Description

Technical Field

[0001] The present invention relates to the field of locks, and in particular to a two-way flip locking mechanism and a lock body. Background Art

[0002] The lock body includes a beveled tongue with a beveled surface. The beveled tongue with a single beveled surface is directional. Therefore, if it needs to be installed in the opposite direction during actual installation, it is usually necessary to disassemble the lock body, replace the beveled tongue or rotate the beveled tongue 180°, which makes the installation more cumbersome. Summary of the Invention

[0003] In response to the above problems, the present invention proposes a two-way flip locking mechanism and a lock body.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A two-way flip locking mechanism, comprising:

[0006] Lock case;

[0007] An inclined tongue plate is slidably arranged on the lock housing;

[0008] A latch bolt is rotatably mounted on the latch bolt plate and is capable of rotating about a first rotation axis. The latch bolt has a first working surface and a second working surface, the first working surface and the second working surface are arranged obliquely and are respectively located on both sides of the latch bolt. The latch bolt further has a first chute and a second chute, the first chute is arranged obliquely with respect to the second working surface, and the second chute is arranged obliquely with respect to the first working surface.

[0009] An elastic member for resetting the inclined tongue plate, one end of which cooperates with the inclined tongue or the inclined tongue plate to make the inclined tongue and the inclined tongue plate have a movement tendency to move toward the outside of the lock housing;

[0010] A locking block is movably provided on the lock housing, and the locking block is used to slidably cooperate with the first sliding groove or the second sliding groove. When the locking block cooperates with the first sliding groove, the inclined tongue cannot rotate relative to the inclined tongue plate, and the inclined tongue and the inclined tongue plate can only slide along the length direction of the first sliding groove. At this time, the second working surface is inclined relative to the sliding direction of the inclined tongue; when the locking block cooperates with the second sliding groove, the inclined tongue cannot rotate relative to the inclined tongue plate, and the inclined tongue and the inclined tongue plate can only slide along the length direction of the second sliding groove. At this time, the first working surface is inclined relative to the sliding direction of the inclined tongue;

[0011] The locking block reset elastic member is used to directly or indirectly cooperate with the locking block to keep the locking block in a state of sliding cooperation with the first sliding groove or the second sliding groove.

[0012] The inclined bolt can be rotated to achieve switching between two installation directions. When the inclined bolt is used for the first installation direction, the first slide groove cooperates with the locking block, and the inclined bolt can only slide along the length direction of the first slide groove. At this time, the second working surface is inclined relative to the door frame. When the door is closed, the second working surface cooperates with the door frame. Under the reaction force of the door frame, the inclined bolt can slide along the length direction of the first slide groove and retract the lock body; when the inclined bolt is used for the second installation direction (at this time the position of the inclined bolt has rotated relative to when it is used as the first installation position), the second slide groove can cooperate with the corresponding structure in the lock body, and the inclined bolt can only slide along the length direction of the second slide groove. At this time, the first working surface is inclined relative to the door frame. When the door is closed, the first working surface cooperates with the door frame. Under the reaction force of the door frame, the inclined bolt can slide along the length direction of the second slide groove and retract the lock body.

[0013] The present application uses a rotatable inclined tongue, combined with a locking block and the first working surface, second working surface, first slide groove and second slide groove of the inclined tongue, to achieve convenient switching between two installation directions without removing or replacing the inclined tongue.

[0014] In actual use, the action of driving the locking block to move so as to disengage the locking block from the first chute or the second chute can be achieved by a mechanism in the lock housing or by human operation.

[0015] In the present application, the first rotation axis refers to the axis of the rotation shaft between the inclined tongue and the inclined tongue plate.

[0016] In actual use, the locking block can be slidably or rotatably arranged on the lock body.

[0017] In one embodiment of the present invention, the lock housing has an adjustment opening corresponding to the locking block, or the locking block has an adjustment portion extending out of the lock housing.

[0018] In actual use, the position of the locking block can be adjusted by hand or with a tool through the adjustment interface to switch the installation direction of the latch bolt. The design of the adjustment portion allows a person to directly drive the locking block through the adjustment portion to switch the installation direction of the latch bolt.

