Description

Technical Field

[0001] The utility model relates to the field of hearing aid charging boxes, in particular to a hearing aid charging box. Background Art

[0002] A hearing aid is a small amplifying device for the hearing-impaired to compensate for hearing loss. A hearing aid charging box is a special device for charging the hearing aid. A hearing aid using a rechargeable battery only needs to be placed in a special charging base when sleeping at night to complete the charging of the hearing aid. It is easy to use, and a single charge of the hearing aid can basically meet the use of a day. The existing charging box needs to be charged in time after the power is used up. When the charging box is charging, it is easy to cause the connector and the slot to loosen due to external tension, affecting the charging and causing the charging box to have no power, affecting the charging and use of the hearing aid, and it is inconvenient to limit the connector, which has brought certain adverse effects to people's use process. For this reason, we propose a hearing aid charging box. Utility Model Content

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] This embodiment is a hearing aid charging box.

[0017] like Figure 1-3 As shown, it includes a box body 1, a cover plate 2 is arranged on the upper outer surface of the box body 1, a hinge 3 is arranged between the cover plate 2 and the box body 1, a slot 6 is opened at the lower end of the front outer surface of the box body 1, a connector 5 is arranged at the front end of the slot 6, a power cord 4 is arranged on the front outer surface of the connector 5, a fastening mechanism 7 is arranged in the middle of the front outer surface of the box body 1, the fastening mechanism 7 includes an anti-slip pad 8, a limit rod 9, a spring 11, a fixing plate 12, a connecting rod 13, a hole slot 14 and a key rod 15, and the fixing plate 12 is fixedly installed on the box body 1, two groups of holes and grooves 14 are respectively opened on both sides of the upper outer surface of the fixing plate 12, the key rod 15 is located in the middle of the hole and groove 14, the connecting rod 13 is fixedly installed on the upper outer surface of the two groups of key rods 15, the limiting rod 9 is fixedly installed on the lower outer surface of the key rod 15, the spring 11 is located between the fixing plate 12 and the limiting rod 9, and the anti-slip pad 8 is located on the lower outer surface of the box body 1; the key rod 15 and the hole and groove 14 are slidably connected, and the limiting rod 9 is elastically connected to the fixing plate 12 through the spring 11.

[0018] The connector 5 and the slot 6 are plugged together, and the anti-skid pad 8 and the box body 1 are bonded together.

[0019] It should be noted that the utility model is a hearing aid charging box. When the box body 1 needs to be charged, the connecting rod 13 is pulled upward to drive the key rod 15 to slide along the hole groove 14, compress the spring 11, move the limit rod 9 upward, and insert the connector 5 at one end of the power cord 4 into the slot 6. After the connector 5 is tightly connected to the slot 6, the connecting rod 13 is released, and the key rod 15 is driven to slide along the hole groove 14 under the resetting action of the spring 11, and the limit rod 9 is lowered and moved to the front end of the connector 5, thereby limiting the connector 5. It is convenient to limit the connector 5 and to fit the connector 5 closely to the slot 6, thereby preventing the connector 5 from loosening and affecting charging.
