Fig. 1 is a schematic view of a door lock structure 100 according to a first embodiment of the present invention; FIG. 2 is an exploded view of the door lock structure 100 shown in FIG. 1; fig. 3 is a partial schematic view of a door lock structure 100 according to a second embodiment. As shown in fig. 1 and 3, a door lock structure 100 according to an embodiment of the present invention includes a fixing panel 140, a transmission member 110, a latch bolt assembly, and a position limiting member 130; the fixing panel 140 is configured with a latch hole 141; the bolt assembly comprises a bolt 121 and a connecting rod 122 connected to the bolt 121, and the connecting rod 122 is slidably connected with one end of the transmission piece 110; the transmission part 110 is used for being connected with a handle; when the transmission member 110 rotates around its axis, it drives the connecting rod 122 to move along its length direction, so that the latch bolt 121 extends and retracts relative to the fixing panel 140; the limiting member 130 is connected to one end of the connecting rod 122 close to the latch bolt 121, and when the latch bolt 121 extends out of the latch bolt hole 141 relative to the fixing panel 140, the limiting member 130 abuts against the fixing panel 140.

Specifically, as shown in fig. 3, when no external force is applied to the handle or the latch bolt 121, the latch bolt 121 is exposed to the outside with respect to the fixing panel 140. When the door is closed without operating the lever handle, an external force is directly applied to the latch tongue 121 to retract the latch tongue 121. There are two situations for the external force acting on the latch bolt 121 at this time: the first is that the direction of the external force is parallel to the length direction of the connecting rod 122, and the second is that the direction of the external force forms an included angle with the length direction of the connecting rod 122.

When the direction of the external force is parallel to the length direction of the connecting rod 122, the latch bolt 121 may be directly retracted with respect to the fixing panel 140 because the direction of the external force is identical to the telescopic direction of the latch bolt 121.

Taking fig. 3 as an example, when the external force direction forms an angle with the length direction of the connecting rod 122, the external force can be decomposed into a decomposition force F1 along the Z direction, i.e. the length direction of the connecting rod 122, and a decomposition force F2 along the X direction, i.e. the direction perpendicular to the length direction of the connecting rod 122. When the Z-direction resolving force F1 acts on the latch bolt 121 to retract the latch bolt 121, and the X-direction resolving force F2 acts on the latch bolt 121, the latch bolt 121 tends to deflect downward relative to the fixed panel 140, and when the fixed panel 140 is regarded as a fulcrum, the corresponding connecting rod 122 and the stopper 130 tend to deflect upward relative to the fixed panel 140. Since the connecting rod 122 is connected to the transmission member 110, the transmission member 110 limits the upward deflection of the connecting rod 122 relative to the fixed panel 140, that is, the connecting rod 122 receives a part of downward acting force applied by the transmission member 110, and when the acting force forms an angle with the downward acting force, the connecting rod 122 receives a downward resolving force of the acting force along the X direction; meanwhile, since the limiting member 130 abuts against the fixing panel 140, the limiting member 130 cannot deflect upward relative to the fixing panel 140, that is, the limiting member 130 is also subjected to a downward acting force or a resolving force applied by the fixing panel 140, and the entire latch bolt assembly is in a horizontal state and cannot deflect. That is to say, the external force that acts on spring bolt 121 is balanced jointly by locating part 130 and connecting rod 122, because locating part 130 has undertaken partial external force to reduced the effort that driving medium 110 that connecting rod 122 received exerted, and then reduced connecting rod 122 because the risk that the effort takes place to warp, guarantee that the spring bolt subassembly can normally stretch out and draw back, prolonged spring bolt subassembly's life. In addition, when the lock tongue 121 extends out relative to the fixing panel 140, the limiting member 130 abuts against the fixing panel 140, so that when the lock tongue 121 is installed, the installation position of the lock tongue 121 is limited by the limiting member 130, the risk that the lock tongue 121 is inclined relative to the lock tongue hole 141 or the lock tongue 121 is reversely installed is reduced, the exposed size of the lock tongue 121 is consistent with the target size, the attractiveness of the lock tongue is improved, and the use experience of a user is improved.

As shown in fig. 3, in an embodiment, the limiting member 130 includes a first limiting plate 131 and a reinforcing plate 132, the first limiting plate 131 is connected between the bolt 121 and the connecting rod 122, and the reinforcing plate 132 is connected to the first limiting plate 131 and the connecting rod 122. Through setting up reinforcing plate 132, further promote the joint strength between first limiting plate 131 and the connecting rod 122, guarantee the intensity and the life of first limiting plate 131.

As shown in fig. 2, in one embodiment, the dimension of the first position limiting plate 131 in the Y direction, that is, the width of the first position limiting plate 131 is greater than the width of the latch hole 141 in the width direction of the fixing panel 140, so that when the connecting rod moves in the Z direction, since the width of the first position limiting plate 131 is greater than the width of the latch hole 141, the first position limiting plate 131 does not extend out of the latch hole, so that the first position limiting plate 131 can abut against the sidewall of the fixing panel 140. It is understood that the size of the first stopper plate 131 in the X direction, that is, the length of the first stopper plate 131, may be greater than the size of the latch hole 141 in the length direction of the fixing panel 140. In other embodiments, the first limiting plate may be located on one side of the connecting rod along the Y direction or the X direction, that is, the length or the width of the first limiting plate is greater than one half of the size of the latch hole, so that the first limiting plate can abut against the fixing panel.

