Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 2-5, the unlocking tool of the four-dimensional diamond lock disclosed by the embodiment of the utility model comprises a key 1 and foam sponge or tinfoil 2. When the foam sponge is specifically used, the foam sponge can be foam sponge or tinfoil, and the foam sponge is taken as an example for description.

Specifically, the key 1 has a key handle 12 and a key lever 11, the key lever 11 is connected with the key handle 12, the key lever 11 has a plate body 111 suitable for being inserted into a lock hole of a lock cylinder, the plate body 111 has a first surface and a second surface which are wider, a first raised line 112 and a second raised line 113 extending along the length direction of the plate body 111 are arranged on the first surface, the first raised line 112 and the second raised line 113 are arranged at intervals along the width direction of the plate body 111 to jointly construct a first straight groove 114, the first raised line 112 passes through the side edge of the first cambered surface 115 and joins the plate body 111, the second raised line 113 and the side edge of the plate body 111 jointly construct a second straight groove 116 with an open side surface, and the inserting end of the second raised line 113 is provided with a chamfer 117 so that the width of an inserting port of the second straight groove 116 is gradually reduced; it can be understood that, compared to the conventional key, the plate 111 has the holes and the blade grooves with different depths for the single row of pins and the single row of blades, which are arranged and combined to form different keys corresponding to different locks, the depths of the first straight groove 114 and the second straight groove 116 of the key 1 in this embodiment are the same, and the arrangement and combination are not required.

The foam sponge 2 is adapted to be inserted into the first straight groove 114 and the second straight groove 116 such that when the plate 111 is inserted into the lock hole and the key handle 12 is shaken, the first straight groove 114 drives the foam sponge 2 to push the pins of the lock cylinder to the unlocking position, and the second straight groove 116 drives the foam sponge to push the blades of the lock cylinder to the unlocking position. It can be appreciated that the foam sponge 2 is relatively bulky, when the key rod 11 is inserted into the lock hole, the foam sponge 2 is located between the key rod 11 and the inner wall of the lock hole, and due to the material of the foam sponge, even the first straight groove 114 or the second straight groove 116 with the same depth, when the foam sponge is shaken, the spring or the spark of the blade at different positions can be copied by utilizing elasticity, and the lock core is forcefully opened after being copied to a certain degree, so that the lock core is unlocked. Wherein, a strip-shaped foam sponge 2 is embedded in each of the first straight groove 114 and the second straight groove 116. The length of the foam sponge 2 is more than or equal to the length of the straight groove.

Therefore, according to the unlocking tool for the four-dimensional diamond lock, when the four-dimensional diamond lock on the door is broken and disassembled, the first straight groove 114 and the second straight groove 116 are both internally provided with the strip-shaped foam sponge 2, the foam sponge 2 can be glued and inserted into the lock hole of the lock cylinder, at the moment, the foam sponge or the tinfoil embedded into the first straight groove 114 can jack all the pins to the highest position, then all the lower pins enter the upper pin bin, at the moment, the tolerance amount can appear, the key handle is operated to enable the key rod to shake, after the space of the upper pin dragged to the highest position shakes, the lower pins continuously move, move into the inner core, the lower pins are out of balance, the lower pins are supported by the foam sponge, and all the pins of the lock cylinder can be jacked to the unlocking position, the foam sponge of the second straight groove 116 can perform the same operation on a single row of blades, so that the lock is unlocked, the lock is further broken and disassembled, and the time is shortened, and the noise generated is small.

Wherein, the side surface of the second straight groove 116 is open for adapting to the shape of the blade in the lock hole; the insertion end of the second straight slot 116 is provided with a chamfer 117, which facilitates guiding the second straight slot 116 to the unlocking use of the corresponding blade.

In some examples, the second surface is a second arcuate surface 118, one side of the second arcuate surface 118 engages the first arcuate surface 115, and the other end of the second arcuate surface 118 engages a side of the plate body 111. Thus, the plate body 111 can be matched with the shape in the lock hole on the lock cylinder.

For the spoon handle 12, the spoon handle 12 is provided with a first handle body 121, a second handle body 122 and a third handle body 123, one end of the first handle body 121 is connected with the spoon rod 11, the other end is connected with the second handle body 122, the second handle body 122 is connected with the third handle body 123, the first handle body 121, the second handle body 122 and the third handle body 123 are all cylinders, and the diameter of the first handle body 121 is smaller than that of the second handle body 122 and smaller than that of the third handle body 123. Thus, by using the tapered handle body as the spoon handle 12, the weight of the spoon handle 12 can be reduced, and the spoon handle 12 has enough supporting force.

Further, the second handle 122 and the third handle 123 are engaged by the vertebral body 124. Thus, by the connection of the vertebral bodies 124, sufficient support is provided between adjacent handle bodies.

Specifically, the key lever 11 is welded to the first handle body 121, and the first handle body 121, the second handle body 122, the cone 124, and the third handle body 123 are integrally formed.

In addition, the third handle 123 is provided with a through channel 1231, and the channel 1231 is adapted to be inserted into the operating rod 13 for holding. When the operating rod 13 is inserted into the third handle 123, the handle 12 can be held to shake the key rod 11. When the operating rod 13 is inserted into the third handle 123, the operating rod 13 and the spoon handle 12 form a T-shaped structure.

When the portable lock is required to be carried, the operating rod 13 is separated from the key handle 12, so that the lock unlocking tool is convenient to be put into a bag or a box for carrying. When the lock is to be broken, the operation lever 13 is inserted into the passage 1231.

Wherein, the channel 1231 is provided with a protrusion 1232 adapted to abut against the lever 13, and the protrusion 1232 has a certain friction force on the lever 13, so that the lever 13 will not slip in the channel 1231 or separate from the spoon handle 12.
