The embodiment of the drawing of this case is illustrated by taking the base 10 as an accessory independent of the door panel as an example, but this case is not limited thereto. In other embodiments, the base body 10 of the lock can also be the door panel itself.

In some embodiments, the base 10 is a cubic structure, the first surface 11 is opposite to the second surface 12, and the direction vertically connecting the first surface 11 and the second surface 12 is the first direction D1, and the direction perpendicular to the first direction D1 is the second direction. Direction D2.

The lock hole 13 is opened on the first surface 11 for the key 30 to be inserted into the base 10 to drive the latch 20 to shift to change the locked/released state of the lock and the object M. In some embodiments, the lock hole 13 is extended from the first surface 11 along the first direction D1.

In some embodiments, the inner groove 14 is open to the second surface 12 but not to the first surface 11 . In these embodiments, the inner groove 14 has an inner groove wall 141, the inner groove wall 141 is parallel to the first surface 11 and the second surface 12, and the inner groove wall 141 is connected to the lock hole 13 and is located in the second direction with the lock hole 13 at different positions on D2. From the perspective of FIG. 4 , in the second direction D2 , the position of the locking hole 13 relative to the inner groove wall 141 is upward, and vice versa, the position of the inner groove wall 141 relative to the locking hole 13 is downward.

In some embodiments, the installation groove 15 is open to the second surface 12 but not to the first surface 11 . In these embodiments, the positions of the installation groove 15 and the inner groove 14 partially overlap in the second direction D2 , and the non-overlapping portion of the installation groove 15 and the inner groove 14 has a wall 151 of the installation groove. The installation groove wall 151 is parallel to the first surface 11 , the second surface 12 and the inner groove wall 141 , and the installation groove wall 151 is connected to the inner groove 14 and is located below the inner groove 14 in the second direction D2 .

In some embodiments, the base 10 has a side 17 , and the side 17 is vertically connected to the first surface 11 and the second surface 12 . The side opening 16 opens to the side surface 17 of the base body 10 and communicates with the installation groove 15 . In these embodiments, when the lock is mated with the object M, 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 20 is a sheet structure, and the outer contour of the latch 20 corresponds to the shape of the fixing part M1 of the object M and the shape of the installation groove 15, so that the latch 20 is accommodated in the installation groove 15 Afterwards, it can be displaced in the installation groove 15, and can be displaced along the installation groove 15 to the side opening 16 and the fixing part M1. In these embodiments, when the latch member 20 is accommodated in the installation groove 15 , a part of the latch member 20 corresponds to the position of the inner groove 14 , and the rest of the latch member leans against the wall 151 of the installation groove.

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 part 20 extends into the fixed part M1 through the side opening 16 to lock the object M, or the latch part extending into the fixed part M1 20 moves out of the fixing part M1 to release the object M.

Based on the foregoing, 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 to the lock hole 13, a special key 30 must be used to access the latch from the lock hole 13 through the inner groove 14. Part 20, generally a conventional key cannot touch the latch part 20, so it has a higher level of anti-theft.

In some embodiments, the present 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 drive, and the through hole 21 of the latch 20 is in the second direction D2. The location is within the confines of the inner tank 14 .

The key 30 includes a rod 31 and a pivot 32 . The rod body 31 extends along the axial direction X and has an outer peripheral surface 311 . The outer peripheral surface 311 has a circular profile. One end of the pivot member 32 is pivotably disposed on the rod body 31 so as to pivot around a first radial direction Y1 , and the first radial direction Y1 is perpendicular to the axis X. The other end of the pivot member 32 has a toggle portion 323, and the toggle 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 FIG. 3 ), and the cross section of the toggle portion 323 The shape corresponds to the shape of the through hole 21 of the latch 20 .

In some embodiments, the rod body 31 has a groove 312 , the groove 312 is recessed by 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 33 extends along the first radial direction Y1 , so that the pivot member 32 can rotate around the first radial direction Y1 through the pivot 33 .

In some embodiments, the pivot member 32 includes a pivot portion 321 , a connecting section 322 and a toggle portion 323 connected in sequence. The connecting section 322 is a long rectangular cube, and the pivot part 321 and the toggle part 323 are engaged on the same surface of the connecting section 322 adjacent to the two ends. The outer contour of the pivot part 321 is arc-shaped, and the toggle part 323 is 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 , and 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 accommodated in the groove 312 , and the pivot 33 passes through the pivot portion 321 to be pivotally arranged between the two first groove sides 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 as the pivot member 32 pivots. to the outside of the groove 312. In these embodiments, the end point of the pivoting stroke of the pivot member 32 is viewed from the position of the toggle portion 323 , and the end point of the stroke when the pivot member 32 pivots until the toggle portion 323 is located in the groove 312 is that the toggle portion 323 abuts against The position of the groove bottom surface 3121 of the groove 312 ; and the position where the connecting section 322 abuts against one of the second groove side surfaces 3123 is the position where the pivot member 32 pivots to the stroke end of the toggle portion 323 outside the groove 312 . In these embodiments, the pivoting angle range of the pivot member 32 is 90 degrees, but this application is not limited thereto.

