Description

Technical Field

[0001] The utility model relates to the technical field of cabinet fittings, in particular to a connecting piece for a drawer and a cabinet. Background Technique

[0002] In the cabinet products of furniture, the cabinet is often designed as a high-drawer style. The common high-drawers are full-cover high-drawers. The high-drawer cooperates with other drawers in the cabinet to form drawers for accommodating different objects. Other drawers in the cabinet can be called inner drawers. Among them, the high-drawer is generally used to store items such as pots, pans, and oil drums with larger volume or heavier weight. Other drawers as inner drawers are generally used to store items such as bowls, chopsticks, knives, and forks with smaller volume and / or higher usage frequency. By using the combination of the high-drawer and other drawers, a cabinet with a large storage capacity and high space utilization rate can be provided. In addition, in actual use, the usage frequency of the inner drawer is often higher than that of the high-drawer.

[0003] Reference Figure 1 , Figure 1 The arrow in shows the pulling direction of pulling out the high-drawer or the inner drawer. From left to right in the figure, it schematically shows the process of pulling out the high-drawer and the inner drawer in sequence. In the existing cabinet and high-drawer, in order to be able to pull out the inner drawer (i.e., the inner drawer) inside, generally handles are respectively installed on the outer surface of the high-drawer (i.e., the high-drawer) and the outer surface of the inner drawer. First, the high-drawer is pulled out through the handle, and then after the inner drawer is exposed, the handle on the inner drawer is operated to pull out the inner drawer. Therefore, in order to pull out the inner drawer from the cabinet, at least two operations are required. Similarly, in order to push the inner drawer back into the cabinet to close it, at least two operations are also required, and it is impossible to pull out and push back the inner drawer in one step, resulting in inconvenient use.

[0004] In order to realize pulling out the high-drawer and the inner drawer together, it is necessary to connect the high-drawer and the inner drawer through a connecting piece. However, the existing connecting pieces for realizing this function often cannot realize automatic disconnection and automatic locking, and require the user to operate manually for the second time. For example, by pressing to release the blocking of the inner drawer by the blocking part on the connecting piece to realize disconnection. Similarly, manual pressing again or other physical operations are required to realize re-locking. The existing connecting pieces cannot realize the automatic disconnection and reconnection of the connecting piece during the process of pulling out and pushing back the high-drawer and the inner drawer at one time, but require the user to operate multiple times, which is troublesome to operate and the user experience is not high.

[0005] In addition, since the existing cabinets are respectively provided with handles on the high-drawer and the inner drawer, in the prior art, there is no connecting piece designed for the high-drawer that can pull out and push back the inner drawer at one time. Moreover, one type of existing connecting piece for connecting drawers is that the connecting piece is clamped on the board of the drawer (such as the side board or the outer surface board) through the gap on the connecting piece. This means that the connecting piece can only be aimed at a board with a certain thickness and cannot adapt to boards with different thicknesses, and does not have universality and generality. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a connecting piece for a drawer and a cabinet body, which can solve the problems described in the background art.

[0007] The technical solution for achieving the purpose of the present utility model is as follows: A connecting piece for a drawer includes a first component and a second component. The first component includes a first installation part and a first connection part, and the second component includes a second installation part and a second connection part. The first connection part and the second connection part can be mutually converted between separation and connection. The first installation part is used to connect with an external first target object, and the second installation part is used to connect with an external second target object.

[0008] Further, when the first connection part and the second connection part are in connection, the first connection part and the second connection part are snap-connected.

[0009] Further, the first connection part includes a male snap part, the first installation part includes a fixing plate, the male snap part and the fixing plate are connected together. The second installation part includes a bottom plate, and the second connection part includes a pressing piece and an elastic piece. The pressing piece and the elastic piece are both fixedly connected to the same side of the bottom plate. The pressing piece and the elastic piece both extend along a direction away from the bottom plate. The pressing piece and the elastic piece are arranged vertically, so as to form an open space between the pressing piece and the elastic piece. The pressing piece and / or the elastic piece has elasticity.

[0010] Further, the male snap part is movably connected to the fixing plate, and the male snap part can freely slide along the axial direction of the fixing plate.

[0011] Further, the male snap part includes a connecting part and a protruding part connected together. The connecting part and the protruding part are fixedly connected together and form an L shape. A plurality of convex columns are arranged on the connecting part, and the convex columns are spaced apart. The convex columns extend towards the fixing plate. A plurality of guiding grooves are also dug in the groove of the fixing plate. The convex columns are used to extend into the guiding grooves and can slide along the axial direction of the guiding grooves, so that the male snap part is movably connected to the fixing plate.

