Description

Technical Field

[0001] This application relates to the technical field of sealing rubber rings, and particularly to a sealing rubber ring for a wall-mounted boiler. Background Art

[0002] A wall-mounted boiler is a household heating device. The wall-mounted boiler can be connected to the household heating system to provide heating for rooms. In addition to heating, the wall-mounted boiler can also provide domestic hot water to meet the needs of bathing, washing vegetables, etc. The wall-mounted boiler usually has a high energy efficiency ratio, which can save energy and reduce operating costs.

[0003] The wall-mounted boiler is connected with an exhaust pipe, and the exhaust pipe is used to discharge the waste gas generated by combustion. A strong sealing performance is required for the connection between the wall-mounted boiler and the exhaust pipe. Therefore, a sealing ring is often used between the wall-mounted boiler and the exhaust pipe to improve the sealing performance, thereby reducing the occurrence of smoke leakage or water leakage at the connection between the wall-mounted boiler and the exhaust pipe. However, the current sealing ring is prone to displacement and misalignment during installation, resulting in poor sealing performance between the wall-mounted boiler and the exhaust duct. Summary of the Invention

[0004] In order to reduce the displacement and misalignment of the sealing ring during installation, this application provides a sealing rubber ring for a wall-mounted boiler.

[0005] A sealing rubber ring for a wall-mounted boiler provided by this application adopts the following technical solutions:

[0006] A sealing rubber ring for a wall-mounted boiler includes a contact plate, a connecting plate and a clamping plate. The bottom surface of the connecting plate is fixedly connected to the top surface of the contact plate. One end of the bottom surface of the connecting plate far from the contact plate is fixedly connected to the top surface of the clamping plate. The contact plate and the clamping plate are arranged relatively parallel. A clamping groove is formed between the contact plate, the connecting plate and the clamping plate. The vertical length of the contact plate is greater than the vertical length of the clamping plate. A limiting plate is fixed on the side of the contact plate far from the clamping plate, and the limiting plate is arranged circumferentially along the inner wall of the contact plate.

[0007] By adopting the above technical solutions, after the contact plate, the connecting plate and the clamping plate are assembled, a clamping sleeve is formed. The shape of the clamping sleeve is adapted to the shape of the inner wall of the exhaust pipe. The clamping sleeve is clamped with the inner wall of the exhaust pipe. The bottom surface of the contact plate abuts against the top surface of the inner wall of the exhaust pipe, thereby improving the connection stability between the clamping sleeve and the exhaust pipe. When the installation pipe of the wall-mounted boiler and the exhaust pipe are installed, the installation pipe is inserted into the exhaust pipe in a matching manner. The convex plate on the outer wall of the installation pipe is inserted into the bottom of the limiting plate. The convex plate abuts against the inner wall of the contact plate. The outer wall of the installation pipe abuts against the top of the inner wall of the contact plate. The horizontal part of the outer wall of the installation pipe abuts against the top surface of the connecting plate.

[0008] The clamping sleeve abuts against the exhaust pipe and the installation pipe respectively. Due to the elasticity of the clamping sleeve, a certain contact pressure can be exerted on the abutting surface. This pressure is sufficient to fill the microscopic unevenness between the abutting surfaces, thereby reducing the leakage of gas through these tiny gaps. The clamping sleeve is adaptively clamped with the exhaust pipe, thus reducing the displacement and misalignment during installation.

[0009] Preferably, the top surface of the limiting plate is an inclined surface, and the inclined direction is downward away from the abutting plate.

[0010] By adopting the above technical solution, the top surface of the limiting plate is an inclined surface. When the installation pipe is inserted, the limiting plate can guide the installation pipe to move downward, and the resistance of the limiting plate to the downward movement of the installation pipe is small, so that the installation pipe and the convex plate can move downward along the top surface of the limiting plate better.

[0011] Preferably, the bottom surface of the limiting plate is a horizontal surface.

[0012] By adopting the above technical solution, the bottom surface of the limiting plate is a horizontal surface. When the convex plate is clamped into the limiting groove, the contact area between the convex plate and the bottom surface of the limiting plate is increased. At the same time, the limiting plate can better support the upward acting force of the convex plate, so as to better limit the convex plate and reduce the situation that the installation pipe disengages from between the limiting plates.

[0013] Preferably, the vertical cross-section of the limiting plate is a right-angled triangle surface. One right-angled surface of the limiting plate is connected to the inner wall of the abutting plate, and the bottom surface of the limiting plate is the other right-angled surface.

