Embodiment
Below only with embodiment, the enforcement aspect that the utility model is possible is described, but and be not used to limit the utility model institute for protect category, first give chat bright.
As shown in Figures 1 to 4, the utility model provides a kind of expansion bolt device, and it comprises: tube 2, tapered cup nut 1, screw rod 4.
Wherein, this tube 2 is in tubular, and two ends are the opening be interconnected, and are extended with in the ora terminalis of one end to sidewall the mouth 23 that rises, can spreading by this this tube 2 of mouth 23 that rises, and this mouth 23 that rises to rise mouth for rectangular.
The minimum outer diameter of this tapered cup nut 1 is not more than the internal diameter with the one end of the mouth 23 that rises of this tube 2, at least one place external diameter of the conical section of this tapered cup nut 1 is greater than the internal diameter with the one end of the mouth 23 that rises of this this tube 2, such as this tapered cup nut 1 by outer wall by one end as the other end flaring, make this tapered cup nut 1 can stretch in this tube 2, can the inwall of this tube 2 of spreading by the conical section of this tapered cup nut 1; This tapered cup nut 1 is in hollow, and inwall is provided with screw thread.
This screw rod 4 have can with the first thread section 43 and the second thread section 42 of this tapered cup nut 1 bolt, this the first thread section 43 is arranged on one end of this screw rod 4, one is provided with without thread section 41 between this first thread section 43 and this second thread section 42, this first thread section 43 and the second thread section 42 interval are arranged, and the other end of this screw rod 4 is the drive end 44 that this screw rod of a driving rotates; The length of this second thread section 42 is not less than the length of described tube 2.
Described screw rod 4 penetrates this tube 2 from this first thread section 43, supports to this drive end 44, by this first thread section 43 or this second thread section 42, this screw rod 4 is spirally connected with this tapered cup nut 1.
Preferably, described drive end 4 is the bolt head (as shown in Figure 3) of band plain cushion, applies in big-and-middle-sized expansion bolt device, prevents from destroying attachment face, increases lifting surface area; Or the bolt head of taper (as shown in Figure 4), apply in small-sized expansion bolt device, processing is simple; Or bolt head (as shown in Figure 5) is simply processed, easy to use.
In addition, described drive end 4 is provided with a threaded stem 45 (as shown in Figure 1 and Figure 2) to fix other devices by this threaded stem 45 away from one end of the second thread section 42.
As shown in Figures 1 to 5, described tube 2 is provided with the packing ring 21 be fixedly connected with described tube 2 in the other end, and the external diameter of this packing ring 21 is greater than the simplified external diameter of this tube 2, and this packing ring 21 is supported to this drive end.The problem preventing the drive end 44 brought due to reasons such as pressure, burn into expand with heat and contract with cold from unclamping, when more can prevent from installing, tube 2 too stretches in hole, the problem of the dismounting difficulty caused.And described packing ring 21 periphery is provided with breach 22, preferably, be relatively respectively arranged with a breach 22 in both sides, with this when installing or removing expansion bolt device, snap in this breach 22 by instrument, prevent tube rotational slippage in hole, be convenient to rotary actuation end 44.
When reality uses, in the process of installation, first by described screw rod 4 through the device pre-fixed or directly penetrate in described tube 2, then the first thread section 43 and described tapered cup nut 1 to be spirally connected, to be inserted in the hole of erecting bed afterwards.Then described tapered cup nut 1 rotates to without thread section 41 place by rotary actuation end 44, continuing rotary actuation end 44 again makes tapered cup nut 1 and described second thread section 42 be spirally connected, tapered cup nut 1 will snap in this tube 2, along with the rotation of screw rod 4, external diameter due at least one place conical section of tapered cup nut 1 is greater than the internal diameter of described tube, by the mouth 23 that rises, the sidewall of tube 2 is expanded, make screw rod 4 be fixed on object in hole to reach.
In the process of dismounting, counter-rotating drive end 44, just tapered cup nut 1 can be made to deviate from from the second thread section 42, as for without thread section 41 place, and can prevent tube 22 from spinning by the main breach 22 of tool card, without the need to destroying drive end 44, tapered cup nut 1 can be deviate from from tube 2, now, due to this tapered cup nut 1 at this without thread section 41 place, even if continue to rotate user can feel that this screw rod 4 dallies in tube, this screw rod 4 can be movable in this tube 2, afterwards by the hand toolss such as screwdriver with to prize exposed drive end 44 outside hole or packing ring 21 laterally, can by described tapered cup nut 1, screw rod 4 takes out together with tube 2 from hole, convenient and swift, and do not destroy expansion bolt device.
Preferably, as shown in Figures 3 to 5, because drive end 44 is bolt head, this drive end 44 is driven to rotate by hand toolss such as screwdriver, sleeve, spanners.When as shown in Figure 1 and Figure 2, when having threaded stem 45, the sleeve by spanner or lengthening drives this drive end 44 to rotate.
Preferably, as shown in Figures 1 to 5, the locking process of elastic washer is provided with between described tube 2 and described drive end 44.
Preferably, as shown in Figures 1 to 5, described tapered cup nut 1 is provided with a card bait 11, and the outer wall of this tapered cup nut 1 given prominence to by this card bait 11, and at least one described in rise mouth 23 correspondence arrange and this mouth 23 that rises can be snapped in, with this when mounted, can prevent described tapered cup nut 1 from rotating.Described rise mouth 23 on described tube 2 sidewall in crossing distribution, hexagon distribution, in-line distributes, and this card bait 11 can be one or more, rotates and can snap in this to card bait 11 each during an angle and rise in mouth 23.Preferably, as shown in Figures 1 to 5, described card bait 11 is arranged on the side near described tube 2.Wherein, the cross section of described card bait 11 can be triangular in shape or semicircle.
Preferably, as shown in Figure 1, described tube 2 outer wall is provided with the cunning of putting protruding from this tube 2 outer wall and puts 24 on the downside of the described mouth 23 that rises.This skid-proof point 24 can be circular or square.
In another preferred embodiment of the present utility model, as shown in Figure 6, this mouth 23 that rises is made up of first mouth 231, second mouth 232, the 3rd mouth 233 that rises that rises that rises, preferably, this first rise mouth 231 (but not as limit) triangular in shape, this second rises by mouth 232 in pentagon (but not as limit), the 3rd rises mouth 233 ovalize (but not as limit).This first rise mouth 231, this second mouth 232, the 3rd mouth 233 that rises that rises is communicated with by the gap 234 that rises.
In sum, the design that the utility model is separated by tapered cup nut and screw rod, ensure that when dismantling, by rotary screw, tapered cup nut can be deviate from from tube quickly and easily, be convenient to dismounting, and by the setting without thread section, ensure that tapered cup nut, tube takes out together from hole, can utilizing by secondary, without the need to again punching, ensure that the attractive in appearance of attachment face.And by skid-proof point, card bait, the setting of packing ring breach can prevent tapered cup nut and tube rotational slippage in hole, facilitates installing/dismounting.
