Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1 to 5, the present invention provides an airtight type water seal comprising: the water seal comprises a water seal body 1 and a hoop 2 arranged on the side face of the water seal body 1, wherein the water seal body 1 is a main structure of the water seal shown in the embodiment and can provide positioning and installation reference for other components; staple bolt 2 is the application of force part that water seal body 1 carries out the water seal function, through staple bolt 2 can realize right the water seal of water seal body 1. With respect to the above components, detailed description is given below.

Water seal body

The water seal body 1 is integrally cover-shaped, one end of the water seal body is closed, the other end of the water seal body is open, a cavity is formed in the water seal body 1, a pipeline 12 is arranged in the cavity, the pipeline 12 is divided into a pipeline 12 inner pipe and a pipeline 12 joint, the inner wall of the cavity can be attached to the outer wall of the pipeline 12 inner pipe, and the pipeline 12 inner pipe can be positioned on the water seal body 1 and is convenient to install the pipeline 12 joint. The tip of water seal body 1 has expansion ring 101, expansion ring 101 can be along with water seal body 1's stress state expands and contracts, and its concrete expression does, work as when water seal body 1 receives external force extrusion, the expansion can take place for expansion ring 101's volume, and works as when the external force that water seal body 1 received was eliminated, expansion ring 101's volume can contract, the reconversion. When the water seal body 1 is connected with the pipeline 12 joint, the expansion ring 101 is expanded by extruding the water seal body 1, and the outer side surface of the expansion ring 101 is abutted against the inner side surface of the pipeline 12 joint, so that the water seal body 1 is sealed with the pipeline 12 joint.

In order to ensure that the function of sealing the joint between the water seal body 1 and the pipeline 12 can be realized, the water seal body 1 further comprises a first limiting ring 102 and a second limiting ring 103 which are arranged on two sides of the expansion ring 101, and the inner side surfaces of the first limiting ring 102 and the second limiting ring 103 are fixedly connected with the outer side surface of the water seal body 1; the purpose of the first stop collar 102 and the second stop collar 103 is to guide the expansion ring 101 to expand in a radial direction of the expansion ring 101 instead of diverging all around, so as to ensure that the expansion ring 101 can fit and seal the joint of the pipeline 12. In addition, the space between the first limiting ring 102 and the second limiting ring 103 is small, so that the expanded volume of the expansion ring 101 can be ensured to reach the purpose of sealing the gap between the water seal body 1 and the joint of the pipeline 12. The diameter of the second limiting ring 103 is larger than that of the first limiting ring 102, the effect of the scheme is that the inner side surface of the joint of the pipeline 12 can penetrate through the first limiting ring 102 when being installed and is abutted against the end surface of the second limiting ring 103, and the second limiting ring 103 can play a role in limiting the joint of the pipeline 12.

In order to ensure water seal body 1 with pipeline 12 inner tube connected is stable, airtight type water seal is still including setting up a plurality of anti-skidding arris 9 of the medial surface of water seal body 1, anti-skidding arris 9 is the thin strip, and dyes one anti-skidding arris 9 is followed the medial surface circumference evenly distributed of water seal body 1 works as pipeline 12 inner tube inserts during water seal body 1, anti-skidding arris 9 can offset with the lateral surface of pipeline 12 inner tube, thereby increase water seal body 1 with the area of contact of pipeline 12 inner tube prevents pipeline 12 inner tube landing.

In order to limit the hoop 2, the airtight water seal further comprises a limiting plate 10 arranged on the pipeline 12, the end face of the water seal body 1 and the end face of the hoop 2 can abut against the upper surface of the limiting plate 10, the diameter of the limiting plate 10 is larger than that of the hoop 2, and the hoop 2 can slide between the limiting plate 10 and the second limiting ring 103.

In order to prevent the upper surface of the cavity and the lower bottom surface of the cavity from being attached too tightly and being unable to be separated when the airtight water seal is sealed for a long time, the airtight water seal also comprises a limit point 3 arranged on the upper surface of the cavity and a contact point 4 arranged on the lower bottom surface of the cavity; the end surface of the stopper point 3 can abut against the end surface of the contact point 4. The effect of this scheme is with laminating between cavity upper surface with bottom surface two sides under the cavity converts into the laminating between a plurality of contact to effectively reduce area of contact, prevent to laminate too tightly and can't separate.

Hoop

The hoop 2 is sleeved on the side wall of the water seal body 1, the specific position of the hoop is between the limiting plate 10 and the second limiting ring 103, the hoop 2 is a circular ring with an opening in appearance, and the two ends of the opening are respectively provided with a positioning plate 7. The airtight water seal shown in this embodiment further includes a latch plate 5, the latch plate 5 can be clamped at the end of the anchor ear 2, the length of the latch plate 5 is the same as that of the anchor ear 2, and the latch plate 5 is slidably disposed on the positioning plate 7.

In order to ensure the reliability of the sliding connection between the latch plate 5 and the positioning plate 7, the airtight water seal further comprises sliding blocks 8 arranged on two inner side surfaces of the latch plate 5 in a mirror image manner, a sliding groove 701 is formed in the side surface of the positioning plate 7, and the sliding groove 701 faces the two inner side surfaces of the latch plate 5; the sliding grooves 701 correspond to the sliding blocks 8 one by one, and the sliding blocks 8 are slidably disposed in the sliding grooves 701. When the latch plate 5 is connected to the positioning plate 7, the latch plate 5 can slide along the sliding grooves 701 to guide the sliding blocks 8 to make the latch plate 5 coincide with the side walls of the positioning plate 7.

In order to ensure the connection stability of the bolt plate 5 and the positioning plate 7, threaded holes and limit bolts 11 matched with the threaded holes are further arranged on two side walls of the bolt plate 5, and the limit bolts 11 are in threaded connection with the threaded holes. After the bolt plate 5 and the positioning plate 7 are connected and fixed, the limiting bolt 11 is screwed

The working process of the airtight water seal shown in this embodiment is that after the inner pipe of the pipeline 12 is inserted into the water seal body 1, the joint of the pipeline 12 is abutted against the second limit ring 103, at this time, the limit bolt 11 is taken out, the bolt plate 5 is horizontally rotated for half a circle, one side of the side wall with the threaded hole faces outwards, the side wall is slid into the positioning plate 7 along the sliding groove 701, when the bolt plate 5 is overlapped with the side wall of the positioning plate 7, the limit bolt 11 is inserted and screwed, the positioning plate 7 of the bolt plate 5 is fixedly connected, the limit bolt 11 is continuously screwed, the anchor ear 2 can extrude the water seal body 1, the expansion ring 101 is expanded after the water seal body 1 is extruded, and is abutted against the joint of the pipeline 12 and keeps sealing, so that the sealing of the pipeline 12 is completed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
