The car loudspeaker core is characterized in that a fastening end face of the thread portion is provided with a backstop gear which is provided with 24 teeth. The car loudspeaker core is firmly connected to a loudspeaker vibrating reed and not prone to be loosened, and effectively improves quality and service life of a loudspeaker.
Description
Technical field
The utility model relates to a kind of horn trumpet, is specifically related to a kind of improvement invention of horn trumpet fuse.
Background technology
Horn trumpet is the obligato parts of automobile, and the quality of horn trumpet and service life are relative with the firmness that connects of horn vibrating reed with the loudspeaker fuse.The structure of loudspeaker fuse is very simple; Comprise iron core portion and threaded portion; Loudspeaker fuse and horn vibrating reed are performed such and connect: the inner hole sleeve of horn vibrating reed on the screw rod of loudspeaker fuse threaded portion, is screwed on the fastening end face that nut is pressed abd fixed on horn vibrating reed loudspeaker fuse threaded portion at screw rod then.The shortcoming of above-mentioned connection is, because vibration, the loudspeaker fuse is prone to generation with connecting of horn vibrating reed and becomes flexible, thereby influences the quality and the service life of loudspeaker.
Summary of the invention
In view of the deficiency that background technology exists, the purpose of the utility model is intended to provide a kind of the connection with horn vibrating reed firmly to be difficult for becoming flexible, and effectively improves the horn trumpet fuse in loudspeaker quality and service life.
The utility model is implemented through following technical scheme:
The horn trumpet fuse comprises iron core portion and threaded portion, it is characterized in that: the fastening end face of threaded portion is provided with locking tooth.
The horn trumpet fuse that the utility model provides; Because the fastening end face in the threaded portion has been provided with locking tooth; So; When horn vibrating reed is pressed abd fixed on the fastening end face by nut, just be difficult for becoming flexible, improved the connect firmness of loudspeaker fuse, thereby effectively guaranteed loudspeaker quality and long service life with horn vibrating reed.
As preferably, described locking tooth is provided with 24 teeth at fastening end face.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the constructional drawing of horn trumpet fuse;
Fig. 2 is the directional pattern of looking up of Fig. 1.
The specific embodiment
As illustrated in fig. 1 and 2, the horn trumpet fuse of the utility model by the whole cold-heading molding of cold heading technique, comprises iron core portion 1 and threaded portion 2, and the fastening end face 3 of threaded portion 2 is provided with locking tooth 4, and described locking tooth 4 is provided with 24 teeth at fastening end face 3.Because the fastening end face 3 in the threaded portion has been provided with locking tooth 4; So; When horn vibrating reed is pressed abd fixed on fastening end face just difficult becoming flexible of 3 last times by nut, improved the connect firmness of loudspeaker fuse, thereby effectively guaranteed loudspeaker quality and long service life with horn vibrating reed.