[0019] That is, the locking block can be unlocked by adjusting the mouth adjustment part, and the oblique tongue can be rotated at this time. After rotating to the other direction, it is released. Under the action of the locking block reset elastic member, the locking block cooperates with the corresponding sliding groove.

[0020] In one embodiment of the present invention, the device further includes a trigger tongue assembly and a trigger tongue resetting elastic member. The trigger tongue assembly is movably disposed on the lock housing and can extend out of and retract into the lock housing. The trigger tongue resetting elastic member cooperates with the trigger tongue assembly to cause the trigger tongue assembly to have a movement tendency to extend out of the lock housing.

[0021] The trigger tongue assembly includes an unlocking portion. When the trigger tongue assembly extends out of the lock housing, the unlocking portion applies a force to the locking block, overcoming the force of the locking block reset elastic member, so that the locking block moves and disengages from the first sliding groove or the second sliding groove. At this time, the locking block can rotate relative to the inclined tongue plate; when the trigger tongue assembly retracts into the lock housing, the unlocking portion does not apply a force to the locking block, and the locking block moves under the action of the locking block reset elastic member and cooperates with the corresponding sliding groove.

[0022] This arrangement, through the cooperation of the trigger tongue assembly and the locking block's return spring, automatically drives the locking block, eliminating the need for manual adjustment. Regardless of the orientation of the door, when the trigger tongue assembly extends from the lock housing before closing the door, the locking block disengages the first or second chute, and the bolt automatically rotates and switches due to the reaction force of the door frame. When the trigger tongue assembly retracts into the lock housing, the locking block's return spring engages the corresponding chute, locking the latch bolt (preventing it from rotating).

[0023] In actual use, the trigger tongue assembly may include a trigger tongue and a tongue frame. The trigger tongue may be rotatably mounted on the tongue frame.

[0024] In one embodiment of the present invention, the locking block is rotatably mounted on the lock housing, and the locking block has a first limiting strip and a pressure-bearing portion, wherein the first limiting strip is configured to cooperate with the first sliding groove or the second sliding groove;

[0025] The unlocking portion cooperates with the pressed portion, and when the trigger tongue assembly extends out of the lock housing, the unlocking portion drives the locking block to rotate through the pressed portion.

[0026] The cooperation between the pressure-bearing part and the unlocking part also plays a role in noise reduction to a certain extent, preventing the trigger tongue assembly from directly hitting the lock housing at a high speed.

[0027] In one embodiment of the present invention, the lock housing has a limit seat, the inclined tongue plate has a limit portion that cooperates with the limit seat and limits the maximum distance the inclined tongue plate can move outward, and a buffer pad is provided between the limit seat and the limit portion.

[0028] The design of the cushion reduces noise.

[0029] In one embodiment of the present invention, the first rotation axis is parallel to the first working surface and the second working surface.

[0030] In one embodiment of the present invention, a symmetry plane is defined between the first working surface and the second working surface, the first working surface and the second working surface are symmetrically arranged with respect to the symmetry plane, and the first rotation axis is located on the symmetry plane;

[0031] The first sliding groove and the second sliding groove are symmetrical with respect to the symmetry plane.

[0032] In one embodiment of the present invention, the first chute is arranged parallel to the first working surface, and the second chute is arranged parallel to the second working surface;

[0033] The length direction of the first sliding groove is perpendicular to the first rotation axis, and the length direction of the second sliding groove is perpendicular to the first rotation axis.

[0034] This application also discloses another bidirectional flip locking mechanism, comprising:

[0035] Lock case;

[0036] An inclined tongue plate is slidably arranged on the lock housing;

[0037] The inclined tongue is rotatably mounted on the inclined tongue plate and is capable of rotating about a first rotation axis. The inclined tongue has a first rotation axis. The inclined tongue has a first working surface and a second working surface. The first working surface and the second working surface are arranged obliquely and are respectively located on both sides of the inclined tongue. The inclined tongue further has a first chute and a second chute. The first chute is arranged obliquely with respect to the second working surface, and the second chute is arranged obliquely with respect to the first working surface.

