Problems solved by technology
[0005] The invention can solve the problem that the existing corrugated pipes cannot support the inner wall of the pipe when they are connected, and the corrugated pipes are bent, deformed or even damaged when they are stressed, which affects the use of the corrugated pipes. Moreover, when the existing corrugated pipes are connected, Poor connection effect, inconvenient installation and disassembly, poor sealing performance after connection, easy to enter sewage, humid air, etc. inside the corrugated pipe, and easily damage the internal equipment of the pipe, etc.

Embodiment Construction
[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0027] like Figure 1 to Figure 4 As shown, a mechanical metal fastener includes a fixed frame 1 and a fastening device 2, the fixed frame 1 is a ring structure, two fastening devices 2 are symmetrically arranged on the fixed frame 1, and the two fastening devices 2 are installed on the left and right sides of the fixed frame 1 respectively.
[0028] The fixed frame 1 includes a fixed ring 11, an inner support cylinder 12, a pressing mechanism 13 and a snap-in groove 14. The inner support cylinder 12 is a ring-shaped structure, and the outer middle of the inner support cylinder 12 is fixedly installed with a fixed ring. 11. The connection between the fixed ring 11 and the inner support cylinder 12 is provided with a clamping groove 14, and the fixe...

The invention relates to a mechanical metal fastener. The mechanical metal fastener comprises a fixing frame and fastening devices, wherein the fixing frame is of an annular structure, the two fastening devices are symmetrically arranged on the fixing frame, and the two fastening devices are correspondingly arranged on the left side and the right side of the fixing frame. According to the mechanical metal fastener, the problems that when an existing corrugated pipe is connected, the inner wall of a pipeline cannot be supported, bending deformation and even damage are caused when the corrugatedpipe is stressed, then the use of the corrugated pipe is influenced, the connection effect is poor when the existing corrugated pipe is connected, assembly and disassembly are inconvenient, the sealing performance is poor after connection, dirty water, moist air and the like are prone to enter the interior of the corrugated pipe, and then the internal equipment of the pipeline are prone to damagecan be solved.
Description
technical field [0001] The invention relates to the field of metal fasteners, in particular to a mechanical metal fastener. Background technique [0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used. They are the most widely used mechanical basic fasteners. The clamp is a kind of basic fastener. The clamp is a connecting device for connecting grooved pipe fittings, valves and pipeline fittings. sheet, rubber, silicone and PTFE. The clamp has good performance, high sealing degree and easy installation. When connecting bellows, clamps are usually used for sealed connection. [0003] At present, the existing clamps usually have the following defects when connecting the bellows: 1. When the existing bellows are connected, they cannot support the inner wall of the pipeline, and the bellows will be bent and deformed when the force is applied, or even 2. When the existing bellows are connected, the connection effect is poor, the in...
