Detailed Description

As shown in fig. 1, the utility model discloses a tool box 100, it includes upper housing 10, lower housing 20 and automatic hasp 30, and upper housing 10 and lower housing 20 accessible automatic hasp 30 are locked each other to make this tool box 100's locking and unblock simple operation, novel structure.

As shown in fig. 2 to 5, an upper concave portion 11 and an upper latch 12 located in the upper concave portion 11 are provided on an outer surface of the upper housing 10. The upper recess 11 can accommodate the automatic buckle 30 in the locked state of the tool box 100 and the shape of the upper recess 11 corresponds to the automatic buckle 30, so that the outer surface of the automatic buckle 30 is flush with the outer surface of the upper housing 10, and the tool box is more space-saving and beautiful. The upper recess 11 penetrates the upper case 10 upward so that the upper end of the automatic buckle 30 in the locked state is exposed to the outer surface of the upper case 10, and easy unlocking can be achieved by only lightly snapping the upper end of the automatic buckle 30 at the time of unlocking.

The upper latch 12 is engaged with the automatic buckle 30 in a locked state, thereby locking the tool box 100. The upper latch 12 is horizontally disposed, and a side surface (lower surface) of the upper latch 12 close to the lower housing 20 is a first inclined surface (not numbered), so that the upper latch 12 slides downwards into the automatic buckle 30 for locking, and the operation is convenient and fast, and the structure is simple.

As shown in fig. 6, the outer surface of the lower case 20 is provided with a recessed portion 21 and a receiving groove 22 extending downward from the recessed portion 21. When the upper case 10 and the lower case 20 are interlocked, the automatic buckle 30 is accommodated in the upper concave portion 11, the lower concave portion 21 and the accommodation groove 22; when the upper case 10 and the lower case 20 are unlocked, the automatic buckle 30 is accommodated in the lower recess 21 and the accommodation groove 22.

The automatic buckle 30 is rotatably provided in the lower recess 21, and the outer surface of the automatic buckle 30 is flush with the outer surface of the lower case 20. Meanwhile, the lower concave portion 21 and the upper concave portion 11 are aligned up and down and are penetrated to each other, so that the outer surface of the automatic buckle 30 is flush with the outer surfaces of the upper concave portion 11 and the lower concave portion 21 in the locked state. Circular holes 211 and second inclined surfaces 212 located above the circular holes 211 are formed on inner walls (not numbered) of both sides of the lower concave portion 21, and both sides of the automatic buckle 30 are rotatably connected in the two circular holes 211, so that the automatic buckle 30 rotates around the circular holes 211 of both sides. The second inclined surface 212 is provided to facilitate the automatic buckle 30 to slide down into the circular hole 211 when the automatic buckle 30 is mounted.

The housing groove 22 is defined by the outer wall portion 23 and the recessed portion 21, and the lower end of the automatic buckle 30 is disposed in the housing groove 22, so that the operation and rotation stroke of the lower end of the automatic buckle 30 are restricted, and the structure is simpler. Meanwhile, a plurality of partition walls 221 vertically connecting the lower recess 21 and the outer wall 23 are disposed in the accommodating groove 22, the partition walls 221 are disposed at intervals, and the partition walls 221 are mainly used for bearing the automatic buckle 30, so that the automatic buckle 30 is fixedly disposed on the partition walls 221, and a gap is formed between the lower end of the automatic buckle 30 and the bottom of the accommodating groove 22, thereby facilitating the rotation of the automatic buckle 30.

Referring to fig. 3, 5 and 7, the automatic buckle 30 includes a main body 31 and a lower tail 32 extending downward from the main body 31, and the main body 31 and the lower tail 32 are T-shaped. The thickness of the main body 31 is greater than that of the lower tail end 32, and the upper end of the main body 31 is an operating part 311, so that a finger can slightly open the operating part 311 in an outside direction away from the tool box 100 to unlock the tool box. The main body 31 has a lower latch 312 and a horizontal boss 313 located below the lower latch 312 on the inner side close to the tool box 100, and the lower latch 312 is disposed corresponding to the upper latch 12, so that the upper housing 10 and the lower housing 20 are locked by the engagement between the upper latch 12 and the lower latch 312. The horizontal projection 313 abuts on the outer surface of the depressed portion 21, and mainly serves to limit the rotational stroke of the automatic buckle 30. The left and right sides of the main body 31 near the lower tail end 32 are provided with a rotating shaft 314 inserted into the circular hole 211 of the lower housing 20, and the end of the rotating shaft 314 is provided with a third inclined surface 315 facing downward, so that the rotating shaft 314 can slide into the circular hole 211 through the second inclined surface 212 and the third inclined surface 315.

The lower end 32 is disposed in the receiving slot 22 such that the lower end 32 can only rotate in the receiving slot 22, thereby limiting the range of rotation of the automatic buckle 30. A positioning post 321 is disposed on a side of the lower end 32 close to the lower casing 20, and the positioning post 321 is used for sleeving a return spring (not shown), so that the return spring is located between the positioning post 321 and the lower casing 20. Preferably, in order to keep the position of the return spring relatively fixed, the lower tail end 32 may be accommodated between the two partition walls 221, and the return spring is disposed between the two partition walls 221, so that the position of the return spring is fixed and the return spring is not easy to leak.

Locking the upper case 10 with the lower case 20: the upper shell 10 is pressed downwards by hand, the upper latch 12 and the lower latch 312 are pressed against each other, the automatic hasp 30 rotates around the rotating shaft 314, and the reset spring is compressed under stress; when the upper latch 12 passes over the lower latch 312, the upper latch 12 slides into the lower portion of the lower latch 312, and at this time, the return spring releases the elastic force, the return spring returns to the original position in synchronization with the automatic buckle 30, the upper latch 12 and the lower latch 312 are engaged with each other, and the upper housing 10 and the lower housing 20 are locked with each other by the automatic buckle 30.

Unlocking the upper case 10 from the lower case 20: the operation part 311 is opened by hand in the direction away from the outer side of the tool box 100, the automatic buckle 30 rotates around the rotating shaft 314, and the return spring is compressed by force; after the lower latch 312 is removed from above the upper latch 12, at this time, the return spring releases the elastic force, the return spring and the automatic buckle 30 are reset synchronously, and at the same time, the upper housing 10 can be opened easily, and the upper housing 10 and the lower housing 20 are unlocked successfully.

The utility model discloses a tool box 100, which comprises an upper shell 10, a lower shell 20 and an automatic hasp 30 arranged on the lower shell 20, wherein when the upper shell 10 and the lower shell 20 are interlocked, the automatic hasp 30 is accommodated in an upper concave part 11, a lower concave part 21 and an accommodating groove 22; when the upper case 10 and the lower case 20 are unlocked, the upper end of the automatic buckle 30 may be pulled apart to the outside away from the tool box 100 to be unlocked. The tool box 100 locks the upper housing 10 and the lower housing 20 with each other through the automatic buckle 30, and meanwhile, when the upper housing 10 and the lower housing 20 are interlocked, the automatic buckle 30 can be completely accommodated in the concave part of the tool box 100, so that the tool box is convenient to operate and novel in structure.
