Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and in particular to a keychain. Background Technology

[0002] For easy carrying, small everyday items such as keys, USB drives, and access cards are usually stored using key rings. While traditional key rings can hold these items together, they are inconvenient for frequent access. Most key rings on the market are traditional metal key rings, made by winding a metal wire two or more times. They use the elasticity of the metal and the spiral structure to lock onto the keyhole, and then use a latch to secure clothing or other items for hanging. However, this method is inconvenient for accessing keys. Users need to first unfasten the latch from the clothing and then rotate the key rings to remove it. This process can easily damage fingernails and is also cumbersome, time-consuming, and involves many steps. Utility Model Content

[0003] The main purpose of this utility model is to propose a keychain that aims to solve the problems of existing keychains being inconvenient to connect with other items and keys being difficult to retrieve.

[0004] To achieve the above objectives, this utility model proposes a keychain, comprising a first sidewall, a second sidewall, a connecting rod, and a hand-tightening screw, wherein one end of the first sidewall and the second sidewall are connected to each other; The connecting rod and the hand-tightening screw are respectively located at the other end of the first side wall and the second side wall, and the connecting rod and the hand-tightening screw are detachably connected to the other end of the first side wall and the second side wall; After the hand screw is turned until it separates from the connecting rod, external objects can be inserted between the first side wall and the second side wall and suspended on the connecting rod; The first sidewall or the second sidewall is also provided with a back clip, which is used to clamp other objects, so that the first sidewall or the second sidewall is connected to the external object.

[0005] Optionally, the back clip includes a spring and a base. The base is disposed on the outer surface of the first sidewall away from the second sidewall. One end of the spring is connected to the base by a fixing screw, and the other end has a first distance from the outer surface of the first sidewall, for forming a clamping structure.

[0006] Optionally, the spring sheet bends and extends along the extension direction of the first sidewall, causing the first distance to increase, then decrease, and then increase again.

[0007] Optionally, the first sidewall is provided with a box, and the box is located between the first sidewall and the second sidewall. One end of the connecting rod is located inside the box, and the other end extends out of the box and can be detachably connected with the hand-tightening screw.

[0008] Optionally, the box body includes a plastic top cover and a metal bottom shell. The plastic top cover is disposed on the inner surface of the first side wall facing the second side wall, and the metal bottom shell is connected to the plastic top cover and surrounds it to form a receiving cavity.

[0009] Optionally, the metal base shell is provided with a mounting groove, which communicates with the receiving cavity. The metal base shell is also provided with a first through hole. The connecting rod is positioned in the receiving cavity through the mounting groove and installed on the metal base shell through the first through hole.

[0010] Optionally, the connecting rod includes a nut and an external threaded rod, the nut and the external threaded rod are connected to each other, the nut abuts against the outer periphery of the first through hole in the mounting groove, and the external threaded rod extends out of the receiving cavity through the first through hole and moves axially to be detachably connected with the hand-tightening screw.

[0011] Optionally, the second sidewall is provided with a second through hole, and the hand-tightening screw has a disc. The disc abuts against a side of the second sidewall facing away from the first sidewall and is disposed corresponding to the second through hole. The rotating part of the hand-tightening screw is rotatably disposed on the side of the disc away from the second sidewall and connected to the disc for the user to rotate. The inner thread of the hand-tightening screw is connected to the disc and passes through the second through hole, extending toward the first sidewall, for forming an opening and closing structure with the outer thread.

[0012] Optionally, the keychain also includes a buzzer assembly and a battery cell, both of which are housed within the housing. A button is provided on one side wall of the housing to control the buzzer in the buzzer assembly, and a charging port is provided on the other side wall of the housing for electrical connection with the battery cell to charge it.

[0013] Optionally, the keychain includes a connecting part, the two ends of which are respectively connected to the first sidewall and the second sidewall, forming a structure in which one end of the first sidewall and the second sidewall are connected to each other, and the other end is opened and closed through the connecting rod and the hand-tightening screw.

[0014] Optionally, the key buckle has a protrusion for threading a lanyard, and the protrusion is located in the connecting part.

[0015] Optionally, the second sidewall is made of leather.

[0016] This utility model's technical solution uses the gap between the first and second sidewalls for connecting the connecting rod and the hand-tightening screw. One end of the first and second sidewalls is separated, while the other end is connected to each other. The connecting rod and the hand-tightening screw are respectively set on the first and second sidewalls, and the hand-tightening screw can rotate. When the hand-tightening screw is rotated to the point that the connecting rod and the hand-tightening screw are separated between the first and second sidewalls, the second sidewall can be controlled to move away from the first sidewall, allowing external objects such as keys to enter the connecting rod, forming a structure for the connecting rod to hang keys and other objects. This avoids the need for pressing the latch and other steps required by traditional hook and latch structures, making it simple and convenient for users to access. A back clip is provided on the first or second side wall, which can be clipped onto clothing, belts, or bags, so that pendants such as keys can be attached to clothing, belts, or bags. At the same time, the back clip can be clamped onto clothing, belts, or bags without pressing or opening and closing, making it easy to remove or install. Attached Figure Description

[0023] Small everyday items such as keys and USB drives are easily lost during transport, so using keychains to store, manage, and carry them is a common practice for consumers. While traditional keychains can hold these items together, they don't always fit well when frequently using a single key or when temporarily securing the entire keychain to a backpack, belt, or pocket, and they are not convenient for accessing these small items.

