Description

Technical Field

[0001] The utility model relates to a dustproof pipe plug. Background Art

[0002] In the production of gas pipelines, after the gas pipelines are injection molded, they will be stored in the warehouse waiting for factory use.

[0003] During the storage of gas pipelines, since both ends of the gas pipelines are opened, this open storage will cause various dust and impurities to enter the gas pipeline during the gas flow. Such impurities entering the interior will cause the installers to deal with the impurities in advance during the later use of the pipes. Otherwise, during the later gas transportation process of the gas pipeline, the gas in the high-speed flow channel will drive the impurity flow channel, causing the pipeline filter to be blocked and affecting the gas transportation. Utility Model Content

To this end, the utility model provides a dustproof pipe plug which can be used to seal both ends of a gas pipeline to prevent dust and impurities from flowing into the interior of the pipeline during storage.

[0005] A dustproof pipe plug designed for this purpose comprises a plug cover, on which a limiting ring that fits the pipe surface is arranged, and on the outer wall surface of the plug cover a deformation element that fits the inner wall of the pipe is arranged.

[0006] Preferably, an extension portion is provided on the end surface of the plug cover facing the pipe fitting, the extension direction of the extension portion coincides with the axial direction of the pipe fitting, the interior of the extension portion is hollow to form a first operating cavity, the interior of the plug cover is hollow to form a second operating cavity, the second operating cavity is communicated with the first operating cavity, the second operating cavity is opened on one side away from the first operating cavity, a handle groove is provided on the cavity wall of the first operating cavity, and the handle groove is communicated with the first operating cavity.

[0007] Preferably, the deformation element comprises a first deformation flange arranged on the outer wall surface of the plug cover, and at least two first deformation flanges are arranged circumferentially on the outer wall surface of the plug cover.

[0008] Preferably, the deformation element further comprises a second deformation flange arranged on the outer wall surface of the plug cover, and at least two second deformation flanges are arranged circumferentially on the outer wall surface of the plug cover.

[0009] Preferably, a protrusion protruding from the inside to the outside is provided on the outer wall of the extension portion, the protrusion direction of the protrusion is perpendicular to the axial direction of the pipe fitting, and the handle groove is provided in the protrusion.

[0010] Compared with the prior art, the utility model is provided with a plug cover, a limiting ring that fits with the pipe surface is provided on the plug cover, and a deformation element that fits with the inner wall of the pipe is provided on the outer wall of the plug cover. When in use, the plug cover is inserted into the pipe, and the limiting ring fits with the pipe surface to seal and limit, while the deformation element fits with the inner wall of the pipe, and the plug cover is constrained by the interference fit between the deformation element and the inner wall of the pipe so that the plug cover is stuck at the pipe mouth, so as to seal the pipe mouth, and prevent dust and other impurities from entering the pipe when air flows.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] See also Figure 1-Figure 5 A dustproof pipe plug includes a plug cover 10, a limiting ring 20 is provided on the plug cover 10 to fit with the pipe surface 610, and a deformation element 30 is provided on the outer wall of the plug cover 10 to fit with the inner wall of the pipe 60. When in use, the plug cover is inserted into the pipe, and the limiting ring fits with the pipe surface to seal and limit, while the deformation element fits with the inner wall of the pipe, and the plug cover is constrained by the interference fit between the deformation element and the inner wall of the pipe so that the plug cover is stuck at the pipe mouth, so as to seal the pipe mouth and prevent dust and other impurities from entering the pipe when air flows.

[0018] See also Figure 3The plug cover 10 is provided with an extension portion 40 on the end surface facing the pipe fitting 60, the extension direction of the extension portion 40 coincides with the axial direction of the pipe fitting 60, the extension portion 40 is hollow inside to form a first operating cavity 410, the plug cover 10 is hollow inside to form a second operating cavity 110, the second operating cavity 110 is connected with the first operating cavity 410, the second operating cavity 110 is opened on one side away from the first operating cavity 410, a handle groove 50 is provided on the cavity wall of the first operating cavity 410, and the handle groove 50 is connected with the first operating cavity 410. In this embodiment, the stretching groove 50 is provided so that when in use, the installer can extend his hand from the second operating cavity 110 into the first operating cavity 410, then extend his finger into the handle groove 50 and use the handle groove 50 as a fulcrum to exert force to pull the entire pipe plug outward, so as to separate the pipe plug from the pipe fitting 60.

[0019] See also Figure 3 The deformation element 30 includes a first deformation flange 310 arranged on the outer wall surface of the plug cover 10. There are at least two first deformation flanges 310 arranged along the circumference on the outer wall surface of the plug cover 10.

[0020] See also Figure 3 The deformation element 30 also includes a second deformation flange 320 arranged on the outer wall of the plug cover 10. The second deformation flange 320 is at least two and arranged along the circumference on the outer wall of the plug cover 10.

[0021] The function of the first deformable flange 310 and the second deformable flange 320 is that when the plug cover 10 is inserted into the interior of the pipe fitting 60, the inner wall of the pipe fitting 60 applies a force to the first deformable flange 310 and the second deformable flange 320, causing both to deform. At the same time, since the first deformable flange 310 and the second deformable flange 320 themselves have a deformation force, the two will fit tightly against the inner wall of the pipe fitting 60, causing the plug cover to be stuck at the pipe mouth.

[0022] See also Figure 3 The outer wall of the extension portion 40 is provided with a protruding portion 500 protruding from the inside to the outside, the protruding direction of the protruding portion 500 is perpendicular to the axial direction of the pipe fitting 60, and the handle groove 50 is provided in the protruding portion 500. When the pipe plug is disassembled, the pipe plug needs to be moved along the axial direction of the pipe fitting 60 toward the side away from the pipe fitting 60, and the protruding portion 500 perpendicular to the axial direction of the pipe fitting 60 constrains the direction of the handle groove 50. The installer can extend his hand from the second operating cavity 110 into the first operating cavity 410, and then extend his finger into the handle groove 50 and use the handle groove 50 as a fulcrum to exert force to pull the entire pipe plug outward, so as to separate the pipe plug from the pipe fitting 60.
