[0018] The present invention will be described in detail below with reference to specific embodiments and accompanying drawings, wherein:

[0019] Figure 1 It is a top view of the first embodiment of the present invention.

[0020] Figure 2 This is a partial sectional view of the main view of the first embodiment of the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation of the present invention.

[0022] like Figures 1 to 2As shown, in order to achieve the above-mentioned purpose, the present invention proposes a flange protection device, including a limiting rod 100 that can be extended into the tube body of the flange, and the first end of the limiting rod 100 is provided with a protective cap 10 that can abut against the connecting plate of the flange, and the protective cap 10 is provided with at least one first breaking groove 20 that can break the protective cap 10 so that the size of the protective cap 10 matches the size of the connecting plate of the flange.

[0023] Specifically, a flange protection device includes a limiting rod 100 , a protection cap 10 , and a first breaking groove 20 .

[0024] The limiting rod 100 is cylindrical, and of course, according to design requirements, the limiting rod 100 can also be prismatic, such as a quadrangular prism, a pentagonal prism, etc. The shape of the limiting rod 100 is consistent with the shape of the flange body, thereby ensuring that the limiting rod 100 can extend into the flange body.

[0025] The limit rod 100 is made of a plastic material. A limit rod 100 made of a plastic material has advantages such as light weight, low cost, and ease of manufacture. Of course, depending on design requirements, the limit rod 100 can also be made of other materials to further reduce the weight of the limit rod 100, such as a foam material. A limit rod 100 made of a foam material has advantages such as light weight, low cost, and ease of breaking and reshaping. The limit rod 100 in this application is preferably made of a foam material.

[0026] The protective cap 10 is cylindrical, but can also be a cube or a cuboid depending on the design requirements. The shape of the protective cap 10 is consistent with the shape of the flange connection plate. For example, if the flange connection plate has a circular cross-section, the corresponding cross-section of the protective cap 10 is also circular; if the flange connection plate has a square cross-section, the corresponding cross-section of the protective cap 10 is also square.

[0027] The protective cap 10 is made of a foam material, which has the advantages of being lightweight, low cost, easy to manufacture, and easy to break and reshape. This allows the protective cap 10 to be easily adapted to flange connection plates of different sizes. The simple structure makes it easy to implement.

[0028] The protective cap 10 and the limiting rod 100 are connected by a fixed connection, such as by integral molding. This fixed connection can improve the connection strength and stability between the protective cap 10 and the limiting rod 100. Of course, it is conceivable that the protective cap 10 and the limiting rod 100 can also be connected by a detachable connection, such as a snap connection, a screw connection, etc. A detachable connection can facilitate installation and removal of the protective cap 10 and the limiting rod 100, facilitating subsequent maintenance.

[0029] A first breaking groove 20 is provided on the protective cap 10. When in use, the user can break the protective cap 10 along the setting direction of the breaking groove, so that the protective cap 10 can match the size of the connecting plate of the flange, thereby making the protective cap 10 adaptable to the connecting plates of flanges of different sizes. The structure is simple and easy to implement.

[0030] By adopting the above technical solution, a first breaking groove 20 is set on the protective cap 10. When in use, the limiting rod 100 is first extended into the tube body of the flange, and then the protective cap 10 is broken along the setting direction of the first breaking groove 20, so that the shape of the protective cap 10 matches the size of the connecting plate of the flange, thereby achieving compatibility with flanges of different specifications of the same pipe diameter while protecting the flange. The structure is simple and easy to implement.

[0031] In one embodiment of the present application, when there are multiple first breaking grooves 20 , the multiple first breaking grooves 20 are concentrically arranged on the protective cap 10 .

[0032] Specifically, when there are multiple first breakaway grooves 20, the term "multiple" in this application refers to two or more. The multiple first breakaway grooves 20 are concentrically arranged on the protective cap 10. By concentrically arranging them, the more first breakaway grooves 20 there are, the more compatible connection pad sizes the corresponding protective cap 10 will be. The concentric arrangement also prevents mutual interference between the first breakaway grooves 20, resulting in a simple structure and easy implementation.

