Description

Technical Field

[0001] The utility model belongs to the technical field of tool boxes, and in particular relates to a tool box combination with multiple stacking modes. Background Art

[0002] At present, the existing technology has a single stacking method for toolboxes. One method is vertical stacking or horizontal connection between boxes of the same size. The other method is to set a limiter in the horizontal direction to connect the upper and lower boxes when stacking up and down. This connection method requires that the bottom dimensions of the stacked boxes are consistent, and it is not necessary for the height dimensions of the boxes to be consistent. However, the existing boxes are of different sizes. When the bottom dimensions of the two boxes are different, it is impossible to combine the two boxes. When two parallel boxes are placed on a large box, there is no connection between the two boxes on the top. During the movement, they are easy to detach from the large box on the bottom, which is not conducive to transportation. In other words, the combination method that can be achieved by the toolbox structure in the existing technology is not convenient enough in actual use. Utility Model Content

[0053] A first tool box 1 and a second tool box 2 form a fourth combination, the rotating connecting piece 4 rotates to be parallel to the top surface of the first tool box 1, the second tool box 2 is arranged on the top surface of the first tool box 1 along the length direction of the first tool box 1, and the connection between the second tool box 2 and the first tool box 1 is achieved by two limiting components 5 on the first tool box 1; the fourth combination can be used alone, or the second tool box 2 or the third tool box 3 can be combined above the second tool box 2 of the fourth combination, and any other number of first tool boxes 2 can be combined below the first tool box 2 of the second combination.

[0054] A first tool box 1 and a third tool box 3 form a fifth combination, the rotating connector 4 rotates to a state parallel to the top surface of the first tool box 1, the third tool box 3 is arranged on the top surface of the first tool box 1 along the length direction of the first tool box 1, and the connection between the third tool box 3 and the first tool box 1 is achieved by two limit assemblies 5 on the first tool box 1; the fifth combination can be used alone, or the second tool box 2 or the third tool box 3 can be combined above the third tool box 3 of the fifth combination, and any other number of first tool boxes 2 can be combined below the first tool box 2 of the fifth combination.

[0055] In order to further realize the connection between the toolboxes, the present embodiment further includes a plurality of first limit clamps 7 matched with the limit assembly 5, a plurality of second limit clamps 8 matched with the rotating connector 4, and a plurality of third limit clamps 9 matched with the second limit clamps 8. The first limit clamps 7 are arranged on both sides of the bottom surface width direction of the first toolbox 1, one side of the bottom surface length direction of the second toolbox 2, and one side of the bottom surface length direction of the third toolbox 3; the second limit clamps 8 are arranged on the other side of the bottom surface length direction of the second toolbox 2 and the other side of the bottom surface length direction of the third toolbox 3; the third limit clamps 9 are arranged on the side of the top surface of the second toolbox 2 away from the limit assembly 5 and the side of the top surface of the third toolbox 3 away from the limit assembly 5.

[0056] The above-mentioned rotating connector 4 includes a rotating connector body 10. On both sides of one end of the rotating connector body 10, outwardly extending portions form first clamping ends 11. The first clamping ends 11 cooperate with the clamping grooves 6 to enable the rotating connector 4 to rotate within the clamping grooves 6 with the length direction of the clamping grooves 6 as the rotation center. Preferably, an installation portion 21 that cooperates with the first clamping ends 11 is provided in the clamping grooves 6. The two ends of the first clamping ends 11 are cylindrical. The first clamping ends 11 are clamped within the installation portion 21 of the clamping grooves 6. The installation portion 21 positions the first clamping ends 11 and simultaneously realizes the connection between the rotating connector 4 and the first toolbox 1. On both sides of the other end of the rotating connector body 10, outwardly extending portions form second clamping ends 12. The two ends of the second clamping ends 12 cooperate with the second limiting clamping members 8 on the two second toolboxes 2, or cooperate with the second limiting clamping members 8 on the two third toolboxes 3, or cooperate with the second limiting clamping member 8 on one second toolbox 2 and the second limiting clamping member 8 on one third toolbox 3. The rotating connector body 10 rotates within the clamping grooves 6 with the first clamping ends 11 as the rotation axis, so as to realize the switching of the rotating connector body 10 between a state parallel to the top surface of the first toolbox 1 and a state perpendicular to the top surface of the first toolbox 1. When the rotating connector body 10 is in a state parallel to the top surface of the first toolbox 1, the rotating connector body 10 rotates to be completely within the clamping grooves 6. At this time, the rotating connector body 10 is completely hidden within the first toolbox 1. When the rotating connector body 10 is in a state perpendicular to the top surface of the first toolbox 1, the rotating connector body 10 exposes from the clamping grooves 6, facilitating the connection of the second clamping ends 12 of the rotating connector body 10 with other toolboxes.

