Description

Technical Field

[0001] The utility model relates to the field of household electrical appliances, in particular to a lifting drawer of a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. The refrigerator has a compressor, an ice maker, a cabinet or box for ice making, and a storage box with a refrigeration device. With the development of the economy and the improvement of people's living standards, more and more home appliances have begun to enter people's daily lives. At present, refrigerators have gradually become one of the necessary appliances for many families. They can provide a lower temperature environment for food in the hot summer to extend the shelf life of food.

[0003] Users will place various items in the refrigerator, including but not limited to cosmetics, food and drinks, and these items placed in the refrigerator are at different heights, which causes a waste of the longitudinal space of the refrigerator and makes the original large volume low in utilization. Utility Model Content

[0004] The purpose to be achieved by the utility model is to provide a refrigerator lifting drawer to solve the problem of wasted longitudinal space when placing items of different heights in the refrigerator. By arranging a lifting frame and locking it through a locking mechanism after the lifting frame is lifted, the entire space is divided into upper and lower layers of space, thereby fully utilizing the longitudinal space.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a refrigerator lifting drawer, including a box body, a accommodating cavity opening forward is provided in the box body, a first placement plate is provided on the top surface of the accommodating cavity, and the characteristic is that the box body is slidably connected with a lifting frame that moves up and down and opens forward, the top surface of the lifting frame is a second placement plate, and a locking mechanism for locking the lifting frame after it is lifted to a specific position is provided on the box body outside the lifting frame, and after the lifting frame is lifted, a new placement space is formed between the first placement plate and the second placement plate.

[0006] After adopting the above technical scheme, the utility model has the following advantages: by lifting the lifting frame, the locking mechanism locks the lifting frame in a specific position, and the space above the lifting frame is divided into two layers, not only can items be placed on the second placement plate, but also a new placement space can be formed between the first placement plate and the second placement plate to place items, so as to place items of different heights; when it is necessary to place higher items, the locking mechanism can be opened, and the lifting frame can be retracted by its own weight, so that the longitudinal space on the second placement plate becomes larger, so that higher items can be placed.

[0007] Furthermore, the box body is provided with an interlayer opening upward, and the locking mechanism is placed in the interlayer.

[0008] By adopting the above-mentioned technical solution, the locking mechanism is placed in the interlayer, so that the locking mechanism will not be affected by external impurities such as dust, thereby extending the service life of the locking mechanism.

[0009] Furthermore, the lifting frame includes a side panel, and the locking mechanism includes a support block and a moving bar. The support block is fixed on the side panel, and a moving bar corresponding to the position of the support block is provided in the interlayer. The moving bar is provided with a through groove adapted to the support block. When the moving bar is in the first position, the through groove and the support block are arranged alternately, and when the moving bar is in the second position, the support block corresponds to and passes through the through groove.

[0010] By adopting the above-mentioned technical solution, by controlling the moving bar to switch between the first position and the second position, the support blocks on both sides of the lifting frame are supported on the moving bar, or pass through the through slot, so that the lifting frame can be locked and unlocked, which facilitates operation.

[0011] Furthermore, an elastic element is provided at one end of the moving bar, which has a tendency to keep the moving bar in the first position.

[0012] By adopting the above-mentioned technical solution, the elastic force of the elastic element makes the moving bar tend to maintain the first position, so that the moving bar can maintain the position of locking the lifting frame under normal circumstances, ensuring that the support block is always supported on the moving bar, thereby preventing the lifting frame from falling due to unexpected circumstances.

[0013] Furthermore, the support block is provided with a contact surface, and the contact surface is an inclined surface. When the lifting frame moves upward, the contact surface presses against the through slot and pushes the moving bar to the second position.

[0014] By adopting the above technical solution, the contact surface of the support block presses the through slot and pushes the moving bar to the second position, so that the lifting frame does not need to manually operate the position of the moving bar when rising, which facilitates the operation of the lifting frame.

[0015] Furthermore, there are three side panels, the support blocks are arranged on two opposite side panels, and multiple support blocks are arranged along the front-to-back direction, and a pair of movable bars are provided and arranged at relative positions of the support blocks.

