When the lock cylinder is in the unlocking position, the lock tongue slides to the first position to open the item , When the lock cylinder is in the locked position, the lock tongue slides to the second position to close the article. When the lock cylinder is in the tamper-proof position, the two ends of the latch can be locked inside the slot to fix the lock tongue The second position.

In another embodiment of the present invention, the housing has a housing cover, the housing cover is arranged at the other end of the lock cylinder away from the sliding space, the housing cover has a plurality of marks, and the plural marks can correspondingly indicate that the lock cylinder is at the unlocked position, the locked position, and One of the anti-pry positions.

In another embodiment of the present creation, the lock cylinder has an operating hole, which is provided at the other end of the lock cylinder away from the sliding space. The operating hole can be inserted into a key, and the key can control the rotation angle of the lock cylinder through the operating hole. The position of the control card.

In another embodiment of the present creation, the tongue has a groove, the groove is provided on the top surface of the tongue, the groove can be provided with an elastic member, and the two ends of the elastic member are pressed against the groove and the inner wall of the housing. In between, the elastic member makes the lock tongue normally located in the second position.

In another embodiment of the present invention, the card slot has a first contact surface and a second contact surface. The first contact surface is provided on a side of the card slot close to the top surface of the lock tongue, and the second contact surface Set on the other side of the card slot away from the top surface of the lock tongue. When the lock core is in the tamper-proof position, the two ends of the latch are completely pressed against the first abutting surface and the second abutting surface to make the lock The knob is stably locked in the card slot.

In another embodiment of the present invention, the lock tongue has a fixing part, and the fixing part is arranged at the other end of the lock tongue away from the groove. When the lock tongue is in the second position, the fixing part can be fixed on the article.

In another embodiment of the present invention, the card slot has an inclined surface, and the inclined surface is provided on one side of the second abutting surface. When the lock cylinder is rotated from the locking position to the tamper-proof position, the inclined surface enables the locking part to be smoothly locked.于卡槽。 In the card slot.

In another embodiment of the present creation, the latch is a long-shaped bump.

In another embodiment of the present invention, the length of the latch is smaller than the diameter of the lock cylinder.

In this way, when the lock core is in the anti-pry position in the present creation, the latching part can be completely locked in the slot, so that the lock tongue can be completely fixed in the second position without loosening. Compared with the conventional lock cylinder that can only be rotated to the locked position, the creative lock cylinder can be further rotated to the anti-prying position, and securely locked in the slot through the latch to achieve real anti-prying and anti-theft Function.

When the lock cylinder 20 is at the unlocking position P1, the lock tongue 30 slides to the first position S1 to unlock the article; when the lock cylinder 20 is at the locking position P2 and the tamper-proof position P3, the lock tongue 30 slides to the second position S2, Keep the item closed.

As shown in Figures 1 to 7, in this creative embodiment, the lock tongue 30 has a groove 32, an elastic member 33, and a securing portion 34, and the slot 31 has a first abutting surface 311, and a second contact surface 311. Two contact surfaces 312 and one inclined surface 313. The groove 32 is provided on the top surface of the lock tongue 30. The groove 32 can be provided with an elastic member 33. The two ends of the elastic member 33 are pressed between the groove 32 and the inner wall of the housing 10. Normally located at the second position S2; the locking portion 34 is provided at one end of the lock tongue 30 away from the groove 32. When the locking tongue 30 is in the second position S2, the locking portion 34 can be locked to one of the articles to be locked. Department (not shown in the figure). Among them, the elastic member 33 is a return spring, but it is not limited to this.

The first abutting surface 311 is provided on the side of the locking groove 31 close to the top surface of the bolt 30; the second abutting surface 312 is provided on the other side of the locking groove 31 away from the top surface of the locking tongue 30, the first of the locking portion 21 The end 211 can be completely pressed against the first abutting surface 311, and the second end 212 of the latching portion 21 may be fully pressed against the second abutting surface 312, so that the latching portion 21 can be firmly clamped in the slot 31 Inside; the inclined surface 313 is provided on one side of the second abutting surface 312, when the lock core 20 rotates from the locking position P2 to the tamper-proof position P3, the inclined surface 313 enables the latching portion 21 to be smoothly locked in the slot 31 to This complete card is secured to the card slot 31.

As shown in Figure 5 to Figure 7, and please refer to Figure 2 and Figure 3 at the same time, the following is an explanation of the actual operating state of this creation:

As shown in Figures 3 and 5, the latch 21 is pressed against the first abutting surface 311, the elastic member 33 is stretched, so that the lock cylinder 20 is normally located at the locking position P2, and the lock tongue 30 is normally It is located at the second position S2, so that the securing portion 34 is secured to the secured portion of the article to achieve the purpose of closing the article.

As shown in Figures 3 and 6, the user can insert the key into the operating hole 22 and rotate the lock cylinder 20 in a clockwise direction. The lock cylinder 20 rotates from the locked position P2 to the unlocked position P1, the second of the latch 21 The end 212 is pressed against the first abutting surface 311, the lock tongue 30 slides from the second position S2 to the first position S1, and compresses the elastic member 33, so that the clamping portion 34 is separated from the clamped portion, thereby opening the述物。 Said items. Wherein, when the lock cylinder 20 is at the unlocking position P1, the latch 21 is not stably locked in the card slot 31. Therefore, when the user pulls the key out of the operating hole 22, the elastic member 33 expands to make the lock cylinder 20 Returning from the unlocking position P1 to the locking position P2, and returning the lock tongue 30 from the first position S1 to the second position S2, so that the article can be closed normally in this creation.

As shown in Figures 3 and 7, the user can insert the key into the operating hole 22 to rotate the lock cylinder 20 in a counterclockwise direction. The lock cylinder 20 rotates from the locking position P2 to the tamper-proof position P3. One end 211 is pressed against the first abutting surface 311, the second end 212 of the latching portion 21 is pressed against the second abutting surface 312, and the latching portion 21 is completely clamped in the slot 31 to allow the lock tongue 30 It can be firmly locked in the second position S2 to prevent a person from inserting into the gap between the clamping portion 34 and the clamped portion, and the locking tongue 30 is pushed from the second position S2 to the first position S1 to achieve tamper resistance The purpose of opening.

In this way, when the lock core 20 is in the anti-pry position P3 in the present creation, the latching portion 21 can be completely locked in the slot 31, so that the lock tongue 30 can be firmly fixed in the second position S2 without loosening. Compared with the conventional lock cylinder 20 that can only be rotated to the locking position P2, the lock cylinder 20 of the present creation can be further rotated to the tamper-proof position P3, and is securely locked in the slot 31 through the latch 21 to achieve The real anti-theft function against prying open.
