Description

Technical Field

[0001] This application relates to the technical field of rubber rings, and in particular to a 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 the room. 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 for discharging the exhaust 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.

[0004] Currently, a platform is recessed outward from the inner wall of the exhaust pipe, and the sealing ring is placed on the top surface of the platform. With this installation method of the sealing ring and the exhaust pipe, when the installation pipe on the wall-mounted boiler is inserted into the exhaust pipe for installation, the sealing ring is prone to displacement and misalignment, resulting in poor sealing performance between the wall-mounted boiler and the exhaust duct. Summary of the Invention

[0005] In order to reduce the situation where the sealing ring is prone to displacement and misalignment, this application provides a rubber ring for a wall-mounted boiler.

[0006] A rubber ring for a wall-mounted boiler provided by this application adopts the following technical solution:

[0007] A rubber ring for a wall-mounted boiler includes a connecting plate. A clamping plate is fixed to the inner wall of the connecting plate. The clamping plate is arranged along the circumference of the connecting plate. The clamping plate is inclined, and the inclined direction of the clamping plate is from the inner wall of the connecting plate to the center of the connecting plate, sloping downward from top to bottom. An abutting plate is fixed to the inner wall of the connecting plate. The abutting plate is arranged along the circumference of the connecting plate. The abutting plate is located above the clamping plate. The abutting plate is inclined, and the inclined direction of the abutting plate is consistent with the inclined direction of the clamping plate.

[0008] By adopting the above technical solution, after the connecting plate, the clamping plate and the abutting plate are assembled, a sealing sleeve is formed. The shape of the sealing sleeve is adapted to the shape of the end of the inner wall of the exhaust pipe that needs to be sealed. The sealing sleeve is inserted into the exhaust pipe in a matching manner. The outer wall of the connecting plate abuts against the inner wall of the exhaust pipe. This application designs the shape of the sealing sleeve according to the shape of the inner wall of the exhaust pipe, thereby improving the connection stability between the sealing sleeve and the inner wall of the exhaust pipe. When the installation pipe on the wall-mounted boiler is inserted into the exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be reduced, thereby improving the sealing performance between the wall-mounted boiler and the exhaust duct.

[0009] Preferably, the thickness of the clamping plate gradually increases from the end far away from the connecting plate to the end close to the connecting plate.

[0010] By adopting the above technical solution, the thickness of the clamping plate gradually increases from the end far away from the connecting plate to the end close to the connecting plate, so that the connection area between the clamping plate and the connecting plate can be increased, the connection stability between the clamping plate and the connecting plate can be improved, the situation of fracture at the connection part between the clamping plate and the connecting plate can be reduced, and moreover, the connection area between the clamping plate and the connecting plate is relatively large, which can provide a greater supporting force for the part of the smoke exhaust pipe clamped into the clamping groove. When the smoke exhaust pipe is clamped into the clamping groove, the situation that the clamping plate is turned upwards by the upward force can be reduced.

[0011] Preferably, the thickness of the abutting plate gradually increases from the end far away from the connecting plate to the end close to the connecting plate.

[0012] By adopting the above technical solution, the thickness of the abutting plate gradually increases from the end far away from the connecting plate to the end close to the connecting plate, so that the connection area between the abutting plate and the connecting plate can be increased, and the connection stability between the abutting plate and the connecting plate can be increased.

[0013] Preferably, for the abutting plate and the clamping plate in the same vertical direction, the thickness of the abutting plate is less than that of the clamping plate.

[0014] By adopting the above technical solution, compared with the clamping plate, the thickness of the abutting plate in the same vertical direction is less than that of the clamping plate, so that the overall thickness of the abutting plate is less than that of the clamping plate. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the outer wall of the installation pipe abuts against the top surface of the abutting plate. The top surface of the abutting plate is an inclined surface, so that the resistance generated by the abutting plate to the installation pipe is small, so that the installation pipe can move downwards along the top surface of the abutting plate better. At the same time, the thickness of the abutting plate is relatively thin, so that when the outer wall of the installation pipe abuts against the abutting plate, the hardness of the abutting plate is relatively soft, and when the installation pipe abuts against the abutting plate, the abutting plate is more likely to deform, so that the inner wall of the abutting plate can better fit with the smoke exhaust pipe, reducing the situation of generating gaps between the abutting plate and the part of the smoke exhaust pipe clamped in the clamping groove. At the same time, it can also make the installation pipe and the abutting plate better abut against each other, reducing the situation of generating gaps between the installation pipe and the abutting plate.

