Abstract

The utility model discloses a thread rotary docking launching device which is arranged on the launching port of a cleaning plate, comprising an upper connector, a seal ring, a lower connector, the upper connector and the lower connector penetrate the launching port and fix the cleaning plate to the middle to install, the utility model is characterized in that: the lower part of the upper connector is radially narrowed, and an external thread is composed; the lower connector is coatedly connected with the upper connector, the lower part thereof is also radially narrowed and an internal thread which is reelingly connected with the external thread of the upper connector is composed, such a design has the advantages of easy and labor-saving installing and dismantling, sealed and reliable connection, simple and durable structure and so on.

Description

A kind of screw thread outlet device that spins

The utility model relates to the technical field of water swivel under the container.

Traditional foil type clean container, such as culinary stainless steel cleaning disc, generally have drainage hole in the central authorities that try to get to the heart of a matter, the following water swivel sealing that is connected with sewer pipe is loaded on the drainage hole, and by two connectors and O-ring seal clamp sealing with cleaning disc up and down.Traditional clamping structure is to adopt screw, screw to be fastenedly connected, and promptly screws by the screw of drainage hole central authorities and the hold-down nut on the connector, thereby makes two connectors close mutually, and cleaning disc drainage hole cramping wherein forms leakproof and is communicated with the most at last.Because screw, the nut of fastening usefulness are less, and it is bigger to compress pressure required when sealing, and often causes the position of connector assembly nut, screw to break, be out of shape or damage easily, the sealing under the influence between water swivel and cleaning disc.

The purpose of this utility model is for overcoming the weak point of prior art, provides a kind of and install and remove easily, connect reliable, the durable screw thread of the sealing outlet device that spins.

The purpose of this utility model is achieved by the following technical solution: a kind of screw thread outlet device that spins, be loaded on the following mouth of a river of cleaning disc, include connector, sealing ring, lower connector, last connector and lower connector pass down the mouth of a river and install in the middle of cleaning disc is sandwiched in, and it is characterized in that: the bottom of going up connector is radially narrowed and is formed with external screw thread; Lower connector and last connector socket, its underpart also radially narrow and are formed with the internal thread that spins and cooperate with the external screw thread of last connector.Further, the lower external face correspondence of lower connector also is formed with external screw thread.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further elaborated.

Fig. 1 is the utility model assembling partition figure;

Fig. 2 is the sectional view of the utility model assembling.

Referring to Fig. 1-Fig. 2, present embodiment mainly constitutes by being funnelform connector 1, lower connector 2 and the sealing ring 3 gone up.Last connector 1 is loaded on the upper surface at the mouth of a river 4 under the cleaning disc, 2 soffits that are loaded on the mouth of a river 4 under the cleaning disc of lower connector, and sealing ring 3 is clipped between cleaning disc and the lower connector 2 and plays the sealed against leakage effect, special feature is that the bottom of going up connector 1 is radially narrowed and is formed with external screw thread 11, and lower connector 2 can be corresponding and last connector 1 socket, its underpart is also radially narrowed and is formed with internal thread 21, and internal thread 21 can spin with external screw thread 11 and cooperates.Like this, after the position places as shown,, tighten up between it and the last connector 1, thereby sealing ring 3 and cleaning disc are compressed sealing as long as screw lower connector 2.Certainly, in order to cooperate installing and using of cleaning disc, also can be fitted with traditional dregs separating device 5 in the last connector 1, and the lower external face correspondence of lower connector 2 is formed with the external screw thread 22 that is connected with sewer pipe, here only enumerate a kind of preferred implementation, in fact the shape of lower connector, thickness, size are variable, repeat no more here.

In sum, the screw thread that the utility model is adopted lower connector spins, and has mounting or dismounting Easily laborsaving, it is reliable to connect sealing, the advantage such as durable simple for structure.

Claims

1, a kind of screw thread outlet device that spins, be loaded on the following mouth of a river of cleaning disc, include connector, sealing ring, lower connector, last connector and lower connector pass down the mouth of a river and install in the middle of cleaning disc is sandwiched in, and it is characterized in that: the bottom of going up connector is radially narrowed and is formed with external screw thread; Lower connector and last connector socket, its underpart also radially narrow and are formed with the internal thread that spins and cooperate with the external screw thread of last connector.

2, outlet device according to claim 1 is characterized in that the lower external face correspondence of lower connector also is formed with external screw thread.
