Description

Technical Field

[0001] This application relates to the field of connection technologies, and more particularly to a connection component and a drawer box. Background Art

[0002] Most existing drawer boxes unlock multiple drawers simultaneously. Multiple drawers are stacked, and different types of items can be stored in the multiple drawers. The drawers and the drawer box are connected in the form of a locking tongue and a mating part. When locked, the locking tongue interferes with the mating part, and when unlocking, pressure needs to be applied to the locking tongue to release the interference between the locking tongue and the mating part.

[0003] However, during the unlocking process of the drawer, pressure needs to be continuously applied to the locking tongue to unlock the drawer relative to the drawer box. The operation is cumbersome, time-consuming and laborious, and the unlocking efficiency is relatively low. Summary of the Invention

[0004] In view of this, this application provides a connection component and a drawer box, which have a simple structure and are easy to operate.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A connection component for use in a drawer box, wherein at least one drawer is provided in the drawer box, the drawer has a closed state and a pulled-out state, and the connection component includes:

[0007] A locking structure having a locked state and an unlocked state, provided on the drawer box. When the locking structure is in the locked state, it interferes with the drawer moving from the closed state to the pulled-out state, and the locking structure can automatically maintain the locked state;

[0008] A holding structure provided on the drawer and the locking structure, and the holding structure can hold the locking structure in the unlocked state so that the drawer can move from the closed state to the pulled-out state.

[0009] Optionally, the locking structure includes a mating part provided on the drawer, a push-lock main body, and at least one locking tongue provided on the push-lock main body. The locking tongue is correspondingly arranged with the mating part, and the locking tongue is moved to lock / unlock the mating part;

[0010] When the locking structure is in the locked state, the mating part on the drawer in the closed state is locked with the corresponding locking tongue, and the drawer in the pulled-out state can move in the closing direction and lock the mating part with the corresponding locking tongue.

[0011] Optionally, the locking structure further includes a first elastic member, and the first elastic member is located between the push-lock main body and the drawer box and can drive the push-lock main body to move in the locking direction so that the locking structure automatically maintains the locked state.

[0013] Optionally, the holding structure includes a first holding portion provided on the drawer and a second holding portion provided on the latch tongue. When the latch structure moves to the unlocked state and the drawer is in the closed state, the second holding portion can move to interfere with the first holding portion, so that the latch structure is automatically held in the unlocked state.

[0014] Optionally, the latch structure further includes a second elastic member, and the second elastic member is provided between the push lock body and the latch tongue;

[0015] When the latch structure moves to the locked state, the second elastic member can drive the latch tongue to move and interfere with the engaging portion; when the latch structure moves to the unlocked state, the second elastic member can drive the second holding portion to move to interfere with the first holding portion.

[0016] Optionally, a first inclined surface is further provided on the drawer. When the holding structure holds the latch structure in the unlocked state, the drawer in the closed state moves along the pulling-out direction, and the latch tongue presses the second elastic member under the action of the first inclined surface to cancel the interference between the first holding portion and the second holding portion.

[0017] Optionally, a second inclined surface is provided on one side of the drawer facing the locking direction of the latch structure and / or on one side of the latch tongue facing the unlocking direction of the latch structure. When the latch structure moves along the unlocking direction, under the action of the second inclined surface, the second holding portion can cross over the first holding portion and interfere with the first holding portion to prevent the latch structure from moving along the locking direction.

[0018] Optionally, a third inclined surface is further provided on the drawer and / or the latch tongue. When the latch structure is in the locked state, the drawer in the pulled-out state moves along the closing direction, and the latch tongue presses the second elastic member under the action of the third inclined surface, and after the second elastic member rebounds, the drawer is locked.

