The buffer ring 14 and the buffer ring 15 are each made of an elastic material such as rubber or silicone.

Referring to Figures 4, 5 and 6, the housing 11 also has a supporting frame 112 disposed on the base plate 110 and corresponding to the position of the buffer collar 14. The supporting frame 112 is formed with a receiving space 113 connected to the oblique tongue hole 141, two through holes 114 connected to the bottom of the receiving space 113 and spaced along the second horizontal direction D2, and a through hole 115 connected to an end of the receiving space 113 opposite to the oblique tongue hole 141. Each of the through holes 114 is elongated and its length extends along the first horizontal direction D1. The housing 11 also has a shaft 116 disposed on the base plate 110 and located obliquely below the supporting frame 112, and a stud 117 disposed on the base plate 110 and located below the supporting frame 112.

Referring to Figures 2, 4, 6 and 7, the latch bolt 2 is rotatably and telescopically disposed in the latch bolt hole 141 and the receiving space 113. The latch bolt 2 can be pushed and rotated and moved from a protruding position partially protruding from the latch bolt hole 141 (as shown in Figure 4) to a retracted position retracted into the latch bolt hole 141 (as shown in Figure 13). The latch bolt 2 is a diamond-shaped latch bolt. The latch bolt 2 is detachably assembled to the housing 1. The latch bolt 2 can be disposed in the latch bolt hole 141 in a forward direction, or in a reverse direction after being rotated 180 degrees. In this way, the door lock device 100 can be applied to the occasion of an inner-opening door or an outer-opening door.

Referring to FIGS. 4, 6, 7 and 8, the oblique tongue 2 includes a tongue block 21, a buffer pad 22, and a latch 23. The tongue block 21 has a rhombus body 211 and a plurality of protrusions 212. The rhombus body 211 has an inner block 213 in the shape of a triangular block, and an outer block 214 in the shape of a triangular block connected to the outer side of the inner block 213. The inner block 213 is accommodated in the receiving space 113 and has two surfaces 215 spaced apart and opposite to each other along the longitudinal direction D3. The number of the protrusions 212 is six, for example, and every three of the protrusions 212 are protruding from the corresponding surface 215 and define two slots 216 together with the corresponding surface 215. The slots 216 are spaced apart along the second horizontal direction D2. Each of the slots 216 is in the shape of a long slot and its length extends along the first horizontal direction D1. The outer block 214 is penetrated in the oblique tongue hole 141 and partially protrudes out of the oblique tongue hole 141. The outer block 214 is recessed to form a groove 217, and a plug hole 218 connected to the groove 217 and extending along the longitudinal direction D3.

The buffer pad 22 is made of an elastic material such as rubber or silicone. The buffer pad 22 is embedded in the groove 217 and partially protrudes from the outer block 214 to contact a door frame (not shown). The buffer pad 22 is formed with a through hole 221 extending along the longitudinal direction D3 and connected to the insertion hole 218. The latch 23 is inserted through the insertion hole 218 of the tongue block 21 and the through hole 221 of the buffer pad 22 and interferes with the outer block 214 and the buffer pad 22, thereby firmly fixing the tongue block 21 and the buffer pad 22 together.

Referring to Figures 4, 5, 6, 7 and 8, the blocking assembly 3 is disposed in the accommodation space 10 of the housing 1 and includes a blocking member 31 and a biasing spring 32. The blocking member 31 is pivoted to the shaft 116 of the housing 1. The blocking member 31 can be operated to rotate between a blocking position (as shown in Figure 4) that blocks the latch bolt 2 to limit the rotation of the latch bolt 2 in the protruding position, and a release position (as shown in Figure 12) that is separated from the latch bolt 2. The biasing spring 32 is used to apply a spring force to the blocking member 31 toward the blocking position so that the blocking member 31 remains in the blocking position.

