Description

Door lock device

Technical Field

The present application relates to a door lock device, and more particularly, to a door lock device capable of idling a handle.

Background

As shown in fig. 1A and 1B, in the conventional door lock structure 9, a key 95 drives a knob 97 to rotate a rotating shaft 92, so that the rotating shaft 92 drives an eccentric protrusion 981 of a rotating plate 98 to slide counterclockwise by an angle, and a locking plate 93 moves upward relative to a brake plate 94, so that a locking groove 931 of the locking plate 93 is embedded in a protruding locking plate 941 of the brake plate 94, when a user presses a handle 91, since the brake plate 94 on a bushing 911 of the handle 91 is limited by the locking plate 93, the handle 91 cannot drive a tongue locking block 961 of a lock body 96 to retract relative to a door frame by a linkage 910 engaged with the bushing 911, thereby achieving the purpose of locking.

However, in the conventional door lock structure, since the handle 91 cannot be pressed down during locking, when the handle 91 is hit by a foreign object instantly or a person who is not in the middle of locking maliciously rotates the handle 91, the handle 91 is easily damaged by an external force, and the catch 94 and the locking plate 93 on the bushing 911 of the handle 91 are worn away from each other, thereby making the door lock structure 9 unusable.

Therefore, how to overcome the various problems of the prior art has become an issue to be solved.

Disclosure of Invention

In view of the disadvantages of the prior art, the present application provides a door lock device, which can prevent a handle body from being damaged by being pulled by an external force when the handle body is in a locked state.

The door lock device of the present application includes: the handle structure comprises a keyhole piece, a handle assembly and an action assembly, wherein the action assembly is provided with a rotating piece for linking the handle assembly and a shaft piece matched with the rotating piece, the rotating piece is provided with a telescopic part, so that when the telescopic part is separated from the shaft piece, the rotating piece can rotate, and the shaft piece cannot rotate; and the lock structure is connected with the handle structure and is provided with a lock head which is linked with the lock hole piece and the shaft piece.

In the door lock device, the handle structure further includes a shift lever for linking the keyhole member.

In the door lock device, the handle assembly has a driving member for driving the rotating member to rotate.

In the door lock device, the acting component further has an active component for linking the keyhole component. For example, the driving member has an actuating portion configured to be displaceable relative to the rotating member to separate or approach the rotating member to extend or retract the rotating member into or out of the telescoping portion.

In the door lock device described above, the shaft member is in the form of a telescopic rod. For example, one end of the shaft member is provided with an adjusting portion arranged in a displaceable manner.

In the door lock device, the acting component further has a traction component for linking the handle component and the rotating component. For example, the pulling member has a locking portion, and the rotating member has an insertion portion for engaging with the locking portion.

In the door lock device, the acting assembly further includes an electromagnetic element and an acting member for moving the electromagnetic element, and the retractable portion moves the acting member.

In view of the above, the door lock device of the present application mainly relies on the design of the retractable portion, so that when the retractable portion separates from the shaft, the lock structure is in a locked state, and the rotating member does not drive the shaft to rotate, so that the rotating member can rotate, and the shaft does not rotate.

The invention is described in detail below with reference to the drawings and specific examples, but the invention is not limited thereto.

Fig. 2 is an exploded perspective view of a first embodiment of the door lock device 1 of the present application. As shown in fig. 2, the present application provides a door lock apparatus 1, which includes: a handle structure 1 'and a lock structure 4 connected to the handle structure 1'.

In the present embodiment, the handle structure 1' and the lock structure 4 are respectively disposed on two opposite sides of a door body 5, so that the entrance and exit direction of the doorway defined by the door body 5 is defined as the front and rear direction (as indicated by arrow X), the direction along the width of the door body 5 is defined as the left and right direction (as indicated by arrow Y), and the height direction along the door body 5 is defined as the up and down direction (as indicated by arrow Z). It should be understood that the orientations of the arrow directions X, Y, Z are used for explaining the configuration of the present embodiment, and are not particularly limited.

