Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing parts, in particular to a self-adapting regulating device for rubber sealing parts. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent external impurities, such as dust and moisture, from invading components inside machinery and equipment. The best storage room temperature for seals is below 30°C to avoid high-temperature aging of the seals. With the increasing development of social economy, mechanical equipment has been widely used in people's production and life, and the demand for seals has gradually increased. Seals are widely used in the materials or parts of components.

[0003] The patent document with the prior art publication number CN207814416U provides a seal capable of adaptive pressure adjustment, including a left sealing block, a right sealing block and a middle sealing block, a left groove is provided inside one end of the left sealing block, a left clamping block is installed at one end of the left sealing block, a right groove is provided inside one end of the right sealing block, a right clamping block is installed at one end of the right sealing block, first grooves are provided on both sides of the middle sealing block, and the left clamping block and the right clamping block are clamped inside the first groove. The seal capable of adaptive pressure adjustment can adjust the length of the middle sealing block up and down according to different pressures by setting a telescopic block, a first spring and a rubber block, and using a first spring fixedly connected to one end of the telescopic block, and a rubber block is provided between the first springs, thereby greatly improving the applicability of the middle sealing, and can seal equipment parts of different sizes to achieve the purpose of excellent sealing effect.

[0004] However, during use of the existing rubber seal adaptive adjustment device, the sealing outer sleeve of the rubber seal needs to be sealed with the inner wall of the equipment, and the sealing inner sleeve needs to be sealed with the components of the equipment. However, after installation, the rubber seal cannot be adaptively adjusted according to demand, resulting in poor sealing effect of the rubber seal. For this reason, we propose a rubber seal adaptive adjustment device. Utility Model Content

The wear-resistant layer 10 makes the rubber seal have better wear resistance and makes the rubber seal less prone to wear damage.

[0025] In this embodiment, specifically, a reinforcement frame 13 is fixedly connected inside the rubber base material 12 . The reinforcement frame 13 is made of polytetrafluoroethylene material. The reinforcement frame 13 prevents the rubber seal from being damaged or deformed during installation.

[0026] In this embodiment, specifically, the seal body 1, the sealing outer sleeve 2 and the sealing inner sleeve 3 are an integrated structure, and the outer surfaces of the seal body 1, the sealing outer sleeve 2 and the sealing inner sleeve 3 are smooth, so that the rubber seal can be stamped and formed in one time, thereby facilitating the production of the rubber seal.

[0027] In this embodiment, specifically, the expansion spring 6 and the contraction spring 8 are made of springs, and the diameters of the expansion spring 6 and the contraction spring 8 are the same. The expansion spring 6 and the contraction spring 8 made of springs enable the sealing outer sleeve 2 and the sealing inner sleeve 3 to be precisely sealed with the installation position.