The stopper 31 is an integrated single component manufactured by punching and bending. The stopper 31 has a stopper rod 311 for stopping the oblique tongue 2, and a push rod 312 extending from the stopper rod 311. The stopper rod 311 is rotatably pivoted to the shaft rod 116. The cross section of the stopper rod 311 taken along the longitudinal direction D3 is in a U-shape with an opening facing upward. The stopper rod 311 has two stopper ridges 313 spaced apart along the second horizontal direction D2. Each of the stopper ridges 313 is in a long strip shape and its length extends along the first horizontal direction D1. Each of the blocking ridges 313 is used to pass through the corresponding through hole 114 of the supporting frame 112 and to be engaged with the corresponding slot 216 of the oblique tongue 2. The push rod 312 has a horizontal rod body 314 extending horizontally from the blocking rod 311, and a vertical rod body 315 extending downward from the bottom end of the horizontal rod body 314.

When the blocking member 31 is at the blocking position, the blocking ridges 313 are respectively engaged with the corresponding slots 216 of the latch tongue 2, thereby limiting the rotation of the latch tongue 2 when it is at the protruding position. When the blocking member 31 is at the releasing position, the blocking ridges 313 are respectively separated from the corresponding slots 216 of the latch tongue 2, so that the latch tongue 2 can rotate when it is at the protruding position. By forming the slots 216 on opposite sides of the oblique tongue 2, when the oblique tongue 2 is inserted into the oblique tongue hole 141 in the forward direction, the stopper 31 blocks the corresponding slots 216 on one side of the oblique tongue 2, and when the oblique tongue 2 is inserted into the oblique tongue hole 141 in the reverse direction, the stopper 31 blocks the corresponding slots 216 on the other side of the oblique tongue 2. In this way, whether the oblique tongue 2 is inserted into the oblique tongue hole 141 in the forward direction or the reverse direction, the stopper 31 can block the oblique tongue 2.

The bias spring 32 is a torsion spring sleeved on the stud 117. The two ends of the bias spring 32 abut against the shell 11 of the outer shell 1 and the bottom end of the stop rod 311 of the stop member 31 respectively.

Referring to FIGS. 4, 5, 6, 7 and 9, the deceleration mechanism 4 is disposed in the accommodation space 10 of the housing 1 and includes a gear 41, a sleeve 42, a gear 43, a gear shaft 44, a bearing 45, a first compression spring 46, and a second compression spring 47. The gear 41 has a gear segment 411, an abutting segment 412, and two sliders 413. The gear segment 411 extends along the first horizontal direction D1 and penetrates the through hole 115 of the supporting frame 112. The abutting segment 412 is connected to the right end of the gear segment 411 and extends along the second horizontal direction D2. The abutment section 412 extends into the receiving space 113 of the support frame 112 and abuts against the inner block 213 of the oblique tongue 2. The slide blocks 413 are convexly disposed on the rear side of the tooth section 411 and are respectively slidably connected to the guide grooves 111 of the housing 1 (as shown in FIG. 3 ). By the slide blocks 413 being slidably connected to the guide grooves 111, the tooth 41 is restricted to slide only along the first horizontal direction D1. By the abutment section 412 abutting against the inner block 213 of the oblique tongue 2, the tooth 41 can be driven and moved by the oblique tongue 2.

The sleeve 42 is disposed on the base plate 110 of the housing 11 and is located on the left side of the support frame 112. The sleeve 42 forms a barrel groove 421 and two positioning grooves 422 connected to the opposite sides of the barrel groove 421 and spaced apart along the first horizontal direction D1. The sleeve 42 has a stop shoulder surface 423 adjacent to the rear end of the barrel groove 421. The gear 43 and the gear shaft 44 are accommodated in the barrel groove 421. The gear 43 is sleeved on the gear shaft 44 and engaged with the gear segment 411 of the gear 41. The bearing 45 has a body 451 that is accommodated in the barrel groove 421 and supports the gear shaft 44, and two positioning blocks 452 that are respectively protruded on opposite sides of the body 451. The positioning blocks 452 are respectively engaged in the positioning grooves 422. In this way, the bearing 45 can be prevented from rotating relative to the sleeve 42.

The first compression spring 46 is disposed in the receiving space 113 of the supporting frame 112. The two ends of the first compression spring 46 abut against the abutment section 412 of the tooth bar 41 and the supporting frame 112 respectively. The first compression spring 46 applies elastic force to the inclined tongue 2 toward the protruding position through the abutment section 412 of the tooth bar 41. Thereby, the inclined tongue 2 can be kept in the protruding position.

