Sound box handle mechanism and assembly method thereof

Abstract

The invention discloses a sound box handle mechanism and an assembly method thereof. The sound box handle mechanism comprises the structure that an open slot (2) is arranged on a sound box body (1); a slide plate (3) is connected on the open slot (2) in a slide mode; long strip-shaped inclined blocks (4) are arranged at two sides of the open slot (2); slide slots (5) of which shapes matching the shapes of the inclined blocks (4) are arranged at two sides of the slide plate (3); a hollowed structure (16) for penetration of fingers is arranged on the slide plate (3); a cross rod (6) for holding is arranged on the hollowed structure (16) at the side close to the opening of the open slot (2); an inserting block (7) is arranged on the slide plate (3) at the side away from the cross rod (6); a blind hole (8) for inserting the inserting block (7) is arranged on the open slot (2); and the shape of the blind hole (8) matches that of the inserting block (7). The sound box handle mechanism and the assembly method thereof are low in production cost and high in connection strength.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to an audio handle mechanism and an assembly method thereof. Background technique [0002] At present, in order to facilitate the grabbing of the speaker when it is moving, a handle mechanism is usually provided on the speaker. There is a gap between the bar, the cross bar and the sound box casing, people can hold the cross bar, and fingers can pass through the gap between the cross bar and the sound box casing. In the prior art, it is common for the sound box shell to be made of plastic parts, while the cross bar and the protrusion are often integrally formed by injection molding with the sound box shell. However, there is a disadvantage in the handle mechanism formed by injection molding. When people hold the cross bar, due to the gravity of the sound, the gravity of the whole sound will be decomposed to the two ends of the cross bar. It will be concentrated at the junction of th...

Problems solved by technology

[0003] The handle mechanism in the prior art is usually integrally formed by injection molding. Due to the existence of crossbars, the structure of the injection mold is bound to be extremely complicated. It is necessary to set up multiple lateral core-pulling structures to form features similar to hollow structures. Furthermore, the assembly of the handle mechanism in the prior art is simplified, but the overall cost of the handle mechanism in the production and processing process becomes higher. For example, the lateral core-pulling mechanism is an item that increases design and test costs during the design process.

In addition, due to the presence of shrinkage cavities and porosity at the stress concentration point during the integral molding process, it is very easy to break due to excessive load at the stress concentration point; therefore, the handle mechanism in the prior art has high production costs, The defect that the connection strength is not high enough
