Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Referring to fig. 1 to 4, the door lock of the present invention comprises a panel 1 and a handle 3, wherein the panel 1 is provided with a mounting hole 11, and the mounting hole 11 is rotatably provided with a handle connecting sleeve 2. The rear end of the handle connecting sleeve 2 is fixedly connected with the handle 3 (the direction A is the front in the figure 1). Referring to fig. 6, a mating round hole 21 is formed in the front end of the handle connecting sleeve 2, a driving disc 22 is arranged in the front end of the handle connecting sleeve 2, and two driving protrusions 221 are arranged on the front side wall of the driving disc 22.
Referring to fig. 7, the door lock of the present invention includes a driving sleeve 4, the driving sleeve 4 rotatably penetrates through the mating round hole 21, the front end of the driving sleeve 4 is exposed out of the mating round hole 21, and the front end of the driving sleeve 4 is provided with a driving disc 41. The transmission disc 41 is provided with two avoidance long holes 411, and the avoidance long holes 411 are arc-shaped. Referring to fig. 8, the escape slots 411 are positioned on the rotational track of the driving protrusions 221, and each driving protrusion 221 passes through one of the escape slots 411. The avoidance slot 411 is used to avoid the driving bump 221 during the reverse rotation of the driving disc 22 (in this embodiment, the upward swinging direction of the handle 3 is defined as the forward direction, and the reverse direction is the reverse direction of the direction B1 in fig. 1 and 8). Specifically, as shown in fig. 6, the two driving protrusions 221 are uniformly distributed along the circumferential direction of the driving disc 22, correspondingly, as shown in fig. 7, the two avoidance long holes 411 are uniformly distributed along the circumferential direction of the driving disc 41, the central angle corresponding to the avoidance long holes 411 is 100 ° to 130 °, and in a normal state, the driving protrusions 221 are located in the middle part of the avoidance long holes 411 (as shown in fig. 8).
Specifically, as shown in fig. 8, the panel 1 is provided with an inner cavity, and two vertically opposite inner walls of the inner cavity are provided with limiting blocks 12. The handle connecting sleeve 2 is sleeved with a reset torsion spring 23, and two torsion spring ends 231 of the reset torsion spring 23 extend outwards. With reference to fig. 6, the rear side wall of the handle connecting sleeve 2 is provided with two torsion spring shifting blocks 24, and the two torsion spring shifting blocks 24 are uniformly distributed along the circumferential direction of the handle connecting sleeve 2.
In normal state (in combination with fig. 1, 8, 9): the handle 3 is in a transverse state, and the two torsion spring ends 231 of the return torsion spring 23 respectively abut against the respective lower sides of the two stopper blocks 12, and accordingly, the two torsion spring ends 231 of the return torsion spring 23 respectively abut against the respective lower sides of the two torsion spring dials 24. The transmission disc 41 is provided with two reset protrusions 44, the two reset protrusions 44 are uniformly distributed along the circumferential direction of the transmission disc 41, and the two reset protrusions 44 extend backwards. Normally, both return tabs 44 rest against the respective undersides of the two torsion spring ends 231.
Taking fig. 8 as an example, in swinging the handle 3 from the lateral state in the forward direction (direction B1 in fig. 1, 8) to the obliquely upward direction, the two torsion spring dials 24 are rotated accordingly. Since the two torsion spring ends 231 of the restoring torsion spring 23 respectively abut against the respective lower sides of the two stoppers 12, the torsion spring shifting block 24 on the left side in fig. 8 drives the torsion spring end 231 on the left side in fig. 8 to swing toward the direction B1, and the torsion spring end 231 on the right side in fig. 8 is still abutted against the stopper 12 on the right side in fig. 8, so that the restoring torsion spring 23 is further elastically deformed. When the handle 3 is released, the reset torsion spring 23 resets under the action of its own elastic restoring force, the torsion spring end 231 on the left side in fig. 8 is restored to abut against the stopper 12 on the left side in fig. 8, and pushes the torsion spring shifting block 24 on the left side in fig. 8 to drive the handle connecting sleeve 2 to swing together with the handle 3 to a state as shown in fig. 8, namely, a state in which the handle 3 is arranged along the transverse direction. In this process, the torsion spring end 231 on the left side in fig. 8 abuts against the reset bump 44 on the left side in fig. 8 to drive the driving sleeve 4 to reset to the state shown in fig. 8, so as to drive the driving rod 6 to reset to the state shown in fig. 8.