The second compression spring 47 is accommodated in the barrel groove 421 of the sleeve 42. Two ends of the second compression spring 47 abut against the body 451 of the bearing 45 and the cover plate 12 respectively. The second compression spring 47 applies elastic force to the bearing 45 in the direction of the stop shoulder surface 423, so that the body 451 of the bearing 45 abuts against the stop shoulder surface 423 and the gear 43 is engaged with the gear segment 411 of the gear 41. In this way, the gear 43 can be kept in a position where it is engaged with the gear segment 411, so as to prevent the bearing 45 and the gear 43 from shaking in the barrel groove 421 of the sleeve 42, thereby causing the gear 43 to separate from the gear segment 411.

Referring to Fig. 4, Fig. 5 and Fig. 10, the housing 11 further has a guide post 118 disposed on the base plate 110 and located below the push rod 312 of the stopper 31. The bolt assembly 5 is disposed in the accommodating space 10 of the housing 1 and includes a sliding plate 51 and a plurality of bolts 52. The sliding plate 51 is formed with a long slide groove 511. The long slide groove 511 extends along the first horizontal direction D1 and is slidably connected to the guide post 118. The bolts 52 are disposed at the right end of the sliding plate 51 and are arranged at intervals along the longitudinal direction D3. Each of the bolts 52 is penetrated in the corresponding bolt hole 132 and can protrude from the corresponding bolt hole 132. The bolt assembly 5 can be operated to move between a locked position (as shown in FIG. 4 ) and an unlocked position (as shown in FIG. 12 ). When the bolt assembly 5 is in the locked position, each bolt 52 partially protrudes out of the corresponding bolt hole 132. When the bolt assembly 5 is in the unlocked position, each bolt 52 retracts into the corresponding bolt hole 132.

The first push protrusion 622 is between the cross bar 314 of the push rod 312 and the second push protrusion 623. The first push protrusion 622 is used to push the cross bar 314 of the push rod 312 to rotate the blocking member 31 from the blocking position to the release position.

The cam member 63 has a pivot ring 631 pivotally connected to the pivot shaft 119, and a push arm 632 protruding from the outer peripheral surface of the pivot ring 631. The push arm 632 is located between the first push protrusion 622 and the second push protrusion 623 of the transmission gear 62 and is accommodated in the accommodation groove 512 of the sliding plate 51. The push arm 632 is used to push the first side edge 513 of the sliding plate 51 to move the bolt assembly 5 toward the upper locking position. The push arm 632 is also used to push the second side edge 514 of the sliding plate 51 to move the bolt assembly 5 toward the unlocking position. The cam member 63 can be driven by the transmission gear 62 to swing between a first swing position (as shown in FIG. 4 ) and a second swing position (as shown in FIG. 12 ). When the cam member 63 is in the first swing position, the bolt assembly 5 is in the upper locking position, and when the cam member 63 is in the second swing position, the bolt assembly 5 is in the unlocking position.

The first pushing protrusion 622 of the transmission gear 62 is used to push the pushing arm 632 so that the cam member 63 is swung from the second swing position to the first swing position. The second pushing protrusion 623 of the transmission gear 62 is used to push the pushing arm 632 so that the cam member 63 is swung from the first swing position to the second swing position.

The key driving mechanism 7 is disposed on the housing 1 and includes a rotating member 71 and a transmission plate 72. The rotating member 71 is rotatably pivoted to the base plate 110 of the housing 11 and the cover plate 12. The rotating member 71 has a rotating ring 711 and a push arm 712 protruding from the outer peripheral surface of the rotating ring 711. The rotating ring 711 is formed with a key hole 713. The key hole 713 is used for inserting a key (not shown) so that the key can drive the rotating member 71 to rotate.

