It also enhances the locking reliability of the locking structure, provides strong resistance to forced entry, and has good anti-disengagement performance, thus improving the safety and reliability of the drawers when they are closed.

Description

Technical Field

[0001] This application relates to the field of storage tools technology, specifically to a locking structure for a drawer box. Background Technology

[0002] Drawer chests are an important part of home and tool storage. A drawer chest consists of a chest body and drawers within it. Currently, most drawer chests use a locking mechanism between the chest body and the drawers to lock individual drawers. This structure is relatively complex, has high manufacturing costs, and offers weak resistance to forced entry and poor anti-detachment performance. Furthermore, the drawers are inconvenient to pull out, seriously affecting work efficiency and safety. Utility Model Content

[0003] In view of this, this application provides a locking structure for a drawer box, which is simple in structure, easy to operate, and has good security and reliability.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A locking structure for a drawer box, the drawer box including a drawer box body and at least one drawer disposed within the drawer box body, the drawer having a pulled-out state and a closed state;

[0006] The latching structure has a locked state and an unlocked state, and includes a latching member that is movably connected to the front of the drawer body;

[0007] When all drawers in the same row are closed and the latching mechanism is locked, the latch is located directly in front of all drawers in the same row, and the latch prevents any drawer in the same row from moving in the pull-out direction; when the latching mechanism is unlocked, the latch is not located directly in front of any drawer in the same row, and the latch allows any drawer in the same row to move in the pull-out direction.

[0008] Optionally, the front of the drawer body includes a box opening that allows the drawer to move therein and at least one edge surface disposed at the edge of the box opening; when the locking structure is in the locked state, the locking member is located directly in front of the box opening, and when the locking structure is in the unlocked state, the locking member is located directly in front of at least one of the edge surfaces.

[0009] Optionally, the edge surface includes at least one vertical surface and at least one horizontal surface, the vertical surface and the horizontal surface forming the box opening; when the locking structure is in the unlocked state, the locking element is located directly in front of at least one of the vertical surfaces.

[0010] Optionally, the locking element includes a locking part and two sliding parts respectively connected to both ends of the locking part. When the locking structure is in the locked state, the locking part interferes with the drawer switching from the closed state to the pulled-out state. The two sliding parts are located on the upper and lower sides of the drawer respectively and are slidably connected to the drawer body.

[0011] Optionally, the locking member includes a force-applying part connected to the locking member, and the force-applying part can drive the locking member to move; when the locking structure is in the locked state, the force-applying part is also located in front of at least one of the edge surfaces.

[0012] Optionally, the latching structure further includes a first blocking part disposed on the edge surface. When the latching structure is in the unlocked state, the latching member is on the side away from the drawer from the first blocking part, and the first blocking part prevents the latching member from moving in the locking direction of the latching structure.

[0013] Optionally, the locking structure further includes a second blocking part, and the first blocking part is disposed on the drawer. When the locking structure is in the locked state, the locking member is on the side of the second blocking part away from the drawer body, and the second blocking part prevents the locking member from moving in the unlocking direction of the locking structure.

[0014] Optionally, the locking structure further includes a retaining structure, the retaining structure comprising:

[0015] A lock hole is provided on the drawer body and is located outside the sliding path of the sliding part;

[0016] The lock body is detachably connected to the lock hole. When the latch structure is in the locked state, the lock body abuts against the latch member on one side of the latch structure in the unlocking direction.

[0017] Optionally, the locking element can be slidably connected to the drawer body in the left-right direction of the drawer.

[0018] Optionally, the locking element is a wire lock.

[0019] Optionally, two locking structures are provided, with the locking elements of the two locking structures located at the front of the left and right sides of the drawer, respectively; when the drawer body has two rows of drawers, the two locking structures can lock the two rows of drawers respectively.

