Further, the method comprises the following steps: the thickness of the soft sleeve is gradually reduced from the position close to the threaded hole to the tail end.
Further, the method comprises the following steps: the end of the soft sleeve is closed.
Specifically, the method comprises the following steps: an air pressure balance hole is arranged between the lower end of the extrusion section and the rotating operation section.
Specifically, the method comprises the following steps: the soft cover is made of silica gel.
Specifically, the method comprises the following steps: the lower end of the extrusion section is hemispherical.
Specifically, the method comprises the following steps: the rotating operation section is of a plate-shaped structure.
The utility model has the advantages that: the extrusion section of the plug body is inserted into the soft sleeve and is sealed with the negative pressure suction tube, the soft sleeve ensures the sealing effect and is not easy to slide from the negative pressure suction tube. The clamp can be fixed in the negative pressure suction tube centre gripping on other objects, does benefit to planning and deals with the negative pressure suction tube, makes the negative pressure suction tube neatly place, also avoids the negative pressure suction tube to be polluted.
The thickness of the soft sleeve is gradually reduced from the part close to the threaded hole to the tail end, the depth of the soft sleeve and the extrusion section inserted into the negative pressure suction tube is increased, and the sealing performance and the stability of connection can be improved. The lower end of the extrusion section is hemispherical, so that the extrusion section can be inserted into the soft sleeve conveniently, and the soft sleeve can not be easily scratched by the extrusion section. The rotating operation section is of a plate-shaped structure, so that the plug body can be directly rotated by hands.
Drawings
Fig. 1 is a schematic structural view of the fixing plug of the negative pressure suction tube of the present invention.
Reference numerals: the plug comprises a clamp 1, a threaded hole 11, a plug body 2, an extrusion section 21, a fixing section 22, a rotating operation section 23 and a soft sleeve 3.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses fixed end cap of negative pressure suction tube, including clamping 1 and cock body 2, clamping 1 includes two arm lock, sets up screw hole 11 on one of them arm lock, and soft cover 3 is connected to screw hole 11's one end, the best sealing connection between soft cover 3 and the arm lock. The soft sleeve 3 is made of flexible materials, and can be made of silica gel or rubber. The plug body 2 is divided into an upper section, a middle section and a lower section according to the structure, the lower section is an extrusion section 21, and the whole plug body is cylindrical. The lower end of the extrusion section 21 is blunt, so as to avoid scratching the soft sleeve 3, for example, the lower end of the extrusion section 21 is hemispherical. The middle section of cock body 2 is fixed section 22, and the diameter of fixed section 22 is greater than the diameter of extrusion section 21, and the outside of fixed section 22 sets up the screw thread, and the screw thread and the screw hole 11 looks adaptation of fixed section 22. The upper section of the plug body 2 is a rotation operation section 23, and the rotation operation section 23 is used for rotating the plug body 2, for example, the rotation operation section 23 is a plate-shaped structure, as shown in fig. 1, which is convenient for directly rotating the plug body 2 by hand; or the upper section of the plug body 2 is of a columnar structure, and anti-skid grains are arranged on the outer side of the columnar structure. The size of the upper section of the plug body 2 is larger than the diameter of the fixing section 22, so that the rotating operation section 23 has the function of limiting the screwing depth of the fixing section 22 in the threaded hole 11.
When in use, the soft sleeve is firstly placed into the negative pressure suction tube, and automatically enters the negative pressure suction tube under the action of negative pressure; then, the extrusion section 21 of the plug body 2 passes through the threaded hole 11 and is inserted into the soft sleeve 3, so that the soft sleeve 3 is tightly contacted with the inner wall of the negative pressure suction pipe; finally, the fixing section 22 of the plug body 2 is screwed up opposite to the threaded hole 11, and the negative pressure suction tube is clamped and fixed on other objects by the clamp 1. The end of the flexible sheath 3 may be open, but is preferably closed.
When the end of the soft sleeve 3 is closed, an air pressure balance hole is arranged between the lower end of the extrusion section 21 and the rotation operation section 23, and when the extrusion section 21 is inserted into the soft sleeve 3, air between the soft sleeve 3 and the extrusion section 21 can be discharged through the air pressure balance hole. The thickness of the soft sleeve 3 is preferably gradually reduced from the part close to the threaded hole 11 to the tail end, and the combination between the negative pressure suction pipe and the extrusion section 21 is tighter by increasing the depth of the soft sleeve 3 and the extrusion section 21 inserted into the negative pressure suction pipe, so that the sealing property and the stability of the connection are improved.
