Description

Technical Field

[0001] The utility model relates to the technical field of anti-loss devices, in particular to a keychain anti-loss device. Background Art

[0002] In modern society, people need to carry many items with them during daily travel, such as wallets / handbags / card holders, key chains, ticket holders, etc. However, due to various reasons, these items carried with them often "disappear" at a certain moment. For example, people with a poor memory forget to bring their keys when going out, forget to bring their wallets when eating, or inadvertently drop and lose their personal belongings or have them stolen by others. These inadvertent mistakes will bring great inconvenience and loss of personal interests to users, and many people are troubled by them.

[0003] To solve the above problems, many anti-loss device products have emerged on the market. Among them, most anti-loss devices use wireless methods. As long as they are placed together with wallets, keys, luggage, or even hung on children or pets, they can be quickly retrieved through a mobile phone. The main principle of the wireless anti-loss device is to judge whether the item is still within your safe range by the change in distance. The specific process is as follows: The anti-loss device is built-in with a Bluetooth module, which is wirelessly paired with the mobile phone Bluetooth through the Bluetooth module. The anti-loss device will not alarm within the range where it can receive the mobile phone Bluetooth wireless signal. Once the anti-loss device and the mobile phone with which a wireless connection has been established are separated by a certain distance or the anti-loss device loses the mobile phone Bluetooth signal, the anti-loss device or the exclusive application program of the anti-loss product installed on the mobile phone will issue an alarm to remind the user and retrieve the item.

[0004] The existing wireless anti-loss device products have many forms and are getting smaller and smaller in size, including those with cords such as keychain types or other types with cords, and cordless forms such as button types, U disk types, watch types, etc. These anti-loss devices can solve the problem of item loss to a certain extent, but they only have the function of an anti-loss device, which means that the user still needs to carry an additional anti-loss device, and the integration degree is not high.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] The following details the principle and structure of the present utility model in conjunction with the drawings and embodiments.

[0030] There are many product forms of existing wireless anti-loss devices, and the volume is getting smaller and smaller. They include those with cords such as keychain types or other types with cords, and cordless forms such as button types, USB flash drive types, watch types, etc. These anti-loss devices can solve the problem of item loss to a certain extent, but they only have the function of an anti-loss device. It is equivalent that the user still needs to carry an additional anti-loss device, and the integration degree is not high.

[0031] In response to this, the present utility model proposes a keychain anti-loss device, which directly integrates the anti-loss device on the keychain, enabling the keychain to not only hang keys but also have the anti-loss function. Moreover, since the anti-loss module is directly integrated on the housing of the keychain, compared with the traditional anti-loss device that needs to be connected in series on the keychain, it can reduce the collision between the anti-loss module and the key and avoid damage to the anti-loss module.

[0032] As Figure 1 shown, the present utility model proposes a keychain anti-loss device, which specifically includes: a housing 1, an anti-loss module 4, a battery 5, a battery cover 6 and a connecting part. The housing 1 is flat-shaped with a front side and a back side. The housing 1 is provided with a mounting hole 11 penetrating its front side and back side. The front side and the rear side of the housing 1 are arc-shaped. A hook-shaped buckle body 2 is provided at a position on the right side close to the rear side. A push switch 3 cooperating with the buckle body 2 is provided at a position on the right side close to the front side. When the push switch 3 is pressed and rotates into the buckle body 2, when released and reset, it forms a closed loop with the buckle body 2 and one side surface of the housing 1; and when the buckle body 2 and the push switch are reset, the overall outer contour is oval-shaped; the anti-loss module 4 is installed in the mounting hole 11. The anti-loss module 4 integrates a main board, a Bluetooth module, a buzzer, etc. of a traditional anti-loss device inside. The middle part of the front surface of the anti-loss module 4 protrudes from the mounting hole position on the front surface of the housing. The back surface of the anti-loss module 4 is provided with a battery slot for installing a button battery 5. The battery cover 6 is installed at the mounting hole position on the back surface of the housing to cover the mounting hole and is provided with a spring piece corresponding to the button battery.

