Description

Technical Field

[0001] The utility model relates to the field of rubber products, in particular to a sealing rubber ring with an inner frame. Background Art

[0002] Sealing rubber rings are usually used to fill or seal the gap between two objects; they can prevent liquid, gas or other impurities from entering the gap, and also prevent liquid or gas from leaking out. Sealing rubber rings are generally made of rubber or plastic and have good corrosion resistance and wear resistance;

[0003] Conventional X-shaped sealing rubber rings can be installed in dedicated grooves with a lower compression rate to reduce friction. X-shaped sealing rings have lower friction and can better overcome torsion, but the lip cannot withstand excessive pressure, which can cause the lip to break, thereby destroying the stress structure of the sealing ring. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a sealing rubber ring with an inner frame.

[0005] The utility model provides the following technical solutions:

[0006] A sealing rubber ring with an inner frame, comprising a base frame, a sealing ring body and an auxiliary locking ring; the base frame is a ring opening to be sealed and is provided with a clamping groove; the sealing ring body is embedded and installed in the clamping groove; the auxiliary locking ring is screwed on the base frame and locks and fixes the sealing ring body;

[0007] Furthermore, the sealing ring body is a double-layer structure, the lower layer is the sealing main ring, and the upper layer is the assembly ring; the sealing main ring and the assembly ring are integrally formed, and the diameter of the assembly ring is smaller than the sealing main ring;

[0008] Furthermore, the cross section of the sealing ring body is a convex platform composed of two rectangles;

[0009] Furthermore, a closed rubber ring is provided at the junction of the main sealing ring and the assembly ring;

[0010] Further, the auxiliary locking ring includes a locking outer ring and a locking inner ring;

[0011] Furthermore, the cross section of the closed rubber ring is circular;

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model is adopted to optimize the overall structure, and the disassembly design reduces the difficulty of later maintenance and improves the overall stability of use; the double-layer sealing ring body is matched with the closed rubber ring to achieve double sealing closure, and the bolt assembly locking outer ring and the locking inner ring further improve the overall sealing performance and reduce the probability of leakage.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] refer to Figure 1-2 As shown, a sealing rubber ring with an inner frame includes a base frame 4, a sealing ring body 1 and an auxiliary locking ring 2; the base frame 4 is a ring opening to be sealed, and is provided with a clamping groove 41; the sealing ring body 1 is embedded and installed in the clamping groove 41; the auxiliary locking ring 2 is screwed on the base frame 4, and locks and fixes the sealing ring body 1;

[0018] Furthermore, the sealing ring body 1 is a double-layer structure, the lower layer is the sealing main ring 11, and the upper layer is the assembly ring 12; the sealing main ring 11 and the assembly ring 12 are integrally formed, and the ring diameter of the assembly ring 12 is smaller than the sealing main ring 11;

[0019] Furthermore, the cross section of the sealing ring body 1 is a convex platform composed of two rectangles;

[0020] Furthermore, a closed rubber ring 3 is provided at the junction of the main sealing ring 11 and the assembly ring 12;

[0021] Furthermore, the auxiliary locking ring 2 includes a locking outer ring 21 and a locking inner ring 22;

[0022] Furthermore, the cross section of the closed rubber ring 3 is circular;

[0023] In this embodiment, the base frame 4 is the place to be sealed, and a clamping groove 41 is opened on the base hanger 4, and the clamping groove 41 is used to assemble and place the sealing ring body 1. This is the first sealing place; the opening depth of the clamping groove 41 is flush with the height of the sealing main ring 11, and a closed rubber ring 3 is embedded at the junction of the sealing main ring 11 and the assembly ring 12; the locking outer ring 21 and the locking inner ring 22 are concentrically locked and assembled on the base frame 4, the assembly ring 12 is clamped and locked, and the closed rubber ring 3 is further squeezed to form a stable second seal; the locking outer ring 21 and the locking inner ring 22 have the same height; the whole is a detachable and replaceable design, and maintenance and upgrades can be carried out as needed, and only the corresponding sealing ring body 1 needs to be replaced.