Since the two torsion spring shifting blocks 24 are uniformly distributed along the circumferential direction of the handle connecting sleeve 2, in the process of swinging the handle 3 from the transverse state to the downward inclination (in the reverse direction of the direction B1 in fig. 1 and 8), the torsion spring shifting block 24 on the right side in fig. 8 drives the torsion spring tail end 231 on the right side in fig. 8 to swing in the reverse direction of the direction B1, and similarly, when the handle 3 is released, the reset torsion spring 23 is reset under the action of the self elastic restoring force so as to drive the handle 3 to reset to the transverse state (as shown in fig. 8). I.e. the return torsion spring 23 allows the handle 3 to automatically return to the transverse state after swinging upwards or downwards.
As an alternative embodiment (this alternative embodiment is not shown, reference may be made to fig. 1, 8), in the normal state: when the handle 3 is in the lateral state, the two torsion spring ends 231 of the return torsion spring 23 respectively abut against the respective upper sides of the two stoppers 12, accordingly: the two torsion spring ends 231 of the return torsion spring 23 respectively abut against the respective upper sides of the two torsion spring dials 24, and the two torsion spring ends 231 of the return torsion spring 23 respectively abut against the respective upper sides of the two return bumps 44. In this way, the handle 3 can be reset to the horizontal state after being swung to be inclined.
Referring to fig. 1 to 5 and 8, the door lock of the present invention includes a transmission plate 5 and a transmission rod 6. The front end of the driving sleeve 4 is provided with a first driving profiling hole 42 (combining 7 figures). Referring to fig. 3 and 8, the driving plate 5 includes a main body 51 and a protruding portion 52, and the main body 51 is provided with a second driving contour hole 511. The cross-sectional profile of the drive rod 6 is non-circular, in this embodiment the cross-section of the drive rod 6 is square. The profile of the first and second drive profiling holes 42, 511 both correspond to the cross-sectional profile of the drive rod 6. The driving plate 5 is stacked on the front side wall of the driving disc 41, specifically, in connection with fig. 12, the panel 1 is screwed with the cover plate 13, and after the cover plate 13 is installed, the cover plate 13 abuts against the front side wall of the driving plate 5, so that the driving plate 5 is kept stacked on the front side wall of the driving disc 41. The drive rod 6 passes through the second drive profiling aperture 511 to be partially within the first drive profiling aperture 42. The protruding portion 52 is located on the rotation track of the driving bump 221 and abuts against one of the driving bumps 221 (refer to fig. 7 and 8).
The exposed end of the transmission rod 6 is connected with a lock cylinder (not shown), and the lock cylinder can be locked or unlocked by rotating the transmission rod 6.
Specifically, as shown in fig. 8 and 9, the main body 51 of the driving plate 5 has a partial circular shape, the protruding portion 52 of the driving plate 5 has a partial fan shape, and the circular arc of the protruding portion 52 and the circular arc of the main body 51 are concentric with each other. The front side wall of the driving disc 41 is provided with an outer limit flange 412 and an inner limit flange 413. The inner limit flange 413 is arc-shaped, and the inner wall profile of the inner limit flange 413 is adapted to the partial circular shape of the main body 51. The outer limit flange 412 is annular, and the contour of the inner wall of the outer limit flange 412 is adapted to the arc of the protruding portion 52. The inner and outer limit flanges 413, 412 cooperate to guide the drive plate 5 so that the drive plate 5 can rotate relative to the drive disk 41, and the cover 13 abuts the drive plate 5 (see fig. 12) so that the drive plate 5 is held between the inner and outer limit flanges 413, 412.
