[0002] In related technologies, some industrial control products are used in outdoor and high-humidity environments for extended periods. However, the sealing and waterproofing rings between the product's outer shell and internal structure (metal structure) are inconvenient to install and have poor sealing performance, resulting in poor waterproofing performance and thus affecting the product's service life. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a sealing and waterproof rubber ring. By setting the sealing spikes on the outer wall, the sealing spikes are more likely to deform during the assembly process, thereby filling the gap between the product shell and the outer wall of the sealing and waterproof rubber ring, improving the sealing performance, and thus improving the waterproof performance. In addition, the guide part on the sealing spikes has a good guiding function, which facilitates the installation of the sealing and waterproof rubber ring.

[0004] This utility model provides a sealing and waterproof rubber ring, comprising: The body is hollow inside and has inner and outer walls. Multiple sealing spikes are spaced around the outer wall along the extension direction of the body, and each sealing spike extends from the outer wall in a direction away from the outer wall, and each sealing spike has a guide portion formed thereon.

[0005] As an alternative, along the extension direction of the sealing barb, the size of each sealing barb gradually decreases in the direction parallel to the extension direction of the body.

[0006] As an optional solution, the body includes an assembly end, and each sealing spike has a first sidewall and a second sidewall in its extending direction. At least one of the first sidewalls and the second sidewall is inclined near the assembly end, and the inclination direction of the inclined surface near the assembly end is opposite to the assembly direction of the body. The inclined surface is configured as a guide.

[0007] As an alternative, both the first and second sidewalls are inclined surfaces, and the inclination directions of the first and second sidewalls are the same or opposite.

[0008] As an optional solution, the tilt angle of the inclined surface of each sealing spike is different.

[0009] As an optional solution, the tilt angle of the tilted surface closest to the assembly end among multiple sealing piercing surfaces is greater than the tilt angle of the other tilted surfaces.

[0010] As an optional solution, the body also includes a limiting end, which is opposite to the assembly end, and a limiting platform is provided in the area of ​​the outer wall near the limiting end. The limiting platform protrudes from the edge of the limiting end in a direction away from the outer wall, and the limiting platform is spaced apart from its adjacent sealing spike platform.

[0011] As an optional solution, the dimension of each sealing barb in its extension direction is equal to the distance between two adjacent sealing bars.

[0012] As an optional solution, multiple protrusions are arranged around the inner sidewall, with the protrusions spaced apart along the extension direction of the body, and each protrusion extending away from the inner sidewall, and the end face of each protrusion away from the inner sidewall is arc-shaped.

[0013] As an alternative, the dimension of each protrusion in its extending direction is smaller than the dimension of the sealing bar in its extending direction.

[0014] This invention relates to a sealing and waterproofing ring, comprising a hollow body with an inner wall and an outer wall.

[0017] The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are only for explaining the relevant utility model and are not intended to limit the utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the embodiments.

[0019] like Figure 1 As shown, an embodiment of this application provides a sealing and waterproofing ring 10, comprising: The body 11 is hollow inside and has an inner wall S2 and an outer wall S1. Multiple sealing spikes 12 are spaced around the outer wall S1 along the extension direction of the body 11, and each sealing spike 12 extends from the outer wall S1 in a direction away from the outer wall S1, and each sealing spike 12 has a guide portion formed thereon.

[0020] It should be noted that the body 11 serves as the supporting structure for the sealing and waterproofing ring, and is used to assemble between two components that require a sealed connection. The body 11 may be cylindrical, but is not limited to, and may be made of materials such as rubber or silicone. The body 11 is hollow inside, designed to fit over the cylindrical component, thereby achieving a sealed connection between the two components.

[0021] It is understandable that there can be two or more sealing spikes 12, depending on the actual size of the product. If the product is large, the corresponding sealing and waterproofing ring is also large, so the number of sealing spikes 12 will be large; if the product is small, the corresponding sealing and waterproofing ring is also small, so the number of sealing spikes 12 will be small.

[0022] The sealing spike 12 is a protrusion formed on the outer wall S1 of the body 11. The sealing spike 12 can be columnar, conical, or pedimental. The sealing spike 12 achieves the sealing and waterproofing function by deforming during the assembly process.

[0023] It is also understood that the guide portion can be an inclined surface S3 formed in at least a partial area of ​​the sealing spike 12. Thus, along the inclined direction of the inclined surface S3, the guide portion has a good guiding effect during the assembly of the sealing waterproof rubber ring, which facilitates the installation of the sealing waterproof rubber ring. Furthermore, due to the presence of the guide portion, the sealing spike 12 is more likely to deform, thereby achieving a reliable seal and improving the sealing and waterproof function of the sealing waterproof rubber ring.