[0012] The protruding part extends towards one side of the fixing plate, and the protruding part can be engaged in the open space.

[0013] Further, the connecting part is a vertical plate, the protruding part is a horizontal plate, and a male convex head protruding upwards is further provided at one end of the horizontal plate away from the vertical plate. A female convex head protruding downwards is further provided at one end of the pressing piece away from the bottom plate. The male convex head and the female convex head can be mutually engaged together.

[0014] Furthermore, the elastic sheet includes a first part, a second part and a third part connected in sequence along a direction away from the bottom plate, the first part and the third part are arranged tilted downward, and the second part is arranged horizontally. When the male convex stud head and the female convex stud head are engaged with each other, the bottom of the transverse plate abuts against the second part.

[0015] Furthermore, the first mounting portion further comprises a buffer column, which is protrudingly fixed on the front end of the fixing plate and has elasticity.

[0016] A cabinet body comprises a main cabinet, a first drawer, a second drawer and a connecting piece. The first drawer and the second drawer are movably mounted on the main cabinet, the first component is mounted on the second drawer, and the second component is mounted on the first drawer.

[0017] Furthermore, the first drawer includes an outer panel and an inner drawer, the second drawer includes an outer panel and a high drawer, the inner drawer and the high drawer are arranged in layers on the main cabinet, and the inner drawer and the high drawer are movably installed on the main cabinet so that the inner drawer and the high drawer can be close to and away from the main cabinet, and the heights of the first component and the second component are consistent.

[0018] Beneficial effects of the utility model: the utility model can realize the synchronous pulling out and pushing back of the high drawer and the inner drawer, and the connecting piece can automatically separate and reconnect after being pulled out a certain distance and pushed back a certain distance, realizing the automatic disengagement and re-locking function. The user does not need to operate the connecting piece, the operation is simpler, and the user experience is high. In addition, it is also possible to pull out and push back the high drawer and the inner drawer at one time, with a small number of operations. And the connecting piece can be applied to all cabinets, with better versatility and universality. The connecting piece is applied to the cabinet, which can ensure that the high drawer and the inner drawer are pulled out or pushed back smoothly and synchronously. In addition, not only is there no need to set a handle on the high drawer and the inner drawer, which can avoid the use of additional components, but the connecting piece itself has a simple component structure, strong practicality and low cost.

Detailed implementation mode

[0032] The following further describes the present utility model in conjunction with the attached drawings and specific implementation schemes:

[0033] As Figures 1 - 7 shown, a connecting piece for a drawer includes a first component and a second component, and the first component and the second component are detachably connected together. The first component includes a first mounting part and a first connecting part, the second component includes a second mounting part and a second connecting part, the first connecting part and the second connecting part are detachably connected together, the first mounting part is used to connect with an external first target object to mount the first component on the first target object, and the second mounting part is used to connect with an external second target object to mount the second component on the second target object. When the first connecting part and the second connecting part are connected together, the first target object and the second target object are connected together through the connecting piece. When the first connecting part and the second connecting part are disassembled and in a separated state, the first target object and the second target object are in a separated state, that is, in a non - connected state.

[0034] It should be noted that the first connecting part and the second connecting part are detachably connected together, which means that the first connecting part and the second connecting part include at least two connection relationships and can be converted between these two connection relationships: separation and connection together. The separated connection relationship means that the first connecting part and the second connecting part can be separated. For example, the first connecting part can be detached from the second connecting part, or the second connecting part can be detached from the first connecting part. The detached first connecting part and second connecting part are in a separated state, that is, in a non-connected state. Figure 2 The schematically shown first connecting part and second connecting part are in a separated state. The connection-together connection relationship means that the first connecting part and the second connecting part can be connected together, that is, the separated first connecting part and second connecting part are reconnected together. Figure 5 The schematically shown first connecting part and second connecting part are in a connected-together state. The connection method can be any one of snap connection, snap fit, inlay, etc., as long as this connection method can enable one of the first connecting part and the second connecting part to be separated and reconnected together under the pulling of an external force.

