detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

Referring to Fig. 1 to Fig. 3, the utility model provides a portable alarm device 100, which can be used by users to give an alarm in case of emergency. The portable alarm 100 includes a housing 20 , an alarm circuit (not shown in the figure, the same below) disposed in the housing 20 , and a plug 50 that cooperates with the alarm circuit to realize the connection and disconnection of the alarm circuit.

A relief hole 10 is opened on the casing 20 , and a main board 30 is arranged inside the casing 20 .

The alarm circuit is integrated on the main board 30 and includes a socket 40 .

The plug 50 is rod-shaped, one end of which is inserted into the socket 40 through the relief hole 10 , and the other end is exposed outside the housing 20 . And the plug 50 is configured to turn on the alarm circuit when it is pulled out and moves axially toward the outside of the housing 20; when it moves axially toward the socket 40, it is turned off. Open the alarm circuit.

In order to prevent the plug 50 from being completely pulled out from the housing 20 when the alarm is in use, a limiting boss 501 is formed on the end of the plug 50 away from the socket 40, and the outer surface of the limiting boss 501 is The diameter is larger than the diameter of the relief hole 10, and is located in the housing 20, so that when the plug 50 is pulled out, the limit boss 501 stops at the relief hole, preventing the insertion The plug 50 is fully withdrawn.

In order to avoid damage to the socket 40 when the plug 50 is fully inserted into the housing 20, a plug head 502 is formed at the end of the plug 50 away from the socket 40, which is located outside the housing 20 and outside the housing 20. The diameter is larger than that of the relief hole 10, so that when the plug 50 is inserted (that is, the plug 50 moves toward the socket 40), it stops outside the housing 20 to protect the plug 50.

Therefore, compared with the existing portable alarm, the portable alarm 100 of the present invention can prevent the plug 50 from being completely pulled out from the housing 20 in addition to realizing the alarm function, preventing the main body of the alarm and/or The loss of the plug 50 avoids waste in use. In addition, it prevents the socket 40 from being damaged due to excessive insertion of the plug 50 and protects the alarm. The product design of the portable alarm 100 is more user-friendly and also enhances the practicality.

Preferably, the plug 50 is a cylinder, the limiting boss 501 and the plug head 502 are cylinders, and the cylinder is conducive to the stretching or interpolation of the plug 50 and prevents it from being stuck.

Further, the portable alarm also includes an anti-return spring 60 that prevents the plug 50 from swinging left and right and drives the plug 50 back to disconnect the alarm circuit when the outward pulling force on the plug 50 disappears or weakens.

Preferably, the anti-return spring 60 is a compression spring, which is sleeved on the plug 50, and one end is fixedly connected to the limiting boss 501, and the other end is connected to the socket 40 facing the limiting boss. The platform 501 is provided outside the socket boss (not numbered).

When the alarm circuit of the portable alarm 100 is in an open circuit state, and the user does not apply an external pulling force to the plug 50, the compression spring is in a compressed state and exerts a certain elastic force on the plug 50. The elastic force is not greater than the resultant force between the gravity of the plug itself and the friction between the plug, the socket and the housing, so that the plug will not pop out automatically under the action of the elastic force and turn on the alarm circuit. When the plug 50 is pulled out by the user to give an alarm, the compression spring is in the released state under the tension, but the spring is still in the compressed state at this time. When the user's tension disappears, the plug will 50 is still kept in a tight state under the elastic force of the compressed compression spring, so that the alarm circuit is kept on and continues to alarm.

Preferably, the housing 20 includes a bottom case 201 and a face case 202, a buzzer device (not shown in the figure, the same below) is provided between the face case 202 and the main board 30, and the main board 30 is integrated with A power module (not shown, the same below), the socket 40 is electrically connected to the power module, and the buzzer is electrically connected to the socket 40, so that when the plug 50 is pulled out and the alarm circuit is connected , the power module can supply power to the buzzer device through the socket 40 .

Preferably, the front shell 202 is snap-connected with the bottom shell 201, which also facilitates production and assembly.

Please refer to FIG. 4 , further, one of the bottom shell 201 and the face shell 202 is provided with at least one nut stand or threaded hole, and the other of the bottom shell 201 and the face shell 202 is provided with a corresponding nut stand or threaded hole. Hole 205, to pass through counterbore 205 by screw 206 and be connected with nut column or threaded hole, strengthened the anti-beating and anti-disassembly effect of alarm in case of emergency.

In its implementation manner, the face shell 202 and the bottom shell 201 may also be connected only by threads.

Preferably, the bottom case 201 includes a side plate 203, the power module includes a battery (not shown in the figure, the same below) and a circular ring 204 connected to a gap opened on the side plate, one end of the circular ring 204 is connected to The bottom case 201 is pivotally connected, and its other end is fastened to the bottom case 201 by a screw 206, so that the ring 204 can be opened to replace the battery when the battery is dead (or low).

More preferably, the power module includes a rechargeable battery and its matching circuit (not shown in the figure, the same below), and the bottom case 201 is provided with a socket electrically connected to the matching circuit (not shown in the figure, the same below), So that when the power of the rechargeable battery is low or out of power, an external power source can be connected to store electricity for the rechargeable battery.

Preferably, the plug head 502 is provided with a through hole 503 passing through its outer periphery, which is used to pass through accessories including but not limited to ropes, metal chains or eyelets, so as to facilitate the pulling of the plug, and facilitate the insertion of the plug head. The portable alarm 100 is mounted on a bag or a key chain, which is convenient to carry and use.

The foregoing is only a partial implementation of the utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can also be made without departing from the principle of the utility model. Retouching should also be regarded as the scope of protection of the present utility model.
