Description

Lock core and its lock

The present invention relates to a lock core and a lock thereof, and in particular to a lock core and a lock thereof which are easy to assemble and can maintain the integrity and refinement of the product.

As shown in [Figure 1] and [Figure 2], the known hanging lock 1 needs to be provided with a plurality of holes 12 on the lock body 11 of the hanging lock 1 due to design requirements, and the necessary components such as the required lock core 13 (and its respective lock beads and springs), the fixing pin 14, etc. are placed through the holes 12; after the components are assembled, each hole 12 is sealed with a cover plate 15, and for the sake of aesthetics, the hanging lock 1 together with the fixing pin 14 and the cover plate 15 need to be further polished so that the fixing pin 14 and the cover plate 15 are not too prominent on the hanging lock 1.

The assembly and processing procedures of the above-mentioned known hanging lock 1 are quite complicated, which easily leads to high processing costs. In addition, no matter how the hanging lock 1 together with the fixing pin 14 and the cover plate 15 are further polished, in practice, the hanging lock 1, the fixing pin 14 and the cover plate 15 are difficult to integrate into one, and the assembly traces of these objects can be easily found with the naked eye, making the hanging lock 1 present a rather rough feeling, and failing to meet the integrity and refinement requirements of the product.

Therefore, it is necessary to further design the structure of the lock 1 in order to reduce processing costs, improve product integrity and enhance refined performance.

The present invention is a lock core and a hanging lock thereof, which is mainly to overcome the common problem that hanging locks are used to assemble parts, and many holes are required on the lock body to achieve the purpose, thereby destroying the integrity of the hanging lock product and failing to meet the requirements of refinement.

To achieve the above-mentioned purpose, the present invention provides a lock core and a lock therefor. The lock core and the lock hook of the present invention include a lock body, a lock core and a lock hook; wherein the bottom of the lock body is in a plane shape, and the lock body is inwardly concave from the bottom to form a first space and a second space, and one side of the first space and the second space are in a connected shape, and a groove is extended from the upper side of the first space to the two sides, and a first lock hole and a second lock hole are inwardly concave on the upper side of the lock body, and the first lock hole and the second lock hole are respectively connected with the grooves on the upper side of the first space, and one end of the first lock hole is connected to a through hole, and the diameter of the through hole is slightly smaller than the diameter of the first lock hole, and the through hole penetrates to the bottom of the lock body, and a screw hole is provided at the bottom of the second lock hole. The lock core has a lock core and a lock ball receiving part; wherein the lock core is cylindrical and arranged in the first space of the lock body, the lock core has a key hole groove for the key to extend along its axial direction, and has a plurality of bead holes along the wall of the key hole groove, and a neck with a slightly smaller diameter is formed above the lock core, and the neck has a concave portion formed along its axial direction; wherein the lock ball receiving part is cylindrical and arranged in the second space of the lock body The lock ball receiving part has a concave ring portion that is inwardly concave along its axial direction, and the concave ring portion is used to abut against the outside of the lock core. The lock ball receiving part has multiple chambers along the concave ring portion, each chamber corresponds to each bead hole of the lock core, and each chamber is provided with a lower bead body, an upper bead body and a spring. The lock ball receiving part has an axial fixing hole along its axial direction and a radial fixing hole along its radial direction on its upper side. The lock hook is formed into a first rod body part and a second rod body part that are connected to each other. The first rod body part extends into and is fixed in the first lock hole of the lock body, and the second rod body part has a notch at the near end corresponding to the direction of the first rod body part.

The application effect of the present invention through the above-mentioned design structure is that the present invention makes the only through hole of the entire lock body located at the bottom of the lock body, which is difficult to detect unless it is deliberately turned over. The through hole of the first lock hole can be used for drainage, so that the present invention has good drainage performance. A screw is used to lock the screw hole at the bottom of the second lock hole of the lock body into the axial fixing hole above the lock ball receiving part, so that the lock core and the lock body are combined, so that the entire lock body of the present invention can hardly see any holes or assembly screws, and the finished product after assembly does not need to be further polished, which can save processing costs. Moreover, the finished product after assembly can maintain the high integrity of the product and improve the exquisite texture of the product.

