Abstract
Description
Technical Field
[0001] This utility model relates to the field of locks, specifically to a main bolt transmission structure for a lock body and a lock body. Background Technology
[0002] The lock body is an important structure of a lock. Inside the lock body is a handle rotating component that connects to the handle. When the handle inside the door is turned, this handle rotating component drives the main bolt of the lock body to retract into the lock shell. Most modern lock bodies do not have a reverse lifting mechanism (where the handle inside the door rotates upward to drive the main bolt out of the lock shell). The few lock bodies with a reverse lifting mechanism have a more complex transmission structure. Utility Model Content
[0003] This utility model addresses the above-mentioned problems by proposing a main lock tongue transmission structure and a lock body.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A main bolt drive structure for a lock body, the lock body including a lock shell, the main bolt drive structure comprising:
[0006] The main bolt is slidably mounted on the lock housing, and the main bolt has a first mating part;
[0007] The main bolt lever is rotatably mounted on the lock housing. The main bolt lever has a second mating part that engages with the first mating part. When the main bolt lever rotates, it can drive the main bolt to slide.
[0008] The first handle rotating component is rotatably mounted on the lock housing and is used to connect to one of the handles of the lock.
[0009] An opening plate, movably mounted on the lock housing, has one end engaging with a first handle rotating component and the other end engaging with a main bolt lever. When the first handle rotating component rotates around direction A, it engages with the opening plate, driving the opening plate to move. The opening plate then rotates the main bolt lever, causing the main bolt to retract into the lock housing.
[0010] The deadbolt plate is movably mounted on the lock housing. One end of the deadbolt plate is used to cooperate with the first handle rotating component, and the other end is used to cooperate with the main bolt lever. When the first handle rotating component rotates around direction B, the first handle rotating component cooperates with the deadbolt plate to drive the deadbolt plate to move. The deadbolt plate can drive the main bolt lever to rotate, so that the main bolt extends out of the lock housing. Directions A and B are opposite.
[0011] In this application, direction A and direction B are opposite, meaning one is clockwise and the other is counterclockwise.
[0012] The first handle rotating component of this application controls the rotation of the main lock tongue block through the opening plate and the anti-locking plate, thereby controlling the sliding of the main lock tongue. This transmission structure is relatively simple, and the anti-locking plate can realize the reverse lifting function.
[0013] The reverse lifting function mentioned in this application refers to the operation of extending the main bolt out of the lock case by lifting the handle connected to the first handle rotating part in the reverse direction (usually by turning the handle upward).
[0014] In practical application, the first handle rotating part is connected to the handle of the lock located on the inside of the door.
[0015] In one embodiment of the present invention, the opening plate is slidably mounted on the lock housing, or the opening plate is rotatably mounted on the lock housing;
[0016] The deadbolt plate is slidably mounted on the lock housing, or the deadbolt plate is rotatably mounted on the lock housing;
[0017] Both the opening plate and the deadbolt plate are located between the main lock tongue block and the first handle rotating component;
[0018] The opening plate and the deadbolt plate are located on both sides of the rotation axis of the main locking tongue block, and the opening plate and the deadbolt plate are located on both sides of the rotation axis of the first handle rotating component.
[0019] In one embodiment of the present invention, one of the first mating part and the second mating part is an inclined groove, and the other is a protrusion extending into the inclined groove.
[0020] This application also discloses a lock body, including a lock shell and the main lock tongue transmission structure of the lock body described above;
[0021] The lock body also includes:
[0022] The second handle rotating component is rotatably mounted on the first handle rotating component. The second handle rotating component is used to connect with another handle of the lock. The second handle rotating component has a locking groove.
[0023] A flexible pin assembly is disposed on the first handle rotating member. The flexible pin assembly has a positioning pin and an elastic element. The positioning pin has an open state and an closed state. The elastic element is used to make the positioning pin move in the open state. When the positioning pin is in the open state, the positioning pin disengages from the locking groove. After the second handle rotating member is subjected to force, it can rotate relative to the first handle rotating member. When the positioning pin is in the closed state, the positioning pin extends into the locking groove of the second handle rotating member. After the second handle rotating member is subjected to force, it can drive the first handle rotating member to rotate synchronously.
