41 and one end of the sliding block 42 on the surface of the sliding rod 43.

[0047] In this embodiment, when the drawer body 1 is violently pulled after the wire harness 6 is tightened, the fixing cylinder 41 will slide relative to the pull ring 8, causing the sliding rod 43 to drive the sliding block 42 to slide and compress the fixing spring 44 inside the fixing cylinder 41. In this way, the elastic force of the fixing spring 44 can absorb the force of violently pulling the drawer body 1, achieving its elastic buffering and avoiding direct action on the wire harness 6 to cause damage or breakage.

[0048] Specifically, such as Figure 8 As shown, the inner wall of the fixed cylinder 41 is provided with a groove 411, and the outer side of the sliding block 42 is fixedly connected with a slider 421 that slides in cooperation with the inside of the groove 411.

[0049] In this embodiment, the sliding of slider 421 inside the groove 411 makes the sliding block 42 slide more smoothly, so that the sliding block 42 can only slide horizontally, avoiding the sliding block 42 rotating slightly inside the fixed cylinder 41, which would cause the angle of the pull ring 8 to change and cause the normal sliding of the wire harness rope 6 to become stuck.

[0050] When using this invention, the cabinet 2 is placed in a suitable position. Then, during the process of pulling open the drawer body 1, the wire harness 6 is tightened and drives the sliding plate 35 to slide. At this time, the limit block 31 limits the maximum sliding distance of the sliding plate 35 to prevent the drawer body 1 from sliding open too much. At the same time, because the wire harness 6 is fully tightened at this time, it forms a mechanical limit, which forces other drawer bodies 1 to be constrained and cannot be pulled open again. When the drawer body 1 is closed, the sliding plate 35 returns to its original position, so that the wire harness 6 has enough room to move, allowing other drawer bodies 1 to be opened normally. Thus, only one drawer body 1 can be opened at a time, avoiding the cabinet 2 from being unstable and tipping over due to multiple drawer bodies 1 being opened. Meanwhile, after the drawer body 1 is fully pulled out, the locking component 7 can generate a certain negative pressure suction to make the cabinet body 2 more stable, further reducing the possibility of the cabinet body 2 tipping over. In addition, the anti-pull damage component 4 can protect the wire harness 6 from being pulled, preventing damage or breakage of the wire harness 6 due to improper operation or forceful opening of other drawer bodies 1.

[0051] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