One end of the first lock hole 34 is connected to a through hole 36. The diameter of the through hole 36 is slightly smaller than that of the first lock hole 34, and the through hole 36 penetrates to the bottom of the lock body 3. A screw hole 351 is provided at the bottom of the second lock hole 35. As shown in [FIG. 3] and [FIG. 4], the lock core 4 has a lock core 41 and a lock ball receiving member 42. The lock core 41 is cylindrical and has a key hole groove 411 along its axial direction for a key to pass through. When implemented, the key hole groove 411 can penetrate the upper and lower ends of the lock core 41 and extend along the key. The keyhole groove 411 has a plurality of bead holes 412 on its wall, and the bead holes 412 are connected to the outer surface of the lock core 41. The lock core 41 forms an annular groove 413 near the bottom, and the annular groove 413 is connected to a flange 414. The flange 414 has a diameter slightly larger than the diameter of the lock core 41. The lock core 41 has a concave annular groove 415 formed along its radial direction in the middle section of the outer portion, and the concave annular groove 415 does not exceed the radius of the lock core 41. A neck 416 with a slightly smaller diameter is formed above the lock core 41, and a concave portion 417 is formed at the neck 416. The lock ball receiving member 42 is cylindrical and has a concave portion 417 along its axis. A concave ring portion 421 is formed inwardly, and the concave ring portion 421 has a plurality of chambers 422. Each chamber 422 is provided with a lower bead 423, an upper bead 424 and a spring 425. A convex rib 426 is formed near the end below the concave ring portion 421. The convex rib 426 is formed corresponding to the radial curvature of the concave ring portion 421, and the convex rib 426 is slightly higher than the height of the concave ring portion 421. The locking ball receiving part 42 has an axial fixing hole 427 along its axial direction on the top, and a radial fixing hole 428 along its radial direction near the top.

The lock hook 5 is composed of a first rod portion 51 and a second rod portion 52 connected to each other. A screw hole 511 is provided on the bottom surface of the first rod portion 51, and a notch 53 is provided near the end of the second rod portion 52 in the direction corresponding to the first rod portion 51.

Please refer to [Fig. 3] [Fig. 4] [Fig. 5], when the present invention is assembled, first, the lock core 41 and the lock ball receiving member 42 of the lock core 4 are assembled, wherein the spring 425, the upper bead 424 and the lower bead 423 are placed in each chamber 422 of the lock ball receiving member 42 in sequence. When implemented, the sizes of the upper bead 424 and the lower bead 423 in each chamber 422 can be changed differently according to the design, and then the concave ring portion 421 of the lock ball receiving member 42 is abutted against the outside of the lock core 41, and the convex rib 426 of the lock ball receiving member 42 is embedded in the annular groove 413 of the lock core 41. At this time, each chamber 422 of the lock ball receiving member 42 will correspond to each bead hole 412 of the lock core 41. A stopper 429 is inserted and fixed through the radial fixing hole 428 of the lock ball receiving member 42, and one end of the stopper 429 is inserted into the concave annular groove 415 of the lock core 41. Then, the lock core 41 of the lock core 4 is placed in the first space 31 of the lock body 3, and the lock ball receiving member 42 of the lock core 4 is placed in the second space 32 of the lock body 3. This allows the lock core 4 to be completely inserted into the lock body 3. At this time, the lock core 41, the lock ball receiving part 42 and the bottom of the lock body 3 are all in a flat shape. Then, a screw 37 is used to lock the screw hole 351 at the bottom of the second lock hole 35 of the lock body 3 into the axial fixing hole 427 above the lock ball receiving part 42, further combining and fixing the lock core 4 and the lock body 3.

