[0032] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Embodiment 1:

[0034] A punch-free lock body structure, such as Figure 1-8 As shown, it includes a housing 100 and a locking tongue structure 200 .

[0035] As shown in the figure, the housing 100 is used to limit the lock tongue structure 200, and the panel 120 and the base 110 at the lock end are integrally formed, and the top of the base 110 is limited by a cover plate 130.

[0036] In the structural setting of this solution, the panel 120 and the base 110 are integrally formed and do not need to be fixed with screws. This overcomes the problems in the prior art where the screws of the panel 120 are loose or fall off, causing the door lock panel 120 to deviate, the lock hole to loosen, and the like, thereby increasing the service life of the door lock.

[0037] The base 110 and the panel 120 are vertically arranged and a through hole 140 is provided at the connection point for the locking tongue to enter and exit. The through hole 140 includes a first protrusion 141 and a second protrusion 142 .

[0038] The first protrusions 141 are arranged on both sides of the panel end of the through hole 140 to limit the silent seat 150;

[0039] In the structural setting of the present scheme, the lock tongue moves in the through hole 140, and the metals rub against each other, which easily produces a loud impact sound. After long-term use, the impact sound will become more and more obvious and easily cause wear. Therefore, a silent seat 150 is provided in the scheme. The silent seat 150 can not only achieve a silent effect, but also limit the lock tongue to prevent the lock tongue from rotating due to external force.

[0040] Specifically, the recessed portions 151 at both ends of the silent seat 150 are engaged with the first convex portions 141 , and the locking tongue moves between the first convex portions 141 .

[0041] The second protrusion 142 is disposed at the base end of the through hole 140 and is used to limit the retraction distance of the locking tongue;

[0042] A mute block may be disposed on the surface of the second convex portion 142 to achieve a mute effect, and the mute block may be adjusted according to actual needs. In this embodiment, the surface of the second convex portion 142 further includes a mute block.

[0043] In this embodiment, the silent seat 150 and the silent block are made of POM material to avoid noise caused by friction between the lock tongue and the housing 100. At the same time, the material has strong wear resistance, thereby extending the service life of the lock.

[0044] Connecting pieces 111 are evenly distributed on the top of the base 110 for limiting the cover plate 130 .

[0045] In this embodiment, the connecting member 111 is a bendable limiting protrusion 1111, which is bent and fitted with a groove corresponding to the edge of the cover plate 130 to form an inner cavity and a limiting lock body structure.

[0046] In the structural setting of this solution, the base 110 is directly fixed by the connecting member 111 and the cover plate 130, and no special tools are required, so it is easy to disassemble and assemble.

[0047] The panel 120 further includes a fixing hole 121 for limiting the lock body on the door.

[0048] The base 110 includes a limiting structure 112 for limiting a locking tongue structure 200 , and the locking tongue structure 200 is fixed on the limiting structure 112 .

[0049] The lock tongue structure 200 of the present solution is the prior art. A spring is sleeved at the bottom of the lock tongue assembly, and the other end of the spring is sleeved and limited on a limiting column on the side of the housing 100 .

[0050] The bolt assembly includes a connecting rod connected to the bottom of the bolt body, and two elastic members are sleeved on the outer side of the connecting rod. The toggle block is limited in the middle of the bolt structure 200, and the toggle block is driven by the lever principle to link the bolt assembly up and down.

[0051] The lock tongue body can be a single hook, a double hook, a square lock or other, and the lock tongue body is an oblique tongue structure in this embodiment. As the technical common sense known to those skilled in the art, no further elaboration is made here.

[0052] Specifically, during the process of assembling the locking tongue structure 200 , after the locking tongue structure 200 is placed, the cover plate 130 is placed on the top of the base 110 , and the connector 111 on the cover plate 130 is attached to the cover plate 130 .

[0053] Embodiment 2

[0054] The features of this embodiment that are different from those of the first embodiment are as follows:

[0055] In this embodiment, referring to the figure, the housing 100 is integrally formed and includes a base 110, a panel 120 and a cover plate 130. The cover plate 130 can be folded along the connection.

[0056] The housing 100 provided in this embodiment is integrally formed, which makes it easier to assemble the lock body.

[0057] The top sides of the base 110 include limiting protrusions 1111. After the cover plate 130 is folded, the limiting protrusions 1111 are bent, which increases the stability of the cover plate 130 and the base 110, making the whole more firm and stable.

[0058] In actual use, after the lock body is assembled, the cover plate 130 of the housing 100 will not be repeatedly opened and closed, and the housing 100 can be made of aluminum, stainless steel or other bendable metal materials. In this embodiment, the housing 100 is made of iron.

[0059] Specifically, during the process of assembling the locking tongue structure 200 , after inserting the locking tongue structure 200 , it is only necessary to fold the cover plate 130 and fit the limiting protrusion 1111 on the cover plate 130 to the cover plate 130 .

[0060] Embodiment 3

[0061] The features of this embodiment that are different from those of Embodiment 1 and Embodiment 2 are as follows:

[0062] In this embodiment, the connecting piece 111 at the top of the base 110, as shown in the figure, is a hinge shaft 1112 provided opposite to the limiting protrusions 1111 on both sides and the panel 120, and the hinge shaft 1112 is movably connected to the hinge claw 131 provided at the corresponding end of the panel 120.

[0063] Compared with the technical solution proposed in the first embodiment, the structural arrangement of the present embodiment does not prevent the cover plate 130 from being lost during the process of replacing the lock tongue structure 200 , and the cover plate 130 can be installed quickly.

[0064] Compared with the technical solution proposed in the second embodiment, the structural setting of this embodiment can prevent the cover plate 130 from fatigue fracture after repeated bending. At the same time, if the cover plate 130 is damaged, only part of the cover plate 130 needs to be replaced, which is more cost-effective.

[0065] In summary, the panel 120 provided by the present application is integrally formed with the base and does not require screws to fix, thereby overcoming the problems of the panel 120 being offset, the lock hole being loose, etc. caused by the panel 120 screws being loose or falling off in the prior art, and prolonging the service life of the door lock.
