The side opening 16 is open to the side surface 17 of the base body 10 and communicates with the mounting groove 15 . In these embodiments, when the lock and the object M are aligned, the position of the side opening 16 corresponds to the position of the fixing portion M1 and can communicate with each other.

In some embodiments, the latch member 20 has a sheet structure, and the outer contour of the latch member 20 corresponds to the shape of the fixing part M1 of the object M and the mounting groove 15, so that the latch member 20 is accommodated in the mounting groove 15. Then it can be displaced in the mounting groove 15 and can be displaced along the mounting groove 15 to the side opening 16 and the fixed part M1. In these embodiments, when the latch 20 is received in the installation groove 15 , part of the latch 20 corresponds to the position of the inner groove 14 , and the remaining part abuts against the installation groove wall 151 .

Thereby, when the base body 10 of the lock moves to the installation groove 15 and communicates with the fixed part M1, the movable latch 20 extends into the fixed part M1 through the side opening 16 to lock the object M, or the latch 20 extends into the fixed part M1. 20 Remove the fixing part M1 to release the object M.

Based on the above, since the latch 20 is disposed between the first surface 11 and the second surface 12 of the base 10 and is not directly exposed in the keyhole 13, a special key 30 must be used to access the latch from the keyhole 13 through the inner groove 14. Part 20. Generally, a conventional key cannot access the latch part 20, so it has a high anti-theft level.

In some embodiments, this case provides a key 30 suitable for the aforementioned lock. In these embodiments, the latch 20 has a through hole 21 for the key 30 to cooperate with, and the through hole 21 of the latch 20 is in the second direction D2. The position is within the range of the inner groove 14.

The key 30 includes a lever 31 and a pivot 32 . The rod body 31 extends along the axial direction X and has an outer peripheral surface 311, and the outer peripheral surface 311 has a circular outline. One end of the pivot member 32 is pivotably disposed on the rod body 31 and can pivot around the first radial direction Y1, which is perpendicular to the axial direction X. The other end of the pivot member 32 has a dialing portion 323. The dialing portion 323 extends along the second radial direction Y2 perpendicular to the axial direction X and the first radial direction Y1 (in the state of Figure 3), and the cross section of the dialing portion 323 The shape corresponds to the shape of the aperture 21 of the latch 20 .

In some embodiments, the rod body 31 has a groove 312 , the groove 312 is recessed from the outer peripheral surface 311 , and the pivot member 32 is pivotably disposed in the groove 312 through the pivot shaft 33 . In these embodiments, the connecting direction of the two ends of the pivot shaft 33 extends along the first radial direction Y1, thereby allowing the pivot member 32 to rotate around the first radial direction Y1 through the pivot shaft 33.

In some embodiments, the pivot member 32 includes a pivot portion 321, a connecting section 322 and a dialing portion 323 connected in sequence. The connecting section 322 is a long rectangular cube, and the pivot part 321 and the dialing part 323 are connected on the same surface of the connecting section 322 at positions adjacent to the two ends. The outer contour of the pivot portion 321 is arc-shaped, and the dialing portion 323 has a cylindrical structure.

In these embodiments, the groove 312 of the rod body 31 is a rectangular groove and includes a groove bottom surface 3121, two first groove side surfaces 3122, and two second groove side surfaces 3123. The two first groove side surfaces 3122 are opposite to each other and connected to the groove bottom surface 3121. The two second groove side surfaces 3123 are opposite to each other and connected to the groove bottom surface 3121 and the two first groove side surfaces 3122. The pivot portion 321 of the pivot member 32 is received in the groove 312, and passes through the pivot portion 321 through the pivot shaft 33 to be pivoted between the two first groove side surfaces 3122 of the groove 312.

