Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, a specific embodiment of the present invention is an easy-to-mount connecting member, including an upper fixing seat 1, a lower fixing seat 2, and a connecting rod 3, wherein cavities are respectively disposed in the middle portions of the upper fixing seat 1 and the lower fixing seat 2, an elastic member 4 is disposed in the lower fixing seat 2, a locking nut 5 is disposed on the elastic member 4, the locking nut 5 is fixed on the middle upper portion of the lower fixing seat 2, the tail end of the connecting rod 3 is connected to the upper fixing seat 1, the front end of the connecting rod 3 is of a tapered platform structure, and the front end of the connecting rod 3 can be inserted into the lower fixing seat 2 and locked and fixed;
the locking nut 5 still is provided with buckle spare 6 with between the 2 middle parts of lower fixing base, buckle spare 6 is formed by two or more arc cramps 601 combination, the peripheral elastic annular gum cover 7 of parcel of arc cramp 601, the height that highly is less than or equal to arc cramp 601 of the inside cavity of annular gum cover 7, the cross section of annular gum cover 7 is U type structure, the front end of connecting rod 3 can insert in buckle spare 6, buckle spare 6 is propped open in annular gum cover 7.
When the device is used, the tail end of the connecting rod 3 is of a cylindrical structure, the tail end of the connecting rod 3 is in spiral connection with the upper fixing seat 1, and the rear end of the connecting rod 3 is screwed into the cavity of the upper fixing seat 1; then embedding the arc-shaped buckle piece 601 into the annular rubber sleeve 7 to form a buckle piece 6 integrally, placing the elastic piece 4 into the lower fixed seat 2, placing the buckle piece 6 above the elastic piece 4, placing the buckle piece 6 between the elastic piece 4 and the locking nut 5, and then screwing the locking nut 5 into the lower fixed seat 2 to fix the buckle piece 6, namely completing the preparation work; during the equipment, insert fixing base 2 down with connecting rod 3, the front end of connecting rod 3 passes buckle 6 and extrudees arc cramp 601 and opens, and the toper platform structure of connecting rod 3 front end passes back arc cramp 601 completely and contracts and hold the connecting rod rear end tightly, complete equipment promptly.
For convenience of use, the fastener 6 is composed of 4 arc-shaped fastening pieces 601. The three to four arc-shaped buckling pieces have the advantages of optimal opening and closing effect, more stable clamping and convenient and quick installation.
