Description

Technical Field

[0001] The utility model relates to the technical field of tool boxes, in particular to a locking structure of a tool box and the tool box. Background Art

[0002] Toolboxes are commonly used in daily life and are easy to carry. The box body and the box cover in the toolbox are generally locked by a buckle assembly. The buckle assembly in the prior art generally adopts a card table and a card slot matching method, that is, a card table is set on the box cover or the box body, and a rotatable cover plate is set on the box body or the box cover, and a card slot matching the card table is set on the cover plate. When the box body and the box cover are locked, the cover plate needs to be rotated, and the card slot is connected to the card table after the card slot is roughly aligned with the card table. At the same time, in order to ensure the connection strength between the box body and the box cover, the buckle assembly set is often too tight with the box body and the box cover.

[0003] There are deficiencies in the prior art: when the tool box falls, the buckle assembly and the box body and the box cover are too tightly matched, thereby causing damage to the buckle assembly and the tool box. Utility Model Content

[0004] The utility model aims to provide a locking structure of a tool box and a tool box, so as to solve the technical problem in the prior art that when the tool box falls, the buckle assembly and the tool box are damaged due to the over-tight fit between the buckle assembly and the box cover and the box body.

[0005] In order to solve the above-mentioned problem, the utility model provides a locking structure of a toolbox, the toolbox comprising: a box cover and a box body, the box cover is provided with a first groove, the box body is provided with a second groove, the first groove and the second groove extend along the same direction to accommodate the locking structure, and the box cover and the box body are detachably connected through the locking structure; wherein the locking structure comprises a connecting piece and a connecting rod, one end of the connecting rod is fixed to the second groove in a flippable manner, and the other end of the connecting rod is provided with an elastic part and is flip-connected to the connecting piece.

[0006] The present invention provides a locking structure for a tool box, which connects a box cover and a box body by setting a locking structure. When two tool boxes are stacked, the locking structure can not only connect the box cover and the box body, but also connect the two tool boxes at the same time; wherein, a connecting piece and a connecting rod are provided on the locking structure, and the function of the connecting piece is to connect the box cover and the box body or to connect two tool boxes. By connecting one end of the connecting rod to the second groove in a flippable manner, it is ensured that the connecting rod can be flipped 180 degrees, thereby enabling the connecting piece to move relative to the first groove and the second groove, thereby finally achieving the purpose of connection.

[0007] The present invention provides an elastic portion at the other end of the connecting rod. When the connecting piece is flipped relative to the connecting rod, the elastic portion can exert a certain resilience on the matching piece between the connecting piece and the connecting rod, thereby ensuring that the locking structure can conveniently lock the box cover under the action of the resilience force; in addition, when the tool boxes are stacked, on the one hand, the convenience of the side lock is increased, and on the other hand, when the two stacked tool boxes fall or encounter unexpected situations such as the two tool boxes falling, the two tool boxes are forcibly pulled apart so that the connecting piece can bounce open under the action of the elastic portion, thereby avoiding damage to the tool boxes caused by falling, thereby providing a certain protection for the tool boxes.

[0008] In some embodiments of the present application, the connecting rod includes a connecting rod pin and a first through hole, and the connecting rod pin passes through the first through hole and cooperates with the elastic portion.

[0009] By passing the connecting rod pin through the first through hole, the connecting rod pin and the elastic part are matched with each other. During the turning process of the connecting rod and the connecting piece, the connecting rod pin will intermittently abut or collide with the elastic part, which gives the connecting piece a certain resilience. When the locking structure is engaged with the first groove or the second groove, the installation part of the locking structure needs to be matched with the matching part of the first groove or the second groove. At this time, the operator needs to give the locking structure a force opposite to the elastic part, thereby ensuring the installation coordination of the locking structure.

[0010] In some embodiments of the present application, the distance between the inner wall on the side of the elastic part close to the connecting pin and the connecting pin is a first distance, and the distance between the inner wall on the side of the first through hole close to the elastic part and the connecting pin is a second distance, and the first distance is smaller than the second distance.