The driving plate 72 is pivoted to the pivot post 120 of the housing 1 and can be driven by the rotating member 71 to rotate. The driving plate 72 has a plate body 721 pivoted to the pivot post 120, and a push-up protrusion 722 protruding from one side of the plate body 721 and adjacent to the top of the plate body 721. The plate body 721 has a push-up tip 723 located on the left side of the push-up protrusion 722. The plate body 721 is formed with an arc-shaped slide groove 724 for the guide post 118 to pass through and can slide relative to the guide post 118. The pushing protrusion 722 is used to push the vertical rod body 315 of the pushed rod 312 to rotate the blocking member 31 from the blocking position to the release position. The pushing tip 723 is used to push the pushing arm 632 of the cam member 63 to swing the cam member 63 from the first swing position to the second swing position.

The transmission plate 72 can be driven by the rotating member 71 to rotate between an initial position (as shown in FIG. 4 ) and a push position (as shown in FIG. 15 ). When the transmission plate 72 is in the initial position, the push tip 723 and the push protrusion 722 are separated from the push arm 632 and the vertical rod body 315 respectively. When the transmission plate 72 is in the push position, the push tip 723 pushes against the push arm 632 to limit the cam member 63 in the second swing position, and the push protrusion 722 pushes against the vertical rod body 315 to limit the blocking member 31 in the release position.

Referring to Figs. 2, 4 and 5, the tongue mechanism 8 is disposed in the accommodation space 10 of the housing 1 and partially protrudes from the housing 1. The tongue mechanism 8 includes a guide plate 81, a sliding rod 82, a tongue 83, a compression spring 84, and a sensing unit 85. The guide plate 81 is disposed on the base plate 110 of the housing 11. The sliding rod 82 is slidably connected to the guide plate 81. The tongue 83 is rotatably pivoted to the sliding rod 82. The tongue 83 is inserted into the tongue hole 151 and partially protrudes from the tongue hole 151. The compression spring 84 is sleeved on the sliding rod 82 and abuts between the sliding rod 82 and the guide plate 81. The sensing unit 85 has a circuit board 851 and a switch 852 disposed on the circuit board 851. The circuit board 851 is electrically connected to the circuit assembly 611 of the driving assembly 61 by wired or wireless means. The switch 852 is used for contacting the sliding rod 82. The contact tongue 83 can be operated to move between an extended position (as shown in FIG. 4 ) partially protruding from the housing 1 and a retracted position (as shown in FIG. 14 ) not protruding from the housing 1. When the contact tongue 83 is in the extended position, the sliding rod 82 contacts the switch 852. When the contact tongue 83 is in the retracted position, the sliding rod 82 is separated from the switch 852, and the switch 852 generates a signal and transmits it to the circuit assembly 611 of the drive assembly 61 through the circuit board 851 to control the drive assembly 61 to drive the transmission gear 62 to rotate, so that the transmission gear 62 drives the cam member 63 to swing and further push the bolt assembly 5 to the upper locking position.

Referring to FIG. 11 , the contact tongue 83 includes a tongue block 831, a buffer pad 832, and a latch 833. The tongue block 831 is triangular and pivotally connected to the sliding rod 82. The tongue block 831 is recessed to form a groove 834 and an insertion hole 835 connected to the groove 834. The buffer pad 832 is made of an elastic material such as rubber or silicone. The buffer pad 832 is embedded in the groove 834 and partially protrudes from the tongue block 831 to contact the door frame (not shown). The buffer pad 832 is formed with a through hole 836 extending along the longitudinal direction D3 and connected to the insertion hole 835. The latch 833 is inserted through the insertion hole 835 of the tongue block 831 and the through hole 836 of the buffer pad 832 and interferes with the tongue block 831 and the buffer pad 832, thereby firmly fixing the tongue block 831 and the buffer pad 832 together.

Referring to FIG. 12 , when the door panel is opened, the first push protrusion 622 of the transmission gear 62 of the electronic drive mechanism 6 pushes against the bottom end of the crossbar body 314 of the stopper 31 to limit the stopper 31 in the release position. At this time, the stopper rod 311 of the stopper 31 compresses the bias spring 32, so that the bias spring 32 is bent and deformed and accumulates a restoring elastic force. The second push protrusion 623 of the transmission gear 62 pushes against the right end of the push arm 632 of the cam member 63 to limit the cam member 63 in the second swing position. At this time, the push arm 632 presses against the second side 514 of the sliding plate 51 to limit the latch assembly 5 in the unlocking position. In addition, the latch 2 remains in the protruding position, and the contact tongue 83 remains in the extended position.

