CN206124187U - Novel blowing hemisphere - Google Patents

Abstract

The utility model discloses a novel blowing hemisphere, including the hemispherical shell and thickening limit that adopts polyethylene blowing to form, the shell is the transparent configuration, the thickness of shell is 2mm, establish in the bottom of shell on the thickening limit, and thicken outwards salient shell 8mm of limit, still is equipped with the buckle groove outside thickening the limit, the quantity in buckle groove is two sets of, the quantity in every group buckle groove is three, wherein two buckle groove zonulae occludens together, be an angle of 90 degrees between the buckle groove that another one buckle groove and zonulae occludens are in the same place, two sets of buckle grooves use the diameter to set up at the thickening edge as the symmetry axis, with on the shell since the action of gravity gather in the thickening layer in that the unnecessary polyethylene of blow molding in -process landing is whole, and then avoided leading to deflection and diffusion owing to the thickness nonconformity, thereby make deformation and colour difference on the article of inside take place the sense organ, and establish and conveniently to fix the shell in the buckle groove of thickening edge, better stability.

Description

A kind of blow-molded plastic hemisphere

Technical field

This utility model is related to blow molding technology field, specially a kind of blow-molded plastic hemisphere.

Background technology

Blowing hemisphere is due to preferable light transmission and protective, being widely used in different occasions, and it has There is extraordinary plasticity, arbitrary shape can be made, the demand of different occasions can be met, but in actual demand, Blowing is hemispherical to be most widely used.

But in existing blow molding technology, particularly in spherical or hemispherical structure is blow molded, often due to Action of gravity and cause be blow molded hemisphere center it is thinner than side so that the structure on monolithic case is uneven, printing opacity easily occurs Property it is inconsistent caused by refraction and diffusion phenomenon, particularly in the small blow hemisphere of some Custom Prosthesis, be easy to cause There is the deformation on sense organ and color distortion in article inside hemisphere, it is impossible to the realistic reality for reflecting interior items Organoleptic parameters.

Utility model content

For problem above, this utility model provides a kind of blow-molded plastic hemisphere, addition plus webbing so that hemispherical outer The consistency of thickness of shell, is not in the difference on sense organ, can be with the problem in effectively solving background technology.

For achieving the above object, this utility model provides following technical scheme：A kind of blow-molded plastic hemisphere, including using poly- Ethylene is blow molded the hemispherical shell to be formed and adds webbing, and the shell is transparent configuration, and the thickness of the shell is 2mm, described Plus webbing is located at the bottom of shell, and add the outwardly shell 8mm of webbing, be additionally provided with buckle slot, the card on the outside of webbing adding The quantity of catching groove is two groups, and the quantity of every group of buckle slot is three, and two of which buckle slot is closely joined together, another In an angle of 90 degrees between buckle slot and the buckle slot that is closely joined together, two groups of buckle slots are built up in thickening with a diameter of axis of symmetry Bian Shang.

Used as a kind of preferred technical scheme of this utility model, the shell is semi-ellipsoid shape, and the height of the shell is 83mm, and a diameter of 147mm of shell.

Used as a kind of preferred technical scheme of this utility model, the overall diameter of described plus webbing is 173mm.

Compared with prior art, the beneficial effects of the utility model are：The blowing hemisphere, by arranging webbing is added, will be outer Because the unnecessary vinyon that action of gravity slides in blow-moulding process is all accumulated in thickening layer on shell, without It is deposited in the bottom of shell, then will can causes after the vinyon accumulation of landing the shell will not be due to the plastics had more than needed There is the phenomenon of the thin base thickness in top, and then avoid and cause the refraction and diffusion of light because variable thickness is caused, so that internally Article occur sense organ on deformation and color distortion, and be located at plus webbing on buckle slot can facilitate fixing shell, surely It is qualitative more preferable.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Embodiment：

Fig. 1 is referred to, this utility model provides a kind of technical scheme：A kind of blow-molded plastic hemisphere, including adopting polyethylene Hemispherical shell 1 and add webbing 2 that blowing is formed, the shell 1 is transparent configuration, and the thickness of the shell 1 is 2mm, described Plus webbing 2 is located at the bottom of shell 1, and add the outwardly shell 18mm of webbing 2, be additionally provided with buckle slot 3 on the outside of webbing 2 adding, The quantity of the buckle slot 3 is two groups, and the quantity of every group of buckle slot 3 is three, and two of which buckle slot 3 is close-coupled at one Rise, in an angle of 90 degrees between another buckle slot 3 and the buckle slot 3 that is closely joined together, two groups of buckle slots 3 are with a diameter of right Claim axle to be built up in add on webbing 2.

Preferably, the shell 1 is semi-ellipsoid shape, and the height of the shell 1 is 83mm, and shell 1 is a diameter of 147mm；The overall diameter of described plus webbing 2 is 173mm, it is strict limit shell 1 and plus webbing 2 parameter, further by limiting The parameter of blowing amount and each side, indirect control shell 1 and the thickness and shape size that add webbing 2, prevent due to a certain The one-sided protrusion in part and cause the disappearance for having on thickness elsewhere.

The utility model has the advantage of：The blowing hemisphere, by arrange plus webbing, by shell because action of gravity exists The unnecessary vinyon slid in blow-moulding process is all accumulated in thickening layer, the bottom without being deposited in shell, After the vinyon accumulation of landing shell will can be caused not occur pushing up showing for thin base thickness due to the plastics having more than needed again As, and then avoid and cause the refraction and diffusion of light because variable thickness is caused, so that article internally occurs on sense organ Deformation and color distortion, and be located at plus webbing on buckle slot can facilitate fixing shell, stability is more preferable.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