[0015] Preferably, the bottom surface of the abutting plate is a horizontal plane, and the end of the abutting plate far away from the connecting plate is a conical structure.

[0016] By adopting the above technical solution, the bottom surface of the abutting plate is a horizontal plane, so that the end of the abutting plate far from the connecting plate is a conical structure, thereby further reducing the thickness of the end of the abutting plate far from the connecting plate, further reducing the resistance of the end of the abutting plate far from the connecting plate to the installation pipe, so that the installation pipe can more easily press against the abutting plate, and further making the inner wall of the abutting plate fit better with the smoke exhaust pipe.

[0017] Preferably, a plug-in plate is fixed on the outer wall of the connecting plate, and the plug-in plate is arranged circumferentially along the outer wall of the connecting plate.

[0018] By adopting the above technical solution, the plug-in plate is inserted into the plug-in groove on the inner wall of the smoke exhaust pipe in a matching manner. Under the action of the plug-in plate, the connection stability between the smoke exhaust pipe and the sealing sleeve can be further increased. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be further reduced.

[0019] Preferably, the plug-in plate is a conical structure, and the thickness of the plug-in plate near the connecting plate is greater than the thickness of the end far from the connecting plate.

[0020] By adopting the above technical solution, the connection area between the plug-in plate and the connecting plate can be increased, thereby increasing the connection stability between the connecting plate and the plug-in plate. At the same time, the resistance at the end of the plug-in plate far from the connecting plate can be made smaller, so that the plug-in plate can be inserted into the plug-in groove better.

[0021] Preferably, the plug-in plate is located at the bottom of the connecting plate.

[0022] By adopting the above technical solution, the top of the connecting plate is stable through the clamping plate and the abutting plate being inserted into the smoke exhaust pipe. The plug-in plate is located at the bottom of the connecting plate, so that the connection stability between the bottom of the connecting plate and the smoke exhaust pipe can be improved, and further the connection stability between the connecting plate and the smoke exhaust pipe is stronger.

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

[0024] 1. After the connecting plate, the clamping plate and the abutting plate are assembled, a sealing sleeve is formed. The shape of the sealing sleeve is adapted to the shape of the end to be sealed on the inner wall of the smoke exhaust pipe. The sealing sleeve is inserted into the smoke exhaust pipe in a matching manner, and the outer wall of the connecting plate abuts against the inner wall of the smoke exhaust pipe. The present application designs the shape of the sealing sleeve according to the shape of the inner wall of the smoke exhaust pipe, thereby improving the connection stability between the sealing sleeve and the inner wall of the smoke exhaust pipe. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be reduced, thereby improving the sealing performance between the wall-mounted boiler and the smoke exhaust duct.

[0025] 2. The plug-in board is inserted into the plug-in slot on the inner wall of the smoke exhaust pipe. Under the action of the plug-in board, the connection stability between the smoke exhaust pipe and the sealing sleeve can be further increased. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be further reduced.

[0029] The following will Figure 1-2 further describe the present application in detail.

[0030] An embodiment of the present application discloses a rubber ring for a wall-mounted boiler.

[0031] Referring to Figure 1 and Figure 2 , a rubber ring for a wall-mounted boiler includes a connecting plate 1. The connecting plate 1 is a circular ring plate. A clamping plate 2 is fixed to the inner wall of the connecting plate 1. The clamping plate 2 is arranged along the circumference of the connecting plate 1. The clamping plate 2 is inclined. The inclined direction of the clamping plate 2 is from the inner wall of the connecting plate 1 to the center of the connecting plate 1, sloping downward from top to bottom. Thus, a clamping slot 21 is formed between the connecting plate 1 and the clamping plate 2. The clamping slot 21 is a conical slot. An abutting plate 3 is fixed to the inner wall of the connecting plate 1. The abutting plate 3 is arranged along the circumference of the connecting plate 1. The abutting plate 3 is located at the top of the clamping plate 2. The abutting plate 3 is inclined. The inclined direction of the abutting plate 3 is the same as the inclined direction of the clamping plate 2. An abutting slot 31 is formed between the abutting plate 3 and the clamping plate 2.

