Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Embodiment 1
As shown in Figure 1, a kind of chuck formula link, comprise attaching nut 1, there is bottom described attaching nut 1 pitman 2 in strip, in described attaching nut 1, be bolted with a swivel nut 3, the described cylindrical swivel nut connecting end 4 in swivel nut 3 one end, form several cards 5 after the other end bifurcated, between the card 5 that every two panels is adjacent, there is gap, to outstanding away from the direction of swivel nut 3 shaft axis thus make the outer surface of card 5 form cambered surface in the middle part of card 5, make card 5 have elasticity, be easy to draw in.The quantity of card 5, more than 2, can be preferably 3 or is greater than 3, and as shown in Figure 3, the quantity of card is 4, and as shown in Figure 4, the quantity of card is 6.In described swivel nut 3, there is the passage that inserted link 6 can be allowed to insert, when inserted link 6 is inserted in swivel nut 3, described inserted link 6 and swivel nut 3 are by chuck mechanism 10 snap-fit engagement thus stops inserted link 6 to depart from attaching nut 1, described inserted link 6 is bolted with inserted link locating piece 7 that an energy axially moves up and down along inserted link and mobile described in inserted link locating piece 7 inserted link locating piece 7 and swivel nut 3 can be made to be close to.
Again shown in composition graphs 2, Fig. 5 and Fig. 6, swivel nut 3 has away from the end of card 5 positioning retainer ring 9 that external diameter is greater than attaching nut 1 internal diameter, and described swivel nut connecting end 4 outer wall has outside thread.The shaft axis of pitman 2, swivel nut 3 and inserted link 6 overlaps, and described pitman 2 has outside thread or internal thread, and described inserted link 6 having a cross section is polygonal spanner fixing part 20.
Chuck mechanism 10 comprises the chuck 11 be arranged on inserted link 6, when inserted link 6 is inserted in swivel nut 3, described card 5 end is moved to the direction away from swivel nut 3 shaft axis, when inserted link 6 continues to insert and chuck 11 is positioned at swivel nut 3 outside, card 5 end is moved near swivel nut 3 direction of axis line thus card 5 end is stuck in chuck 11.
In the present embodiment, inserted link locating piece 7 comprises gland nut 8, described gland nut and inserted link 6 threaded.Rotate gland nut 8 also when gland nut 8 is fitted with swivel nut connecting end 4, be rotated further, can pull inserted link 6, thus make chuck 11 hold out against card 5 end, that is, gland nut 8 plays location regulating action
As shown in Figure 5, when inserted link 6 is inserted in swivel nut 3 and after forming clamping, plunger body 12 is positioned at outside swivel nut 3, and clamping joint 13 is positioned at swivel nut 3.It will be appreciated by those skilled in the art that the diameter of clamping joint 13 biggest place must not be greater than the internal diameter of swivel nut 3, the edge of chuck 11 then should be positioned at outside card 5 end, and this belongs to those skilled in the art and adjusts for the routine of size.
Inserted link 6 comprises plunger body 12 and is positioned at the clamping joint 13 of plunger body 12 end, the described joint of chuck 11 between plunger body 12 and clamping joint 13.Preferably, clamping joint 13 outer wall has smooth cambered surface and tapered.
Plunger body 12 is that sectional area is toward the diminishing circular cone 21 in clamping joint 13 direction near one end of clamping joint 13.When card 5 and chuck 11 clamping, described circular cone 21 outer wall and card 5 inwall are fitted, and circular cone 21 also plays positioning action, makes snap-fit engagement tightr.
Clamping joint 13 is tapered, chuck 11 has one and is ring and the chuck baffle ring 14 be connected with clamping joint 13, described plunger body 12, the annular slot 15 that between chuck 11 clamping joint 13 and chuck baffle ring 14, formation is inserted for card 5 end.Chuck baffle ring 14 plays barrier effect, prevents card 5 from departing from chuck 11, and that is, card 5 end can be fixed in annular slot 15, thus improves snap effect, more reliable and more stable when being link connection.
The working principle of the present embodiment is: after swivel nut 3 and attaching nut 1 threaded, inserted link 6 is inserted in swivel nut 3 and makes clamping joint 13 extend card 5 end, card 5 end is stuck in chuck 11 place, screws tight gland nut 8 and card 5 end is held out against with chuck 11 coordinate, and can realize connecting.
Those skilled in the art are to be understood that, pitman 2 can be reinforcing bar, steel strand, rod iron, chemical industry section bar, carbon fiber rod etc., shape then can be various, can be hollow, solid, outer wall is smooth, outer wall is by concavo-convex etc., pitman can be used for connecting precast pile, metope or other structures, facilitates the use of this link.
This link is used for the connection between two objects, and wherein attaching nut 1 connects an object, and swivel nut 3 and attaching nut 1 are spirally connected, inserted link 6 connects another object, when inserted link 6 is inserted into the connection that can realize two objects in swivel nut 3, easy to assembly, easy to connect, firmly.Above-mentioned object can be precast pile, metope, building block, rail etc., it will be appreciated by those skilled in the art that all the other need the object connected also can connect with this link.
Embodiment 2
The present embodiment is substantially identical with working principle with the structure of embodiment 1, difference is, as Figure 7-8, chuck mechanism 10 comprises and is arranged on attaching nut 1 inwall and in the stepped part 16 of ring, described card 5 end outwardly forms card article 17, described inserted link 6 end has an Expandable strip 18 in round platform taper, when Expandable strip 18 moves toward the direction of attaching nut 1 oral area, described card 5 moves to the direction away from swivel nut 3 shaft axis and makes card article 17 and stepped part 16 snap-fit engagement.
Card article 17 top is plane, and card article 17 inner and outer wall has inclined-plane, and described Expandable strip 18 outer wall and card article 17 inwall match.Card 5 has a district 19 that steps down caved inward between swivel nut connecting end 4 and card article 17.
The working principle of the present embodiment is: be enclosed within by swivel nut 3 on inserted link 6, Expandable strip 18 is formed with card 5 inwall and coordinates, gland nut 8 is screwed onto on inserted link 6, swivel nut 3 is spirally connected with attaching nut 1, fixes inserted link 6 with spanner or other fastening piece, rotate gland nut 8, be rotated further when gland nut 8 is connected nut 1, it is inner that Expandable strip 18 is up manoeuvred into swivel nut 3, and card 5 toward extending out, can form clamping under Expandable strip 18 acts on when card article 17 extends to stepped part 16.When card article 17 is formed fastening with attaching nut 1 inwall by needs further, only need to carry inserted link 6 toward pull-up and make card article 17 upper surface be adjacent to stepped part 16, be rotated further gland nut 8 to card article 17 outer wall be close to attaching nut 1 inwall can be formed expand fixing.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
