The inner unlocking frame also has a protrusion extending in a direction close to the protrusion, and the protrusion is located on the displacement path of the protrusion. The protrusion drives the abutment frame to rotate by abutting against the protrusion.
[0010] By adopting the above technical solution, the unlocking component is set so that when the lock tongue needs to be unlocked from the inside of the door, it is only necessary to drive the inner unlocking frame to rotate so that the protrusion on the inner unlocking frame can abut against the protrusion on the abutting frame, thereby pushing the abutting frame to rotate through the abutting, so that the abutting frame rotates to a state where it is not located on the displacement path of the locking portion, thereby achieving the unlocking of the lock tongue and effectively facilitating the driving of the abutting frame to reset.
[0011] Preferably, the lock tongue is further provided with an abutment portion, one end of the inner unlocking frame extends toward the abutment portion and abuts against the abutment portion to drive the lock tongue to rotate, and the other end of the inner unlocking frame extends out of the mounting frame.
[0012] By adopting the above technical solution, the inner unlocking frame and the abutting portion are arranged to abut against each other, so that when the door needs to be opened from the inside, during the process of the inner unlocking frame rotating to drive the abutting frame to reset, the inner abutting frame can abut against the abutting portion on the lock tongue, thereby driving the lock tongue, so that when the inner unlocking frame rotates, it can drive the abutting frame to reset and the lock tongue to rotate, thereby realizing unlocking between the door and the door frame, which effectively facilitates the user to open the door.
[0013] Preferably, a switch portion is further provided on the inner unlocking frame, and the unlocking assembly further comprises an outer unlocking frame, which is rotatably connected to the mounting frame, and the outer unlocking frame drives the inner unlocking frame to rotate by abutting against the switch portion.
[0014] By adopting the above technical solution and setting the external unlocking frame, the user can drive the external unlocking frame to rotate through the door handle when outside the door, so that the external unlocking frame abuts against the switch part, driving the internal unlocking frame to rotate, thereby realizing the reset of the abutting frame and the rotation of the lock tongue, realizing the unlocking of the door and the door frame outside the door, effectively facilitating the use of the user, and at the same time improving the safety of the door handle lock of the present application.
[0015] Preferably, the anti-theft frame further has a driving portion extending in a direction close to the abutment frame, and a driving groove is penetrated through the side wall of the abutment frame. The driving portion extends into the driving groove and drives the abutment frame to rotate by abutting against the inner wall of the driving groove.
[0016] By adopting the above technical solution and arranging the driving part and the driving groove, when the anti-theft frame rotates, the driving part on the anti-theft frame can drive the abutment frame to rotate by abutting against the inner wall of the driving groove, so that the abutment frame is located on the displacement path of the locking part, thereby realizing the driving of the abutment frame, thereby ensuring the driving effect of the anti-theft frame on the abutment frame.
[0017] Preferably, a limiting frame is further provided on the mounting frame, and the limiting frame is located at a side of the locking portion away from the abutting frame, and the limiting frame limits the locking portion by abutting against the locking portion.
[0018] By adopting the above technical solution, the setting of the limit frame enables the limit frame to limit the lock tongue by abutting against the limit part, thereby reducing the probability that the abutment part itself is no longer located on the displacement path of the inner unlocking frame due to the lock tongue rotating at an excessively large angle, thereby ensuring that the inner unlocking frame drives the lock tongue to rotate and ensuring the normal use of the present application.
[0019] Preferably, a reset spring is further provided on the mounting frame, and the reset spring is used for resetting the abutment frame.

[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The present application embodiment discloses an anti-theft door handle lock for an outer door. Figure 1 and Figure 2 The outer door anti-theft door handle lock includes a mounting frame 1, a lock tongue 2 and an unlocking assembly 3. The lock tongue 2 is rotatably connected to the mounting frame 1, and a locking portion 21 is provided on the lock tongue 2. The mounting frame 1 is also provided with an anti-theft assembly 4, which includes an anti-theft frame 41 and an abutting frame 42. Both the anti-theft frame 41 and the abutting frame 42 are rotatably connected to the mounting frame 1. One end of the anti-theft frame 41 extends out of the mounting frame 1, and is used to drive itself to rotate after abutting against the door frame. The anti-theft frame 41 drives the abutting frame 42 to rotate, so that the abutting frame 42 is located on the displacement path of the locking portion 21.
[0034] Reference Figure 1 and Figure 2 The mounting frame 1 is provided with a shell, and the shell is fixedly connected to the mounting frame 1 by bolts. The mounting frame 1 is used to be fixedly installed in the door, and the top of the lock tongue 2 (with the attached Figure 2 The position in the middle is the direction) and is rotatably connected to the mounting frame 1 through a pin shaft, and the bottom end of the lock tongue 2 extends out of the mounting frame 1 and is tilted. The top end of the lock tongue 2 is close to the side inside the mounting frame 1, and an abutment portion 22 is extended, and the abutment portion 22 is integrally formed with the lock tongue 2.