[0014] By adopting the above technical solution, the vertical cross-section of the limiting plate is a right-angled triangle surface, which can improve the connection area with the abutting plate, thereby improving the connection stability between the limiting plate and the abutting plate, reducing the situation of fracture between the limiting plate and the abutting plate. At the same time, it can also make the bottom surface of the limiting plate a horizontal surface and the top surface of the limiting plate an inclined surface.

[0015] Preferably, there are three limiting plates, and the three limiting plates are distributed vertically along the inner wall of the abutting plate.

[0016] By adopting the above technical solution, the two circles of convex plates on the outer wall of the installation pipe are respectively inserted into the limiting grooves close to them, so that it can better adapt to the shape of the outer wall of the installation pipe, and further improve the connection stability between the installation pipe and the clamping sleeve.

[0017] Preferably, the bottom surface of the limiting plate at the bottom is on the same horizontal plane as the bottom surface of the abutting plate.

[0018] By adopting the above technical solution, the bottom surface of the limiting plate located at the bottom is on the same horizontal plane as the bottom surface of the abutting plate, so that the contact area with the top surface of the inner wall of the exhaust pipe can be increased, the friction between the abutting plate and the exhaust pipe can be increased, and the displacement misalignment between the abutting plate and the exhaust pipe can be reduced.

[0019] Preferably, a plugging strip is fixed in the middle of the bottom surface of the connecting plate, and the plugging strip is located in the clamping groove.

[0020] By adopting the above technical solution, under the action of the plugging strips, multiple plugging strips are respectively plugged into the plugging grooves on the top surface of the exhaust pipe close to them, so as to further reduce the displacement misalignment between the clamping sleeve and the exhaust pipe.

[0021] Preferably, there are multiple plugging strips, and the multiple plugging strips are evenly distributed along the circumference of the connecting plate.

[0022] By adopting the above technical solution, there are multiple plugging strips, and the multiple plugging strips are respectively plugged into the plugging grooves on the top surface of the exhaust pipe close to them, further improving the connection stability between the clamping sleeve and the exhaust pipe.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the abutting plate, the connecting plate and the clamping plate are assembled, a clamping sleeve is formed. The shape of the clamping sleeve is adapted to the shape of the inner wall of the exhaust pipe. The clamping sleeve is clamped with the inner wall of the exhaust pipe, and the bottom surface of the abutting plate abuts against the top surface of the inner wall of the exhaust pipe, thereby improving the connection stability between the clamping sleeve and the exhaust pipe. When the installation pipe of the wall-mounted boiler is installed with the exhaust pipe, the installation pipe is inserted into the exhaust pipe in a matching manner, the convex plate on the outer wall of the installation pipe is inserted into the bottom of the limiting plate, the convex plate abuts against the inner wall of the abutting plate, the top of the outer wall of the installation pipe abuts against the inner wall of the abutting plate, and the horizontal part of the outer wall of the installation pipe abuts against the top surface of the connecting plate.

[0025] The clamping sleeve abuts against the exhaust pipe and the installation pipe respectively. Due to the elasticity of the clamping sleeve, a certain contact pressure can be applied to the abutting surface. This pressure is sufficient to fill the microscopic unevenness between the abutting surfaces, thereby reducing the leakage of gas through these tiny gaps, and the clamping sleeve is clamped with the exhaust pipe in a matching manner, thereby reducing the displacement misalignment during installation.

[0026] 2. Under the action of the plugging strips, multiple plugging strips are respectively plugged into the plugging grooves on the top surface of the exhaust pipe close to them, so as to further reduce the displacement misalignment between the clamping sleeve and the exhaust pipe.

[0031] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 for a more detailed description of the present application.

[0032] An embodiment of the present application discloses a sealing rubber ring for a wall-mounted boiler.

[0033] Referring to Figure 1 , a sealing rubber ring for a wall-mounted boiler includes a clamping sleeve 1. The clamping sleeve 1 includes an abutting plate 11, a connecting plate 12 and a clamping plate 13. The abutting plate 11, the connecting plate 12 and the clamping plate 13 are all annular plates. The bottom surface of the connecting plate 12 is fixedly connected to the top surface of the abutting plate 11. One end of the bottom surface of the connecting plate 12 far from the abutting plate 11 is fixedly connected to the top surface of the clamping plate 13. The abutting plate 11 and the clamping plate 13 are arranged relatively parallel. A clamping groove 14 is formed between the abutting plate 11, the connecting plate 12 and the clamping plate 13. The clamping groove 14 is an annular groove. The vertical length of the abutting plate 11 is greater than the vertical length of the clamping plate 13, so that the shape of the clamping sleeve 1 is adapted to the shape of the inner wall of the smoke exhaust pipe. The clamping sleeve 1 is clamped with the inner wall of the smoke exhaust pipe, and the bottom surface of the abutting plate 11 abuts against the top surface of the inner wall of the smoke exhaust pipe, thereby improving the connection stability between the clamping sleeve 1 and the smoke exhaust pipe.