[0024] The clutch motor assembly is mounted on the lock housing and is used to cooperate with the positioning pin to switch the positioning pin between the disengaged and engaged states.
[0025] The first and second handle rotating parts are connected to the two handles respectively. Usually, the first handle rotating part is connected to the handle on the inside of the door, and the second handle rotating part is connected to the handle on the inside of the door. In this way, when the positioning pin is in the disengaged state, the rotation of the external handle cannot drive the first handle connecting part to rotate, that is, it cannot open the main lock tongue (to make the main lock tongue retract into the lock shell). Only when the clutch motor assembly is working and the positioning pin is in the engaged state, the second handle rotating part can be forced to drive the first handle rotating part to rotate synchronously and open the main lock tongue.
[0026] In one embodiment of the present invention, the first handle rotating member has a first mounting hole;
[0027] The lock body also includes a mating part that can be detachably mounted on the first mounting hole; the second handle rotating part has a protrusion.
[0028] When the mating part is installed on the first mounting hole of the first handle rotating part, the protrusion of the second handle rotating part can engage with the mating part. When the positioning pin is in the off state, when the second handle rotating part rotates in one direction, it can rotate relative to the first handle rotating part. When the second handle rotating part rotates in another direction, it can drive the first handle rotating part to rotate in direction B through the engagement of the protrusion and the mating part, so that the first handle rotating part engages with the anti-lock plate, driving the anti-lock plate to move. The anti-lock plate can drive the main lock tongue to rotate, so that the main lock tongue extends out of the lock case.
[0029] In existing lock bodies, the handle located on the outside of the door cannot achieve the reverse lifting function. In this application, by providing a mating part that can be detachably installed in the first mounting hole, when the mating part is installed on the first mounting hole of the first handle rotating part, the protrusion of the second handle rotating part can engage with the mating part. When the positioning pin is in the off state, when the second handle rotating part rotates around one direction, it can rotate relative to the first handle rotating part (i.e., in the off state, the main lock tongue cannot be opened). When the second handle rotating part rotates around the other direction, it can drive the first handle rotating part to rotate around direction B through the engagement of the protrusion and the mating part, so that the first handle rotating part engages with the anti-lock plate, driving the anti-lock plate to move. The anti-lock plate can drive the main lock tongue lever to rotate, so that the main lock tongue extends out of the lock shell, thus realizing the function of anti-locking (reverse lifting function) of the handle on the outside of the door.
[0030] In practical applications, the mating parts can be screwed on or inserted into the first mounting hole.
[0031] In one embodiment of the present invention, the first handle rotating member and the second handle rotating member can be installed in opposite directions on the lock housing by 180°.
[0032] In one embodiment of this utility model, the lock body further includes:
[0033] The latch assembly is movably mounted on the lock housing;
[0034] The latch reset elastic element is located inside the lock housing and is used to cooperate with the latch assembly to give the latch assembly a tendency to move towards the outside of the lock housing;
[0035] An anti-plugging device is rotatably mounted on the lock housing. The anti-plugging device has a stop part, a first driven part, and a second driven part. The anti-plugging device has a locked state and an unlocked state. When the latch assembly extends out of the lock housing and the anti-plugging device is in the locked state, the stop part cooperates with the latch assembly and can prevent the latch assembly from moving inward into the lock housing. When the latch assembly extends out of the lock housing and the anti-plugging device is in the unlocked state, the stop part no longer cooperates with the latch assembly, and the latch assembly can move inward into the lock housing after being pressed.
[0036] An anti-insertion reset elastic element is installed inside the lock housing and works in conjunction with the anti-insertion plug to give the anti-insertion plug a rotational tendency to rotate to the locked state.
[0037] A trigger tongue assembly is movably mounted on the lock housing. The trigger tongue assembly has a first driving part. When the trigger tongue assembly extends out of the lock housing, the first driving part cooperates with the first driven part to put the anti-plugging device in the unlocked state.
[0038] A trigger tongue reset elastic element is disposed inside the lock housing and is used to cooperate with the trigger tongue assembly to give the trigger tongue assembly a tendency to move towards the outside of the lock housing. When the trigger tongue assembly is not subjected to external force, the trigger tongue assembly extends out of the lock housing.
