[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a padlock cylinder replacement and a lock, comprising a lock body 1, an adapting mechanism 3 and a disassembly mechanism 4;

[0033] The lock body 1 is provided with a switch mechanism 2 for opening and closing the lock, the lock body 1 is provided with an adapter mechanism 3 for limiting the disassembly mechanism 4, and the adapter mechanism 3 is provided with a disassembly mechanism 4 for facilitating replacement of the lock core;

[0034] The switch mechanism 2 includes a bearing assembly and an insertion assembly, wherein the bearing assembly is arranged inside the lock body 1 and the insertion assembly is arranged inside the lock body 1;

[0035] The cooperation between the bearing component and the insertion component facilitates the padlock to be opened and closed;

[0036] The adapting mechanism 3 includes a connecting component and a fixing component, wherein the connecting component is arranged inside the lock body 1 and the fixing component is arranged on the top of the connecting component;

[0037] The connection assembly and the fixing assembly facilitate the installation and disassembly of the limit disassembly and assembly mechanism 4, and the adapter mechanism 3 can also facilitate its separate disassembly, maintenance and replacement operations;

[0038] The disassembly and assembly mechanism 4 includes a pick-and-place assembly and a locking assembly, wherein the pick-and-place assembly is arranged inside the adapting mechanism 3, and the locking assembly is arranged inside the lock body 1;

[0039] The lock core can be directly removed and replaced by the pick-and-place assembly and the locking assembly, and the new lock core can be taken out for locking and fixing operations, so as to reduce maintenance costs. At the same time, the operation is simple and convenient.

[0040] The lock core can be fixed by tightening the locking assembly, and the lock core can be removed by loosening the locking assembly. The lock core can be replaced according to the tightness or looseness of the locking assembly.

[0041] in;

[0042] like Figure 3 As shown, the bearing assembly includes a blind hole 24, which is respectively opened at both ends of the top of the lock body 1, and the spring 21 is arranged at the bottom of the inner cavity of one side of the blind hole 24. The blind hole 24 is opened for installing the spring 21 and adapting the two ends of the lock beam 22.

[0043] like Figure 3 As shown, the fixing assembly includes a locking beam 22, which is slidably connected to the inside of a blind hole 24 on one side. One end of the locking beam 22 is located inside the spring 21 and connected thereto. The locking beam 22 is mainly used to realize the opening and closing operations of the padlock, and can also realize the hanging operation to achieve the actual effect of the padlock.

[0044] like Figure 3As shown, an arc groove is provided on the inner side wall of the lock beam 22, and lock tongues 23 are placed on both sides of the inner cavity of the lock body 1. The lock tongue 23 is located on the inner side of the lock beam 22 and the arc groove. The lock beam 22 is U-shaped, and the arc groove is provided to adapt to the lock tongue 23. The lock tongue 23 in the padlock mainly plays a switching and locking role. The lock tongue 23 is an important component of the padlock and is responsible for controlling the opening and closing of the lock. Specifically, the lock tongue 23 realizes the locking and unlocking functions of the padlock by cooperating with the lock core. When the correct key is inserted and rotated, the mechanical structure inside the lock core will move the lock tongue 23, thereby opening the padlock. Conversely, when the lock tongue 23 is in a locked state, the padlock cannot be opened.

[0045] As shown in the figure, the padlock is in a locked closed state at this time. When it needs to be opened, the corresponding key is inserted into the interior of the lock core body 41 from the bottom, and then the key is turned. The key will drive the components inside the lock core body 41 to rotate, thereby driving the rotating member at the top to rotate together. Since a connecting groove is provided on the outer side of the top rotating member, the connecting groove and the lock tongue 23 are adapted to each other at this time, and the activity space of the lock tongue 23 can be increased. Since the lock tongue 23 will no longer press against the lock beam 22 and the arc groove provided by the lock beam 22, the lock beam 22 moves upward according to the elastic lifting of the spring 21. At this time, one end of the lock beam 22 will push the corresponding lock tongue 23 to move in the above-mentioned increased space, and then one end of the lock tongue 23 directly disengages from the lock body 1 and the corresponding blind hole 24 provided in the lock body 1, thereby completing the work of opening the padlock;

[0046] When the padlock needs to be fixed on the door body or the object to be closed, the lock beam 22 is directly passed through the nose ring or handle of the door body, and the lock body 1 is rotated so that the lock body 1 and the lock beam 22 are symmetrically arranged up and down, and the closed end of the lock beam 22 is aligned with the corresponding blind hole 24. At this time, the lock beam 22 and the lock body 1 are directly pressed to cause the closed end of the lock beam 22 to be inserted into the blind hole 24 of the lock body 1. Since a coil spring is provided on the top of the lock core body 41, the reset operation will be realized after the padlock is rotated to open. Based on the above, the lock tongue 23 is limited by the lock core body 41 and the space for its movement is reduced, which will directly push it to the preset position, and the arc groove will be adapted to complete the limitation of the lock beam 22 and the locking operation of the padlock.

[0047] further;

[0048] like Figure 5 As shown, the connecting assembly includes a connecting sleeve 31, which is bolted to the inner wall of the lock body 1. An adapting hole 33 is provided on the top of the connecting sleeve 31. The connecting sleeve 31 is used for limiting the position when the lock core is replaced, and the opened adapting hole 33 can achieve full adaptation and limiting operation.