Next, a steel ball 6 is placed through the first lock hole 34 on the lock body 3 and guided into the groove 33. In practice, the diameter of the groove 33 is larger than that of the steel ball 6, so that the steel ball 6 can roll along the groove 33 to the second lock hole 35. However, the diameter of the groove 33 adjacent to the outlet of the second lock hole 35 is slightly smaller than the diameter of the steel ball 6, so that a portion of the steel ball 6 can extend slightly from the outlet of the groove 33 into the second lock hole 35, but the steel ball 6 can be received by the groove 33. The outlet is restricted so that the lock will not fall completely into the second lock hole 35. Then, a spring 7 is placed in the first lock hole 34 of the lock body 3, and the first rod 51 of the lock hook 5 is inserted into the first lock hole 34 of the lock body 3. Then, a bolt 8 is locked from the through hole 36 at the other end of the first lock hole 34 into the screw hole 511 on the bottom surface of the first rod 51. In this way, the lock hook 5 is assembled with the lock body 3 by locking the first rod 51 with the bolt 8.

Please refer to [Figure 6] [Figure 7] [Figure 8] to lock the present invention. First, insert the matching key 9 into the key hole slot 411 of the lock body 41 and rotate it. When the correctly matched key 9 is inserted into the key hole slot 411, the lower bead 423 and the upper bead 424 of each bead hole 412 in the lock body 41 will be completely pressed back. In each chamber 422 of the lock ball receiving member 42, the lock core 41 can be smoothly rotated by the key 9, and at the same time, the second rod body 52 of the lock hook 5 is aligned and inserted into the second lock hole 35 of the lock body 3. At the same time, the first rod body 51 will be pressed down and compress the spring 425 at the bottom thereof; as shown in [Fig. 7], as the lock core 41 When the lock body 42 is rotated, the neck 416 of the lock body 41 will rotate and push the steel ball 6 to move from the groove 33 to the second lock hole 35, and the concave ring groove 415 of the lock body 41 will rotate along the stopper 429 of the lock ball receiving member 42. When one end of the concave ring groove 415 of the lock body 41 abuts against the stopper 429, the steel ball 6 will fall into the second rod body portion in the second lock hole 35. 52 is locked in the slot 53, so as shown in [Fig. 8], the second rod 52 is locked by the steel ball 6 and cannot be withdrawn from the second lock hole 3 5 of the lock body 3. In this way, the locking operation of the present invention is completed, and the anti-theft protection of the locking is effectively ensured. Subsequently, the key 9 can be withdrawn from the key hole slot 411 of the lock body 41.

As mentioned above, when you want to unlock, please refer to [Figure 9] [Figure 10] [Figure 11], insert the matching key 9 into the key hole slot 411 of the lock core 41 again and rotate it in the opposite direction. When the lock core 41 is driven to rotate in the opposite direction, as shown in [Figure 10], the concave ring groove 415 of the lock core 41 will rotate in the opposite direction along the stop member 429 of the lock ball receiving member 42. When the other end of the concave ring groove 415 of the lock core 41 abuts against the stop member 429, as shown in [Figure 11], the steel ball 6 just retreats into the concave portion 417 of the neck portion 416 of the lock core 41, so that the steel ball 6 is disengaged from the clamping of the second rod body portion 52 of the lock hook 5. At the same time, the lock body 3 is released. The spring 425 in the first lock hole 34 will push the first rod 51 upwards, so the first rod 51 together with the second rod 52 will push the entire hook 5 upwards, so that the second rod 52 will completely disengage from the second lock hole 35 of the lock body 3. However, the bottom of the first rod 51 is locked by the bolt 8 through the through hole 36 below the first lock hole 34, so the first rod 51 will not completely disengage from the first lock hole 34 of the lock body 3, but will still remain partially in the first lock hole 34. In this way, the unlocking operation is completed, and the second rod 52 can be disengaged from the locked object to completely remove the present invention.

