Abstract
The utility model discloses a simple quick coupling structure. The simple quick coupling structure comprises a rear connecting tube and a front connecting tube, wherein the rear connecting tube sleeves the front connecting tube; a joint is integrally arranged at the front end of the rear connecting tube; the diameter of an inner hole of the joint is greater than that of the rear connecting tube; a slot is formed in the bottom of the joint; a left positioning hole and a right positioning hole are formed in the top of the joint; a positioning piece and a positioning button which are matched with the left positioning hole and the right positioning hole are arranged on the front connecting tube; a locking clamp sleeves the periphery of the rear connecting tube and is provided with a first positioning hole and a second positioning hole which are opposite to the left positioning hole and the right positioning hole; the lower portion of the locking clamp is provided with a bolt which transversely penetrates in the locking clamp; and a locking trigger sleeves the front end of the bolt. The simple quick coupling structure is simple in structure and convenient to assemble or disassemble and can be arranged quickly; mounted pipe fittings are matched with one another tightly, and do not loose easily; and the service lives of the pipe fittings and the joint are long.
Description
Technical field
The utility model belongs to pipe joint field, is specifically related to a kind of easy quick coupling structure.
Background technique
Along with the development of pipe fitting, be penetrated into every field, be wherein used on garden instrument and also become universal phenomenon, as grass-mowing machine, lawn machine, snowplow, branches of tall trees all-purpose instrument etc.; Due to the regulation of installation dimensions, and the size of the pipe that makes of easy to operate demand has certain length; Therefore increased greatly the Package size of machine, in order to reduce a lot of manufacturers of Package size by separately two to three sections of connecting tubes; In prior art, the joint of connecting tube adopts knob lock locking structure substantially, and connecting tube mostly is metallic material, needs very large power when clamping, and knob lock locking structure can be because of locking effort, and dismounting is relatively wasted time and energy.