[0035] Reference Figure 1 and Figure 2 An elastic torsion spring 5 is also sleeved on one end of the pin shaft that rotatably connects the lock tongue 2 and the mounting frame 1. One end of the elastic torsion spring 5 abuts against the lock tongue 2, and the other end abuts against the mounting frame 1 to reset the lock tongue 2 and ensure the normal use of the lock tongue 2.
[0036] Reference Figure 2 and Figure 3The locking portion 21 is located on a side wall of the bottom end of the lock tongue 2 close to the abutment frame 42, and the locking portion 21 is fixedly connected to the lock tongue 2. A limiting frame 11 is also provided on the bottom end of the mounting frame 1, and the limiting frame 11 is integrally formed with the mounting frame 1. The mounting frame 1 is located on a side of the locking portion 21 away from the abutment frame 42, and abuts against the locking portion 21 to limit the rotation of the lock tongue 2, thereby reducing the probability of the lock tongue 2 rotating at an excessive angle under the elastic force of the elastic torsion spring 5.
[0037] Reference Figure 2 and Figure 3 The top of the anti-theft frame 41 is rotatably connected to the mounting frame 1 through a pin shaft, and the anti-theft frame 41 and the lock tongue 2 share the same rotation pin shaft to ensure stability during rotation. A reset torsion spring 6 is sleeved on the end of the pin shaft away from the elastic torsion spring 5, one end of the reset torsion spring 6 abuts against the mounting frame 1, and the other end of the reset torsion spring 6 abuts against the anti-theft frame 41. The reset torsion spring 6 is used to reset the anti-theft frame 41 to ensure the normal use of the anti-theft frame 41.
[0038] Reference Figure 3 and Figure 4 The bottom end of the anti-theft frame 41 extends obliquely downward out of the mounting frame 1. A limiting protrusion 411 extends downward from the bottom end of the anti-theft frame 41, and the limiting protrusion 411 is integrally formed with the anti-theft frame 41. The limiting protrusion 411 is located on the side of the limiting frame 11 close to the abutting frame 42, and the limiting protrusion 411 abuts against the side wall of the abutting frame 42 to reduce the probability of the abutting frame 42 rotating too much under the elastic force of the return torsion spring 6, thereby ensuring the normal use of the abutting frame 42.
[0039] Reference Figure 2 A driving part 412 is further extended on the side wall of the anti-theft frame 41 close to the lock tongue 2. The driving part 412 is integrally formed with the anti-theft frame 41 and is located on the side of the anti-theft frame 41 away from the lock tongue 2. The abutment frame 42 is rotatably connected to the mounting frame 1 through a pin shaft, and the rotation axis of the abutment frame 42 is arranged parallel to the rotation axis of the anti-theft frame 41.
[0040] Reference Figure 2 A driving groove 7 is also formed on the side wall of the end of the abutting frame 42 near the lock tongue 2, and the driving portion 412 extends into the driving groove 7 and abuts against the inner wall of the driving groove 7, so that the driving portion 412 drives the abutting frame 42 to rotate by abutting against the inner wall of the driving groove 7. The bottom of the end of the abutting frame 42 near the lock tongue 2 is concave and has an arc surface, so as to reduce the wear between the locking portion 21 and the abutting frame 42 when abutting against the locking portion 21.
[0041] Reference Figure 1 and Figure 2In the initial state, that is, when the door is in the open state and the anti-theft frame 41 does not rotate, the driving part 412 is located at the bottom of the driving groove 7. When the anti-theft frame 41 abuts against the door frame, so that the bottom end of the anti-theft frame 41 rotates toward the mounting frame 1, the driving part 412 on the anti-theft frame 41 moves together with the anti-theft frame 41, so that the abutment point between the driving part 412 and the inner wall of the driving groove 7 changes, thereby driving the end of the abutting frame 42 close to the lock tongue 2 to rotate downward through the abutment, so that the concave part at the bottom end of the abutting frame 42 is located on the displacement path of the locking part 21.
[0042] Reference Figure 2 and Figure 4 , a hook portion 421 is also provided on the bottom end of the abutment frame 42 away from the lock tongue 2, and the hook portion 421 is integrally formed with the abutment frame 42. A hook frame 12 is also provided on the inner side wall of the mounting frame 1 close to the hook portion 421, and the hook frame 12 is integrally formed with the mounting frame 1. A reset spring 8 is also provided on the mounting frame 1, and in the embodiment of the present application, the reset spring 8 is a tension spring. One end of the reset spring 8 is sleeved on the hook portion 421, and the other end of the reset spring 8 is sleeved on the hook frame 12, so that when the abutment frame 42 rotates, it can drive the reset spring 8 to be compressed or stretched to reset the abutment frame 42.
[0043] Reference Figure 4 The unlocking assembly 3 includes an inner unlocking frame 31 and an outer unlocking frame 32. The inner unlocking frame 31 is rotatably connected to the mounting frame 1 via a pin shaft, and the rotation axis of the inner unlocking frame 31 is arranged parallel to the rotation axis of the lock tongue 2. One end of the inner unlocking frame 31 is bent upward and extends in a direction close to the lock tongue 2, and finally abuts against the bottom end of the abutting portion 22 on the lock tongue 2, so that when the inner unlocking frame 31 rotates, it can drive the lock tongue 2 to rotate by abutting.
