[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0042] The following combination Figures 1 to 7 , describing the embodiments of the present application.

[0043] According to an embodiment of the present application, on the one hand, a key is provided, such as Figure 1 、 Figure 2 and Figure 6 As shown, it comprises: a first key segment 1, a key blank 2 and a first locking structure 3. The key blank 2 can be made into a corresponding key unlocking structure according to actual needs.

[0044] A first chute 8 is defined in the first key segment 1, with an opening at one end. A key blank 2 is slidably inserted into the first chute 8. The key blank 2 can slide along the first chute 8 relative to the first key segment 1 between a first position and a second position. When the key blank 2 slides from the first position to the second position, it extends out of the first chute 8 through the opening. When the key blank 2 slides from the second position to the first position, it extends into the first chute 8 through the opening.

[0045] The first locking structure 3 is provided on the key blank 2. When the key blank 2 is in the first position, the key blank 2 can be connected to the first key segment 1 through the first locking structure 3, thereby limiting the sliding of the key blank 2. When the key blank 2 is in the second position, the key blank 2 can be connected to the first key segment 1 through the first locking structure 3, thereby limiting the sliding of the key blank 2.

[0046] With this arrangement, when the key is used, the key blank 2 is pushed to slide along the first slide groove 8, causing the key blank 2 to slide from the first position to the second position. At this time, the key blank 2 extends out of the first slide groove 8, so that the entire length of the key is extended to the use length. The use length is the length required to unlock the key using the key.

[0047] At the same time, after the key blank 2 slides to the second position, it is connected to the first key segment 1 through the first locking structure 3, thereby restricting the key blank 2 from sliding toward the first position, thereby ensuring normal use of the key.

[0048] After use, the first locking structure 3 is disconnected from the first key segment 1, and the key blank 2 is then pushed to slide along the first slide groove 8, causing the key blank 2 to slide from the second position to the first position. At this time, the key blank 2 extends into the first slide groove 8, shortening the overall length of the key. Furthermore, after the key blank 2 slides to the first position, the first locking structure 3 is connected to the first key segment 1, thereby restricting the key blank 2 from sliding toward the second position and preventing the key from sliding out of the first slide groove 8, making storage and carrying more convenient.

[0049] As an optional embodiment, Figure 3 As shown, the first locking structure 3 includes a first elastic member 31 and a first engaging ball 32. The first elastic member 31 may be a spring. The first end of the first elastic member 31 is connected to the key blank 2, and the second end of the second elastic member 51 is connected to the first engaging ball 32. A first engaging hole 9 and a second engaging hole 10 are provided on the inner wall of the first chute 8. The first engaging hole 9 and the second engaging hole 10 are arranged sequentially along the sliding direction of the key blank 2.

[0050] When the key blank 2 is in the first position, the first engaging ball 32 is inserted into the first engaging hole 9 under the elastic force of the first elastic member 31, thereby restricting the key blank 2 from sliding along the first chute 8 to the second position. When the key is needed, the key blank 2 is pushed toward the second position. At this point, the first engaging ball 32 overcomes the elastic force of the first elastic member 31 and leaves the first engaging hole 9. As the key blank 2 slides, the first engaging ball, under the elastic force of the first elastic member 31, abuts against the inner wall of the first chute 8. When the key blank 2 slides to the second position, the first engaging ball 32 is inserted into the second engaging hole 10 under the elastic force of the first elastic member 31, restricting the key blank 2 from sliding along the first chute 8 to the first position.

[0051] After use, the key blank 2 is pushed firmly toward the first position. The first engaging ball 32 overcomes the elasticity of the first elastic member 31 and leaves the second engaging hole 10. As the key blank 2 slides, the first engaging ball 32, under the elastic force of the first elastic member 31, rests against the inner wall of the first chute 8. When the key blank 2 reaches the first position, the elastic force of the first elastic member 31 forces the first engaging ball 32 into the first engaging hole 9, restricting the key blank 2 from sliding along the first chute 8 toward the first position.

[0052] In an optional embodiment, if Figure 7 As shown, the key blank 2 includes a key blank body 21 and a sliding block 22. The key blank body 21 is connected to the sliding block 22 and moves synchronously. The sliding block 22 is slidably disposed in the first slide groove 8. The key blank body 21 can be made into a corresponding key structure according to requirements.