The instructions for using the key 30 in these embodiments in conjunction with the lock are as follows.

First, when the object M is to be locked with a lock. Referring to FIG. 1 to FIG. 4 , firstly, the lock and the object M to be locked are matched to the side opening 16 of the base 10 where the fixing portion M1 of the object M communicates. Next, the key 30 is inserted into the lock hole 13 of the lock with the axis X of the rod body 31 parallel to the first direction D1 of the lock and the pivot 32 is located above. After the key 30 is inserted into the lock hole 13, refer to Fig. 5 to Fig. 7, and then turn the key 30, so that the rod body 31 of the key 30 is rotated to the position where the pivot 32 is located below. When the position is changed to the lower position, the pivot 32 is affected by gravity and naturally takes the pivot 33 as the rotation axis to go around the first radial direction Y1, escape from the groove 312 of the rod body 31 and at the same time be accommodated in the inner groove 14 below the lock hole 13 . In this state, the pivoting part 32 pivots 90 degrees, so the toggle part 323 becomes a state extending along the axial direction X with the pivoting of the pivoting part 32, and the position of the toggle part 323 in the second direction D2 corresponds to The position of the through hole 21 of the latch 20 .

Next, referring to FIGS. 8 to 10 , the key 30 is inserted along the first direction D1 of the base 10 of the lock 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 perforation 21 of the latch 20, the key 30 is turned again, as shown in FIG. The part 20 is displaced toward the side opening 16 and the fixing part M1 of the object M. When the latch part 20 is displaced into the fixing part M1 through the side opening 16, the object M is locked by the latch part 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 in a direction away from the second surface 12 along the first direction D1 of the base 10 of the lock. Perforation 21. Continue to pull the key 30 away until the pivot 32 of the key 30 touches the connection between the inner groove wall 141 and the lock hole 13. In this state, the pivot 32 of the key 30 contacts the inner groove wall 141 and the lock hole with the connecting section 322 13, the key 30 continues to move away from the second surface 12, and the pivot 32 is pushed to pivot. The pivot of the pivot 32 is to drive the toggle part 323 to pivot toward the groove bottom 3121 and make the key 32 pivot. The pivot piece 32 as a whole is gradually accommodated in the groove 312. After the pivot piece 32 is fully accommodated in the groove 312, the key 30 can also be moved out of the lock through the lock hole 13 synchronously, thereby completing the locking of the lockset and the object M and The key 30 is taken out.

When wanting to use the key 30 to unlock the locked lockset and the object M, the method of inserting the key 30 is the same as that described above. After inserting the key 30, turn the key 30 to make the pivot 32 pivot to the bottom, and then continue to rotate to the bottom of the pivot 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 a direction close to the second surface 12 along the first direction D1, so that the toggle portion 323 of the pivot 32 is inserted into the latch 20 After being inserted into the hole 21, the key 30 is turned to drive the latch 20 protruding into the fixing portion M1 to disengage 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, the key 30 is directly pulled out along the first direction D1 toward a direction away from the second surface 12 , and the key 30 can be taken out and the lock and the object M are unlocked.

It can be seen from the above that the operation method of the key 30 in this case is different from that of ordinary conventional keys. Even if the key 30 is stolen, the lock cannot be unlocked through general unlocking methods; The duplication can be completed by setting different tooth shapes on it. The key duplicating machine used in general lock shops cannot duplicate the key 30 of this case, so the duplication of the key 30 of this case is difficult, and the anti-theft level can be improved.

In some embodiments, in order to improve the certainty and convenience when the key 30 cooperates with the lock, the lock hole 13 includes a connected first portion 131 and a second portion 132 , and the key 30 further includes a stopper 34 . The stopper 34 includes a ring portion 341 and a convex rib 342. The ring portion 341 is an annular body and includes opposite inner peripheral surfaces and outer peripheral surfaces. The shape of the inner peripheral surface of the ring portion 341 corresponds to the shape of the rod body 31. The surface shape corresponds to the shape of the first portion 131 of the locking hole 13 , and the shape of the protruding rib 342 corresponds to the shape of the second portion 132 of the locking hole 13 , and the protruding rib 342 is disposed above the outer periphery of the ring portion 341 .