[0020] The drawer box locking structure provided in this application has a locking element that is movably set on the front of the drawer box body. When multiple drawer boxes are stacked vertically or horizontally, the unlocking and locking of the locking structure will not be affected. This allows for convenient pulling out and closing of the drawer. The structure is simple, the operation is convenient, and it helps to improve work efficiency. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] like Figures 1-8 As shown, this application embodiment provides a locking structure for a drawer box, applied to a drawer box. The drawer box includes a drawer box body 1 and at least one drawer 2 disposed within the drawer box body 1, that is, one or more drawers 2 are disposed within the drawer box body 1; the drawer 2 has a closed state and a pulled-out state, wherein the closed state of the drawer 2 refers to the state in which the drawer 2 is not pulled out from the box opening 101 of the drawer box body 1 and is located inside the drawer box body 1 (e.g., Figure 1 As shown in the figure, the pulled-out state of drawer 2 refers to the state in which drawer 2 is pulled out from inside the drawer box body 1.

[0038] like Figure 8 As shown, drawer 2 has a back panel 202, a front panel 203, a bottom panel 204, and two side panels 205. The two side panels 205 are connected between the back panel 202 and the front panel 203 to form a square area, which is located above the bottom panel 204. The left-right direction of drawer 2 is the arrangement direction of the two side panels 205. Figure 2 , 3 As shown in the X direction, the vertical direction of drawer 2 corresponds to the arrangement of the square area and the base plate 204. Figure 2 , 5 As shown in the Z direction, the direction in which drawer 2 is pulled out is from the back panel 202 to the front panel 203 of drawer 2, that is... Figure 3 , 6 Y direction shown.

[0039] The locking structure 13 includes a locking element 131, which is movably connected to the front of the drawer body 1. The locking structure 13 switches between an unlocked and locked state by the movement of the locking element 131 relative to the drawer body 1. The movement of the locking element 131 can be either a flipping action or a sliding action. Here, the front of the drawer body 1 has a box opening 101 for allowing the drawer 20 to be pulled out or closed, and the locking structure 13 is connected to the edge surface of the box opening 101 formed by the front of the drawer body 1.

[0040] During use, when all drawers 2 in the same row are closed and the locking structure 13 is locked, the locking element 131 is located directly in front of all drawers 2 in the same row, that is, on one side of the pull-out direction (Y direction) of all drawers 2 in the same row. This prevents any drawer 2 in the same row from moving in the pull-out direction, thus limiting all drawers 2 in the same row to the closed state. When the locking structure 13 is unlocked, the locking element 131 is not located directly in front of any drawer 2 in the same row, that is, on one side of the pull-out direction of all drawers 2 in the same row. This allows any drawer 2 in the same row to move in the pull-out direction, thus enabling all drawers 2 in the same row to switch between the pull-out and closed states. In this way, when multiple drawer bodies 1 are stacked vertically or horizontally, the unlocking and locking of the locking structure 13 will not be affected. This allows for convenient pulling out and closing of drawers 2, with a simple structure and convenient operation, which helps improve work efficiency.

[0041] It should be noted that all drawers 2 in the same column are arranged along the vertical direction (Z direction) of the drawer box body 1. When there is one column of drawers 2 on the drawer box body 1, the locking fastener 131 can lock all drawers 2 at the same time. When there are multiple columns of drawers 2 in the horizontal direction (X direction), there are multiple locking fasteners 131 in the horizontal direction (X direction). Each locking fastener 131 can lock all drawers 2 in one column individually. Multiple locking fasteners 131 are set corresponding to multiple columns of drawers 2.