[0038] An elastic member for resetting the inclined tongue plate, one end of which cooperates with the inclined tongue or the inclined tongue plate to make the inclined tongue and the inclined tongue plate have a movement tendency to move toward the outside of the lock housing;

[0039] A locking block is movably provided on the lock housing, and the locking block is used to slidably cooperate with the first sliding groove or the second sliding groove. When the locking block cooperates with the first sliding groove, the inclined tongue cannot rotate relative to the inclined tongue plate, and the inclined tongue and the inclined tongue plate can only slide along the length direction of the first sliding groove. At this time, the second working surface is inclined relative to the sliding direction of the inclined tongue; when the locking block cooperates with the second sliding groove, the inclined tongue cannot rotate relative to the inclined tongue plate, and the inclined tongue and the inclined tongue plate can only slide along the length direction of the second sliding groove. At this time, the first working surface is inclined relative to the sliding direction of the inclined tongue;

[0040] The trigger tongue assembly is movably provided on the lock housing and can extend out of the lock housing and retract into the lock housing. The trigger tongue assembly has an unlocking portion, which is used to cooperate with the locking block. When the trigger tongue assembly extends out of the lock housing, the unlocking portion applies a force to the locking block to move the locking block and disengage the first sliding groove or the second sliding groove. At this time, the locking block can rotate relative to the inclined tongue plate; when the trigger tongue assembly retracts the lock housing, the unlocking portion drives the locking block to move so that the locking block moves toward the corresponding sliding groove.

[0041] The trigger tongue resetting elastic member cooperates with the trigger tongue assembly to enable the trigger tongue assembly to have a movement tendency of extending out of the lock housing.

[0042] That is, the trigger tongue assembly is linked to the locking block, and the locking block is completely driven by the trigger tongue assembly. In actual use, the trigger tongue assembly and the locking block can be realized by the cooperation of the driving groove and the driving protrusion.

[0043] The present application also discloses a lock body, comprising the bidirectional flip locking mechanism described above.

[0044] The beneficial effect of the present invention is that the present application uses a rotatable inclined tongue, combined with a locking block and the first working surface, second working surface, first slide groove and second slide groove of the inclined tongue, to realize switching between two installation directions more conveniently without removing or replacing the inclined tongue.

[0057] The present invention will be described in detail below with reference to the accompanying drawings.

[0058] Example 1

[0059] like Figures 1 to 7 As shown, a two-way flip locking mechanism includes:

[0060] Lock housing 7;

[0061] The inclined tongue plate 2 is slidably arranged on the lock housing 7;

[0062] The latch bolt 1 is rotatably mounted on the latch bolt plate 2 and is capable of rotating about a first rotation axis 100. The latch bolt 1 has a first working surface 11 and a second working surface 12. The first working surface 11 and the second working surface 12 are arranged at an angle and are respectively located on either side of the latch bolt 1. The latch bolt 1 also has a first chute 13 and a second chute 14. The first chute 13 is arranged at an angle to the second working surface 12, and the second chute 14 is arranged at an angle to the first working surface 11.

[0063] The latch plate reset elastic member 5, one end of which cooperates with the latch 1 or the latch plate 2 to make the latch 1 and the latch plate 2 have a movement tendency to move toward the outside of the lock housing 7;

[0064] The locking block 3 is movably provided on the lock housing 7. The locking block 3 is used to slidably cooperate with the first sliding groove 13 or the second sliding groove 14. When the locking block 3 cooperates with the first sliding groove 13, the inclined tongue 1 cannot rotate relative to the inclined tongue plate 2. The inclined tongue 1 and the inclined tongue plate 2 can only slide along the length direction of the first sliding groove 13. At this time, the second working surface 12 is tilted relative to the sliding direction of the inclined tongue 1. When the locking block 3 cooperates with the second sliding groove 14, the inclined tongue 1 cannot rotate relative to the inclined tongue plate 2. The inclined tongue 1 and the inclined tongue plate 2 can only slide along the length direction of the second sliding groove 14. At this time, the first working surface 11 is tilted relative to the sliding direction of the inclined tongue 1.

