Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Figure 1, a kind of unitary nut connector, comprise a connection-peg 1 and an attaching nut 2, there is in described attaching nut 2 chuck 3 outstanding to direction of axis line, be bolted with connecting bolt 4 in attaching nut 2, be plugged with connection-peg 1 in described attaching nut 2 and connection-peg 1 and chuck 3 connect and fix.The length of attaching nut 2 is entered into, i.e. the length of the whole connector of adjustable by adjustment connecting bolt 4.Described attaching nut 2 has one in polygonal positioning step 25 away from one end of connecting bolt 4, and the fastened tools such as convenience spanner are fixed on the positioning, thus are convenient to be fixedly connected with nut 2.Attaching nut 2 of the present invention is integral type structure, easy to connect, improves connection speed and structural strength.
Elastic component 21 is provided with successively in attaching nut 2 from connecting bolt 4 toward the direction of connection-peg 1, packing ring 22 and snap ring assemblies 23, elastic component 21 can be spring or cylindrical spring, described snap ring assemblies 23 matches with the end of chuck 3 and is pushed into by elastic component 21 in the end of chuck 3, when connection-peg 1 is inserted in chuck 3, snap ring assemblies 23 can block connection-peg 1 thus connection-peg 1 and chuck 3 are connected and fixed, shown in composition graphs 4, described snap ring assemblies 23 comprises several annularly circumferential cards 24 distributed of draw-in groove 13, card 24 is that quantity is more than 2, be preferably 4, the structure of composition annular.
Connection-peg 1 comprises link 11 and inserted terminal 12, and described inserted terminal 12 has the annular slot 13 matched with snap ring assemblies 23, and when snap ring assemblies 23 snaps onto after in annular slot 13, namely inserted terminal 12 is stuck fixing, also just realizes clamping with chuck 3.Connection-peg 1 is connected to bar assembly 5 away from one end of attaching nut 2 and connecting bolt 4 away from one end of attaching nut 2.In the present embodiment, link 11 jointing nut 52, connecting bolt 4 also connects a collar nut 52.
As shown in Figure 5, the collar nut 52 that bar assembly 5 comprises barred body 51 and is connected with the end of barred body 51, described collar nut 52 has internal thread, and described collar nut 52 is spirally connected fixing with connecting bolt 4 or connection-peg 1.Barred body 51 inside is provided with the air flow channel 53 being axially arranged with hollow along barred body 51, described barred body 51 outer wall is provided with the solarization air cap 54 be communicated with air flow channel 53, described air flow channel 53 is communicated with collar nut 52, and the sidewall of described collar nut 52 is provided with at least one grout hole 55.
As shown in Figure 5, barred body 51 is one-body molded with collar nut 52, as shown in Figure 6 and Figure 7, and barred body 51 and collar nut 52 snap-fit engagement, specifically, the end of barred body 51 to expand in the portion of expanding 56, and this expands portion 56 and can realize snap-fit engagement with collar nut 52, thus the on-fixed realized between collar nut 52 with barred body 51 is connected, barred body 51 can the affixed collar nut 52 in one end, other end clamping collar nut 52, or barred body 51 two ends can clamping collar nut 52.
Connecting bolt 4 is contrary with the hand of spiral of two ends that attaching nut 2 and collar nut 52 are spirally connected respectively.Preferably, connecting bolt 4 has in polygonal fastener 41, and the hand of spiral being positioned at fastener 41 both sides is contrary, the instruments such as spanner fastener 41 cooperation can be used for the bolt 4 that is rotatably connected.
Operating principle of the present invention is: bar assembly 5 is embedded in the prefabricated units 100 of two opposite needs connections respectively in advance, prefabricated units 100 can be bodies of wall, cement block, pipeline, pile tube etc., link 11 and one of them collar nut 52 of connection-peg 1 are spirally connected fixing, connecting bolt 4 and another collar nut 52 are spirally connected fixing, attaching nut 2 and connecting bolt 4 are spirally connected fixing, elastic component 21 is put into successively in attaching nut 2, packing ring 22, be threaded in attaching nut 2 by chuck 3 after snap ring assemblies 23, chuck 3 pushes down the one side of snap ring assemblies 23, packing ring 22 withstands the another side of snap ring assemblies 23 under the elastic force effect of elastic component 21, the inserted terminal 12 of connection-peg 1 is inserted in chuck 3, when after annular slot 13 with snap ring assemblies 23 snap-fit engagement, inserted terminal 12 and attaching nut 2 realize snap-fit engagement and are fixed.
Shown in composition graphs 2 and Fig. 3, now, be rotationally connected nut 2 or connecting bolt 4, connecting bolt 4 can be adjusted and enter into length in attaching nut 2, thus adjust the length of whole connector, also just can adjust two need connect prefabricated units 100 between length, because elastic component 21 has compressibility, be therefore in course of adjustment connection-peg 1 all the time with attaching nut 2 snap-fit engagement.Or be rotationally connected bolt 4 and adjust the length that connecting bolt 4 enters into collar nut 52, equally also can adjust the length of whole connector, but the distance of this adjustment is subject to the impact of collar nut 52 and connecting bolt 4 fitness, the distance of adjustment is limited.
When in the prefabricated units 100 that bar assembly 5 is embedded to cement paste, as prefabricated units 100 ot-yet-hardened, from collar nut 52, air can be passed into air flow channel 53, and blow out from solarization air cap 54, sclerosis is accelerated to not solidified prefabricated units 100.Collar nut 52 outer wall is provided with the grout hole 55 being communicated with collar nut 52 inside, it is inner that cement paste can enter into collar nut 52 from grout hole 55, when cement slurry sets, connection-peg 1 and/or the connecting bolt 4 of butt joint nut 52 inside play fixation, thus improve the structural strength of whole connector.
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.
Although more employ connection-peg 1, link 11, inserted terminal 12, annular slot 13, attaching nut 2, elastic component 21, packing ring 22, snap ring assemblies 23, card 24, positioning step 25, chuck 3, connecting bolt 4, fastener 41, bar assembly 5, barred body 51, collar nut 52, air flow channel 53, solarization air cap 54, grout hole 55, the terms such as portion 56 that expand herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