[0042] In this embodiment, the front of the drawer body 1 includes a drawer opening 101 and at least one edge surface. The drawer opening 101 is used to accommodate the drawer 2 and allows the drawer 2 to move within the drawer opening 101. The edge surface is located at the four edges of the drawer opening 101. For example, four edge surfaces are provided, located at the top, bottom, left, and right edges of the drawer opening 101. When the locking structure 13 is in the locked state, the locking member 131 is located directly in front of the drawer opening 101 of the drawer body 1, so that the locking member 131 blocks the drawer 2 from moving in the pull-out direction within the drawer opening 101. When the locking structure 13 is in the unlocked state, the locking member 131 moves to the front of at least one edge surface of the drawer body 1, so that the locking member 131 can avoid the drawer 2, allowing the drawer 2 to move from the drawer opening 101 in the pull-out direction. In this way, by switching the locking fastener 131 between the front of the drawer box body 1 opening 101 and the front of the edge surface, the drawer 2 can be fully opened and fully closed relative to the drawer box body 1, which helps to improve the opening degree and closing tightness of the drawer 2.

[0043] The drawer body 1 has at least one vertical surface 102 and at least one horizontal surface 103 on its edge surface, forming the opening 101 of the drawer body 1. For example, two vertical surfaces 102 and two horizontal surfaces 103 are provided, with the two vertical surfaces 102 located on the left and right sides of the opening 101, and the two horizontal surfaces 103 located on the top and bottom sides of the opening 101. During use, when the locking structure 13 is locked, the locking element 131 is located directly in front of the opening 101 of the drawer body 1, preventing the drawer 2 from moving out of the opening 101. When the locking structure 13 is unlocked, the locking element 131 is located directly in front of the vertical surface 102 of the drawer body 1, allowing the drawer 2 to move out of the opening 101. In this way, the locking fastener 131 can switch between the opening 101 of the drawer body 1 and the front of the vertical surface 102 in the left and right directions. When the locking fastener 131 moves relative to the drawer body 1 with force, it has little impact on the force balance of the drawer body 1, which helps to prevent the drawer body 1 from tilting and collapsing.

[0044] In a specific embodiment, the locking element 131 can be slidably connected to the drawer body 1 in the left-right direction of the drawer 2. By sliding the locking element 131 relative to the drawer body 1 in the left-right direction, the locking element 131 is positioned directly in front of both the drawer opening 101 and the vertical surface 102 of the drawer body 1. Alternatively, the locking element 131 can be flipped and connected to the vertical surface 102 of the drawer body 1. By flipping the locking element 131 relative to the drawer body 1, the locking element 131 can be flipped to be partially positioned in front of the drawer opening 101, or flipped to be completely positioned in front of the vertical surface 102 of the drawer body 1.

[0045] In this embodiment, the locking structure 13 includes a locking member 131 and a first blocking part 104. The locking member 131 is disposed on the front of the drawer body 1 and can slide along the left and right direction of the drawer 2 to switch between a locked state and an unlocked state. For example, the two ends of the locking member 131 are located on the upper and lower sides of the drawer 2, respectively, and are slidably connected to the drawer body 1. The first blocking part 104 is disposed on the drawer body 1. Specifically, the first blocking part 104 can be located on the left or right side of the drawer 2 and is connected to the drawer body 1. That is, the first blocking part 104 is disposed on the edge surface of the drawer body 1. Specifically, the first blocking part 104 is disposed on the vertical surface 102 of the drawer body 1 and is close to the opening 101. The locking member 131 is slidably disposed on the horizontal surface 103. When the locking structure 13 is in the unlocked state, the locking member 131 is located on the side of the first blocking part 104 away from the drawer 2. The first blocking part 104 can prevent the locking member 131 from moving in the locking direction, thereby restricting the locking structure 13 to the unlocked state. In this way, by restricting the unlocked state of the locking structure 13 through the first blocking part 104, the unlocking reliability of the locking structure 13 can be improved. When it is necessary to pull out the drawer 2, there is no need to apply additional force to restrict the locking structure 13 to the unlocked state, which can conveniently open and close the drawer 2, saving time and effort and improving work efficiency.