[0032] After the connecting plate 1, the clamping plate 2 and the abutting plate 3 are assembled, a sealing sleeve is formed. The shape of the sealing sleeve is adapted to the shape of the end to be sealed on the inner wall of the smoke exhaust pipe. The sealing sleeve is inserted into the smoke exhaust pipe in a matching manner. The outer wall of the connecting plate 1 abuts against the inner wall of the smoke exhaust pipe. The present application designs the shape of the sealing sleeve according to the shape of the inner wall of the smoke exhaust pipe, thereby improving the connection stability between the sealing sleeve and the inner wall of the smoke exhaust pipe. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be reduced, thereby improving the sealing performance between the wall-mounted boiler and the smoke exhaust duct.

[0033] The sealing sleeve is a rubber sleeve, and can also be a silica gel sleeve according to different scenarios, so that the sealing sleeve has the characteristic of elasticity. The sealing sleeve is respectively pressed against the smoke exhaust pipe and the installation pipe. Due to the elasticity of the sealing sleeve, 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 sealing sleeve is adaptively clamped with the smoke exhaust pipe, thereby reducing the situation of displacement and misalignment during installation.

[0034] Refer to Figure 2 , the thickness of the clamping plate 2 gradually increases from the end far away from the connecting plate 1 to the end close to the connecting plate 1, so that the connection area between the clamping plate 2 and the connecting plate 1 can be increased, the connection stability between the clamping plate 2 and the connecting plate 1 can be improved, and the situation of fracture at the connection between the clamping plate 2 and the connecting plate 1 can be reduced. Moreover, the connection area between the clamping plate 2 and the connecting plate 1 is relatively large, which can provide a greater supporting force for the part of the smoke exhaust pipe clamped into the clamping groove 21. When the smoke exhaust pipe is clamped into the clamping groove 21, the situation that the clamping plate 2 is flipped upward by the upward force can be reduced.

[0035] Correspondingly, the thickness of the abutting plate 3 gradually increases from the end far away from the connecting plate 1 to the end close to the connecting plate 1. Compared with the clamping plate 2 in the same vertical direction, the thickness of the abutting plate 3 is less than that of the clamping plate 2, so that the overall thickness of the abutting plate 3 is less than the overall thickness of the clamping plate 2. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the outer wall of the installation pipe abuts against the top surface of the abutting plate 3. The top surface of the abutting plate 3 is an inclined surface, so that the resistance generated by the abutting plate 3 to the installation pipe is small, so that the installation pipe can move downward along the top surface of the abutting plate 3 better. At the same time, the thickness of the abutting plate 3 is relatively thin, so that when the outer wall of the installation pipe presses against the abutting plate 3, the hardness of the abutting plate 3 is relatively soft. When the installation pipe presses against the abutting plate 3, the abutting plate 3 is more likely to deform, so that the inner wall of the abutting plate 3 can better fit with the smoke exhaust pipe, reducing the situation of generating gaps between the abutting plate 3 and the part of the smoke exhaust pipe clamped in the abutting groove 31. At the same time, it can also make the installation pipe and the abutting plate 3 better pressed against each other, reducing the situation of generating gaps between the installation pipe and the abutting plate 3.

[0036] The bottom surface of the abutting plate 3 is a horizontal plane, so that the end of the abutting plate 3 far away from the connecting plate 1 is a conical structure, thereby further reducing the thickness of the end of the abutting plate 3 far away from the connecting plate 1, further reducing the resistance of the end of the abutting plate 3 far away from the connecting plate 1 to the installation pipe, so that the installation pipe is more likely to press against the abutting plate 3, and further making the inner wall of the abutting plate 3 better fit with the smoke exhaust pipe.

[0037] Refer to Figure 2, a plug-in board 4 is fixed to the bottom of the outer wall of the connecting plate 1. The plug-in board 4 is arranged along the circumference of the outer wall of the connecting plate 1. The plug-in board 4 is adaptively inserted into the plug-in slot on the inner wall of the smoke exhaust pipe. In the embodiment of the present application, the plug-in board 4 is a conical structure. The thickness of the plug-in board 4 near the connecting plate 1 is greater than the thickness of the end far from the connecting plate 1. Thereby, the connection area between the plug-in board 4 and the connecting plate 1 can be increased, and further the connection stability between the connecting plate 1 and the plug-in board 4 can be increased. At the same time, the resistance of the end of the plug-in board 4 far from the connecting plate 1 can also be made smaller, so as to facilitate the better insertion of the plug-in board 4 into the plug-in slot. Under the action of the plug-in board 4, the connection stability between the smoke exhaust pipe and the sealing sleeve can be further increased. When the installation pipe on the wall-mounted boiler is inserted into the smoke exhaust pipe for installation, the situation of displacement and misalignment of the sealing sleeve can be further reduced.

[0038] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
