(2) technical solution

To achieve the above object, the utility model provides the following technical solutions: a kind of subway people's air defense pipeline closure dress through walls It sets, including end cap and rubber ring, there are two the end caps, has through-hole on end cap, and rubber ring is installed between two end caps, and It is bolted to connection, it is characterised in that: an end face of the end cap is plane, is had outward on the other end of end cap Circular arc boss；There is described two end caps circular arc boss side to clamp rubber ring in opposite directions.

Preferably, there is the end face of circular arc boss outward on end cap, also there is plane in the periphery of circular arc boss.

Preferably, the acute angle α between the bus and plane of the circular arc boss is 5 ° ~ 10 °.

Preferably, the race diameter of the end cap is less than the race diameter of rubber ring (2).

Preferably, the acute angle α between the bus and plane of the circular arc boss is 5 °.

(3) beneficial effect

The utility model provides a kind of subway people's air defense pipeline plugging device through walls, have it is following the utility model has the advantages that

The utility model carries out pipeline closure by the device of mechanical structure, in the wall pipe for not exposing wall, we The plugging device of the utility model is installed in inlet pipe first, is then fastened by bolts, is squeezed by two pieces of end caps of front and back Rubber ring is not only reached the effect of protection airtight by the interference fit of rubber ring and penetration pipe, and can torn open to be later Dress is convenient.

Fig. 2 is the right side view of Fig. 1；

Fig. 3 is the structural schematic diagram of the end plate of the utility model；

Fig. 4 is the cross-sectional view in the direction A-A of Fig. 3.

In figure: 1, end cap；2, rubber ring；1-1, through-hole；3, bolt；4, circular arc boss；5, plane；As shown in the figure 6 be to wear Wall coil.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, creative work premise is not made described in those of ordinary skill in the art Under every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figs 1-4, the utility model provides a kind of embodiment: a kind of subway people's air defense pipeline plugging device through walls, packet Include end cap 1 and rubber ring 2, there are two the end caps 1, on end cap 1 have through-hole 1-1, rubber ring 2 be installed in two end caps 1 it Between, and be fixedly connected by bolt 3, it is characterised in that: an end face of the end cap 1 is plane, is had on the other end of end cap 1 There is circular arc boss 4 outward；There is described two end caps 14 side of circular arc boss to clamp rubber ring 2 in opposite directions.

When the utility model is used, the structure of the utility model is installed into wall pipe 6 first, then passes through bolt 3 Fastening squeezes rubber ring 2 by two pieces of end caps 1 of front and back, is not only reached by the interference fit of rubber ring 2 and penetration pipe 6 anti- It protects closed effect, and can be later convenient for disassembly and assembly.

There is the end face of circular arc boss 4 outward on end cap 1, also there is plane 5 in the periphery of circular arc boss 4.Pass through Imagine that two circular arc boss 4 squeeze rubber ring 2, deforms rubber ring 2 more easily outward, play the role of being completely embedded.

Acute angle α between the bus and plane 5 of the circular arc boss 4 is 5 ° ~ 10 °.Such knot with plane When structure ensure that rubber ring 2 squeezes, along the stress in tube wall direction, more serious deformation will not be generated, using effect is influenced.

The race diameter of the end cap 1 is less than the race diameter of rubber ring 2.When rubber ring 2 is squeezed and deformed, can more it connect Tube wall is touched, its frictional force is increased.

Acute angle α between the bus and plane 5 of the circular arc boss 4 that the utility model uses is 5 °.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that it is described do not depart from the principles of the present invention and spirit in the case where can to these embodiments carry out it is a variety of variation, Modification, replacement and variant, the scope of the utility model are defined by the appended claims and the equivalents thereof.