[0039] A latching lever is mounted on the first handle rotating component. The latching lever has a second driving part and a third driving part. The second driving part is used to cooperate with the second driven part, and the third driving part is used to cooperate with the latching lever assembly. When the first handle rotating component rotates around direction A, it can drive the latching lever to rotate. The second driving part of the latching lever, through cooperation with the second driven part, causes the anti-plugging device to rotate and be in the unlocked state. The third driving part drives the latching lever assembly to retract into the lock case.
[0040] In the lock body of this application, when the door is closed, the trigger tongue assembly moves inward toward the lock housing. At this time, the first driving part will not drive the first driven part. The anti-insertion plug is rotated to the locked state under the action of the anti-insertion reset elastic element. At this time, the anti-reverse part cooperates with the oblique tongue assembly. The anti-reverse part can prevent the oblique tongue assembly from moving inward toward the lock housing, thereby realizing the anti-insertion function and improving the security of the lock body.
[0041] When the door needs to be opened, the handle connected to the first handle rotating component rotates (usually downwards), which drives the first handle rotating component to rotate, which in turn drives the latch lever to rotate. The second drive part of the latch lever, through cooperation with the second driven part, causes the anti-plugging device to rotate and be in the unlocked state. Then, the third drive part drives the latch assembly to retract into the lock case, thus realizing the door opening operation.
[0042] In one embodiment of the present invention, the main locking tongue block further has a third mating part;
[0043] The lock body also includes:
[0044] The lock cylinder lever is rotatably mounted on the main bolt.
[0045] The transmission component is rotatably disposed within the lock housing. The transmission component has a first transmission part and a second transmission part. The first transmission part is used to cooperate with the lock cylinder lever, and the second transmission part is used to cooperate with the latch lever or the latch assembly.
[0046] The lock cylinder lever is rotatably mounted on the lock housing. The lock cylinder lever engages with the third mating part of the main bolt lever and the lock cylinder plate. When the main bolt extends out of the lock housing, the lock cylinder lever rotates and first engages with the third mating part, driving the main bolt lever to rotate and retract the main bolt into the lock housing. After the lock cylinder lever continues to rotate in the same direction, it engages with the lock cylinder plate, driving the lock cylinder plate to rotate. The lock cylinder plate drives the transmission component to rotate, and the transmission component drives the latch assembly to retract into the lock housing via the latch plate or directly drives the latch assembly to retract into the lock housing.
[0047] The key can be used to open the door by means of the lock cylinder lever, transmission components and lock cylinder lever block.
[0048] In one embodiment of this utility model, the oblique tongue paddle is rotatably mounted on the first handle rotating component, which has a fourth driving part. The fourth driving part cooperates with the oblique tongue paddle. When the first handle rotating component rotates around direction A, the fourth driving part drives the oblique tongue paddle to rotate synchronously.
[0049] In one embodiment of this utility model, the transmission component is rotatably mounted on the main lock tongue block;
[0050] The main locking tongue block has a second mounting hole for mounting a rotating block.
[0051] In practical applications, the extension or retraction of the main locking tongue can be achieved by controlling the rotation of the rotating block.
[0052] The beneficial effects of this utility model are: the first handle rotating component of this application controls the rotation of the main lock tongue block through the opening plate and the anti-locking plate, thereby controlling the sliding of the main lock tongue. This transmission structure is relatively simple, and the anti-locking plate can realize the reverse lifting function. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0075] The present invention will now be described in detail with reference to the accompanying drawings.
[0076] like Figures 1-17 As shown, a lock body is disclosed, including a lock shell 1 and a main lock tongue transmission structure of the lock body. For example... Figures 1-5 As shown, the main locking tongue drive structure includes:
[0077] The main bolt 2 is slidably mounted on the lock housing 1, and the main bolt 2 has a first mating part 21.
[0078] The main lock tongue block 3 is rotatably mounted on the lock housing 1. The main lock tongue block 3 has a second mating part 31, which is mated with the first mating part 21. When the main lock tongue block 3 rotates, it can drive the main lock tongue 2 to slide.
