[0002] At present, existing single-police equipment such as walkie-talkies, police communications, and law enforcement recorders are used frequently and require a longer battery life. However, due to the weight problem, batteries that are too large cannot be used. Therefore, some people have proposed police backup batteries to charge equipment such as walkie-talkies, police communications, and law enforcement recorders. However, the charging specifications of these types of equipment are different. During police operations, many different chargers or backup power supplies are often required. In particular, the charging ports of single-police equipment such as walkie-talkies are often multi-pin charging interfaces. Therefore, this situation poses a great challenge to the management and carrying of equipment. Some people have increased the battery life of equipment such as walkie-talkies by setting batteries on the back clip, but this has increased the load on users such as police officers and posed a great challenge to the user's physical strength.

The two elastic terminals 31 correspond to the positive and negative poles of the charging port of the electronic device, respectively, to supply power to the charging port of the electronic device. The interface is configured as a standard interface, and the interface 32 is electrically connected to the elastic terminal 31. Preferably, the standard interface 32 is a type-c interface, and can also be a USB interface or other existing universal standard interfaces.

[0027] By setting up the adapter component 3 and connecting the elastic terminal 31 to the standard interface 32, the back clip device can be adapted to any existing charger and power bank, thereby improving the charging versatility of electronic devices such as walkie-talkies, police communications, and law enforcement recorders. It has a simple structure, low cost, high reliability, and is easy to promote.

[0028] Specifically, in this embodiment, the electronic device is a walkie-talkie, so as to help the majority of existing walkie-talkie users unify the charging interface with other equipment or devices without having to modify or purchase new walkie-talkies. In other embodiments, the electronic device can also be an electronic device that needs to be shoulder-mounted, such as a law enforcement recorder, a police communication system, a PDA, etc., and such changes still fall within the scope of protection of the utility model.

[0029] The back clip assembly 2 includes a back clip cover plate 21 configured to be elastically rotated outward to open, a track 211 is provided in the back clip cover plate 21 along the length direction of the back clip cover plate 21, a locking tongue 22 is provided in the track 211, and the locking tongue 22 is configured to be switchable between a plurality of predetermined positions in the track 211. In this way, the clamping position and angle of the back clip device at various places of clothing such as the shoulder strap or armband of the user can be adjusted according to specific usage conditions by changing the position of the locking tongue 22 in the track 211, so that the user can adjust the clamping condition according to his or her own wearing condition.

[0030] Specifically, the track 211 is provided with four predetermined positions along the length direction of the track 211. In other embodiments, the number of predetermined positions may be two, three or more, and such structural changes still fall within the protection scope of the present utility model. The bottom of the lock tongue 22 has bosses 222 extending horizontally on both sides, and both sides of the predetermined position are provided with grooves 212 for inserting the bosses 222. One side of the bosses 222 is configured as an inclined surface to guide the bosses 222 into the grooves 212.

[0031] In some preferred embodiments, a through slot 221 is provided in the middle of the lock tongue 22, and the through slot 221 passes through the top of the lock tongue 22 so that the lock tongue 22 can be clamped to compress the width of the through slot 221, thereby changing the width of the lock tongue 22, causing the lock tongue 22 to move freely in the track 211.

[0032] A cover plate 23 is also provided above the track 211 to prevent the locking tongue 22 from falling out. The cover plate 23 and the upper surface of the track 211 are detachably connected, such as by screw connection, snap connection, etc.

[0033] In some preferred embodiments, through holes 12 are provided on both sides of the accommodating portion 1, and a snap-fit ​​portion 13 is provided in the through hole.

Specifically, the snap-fit ​​portion 13 can be integrally formed with the accommodating portion 1 by injection molding, and the elasticity of the material itself is used to achieve elastic connection. In some other embodiments, other existing connection methods such as bolt connection or connection through elastic parts can also be used, which will not be elaborated here.

[0034] In some other embodiments, see Figure 5 As shown, the bottom of the lock tongue 22 is provided with a slider 223 that is slidably connected to the track, and the cover plate 23 is provided with a slide groove 231 for the lock tongue 22 to pass through. The side wall of the slide groove 231 is provided with a plurality of grooves 232. A boss 222 for inserting and fixing in the groove 232 is provided between the corresponding lock tongue 22 and the slider 223. One side of the boss 222 is set to be inclined. A through groove 221 is provided in the middle of the lock tongue 22. The through groove 221 passes through the top of the lock tongue 22 so that the lock tongue 22 can be clamped and compressed to change the width of the through groove 221, so that the boss 222 can be disengaged from the groove 232, so that the slider 223 can move freely in the track. The cover plate 23 not only prevents the lock tongue 22 from disengaging, but also provides a predetermined position. By setting the slider 223, the sliding process is also made smoother and convenient to use.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
