[0026] The following further elaborates in detail on a connection structure for stacking tool boxes proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description and claims, the advantages and features of the present invention will be clearer.

[0027] Refer to Figures 1 to 3 , the present application provides a connection structure for stacking tool boxes, including two tool box bodies stacked, and fixing parts and locking parts are provided on the outer side walls of the two tool box bodies, and unlocking components are provided on the lower surfaces of the two tool box bodies; the two tool box bodies are respectively an upper tool box body 1 and a lower tool box body 2 (the upper tool box body 1 is located above the lower tool box body), the fixing part on the upper tool box body 1 is an upper fixing part 3, the unlocking component on the upper tool box body 1 is an upper unlocking component, and the locking part on the lower tool box body 2 is a lower locking part;

[0028] Among them, a groove 4 is formed on the fixing part; the locking part includes a locking block 5 and an elastic component. The elastic component is arranged between the locking block 5 and the lower tool box body 2, and the locking block 5 is horizontally slid and connected to the lower tool box body 2;

[0029] The locking block 5 is clamped in the groove 4 to realize the fixed connection between the upper tool box body 1 and the lower tool box body 2; when there is a gap between the locking block 5 and the lower tool box body 2 after the locking block 5 moves, the upper unlocking component extends into the gap to realize the abutment against the locking block 5 and makes the locking block 5 disengage from the groove 4.

[0030] Further, two groups of fixing parts and locking parts are arranged on each tool box body, and the two groups of fixing parts and locking parts are located on the opposite sides of the tool box body, so that the connection between the upper tool box body 1 and the lower tool box body 2 is more stable. Of course, for each group of fixing parts and locking parts on each tool box body, the locking part is located above the pressing part. The unlocking components correspond to the fixing parts one by one, that is, the number of unlocking components is also two.

[0031] Further, since there are two groups of fixing parts and locking parts, the number of unlocking components is also two, corresponding to each group of fixing parts and locking parts one by one; among them, the two unlocking components are located between the two fixing parts of the corresponding tool box body.

[0032] Further, the fixing part and the tool box body are integrally formed.

[0033] In the implementation process of this solution, first place the upper tool box body 1 on the lower tool box body 2, press the upper tool box downward, so that the fixing part squeezes the locking block 5. Under the action of the elastic component, the locking block 5 is clamped in the groove 4; when unlocking, pull the locking block 5 outwards, at this time a gap is formed, and the unlocking component extends into the gap, so that the locking block 5 will not rebound under the action of the elastic component, that is, unlocking is realized. After the upper tool box body 1 is withdrawn from the lower tool box body 2, the unlocking component will leave from the gap, and the locking block 5 has no resistance. Under the action of the elastic component, the locking block 5 returns to its original position.

[0034] Next, the specific structure of the connection structure for stacking tool boxes in this embodiment will be further described. Among them, this solution takes the upper fixing part 3, the lower locking part and the upper unlocking component as examples for description. The fixing part on the lower tool box body 2 has the same structure as the upper fixing part 3, the unlocking component on the lower tool box body 2 is the same as the upper unlocking component, and the locking part on the upper tool box body 1 has the same structure as the lower locking part.

[0035] In this embodiment, accommodation grooves 6 are formed on the outer side walls of the tool box bodies, and the fixing parts and the locking parts are located in the corresponding accommodation grooves 6.

[0036] For further explanation, the accommodation groove 6 is actually formed by the inward depression of the tool box body during the molding process. After installing the corresponding pressing part and locking part, the appearance becomes more beautiful.

[0037] In this embodiment, the upper unlocking assembly includes an unlocking block 7, an unlocking spring 8 and a guide pin 9; the guide pin 9 is passed through the unlocking block 7 and arranged on the upper tool box body 1. The unlocking block 7 is slidably connected to the guide pin 9, and the unlocking spring 8 is located between the unlocking block 7 and the tool box body.

