Description
Technical field
The utility model relates to the hardware products technical field, particularly a kind of pull explosive screw.
Background technique
The pull explosive screw that existing technology provides, it is made up of the tapered screw rod in lower end, overcoat, nut, and screw rod is through at overcoat and with nut screw rod is fixed then, during use; Bore a hole that matches with overcoat on the wall or on the ground earlier, put into pull explosive screw then, the turn nut; Screw rod is extracted out, because the screw rod lower end is up-small and down-big taper, under the effect of screw rod tapering part; Three slivers in overcoat lower end can pop and press the inner face in hole outward, and pull explosive screw just is fixed on the wall or on the ground, outwards winding nut material installed is loaded onto; Again the nut screw-in is compressed, so just relatively more difficult, time-consuming many when mounted; And after installing, nut and one section very long screw rod are exposed, and take up room, and are prone to scrape that thing is hurted sb.'s feelings and not attractive in appearance.Not difficult again taking-up of time spent.
The model utility content
The utility model provides a kind of and installs time saving and energy saving and the little pull explosive screw that takes up room.
To achieve these goals, the utility model provides following technological scheme:
A kind of pull explosive screw; It comprises: nut, screw rod and expansion sleeve, and said nut is arranged on the top of said screw rod, and the periphery of the bottom of said screw rod is provided with outside thread; The bottom of said expansion sleeve is divided into the multi-disc sliver; Said expansion sleeve top is divided into hollow sleeve, is provided with internal thread in the said hollow sleeve, and the lower end of said expansion sleeve is provided with base.
Preferably, said nut is the nut of regular hexagon, and the center of the top end of said nut is provided with cross recess, and the bottom of said screw rod is divided into taper.
Preferably, the periphery of said base is provided with non-slip groove.
Preferably, also comprise the spring ring and pad money that is enclosed within on the said screw rod.
Through implementing above technological scheme, have following technique effect: the pull explosive screw that the utility model provides is passed material installed and is directly put into the hole, screws screw rod expansion sleeve is popped, and fixedly material installed is accomplished in disposable operation.Solved pull explosive screw and be difficult to a difficult problem that the object that is fixed is installed simultaneously, to install time saving and energy saving.After installing, only expose the outer-hexagonal nut of an arc dome band cross groove, both attractive in appearance, do not hurt sb.'s feelings, scrape thing again.And twist the screw rod derotation can take out in tool when not required.

Embodiment
In order better to understand the technological scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of pull explosive screw; Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, this pull explosive screw comprises: nut 110, screw rod 120 and expansion sleeve 140, and said nut 110 is arranged on the top of said screw rod 120; The periphery of the bottom of said screw rod 120 is provided with outside thread 121; This expansion sleeve 140 is the body of hollow, and the lower end of said expansion sleeve 140 (end of nut dorsad) is multi-disc sliver 141, and the top of said expansion sleeve 140 is divided into hollow sleeve; Said hollow sleeve set inside has internal thread, and the lower end of said expansion sleeve 140 is provided with base 150.This outside thread 121 and said internal thread cooperatively interact said screw rod 120 are packed in the said expansion sleeve 140.Said base 150 is presented the big taper of (direction towards nut is last) little down (direction of nut is down dorsad).
In the above-described embodiments, preferably, as shown in Figure 2; Said nut 110 is the nut of regular hexagon, and the center of the top end of said nut 110 is provided with cross recess 111, and the bottle openers different with convenient, flexible use carry out knob; As shown in Figure 1; The bottom of said screw rod 120 is divided into taper, and the periphery of this taper is provided with above-mentioned outside thread 121, to insert said expansion sleeve 140 easily.
On the basis of the foregoing description, further, as shown in Figure 4, the periphery of said base 150 is provided with non-slip groove 151, to prevent screw rod 120 and expansion sleeve 140 phenomenon of rotating synchronously takes place when installation is screwed.
On the basis of the foregoing description, further, like Fig. 6 and shown in Figure 7, this pull explosive screw also comprises the spring ring 130 and pad money 170 that is enclosed within on the said screw rod.
The pull explosive screw that the foregoing description provides is passed material installed and is directly put into the hole, screws screw rod 120 expansion sleeve 140 is popped, and fixedly material installed is accomplished in disposable operation.Solve former pull explosive screw and be difficult to a difficult problem that the object that is fixed is installed simultaneously.Thereby will the installation time from before shortened to present five minutes in ten minutes, time saving and energy saving, and elegant in appearance.And the outer-hexagonal nut that only exposes an arc dome band cross recess after installing does not affect the appearance and do not take too much spatial position, at fixed object when not required; Only need with the rotation of instrument inhour; Can take out pull explosive screw, avoid the pull explosive screw of existing technology, take out difficult defective when not required at material installed; Can be recycled, save cost.
More than a kind of pull explosive screw that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
