Description

Technical Field

[0001] This utility model relates to the field of keys, and more particularly to a foldable key. Background Technology

[0002] A key is a tool used to open or lock doors, boxes, vehicles, and other devices. It is typically made of metal and has unique teeth or grooves that match the internal structure of the lock cylinder. By inserting and turning the key, the mechanical mechanism of the lock is activated, enabling the lock to be unlocked or locked. There are various types of keys, including traditional mechanical keys, electronic chip keys (such as car remote keys), and modern digital keys (such as passwords or fingerprint recognition). Their core function is to provide security control, ensuring that only authorized persons can access specific spaces or items. Combining portability and confidentiality, they are one of the important security tools in daily life.

[0003] The key can be retracted and folded. In some special scenarios, the key needs to have different ways of extending to ensure stable use.

[0004] While existing technologies can achieve certain key unlocking functions, they suffer from the following drawbacks: they lack multi-functional folding and unfolding capabilities, resulting in limited usage options and inability to guarantee stable key operation in certain special scenarios. Therefore, we propose a foldable key that solves the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a foldable key.

[0006] The technical solution of this utility model is as follows: A foldable key includes a mounting block, a moving block, and a rotating block. The mounting block has a guide rail inside, and a moving block is inserted into the guide rail. A rotating block is rotatably mounted in the middle of the moving block. A body is provided on one side of the rotating block. A second limiting block with an elastic element is provided inside the mounting block, and a first limiting block with an elastic element is provided on the inner wall of the guide rail.

[0007] This device offers two ways to retract and extend the key body. The first is linear retraction: the key body is pressed directly into the guide rail along the axis. After the moving block breaks through the locking of limit block one, it enters the bottom limit block one of the guide rail and locks. At this point, the key body is neatly retracted into the mounting block. To open, simply push the moving block to one end. The second method involves rotating the key body when the moving block is at the outermost edge of the guide rail. After rotating 90 degrees, the key body is fixed by limit block two. At this point, the key body is neatly retracted into the mounting block. To open, press down on limit block two, and the key body will rotate out. This device features a multi-functional key retraction and folding function, providing different usage options, maximizing its emotional value, and possessing high practicality.

[0008] Preferably, the rotating block has an installation groove on one side, the key body is inserted into the installation groove, the inner wall of the installation groove has a limiting block three on both sides, the bottom of the limiting block three is provided with a linear spring three between the bottom of the limiting block three and the inner wall of the installation groove, and the key body has a limiting groove on one side. The design of the installation groove and the limiting block three allows the key body to be quickly inserted and removed for replacement. The linear spring three provides buffering and fixing force, ensuring stable installation of the key while reducing wear and extending service life.

[0009] Preferably, a torsion spring is provided on one side of the movable block, and the torsion end of the torsion spring is fixedly connected to the rotation center on one side of the rotating block. The addition of the torsion spring enables the rotating block to have an automatic rebound function, eliminating the need for manual reset when folding the key, making the operation smoother and improving the user experience.

[0010] Preferably, a linear spring is provided between the bottom of the second limiting block and the interior of the mounting block. The second limiting block is designed at a right angle. The right-angled limiting block and the linear spring work together to accurately lock in place when the key is rotated 90°, providing a firm locking effect and preventing accidental activation.

[0011] Preferably, a linear spring is fixed between the bottom of the limiting block and the inside of the guide rail. The two sides of the limiting block are designed to be inclined. The inclined limiting block and the linear spring work together to achieve a smooth "press to unlock" feel when the moving block slides in a straight line, while ensuring stable positioning inside the guide rail.

[0012] Preferably, the mounting block has a through hole on one side, which facilitates hanging or carrying with a rope, increasing portability.

[0013] Preferably, a limiting plate is fixed on one side of the movable block. After the limiting plate contacts the main body, the main body is parallel to the mounting block. The parallel design of the limiting plate and the main body ensures that the key body and the mounting block fit completely after folding, resulting in a compact structure and preventing protruding parts from scratching clothing or items.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the insertion design of the guide rail and the moving block, combined with a double limiting structure (limiting block one and limiting block two), achieves two storage methods for the key body: linear retraction and rotary folding. Linear retraction facilitates quick and easy hiding of the key, saving space; rotary folding provides a more stable fixation effect, preventing accidental slippage. The two methods can be flexibly switched to meet the needs of different scenarios, significantly improving ease of use and security.

[0016] II. Based on the first beneficial effect, this device, through a multi-module collaborative design (guide rails, limiting blocks, springs, etc.), achieves both linear retraction and rotary folding of the key, balancing space saving and ease of operation. Optimized elastic elements and limiting structures enhance stability and durability, while replaceable key bodies, automatic rebound, and portable design further enhance practicality. The overall structure is compact and multifunctional, meeting daily storage needs while improving user experience through thoughtful details, making it highly practical.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a foldable key, including a mounting block 1, a moving block 6 and a rotating block 12. The mounting block 1 is provided with a guide rail 5 inside, and the moving block 6 is inserted into the guide rail 5. The rotating block 12 is rotatably mounted in the middle of the moving block 6. The rotating block 12 is provided with a body 9 on one side. The mounting block 1 is provided with a limiting block 2 3 with an elastic element inside, and the inner wall of the guide rail 5 is provided with a limiting block 2 with an elastic element.

[0030] This device offers two ways to retract and extend the key body 9 during use. The first method is linear retraction, where the key body 9 is directly pressed into the guide rail 5 along the axial direction. After the moving block 6 breaks through the locking of the first limiting block 2, it enters the locking block 2 at the bottom of the guide rail 5 and locks. At this point, the key body 9 is neatly retracted into the mounting block 1. To open, simply push the moving block 6 to one end. The second method involves rotating the key body 9 when the moving block 6 is at the outermost edge of the guide rail 5. After rotating 90 degrees, the key body 9 is fixed by the second limiting block 3. At this point, the key body 9 is neatly retracted into the mounting block 1. To open, press down on the second limiting block 3, and the key body 9 will rotate out. This device features a multi-functional key retraction and folding function, providing different usage options, maximizing its emotional value, and possessing high practicality.

[0031] Example 2

When folding the key, there is no need to manually reset it, making the operation smoother and improving the user experience.

[0034] A linear spring 15 is provided between the bottom of the limiting block 2 3 and the inside of the mounting block 1. The limiting block 2 3 is designed at a right angle. The right-angled limiting block 2 3 and the linear spring 15 cooperate to accurately lock in place when the key is rotated 90°, providing a firm locking effect and preventing accidental activation.

[0035] A linear spring 14 is fixed between the bottom of the limiting block 12 and the inside of the guide rail 5. The two sides of the limiting block 12 are inclined. The inclined limiting block 12 and the linear spring 14 work together to make the moving block 6 achieve a smooth "press to unlock" feel when sliding in a straight line, while ensuring stable positioning inside the guide rail 5.

[0036] The mounting block 1 has a through hole 4 on one side. The through hole 4 is designed to facilitate hanging or carrying with a rope, thus increasing portability.

[0037] A limiting plate 13 is fixed on one side of the movable block 6. After the limiting plate 13 contacts the body 9, the body 9 is parallel to the mounting block 1. The parallel design of the limiting plate 13 and the body 9 ensures that the key body 9 and the mounting block 1 fit completely after folding. The structure is compact and avoids the protruding parts from scratching clothes or items.