[0046] The first blocking part 104 is a protrusion integrally formed on the drawer body 1. Third inclined surfaces are provided on both the left and right sides of the first blocking part 104, so that the cross-section of the first blocking part 104 gradually decreases in the pull-out direction of the drawer 2. When the locking member 131 moves in the unlocking or locking direction, the locking member 131 first abuts against the third inclined surface. Under the action of the third inclined surface, the locking member 131 slides along the third inclined surface, allowing it to pass over the first blocking part 104. Thus, under the action of the third inclined surface, the first blocking part 104 can both block the locking member 131 and allow the locking member 131 to pass over the first blocking part 104 when the user applies force. This improves structural reliability and also reduces the force required by the user during operation, achieving the purpose of saving effort.

[0047] It should be noted that, under the action of the third inclined surface, the locking element 131 and the first blocking part 104 will form a relative displacement in the pull-out direction of the drawer 2. Here, the locking element 131 can be displaced relative to the first blocking part 104 under its own elasticity, or it can be displaced relative to the first blocking part 104 through the connection of the elastic element to the drawer body 1. Alternatively, the first blocking part 104 can be displaced relative to the locking element 131 under its own elasticity, or it can be displaced relative to the locking element 131 through the connection of the elastic element to the drawer body 1.

[0048] In a preferred embodiment, the locking structure 13 further includes a second blocking part 208, which is disposed on the drawer 2. Specifically, the second blocking part 208 can be disposed on the left or right side of the front panel 203 of the drawer 2. When the locking structure 13 is in the locked state, the locking member 131 is located on the side of the second blocking part 208 away from the drawer body 1. The second blocking part 208 can prevent the locking member 131 from moving in the unlocking direction, thereby restricting the locking structure 13 to the locked state. In this way, by restricting the locked state of the locking structure 13 by the second blocking part 208, the locking reliability of the locking structure 13 can be improved. When the retaining structure described later is in the released state, the locking structure 13 can still be restricted to the locked state, improving the anti-shaking ability of the drawer 2 and preventing the drawer 2 from sliding out during the pulling process or on uneven ground, causing safety hazards such as tools scattering or tipping over.

[0049] The second blocking part 208 is a protrusion integrally formed into the drawer 2. Fourth inclined surfaces are provided on both the left and right sides of the second blocking part 208, so that the cross-section of the second blocking part 208 gradually decreases in the pull-out direction of the drawer 2. When the locking member 131 moves in the unlocking or locking direction, the locking member 131 first abuts against the fourth inclined surface. Under the action of the fourth inclined surface, the locking member 131 slides along the fourth inclined surface, allowing it to pass over the second blocking part 208. Thus, under the action of the fourth inclined surface, the second blocking part 208 can both block the locking member 131 and allow the locking member 131 to pass over the second blocking part 208 when the user applies force. This improves structural reliability and also reduces the force required by the user during operation, achieving the purpose of saving effort.

[0050] It should be noted that, under the action of the fourth inclined surface, the locking element 131 and the second blocking part 208 will form a relative displacement in the pull-out direction of the drawer 2. Here, the locking element 131 can be displaced relative to the second blocking part 208 under its own elasticity, or it can be displaced relative to the second blocking part 208 through the connection of the elastic element to the drawer body 1. Alternatively, the second blocking part 208 can be displaced relative to the locking element 131 under its own elasticity, or it can be displaced relative to the locking element 131 through the connection of the elastic element to the drawer body 1.

[0051] In this embodiment, the locking element 131 is slidably connected to the drawer body 1. By sliding the locking element 131 left and right relative to the drawer body 1, the locked state and the unlocked state can be switched. The structural form of the locking element 131 in this embodiment will be described in detail below.

