Description

Toilet lifting device

Technical field

The utility model relates to the device that supports bedpan and water tank in a kind of water closet that can adjust the bedpan height.

Background technology

The water closet that is fixedly mounted in the lavatory has bedpan, ring and water tank.The height of bedpan and the size of ring are generally according to adult stature design.When children use such water closet, will feel that bedpan is too high.For family or most public place, then because the restriction of lavatory area is difficult to not only be mounted to the water closet of human but also the water closet that children use is installed.For this reason, people propose to make the lifting gear of water closet, solve this problem by the height of adjusting bedpan.For example, it is ZL 96215113.0 that Chinese utility model patent manual CN 2290298Y discloses the patent No., and name is called the technical scheme of " multifunctional lifting formula water closet ", proposes to be provided with the bedpan of installation water closet and the carriage of water tank; This carriage is by being fixedly mounted on the leverage supporting that hoists of jack on the base plate.The jack leverage that hoists is made up of hydraulic jack, crossbeam, two pull bars, two groups of middle parts by the middle part of fixed bar (following fixed arm) down and last fixed bar (last fixed arm) the X-shaped support (lever hoists) that forms that is hinged.Hydraulic jack is fixedly mounted on the base plate, and the push rod of jack withstands crossbeam, and each is hinged the two ends of crossbeam with the upper end of a pull bar.The lower end of every pull bar is hinged on the middle and lower part of fixed bar under the vertical one group of X-shaped support installing in a carriage left side or right side accordingly.Descend the lower end of fixed bar to be hinged on the base plate in every group of X-shaped support, the upper end of following fixed bar is provided with the pulley that moves on carriage; The upper end of fixed bar is hinged on the carriage on every group of X-shaped support, and the lower end of last fixed bar is provided with the pulley that moves on base plate.The push rod of hydraulic jack upwards rises, two hinged pull bars of crossbeam two ends are upwards carried following fixed bar in the corresponding X-shaped support, the upper end of the fixed bar swing on correspondence respectively of the upper end of two following fixed bars, promptly two groups of X-shaped supports are done the gathering of vertical direction, carriage is elevated, thereby the bedpan of water closet and water tank are raised.Otherwise, the push rod of hydraulic jack is to decline, two hinged pull bars of crossbeam two ends are no longer upwards carried following fixed bar in the corresponding X-shaped support, under the action of gravity of water closet bedpan and water tank, carriage to the following fixed bar of two groups of X-shaped supports and last fixed bar apply upper end that vertically downward pressure makes two following fixed bars respectively on away from correspondence the direction of fixed bar upper end move, promptly two groups of X-shaped supports are done the gathering of horizontal direction, and carriage is lowered, thereby the bedpan of water closet and water tank are lowered.This technical scheme causes having following shortcoming owing to adopt hydraulic jack: 1, and the hoist complex structure of leverage of jack, cost height.2, lift adjustment is dumb.

The utility model content

The utility model aims to provide a kind of simple in structure and lift adjustment toilet lifting device flexibly.

The technical solution of the utility model is: toilet lifting device has the bedpan of installation water closet and the carriage of water tank; This carriage is provided with electric motor driven master gear, this master gear drives at least three identical driven gears that are arranged at bracket perimeter respectively by cingulum, the rotating shaft of each driven gear connects a screw rod that extends separately downwards, and every screw rod is screwed together in upwardly extending screwed pipe corresponding on the base plate separately.This lifting gear adopts Motor Drive, the operator only need be with a finger presses gauge tap, the Motor Drive master gear makes at least three identical driven gears drive screw rods separately that are arranged at bracket perimeter respectively by cingulum, screw in or screw out screwed pipe corresponding on the base plate, just can control closet body and fall or rise.This lifting device structure is simple, and the mechanical strength height is controlled conveniently, and lift adjustment is flexible.

In the embodiment that recommends: the rear portion that described master gear is arranged on carriage is positioned at the place, below of water tank.So, master gear and motor can be hidden in the rear of bedpan and ring, do not influence the normal use of bedpan and ring.

And then: described driven gear is divided into two groups, is arranged at the carriage and arranged on left and right sides respectively; Every group has three identical driven gears at least, wherein is positioned to install one in the driven gear rotating shaft at carriage rear portion and go up driven gear and a following driven gear, and a following driven gear is installed in the driven gear rotating shaft of bracket front part; Master gear drives last driven gear in these two groups by first cingulum, and the following driven gear that is arranged in the carriage rear portion in every group drives the following driven gear that this group is positioned at bracket front part by second cingulum of this side.Two groups of driven gears are respectively along the and arranged on left and right sides setting of carriage, promptly two groups of driven gears with screw rod and base plate on corresponding screwed pipe respectively along the and arranged on left and right sides setting of carriage; Like this, this lifting gear can stress equalization and is carried out lift work reposefully.

In the enforcement structure of recommending: described carriage comprises corresponding up and down bracket and the bottom bracket that is provided with; Water closet bedpan and water tank are installed on the bracket, and master gear and two go up the top that driven gear and first cingulum are arranged on bracket; Four following driven gears and two second cingulums are arranged between bracket and the bottom bracket; The rotating shaft that corresponding this driven gear of bearing socket is established in the rotating shaft of corresponding each driven gear respectively on bracket and the bottom bracket.Four following driven gears and two second cingulums are arranged between bracket and the bottom bracket, can reserve necessary space for the installation of bedpan and ring.The rotating shaft of the corresponding driven gear of bearing socket is set on bracket and bottom bracket, support each driven gear and screw rod thereof by bracket and bottom bracket, make them constitute organic whole, help the stable operation of second cingulum and each screw rod balance and rotation and lifting synchronously stably.

Particularly: on the described base plate fixedly connected with the underframe of annular in the top of each screwed pipe.By means of the stability of each screwed pipe on the underframe raising base plate, also just improved the stability of rotation synchronously of each screw rod and lifting.

The utility model toilet lifting device utilizes Motor Drive master gear, cingulum, driven gear, and each driven gear drives screw rod separately, screws in or screws out screwed pipe corresponding on the base plate, makes closet body fall or rise.Compare with the existing lifting gear of X-shaped support that adopts, have simple in structure, mechanical strength is high, control convenient and lift adjustment advantage flexibly.Its price is low, and reliability is higher.