[0065] The locking block reset elastic member 4 is used to directly or indirectly cooperate with the locking block 3 to keep the locking block 3 in a sliding cooperation state with the first sliding groove 13 or the second sliding groove 14 .

[0066] The latch bolt 1 can rotate to achieve switching between two installation directions. When the latch bolt 1 is used for the first installation direction, the first slide groove 13 cooperates with the locking block 3, and the latch bolt 1 can only slide along the length direction of the first slide groove 13. At this time, the second working surface 12 is inclined relative to the door frame. When the door is closed, the second working surface 12 cooperates with the door frame. Under the reaction force of the door frame, the latch bolt 1 can slide along the length direction of the first slide groove 13 and retract the lock body; when the latch bolt 1 is used for the second installation direction (at this time, the position of the latch bolt 1 has rotated relative to when it is used as the first installation position), the second slide groove 14 can cooperate with the corresponding structure in the lock body, and the latch bolt 1 can only slide along the length direction of the second slide groove 14. At this time, the first working surface 11 is inclined relative to the door frame. When the door is closed, the first working surface 11 cooperates with the door frame. Under the reaction force of the door frame, the latch bolt 1 can slide along the length direction of the second slide groove 14 and retract the lock body.

[0067] The present application uses a rotatable latch bolt 1, combined with a locking block 3 and the first working surface 11, the second working surface 12, the first slide groove 13 and the second slide groove 14 of the latch bolt 1, to achieve convenient switching between two installation directions without removing or replacing the latch bolt 1.

[0068] In actual use, the action of driving the locking block 3 to move so as to disengage the locking block 3 from the first sliding groove 13 or the second sliding groove 14 can be achieved by a mechanism in the lock housing 7 or by human operation.

[0069] In the present application, the first rotation axis 100 refers to the axis of the rotation shaft 6 between the latch bolt 1 and the latch bolt plate 2 .

[0070] In actual use, the locking block 3 can be slidably or rotatably arranged on the lock body.

[0071] In other embodiments, the lock housing 7 has an adjustment opening corresponding to the locking block 3 , or the locking block 3 has an adjustment portion extending out of the lock housing 7 .

[0072] In actual use, the position of the locking block 3 can be adjusted manually or with a tool through the adjustment interface, thereby switching the installation direction of the latch bolt 1. The design of the adjustment portion allows for convenient movement of the locking block 3, thereby switching the installation direction of the latch bolt 1. Specifically, by adjusting the adjustment portion, the locking block 3 can be unlocked, allowing the latch bolt 1 to rotate. After rotating to the other direction, it is released, and the locking block 3 engages with the corresponding slide groove under the action of the locking block's return spring 4.

[0073] like Figures 1 to 4 As shown, in this embodiment, it also includes a trigger tongue assembly 8 and a trigger tongue reset elastic member 9. The trigger tongue assembly 8 is movably arranged on the lock housing 7 and can extend out of the lock housing 7 and retract into the lock housing 7. The trigger tongue reset elastic member 9 cooperates with the trigger tongue assembly 8 to enable the trigger tongue assembly 8 to have a movement tendency of extending out of the lock housing 7.

[0074] The trigger tongue assembly 8 has an unlocking portion 821. When the trigger tongue assembly 8 extends out of the lock housing 7, the unlocking portion 821 applies a force to the locking block 3, overcoming the force of the locking block reset elastic member 4, so that the locking block 3 moves and disengages from the first slide groove 13 or the second slide groove 14. At this time, the locking block 3 can rotate relative to the inclined tongue plate 2; when the trigger tongue assembly 8 retracts into the lock housing 7, the unlocking portion 821 does not apply a force to the locking block 3. The locking block 3 moves under the action of the locking block reset elastic member 4 and cooperates with the corresponding slide groove.