In addition, the door body 5 is pivoted to one side of the door frame 5a, and a door opening 50 is disposed on the other side of the door frame 5a opposite to the pivoted side.

As shown in fig. 3, 4 and 5A, the handle structure 1' includes: a housing 1a, a handle assembly 2 and an active assembly 3.

The housing 1a is groove-shaped, and has a receiving space S, and a through hole 15 communicating with the receiving space S is formed at the bottom side of the groove, and a circular convex keyhole member 11 is disposed at the bottom of the groove.

In this embodiment, the housing 1a has a plurality of positioning portions 12, such as pins, disposed in the accommodating space S for the handle structure 1' to be connected to the lock structure 4, and the accommodating space S of the housing 1a has a first positioning portion 13 and a second positioning portion 14 disposed at two opposite sides thereof, and a shift lever 16 disposed at a lower edge of the keyhole member 11 for linking the keyhole member 11, as shown in fig. 5A.

The handle assembly 2 has a handle body 21, a driving member 22 pivotally connected to the handle body 21, and a fixing plate 23 engaging with the driving member 22.

In the present embodiment, the handle body 21 is a rotating handle type and is exposed outside the housing 1 a. For example, the handle body 21 is pivotally connected to the through hole 15 of the housing 1a by the connecting section 21 a. Specifically, the connection section 21a is provided with a connection hole 211, such as a rectangular shape, on an end surface thereof.

In addition, the driving member 22 is tubular and has a rectangular through hole 221, and the driving member 22 is protruded outwardly at two opposite sides of the circumference thereof to form a wing 222.

In addition, the fixing plate 23 is provided with a rectangular shaft 231 corresponding to the through hole 221, which is inserted into the through hole 221 of the driver 22 and the connecting hole 211 of the handle body 21.

The action component 3 has a driving part 31 disposed in the receiving space S and located at the lower edge of the keyhole member 11, a rotating part 34 located below the driving part 31, a pulling part 32 linking the rotating part 34, and a shaft 33 passing through the rotating part 34.

In the present embodiment, the driving member 31 is substantially a plate, and has a shifting portion 311 standing on a surface thereof, and a first position-limiting portion 312 and a second position-limiting portion 313 formed on two opposite sides of the shifting portion 311. For example, the driving member 31 extends at a lower side thereof with an actuating portion 314, such as an elongated bar, which is configured to be displaceable relative to the rotating member 34. Specifically, the toggle portion 311 of the active element 31 engages the toggle lever 16 to interlock the keyhole element 11, and the actuating portion 314 can be separated from or close to the rotating element 34.

In addition, the rotating member 34 is substantially wheel-shaped or disc-shaped, and has a long-strip-shaped axial hole 342 formed at the wheel center, and a telescopic portion 341 is disposed at one side of the circumferential surface thereof, and a clamping opening 343 is disposed at the other side of the circumferential surface thereof. For example, an insertion part 344 is disposed at an eccentric position in the clamping opening 343, and the telescopic part 341 is connected to a rod-shaped displacement rod 345. Specifically, the actuating portion 314 shields or does not shield the retractable portion 341 to control the retractable portion 341 to extend or retract into the rotating member 34, and the retractable portion 341 extends or retracts into the rotating member 34 to lock or separate the shaft member 33.

In addition, the pulling element 32 is a plate, and has a passive portion 321 at the bottom side thereof and a locking portion 322 as a locking hole at the upper side thereof for locking the engaging portion 344 of the rotating element 34. For example, one side of the pulling member 32 is movably disposed with a cover 323 (e.g., by a spring 323a), and the cover 323 is provided with an opening 324.