[0035] Reference Figure 2 , for example, the first connecting part includes a male snap member 3, and the first mounting part includes a fixing plate 1. The male snap member 3 and the fixing plate 1 are fixedly or detachably connected together. The fixing plate 1 is a flat plate-like structure. The male snap member 3 includes a connecting part and a protruding part. The connecting part and the protruding part are fixedly connected together and form an L shape. A groove is dug at the back end of the fixing plate 1. The size and shape of the groove are adapted to the size and shape of the connecting part of the male snap member 3, so that the male snap member 3 can be better connected to the fixing plate 1. The surface of the non-groove part at the back end of the fixing plate 1 is flush with the surface of the male snap member 3. The protruding part protrudes on one side of the fixing plate 1, that is, the protruding part extends towards one side of the fixing plate 1.

[0036] , for example, the first mounting part further includes a buffer post 2. The buffer post 2 is fixedly protruded on the front end of the fixing plate 1, that is, fixed on the end face opposite to the back end. The buffer post 2 can be made of silica gel or other flexible components with a certain elasticity. The buffer post 2 can be entirely made of silica gel (i.e., flexible component), or only the part that plays a buffering role can be made of silica gel, and other parts can be made of hard materials. For example, it can be made of high-hardness plastic. The buffer post 2 plays a buffering role. When the fixing plate 1 is installed and connected to the first target object as the first mounting part, and the second component is also installed and connected to the second target object, when the second target object and the first target object are connected together, the buffer post 2 can prevent the second target object from directly touching the first target object and avoid damage such as impact caused by the second target object to the first target object, thereby playing a buffering role.

[0037] Exemplarily, one or more through holes are also pre-dug on the fixing plate 1, and the through holes can be used to install fasteners such as screws, bolts, and screws, so as to fix or detachably install the fixing plate 1 on the first target object.

[0038] Exemplarily, the male fastener 3 and the fixing plate 1 are movably connected or detachably connected together, and the male fastener 3 can freely slide along the axial direction of the fixing plate 2.

[0039] In actual use, other connection methods can also be adopted for the protruding part and the connecting part. For example, the two can be connected together by using fasteners, or connected together by welding, etc., which are not limited herein.

[0040] Exemplarily, the male fastener 3 includes a vertical plate 31 and a horizontal plate 32, and the vertical plate 31 and the horizontal plate 32 are fixedly connected together, and the vertical plate 31 and the horizontal plate 32 can be of an integral structure. The vertical plate 31 can serve as the connecting part, and the horizontal plate 32 can serve as the protruding part. One end of the horizontal plate 32 away from the vertical plate 31 is also provided with a male convex head 321 protruding upward.

[0041] Exemplarily, refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 , a number of convex columns 311 are also installed on the vertical plate 31 of the male fastener 3, and the convex columns 311 are arranged at intervals. The convex columns 311 are fixedly connected with the vertical plate 31 or are of an integral structure. The convex columns 311 extend towards the fixing plate 1 and protrude from one side of the vertical plate 31. A number of guiding grooves 11 are also dug in the groove of the fixing plate 1, and the convex columns 311 and the guiding grooves 11 correspond one by one. The convex columns 311 are used to extend into the guiding grooves 11 and can slide along the axial direction of the guiding grooves, so that the male fastener 3 is movably installed on the fixing plate 1. The convex columns 311 slide downwards under the action of their own gravity until the convex columns 311 slide to contact the lower bottom wall of the guiding groove 11. At this time, there is a gap between the lower edge of the fixing plate 1 and the upper edge of the horizontal plate 32. Figure 6 The male fastener 3 shown in is sliding downwards, and the convex column 311 contacts the lower bottom wall of the guiding groove 11 on the fixing plate. The male fastener 3 shown in is lifted upwards again to the initial position. At this time, the male convex head 321 and the female convex head 411 are snap-connected together.

[0042] The second component includes a female snap member 4, and the female snap member 4 includes a pressing piece 41, a bottom plate 42, and an elastic piece 43. The second mounting portion includes the bottom plate 42, and the second connecting portion includes the pressing piece 41 and the elastic piece 43. Both the pressing piece 41 and the elastic piece 43 are fixedly connected to the same side of the bottom plate 42, and the pressing piece 41, the elastic piece 43, and the bottom plate 42 may be an integral structure. Both the pressing piece 41 and the elastic piece 43 extend in a direction away from the bottom plate 42, and the pressing piece 41 and the elastic piece 43 are arranged vertically, so as to form an open space between the pressing piece 41 and the elastic piece 43. The transverse plate 32 can extend into the open space to realize the connection between the first component and the second component. When the transverse plate 32 extends into the open space, the transverse plate 32 and the pressing piece 41 are engaged with each other, so that the first connecting portion and the second connecting portion are connected together.

