Abstract

The utility model relates to a bath chair with simple assembly, which comprises a sitting part and a combining component, wherein, the bottom of the sitting part is provided with a tube frame which can be used for the combination of all chair legs; the combining component can be combined with a backrest bracket the upper end of which is combined with a backrest. The relative combined end of the tube frame is penetrated into each chair leg through an oblique cone, and a fixed screwing component is fixedly arranged on the combined end of the tube frame; the upper end of each chair leg which is correspondingly penetrated is sleeved with a rotary screwing component which can be integrally screwed with the fixed screwing component, therefore, the rotary screwing components of the chair legs are screwed with the fixed screwing components of the tube fame after the tube frame is penetrated into the combined end of each chair leg; the chair legs move upwards following the rotary screwing components to cause the combination between the chair legs and the tube frame is tight; further, the supporting of the chair legs is stable, and the loosening and the swinging can not happen; simultaneously, the sitting part, the chair legs, the backrest and the backrest bracket can be disassembled and folded together; as a result, the storage space and the transportation space of the bath chair are greatly reduced.

Description

The bath chair of easy assembling

Technical field

The utility model relate to a kind of can be with the structure of the bath chair taking that portion, chair pin, the chair back and chairback brace decompose and again can easy combination.

Background technology

The design of general bath chair is except allowing the user be convenient to the operation, more for producer or dealer's the storage and the cost of transportation can be reduced, simultaneously also provide the user to assemble easily, so will be designed to each parts of bath chair the structure of dismountable group type, and the formality that this mode of tearing group open is also provided convenience, as US5,845, the 962nd, make inwardly folding and closing of the chair pin and the chair back in taking in the portion, and then the occupied space of bath chair can significantly be reduced, and the operability of providing convenience, but the structure of this folding is comparatively complicated, causes the increase of bath chair cost on the contrary, and then loses the competitiveness of commodity.

Or, US2003-0102700A1 patent and for example, mainly be that bath chair is divided into the portion of taking, one chair back and four chair pin, wherein the portion of taking is provided with the pipe support that can plug together for the support on four the chair pin and the chair back, and make the place, mating side of each chair pin and chairback brace be provided with oblique cone portion, make its can with corresponding pipe support on have a corresponding tilted prick hole urgent cover cooperate, the snap-on that is installed with in simultaneously on the chair pin, enable with corresponding pipe support on the locating hole offered cooperate, so between the assembly that each two-phase interfix is closed, except urgent cooperation by two corresponding oblique cone portions, and by the firmly corresponding assembly of snap-on button hook, the assembly that allows the two-phase interfix close obtains more firm combination.

; above-mentioned US2003-0102700A1 no doubt provides the convenience of assembling; but because the position that each assembly plugs together; insurance after only depending on snap-on as the combination of two assemblies; still dislike its adhesion that weak point is arranged, particularly the chair back with take the junction of portion, under occupant's dependence repeatedly; be very easy to loosening phenomenon takes place, and then allow the occupant produce unsafe doubt.

The utility model content

The purpose of this utility model provides a kind of bath chair of easy assembling, for the steadiness that improves existing each assembly combination of forming bath chair not enough with problem such as the property guaranteed deficiency.

The practiced technology of the utility model, be order take that the portion bottom surface establishes can be for the pipe support and the coupling unit of each chair pin and chairback brace combination, and make again that this pipe support and the relative binding end of each chair pin are to be to plug together oblique cone portion mutually, make simultaneously each binding end of pipe support set firmly the solid assembly of a spiral shell again, the screw assembly that corresponding chair pin upper end then sheathed can spin together with the solid assembly of spiral shell.

A kind of bath chair of easy assembling, it comprises:

One takes portion, and its bottom surface intersection is installed with two pipe supports, makes downward the bending in two ends of this pipe support be provided with binding end, and sets firmly the solid assembly of a spiral shell at each binding end place;

One chair back, and;

Four chair pin then correspondingly in the upper end of each chair pin are provided with the binding end that the phase IPN closes, and overlap a screw assembly that screws togather mutually with the solid assembly of spiral shell again, and the binding end that makes the pipe support and the IPN mutually of chair pin close again simultaneously is to be oblique cone portion.

In addition, above-mentioned this pipe support of the present utility model is provided with corresponding concave, convex with the relative binding end place of each chair pin and the location division that can be entrenched togather.

The beneficial effects of the utility model are, after the oblique cone portion of the binding end by this pipe support of above-mentioned the utility model and each chair pin plugs together mutually, the spiral shell that tightly is threaded onto on the pipe support by the screw assembly on each chair pin is consolidated on the assembly again, the chair pin upwards driven and make outside urgent and firm between chair pin and the pipe support, and because of screw assembly and the solid combination of components coating of spiral shell, more can not take place loosening or rock, so allow the chair pin with take combining more between the portion and guarantee.

In addition, the corresponding mutual chimeric location division of pipe support of the present utility model and each chair pin, the tram in the time of can guaranteeing to assemble between chair pin and the pipe support.

Secondly, the assembling of taking between portion, chair pin, the chair back and the chairback brace of the present utility model is not only easily simple, and after each parts decomposition was come, can coincide made volume of timber space significantly reduce together, and then the cost of storage and transportation can significantly be saved.
