Abstract
The utility model belongs to a mating rat trapper for a sewer pipe network, in order to solve the problem that rats cause pollution in the existing sewer pipe. The mating rat trapper comprises an outer barrel and an inner frame, wherein the outer barrel is used for being connected with the opening of a sewer pipe; the inner frame is used for being connected with a water consumption appliance and is provided with a water discharge port; a one-way valve is mounted at the bottom of the inner frame and is sleeved in the outer barrel; the one-way valve comprises a tongue plate which is mounted on the water discharge port in the bottom of the inner frame by a torsion spring. According to the mating rat trapper for the sewer pipe network, the one-way valve is mounted at the bottom of the inner frame, when water in the water consumption appliance falls, the one-way valve is pushed open by means of gravity, and water discharge is not affected; the one-way valve seals the water discharge port in the bottom of the inner frame when the water is not discharged, and the rats cannot enter a room from the inner frame.
Description
Technical field
The utility model belongs to technical field of buildings, particularly the improvement of downcomer net.
Background technology
Existing sewer pipe is connected with washbowl, tank etc. and adopts flexible pipe to connect, and often has mouse chew off flexible pipe and enters indoorly, and particularly the sewer pipe of the public place such as school, hospital, causes cross pollution.
Summary of the invention
The utility model object is the supporting Mouseproof device of a kind of downcomer net of design, to solve the pollution problem of existing downcomer mouse.
Specifically, the supporting Mouseproof device of downcomer net, it comprise urceolus for being connected with sewer pipe mouth with for being connected the internal frame of water appliance discharge outlet, internal frame bottom is equipped with check valve and is enclosed within urceolus.Described check valve comprises a hyoplastron, and hyoplastron is contained in internal frame bottom delivery port with torsion spring.
The utility model, owing in internal frame bottom, check valve being housed, relies on gravity to push check valve open when water falls in water appliance, does not affect draining, check valve sealing internal frame bottom delivery port during not draining, and mouse cannot enter from internal frame indoor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 be in Fig. 1 A to view.
Fig. 3 is inner rack structure schematic diagram in the utility model.
Fig. 4 be in Fig. 3 B to schematic diagram.
Embodiment
Be the utility model embodiment as shown in Figure 1-2.The supporting Mouseproof device of downcomer net, it comprise urceolus 4 for being connected with sewer pipe mouth with for being connected the internal frame 2 of water appliance discharge outlet, internal frame 2 bottoms are equipped with check valve and are enclosed within urceolus 4.Described check valve 3 comprises a hyoplastron 3, and hyoplastron 3 use torsion springs are contained in internal frame 2 bottom delivery ports.Because hyoplastron is contained on internal frame delivery port by torsion spring, hyoplastron relies on enclosed elastic delivery port usually, has prevented that mouse from entering by pipeline indoor; During draining, the gravity of water makes hyoplastron beveled, does not affect draining.
