Description

Optical cable connector box convenient for secondary opening Technical Field The embodiment of the disclosure relates to the technical field related to optical cable splice boxes, in particular to an optical cable splice box convenient for secondary opening. Background In the maintenance and upgrade process of the optical cable communication network, the optical cable connector box is used as a key component for connecting and protecting the optical cable, and often needs to perform secondary opening operation, such as newly-added optical cable access, fault investigation or line adjustment. However, conventional cable splice enclosures commonly employ a large number of screw-fixed structural designs, which expose significant drawbacks during secondary opening, severely impacting maintenance efficiency and possibly leading to equipment damage. In the prior art, an upper cover and a base of an optical cable connector box are usually fastened through a plurality of groups of screws, and each group of screws needs to be unscrewed one by one to open the box body. The process is time-consuming and labor-consuming, and particularly in field operation or overhead operation scenes, operators need to carry various tools, so that the operation difficulty and the safety risk are increased. For example, in cold weather or complex terrain, the screw may be difficult to screw due to rust or forced deformation, even if the screw slips, breaks, etc., further extending maintenance time. In addition, frequent screw disassembly can lead to screw wear, reduces the leakproofness and the structural stability of joint box, probably causes the problem such as steam invasion, dust entering, influences the long-term reliable operation of optical cable. More importantly, the structure of a large number of screw fixation easily causes the damage of the joint box body when the joint box is opened for the second time. In the traditional design, the plastic shell around the screw hole bears the extrusion stress for a long time, and after multiple times of disassembly, the plastic shell can be cracked and deformed, so that the sealing of the box body is invalid. For example, in an old communication line requiring a plurality of maintenance, the case of replacing a junction box due to the damage of a screw fixing structure is frequently used, not only increasing maintenance costs, but also possibly causing temporary interruption of communication services due to the interruption of an optical cable during replacement. Along with the expansion of the communication network scale and the improvement of intelligent operation and maintenance requirements, higher requirements are put forward on the convenient maintenance performance of the optical connector box. The traditional screw fixing mode is difficult to adapt to the industry requirements of quick response and high-efficiency maintenance, and the development of a novel optical cable joint box which is free of a large number of screw fixing, convenient to open for the second time and difficult to damage is urgent. Through improving connection structure, realize opening and shutting fast and used repeatedly, have important realistic meaning to reduce maintenance cost, promote the network reliability, ensure communication service's continuity. Disclosure of utility model In order to overcome the defects, the embodiment of the disclosure provides a convenient secondary opening type optical cable joint box, which solves the technical problem that a large number of screw-fixed structures in the prior art easily cause the damage of a joint box body when being opened secondarily, and the joint box body possibly cracks and deforms after being disassembled for many times, so that the sealing of the box body is invalid. According to one aspect, at least one embodiment of the present disclosure provides a convenient secondary opening cable closure comprising: the auxiliary box is connected to the main box; A pair of raised strips and a fixed tightening assembly, wherein the raised strips are arranged at the bottom of the main box, the fixed tightening assembly is arranged on the main box and the auxiliary box; The fixing sleeve tightening assembly comprises a pair of clamping grooves, the clamping grooves are respectively formed in the two opposite ends of the main box and the two opposite ends of the auxiliary box, the two sides of the main box and the two sides of the auxiliary box are respectively sleeved with a fixing sleeve frame, and the fixing sleeve frames are sleeved in the clamping grooves. As a further technical scheme, all movable sleeves are equipped with the movable column in the sand grip both ends, the transmission chamber has been seted up to the movable column inside, the movable sleeve is connected with the sliding block in the transmission chamber, sliding block one end is connected with the pull rod through the round pin axle rotation. As a further technical scheme, the outside co
