Abstract
The utility model discloses a horn fixing device which comprises a fastening device and two pressing feet which are symmetrically arranged on the two sides of the fastening device. The fastening device is used for fastening a horn on a base, and the two pressing feet are used for pressing on the upper surface of the horn in an abutting-against mode, so that the horn is pressed on the base in an abutting-against mode. A fastening position fixing structure is adopted for fixing the horn, so that operation is very convenient and saves labor, and meanwhile the horn can be fixed on the base in a fastening mode.
Description
Technical field
The utility model relates to a kind of loudspeaker fixture.
Background technique
The loudspeaker that existing village village is logical be fixedly very loaded down with trivial details, all by male rivet and female rivet, coordinate loudspeaker are fixed on down and cover, but loudspeaker are in the process of installing, all need the staff the expensive time to carry out combination and the assembling of male and female rivet, and utilizing the male and female rivet to assemble is to be not easy very much operation, and consumes very much artificial.
The model utility content
The technical problems to be solved in the utility model be for overcome in prior art utilize the male and female rivet fix loudspeaker be not easy very much the operation and consume very much artificial defect, a kind of loudspeaker fixture is provided.
The utility model solves above-mentioned technical problem by following technical proposals:
The utility model provides a kind of loudspeaker fixture, its characteristics are, two compression pin that it comprises a bayonet unit and is symmetricly set in described bayonet unit both sides, described bayonet unit is for being snapped in a base by loudspeaker, described two compress pin for being pressed on the upper surface of described loudspeaker, so that described loudspeaker are pressed on described base.
Preferably, described bayonet unit comprises two buckle pin and a fixing column, described two buckle pin are fixedly connected with described fixing column by the supporting post of a coupling respectively, to form respectively two grooves, described two grooves are for holding described loudspeaker and described base, and make described fixing column be pressed on the upper surface of described loudspeaker, described buckle pin is pressed on the lower surface of described base.
Wherein, spacing between each groove all is set to just can hold described loudspeaker and described base, like this, just can be so that the lower surface of described fixing column can tightly be pressed on the upper surface of described loudspeaker, the upper surface of described buckle pin can be held in the lower surface of described base, thereby just described loudspeaker is fastened on described base.Compress by described two the upper surface that pin tightly is pressed on described loudspeaker again, just can more described loudspeaker be fixed on described base.
And what adopt due to loudspeaker fixture of the present utility model is that fastener fixing structure is fixed loudspeaker, make to operate very convenient laborsavingly, also loudspeaker securely can be fixed on described base simultaneously.
Preferably, described two compression pin are all affixed with described fixing column.
Preferably, described two buckle pin are symmetricly set in the both sides of the center line of described fixing column.
Preferably, each described compression pin and edge all are greater than a threshold value perpendicular to the angle between applied pressure on the direction of the upper surface of described loudspeaker.
Because described two compression pin may can produce slip because of the foozle between base and loudspeaker in the process of practical set, the angle that therefore must meet between described compression pin and pressing-in force is greater than arctan(b) (Arctan of b), static friction coefficient between the upper surface that wherein b is described compression pin and described loudspeaker, and in practice process, the value of static friction coefficient is generally 0.07, therefore, can get described threshold value is 5 degree, thereby just can guarantee can not produce slip.
Preferably, described threshold value is 5 degree.
Positive progressive effect of the present utility model is: the utility model adopts fastener fixing structure to be fixed loudspeaker, makes to operate very convenient laborsavingly, also loudspeaker securely can be fixed on base simultaneously.
The accompanying drawing explanation
The structural drawing of the loudspeaker fixture that Fig. 1 is a preferred embodiment of the present utility model.
The schematic diagram of the loudspeaker fixture assembling loudspeaker that Fig. 2 is a preferred embodiment of the present utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, two compression pin 2 that described loudspeaker fixture comprises a bayonet unit 1 and is symmetricly set in described bayonet unit 1 both sides, described bayonet unit 1 comprises two buckle pin 11 and a fixing column 12, described two buckle pin 11 are fixedly connected with described fixing column 12 by the supporting post 13 of a coupling respectively, and described two buckle pin 11 are symmetricly set in the both sides of the center line of described fixing column.Like this, each described buckle pin 11 just can form a groove with supporting post 13 and the described fixing column 12 of coupling.
Described two compression pin 2 all are fixedly connected with described fixing column 12, and like this, described loudspeaker fixture has just formed an integrated structure.
As shown in Figure 2, utilize described loudspeaker fixture just can be assembled and be fixed on a base 4 loudspeaker 3.
The spacing of the groove wherein, formed by each described buckle pin 11 and the supporting post 13 mated and described fixing column 12 all is set to just can hold described loudspeaker 3 and described base 4.Like this, just can be so that when the described loudspeaker 3 of assembling, the lower surface of described fixing column 12 can tightly be pressed on the upper surface of described loudspeaker 3, and the upper surface of described buckle pin 11 can be held in the lower surface of described base 4, thereby just described loudspeaker 3 is fastened on described base 4.Compress by described two the upper surface that pin 2 tightly is pressed on described loudspeaker 3 again, just can more described loudspeaker 3 be fixed on described base 4.
And each described compression pin 2 and all be greater than a threshold value perpendicular to the angle between the pressing-in force on the direction of the upper surface of described loudspeaker 3.
Because described two compression pin 2 may can produce slip because of the foozle between base 4 and loudspeaker 3 in the process of practical set, the angle that therefore must meet between described compression pin 2 and pressing-in force is greater than arctan(b), static friction coefficient between the upper surface that wherein b is described compression pin 2 and described loudspeaker 3, and in practice process, the value of static friction coefficient is generally 0.07, therefore, can get described threshold value is 5 degree, thereby just can guarantee can not produce slip.
In specific implementation process of the present utility model, each component are in actual manufacture process, there is error in capital, height error between the upper surface of the lower surface of described loudspeaker 3 and described base 4 is approximately 0.02mm, and the height error that the material thickness of described base 4 is added punching burr is less than 0.02mm.
And deformation can occur described two compression pin 2 in the process pressed down, therefore, in actual mechanical process, need to be controlled being applied to described two pressure that compress on pin 2, in order to avoid 2 deformation of described two compression pin are excessive.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art, under the prerequisite that does not deviate from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these changes and modification all fall into protection domain of the present utility model.