In addition, the shaft 33 is in a telescopic rod form, one end of the shaft 33 penetrates through the opening 324 of the traction member 32 and the shaft hole 342 of the rotating member 34 to be connected with the rotating member 34, and the other end of the shaft 33 is provided with a drill-shaped adjusting portion 331. For example, the shaft 33 is displaceably disposed in the adjusting portion 331 so as to arbitrarily extend and contract the length of the adjusting portion 331. Specifically, a plurality of adjusting holes 332 are disposed on the circumference of the shaft 33, and the shaft is matched with a fixing portion 333 such as a screw or a bolt to be positioned on the required adjusting holes 332, so that the adjusting portion 331 of the shaft 33 can adjust the length (as shown in the adjusting direction L shown in fig. 2) according to the thickness of the door body 5, thereby facilitating the application of the shaft 33 to door bodies 5 of different specifications (thicknesses), and further improving the applicability of the handle structure 1'.

The locking structure 4 has a shaft hole 41 coupled to the shaft 33 and a locking head 40 for driving the keyhole member 11, so that the keyhole member 11 controls the locking head 40 to be fixed or loose in the door hole 50.

In this embodiment, the adjusting portion 331 of the shaft 33 is coupled to the shaft hole 41 to actuate the linking component (not shown) in the lock structure 4, so that the shaft 33 can control the lock head 40 to be inserted into or separated from the door hole 50 to open the door. It should be understood that the various specifications of the lock structure 4 are numerous, and the relative arrangement of the linkage components therein for actuating the lock head 40 can be designed according to the requirements without any particular limitation, and therefore, the detailed description thereof is omitted here for clarity.

When the door is locked, as shown in fig. 2, a key (not shown) is inserted into the keyhole 11 to drive the keyhole 11 to rotate, so that the lock head 40 is fixed in the door hole 50 (the lock head 40 cannot extend or retract relative to the door hole 50), thereby completing the locking operation. At this time, as shown in fig. 5A, the shift lever 16 drives the shift portion 311 to move toward the first positioning portion 13 (e.g., arrow Y1), so that the first position-limiting portion 312 of the driving member 31 abuts against the first positioning portion 13 of the housing 1a, and the actuating portion 314 of the driving member 31 is separated from the rotating member 34, so that the rotating member 34 is ejected out of the telescopic portion 341, and the telescopic portion 341 is separated from the shaft 33, so that the rotating member 34 does not drive the shaft 33 to rotate, i.e., the shaft 33 is stationary (e.g., cannot rotate).

Therefore, when the lock 40 is inserted into the door hole 50 and the rotating member 34 cannot interlock with the shaft member 33, the handle body 21 is pressed downward (in the force applying direction F1 shown in fig. 5A) to drive the driving member 22 to rotate (in the rotating direction R1 shown in fig. 5A), so that the wing portion 222 of the driving member 22 strikes (in the acting direction F2 shown in fig. 5A) the passive portion 321 of the pulling member 32 to move the pulling member 32 in the direction of the rotating member 34 (in the arrow direction Z shown in fig. 5A), at this time, the pulling member 32 can drive the rotating member 34 to rotate (in the rotating direction R2 shown in fig. 5A) by the engaging portion 322 engaging with the engaging portion 344, so that the handle body 21 can still rotate in the locked state, but the shaft member 33 is stationary and the lock 40 cannot be operated.

In other words, in the locked state (i.e. the lock head 40 is inserted into the door hole 50 or the rotating member 34 is ejected out of the retractable portion 341), the handle body 21 is in the idle rotation mechanism, i.e. the handle body 21 and the rotating member 34 are synchronously linked, but the shaft 33 is still and cannot actuate the lock head 40 of the lock structure 4 to disengage from the door hole 50, so that the door cannot be opened.

On the other hand, when the unlocking operation is performed, as shown in fig. 2, a key (not shown) is inserted into the keyhole 11 to release the lock cylinder 40 in the door hole 50 (the lock cylinder 40 is still located in the door hole 50), so as to complete the unlocking operation (the lock cylinder 40 can extend and retract relative to the door hole 50). At this time, as shown in fig. 5B and fig. 6, the toggle lever 16 drives the toggle portion 311 to move toward the second positioning portion 14 (as indicated by arrow Y2), so that the second position-limiting portion 313 of the driving member 31 abuts against the second positioning portion 14 of the housing 1a, and the actuating portion 314 of the driving member 31 is close to the rotating member 34 to cover and press the retractable portion 341 (as indicated by pressing direction P shown in fig. 6), so that the retractable portion 341 is reset and retracted (as indicated by displacement direction D shown in fig. 6) into the rotating member 34, so that the retractable portion 341 is engaged with the shaft 33, and thus the rotating member 34 and the shaft 33 can rotate synchronously.

