Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is suitable for gardens Quick coupling device mechanically.
To achieve the goals above, the utility model uses following technical solution:
A kind of quick coupling device suitable on graden machine, including the first straight tube, outer sleeve and the second straight tube, it is described The inside of first straight tube sets third straight tube, and one end of third straight tube is truncated cone-shaped structure, and the outer wall of third straight tube and first is directly The inner wall of pipe welds, and is welded with the first fixed ring on the outer wall of the first straight tube, the second fixation is welded on the outer wall of the second straight tube Ring, the first straight tube be located at the inside of outer sleeve, and outer sleeve is internally provided with the first rubber gasket, SW with outside ring and bullet Spring, between the first rubber gasket and spring, spring is set SW with outside ring close to the first fixed ring, one end of outer sleeve There is internal thread, the second straight tube is located at the inside of the first straight tube, and the second straight tube is sleeved on one end of third straight tube frustum cone structure, institute It states outer sleeve and sets female side equipped with cored screw, cored screw is equipped with the second rubber gasket.
Preferably, the cored screw is sleeved on the second straight tube, and cored screw is threadedly coupled with outer sleeve.
Preferably, the vertical tangent plane of first straight tube and the second straight tube is rectangular configuration, and the first straight tube is located at spring It is internal.
Preferably, the described one end of second straight tube far from the first straight tube is equipped with internal thread.
Preferably, the described one end of first straight tube far from the second straight tube is equipped with external screw thread.
In the utility model, fixed by outer sleeve, the first rubber sheet gasket, the second rubber sheet gasket, the first fixed ring, second Ring, third straight tube and cored screw carry out cooperation so that the first straight tube and the second straight tube are quickly connected so that one whole Long water pipe can be changed by the device and is formed by connecting at multiple short tubes so that pipeline is when by breakage, it is only necessary to breakage Short tube replaced, such device is not only simple in structure, easy to operate, while having saved replacement cost.
Description of the drawings
Fig. 1 be the utility model proposes a kind of structural schematic diagram suitable for the quick coupling device on graden machine;
Fig. 2 be the utility model proposes a kind of structure partial signal suitable for the quick coupling device on graden machine Figure.
In figure:1 first straight tube, 2 outer sleeves, 3 first rubber gaskets, 4 springs, 5 first fixed rings, 6 second fixed rings, 7 second straight tubes, 8 cored screws, 9 third straight tubes, 10 metals are often around gasket.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.
Referring to Fig.1-2, a kind of quick coupling device suitable on graden machine, including the first straight tube 1,2 and of outer sleeve Second straight tube 7, the inside of the first straight tube 1 set third straight tube 9, and one end of third straight tube 9 is truncated cone-shaped structure, and third straight tube 9 Outer wall and the inner wall of the first straight tube 1 weld, be welded with the first fixed ring 5 on the outer wall of the first straight tube 1, the second straight tube 7 it is outer It is welded with the second fixed ring 6 on wall, the first straight tube 1 is located at the inside of outer sleeve 2, and outer sleeve 2 is internally provided with the first rubber Gasket 3, SW with outside ring 10 and spring 4, SW with outside ring 10 is between the first rubber gasket 3 and spring 4, bullet For spring 4 close to the first fixed ring 5, one end of outer sleeve 2 is equipped with internal thread, and the second straight tube 7 is located at the inside of the first straight tube 1, and the Two straight tubes 7 are sleeved on one end of 9 frustum cone structure of third straight tube, and outer sleeve 2 sets female side and is equipped with cored screw 8, empty Heart screw 8 is equipped with the second rubber gasket.
Cored screw 8 is sleeved on the second straight tube 7, and cored screw 8 is threadedly coupled with outer sleeve 2, the first straight tube 1 and second The vertical tangent plane of straight tube 7 is rectangular configuration, and the first straight tube 1 is located at the inside of spring 4, the second straight tube 7 far from the first straight tube 1 one End is equipped with internal thread, and the one end of the first straight tube 1 far from the second straight tube 7 is equipped with external screw thread.
Operation principle:The first straight tube 1 is stretched into from outer sleeve 2 with female one end with externally threaded one end first The inside of outer sleeve 2, while the second straight tube 7 being inserted into the inside of a straight tube 1, so that one end of third straight tube 9 is caught in the The inside of two straight tubes 7, then cored screw 8 is sleeved on the second straight tube 7 so that cored screw 7 is threadedly coupled with same cross of outer sleeve 6 It tightens, spring 4 is compressed in rundown process so that the first rubber sheet gasket 3 and SW with outside ring 10 are with outer sleeve 2 far from hollow One end close adhesion of screw 8, while second the second straight tube of rubber seal pair 7 and 8 junction of cored screw are sealed, this Sample makes two pipes be quickly connected by outer sleeve 2 and cored screw 8, and such device connects more short tubes It connects so that water pipe only needs to replace damaged portion in breakage, has both conveniently had saving economical.