[0053] A first mounting hole 11 is provided on the bottom outer wall of the sliding block 22, and a first elastic member 31 is disposed within the first mounting hole 11. The first end of the first elastic member 31 is connected to the inner bottom wall of the first mounting hole 11, and the second end of the first elastic member 31 is connected to a first engaging ball 32. Pressing the first engaging ball 32 overcomes the elasticity of the first elastic member 31 and allows it to enter the first mounting hole 11. A first engaging hole 9 and a second engaging hole 10 are provided on the bottom wall of the first chute 8.

[0054] When the key is to be used, the key blank 2 is pushed and slid from the first position to the second position. At this time, the first engaging ball 32 overcomes the elasticity of the first elastic member 31, leaves the first engaging hole 9, and enters the first mounting hole 11. After use, the key blank 2 is pushed and slid toward the first position. At this time, the first engaging ball 32 overcomes the elasticity of the first elastic member 31, leaves the second engaging hole 10, and enters the first mounting hole 11.

[0055] In this arrangement, since the first engaging ball 32 can enter the first mounting hole 11, the outer wall of the sliding block 22 can fit into the inner wall of the first chute 8. This makes the sliding block 22 more stable when sliding along the first chute 8 and makes the whole more compact.

[0056] In one embodiment, Figure 5 As shown, the key also includes a second key segment 4 and a second locking structure 5. A second slide groove 12 is provided on the second key segment 4, and an opening is provided at one end of the second slide groove 12. The first key segment 1 is slidably inserted into the second slide groove 12. At this time, the first key segment 1 can slide along the second slide groove 12 relative to the second key segment 4 between a third position and a fourth position. When the first key segment 1 slides from the third position to the fourth position, the first key segment 1 extends out of the second slide groove 12 from the opening of the second slide groove 12. When the first key segment 1 slides from the fourth position to the third position, the first key segment 1 extends into the second slide groove 12 from the opening of the second slide groove 12.

[0057] The second locking structure 5 is arranged on the first key segment 1. When the first key segment 1 is in the third position, the first key segment 1 can be connected to the second key segment 4 through the second locking structure 5, thereby limiting the sliding of the first key segment 1. When the first key segment 1 is in the fourth position, the first key segment 1 can be connected to the second key segment 4 through the second locking structure 5, thereby limiting the sliding of the first key segment 1.

[0058] With this arrangement, when using the key, the first key segment 1 is pushed to slide along the second chute 12, causing the first key segment 1 to slide from the third position to the fourth position, at which point the first key segment 1 extends out of the second chute 12. The key blank 2 is then pushed to slide along the first chute 8, causing the key blank 2 to extend out of the first chute 8. This allows the entire key to be lengthened to its usable length. This two-stage lengthening allows for a longer usable length.

[0059] At the same time, after the first key segment 1 slides to the fourth position, it is connected to the second key segment 4 through the second locking structure 5, thereby limiting the first key segment 1 from sliding to the third position, ensuring the normal use of the key.

[0060] After use, the second locking structure 5 is disconnected from the second key segment 4, and the first key segment 1 is pushed to slide along the second slide groove 12, so that the first key segment 1 slides from the fourth position to the third position, at which time the first key segment 1 extends into the second slide groove 12. The first locking structure 3 is then disconnected from the first key segment 1, and the key blank 2 is pushed to slide along the first slide groove 8, so that the key blank 2 extends into the first slide groove 8, thereby shortening the entire length of the key.

[0061] Moreover, after the first key segment 1 slides to the third position, it is connected to the second key segment 4 through the second locking structure 5, thereby limiting the first key segment 1 from sliding to the fourth position, preventing the key from sliding out of the second sliding groove 12, making it more convenient to store and carry.

[0062] As an optional embodiment, Figure 3 As shown, the second locking structure 5 includes a second elastic member 51 and a second engaging ball 52. The second elastic member 51 may be a spring. The first end of the second elastic member 51 is connected to the first key segment 1, and the second end of the second elastic member 51 is connected to the second engaging ball 52. A third engaging hole 13 and a fourth engaging hole 14 are provided on the inner wall of the second chute 12. The third engaging hole 13 and the fourth engaging hole 14 are arranged sequentially along the sliding direction of the first key segment 1.

