[0037] Example 1

[0038] like Figures 1-4 As shown, this embodiment provides a stacking tool box 100, including a box body 110, a box cover 120 and a fastener 130; a hook 111 is provided on the left and right sides of the bottom of the box body 110 respectively. The box cover 120 is arranged on the box body 110, and a mounting groove 121 is provided on each of the left and right side surfaces thereof. The top surface of the mounting groove 121 is provided with an opening 1211, and the opening 1211 passes through the top surface of the box cover 120; the fastener 130 is slidably installed in the mounting groove 121, and the top surface of the fastener 130 does not exceed the opening 1211, which can reduce the wear of the fastener 130 during daily use; the fastener 130 includes a accommodating cavity 131 with a slot 132, and the accommodating cavity 131 is connected to the opening 1211 for accommodating the hook 111 of another stacking toolbox 100; by sliding the fastener 130 back and forth, the slot 132 can be engaged with or disengaged from the hook 111 of another stacking toolbox 100.

[0039] When multiple stacking toolboxes 100 need to be stacked up and down, first confirm that the latch 130 of the stacking toolbox 100 below is in the first position; then, vertically align the stacking toolbox 100 above with the stacking toolbox 100 below to stack them, so that the hook 111 of the stacking toolbox 100 above falls into the accommodating cavity 131 of the latch 130 of the stacking toolbox 100 below; finally, move the latch 130 of the stacking toolbox 100 below to the second position, so that the hook 111 of the stacking toolbox 100 above moves into the accommodating cavity 131 of the latch 130 of the stacking toolbox 100 to complete the engagement with the slot 132.

[0040] Please review Figure 1 In this embodiment, the inner bottom surface of the mounting slot 121 is provided with a first groove 1212 for limiting the latch 130 to be in the first position; and a second groove 1213 for limiting the latch 130 to be in the second position. Figure 2 An elastic member 133 is provided on the positioning working surface 130a where the latch 130 abuts against the inner bottom surface of the mounting groove 121. One end of the elastic member 133 extends downward to form a convex portion 1331, and the shape of the convex portion 1331 matches the first groove 1212 and the second groove 1213.

[0041] Please refer to Figure 5 and Figure 6 When the latch 130 is moved from the first position to the second position, a backward thrust is applied to the latch 130, causing the elastic member 133 to deform under the thrust, causing the protrusion 1331 to disengage from the first groove 1212. After a certain distance of displacement, the protrusion 1331 engages with the second groove 1213 and is restrained in the second position. At this time, the hook 111 of the stacking tool box 100 located above is fully engaged with the slot 132. Conversely, when the latch 130 is moved from the second position to the first position, the protrusion 1331 moves forward to disengage from the second groove 1213 and engage with the first groove 1212, being restrained in the first position, causing the hook 111 of the stacking tool box 100 located above to disengage from the slot 132.

[0042] It should be noted that in this embodiment, the hook opening of the hook 111 faces forward and the first position is forward of the second position, so a backward thrust is applied to the latch 130. In other embodiments, when the hook opening of the hook 111 faces backward and the first position is backward of the second position, a forward thrust is required to be applied to the latch 130.

[0043] like Figure 1-Figure 3 As shown, in order to prevent the clamping member 130 from being excessively moved due to excessive force or excessive movement of the clamping member 130, causing the clamping slot 132 to excessively squeeze the clamping hook 111, thereby causing the clamping hook 111 to break unexpectedly or affecting the service life of the clamping hook 111, a step structure 137 can be provided on each of the left and right sides of the upper end surface of the clamping member 130. The step structure 137 can cooperate with the opening 1211 to limit the sliding distance of the clamping member 130 (see FIG. Figure 5 and Figure 6 ).