[0057] The above-mentioned limiting assembly 5 includes a limiting platform 13 and a pushing and pulling member 14. In the middle of the limiting platform 13, a groove for installing the pushing and pulling member 14 is formed. At least two groups of limiting groove groups 16 are provided at the bottom of the groove on the limiting platform 13. On one side of the pushing and pulling member 14, a part is cut off to form a first clamping portion 17 with a U-shaped cross-section. The first clamping portion 17 cooperates with the first limiting clamping member 7. An elastic clamping member 18 is provided at the bottom of the pushing and pulling member 14. The elastic clamping member 18 can cooperate with any of the limiting groove groups 16. By adjusting which limiting groove group 16 the elastic clamping member 18 cooperates with, the position adjustment of the pushing and pulling member 14 on the limiting platform 13 is realized.

[0058] Specifically, the inwardly extending portion at the top of the limiting platform 5 forms a groove edge 22, so that the pushing and pulling member 14 is limited on the limiting platform 5. The two sides of the bottom surface of the limiting platform 5 are set in a stepped shape, and the two ends of the pushing and pulling member 14 are in a stepped shape. The stepped structure of the pushing and pulling member 14 cooperates with the stepped structure of the limiting platform 5 to realize the structural connection between the limiting platform 5 and the pushing and pulling member 14.

[0059] In order to prevent the push-pull member 14 from completely escaping from the limiting platform 5 during movement, two blocking blocks 23 are provided on the limiting platform 5 to limit the farthest outward movement of the push-pull member 14 and ensure that the push-pull member 14 will not completely escaping from the limiting platform 5.

[0060] In order to prevent the relative position between the push-pull member 14 and the limiting platform 13 from being offset during adjustment, the present embodiment further includes at least one guide block 15 and at least one mounting groove 19. Preferably, two guide blocks 15 are provided, and the two guide blocks 15 are distributed on both sides of the limiting groove group 16. The guide block 15 is provided inside the limiting platform 13 along the width direction of the limiting platform 13. The setting direction of the guide block 15 is the moving direction of the push-pull member 14. The mounting groove 19 is provided on the push-pull member 14. The mounting groove 19 cooperates with the guide block 15 to realize the connection between the push-pull member 14 and the limiting platform 13, and provides guidance for the movement of the push-pull member 14, thereby ensuring that the moving direction of the push-pull member 14 is always in the required direction without lateral offset.

[0061] The elastic clamp 18 is in an L-shaped structure, the longer side of the elastic clamp 18 is parallel to the limiting platform 13, and at least one protrusion 20 is provided at the bottom of the longer side of the elastic clamp 18. The limiting groove group 16 has two limiting grooves, and the two limiting grooves match the protrusions 20 on the elastic clamp 18. When the push-pull member 14 moves to the point where the protrusion 20 on the elastic clamp 18 is in a limiting groove in a limiting groove group 16 away from the blocking block 23, the relative position between the push-pull member 14 and the limiting platform 13 is limited. When two protrusions 20 are provided, when the push-pull member 14 moves to the point where the two protrusions 20 on the elastic clamp 18 are in two limiting grooves in a limiting groove group 16 at the same time, the relative position between the push-pull member 14 and the limiting platform 13 is limited. Preferably, the limiting groove near the blocking block 23 in each limiting groove group 16 is inclined to the other limiting groove, so as to facilitate the protrusion 20 to pass through the limiting groove better. Because the elastic clip 18 has a certain elasticity, when it is necessary to adjust the push-pull member 14 to cooperate with another set of limit groove groups 16, the push-pull member 14 can be pushed hard to make the push-pull member 14 disengage from the current limit groove group 16 and then move to cooperate with the next set of limit groove groups 16.

[0062] In addition, the first toolbox 1 of this embodiment can be prepared in various sizes, and the minimum length dimension of the bottom surface of the first toolbox 1 is required to be the sum of the width dimensions of the second toolbox 2 and the third toolbox 3; there is no requirement for the height dimension of the first toolbox 1. When several first toolboxes 1 are stacked together, it is sufficient that the top dimension of the first toolbox 1 at the bottom is always greater than or equal to the bottom dimension of the first toolbox 1 at the top, and there is no requirement for the height dimension. Figure 5As shown, two first tool boxes 1 of different sizes can be stacked under the first assembly. Even if the bottom surface sizes of the two tool boxes are different, it is only necessary to change the size of the limiting platform 13 and set more groups of limiting grooves 16 to meet the requirement that the limiting assembly 5 can connect the lower and upper tool boxes together.

[0063] The fourth and fifth combinations mentioned above, because the bottom size of the toolbox at the top is smaller than the bottom size of the toolbox at the bottom, both combinations are achieved by setting a plurality of limit slot groups 16 in the limit platform 13, and pushing the push-pull member 14 to the limit slot group 16 at the appropriate position to achieve the assembly of the fourth and fifth combinations. That is, in this application, the limit platform 13 on the first toolbox 1 is designed to be the maximum size that can be achieved, that is, the maximum number of limit slot groups 16 that can be designed, which can be matched with the connection between multiple toolboxes with the number matching the number of limit slot groups 16. It can be seen that this embodiment has wide applicability and diverse combinations, and can meet various market needs. And the design of the limit assembly 5 not only meets the matching between toolboxes of the same size, but also meets the connection between toolboxes of various sizes.
