TECHNICAL FIELD
[0001] The utility model relates to the field of low voltage distribution cabinet, concretely to a soft and hard composite drainable type sealing structure for low voltage distribution cabinet. BACKGROUND
[0002] The role of the sealing strip in the low voltage distribution cabinet is to seal and prevent dust from entering the interior of the distribution cabinet. Excessive dust can affect the performance and state of the internal equipment of the distribution cabinet, such as causing short circuits or affecting heat dissipation. The sealing strip is installed on the door edge, which can effectively prevent dust from entering the interior of the cabinet, ensuring the cleanliness of the interior of the cabinet and the good operation of the equipment. Shock absorption: when the distribution cabinet is subjected to slight vibration, the sealing strip can act as a buffer to protect the internal components from vibration and prolong the service life of the equipment. Waterproof and moisture-proof: in some special environments, such as high humidity or places where water may accumulate, the sealing strip can prevent water vapor from entering the distribution cabinet, preventing the internal components from being damaged by moisture. Sound insulation and heat insulation: although the sound insulation and heat insulation requirements of the low voltage distribution cabinet are not as high as those of some special equipment, the sealing strip can still reduce noise transmission and provide some heat insulation effect.
[0003] Rubber sealing strip is a common sealing material, which has good elasticity and weather resistance, and is suitable for various scenes such as waterproof, dustproof and sound insulation. Common types of rubber include nitrile rubber, propylene rubber, EPDM (ethylene propylene rubber) and others. The advantages of rubber sealing strip include: good elasticity and softness. Good durability, can resist some physical wear and tear and environmental influences.
[0004] Silicone sealing strip has excellent high temperature resistance, chemical resistance and flexibility, and is commonly used in high temperature environments or special chemical environments. Its advantages include: excellent high temperature resistance, not easy to age. Good weather resistance, good resistance to ultraviolet light and some chemicals. Good sealing performance, can prevent water and dust.
[0005] In summary, the existing technology has many drawbacks, which are summarized as follows:
