Closure capable of being quickly opened

Abstract

The invention discloses a closure capable of being quickly opened, which comprises a bottom box, a top cover, an inner support, an optical cable reinforced core fixing device and a welding protection disc, wherein a welding protection disc cover plate is arranged above the welding protection disc, the inner support is arranged below, the optical cable reinforced core fixing device is arranged on the inner support, the inner support is located in the bottom box, the bottom box and the top cover are fixed through an elastic buckling structure, the elastic buckling structure is located at two sides and two ends of the closure, the elastic buckling structure comprises locking elastic buckles fixed on the bottom box and locking pull buckles fixed on the top cover, cable incoming holes are arranged at two ends of the bottom box, the inner side walls of the cable incoming holes are provided with optical cable sealing circles, optical cable sealing circle locking nuts and optical cable locking nuts are arranged outside the cable incoming holes, one end of each optical cable sealing circle locking nut is matched with the cable incoming hole through inner thread, and the other end of the optical cable sealing circle locking nut is matched with the optical cable locking nut through outer thread. According to the closure of the invention, both quick opening and sealing reliability can be ensured.

Description

technical field [0001] The invention relates to an optical cable joint box, in particular to a quick opening optical cable joint box. Background technique [0002] With the large-scale construction of optical communication networks, the network is deeply affecting our lives. The deployment of optical fiber networks and the laying and connection of optical cables are extremely important links. Optical cable splice boxes have become an indispensable product for communication construction. [0003] The traditional optical cable splice box has the following disadvantages: 1. The box body is fastened by bolts, which is very inconvenient for construction operation and later maintenance, and the labor cost is high; 2. The seals of the splice box cannot be reused, and every maintenance The seal must be replaced, and the operation is difficult. Some splice box seals can be reused, but the temperature cycle performance of the splice box cannot meet the standard requirements; Note, th...

Problems solved by technology

[0003] The traditional optical cable splice box has the following disadvantages: 1. The box body is fastened by bolts, which is very inconvenient for construction operation and later maintenance, and the labor cost is high; 2. The seals of the splice box cannot be reused, and every maintenance The seal must be replaced, and the operation is difficult. Some splice box seals can be reused, but the temperature cycle performance of the splice box cannot meet the standard requirements; Be careful, the optical cable will be pulled off, which will bring difficulties to the construction; 4. The fixed place where the optical cable enters the nut is easy to loosen when the optical cable is stretched and twisted, and the reliability of the seal cannot be guaranteed.