[0016] By adopting the above-mentioned technical solution, a movable bar and a plurality of supporting blocks are arranged on two opposite side panels, so that the locking of the lifting frame is more stable and the problem of tilting is avoided.

[0017] Furthermore, a transmission plate is provided in the interlayer between the two moving bars, the middle position of the transmission plate is rotatably connected to the bottom wall of the interlayer, both ends of the transmission plate are abutted against the moving bars, and one of the moving bars is provided with a pressure piece at the end away from the elastic element. When the pressure piece squeezes the moving bar, the moving bar is moved to the second position, and the transmission plate is driven to rotate, pushing the other moving bar to move to the second position.

[0018] By adopting the above-mentioned technical solution, by pressing the pressure piece, the pressure piece can drive the moving bar to move to the second position, which is convenient for the user to operate the unlocking of the lifting frame. When the pressure piece squeezes the moving bar, the moving bar moves to the second position, and drives the transmission plate to rotate, pushing the other moving bar to move to the second position, so that the support blocks on both sides of the lifting frame pass through the through slots at the same time, so that the two sides of the lifting frame drop synchronously due to gravity, avoiding jamming.

[0019] Furthermore, a drawer which moves laterally and opens upward is provided at the opening of the accommodating cavity.

[0020] By adopting the above-mentioned technical solution, using a drawer in the accommodating cavity can make it more convenient to store and retrieve food.

[0021] Furthermore, when the lifting frame is closed, the drawer is inside the lifting frame.

[0022] By adopting the above technical solution, the drawer will not affect the lifting and lowering of the lifting frame.

[0023] Furthermore, a mezzanine is provided in the box body of the side wall of the lifting frame, and the locking mechanism is arranged on the side of the lifting frame. The locking mechanism includes a ratchet bar extending in the up and down directions fixedly provided on the side of the lifting frame, a pawl extending to the ratchet bar is hinged in the mezzanine, and a retaining spring is provided on the pawl, and the retaining spring has a tendency to push the pawl toward the ratchet bar. When the pawl abuts against the ratchet bar, the pawl restricts the ratchet bar and the lifting frame from moving downward, a shift rod is provided on the hinge axis of the pawl, a shift piece is provided at one end of the shift rod, and a first bevel gear is provided at the other end of the shift rod, and a rotating shaft is rotatably connected in the middle of the interlayer of the two bevel gears, and a second bevel gear matching the first bevel gear is installed on the rotating shaft.

[0024] The locking mechanism allows the lifting frame to be lifted to any position, thereby increasing the height selection of the lifting frame. The elastic force of the retaining spring pushes the pawl toward the ratchet bar, so that the pawl can be kept in the position engaged with the ratchet bar under normal circumstances, thereby preventing the lifting frame from falling due to unexpected circumstances. When it is necessary to unlock the engagement between the pawl and the ratchet bar, one of the paddles is pushed to rotate the pawl on the lever and disengage from the ratchet bar. At the same time, the first bevel gear on the lever is meshed with the second bevel gear on the rotating shaft, so that the other lever is also rotated to release the engagement between the pawl and the ratchet bar on the lever, so that the two sides of the lifting frame drop synchronously due to gravity, thereby avoiding jamming.

The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0037] Embodiment 1:

[0038] like Figures 1 to 7 As shown, in order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a refrigerator lifting drawer 6, including a box body 1, a accommodating cavity 11 opening forward is provided in the box body 1, and a first placement plate 12 is provided on the top surface of the accommodating cavity 11, characterized in that the box body 1 is slidably connected with a lifting frame 2 that moves up and down and opens forward, and the top surface of the lifting frame 2 is a second placement plate 21, and a locking mechanism 3 for locking the lifting frame 2 after it is lifted to a specific position is provided on the box body 1 outside the lifting frame 2, and after the lifting frame 2 is lifted, a new placement space is formed between the first placement plate 12 and the second placement plate 21.

