Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of grafting clamp-close type connector, including a connection-peg 1 and an attaching nut 2, it is described
The one end of attaching nut 2 is bolted with intermediate nut 3, and intermediate nut 3 is threaded into inside attaching nut 2, and the other end of attaching nut 2 is spirally connected
There is connecting bolt 4, described connection-peg 1 can be inserted into intermediate nut 3 and be connected and fixed with intermediate nut 3.
The length entered by adjusting connecting bolt 4 in attaching nut 2, you can adjust the length of whole connector.
Elastic component 21, packing ring 22 and snap ring are sequentially provided with attaching nut 2 and from the direction of connecting bolt 4 toward connection-peg 1
Component 23, elastic component 21 can be spring or cylindrical spring, the end of described snap ring assemblies 23 and intermediate nut 3 match and
Pushed into by elastic component 21 in the end of intermediate nut 3, when connection-peg 1 is inserted into intermediate nut 3, snap ring assemblies 23 can block
Firmly connection-peg 1 is so that connection-peg 1 connects and fixes with intermediate nut 3, with reference to shown in Fig. 4, if described snap ring assemblies 23 include
Dry along the circumferentially distributed card 24 of annular slot 13, card 24 be quantity more than 2, preferably 4, form the knot of annular
Structure.
Connection-peg 1 includes connection end 11 and inserted terminal 12, and described inserted terminal 12 has what is matched with snap ring assemblies 23
Annular slot 13, after snap ring assemblies 23 are snapped onto in annular slot 13, inserted terminal 12 is stuck fixation, also just and middle screw
Mother 3 realizes clamping.The one end of one end and connecting bolt 4 away from attaching nut 2 of connection-peg 1 away from attaching nut 2 connects respectively
There is bar component 5.In the present embodiment, the jointing nut 52 of connection end 11, connecting bolt 4 also connect a collar nut
52。
As shown in figure 5, bar component 5 includes barred body 51 and the collar nut 52 being connected with the end of barred body 51, it is described
Collar nut 52 there is internal thread, described collar nut 52 and connecting bolt 4 or connection-peg 1 are spirally connected fixation.In barred body 51
Portion is provided with the hollow air flow channel 53 that is axially arranged with along barred body 51, and the described outer wall of barred body 51 is provided with and connected with air flow channel 53
Solarization air cap 54, described air flow channel 53 connection collar nut 52, the side wall of described collar nut 52 is provided with least one
Individual grout hole 55.
As shown in figure 5, barred body 51 is integrally formed with collar nut 52, and as shown in Figure 6 and Figure 7, barred body 51 and collar nut
52 are engaged by clamping, and specifically, the end of barred body 51 is expanded in bulb 56, and the bulb 56 can realize card with collar nut 52
Cooperation is connect, so as to realize that the on-fixed between collar nut 52 and barred body 51 connects, barred body 51 can be with the affixed joint in one end
Nut 52, one collar nut 52 of other end clamping, or, the both ends of barred body 51 can one collar nut 52 of clamping.
Connecting bolt 4 is opposite with the hand of spiral for two ends that attaching nut 2 and collar nut 52 are spirally connected respectively.It is preferred that
Ground, has the fastener 41 in polygon on connecting bolt 4, and positioned at the both sides of fastener 41 hand of spiral on the contrary, spanner etc.
Instrument can be coordinated with fastener 41 for the bolt 4 that is rotatably connected.
The present invention operation principle be:Bar component 5 is embedded to two opposite prefabricated structures for needing to connect in advance respectively
In part 100, prefabricated components 100 can be wall, cement block, pipeline, pile tube etc., the connection end 11 of connection-peg 1 with wherein
One collar nut 52 is spirally connected fixation, and connecting bolt 4 and another collar nut 52 are spirally connected fixation, and attaching nut 2 is with being connected spiral shell
Bolt 4 is spirally connected fixation, successively in attaching nut 2 be put into elastic component 21, packing ring 22, snap ring assemblies 23 after use the spiral shell of intermediate nut 3
Enter into attaching nut 2, intermediate nut 3 pushes down the one side of snap ring assemblies 23, and packing ring 22 pushes up under the elastic force effect of elastic component 21
The firmly another side of snap ring assemblies 23, the inserted terminal 12 of connection-peg 1 is inserted into intermediate nut 3, when annular slot 13 and snap ring group
After part 23 is engaged by clamping, inserted terminal 12 is realized to be engaged by clamping with attaching nut 2 and fixed.
With reference to shown in Fig. 2 and Fig. 3, now, nut 2 or connecting bolt 4 are rotatablely connected, connecting bolt 4 can be adjusted and entered
To the length in attaching nut 2, so as to adjust the length of whole connector, also with regard to two prefabricated components for needing to connect can be adjusted
Length between 100, because elastic component 21 has compressibility, therefore be in course of adjustment connection-peg 1 all the time with attaching nut 2
It is engaged by clamping.Or rotation connection bolt 4 adjusts the length that connecting bolt 4 is entered in collar nut 52, equally can also adjust
The length of whole connector, but the distance of this adjustment is influenceed by collar nut 52 and the fitness of connecting bolt 4, regulation
Distance it is limited.
, can such as the ot-yet-hardened of prefabricated components 100 when in the prefabricated components 100 that bar component 5 is embedded to cement mortar
To be passed through air to air flow channel 53 from collar nut 52, and blown out from solarization air cap 54, not solidified prefabricated components 100 are added
Speed hardening.The grout hole 55 being communicated with the outer wall of collar nut 52 inside collar nut 52, cement mortar can be from grout holes 55
Enter inside collar nut 52, when cement slurry sets, dock the connection-peg 1 inside head nut 52 and/or connecting bolt 4 rises
To fixation, so as to improve the structural strength of whole connector.