[0049] like Figure 5As shown, the fixing assembly includes a first bolt 32 and a first mounting hole. The first mounting hole is opened at the top of the connecting sleeve 31. The first bolt 32 is threadedly connected to the inside of the first mounting hole. The opening of the first mounting hole facilitates the connection and installation of the first bolt 32, and the first bolt 32 plays a role in locking and fixing the connecting sleeve 31.

[0050] like Figure 5 As shown, a second mounting hole is provided at the bottom of the inner cavity of the blind hole 24 on the other side, and the first bolt 32 is connected to the connecting sleeve 31 through the second mounting hole and the first mounting hole. The second mounting hole is provided as described above and is mainly used to adapt the first bolt 32 so as to facilitate the locking and fixing operation of the connecting sleeve 31.

[0051] As shown in the figure, it is in the installed state. When disassembly is required, the padlock is in the open state, that is, the left end of the lock tongue 23 is separated from the lock body 1 and located above it. At this time, the corresponding tool is directly inserted into the corresponding blind hole 24, and the first bolt 32 is adapted. The tool is directly rotated to drive the first bolt 32 to rotate, and the first bolt 32 is gradually separated from the connecting sleeve 31 through the threaded connection relationship, that is, separated from the first mounting hole, and then the connecting sleeve 31 is directly made to gradually slide down and separate from the interior of the lock body 1. At this time, the disassembly operation of the connecting sleeve 31 is completed;

[0052] As for the installation of the connecting sleeve 31, the above disassembly method can be reversed. Since a hole adapted to the connecting sleeve 31 is provided at the bottom of the lock body 1, the new connecting sleeve 31 after replacement or repair can be directly slid into the interior of the lock body 1, and then the first bolt 32 is driven to rotate through the corresponding external tool and extended into the corresponding first mounting hole, thereby connecting with the connecting sleeve 31 and fixing the connecting sleeve 31.

[0053] Preferred;

[0054] like Figure 4 As shown, the pick-and-place assembly includes a lock core body 41, which is slidably located inside the adapter hole 33. A first connecting hole 42 is provided on one side of the lock core body 41. The main function of the lock core body 41 in the padlock is to control the opening and closing of the lock. The lock core body 41 cooperates with the key through the internal mechanical structure to ensure that only the correct key can open the lock, thereby ensuring the safety of the padlock. The first connecting hole 42 is mainly used to adapt to the second bolt 43 to assist it in completing subsequent disassembly, assembly, replacement and maintenance operations.

[0055] like Figure 4 and 3As shown, the locking assembly includes a second connecting hole 44, which is opened on one side of the lock body 1. The first connecting hole 42 and the second connecting hole 44 are both threadedly connected with a second bolt 43. The opening of the second connecting hole 44 is convenient for adapting the second bolt 43, and the second bolt 43 mainly fixes the lock core body 41 inside the lock body.

[0056] As shown in the figure, it is in the installed state. When the lock core body 41 needs to be disassembled and replaced with a new one, the damaged lock core body 41 needs to be disassembled first. First, use a corresponding tool to insert it into the first connecting hole 42, and then adapt it to one end of the second bolt 43. When the two are adapted, the second bolt 43 is driven to rotate together by rotating the tool until the second bolt 43 is completely separated from the first connecting hole 42 and the lock core body 41. Then, the lock core body 41 will slowly slide downward due to its own weight, and separate from the connecting sleeve 31 and the interior of the lock body 1 to complete the disassembly operation;

[0057] After the removal is completed, the new lock core body 41 can be taken out for installation. Based on the above, the connecting sleeve 31 is in the installed state and has not been removed. At this time, the new lock core body 41 needs to be moved from bottom to top and inserted into the adapting hole 33 opened in the connecting sleeve 31, and the two are slid and continue to slide upward until the bottoms between the two are horizontally aligned, and the top of the lock core body 41 is adapted to the top of the inner cavity of the lock body 1;

[0058] Based on the above, if Figure 3 The top of the inner cavity of the lock body 1 is provided with a groove adapted to the lock core body 41, which is mainly used to limit the top position of the new lock core body 41 when installing it to ensure the accuracy of installation. At the same time, the top of the outer side of the lock core body 41 is located between the two sets of lock tongues 23, and the two sets of lock tongues 23 are two stainless steel balls as shown in the figure;

[0059] When the above work is completed, the second bolt 43 can be rotated in the reverse direction, and the second bolt 43 is first threadedly connected to the second connecting hole 44. The second bolt 43 will continue to extend, and then extend to the first connecting hole 42 opened in the lock core body 41, and be threadedly connected thereto, until it extends to a position and state where it cannot be extended. At this time, the second bolt 43 cannot be rotated, and the locking and fixing state is completed.

[0060] The above-mentioned connecting sleeve 31 is used to limit the position of the lock core body 41 when installing it, and at the same time, the lock core body 41 can be protected secondary to avoid damage. The connecting sleeve 31 and the lock core body 41 are both installed and fixed by bolting, and both are easy to disassemble and replace. The above-mentioned method can achieve the advantage of being able to replace the lock core of the existing padlock separately when it is damaged. The method of replacing the lock core separately can not only reduce the cost of replacement and maintenance, but also facilitate people's operation during actual use. The operation is simple and convenient, and the disassembly operation can be completed by tightening and loosening the corresponding tool.

[0061] Based on the above, the present invention includes but is not limited to bolting and fixing methods, and may also use elastic snap-fitting and other methods to fix the lock core during disassembly, assembly and replacement operations.

[0062] A lock comprises a lock cylinder.