[0063] When the first key segment 1 is in the third position, under the elastic force of the second elastic member 51, the second engaging ball 52 is inserted into the third engaging hole 13, thereby limiting the first key segment 1 from sliding along the second slide groove 12 to the fourth position. When the key is needed, the first key segment 1 is pushed to slide toward the fourth position. At this time, the second engaging ball 52 overcomes the elasticity of the second elastic member 51 and leaves the third engaging hole 13. As the first key segment 1 slides, the first engaging ball rests against the inner wall of the second slide groove 12 under the elastic force of the second elastic member 51. When the first key segment 1 slides to the fourth position, under the elastic force of the second elastic member 51, the second engaging ball 52 is inserted into the fourth engaging hole 14, limiting the first key segment 1 from sliding along the second slide groove 12 to the third position.

[0064] After use, the first key segment 1 is pushed firmly to slide toward the third position. At this point, the second engaging ball 52 overcomes the elasticity of the second elastic member 51 and leaves the fourth engaging hole 14. As the first key segment 1 slides, the second engaging ball 52, under the elastic force of the second elastic member 51, rests against the inner wall of the second chute 12. When the first key segment 1 slides to the third position, the second engaging ball 52, under the elastic force of the second elastic member 51, inserts into the third engaging hole 13, restricting the first key segment 1 from sliding along the second chute 12 toward the third position.

[0065] In an optional embodiment, a second mounting hole 15 is provided on the outer wall of the first key segment 1, and a second elastic member 51 is disposed within the second mounting hole 15. The first end of the second elastic member 51 is connected to the inner bottom wall of the second mounting hole 15, and the second end of the second elastic member 51 is connected to the second engaging ball 52. Pressing the second engaging ball 52 overcomes the elasticity of the second elastic member 51 and allows the second engaging ball 52 to enter the second mounting hole 15. The third engaging hole 13 and the fourth engaging hole 14 are disposed on the inner sidewall of the second chute 12.

[0066] When the key is to be used, the first key segment 1 is pushed firmly to slide from the third position to the fourth position. At this time, the second engaging ball 52 overcomes the elasticity of the second elastic member 51, leaves the third engaging hole 13, and enters the second mounting hole 15. After use, the first key segment 1 is pushed firmly to slide to the third position. At this time, the second engaging ball 52 overcomes the elasticity of the second elastic member 51, leaves the fourth engaging hole 14, and enters the second mounting hole 15.

[0067] In this arrangement, since the second engaging ball 52 can enter the second mounting hole 15, the outer wall of the first key segment 1 can fit into the inner wall of the second chute 12. This makes the first key segment 1 more stable when sliding along the second chute 12, and also makes the whole more compact.

[0068] In a further embodiment, Figure 4 As shown, the key further includes a third key segment 6 and a third locking structure 7. A third sliding groove 16 is provided on the third key segment 6, and an opening is provided at one end of the third sliding groove 16. The second key segment 4 is slidably inserted into the third sliding groove 16. At this time, the second key segment 4 can slide along the third sliding groove 16 relative to the third key segment 6 between a fifth position and a sixth position. When the second key segment 4 slides from the fifth position to the sixth position, the second key segment 4 extends out of the third sliding groove 16 from the opening of the third sliding groove 16. When the second key segment 4 slides from the sixth position to the fifth position, the second key segment 4 extends into the third sliding groove 16 from the opening of the third sliding groove 16.

[0069] The third locking structure 7 is arranged on the second key segment 4. When the second key segment 4 is in the fifth position, the second key segment 4 can be connected to the third key segment 6 through the third locking structure 7, thereby limiting the sliding of the second key segment 4. When the second key segment 4 is in the sixth position, the second key segment 4 can be connected to the third key segment 6 through the third locking structure 7, thereby limiting the sliding of the second key segment 4.

[0070] With this arrangement, when using the key, the second key segment 4 is pushed to slide along the third chute 16, causing it to slide from the fifth position to the sixth position, at which point it extends out of the third chute 16. The first key segment 1 is then pushed to slide from the third position to the fourth position, causing it to extend out of the second chute 12. The key blank 2 is then pushed to slide along the first chute 8, causing it to extend out of the first chute 8. This results in the overall length of the key being extended to its usable length. This three-stage lengthening mechanism allows for a longer usable length.

[0071] At the same time, after the second key segment 4 slides to the sixth position, it is connected to the third key segment 6 through the third locking structure 7, thereby limiting the second key segment 4 from sliding to the fifth position, ensuring the normal use of the key.

