The embodiment provides a watch screen dismounting mechanism. As shown in fig. 1 and 2, the watch screen dismounting mechanism includes a fixing base 1 and a dismounting assembly 2. The fixing seat 1 includes a base 11 and a supporting member 12 disposed above the base 11, and the base 11 and the supporting member 12 enclose a containing cavity for containing the watch. The dismounting assembly 2 comprises a dismounting member 21, a connecting rod 22 and a lifting member 23, the dismounting member 21 is arranged in the accommodating cavity, the connecting rod 22 is arranged in the accommodating cavity in a sliding mode and penetrates through the support member 12, one end of the connecting rod extends into the accommodating cavity and is fixedly connected with the dismounting member 21, the other end of the connecting rod is rotatably connected with the lifting member 23 outside the accommodating cavity, the lifting member 23 abuts against the support member 12, and when the lifting member 23 rotates, the connecting rod 22 can be driven to slide relative to the support member 12.

An operator can adjust the distance between the dismounting part 21 and the base 11 by rotating the lifting part 23, and when the dismounting part 21 grabs the screen, the operator rotates the lifting part 23 to enable the connecting rod 22 and the dismounting part 21 to move upwards so as to separate the screen from the panel shell. When the operator needs to bond the screen and the face shell, the lifting piece 23 can be rotated and the dismounting piece 21 is driven to move downwards to press the screen against the face shell and maintain the pressure, so that the bonding strength is ensured.

This wrist-watch screen dismouting mechanism can separate screen and face-piece through dismouting piece 21 to utilize dismouting piece 21 to carry out the pressurize to screen and face-piece when the installation, prevent to cause the damage and guarantee sufficient joint strength to the wrist-watch screen.

Preferably, the attachment/detachment means 21 is a suction cup. When the screen and the face shell need to be separated, the suction disc can adsorb the screen and move upwards under the driving of the connecting rod 22, so that the screen and the face shell are separated. Because the contact area between the suction disc and the screen is large, the force for lifting the screen by the suction disc is uniformly applied to the screen, so that when the screen is separated from the panel shell, the adhesive force can not be applied to the local part of the screen, and the screen is protected from being damaged. When the screen is installed and pressure is maintained on the screen, the sucker can buffer the pressure maintaining force by means of the elasticity of the sucker, and the screen is prevented from being damaged by the pressure maintaining force.

It will be appreciated that the release member 21 can also be divided into a release member and a retaining member, and the release member can be replaced by an operator according to actual needs. Wherein the detachable member needs to be able to lift the screen, such as a suction cup or a structure provided with a pressure sensitive adhesive. The pressure maintaining piece needs to be capable of buffering pressure maintaining force, and can be made of materials with certain elasticity, such as rubber.

Preferably, the lifting member 23 has a first supporting surface 231 and a second supporting surface 232 arranged at an included angle, and a distance between the rotating shaft 25 between the connecting rod 22 and the lifting member 23 and the first supporting surface 231 is smaller than a distance between the rotating shaft 25 and the second supporting surface 232.

When the pull-up member 23 abuts the support member 12 via the first support surface 231, the pull-up member 23 is in the first position. When the pull-up member 23 abuts the abutment member 12 via the second support surface 232, the pull-up member 23 is in the second position.

When the operator rotates the lifting piece 23 to switch the lifting piece 23 from the first position to the second position, the connecting rod 22 moves upward, and the screen and the face shell can be separated. Conversely, when the operator rotates the lifting piece 23 to switch from the second position to the first position, the connecting rod 22 moves downward, and the operator can apply pressure to the screen through the detachable piece 21 to maintain the pressure.

Further, the first supporting surface 231 and the second supporting surface 232 are transited by an arc surface 233. The arc surface 233 can greatly reduce the resistance of the operator to rotate the lifting member 23 and make the movement of the connecting rod 22 smoother and more stable.

Preferably, the knockdown assembly 2 further includes a handle 24, the handle 24 being connected to the pull-up member 23. The operator rotates the lifting piece 23 through the handle 24, and the lever principle is utilized, so that the working strength of the operator is greatly reduced, and the pulling force of the dismounting piece 21 on the screen can be greatly increased when the screen and the face shell are separated.

The operating personnel utilizes this dismouting mechanism to need the manual work to provide pressure when carrying out the pressurize to screen and face-piece, both extravagant manpower, again easily because of too big crushing screen of pressure. As shown in fig. 3 and 4, to solve this problem, the detaching mechanism further includes an elastic member 3, the elastic member 3 is sleeved on the connecting rod 22, and both ends of the elastic member 3 abut against the detaching unit 21 and the supporting member 12, respectively. Utilize elastic component 3 to provide the pressurize force, can make the pressurize power increase gradually, and operating personnel can select suitable elastic component according to the pressurize force of screen actual need, greatly reduced the cracked risk of screen.

Further, a guide groove 121 is concavely provided on one side of the supporting member 12 close to the detachable member 21, and one end of the elastic member 3 extends into the guide groove 121 and abuts against the groove bottom of the guide groove 121. The guide way 121 can be spacing to the flexible direction of elastic component 3, makes elastic component 3 only can stretch out and draw back along the axial, and the skew takes place when preventing elastic component 3 from stretching out and drawing back and leads to the card to die, has reduced the fault rate.

Preferably, the dismounting mechanism further comprises a sliding bearing 4, the sliding bearing 4 is sleeved on the connecting rod 22 and is in sliding fit with the connecting rod 22, and the sliding bearing 4 is fixedly connected with the supporting member 12. On the one hand, the sliding bearing 4 can guide the connecting rod 22 and prevent the connecting rod 22 from deviating from the axial direction and colliding with or rubbing against the support 12 when moving, thereby generating abnormal noise. On the other hand, the sliding bearing 4 can greatly reduce the resistance of the connecting rod 22 during movement, so that the operator can more easily rotate the pulling piece 23, and the working strength is reduced.

To fix the sliding bearing 4, the dismounting mechanism further comprises a locking screw, the side wall of the support 12 is provided with a threaded hole 122, the locking screw is in threaded connection with the threaded hole 122 and can abut against the sliding bearing 4 when being screwed into the threaded hole 122.

Preferably, the base 11 includes a bottom plate 111 and a U-shaped enclosure 112 fixed to the bottom plate 111, the support member 12 is connected to the U-shaped enclosure 112, and an opening of the U-shaped enclosure 112 forms a pick-and-place opening of the receiving cavity. Since the pressure holding of the screen is easy to make the base 11 and the support 12 bear a large force for a long time, the structural design of the base 11 and the support 12 needs to consider certain strength. The U-shaped enclosure 112 can improve the connection area between the base 11 and the support member 12 to the maximum extent on the premise of allowing the watch to enter the accommodating cavity, thereby improving the strength and prolonging the service life.

It can be understood that the back of most watches is not the pure flat structure, in order to guarantee that the watch is in steady state when carrying out the pressurize to the watch, set up the hole 113 of dodging that communicates in the holding chamber on the bottom plate 111. Dodge hole 113 can dodge the protruding structure at the back of the watch, thereby ensuring that the upper surface of the watch screen is in a horizontal and stable state.
