Description

A kind of variable tension and bales catch rubber band cell-phone cover

Technical field

Cell-phone cover technical field is the utility model is related to, variable tension mechanism and automatic fastening machine are provided with more particularly to one kind The rubber band cell-phone cover of structure.

Background technology

With the advance of information age, mobile phone turns into the inseparable partner of people, but in some cases can not be by hand Machine is carried with, such as during motion, when taking a walk etc., especially the clothes in summer is nice and cool to pursue, often without pocket, not side Just band mobile phone.On the other hand, as the quick popularization of smart mobile phone, the screen of mobile phone also tend to large-size screen monitors, therefore, occurred on the market There is shatter-resistant mobile phone protective cover, for convenience of using, be designed with finger ring and buckle to aid in holding adept machine.But being buckled by finger ring needs finger Intert into and caught on by finger, particularly when hand-held mobile phone deploys vertically downward naturally, mobile phone still can drop.It is right in addition It is very inconvenient to be buckled in the small use finger ring of palm, and can only be used cooperatively with palm, finger, there is certain limitation.Therefore, People are badly in need of one kind and not affected the appearance comfortably, and liberation both hands can carry with the device of mobile phone.

Utility model content

In order to solve the above problems, the utility model provide it is a kind of by rubber band by mobile phone be fixed on palm, the back of the hand, On finger, wrist or arm, and it is designed with the rubber band cell-phone cover of variable tension mechanism.

Technical scheme is used by the utility model：A kind of variable tension and bales catch rubber band cell-phone cover, its feature It is：It includes case body, tension force modification mechanism and bales catch mechanism located at case body back, the cell-phone cover sheet For body according to different mobile phone model injection moldings, tension force modification mechanism includes four be respectively arranged on case body back four Angle position；The bales catch mechanism is in the middle part of the long side at case body back；The tension force modification mechanism is a groove type bottom Shell, groove type drain pan are provided with a lever arm plate, and lever arm plate is with respect to one end in the middle part of case body and groove type drain pan axle Connection, axle is provided with a return spring, and by axle and return spring, lever arm plate is connected with groove type drain pan hinge-type, activity Arm plate is provided with connecting hole, by being connected with rubber band on connecting hole lever arm plate；The bales catch mechanism includes one and is provided with cunning The interior bottom that sliding groove is fixed on provided with back-moving spring, one end of back-moving spring of base, base of dynamic groove, the other end are connected with cunning Block, the upper end of base are provided with opening, and sliding block releases the front end with base by sliding groove, and sliding block bottom and middle part are equipped with connection Shaft end, the upper end of sliding block are provided with " y " type articulated end and are used to mount rubber band.

Rubber band described further located at case body back, connected by the lever arm plate of tension force modification mechanism, Two parallel rubber bands of long side can be connected into, or connect into cross one another " X " type rubber band.

The beneficial effects of the utility model are：By the implementation of the technical program, in cell-phone cover back designs tension force modification Mechanism and bales catch mechanism and rubber band, due to the elasticity of rubber band, the mobile phone of the supporting cell-phone cover can be placed on finger or Used on palm or arm, and the elasticity of rubber band can be relied on, mobile phone can tightly be enclosed on and use on hand, finger and palm It can completely open to have an effect and mobile phone is gripped, mobile phone is not fallen out, and liberates both hands, is avoided and is used hand for a long time yet Machine causes finger-joint, palm muscle rigidity.In addition, tension force modification mechanism, rubber band is drawn by more relatively large power, four The lever arm plate of the tension force modification mechanism of angle position is dug upwards, and rubber band both ends are jacked up to come, so as to the rubber band connected Power changes, it is easier to by cell-phone cover in wrist or arm.And bales catch mechanism, when having used mobile phone, finger abjection rubber Muscle, " y " the type articulated end being manually articulated in rubber band on sliding block, when acting on next time, sliding block is pushed up with finger, Connection shaft end in the middle part of sliding block slides out to sliding groove, due to the pulling force of rubber band, automatically digs sliding block upwards, while pass through cunning Rubber band is ejected certain altitude by the support of block, and in certain height, rubber band can deviate from " y " type articulated end automatically, make rubber Rubber band bales catch is so easy to rubber band to be buckled on palm, use is more flexible on finger.
