Referring to fig. 1, 2 and 4, the lock body 10 further includes a mounting cavity 140 communicating with the lock hole 130, and the transmission mechanism 30 is mounted in the mounting cavity 140. The lock body 10 of the embodiment comprises a lock case 110 and a mounting seat 120 located in the lock case 110, and the lock hole 130 and the mounting cavity 140 are defined by the lock case 110 and the mounting seat 120. The lock case 110 may be made of a metal material having a high strength, so as to support and protect the internal structure thereof, and the mounting seat 120 may be made of a plastic material, so as to assemble other internal components and parts, and facilitate manufacturing. The lock shell 110 and the mounting base 120 are detachably connected, and specifically, the lock shell 110 and the mounting base 120 are respectively provided with a connecting hole which is matched with each other, and the lock shell 110 and the mounting base 120 are detachably and fixedly connected through the matching of the connecting piece 160 and the connecting hole. The arrangement is favorable for the disassembly and the assembly of the whole structure.

In one embodiment, the transmission mechanism 30 includes a pressing block 310, an elastic element 330 and a push rod 320, the magnetic member 50 is mounted on the push rod 320, the pressing block 310 is movably connected with the lock body 10, one side of the pressing block 310 extends into the lock hole 130, the other side is in transmission connection with the push rod 320, and the elastic element 330 provides an elastic force to make the rod 321 have a tendency to move toward the first position or the second position; when the locking hook 20 is inserted into the locking hole 130, the pressing block 310 is driven to move, and the pressing block 310 further drives the push rod 320 to slide along the installation cavity 140, so as to drive the magnetic member 50 to move between the first position and the second position.

In one arrangement, the pressing block 310 and the pushing rod 320 may be fixed as a single body, i.e., they constitute a transmission member. In this arrangement, the movable connection between the pressing block 310 and the lock body 10 may be a sliding connection, and the installation cavity 140 is configured to define a linear slideway for the transmission member formed by the pressing block 310 and the push rod 320 to slide, that is, the opening shape of the slideway of the installation cavity 140 is configured to be matched with the outer contour shape of the transmission member formed by the pressing block 310 and the push rod 320, and the linear slideway is extended towards the operation position. The elastic element 330 may be in the form of a tension spring, a compression spring, or a spring plate, and the first position and the second position are two different positions of the slide formed by the installation cavity 140 in the length direction. In the process that the locking hook 20 slides along the locking hole 130 and moves between the unlocking position and the locking position, the locking hook 20 drives the magnetic member 50 to move between the first position and the second position through the transmission member formed by the pressing piece 310 and the push rod 320, and the elastic element 330 drives and resets the pressing piece 310 and the push rod 320 when the locking hook 20 cancels the acting force on the pressing piece 310, in the process, because the distance between the magnetic member 50 and the sensing detection element 2a is obviously changed, the reliability of the detection result can be effectively ensured.

In the case that the pressing member 310 and the pushing rod 320 are provided as an integral structure, the integral structure formed by the pressing member 310 and the pushing rod 320 may also rotate relative to the lock body 10. In this arrangement, the installation cavity 140 forms an arc-shaped slide for the pressing block 310 and the pushing rod 320 to swing integrally, the elastic element 330 may be a torsion spring, a tension spring, a compression spring, or a spring plate, and the first position and the second position are two positions of different arc angles of the arc-shaped slide formed by the installation cavity 140. In the process that the locking hook 20 slides along the locking hole 130 and moves between the unlocking position and the locking position, the locking hook 20 drives the magnetic member 50 to swing between the first position and the second position through the pressing block 310 and the push rod 320, and the elastic element 330 drives and resets the pressing block 310 and the push rod 320 when the locking hook 20 cancels the acting force on the pressing block 310, and in the process, the distance between the magnetic member 50 and the sensing detection element 2a is obviously changed, so that the reliability of the detection result can be effectively ensured.

In another arrangement, referring to fig. 2 to 7, the pressing block 310 and the pushing rod 320 are separately arranged, and the installation cavity 140 is correspondingly arranged as the first cavity 141 and the second cavity 142, in this case, the pressing block 310 is rotatably connected to the cavity wall of the first cavity 141, and the elastic element 330 provides an elastic force to make the rod 321 have a tendency to move toward the first position.

In this embodiment, the pressing block 310 includes a mounting portion 311, and a first transmission portion 312 and a second transmission portion 313 respectively connected to two opposite sides of the mounting portion 311, the mounting portion 311 is rotatably connected to the cavity wall of the first cavity 141, and a part of the structure of the first transmission portion 312 extends into the locking hole 130 and is located on the operation path of the locking hook 20. The specific rotating connection manner may be that a shaft hole 314 is disposed on the mounting portion 311, a pivot 340 is connected to the cavity wall of the first cavity 141, and the pressing block 310 is sleeved on the pivot 340 through the cooperation between the shaft hole 314 and the pivot 340. The push rod 320 includes a driving block 322 and a rod 321, the magnetic element 50 is fixed on the rod 321 and located at an end of the rod 321 away from the driving block 322, the driving block 322 includes a base 323 and a driving portion 324 connected to a sidewall of the base 323 and extending toward the pressing block 310, the elastic element 330 is supported between the base 323 and a cavity wall of the mounting cavity 140, and the second transmission portion 313 abuts against a side of the driving portion 324 away from the elastic element 330.

