TECHNICAL FIELD
[0001] The present scheme relates to the field of locks, in particular to a light-weight lock structure. BACKGROUND
[0002] The door lock is installed on the door to protect the privacy and safety of the residents. Its basic structure includes a retractable lock tongue that cooperates with the lock catch box or lock catch sheet installed on the door frame to prevent the door from being opened by wind and other accidental conditions. The common lock has a lock cylinder. Due to the characteristics of the lock tongue structure, the one-way lock cylinder cannot meet the needs of all occasions during installation. When a lock is equipped with two lock cylinders, it can meet the needs of different scenes, but the disadvantage is that the structure is too heavy, and it is very laborious to move multiple locks.
[0003] Therefore, a lock structure is needed that can be equipped with two lock cylinders while having the characteristics of light weight. SUMMARY

[0006] The handle linkage plate is a single-layer structure, and the dead tongue end is a concave structure.
[0007] Further, the lock tongue mechanism, the lock tongue is connected to the lock tongue plate; the first linkage plate and the limiting column limit the maximum stroke of the lock tongue plate.
[0008] Further, the lock tongue plate is stacked with the dead tongue mechanism above, the first concave part on both sides of the plate surface limits one end of the first linkage plate, and the second concave part at the bottom is provided with a limiting column to limit the maximum stroke of the second concave part.
[0009] Further, the dead tongue mechanism includes a dead tongue plate and a limiting plate, and the dead tongue plate and the limiting plate 42 are stacked and limited by the limiting column.
[0010] Further, the dead tongue plate includes a dead tongue end, a first through hole, a second through hole, and a third concave part, the first through hole is sleeved outside the limiting column, the second through hole limits the limiting plate, and the third concave part is used for limiting the rotating end of the limiting lock cylinder.
[0011] Further, the limiting plate is axisymmetric, the first protrusion slides in the second through hole, the back of the first protrusion includes a second protrusion, the second protrusion is limited in the second linkage plate, a third through hole is sleeved outside the limiting column, and a limiting end is included below the third through hole.
[0012] Furthermore, the limiting end is low in the middle and high on both sides, so the first protrusion can only slide from both sides into the fourth through hole below the limiting end.
[0013] Furthermore, the housing includes a base and a cover plate;
[0014] The base has internal threads on its fixing post, which, together with screws, secures the base and the cover plate.
[0015] Furthermore, in the panel, second outlets are symmetrically distributed on both sides of the first outlet, the first outlet is used to pass through the locking tongue plate, and the second outlet is used to pass through the deadbolt plate.
[0016] In summary, this solution has the following advantages:
[0017] The latch provided in this solution has a recessed structure. The properties of its metal material ensure that the recessed structure can meet the anti-theft function. At the same time, the recessed structure reduces the amount of material used and the overall weight of the lock.
[0018] The handle linkage plate provided in this solution is designed as a single-layer plate, which makes the structure thinner and lighter, thus achieving the effects of weight reduction and material saving. Attached Figure Description

[0035] The present application will be further described below in conjunction with the accompanying drawings and examples:
[0036] Example 1:
[0037] A light weight lock structure, as shown, comprising a housing 1 connected to a panel 2, a bolt mechanism 3 and a dead bolt mechanism 4 limited in the housing 1, a handle linkage plate 111 limiting the handle and driving the bolt mechanism 3 in and out of the housing 1, a lock cylinder limited in the housing 1, and when rotated, driving the bolt mechanism 3 and the dead bolt mechanism 4 in and out of the housing 1.
[0038] The housing 1 comprises a base 11 and a cover plate 12, the base 11 is connected to the panel 2 around a long edge, and the panel 2 and the remaining three edges of the base 11 and the top cover form the inner cavity of the lock body. The protrusions and through holes in the base 11 are symmetrically arranged for limiting the bolt mechanism 3, the dead bolt mechanism 4 and the lock cylinder.
[0039] The fixed column 112 inside the base 11 has internal threads, and the fixed column 112 fixes the base 11 and the cover plate 12 by combining with a screw.
[0040] The cover plate 12 comprises a mounting hole 121, a handle connecting hole 122 and a lock cylinder connecting hole 123, and the mounting hole 121 corresponds to the fixed column 112.
[0041] The panel 2, the second outlet 22 is symmetrically distributed on both sides of the first outlet 21, the first outlet 21 is used through the lock tongue plate 32, and the second outlet 22 is used through the dead tongue plate 41.
[0042] The lock tongue mechanism 3, the lock tongue 31 is a latch structure; the lock tongue 31 is connected at the top of the lock tongue plate 32, the first recess 321 on both sides of the lock tongue plate 32 limits one end of the first linkage plate 33, the first linkage plate 33 drives the lock tongue plate 32 to reciprocate in the first recess 321 and limits the maximum stroke of the lock tongue plate 32 advancing; the second recess 322 at the bottom of the lock tongue plate 32 is provided with a limiting column 113 beside, which limits the maximum stroke of the second recess 322 retreating.