[0039] After adopting the above technical scheme, the utility model has the following advantages: by lifting the lifting frame 2, the locking mechanism 3 locks the lifting frame 2 in a specific position, and the space above the lifting frame 2 is divided into two layers, not only can objects be placed on the second placement plate 21, but a new placement space can be formed between the first placement plate 12 and the second placement plate 21 to place objects, so that objects of different heights can be placed; when it is necessary to place higher objects, the locking mechanism 3 can be opened, and the lifting frame 2 can be retracted by its own weight, so that the longitudinal space on the second placement plate 21 becomes larger, so that higher objects can be placed.

[0040] Example 2: Based on Example 1,

[0041] like Figures 1 to 5 As shown, a sandwich layer 4 with an opening facing upward is provided in the box body 1 , and the locking mechanism 3 is placed in the sandwich layer 4 .

[0042] By adopting the above technical solution, the locking mechanism 3 is placed in the interlayer 4, so that the locking mechanism 3 will not be affected by external impurities such as dust, thereby extending the service life of the locking mechanism 3.

[0043] Furthermore, the lifting frame 2 includes a side panel 13, and the locking mechanism 3 includes a support block 31 and a moving bar 33. The support block 31 is fixed on the side panel 13, and a moving bar 33 corresponding to the position of the support block 31 is provided in the interlayer 4. A through groove 331 adapted to the support block 31 is provided on the moving bar 33. When the moving bar 33 is in the first position, the through groove 331 and the support block 31 are arranged alternately. When the moving bar 33 is in the second position, the support block 31 corresponds to and passes through the through groove 331.

[0044] By adopting the above-mentioned technical solution, by controlling the moving bar 33 to switch between the first position and the second position, the support blocks 31 on both sides of the lifting frame 2 are supported on the moving bar 33, or pass through the through groove 331, so that the lifting frame 2 can be locked and unlocked, which facilitates operation.

[0045] Specifically, the interlayer 4 of Example 1 is covered with a cover plate, so that the locking mechanism 3 is hidden in the interlayer 4 and the cover plate, so that the locking mechanism 3 is further protected from the influence of external dust and impurities, and the service life of the locking mechanism 3 is further extended.

[0046] Furthermore, an elastic element 34 is disposed at one end of the moving bar 33, which has a tendency to keep the moving bar 33 in the first position.

[0047] By adopting the above-mentioned technical solution, through the elastic force of the elastic element 34, the moving bar 33 has a tendency to maintain the first position, so that the moving bar 33 can maintain the position of locking the lifting frame 2 under normal circumstances, ensuring that the support block 31 is always supported on the moving bar 33, thereby preventing the lifting frame 2 from falling due to unexpected circumstances.

[0048] Furthermore, the support block 31 is provided with a contact surface 32 , and the contact surface 32 is an inclined surface. When the lifting frame 2 moves upward, the contact surface 32 presses against the through slot 331 and pushes the moving bar 33 to the second position.

[0049] By adopting the above technical solution, the contact surface 32 of the support block 31 presses the through groove 331 and pushes the moving bar 33 to the second position, so that the lifting frame 2 does not need to manually operate the position of the moving bar 33 when rising, which facilitates the operation of the lifting frame 2.

[0050] Furthermore, there are three side panels 13 , and the support blocks 31 are arranged on two opposite side panels 13 , and a plurality of support blocks 31 are arranged along the front-rear direction. A pair of moving bars 33 are provided, and are arranged at relative positions of the support blocks 31 .

[0051] By adopting the above-mentioned technical solution, a movable bar 33 and a plurality of supporting blocks 31 are arranged on two opposite side panels 13, so that the locking of the lifting frame 2 is more stable and the problem of tilting is avoided.

[0052] Furthermore, a transmission plate 35 is provided in the interlayer 4 between the two moving bars 33, and the middle position of the transmission plate 35 is rotatably connected to the bottom wall of the interlayer 4, and both ends of the transmission plate 35 are against the moving bars 33. One of the moving bars 33 is provided with a pressure piece 36 at the end away from the elastic element 34. When the pressure piece 36 squeezes the moving bar 33, the moving bar 33 is moved to the second position, and the transmission plate 35 is driven to rotate, pushing the other moving bar 33 to move to the second position.