[0052] In this embodiment, the locking member 131 includes a locking part 1311 and two sliding parts 1313. When the drawer 2 is in the closed state and the locking structure 13 is in the locked state, the locking part 1311 is located directly in front of the drawer body 1's opening 101 and abuts against one side of the drawer 2 in the pull-out direction (Y direction) to interfere with the drawer 2 switching from the closed state to the pull-out state, thereby locking the drawer 2 in the closed state. The two sliding parts 1313 are respectively connected to both ends of the locking part 1311, and are located on the upper and lower sides of the drawer 2, respectively, and connected to the horizontal surfaces 103 on the upper and lower sides of the drawer body 1. That is, the locking part 1311 is slidably connected to the drawer body 1 through the two sliding parts 1313. In this way, since the locking fastener 131 is connected to the upper and lower edges of the drawer body 1, the locking fastener 131 can interfere with all the drawers 2 in the same row and lock all the drawers 2 in the same row in the closed state. Moreover, the connection method of the locking fastener 131 is stable and reliable, which helps to improve the security and reliability of locking the drawers 2.

[0053] The locking element 131 may further include a force-applying part 1312, which is connected to the locking part 1311. The force-applying part 1312 protrudes from the locking part 1311 in the pull-out direction (Y direction) of the drawer 2. When the locking structure 13 is in the locked state, both the locking part 1311 and the force-applying part 1312 are located directly in front of the drawer opening 101 of the drawer body 1. When the locking structure 13 is in the unlocked state, both the locking part 1311 and the force-applying part 1312 are located directly in front of the vertical surface 102 of the drawer body 1. In this way, the force-applying part 1312 can drive the locking part 1311 to move in the left and right direction of the drawer 2. When the user applies force, due to the protruding design of the force-applying part 1312, the force-bearing surface is large and the force-bearing position is convenient for application, which helps to improve the convenience of unlocking and locking for the user.

[0054] like Figure 7 As shown, the locking part 1311, the sliding part 1313, and the force-applying part 1312 can be integrally formed, which facilitates processing and manufacturing, and also improves the structural strength of the locking element 131. For example, the locking element 131 can be set as a wire lock, that is, the locking part 1311, the sliding part 1313, and the force-applying part 1312 are all formed by bending a single steel wire. This wire lock has both a certain degree of deformation and good structural strength.

[0055] In the specific design, the drawer box body 1 contains multiple drawers 2, for example, two drawers 2 stacked vertically. Each drawer 2 has a second blocking part 208. The locking part 1311 engages with the second blocking parts 208 on both drawers 2. The force-applying part 1312 is correspondingly located in the area between the two second blocking parts 208 and is connected to the locking part 1311. Here, to facilitate the processing of the locking fastener 131, the locking part 1311 has two sections in the direction of the vertical stacking of the drawers 2, each corresponding to one of the two vertically stacked second blocking parts 208. The force-applying part 1312 is U-shaped and connects to the two sections of the locking part 1311.

[0056] In some preferred embodiments, the locking structure 13 includes a mounting base 105, which is disposed on the drawer body 1. Corresponding to the two sliding parts 1313, there are two mounting bases 105, located on the upper and lower horizontal surfaces 103 of the drawer body 1, respectively. The mounting base 105 is provided with guide holes extending in the left-right direction of the drawer 2, which is also the unlocking and locking direction of the locking structure 13. The sliding parts 1313 pass through and slide within the guide holes. The guide holes guide the movement of the sliding parts 1313, allowing them to slide smoothly and stably along the left-right direction of the drawer 2. Furthermore, the large contact area between the sliding parts 1313 and the guide holes improves the stability of the connection between the locking element 131 and the drawer body 1, thus enhancing the structural strength of the locking structure 13.

[0057] A third blocking part 1314 is provided at the end of the sliding part 1313 away from the locking part 1311. The outer diameter of the third blocking part 1314 is larger than the inner diameter of the guide hole. Under the connecting action of the sliding part 1313, the locking part 1311 and the third blocking part 1314 are located on both sides of the guide hole, with one moving away from the guide hole and the other moving closer to it. When the latching structure 13 is in the unlocked state, the third blocking part 1314 abuts against the end of the guide hole, that is, the third blocking part 1314 abuts against the mounting base 105, thereby restricting the sliding part 1313 from continuing to move in the unlocking direction of the latching structure 13. In this way, by setting the third blocking part 1314, the sliding part 1313 can be confined within the guide hole, preventing the sliding part 1313 from coming out of the guide hole, thereby maintaining the stability and reliability of subsequent locking.