[0033] In one embodiment of the present application, the protective cap 10 is further provided with a first dividing groove 30 for dividing the first breaking groove 20 into arcs.

[0034] Specifically, the protective cap 10 is provided with a first dividing groove 30. The first dividing groove 30 is cross-shaped, and the intersection of the cross-shaped first dividing groove coincides with the center of the first breaking groove 20, dividing the first breaking groove 20 into four equal parts, thereby facilitating breaking the protective cap 10. Of course, it is conceivable that the first dividing groove 30 can also divide the first breaking groove 20 into six equal parts, eight equal parts, etc., which will not be detailed here.

[0035] By adopting the above technical solution, the first breaking groove 20 is divided into arcs by providing the first dividing groove 30, thereby reducing the difficulty of breaking the protective cap 10, and the structure is simple and easy to implement.

[0036] In one embodiment of the present application, the protective cap 10 is further provided with a second breaking groove 60 which is arranged opposite to the first breaking groove 20 and has a one-to-one corresponding position.

[0037] Specifically, the protective cap 10 is further provided with a second breaking groove 60 , which is arranged opposite to the first breaking groove 20 , and the positions of the second breaking groove 60 and the first breaking groove 20 correspond to each other.

[0038] By providing the second breaking groove 60 and arranging the second breaking groove 60 opposite to the first breaking groove 20 and making the positions of the second breaking groove 60 and the first breaking groove 20 correspond one to one, the difficulty of breaking the protective cap 10 is further reduced, the structure is simple, and it is easy to implement.

[0039] In one embodiment of the present application, the protective cap 10 is further provided with a second dividing groove for dividing the second breaking groove 60 into arcs, and the second dividing groove is arranged opposite to the first dividing groove 30 and has a one-to-one correspondence in position.

[0040] Specifically, a second dividing groove is provided on the protective cap 10, which divides the second breaking groove 60 into a circular arc. At the same time, the positions of the first dividing groove 30 and the second dividing groove correspond one to one, thereby further reducing the difficulty of breaking the protective cap 10. The structure is simple and easy to implement.

[0041] In one embodiment of the present application, a groove 40 is provided in the middle of the side of the protective cap 10 away from the limiting rod 100 , and a lifting hole 50 is provided on the side wall of the groove 40 .

[0042] Specifically, a groove 40 is provided in the middle of the side of the protective cap 10 away from the limiting rod 100 , and the maximum diameter of the groove 40 is not greater than the diameter of the limiting rod 100 , thereby ensuring that the protective cap 10 is as compatible as possible with connection plates of different sizes.

[0043] A lifting hole 50 is provided on the side wall of the groove 40 , and the provision of the lifting hole 50 facilitates the installation and removal of the flange protection device, has a simple structure, and is easy to implement.

[0044] In one embodiment of the present application, the second end of the limiting rod 100 is provided with a limiting cap 90 that can abut against the inner wall of the tube body of the flange, and the limiting cap 90 is provided with at least one third breaking groove 70 that can break the limiting cap 90 so that the size of the limiting cap 90 matches the size of the inner diameter of the tube body of the flange.

[0045] Specifically, the stop cap 90 is cylindrical, but can also be a cube or a cuboid depending on the design requirements. The shape of the stop cap 90 is consistent with the shape of the inner wall of the flange. For example, if the cross-section of the inner wall of the flange is circular, the corresponding cross-section of the stop cap 90 is also circular; if the cross-section of the inner wall of the flange is square, the corresponding cross-section of the stop cap 90 is also square.

[0046] The stop cap 90 is made of a foam material, which has the advantages of being lightweight, low cost, easy to manufacture, and easy to break and reshape. This allows the stop cap 90 to easily adapt to flanges of different sizes. The simple structure makes it easy to implement.

