While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 2 to 6, an embodiment of the present utility model provides an unlocking tool of an AB positive slot lock, which includes an insertion portion 100 and a rotation portion 200 connected to each other.
Specifically, the insertion portion 100 has a flat plate shape suitable for insertion into a lock hole. A first slot 110 is formed in the front side of the insertion portion 100, and the first slot 110 is disposed along the longitudinal direction of the insertion portion 100. The length of the first slot 110 may extend from one end of the insertion portion 100 to the other end. In one example, the width of the first slot 110 may be half the width of the front face of the insertion portion 100. The depth of the first socket 110 near the end of the rotating part 200 may be gradually reduced in a direction near the rotating part 200 to secure the coupling strength with the rotating part 200.
The bottom surface of the first slot 110 is recessed downward to form a straight groove 111, the straight groove 111 extends along the length direction of the insertion portion 100, and the depth of the straight groove 111 gradually increases from two ends to the middle, so that the structure in the lock hole can be avoided. A second slot 120 is formed on the rear surface side of the insertion portion 100, and the second slot 120 is located diagonally to the first slot 110. The second slot 120 is disposed along the length direction of the insertion portion 100, and the bottom surface of the second slot 120 is provided with a division bar 121 along the length direction thereof, and the division bar 121 may extend from one end to the other end of the second slot 120. The height of the division bar 121 may be equal to the depth of the second slot 120, so as to divide the second slot 120 into channels through which ribs in the lock hole can pass.
The rotating portion 200 may have a rod shape to facilitate gripping. Therefore, through the arrangement of the first slot 110, the straight slot 111, the second slot 120 and the parting bead 121, the lock hole of the AB positive slot lock can be matched with the lock hole of the AB positive slot lock so as to facilitate insertion. In the actual use process, when the AB positive slot lock is broken and detached, an elastic material (such as tinfoil, foam sponge, etc.) can be placed into the slot, then the insertion portion 100 is inserted into the lock hole of the AB positive slot lock, and the rotation portion 200 is operated to rotate or shake the insertion portion 100, and the repeated operation is performed to make the marble in the lock hole move radially to the unlocking position to realize unlocking. Therefore, the efficiency of breaking and disassembling the AB positive slot lock can be improved, and the generated noise is small.
In one embodiment, the front surface of the insertion portion 100 has a sloped guiding surface at the end far from the rotation portion 200, so that the thickness of the end of the insertion portion 100 can be reduced, and the smaller thickness can facilitate the radial movement of the pins a certain distance during the insertion of the pins into the locking holes, so that the subsequent parts can be inserted smoothly.
In an embodiment, the rotating portion 200 includes a first rod portion 210, a second rod portion 220 and a third rod portion 230 sequentially connected, wherein one end of the first rod portion 210 is connected to the insertion portion 100, the other end is connected to the second rod portion 220, and the second rod portion 220 is connected to the third rod portion 230. And, the diameter of the first shaft portion 210 is smaller than the diameter of the second shaft portion 220, and the diameter of the second shaft portion 220 is smaller than the diameter of the third shaft portion 230. Alternatively, the first, second and third stem portions 210, 220, 230 may be integrally formed structures. Thus, by the arrangement of the first, second and third lever portions 210, 220 and 230 and the arrangement of the different diameters, the structural strength of the rotation portion 200 can be ensured while also being easy to hold.
In an embodiment, the unlocking tool further includes a holding rod 300, and a first insertion hole 231 into which the holding rod 300 is inserted is formed in a radial direction of an end of the third rod portion 230, which is far from the second rod portion 220. In actual use, the user can insert the grip lever 300 into the first insertion hole 231 to have a T shape so as to exert a force when breaking the door lock.
Further, the inner wall of the first insertion hole 231 is provided with a protrusion so that when the grip lever 300 is inserted into the first insertion hole 231, the side wall of the grip lever 300 may be abutted to increase friction with the grip lever 300. The grip lever 300 can be prevented from slipping in the first insertion hole 231 or from being separated from the third lever portion 230. In one example, the protrusion may be hemispherical.
In an embodiment, the third rod portion 230 is provided with a second jack 232 along an axial direction thereof, the second jack 232 is identical to the first jack 231, the second jack 232 may be square, and the second jack 232 may be used for inserting and clamping other auxiliary tools to improve an application range of the unlocking tool.