Specifically, referring to fig. 8 and 9, the central angle corresponding to the protruding portion 52 is 85 ° to 95 °, when the protruding portion 52 abuts against one of the driving protrusions 221, the second driving profiling hole 511 formed in the main body portion 51 and the first driving profiling hole 42 formed in the driving sleeve 4 are aligned with each other.
Thus, also taking fig. 8 as an example, in the process of swinging the handle 3 forward (in the direction B1 in fig. 1 and 8) to the inclined upward direction, the driving lug 221 located at the lower side in fig. 8 drives the driving rod 6 and the driving sleeve 4 to rotate together forward through the driving plate 5 (the protruding portion 52), so as to lock the lock cylinder. During the reverse swing of the handle 3 (reverse direction of the direction B1 in fig. 8), the avoidance long hole 411 avoids the driving projection 221 during the rotation of the handle connecting sleeve 2, and the driving projection 221 does not contact with the protruding portion 52 (the driving projection 221 idles), so that the handle 3 cannot drive the transmission sleeve 4 and the transmission rod 6 to rotate through the transmission sheet 5, and thus the handle 3 cannot swing in the reverse direction (swing downward), and unlocking cannot be achieved. For the door with the peep hole, the peep hole is likely to be broken and detached by an lawbreaker, and then the peep hole is used for making a work in a deep manner indoors, so that the door lock is unlocked. With the door lock of the present invention, when the owner closes the door in the room to lock, the owner can lock the door by swinging the transverse handle 3 to the upward inclination (i.e., in the direction B1 in fig. 8). After locking, if there is an illegal molecule to break and tear the cat eye, then stretch into the case making tool through the cat eye hole to when stirring handle 3 and swing downwards (i.e. along the opposite direction of direction B1 in FIG. 8), dodge slot 411 dodge drive lug 221 at handle adapter sleeve 2 counter-rotating's in-process as previously described, make drive lug 221 idle running, make handle 3 can't drive sleeve 4 and transfer line 6 rotation through drive piece 5, therefore the illegal molecule is difficult to simply stir handle 3 through cat eye Kong Fanxiang (facing downwards) and realize unblanking.
Specifically, the cross section profile of the rear section of the handle connecting sleeve 2 is square, a square cavity is formed in the handle 3, the rear section of the handle connecting sleeve 2 is matched with the square cavity, and the square cavity and the rear end of the handle connecting sleeve 2 are fixedly connected with each other through a screw 34.
In connection with fig. 12, the cover 13 is provided with a "left open" mark and a "right open" mark, the front side wall of the driving plate 5 is provided with an indication arrow, and when the driving plate 5 is adjusted to the state in which the indication arrow points to the "left open" mark (corresponding to the state shown in fig. 9), the protruding portion 52 abuts against one of the driving protrusions 221 (the driving protrusion 221 on the upper side in fig. 9), and at this time, the door lock is adapted to the door-loading form of "left open" (as shown in fig. 11). When the transmission piece 5 is adjusted to the state where the indication arrow points to the "right open" sign (corresponding to the state shown in fig. 8, 12), the projection 52 abuts against the other one of the drive lugs 221 (the drive lug 221 on the lower side in fig. 8), and at this time, the door lock is adapted to the door-loading form of "right open" (as shown in fig. 10).
In order to adapt to different door lock setting positions of different doors, the door lock of the present invention can be correspondingly deformed, specifically, if the door lock needs to be installed in a form of "right open" as shown in fig. 10 (the left side edge of the door panel is a hinge shaft, and the door lock is installed on the right side of the inner wall of the door panel), the handle 3 and the driving piece 5 are installed in a form as shown in fig. 1 to 5 and fig. 8, wherein the indication arrow of the driving piece 5 is aligned with the "right open" sign of the cover plate 13. If it is required to install the door lock in a "left open" form as shown in fig. 11 (the right side edge of the door panel is the hinge shaft, and the door lock is installed at the left side of the inner wall of the door panel), the handle 3 and the driving piece 5 are installed in a form as shown in fig. 9.