[0058] In the specific design, the third blocking part 1314 includes a sleeve, which is fitted onto the end of the sliding part 1313 and is simultaneously connected to the sliding part 1313 and the sleeve by a pin, so that the sleeve and the sliding part 1313 are fixed together, thereby increasing the outer diameter of the end of the sliding part 1313.

[0059] In some embodiments, the locking structure 13 further includes a retaining structure disposed on the drawer body 1. The retaining structure has a retaining state and a released state. When the drawer 2 is in the closed state and the locking structure 13 is in the locked state, the retaining structure can switch to the retaining state to keep the locking structure 13 in the locked state. In this way, by maintaining the locked state of the locking structure 13 through the retaining structure, the locking reliability of the locking structure 13 can be improved, achieving dual locking of the drawer 10, with strong anti-forced opening capability and good anti-disengagement performance, which is beneficial to improving the safety and reliability of the drawer 2 in the closed state.

[0060] The retaining structure includes a lock hole 132 and a lock body. The lock hole 132 is located on the drawer body 1 and outside the sliding path of the sliding part 1313. For example, the lock hole 132 is located on the mounting base 105 and on one side of the guide hole. The lock body is detachably connected to the lock hole 132. When the lock body is not connected to the lock hole 132, the latching structure 13 can freely switch between a locked state and an unlocked state. When the lock body is connected to the lock hole 132 and the latching structure 13 is in the locked state, the lock body abuts against the sliding part 1313 in the unlocking direction of the latching structure 13 (i.e.,...). Figure 2 , 3 The sliding part 1313 is positioned on one side (in the X direction) to restrict its movement in the unlocking direction, thereby keeping the latch structure 13 in the locked state. In this way, by connecting the lock body and the lock hole 132, the latch structure 13 can be kept in the locked state, thus forming a double lock for the closed state of the drawer 2, improving the anti-theft performance.

[0061] It should be noted that the extension direction of the lock hole 132 (e.g., the Z direction) can intersect with the extension direction of the guide hole (e.g., the X direction). For example, the extension direction of the lock hole 132 can be perpendicular to the extension direction of the guide hole. In this way, when the lock body is connected in the lock hole 132, it can be better positioned on the extension path of the guide hole (i.e., on the sliding path of the sliding part 1313), improving the accuracy of the lock body position and maintaining the functional stability of the structure.

[0062] To further enhance the locking of drawer 2, two locking catches 131 are provided and arranged along the left-right direction (i.e., the X direction) of drawer 2. For example, the two locking catches 131 are symmetrically arranged, and one locking catch 131 is unlocked by moving to the left (i.e., the unlocking direction of this locking catch 131 is...). Figure 2 , 3 (In the left direction), another locking element 131 moves to the right to unlock (i.e., the unlocking direction of this locking element 131 is...). Figure 2 , 5 (Right direction in the middle). When drawer 2 is closed and the latch is locked, the two latches 131 abut against the left and right sides of drawer 2 respectively, interfering with the left and right sides of drawer 2 to restrict the movement of drawer 2 in the pull-out direction. In this way, the left and right balance of the latch structure 13 and the left and right balance of the drawer body 1 can be improved.

[0063] Correspondingly, the retaining structure has two configurations, one on the left and one on the right. The first blocking part 104 has two configurations on the left and one on the right, and the second blocking part 208 has two configurations on the left and one on the right. Moreover, there are two rows of drawers 2 in the left and right direction, and two locking fasteners 131 lock the two rows of drawers 2 respectively.