[0047] The limiting cap 90 and the limiting rod 100 are connected by a fixed connection, such as an integral molding. The fixed connection can improve the connection strength and stability between the limiting cap 90 and the limiting rod 100. Of course, it is conceivable that the limiting cap 90 and the limiting rod 100 can also be connected by a detachable connection, such as a snap connection, a screw connection, etc. The detachable connection can facilitate the installation and removal of the limiting cap 90 and the limiting rod 100, and facilitate subsequent maintenance.

[0048] A third breaking groove 70 is provided on the limiting cap 90. When in use, the user can break the limiting cap 90 along the setting direction of the third breaking groove 70, so that the limiting cap 90 can match the size of the inner wall of the flange tube body, thereby making the limiting cap 90 adaptable to the inner wall of the flange tube body of different sizes. The structure is simple and easy to implement.

[0049] By adopting the above technical solution, by providing a limiting cap 90 and providing a third breaking groove 70 on the limiting cap 90, the limiting cap 90 can abut against the inner wall of the flange body, so that the flange protection device can adapt to flanges of different diameters.

[0050] In one embodiment of the present application, when there are multiple third breaking grooves 70 , the multiple third breaking grooves 70 are concentrically arranged.

[0051] Specifically, when there are multiple third breakaway grooves 70, the term "multiple" in this application refers to two or more. The multiple third breakaway grooves 70 are concentrically arranged on the limiting cap 90. By concentrically arranging them, the more third breakaway grooves 70 there are, the more flange pipe sizes the corresponding limiting cap 90 is compatible with. The concentric arrangement also avoids mutual interference between the third breakaway grooves 70, resulting in a simple structure and easy implementation.

[0052] In one embodiment of the present application, the limiting cap 90 is further provided with a third dividing groove for dividing the third breaking groove 70 into arcs.

[0053] Specifically, the limiting cap 90 is provided with a third dividing groove. The third dividing groove is cross-shaped, and the intersection of the cross-shaped third dividing groove coincides with the center of the third breaking groove 70, dividing the third breaking groove 70 into four equal parts, thereby facilitating the breaking of the limiting cap 90. Of course, it is conceivable that the third dividing groove can also divide the third breaking groove 70 into six equal parts, eight equal parts, etc., which will not be detailed here.

[0054] By adopting the above technical solution, the third breaking groove 70 is divided into arcs by providing the third dividing groove, thereby reducing the difficulty of breaking the limiting cap 90, and the structure is simple and easy to implement.

[0055] In one embodiment of the present application, the limiting cap 90 is further provided with a fourth breaking groove 80 which is arranged opposite to the third breaking groove 70 and has a one-to-one corresponding position.

[0056] Specifically, the protection limit cap 90 is further provided with a fourth breaking groove 80 , which is arranged opposite to the third breaking groove 70 , and the positions of the fourth breaking groove 80 and the third breaking groove 70 correspond to each other.

[0057] By setting the fourth breaking groove 80 and arranging the fourth breaking groove 80 relative to the third breaking groove 70 and making the positions of the fourth breaking groove 80 and the third breaking groove 70 correspond one to one, the difficulty of breaking the limiting cap 90 is further reduced, the structure is simple, and it is easy to implement.

[0058] In one embodiment of the present application, the limiting cap 90 is further provided with a fourth dividing groove for dividing the fourth breaking groove 80 into arcs, and the fourth dividing groove is arranged opposite to the third dividing groove and has a one-to-one correspondence in position.

[0059] Specifically, a fourth dividing groove is provided on the limiting cap 90, which divides the fourth breaking groove 80 into a circular arc. At the same time, the positions of the fourth dividing groove and the third dividing groove correspond one to one, thereby further reducing the difficulty of breaking the limiting cap 90. The structure is simple and easy to implement.
