The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-7, a cabinet lock handle clutch, includes handle 5, knurling shaft 6, lock body 8, rotary core 7, rotary core separation blade 1, separation and reunion pivot 2, separation and reunion round pin 4 and separation and reunion spring 3, handle 5 passes through knurling shaft 6 with rotary core 7 and is connected, rotary core separation blade 1 passes through the screw with rotary core 7 axial fixation on lock body 8, separation and reunion pivot 2 cup joints in rotary core 7 bottom, the outer wall of 2 one sides of separation and reunion pivot holes 21 has been opened to separation and reunion pivot 2, and separation and reunion round pin 4 inserts in the separation and reunion pivot hole 21 of locating, the cover is equipped with spring 3 on the separation and reunion round pin 4, rotary core 7 is close to separation and reunion round pin 4 one side outer wall and has been opened rotary core cavity 71, and the aperture of rotary core cavity 71 is greater than the diameter of spring 3, and rotary core cavity 71 and separation and reunion round pin 4 looks adaptation.

When the clutch pin 4 is completely pushed into the clutch rotating shaft 2, the clutch pin 4 is inserted into the cavity 71 of the rotating core 7, and at this time, the handle is in a clutch opening state, as shown in fig. 2, at this time, the handle 5 is rotated, the handle 5 drives the rotating core 7 to rotate, the rotating core 7 drives the clutch rotating shaft 2 to rotate through the clutch pin 4, and the clutch rotating shaft 2 drives the ground lever, the lock tongue piece and other structures to move, so that the unlocking function is realized; when the handle 5 is illegally pried, the clutch pin 4 is separated from the cavity 71 of the rotating core 7 under the action of the spring 3, the handle is in a clutch closing state at the moment, as shown in fig. 1, the handle 5 is rotated at the moment, the rotating core 7 idles along with the handle 5, but the clutch rotating shaft 2 cannot be driven to rotate, and the lock cannot be opened.

The utility model provides an adopt cabinet lock of this handle clutch, cabinet lock includes handle clutch and separation and reunion trigger bar 9, motor 10, motor carriage 11, spring bolt 12, spring bolt spring 13, lock core 14, lock core slide bar 15, motor 10 is fixed in on the lock body 8, motor carriage 11 is installed on motor 10's output shaft, and motor carriage 11 contacts with separation and reunion trigger bar 9, lock core slide bar 15 contacts with separation and reunion trigger bar 9, separation and reunion trigger bar 9 afterbody is equipped with boss 91, and separation and reunion trigger bar 9 tip is equipped with separation and reunion trigger bar head 92, it has spring bolt slot 121 to open on the spring bolt 12, boss 91 contacts with spring bolt slot 121, be equipped with projection 141 on the lock core 14, and open on the lock core slide bar 15 and have lock core slide bar groove 152, projection 141 contacts with lock core slide bar groove 152.

The working principle is as follows: after the cabinet lock receives an electric opening signal, the motor 10 rotates forwards, the motor sliding frame 11 arranged on the motor sliding frame moves leftwards to push the clutch trigger rod 9, the lug boss 91 at the tail part of the clutch trigger rod 9 pulls the bolt groove 121, so that the bolt 12 moves leftwards, the bolt tail part 122 is separated from the handle hole 51, and the handle 5 can be opened; meanwhile, the head 92 of the clutch trigger lever completely pushes the clutch pin 4 into the clutch rotating shaft hole 21, the handle clutch is in an open state at the moment, as shown in fig. 4, the handle 5 is rotated at the moment, and the clutch rotating shaft 2 and the heaven and earth rod and the ear piece connected with the clutch rotating shaft 2 can rotate together with the handle 5, so that the unlocking function is realized. When the cabinet lock receives an electric closing signal, the motor 10 rotates reversely, the motor sliding frame 11 arranged on the motor 10 moves rightwards, the bolt 12 moves rightwards under the action of the bolt spring 13, and the cabinet lock returns to a reset state; the bolt 12 pulls the clutch trigger rod 9 through the groove 121 contacted with the tail boss 91 of the clutch trigger rod, so that the clutch trigger rod 91 is reset; at the moment, the handle 5 is rotated, and when the clutch rotating shaft 2 rotates to a position corresponding to the locking state, the clutch pin 4 is popped up under the action of the clutch spring 3, namely, the handle is clutched and returned to the closing state. At this time, the handle 5 is pressed down, so that the bolt tail 122 can be pressed into the handle hole 51 to realize locking, as shown in fig. 3 and fig. 5.

When the key is used for unlocking, the key is used for rotating the lock cylinder 14, in the rotating process of the lock cylinder 14, the convex points 141 which are in contact with the grooves 151 in the lock cylinder sliding rod drive the lock cylinder sliding rod 15 to move left, the tail part 93 of the clutch trigger rod is pushed, the clutch trigger rod 9 is driven to move left, the tail boss 91 of the clutch trigger rod pulls the lock tongue groove 121, the lock tongue 12 moves left and is separated from the handle, and the handle 5 bounces off under the action of the torsion spring; meanwhile, the head 92 of the clutch trigger rod completely pushes the clutch pin 4 into the hole 21 of the clutch rotating shaft 2, so that the handle clutch is in an open state, the handle 5 is rotated at the moment, and the clutch rotating shaft 2 and the ground rod and the lug piece connected with the clutch rotating shaft can rotate together with the handle 5, thereby realizing the unlocking function. When the lock needs to be closed, the lock core sliding rod 15 moves rightwards under the driving of the return spring or the reverse rotation of the lock core, the lock tongue 12 moves rightwards under the action of the lock tongue spring 13, and returns to the corresponding position of the lock closing state; the bolt 12 pulls the clutch trigger rod 9 through the groove 121 contacted with the tail boss 91 of the clutch trigger rod, so that the clutch trigger rod 9 returns to the corresponding position of the locking state; at the moment, the handle 5 is rotated, and when the clutch rotating shaft 2 rotates to a position corresponding to the locking state, the clutch pin 4 is popped up under the action of the clutch spring 3, namely, the handle is clutched and returned to the closing state. At this time, the handle 5 is pressed down, so that the bolt tail 122 can be pressed into the handle hole 51 to realize locking, as shown in fig. 3 and 5.

When the handle 5 is illegally pried, the bolt tail part 122 is separated from the handle hole 51, the bolt 12 returns to the corresponding position of the locking state under the action of the bolt spring 13, meanwhile, the handle clutch is always in the closing state, the handle 5 is rotated at the moment, only the rotary core 7 connected with the handle 5 can be driven to rotate, but the clutch rotary shaft 2 cannot be driven to move all the time, and even if the handle 5 is illegally pried, the cabinet lock cannot be opened.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