[0072] After use, the third locking structure 7 is disconnected from the third key segment 6, and the second key segment 4 is pushed to slide along the third slide groove 16, causing the second key segment 4 to slide from the sixth position to the fifth position, at which point the second key segment 4 extends into the third slide groove 16. The second locking structure 5 is then disconnected from the second key segment 4, and the first key segment 1 is pushed to slide along the second slide groove 12, causing the first key segment 1 to slide from the fourth position to the third position, at which point the first key segment 1 extends into the second slide groove 12. The first locking structure 3 is then disconnected from the second key segment 4, and the key blank 2 is pushed to slide along the first slide groove 8, causing the key blank 2 to extend into the first slide groove 8, thereby shortening the overall length of the key.

[0073] Moreover, after the second key segment 4 slides to the fifth position, it is connected to the third key segment 6 through the third locking structure 7, thereby limiting the second key segment 4 from sliding to the sixth position, preventing the key from sliding out of the third sliding groove 16, making it more convenient to store and carry.

[0074] As an optional embodiment, Figure 3 As shown, the third locking structure 7 includes a third elastic member 71 and a third engaging ball 72. The third elastic member 71 may be a spring. The first end of the third elastic member 71 is connected to the second key segment 4, and the second end of the third elastic member 71 is connected to the third engaging ball 72. A fifth engaging hole 17 and a sixth engaging hole 18 are provided on the inner wall of the third chute 16. The fifth engaging hole 17 and the sixth engaging hole 18 are arranged sequentially along the sliding direction of the second key segment 4.

[0075] When the second key segment 4 is in the fifth position, the third engaging ball 72 is inserted into the fifth engaging hole 17 under the elastic force of the third elastic member 71, thereby limiting the second key segment 4 from sliding along the third slide groove 16 to the sixth position. When the key is needed, the second key segment 4 is pushed to slide toward the sixth position. At this time, the third engaging ball 72 overcomes the elasticity of the third elastic member 71 and leaves the fifth engaging hole 17. As the second key segment 4 slides, the first engaging ball abuts against the inner wall of the third slide groove 16 under the elastic force of the third elastic member 71. When the second key segment 4 slides to the sixth position, the third engaging ball 72 is inserted into the sixth engaging hole 18 under the elastic force of the third elastic member 71, limiting the second key segment 4 from sliding along the third slide groove 16 to the fifth position.

[0076] After use, the second key segment 4 is pushed firmly to slide toward the fifth position. At this point, the third engaging ball 72 overcomes the elasticity of the third elastic member 71 and leaves the sixth engaging hole 18. As the second key segment 4 slides, the first engaging ball, under the elastic force of the third elastic member 71, abuts against the inner wall of the third chute 16. When the second key segment 4 slides to the fifth position, the third engaging ball 72, under the elastic force of the third elastic member 71, inserts into the fifth engaging hole 17, restricting the second key segment 4 from sliding along the third chute 16 toward the fifth position.

[0077] In an optional embodiment, a third mounting hole is provided on the outer wall of the second key segment 4, and a third elastic member 71 is positioned within the third mounting hole. The first end of the third elastic member 71 is connected to the inner bottom wall of the third mounting hole, and the second end of the third elastic member 71 is connected to a third engaging ball 72. Pressing the third engaging ball 72 overcomes the elasticity of the third elastic member 71 and allows the third engaging ball 72 to enter the third mounting hole. Fifth and sixth engaging holes 17, 18 are provided on the inner sidewall of the third chute 16.

[0078] When the key is needed, the second key segment 4 is pushed to slide from the fifth position to the sixth position. At this time, the third engaging ball 72 overcomes the elasticity of the third elastic member 71, leaves the fifth engaging hole 17, and enters the third mounting hole. After use, the second key segment 4 is pushed to slide to the fifth position. At this time, the third engaging ball 72 overcomes the elasticity of the third elastic member 71, leaves the sixth engaging hole 18, and enters the third mounting hole.

[0079] In this way, since the third engaging ball 72 can enter the third mounting hole, the outer wall of the second key segment 4 can fit into the inner wall of the third chute 16. This makes the second key segment 4 more stable when sliding along the third chute 16, and also makes the whole more compact.

[0080] It is worth noting that a fourth key segment, a fifth key segment or more key segments may be provided to enable the key to be unfolded and folded in more stages to obtain a longer usable length.