The right opening mode is adjusted to be the left opening mode, the cover plate 13, the transmission rod 6, the transmission sheet 5 and the transmission sleeve 4 are detached in sequence, then the screw 34 is detached, the handle 3 can be detached from the rear end of the handle connecting sleeve 2, then the handle 3 is rotated 180 degrees (the angle shown in fig. 8 is rotated to the angle shown in fig. 9), the handle connecting sleeve 2 is reinstalled, and then the screw 34 is screwed again to fixedly connect the handle connecting sleeve 2 with the handle 3 again. Further, the driving sleeve 4 is reinstalled (as shown in fig. 9), the driving plate 5 is replaced on the front side of the driving disc 41, and the indication arrow of the driving plate 5 is aligned with the "left open" mark of the cover plate 13, at this time, the driving plate 5 is adjusted such that the protruding portion 52 abuts against the driving protrusion 221 (as shown in fig. 9) on the upper side in fig. 9, and the second driving profiling hole 511 formed in the main body portion 51 and the first driving profiling hole 42 formed in the driving sleeve 4 are aligned with each other. Then, the transmission rod 6 passes through the second transmission profiling hole 511 and partially enters the first transmission profiling hole 42, and finally the cover plate 13 is installed, so that the door lock is adjusted from the right-opening mode to the left-opening mode.
Referring to fig. 9 and 11, for a door lock of the "left open" type, the direction in which the handle 3 swings upward is defined as the forward direction (i.e., direction B2 in fig. 9 and 11), and in the process of swinging the handle 3 forward, the driving bump 221 on the upper side in fig. 9 pushes the protruding portion 52 to drive the transmission rod 6 and the transmission sleeve 4 to rotate forward together, so as to unlock the door. When the "right-opening" and "left-opening" are adopted, the unlocking directions of the lock cylinder are opposite, and the directions are the direction B1 in fig. 10 and the direction B2 in fig. 11, respectively. For the door lock of the "left open" type, in the process of reversely swinging the handle 3, the avoidance long hole 411 avoids the driving projection 221 in the process of rotating the handle connecting sleeve 2, and the driving projection 221 is not in contact with the protruding portion 52 (the driving projection 221 idles), so that the transmission sleeve 4 and the transmission rod 6 cannot be driven to rotate by the transmission sheet 5, and thus, the handle 3 reversely swings and unlocking cannot be realized.
The arrangement of the driving lug 221, the avoiding long hole 411 and the transmission piece 5 can enable the handle 3 to effectively transmit when swinging in the forward direction, so that locking is realized, and the transmission fails when swinging in the reverse direction, so that unlocking cannot be realized. In addition, the driving lug 221, the avoiding long hole 411, the driving piece 5 and the connection mode of the handle 3 and the handle connecting sleeve 2 enable the door lock to be conveniently adjusted to be in a right-opening or left-opening mode so as to adapt to doors with different installation modes.

Referring to fig. 6, the sidewall of the handle connecting sleeve 2 is provided with a through slot 25, and is communicated with the mating round hole 21 through the slot 25. The number of the through holes 25 is two, and the two through holes 25 are respectively arranged on two opposite side walls of the rear section of the hand connecting sleeve. Referring to fig. 7, the rear end of the driving sleeve 4 is provided with two driving notches 43, and the two driving notches 43 are uniformly distributed along the circumferential direction of the driving sleeve 4. The number of the lock bars 32 is two, each of which is matched with one lock bar 32 through the long hole 25, and each of the transmission notches 43 is matched with one lock bar 32. The cross section of the lock lever 32 is square, and the dimension between the two opposite inner walls of the transmission notch 43 is matched with the lock lever 32 by the dimension between the two opposite inner walls of the long hole 25 being matched with the lock lever 32.
The lock lever 32 can be partially passed through the long hole 25 into the transmission notch 43. When the lock lever 32 is partially pushed into the transmission notch 43 by the push button 31 (see fig. 4 and 5), and the handle 3 is reversely swung (i.e., in the opposite direction of the direction B1 in fig. 8 or in the opposite direction of the direction B2 in fig. 9), the handle 3 drives the transmission lever 6 to reversely rotate by the lock lever 32 to unlock.
