Description

Technical Field

[0001] This utility model belongs to the field of furniture parts technology, specifically a flat self-locking handle for drawers. Background Technology

[0002] Furniture drawers are a common storage design, widely used in various furniture pieces such as wardrobes, desks, and kitchen cabinets. Drawers connect to the frame via a sliding rail system, facilitating opening, closing, and accessing items. Typically, steel or plastic handles are installed to enable drawer opening and closing. Existing handle structures are relatively simple, lack any covering, making them prone to dust accumulation. The feel of pulling out and opening / closing is not ideal, and their design is limited. Alternatively, ordinary flip-top handles are used, but these have a large gap between the pivot points, exposing the structure and affecting aesthetics. Furthermore, common drawer handles lack a self-locking function, allowing drawers to be easily pulled out and accidentally opened by strangers or children, potentially exposing children to dangerous items inside and posing a significant safety hazard. Therefore, researching a new flat-panel self-locking drawer handle to solve these problems is of great significance. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a flat self-locking handle for drawers, which solves the problems of existing handle structures being too simple, affecting aesthetics, and common drawer handles not being able to achieve a self-locking function, making the drawer easy to be pulled out and easily opened by strangers or children, thus allowing children to come into contact with dangerous items inside the drawer, posing a significant safety hazard.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flat self-locking handle for a drawer, comprising a handle frame, a flip cover inside the handle frame, a flip structure connected to one side of the flip cover, the bottom of the flip structure connected to the bottom wall of the handle frame, two housings fixedly connected to one side of the handle frame, the bottom of the housings communicating with an air bladder through a pipe, the air bladder being mounted on the housings, a piston inside the housings, a spring fixedly connected above the piston, the top of the spring fixedly connected to the top wall of the housings, a movable strip fixedly connected above the piston, the movable strip passing through the housings and fixedly connected to an adjusting latch, the adjusting latch limiting the handle frame through a limiting structure.

[0007] As a further embodiment of this utility model: the flip structure includes two fixing blocks and a fixing member. The bottom of the fixing member is fixedly connected to the bottom wall of the handle frame. The two fixing blocks are fixedly connected to the flip cover, and the two fixing blocks are hinged to the fixing member through pins.

[0008] As a further embodiment of this utility model: torsion springs are fixedly connected to the opposite surfaces of the two fixing blocks, and one end of each torsion spring is fixedly connected to both sides of the fixing member.

[0009] As a further embodiment of this utility model: the bottom wall of the handle frame and the two sides of the fixing member are respectively fixedly connected with a baffle and a baffle plate, and the baffle overlaps with the flip cover.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This flat self-locking handle for drawers uses a flip-up mechanism to automatically flip the lid and keep it upright, embedding the lid into the handle frame to form a flat structure. This creates a concealed handle structure, ensuring overall aesthetics and preventing dust accumulation. Secondly, when the drawer is pushed into the outer shell, the inclined surface of the adjusting latch presses against the inclined surface of the fixed latch, allowing the adjusting latch to move upwards smoothly past the fixed latch. Then, a spring drives the piston downwards to reset, locking the adjusting latch and the fixed latch together, achieving the self-locking purpose of the drawer. Furthermore, opening the drawer requires not only pushing open the lid but also pressing the air spring, thus preventing accidental opening by children.

[0016] 2. This flat self-locking handle for drawers can cover the flip structure with a baffle, thus providing protection. The baffle can also limit the flip cover to prevent it from flipping outwards when it resets. This keeps the flip cover and the handle frame on the same plane, maintaining neatness and aesthetics.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1-7As shown, this utility model provides a technical solution: a flat self-locking handle for a drawer, including a handle frame 1, a flip cover 3 inside the handle frame 1, a flip structure 6 connected to one side of the flip cover 3, the flip structure 6 including two fixing blocks 61 and a fixing member 63, the bottom of the fixing member 63 being fixedly connected to the bottom wall of the handle frame 1, the two fixing blocks 61 being fixedly connected to the flip cover 3, and the two fixing blocks 61 being hinged to the fixing member 63 by pins, the fixing blocks 61 being movable by the pins, thereby allowing the flip cover 3 to be flipped smoothly, and torsion springs 62 being fixedly connected to the opposite surfaces of the two fixing blocks 61, the torsion springs 62... The flip cover 3 is rotated and stood upright, keeping the flip cover 3 and the handle frame 1 on the same plane, thus achieving the purpose of hiding the handle. One end of each of the two torsion springs 62 is fixedly connected to the two sides of the fixing member 63. The bottom of the flip structure 6 is connected to the bottom wall of the handle frame 1. The bottom wall of the handle frame 1 and the two sides of the fixing member 63 are fixedly connected to the baffle strip 7 and the baffle plate 4 respectively. The baffle plate 4 can cover the flip structure 6, thus playing a protective role. The baffle strip 7 can limit the flip cover 3 to prevent the flip cover 3 from resetting and causing it to flip outward. This keeps the flip cover 3 and the handle frame 1 on the same plane, maintaining neatness and aesthetics. The baffle strip 7 overlaps with the flip cover 3.

