[0033] The utility model provides a drawer mechanism 100 .

[0034] Reference Figures 1 to 5 The embodiment of the drawer mechanism 100 includes a drawer body 2, a cabinet 1 and a sliding assembly 3. A partition 112 is provided in the cabinet 1. The partition 112 divides the cavity of the cabinet 1 into a plurality of accommodating cavities for accommodating the drawer body 2. The sliding assembly 3 includes a guide rail 31 and a slide rail 32. The guide rail 31 is fixedly arranged on the top surface of the partition 112, and the slide rail 32 is fixedly arranged on the bottom surface of the drawer body 2, and the slide rail 32 is slidably installed on the guide rail 31.

[0035] Most traditional drawer mechanisms use side-mounted slide rails, which occupy the lateral space of the drawer body, not only resulting in limited lateral dimensions of the drawer body 2, but also the slide rail structure can be seen from the side when the drawer is pulled out, which is not aesthetically pleasing. In the drawer mechanism 100 of the utility model, the cabinet 1 includes a frame assembly 11 and a shell 12, and the frame assembly 11 includes a top plate, a bottom plate, a side plate 111, and a plurality of partitions 112 arranged between the side plates 111, then a receiving cavity for storing the drawer body 2 is formed between the side plates 111, the top plate and the partitions 112, and between the side plates 111, the bottom plate and the partitions 112, or between the side plates 111 and two upper and lower adjacent partitions 112. Figure 3The figure shows an exploded view of the cabinet and the sliding assembly in an embodiment of the drawer mechanism 100, and in order to facilitate the observation of the sliding assembly 3, the sliding assembly 3 is exploded to the outside of the cabinet 1. Unlike the traditional drawer mechanism 100, the drawer mechanism 100 installs the guide rail 31 on the top surface of the partition 112, installs the slide rail 32 on the bottom surface of the drawer body 2, and then docks the slide rail 32 with the guide rail 31 to achieve the inside and outside sliding of the drawer body 2. It should be noted that the bottom of the cabinet 1 can be provided with a partition 112 and a bottom plate stacked arrangement. When the bottom of the cabinet 1 is not provided with a partition 112, the bottom plate acts as a partition, and at this time, the guide rail 31 is installed on the top surface of the bottom plate. Obviously, the sliding assembly 3 in the drawer mechanism 100 is a bottom-mounted design, which avoids the occupation of the horizontal space of the accommodating cavity by the sliding assembly 3, thereby increasing the width of the drawer body 2. At the same time, when the drawer body 2 slides out, the slide rail 32 cannot be seen from the side, thereby improving the aesthetics of the drawer body 2. At the same time, in order to ensure the sliding stability of the drawer body 2, two guide rails 31 and two slide rails 32 are usually provided, the two guide rails 31 are relatively arranged on both sides of the partition 112, the two slide rails 32 are relatively arranged on the bottom surface of the drawer body 2, and each slide rail 32 is slidably connected to a guide rail 31. Specifically, the guide rail 31 is L-shaped, including a side-mounted strip and a bottom-mounted strip arranged perpendicular to the side-mounted strip, wherein the side-mounted strip is fixedly connected to the side wall of the accommodating cavity, the bottom-mounted strip is fixedly connected to the top surface of the partition 112, and the slide rail 32 is slidably connected to the bottom-mounted strip.

[0036] In one embodiment of the present invention, the drawer body 2 and the slide rail 32 are detachably connected.

[0037] For example, refer to Figure 4 , Fig. 9 and Fig.10 A clamping member 5 is installed at the bottom of the drawer body 2. The clamping members 5 are relatively arranged on both sides of the drawer body 2. The drawer body 2 is clamped and fixed with the slide rail 32 through the clamping member 5.

[0038] Specifically, the clamping member 5 includes a transfer member 51 and a claw 52. The transfer member 51 is fixedly mounted at the bottom of the drawer body 2. The claw 52 is mounted on the transfer member 51 and is rotatably connected to the transfer member 51. A plug-in member 511 is convexly provided on one side of the transfer member 51 facing the slide rail 32. The slide rail 32 is hollow, and a clamping interface 324 is provided on the side wall of the slide rail 32. The plug-in member 511 is inserted into the hollow channel of the slide rail 32, and the claw 52 is inserted into the clamping interface 324 to realize the clamping fixation of the clamping member 5 and the slide rail 32, thereby facilitating the rapid assembly and disassembly of the drawer body 2 and the slide rail 32.

[0039] A torsion spring is provided between the claw 52 and the adapter 51 , one end of the torsion spring is connected to the adapter 51 , and the other end of the torsion spring is connected to the claw 52 . The torsion spring is used to provide torque to the claw 52 so that the claw 52 clamps the slide rail 32 .

