[0030] Furthermore, the technical solutions of the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] The utility model provides a wear-resistant rubber seal for pipe connection, aiming to solve the problem that most of the existing rubber seals for sealing the connection between two sections of wear-resistant pipes are a single whole, and when the rubber seal needs to be replaced, the whole seal needs to be replaced, which causes waste of the rubber seal, increases the burden on rubber recycling, and is inconvenient to observe whether there is slight leakage at the rubber seal.

[0032] like Figure 1-9 As shown, an anti-wear rubber seal for pipe connection provided by an embodiment of the utility model comprises a first anti-wear connecting pipe 1, a second anti-wear connecting pipe 2, a first flange 4, a second flange 3 and a plurality of bolts 5, a first rubber seal 6 is arranged on the left side of the first anti-wear connecting pipe 1, and a sealing mechanism 8 is arranged inside the first rubber seal 6;

[0033] The sealing mechanism 8 includes a second rubber seal 801, a plurality of grooves 802 and a plurality of plug-ins 803. The plug-in block 803 is fixedly connected to the surface of the second rubber seal 801 on one side close to the second rubber seal 801. The grooves 802 are provided on the inner wall of the second rubber seal 801. The surface of the second rubber seal 801 contacts the inner wall of the first rubber seal 6. The plug-in blocks 803 and the grooves 802 are evenly distributed on the surface of the second rubber seal 801 and the inner wall of the second rubber seal 801, respectively.

[0034] In the technical solution of the utility model, the first rubber seal 6 and the second rubber seal 801 can be connected to the first flange 4 by inserting the limiting column 10 on the right side of the first rubber seal 6 into the limiting hole 7, so that the first anti-wear connecting pipe 1 and the second anti-wear connecting pipe 2 are conveniently aligned and bolted with the bolt 5, and then the plug 15 is inserted into the insertion hole 16, so that the water-sensitive paper 14 contacts the gap between the first rubber seal 6 and the first flange 4 and the second flange 3. When there is a slight leakage at the first anti-wear connecting pipe 1 and the second anti-wear connecting pipe 2, the water-sensitive paper 14 will change color, and the color change of the water-sensitive paper 14 can be observed through the glass 12, so as to judge whether the second rubber seal 801 needs to be replaced. When the second rubber seal 801 needs to be replaced, the first anti-wear connecting pipe 1 and the second The anti-wear connecting pipe 2 is separated, and then the second rubber seal 801 is moved by holding the groove 802 to separate the plug block 803 from the slot 9, so that the second rubber seal 801 can be separated from the first rubber seal 6, and the second rubber seal 801 can be replaced alone, which reduces the consumption of rubber and the pressure on the recycling of waste rubber. In addition, the first anti-wear connecting pipe 1 and the second anti-wear connecting pipe 2 can be observed at any time through the water-sensing paper 14 to see if there is a slight leakage, which avoids the problem that most of the existing rubber seals for sealing the connection between the two sections of anti-wear pipes are a single whole. When the rubber seal needs to be replaced, the entire seal needs to be replaced, which causes waste of rubber seals, increases the burden on rubber recycling, and is inconvenient to observe whether there is a slight leakage at the rubber seal.

[0035] Please refer to Figure 3 and Figure 5 The left side of the first rubber seal 6 is provided with a slot 9, and the number of the slots 9 is multiple and evenly distributed on the left side of the first rubber seal 6, and the surface of the plug 803 is in close contact with the inner wall of the slot 9. In this embodiment, the second rubber seal 801 can be connected to the first rubber seal 6 by inserting the plug 803 into the slot 9, thereby achieving the effect of conveniently connecting the second rubber seal 801 to the first rubber seal 6.

[0036] For further information, please refer to Figure 2 and Fig. 9The right side of the first rubber seal 6 is fixedly connected to the limiting column 10, and the left side of the first flange 4 is provided with a limiting hole 7, and the number of the limiting holes 7 and the limiting column 10 are both three, and the limiting column 10 is movably inserted into the inside of the first flange 4. In this embodiment, the first rubber seal 6 and the second rubber seal 801 can be connected to the first flange 4 by inserting the limiting column 10 into the limiting hole 7, so as to achieve the effect of conveniently connecting the first rubber seal 6 and the second rubber seal 801 to the first flange 4.

[0037] Please continue to refer to Figure 1 and Figure 7 , a fixing frame 11 is provided on the surface of the first rubber seal 6, and the number of the fixing frames 11 is multiple. Glass 12 is inlaid inside the fixing frame 11, and a water-sensitive paper 14 is pasted on the side of the glass 12 close to the first rubber seal 6, and the surface of the water-sensitive paper 14 is in close contact with the surface of the first rubber seal 6. In this embodiment, the color change of the water-sensitive paper 14 can be observed through the glass 12. It should be noted that the water-sensitive paper 14 is an existing mature technology that has been published, and the color will change after being damp, which will not be described here. By observing the color change of the water-sensitive paper 14, it can be judged whether there is a slight leakage at the connection between the first anti-wear connecting tube 1 and the second anti-wear connecting tube 2, so as to achieve the effect of conveniently observing whether there is a slight leakage at the connection between the first anti-wear connecting tube 1 and the second anti-wear connecting tube 2.

[0038] Please refer to Figure 7 and Figure 8 The glass 12 is fixedly connected to the side close to the first rubber seal 6 with a plug post 15, the surface of the first rubber seal 6 is provided with a plug hole 16, the number of the plug holes 16 is multiple, the surface of the plug post 15 is movably plugged with the inner wall of the plug hole 16, and the side of the plug post 15 close to the water-sensitive paper 14 penetrates the water-sensitive paper 14. In this embodiment, by inserting the plug post 15 into the plug hole 16, the surface of the water-sensitive paper 14 can be brought into contact with the gap between the first rubber seal 6 and the first flange 4 and the second flange 3, so as to facilitate the water-sensitive paper 14 to absorb the leaked liquid in time.

[0039] Also, please refer to Figure 7 and Figure 8 , there is resistance at the movable connection between the plug post 15 and the plug hole 16. In this embodiment, since there is resistance at the movable connection between the plug post 15 and the plug hole 16, the surface of the water-sensitive paper 14 can be prevented from being out of contact with the surface of the first rubber seal 6, thereby achieving the effect of limiting the position of the glass 12 and the water-sensitive paper 14.

[0040] Please refer to Figure 6A pull ring 13 is fixedly connected to the side of the glass 12 away from the first rubber seal 6. In this embodiment, the glass 12 and the fixed frame 11 can be pulled by holding the pull ring 13, and the fixed frame 11 can be removed to facilitate the replacement of the water-sensitive paper 14, thereby achieving the effect of conveniently pulling the glass 12 and the water-sensitive paper 14.

[0041] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