Because the pressing block 310 and the push rod 320 are separately disposed, the first cavity 141 extends transversely in the lock body 10 (i.e., extends horizontally in the figure), and the second cavity 142 extends in the height direction of the lock body 10, the operation position corresponding to the computer key 2 is disposed at the bottom of the lock body 10, and the rotation of the pressing block 310 is converted into the linear motion of the push rod 320, so that the magnetic member 50 moves linearly close to or away from the operation position under the driving of the push rod 320, and thus the distance between the magnetic member 50 and the sensing detection element 2a on the computer key 2 changes more significantly, and the obtained detection result is more accurate. Meanwhile, due to the structural design, the existing padlock is convenient to modify and obtain, the modification cost is low, and the padlock is beneficial to large-scale production.

In order to ensure the stability during the operation, the elastic element 330 of this embodiment is a spring and is in the form of a compressed spring, referring to fig. 5, a limiting groove 150 is formed on the wall of the mounting cavity 140 at a position corresponding to the base portion 323, a positioning groove 325 is formed on the base portion 323, one end of the elastic element 330 is inserted into the limiting groove 150, and the other end is inserted into the positioning groove 325. By this arrangement, the elastic member 330 acting as a spring is effectively restrained during deformation, and the structure is more reliable.

The end surface of the second transmission part 313 contacting the driving part 324 is formed into a curved surface. Because the second transmission part 313 jacks up the driving part 324 in the process that the pressing block 310 drives the push rod 320 to move, the end surface of the second transmission part 313 in contact with the driving part 324 is formed into a cambered surface, and the problem that the contact surface of the second transmission part 313 and the driving part 324 is worn to generate debris or generate large abnormal sound in the process can be effectively avoided.

As a modified design in which the pressing block 310 and the pushing rod 320 are separately provided, it is also possible that in the case that the pressing block 310 and the pushing rod 320 have substantially the same structure, the installation position of the elastic element 330 is different, the elastic element 330 is used for acting on the pressing block 310 and providing an elastic force to drive the pressing block 310 to twist relative to the cavity wall of the installation cavity 140, and the second transmission part 313 is rotationally connected with the driving block 322. In this embodiment, the installation cavity 140 is also configured as the first cavity 141 and the second cavity 142, and the rod 321 of the push rod 320 slides linearly in the second cavity 142, so that the effect substantially similar to that of the previous embodiment is also provided, and the description is omitted here.

In the two structural forms that the pressing block 310 and the push rod 320 are separately arranged, the pressing block 310 is rotatably arranged, on the basis, a flared groove 143 extending towards the direction away from the outlet of the lock hole 130 is formed at one end of the first cavity 141 connected with the lock hole 130, and in the process that the lock hook 20 is inserted into the lock hole 130, the lock hook 20 drives the first transmission part 312 to swing towards the flared groove 143. In this embodiment, the pressing block 310 is installed at the limit position corresponding to the inside of the lock hole 130 when the lock hook 20 is at the locking position, and then through the arrangement of the flared groove 143, when the lock hook 20 moves to the limit position, the first transmission part 312 of the pressing block 310 abuts against the groove wall of the flared groove 143, at this time, the pressing block 310 also rotates to the limit position without further deflection, so that when the lock hook 20 moves to the locking position, the magnetic member 50 just moves to the second position, and thus, the action response between the two positions is formed, and thus, the accuracy of the detection result can be further improved.

In two kinds of structural style that above briquetting 310 and push rod 320 set up for the components of a whole that can function independently, in order to promote the reliability, the utility model discloses further with the internal diameter of second cavity 142 and the external diameter looks adaptation of the body of rod 321. Through setting up like this, the phenomenon is rocked in the difficult appearance deflection of body of rod 321 in the operation process, and drive magnetic part 50 is more accurate when first position and the motion of second position spare like this, and the testing result is also more reliable.

Further, a guide inclined plane 220 is formed at the end part of the lock hook 20 contacting the pressing block 310, and by the arrangement of the guide inclined plane 220, when the pressing block 310 is twisted to adjust the angle, the scraping action of the lock hook 20 on the pressing block 310 is small, so that when the padlock is used for a long time, the situation that chips fall into the lock hole due to the scraping action of the lock hook 20 on the pressing block 310 is avoided, and the smoothness of the padlock during the long-time use can be ensured.

The above is only the optional embodiment of the present invention, and not limiting the patent scope of the present invention, all under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the specification and the attached drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