[0044] Reference Figure 4 On the side of the inner unlocking frame 31 close to the abutting frame 42, a protrusion 311 extends obliquely upward. The protrusion 311 is integrally formed with the inner unlocking frame 31, and a guide surface is provided on the top of the protrusion 311 to reduce the wear of the protrusion 311. On the side wall of the abutting frame 42 close to the inner unlocking frame 31, a protrusion 422 extends in the direction close to the abutting frame 42. The protrusion 422 is integrally formed with the abutting frame 42, and the bottom end of the protrusion 422 abuts against the protrusion 311, so that when the inner unlocking frame 31 rotates, it can drive the abutting frame 42 to rotate by abutting against the protrusion 422.
[0045] Reference Figure 1 , Figure 2 and Figure 4In the initial state, the lock tongue 2 extends out of the mounting frame 1, and the bottom end of the anti-theft frame 41 is located inside the mounting frame 1, that is, when the abutting portion 22 performs a limit lock on the lock tongue 2, the end of the abutting frame 42 abuts against the bottom end of the abutting portion 22 on the lock tongue 2, and the protrusion 311 on the abutting frame 42 abuts against the protrusion 422 on the abutting frame 42. When the end of the inner unlocking frame 31 close to the lock tongue 2 rotates upward, the protrusion 311 pushes the protrusion 422 to make the end of the abutting frame 42 close to the lock tongue 2 rotate upward. At this time, the rotation angle of the abutting frame 42 is greater than the rotation angle of the anti-theft frame 41 driving the abutting frame 42, so that the bottom end of the abutting frame 42 is no longer located on the displacement path of the locking portion 21 on the lock tongue 2, thereby achieving the unlocking of the lock tongue 2. During this process, the end of the inner unlocking frame 31 moves upward by pushing the abutment portion 22 on the lock tongue 2, thereby causing the lock tongue 2 to rotate, so that the bottom end of the lock tongue 2 gradually rotates into the mounting frame 1, thereby driving the lock tongue 2.
[0046] Reference Figure 1 and Figure 4 The end of the inner unlocking frame 31 away from the lock tongue 2 is extended obliquely upward and extends out of the mounting frame 1. The end of the inner unlocking frame 31 away from the lock tongue 2 is used to connect with other structures in the door, so that the user can drive the end of the inner unlocking frame 31 to rotate downward through other structures (the position in the figure indicates the direction, and in actual use, it is determined according to the specific installation position and direction) to achieve the driving of the inner unlocking frame 31.
[0047] Reference Figure 1 and Figure 4 A switch portion 312 is further extended downward from the bottom of the inner unlocking frame 31, and the switch portion 312 is integrally formed with the inner unlocking frame 31. The outer unlocking frame 32 is rotatably connected to the mounting frame 1, and the rotation axis of the outer unlocking frame 32 is perpendicular to the rotation axis of the inner unlocking frame 31. A push portion 321 is further extended upward from the top of the outer unlocking frame 32, and the push portion 321 is integrally formed with the outer unlocking frame 32, and the push portion 321 is located at the end of the switch portion 312 away from the lock tongue 2.
[0048] Reference Figure 1 and Figure 4 The outer wall of one end of the push portion 321 close to the lock tongue 2 abuts against the side wall of the switch portion 312, so that when the outer unlocking frame 32 rotates, the push portion 321 abuts against the switch portion 312, so that the switch portion 312 drives the inner unlocking frame 31 to rotate, thereby unlocking and driving the lock tongue 2.
[0049] Reference Figure 1 and Figure 4One end of the outer unlocking frame 32 extends to the outside of the mounting frame 1 in a direction away from the inner unlocking frame 31. The outer unlocking frame 32 extends to a side wall outside the mounting frame 1, and a cross hole 9 is formed through it. The cross hole 9 is used for inserting a frame body on the door handle that drives the outer unlocking frame 32 to rotate, so that after the user inserts the key into the door handle, the outer unlocking frame 32 can be driven to rotate through the structure inside the door handle to unlock and drive the lock tongue 2, so that the user can open the door smoothly later.
[0050] The implementation principle of an anti-theft door handle lock for an outer door in an embodiment of the present application is as follows: when the door is gradually closed, the anti-theft frame 41 gradually abuts against the door frame, so that the bottom end of the anti-theft frame 41 rotates toward the mounting frame 1, so that the driving part 412 on the anti-theft frame 41 is displaced together with the anti-theft frame 41, thereby changing the abutment between the driving part 412 and the inner wall of the driving groove 7, thereby driving the end of the abutment frame 42 close to the lock tongue 2 to rotate downward, so that the recessed part at the bottom end of the abutment frame 42 is located on the displacement path of the locking part 21, thereby realizing the limited locking of the lock tongue 2, and reducing the probability of unscrupulous elements opening the door by prying the lock with a card.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