[0024] Currently, the market typically uses metal snap rings or spring hooks. However, while traditional metal snap rings offer high reliability, they are difficult to remove once attached, requiring the use of fingernails or tools to pry open the gap to insert or remove the key. Long-term use can damage fingernails and the snap ring structure, and can easily scratch other items. On the other hand, the spring in a spring hook can easily lose its elasticity, rendering it ineffective and posing a risk of losing the key.

[0025] To address the above problems, this utility model proposes a keychain 100, with reference to... Figure 1The gap between the first sidewall 10 and the second sidewall 20 is used for the connection rod 30 and the hand screw 40 to be separated and connected. The hand screw 40 can be rotated. When it is necessary to hang something on the connection rod 30, the hand screw 40 can be rotated so that the connection rod 30 and the hand screw 40 are separated between the first sidewall 10 and the second sidewall 20. At this time, the second sidewall 20 can be opened relative to the first sidewall 10. External items such as keys, USB flash drives, and pendants can enter the connection rod 30, forming a structure for the connection rod 30 to hang keys, USB flash drives, pendants, and other items. This avoids the need to press the latch and other steps required by traditional hook and lock structures, making it simple, convenient for users to access, and will not cause damage to fingernails or items. Furthermore, the back clip 60 provided on the first side wall 10 or the second side wall 20 can be clipped onto clothing, belts, or bags, allowing keychains and other pendants to be attached to clothing, belts, or bags. The back clip 60 can be adapted to attach various items, forming a clamp for objects without hooks or lanyards, making it more widely used. At the same time, the back clip 60 can be clamped and fixed onto clothing, belts, or bags without pressing or opening / closing structures, making it easy to remove or install.

[0026] During use, the user can turn the hand screw 40 until it separates from the connecting rod 30 or remove it from the second side wall 20 (e.g., Figure 7 Then, the external items are suspended onto the connecting rod 30. Due to the elasticity of the first sidewall 10 or the second sidewall 20, the first sidewall 10 can be moved away from the second sidewall 20, increasing the distance between the first sidewall 10 and the second sidewall 20 to allow multiple external items to be hung simultaneously. After hanging, the first sidewall 10 and the second sidewall 20 are brought closer together, and the hand-tightened screw 40 is placed back onto the second sidewall 20. The hand-tightened screw 40 is aligned with the connecting rod 30, and the two are connected by rotating the hand-tightened screw 40, completing the hanging and storage of the external items. The back clip 60 can be used to clip onto bags, belts, and other objects for carrying without the need for additional mechanical structures, providing a simple and convenient implementation method. This utility model has the following embodiments: Example