[0043] Wherein, at least one of the pressing piece 41 and the elastic piece 43 has elasticity, that is, at least one of the pressing piece 41 and the elastic piece 43 has elasticity.

[0044] One end of the pressing piece 41 away from the bottom plate 42 is further provided with a downwardly protruding female convex head 411, and the male convex head 321 and the female convex head 411 can be engaged with each other. Figure 5 In [description], the transverse plate 32 extends into the open space. In this state, the male convex head 321 and the female convex head 411 are engaged with each other.

[0045] At least one of the pressing piece 41 and the elastic piece 43 has elasticity. Under an external force, the transverse plate 32 moves towards the open space. This acting force can cause extrusion on the pressing piece 41 and / or the elastic piece 43. Under the extrusion, in the vertical direction (i.e., the up and down direction), the pressing piece 41 swings upward and / or the elastic piece 43 swings downward, so that the male convex head 321 of the transverse plate 32 can be squeezed into the open space, thereby realizing the engagement connection between the male convex head 321 and the female convex head 411.

[0046] Exemplarily, the elastic piece 43 includes a first portion 431, a second portion 432, and a third portion 433 that are sequentially connected in a direction away from the bottom plate 42. The first portion 431 and the third portion 433 are inclined downward, and the second portion 432 is horizontally arranged. Such a setting is beneficial to the smooth sliding of the transverse plate 32 into the open space. When the transverse plate 32 slides into the space and the male convex head 321 and the female convex head 411 are engaged with each other, the bottom of the transverse plate 32 abuts against the second portion 432.

[0047] Exemplarily, the inclination degrees of the first portion 431 and the second portion 432 are the same, that is, their inclination rates are the same.

[0048] Exemplarily, the pressing piece 41 is arranged obliquely downward, and the degree of inclination is less than that of the elastic piece 43. At least a part of the end of the pressing piece 41 close to the elastic piece 43 is in a horizontal state, so that at least a part of the open space formed between the pressing piece 41 and the elastic piece 43 is a horizontal space, facilitating the lateral plate 32 to slide into the open space.

[0049] Exemplarily, a plurality of through holes are also pre-dug on the bottom plate 42, so that the bottom plate 42 can be installed on the second target object through fasteners such as screws, bolts, and screws.

[0050] Exemplarily, it includes two elastic pieces 43. The two elastic pieces 43 are arranged at intervals on both sides of the pressing piece 41. When the lateral plate 32 extends into the open space, the lateral plate 32 abuts against the two elastic pieces 43.

[0051] The connecting piece provided in this embodiment can be directly attached to the surface of the drawer (tall drawer or inner drawer) through the first mounting portion and the second mounting portion, without being clamped to the thickness of the board through a gap like a certain type of traditional connecting piece. Therefore, the connecting piece of this embodiment can be applied to any drawer, as long as the drawer can provide an installation surface, and has strong versatility and universality.

[0052] As Figures 8 - 12 As shown, the present utility model also provides a cabinet body, which includes a main cabinet 6, an inner drawer 5, a tall drawer 7, and the connecting piece. The inner drawer 5 includes an outer board and an inner drawer, and the tall drawer 7 further includes an outer panel 71. The inner drawer and the tall drawer 7 are arranged at intervals and in layers on the main cabinet 6. The inner drawer and the tall drawer 7 are both movably installed on the main cabinet 6, so that the inner drawer and the tall drawer 7 can approach and move away from the main cabinet 6, thereby realizing pulling out and pushing back the inner drawer and the tall drawer 7 into and out of the main cabinet 6. Figure 8 In, the inner drawer and the tall drawer 7 are pushed back and retracted into the main cabinet 6. Figure 9 In, the inner drawer and the tall drawer 7 are pulled out of the main cabinet 6.

[0053] It should be noted that the cabinet body provided in this embodiment only takes the tall drawer 7 and the inner drawer as examples. In actual use, it is not limited to being applied to the tall drawer 7 and the inner drawer, nor is it limited to being applied to the tall drawer 7 of the cabinet. This connecting piece can be applied to the drawers in any field, including the application field for synchronously pulling out and pushing back two drawers (the first drawer, the second drawer). The connecting piece can be used for connection and then assembled into a cabinet body. For example, it can be applied to the drawers of a bathroom cabinet, a storage cabinet, or other types of cabinet fields.

[0054] It should also be noted that the tall drawer 7 can also be replaced with a low drawer or other types of drawers. Here, the tall drawer 7 is a drawer type with a relatively high height, and the height of the tall drawer 7 is not limited to a certain height threshold. The height of the tall drawer 7 depends on the height of the drawer side.