As mentioned above, the through hole 36 of the entire lock body 3 of the present invention is located at the bottom of the lock body 3, and it is difficult to see unless the lock body 3 is turned over intentionally. In addition, the through hole 36 connected to the first lock hole 34 can be used for drainage, so that the present invention still has good drainage performance. A screw 37 is further used to lock the screw hole 351 at the bottom of the second lock hole 35 of the lock body 3 into the top of the lock ball receiving member 42, so that the lock The core 4 and the lock body 3 are combined and fixed in place, so that the existence of the screw 37 and the screw hole 351 cannot be seen from the outside, and the lock core 41, the lock ball receiving part 42 and the lock body 3 in the lock core 4 are all in a flat shape after being combined, and no additional grinding processing is required, which is enough to save processing costs, and the invention as a whole can maintain the high integrity of the product and improve the exquisite texture of the product.

As shown in [FIG. 12] [FIG. 13], in another embodiment of the present invention, in order to enhance the locking effect of the present invention, two recesses 417 may be provided on the neck 416 of the lock core 41 of the lock core 4, and the two recesses 417 will be located at two corresponding positions of the neck 416 of the lock core 41, and a groove 417 is provided in the side end of the groove 33 connected to the first lock hole 34. The steel ball 6 is also provided in the side end of the groove 33 connected to the second lock hole 35, and the key hole groove 411 does not penetrate the lock body 41. In practice, the key hole groove 411 is preferably formed only from the bottom of the lock body 41 to the neck 416. In addition, a notch is also formed in the second rod body 52 at the position corresponding to the notch 53 of the first rod body 51. 53; Therefore, as shown in [Figure 12], when the lock is engaged and the lock core 41 is driven to rotate, the neck 416 of the lock core 41 will rotate and push the two steel balls 6 to move from the two sides of the groove 33 to the first lock hole 34 and the second lock hole 35 respectively, and the concave annular groove 415 of the lock core 41 will rotate along the stopper 429 of the lock ball receiving member 42. When one end of the concave annular groove 415 abuts against the stopper 429, the two steel balls 6 fall into the notch 53 of the first rod body 51 in the first lock hole 34 and the notch 53 of the second rod body 52 in the second lock hole 35, respectively, so that the first rod body 51 and the second rod body 52 are both clamped by a steel ball 6 at the same time, thereby enhancing the locking effect.

As shown in [Figure 13], when the lock body 41 is driven to rotate in the reverse direction to unlock, the concave annular groove 415 of the lock body 41 also rotates in the reverse direction along the stopper 429 of the lock ball receiving member 42. When the other end of the concave annular groove 415 of the lock body 41 abuts against the stopper 429, the two steel balls 6 are respectively returned to the two concave parts 417 of the neck 416 of the lock body 41, so that the two steel balls 6 are simultaneously released from the first rod body 51 and the second rod body 52 of the lock hook 5; at this time, the spring 7 in the first lock hole 34 of the lock body 3 is released. The force will also push the first rod 51 upward, so the first rod 51 and the second rod 52 will push the entire hook 5 upward, so that the second rod 52 will completely disengage from the second lock hole 35 of the lock body 3. However, the bottom of the first rod 51 is locked by the bolt 8 through the through hole 36 below the first lock hole 34, so the first rod 51 will not completely disengage from the first lock hole 34 of the lock body 3, but will still remain partially in the first lock hole 34, thus completing the unlocking operation.

The above is only a preferred embodiment of the present invention. It should be understood that the description and illustrations in the text are not limited to the invention concept of this case. The words and terms used in the text are only for the purpose of explaining the present case and should not be regarded as limiting. Generally speaking, simple modifications and equivalent changes made by those with ordinary knowledge in the relevant technical field according to the scope of the patent application of this invention and the content of the specification should still fall within the scope of the patent of this invention.
