Abstract
The utility model relates to a pipe stopper, including screw rod, fastening nut, the resilient plug body, intermediate metal cover and gasket, resilient plug body suit is equipped with the looping -in groove on the resilient plug body on the screw rod, and the intermediate metal cover is installed at the looping -in inslot, the gasket suit on the screw rod, fastening nut and screw rod threaded connection to offset with the gasket, the both ends of the resilient plug body are equipped with the toper end cap, the head of screw rod still is equipped with the pull ring. The utility model discloses it is sealed effectual, extract easily.
Description
Technical field
The utility model relates to a kind of pipe stopper.
Background technique
The pipeline laid at the bottom of ground is due to needs excavation ground, general meeting is many reserved several pipelines when laying, to use from now on, this preserved pipeline needs two ends plug to block, and prevents channel interior sewage or mouse etc. from entering inside, and traditional pipe stopper adopts stopper or elastic caoutchouc to make, but this plug and inner-walls of duct area of contact large, frictional force is large, be difficult to plug to extract, and this kind of plug sealing effect is poor when needs use pipeline.
Summary of the invention
The purpose of this utility model is to provide a kind of good sealing effect, the pipe stopper easily extracted.
In order to achieve the above object, the technical solution of the utility model is: a kind of pipe stopper, comprise screw rod, tightening nut, elasticity cock body, intermediate metal cover and pad, elasticity cock body is sleeved on screw rod, and elasticity cock body is provided with annular mounting groove, intermediate metal cover is arranged in annular mounting groove, pad is sleeved on screw rod, and tightening nut is connected with screw flight, and offsets with pad, the two ends of described elasticity cock body are provided with taper plug, and the head of described screw rod is also provided with draw ring.
After adopting said structure, because elasticity cock body of the present utility model is sleeved on screw rod, when screw rod will be turned, the taper plug at elasticity cock body two ends can by screw rod, tightening nut and the compression of intermediate metal cover, there is resiliently deformable, the inwall of taper plug and pipeline is tight against, play seal action, taper plug of the present utility model has two, can double seal, good sealing effect, and the area of contact of taper plug and inner-walls of duct is little, therefore when pulled, as long as send screw rod, two taper plugs just can reset, just extract easily by draw ring.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of pipe stopper, comprise screw rod 1, tightening nut 2, elasticity cock body 3, intermediate metal cover 4 and pad 5, elasticity cock body 3 is sleeved on screw rod 1, and elasticity cock body 3 is provided with annular mounting groove 3-1, intermediate metal cover 4 is arranged in annular mounting groove 3-1, pad 5 is sleeved on screw rod 1, and tightening nut 2 is threaded with screw rod 1, and offsets with pad 5, the two ends of described elasticity cock body 3 are provided with taper plug 3-2, and the head of described screw rod 1 is also provided with draw ring 6.
Shown in Figure 1, when the utility model uses, the utility model is filled in pipeline, when turning screw rod 1 by spanner, the taper plug 3-2 at elasticity cock body 3 two ends can by screw rod 1, tightening nut 2 and intermediate metal cover 4 compression, there is resiliently deformable, the inwall of taper plug 3-2 and pipeline is tight against, play seal action, taper plug 3-2 of the present utility model has two, can double seal, good sealing effect, and the area of contact of taper plug 3-2 and inner-walls of duct is little, therefore when pulled, as long as send screw rod 1, two taper plug 3-2 just can reset, just extract easily by draw ring 6.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
