Description

Mobile terminal ring buckle

Technical field

[0001] The present invention relates to the field of mobile terminal bracket technologies, and in particular, to a mobile terminal ring buckle. The present invention is based on a Chinese utility model patent with the patent number CN201720134130.3 and the application date being February 14, 2017, the content of which is incorporated herein by reference.

Background technique

[0002] The existing mobile terminal finger ring includes a patch panel, a face cover and a ring member, the first side of the patch panel is provided with an adhesive layer, the ring member is hinged on the face cover, and the sticker panel faces away from the first a male engaging portion is disposed on the second side of the side, a female engaging portion is disposed on the back side of the cover, and the male engaging portion is a second annular protrusion on the outer peripheral surface of the applying plate, and the female engaging portion is a surface The engaging protrusion on the inner circumferential surface of the cover, and the elastic binding of the second annular protrusion and the second inner buckle protrusion are matched. An elastic plate is connected to the plate. The extended end of the elastic plate is connected with an elastic limiting protrusion. The surface cover is provided with a plurality of limiting holes, and the elastic limiting protrusion can selectively enter the limiting hole.

[0003] A problem with the existing mobile terminal finger ring buckle is that the rotational positioning between the face cover and the patch plate is achieved by the elastic limit protrusion being clamped into the limit hole. The conditions for the elastic limit protrusion to smoothly enter the limit hole include: a guide surface between the elastic limit protrusion and the limit hole, and a shallow depth of entry of the elastic limit protrusion relative to the limit hole. These conditions achieve the same positioning stability between the cover and the plate when the elastic limit protrusion is inserted into the limit hole; the same can only be achieved by the cooperation of the elastic limit protrusion and the limit hole. The relative positioning of some fixed angular positions with the slats makes the use of the buckles inconvenient. Therefore, it is necessary to improve the existing mobile terminal ring buckle.

Problem solution

Advantageous effects of the invention

Beneficial effect

[0016] After the surface cover of the ring fastener of the present invention is assembled and fitted with the patch panel, under the force of the metal spring, the first side of the annular matching protrusion on the panel abuts on the boss of the cover. There is a large friction between the cover and the plate; when the opposite cover and the plate are squeezed to make the two closer to the 吋, the slab is separated from the boss, and the ball is only metal shrapnel. The crown is abutted on the cover to produce a very small frictional force, and there is no contact between the cover and the plate without friction, and the rotation between the two is smooth. In the fixed state of normal use, the cover and the plate are fixed to each other. The user needs to adjust the angle of the cover and the ring. Only the face cover needs to be pressed down, so that the rotation can be easily adjusted and the buckle can be stabilized. Rotate the positioning and achieve full angular positioning between the two. [0017] The metal shrapnel is made of metal copper, and the copper shrapnel has better stability and elastic deformation capability, and meets the requirements for use of the finger ring of the mobile terminal.

[0018] Further, the pressure between the connecting portion of the ring member and the face cover forms a frictional force, so that the ring member can be fixed in an arbitrary rotation state with respect to the connecting portion.

[0019] In addition, after the shrapnel is mounted, the deformation of the copper sheet causes air compression in the sealed space formed between the depressed portion of the copper sheet and the contact surface, and the through hole prevents the formation of air compression, and the buckle is more stable. Mechanism state; Similarly, the through hole also facilitates the adhesion between the adhesive layer and the patch.

[0020] In addition, when the ring buckle is not used, the ring member can be placed outside the cover to form a storage state of the buckle, so that the buckle is more humanized.

[0021] In addition, the depth of the accommodating cavity of the present invention is less than the height of the slats to ensure that the ring buckle is adhered to the back of the mobile terminal through the double-sided film, and the cover does not contact the mobile terminal casing, thereby ensuring that the rotation of the cover is not correct to the mobile terminal. Causes wear and tear.

[0022] Moreover, when the ring member is turned over to achieve the storage state, the annular limiting protrusion can effectively prevent the ring member from colliding with the casing of the mobile phone, and protect the mobile terminal such as a mobile phone.