[0024] The sealing and waterproofing ring 10 of this application solves the problems of poor sealing and waterproofing effect and inconvenient installation of sealing and waterproofing rings in related technologies. The sealing and waterproofing ring 10 of this application is formed by spaced rings around the outer wall S1 of the body 11 along the extending direction of the body 11, with each sealing spike 12 extending from the outer wall S1 in a direction away from the outer wall S1, and each sealing spike 12 having a guide portion. The arrangement of the sealing spikes 12 on the outer wall S1 of this application allows the sealing spikes 12 to deform more easily during assembly, thereby filling the gap between the product shell and the outer wall S1 of the sealing and waterproofing ring, improving sealing performance, and thus improving waterproofing performance. Furthermore, the guide portions on the sealing spikes 12 have a good guiding function, facilitating the installation of the sealing and waterproofing ring.

[0025] In some embodiments, along the extending direction of the sealing spike 12 (e.g. Figure 1 In the X direction), each sealing spike 12 extends in a direction parallel to the extension of the body 11 (e.g., in the X direction). Figure 1 The size in the Y direction gradually decreases.

[0026] The dimension of each sealing spike 12 in the direction parallel to the extension of the body 11 can be understood as the width of each sealing spike 12. The dimension of each sealing spike 12 gradually decreases in the direction parallel to the extension of the body 11, making it easier to deform during assembly and achieve sealing.

[0027] The sealing spike 12 in this embodiment has good sealing performance, which in turn helps to improve the waterproof performance of the sealing waterproof rubber ring.

[0028] As an implementation, the body 11 includes an assembly end A1, and each sealing spike 12 has a first sidewall and a second sidewall in its extending direction. At least one of the first sidewalls and the second sidewall is inclined to the sidewall near the assembly end A1, and the inclination direction of the inclined surface S3 near the assembly end A1 is opposite to the assembly direction of the body 11. The inclined surface S3 is configured as a guide.

[0029] Here, assembly end A1 refers to the end that first contacts each component during the assembly process of the sealing and waterproof rubber ring; for example, as shown in the figure, if the sealing and waterproof rubber ring is installed from top to bottom, then the lower end face is assembly end A1.

[0030] It is understandable that either the first sidewall or the second sidewall can be inclined, or both the first and second sidewalls can be inclined, as long as the sidewall closest to the assembly end A1 is inclined. The inclination direction of the inclined surface S3 closest to the assembly end A1 is opposite to the assembly direction of the body 11. For example, if the sealing waterproof ring is installed from top to bottom, then the inclined surface S3 is inclined upwards.

[0031] In this embodiment, the inclined surface S3 is configured as a guide part, which is simple in structure, easy to process, and can reliably achieve the guiding function. The inclined direction of the inclined surface S3 near the assembly end A1 is opposite to the assembly direction, which is beneficial to the convenient installation of the sealing waterproof rubber ring and to the deformation of the sealing spike 12 along the inclined direction during the installation process, so as to achieve a reliable seal.

[0032] In some embodiments, both the first sidewall and the second sidewall are inclined surfaces S3, and the inclination directions of the first sidewall and the second sidewall are the same or opposite.

[0033] The first and second sidewalls are both inclined surfaces S3, which facilitates the deformation of the sealing spike 12. When the inclined surfaces S3 of the first and second sidewalls are in the same direction, it is convenient to process and facilitates the deformation of the sealing waterproof rubber ring. When the inclined surfaces S3 of the first and second sidewalls are in opposite directions, the assembly direction of the sealing waterproof rubber ring is flexible.

[0034] In some embodiments, the tilt angle of the tilted surface S3 of each sealing spike 12 is different.

[0035] In this embodiment, the tilt angle of the inclined surface S3 of the sealing spike 12 is different, which is beneficial to improving the sealing performance and facilitating the installation of the sealing waterproof rubber ring.

[0036] In some embodiments, the tilt angle of the tilted surface S3 closest to the assembly end A1 among the plurality of sealing spikes 12 is greater than the tilt angle of the other tilted surfaces S3.

[0037] It is understandable that the sealing spike 12 closest to the assembly end A1 is the outermost sealing spike. During the assembly of the sealing waterproof rubber ring, the sealing spike 12 is the first to contact the part to be sealed compared to other sealing spikes 12. Therefore, the inclined surface S3 of the sealing spike 12 closest to the assembly end A1 has a larger inclination angle, which is beneficial to the installation of the sealing waterproof rubber ring. At the same time, the sealing spike 12 is more prone to deformation, which is beneficial to improving the sealing performance.

[0038] This embodiment facilitates the installation of the sealing and waterproofing ring, and also allows the sealing spike 12 closest to the assembly end A1 to deform, thereby achieving a seal and improving the overall waterproofing performance of the sealing and waterproofing ring.

[0039] In some embodiments, the body 11 further includes a limiting end A2, which is opposite to the assembly end A1, and a limiting platform 13 is provided in the area of ​​the outer wall S1 near the limiting end A2. The limiting platform 13 protrudes from the edge of the limiting end A2 toward a direction away from the outer wall S1, and the limiting platform 13 is spaced apart from its adjacent sealing spike platform 12.