Since the toggle portion 323 and the pivot portion 321 are located on the same surface of the connecting section 322, when the pivot member 32 pivots, the toggle portion 323 can be accommodated in the groove 312 or displaced along with the pivot of the pivot member 32. to the outside of groove 312. In these embodiments, the end point of the pivot stroke of the pivot member 32 is viewed from the position of the dial portion 323. The end point of the pivot stroke of the pivot member 32 when the pivot member 32 pivots to the dial portion 323 located in the groove 312 is when the dial portion 323 abuts against the groove 312. The position of the groove bottom surface 3121 of the groove 312; and the end point of the stroke when the pivot member 32 pivots to the toggle portion 323 located outside the groove 312 is the position where the connecting section 322 abuts one of the second groove side surfaces 3123. In these embodiments, the pivot angle range of the pivot member 32 is 90 degrees, but the present case is not limited to this.

The use of the key 30 in these embodiments with the lock is described below.

First, when the lock is to be used to lock the object M. Referring to FIGS. 1 to 4 , first, the lock and the object M to be locked are aligned to the fixing portion M1 of the object M connected to the side opening 16 of the base body 10 . Then, insert the key 30 into the lock hole 13 of the lock in an orientation such that the axial direction X of the rod body 31 is parallel to the first direction D1 of the lock and the pivot 32 is located upward. After the key 30 is inserted into the lock hole 13, refer to Figures 5 to 7, and then turn the key 30 so that the rod 31 of the key 30 rotates to the position where the pivot 32 is located below. During the process of turning the key 30, the pivot 32 moves from above. The position changes to the lower position. Under the influence of gravity, the pivot member 32 naturally takes the pivot axis 33 as the axis of rotation and escapes from the groove 312 of the rod body 31 around the first radial direction Y1 and is simultaneously accommodated in the inner groove 14 located below the lock hole 13 . . In this state, the pivot 32 pivots 90 degrees, so the dialing portion 323 extends along the axial direction X along with the pivoting of the pivot 32 , and the position of the dialing portion 323 in the second direction D2 corresponds to Location of hole 21 for latch 20 .

Next, referring to FIGS. 8 to 10 , the key 30 is extended along the first direction D1 of the lock base 10 toward the second surface 12 until the toggle portion 323 of the key 30 is inserted into the through hole 21 of the latch 20 . After the toggle part 323 of the key 30 is inserted into the through hole 21 of the latch 20, the key 30 is turned again. As shown in FIG. 11, the pivot 32 and the toggle part 323 of the key 30 can drive the latch as the key 30 moves. The component 20 is displaced toward the side opening 16 and the fixing part M1 of the object M. When the latch component 20 is displaced into the fixing part M1 through the side opening 16, the object M is locked by the latch component 20 of the lock.

Next, referring to FIGS. 12 to 14 , after the lock and the object M are locked by the latch 20 , the key 30 is pulled away from the latch 20 along the first direction D1 of the base 10 of the lock in a direction away from the second surface 12 . Piercing 21. Continue to pull out the key 30 until the pivot member 32 of the key 30 contacts the connection between the inner groove wall 141 and the lock hole 13. In this state, the pivot member 32 of the key 30 contacts the inner groove wall 141 and the lock hole 13 with the connecting section 322. 13, the key 30 continues to move away from the second surface 12, and the pivot member 32 is pushed to pivot. The pivot of the pivot member 32 drives the toggle portion 323 to pivot toward the bottom surface 3121 of the groove and causes the key 30 to pivot. The entire pivot member 32 is gradually received into the groove 312. After the entire pivot member 32 is received into the groove 312, the key 30 can also be synchronously moved out of the lock through the lock hole 13, thereby completing the locking of the lock and the object M. Key 30 is taken out.

When you want to use the key 30 to unlock the locked lock and object M, the method of inserting the key 30 is the same as mentioned above. After inserting the key 30, turn the key 30 to make the pivot member 32 pivot downward, and then continue to rotate to the bottom of the pivot member 32. The toggle portion 323 corresponds to the position of the through hole 21 of the latch 20 , and then the key 30 is moved in the first direction D1 toward the second surface 12 so that the toggle portion 323 of the pivot 32 is inserted into the latch 20 After inserting through the hole 21, the key 30 is turned to drive the latch 20 extending into the fixing portion M1 to separate from the fixing portion M1 of the object M, thereby unlocking the lock and the object M. After the lock and the object M are unlocked, directly pull the key 30 away from the second surface 12 along the first direction D1 to remove the key 30 and complete the unlocking of the lock and the object M.

