[0021] The technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of the utility model protection.

[0022] Please refer to Figures 1-6The utility model provides a technical scheme: a quick connection rubber hose, including rubber hose 1, the opposite end of rubber hose 1 is fixedly installed with plug 11 and connecting head 12 respectively, and mutually inserts and connects, the surface of plug 11 is fixedly connected with limit rod 111 in pairs, the surface of connecting head 12 is opened in pairs with arc slide rail 121, and arc slide rail 121 side wall is opened with arc groove 124, the inner chamber of arc groove 124 is rotatably connected with rotating clamping block 123 through pin shaft 122, limit rod 111 is slidably connected in arc slide rail 121, and presses and supports rotating clamping block 123, the surface of rotating clamping block 123 is clamped with limit rod 111, and limit rod 111 is extruded rotating clamping block 123 again and is positioned by rotating clamping block 123, forms the connection mode of clamping.

[0023] The surface of rotating clamping block 123 and the inner chamber of arc groove 124 mutually fit, so when rotating clamping block 123 rotates, due to the relationship of fitting with the inner chamber of arc groove 124, can limit rotating clamping block 123, reach the effect of firmness, the side of rotating clamping block 123 and the inner wall of arc groove 124 are all opened with mounting hole 125, and spring 127 is fixedly installed between mounting hole 125, and rotating clamping block 123 has extrusion force by the elastic force of spring 127.

[0024] The outer side of rotating clamping block 123 is arc irregular shape, and limit rod 111 extrudes rotating clamping block 123 to rotate conveniently.

[0025] The surface of rotating clamping block 123 is opened with recess point 126, and the tool of tweezers is inserted into recess point 126 and is broken rotating clamping block 123, to facilitate subsequent disassembly.

[0026] When working or using, first, plug 11 and connecting head 12 are fixedly installed on the end of rubber hose 1 needing to be connected, then limit rod 111 is aligned with arc slide rail 121 port and is inserted, so that limit rod 111 will slide along arc slide rail 121, at the same time, plug 11 will be inserted into connecting head 12, and limit rod 111 will extrude rotating clamping block 123 when sliding, and rotating clamping block 123 is extruded into the inner chamber of arc groove 124 by the rotating connection of pin shaft 122, so that spring 127 connected in mounting hole 125 will also retract, until limit rod 111 completely enters the innermost part of arc slide rail 121, so that limit rod 111 will not press rotating clamping block 123 again, and therefore, under the elastic force of spring 127, rotating clamping block 123 will reset, so that rotating clamping block 123 will fasten and clamp limit rod 111, complete connection, the extrusion clamping of the elastic force of rotating clamping block 123 makes connecting head 12 and plug 11 connect more closely, thereby improving the sealing between connecting head 12 and plug 11, and in addition, in subsequent continuous disassembly, the loosening between connecting head 12 and plug 11 will not be caused by abrasion.

[0027] When it is necessary to disassemble, a tool such as a tweezers is inserted into the groove point 126 and pried outward, so that the rotating block 123 enters the arc-shaped slot 124, so that the limiting rod 111 loses the extrusion clamping force, and at the same time the plug 11 is rotated, so that the limiting rod 111 slides out of the arc-shaped sliding rail 121, and the disassembly is achieved. The disassembly mode is simple and the disassembly efficiency is high.