[0038] Furthermore, one end of the unlocking spring 8 is fixed to the lower surface of the upper tool box body 1, and the other end of the unlocking spring 8 is fixed to the unlocking block 7. Of course, the other end of the unlocking spring 8 can also abut against the unlocking block 7, and the unlocking spring 8 is passed through the guide pin 9. The guide pin 9 is vertically arranged, so that the unlocking block 7 slides along the vertical direction.

[0039] For further explanation, when the upper tool box body 1 is placed on the lower tool box body 2, the unlocking block 7 abuts against the locking block 5 and is compressed, that is, the unlocking block 7 moves upward on the guide pin 9; during the process of the locking block 5 being clamped into the groove 4 of the fixing part, that is, during the process of the locking block 5 moving outward and then contracting and tightly clamping the groove 4 under the action of the elastic component, the unlocking block 7 always abuts against the locking block 5 and is in a compressed state.

[0040] When the locking block 5 is pulled outward a certain distance to form a gap, the unlocking block 7 will be pushed downward under the action of the unlocking spring 8, so that the unlocking block 7 enters the gap, and finally the retraction of the locking block 5 is blocked, achieving the effect of facilitating unlocking.

[0041] In this embodiment, the guide pin 9 is threadedly connected to the upper tool box body 1, and a guide nut is threadedly connected to the guide pin 9. The guide nut abuts against the inner wall of the upper tool box for fixation.

[0042] Furthermore, the relative position of the guide pin 9 on the upper tool box body 1 can be adjusted, and thus the protruding distance of the locking block 5 can be adjusted.

[0043] In this embodiment, the lower locking part further includes a fixed seat 10 arranged on the lower tool box body 2. The locking block 5 is slidably connected to the fixed seat 10; wherein, the elastic component includes a connecting spring 11, one end of the connecting spring 11 is arranged on the locking block 5, the other end of the connecting spring 11 is arranged on the fixed seat 10, and the connecting spring 11 is horizontally arranged.

[0044] Further setting: There are two first T-shaped bars arranged in parallel and spaced apart in the receiving groove 6 of the locking part provided in the lower tool box body 2. Two first T-shaped grooves are provided on the lower bottom surface of the fixing seat 10. During installation, first place the first T-shaped bars in the first T-shaped grooves, and then move the fixing seat 10 to slide into the corresponding receiving groove 6. Since there are protrusions on the lower tool box body 2 located between the two first T-shaped bars, and a fixing groove is provided on the lower bottom surface of the fixing seat 10, and the protrusions are located in the fixing groove, the fixing seat 10 is fixed.

[0045] Further setting: There are two second T-shaped bars provided on the upper surface of the fixing seat 10. Corresponding two second T-shaped grooves are provided on the lower surface of the locking block 5, and the second T-shaped bars are located in the second T-shaped grooves, realizing the horizontal sliding of the locking block 5. In the natural state of the connecting spring 11, the connecting spring 11 pulls the locking block 5 close to the lower tool box body 2; when the locking block 5 is under the action of the fixing part, a moving phenomenon will occur.

[0046] In this embodiment, a first inclined surface 12 is provided on the fixing part, and the first inclined surface 12 is located below the groove 4; the locking block 5 includes a locking box body 19 and a buckle 13 provided on the locking box body 19, and a second inclined surface 18 is provided on the buckle 13. The first inclined surface 12 is used to contact the second inclined surface 18 and realize the buckling of the buckle 13 in the groove 4.

[0047] Further explanation: When the upper tool box body 1 moves downward to the lower tool box body 2, the first inclined surface 12 of the fixing part contacts the second inclined surface 18 of the buckle 13. Through the interaction of the first inclined surface 12 and the second inclined surface 18, the locking block 5 is pushed outwards, and then under the action of the connecting spring 11, the buckle 13 is buckled in the groove 4.

[0048] In this embodiment, there is an active chamber 14 in the locking box body 19 to prevent interference when the fixing part moves.

[0049] In this embodiment, an unlocking groove 15 is provided on the locking block 5, and the unlocking groove 15 is convenient for finger operation.

[0050] Further explanation: The unlocking groove 15 should be reasonably provided on the locking box body 19.