[0053] Specifically, the pressure member 36 is cylindrical, and the direction of pressure application is the moving direction of the moving bar 33 .

[0054] In another embodiment, the pressure member 36 is provided with a pressing surface 361, and the pressure direction is perpendicular to the moving direction of the moving bar 33, and a reset spring 362 is installed at the bottom of the pressure member 36. When the pressure member 36 moves downward, the pressing surface 361 presses the moving bar 33 to move the moving bar 33 to the second position, and the reset spring 362 can reset the pressure member 36 upward.

[0055] By adopting the above-mentioned technical solution, by pressing the pressure piece 36, the pressure piece 36 can drive the moving bar 33 to move to the second position, which is convenient for the user to operate the unlocking of the lifting frame 2. When the pressure piece 36 squeezes the moving bar 33, the moving bar 33 is moved to the second position, and the transmission plate 35 is driven to rotate, pushing the other moving bar 33 to move to the second position, so that the support blocks 31 on both sides of the lifting frame 2 pass through the through groove 331 at the same time, so that the two sides of the lifting frame 2 drop synchronously due to gravity to avoid jamming.

[0056] Furthermore, a drawer 6 which moves laterally and opens upward is provided at the opening of the accommodating cavity 11 .

[0057] By adopting the above technical solution, using the drawer 6 in the accommodating cavity 11 can make it more convenient to store and retrieve food.

[0058] Furthermore, when the lifting frame 2 is closed, the drawer 6 is inside the lifting frame 2 .

[0059] By adopting the above technical solution, the drawer 6 will not affect the lifting and lowering of the lifting frame 2.

[0060] Example 3: Based on Example 1,

[0061] like Figure 6 to Figure 7 As shown, a sandwich 4 is provided in the box body 1 of the side wall of the lifting frame 2, and the locking mechanism 3 is arranged on the side of the lifting frame 2. The locking mechanism 3 includes a ratchet bar 37 extending in the up and down directions fixedly provided on the side of the lifting frame 2, and a pawl 38 extending to the ratchet bar 37 is hinged in the interlayer 4, and a retaining spring 39 is provided on the pawl 38. The retaining spring 39 has a tendency to push the pawl 38 onto the ratchet bar 37. When the pawl 38 abuts against the ratchet bar 37, the pawl 38 restricts the ratchet bar 37 and the lifting frame 2 from moving downward, and a lever 41 cover plate is provided on the hinge axis of the pawl 38; 5, the lever 41 cover plate; 5 One end is provided with a paddle 51, the lever 41 cover plate; 5 The other end is provided with a first bevel gear 52, and a rotating shaft 53 is rotatably connected in the middle of the interlayer 4 of the two bevel gears, and a second bevel gear 54 adapted to the first bevel gear 52 is installed on the rotating shaft 53.

[0062] The above-mentioned technical scheme is adopted, after the lifting frame 2 is lifted, the lifting frame 2 will not move downward by the engagement of the ratchet bars 37 and the pawls 38 on both sides of the lifting frame 2, and the lifting frame 2 will be fixed in the lifting position. The locking mechanism 3 can be used to lift the lifting frame 2 to any position, thereby increasing the height selection of the lifting frame 2, and the elastic force of the retaining spring 39 makes the pawl 38 push toward the ratchet bar 37, so that the pawl 38 can be kept in the position of engaging the ratchet bar 37 under normal circumstances, thereby preventing the lifting frame 2 from accidentally being lifted. In case of external fall, when it is necessary to unlock the engagement between the pawl 38 and the ratchet bar 37, one of the paddles 51 is pushed to make the pawl 38 on the lever 41 cover plate 5 rotate and disengage from the ratchet bar 37, and at the same time, the first bevel gear 52 on the lever 41 cover plate 5 and the second bevel gear 54 on the rotating shaft 53 are engaged, so that the other lever 41 cover plate 5 also rotates, so that the pawl 38 and the ratchet bar 37 on the lever 41 cover plate 5 are released, so that the two sides of the lifting frame 2 are synchronously lowered due to gravity to avoid jamming.

[0063] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
