This embodiment explains with utilizing stop gear to assist to install the vibrator in the cell-phone shell as the example, and the cell-phone shell is the installed part promptly.

The embodiment provides a limiting mechanism. As shown in fig. 1 and 2, the limiting mechanism includes a locking assembly 1, a turnover assembly 2 and a limiting assembly 3. The locking assembly 1 comprises a mounting table 11 and a locking piece 12 rotatably arranged on one side of the mounting table 11. The turnover assembly 2 includes a fixing base 21 and a cover plate 22, and the cover plate 22 can rotate relative to the fixing base 21. The limiting assembly 3 comprises a sliding part 31, the sliding part 31 is arranged on the cover plate 22 in a sliding mode, one end of the sliding part 31 is connected with a limiting part 32, the other end of the sliding part 31 is a locking end, and when the cover plate 22 rotates in place towards the direction of the installation table 11, the locking part 12 can be clamped with the locking end. The founding wall of cell-phone shell is located the one side that locating part 32 is close to apron 22, and locating part 32 is higher than the cell-phone shell and locating part 32 follows apron 22 and gets into the cell-phone shell from the cell-phone shell top.

The operating personnel places the cell-phone shell opening upwards, when rotating apron 22 towards mount table 11, locating part 32 is close to the cell-phone shell along with slider 31, and when locating part 32 got into the cell-phone shell, operating personnel moved slider 31 towards the direction of keeping away from locking piece 12 and made to have certain clearance between locating part 32 and the cell-phone shell and prevent the striking. When the limiting member 32 enters the mobile phone, the sliding member 31 is moved reversely to clamp the locking member 12 to the locking end. When the operator mounts the vibrator against the limiting member 32, the vibrator abuts against the limiting member 32, so that the sliding member 31 cannot slide relative to the cover plate 22. At this time, the operator can rotate the locking member 12 to release the clamping of the sliding member 31, so that the operator can directly drive the limiting member 32 to separate from the mobile phone shell through the rotating cover plate 22. This stop gear can avoid locating part 32 to take place to interfere and take place to interfere the condition emergence of interfering with the vibrator when shifting out the cell-phone shell with the cell-phone shell when getting into the cell-phone shell well.

Preferably, the limiting assembly 3 further includes a first elastic member 33, two ends of the first elastic member 33 abut against the cover plate 22 and the sliding member 31, respectively, and the locking end is locked with the locking member 12 by being driven by the first elastic member 33. The first elastic member 33 moves the slider 31 in the direction of the locking member 12, preventing the operator from shifting the mounting position due to the movement of the slider 31 during the mounting of the vibrator.

As shown in fig. 3 and 4, the sliding member 31 is provided with a limiting hole, the cover plate 22 is provided with a limiting screw, the limiting screw passes through the cover plate 22 and the limiting hole, two ends of the first elastic member 33 respectively abut against the limiting screw and the limiting hole, and the first elastic member 33 can drive the sliding member 31 to move relative to the cover plate 22, so that the sliding member 31 slides to the locking member 12. It is understood that the first elastic member 33 is a spring.

Wherein, the locking subassembly 1 still includes second elastic component 13, as shown in fig. 5, the both ends of second elastic component 13 respectively butt in mount table 11 and locking piece 12, and locking piece 12 locks with the locking end joint under the drive of second elastic component 13. Second elastic component 13 can drive locking piece 12 and rotate around the axis of rotation, prevents that locking piece 12 from rotating when joint locking end and leading to the locking failure, influences the degree of accuracy of installation.

Preferably, a buckle 121 is protruded from one side of the locking member 12, and the locking end can be clamped and locked between the buckle 121 and the mounting table 11. The distance between the buckle 121 and the mounting platform 11 is slightly larger than the thickness of the cover plate 22, so that the cover plate 22 cannot enter the gap between the buckle 121 and the mounting platform 11, and the cover plate 22 cannot be clamped and locked.

For preventing apron 22 from rocking between buckle 121 and mount table 11 and leading to influencing the installation of vibrator, fixing base 21 is provided with the third elastic component, and the third elastic component can drive apron 22 and rotate towards the direction of keeping away from mount table 11, and when apron 22 card goes into the clearance between buckle 121 and the mount table 11, the third elastic component can make apron 22 support tightly the remain stable with buckle 121.

Wherein, the upper surface of the buckle 121 is provided with a guiding surface, the guiding surface inclines downwards along the direction far away from the locking piece 12, when the cover plate 22 rotates towards the mounting table 11, the sliding piece 31 is far away from the buckle 121 under the guiding of the guiding surface, as shown in fig. 5. The arrangement of the guide surface enables the sliding member 31 to automatically move away from the buckle 121 to enable the limiting member 32 to avoid the mobile phone shell when the cover plate 22 rotates towards the mounting table 11, so that the operation step that an operator moves the sliding member 31 towards the direction away from the locking member 12 is replaced, and the workload of the operator is reduced.

It will be appreciated that the force required to rotate the locking member 12 against the elastic force of the second elastic member 13 is greater than the force required to rotate the sliding member 31 against the elastic force of the first elastic member 33. That is, when the sliding member 31 abuts against the catch 121, the locking member 12 will not rotate, and the sliding member 31 will move away from the locking member 12, which is convenient for the operator to operate. When the stopper 32 is to be removed from the inside of the handset case upon completion of the installation, the operator is required to rotate the locking piece 12 to unlock the sliding piece 31.

The sliding member 31 can be kept balanced and stable against the locking member 12 under the driving of the first elastic member 33, so that the application range of the limiting mechanism is small. To solve this problem, the position limiting assembly 3 further comprises an adjusting member 34, the adjusting member 34 is adjustably mounted on the sliding member 31 along the sliding direction of the sliding member 31, and the adjusting member 34 can adjust the position limiting position of the position limiting member 32 by abutting against the cover plate 22. An operator can adjust the relative position between the adjusting member 34 and the sliding member 31 according to the position where the limiting member 32 needs to stop, so that when the adjusting member 34 abuts against the cover plate 22 during the sliding of the sliding member 31 toward the locking member 12, the limiting member 32 is located at the position where the limiting member 32 needs to stop.

In order to ensure the position accuracy of the position limiting member 32, the cover plate 22 is provided with a guide hole 221, the mounting table 11 is provided with a guide post 111, and when the cover plate 22 is rotated to a proper position towards the mounting table 11, the guide post 111 is inserted into the guide hole 221.

The guide hole 221 is an oblong hole, the long axis direction of the oblong hole is perpendicular to the rotation axis direction of the cover plate 22, and the distance between two straight edges of the oblong hole is equal to the diameter of the guide column 111. The long round guide hole 221 can prevent interference with the guide post 111 when the cover plate 22 rotates, and after the guide post 111 is inserted into the guide hole 221, two straight edges of the long round hole can be positioned with the guide post 111, so that the position accuracy of the limiting piece 32 is ensured.

Preferably, the turnover assembly 2 further includes a driving member 23, and the driving member 23 is fixedly disposed on the cover plate 22. The provision of the drive 23 facilitates the operation of the cover 22 by an operator.

Further, the mount 11 is provided with a sensor 112, and the sensor 112 is capable of detecting whether the cover plate 22 is rotated in place toward the mount 11. The operator can determine whether the cover 22 is in place according to the sensing result of the sensor 112, and if the cover 22 is in place, the operator can mount the vibrator according to the position of the position-limiting member 32.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
