Abstract
The invention discloses an injection molding nut, which comprises a nut main body, wherein the top of the nut main body is provided with an upper injection molding block, and the bottom of the nut main body is provided with a lower injection molding block; the outer surfaces of the upper injection molding block and the lower injection molding block are provided with oblique teeth respectively; a threaded hole is formed in the middle of the nut main body; a groove is formed in the middle of the upper injection molding block and the lower injection molding block respectively; the upper injection molding block and the lower injection molding block of the injection molding nut are formed in two circuit boards to be connected by injection molding respectively; and then the circuit boards are fixed by screwing a screw into the threaded hole in the middle of the nut main body. Since the outer surfaces of the upper injection molding block and the lower injection molding block are provided with the oblique teeth respectively, and after the injection molding nut is formed into the circuit boards by injection molding, plastic pulp is cooled and solidified in a gap of the oblique teeth to firmly clamp the injection molding nut in the circuit boards; and after the injection molding nut is formed into the circuit board by injection molding, the upper injection molding block and the lower injection molding block are wrapped by the plastic pulp on the two circuit boards respectively to form a plastic film in the grooves respectively; and the injection molding nut is further fixedly arranged in the circuit boards, so that the phenomenon of stripping is not easily caused, and the durability is high.
Description
Technical field
The present invention relates to mobile phone part field, especially relate to a kind of injection moulding nut.
Background technique
Present mobile phone on the market is multifarious, development along with mobile phone, the component of interior of mobile phone are also towards the aspect such as meticulous, firm, durable development, because dwindling of mobile phone overall volume, inner components is also more compact, and used nut generally all uses the injection moulding nut, and general injection moulding nut smooth surface, shake and excessively easily come off, serviceability is not strong.
Summary of the invention
In order to overcome defects, the invention provides a kind of injection moulding nut.
The present invention solves the technological scheme that its technical problem takes: a kind of injection moulding nut, comprise nut main body, described nut main body top is provided with the injection moulding piece, described nut main body bottom is provided with lower injection moulding piece, described upper injection moulding piece and lower injection moulding piece outer surface respectively are provided with helical teeth, be provided with tapped hole in the middle of the described nut main body, be provided with groove in the middle of described upper injection moulding piece and the lower injection moulding piece.
The invention has the beneficial effects as follows: upper injection moulding piece and the lower injection moulding piece of injection moulding nut respectively are injected into respectively in two circuit boards of required connection, then screw being screwed in the middle tapped hole of nut main body fixes circuit board, because upper injection moulding piece and lower injection moulding piece outer surface all are provided with helical teeth, when the injection moulding nut is injection molding behind circuit board, mould slurry cooled and solidified in the helical teeth gap, firmly be stuck in the injection moulding nut in the circuit board, be provided with groove in the middle of upper injection moulding piece and the lower injection moulding piece, when the injection moulding nut is injection molding behind circuit board, the slurry of moulding on two circuit boards superscribes respectively injection moulding piece and lower injection moulding piece, form one deck plastic film at groove, further be fixed on the injection moulding nut in the circuit board, make more firm being injection-moulded in the circuit board of injection moulding nut, be not easy to occur obscission, serviceability is stronger.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan view of the present invention;
Among the figure: 1, nut main body 2, upper injection moulding piece 3, lower injection moulding piece 4, helical teeth 5, tapped hole 6, groove.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of injection moulding nut shown in Fig. 1-2, comprise nut main body 1, described nut main body 1 top is provided with injection moulding piece 2, described nut main body 2 bottoms are provided with lower injection moulding piece 3, described upper injection moulding piece 2 respectively is provided with helical teeth 4 with lower injection moulding piece 3 outer surfaces, be provided with tapped hole 5 in the middle of the described nut main body 1, described upper injection moulding piece 2 and the lower injection moulding piece 3 middle grooves 6 that are provided with.
After adopting said structure, be characterized in: the upper injection moulding piece 2 of injection moulding nut respectively is injected into respectively in two circuit boards of required connection with lower injection moulding piece 3, then the tapped hole 5 that screw is screwed in the middle of the nut main body 1 is fixed circuit board, because upper injection moulding piece 2 all is provided with helical teeth 4 with lower injection moulding piece 3 outer surfaces, when the injection moulding nut is injection molding behind circuit board, mould slurry cooled and solidified in helical teeth 4 gaps, firmly be stuck in the injection moulding nut in the circuit board, upper injection moulding piece 2 and the lower injection moulding piece 3 middle grooves 6 that are provided with, when the injection moulding nut is injection molding behind circuit board, the slurry of moulding on two circuit boards superscribes respectively injection moulding piece 2 and lower injection moulding piece 3, form one deck plastic film at groove 5 places, the injection moulding nut further is fixed in the circuit board, make more firm being injection-moulded in the circuit board of injection moulding nut, be not easy to occur obscission, serviceability is stronger.