Referring to Fig. 9, Fig. 12, Fig. 13 and Fig. 14, during the process of rotating the door panel toward the door frame to close the door, the buffer pad 22 of the latch bolt 2 will contact the door frame, and the latch bolt 2 will be pushed by the door frame to rotate and move inward to the retracted position. During the rotation and movement of the latch bolt 2, the gear 41 will be driven to slide inward, and the gear 41 will drive the gear 43 to rotate through the gear segment 411, and the gear 41 will compress the first compression spring 46 through the abutment segment 412 to deform it and store the restoring elastic force. By controlling the friction between the gear 43 and the gear segment 411 of the gear 41 and the friction between the gear shaft 44 and the bearing 45, and the two ends of the first compression spring 46 abutting against the abutting segment 412 of the gear 41 and the supporting frame 112 respectively, the inclined tongue 2 can play a role of buffering and decelerating the gear 41 when driving the gear 41 to slide inward, thereby reducing the noise generated by the inclined tongue 2 and the gear 41 during the retraction movement process.

At the same time, the contact tongue 83 contacts the door frame, and the contact tongue 83 is pushed by the door frame to rotate and move inward to the retracted position. The contact tongue 83 will drive the sliding rod 82 to slide inward during the rotation and movement process. When the sliding rod 82 slides, it will compress the compression spring 84 to deform it and store the return force, and the sliding rod 82 will separate from the switch 852. At this time, the switch 852 generates the signal and transmits it to the circuit assembly 611 of the drive component 61 through the circuit board 851.

Referring to Fig. 4, Fig. 5 and Fig. 8, when the door panel is in the closed state, the first compression spring 46 rebounds the tooth bar 41 and the latch bolt 2 by the accumulated restoring elastic force, so that the latch bolt 2 rotates and moves outward and automatically returns to the protruding position. At this time, the latch bolt 2 is locked in the door frame. In addition, the circuit assembly 611 controls the operation of the motor 612 and drives the driving gear 62 to rotate along a first rotation direction R1 through the gear set 613. During the rotation of the driving gear 62, the first pushing protrusion 622 will first move away from the crossbar body 314 of the stopper 31. The stopper 31 is rebounded by the restoring force accumulated by the bias spring 32, so that the stopper 31 can automatically rotate around the shaft 116 along the first rotation direction R1 and return to the stop position. The stopper ribs 313 of the stopper 31 are respectively engaged with the corresponding slots 216 of the latch 2, thereby limiting the rotation of the latch 2 when it is in the protruding position.

Subsequently, the first pushing protrusion 622 of the driving gear 62 pushes the pushing arm 632 of the cam member 63 to drive the cam member 63 to rotate from the second swing position along the first rotation direction R1. During the rotation process, the cam member 63 pushes the first side edge 513 of the sliding plate 51 through the pushing arm 632 to cause the bolt assembly 5 to move toward the upper locking position along the first horizontal direction D1. When the driving gear 62 drives the cam member 63 to swing to the first swing position, the driving gear 62 stops rotating, so that the cam member 63 is positioned at the first swing position, and the bolt assembly 5 is positioned at the upper locking position where the bolt 52 is locked in the door frame. Thereby, the door panel can be locked to the door frame through the door locking device 100 (as shown in FIG. 1 ).

