Etc. information.The protecgulum 20 is transferred with the shell 10 by the circle mouth 30.Specifically, the first plane of the circle mouth 30
301 are equipped with groove 31.The protecgulum 20 is fixed in the groove 31.The circle mouth 30 is second flat away from the groove 31
Face 302 is bonded with the shell 10 and realizes being connected for the protecgulum 20 and the shell 10.About the protecgulum 20 with it is described
The connection of groove 31, the bottom surface 21 of the protecgulum 20 is bonded to each other with the bottom wall 311 of the groove 31, and the side of the groove 31
Wall 312 is enclosed set on the periphery of the protecgulum 20.As a result, the lateral surface 22 of the protecgulum 20, the bottom wall 311 of the groove 31 and
The madial wall 312 of the groove 31 encloses jointly sets out a receiving space 50.It should be understood that since the receiving space 50 is
Made of being surrounded by three faces, so the side of the receiving space 50 is opening 51.In herein described wrist-watch 100, institute
It states opening 51 and deviates from the shell 10.Another describing mode uses in user and faces herein described hand described in angular observation
On the first direction 001 of table 100,51 direction of the opening of the receiving space 50 is separate described along the first direction 001
Shell 10.
Referring to Fig. 3, the colloid 40 is contained in the receiving space 50.Specifically, being squeezed into the protecgulum 20 described
Before groove 31, the colloid 40 is positioned in the receiving space 50.It is hollow in the colloid 40, the colloid 40 is hollow
Shape and the shape of the protecgulum 20 match, and be between the hollow profile of the colloid 40 and the shape of the protecgulum 20
Interference fit.When the protecgulum 20 is squeezed into the groove 31, the lateral surface 22 of the protecgulum 20 squeezes the colloid 40, makes
The periphery of the colloid 40 is resisted against the madial wall 312 of the groove 31, the bottom of the colloid 40 is held in described
The bottom wall 311 of groove 31.After the protecgulum 20 is completely into the groove 31, the colloid 40 generates larger elasticity
Deformation, is filled within the receiving space 50.Due to the flexible deformation of the colloid 40, increase the colloid 40 with it is described
Pressure between lateral surface 22 and the colloid 40 and the madial wall 312, to increase the colloid 40 with it is described before
Frictional force between circle mouth 30 described in lid 20 and the colloid 40.The protecgulum 20 is able to realize with the circle mouth 30 as a result,
It is fixedly connected.
In herein described wrist-watch 100, the receiving space 50 includes opposite open side 501 and bottom side 502.It can be with
Understand, the open side 501 is for the lateral surface 22 with the madial wall 312 close to first plane, 301 side phase
To the opening of formation, the bottom side 502 is the lateral surface 22 and the madial wall 312 close to second plane 302 1
The opposite opening formed in side.Width dimensions at the open side 501 are less than the width dimensions at the bottom side 502.It fills out as a result,
It fills in the colloid 40 in the receiving space 50, is open on 51 direction, is formed towards described along the first direction 001
Glue width at the open side 501 is less than the effect far from the glue width at the open side 502.When the colloid
40 because of aging or the reason of expand with heat and contract with cold, and the pressure between the madial wall 312 reduces, and frictional force is caused accordingly to reduce
And towards it is described opening 51 at slide when, because of relatively volume bigger of the colloid 40 far from 501 1 side of the open side, hinder
Sliding action of the colloid 40 relative to the circle mouth 30 so that the colloid 40 is able to continue to stay in the receiving space
Within 50.Correspondingly, the protecgulum 20 is also able to continue to generate frictional force, the protecgulum 20 and the circle mouth with the colloid 40
Relative displacement between 30 is able to be controlled.Therefore, herein described wrist-watch 100 is because of the broad-ruler at the open side 501
The very little width dimensions less than at the bottom side 502, and obtain stronger connection between the protecgulum 20 and the circle mouth 30
Effect improves the reliability and service life of the wrist-watch 100.
For the lateral surface 22 of the protecgulum 20, it is typically parallel to the first direction 001.This is because before described
The hardness of lid 20 is higher, and the materials such as generally use sapphire, glass or crystal are made.Forming the higher lateral surface of precision
During 22, it usually needs the modes such as polishing could be completed to process.If it is even bent that the lateral surface 22 is designed as inclined-plane
If face, difficulty of processing can be greatly improved.Therefore, in the embodiment that the lateral surface 22 is parallel to the first direction 001,
Width dimensions at the open side 501 difference in size will occur with the width dimensions at the bottom side 502, cannot be described outer
The side of side 22 is realized, can only be realized by the madial wall 312.It is cut perpendicular to the arbitrary of first plane 301
On face, the receiving space 50 is trapezoidal, and the open side 501 and the bottom side 502 are trapezoidal two opposite parallel edges.It can
With understanding, the angle between two parallel edges and the lateral surface 22 is right angle.The madial wall 312 and the bottom as a result,
Angle between wall 311 needs to be arranged to acute angle, could realize that the width dimensions at the open side 501 are less than the bottom side
Width dimensions at 502.

Row control.If the inclination angle of angle is too small, that is, it is less than 85 °, along the direction of the first direction 001, the colloid 40 holds
The compression deformation difference for being also easy to produce rear and front end is excessive, causes the damage of the colloid 40 or part colloid empty in the receiving
Between occur in 50 larger displacement offsets unfavorable phenomenon.Entire standing of the colloid 40 in the receiving space 50 can be located
In unsure state, certain thrust being displaced outwardly along the first direction 001 will produce to the protecgulum 20, it is right instead
The setting of the colloid 40 produces negative effect.And when angle setting is in 85 °~89 °, the standing shape of the colloid 40
State is more stable, and the thrust on the first direction 001, energy are nearly free to the protecgulum 20 in the receiving space 50
It is enough that preferable fixing effect is harvested to the protecgulum 20.
In addition, the setting of 85 °~89 ° inclination angle ranges of the angle, under the premise of considering the deflection of the colloid 40,
It reference is also made to the factor of technology controlling and process wherein.It is common, the inclination angle be using the equipment such as numerically controlled lathe or numerically control grinder into
Driving cut or grinding and obtain.Because of the small volume of the circle mouth 30, the clamping face that can be provided in shape is opposite
It is less.If by the too small of the inclination angle range setting of the angle, being substantially improved for machining accuracy can be caused.Be aided with again clamping face compared with
The difficulty of processing of few feature, the circle mouth 30 can be substantially improved accordingly.And the angular range is ensureing the change of colloid 40
Under the premise of shape amount, processing cost can be suitably reduced so that scheme of the invention is unlikely to during large-scale application to described
The economy of wrist-watch 100 has much impact.