[0044] In addition, in order to prevent the latch 130 from being excessively pressed against the hook 111 by the latch 131 due to excessive force applied to the latch 130 or excessive movement, thereby causing the hook 111 to break unexpectedly or affecting its service life, a first protrusion 1214 and a second protrusion 1215 may be further provided on the inner bottom surface of the mounting groove 121. Accordingly, a limiting groove 134 is provided at each of the front and rear ends of the positioning working surface 130a. The first protrusion 1214 is provided on the side of the first groove 1212 facing away from the second groove 1213 (the front side in this embodiment); and the second protrusion 1215 is provided on the side of the second groove 1213 facing away from the first groove 1212 (the rear side in this embodiment). When the latch 130 is moved from the first position to the second position, the limiting groove 134 on the rear side abuts against the front end face of the second protrusion 1215 to achieve limiting; when the latch 130 is moved from the second position to the first position, the limiting groove 134 on the front side abuts against the rear end face of the first protrusion 1214 to achieve limiting.

[0045] Furthermore, if Figure 3 As shown, in order to facilitate the installation of the fastener 130 in the installation groove 121 and to facilitate the movement of the fastener 130 in the installation groove 121, an operating portion 135 can be provided on the fastener 130, and the operating portion 135 is provided on the side or top surface of the fastener 130 exposed from the installation groove 121. The operating portion 135 can be a square groove as shown in the figure, or a circular groove or other shape required by the design, or a square protrusion or a circular protrusion, so as to facilitate the operator to perform the installation and movement operations manually.

[0046] Furthermore, if Figure 3 As shown, in order to facilitate the operator to know the operating direction of the fastener 130, a direction indication icon 136 can be set on the fastener 130. The direction indication icon 136 can be set on the side or top surface of the fastener 130 where the installation slot 121 is exposed.

[0047] Furthermore, a reinforcing rib 1111 is provided between the hook 111 and the side surface of the box body 110 . The provision of the reinforcing rib 1111 can enhance the structural strength of the hook 111 and reduce the probability of breakage due to accidental collision after being engaged with the fastener 130 .

[0048] Example 2

[0049] like Figure 7As shown, this embodiment provides a stacking toolbox 200. This differs from the first embodiment in that two hooks 211 are provided on the left and right sides of the bottom of the box body 210. Accordingly, the latch 230 includes two accommodating cavities 231 with slots 232, each capable of engaging with the two corresponding hooks 211. In other embodiments, the number of hooks 211 and accommodating cavities 231 can be greater than two. This design can achieve multiple points of engagement on the same side, further improving the connection strength between the upper and lower stacking toolboxes 200.

[0050] Example 3

[0051] like Figure 8 and Figure 9 As shown, this embodiment provides a stacking toolbox 300, which differs from the second embodiment in the sliding retaining method of the latch 330. In this embodiment, a sliding guide rail 340 is fixedly mounted below the mounting slot 321. A guide block 341 and an elastic member 342 are provided on the upper end surface of the sliding guide rail 340. The guide block 341 is arranged in a front-to-back direction to guide the sliding direction of the latch 330. One end of the elastic member 342 extends upward to form a protrusion 3421, which is arranged perpendicular to the arrangement direction of the guide block 341. The guide block 341 and the protrusion 3421 are exposed on the inner bottom surface of the mounting slot 321.

[0052] Correspondingly, if Figure 10 As shown, the positioning working surface 330a of the latch 330 abutting against the inner bottom surface of the mounting groove 321 is provided with a guide groove 333 that cooperates with the guide block 341, and a first positioning groove 334 and a second positioning groove 335 that match the shape of the protrusion 3421. The first positioning groove 334 locates the first position, and the second positioning groove 335 locates the second position.

[0053] In this embodiment, when it is necessary to lock the upper and lower stacking toolboxes 300, the latch 330 is moved from the first position to the second position, and a forward thrust is applied to the latch 330, causing the elastic member 133 to deform under the thrust, causing the protrusion 3421 to disengage from the first positioning groove 334. After moving a certain distance, the protrusion 3421 engages with the second positioning groove 335 and is restrained in the second position. At this time, the hook 311 of the upper stacking toolbox 300 is fully engaged with the slot 332. Conversely, when the latch 330 is moved from the second position to the first position, the protrusion 3421 moves backward to disengage from the second positioning groove 335 and engage with the first positioning groove 334, being restrained in the first position, causing the hook 311 of the upper stacking toolbox 300 to disengage from the slot 332.