[0011] By setting the distance between the inner wall of the elastic part on the side close to the connecting pin and the connecting pin to be smaller than the distance between the inner wall of the first through hole on the side close to the elastic part and the connecting pin, the connecting pin can be prevented from being unable to abut against the elastic part due to the force of the inner wall of the first through hole, thereby realizing the rebound force applied by the elastic part to the connecting piece.

[0012] In some embodiments of the present application, a size of the first through-hole is larger than a circumferential cross-sectional size of the connecting rod pin.

[0013] By setting the size of the first through-hole larger than the circumferential cross-sectional size of the connecting pin, it is ensured that under the action of the elastic part, the connecting pin can be adjusted in the first through-hole, thereby increasing the adjustability of the connecting pin and facilitating the snapping of the locking structure.

[0014] In some embodiments of the present application, a fixing portion is provided inside the second groove, and the connecting rod further includes a rotating shaft and a second through hole, the second through hole is provided on a side of the connecting rod away from the first through hole, and the rotating shaft passes through the second through hole and the groove of the fixing portion in sequence.

[0015] A fixing portion is provided on the bottom wall of the second groove so that one end of the connecting rod is fixed to the box body, and the fixing portion is provided with a groove suitable for the rotation shaft to pass through; the connecting rod is also provided with a rotation shaft and a second through hole, and the second through hole is provided on the side of the connecting rod away from the first through hole, and the rotation shaft passes through the second through hole and the groove of the fixing portion in sequence, so as to ensure that the rotation shaft can rotate in the groove of the fixing portion, thereby making the connecting rod flip over as the rotation shaft rotates.

[0016] In some embodiments of the present application, a hollow groove is provided on one end of the first through hole close to the elastic part, and the circumferential cross-sectional dimension of the hollow groove is larger than the circumferential cross-sectional dimension of the elastic part; and / or the inner wall shape of the side of the elastic part close to the connecting pin is adapted to the outer wall shape of the connecting pin.

[0017] By setting a hollow groove at one end of the first perforation close to the elastic part, and making the circumferential cross-sectional size of the hollow groove larger than the circumferential cross-sectional size of the elastic part, it is ensured that the first perforation can accommodate the elastic part. When the connecting rod pin and the elastic part abut against each other, the connecting rod pin will exert a certain force on the elastic part, and the elastic part will stretch in the direction away from the connecting rod pin. At this time, the size of the first perforation is small, which will limit the stretching and rebound of the elastic part. Therefore, the hollow groove is set on the first perforation to provide a certain activity space for the elastic part.

[0018] By arranging the inner wall shape of the side of the elastic part close to the connecting rod pin to match the outer wall shape of the connecting rod pin, the wear of the connecting rod pin by the elastic part can be reduced during the turning process of the connecting rod, thereby increasing the service life of the elastic part and the connecting rod pin.

[0019] In some embodiments of the present application, when the locking structure is flipped in the direction of the first groove, the locking structure is engaged in the first groove and the second groove and protrudes relative to the length direction of the first groove; when the locking structure is flipped in the direction of the second groove, the locking structure is engaged in the first groove and the second groove.

[0020] When two tool boxes are stacked, the locking structure is flipped in the direction of the first groove. At this time, the locking structure is engaged in the first groove and the second groove and protrudes relative to the length direction of the first groove. This allows the locking structure to connect the box cover and the box body, and the protruding part of the locking structure is further connected to the bottom of the tool box above the box cover, thereby ensuring that at least two stacked tool boxes are fixed together. When the two tool boxes do not need to be connected, the locking structure is flipped in the direction of the second groove. At this time, the locking structure can connect the box cover and the box body at the same time. The locking structure is engaged in the first groove and the second groove and does not protrude outward, ensuring the overall beauty of the tool box.