[0040] The limiting platform 13 may be a flange or protrusion formed on the outer side wall S1 near the limiting end A2.

[0041] In actual use, the assembly end A1 of the sealing waterproof rubber ring extends into the gap between the two components, and the limiting platform 13 of the limiting end A2 overlaps the edge of the component to be sealed (e.g., Figure 2 The mutual restraint between the edge of the inner shell 1 and the component to be sealed ensures that the sealing and waterproof rubber ring is stably installed and does not move, which further improves the sealing and waterproof performance.

[0042] In some embodiments, each sealing spike 12 in its extending direction (e.g. Figure 1 The dimension of the X direction is equal to the distance between two adjacent sealing spikes 12.

[0043] The distance between two adjacent sealing spikes 12 refers to the distance between two adjacent sidewalls of two adjacent sealing spikes 12.

[0044] In this embodiment, the dimension of each sealing spike 12 in its extending direction is equal to the distance between two adjacent sealing spikes 12, which helps to ensure that the sealing spike 12 fills the entire gap after deformation, thereby improving sealing and waterproofing.

[0045] In some embodiments, a plurality of protrusions 14 are arranged around the inner sidewall S2, the plurality of protrusions 14 are spaced apart along the extension direction of the body 11, and each protrusion 14 extends toward a direction away from the inner sidewall S2, and the end face of each protrusion 14 away from the inner sidewall S2 is arc-shaped.

[0046] Among them, the multiple protrusions 14 can be arranged in a spiral manner.

[0047] In this embodiment, the protrusion 14 on the inner wall S2 is mainly used to change the contact method between the inner wall S2 of the sealing waterproof rubber ring and the internal components from surface contact to line contact or point contact during the assembly process of the sealing waterproof rubber ring, thereby reducing the contact area between the sealing waterproof rubber ring and the internal components, thereby reducing friction and improving sealing performance.

[0048] Among them, the end face of each protrusion 14 away from the side wall is arc-shaped. The arc shape makes the contact between the sealing waterproof rubber ring and the internal components point contact, which reliably reduces the contact area between the inner side wall S2 of the sealing waterproof rubber ring and the internal components.

[0049] Understandably, the dimensions of the protrusion 14 in its extending direction should be as small as possible to avoid deformation of the protrusion 14 during assembly, which would increase the contact area with internal components and increase assembly friction.

[0050] In some embodiments, the dimension of each protrusion 14 in its extending direction is smaller than the dimension of the sealing barb 12 in its extending direction.

[0051] In this embodiment, the size of the protrusion 14 is smaller than the size of the sealing spike 12, making the protrusion 14 less prone to bending and deformation, thereby reliably reducing the contact area between the inner wall S2 of the sealing waterproof rubber ring and the internal components, and ensuring effective reduction of friction.

[0052] In summary, the sealing and waterproofing ring of the embodiment of this application has a simple structure. The inclined surface S3 on the sealing spike 12 serves as a guide, which facilitates the installation of the sealing and waterproofing ring and also allows for deformation of the sealing and waterproofing ring, thus improving the sealing performance. Furthermore, the setting of the limiting platform 13 on the outer wall S1 further ensures that the sealing and waterproofing ring is not prone to displacement after installation, further improving the sealing performance. The protrusion 14 on the inner wall S2 helps to reduce the contact area between the inner wall S2 of the sealing and waterproofing ring and the internal components, reducing friction and thus facilitating the installation of the sealing and waterproofing ring.

[0053] The sealing and waterproof rubber ring 10 of this utility model will be described below through a specific embodiment.

[0054] like Figure 1-3 As shown, a sealing spike 12 is provided on the outer side wall S1 of the body 11, and each sealing spike 12 has an inclined surface S3 on the side wall near the assembly end A1 of the body 11. The inclined surface S3 is inclined toward the limiting end A2 of the body 11. A limiting platform 13 is formed in the area of ​​the outer side of the body 11 near the limiting end A2. A circular arc-shaped boss is formed spirally around the inner side wall S2 of the body 11. During assembly, the assembly end A1 of the sealing waterproof rubber ring 10 extends into the gap between the housing 1 and the connecting column 2. The inner wall S2 of the sealing waterproof rubber ring is fitted onto the outer wall of the connecting column 2. The protrusion 14 on the inner wall S2 reduces the friction between the sealing waterproof rubber ring 10 and the connecting column 2. The outer wall S1 contacts the inner wall of the housing. The sealing spike 12 is squeezed and deformed to fill the gap between the outer wall S1 and the inner wall of the housing 1. The limiting platform 13 and the step on the housing 1 mutually limit each other to fix the position of the sealing waterproof rubber ring.

Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