[0040] Reference Figure 4 Two oppositely arranged brackets 21 are provided at the bottom of the drawer body 2. The brackets 21 are extended along the movement direction of the drawer body 2. The adapter 51 is fixedly connected to the brackets 21 by fasteners, thereby realizing the fixed connection between the clamping member 5 and the drawer body 2.

[0041] In this embodiment, the bracket 21 and the drawer body 2 are both sheet metal parts, and the two are fixed by welding. The cross section of the bracket is U-shaped, and the clamping member 5 and the bracket 12 are fixed by screws. Specifically, the adapter 51 and the bracket 12 are each provided with three corresponding threaded holes or through holes, and the screws pass through the adapter 51 and the bracket 12 to fix the clamping member 5 and the bracket 12 together. Since the bracket is U-shaped, the screws pass through the bracket 12 and are fixed with the threaded holes or nuts in the U-shaped groove of the bracket, so that the clamping member 5 can be fixed on the drawer body 2 without passing through the drawer body, so that the inside of the drawer body 2 is smooth and flat. The drawer body 2 is then tightened to the locking cam 324 and the locking cam 324 is engaged with the locking cam 324.

[0042] In some embodiments, the drawer body 2 is fixed on the drawer front shell, and the contact surface of the drawer body 2 with the drawer front shell is provided with a fixing portion in the direction of the external extension of the drawer body 2, and the fixing portion is provided with a threaded hole, and the screw is fixed to the drawer front shell after passing through the threaded hole. In summary, the bottom of the drawer body 21 is designed with a U-shaped bracket 21 and an externally extended fixing portion, so that after the drawer body 21 is fixedly installed, there are no screws or threaded holes inside the drawer body 21 for placing items, and the inside is flat and smooth without protruding foreign matter or groove design, which is very convenient to use.

[0043] At present, most drawer mechanisms usually use physical handles to achieve opening and closing. After closing the drawer body, the drawer body is locked by a lock. When the drawer is in a locked state, it is necessary to unlock it before pulling out the drawer body. This kind of drawer mechanism uses an external handle, which is not only easy to touch by mistake, but also accompanied by the opening and closing of the lock when opening and closing the drawer, which is inconvenient to use.

[0044] To solve this problem, an embodiment of the drawer mechanism 100 further includes a spring lock mechanism 4. Figures 5 to 7 The spring lock mechanism 4 is arranged between the guide rail 31 and the slide rail 32. The spring lock mechanism 4 has a locking state for locking the drawer body 2 and an unlocking state for ejecting the drawer body 2. When the drawer body 2 is pushed inward to a certain position, the spring lock mechanism 4 can automatically lock the drawer body 2. When the drawer body 2 is pressed again, the spring lock mechanism 4 can automatically release and eject the drawer body 2, thereby realizing a push-type switch.

[0045] Specifically, the spring lock mechanism 4 includes a fixing member 41, a sliding member 42 and an elastic member 43, wherein the fixing member 41 is fixed on the guide rail 31, the fixing member 41 is in a strip shape and extends along the length direction of the guide rail 31, and a latch 411 is provided on the side of the fixing member 41 away from the guide rail 31, and the latch 411 is provided in the middle of the fixing member 41. The sliding member 42 is movably sleeved on the fixing member 41, and the sliding member 42 is fixed with the guide rail 32 by snapping, the sliding member 42 is in a strip shape and the length of the sliding member 42 is less than the length of the fixing member 41, and a sliding groove is recessed on the side of the sliding member 42 facing the fixing member 41, and the latch 411 is embedded in the sliding groove. One end of the elastic member 43 is connected to the fixing member 41, and the other end of the elastic member 43 is fixedly connected to the sliding member 42.

[0046] Among them, the pin 411 has a first position and a second position in the slide groove. When the pin 411 is in the first position, the sliding member 42 can slide freely. When the pin 411 slides to the second position, the pin 411 locks the sliding member 42. At this time, the elastic member 43 is in a compressed state. When the drawer body 2 is pressed again, the pin 411 is pulled out from the second position and slides back to the first position under the action of the elastic member 43 to unlock.

[0047] The specific working principle of the spring-lock mechanism 4 is as follows: when the drawer body 2 is in an unlocked state, the pin 411 is in the first position of the slide slot, and the sliding member 42 can slide freely. When the drawer body 2 is pushed inward, the drawer body 2 drives the slide rail 32 to slide, and the slide rail 32 then drives the sliding member 42 to slide, thereby causing the pin 411 and the sliding member 42 to move relative to each other. After the pin 411 slides to the second position of the slide slot, it is locked with the sliding member 42, and the drawer body 2 is locked. At this time, the elastic member 43 is in a compressed state. When the drawer body 2 is pressed again, the pin 411 is automatically withdrawn from the second position and slides back to the first position under the elastic force of the elastic member 43 to unlock, thereby realizing the push-type switch of the drawer body 2.

