Example 1:

as shown in fig. 1, the utility model discloses a broken dismouting of door lock is put, including broken head, pinch bar 3 and broken lock handle 4 of tearing open.

The breaking head is fixedly connected to one end of the pry bar 3 and can be welded or integrally formed. The breaking-in head is provided with at least one first U-shaped groove 51, and the opening direction of the first U-shaped groove 51 is parallel to the extending direction of the pry bar 3. As shown in fig. 2a, since the door handle 11 is fixed on the lock cylinder cover plate 12 in an L-shape, when breaking, the first U-shaped groove 51 of the breaking head is clamped at the root of the door handle 11 from below, the opening end of the first U-shaped groove 51 abuts against the door panel 1 or the lock cylinder cover plate 12, and the middle part of one side abuts against the lateral part of the door handle 11, at this time, the other end of the pry bar 3 is held to apply a force in a direction away from the door panel 1, so as to form a large force prying the door handle 11, so that the door handle 11 is separated from the door panel 1 or the lock cylinder cover plate 12, and the lock cylinder cover plate 12 and even the whole lock are damaged. As shown in fig. 2b, another way of prying the door handle by using the device is to extend the breaking head into the gap between the transverse part of the door handle and the door panel, and hold the other end of the prying bar 3 to apply force in the direction away from the door panel 1, at this time, the interference length between the breaking head and the door handle is no longer limited to the groove depth of the first U-shaped groove, and the interference length can be adjusted according to different doors and door handles to form a proper force arm length.

With continued reference to fig. 1, in this embodiment the breaking head comprises two prongs 21, the two prongs 21 forming a U-shaped slot 5 therebetween. The fork teeth 21 extend along the direction parallel to the axis of the pry bar 3, and have gradually thinner thickness and gradually larger width, so that the fork teeth can also be used in some occasions needing to be inserted into gaps for prying.

Referring to fig. 1, 2 and 4, the front and back of the fork tine 2 are provided with skidproof patterns 21, wherein the front and back of the fork tine 21 are the side surfaces perpendicular to the plane of the U-shaped groove 5. As mentioned above, when the door handle 11 is pried by using the breaking-in head, the middle part of the front surface or the back surface of the fork tooth 21 is abutted and contacted with the door handle 11, and at the moment, the anti-slip pattern 21 can increase the friction force between the fork tooth 2 and the door handle 11, prevent slipping during prying and improve efficiency.

Furthermore, the grain direction of the anti-skid patterns 21 is vertical to the extending direction of the prying rod 3, the direction of the anti-skid patterns 21 is just consistent with the direction of the door handle 11, the door handle 11 can be clamped in the grains, the resistance is increased, and the relative displacement with the door handle 11 during prying is reduced. Specifically, the anti-slip pattern 21 is a plurality of small grooves formed in the fork tines in parallel.

As shown in fig. 3, the broken lock handle 4 includes a main body 43, a screwdriver rod 42 and a lock cylinder sleeve 41, the screwdriver rod 42 is a polygonal limiting column with a cross section, the lock cylinder sleeve 41 is arranged at one end of the main body 43, the lock cylinder sleeve 41 is arranged at the other end of the main body 43, the lock cylinder is broken, the lock cylinder sleeve 41 is in an open sleeve shape, a notch 411 is arranged at one side of the opening, the notch 411 extends along the axis of the sleeve, the cross section of the lock cylinder 7 includes a circular portion and an extension portion, the lock cylinder sleeve 41 is sleeved on the circular portion, the extension portion just extends out of the notch, and the lock cylinder sleeve and the lock cylinder are just in fit and clamped.

With reference to fig. 3, in the aspect of the detachable connection structure between the lock breaking handle 4 and the pry bar 3, the other end of the pry bar 3 is in the shape of an open hollow rod, and the screwdriver rod 42 of the lock breaking handle is inserted into the hollow cavity 32 of the pry bar 3 from the open end along the axial direction of the pry bar 3 and is connected with the pry bar 3 through a thread. After the screwdriver rod 42 is completely immersed into the pry bar hollow cavity 32, the outer wall of the broken lock handle main body 43 and the open inner wall of the pry bar 3 are connected together in a matching mode through connecting threads, and detachable connection is achieved.

In the present embodiment, the screwdriver head 42 is a flat screwdriver, and in other embodiments, the screwdriver head 42 may also be a cross head, all within the scope of the present invention.

It is worth mentioning, combine shown in fig. 3, 4, screwdriver rod 42 cross-section is the polygon, the position that crow bar 3 is close to broken head of tearing is equipped with the polygon hole 31 with screwdriver rod 42 cross sectional shape adaptation, break lock handle 4 suit back on lock core 7, crow bar 3 matches through polygon hole 31 and screwdriver rod 42, at this moment, crow bar 3 and broken lock handle 4 are mutually perpendicular, hold the tip that the crow bar kept away from broken lock handle, the arm of force is elongated, apply the revolving force, alright easily twist off the lock core, realize breaking open.

In this embodiment, screwdriver pole 42 cross-section is the hexagon, and in other embodiments, screwdriver pole 42's cross-section also can be other polygons, is also in the utility model discloses in the protection scope.

When the door handle is broken, the door handle is firstly broken through the breaking head and the prying bar 3, the lock cylinder cover plate 12 is damaged to a certain extent after the door handle 11 is broken, the lock cylinder cover plate is further broken by utilizing the screw cutter bar or the fork teeth, the internal lock cylinder is exposed, the lock cylinder is sleeved by utilizing the lock cylinder sleeve of the broken lock handle after the lock cylinder is exposed, the prying bar is matched to prolong the force arm, the lock cylinder is twisted off, and finally the door lock is broken.

Example 2:

as shown in fig. 7 to 9, in the case of the same other features as those of embodiment 1, in this embodiment, the breaking head is shaped like a hatchet, a side opposite to the pry bar 3 is provided with a second U-shaped groove 51, and the bottom and the wall of the second U-shaped groove 52 are provided with saw teeth to increase the friction force with the door handle 11.

In addition, the breaking-in head is also provided with a jaw 62 and a blade 61, and the jaw 62 and the blade 61 are respectively arranged on two adjacent sides of the side where the pry bar 3 is located. Wherein, the side of the jaw 62 is narrowed gradually, the upper and lower part of the jaw 62 forms the point, and the jaw 62 is provided with the sawtooth. The edge 61 can cut and smash the door panel 1 to accelerate the door breaking process.

The axe-shaped breaking head 6 is provided with a polygonal hole 63 matched with the cross section of the screwdriver rod in shape, and after the lock core sleeve of the broken lock handle is matched with the lock core, the screwdriver rod 42 of the broken lock handle is matched with the polygonal hole 63, so that the rotating force arm is further prolonged, and the speed of breaking and dismantling the lock core is improved.