From the foregoing, it can be seen that the operation method of the key 30 in this case is different from that of a conventional key. Even if the key 30 is stolen, the lock cannot be unlocked through ordinary unlocking techniques. In addition, since the structure of the key 30 in this case is different from that of a conventional key, it is also different in appearance. The key 30 in this case can be copied by setting different tooth shapes on it. Key duplicating machines used in general lock shops cannot copy the key 30 in this case. Therefore, the key 30 in this case is difficult to copy and can further improve the anti-theft level.

In some embodiments, in order to improve the certainty and convenience when the key 30 is operated with the lock, the lock hole 13 includes a first part 131 and a second part 132 that are connected, and the key 30 further includes a stopper 34 . The stopper 34 includes a ring portion 341 and a rib 342. The ring portion 341 is an annular body and includes an inner circumferential surface and an outer circumferential surface that are opposite to each other. The shape of the inner circumferential surface of the ring portion 341 corresponds to the shape of the rod body 31. The outer circumference of the ring portion 341 The surface shape corresponds to the shape of the first part 131 of the keyhole 13 , and the shape of the protruding rib 342 corresponds to the shape of the second part 132 of the keyhole 13 , and the protruding rib 342 is disposed above the outer circumference of the ring part 341 .

In these embodiments, the shape of the rod body 31 and the first part 131 of the lock hole 13 are both circular, and the ring portion 341 of the stopper 34 is fixedly sleeved on the outside of the rod body 31 , and the ribs of the stopper 34 342 and the pivot member 32 are located on opposite sides of the rod body 31 . That is to say, when the key 30 is in an orientation in which the axial direction The direction below.

Therefore, when the key 30 is inserted into the lock hole 13 of the lock with the pivot member 32 located upward, since the protruding rib 342 of the stopper 34 is located below the rod body 31, the lock hole 13 corresponding to the shape of the protruding rib 342 The second part 132 is located above the first part 131. Therefore, the shape of the stopper 34 of the key 30 does not completely correspond to the shape of the keyhole 13. When the key 30 is inserted into the keyhole 13, the stopper of the key 30 The protruding ribs 342 of 34 will be blocked by the first surface 11, limiting the depth of the key 30 inserted into the lock hole 13. In this state, the position of the pivot 32 in the first direction D1 can exactly correspond to the position of the key 30 in the inner groove 14. position to ensure that after the key 30 is inserted into the base body 10, there is enough space in the base body 10 for the pivot member 32 to pivot.

In these embodiments, in the axis direction The distance on D1 ensures that when the stopper 34 of the key 30 stops on the first surface 11, the position of the pivot portion 321 of the pivot member 32 has crossed the inner groove wall 141 and entered the range of the inner groove 14.

In addition, the distance in the first direction D1 between the inner groove wall 141 of the base body 10 and the mounting groove wall 151 is greater than the distance in the axial direction X between the groove bottom surface 3121 of the groove 312 of the key 30 . Therefore, the operator only needs to ensure that the position of the pivot member 32 is above the key 30 and insert the key 30 into the lock hole 13 until the stopper 34 abuts against the first surface 11. In this state, the key 30 can be pivoted. It is ensured that the pivot member 32 has enough space to pivot 90 degrees to the position corresponding to the latch member 20 .

In some embodiments, in order to improve the convenience of operating the key 30 , when the pivot member 32 of the key 30 is located above the rod body 31 and the toggle portion 323 of the key 30 is against the bottom surface 3121 of the groove 312 , the pivot member The connecting section 322 of 32 protrudes from the outer peripheral surface 311 of the rod body 31 . The first part 131 of the keyhole 13 of the base 10 includes a first section 1311, a second section 1312 and a third section 1313 extending along the first direction D1 and connected in sequence. The first section 1311 is open to the first surface 11 and has a first aperture H1, the second section 1312 has a second aperture H2, and the third section 1313 is open to the second surface 12 and has a third aperture H3.