[0027] This embodiment provides a connection method. (See reference...) Figure 2 The first sidewall 10 and the second sidewall 20 are arranged opposite to each other, and the same side of the first sidewall 10 and the second sidewall 20 are connected to each other by the connecting part 90, and there is a gap between the two on the other side. Alternatively, the first sidewall 10 and the second sidewall 20 can be set as an integral structure. The connecting rod 30 and the hand screw 40 are respectively provided on the first sidewall 10 and the second sidewall 20. The connecting rod 30 is horizontally positioned on the side of the first sidewall 10 facing the second sidewall 20 and connected to the housing 11. The hand-tightening screw 40 is horizontally positioned on the second sidewall 20 and extends towards the connecting rod 30, forming a relative arrangement between the connecting rod 30 and the hand-tightening screw 40. The connecting rod 30 and the hand-tightening screw 40 are detachably connected between the first sidewall 10 and the second sidewall 20. The hand-tightening screw 40 can be rotated to separate from the connecting rod 30 and detach from the second sidewall 20. Since the second sidewall 20 is made of leather, it can be moved away from the first sidewall 10. Lateral movement increases the distance between the two, allowing external items (such as keys, pendants, USB drives, etc.) to be hung on the connecting rod 30 via through holes or lanyards. This also allows for the hanging of multiple external items at once. When the passage needs to be closed, by bringing the second sidewall 20 closer to the first sidewall 10, the hand screw 40 can be placed at the position where it mates with the connecting rod 30. Turning the hand screw 40 will reconnect the two and confine the external items to the connecting rod 30, thus completing the quick storage and carrying of external items without any additional pressing action, and will not injure the user's hands. Furthermore, the first sidewall 10 or the second sidewall 20 is also provided with a back clip 60. In this embodiment, the back clip 60 is disposed on the first sidewall 10 for clamping other objects. The back clip 60 includes a spring piece 61 and a base 62. The base 62 is disposed on the outer surface of the first sidewall 10 away from the second sidewall 20. One end of the spring piece 61 is connected to the base 62 by a fixing screw 63, and the other end has a first distance between it and the outer surface of the first sidewall 10, for forming a clamping structure. Preferably, the spring clip 61 bends and extends along the extension direction of the first sidewall 10, so that the first distance increases, decreases and then increases again. At the point where the first distance is the smallest, a tight connection with other objects can be achieved, so that it will not easily fall off. In this way, external items can be connected with other objects (such as bags, belts, pockets, etc.). Compared with the original hanging ring, it is applicable to a wider range of objects, making it convenient to carry external items for movement. Moreover, taking out the back clip 60 requires no other operation, which is very convenient. For details, please refer to Figure 3 and Figure 4 The box body 11 is hollow inside. A first through hole 1122 is provided on the side facing the second side wall 20. A second through hole 21 is provided on the second side wall 20. The first through hole 1122 and the second through hole 21 are arranged opposite to each other. The connecting rod 30 includes a nut 31 and an outer screw 32. The outer screw 32 is used to hang external items. The nut 31 and the outer screw 32 are connected to each other to form a whole. The nut 31 abuts against the outer periphery of the first through hole 1122 in the mounting groove 1121 for limiting the position. The outer screw 32 extends out of the first through hole 1122 and is set close to the hand screw 40. The hand-tightening screw 40 has a disc 41, a rotating part 42, and an inner screw 43. The rotating part 42 and the inner screw 43 are respectively arranged on both sides of the disc 41. The rotating part 42 is connected to the disc 41 through a rotating shaft and can be rotated to an angle perpendicular to the disc 41, making it convenient for the user to pinch. After use, it can also be rotated back for storage. The disc 41 abuts against the side of the second sidewall 20 facing away from the first sidewall 10 and is provided corresponding to the second through hole 21. The rotating part 42 is provided on the side of the disc 41 away from the second sidewall 20 and is connected to the disc 41. The user can hold the rotating part 42 to rotate the inner screw 43. The inner screw 43 is connected to the disc 41 and passes through the second through hole 21, extending toward the inside of the first sidewall 10. The outer screw 32 is hollow inside and has threads on its inner wall. The inner screw 43 has threads on its surface that mate with the inner screw 32. When the rotating part 42 is rotated, the outer screw 32 and the inner screw 43 can be opened and closed to each other, so as to connect or separate the connecting rod 30 and the hand screw 40. In this way, the traditional keychain structure that requires a snap ring or spring hook is avoided, reducing the pressing action and the problem of difficulty in removal. It also avoids the loss or unusability of items due to the failure of traditional springs. It not only makes it easier to store external items, but also makes it more durable. The back clip 60 forms a clamping structure with the first side wall 10 through its own metal properties and structural design. It does not rely on other elastic elements for clamping and is also durable and easy to use, providing a wider range of application scenarios. Example

[0028] In conjunction with Embodiment 1, this embodiment provides an installation method. (See reference...) Figure 5 and Figure 6 The first sidewall 10 is provided with a box body 11, which includes a plastic top cover 111 and a metal bottom shell 112. The plastic top cover 111 is located on the inner surface of the first sidewall 10 facing the second sidewall 20. The metal bottom shell 112 is connected to the plastic top cover 111 and surrounds it to form a receiving cavity 113. The receiving cavity 113 can hold other items, such as buzzers, batteries, control devices, AI devices, etc., and plays a role in storage and protection. The housing 11 is located between the first side wall 10 and the second side wall 20. The metal bottom shell 112 is provided with a mounting groove 1121. The side wall of the metal bottom shell 112 facing the second side wall 20 is provided with a first through hole 1122. The first through hole 1122 is located in the mounting groove 1121. When installing the connecting rod 30, the external screw 32 enters the first through hole 1122 through the mounting groove 1121, so that the nut 31 abuts against the inner wall surface of the metal bottom shell 112. The mounting groove 1121 provides the installation path of the external screw 32 and has the functions of limiting and guiding, making the installation of the connecting rod 30 faster, reducing the difficulty of production and assembly, and also saving production costs. The second sidewall 20 has a groove 22 on the side facing away from the first sidewall 10. The second through hole 21 is located in the groove 22. The groove 22 can accommodate the disc 41, making it easier to install the hand-tightening screw 40. It can be quickly positioned through the groove 22 when frequently used.

[0029] Based on the foregoing embodiments, refer to Figure 7 The keychain 100 includes a connecting part 90, with its two ends connected to the first side wall 10 and the second side wall 20 respectively, forming a structure in which one end of the first side wall 10 and the second side wall 20 are connected to each other and the other end is opened and closed through the connecting rod 30 and the hand screw 40. Alternatively, the connecting part 90 can be integrally set with the first side wall 10 or the second side wall 20. A protrusion 91 for threading a hanging rope is provided at the top of the connecting part 90. A hanging rope can be hung on the third through hole 92 of the protrusion 91, and the keychain 100 can be hung on other objects (such as mobile phones, belts, etc.), which greatly enriches the application scenarios of the keychain 100.

[0030] Based on the aforementioned embodiments, the keychain 100 also includes a buzzer assembly 70 and a battery cell 80. Both the buzzer assembly 70 and the battery cell 80 are located inside the housing 11, and a button 71 is provided on one side wall of the housing 11.
