Abstract

The utility model relates to a straight-through drainer, comprising a shell, a fastening piece, a circular ring and a rubber opening and closing device. The rubber opening and closing device is installed on an accessory grip ring at the middle part of the shell, and is fastened through the fastening piece. Protecting teeth are arranged on the inner side wall of a downcomer, below the place for installing the rubber opening and closing device. The straight-through drainer keeps rats and the like inside the sewer away from the rubber opening and closing device, protects the rubber opening and closing device from damage, and ensures the work reliability of the floor drain.

Description

The straight water trap

Technical field

The utility model relates to the sewer water trap.

Background technology

Sewer is a lot of with the floor drain kind at present, the straight odour-proof floor drain is a kind of new technology wherein, it is a kind of straight odour-proof floor drain of ZL 200520101005.X that the applicant discloses the patent No. on October 4th, 2006, this straight odour-proof floor drain mainly comprises the hole panel, securing member, housing and rubber open and close device, the rubber open and close device is installed in the sewer pipe of lower housing portion and is fastening by securing member, the hole panel then covers the water inlet place of housing upper shell, the soft rubber that the rubber open and close device is one of the forming, by upper end fixedly outer and lower end tenon shape, the outfall of the folding automatically of duckbill or V-arrangement is formed, when above-mentioned this straight odour-proof floor drain enters floor drain to rubber open and close device place as water, the outfall of rubber open and close device is opened under the effect of water gravity automatically, discharge current, the outfall of rubber open and close device is shunk automatically and is closed when draining in the water in the floor drain, reaches sealing, deodorization, the anti-water that returns, anti-breed bacteria, anti-clogging, the advantage of exempting to clean; Find that through request for utilization people for many years there are some defectives of self in above-mentioned this odour-proof floor drain, mainly having shown as in the use of rubber open and close device has individual user's family to be baited by muroid in the sewer, causes the rubber open and close device to be in the purpose that open mode does not have deodorization.Also have individual tubes to stop up, when manifold pressure is big, can knock over stripper rubber, it is indoor to cause sewage to overflow into.The new technology of application can change this situation very effectively now.

The utility model content

The purpose of this utility model is a kind of water trap; can become the water trap of multi-functional odour-proof floor drain and other function and usage with the rubber open and close device with other unit construction; it is provided with the protection tooth in the inside of following water hull body; make the animals such as muroid in the sewer can't touch the rubber open and close device, protection rubber open and close device is not damaged.Being provided with strut can prop up the rubber open and close device and not knocked over by the pressure in the lower pipeline in the securing member lower end.

The utility model is achieved in that

A kind of straight water trap; comprise housing; securing member; annulus and rubber open and close device; the housing shaped upper part has circular platform or square platform; housing upper end is inner to be provided with one or two draw-in groove and to be used for the accessory of supporting fastening other band buckle; the bottom is provided with sewer pipe; on the sewer pipe inwall, be provided with the some strong points or the segmental arc that can tangle the annulus that the rubber open and close device uses; the annulus that tangles the rubber open and close device is placed on the strong point or the segmental arc; the rubber open and close device is installed on this annulus; putting an annulus again on extension edge, rubber open and close device top locatees the rubber open and close device; the earflap shape handle of the opposition symmetry that securing member is provided with by turn Fastener inside; buckle on the securing member and the draw-in groove on the housing are cooperated reach the fastening purpose of pushing down rubber; it is characterized in that: on the lower inside wall that rubber open and close device position is set, also be provided with the protection tooth; described protection tooth has two groups to be the bilateral symmetry distribution; every group by the some protection teeth compositions that are arranged in parallel; every protection tooth direction begins to be tilted to down extension from the sewer pipe sidewall, leaves the gap between the crown of two groups of protection teeth.Its feature two is: described securing member inside has the earflap shape handle, at its lower end of two pairs of symmetries to be provided with to slope inwardly extends strut downwards, and strut is suspended on the rubber open and close device inwall.

The utility model is the improvement on the basis of original straight odour-proof floor drain, main improvement have the sewer pipe inside of housing be positioned at install rubber open and close device position below set up the protection tooth, the protection tooth is divided into two groups and crown and is tilted to down arrangement, between the crown of two groups of protection teeth, also leave the gap, the purpose first of She Zhiing can prevent that animals such as muroid from baiting the rubber open and close device in sewer like this, destroy the floor drain deodorization apparatus, the second protection tooth bearing of trend is tilted to down, can work to come water conservancy diversion, protection tooth this set can prevent effectively that floor drain from blocking; The strut main purpose of rubber open and close device top is in addition: rubber open and close device quality is soft, after the pipeline sewer pipe stops up, when the pressure in the pipeline is big, can upwards knock over rubber from the bottom, just lose original sealing, deodorization, the anti-basic function of returning water, and the strut of securing member bottom can reach and props up the rubber open and close device and do not knocked over by the pressure in the lower pipeline.And reach the anti-purpose of returning water.

The specific embodiment

As Figure 1-3, a kind of straight water trap, comprise housing 1, annulus 2, securing member 3 and rubber open and close device 4, rubber open and close device 4 is installed in the sewer pipe 11 of housing 1 bottom and is fastening by securing member 3 and annulus 2, on described sewer pipe 11 inside walls, also be provided with protection tooth 12, protection tooth 12 is positioned at the below that rubber open and close device 4 positions are installed, described protection tooth 12 has two groups to be the bilateral symmetry distribution, every group by the some protection teeth compositions that are arranged in parallel, every protection tooth 12 directions begin to be tilted to down extension from the sewer pipe sidewall, leave the gap between the crown of two groups of protection teeth 12; Also be provided with strut 31 below described securing member, strut 31 is suspended on rubber open and close device 4 inwalls.

The utility model has been established strut and protection tooth respectively at rubber open and close device upper and lower, the protection tooth can prevent effectively in the sewer that animal such as muroid climbs up the possibility of baiting the rubber folding, protect tooth when draining, can play the effect of water conservancy diversion simultaneously, leave the gap between two groups of protection teeth, be unlikely to when draining, to block sewer pipe; And the strut of securing member bottom can reach and props up the rubber open and close device and do not knocked over by the pressure in the pipeline of bottom.And reach the anti-purpose of returning water.
