Embodiment 1

[0028] A ring clamp synchronous fastening device, such as figure 1 As shown, it includes two semicircular clamps 2 that cooperate with each other, buckles, bases, and linear motion devices. Buckles are respectively provided at the two ends of adjacent semicircular clamps 2, and bases are provided between adjacent buckles. The base is flexibly and tightly attached to the fastening part 1 , and a linear motion device is vertically arranged on the base, and both sides of the linear motion device are respectively connected to buckles through flexible belts 8 .

[0029] During the use of the present invention, the linear motion device drives the flexible belts 8 at both ends to reciprocate along a straight line to loosen or tighten the buckle, thereby realizing the fastening of the semicircular clamp 2 . Synchronous fastening of the ring clamp is realized by synchronously driving the linear motion of the flexible belts 8 on both sides of the linear motion device. The invention sol...

Embodiment 2

[0031] This embodiment is optimized on the basis of embodiment 1, such as figure 2 As shown, the buckle includes a spacer 5 and a lock 3, one side of the spacer 5 is provided with a profile that abuts against the semicircular clamp 2, and the two ends of the spacer 5 are respectively connected to the lock through a shaft. buckle 3, the other end of the lock buckle 3 is connected with the linear motion device through a flexible strap 8. The two ends of adjacent semicircular clamps 2 are respectively connected by fastening bolts 6 , and sliding holes are provided on the pads 5 corresponding to the fastening bolts 6 . The two ends of the spacer 5 are respectively provided with pin holes, and are connected with the latch 3 through a latch. The invention can realize the synchronous tightening of the ring clamp, avoid the rotation displacement deviation in the installation process of the ring clamp, and ensure the installation accuracy of the ring clamp.

Abstract

The invention discloses an annular hoop synchronous fastening device which comprises two semicircular hoops matched with each other, buckles, a base and a linear motion device, the buckles are arranged at the joints of the two ends of the adjacent semicircular hoops respectively, the base is arranged between the adjacent buckles, and the base is flexibly and tightly attached to a fastening part. The linear motion device is vertically arranged on the base, and the two sides of the linear motion device are connected with the buckles through flexible bridles respectively. The problem that the hoop installation precision is poor since rotating deviation is likely to happen in a traditional asynchronous installation fastening mode is solved, a hoop can be fastened synchronously, rotating deviation of the hoop in the installation process is reduced, and the hoop installation precision is improved.

Description

technical field [0001] The invention belongs to the technical field of fastening devices, and in particular relates to a synchronous fastening device for ring clamps. Background technique [0002] As a reliable connection method for fixing wire harnesses, pipelines and components, ring clamps have been widely used at present. Aircraft, spacecraft, ships, and vehicles all involve the assembly of a large number of ring clamps. Common ring clamp connection methods are bolt connection, thread connection, quick release buckle connection and so on. Bolted connection and threaded connection are mainly to set fastening points at the connection of two semicircular clamps, and use manual or automatic tools to tighten the bolts or threads, so as to realize the fastening of the clamps. The quick-release snap connection only has a fastening point at one end, and the other end is generally a shaft connection. Quick-release buckle connections are mainly used in areas that require freque...