[0021] In some embodiments of the present application, a first card slot is provided on the side wall of the first groove, a second card slot is provided on the side wall of the second groove, and bosses are provided on opposite sides of the locking structure; when the locking structure is flipped toward the direction of the first groove, the first card slot and the boss are interlocked; when the locking structure is flipped toward the direction of the second groove, the second card slot and the boss are interlocked.

[0022] When the locking structure is turned in the direction of the first groove, the first slot on the side wall of the first groove and the boss on the locking structure are interlocked, thereby realizing the connection between the two stacked tool boxes by the locking structure; when the locking structure is turned in the direction of the second groove, the second slot on the side wall of the second groove and the boss on the locking structure are interlocked, thereby realizing the connection between the cover and the body of the tool box by the locking structure. It should be noted that the two sides of the boss are inclined, thereby improving the convenience of the buckle locking operation of the locking structure.

[0023] In some embodiments of the present application, a first protrusion is provided on the side wall of the first groove, and a second protrusion is provided on the side wall of the second groove, and the first protrusion and the second protrusion abut against each other; a third protrusion is provided on the end of the second groove away from the first groove; a first limiting groove and a second limiting groove are provided on opposite sides of the locking structure; when the locking structure is flipped in the direction of the first groove, the first protrusion and the second protrusion cooperate with the second limiting groove, and the third protrusion cooperates with the first limiting groove; when the locking structure is flipped in the direction of the second groove, the first protrusion and the second protrusion cooperate with the first limiting groove.

[0024] When the locking structure is turned over in the direction of the first groove, the first protrusion on the side wall of the first groove and the second protrusion on the side wall of the second groove are simultaneously engaged with the second limiting groove on the locking structure, and the third protrusion on the side wall of the second groove is engaged with the first limiting groove on the locking structure, so that the locking structure connects the two stacked tool boxes; when the locking structure is turned over in the direction of the second groove, the first protrusion on the side wall of the first groove and the second protrusion on the side wall of the second groove are simultaneously engaged with the first limiting groove on the locking structure, so that the locking structure connects the cover of the tool box with the box body. This assembly method makes the locking buckle of the locking structure more convenient, and can realize the connection between the cover and the box body or the connection between two tool boxes.

[0025] The utility model further provides a tool box, on which the locking structure as described above is provided, so the tool box has the same beneficial effects as the locking structure as described above, which will not be described in detail here.

[0026] After adopting the technical solution of the utility model, the following technical effects can be achieved:

[0027] The present invention provides a locking structure for a toolbox, which connects a box cover and a box body by setting a locking structure. When two toolboxes are stacked, the locking structure can not only connect the box cover and the box body, but also connect the two toolboxes at the same time; wherein, a connecting piece and a connecting rod are provided on the locking structure, and the function of the connecting piece is to connect the box cover and the box body or to connect the two toolboxes. The present invention provides an elastic part at the other end of the connecting rod, and when the connecting piece is flipped relative to the connecting rod, the elastic part can apply a certain rebound force to the matching piece between the connecting piece and the connecting rod, thereby ensuring that the locking structure is convenient to lock the box cover under the action of the rebound force; in addition, when the toolboxes are stacked, on the one hand, the convenience of the side lock buckle is increased, and on the other hand, when the two stacked toolboxes fall or other unexpected situations occur, the two toolboxes are forcibly pulled apart so that the connecting piece can be bounced open under the action of the elastic part, thereby avoiding damage to the toolbox caused by falling, and providing a certain protection for the toolbox.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] An embodiment of the utility model provides a locking structure of a toolbox, the toolbox comprising: a box cover 100 and a box body 200, the box cover 100 is provided with a first groove 110, the box body 200 is provided with a second groove 210, the first groove 110 and the second groove 210 extend along the same direction to accommodate the locking structure 300, the box cover 100 and the box body 200 are detachably connected through the locking structure 300; wherein the locking structure 300 comprises a connecting piece 310 and a connecting rod 320, one end of the connecting rod 320 is fixed to the second groove 210 in a flippable manner, and the other end of the connecting rod 320 is provided with an elastic portion 321 and is flip-connected with the connecting piece 310.