[0043] The dead tongue mechanism 4 includes a dead tongue plate 41 and a limiting plate 42, and the dead tongue plate 41 and the limiting plate 42 are stacked on the lock tongue plate 32 and limited by the limiting column 113.
[0044] The dead tongue plate 41 is axisymmetric and includes a dead tongue end 411, a first through hole 412, a second through hole 413 and a third recess 414, the top is the dead tongue end 411, the first through hole 412 is sleeved outside the limiting column 113, the second through hole 413 limits the limiting plate 42, and the third recess 414 is used for limiting the rotating end of the limiting lock cylinder.
[0045] The dead tongue end 411 provided by the scheme is a recess structure, and the special properties of the metal material can ensure that the recess structure can meet the anti-theft function, and at the same time, the recess structure reduces the use of materials and the overall weight of the lock.
[0046] The limiting plate 42 is axisymmetric and includes a first convex point 421 on the contact surface of the dead tongue plate 41, the first convex point 421 slides in the second through hole 413, the first convex point 421 includes a second convex point 422 on the back, the second convex point 422 is limited in the second linkage plate 5, a third through hole 423 is sleeved outside the limiting column 113, a limiting end 424 is included below the third through hole 423, the limiting end 424 is low in the middle and high on both sides, when the first convex point 421 slides to the middle of the third through hole 423, the first convex point 421 is limited by the protruding part of the limiting end 424 and cannot move downward, when the first convex point 421 slides to both sides of the third through hole 423, the first convex point 421 can reach the fourth through hole 425 through the limiting end 424.
[0047] The limiting plate 42 is fixed on the elastic sheet 43 in the shell 1, and the elastic sheet 43 is used for resetting the limiting plate 42.
[0048] Specifically, when the rotating end of the lock cylinder protrudes and is limited in the third recess 414, the limiting plate 42 is pushed away, at this time, the first convex point 421 slides to one side of the third through hole 423, and the spring 1112 sheet is in a tense state under the external force;
[0049] Rotating the protruding end of the lock cylinder causes the third recess 414 to move upward, at which point the latch plate 41 extends out of the housing 1;
[0050] When the rotating end of the lock cylinder retracts, the external force received by the spring 1112 disappears, and the spring 1112 drives the limiting plate 42 to reset. After resetting, when the first protrusion 421 slides to the middle of the third through hole 423, it is limited by the protruding part of the limiting end 424 and cannot move downward.
[0051] The second linkage plate 5 is stacked on the limiting plate 42. The fifth through hole 51 on the surface of the second linkage plate 5 is fitted outside the second protrusion 422. The lower protrusion 52 is driven to move during the rotation of the rotating end of the lock cylinder. The bottom baffle 53, driven by the handle linkage plate 111, pushes the first linkage plate 33 to drive the lock tongue plate 32 to retract inward.
[0052] Compared with the prior art, the handle linkage plate 111 is designed as a single-layer plate, which makes its structure thinner and lighter, thus achieving the effects of weight reduction and material saving.
[0053] The handle linkage plate 111 and the base 11 have side limiting springs 1112, the springs 1112 being reset springs 1112, used for resetting the handle linkage plate 111.
[0054] Further explanation based on its usage mechanism:
[0055] 1. Initial state
[0056] In the initial state, the locking tongue 31 protrudes from the housing 1, while the latch is retracted inside the housing 1.
[0057] 2. Use the handle to open the door.
[0058] When the handle is turned, the baffle 53 of the second linkage plate 5 is driven by the handle linkage plate 111, which pushes the first linkage plate 33 to drive the latch plate 32 to retract inward, the latch 31 is retracted, and the door is opened; when the handle is released, the spring 1112 drives the handle linkage plate 111 to return to its original position.
[0059] 3. Lock using the lock cylinder
[0060] When the rotating end of the lock cylinder protrudes and is limited within the third recess 414, the limiting plate 42 is pushed. At this time, the first protrusion 421 slides to one side of the third through hole 423, and the spring 1112 is under tension due to external force. The protruding end of the lock cylinder is rotated, which drives the third recess 414 to move upward. At this time, the latch plate 41 extends outward from the housing 1. When the rotating end of the lock cylinder is retracted, the external force received by the spring 1112 disappears, and the spring 1112 drives the limiting plate 42 to reset. After resetting, when the first protrusion 421 slides to the middle of the third through hole 423, it is limited by the protruding part of the limiting end 424 and cannot move downward, thus locking the door.
[0061] 4. Unlocking using the lock cylinder
[0062] According to the unlocking steps of the lock cylinder, the rotating end is rotated in the opposite direction, and when the dead bolt plate 41 is reset, the rotating end of the lock cylinder is rotated again, the second linkage plate 5 is moved through the linkage protrusion 52, and the lock bolt plate 32 is driven inwardly, and the door can be directly opened after unlocking.
[0063] In summary, the dead bolt end of the present application is a concave structure, and the metal material can ensure that the concave structure can meet the anti-theft function, and the concave structure reduces the use of materials and the weight of the lock.
[0064] The handle linkage plate of the present application is provided as a single-layer plate, which is more light and thin, and plays a role in lightweight and material saving.