[0034] Referring to Figure 2 , a limiting plate 2 is fixed on one side of the abutting plate 11 far from the clamping plate 13. The limiting plate 2 is arranged along the circumference of the inner wall of the abutting plate 11. In the embodiment of the present application, the vertical cross-section of the limiting plate 2 is a right-angled triangle surface. One right-angled surface of the limiting plate 2 is connected to the inner wall of the abutting plate 11. The bottom surface of the limiting plate 2 is the other right-angled surface, and the top surface of the limiting plate 2 is an inclined surface. The number of the limiting plates 2 is determined according to specific circumstances. In the embodiment of the present application, there are three limiting plates 2. The three limiting plates 2 are distributed along the vertical direction of the inner wall of the abutting plate 11. The bottom surface of the limiting plate 2 at the bottom is on the same horizontal plane as the bottom surface of the abutting plate 11, so as to increase the contact area with the top surface of the inner wall of the smoke exhaust pipe, increase the friction between the abutting plate 11 and the smoke exhaust pipe, and reduce the displacement and misalignment between the abutting plate 11 and the smoke exhaust pipe.

[0035] Both the clamping sleeve 1 and the limiting plate 2 are rubber plates, and they can also be silicone plates according to different scenarios, so that the clamping sleeve 1 and the limiting plate 2 have elastic characteristics. A limiting groove 21 is formed between two adjacent limiting plates 2. When the installation pipe and the smoke exhaust pipe of the wall-mounted boiler are installed, the installation pipe is inserted into the smoke exhaust pipe in a matching manner. Two rings of convex plates on the outer wall of the installation pipe are respectively inserted into the limiting grooves 21 adjacent to them. The convex plates are pressed against the inner wall of the abutting plate 11, the top of the outer wall of the installation pipe is pressed against the inner wall of the abutting plate 11, and the horizontal part of the outer wall of the installation pipe is pressed against the top surface of the connecting plate 12.

[0036] Refer to Figure 2 , the vertical section of the limiting plate 2 is a right triangle surface, which can increase the connection area with the abutting plate 11, thereby improving the connection stability between the limiting plate 2 and the abutting plate 11, and reducing the situation of fracture between the limiting plate 2 and the abutting plate 11. The top surface of the limiting plate 2 is an inclined surface, so that when the installation pipe is inserted, the limiting plate 2 can guide the installation pipe to move downward. The resistance of the limiting plate 2 to the downward movement of the installation pipe is small, so that the installation pipe and the convex plate can move downward along the top surface of the limiting plate 2 better. At the same time, the bottom surface of the limiting plate 2 is a horizontal plane. When the convex plate is stuck into the limiting groove 21, the contact area between the convex plate and the bottom surface of the limiting plate 2 is increased. At the same time, the triangle has stability, so that the limiting plate 2 can better support the upward acting force of the convex plate, thereby better limiting the convex plate and reducing the situation of the installation pipe disengaging from between the limiting plates 2.

[0037] The clamping sleeve 1 is pressed against the smoke exhaust pipe and the installation pipe respectively. Due to the elasticity of the clamping sleeve 1, a certain contact pressure can be applied to the pressing surface. This pressure is sufficient to fill the microscopic unevenness between the pressing surfaces, thereby reducing the leakage of gas through these tiny gaps. The clamping sleeve 1 is clamped with the smoke exhaust pipe in a matching manner, thereby reducing the situation of displacement and misalignment during installation.

[0038] Refer to Figure 3 , a plugging strip 3 is fixed in the middle of the bottom surface of the connecting plate 12. The plugging strip 3 is located in the clamping groove 14. There are multiple plugging strips 3, and the number of the plugging strips 3 is adapted to the number of the plugging grooves on the top surface of the part of the smoke exhaust pipe inserted into the clamping groove 14. The multiple plugging strips 3 are evenly distributed along the circumference of the connecting plate 12. Under the action of the plugging strips 3, the multiple plugging strips 3 are respectively plugged into the plugging grooves on the top surface of the smoke exhaust pipe adjacent to them, thereby further reducing the situation of displacement and misalignment between the clamping sleeve 1 and the smoke exhaust pipe.
