Abstract
The utility model discloses an electronic product plastic component screw column structure, which comprises a component body, a screw column which is protuberant on the surface of the component body, screw holes are arranged in the middle of the screw column, the bottom surface of the screw holes is lower than the surface of the component body, and a circle ring groove is arranged on the surface of the peripheral component body at the root of the screw column. The electronic product plastic component screw column structure reduces local accumulation of root position materials of the screw column, enables the plastic component to be cooling and homogeneous, uneasy to shrink water and deform during the injection molding process.
Description
[technical field]
The utility model relates to electronic product plastic cement member, especially the screw columniation structure on the electronic product plastic cement member.
[background technique]
Mobile phone, camera, television set, electronic products such as computer all adopt electronic product plastic cement member screw columniation structure usually, in order to connect each other or to connect with other component, need the screw post of prefabricated hollow usually on these plastic cement members.When molding and forming, the plastic cement member is more because of material at the position of screw post root, is later than other position cooled and solidified, causes local contraction easily.And the design of general screw post is concentrated and the fracture of generation screw post for fear of Root Stress, the root of screw post of being everlasting again adds fillet, so more make screw post root part thick partially, material is piled up, cause mobile phone moulding appearance to shrink, not only image appearance is relatively poor, and causes the plastic cement member this position local deformation easily.
[summary of the invention]
The technical problems to be solved in the utility model provides the electronic product plastic cement member screw columniation structure of a kind of difficult shrink, distortion.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of electronic product plastic cement member screw columniation structure, comprise member bodies, the screw post of on the member bodies surface, giving prominence to, in the middle of the described screw post screw hole is arranged, the bottom surface of described screw hole is lower than the surface of member bodies, and a circle annular groove is arranged on the surface of screw post root peripheral members body.
Above-described electronic product plastic cement member screw columniation structure, the perpendicular distance on the bottom surface of described screw hole and member bodies surface is preferably 0.4 to 0.6 of member bodies wall thickness; The perpendicular distance on the bottom surface of described annular groove and member bodies surface is preferably 0.2 to 0.4 of member bodies wall thickness.
Above-described electronic product plastic cement member screw columniation structure, the periphery of described screw post preferably has 3 or 4 stiffening ribs to connect with the member body.
The utility model is lower than the surface of member bodies by the bottom surface that makes screw hole, on the surface of screw post root peripheral members body, increase the measure of a circle annular groove, reduced the local accumulation of screw post root part material, the plastic cement member is cooled off in injection moulding process evenly, be difficult for shrinking, being out of shape.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional view of prior art plastic cement member screw columniation structure.
Fig. 2 is the utility model electronic product plastic cement member screw columniation structure embodiment's a plan view.
Fig. 3 is that A among Fig. 2 is to view.
[embodiment]
In prior art plastic cement member screw columniation structure shown in Figure 1, comprise member bodies 1, screw post 2 has screw hole 3 in the middle of the screw post.Because the degree of depth of screw hole 3 is more shallow, and the root of screw post 2 has fillet R, so have more material to pile up at the I position, it is slower to dispel the heat, be later than other position cooled and solidified, other position cooled and solidified can obtain replenishing of I position liquid material when shrinking, and can not shrink.By the time after other position cooled and solidified, the material at I position is cooled and solidified, produce material contracts when the material cooled at I position is solidified and can not get replenishing of liquid material, will produce the shrink phenomenon on this surface, position, not only image appearance is relatively poor, and causes the plastic cement member this position local deformation easily.
Among the utility model electronic product plastic cement member screw columniation structure embodiment 1 shown in Figure 2, comprise member bodies 1, the screw post of giving prominence on the member bodies surface 2 has screw hole 3 in the middle of the screw post.Compare with prior art, the degree of depth of present embodiment screw hole 3 is darker, and the bottom surface of screw hole 3 is lower than the surperficial a of member bodies, and the perpendicular distance of the bottom surface of screw hole and member bodies surface a is 0.5 δ (δ is the member bodies wall thickness).One circle annular groove 4 is arranged on the surface of screw post root peripheral members body, and the perpendicular distance of the bottom surface of annular groove 4 and member bodies surface a is 0.3 δ.In order to prevent to deepen because of the degree of depth of screw hole 3, the weakening of 4 pairs of screw posts of screw post root periphery annular groove root intensity, present embodiment is provided with 4 stiffening ribs in the periphery of screw post 2 and connects with the member body.
The utility model is lower than the surface of member bodies by the bottom surface that makes screw hole, on the surface of screw post root peripheral members body, increase the measure of a circle annular groove, reduced the local accumulation of screw post root part material, plastic cement member each several part in injection moulding process is cooled off simultaneously, solidify simultaneously, after coagulation, generation of defects such as surface shrink, the distortion of screw post have been prevented to cool off behind the screw post root position.
Claims (3)
1. electronic product plastic cement member screw columniation structure, comprise member bodies, the screw post of on the member bodies surface, giving prominence to, screw hole is arranged in the middle of the described screw post, it is characterized in that, the bottom surface of described screw hole is lower than the surface of member bodies, and a circle annular groove is arranged on the surface of screw post root peripheral members body.
2. electronic product plastic cement member screw columniation structure according to claim 1 is characterized in that the perpendicular distance on the bottom surface of described screw hole and member bodies surface is 0.4 to 0.6 of a member bodies wall thickness; The perpendicular distance on the bottom surface of described annular groove and member bodies surface is 0.2 to 0.4 of a member bodies wall thickness.
3. electronic product plastic cement member screw columniation structure according to claim 1 is characterized in that the periphery of described screw post has 3 or 4 stiffening ribs to connect with the member body.
