Abstract
The utility model discloses an anti-friction headphone which comprises two headphone casing bodies, two headphone bodies and a connecting lantern ring. Each headphone casing body comprises a body accommodating part and a connecting part. The connecting part is connected with the upper end of the body accommodating part. Headphone bodies are accommodated in corresponding body accommodating parts. Each connecting part is provided with an arc insertion cavity. Each insertion cavity is provided with an insertion cavity opening which is arranged at the upper end of each connecting part. At least one clamping table is convexly arranged on the inner wall, which is close to the inside, of each insertion cavity. A number of smooth bumps are respectively and convexly arranged on the inner sides of both ends of the connecting lantern ring. Both ends of the connecting lantern ring are respectively clamped and inserted into corresponding insertion cavities. The bumps are clamped and connected with the clamping table in a sliding manner. According to the utility model, the bumps of the anti-friction headphone can be clamped on the clamping table in a sliding manner, so that when up and down positions of the headphone casing bodies are adjusted, only friction between the bumps on the connecting lantern ring and the clamping table exists; friction between two smooth side walls of the connecting lantern ring is greatly reduced; and the anti-friction headphone is durable.
Description
Technical field
The utility model relates to dynamo-electric field, relates in particular to a kind of abrasion-proof head earphone.
Background technology
Head earphone is people's instruments of answering commonly used when using computer, and current head earphone comprises that two earphone cases and connect the collar, slide the respectively upper end of the earphone case that is connected in correspondence, the two ends of this connections collar.
Yet this head earphone is when reconciling the upper-lower position of earphone case, and the inside and outside sidewall of this connection collar is owing to constantly rubbing with earphone case, thereby the vestige that scratches easily occurs, has influence on its aesthetic appearance of earphone.
Therefore, demand a kind of energy urgently and reduce the inside and outside sidewall of the connection collar and the abrasion-proof head earphone of earphone case friction, thereby make for a long time Chang Xin of this head earphone.
The utility model content
The purpose of this utility model is to provide a kind of can reduce the inside and outside sidewall of the connection collar and the abrasion-proof head earphone of earphone case friction, thereby makes for a long time Chang Xin of this head earphone.
to achieve these goals, the technical solution of the utility model is: a kind of abrasion-proof head earphone is provided, comprise two earphone cases, two headset main body and one connect the collar, described earphone case comprises main body accommodation section and connecting portion, described connecting portion is connected to the upper end of described main body accommodation section mutually, described headset main body is placed in corresponding main body accommodation section, described connecting portion is provided with the slotting chamber of arc, described slotting chamber has the slotting chamber opening of the upper end of being located at described connecting portion, the inner inwall in described slotting chamber convexes with at least one Ka Tai, the inboard at the two ends of the described connection collar convexes with respectively some round and smooth salient points, block respectively in the slotting chamber that inserts in correspondence at the two ends of the described connection collar, described salient point slides and is connected on described Ka Tai.
The inner inwall in described slotting chamber convexes with Liang Katai.
Described Ka Tai is located at described slotting chamber near an end of described slotting chamber opening.
The lateral wall in the outside of described connecting portion has fabrication hole near described slotting chamber opening part, and described fabrication hole communicates with described slotting chamber.
Compared with prior art, the salient point of the utility model abrasion-proof head earphone slidably is arranged on described Ka Tai, thereby when making the upper-lower position of regulating earphone case, just connect the salient point on the collar and block between platform and rub, greatly reduced the friction that connects the collar two smooth side wall, made for a long time Chang Xin of this abrasion-proof head earphone.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Description of drawings
Fig. 1 is the structure chart of an angle of the utility model abrasion-proof head earphone.
Fig. 2 is the partial sectional view of an angle of the utility model abrasion-proof head earphone.
Embodiment
With reference to figure 1 and Fig. 2, the utility model abrasion-proof head earphone 100 comprises that two earphone cases 10, two headset main body (not shown) and connect the collar 30.
Described earphone case 10 comprises main body accommodation section 11 and connecting portion 12.Described connecting portion 12 is connected to the upper end of described main body accommodation section 11 mutually.Described headset main body is placed in corresponding main body accommodation section 11.Described connecting portion 12 is provided with the slotting chamber 121 of arc, and described slotting chamber 121 has the slotting chamber opening 1211 of the upper end of being located at described connecting portion 12.The inner inwall in described slotting chamber 121 convexes with at least one card platform 1212.In the present embodiment, the inner inwall in described slotting chamber 121 convexes with two card platforms 1212.The lateral wall in the outside of described connecting portion 12 has fabrication hole 13 near opening 1211 places, described slotting chamber, and described fabrication hole 13 communicates with described slotting chamber 121.
The inboard at the two ends of the described connection collar 30 convexes with respectively some round and smooth salient points 31.Block respectively in the slotting chamber 121 that inserts in correspondence at the two ends of the described connection collar 30.Described salient point 31 slides and is connected on described card platform 1212.
When using the utility model abrasion-proof head earphone 100, when the described connection collar 30 is not subjected to External Force Acting, described salient point 31 is arranged on corresponding card platform 1212, when needs are heightened the height of earphone case 10, to pressing down the described connection collar 30, elastic deformations occur and cross corresponding card platform 1212 downwards in the salient point 31 that originally was stuck on described card platform 1212, and after mixing up the position, the salient point 31 of salient point 31 tops that are positioned at that original card establishes moves down and is stuck on corresponding card platform 1212.When needs are turned down the height of earphone case 10, upwards draw the described connection collar 30, elastic deformation occurs and upwards crosses corresponding card platform 1212 in the salient point 31 that originally was stuck on described card platform 1212, after mixing up the position, the salient point 31 of salient point 31 belows that are positioned at that original card establishes up moves and is stuck on corresponding card platform 1212.
The salient point of the utility model abrasion-proof head earphone slidably is arranged on described Ka Tai, thereby when making the upper-lower position of regulating earphone case, just connect the salient point on the collar and block between platform and rub, greatly reduced the friction that connects the collar two smooth side wall, made for a long time Chang Xin of this abrasion-proof head earphone.
Abovely in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to the essence of the present embodiment.
