[0033] The following combination Figures 1 to 4 , describing the door lock key, door lock and door of the embodiment of the present invention.

[0034] According to an embodiment of the present invention, on the one hand, a door lock key is provided, comprising a key handle 1, a key arm 2, and an adjustment mechanism. Specifically, Figure 2As shown, the key arm 2 is connected to the key handle 1. The key handle 1 is easy for the user to hold and operate. The key arm 2 includes teeth or grooves that match the lock cylinder and are used to open or lock the lock. An adjustment mechanism is provided between the key arm 2 and the key handle 1. The adjustment mechanism is used to adjust the distance between the first end 3 of the key handle 1 and the second end 4 of the key arm 2. It should be noted that, as shown in FIG. Figure 2 As for the placement position of the door lock key shown in the figure, the first end 3 of the key handle 1 is the end of the key handle 1 away from the key arm 2, and the second end 4 of the key arm 2 is the end of the key arm 2 away from the key handle 1.

[0035] With this arrangement, the distance between the first end 3 of the key handle 1 and the second end 4 of the key arm 2 can be adjusted via the adjustment mechanism. This allows the relative position of the key handle 1 to be adjusted according to the unlocking space within the keyhole, facilitating smooth insertion and unlocking of the key. The adjustment mechanism also allows the key's overall length to be varied to accommodate doors of varying thicknesses, enhancing its versatility and applicability. The simple structure, ease of operation, and low manufacturing cost make it easy to use, allowing each person to be equipped with a key, greatly satisfying the needs of a household.

[0036] In some embodiments of the present invention, Figure 2 As shown, the adjustment mechanism includes a matching adjustment hole 5 and a connecting member 6. The connecting member 6 runs through the adjustment hole 5. The connecting member 6 can be a rivet, a pin, etc. The adjustment hole 5 is set through the key handle 1 and the key arm 2, and at least one of the key handle 1 and the key arm 2 is provided with at least two adjustment holes 5. Each adjustment hole 5 is spaced apart along the length direction of the door lock key. It should be noted that, as shown in FIG. Figure 2 For the placement of the door lock key shown in the figure, the left and right directions in the figure are the length directions of the door lock key, that is, Figure 2 The direction indicated by the arrow.

[0037] That is, in one embodiment, the key handle 1 is provided with an adjustment hole 5 therethrough, and the key arm 2 is provided with at least two adjustment holes 5 therethrough, and the adjustment holes 5 are spaced apart along the length direction of the door lock key.

[0038] In another embodiment, the key arm 2 is provided with an adjustment hole 5 therethrough, and the key handle 1 is provided with at least two adjustment holes 5 therethrough, and the adjustment holes 5 are spaced apart along the length direction of the door lock key.

[0039] In another embodiment, the key handle 1 is provided with at least two adjustment holes 5 therethrough, and the key arm 2 is provided with at least two adjustment holes 5 therethrough, and the adjustment holes 5 are spaced apart along the length direction of the door lock key.

[0040] With this arrangement, the key handle 1 and key arm 2 are aligned with each other by aligning the different adjustment holes 5. The connector 6 then passes through the aligned adjustment holes 5 to lock the key handle 1 and key arm 2. This allows the relative position of the key handle 1 and key arm 2 to be adjusted as needed, ensuring that the relative position of the key handle 1 and key arm 2 remains stable when required. It is understood that parameters such as the specifications and position of the adjustment holes 5 need to be determined based on actual design requirements. Furthermore, a first stop boss 601 can be provided at the end of the connector 6 to prevent accidental detachment of the connector 6, thereby ensuring a more reliable connection.

[0041] Of course, in other embodiments, the adjustment mechanism includes but is not limited to a combination of an adjustment hole 5 and a connector 6, and may also adopt a snap-fit ​​combination structure, etc., and make adaptive adjustments to achieve a change in the relative position between the key handle 1 and the key arm 2 by selecting different snap-fit ​​positions.

[0042] In some embodiments of the present invention, the key arm 2 is foldably connected to the key handle 1, and the key arm 2 and the key handle 1 can be switched between a folded state and an unfolded state. This arrangement allows the key to be switched from a compact folded state to an unfolded, usable state. When not in use, see Figure 3 and Figure 4 As shown, the key can be folded up to reduce the volume and be compactly stored, easy to put into a pocket or key bag for easy carrying. When you need to use the key, see Figure 1 and Figure 2 As shown, you only need to simply unfold it to the correct usage shape so that it can be inserted into the keyhole for operation.

[0043] In some embodiments of the present invention, the key arm 2 and the key handle 1 are rotatably connected via a connecting shaft 7, and the key arm 2 and the key handle 1 can be rotatably switched between a folded state and an unfolded state. Figure 1 As shown, to achieve a more compact structure, a connecting shaft 7 and a connecting member 6 are used at the connection point between the key arm 2 and the key handle 1. This allows for both adjusting the relative position of the key arm 2 and the key handle 1 and enabling a rotational connection between the key arm 2 and the key handle 1. Thus, by rotating the key arm 2 or the key handle 1, the key arm 2 and the key handle 1 can be switched between a folded and unfolded state, providing both practicality and convenience, satisfying the user's dual needs for portability and functionality. Furthermore, a second stop boss 701 can be provided at the end of the connecting shaft 7 to prevent accidental detachment, further ensuring a more stable and reliable connection.

