Abstract
Disclosed is a joint support, applied to a component based device which is a corresponding combination of at least a first shell body and a second shell body with a containing space formed between the two shell bodies. The utility model comprises a support part and a joint part formed on the support part, wherein, the support part which has a first chamber whose wall is of homogeneous thickness is formed on the surface of the first shell body towards the containing space through a first forming die; the joint part is formed on the support part through a second forming die, with a second chamber with a homogenized wall communicated with the first chamber. The application of the utility model can improve the quality of the joint support, relatively avoiding the problem of non-uniform wall thickness caused by manufacturing joint support only by a single forming die with a longer size.
Description
Technical field
The utility model relates to a kind of joint pillar, more detailed it, relate to and a kind ofly be applied at least to form and between this first housing and this second housing, be formed with joint pillar in the modular device of an accommodation space by one first housing and the corresponding assembling of one second housing.
Background technology
Generally speaking, common joint pillar for example is applied to the joint assembling of the upper and lower enclosure of host computer.
As shown in Figure 1, it shows the side-looking diagrammatic cross-section of the joint pillar 1 of existing longer size, its be by the plastic parts forming materials on a upper casing 2, and, this joint pillar 1 has a hollow bulb 10, for one be arranged in lower casing (diagram) for example for spiro connecting element such as screw is spirally connected, thereby lower casing can firmly be bonded with each other with this upper casing 2.Wherein, this engages pillar 1 is frustum cone structure, and this upper casing 2 12 is gradually-reducing shape to the top certainly, and for example be formed by injection molding type for the mould of curved lever by one, and for this mould can be chosen after Shooting Technique smoothly, this hollow bulb 10 is a wedge structure, and top 12 to this upper casing 2 of this joint pillar 1 is gradually-reducing shape certainly.
But, the joint of the existing longer size of this kind props up in its forming process of major gene, only undertaken by single mould, so when injection mo(u)lding, need to use long mould, thereby can't accurately grasp the wall thickness uniformity coefficient after its moulding, therefore, the existing long joint pillar of this kind easily also causes the problem of wall unevenness, relatively easily cause this long joint pillar in forming process, to produce more serious shrink phenomenon, that is because of needing the long cooling and the time of curing by long joint pillar, so because volumetric contraction, the material at wall thickness place easily is drawn into, so that when solidifying, produce depression in the surface of long joint pillar at this easily, shrinkage cavity and quality defect such as sandwich; In addition, the joint pillar of this longer size, need to use long mould, that is this mould engages the also corresponding increase of stroke of pillar at this, so the degree of difficulty of after this joint pillar moulding finishes this mould being chosen from this hollow bulb certainly will be higher, and in the process of choosing, easily cause the physical damnification of this mould, influence its serviceable life; Moreover, the joint pillar of prior art, its wall thickness is thicker so waste material increases production cost.
Therefore, how to provide a kind of wall thickness to engage pillar uniformly, avoiding above-mentioned problem, and then improve quality, and help choosing and saving cost, the real industry problem demanding prompt solution that become of mould.
The utility model content
In view of above-mentioned prior art problems, fundamental purpose of the present utility model is to provide a kind of wall thickness to engage pillar uniformly, to improve product quality.
Another purpose of the present utility model is to provide a kind of and is easy to moulding and engages firm joint pillar.
A purpose more of the present utility model is to provide a kind of joint pillar of escapable cost.
For realizing above-mentioned fundamental purpose and other purposes, the utility model provides a kind of joint pillar, be applied at least to form by one first housing and the corresponding assembling of one second housing and between this first housing and this second housing, to be formed with in the modular device of an accommodation space, this joint pillar comprises: a support portion, be formed at this first housing on the surface of this accommodation space by first mould, and have uniform first cavity of a wall thickness; An and junction surface, be formed on this support portion by second mould, and have one and be communicated with and uniform second cavity of wall thickness with this first cavity, in order to when the corresponding assembling of this first housing and this second housing, a pair ofly should be arranged in the web member of this second housing by first housing for connecing to put, thereby make this first housing and this second housing be bonded with each other.
Wherein, above-mentioned this first cavity and this second cavity are interconnected in the mode of step, and this first cavity is gradually-reducing shape from this first housing to this accommodation space, and this second cavity is gradually-reducing shape from this accommodation space to this first housing.
Above-mentioned this first and second mould is a curved lever.
In a preferred embodiment, this support portion and this junction surface are to be made by plastic material, and this web member is a self-tapping screw; In another preferred embodiment, have screw thread on second cavity wall at this junction surface, and this web member be one with this second cavity wall on the corresponding screw of screw thread.
Than prior art, joint pillar provided by the utility model, constituted by support portion and junction surface, and in this support portion and the junction surface distinctly form first cavity and second cavity by first mould and second mould, thereby make the wall thickness of this joint pillar even, avoid causing its wall thickness can't reach evenly because of only forming a cavity, and then in forming process, take place to shrink to influence the problem of product quality by single mould as prior art; And, when injection mo(u)lding should engage pillar, the utility model is finished by size relatively short first mould and second mould, so can be convenient to moulding, and after moulding is finished and is finished, also be convenient to this mould of choosing out, reduce its wearing and tearing in the process of choosing, relatively increase the serviceable life of this mould; In addition, this wall thickness that engages pillar is even, also can save material cost, thereby avoid the wasting of resources.
