- multiple fixing devices 4, for the frame 2 of loudspeaker to be fixed to support plate 3.
With reference to figure 2, frame 2 is included from the outstanding flange 20 of frame 2.One connector is set in each flange 20 21, for receiving fixing device 4.
Each connector 21 is included through flange 20 to form the first through hole 22 at first end edge 25.Wheel shaft (shank) 23 set around first through hole 22 and protruded from flange 20 along the direction opposite with support plate 3.Wheel shaft 23, which has, to be worn Cross the hole 24 (as shown in Figure 1) of wheel shaft 23.
First end edge 25 is limited on wheel shaft 23, and circumferential rib 26 is protruded with shape from the first end edge 25 of wheel shaft Into holding tooth.
Collar 27 sets around first through hole 22 and is protruded from flange 20 along the direction opposite with the wheel shaft 23.Axis Ring 27 defines the pedestal of the first through hole 22 around flange.
With reference to figure 1, support plate 3 includes being used for multiple second through holes 30 for receiving fixing device 4.
With reference to figure 3 and Fig. 4, fixing device 4 includes the intermediate plate 50 with axis A, and the axis is perpendicular to intermediate plate and wears Cross the center of intermediate plate.
First joint element 6 and the second joint element 7 protrude round about from intermediate plate 50.
First joint element 6 includes two the first elastic fins 60, they parallel to intermediate plate axis A and relative to The axis A of intermediate plate is arranged on the opposite position of diameter.By this way, freedom is left between two the first elastic fins 60 Space S so that elastic fin can freely curve inwardly in free space S.
Each first elastic fin 60 of first joint element includes outstanding holding tooth 61, and appearance is limited with this Rank 62.There is the groove for forming " C- shapes " housing in step 62.
Intermediate plate 50 and the height for keeping the distance between step 62 of tooth slightly above wheel shaft 23.
The holding tooth 61 of the elastic fin of first joint element has by the first outer cone surface 63 and the first inner conical table The conical by its shape that face 64 limits, these conical surfaces are engaged with circular second end edge 65.Therefore, keep tooth 61 that there is court The conical by its shape reduced to the thickness at the second end edge 65 of tooth.
Second joint element 7 includes the bar 70 that the direction of the axis A from intermediate plate 50 along intermediate plate protrudes.
The bar 70 of second joint element is terminated in from the radially projecting head 71 of bar 70.
Two the second elastic fins 72 are protruded from the head of the bar of the second joint element towards intermediate plate 50.Second engagement The elastic fin of element be arranged on relative to the axis A of intermediate plate be aligned with the first elastic fin 60 of the first joint element it is straight The opposite position in footpath.
Each second elastic fin 72 of second joint element has second connected by inclined 3rd terminal edge 75 The conical by its shape that 73 and second inner conical surface 74 of outer cone surface limits.Second elastic fin 72 of the second joint element has From head 71 towards the increased conical by its shape of thickness of the 3rd terminal edge 75 of elastic fin.
Preferably, the 3rd terminal edge 75 of each elastic fin of the second joint element relative to intermediate plate 50 inclination Angle [alpha] is 30 °~60 °.
Advantageously, the 3rd terminal edge 75 of each elastic fin of the second joint element has notch or knurled surface, To be adjusted to the different-thickness of support plate 3.
With reference to figure 1, Fig. 5~Fig. 7, the assembling to fixed sleeve part 1 is described.
First joint element 6 of fixing device is inserted into the first through hole 22 of the connector of speaker frame.
The inner surface of the first outer cone surface 63 and wheel shaft 23 of the holding tooth 61 of the elastic fin of first joint element rubs Wipe, and the 60 inside elastic bending of the first elastic fin.When the step 62 for keeping tooth exceedes the side of the wheel shaft of the connector of frame During the circumferential rib 26 of edge, the first elastic fin 60 returns resiliently to home position, and the side of the wheel shaft of the connector of frame The circumferential rib 26 of edge is engaged with the housing 68 for the step for keeping tooth.In this case, the intermediate plate of fixing device 50 In the housing limited by the collar 27 of frame.Therefore, fixing device 4 is firmly held in the connector 21 of frame.
Second joint element 7 of fixing device is inserted into the second through hole 30 of support plate.The elasticity of second joint element The inner surface friction of the first outer cone surface 63 and the second through hole 30 of support plate of fin, and the second elastic fin 72 is inside Elastic bending.When the 3rd terminal edge 75 of elastic fin exceedes the second through hole 30 of support plate, 72 bullet of the second elastic fin Original position is returned to property, the 3rd terminal edge 75 of the elastic fin of the second joint element stops in a manner of keeping support plate Lean against on the edge of the second through hole 30 of support plate.
First joint element is fixed to support plate fixed to the fixed operation in support frame and by the second joint element Fixed operation be all manually to carry out, it is not necessary to use any instrument, simply by fixing device 4 is manually pushed to raise The frame 2 of sound device and manually push fixing device 4 to support plate.
In order to make speaker frame be disengaged with fixing device 4, it is only necessary to which two the first elastic fins 60 are inwardly pushed away It is dynamic so as to keep the circumferential rib 26 of the wheel shaft of the disengaging frame of housing 68 of the step of tooth, frame is pulled relative to support plate 3.This The operation of sample can be without using any instrument, by two elastic fins for keeping the first joint element between thumb and forefinger Fixation tooth 61 carry out manually.
By this way, without using any instrument, the frame 2 of loudspeaker is removed from support plate, will not be by fixation Retaining element on frame leaves.
With reference to figure 8 and Fig. 9, the embodiment of the utility model is illustrated, wherein, the frame 2 of fixed sleeve part is Babinet for the antenna amplifier antennafire of vehicle.
In this case, frame 2 always has flange 20, and wherein first through hole 22 is present in this, is used for so as to be formed The connector 21 of fixing device 4.In this case, first end edge 25 is always formed around first through hole 22, so as to Keep the first elastic fin 60 of the first joint element of fixing device.
Many can be carried out to the present embodiment of the utility model to change and modifications, these embodiments are in expert in the art Can and scope in, all fall under any circumstance within the protection scope of the present utility model.
