Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
A kind of pipe connecting structure of water, as shown in Figs. 1-2, including the first connecting tube 1 and the second connecting tube 2, the first connecting tube 1
Bottom end insertion be located in the top end opening of the second connecting tube 2, and the bottom outside of first connecting tube 1 and the second connecting tube
It is equipped with sealing ring 3 between 2 top end opening, then is connected and sealed by fastener 4.Specifically, fastener 4 includes being arranged
The first tight lock part 41 on the outside of the tube wall of the junction of the first connecting tube 1 and the second connecting tube 2, and it is located at the first tight lock part
41 tops are radially extended along the first connecting tube 1, second connecting tube 2, and are covered on the second tight lock part of 2 top of the second connecting tube
42.Wherein the inner sidewall of the first tight lock part 41 is provided with internal screw thread, and the lateral wall of the second connecting tube 2 is provided with and screw-internal thread fit
External screw thread, in order to which fastener 4 is threadedly connected to the second connecting tube 2.
During installation, the opposite position between the first connecting tube 1 and the second connecting tube 2 can be accordingly adjusted according to actual needs
It sets, the axial length being inserted into the second connecting tube 2 including the first connecting tube 1 and the first connecting tube 1 are connected relative to second
The rotation angle of pipe 2 screws fastener 4 after the adjustment of position, and the second tight lock part 42 of fastener 4 pushes sealing ring 3 along the at this time
The outside tube wall of one connecting tube 1, which is moved and squeezed to the direction of the second connecting tube 2, to be made sealing ring 3 deformation occurs, and sealing ring 3 is forced
It is filled between the second tight lock part 42 and the top end opening of second connecting tube 2, and the first connecting tube 1 can be partially fill in
In gap between the second connecting tube 2, to realize the sealed connection between the first connecting tube 1 and the second connecting tube 2.
The top end opening inner surface of the second connecting tube 2 in the present embodiment is provided with chamfering, the bottom end of sealing ring 3 along tube wall
The chamfering position being partially fill between second connecting tube 2 and the first connecting tube 1 is formed by accommodating space.Sealing ring 3
The lateral surface in the inlay card portion 31 including being located at bottom, inlay card portion 31 is the inclined inclined-plane of ecto-entad from top to bottom, in order to close
It fills between the first connecting tube 1 and the second connecting tube 2 bottom end of seal 3.The bottom end in inlay card portion 31 still has certain simultaneously
Thickness makes it have enough structural strengths, when sealing ring 3 is transported in the outside tube wall along the first connecting tube 1 to the second connecting tube 2
When dynamic, it can avoid the occurrence of that sealing ring 3 is influenced due to the bottom end in the inlay card portion 31 caused by frictional force effect crimps is mobile
Phenomenon.The top of sealing ring 3 has an outwardly projecting flange face of circle, and the outer diameter of the flange face is greater than the outer of inlay card portion 31
Diameter forms baffle ring on the lateral surface of sealing ring 3, which is against in the second connecting tube 2 close to the side in inlay card portion 31, into one
Step increases the sealing effect of sealing ring 3.Preferably, the outer diameter of the top end surface in inlay card portion 31 is greater than the top of the second connecting tube 2
The internal diameter of opening, and the bottom end outer diameter in inlay card portion 31 is less than the internal diameter of the top end opening of the first connecting tube 1, at this point, inlay card portion
31 lateral surface and the angle (α) of its top end face are less than the 2 top end face institute of inclined-plane and the second connecting tube of above-mentioned chamfering position
The acute angle (β) of formation, inlay card portion 31 connect in the outside tube wall by thrust along the first connecting tube 1 to the first connecting tube 1 and second
When moving between adapter tube 2, the extruding of the first connecting tube 1 and the second connecting tube 2 will receive, and inlay card portion 31 is connected at two
Elastic deformation occurs between pipe, so that sealing effect is more preferable.
When the water pipe required for user does not need rotation connection, as shown in Figure 3-4, in the first above-mentioned connecting tube 1
Stop collar 5 is equipped on lateral wall, which is located at the upper end tube nozzle of the second connecting tube 2 and the second tight lock part of fastener 4
Between 42, wherein sealing ring 3 is located at the lower section of stop collar 5, and stop collar 5 is mainly used for limiting fastener 4 in the first connecting tube 1
Position, therefore in normal use, the outer diameter of stop collar 5 needs the internal diameter greater than the second tight lock part 42, thus limitation second
The position of connecting tube 2.Common stop collar 5 and the first connecting tube 1 is integrated setting, at this point, in installation locking part, need by
Fastener 4, which is heated to the second tight lock part 42, to be sleeved in the second connecting tube 2 through stop collar 5, then by mounted fastener 4
It is cooled down to restore its original dimension and shape.
Those skilled in the art is it is to be appreciated that stop collar 5 can also be with the first connecting tube 1 by way of interference fit
It is fixedly mounted, carries out room temperature cooling by the way that the high-temperature heating expansion rear enclosure of stop collar 5 to be mounted in the first connecting tube 1, or pass through
First connecting tube 1 is placed in the low temperature environments such as liquid nitrogen to reduce its volume, then stop collar 5 is installed to the first of volume-diminished
Room temperature restores after in connecting tube 1, and the first connecting tube 1 of realization is fixedly connected with stop collar 5, then through the above way by fastener
4 are mounted in the first connecting tube 1.
It is that a kind of double flute for applying above-mentioned pipe connecting structure of water is lauched tube assembly, including bend pipe connects in conjunction with shown in Fig. 5-8
First 61, the L-type bend pipe 62 being connect with union elbow 61, the Y type convergence pipe 63 and Y type convergence pipe that are separately connected with L-type bend pipe 62
The S type deodorizing bent pipe 64 of 63 bottom connection and the hose 65 being connect with S type deodorizing bent pipe 64.Bend pipe in the lower water assembly
The connection of connector 61 and L-type bend pipe 62 uses the above-mentioned pipe connecting structure of water that can be rotated with length adjustment, such as C in Fig. 3
Shown in, by the way that one end of union elbow 61 to be inserted into L-type bend pipe 62, with fastener 4 shown in Fig. 2 and sealing ring 3
It is sealed locking；It include two L-type bend pipes 62, the connection point of two L-type bend pipes 62 and Y type convergence pipe 63 in the lower water assembly
Cai Yongliao be not above-mentioned can rotate and the pipe connecting structure of water of length adjustment, i.e. using as shown in Figure 2 at D in Fig. 3
Pipe connecting structure of water, and the pipe connecting structure of water being only able to rotate, i.e. using water pipe as shown in Figure 4 at E in Fig. 3
Connection structure.
The utility model has the advantage of while guaranteeing sealing performance, not only may be implemented between two connecting tubes
