Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-4 A sharp weapon box with a self-locking function includes a box body 12, a card plate 13 is installed inside the box body 12, and a plurality of card slots 1 are opened at the top of the card plate 13, positioning holes 14 are opened on both sides of the top ends of the box body 12, and a pull plate 11 is arranged above both sides of the positioning holes 14, and a cross bar 19 is installed on both sides of one side of the pull plate 11, and one end of the cross bar 19 passes through one side of the box body 12 and is connected to a lock plate 15, and the lock plate 15 is connected to a second spring by welding at the middle position near one side of the box body 12 Block 20, and one end of the second spring block 20 is connected to one side of the inside of the box body 12 by welding, a box cover 4 is arranged above the box body 12, and vertical rods 9 are installed on both sides of the top of the inside of the box cover 4, and both sides of the bottom of the vertical rod 9 are hinged with deflection plates 18 through hinges, and the outer side of the vertical rod 9 is sleeved with a movable sleeve 2, the top of the movable sleeve 2 is connected to the first spring block 3 by welding, and both sides of the movable sleeve 2 are hinged with connecting rods 16 through hinges, and positioning rods 17 are installed on both sides of both ends of the bottom of the box cover 4;

[0021] The positioning rod 17 is arranged just above the positioning hole 14, and the bottom end of the positioning rod 17 passes through the top end of the positioning hole 14 and extends into the interior of the positioning hole 14;

[0022] The first spring block 3 is sleeved on the outside of the vertical rod 9, and the top of the first spring block 3 is connected to the top of the inner part of the box cover 4 by welding;

[0023] The connecting rod 16 and the deflection plate 18 are both in an inclined state, and the bottom end of the connecting rod 16 is hinged to one end of the deflection plate 18 through a hinge;

[0024] The lock plate 15 is C-shaped, and the bottom end of the vertical rod 9 passes through the top end of the lock plate 15 and extends to the bottom of the lock plate 15, and the bottom end of the lock plate 15 is in contact with the top end of the deflection plate 18;

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the use of the device, firstly, the device can put the sharp weapon into the box body 12 by providing the card plate 13, and insert it into the card slot 1 to keep it stable, and then by covering the box cover 4, due to the presence of the positioning hole 14 and the positioning rod 17, a positioning effect can be achieved to prevent the deviation phenomenon, and then in the process of the box cover 4 covering the box body 12, due to the presence of the movable sleeve 2, the vertical rod 9 can pass through the interior of the lock plate 15, which will squeeze the deflection plate 18, causing the deflection plate 18 to rotate, so that the connecting rod 16 pushes the movable sleeve 2 to move upward, thereby squeezing the first spring block 3, so that the first spring block 3 is in a compressed state, until Until the deflection plate 18 passes through the interior of the lock plate 15 as a whole, the elastic reset action of the first spring block 3 makes the two deflection plates 18 open, so that the deflection plate 18 can be stably stuck above the lock plate 15 and remain stable, thereby realizing the self-locking function of the device. The operation is simple, and only needs to cover the box cover 4 and press it, which effectively avoids the phenomenon of forgetting to lock, and is relatively convenient. Finally, when the device needs to be unlocked, it is only necessary to pull the pull plate 11. During the movement of the pull plate 11, the lock plate 15 can be driven to move horizontally by the cross bar 19 to release the restriction on the deflection plate 18. At this time, the box cover 4 can be taken out as a whole, and the pull plate 11 can be released. The lock plate 15 can be reset under the elastic action of the second spring block 20.

[0026] Embodiment 2: A baffle 10 is provided below the box cover 4, and a rotating knob 6 is provided at the top of the box cover 4, the bottom end of the rotating knob 6 passes through the top of the box cover 4 and is connected to a threaded rod 7, and a threaded block 5 is sleeved on the outer side of the threaded rod 7, and both sides of the threaded block 5 are connected to fixed rods 8 by welding;

[0027] The fixing rod 8 is L-shaped, and the bottom end of the fixing rod 8 is connected to the top end of the baffle 10 by welding;

[0028] The baffle 10 is arranged just above the card slot 1, and two ends of the baffle 10 are in contact with two ends inside the box body 12;

[0029] Specifically, Figure 1 and Figure 3As shown, in order to further increase the practicality of the device and improve the stability of the device, after the box cover 4 is closed and self-locked, the user can also rotate the rotating knob 6, and the rotation of the rotating knob 6 can drive the threaded rod 7 to rotate, and the rotation of the threaded rod 7 can make the threaded block 5 rotate. Since the threaded block 5 is connected to the baffle 10 through the fixing rod 8, under the restriction of the baffle 10 received in the box body 12, the threaded block 5 can only move up and down on the outside of the threaded rod 7, so that the baffle 10 can be driven up and down by the fixing rod 8 to adjust the height position of the baffle 10, and the baffle 10 can be pressed just above the sharp weapon, which has a limiting effect on the sharp weapon inserted above the card slot 1, thereby increasing the stability of the device and facilitating the transfer of the device.