In these embodiments, the shape of the rod body 31 and the first part 131 of the locking hole 13 are both circular, and the ring portion 341 of the stopper 34 is fixedly sleeved outside the rod body 31, and the convex rib 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 where the axis X of the rod body 31 is parallel to the first direction D1 of the lock, and the pivot member 32 is located above the rod body 31 , the rib 342 of the stopper 34 is located on the rod body 31 The position below.

Thereby, when the key 30 is inserted into the lock hole 13 of the lock with the pivot member 32 at the upper position, since the rib 342 of the stopper 34 is located below the rod body 31, the lock hole 13 corresponding to the shape of the 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 lockhole 13. When the key 30 is inserted into the lockhole 13, the stopper of the key 30 The rib 342 of the key 34 will be stopped on the first surface 11 to limit the depth of the key 30 inserted into the lock hole 13. In this state, the position of the pivot member 32 in the first direction D1 can just correspond to the position of the key 30 in the inner groove 14. The position ensures 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 axial direction X of the key 30, the distance between the rib 342 of the stopper 34 and the pivot 321 of the pivot 32 is greater than the distance between the first surface 11 of the base 10 and the inner groove wall 141 in the first direction. The distance on D1 ensures that when the stopper 34 of the key 30 stops against 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 installation groove wall 151 is greater than the distance in the axial direction X of the groove bottom surface 3121 of the groove 312 of the key 30 . In this way, the operator only needs to ensure that the position of the pivot 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 . It can ensure that the pivot member 32 has enough space to pivot 90 degrees to a position corresponding to the latch member 20 .

In some embodiments, in order to improve the operation convenience of the key 30, when the pivot 32 of the key 30 is located above the rod body 31, and the toggle part 323 of the key 30 abuts against the groove bottom surface 3121 of the groove 312, the pivot The connecting section 322 of 32 protrudes from the outer peripheral surface 311 of the rod body 31 . The first portion 131 of the locking hole 13 of the base body 10 includes a first segment 1311 , a second segment 1312 and a third segment 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 aperture H1 must be sufficient for the ring portion 341 of the stopper 34 of the key 30 to pass through, the second aperture H2 must be sufficient for the hub 32 of the key 30 to pass through, and the third aperture H3 must be sufficient. For the rod body 31 of the key 30 to pass through. 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, and the second section 1312 is respectively connected to the first section 1311 and the third section 1313 eccentric.

Thereby, when the key 30 stretches into the lockhole 13 and wants to turn, since the key 30 is first inserted into the lockhole 13 by 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 lockhole 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 locking hole 13 . Here, due to the eccentric shape of the second section 1312 of the first portion 131 of the lock hole 13 , the pivot member 32 can only be limited to one-way rotation. In this way, when the key 30 has to be rotated to the second part 132 corresponding to the upper position of the lock hole 13 from the rib 342 of the stopper 34 at the lower position, the second section 1312 of the first part 131 of the lock hole 13 The eccentric stop makes the rotation direction of the key 30 restricted, and its rotation angle is also limited to 180 degrees, providing the operator with more clear operation guidelines and avoiding possible operations caused by the unrestricted rotation direction of the operator. Doubtful situations occur.

In some embodiments, in order to provide the uniqueness of the lock, the shape of the through hole 21 of the latch part 20 of each lock can be designed to be different, so that the dial of the key 30 corresponding to the through hole 21 of the latch part 20 of each lock The shape of the moving part 323 is also different. In this way, each lock has its unique key 30 and latch 20, which improves the anti-theft performance. It is worth noting that since the latch 20 is arranged in the installation groove 15 of the base 10 and is not exposed on the first surface 11 or the lock hole 13, the appearance of the base 10 is completely inconclusive. The shape of the perforation 21 prevents criminals from imitating the shape of the key 30 driving the latch 20 from the appearance of the base body 10, thereby improving the anti-theft level.

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

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

In some embodiments, the key 30 further includes two detachable grips 35, the two grips 35 are semi-arc-shaped respectively, and the two grips 35 are respectively detachably arranged on both sides of the head 313, and When the two holding parts 35 are disposed on the head 313 , the two holding parts 35 form a circular shape. In these embodiments, the annular shape formed by the two grips 35 is shaped around the axial direction X of the key 30, whereby the annular shape of the head 313 of the rod body 31 of the key 30 and the two grips 35 form a The ring shape becomes an orthogonal shape, which not only can provide the operator with hand-held operation, but also improves the aesthetics of the key 30 .