Therefore, when the lock 40 is loose in the door hole 50, the handle body 21 is pressed downward (the force application direction F1 shown in fig. 5B) to drive the driving member 22 to rotate (the rotation direction R1 shown in fig. 5B), so that the wing portion 222 of the driving member 22 hits (the action direction F2 shown in fig. 5B) the passive portion 321 of the pulling member 32, so that the pulling member 32 drives the rotating member 34 to rotate (the rotation direction R2 shown in fig. 5B), and the rotating member 34 rotates the shaft 33 (the rotation direction R3 shown in fig. 5B), so that the lock 40 of the lock structure 4 is disengaged from the door hole 50 (i.e. the lock 40 is retracted into the lock structure 4) by the rotation of the shaft 33, and the handle body 21 can operate the lock structure 4 to open the door.

Fig. 7A and 7B are partial schematic views of a door lock device 7 according to a second embodiment of the present application. The difference between this embodiment and the first embodiment is the configuration of the handle structure 1 ″ and the other configurations are substantially the same, so the same parts will not be described below.

As shown in fig. 7A and 7B, the door lock device 7 is electrically controlled, so the acting component 3 of the handle structure 1 ″ can be configured with an electromagnetic element 35 disposed in the accommodating space S and an acting element 36 fixedly connected to the housing 1a and linking the electromagnetic element 35, and the acting element 36 is configured to match the rotating element 34 and the electromagnetic element 35, so that the telescopic portion 341 links the acting element 36.

In this embodiment, the electromagnetic element 35 can be an electromagnetic valve, and the acting element 36 is disposed around a partial circumference of the rotating member 34 to control the extending/retracting portion 341 to extend or retract into the rotating member 34. For example, one end of the acting element 36 is provided with a stop 361 corresponding to the displacement rod 345.

In addition, the cover 323 further has an opening 326 and a mounting hole 325, so that the abutting portion 36a of the acting element 36 is disposed through the opening 326, and the mounting hole 325 is provided for mounting the electromagnetic element 35.

When the locking operation is performed, the electromagnetic element 35 is energized to rotate the keyhole member 11 (not shown in the figure, but the electric locking mechanism is not shown), so that the lock head 40 is fixed in the keyhole 50, thereby completing the locking operation. At this time, the electromotive portion 351 of the electromagnetic element 35 retracts (in the retraction direction P1 shown in fig. 7B) to be away from the abutment portion 36a of the acting element 36.

Therefore, when the handle body 21 drives (as the force application direction F1 shown in fig. 7B) the driving member 22 to rotate (as the rotation direction R1 shown in fig. 7B), the wing 222 of the driving member 22 will hit (as the action direction F2 shown in fig. 7B) the passive portion 321 of the pulling member 32, so that the pulling member 32 drives the rotating member 34 to rotate (as the rotation direction R2 shown in fig. 7B), and when the displacement rod 345 slides out of the stopping portion 361, the rotating member 34 will eject the telescopic portion 341 (as the ejection direction P2 shown in fig. 7B), so that the telescopic portion 341 pushes away the stopping portion 361 to separate the shaft 33, and thus the rotating member 34 will not drive the shaft 33 to rotate, i.e. the shaft 33 is stationary. Therefore, the handle body 21 can still be operated in the locked state.

In summary, the door lock device 1,7 of the present application mainly uses the design of the extension portion 341 of the rotation member 34 to rotate the rotation member 34 when the handle body 21 is in the locked state, but the shaft member 33 does not rotate, so compared with the prior art, the door lock device 1 of the present application can perform the idle rotation mechanism when the handle body 21 is in the locked state, thereby preventing the handle body 21 from being damaged by being pulled by an external force when the handle body 21 is in the locked state.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