[0027] The handle frame 1 is embedded in the drawer 13, which is slidably mounted in the outer casing 14. Two housings 8 are fixedly connected to one side of the handle frame 1. The lower part of the housings 8 is connected to the airbag 5 through a pipe. By flipping the flap 3 inward and pressing the airbag 5, gas enters the housings 8, and the air pressure controls the piston 9 to move upward, causing the movable strip 11 to drive the adjusting latch 12 upward and disengage it from the fixed latch 22. At this time, the handle frame 1 can be pulled directly to pull out the drawer 13. The airbag 5 is mounted on the housing 8, and the piston 9 is installed inside the housing 8. The upper part of the piston 9 is fixedly connected to... A spring 10 is provided. When the drawer 13 is pushed back to the outer shell 14, and the adjusting latch 12 passes through the fixed latch 22, the spring 10 drives the piston 9 to reset, causing the movable bar 11 to engage the adjusting latch 12 with the fixed latch 22, thus achieving the self-locking purpose of the drawer 13. The top of the spring 10 is fixedly connected to the top wall of the shell 8, and the movable bar 11 is fixedly connected above the piston 9. The movable bar 11 passes through the shell 8 and is fixedly connected to the adjusting latch 12. The adjusting latch 12 limits the handle frame 1 through the limiting structure 2. The limiting structure 2 includes a mounting part 21. The mounting component 21 is bolted to the top wall of the outer casing 14. Two fixing latches 22 are fixedly connected to the lower part of the mounting component 21. These two fixing latches 22 engage with the adjusting latch 12. The fixing latches 22 are L-shaped, and the distance between the horizontal ends of the two fixing latches 22 is greater than the width of the movable strip 11. By designing the width of the movable strip 11 to be smaller than the distance between the horizontal ends of the two fixing latches 22, the movable strip 11 can pass through smoothly. Furthermore, the distance between the vertical ends of the fixing latches 22 is greater than the length of the adjusting latch 12, allowing the adjusting latch 12 to pass through smoothly. This ensures the smooth passage of the drawer 1. The drawer 13 opens smoothly, and the fixed latch 22 and the adjusting latch 12 are designed with a bevel. When the drawer 13 is pushed back into the housing 8, the bevel of the adjusting latch 12 can press against the bevel of the fixed latch 22, causing the adjusting latch 12 to move upward, thus facilitating the smooth passage of the adjusting latch 12 without separate operation. In addition, the adjusting latch 12 can be automatically locked with the spring 10, which facilitates the automatic self-locking of the drawer 13. The distance between the vertical ends of the two fixed latches 22 is greater than the length of the adjusting latch 12, and the lower side of the fixed latch 22 and the upper side of the adjusting latch 12 are designed with bevels.

[0028] The working principle of this utility model is as follows: When opening the drawer 13, first push the top of the flip cover 3 so that the flip cover 3 flips inward into the drawer 13. Then, press the air bag 5 with your hand so that the gas inside the air bag 5 enters the housing 8, causing the air pressure control piston 9 to move upward. The piston 9 drives the movable bar 11 to move upward, and the movable bar 11 drives the adjusting latch 12 to move upward, so that the adjusting latch 12 is disengaged from the fixed latch 22. At this time, the handle frame 1 can be pulled directly to pull out the drawer 13.

[0029] After drawer 13 is used, push the handle frame 1 to move drawer 13 into outer shell 14. When the inclined surface of adjusting latch 12 is pressed against the inclined surface of fixed latch 22, adjusting latch 12 moves upward, causing moving bar 11 to move piston 9 upward. Piston 9 causes spring 10 to deform. When adjusting latch 12 is disengaged from fixed latch 22 and passes through fixed latch 22, spring 10 causes piston 9 to return to its original position, so that adjusting latch 12 locks with fixed latch 22 again, realizing self-locking of drawer 13.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
