Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing devices, in particular to an improved multifunctional rubber sealing device. Background Art

[0002] Rubber seals are a type of universal basic component in sealing devices. They play a very important role in the contradiction between leakage and sealing, and solve the leakage and sealing problems in the process of human conquering nature. They have always been an important way to promote technological progress and prevent and reduce environmental pollution. Rubber seals are a type of rubber product widely used in sealing technology, because rubber is a valuable elastic polymer material with a wide temperature range. When given a small stress in different media, it will produce a large deformation. This deformation can provide contact pressure, compensate for the leakage gap, and achieve the purpose of sealing.

[0003] The patent document with the prior art publication number CN202215745U provides a new type of external rubber sealing device, including a sealing member, the sealing device is composed of two or more sealing members, the longitudinal section of the sealing member is annular, the transverse section is a square structure, the sealing member is provided with a longitudinal through cut, and the cuts of two adjacent sealing members are staggered when installed. The utility model has a very wide range of applications and can replace O-shaped rubber sealing rings, rubber oil seals, etc.; the material used is rubber, the structure is simple, the performance is reliable, and it is easy to make; during installation and replacement, there is no need to disassemble other parts, just loosen the outer sealing gland.

[0004] However, there are many types of existing rubber sealing devices. During use, although some rubber sealing devices can be installed in accordance with components, the thickness of the rubber sealing devices cannot be adjusted according to installation requirements. When the rubber sealing devices are installed due to the thickness being too thin, they cannot be matched, resulting in the problem of poor practicality of the rubber sealing devices. For this reason, we propose an improved multifunctional rubber sealing device. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a technical solution: an improved multifunctional rubber sealing device, including a first sealing body 1 and a second sealing body 2, the tops of the first sealing body 1 and the second sealing body 2 are fixedly connected with a docking sleeve 5, the top center positions of the first sealing body 1 and the second sealing body 2 are each provided with a through groove 6, the top outer sides of the first sealing body 1 and the second sealing body 2 are each provided with an upper sealing groove 3, the bottom outer sides of the first sealing body 1 and the second sealing body 2 are each provided with a lower sealing groove 7, the bottom outer sides of the first sealing body 1 are movably connected with a fixed sleeve 4 through the lower sealing groove 7 and the top outer sides of the second sealing body 2 are movably connected with a docking groove 8, and the bottoms of the first sealing body 1 and the second sealing body 2 are each provided with a docking groove 8.

[0024] In the present embodiment, specifically, the outer surfaces of the first sealing body 1 and the second sealing body 2 are fixedly connected with a wear-resistant layer 9, the bottom of the wear-resistant layer 9 is fixedly connected with a high-temperature resistant layer 10, and the bottom of the high-temperature resistant layer 10 is fixedly connected with a sealing substrate 11. The wear-resistant layer 9 enables the rubber sealing device to have better wear resistance, and the high-temperature resistant layer 10 enables the rubber sealing device to withstand higher temperatures.

[0025] In this embodiment, specifically, a reinforcing material 12 is fixedly connected inside the sealing substrate 11, and the reinforcing material 12 is made of metal material. The reinforcing material 12 made of metal material makes it difficult for the rubber sealing device to be deformed and damaged during installation and use.

[0026] In this embodiment, specifically, the sealing substrate 11 is made of rubber material, and the outer surface of the sealing substrate 11 is smooth. The sealing substrate 11 made of rubber material enables the rubber sealing device to have a better sealing effect.

[0027] In the present embodiment, specifically, the first sealing body 1 and the second sealing body 2 are of the same size, and the first sealing body 1 and the second sealing body 2 are solid structures, so that the first sealing body 1 and the second sealing body 2 can be flatter after being connected, thereby ensuring the sealing effect of the rubber sealing device after installation.

[0028] In this embodiment, specifically, the inner diameter of the docking groove 8 is matched with the diameter of the docking sleeve 5, and the docking groove 8 is movably connected to the docking sleeve 5, so that the first sealing body 1 and the second sealing body 2 can be combined to be more consistent.

[0029] Working principle: After the utility model is installed, first check the installation, fixation and safety protection of the utility model. When the rubber sealing device is used, when the thickness of the rubber sealing device is too thick, the user pulls the first sealing body 1 upwards, and the docking groove 8 at the bottom of the first sealing body 1 and the docking sleeve 5 at the top of the second sealing body 2 will be separated, and then the fixing sleeve 4 can be removed from the second sealing body 2. At this time, the rubber sealing device can reduce the thickness. When the thickness is too thin, the user installs the fixing sleeve 4 on the upper sealing groove 3 of the second sealing body 2, and then docks the docking groove 8 at the bottom of the first sealing body 1 with the docking sleeve 5 at the top of the second sealing body 2. At the same time, the lower sealing groove 7 at the bottom of the first sealing body 1 will be located in the fixing sleeve 4, thereby merging the first sealing body 1 and the second sealing body 2. When the thickness is still too low, rubber sealing devices can be added in sequence to make the rubber sealing device reach the required thickness, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