[0055] The first component of the connecting piece is installed on the high drawer 7, and the second component is installed on the inner drawer 5, so as to realize the synchronous pulling out and pushing back of the inner drawer 5 and the high drawer 7 through the connecting piece. Specifically, the fixing plate 1 is fixed or detachably installed on the inner side of the outer panel 71 of the high drawer 7 through fasteners, and the transverse plate 32 protrudes towards the outer panel of the inner drawer 5. The bottom plate 42 is fixed or detachably installed at the bottom of the inner drawer, and the pressing piece 41 and the elastic piece 43 extend out of one side of the outer panel and are exactly opposite to the fixing plate 1. The height of the transverse plate 32 is the same as the height of the open space formed between the pressing piece 41 and the elastic piece 43, that is, the heights of the first component and the second component are the same, so that the transverse plate 32 can extend into or withdraw from the open space under the action of an external force, realizing the connection and separation of the inner drawer 5 and the high drawer 7.

[0056] In order to avoid the need to pull out the inner drawer 5 at least twice, such a problem can be avoided through the connecting piece. During actual use, when both the inner drawer 5 and the high drawer 7 are assembled in the main cabinet 6, and the first component and the second component of the connecting piece are also respectively installed on the high drawer 7 and the inner drawer 5. The inner drawer 5 and the high drawer 7 are both pushed back in place, and at this time the first component and the second component are connected together, that is, the transverse plate 32 extends into the open space. When it is necessary to pull out the inner drawer 5, the user applies an external force to the outer panel 71 of the high drawer 7. For example, the hand directly acts on the outer panel 71 or the handle on the outer panel 71, so as to pull out the high drawer 7 from the main cabinet 6. During the pulling out process of the high drawer 7, the first component and the second component of the connecting piece first maintain the connection state, so that the high drawer 7 can drive the inner drawer 5 to be pulled out synchronously, realizing the one-time pulling out of the inner drawer 5. When the inner drawer 5 is completely pulled out (referring to the state before it cannot be moved forward any further and is pulled out), since the inner drawer 5 stays in this position, when the external force continues to act on the high drawer 7 and pull it outwards, this acting force acts on the first component, causing the first component and the second component to separate, so that the high drawer 7 can be pulled out continuously, so as to avoid the inner drawer 5 blocking the high drawer 7 in the height direction and facilitating the user to pass through the inner drawer 5 and be able to operate the items in the high drawer 7. For example, it is convenient to take or put the relevant items in the high drawer 7. Refer to Figure 9 and Figure 10 , Figure 9 Figure Figure 10 is a schematic diagram of the state where the inner drawer 5 just reaches the completely pulled out position,

[0057] When the high drawer 7 and the inner drawer 5 are both pulled out (including partial or full pull-out), and the user wishes to push the inner drawer 5 and the high drawer 7 back, the user directly acts on the high drawer 7, and the high drawer 7 is pushed back towards the main cabinet 6. When the high drawer 7 is pushed back until the fixed plate 1 on the connecting piece touches the outer plate of the inner drawer 5, the high drawer 7 pushes the inner drawer 5 to move synchronously towards the main cabinet 6. When the inner drawer 5 is fully retracted (referring to the previous state where it can no longer move forward and is retracted), the high drawer 7 continues to move forward under the action of an external force, the transverse plate 32 of the connecting piece extends into the open space, the first part and the second part are connected together again, and the high drawer 7 is also fully retracted into place.

[0058] During the above process, the separation of the first part and the second part occurs at the moment when the inner drawer 5 is fully pulled out, and the connection of the first part and the second part occurs at the moment when the inner drawer 5 is fully retracted into place. In another alternative embodiment, it can also occur at the moment when the inner drawer 5 reaches other positions. For example, when the inner drawer 5 is pulled out partially, that is, any position in the middle of being fully pulled out, the first part and the second part are separated. Similarly, when the inner drawer 5 starts to retract to any position from fully retracted, the first part and the second part are reconnected together.

