[0035] The following is a further detailed description of an interlocking structure and a stacking tool box proposed by the utility model in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description.

[0036] Example 1

[0037] See also Figure 1-4, an interlocking structure, used for detachable connection of a first component 2 and a second component 3 stacked up and down, the first component 2 is at the lower part of the second component 3, and the interlocking structure 1 is arranged on both sides of the first component 2 and the second component 3. The first component 2 and the second component 3 can be a tool box for storing parts or a storage box for storing items in home life, which is not limited here, and can be any connection between two components that need to be stacked.

[0038] Specifically, the interlocking structure 1 includes a base 12, a locking member 11 and a driving member 13;

[0039] The base 12 is detachably connected to the first component 2, the locking member 11 is hinged to one side of the base 12 via a rotating shaft 16, a first elastic member 14 is provided on the base 12, one end of the first elastic member 14 is connected to the base 12, and the other end of the first elastic member 14 is connected to the locking member 11;

[0040] The driving member 13 is connected to the second component 3 through the second elastic member 15. The driving member 13 is configured to move upward relative to the second component 3. The driving member 13 can move upward relative to the second component 3. The second elastic member 15 is configured to resist the second component 3 from moving upward. When the external force for the driving member 13 to move upward disappears, the second elastic member 15 drives the driving member 13 to return to its initial state. A protruding wedge block 1301 is provided at the lower part of the driving member 13. The wedge block 1301 is configured to drive the locking member 11 to rotate in a direction away from the first component 2. The first elastic member 14 is configured to resist the locking member 11 from rotating in a direction away from the first component 2. At this time, the driving member 13 moves upward relative to the second component 3.

[0041] A protruding block 32 is provided on the side of the second component 3 . When the first component 2 and the second component 3 are in a connected state, the block 32 is engaged with the locking member 11 .

[0042] The interlocking structure 1 provided in this embodiment is used for detachably connecting the first component 2 and the second component 3, and the interlocking structure 1 includes a base 12, a locking member 11 and a driving member 13. The base 12 is detachably connected to the first component 2, and the locking member 11 is arranged on the upper part of the base 12 and is hinged to the base 12 through a rotating shaft 16, so that after the base 12 is connected to the first component 2, the locking member 11 can rotate relative to the base 12. The driving member 13 is connected to the second component 3, and the driving member 13 is movably arranged relative to the second component 3 in the vertical direction. A protruding wedge block 1301 is arranged at the lower part of the driving member 13, and a protruding clamping block 32 is arranged on the side of the second component 3. When the driving member 13 moves relative to the second component 3, the wedge block 1301 drives the locking member 11 to rotate in a direction away from the first component 2. Therefore, when the second component 3 needs to be stacked on the first component 2, since the wedge block 1301 arranged on the second component 3 has an inclined surface, the downward pressure of the wedge block 1301 will drive the locking member 11 to rotate in the direction close to the first component 2. At this time, due to the reaction force of the locking member 11, the driving member 13 will move upward relative to the second component 3. When the second component 3 is in stable contact with the first component 2, the force exerted on the wedge block 1301 disappears. Since the first elastic member 14 arranged on the base 12 can drive the locking member 11 to rotate in the direction close to the first component 2 until it returns to its initial state, the clamping block 32 is clamped on the locking member 11 to fix the second component 3, thereby realizing the second component 3 and the first component 2. fixed connection, and when the locking member 11 rotates toward the initial state, due to the action of the second elastic member 15 arranged between the driving member 13 and the second member 3, the driving member 13 can be driven to move downward relative to the second member 3 and return to the initial state; if the second member 3 needs to be moved away from the first member 2, the driving member 13 is moved upward relative to the second member 3 while moving the second member 3, so that the wedge block 1301 drives the locking member 11 to rotate in the direction away from the first member 2, so that the block 32 disengages from the locking member 11, and then the second member 3 is separated from the first member 2. After the force applied to the locking member 11 disappears, due to the action of the first elastic member 14, the locking member 11 is driven to return to the initial state.

[0043] A simple structure is used to realize the detachable connection of the stacked first component 2 and the second component 3. When one person stacks the second component 3 on the first component 2, the second component 3 can be driven to rotate in the direction away from the first component 2 by the weight of the second component 3 or the operator slightly exerts force, so that the wedge block 1301 with an inclined surface can make the locking member 11 rotate in the direction away from the first component 2, so that the second component 3 can be completely stacked on the first component 2. At this time, the first component 2 can support the second component 3, and the force of the wedge block 1301 disappears, and then the force of the wedge block 1301 on the locking member 11 also disappears. At this time, the locking member 11 is driven to restore to the initial state under the elastic force of the first elastic member 14, just to engage the clamping block 32 on the second component 3, so as to realize the fixation of the second component 3 and the first component 2. Moreover, the above-mentioned interlocking structure 1 is provided on both sides of the second component 3 and the first component 2, so that the second component 3 can be firmly fixed on the first component 2, and even if the first component 2 is moved, the second component 3 will not slip or shake. At the same time, one person can complete the separation and fixation of the first component 2 and the second component 3, and the operation is convenient.