[0019] Optionally, a locking block is provided on the drawer, wherein:

[0048] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0049] As Figures 1 - 18 shown, the embodiment of the present application provides a connection component for locking the drawer 1 in the drawer box 100. Among them, the drawer box 100 can be a container such as a toolbox, a tool box, a storage box, a storage basket, a roller box, a tool bag, etc. The drawer box 100 includes at least one drawer 1 provided inside the drawer box 100. The drawer 1 has a closed state and a pulled-out state. The closed state of the drawer 1 refers to the state where the drawer 1 is located inside the drawer box 100 (as Figure 18 shown), and the pulled-out state of the drawer 1 refers to the state where the drawer 1 is pulled out from the drawer box 100 (as Figure 10 shown).

[0050] As Figures 1 - 15 shown, the connection component includes a lock structure 2 and a retaining structure 3. Among them, the lock structure 2 has a locked state and an unlocked state. The lock structure 2 is provided on the drawer box 100. When the lock structure 2 is in the locked state, it interferes with the drawer 1 moving from the closed state to the pulled-out state, so that the drawer 1 cannot be pulled out from the drawer box 100; and when the lock structure 2 is in the unlocked state, the interference state of the lock structure 2 on the drawer 1 is released, and the drawer 1 can be pulled out from the drawer box 100 under the action of an external force. The lock structure 2 can automatically remain in the locked state. Further, the retaining structure 3 can keep the lock structure 2 in the unlocked state; when the drawer 1 is in the closed state, the retaining structure 3 can keep the lock structure 2 in the unlocked state, so that the drawer 1 can move from the closed state to the pulled-out state.

[0051] As Figures 1 - 15 shown, the lock structure 2 includes a mating part 11 provided on the drawer 1, a push lock body 21, and a lock tongue 22 provided on the push lock body 21. The lock tongue 22 can be locked with the mating part 11, so that the corresponding drawer 1 is in the locked state.

[0052] The mating portion 11 is provided on the side of the drawer 1 near the opening of the drawer box 100, and the push-lock main body 21 is also provided on the side of the drawer box 100 near its opening. When the drawer 1 is in the closed state and the lock structure 2 is in the locked state, the lock tongue 22 can interfere with the mating portion 11. At this time, the mating portion 11 is located on the side of the lock tongue 22 away from the opening of the drawer box 100, and the mating portion 11 and the lock tongue 22 interfere with each other through the contact of flat surfaces, thereby preventing the drawer 1 in the closed state from being pulled out; when the drawer 1 is in the pulled-out state, the lock tongue 22 cannot interfere with the mating portion 11.

[0053] The push-lock main body 21 is provided on the drawer box 100 and extends along the stacking direction of the drawer 1. The lock tongue 22 is provided on the side of the push-lock main body 21 close to the drawer 1, and the push-lock main body 21 can drive the lock tongue 22 to move. In this embodiment, when the push-lock main body 21 moves upward (unlocking direction), the mating portion 11 of the drawer 1 in the closed state does not interfere with the corresponding lock tongue 22; when the push-lock main body 21 moves downward (locking direction), the mating portion 11 of the drawer 1 in the closed state interferes with the corresponding lock tongue 22, and the drawer 1 cannot be pulled out.

[0054] The lock tongue 22 protrudes towards the drawer 1 and protrudes from the setting surface of the push-lock main body 21. There is one or more lock tongues 22, and there is at least one on the drawer 1 as well. The lock tongues 22 and the mating portions 11 provided on the drawer 1 are arranged in a one-to-one correspondence. That is to say, the number of lock tongues 22 is the same as that of the drawer 1, and one (as Figure 5 shown), two (as Figure 4 shown), three or more are provided. When the lock tongue 22 interferes with the corresponding mating portion 11, the drawer 1 in the closed state cannot be pulled out and opened. At this time, the lock structure 2 is in the locked state; when the lock tongue 22 does not interfere with the corresponding mating portion 11, the drawer 1 in the closed state can move from the closed state to the pulled-out state. At this time, the lock structure 2 is in the unlocked state. When the lock tongue 22 and the mating portion 11 interfere, the lock tongue 22 blocks the mating portion 11 at this time to prevent the drawer 1 from being pulled out; when the lock tongue 22 and the mating portion 11 do not come into contact, the corresponding lock tongue 22 will not block the mating portion 11, and thus will not prevent the drawer 1 from being pulled out / closed. In this way, by moving the lock tongue 22, the locking or unlocking of the mating portion 11 can be achieved, and the switching between the locked state and the unlocked state of the lock structure 2 can also be achieved. Here, through the arrangement of the lock tongues 22 and the mating portions 11 that can cooperate with each other, the locking and unlocking of the drawer 1 can be simply and conveniently achieved.