[0038] like Figures 1 to 5 As shown, a toolbox provided by the present invention connects a box cover 100 and a box body 200 by setting a locking structure 300. When two toolboxes are stacked, the locking structure 300 can not only connect the box cover 100 and the box body 200, but also connect the two toolboxes at the same time; wherein, a connecting piece 310 and a connecting rod 320 are provided on the locking structure 300, and the function of the connecting piece 310 is to connect the box cover 100 and the box body 200 or to connect the two toolboxes, and by connecting one end of the connecting rod 320 to the second groove 210 in a flippable manner, it is ensured that the connecting rod 320 can be flipped 180 degrees, so that the connecting piece 310 can move relative to the first groove 110 and the second groove 210, and finally achieve the purpose of connection.

[0039] The present invention provides an elastic portion 321 at the other end of the connecting rod 320. When the connecting piece 310 is flipped relative to the connecting rod 320, the elastic portion 321 can apply a certain rebound force to the matching piece between the connecting piece 310 and the connecting rod 320, thereby ensuring that the locking structure 300 can easily lock the box cover 100 under the action of the rebound force; in addition, when the tool boxes are stacked, on the one hand, the convenience of the side lock is increased, and on the other hand, when the two stacked tool boxes fall or encounter unexpected situations such as the two tool boxes falling, the two tool boxes are forcibly pulled apart, so that the connecting piece 310 can be bounced open under the action of the elastic portion 321, thereby avoiding damage to the tool boxes caused by falling, thereby providing a certain protection for the tool boxes.

[0040] By designing the connecting rod 320 structure on the tool box, specifically, making the elastic part 321 that can rebound on the connecting rod 320, the connecting rod 320 structure combines rebound and rigidity. When the locking structure 300 is engaged with the first groove 110 or the second groove 210, the locking structure 300 has a dead point due to the elastic part 321, which will make it difficult to buckle the locking structure 300. However, when the tool box falls, the connection between the tool boxes is pulled apart due to the setting of the elastic part 321, which reduces the possibility of damage to the tool box due to falling.

[0041] In some embodiments of the present application, the connecting rod 320 includes a connecting rod pin 322 and a first through hole 323 . The connecting rod pin 322 passes through the first through hole 323 and cooperates with the elastic portion 321 .

[0042] like Figure 5 As shown, by passing the connecting rod pin 322 through the first through hole 323, the connecting rod pin 322 and the elastic part 321 are matched with each other. During the turning process of the connecting rod 320 and the connecting member 310, the connecting rod pin 322 will intermittently abut or collide with the elastic part 321, which gives a certain resilience to the connecting member 310. When the locking structure 300 is engaged with the first groove 110 or the second groove 210, the mounting part of the locking structure 300 needs to be matched with the matching part of the first groove 110 or the second groove 210. At this time, the operator needs to give the locking structure 300 a force opposite to the elastic part 321, thereby ensuring the installation and coordination of the locking structure 300.

[0043] In some embodiments of the present application, the distance between the inner wall of the elastic portion 321 on the side close to the connecting pin 322 and the connecting pin 322 is a first distance, and the distance between the inner wall of the first through hole 323 on the side close to the elastic portion 321 and the connecting pin 322 is a second distance, and the first distance is smaller than the second distance.

[0044] like Figure 5 As shown, by setting the distance between the inner wall of the elastic part 321 on the side close to the connecting pin 322 and the connecting pin 322 to be smaller than the distance between the inner wall of the first through hole 323 on the side close to the elastic part 321 and the connecting pin 322, it is avoided that the connecting pin 322 cannot abut against the elastic part 321 due to the force of the inner wall of the first through hole 323, thereby realizing the rebound force exerted by the elastic part 321 on the connecting member 310.

[0045] In some embodiments of the present application, the size of the first through hole 323 is larger than the circumferential cross-sectional size of the connecting rod pin 322 .