[0044] In order to facilitate the upward movement of the second component 3 in the upper position, a third groove 1302 can be provided on the driving member 13 for the operator to hold the second component 3 by hand. By holding the third groove 1302, the second component 3 can be conveniently moved and the driving member 13 can be moved upward.

[0045] In a preferred embodiment, the locking member 11 includes a locking shaft 1101 and a hinge plate 1102 fixedly connected to the locking shaft 1101, and the hinge plate 1102 is hinged to the base 12 via a rotating shaft 16;

[0046] When the first component 2 and the second component 3 are in a locked state, the locking shaft 1101 is stuck on the block 32, and the wedge 1301 is located at the lower part of the locking shaft 1101. Since the upper and lower surfaces of the wedge 1301 are both inclined surfaces, when the first component 2 and the second component 3 need to be separated, the second component 3 is moved away, and the driving member 13 moves upward at the same time, and the wedge 1301 moves upward with the driving member 13. Since the upper surface of the wedge 1301 is an inclined surface, the wedge 1301 gives the locking shaft 1101 to rotate in the direction away from the first component 2, so that the block 32 is separated from the locking shaft 1101, and the first component 2 and the second component 3 are separated; after the separation, the external force on the locking shaft 1101 disappears, and due to the action of the first elastic member 14, the locking member 11 is driven to return to its initial state;

[0047] When the second component 3 needs to be stacked on the first component 2, the second component 3 moves downwardly toward the first component 2. When the lower surface of the wedge block 1301 contacts the locking shaft 1101, as the second component 3 continues to move downwardly toward the first component 2, the lower surface of the wedge block 1301 applies a force to the locking shaft 1101 to rotate away from the first component 2 until the lower surface of the second component 3 is completely in contact with the upper surface of the first component 2. Then, the downward movement of the second component 3 stops, and the force of the wedge block 1301 on the locking shaft 1101 disappears. When the locking shaft 1101 returns to its initial state due to the action of the first elastic member 14, the locking shaft 1101 is hooked on the clamping block 32.

[0048] Another purpose of designing the locking shaft 1101 is to reduce the friction between the locking shaft 1101 and the wedge block 1301. Because the locking shaft 1101 is a cylinder with a smaller diameter and the outer surface is a circular surface, when the wedge block 1301 moves up or down, the friction between the inclined surface and the cylinder is relatively small.

[0049] In this embodiment, in order to facilitate the locking shaft 1101 to be hung on the clamping block 32, the hinge plate 1102 is set at the center of the locking shaft 1101, and other positions of the locking shaft 1101 can be used to press the clamping block 32. A first hinged fixing block 1204 and a second hinged fixing block 1205 are set on the base 12, and the rotating shaft 16 passes through the first hinged fixing block 1204, the hinged plate 1102 and the second hinged fixing block 1205 in sequence, and the rotating shaft 16 is also rotatably connected to the two ends of the base 12.

[0050] Furthermore, both ends of the locking shaft 1101 extend downward and bend to form a first bending shaft 1103, and the bottom end of the first bending shaft 1103 extends and bends along the axis of the locking shaft 1101 toward a direction away from the locking shaft 1101 to form a second bending shaft 1104;

[0051] The second bending shaft 1104 is rotatably connected to the base 12 .

[0052] The purpose of the above-mentioned bending design is to ensure the stability of the entire interlocking structure 1. When in the locked state, the locking shaft 1101 is hung on the block 32. The locking shaft 1101 is located on the upper part of the block 32 and the wedge block 1301 and tightly presses the block 32 to prevent the second component 3 from shaking. If the hinge plate 1102 is connected to the base 12 alone, the block 32 may not be pressed very stably. In particular, when the second part is separated from the first component 2, the block 32 and the wedge block 1301 are both in an upward trend. If the hinge plate 1102 is connected to the base 12 alone, the locking shaft 1101 may be unstable. After connecting both ends of the locking shaft 1101 to the base 12, the entire interlocking structure 1 can be made more stable.

[0053] In a preferred embodiment, a fixing groove 1201 is provided on the base 12, and the first elastic member 14 is installed in the fixing groove 1201. One end of the first elastic member 14 is fixedly connected to the inner wall of the fixing groove 1201, and the other end of the first elastic member 14 abuts against the side of the hinge plate 1102. When the locking shaft 1101 rotates away from the first component 2, the lower part of the hinge plate 1102 moves toward the direction close to the first component 2, thereby compressing the first elastic member 14. After the force applied to the locking shaft 1101 disappears, the compressed elastic member drives the hinge plate 1102 to return, so that the locking member 11 returns to its initial state.