[0033] It should be noted that the structural settings of the left side surface and the right side surface of the housing 1 are not very different from the traditional keychain structure. The push switch is also a commonly used component in keychains and is not the focus of protection of the present utility model. Its specific structural settings include a torsion spring, etc. (for example, there are two spaced support pieces at the position where the push switch is installed on the housing. Through holes are provided at opposite positions on the support pieces for passing through a rotating shaft. One end of the push switch with the rotating shaft is located between the two support pieces, and both ends of the rotating shaft respectively pass through the through holes of the two support pieces. At the same time, a torsion spring is sleeved on the rotating shaft so that the push switch can be reset after being pressed inward), and the structure can also be clearly seen from the drawings.

[0034] In a specific embodiment, a retaining ring is provided along the edge of the mounting hole 11 close to the front surface of the housing. The front edge of the anti-loss module 4 is limited by the retaining ring, and the middle part of the front surface protrudes from the mounting hole.

[0035] In a specific embodiment, when the housing 1, the buckle body 2 and the push switch 3 are reset, the overall outer contour is oval-shaped, improving the holding feel.

[0036] In a specific embodiment, the mounting hole of the housing 1 is a circular mounting hole, and the outer contour of the anti-loss module 4 is correspondingly circular, so that the anti-loss module 4 can be directly inserted into the mounting hole. A clamping groove 21 is provided on the outer wall surface of the anti-loss module 4, and a buckle 12 that cooperates with the clamping groove 21 is provided on the inner wall of the mounting hole. The clamping groove 21 includes a vertical groove and a horizontal annular groove that are connected in sequence. The vertical groove extends from the front edge to the back edge of the anti-loss module 4, and the horizontal annular groove communicates with the end of the vertical groove and extends along the circumferential surface of the anti-loss module in an arc shape. During installation, the front side of the anti-loss module is facing up, and the back side of the housing is inserted into the mounting hole upward. First, the buckle on the inner wall of the mounting hole of the housing is aligned with the vertical groove, and then the housing is rotated so that the buckle on the housing 1 is snapped into the horizontal annular groove on the side of the anti-loss module from the end of the vertical groove, thereby connecting the housing and the anti-loss module.

[0037] The specific connection method between the battery cover and the housing is also a connection method of a buckle and a clamping groove. Specifically, the outer side surface of the battery cover is provided with a clamping groove that is the same as the outer side surface of the anti-loss module. The buckles on the inner wall of the mounting hole are divided into two groups that are spaced up and down. At the same time, the inner diameter of the inner wall of the mounting hole is also divided into two parts (the inner diameter of the upper part is smaller than that of the lower part). Among them, a part close to the front side of the housing is used to install the anti-loss module, and a part close to the back side of the housing is used to install the battery cover.

[0038] In a specific embodiment, an installation groove is provided on the left side surface of the housing 1. The connecting part includes: a connecting seat 71 and a connecting part in series. The connecting seat 71 is installed in the installation groove and is connected to the housing by screws. A through hole is provided on the connecting seat, and a threaded hole is provided in the installation groove on the left side surface of the housing. The screw can pass through the through hole of the connecting seat and be threadedly connected to the housing, so that the connecting seat 71 is connected to the housing 1, and the connecting part in series is connected to the connecting seat.

[0039] As Figure 1 、 4 shown, in the first embodiment, the connecting part in series is a circular ring 72. A ring sleeve through which the circular ring can pass is provided on the connecting seat 71, and the circular ring can be used to connect keys in series.

[0040] As Figure 2 、 3 shown, in the second embodiment, the connecting part in series is a leather sleeve 73. The two ends of the leather sleeve overlap, so that the leather sleeve looks like a water droplet from the side. The overlapping part of the two ends of the leather sleeve is inserted into the preset slots on both sides of the screw hole on the connecting seat, and the leather sleeve is fixed on the connecting seat by screws passing through the connecting seat and the overlapping part of the leather sleeve.
