Specific embodiment
The present invention is described further below in conjunction with attached drawing:
Embodiment one:
The present embodiment includes oil pipe ontology 1 and box cupling, and two oil pipe ontologies 1 are connected to a box cupling by tubing round thread
On.The above are universal architectures in the prior art, and details are not described herein.
Axially extending square shaped teeth is provided on the end face of oil pipe ontology 1, the structure of the box cupling includes shell, installation
Square shaped teeth on the intracorporal anti-down buckle mechanism of shell and key, the oil pipe ontology 1 is connect with the anti-down buckle mechanism, is prevented
Back-off mechanism can prevent reversed (move back and buckle direction) relative rotation of two oil pipe ontologies 1 up and down, to realize preventing covering upside down function.
Anti-down buckle mechanism, structure include upper fluted disc 9, outer ring 8, inner ring 6 and lower tooth disk 3, the two sides up and down of upper fluted disc 9,
The two sides up and down of the upside of outer ring 8, the downside of inner ring 6 and lower tooth disk 3 are also equipped with square shaped teeth, rectangular on the upside of upper fluted disc 9
The rectangular tooth engagement for 1 lower end of oil pipe ontology that tooth is connect with by box cupling connects, the square shaped teeth and outer ring 8 of upper 9 downside of fluted disc
The rectangular tooth engagement of upside connects, and the square shaped teeth of 6 downside of inner ring is connect with the rectangular tooth engagement of 3 upside of lower tooth disk, under lower tooth disk 3
The rectangular tooth engagement for another 1 upper end of oil pipe ontology that the square shaped teeth of side is connect with by box cupling connects, and the upside of the inner ring 6 is set
It is equipped with rotary table, is uniformly arranged on the cylindrical surface on the outside of rotary table there are four gap, the downside of the outer ring 8 is provided with and the rotary table
The seam allowance that matches of outer diameter, the rotary table is inserted in the seam allowance, and forms wedge shape in the opening position after grafting
Gap 17, in the wedge gap 17, the biggish one end in gap is provided with roller 13 and spring A16, and spring A16 makes roller 13
The movement tendency close to the tip of wedge gap 17 is kept, fluted disc can be made by being provided between the upper fluted disc 9 and outer ring 8
9 and the spring B 11 that is located remotely from each other in the axial direction of outer ring 8, lower tooth can be made by being provided between the lower tooth disk 3 and inner ring 6
The spring C14 that disk 3 and inner ring 6 are located remotely from each other in the axial direction.
To on box cupling when connected pipes ontology 1, the two need to only be tightened by pipe wrench, not had with ordinary operation mode
Difference, thus the present invention have the characteristics that it is easy for installation.Oil tube external thread on an oil pipe ontology 1 located above is to box cupling
During interior screw-in, the lower end of oil pipe ontology 1 touched fluted disc 9 before this, and after rotating by a certain angle by square shaped teeth with
Upper fluted disc 9 engages, and then upper fluted disc 9 is rotated together with together with outer ring 8 with oil pipe ontology 1, on be located below oil pipe ontology 1
Oil tube external thread screwed in into box cupling during, the upper end of oil pipe ontology 1 touched lower tooth disk 3 before this, and certain in rotation
It is engaged by square shaped teeth with lower tooth disk 3 after angle, then lower tooth disk 3 is rotated together with together with inner ring 6 with oil pipe ontology 1, that is,
It says, in oil pipe ontology 1 and box cupling connection procedure, outer ring 8 and inner ring 6 rotate freely relatively.When oil pipe ontology 1 is born and is tightened
When the opposite torque of torque direction, the roller 13 in the wedge gap 17 will be stuck between inner ring 6 and outer ring 8, make inner ring 6
It cannot be relatively rotated in this direction with outer ring 8, to realize preventing covering upside down function.It can be seen that the present invention has mechanism ingenious, design
Novel feature.
The downside of the outer ring 8 and the upside of inner ring 6 carry out axial direction by a position-limitting pin 7 being mounted on shell
Limit, prevents the downward vibration of outer ring 8, while preventing the upward vibration of inner ring 6.
The upper edge of the upper fluted disc 9 and the lower edge of lower tooth disk 3 are provided with step 4, on the shell
It is correspondingly arranged on keyhole 5 with the step 4, the end of the key is provided with work department 18, and work department 18 is by keyhole 5
It is inserted into and extends at the step 4.When needing to separate oil pipe ontology 1 and box cupling, key is extended at step 4 and turns key
Spoon, work department 18 on the key can stir fluted disc 9 and move down, or stirs lower tooth disk 3 and move up, to make oil pipe ontology
1 is detached from the rectangular teeth drive pair that upper fluted disc 9 or lower tooth disk 3 are directly pressed, to make oil pipe ontology 1 that can be freely disassembled.
The shell is split type structure, including upper housing 10 and lower case 2, the two are connected through a screw thread integrally, and
And the locking jackscrew 12 for preventing the thread looseness is provided at the screw thread.It is interior in order to make that split type structure, which is made, in shell
Each part in portion is able to be installed in shell.The advantage of this structure is it is easy to assembly, the disadvantage is that the intensity of shell is poor.
Embodiment two:
The difference between this embodiment and the first embodiment lies in the structure of shell is different.
In the present embodiment, shell is an integral structure, and the upper fluted disc 9, outer ring 8, inner ring 6 and lower tooth disk 3 are
Split type structure, the plane cutting that upper fluted disc 9, outer ring 8, inner ring 6 and lower tooth disk 3 are parallel to each other by two Duis is at eight pieces.After cutting,
Upper fluted disc 9, outer ring 8, inner ring 6 and lower tooth disk 3 can be packed into shell in the unseparated situation of shell.
In actual operation, the cutting position on upper fluted disc 9, outer ring 8 and lower tooth disk 3 does not have specific requirement, but in inner ring 6
Cutting position must propose specific requirement, reason is: when roller 13 plays counteresteer, peace that roller 13 is depended on
Dress matrix can bear very big radial thrust, and after passing through face parallel cut, if wedge gap 17 is completely positioned at each pair of parallel
Between two planes in face, the block in inner ring 6 with gap can be passed to power on the block without gap, and without gap
Block the block with gap can be prevented to move radially, to ensure that the normal work of counteresteer effect.
The upper fluted disc 9, outer ring 8, inner ring 6 and lower tooth disk 3 inside be provided with jump-ring slot, be equipped in jump-ring slot
Wire circlip 15.The main function of wire circlip 15 is the radial vibration for preventing the block between two parallel surfaces, actually steel wire
The power that circlip 15 is born is minimum.
The keyhole 5 being correspondingly arranged on shell with each step 4 at least one, also can be set it is multiple, prevent
The only appearance of Caton phenomenon.
