Abstract
The invention discloses a flexible pipe coupling. The flexible pipe coupling comprises an outer flexible coupling sleeve and an inner flexible coupling sleeve located in the outer flexible coupling sleeve. The outer flexible coupling sleeve and the inner flexible coupling sleeve are both round tubes. The two ends of the outer flexible coupling sleeve are provided with coupling heads in an inserted mode correspondingly. The part, located in the outer flexible coupling sleeve, of each coupling head is provided with sawtooth grooves. The sawtooth grooves include the first sawtooth grooves and the second sawtooth grooves. The first sawtooth grooves are located in the inner walls of the coupling heads. The second sawtooth grooves are located in the outer walls of the coupling heads. The length of the second sawtooth grooves is not less than that of the first sawtooth grooves. The two ends of the inner flexible coupling sleeve are inserted into the two coupling heads correspondingly. A first spring and a second spring are sequentially arranged between the outer flexible coupling sleeve and the inner flexible coupling sleeve in a sleeved mode. The two ends of the first spring are clamped into the first sawtooth grooves of the two coupling heads. The two ends of the second spring are clamped into the second sawtooth grooves of the two coupling heads. The flexible pipe coupling has flexibility, can be applied to turns with angles, especially right-angle turns and can guarantee that an oil way is clear.

Cuff and it is flexible in cuff be pipe, grafting is provided with hoop head respectively at the two ends of the outer cuff of flexibility, and hoop head is positioned at flexible
Part on the inside of outer cuff offers serrated slot, and the serrated slot includes the first serrated slot and the second serrated slot, first saw
Teeth groove is located on the inwall of hoop head, and second serrated slot is located on the outer wall of hoop head, and the length of the second serrated slot is not less than the
One serrated slot, the two ends of the flexible interior cuff are plugged in two hoop heads respectively, between the outer cuff of flexibility and flexible interior cuff
The first spring and second spring are arranged with successively, and the two ends of first spring are connected in the first serrated slot of two hoop heads, institute
The two ends for stating second spring are connected in the second serrated slot of two hoop heads.
Further, the external diameter of the outer cuff of the flexibility is two times of the external diameter of cuff in flexibility.
Further, the outer cuff of the flexibility is made by rubber with the flexible interior cuff, and the hoop head is by rustless steel
Make.
Further, one of them described hoop head is located at the part on the outside of flexible outer cuff and offers external screw thread, Ling Yisuo
State hoop head female thread is offered positioned at the part on the outside of flexible outer cuff.
The present invention provides a kind of flexible pipe box cupling, the pipe box cupling include the outer cuff of flexibility, it is flexible in cuff, two hoop heads, the
Two hoop heads and the first spring and second spring between the outer cuff of flexibility and flexible interior cuff, with flexibility, can adjust,
Having angled turning, especially right angle turn can be suitable for, it is ensured that oil circuit is unobstructed.
Description of the drawings
The present invention is described in further detail below according to drawings and Examples.
Fig. 1 is a kind of structural representation of flexible pipe box cupling of the invention.
In figure：The flexible outer cuffs of 1-；Cuff in 2- is flexible；3- binds round head；The first serrated slots of 4-；The second serrated slots of 5-；6-