As shown in fig. 2, in one embodiment, the transmission member 110 is configured with a first sliding groove 111 along its length. For example, the initial position of the transmission member 110 is the position shown in fig. 2, when the handle drives the transmission member 110 to rotate clockwise, the first sliding slot 111 generates a leftward displacement in the X direction and a downward displacement in the Z direction, and the position of the connecting rod 122 in the X direction is fixed relative to the fixed panel 140, so that the leftward movement of the transmission member 110 relative to the connecting rod 122 is represented by the fact that the connecting rod 122 moves rightward in the X direction relative to the first sliding slot 111 to accommodate the leftward displacement of the transmission member 110 in the X direction, and the locking tongue 121 retracts relative to the fixed panel 140 by the downward displacement of the transmission member 110 in the Z direction caused by the descending of the connecting rod 122 in the Z direction.

As shown in fig. 2 and 4, in a specific embodiment, the connecting rod 122 includes a head 1221 and a rod 1222, the radial dimension of the head 1221 is greater than the radial dimension of the rod 1222, the rod 1222 extends into the first sliding slot 111, and the head 1221 abuts against a side of the transmission member 110 facing away from the latch bolt 121, i.e., an underside of the transmission member. Thus, when the transmission member 110 rotates clockwise and downward, the head 1221 of the connecting rod 122 abuts against the bottom of the transmission member 110, and the transmission member 110 is provided with the first sliding slot 111 extending along the X direction, so that the transmission member 110 drives the connecting rod 122 to move downward. In other embodiments, it is also possible that the sliding groove is recessed with a clamping groove along two groove walls in the Y direction, the head portion is clamped in the clamping groove, and the connecting rod can move along the clamping groove along the X direction, so that the transmission member drives the connecting rod to lift.

As shown in fig. 2, in one embodiment, the door lock structure 100 further includes a housing 150 connected to the fixing panel 140, the transmission member 110 is rotatably connected to the housing 150, the housing 150 is configured with a first limiting portion 151, the first limiting portion 151 is in a T-shaped structure, and a second sliding groove 1511 is configured along a length direction of the connecting rod 122, and the connecting rod 122 is slidably connected to a groove wall of the second sliding groove 1511. When the transmission member 110 rotates clockwise or counterclockwise, under the limiting effect of the second sliding groove 1511, the connecting rod 122 cannot rotate therewith, and can only move up and down along the second sliding groove 1511, so as to guide the extension and retraction of the latch bolt 121, so that the movement of the latch bolt is more stable, the reliability of the extension and retraction of the latch bolt 121 is ensured, and the stability of the door opening and closing operations is further ensured.

As shown in fig. 2 and 4, in one embodiment, the door lock structure 100 further includes an elastic member 160, the elastic member 160 is sleeved on the connecting rod 122, one end of the elastic member 160 abuts against the limiting member 130, and the other end of the elastic member 160 abuts against the first limiting portion 151. As such, when an external force is applied to the transmission member 110 to retract the latch bolt 121 with respect to the fixing panel 140, i.e., the connection rod 122 moves downward, the elastic member 160 is compressed. After the external force acting on the handle and the transmission member 110 disappears, the elastic member applies a restoring force moving upward to the latch bolt, and the latch bolt 121 can be automatically restored to the extended state under the action of the elastic member 160. In other embodiments, an external force may also be applied to the handle to rotate the transmission member 110 counterclockwise to drive the connecting rod 122 to move upward, so that the latch tongue 121 extends relative to the fixing panel 140.

As shown in fig. 2 and 4, in one embodiment, the housing 150 is configured with a second limiting portion 152, and one end of the transmission member 110 away from the lock tongue 121 is configured with a third limiting portion 112, when the transmission member 110 rotates counterclockwise until the lock tongue extends out, the third limiting portion 112 just abuts against the second limiting portion 152, and the rotation stroke of the transmission member 110 is limited by the cooperation of the second limiting portion 152 and the third limiting portion 112, so that the rotation of the transmission member 110 is more stable and controllable.

By providing the cover 170, the various components are enclosed within the housing 150, which improves the integrity of the door lock structure 100 for storage and transportation.

As shown in fig. 4, in an embodiment, the door lock structure 100 further includes a back lock knob 190 and a second stopper plate 180. Wherein, the housing 150 is provided with a plurality of limiting posts 153, and the second limiting plate 180 is provided with a corresponding number of waist-shaped holes, which are correspondingly connected to the plurality of limiting posts 153. Specifically, the reverse lock knob 190 is provided with a third sliding groove extending along the Z direction, and the second limiting plate 180 is slidably connected to the third sliding groove, and the connection relationship is similar to the connection manner between the connecting rod and the second sliding groove in fig. 2, except that the third sliding groove extends along the Z direction, and the second sliding groove extends along the X direction. When the reverse locking knob 190 is rotated clockwise, the reverse locking knob 190 generates downward displacement and rightward displacement, and the third sliding chute extending along the Z direction is arranged to adapt to the downward displacement generated by the reverse locking knob 190 relative to the second limiting plate 180, so that the reverse locking knob 190 pushes the second limiting plate 180 to move rightward until the fourth limiting portion 113 at the left end of the transmission member 110 abuts against the bottom end of the second limiting plate 180. At this moment, under second limiting plate 180's limiting displacement, the unable clockwise rotation of driving medium 110, consequently the unable relatively fixed panel withdrawal of spring bolt 121 rotates the unable operation that opens the door of realizing of handle, prevents that child from opening the unsafe event that leads to by mistake and taking place, if need open the door, need earlier with the anti-lock knob 190 anticlockwise rotation reset make second limiting plate 180 remove left, not influenced until the clockwise rotation of the spacing portion 113 of fourth.