Referring to FIG. 5 and FIG. 12 , the door lock device 100 is unlocked by the electronic drive mechanism 6 as follows: when the circuit assembly 611 of the drive component 61 of the electronic drive mechanism 6 receives an unlocking signal, the circuit assembly 611 controls the motor 612 to operate and drives the transmission gear 62 to rotate in a second rotation direction R2 opposite to the first rotation direction R1 through the gear set 613. During the rotation of the transmission gear 62, the first pushing protrusion 622 pushes the crossbar 314 of the blocking member 31 to rotate the blocking member 31 around the shaft 116 along the second rotation direction R2, and the second pushing protrusion 623 pushes the pushing arm 632 of the cam member 63 to drive the cam member 63 to rotate from the first swing position along the second rotation direction R2. During the rotation, the cam member 63 pushes the second side edge 514 of the sliding plate 51 through the pushing arm 632 to cause the bolt assembly 5 to move along the first horizontal direction D1 toward the unlocking position. When the driving gear 62 drives the cam member 63 to swing to the second swing position, the driving gear 62 stops rotating, so that the blocking member 31 is positioned at the release position, the cam member 63 is positioned at the second swing position, and the bolt assembly 5 is positioned at the unlocking position where the bolt 52 moves away from the door frame.

Referring to FIG. 1 and FIG. 15 , the operation of unlocking the door lock device 100 by the key driving mechanism 7 is described as follows: first, the key is inserted into the key hole 713 of the rotating member 71, and the rotating member 71 is driven by the key to rotate along the first rotation direction R1. During the rotation process, the rotating member 71 pushes the transmission plate 72 through the pushing arm 712 to rotate around the hinge column 120 along the first rotation direction R1. During the rotation of the transmission plate 72, the push projection 722 pushes the vertical rod 315 of the stopper 31 to rotate the stopper 31 around the shaft 116 along the second rotation direction R2, and the push tip 723 pushes the push arm 632 of the cam member 63 to drive the cam member 63 to rotate from the first swing position along the second rotation direction R2. During the rotation, the cam member 63 pushes the second side 514 of the sliding plate 51 through the push arm 632 to cause the bolt assembly 5 to move along the first horizontal direction D1 toward the unlocking position. When the transmission plate 72 rotates to the top position, the blocking member 31 is positioned at the release position, the cam member 63 is positioned at the second swing position, and the bolt assembly 5 is positioned at the unlocking position where the bolt 52 moves away from the door frame.

Referring to Figures 12, 13 and 15, the door lock device 100 is in the unlocked state, and the user can push the door panel open. The buffer pad 22 of the latch bolt 2 contacts the door frame and is pushed by the door frame, so that the latch bolt 2 rotates and moves inward to the retracted position. When the door panel is opened, the first compression spring 46 rebounds the latch bolt 2, so that the latch bolt 2 automatically returns to the protruding position. The compression spring 84 rebounds the sliding rod 82 and the contact tongue 83, so that the contact tongue 83 returns to the extended position and the sliding rod 82 contacts the switch 852.

Referring to Fig. 1, Fig. 4 and Fig. 6, when the door panel is opening or closing, the latch bolt 2 and the contact bolt 83 contact the door frame through the buffer pad 22 and the buffer pad 832 respectively, which can prevent the tongue block 21 and the tongue block 831 from directly colliding with the door frame to generate noise, thereby achieving a noise-reducing effect. In addition, the bump block 212 of the latch bolt 2 is blocked by the buffer ring 14, which can prevent the latch bolt 2 from escaping from the latch bolt hole 141 so that the latch bolt 2 is positioned at the protruding position, and the effects of buffering, deceleration and noise reduction can be achieved. Furthermore, by blocking the tongue block 831 of the contact tongue 83 by the buffer ring 15, the contact tongue 83 can be prevented from escaping from the contact tongue hole 151 so that the contact tongue 83 is positioned in the extended position, and the effects of buffering, deceleration and silencing can be achieved.

Referring to Figs. 2, 3, 16 and 17, the base plate 110 of the housing 11 is formed with a first axial hole 110a located below the support frame 112. The cover plate 12 is formed with a second axial hole 121 corresponding to the position of the first axial hole 110a. The buffer ring 14 has a ring body 142 defining the oblique tongue hole 141, and a pivot 143 connected to the bottom end of the ring body 142. The ring body 142 is mounted on the upper opening 131 of the side plate 13 to block the protrusions 212. The pivot 143 is rotatably pivoted to the first axial hole 110a and the second axial hole 121. When the side plate 13 is detached from the housing 11 and the cover plate 12, the buffer collar 14 can rotate between a closed position (as shown in FIG. 16) and an open position (as shown in FIG. 17). In the closed position, the oblique tongue hole 141 allows the diamond-shaped body 211 to pass through and the ring body 142 blocks the protrusions 212. In the open position, the oblique tongue hole 141 is separated from the diamond-shaped body 211, and the ring body 142 is separated from the protrusions 212 and does not block the protrusions 212.