[0079] The first handle rotating part 41 is rotatably mounted on the lock housing 1 and is used to connect with one handle of the lock.
[0080] An opening plate 51 is movably mounted on the lock housing 1. One end of the opening plate 51 engages with the first handle rotating member 41, and the other end engages with the main bolt lever 3. When the first handle rotating member 41 rotates around direction A, the first handle rotating member 41 engages with the opening plate 51, driving the opening plate 51 to move. The opening plate 51 can drive the main bolt lever 3 to rotate, causing the main bolt 2 to retract into the lock housing 1; and
[0081] The deadbolt plate 52 is movably mounted on the lock housing 1. One end of the deadbolt plate 52 is used to cooperate with the first handle rotating member 41, and the other end is used to cooperate with the main bolt lever 3. When the first handle rotating member 41 rotates around direction B, the first handle rotating member 41 cooperates with the deadbolt plate 52, driving the deadbolt plate 52 to move. The deadbolt plate 52 can drive the main bolt lever 3 to rotate, causing the main bolt 2 to extend out of the lock housing 1. Directions A and B are opposite.
[0082] In this application, direction A and direction B are opposite, meaning one is clockwise and the other is counterclockwise. Specifically... Figure 4 and Figure 5 Rotating around direction A means rotating clockwise, and rotating around direction B means rotating counterclockwise.
[0083] The first handle rotating component 41 of this application controls the rotation of the main lock tongue block 3 through the opening plate 51 and the anti-locking plate 52, thereby controlling the sliding of the main lock tongue 2. This transmission structure is relatively simple, and the anti-locking plate 52 can realize the reverse lifting function.
[0084] The reverse lifting function mentioned in this application refers to the operation of extending the main bolt 2 out of the lock case 1 by lifting the handle connected to the first handle rotating part 41 in the reverse direction (usually by rotating the handle upward).
[0085] In actual use, the first handle rotating part 41 is connected to the handle of the lock located on the inside of the door.
[0086] In this embodiment, the opening plate 51 is slidably mounted on the lock housing 1, and the deadbolt plate 52 is slidably mounted on the lock housing 1;
[0087] Both the opening plate 51 and the deadbolt plate 52 are located between the main bolt lever 3 and the first handle rotating part 41;
[0088] The opening plate 51 and the deadbolt plate 52 are located on both sides of the rotation axis of the main lock tongue block 3, and the opening plate 51 and the deadbolt plate 52 are located on both sides of the rotation axis of the first handle rotating member 41.
[0089] In practical applications, it can also be set up as follows: the opening plate 51 is rotatably mounted on the lock housing 1; the deadbolt plate 52 is rotatably mounted on the lock housing 1.
[0090] like Figure 4 and 5 As shown, in this embodiment, one of the first mating part 21 and the second mating part 31 is a groove, and the other is a protrusion extending into the groove.
[0091] like Figures 13-17 As shown, the lock body also includes:
[0092] The second handle rotating part 42 is rotatably mounted on the first handle rotating part 41. The second handle rotating part 42 is used to connect with another handle of the lock. The second handle rotating part 42 has a locking groove 421.
[0093] The elastic pin assembly 43 is disposed on the first handle rotating member 41. The elastic pin assembly 43 has a positioning pin 431 and an elastic element 432. The positioning pin 431 has an open state and an closed state. The elastic element 432 is used to make the positioning pin 431 move in the open state. When the positioning pin 431 is in the open state, the positioning pin 431 is disengaged from the locking groove 421. After the second handle rotating member 42 is subjected to force, it can rotate relative to the first handle rotating member 41. When the positioning pin 431 is in the closed state, the positioning pin 431 extends into the locking groove 421 of the second handle rotating member 42. After the second handle rotating member 42 is subjected to force, it can drive the first handle rotating member 41 to rotate synchronously.
[0094] The clutch motor assembly 44 is mounted on the lock housing 1 and is used to cooperate with the positioning pin 431 to switch the positioning pin 431 between the disengaged state and the engaged state.
