The driving turntable 3 is fixedly arranged at the front end of the mounting sleeve 21, and the driving turntable 3 can be detached from the mounting sleeve 21, specifically, with reference to fig. 5 and 6, the driving turntable 3 is provided with a central circular hole 32, and the hole wall of the central circular hole 32 is provided with an insertion block 33. The front end of the mounting sleeve 21 is provided with a slot 211 arranged along the axial direction, and the insertion block 33 is detachably inserted and matched with the slot 211. Referring to fig. 7, the front end of the mounting sleeve 21 is connected to a limiting piece 8 through a thread, and the limiting piece 8 abuts against the front wall of the driving turntable 3 to keep the insertion block 33 in the insertion slot 211.
Referring to fig. 7, the driven turntable 4 is located at the front side of the driving turntable 3, an insertion cylinder 41 is fixedly disposed at the rear end surface of the driven turntable 4, and the insertion cylinder 41 is rotatably inserted into the mounting sleeve 21. The front end face of the driven turntable 4 is provided with a square hole 44, the square hole 44 extends to the inside of the insertion cylinder 41, the square hole 44 is used for installing a transmission column (not shown in the figure), and the rotation of the transmission column can drive a lock block (not shown in the figure) to slide so as to realize locking or unlocking. The driven turntable 4 is provided with two arc-shaped avoiding long holes 42. The driving turntable 3 is in threaded connection with a limiting piece 5, and the limiting piece 5 is locally positioned in the arc-shaped avoiding long hole 42.
Specifically, with reference to fig. 5 to 7, the door lock includes a torsion spring 7, and the torsion spring 7 is sleeved outside the mounting sleeve 21. The inner wall of the housing 1 is provided with two limiting parts 11 (see fig. 2), the two ends of the torsion spring 7 are respectively provided with extending strips 71, each extending strip 71 abuts against one limiting part 11, and the two extending strips 71 abut against the lower side of the limiting part 11.
Specifically, with reference to fig. 2 to 4, the edge of the driven turntable 4 is provided with two second reset dials 43 extending rearward, each extension bar 71 matches with one second reset dial 43, and in the initial state, the second reset dials 43 are all abutted against the upper side of the extension bar 71.
Specifically, with reference to fig. 2 to 4, a first reset moving block 31 is disposed on the rear side of the driving turntable 3, the limiting member 5 is a screw, the tail of the screw penetrates the rear side of the driving turntable 3, the first reset moving block 31 and the tail of the screw are respectively matched with an extending strip 71, and in an initial state, the tails of the first reset moving block 31 and the screw are both abutted against the upper side of the extending strip 71.
Specifically, referring to fig. 4, the limiting member 5 is a socket head cap screw, and the contour of the circumferential surface of the head portion of the socket head cap screw is matched with the contour of the end portions of the two inner side walls of the arc-shaped avoiding long hole 42.
Specifically, the two arc-shaped avoidance long holes 42 have the same shape and are uniformly arranged along the lower half circumferential edge of the driven turntable 4.
In the initial state, the handle 2 is disposed in the horizontal direction (refer to fig. 10, 11). In the process that the driving turntable 3 rotates in the forward direction (refer to the direction N in fig. 4 and 9, i.e. the direction in which the handle 2 swings upward), the driving turntable 3 pushes the driven turntable 4 to rotate through the limiting member 5, so as to drive a transmission column (not shown) arranged on the driven turntable 4 to rotate, thereby realizing locking. In the process that the driving turntable 3 rotates reversely (namely, in the direction that the handle 2 swings downwards), the arc-shaped avoiding long hole 42 avoids the limiting part 5, and the driven turntable 4 (transmission column) does not rotate, so that unlocking cannot be realized by only swinging the handle 2 downwards.
Referring to fig. 5 to 8, the mounting sleeve 21 is slidably provided with a push button 6, the push button 6 being slidable into a plug-in fit with the insertion cylinder 41. Specifically, the button 6 comprises a cap 61 and a connecting block 62, the cap 61 is fixedly connected with the connecting block 62, and specifically, the cap 61 is provided with a square cavity 612. The connecting block 62 is provided with a square projection which is matched with the square cavity 612. The connecting block 62 is penetrated with a screw which penetrates out from the rear end of the square bump and is in threaded connection with the cap 61.
The side wall of the cap 61 is provided with a sliding groove 611, the inner wall of the mounting sleeve 21 is provided with a limiting block 212, and the limiting block 212 is slidably matched with the sliding groove 611, so that the relative rotation of the cap 61 and the handle 2 is limited. The connecting block 62 is provided with an insertion portion 621, and the rear end of the insertion cylinder 41 is provided with an insertion groove 45. When the insertion portion 621 enters the insertion slot 45, the handle 2 can drive the driven rotary plate 4 to rotate, that is, after the button 6 is pressed, the handle 2 (making the handle 2 swing downwards) can drive the driven rotary plate 4 (transmission column) to rotate in the opposite direction of the N direction, so as to realize unlocking. Because must press button 6 earlier to make insertion portion 621 get into insertion groove 45, just can drive driven turntable 4 through handle 2 and realize the unblock towards the opposite direction rotation of N direction, the tool to lock of this application can improve lawless persons and stretch into the degree of difficulty that the instrument was unlocked through the cat eye hole, thereby improves the security.
The handle orientation of the lock can be adjusted according to the door opening mode (left opening or right opening) of the door panel to be locked, that is, the lock can be switched between the two states shown in fig. 4 and 9, and the specific operation is as follows: the cover plate 12 (see fig. 1) is detached, the driven turntable 4 is detached, the spacing piece 8 is detached from the mounting sleeve 21, and the driving turntable 3 is detached. Then, the driving turntable 3 and the handle 2 are rotated for half a circle, and then the rest parts are installed again according to the original state, namely the direction of the handle is switched.
At the in-process that switches the handle orientation, only need to lift spacing piece 8, driven turntable 4 off, then will take the initiative carousel 3 and handle 2 rotates the half-cycle, then the equipment again, can realize the switching of tool to lock state, the part that should switch the in-process and involve is less for it is simple and easy, convenient to switch the process, makes the installation of tool to lock more convenient.
As an alternative embodiment, the arc-shaped avoiding long hole 42 may be replaced by an arc-shaped avoiding groove (not shown), the limiting member 5 is located in the arc-shaped avoiding long hole 42, and the arc-shaped avoiding groove can play a similar role as the arc-shaped avoiding long hole 42.
As an alternative embodiment (not shown), both extension bars 71 abut against the upper side of the stopper portion 11. Both second reset dials 43 abut the underside of the extension bar 71. The first reset moving block 31 and the tail of the screw are both against the lower side of the extension bar 71.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
