Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipes, and specifically relates to an embedded sealing rubber sleeve device which has good sealing performance for drainage pipes and reduces the contact between the sealing sleeve and the air. Background Art

[0002] We know that in order to prevent water leakage, sealing sleeves are usually used to cover the joints of drainage pipes. However, the sealing sleeves are made of rubber materials. The larger the area exposed to the air, the more serious the aging and damage will be. The reason is that rubber materials contain a large number of weak bonds, double bonds and non-covalent bonds, which are easy to react with external environmental factors such as oxygen, ultraviolet rays, and moisture. Therefore, when we use rubber sealing sleeves for sealing, we should try to reduce the surface of the sealing sleeves exposed to the air.

[0003] When we seal the drain pipe at the bottom of the toilet, we usually buckle the rubber sealing sleeve on the port of the drain pipe. The sealing sleeve directly covers the drain pipe. Most of the surface of the sealing sleeve is exposed, and the pipe mouth is hidden inside the sealing sleeve. In this way, the sealing sleeve is very easy to age and break.

[0004] In view of this, this case came into being. Summary of the invention

[0005] The utility model aims to provide an embedded sealing rubber sleeve device which reduces the exposed area of ​​the sealing sleeve and has good sealing contact with the pipe opening of the drainage pipe in view of the deficiencies in the prior art.

[0006] The utility model is realized through the following technical scheme: an embedded sealing rubber sleeve device, which is composed of a drainage straight pipe and a rubber sleeve inserted into the port of the drainage straight pipe; it is characterized in that the port of the drainage straight pipe is provided with a double-layer caliber, and the rubber sleeve is buckled inside the double-layer caliber of the drainage straight pipe.

[0007] The rubber sleeve is composed of a double-layer ring in the shape of an annulus, the inner wall of the inner annulus is provided with an internal thread, one end of the annular surface is a closed inclined surface, and the other end is an open end.

[0008] The double-layer caliber of the straight drainage pipe is an open end.

[0009] The beneficial effect of the utility model is that compared with the prior art, after the circular rubber sleeve is buckled into the double-layer opening of the drainage pipe, the circular ring of the rubber sleeve is completely inserted into the double-layer opening, the surface in contact with the air is less, and at the same time a better sealing effect can be achieved.

[0014] The following are the specific names of the symbols in the figure: 1. Rubber sleeve; 2. Drainage straight pipe; 101. Outer annular surface; 102. Open end; 103. Inner annular surface; 104. Closed inclined surface; 201. Slot; 202. Outer layer; 203. Inner layer. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] See also Figures 1 to 3 An embedded sealing rubber sleeve device is composed of a drainage straight pipe 2 and a rubber sleeve 1 inserted into the end of the drainage straight pipe 2. The drainage straight pipe 2 is installed at the bottom of the toilet to discharge water, so the diameter of the drainage straight pipe 2 is relatively thick; a double-layer caliber is set at one end connection of the drainage straight pipe 2, namely an outer layer 202 and an inner layer 203, and a slot 201 with an opening upward is formed between the outer layer 202 and the inner layer 203.

[0017] like Figure 1 As shown, the rubber sleeve 1 is in the shape of a ring, and the ring surface is composed of a double-layer ring, namely, an outer ring surface 101 and an inner ring surface 103. The inner ring surface 103 wall is provided with an internal thread, which is used to be screwed on the threaded interface pre-set on the bottom surface of the toilet; one end of the ring surface of the rubber sleeve 1 is a closed inclined surface 104, and the other end is an open end 102. The outer ring surface 101 of the rubber sleeve 1 is embedded in the slot 201, and the inner ring surface 103 is extended into the inner layer 203 of the drainage straight pipe 2; that is, the rubber sleeve 1 is buckled on the port of the drainage straight pipe 2. When the rubber sleeve 1 is buckled on the drainage straight pipe 2, the rubber sleeve 1 is screwed on the threaded interface set on the bottom surface of the toilet. At this time, only part of the closed inclined surface 104 is exposed, and the rest of the rubber sleeve surface is all hidden inside the drainage straight pipe 2, without contact with the air, which greatly reduces the aging speed and damage time.

[0018] The double-layered opening at the upper end of the straight drainage pipe 2 of the utility model is to facilitate the inner buckling and embedding of the rubber sleeve 1, so as to hide the surface of the rubber sleeve 1 inside the double-layered opening as much as possible, and at the same time further play the role of sealing and preventing water leakage.

[0019] The utility model has an ingenious structural design of the drainage straight pipe 2 and the rubber sleeve 1, which are matched with each other and installed on the threaded interface pre-set on the bottom surface of the toilet for draining water.