[0055] Further, a plurality of locking tongues 22 are provided on the pushing lock body 21, and the plurality of locking tongues 22 are drivingly connected to each other. Specifically, as can be seen from the above embodiment, the locking tongues 22 are arranged in one-to-one correspondence with the drawers 1, and the number of the locking tongues 22 is the same as that of the drawers 1. Here, by arranging a plurality of locking tongues 22 on a single pushing lock body 21 and drivingly connecting the plurality of locking tongues 22, when the pushing lock body 21 is moved to drive the locking tongues 22 to move to achieve the switching between the unlocked and locked states, the pushing lock body 21 will drive the plurality of locking tongues 22 to move synchronously. In this way, the plurality of drawers 1 can be unlocked or locked synchronously, thereby improving the unlocking and locking efficiency of the drawers 1. Among them, the arrangement direction of the plurality of locking tongues 22 is the same as the arrangement direction of the drawers 1.

[0056] Further, the lock buckle structure 2 further includes a second elastic member 23. The second elastic member 23 is arranged between the pushing lock body 21 and the locking tongue 22, and the second elastic member 23 can keep the locking tongue 22 automatically in the locked state. In this embodiment, as Figures 1 to 15 shown, the second elastic member 23 can be a partial plate body of the lock buckle structure 2, and this partial plate body is a plate body capable of elastic deformation. The second elastic member 23 is integrally formed with the pushing lock body 21. That is to say, the displacement of the locking tongue 22 arranged on the second elastic member 23 is driven by the self-deformation of the partial plate body; or, as Figure 16 and Figure 17 shown, the second elastic member 23 can also include a connecting plate movably connected (such as rotationally connected) to the pushing lock body 21, and an elastic member arranged between the connecting plate and the pushing lock body 21. The elastic member deforms elastically by itself to drive the locking tongue 22 arranged on the connecting plate to displace, and the elastic member can be a spring or a spring sheet, etc. By providing the second elastic member 23, the drawer 1 in the closed state can be in the locked state, and the drawer 1 can be automatically locked when it is moved from the pulled-out state to the closed state.

[0057] In this embodiment, the second elastic member 23 is located between the plurality of locking tongues 22 and the push lock body 21. Therefore, the second elastic member 23 can drive the locking tongue 22 to approach the drawer 1 by elastic deformation and automatically achieve locking with the matching portion 11. When the lock catch structure 2 moves to the locked state and the drawer 1 is in the closed state, the locking tongue 22 is driven by the second elastic member 23 to approach the matching portion 11 and finally moves to a position interfering with the matching portion 11. When the lock structure 2 moves to the locked state and the drawer 1 switches from the pulled-out state to the closed state, that is, when the drawer 1 is moving into the drawer box 100, since the lock tongue 22 is already located on the moving path of the matching part 11 driven by the second elastic member 23, the moving drawer 1 will apply a force on the lock tongue 22 away from the drawer 1, and the second elastic member 23 will elastically deform under the pressure of the drawer 1 to drive the lock tongue 22 to move in the direction away from the drawer 1. When the drawer 1 moves to the closed state, the drawer 1 no longer presses the second elastic member 23 to release the force applied to the lock tongue 22, and the lock tongue 22 will move again to the side where the drawer 1 is located under the action of the elastic force of the second elastic member 23 and interfere with the matching part 11. At this time, the lock tongue 22 is located on the side of the matching part 11 facing the direction of pulling out the drawer 1, and the lock structure 2 switches to the locked state. During this process, when there is only one locking tongue 22 set on the second elastic member 23, the second elastic member 23 can enable the single locking tongue 22 to individually lock a single drawer 1. When there are multiple locking tongues 22 set on the second elastic member 23, all drawers 1 in the closed state are locked under the synchronous drive of the second elastic member 23.

