Description

Mounting flange convenient to use Technical Field The utility model relates to the technical field of flanges, in particular to a flange convenient to install. Background Flanges, also called flange flanges, are parts of the shaft-to-shaft connection, typically for connection between pipe ends, and also for connection between two devices, for use on equipment ports. As chinese patent CN222416507U discloses a flange convenient to installation, including flange body, equiangular flange groove and the rubber butt joint section of thick bamboo that is used for connecting of seting up in flange body edge, rubber seal sleeve peg graft in the inside of flange body, and rubber seal sleeve's surface cover is equipped with the sealing washer to the sealing washer closely laminates between flange body and rubber butt joint section of thick bamboo, locking mechanism symmetry sets up in connecting screw's left and right sides, and locking mechanism is used for locking spacing to fixation nut. When using flange to connect pipe-line system, fix through using a plurality of bolts with two ring flanges, the centre installs sealing washer additional and realizes the connection and the sealing of pipeline, however, in the actual installation, there are a great deal of inconvenience in current flange installation, when aiming at the bolt hole, because the ring flange is heavier, manual operation is difficult to accurate alignment, not only consume a large amount of time and manpower, still appear the deviation easily, lead to the installation effectiveness low, secondly, singly lean on the nut to fix, lead to the tightness after the flange installation poor. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides a convenient mounting flange. In order to achieve the purpose, the flange convenient to install comprises a flange assembly, wherein the flange assembly comprises two oppositely arranged flange plates, a plurality of through holes are formed in one annular array of one side of each flange plate in a penetrating mode, a plurality of guide posts are uniformly arranged on one side edge of one flange plate, which is close to the other flange plate, of each flange plate, guide holes are formed in the positions, corresponding to the guide posts, of the other flange plate, a plurality of clamping grooves are uniformly formed in the outer edges of the opposite sides of the two flange plates, a plurality of fixing assemblies are correspondingly arranged on the flange plates in positions, each fixing assembly comprises a fixing plate and a screw rod, two side plates are symmetrically welded at two ends of the fixing plate, clamping blocks are fixedly arranged at the opposite sides of the two side plates, one end of each clamping block is connected with each clamping groove in a penetrating mode, two ends of each screw rod are spliced with the through holes, and two ends of each screw rod penetrate through the two side mounting holes and are in threaded connection with threaded rings.