[0059] Through the connecting piece provided in this embodiment, when the high drawer 7 synchronously pulls out the inner drawer 5 and reaches the fully pulled-out position, the first part and the second part of the connecting piece can automatically disconnect, that is, the male convex head 321 and the female convex head 411 are disengaged from each other and are separated. At this time, the male snap member 3 slides downwards under its own gravity until the convex column 311 touches the bottom wall of the lower end of the guiding groove 11 on the fixed plate. Conversely, when the inner drawer 5 reaches the fully retracted position, the first part and the second part of the connecting piece can automatically reconnect, that is, the male convex head 321 and the female convex head 411 are snap-connected together. Among them, the elastic piece 43 contacts the transverse plate 32 and generates a frictional force, and the direction of this frictional force is inclined, so that a vertical component force can be decomposed. This component force drives the male snap member 3 to slide upwards, that is, the convex column 311 slides upwards along the guiding groove 11, so that the male convex head on the transverse plate 32 moves upwards a certain distance and engages with the female convex head 411 together, realizing the connection of the first part and the second part. Thus, the connecting piece has the functions of automatic unlocking and automatic locking, and can realize that the inner drawer 5 can automatically disengage from the high drawer 7, and can be re-automatically locked and connected together after being pushed back after disengagement.

[0060] Exemplarily, in order to enable the inner drawer 5 and the upper drawer 7 to be pulled out and retracted synchronously, connectors of other structures can be adopted. For example, the connector includes a first component and a second component that are always connected together, and the first component and the second component can slide relative to each other to approach and move away from each other. When the first component and the second component approach each other, the upper drawer 7 is allowed to approach the inner drawer 5 until the upper drawer 7 and the inner drawer 5 move synchronously. When the upper drawer 7 and the inner drawer 5 move synchronously, the first component and the second component stop sliding relative to each other. Similarly, when the first component and the second component move away from each other, the upper drawer 7 is allowed to move away from the inner drawer 5 until the upper drawer 7 and the inner drawer 5 move synchronously. When the upper drawer 7 and the inner drawer 5 move synchronously, the first component and the second component stop sliding relative to each other. The relative sliding between the upper drawer 7 and the inner drawer 5 can adopt the prior art. For example, a track is installed on the upper drawer 7, and the inner drawer 5 is slidably installed on the track, so that the relative sliding between the two can be achieved. Since the specific structure for achieving relative sliding is the prior art, it will not be elaborated here.

[0061] In another example, the connector includes a first component, a second component, and a flexible member. The first component is fixed on the upper drawer 7, the second component is fixed on the inner drawer 5, and both ends of the flexible member are fixedly connected to the first component and the second component. The flexible member can be a bendable telescopic belt, a flexible rope, or other bendable and straightenable telescopic members. When the flexible member is straightened under an external force and the external force acts on the upper drawer 7, the upper drawer 7 can drive the inner drawer 5 to be pulled out synchronously. When the external force acts on the upper drawer 7 and pushes the upper drawer 7 inward, the flexible member bends until the first component and the second component come into contact, and then the upper drawer 7 can push the inner drawer 5 inward synchronously, so as to synchronously push both the upper drawer 7 and the inner drawer 5 back into the main cabinet 6. Similarly, the inner drawer 5 and the upper drawer 7 can be pulled back and pushed back in one operation.

[0062] Among them, the first component and the second component can be fixed columns. The structures of the first component and the second component in this example can be different from those of the first component and the second component shown in Figure 2 The two ends of the flexible member are tied to the fixed columns, and the two fixed columns are respectively installed on the upper drawer 7 and the inner drawer 5, so that the upper drawer 7 and the inner drawer 5 can be pulled out and pushed back at one time.

[0063] It should be noted that in this embodiment, pulling out the upper drawer 7 and the inner drawer 5 at one time does not mean that the upper drawer 7 and the inner drawer 5 can only and must be pulled out and pushed back synchronously at one time, and they can also be pulled out separately. In addition, the upper drawer 7 and the inner drawer 5 can be synchronous throughout the movement of the inner drawer 5, or can be synchronous during part of the movement of the inner drawer 5, which can be selected according to needs.

[0064] The utility model can realize that during the synchronous pulling out and pushing back of the high drawer 7 and the inner drawer 5, the connecting piece can automatically separate and reconnect after pulling out a certain distance and pushing back a certain distance, realizing the functions of automatic detachment and re-locking. The user does not need to operate the connecting piece, the operation is simpler, and the user experience is better. In addition, it can also realize the one-time pulling out and pushing back of the high drawer 7 and the inner drawer 5, with fewer operation times. And the connecting piece can be applied to all cabinets, having better versatility and universality. When the connecting piece is applied to the cabinet, it can ensure that the high drawer 7 and the inner drawer 5 are pulled out or pushed back smoothly and synchronously. In addition, not only does it not need to set handles on the high drawer 7 and the inner drawer 5, which can avoid using additional components, but also the structure of the components of the connecting piece itself is simple, with strong practicability and low cost.