[0058] Furthermore, when the lock structure 2 is in a locked state, in order to facilitate the locking of a single drawer 1, a third inclined surface 13 is further provided on the drawer 1 or / and the lock tongue 22, and the third inclined surface 13 is provided on the side of the matching portion 11 away from the opening of the drawer box 100. The third inclined surface 13 can be provided on the drawer 1, or on the lock tongue 22, or the third inclined surface 13 can be provided on both the drawer 1 and the lock tongue 22. Figure 1 , Figure 2 and Figures 11 - 15As shown, when the latch structures 2 are all in the locked state, the locking tongue 22 is located on the moving path of the drawer 1. If the drawer 1 in the pulled-out state moves in the closing direction, the locking tongue 22 can be pushed away from the drawer 1 by the third inclined surface 13 provided on the drawer 1, and then the second elastic member 23 is pressed away from the drawer 1. At this time, the latch structure 2 switches from the locked state to the unlocked state; then as the drawer 1 continues to close, the locking tongue 22 passes over the engaging portion 11, and the second elastic member 23 that is no longer pressed by the drawer 1 rebounds to make the locking tongue 22 move to the moving path of the drawer 1 again. The locking tongue 22 is located on the side of the engaging portion 11 facing the pulling-out direction of the drawer 1. At this time, the closed drawer 1 is locked (that is, the locking tongue 22 will block the engaging portion 11 in the pulling-out direction to prevent the drawer 1 from being pulled open), and the latch structure 2 returns to the locked state again.

[0059] In this embodiment, by providing the third inclined surface 13 on the drawer 1 or / and the locking tongue 22, the drawer 1 can push the second elastic member 23 to rebound when closing, so that the locking tongue 22 located on the moving path of the drawer 1 can avoid the drawer 1, ensuring that the drawer 1 can be normally switched to the closed state (return to the closed position), and preventing the locking tongue 22 from blocking the closed drawer 1 and affecting the normal closing of the drawer 1. Alternatively, the avoidance action of the locking tongue 22 can also be achieved by applying an external force to the second elastic member 23 to move the locking tongue 22 away from the drawer 1.

[0060] In some embodiments, as Figures 6 - 15 shown, the latch structure 2 further includes a first elastic member 24. The first elastic member 24 is located between the lock-pushing main body 21 and the drawer box 100, and can drive the lock-pushing main body 21 to act in the locking direction, so that the latch structure 2 automatically maintains the locked state. Here, through the setting of the first elastic member 24, the drawer 1 in the closed state can be automatically locked, improving the convenience of using the drawer box 100, with a simple structure, high automation degree, and time and labor saving. Exemplarily, the first elastic member 24 can be a spring or a spring sheet and other structures. In this embodiment, both the second elastic member 23 and the first elastic member 24 are provided, so as to realize the automatic locking when the drawer 1 is in the closed state.

