DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Embodiment 1:
[0031] See also Figure 1-Figure 6 A combined plug assembly, whose structure includes an end cap 1, a plug assembly 2 and an adjusting assembly 3. The end cap 1 is equipped with the plug assembly 2 capable of sealing the pipeline outlet, and the end cap 1 is internally equipped with the adjusting assembly 3. The adjusting assembly 3 enables the plug assembly 2 to be applied to pipelines of different diameters.
[0032] In this embodiment, a mounting groove 11 is provided inside the end cap 1 , a plurality of through holes 12 are provided in a circular array on the end cap 1 , the through holes 12 penetrate the mounting groove 11 , and the adjustment assembly 3 is located inside the mounting groove 11 .
[0033] In this embodiment, the adjustment assembly 3 includes an adjustment member 31, a knob 32 and a tube clamp 33. One end of the adjustment member 31 is connected to the knob 32 which can drive the adjustment member 31 to rotate. The adjustment member 31 is slidably fitted with a tube clamp 33 which can clamp pipes of different diameters. The tube clamp 33 array has several groups and slidably fits with the through hole 12 on the end cap 1.
[0034] In this embodiment, the adjusting member 31 includes a slide groove 41, a driving rod 42, a limit member 43, a limit groove 44 and an anti-skid pad 45. The adjusting member 31 has a plurality of slide grooves 41 in a circular array around the center of the circle, and a driving rod 42 is slidably fitted on the plurality of slide grooves 41. A limit member 43 is installed on the other side of the adjusting member 31. The limit member 43 has a limit groove 44 in an array around the center of the circle. The limit groove 44 slidably fits with the tube clamp 33, and can limit the movement of the tube clamp 33, so that the tube clamp 33 can only slide on the limit groove 44. The outer side of the adjusting member 31 is densely covered with anti-skid pads 45 made of rubber. The anti-skid pads 45 are in contact with the inner wall of the mounting groove 11 in the end cap 1, and can prevent the adjusting member 31 from slipping, so that the adjusting member 31 will not rotate when it is not driven by the knob 32.
[0035] In this embodiment, the output end of the knob 32 passes through the end cap 1 and is connected to the center of the adjusting member 31 , so that the adjusting member 31 can be driven to rotate by rotating the knob 32 .
[0036] In this embodiment, a connecting hole 51 is opened at the bottom of the tube clamp 33, and the connecting hole 51 is connected and fixed to the driving rod 42, so that when the driving rod 42 moves under the drive of the adjusting member 31, it will drive the tube clamp 33 to move together and expand outward. The top of the tube clamp 33 is connected to an arc plate 52, and the inner side of the arc plate 52 is densely distributed with trapezoidal protrusions 53 at equal distances. The trapezoidal protrusions 53 can increase the friction of the arc plate 52 by virtue of the trapezoidal structure, so that the tube clamp 33 is not easy to slide when the pipeline is installed.
[0037] In this embodiment, a plurality of groups of pipe clamping plates 33 can be spliced together to form a circle, so as to clamp the pipes that need to be blocked and sealed.
[0038] Working principle: When it is necessary to block the pipe outlets of different diameters, the adjusting member 31 is driven to rotate by turning the knob 32. As the adjusting member 31 rotates, a plurality of driving columns 42 are driven to move simultaneously through a plurality of slide grooves 41 provided thereon. Since one end of the driving column 42 is connected to the connecting hole 51 of the pipe clamp 33, a plurality of groups of pipe clamps 33 are driven to move on the limiting groove 44 under the limiting action of the limiting member 43, thereby expanding outward, so that the end cap 1 and the plug assembly 2 can block and seal pipes of different diameters. The anti-slip pads 45 densely distributed on the outside of the adjusting member 31 are in contact with the inner wall of the mounting groove 11 in the end cap 1, which has an anti-slip effect on the adjusting member 31, so that the adjusting member 31 will not rotate when it is not driven by the knob 32.
[0039] Embodiment 2:
[0040] See also Figure 7 A combined plug assembly of the utility model, compared with the first embodiment, this embodiment also includes: the plug assembly 2 includes a base plate 21, an internal thread 22, a sealing rubber block 23, a fixing member 24 and an external thread 25, the base plate 21 is located on the end cap 1, the inner wall of the base plate 21 is provided with an internal thread 22, the base plate 21 is threadedly connected with a fixing member 24, the outer wall of the fixing member 24 is provided with an external thread 25, a sealing rubber block 23 is installed between the fixing member 24 and the base plate 21, and the sealing rubber block 23 can seal the outlet of the pipeline.
[0041] In this embodiment, the sealing rubber block 23 is movably mounted on the bottom plate 21 and the fixing member 24 and can be disassembled and replaced. When encountering pipes of different diameters, the fixing member 24 can be rotated to disengage it from the bottom plate 21, thereby losing the fixation of the sealing rubber block 23. Then, a suitable sealing rubber block 23 can be replaced according to the diameter of the pipe, thereby sealing the pipe outlet, which is convenient to use.