[0075] This arrangement, through the cooperation of the trigger tongue assembly 8 and the locking block reset spring 4, automatically drives the locking block 3 to move, eliminating the need for manual adjustment. Regardless of the installation orientation, before closing the door, the trigger tongue assembly 8 extends out of the lock housing 7, at which point the locking block 3 disengages the first or second chute 13, 14. The bolt, reacting to the reaction force of the door frame, automatically rotates and switches. When the trigger tongue assembly 8 retracts into the lock housing 7, the locking block reset spring 4 engages the corresponding chute, locking the latch bolt 1 (preventing it from rotating).

[0076] In actual use: the trigger tongue assembly 8 may include a trigger tongue 81 and a tongue frame 82. In actual use, the trigger tongue 81 may be rotatably mounted on the tongue frame 82 as needed.

[0077] like Figure 2 、 3 As shown in Figures 4 and 5 , in this embodiment, the locking block 3 is rotatably mounted on the lock housing 7. The locking block 3 has a first limiting strip 31 and a pressure-bearing portion 32. The first limiting strip 31 is used to cooperate with the first sliding groove 13 or the second sliding groove 14.

[0078] The unlocking portion 821 cooperates with the pressed portion 32 . When the trigger tongue assembly 8 extends out of the lock housing 7 , the unlocking portion 821 drives the locking block 3 to rotate through the pressed portion 32 .

[0079] The cooperation between the pressure-bearing portion 32 and the unlocking portion 821 also plays a role in noise reduction to a certain extent, preventing the trigger tongue assembly 8 from directly hitting the lock housing 7 at a high speed.

[0080] like Figure 2 As shown, in this embodiment, the lock housing 7 has a limit seat 71, the inclined tongue plate 2 has a limit portion 21 that cooperates with the limit seat 71 and limits the maximum distance that the inclined tongue plate 2 can move outward, and a buffer pad 10 is provided between the limit seat 71 and the limit portion 21.

[0081] The design of the cushioning pad 10 plays a role in reducing noise.

[0082] like Figure 5 、 6 As shown in Figures 7 and 7 , in this embodiment, the first rotation axis 100 is parallel to the first working surface 11 and the second working surface 12 ;

[0083] A symmetry plane 15 is defined between the first working surface 11 and the second working surface 12 . The first working surface 11 and the second working surface 12 are symmetrically arranged with respect to the symmetry plane 15 . The first rotation axis 100 is located on the symmetry plane 15 .

[0084] The first sliding groove 13 and the second sliding groove 14 are symmetrical with respect to the symmetry plane 15 .

[0085] like Figure 5 、 6 As shown in Figures 7 and 7 , in this embodiment, the first chute 13 is arranged parallel to the first working surface 11 , and the second chute 14 is arranged parallel to the second working surface 12 ;

[0086] The length direction of the first sliding groove 13 is perpendicular to the first rotation axis 100 , and the length direction of the second sliding groove 14 is perpendicular to the first rotation axis 100 .

[0087] In actual use, the locking block reset elastic member 4, the inclined tongue plate reset elastic member 5, and the trigger tongue reset elastic member 9 can be components such as compression springs, tension springs, torsion springs, and spring pieces.

[0088] Example 2

[0089] The difference between this embodiment and embodiment 1 is that the locking block reset elastic member 4 is not provided in this embodiment, the trigger tongue assembly 8 is linked with the locking block 3 (the unlocking portion 821 is linked with the locking block 3), and the locking block 3 is completely driven to move by the trigger tongue assembly 8. In actual use, the trigger tongue assembly 8 and the locking block 3 can be realized by the cooperation of the driving groove and the driving protrusion.

[0090] Specifically: when the trigger tongue assembly 8 extends out of the lock housing 7, the unlocking portion 821 applies a force to the locking block 3, causing the locking block 3 to move and disengage from the first sliding groove 13 or the second sliding groove 14. At this time, the locking block 3 can rotate relative to the inclined tongue plate 2; when the trigger tongue assembly 8 retracts into the lock housing 7, the unlocking portion 821 drives the locking block 3 to move, causing the locking block 3 to move toward the corresponding sliding groove.

[0091] Example 3