[0095] The first handle rotating component 41 and the second handle rotating component 42 are respectively connected to two handles. Usually, the first handle rotating component 41 is connected to the handle on the inside of the door, and the second handle rotating component 42 is connected to the handle on the inside of the door. In this way, when the positioning pin 431 is in the disengaged state, the rotation of the external handle cannot drive the first handle connecting component to rotate, that is, it cannot open the main lock tongue 2 (to retract the main lock tongue 2 into the lock shell 1). Only when the clutch motor assembly 44 is working and the positioning pin 431 is in the engaged state, the second handle rotating component 42 can drive the first handle rotating component 41 to rotate synchronously after being subjected to force, thus opening the main lock tongue 2.
[0096] like Figures 13-17 As shown, in this embodiment, the first handle rotating member 41 has a first mounting hole 411;
[0097] The lock body also includes a mating part 412 that is detachably mounted on the first mounting hole 411; the second handle rotating part 42 has a protrusion 422;
[0098] When the mating part 412 is installed on the first mounting hole 411 of the first handle rotating part 41, the protrusion 422 of the second handle rotating part 42 can engage with the mating part 412. When the positioning pin 431 is in the off state, when the second handle rotating part 42 rotates in one direction, it can rotate relative to the first handle rotating part 41. When the second handle rotating part 42 rotates in another direction, it can drive the first handle rotating part 41 to rotate in direction B through the engagement of the protrusion 422 and the mating part 412, so that the first handle rotating part 41 engages with the deadbolt plate 52, driving the deadbolt plate 52 to move. The deadbolt plate 52 can drive the main lock tongue block 3 to rotate, so that the main lock tongue 2 extends out of the lock case 1.
[0099] In existing lock bodies, the handle located on the outside of the door cannot achieve the reverse lifting function. In this application, by providing a mating part 412 that can be detachably installed in the first mounting hole 411, when the mating part 412 is installed on the first mounting hole 411 of the first handle rotating part 41, the protrusion 422 of the second handle rotating part 42 can cooperate with the mating part 412. When the positioning pin 431 is in the off state, when the second handle rotating part 42 rotates around one direction, it can rotate relative to the first handle rotating part 41 (that is, in the off state, the main lock tongue 2 cannot be opened). When the second handle rotating part 42 rotates around the other direction, it can drive the first handle rotating part 41 to rotate around direction B through the cooperation of the protrusion 422 and the mating part 412, so that the first handle rotating part 41 cooperates with the deadbolt plate 52, driving the deadbolt plate 52 to move. The deadbolt plate 52 can drive the main lock tongue lever 3 to rotate, so that the main lock tongue 2 extends out of the lock shell 1, thus realizing the function of deadbolting (reverse lifting function) of the handle on the outside of the door.
[0100] In practical applications, the mating part 412 can be screwed onto or inserted into the first mounting hole 411.
[0101] like Figure 13 , 14 As shown in Figure 17, in this embodiment, the first handle rotating member 41 and the second handle rotating member 42 can be installed in a 180° reversible manner on the lock housing 1.
[0102] like Figures 6-12 As shown, in this embodiment, the lock body further includes:
[0103] The latch assembly 61 is movably mounted on the lock housing 1;
[0104] The latch reset elastic element 62 is disposed inside the lock housing 1 and is used to cooperate with the latch assembly 61 to give the latch assembly 61 a tendency to move towards the outside of the lock housing 1.
[0105] Anti-plug 63 is rotatably mounted on the lock housing 1. Anti-plug 63 has a stop part 631, a first driven part 632, and a second driven part 633. Anti-plug 63 has a locked state and an unlocked state. When the latch assembly 61 extends out of the lock housing 1 and the anti-plug 63 is in the locked state, the stop part 631 cooperates with the latch assembly 61 and can prevent the latch assembly 61 from moving inward to the lock housing 1. When the latch assembly 61 extends out of the lock housing 1 and the anti-plug 63 is in the unlocked state, the stop part 631 no longer cooperates with the latch assembly 61, and the latch assembly 61 can move inward to the lock housing 1 after being pressed.
[0106] The anti-insertion reset elastic element 64 is disposed inside the lock housing 1 and cooperates with the anti-insertion plug 63 to give the anti-insertion plug 63 a rotational tendency to rotate to the locked state.
