Abstract
A key positioning structure is used for positioning a key to a shell of an electronic device. The key comprises a press portion and a suspension arm extending from one end of the press portion, the suspension arm comprises a first positioning hole and a positioning column arranged at the tail end of the suspension arm, and the positioning column comprises a retaining portion which is protrudingly arranged on the surface of the positioning column. The shell is provided with a through hole and comprises a positioning block and a positioning pin extending from the inner surface of the shell, the positioning block is provided with a second positioning hole, and the positioning column is inserted into the second positioning hole to enable the retaining portion to penetrate through the second positioning hole. The key is rotated to enable the positioning pin to be contained in the first positioning hole of the suspension arm, one side of the press portion is contained in the through hole of the shell, and the retaining portion of the positioning column is retained at the bottom of the second positioning hole, so that the key is positioned on the shell. Using the key positioning structure can guarantee the key against damage and reduce key assembly cost.

The utility model content
In view of this, a kind of button location structure need be provided, can guarantee that button is not damaged, can reduce the cost of button assembling again.
Button location structure in the utility model execution mode is used for button is positioned the housing of electronic installation.Said button comprises press section and the cantilever that end extends from one of said press section, and said cantilever comprises first location hole and be located at the reference column of the end of said cantilever that said reference column comprises the stopper section on the surface that is based in said reference column.Said housing is provided with through hole, comprises alignment pin and the locating piece that extend on the surface within said housing, and said locating piece is provided with second location hole.Said reference column inserts said second location hole makes said stopper section pass said second location hole.Rotate said button; Make said alignment pin be contained in first location hole of said cantilever; One of said press section side is contained in the through hole of said housing, and the stopper section backstop of said reference column is in the bottom of said second location hole, thereby said button is positioned said housing.
Preferably; Said second location hole comprises location notch and the accepting hole that communicates with said location notch; Said location notch is passed in the stopper section of said reference column, and said reference column is contained in the said accepting hole, rotates said reference column and makes said stopper section backstop in the bottom of said accepting hole.
Preferably, be matched in clearance between said reference column and the said accepting hole.
Preferably, be matched in clearance between said alignment pin and said first location hole.
Compared to prior art, the button location structure that the utility model provides, manual operation just can realize the location of button, can avoid button to scald, assembling is simple, can save assembly cost.

Embodiment
Please be simultaneously with reference to Fig. 1 and Fig. 2, the button location structure 100 that the utility model provides is used for button 10 is positioned the housing 20 of electronic installation.One of button 10 side is located at outside the said housing 20 surface, and the trigger switch (not shown) on the opposite side circuit board interior with being installed in case of electronic device contacts, and pushes said button 10 to trigger the trigger switch on the said circuit board.
Please with reference to Fig. 3, button 10 comprises that press section 11 reaches the cantilever 12 of holding the row extension from one of said press section 11 level with both hands.Cantilever 12 comprise first location hole 121 and be located at said cantilever 12 end and with said cantilever 12 reference columns 122 connected vertically, said reference column 122 comprises the stopper section 123 on the surface that is based in said reference column 122.
Please be simultaneously with reference to Fig. 4, button 10 was installed in 20 last times of housing, second location hole 24 that the reference column 122 of button 10 inserts housings 20 makes the stopper section 123 of reference column 122 pass said second location hole 24.Rotating key 10; Make the alignment pin 22 of housing 20 be contained in first location hole 121 of cantilever 12; The press section 11 of button 10 is contained in the through hole 21 of housing 20; Stopper section 123 backstops of reference column 122 are in the bottom of said second location hole 24, the trigger switch (not shown) on housing 20 interior circuit boards thus the press section 11 of contact button 10 is positioned button 10 for housing 20.
In this execution mode, second location hole 24 of the locating piece 23 of housing 20 comprises location notch 241 and the accepting hole 242 that communicates with said location notch 241.During installation, said location notch 241 is passed in the stopper section 123 of the reference column 122 of button 10, and said reference column 122 is contained in the said accepting hole 242, rotates said reference column 122 and makes said stopper section 123 backstops in the bottom of said accepting hole 242, and is as shown in Figure 4.
In this execution mode, between the reference column 122 of button 10 and the accepting hole 242 of housing 20 and be matched in clearance between first location hole 121 of the alignment pin 22 of housing 20 and button 10 and be stuck to avoid button 10 with the rotation nargin of guaranteeing button 10.
100 need of the button location structure that the utility model provides are inserted into the reference column 122 of button 10 in second location hole 24 of locating piece 23 of housing 20; Rotate button 10 and can button 10 be positioned housing 20; Manual operation just can realize the location of button 10; Avoid button 10 to be scalded, can save assembly cost simultaneously.