[0061] On the basis of providing the first elastic member 24, the connecting assembly further includes a holding structure 3. The holding structure 3 mainly prevents the latch structure 2 from rebounding and locking under the action of the first elastic member 24, so that the latch structure 2 remains in the unlocked state, facilitating the pulling out of any drawer 1 and one-handed operation. The holding structure 3 is provided on the drawer 1 and the latch structure 2. In some specific embodiments, as Figure 6 and Figure 7As shown in the figure, the retaining structure 3 includes a first retaining portion 31 provided on the drawer 1 and a second retaining portion 32 provided on the locking tongue 22. When the drawer 1 is switched from the closed state to the pulled-out state, first, the locking structure 2 needs to be switched from the locked state to the unlocked state. When the locking structure 2 moves to the unlocked state and the drawer 1 is in the closed state, the second retaining portion 32 can move in the unlocking direction to interfere with the first retaining portion 31. In this way, the first retaining portion 31 will block the second retaining portion 32 from automatically moving in the locking direction (i.e., cancel the automatic locking function of the locking structure 2), so as to block the locking structure 2 from moving to the position when it is in the locked state, so that the locking structure 2 is automatically maintained in the unlocked state, facilitating the drawer 1 to be pulled out. Further, when the drawer 1 is switched from the pulled-out state to the closed state, the locking structure 2 is automatically switched from the unlocked state to the locked state (i.e., cancel the function of maintaining the unlocked state of the locking structure 2), and maintains the locked state of the drawer 1. Here, through the settings of the first retaining portion 31 and the second retaining portion 32, when it is necessary to pull out the drawer 1, the locking structure 2 can be maintained in the unlocked state to ensure that the drawer 1 can be pulled out; and the retaining structure 3 can make the locking structure 2 automatically maintained in the unlocked state, so as to improve the automation degree of the retaining structure 3, with convenient operation, saving time and effort.

[0062] Specifically, in order to facilitate canceling the function of the retaining structure 3 to maintain the unlocked state, as Figure 6 shown Figure 7 in the figure, a first inclined surface 12 is further provided on the drawer 1. Specifically, during the process of switching the drawer 1 from the closed state to the pulled-out state, due to the setting of the first inclined surface 12, the interference between the first retaining portion 31 and the second retaining portion 32 will be canceled during any pulling process of the drawer 1. In this embodiment, the setting of the first elastic member 24 can make the locking structure 2 return to the locked position after the interference between the first retaining portion 31 and the second retaining portion 32 is canceled, so as to realize the automatic locking of the drawer 1 when the drawer 1 is switched from the pulled-out state to the closed state, improving the convenience when the drawer 1 is switched between the pulled-out state and the closed state; and when there are multiple drawers 1, the first elastic member 24 automatically maintains the locking structure 2 in the locked state, thus preventing other drawers 1 that do not need to be pulled out from being pulled out when pulling out one of the drawers 1 in the drawer box 100.

[0063] When the retaining structure 3 holds the latch structure 2 in the unlocked state, the drawer 1 in the closed state moves in the pulling-out direction, and the moving first inclined surface 12 pushes the locking tongue 22 to press the second elastic member 23, causing the second elastic member 23 to deform in the direction away from the drawer 1 to cancel the interference between the first retaining portion 31 and the second retaining portion 32. Specifically, when it is necessary to adjust the drawer 1 from the closed state to the pulled-out state, that is, when pulling the drawer 1 out of the drawer box 100, the operator applies a force to the latch structure 2 to move the latch structure 2 in the unlocking direction, so that the locking tongue 22 and the second retaining portion 32 move upward synchronously. The upward-moving locking tongue 22 no longer interferes with the mating portion 11, and the latch structure 2 switches from the locked state to the unlocked state. At the same time, the upward-moving second retaining portion 32 overlaps on the first retaining portion 31 (i.e., interferes with the first retaining portion 31), and the retaining structure 3 holds the latch structure 2 in the unlocked state. At this time, the operator applies a pulling force to the drawer 1, and the drawer 1 can move in the pulling-out direction. During the movement, the locking tongue 22 on the pulling-out path of the drawer 1 gradually approaches and abuts against the first inclined surface 12. The first inclined surface 12 abutting against the locking tongue 22 applies a force to the locking tongue 22, causing the locking tongue 22 and the second elastic member 23 to move to the side away from the drawer 1. At this time, the first retaining portion 31 and the second retaining portion 32 are disengaged from abutment, and the latch structure 2 moves in the locking direction under the drive of the first elastic member 24, causing the locking tongue 22 to drop. Although the dropped locking tongue 22 is at the same height as the mating portion 11, since the drawer 1 has been pulled out a certain distance, the mating portion 11 is already on the side of the locking tongue 22 facing the pulling-out direction, and the locking tongue 22 can no longer interfere with the mating portion 11, and the drawer 1 is no longer blocked by the locking tongue 22. After that, continuing to pull the drawer 1 can completely switch the drawer 1 to the pulled-out state. In this way, when switching the drawer 1 from the closed state to the pulled-out state, the interference between the first retaining portion 31 and the second retaining portion 32 can be simply and efficiently cancelled, and the pulling-out action of the drawer 1 is not affected. The operation is simple, time-saving and labor-saving. Exemplarily, the first retaining portion 31 is a certain surface of the drawer 1, and the second retaining portion 32 is a certain surface of the locking tongue 22 (such as the lower surface of the locking tongue 22). When the unlocking direction and the locking direction are in the up-down direction, when the latch structure 2 is in the locked state, the first retaining portion 31 is located above the second retaining portion 32, and the first retaining portion 31 and the second retaining portion 32 do not come into contact; when the latch is in the unlocked state, the second retaining portion 32 moves onto the first retaining portion 31, and the second retaining portion 32 abuts against the first retaining portion 31 to prevent the locking tongue 22 from moving down to the position when the latch structure 2 is in the locked state. With such a setting, it is more convenient to maintain the unlocked state of the latch structure 2. The structure is simple and the operation is convenient.