[0107] The trigger tongue assembly 65 is movably mounted on the lock housing 1. The trigger tongue assembly 65 has a first driving part 651. When the trigger tongue assembly 65 extends out of the lock housing 1, the first driving part 651 cooperates with the first driven part 632 to make the anti-plug 63 in the unlocked state.
[0108] The trigger tongue reset elastic element 66 is disposed inside the lock housing 1 and is used to cooperate with the trigger tongue assembly 65 to give the trigger tongue assembly 65 a tendency to move towards the outside of the lock housing 1. When the trigger tongue assembly 65 is not subjected to external force, the trigger tongue assembly 65 extends out of the lock housing 1.
[0109] The latch lever 67 is mounted on the first handle rotating member 41. The latch lever 67 has a second driving part 671 and a third driving part 672. The second driving part 671 is used to cooperate with the second driven part 633, and the third driving part 672 is used to cooperate with the latch assembly 61. When the first handle rotating member 41 rotates around direction A, it can drive the latch lever 67 to rotate. The second driving part 671 of the latch lever 67, through cooperation with the second driven part 633, causes the anti-plug 63 to rotate and be in the unlocked state. The third driving part 672 drives the latch assembly 61 to retract into the lock case 1.
[0110] In the closed state, the trigger tongue assembly 65 of the lock body of this application moves inward toward the lock housing 1. At this time, the first driving part 651 will not drive the first driven part 632. The anti-insertion plug 63 rotates to the locked state under the action of the anti-insertion reset elastic member 64. At this time, the anti-reverse part 631 cooperates with the oblique tongue assembly 61. The anti-reverse part 631 can prevent the oblique tongue assembly 61 from moving inward toward the lock housing 1, thereby realizing the anti-insertion function and improving the security of the lock body.
[0111] When the door needs to be opened, the handle connected to the first handle rotating component 41 rotates (usually downwards), causing the first handle rotating component 41 to rotate, which in turn causes the latch plate 67 to rotate. The second drive part 671 of the latch plate 67, through cooperation with the second driven part 633, causes the anti-plug 63 to rotate and be in the unlocked state. Then, the third drive part 672 drives the latch assembly 61 to retract into the lock case 1, realizing the door opening operation.
[0112] like Figure 6 and 10 As shown, in this embodiment, the main locking tongue block 3 also has a third mating part 32;

The first transmission part 81 is used to cooperate with the lock cylinder lever 7, and the second transmission part 82 is used to cooperate with the latch lever 67 or the latch assembly 61.
[0116] Lock cylinder lever 9 is rotatably mounted on lock housing 1. Lock cylinder lever 9 is used to cooperate with the third mating part 32 of main bolt lever 3 and lock cylinder lever 7. When the main bolt 2 extends out of lock housing 1, lock cylinder lever 9 rotates and first cooperates with the third mating part 32, driving the main bolt lever 3 to rotate, causing the main bolt 2 to retract into lock housing 1. After the lock cylinder lever 9 continues to rotate in the same direction, it cooperates with lock cylinder lever 7, driving lock cylinder lever 7 to rotate. Lock cylinder lever 7 drives transmission component 8 to rotate. Transmission component 8 drives the oblique bolt assembly 61 to retract into lock housing 1 through oblique bolt lever 67 or directly drives the oblique bolt assembly 61 to retract into lock housing 1.
[0117] The key-operated door opening operation can be achieved through the lock cylinder lever 7, the transmission component 8, and the lock cylinder lever 9.
[0118] like Figure 6 As shown, in this embodiment, the oblique tongue paddle 67 is rotatably mounted on the first handle rotating member 41. The first handle rotating member 41 has a fourth driving part 413. The fourth driving part 413 cooperates with the oblique tongue paddle 67. When the first handle rotating member 41 rotates around direction A, the oblique tongue paddle 67 is driven to rotate synchronously through the fourth driving part 413.
[0119] like Figure 5 As shown, in this embodiment, the transmission component 8 is rotatably mounted on the main lock tongue block 3;
[0120] like Figure 6 As shown, the main latch block 3 has a second mounting hole 33 for mounting a rotating block. In actual use, the extension or retraction of the main latch 2 can be achieved by controlling the rotation of the rotating block.
