Abstract
It can reinforce drawing the mobile phone center of plastic structure the utility model relates to one kind, it includes the center ontology in rectangle, offer at least one cylindric through-hole for running through center ontology upper and lower surface respectively at the four corners position of center ontology, and the rectangular notch portion of connection center body interior space and cylindric through-hole is offered to the inner wall of center ontology along cylindric through-hole, and the width in rectangular notch portion is less than the diameter of cylindric through-hole；In on the inner wall of center ontology, the two sides position in each rectangular notch portion be also separately formed inside several boss outstanding, the thickness direction along boss forms longitudinal hole or arc notch portion on each boss.The utility model mobile phone center is using the above structure, when being molded after mobile phone center and middle board group set position, plastic material enters cylindric through-hole and the rectangular notch portion of mobile phone center, and it coats in the convex block of center inner wall, the through-hole for being filled into convex block or arc notch portion, to form firm drawing plastic structure.
Description
Technical field:
The utility model relates to mobile phone components product technical fields, and refering in particular to one kind can reinforce drawing in the mobile phone of plastic structure
Frame.
Background technique:
In traditional mobile phone center plate generally directly adopt aluminium alloy plate directly pass through the techniques such as hollow out, cutting production it is whole
The center of body and middle plate, this processing method are processed using CNC, and the process is more complicated, and difficulty of processing is big, at high cost, and material
Utilization rate is lower.The mode assembled again after die cast respectively is used for this purpose, also having in the industry to process center with middle plate to reduce
Cost.And this mode is to center that the hardened conjunction intensity requirement in is higher, majority is using connecting by the way of threaded connection, process
Also relative complex, operation is also not convenient, and production efficiency also accordingly declines.In addition, some products can be in middle board ends and center two
End further increases bond strength by injection moulding plastic material, however only center inner wall surface connects with plastic material after being molded
Phenomena such as touching, being easy to appear degumming after injection molding causes to draw plastic structure loosely, influences product quality and service life.
Utility model content:
The purpose of the utility model is to overcome the shortcomings of existing equipment, provide a kind of mobile phone that can reinforce drawing plastic structure
Center.
The technical solution adopted in the utility model is: one kind can reinforce drawing the mobile phone center of plastic structure comprising be in rectangle
Center ontology, offered respectively at the four corners position of center ontology at least one run through center ontology upper and lower surface cylinder
Shape through-hole, and connection center body interior space and cylindric through-hole are offered to the inner wall of center ontology along cylindric through-hole
Rectangular notch portion, and the width in rectangular notch portion is less than the diameter of cylindric through-hole；In on the inner wall of center ontology, each rectangle
The two sides position of notch section has also been separately formed inside several boss outstanding, along boss thickness direction on each boss at
Type has longitudinal hole or arc notch portion.
Arc interconnecting piece is also formed between two sides convex block outer end at two of them rectangular notch portion.
The utility model mobile phone center using the above structure, when being molded after mobile phone center and middle board group set position, plastic cement
Material enters cylindric through-hole and the rectangular notch portion of mobile phone center, and coats the convex block of center inner wall, is filled into convex block
Through-hole or arc notch portion in, to form firm drawing plastic structure, make center and middle plate connection and other zero
The fixation of part is more firm, while the crash resistance of whole mobile phone frame also can be improved, and extends product service life.
Detailed description of the invention:
Fig. 1 is the schematic perspective view of the utility model center；
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment:
The present invention will be further described with attached drawing combined with specific embodiments below.
As shown in Figure 1 and Figure 2, described in the utility model is a kind of mobile phone center that can reinforce drawing plastic structure comprising is in
The center ontology 1 of rectangle offers at least one at the four corners position (or close to four corners position) of center ontology 1 respectively and runs through
The cylindric through-hole 11 of 1 upper and lower surface of center ontology, and offered in connection along cylindric through-hole 11 to the inner wall of center ontology 1
The rectangular notch portion 12 of 1 inner space of frame ontology and cylindric through-hole 11, and the width in rectangular notch portion 12 is less than cylindric lead to
The diameter in hole 11, in injection molding, plastic material injects cylindric through-hole 11 and rectangular notch portion 12, plastic material curing molding
The fastening type structure that inner end is big and outer end is small is formed afterwards, to play the effect for reinforcing drawing plastic structure；In the inner wall of center ontology 1
The two sides position in upper, each rectangular notch portion 12 has also been separately formed inside several boss 13 outstanding, along the thickness of boss 13
Direction forms longitudinal hole 131 or arc notch portion 132 on each boss 13.Boss 13 is different according to the length of protrusion,
Longitudinal hole 131 or arc notch portion 132 are formed when carrying out longitudinal hollow out, can increase plastic cement using arc notch portion 132
With 1 contact area of center ontology, more stable drawing plastic structure is formed using injection molding cladding convex block 13 in longitudinal hole 132.
Arc interconnecting piece 133 is also formed between 13 outer end of two sides convex block at two of them rectangular notch portion 12；I.e.
A " u "-shaped interconnecting piece is formed in the outer end in rectangular notch portion 12, makes to form enclosed construction inside rectangular notch portion 12, be molded
" u "-shaped interconnecting piece is enveloped using inside and outside afterwards, is further formed stable drawing plastic structure.
The utility model mobile phone center using the above structure, when being molded after mobile phone center and middle board group set position, plastic cement
Material enters cylindric through-hole and the rectangular notch portion of mobile phone center, and coats the convex block of center inner wall, is filled into convex block
Through-hole or arc notch portion in, to form firm drawing plastic structure, make center and middle plate connection and other zero
The fixation of part is more firm, while the crash resistance of whole mobile phone frame also can be improved, and extends product service life.