[0064] In some embodiments, such as Figure 6 and Figure 7As shown, when the buckle structure 2 is in the locked state, a second inclined surface 221 is provided on one side of the drawer 1 facing the locking direction of the buckle structure 2 and / or on one side of the locking tongue 22 facing the unlocking direction of the buckle structure 2. That is to say, the second inclined surface 221 can be provided on the drawer 1, or the second inclined surface 221 can be provided on the locking tongue 22, or the second inclined surface 221 can be provided on both the drawer 1 and the locking tongue 22. When the buckle structure 2 moves in the unlocking direction, under the action of the second inclined surface 221, the second holding portion 32 can cross over the first holding portion 31 and interfere with the first holding portion 31. Specifically, when it is necessary to switch the buckle structure 2 from the locked state to the unlocked state, the operator pulls up the buckle structure 2. Since the second inclined surface 221 is provided on the drawer 1 and / or the drawer 1, a force away from the drawer 1 will be applied to the locking tongue 22 under the action of the second inclined surface 221. In this way, the second elastic member 23 connected to the locking tongue 22 will undergo elastic deformation, driving the locking tongue 22 to move away from the drawer 1. At the same time, the locking tongue 22 will also move upward together with the buckle structure 2, so that the second holding portion 32 crosses over the first holding portion 31 and under the elastic force of the second elastic member 23, the locking tongue 22 will move towards the side where the drawer 1 is located, so that the straight surfaces between the second holding portion 32 and the first holding portion 31 are in butt-joint, so as to keep the buckle structure 2 in the unlocked state.

[0065] When the unlocking direction and the locking direction of the buckle structure 2 are in the up-and-down direction, in order to facilitate the upward movement of the buckle structure 2 to switch from the locked state to the unlocked state, so that the operator can perform the unlocking operation more labor-saving and conveniently, the top surface of the locking tongue 22 is set as the second inclined surface 221, so that the locking tongue 22 can better abut and slide against the lower end of the first holding portion 31 and smoothly leap above the first holding portion 31, providing convenience for the holding structure 3 to hold the buckle structure 2 in the unlocked state.

[0066] Among them, when the drawer 1 needs to be switched from the pulled-out state to the closed state, during the process of the drawer 1 moving into the drawer box 100, the drawer 1 will apply a force to the buckle structure 2, so that the buckle structure 2 moves or undergoes elastic deformation away from the drawer 1, and the buckle structure 2 is driven by the first elastic member 24 to switch to the locked state, so as to realize the automatic switching of the buckle structure 2 to the locked state during the closing process of the drawer 1. When the drawer 1 needs to be switched from the closed state to the pulled-out state, the operator applies a force to the buckle structure 2, causing the buckle structure 2 to displace or undergo elastic deformation, so that the buckle structure 2 switches to the unlocked state. At this time, the holding structure 3 will apply a holding force to the buckle structure 2 in the unlocked state, so that the buckle structure 2 is held in the unlocked state, so that the drawer 1 can be switched from the closed state to the pulled-out state, so as to smoothly realize the pulling out of the drawer 1.