[0046] like Figure 5As shown, by setting the size of the first through hole 323 to be larger than the circumferential cross-sectional size of the connecting pin 322, it is ensured that under the action of the elastic portion 321, the connecting pin 322 can be adjusted in the first through hole 323, thereby increasing the adjustability of the connecting pin 322, and thus facilitating the buckling of the locking structure 300. Specifically, the minimum diameter of the first through hole 323 is larger than the maximum diameter of the connecting pin 322.

[0047] In some embodiments of the present application, a fixing portion 214 is provided inside the second groove 210, and the connecting rod 320 also includes a rotating shaft 324 and a second through hole 325. The second through hole 325 is provided on a side of the connecting rod 320 away from the first through hole 323, and the rotating shaft 324 passes through the second through hole 325 and the groove of the fixing portion 214 in sequence.

[0048] like Figures 3 to 5 As shown, by setting a fixing portion 214 on the bottom wall of the second groove 210, one end of the connecting rod 320 is fixed on the box body 200, and the fixing portion 214 is provided with a groove suitable for the rotation shaft 324 to pass through; the connecting rod 320 is also provided with a rotation shaft 324 and a second through hole 325, by setting the second through hole 325 on the side of the connecting rod 320 away from the first through hole 323, and passing the rotation shaft 324 through the second through hole 325 and the groove of the fixing portion 214 in sequence, so as to ensure that the rotation shaft 324 can rotate in the groove of the fixing portion 214, so that the connecting rod 320 is turned over with the rotation of the rotation shaft 324. For example, the fixing portion 214 is provided with a hook plate, and the rotation shaft 324 is installed in the groove of the hook plate, so as to facilitate the turning of the connecting rod 320 with the rotation of the rotation shaft 324; further, two hooks are provided closely above the hook plate, and the hooks are used to improve the firmness and stability of the hook plate.

[0049] In some embodiments of the present application, a hollow groove 326 is provided on one end of the first through hole 323 close to the elastic part 321, and the circumferential cross-sectional dimension of the hollow groove 326 is larger than the circumferential cross-sectional dimension of the elastic part 321; and / or the inner wall shape of the side of the elastic part 321 close to the connecting pin 322 is adapted to the outer wall shape of the connecting pin 322.

[0050] like Figure 5As shown, a hollow groove 326 is provided on one end of the first through hole 323 close to the elastic part 321, and the circumferential cross-sectional dimension of the hollow groove 326 is larger than the circumferential cross-sectional dimension of the elastic part 321, thereby ensuring that the first through hole 323 can accommodate the elastic part 321. When the connecting rod pin 322 and the elastic part 321 abut against each other, the connecting rod pin 322 will exert a certain effect on the elastic part 321, and the elastic part 321 will stretch in the direction away from the connecting rod pin 322. At this time, the size of the first through hole 323 is small, which will limit the stretching and rebound of the elastic part 321. Therefore, the hollow groove 326 is provided on the first through hole 323, so as to provide a certain activity space for the elastic part 321.

[0051] By setting the inner wall shape of the side of the elastic part 321 close to the connecting rod pin 322 to be compatible with the outer wall shape of the connecting rod pin 322, the wear of the elastic part 321 on the connecting rod pin 322 can be reduced during the turning process of the connecting rod 320, thereby increasing the service life of the elastic part 321 and the connecting rod pin 322. Preferably, the connecting rod pin 322 is cylindrical.

[0052] In some embodiments of the present application, when the locking structure 300 is flipped in the direction of the first groove 110, the locking structure 300 is engaged in the first groove 110 and the second groove 210 and protrudes relative to the length direction of the first groove 110; when the locking structure 300 is flipped in the direction of the second groove 210, the locking structure 300 is engaged in the first groove 110 and the second groove 210.