When the latch bolt 2 needs to be reversed so that the door lock device 100 is applied to either an inwardly opening door or an outwardly opening door, the side plate 13 is first detached from the housing 11 and the cover plate 12 to separate the upper opening 131 of the side plate 13 from the ring body 142 of the buffer ring 14. Then, the latch bolt 2 is pushed inward to move inward from the protruding position to the retracted position to separate the protruding blocks 212 from the ring body 142 of the buffer ring 14. Next, the buffer ring 14 is pulled outward to rotate from the closed position to the open position, so that the oblique tongue hole 141 is separated from the rhombus body 211.

The oblique tongue 2 is pulled out of the receiving space 113, and then the oblique tongue 2 is rotated 180 degrees to turn the oblique tongue 2 upside down, and then the oblique tongue 2 is inserted into the receiving space 113. Then, the buffer ring 14 is pulled inward to rotate the buffer ring 14 from the open position to the closed position, and then the side plate 13 is assembled back to the housing 11 and the cover plate 12, and the reversing operation of the oblique tongue 2 is completed. Since the oblique tongue 2 is a diamond-shaped oblique tongue, no matter whether the oblique tongue 2 is inserted into the oblique tongue hole 141 in the forward or reverse direction, the oblique tongue 2 can rotate in the oblique tongue hole 141 and the receiving space 113. Since the latch 2 can rotate in the latch hole 141 and the receiving space 113 without being hinged with other hinge structures, the structure of the latch 2 and the housing 1 is simple, which can reduce the complexity of the structure and the manufacturing cost. In addition, the reversing operation of the latch 2 is very simple and convenient, which can improve the convenience of the reversing operation of the latch 2.

It should be noted that this implementation can also have the following different implementation forms according to needs:

One implementation mode: the number of the protrusions 212 of the oblique tongue 2 is four, and every two of the protrusions 212 are protruding from the corresponding surface 215 and define the corresponding slot 216 together with the corresponding surface 215. The number of the blocking ridge 313 of the blocking member 31 is one.

Another implementation: The number of the positioning groove 422 of the sleeve 42 and the number of the positioning block 452 of the bearing 45 are each one.

In summary, the door lock device 100 of this embodiment, through the arrangement relationship between the housing 1, the latch bolt 2 and the blocking assembly 3, has fewer components to improve assembly convenience, and can make the overall structure of the door lock device 100 simple and small in size to reduce manufacturing costs. The latch bolt 2 can be inserted into the latch bolt hole 141 in the forward direction, or inserted into the latch bolt hole 141 in the reverse direction after rotating 180 degrees. In this way, the door lock device 100 can be applied to the occasion of an inwardly opening door or an outwardly opening door. By the oblique tongue 2 and the contact tongue 83 contacting the door frame through the buffer pads 22 and 832 respectively, the tongue blocks 21 and 831 can be prevented from directly colliding with the door frame to generate noise, thereby achieving a noise-reducing effect. By the buffer ring 14 blocking the protruding blocks 212 of the oblique tongue 2, the oblique tongue 2 can be prevented from escaping from the oblique tongue hole 141, and the effects of buffering, deceleration and silencing can be achieved. By the buffer ring 15 blocking the tongue block 831 of the contact tongue 83, the contact tongue 83 can be prevented from escaping from the contact tongue hole 151, and the effects of buffering, deceleration and silencing can be achieved. The design of the deceleration mechanism 4 can reduce the noise generated by the latch 2 during the retraction process, so the purpose of this novel device can be achieved.

However, the above is only an example of the implementation of this new model, and it cannot be used to limit the scope of the implementation of this new model. All simple equivalent changes and modifications made according to the scope of the patent application of this new model and the content of the patent specification are still within the scope of this new patent.