[0054] Taking into account that the force-bearing area of ​​the hinge plate 1102 is relatively small, a push block 1202 is also provided on the base 12 which is movable relative to the base 12. The push block 1202 is fixedly connected to one end of the first elastic member 14 away from the fixed groove 1201, and the side surface of the push block 1202 opposite to the surface connected to the first elastic member 14 abuts against the side surface of the hinge plate 1102, so that the hinge plate 1102 abuts against the push block 1202, and the first elastic member 14 is connected to the push block 1202, thereby increasing the force-bearing surface.

[0055] The locking shaft 1101 rotates in the direction of the first elastic member 14 toward the first member 2 and returns to the initial state to prevent the first elastic member 14 from excessive rotation. A limit plate 1206 is set on the base 12, and the limit plate 1206 is configured to limit the rotation of the hinge plate 1102 so that the hinge plate 1102 and the locking shaft 1101 rotate to the initial state and stop.

[0056] In another preferred embodiment, first grooves 21 are provided on both sides of the first component 2, and slide rails 22 are provided on the wall of the first groove 21. Correspondingly, a slide groove 1203 is provided on the base 12 that matches the wall of the first groove 21; or

[0057] A slide groove 1203 is provided on the wall surface of the first groove 21, and correspondingly, a slide rail 22 is provided on the base 12 that matches the wall surface of the first groove 21;

[0058] The slide rail 22 is connected to the slide groove 1203 to achieve a detachable connection between the first component 2 and the base 12 .

[0059] In this embodiment, the slide rail 22 is arranged on the wall surface of the first groove 21, and the slide groove 1203 is arranged on the base 12. After the slide rail 22 and the slide groove 1203 are connected, the vertical connection between the first component 2 and the base 12 is not firm. The cross-sectional shapes of the slide groove 1203 and the slide rail 22 are both designed to be "T"-shaped, which can prevent the upward force from separating the base 12 from the first component 2.

[0060] In order to prevent the base 12 from being separated from the left-right sliding rail 22 and the sliding groove 1203 of the first component 2, a first limiting protrusion is provided on the wall surface of the groove, and the first limiting protrusion is configured to prevent the base 12 from sliding out of the first groove 21.

[0061] In a preferred embodiment, second grooves 31 are provided on both sides of the second component 3, and the driving member 13 is installed in the second groove 31 to keep the side of the driving member 13 aligned with the side of the second component 3. A second elastic member 15 is also provided in the second groove 31, and the upper end of the second elastic member 15 is connected to the inner wall of the second groove 31, and the bottom end of the second elastic member 15 is connected to the driving member 13. When the driving member 13 moves upward, the second elastic member 15 is compressed. After the force for the driving member 13 to move upward disappears, the elastic action of the second elastic member 15 restores the driving member 13 to its initial state.

[0062] In a preferred embodiment, a second limit protrusion is provided on the inner wall of the second groove 31, and the second limit is configured to limit the distance that the driving member 13 moves downward, so that when the block 32 on the second component 3 is engaged by the locking member 11, when it is in this position, the wedge block can drive the locking member 11 to rotate when moving upward, and can also protect the elastic member.

[0063] The working principle of the interlocking structure 1 of this embodiment is:

[0064] If the first component 2 and the second component 3 are in a locked state, the locking shaft 1101 is stuck on the block 32, and the wedge 1301 is located at the lower part of the locking shaft 1101. When the first component 2 and the second component 3 need to be separated, the second component 3 is moved away, and the driving member 13 moves upward at the same time, and the wedge 1301 moves upward with the driving member 13. Since the upper surface of the wedge 1301 is an inclined surface, the wedge 1301 allows the locking shaft 1101 to rotate away from the first component 2, so that the block 32 is separated from the locking shaft 1101, and the first component 2 and the second component 3 are separated; when the locking shaft 1101 rotates away from the first component 2, the first elastic member 14 is compressed, and after the second component 3 and the first component 2 are separated, the external force on the locking shaft 1101 disappears, and due to the action of the first elastic member 14, the locking member 11 is driven to return to the initial state.

[0065] When the second component 3 needs to be stacked on the first component 2, the second component 3 moves downwardly toward the first component 2. When the lower surface of the wedge block 1301 contacts the locking shaft 1101, as the second component 3 continues to move downwardly toward the first component 2, the lower surface of the wedge block 1301 applies a force to the locking shaft 1101 to rotate in the direction away from the first component 2, until the lower surface of the second component 3 is completely in contact with the upper surface of the first component 2. Then, the downward movement of the second component 3 stops, and the force of the wedge block 1301 on the locking shaft 1101 disappears. When the locking shaft 1101 returns to its initial state due to the action of the first elastic member 14, the locking shaft 1101 is hooked on the clamping block 32, and the locking shaft 1101 tightly presses the clamping block 32 to fix the second component 3 and the first component 2.
