Abstract
The utility model discloses a fast installing structure of an automobile loudspeaker. The fast installing structure of the automobile loudspeaker comprises a loudspeaker and an installing support, wherein the loudspeaker and the installing support are arranged opposite to each other. The fast installing structure of the automobile loudspeaker is characterized in that an installing hole and a fixing column are distributed on the installation opposite face of the loudspeaker, an installing hole and a fixing hole corresponding to the installing hole and the fixing column on the installation opposite face of the loudspeaker respectively are formed in the installation opposite face of the installing support, the fixing column is of a cone structure formed by injection molding of plastics, the large-end portion of a conical body is in interference fit with the fixing hole, the small-end portion of the conical body is used for penetrating through the fixing hole, and the small-end portion of the conical body is in clearance fit with the fixing hole. According to the installing structure of the automobile loudspeaker, due to the fact that positioning columns are in an interference matched mode, the position of the installing hole can be calibrated rapidly to finish the interference matching, one staff can assemble a product quickly, working time is reduced, and working efficiency is improved. The purpose that the working state is changed form a random mode to an accurate mode is achieved, the time of the staff is saved to a great extent, the staff can use the time to finish other work, and working efficiency is improved.
Description
Technical field
The utility model relates to the auto loud hailer field, relates in particular to a kind of quick attach structure of auto loud hailer.
Background technology
Current most auto loud hailer assembling, locked by screw, in the completed knocked down products process, at first, to loud speaker mounting hole and mounting bracket hole, carries out the check and correction of Kong Yukong, then carries out first fixed orifice and carry out screw and fix.Then proofread other mounting holes, then carry out screw and fix.When loud speaker mounting hole and the check and correction of mounting bracket hole, consider the position of mounting hole, need to carry out the adjusting time.
When assembling product, the employee wants as early as possible the loud speaker mounting hole to be fixed, need two employees to carry out completing assembling product work simultaneously, an employee carries out loud speaker mounting hole and the check and correction of mounting bracket hole, and holding up loud speaker, to prevent that loud speaker from dropping, another one employee carries out screw and fixes.Also to consider the position of hookup wire simultaneously.Work efficiency obviously reduces like this.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, a kind of quick attach structure of auto loud hailer is provided, thereby has saved the more time, during assembling, needs an employee just can complete fast assembling product, increases work efficiency.
The utility model is achieved through the following technical solutions:
A kind of quick attach structure of auto loud hailer, include involutory loud speaker and mounting bracket mutually, it is characterized in that: described loud speaker is installed on involutory surface and is distributed with mounting hole and fixed leg, the involutory surface of described mounting bracket is provided with mounting hole and the fixed leg installed on involutory surface with loud speaker and distinguishes corresponding mounting hole and fixed orifice, described fixed leg is for adopting the cone structure of plastic-injection moulding, and adopt interference fit between the large end of cone and fixed orifice, the small end of cone is used for through between fixed orifice and fixed orifice, adopting free-running fit.
Fixed leg and the fixed orifice on the mounting bracket involutory surface that described loud speaker is installed on involutory surface are three, and one of them fixed leg is distant from two other fixed leg.
The utility model has the advantages that:
The utility model, by registration mast interference coupling, can be proofreaded rapidly position of mounting hole, completes the interference coupling, and an employee just can complete rapidly assembling product, reduces work-hours, increases work efficiency.Realization " arbitrarily to accurate " when work makes the employee find time largely, completes other work, increases work efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the loadspeaker structure schematic diagram.
Fig. 3 is the mounting support structure schematic diagram.
The specific embodiment
Referring to accompanying drawing, a kind of quick attach structure of auto loud hailer, include involutory loud speaker 1 and mounting bracket 2 mutually, loud speaker 1 is installed on involutory surface and is distributed with three mounting holes 3 and three fixed legs 4, and one of them fixed leg is distant from two other fixed leg, the involutory surface of mounting bracket 2 is provided with mounting hole 3 and the fixed leg 4 installed on involutory surface with loud speaker 1 and distinguishes corresponding mounting hole 5 and fixed orifice 6, fixed leg 4 is for adopting the cone structure of plastic-injection moulding, and adopt interference fit between the large end of cone and fixed orifice 6, the small end of cone is used for through between fixed orifice and fixed orifice, adopting free-running fit.
Its principle is: cardinal principle adopts 3 one side interference fixation principle, and by add three fixed legs on the loud speaker plastic parts, three fixed orifices are added in the mounting bracket relevant position; When the product loud speaker is assembled, first mounting bracket and vehicle body are assembled, be fixed post and the mounting bracket fixed orifice is mated, then carry out the mounting hole screw and fix, realize one man operation, save time, increase work efficiency.When auto loud hailer and mounting bracket are assembled, do not need two employees to finish the work.But, by add three fixed legs on loud speaker, three fixed legs and mounting bracket fixed orifice interference coupling, just can actv. control the position of screw fixed hole.In three fixed legs, one of them fixed leg is distant from two other fixed leg, thereby an obvious mark is arranged, and distinguishes the position of hookup wire.
Be characterized in:
1, use 3 one side interference fixation principle, loud speaker plastic parts (one side contacts with mounting bracket) is formed to three cones.The purposes of three cones is as described below:
1., cone one end circular diameter is less than the fixed orifice on mounting bracket, its purposes is in the loud speaker assembling, is convenient to fixed leg and can matches rapidly the fixed orifice on mounting bracket.
2., cone one end circular diameter is larger than the fixed orifice on mounting bracket, realizes the interference fixation; Its purposes is in the loud speaker assembling, and the coupling interference is fixed on above mounting bracket loud speaker, and assembler just can be vacateed hand, carries out screw fastening.
3., fixed leg is difficult for too much, also being difficult for very few; Selecting three fixed legs, is because 3 can be played good fixation, is not easy distortion, is not easy off normal.
4., three fixed legs and mounting bracket fixed orifice interference coupling, just can actv. control the position of screw fixed hole, make mounting hole and mounting bracket screwing hole on loud speaker be not easy off normal, not there will be fastening not screwing or screw off normal.Also play dual fixation simultaneously.
2, in the time of vehicle body assembling loud speaker, once fixed leg and mounting bracket fixed orifice interference coupling; Loud speaker just is not easy to come off, thereby vacates staff, carries out screw fastening.Make two work that the employee can complete originally, one
Individual employee just can complete; Compare, the time of using is shorter than the time of two employee's assemblings.
3, fixing loud speaker rapidly, carry out screw to loud speaker rapidly and fix, and shortens working hours, and increases work efficiency.
4, by product is improved, for loud speaker and mounting bracket, assembled, carried out experimental test.Evidence has original two employees per hour to assemble 80 groups, brings up to and per hour assembles 143 groups; Improved nearly half work efficiency.When assembling, can vacate the more time like this, complete other work.
