Specific embodiment
The enforcement of the tail accessory of adapter is for example shown in Fig. 1 ~ 8：Tail accessory includes anti-falling piece 12, axis along front and back
Jam-packed nut 11 to the sleeve 2 for extending and for spinning on sleeve.Jam-packed nut 11 includes nut body, on nut body
With external screw thread 6, the endoporus rear end of sleeve 2 is set around circumferentially-spaced on the barrel of sleeve with the female thread coordinated with external screw thread
It is equipped with the long guiding hole 8 that two length extend along the longitudinal direction.Anti-falling piece 12 include by made by nylon material with jam-packed nut
The 11 anti-falling piece bodies being rotatably assorted, anti-falling piece body include that what thickness of slab extended along the longitudinal direction slides for being oriented to along the longitudinal direction
Substrate 10 in the dynamic endoporus for loading sleeve, the rear plate face of substrate 10 for by the leading section pushing tow of jam-packed nut, in sleeve 2 in
Be provided with sealing ring 3 and pad 4 on front side of substrate, the periphery of substrate around be provided at circumferentially spaced two respectively with each long guiding hole
Corresponding substrate bumps 9, are provided with substrate projection in the inner side of counterpart substrate projection 9 on substrate and radially produce in sleeve
The deformation groove 15 of deformation, deforms the arc-shaped slot that groove 15 is that axis extends along the longitudinal direction, by the setting for deforming groove so that base
Plate projection 9 can be easier radially to produce elastic deformation, and thus very easily substrate can be assembled in the endoporus of sleeve,
After substrate loads in the endoporus of sleeve, substrate bumps reset and enter in long guiding hole, and long guiding hole has to be used for and base
The raised spacing cooperation of plate to realize the forward and backward hole wall of anti-falling piece and the assembling of sleeve anticreep, by the forward and backward hole wall of long guiding hole with
The spacing cooperation of substrate bumps can prevent anti-falling piece from being deviate from by sleeve in the longitudinal direction.The front end inner peripheral surface of jam-packed nut
It is provided with nut positive stop lug boss 14, the endoporus of jam-packed nut is that front end aperture is little, the shoulder hole structure that rear end aperture is big, spiral shell
Female positive stop lug boss surrounds the aperture section of shoulder hole structure, and anti-falling piece body is included for stretching into the nut screw connection section of jam-packed nut,
In the present embodiment, nut screw connection section includes two endoporus for stretching into nut resiliently overhanged backwards for being arranged at substrate rear end
In elastic cantilever 5, the projecting end of elastic cantilever is provided with 7 nut of anti-falling piece positive stop lug boss on rear side of nut positive stop lug boss
The rear end of positive stop lug boss with for cooperation spacing with anti-falling piece positive stop lug boss limiting the spiral shell of nut body moving limit backwards
Female stop section 13, the cross sectional shape of anti-falling piece positive stop lug boss is circular arc, can so facilitate jam-packed nut to assemble.Figure middle term 1
Expression is arranged at the connector body of tail accessory front end.
The assembling process of the tail accessory of this adapter is：By sealing ring and pad（Single product can not assemble pad）It is suitable
In the secondary endoporus for loading sleeve, then anti-falling piece is encased in the endoporus of sleeve by rear to front, anti-falling piece is in loading procedure
In, substrate bumps are produced elastomeric radial by the barrel top pressure of sleeve, after substrate bumps are moved to long guiding hole position,
Substrate bumps reset and extend in long guiding hole, this completes the assembling of anti-falling piece, and substrate bumps can be along the longitudinal direction
Slide in long guiding hole, while not affecting the relative rotation between jam-packed nut and sleeve, finally load jam-packed nut, squeezing
When tight nut court screws direction movement, anti-falling piece positive stop lug boss does not interfere with the normal screwing operations of jam-packed nut, but works as
When jam-packed nut is by departing from sleeve, by the position-limiting action of anti-falling piece positive stop lug boss, jam-packed nut is limited in nut screw connection section
On without the loss that drops, while reducing assembly difficulty, improve efficiency of assembling；Substrate moved forward by jam-packed nut pushing tow with
Sealing ring is compressed, the abrasion between jam-packed nut and pad can also be so avoided, it is ensured that the service life of pad, elastic cantilever
In the endoporus of jam-packed nut, therefore be not in that operator cause jam-packed nut to depart from anti-falling piece because of maloperation
Problem；Nut positive stop lug boss only need to be set on jam-packed nut, and the change to jam-packed nut is less.
In other embodiments of the invention：Anti-falling piece body can be with by the high intensity such as PEI, steel or copper and toughness material
Make；The shape of deformation groove can also be square, circular or other shapes, and the deformation groove on certain substrate can also be without setting, this
When substrate bumps can be deformed by the toughness of itself completely and complete assembling；Substrate can be made up of rigid material,
Now substrate can be replaced by the matrix of block structure or frame structure, and feather key or feather key now can be arranged on matrix
Groove, arranges the guide key groove and feather key being adapted to therewith in the sleeve wall of sleeve, is assembled in sleeve in matrix guiding movement
Afterwards, on the inwall of sleeve, setting other position limiting structures such as jump ring or gland are spacing to carry out to the moving limit backwards of anti-falling piece
To realize that anti-falling piece and the anticreep of sleeve coordinate；Certainly anti-falling piece can also fixing assembling on sleeve, now sleeve and anticreep
Fixed structure between part realizes that anti-falling piece and the anticreep of sleeve coordinate；Nut positive stop lug boss can also be arranged at jam-packed nut
On outer peripheral face, now elastic cantilever can be arranged in the periphery of jam-packed nut, and anti-falling piece positive stop lug boss is arranged at elastic cantilever
Inner side；Certainly elastic cantilever can also be replaced by the stiff cantilevers with elastic deformability, and now whole anti-falling piece can be with
Make Split type structure, such as anti-falling piece include two parts up and down that split is arranged, anti-falling piece positive stop lug boss be respectively arranged in
After on rear side of nut positive stop lug boss, then upper and lower two parts anti-falling piece is assembled together, now nut screw connection section may not be
Spaced cantilever design, such as set shape structure or frame structure；The number of substrate bumps and elastic cantilever can be with root
Selected according to needs, such as three, four or other numbers；Anti-falling piece spacing preiection can be fixed on bonding or be spirally connected
On correspondence elastic cantilever；Anti-falling piece body can also be assemblied on the outside of sleeve, and now jam-packed nut directly can be carried out to pad
Pushing tow；The cross sectional shape of anti-falling piece positive stop lug boss can also be square, now during assembling jam-packed nut, can be pressed with handss
Elastic cantilever operation.
The enforcement of anti-falling piece is for example shown in Fig. 5 ~ 8：The concrete structure of anti-falling piece and institute in above-mentioned each tail accessory embodiment
The anti-falling piece stated is identical, will not be described in detail herein.