[0067] In the above structure, the lock structure 2 is kept in the unlocked state by the retaining structure 3, and the drawer 1 can be pulled out of the drawer box 100 without applying a retaining force to the lock structure 2, which is conducive to realizing the rapid pulling out of the drawer 1 in the drawer box 100, single-handed operation, simple operation, time saving and labor saving. In addition, when the drawer 1 is pushed into the specified position, the lock tongue 22 of the lock structure 2 will automatically interfere with the matching part 11 of the drawer 1 to realize the automatic locking of the drawer 1; this design not only enhances the safety of the drawer 1, prevents the drawer 1 from being pulled out inadvertently, but also saves the cumbersome steps of manual locking for the user; the introduction of the automatic locking function makes the use of the drawer 1 more intelligent and humane, and improves the user's experience. In addition, the retaining structure 3 can keep the lock structure 2 in the unlocked state, so that the user can easily perform single-handed operation; this design not only simplifies the opening and closing process of the drawer 1, but also improves the convenience and efficiency of the operation; the user does not need to laboriously find or adjust the position of the lock, and can quickly complete the locking and unlocking of the drawer 1, thereby saving time and energy.

[0068] It should be noted that the moving direction of the drawer 1 when switching between the closed state and the pulled-out state is different from the moving direction of the locking structure 2 when switching between the locked state and the unlocked state. There is an angle between the two directions, and the preferred angle between the two directions is 90 degrees. This can improve the stability of the locking structure 2 in limiting the drawer 1.

[0069] It should also be noted that the pull-out direction of the drawer 1 is Figure 10 In the direction indicated by the arrow A, the closing direction of drawer 1 is Figure 10 In the direction indicated by the arrow B, the unlocking direction of the lock structure 2 is Figure 10 In the direction indicated by the arrow C, the locking direction of the locking structure 2 is Figure 10 The direction indicated by the arrow D is away from the drawer 1. Figure 10 The direction indicated by arrow E.

[0070] In some embodiments, Figure 1 and Figure 2As shown in the figure, a locking block 14 is provided on the drawer 1. The mating portion 11 is a part or surface of the locking block 14 facing the pulling direction of the drawer 1. The third inclined surface 13 is the surface of the locking block 14 facing the closing direction of the drawer 1. And the mating portion 11 is the first straight surface on the locking block 14. Correspondingly, when the drawer 1 is in the closed state and the locking structure 2 is in the locked state, the surface of the locking tongue 22 close to the mating portion 11 is the second straight surface. At this time, if a force is applied to the drawer 1 in the pulling direction of the drawer 1, the first straight surface will abut against the second straight surface to prevent the drawer 1 with the first straight surface from moving, so as to achieve the purpose of locking. Here, by providing the locking block 14, the purpose of locking can be efficiently achieved, and the structure is simple, saving time and effort. In addition, the first holding portion 31 is located on one side of the locking block 14 facing the pulling direction of the drawer 1 and on one side of the locking block 14 facing the unlocking direction of the locking structure 2. The first inclined surface 12 is located on the side of the first holding portion 31 in the closing direction of the drawer 1. Through the above settings, the settings of the first inclined surface 12, the first holding portion 31, the mating portion 11 and the third inclined surface 13 can be made more compact, and the locking structure 2 can be efficiently switched between the unlocked state and the locked state. The holding structure 3 can keep the locking structure 2 automatically in the unlocked state, improving the automation degree when the drawer 1 is pulled out and closed, and the structure is simple.
