Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a flame-retardant battery silicone sealing ring. Background Art

[0002] Sealing rings are commonly used mechanical components, primarily for preventing fluid or gas leakage. They are widely used in various mechanical devices, such as pumps, valves, hydraulic systems, and pneumatic tools, to ensure the sealing performance of the equipment. Sealing rings are typically made of elastic materials such as rubber, silicone, and polyurethane. Different materials and types of sealing rings are selected according to different usage environments and requirements.

[0003] For some special occasions, the sealing ring needs to have good flame retardancy to ensure the normal operation of the equipment and the safety of personnel; however, the complete use of flame retardant materials will undoubtedly increase costs, and when replacement is needed, the entire ring needs to be replaced.

[0004] The main reasons for the deformation of the sealing ring include the bite caused by the product squeezing into the gap: the sealing ring may be squeezed into the sealing gap during use, causing bites and damage.

[0005] In view of this, the inventor specially designed a flame-retardant battery silicone seal ring, which resulted in this case. Utility Model Content

[0006] The purpose of this utility model is to provide a flame-retardant battery silicone sealing ring, which is specially designed for seals in battery applications. It not only has good sealing performance, but also has excellent flame retardant properties and makes full use of resources, reducing the frequency of overall replacement of the sealing ring.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A flame-retardant battery silicone seal ring comprises a connecting ring, an upper cover ring, a lower cover ring and two semicircular spacers; a groove is provided in an annular shape on the outer wall of the connecting ring; the upper cover ring is provided on the upper end of the connecting ring and is located above the groove, and is used to prevent the intrusion of external impurities; the inner sides of the two spacers are embedded in the groove and surround the entire circumference of the connecting ring; the lower cover ring is provided on the connecting ring at the lower end of the spacer, and the lower cover ring abuts against the battery and separates the battery from the connecting ring.

[0009] Furthermore, an annular protrusion is provided on the outer side wall of the connecting ring protruding outward; and the groove is provided on the annular protrusion.

[0010] Furthermore, the upper and lower ends of the annular protrusion are respectively provided with limiting protrusions surrounding the annular protrusion, and the upper cover ring and the lower cover ring are partially embedded between the limiting protrusions and the connecting ring.

[0011] Furthermore, the cross section of the limiting protrusion is a rectangle or an inverted trapezoid.

[0012] Furthermore, a convex edge is provided on the outer edge of the lower end of the lower cover ring, and the convex edge is used to assist the sealing ring in fixing on the battery.

[0013] Furthermore, the cross section of the upper end of the upper cover ring is arc-shaped.

[0014] Furthermore, the material of the spacer is non-combustible material.

[0015] Furthermore, the connecting ring is made of high-temperature resistant and flame-retardant silicone.

[0016] After adopting the above technical solution, the utility model has the following beneficial effects:

[0017] 1. The utility model uses high-temperature resistant flame-retardant silicone as the main material of the connecting ring and combines it with a spacer made of non-combustible material, so that the sealing ring can maintain its structural integrity in a high-temperature environment, effectively prevent the spread of flames, and improve the safety of the battery system.

[0018] 2. The spacer and the connecting ring of the utility model are provided with an upper cover ring and a lower cover ring which are squeezed into the gap between the products, thereby reducing the bite damage of the connecting ring and increasing the service life of the connecting ring.

[0019] 3. Although the utility model adopts high-level flame retardant materials, the design takes into account the efficient use of materials and reduces the frequency of replacement. In the long run, the utility model can save costs for enterprises and improve economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