In these embodiments, the first hole H1 needs to be enough for the ring portion 341 of the stopper 34 of the key 30 to pass, the second hole H2 needs to be enough for the pivot 32 of the key 30 to pass, and the third hole H3 needs to be enough For the rod body 31 of the key 30 to pass. Therefore, the first aperture H1 is larger than the second aperture H2 and the third aperture H3, and the second aperture H2 is larger than the third aperture H3. In addition, the first section 1311, the second section 1312 and the third section 1313 are circular holes respectively, and the first section 1311 and the third section 1313 are concentric, while the second section 1312 is respectively connected with the first section 1311 and the third section 1313. eccentric.

Therefore, when the key 30 is extended into the lock hole 13 and is about to be rotated, since the key 30 is first inserted into the lock hole 13 from the front end of the rod body 31 , the front end of the rod body 31 of the key 30 will pass through the first part 131 of the lock hole 13 The first section 1311 and the second section 1312 are inserted into the third section 1313 , and the pivot member 32 is located in the second section 1312 of the first part 131 of the keyhole 13 . Here, due to the eccentric shape of the second section 1312 of the first part 131 of the lock hole 13, the pivot member 32 can only rotate in one direction. In this way, when the key 30 is rotated from the lower position of the stopper 34 to the second part 132 corresponding to the upper position of the lock hole 13, the second section 1312 of the first part 131 of the lock hole 13 The eccentric stop limits the rotation direction of the key 30 and its rotation angle is also limited to 180 degrees, providing the operator with clearer operating guidance and avoiding possible operations that may occur due to the unrestricted rotation direction. A suspicious situation occurs.

In some embodiments, in order to provide the uniqueness of the lock, the shape of the through hole 21 of the latch member 20 of each lock may be designed to be different. In this way, the key 30 corresponding to the through hole 21 of the latch member 20 of each lock may be moved. The shape of the moving part 323 is also different. In this way, each lock has a unique key 30 and latch 20, thereby improving the anti-theft performance. It is worth noting that since the latch 20 is disposed in the installation groove 15 of the base 10 and is not exposed on the first surface 11 or the keyhole 13 , it is completely impossible to know from the appearance of the base 10 what is used to drive the latch 20 . Due to the shape of the perforation 21, criminals cannot imitate the shape of the key 30 that drives the latch 20 based on the appearance of the base 10, thereby improving the anti-theft level.

In some embodiments, to ensure the stability of the latch 20, the lock further includes a limiting member 40. One end of the limiting member 40 is threaded and the other end is a cylinder. The latch 20 has a long groove 22 , and the extending direction of the long groove 22 is parallel to the extending direction of the mounting groove 15 . In these embodiments, one end of the limiting member 40 is fixed in the mounting groove 15 with a thread, and the long slot 22 of the latch member 20 is sleeved on the cylinder at the other end of the limiting member 40 . Thereby, when the latch member 20 is accommodated in the installation slot 15, it can be surely displaced along the installation slot 15 through the guidance of the limiting member 40 and the long slot 22, and the stability of the overall structure can be improved at the same time.

In some embodiments, in order to facilitate the operator to hold the key 30, the rod 31 of the key 30 has a head 313. The head 313 is an annular structure formed around the first radial direction Y1, thereby allowing the user to operate the key 30. It can be held on the head 313 for easy operation. In addition, it can also be combined with a hand strap or a key ring on the ring-shaped head 313 for easy carrying. It is worth noting that the shape of the head 313 of the rod body 31 of the key 30 in this case is not limited to this.

In some embodiments, the key 30 further includes two detachable holding parts 35. The two holding parts 35 are each in a semi-circular arc shape. The two holding parts 35 are detachably provided on both sides of the head 313, and When the two holding parts 35 are disposed on the head 313, the pair of two holding parts 35 form a circular ring shape. In these embodiments, the annular shape formed by the two holding parts 35 is formed around the axial direction The circular shape becomes an orthogonal shape, which not only provides the operator with hand-held operation, but also improves the aesthetics of the key 30 .

Although the present disclosure has been disclosed in some embodiments, this is not intended to limit the present disclosure.
