Description

Toilet seat

The utility model relates to a kind of toilet, particularly relates to the toilet seat of toilet, and it is seat cushion and a lid of making toilet in one-body molded mode, and the structural strength of this toilet seat is stronger.

Generally being installed in the toilet seat at closestool body top, is to be pivoted with a seat cushion and a lid on a hinge device, makes seat cushion and lid produce the action of lifting under opening or covering with respect to closestool body for the pivot center by hinge device.

Though, general seat cushion can be put for sitting, but because of it is to form with the rigid plastics manufacturing, because the relation of material itself, so its sense of touch is cool, when temperature lower winter, the user goes to toilet and sits when putting on cushion, and its sense of touch is more uncomfortable, and in order to reach preferable structural strength, general seat cushion all has suitable thickness and weight, open to the location or be subjected to the external force effect and be rotated down when dropping when not lifting fully, tend to send the great sound, in addition because of colliding to closestool body, big more options of its lid and seat cushion same material produce the shortcoming of the big sound so it also has to drop.

The purpose of this utility model is to provide a kind of and has light weight, the sense of touch gentleness is comfortable, and the less toilet seat of noise when dropping.

Another purpose of the present utility model is to provide a kind of utilization heat, the one-shot forming of colding pressing, and makes easier toilet seat.

For achieving the above object, the utility model is taked following technical measures:

Toilet seat of the present utility model, form by a seat cushion and a lid, seat cushion is to utilize EVA (ethylene-vinyl acetate copolymer, ethene-vinyl acetate copolymer) material is made in one-body molded mode, be to sit one to put that portion's one end is one-body molded to be provided with an articulated section, and this lid also is to utilize the EVA material to make in one-body molded mode, be to be provided with a pivot portion in that cover plate one end is one-body molded, utilize articulated section and axle pivot portion to articulate mutually, can make lid produce appropriateness with respect to seat cushion pivots, the seat cushion of this toilet seat and lid have preferable structural strength, and assembling is simple.

The utility model is taked following concrete structure:

Toilet seat of the present utility model comprises a seat cushion and a lid; Seat cushion comprises sitting puts portion and articulated section, and lid comprises cover plate and axle pivot portion; It is characterized in that:

The seat of seat cushion puts portion and the articulated section is one-body molded, and the articulated section is molded over to sit puts an end of portion;

The cover plate of lid and axle pivot portion are one-body molded, and axle pivot portion is molded over an end of cover plate;

The articulated section articulates mutually with axle pivot portion.

Wherein, the seat of described seat cushion is put portion and the articulated section is one-body molded with ethene-vinyl acetate copolymer.

Wherein, the cover plate of described lid and axle pivot portion are one-body molded with ethene-vinyl acetate copolymer.

Below in conjunction with embodiment and accompanying drawing toilet seat of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the exploded perspective view of the utility model embodiment.

Fig. 2 is the front sectional elevation of the utility model embodiment.

Fig. 3 is the side cutaway view of the utility model embodiment.

As shown in Figure 1, toilet seat of the present utility model comprises a seat cushion 10 and a lid 20.Seat cushion 10 is to make in the one-body molded mode of EVA material (polymer that ethene-vinyl acetate is climbed over a wall), it is to sit one that the end put portion 11 is one-body molded to go out articulated section 12, seat is put portion 11 and is made the hollow ring round, can be for the apical margin that is placed on closestool body, and articulated section 12 includes three pivot ears 121, is provided with an axis hole 122 in each pivot ear 121 again.Lid 20 is to make in the one-body molded mode of EVA material, it is the one-body molded shaft pivot of the end portion 22 at cover plate 21, axle pivot portion 22 comprises two lugs 221, lug 221 can be for being set between two pivot ears 121 of seat cushion 10, and each lug 221 inside all is provided with a perforation 222, and perforation 222 is to be to be coaxially set with axis hole 122.

Utilize said structure, cooperate Fig. 2 again, shown in 3, when the lug 221 of lid 20 is set between two pivot ears 121 of seat cushion 10, and perforation 222 and axis hole 122 are when being coaxially set, utilize an axostylus axostyle 30 to pass perforation 222 and axis hole 122, just can make articulated section 12 and axle pivot portion 22 articulate mutually, and being produced with respect to seat cushion 10, lid 20 pivots, and when seat cushion 10 is placed on the closestool body, make again axostylus axostyle 30 two ends respectively with a holder 40 sheathed location, and on closestool body, just can make seat cushion 10 and lid 20 reach the purpose of assembling location holder 40 lockings.

Seat cushion 10 and lid 20 be because of being to make with one-body molded, so, have preferable structural strength, and utilize properties of materials, and can have light weight, sense of touch gentleness, good, the acidproof alkali of comfortableness, characteristics that collision noise is little.Toilet seat of the present utility model is to make via following step: one, cutting edge is shaped: get the EVA sheet-shaped material of tool predetermined thickness, and carry out cutting edge, grinding, make it form seat cushion or lid blank.Two, charging: the die cavity inside of seat cushion or lid blank being sent into a mould.Three, hot cold moudling: the steam transporting that utilizes boiler to produce enters mould inside, and makes seat cushion, the lid blank of die cavity inside heated by about 180 ℃ steam impringement, and can produce softening, reaction, is subjected to mold pressing effect (30～40Kg/cm ²) and through 8～10 minutes hot pressing time effect, just can make seat cushion, lid blank be subjected to the shape of die cavity inside and reach plastic compression shaping purpose, utilize cold water injection moulding mould inside again, and the inner acquisition cooling of die cavity is cooled off, and the cool time through about 15 minutes, just can make seat cushion, lid blank reach the typing purpose.Four, die sinking: can be from the inner finished product that takes out seat cushion, lid of die cavity.

Compared with prior art, the utlity model has following effect:

Because toilet seat of the present utility model is to insert mould inside with the EVA sheet-shaped material After, carry out heat in die cavity inside again, the one-shot forming of colding pressing, so, can not be subjected to environment temperature The impact that changes, the shrinkage factor when EVA is subjected to thermal response and cooling can be guaranteed to stablize, not only typing Effective, and the end product quality that produces is stable, and disqualification rate is lower. And this practicality is new Type can import Boiler Steam raw material is carried out IMPULSIVE HEATING, so the EVA sheet-shaped material can adopt Big thickness, sheet-shaped material inside also can reach enough reaction temperatures, and that periphery does not have yet is burned black Situation take place, therefore, the EVA sheet-shaped material there is no the restriction on the thickness, and finished product can be had Better structural strength. And the utility model carries out heat, cold inserting mould inside Before molded, namely the EVA sheet-shaped material is made cutting edge, edging, so made after the die sinking in advance The finished product that becomes does not almost have burr, and can reduce the process of deburring, can save manpower and simplifies Operation.

As shown in the above description, not only simple, the manufacturing assembly of technology of toilet seat of the present utility model Easily, and can reach better structural strength.