[0053] like Figure 6 As shown, when two tool boxes are stacked, the locking structure 300 is turned in the direction of the first groove 110. At this time, the locking structure 300 is engaged in the first groove 110 and the second groove 210 and protrudes relative to the length direction of the first groove 110. This allows the locking structure 300 to connect the box cover 100 and the box body 200 at the same time. The protruding part of the locking structure 300 is further connected to the bottom of the tool box above the box cover 100, thereby ensuring that at least two stacked tool boxes are fixed together. When it is not necessary to connect the two tool boxes, the locking structure 300 is turned in the direction of the second groove 210. At this time, the locking structure 300 can connect the box cover 100 and the box body 200 at the same time. The locking structure 300 is engaged in the first groove 110 and the second groove 210 and does not protrude outward, ensuring the overall beauty of the tool box.

[0054] In some embodiments of the present application, a first card slot 111 is provided on the side wall of the first groove 110, a second card slot 211 is provided on the side wall of the second groove 210, and bosses are provided on opposite sides of the locking structure 300; when the locking structure 300 is flipped in the direction of the first groove 110, the first card slot 111 and the boss are interlocked with each other; when the locking structure 300 is flipped in the direction of the second groove 210, the second card slot 211 and the boss are interlocked with each other.

[0055] like Figure 6 As shown, when the locking structure 300 is turned in the direction of the first groove 110, the first slot 111 on the side wall of the first groove 110 and the boss on the locking structure 300 are mutually engaged, thereby realizing the connection between the locking structure 300 and the two stacked tool boxes; when the locking structure 300 is turned in the direction of the second groove 210, the second slot 211 on the side wall of the second groove 210 and the boss on the locking structure 300 are mutually engaged, thereby realizing the connection between the locking structure 300 and the box cover 100 and the box body 200 of the tool box. It should be noted that the two sides of the boss are inclined, thereby improving the convenience of the locking structure 300 in the buckle locking operation; in addition, the two sides of the boss are also provided with a convex structure with a lower height than the boss, which facilitates the boss to engage with the first groove 110 or the second groove 210 when the locking structure 300 slides in the first groove 110 or the second groove 210.

[0056] In some embodiments of the present application, a first protrusion 112 is provided on the side wall of the first groove 110, and a second protrusion 212 is provided on the side wall of the second groove 210, and the first protrusion 112 and the second protrusion 212 abut against each other; a third protrusion 213 is provided on the end of the second groove 210 away from the first groove 110; a first limiting groove 330 and a second limiting groove 340 are provided on opposite sides of the locking structure 300; when the locking structure 300 is flipped in the direction of the first groove 110, the first protrusion 112 and the second protrusion 212 cooperate with the second limiting groove 340, and the third protrusion 213 cooperates with the first limiting groove 330; when the locking structure 300 is flipped in the direction of the second groove 210, the first protrusion 112 and the second protrusion 212 cooperate with the first limiting groove 330.

[0057] like Figure 6As shown, when the locking structure 300 is turned over in the direction of the first groove 110, the first protrusion 112 on the side wall of the first groove 110 and the second protrusion 212 on the side wall of the second groove 210 are simultaneously engaged with the second limiting groove 340 on the locking structure 300, and the third protrusion 213 on the side wall of the second groove 210 is engaged with the first limiting groove 330 on the locking structure 300, so as to realize the connection of the locking structure 300 to the two stacked tool boxes; when the locking structure 300 is turned over in the direction of the second groove 210, the first protrusion 112 on the side wall of the first groove 110 and the second protrusion 212 on the side wall of the second groove 210 are simultaneously engaged with the first limiting groove 330 on the locking structure 300, so as to realize the connection of the box cover 100 and the box body 200 of the tool box by the locking structure 300. This assembly method makes the locking buckle of the locking structure 300 more convenient, and can realize the connection between the box cover 100 and the box body 200 or the connection between two tool boxes.

[0058] The embodiment of the utility model further provides a tool box, on which the locking structure 300 as described above is provided, so the tool box has the same beneficial effects as the locking structure 300 described above, which will not be described in detail here.

[0059] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