[0044] In some embodiments of the present invention, the number of key arms 2 is at least two, and two adjacent key arms 2 are rotatably connected by a connecting shaft 7. The number of key arms 2 needs to be determined according to actual design requirements to meet the use and storage needs in different scenarios. Take two key arms 2 as an example, specifically including a primary key arm 201 and a secondary key arm 202. Figure 1 As shown, at the connection point between the primary key arm 201 and the key handle 1, the connecting member 6 serves as the connecting shaft 7, enabling the rotational connection between the primary key arm 201 and the key handle 1. At the connection point between the secondary key arm 202 and the primary key arm 201, mounting holes corresponding to the connecting member 6 are provided on the secondary key arm 202 and the primary key arm 201, respectively. The connecting member 6 passes through the two aligned mounting holes to achieve the rotational connection between the secondary key arm 202 and the primary key arm 201. This arrangement allows adjacent key arms 2 to be rotationally connected via the connecting shaft 7. This connection method allows for a certain degree of rotational flexibility in the construction of the key arms 2, facilitating the free switching between a folded and unfolded state. It features a simple structure and convenient operation.

[0045] In some embodiments of the present invention, Figure 3 As shown, in the folded state, the key handle 1 and each key arm 2 are stacked in sequence along the thickness direction of the door lock key. In this way, when not in use, the key sections can be folded and stored together, making the overall storage structure compact, small in size, and easy to carry. When needed, they can be unfolded in sequence to the use form. It should be noted that Figure 3 For the placement of the door lock key shown in the figure, the up and down direction is the thickness direction of the door lock key, that is, Figure 3 The direction indicated by the arrow.

[0046] In some embodiments of the present invention, Figure 2 As shown, the key handle 1 includes a handle portion 101 and a connecting portion 102 connected to each other. Specifically, the handle portion 101 and the connecting portion 102 can be formed in one piece. The connecting portion 102 is connected to the key arm 2, and an adjustment mechanism is provided between the connecting portion 102 and the key arm 2. In this manner, the handle portion 101 serves as the gripping portion of the key handle 1, making it convenient for the user's hand to comfortably grip and operate the key. The shape, size, and material of the handle portion 101 may vary depending on the type of key, its purpose, and the user's hand feel preference. The connecting portion 102 serves as the connecting portion between the handle portion 101 and the key arm 2, ensuring that the key arm 2 can be securely connected to the handle portion 101 while allowing the key arm 2 to rotate flexibly when inserted into the keyhole.

[0047] In some embodiments of the present invention, the handle portion 101 is provided with a hanging hole 8. This arrangement allows the user to easily hang keys on a key ring, key chain, or other carrying tool through the hanging hole 8, so that the user can conveniently carry multiple keys without worrying about the keys being lost or scattered, and makes the storage of keys more orderly and convenient, providing multiple conveniences for the user and meeting the needs of different scenarios.

[0048] In addition, the materials of the key handle 1 and the key arm 2 include but are not limited to powder metallurgy, sheet metal, PC (polycarbonate), PA66 (nylon-66, Polyadiohexylenediamine), etc., which fully meet the needs of different price ranges.

[0049] According to an embodiment of the present invention, another aspect is provided, including a door lock key as described in the various embodiments described above. With this arrangement, the distance between the first end 3 of the key handle 1 and the second end 4 of the key arm 2 can be adjusted via an adjustment mechanism, thereby adjusting the relative position of the key handle 1 according to the unlocking space at the keyhole, allowing the key to be smoothly inserted into the keyhole for unlocking. The adjustment mechanism can also change the total length of the key to accommodate different door thicknesses, providing greater versatility and applicability. The structure is simple, easy to operate, has low processing costs, and is convenient to use. Each person can be equipped with a key, significantly meeting the needs of the user's family. The derivation process for this beneficial effect is roughly similar to the derivation process for the beneficial effect of the door lock key described above, and will not be repeated here.

[0050] According to an embodiment of the present invention, on another aspect, a door is provided, comprising a door lock as described in the above embodiment. With this arrangement, the distance between the first end 3 of the key handle 1 and the second end 4 of the key arm 2 can be adjusted by an adjustment mechanism, thereby adjusting the relative position of the key handle 1 according to the unlocking space at the keyhole, so that the key can be smoothly inserted into the keyhole for unlocking. At the same time, the total length of the key can also be changed by the adjustment mechanism to adapt to the use requirements of doors of different thicknesses, thereby enhancing versatility and applicability. It has a simple structure, is easy to operate, has low processing costs, is convenient to use, and can be equipped with a key per person, greatly meeting the needs of the user's family. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned door lock, so it will not be repeated here.