[0048] Reference Figure 7The slide groove includes a first sub-slide groove 421, a second sub-slide groove 422, a third sub-slide groove 423 and a fourth sub-slide groove 424. The extension direction of the first sub-slide groove 421 and the second sub-slide groove 422 is consistent with the movement direction of the slide rail 32, and the length of the first sub-slide groove 421 is greater than the length of the second sub-slide groove 422. The third sub-slide groove 423 is arranged at one end of the second sub-slide groove 422 to connect the first sub-slide groove 421 and the second sub-slide groove 422. The fourth sub-slide groove 424 is arranged at the other end of the second sub-slide groove 422 to connect the first sub-slide groove 421 and the second sub-slide groove 422.

[0049] Among them, the side of the third sub-slot 423 facing away from the pushing direction is set to the first inclined surface 4231 and the second inclined surface 4232, and an inwardly concave snap-in position is formed between the first inclined surface 4231 and the second inclined surface 4232; the side of the fourth sub-slot 424 facing away from the pushing direction is set to the third inclined surface 4241; a blocking block 425 is convexly provided in the third sub-slot 423; the blocking block 425 is at least partially arranged opposite to the first sub-slot 421; and the side of the blocking block 425 facing the first sub-slot 421 is set to the fourth inclined surface 4251.

[0050] When the drawer body 2 is in the unlocked state, the latch 411 is embedded in the first sub-slot 421. When the drawer body 2 drives the sliding member 42 to slide inward, the latch 411 slides along the first sub-slot 421 until it abuts against the blocking block 425. The latch 411 slides into the buckle position under the guidance of the fourth inclined surface 4251 of the blocking block 425. At this time, the sliding member 42 is in the locked state and the elastic member 43 is in the compressed state. When the drawer body 2 is pressed again, the latch 411 slides down to the second sub-slot 422 under the guidance of the second inclined surface 4232. The sliding member 42 moves outward under the action of the elastic member 43. The latch 411 slides along the second sub-slot 422 until it slides into the fourth sub-slot 424 under the guidance of the third inclined surface 4241 and returns to the first sub-slot 421.

[0051] Reference Figure 8 A block 323 is protruding from one side of the slide rail 32 facing the sliding member 42 , and a buckle notch 426 is provided at one end of the sliding member 42 facing the pushing direction, and a retractable hook 427 is provided in the buckle notch 426 .

[0052] When the sliding member 42 is in an unlocked state, the hook 427 is in a retracted state, the slide rail 32 and the sliding member 42 are independent of each other, and when the sliding member 42 slides inward, the block 323 is inserted into the buckle notch 426 and pushes the sliding member 42 inward. At this time, the hook 427 extends out and locks the block 323 to fix the slide rail 32 and the sliding member 42, thereby realizing the common sliding of the slide rail 32 and the sliding member 42.

[0053] Furthermore, a side of the fixing member 41 facing the sliding member 42 is recessed with a connected straight slot 412 and an arc slot 413. The arc slot 413 is arranged at one end of the straight slot 412 facing the pushing direction and is bent in the direction away from the slide rail 32. The extension and retraction direction of the hook 427 is the width direction of the straight slot 412 or the arc slot 413, and the hook 427 is partially embedded in the straight slot 412 or the arc slot 413.

[0054] When the sliding member 42 is in the unlocked state, the hook 427 slides to the arc slot 413 and contracts under the squeezing action of the side wall of the arc slot 413. When the sliding member 42 slides inward, the hook 427 gradually slides to the linear slot 412 and extends outward to abut against the inner wall of the linear slot 412, thereby locking the block 323.

[0055] In summary, the embodiment of the drawer mechanism 100 eliminates the physical handle, and when in use, the drawer can be quickly opened and closed by lightly pressing and pushing the drawer body 2, which is convenient and quick to use.

[0056] Reference Figure 5 and Figure 6 In one embodiment of the utility model, the slide rail 32 includes a first sub-slide rail 321 and a second sub-slide rail 322. The first sub-slide rail 321 is slidably mounted on the guide rail 31, and the second sub-slide rail 322 is slidably mounted on the first sub-slide rail 321, and the second sub-slide rail 322 is fixedly arranged at the bottom of the drawer body 2. At this time, the drawer body 2 is fixedly connected to the second sub-slide rail 322 through the clamping member 5, and the spring lock mechanism 4 is arranged between the guide rail 31 and the second sub-slide rail 322. In this embodiment, the slide rail 32 is arranged as the first sub-slide rail 321 and the second sub-slide rail 322, so as to extend the sliding path of the slide rail 32, thereby extending the sliding path of the drawer body 2, so that the drawer body 2 opens a larger opening when it is opened, which is convenient for taking and placing objects.
