Abstract
The utility model provides an anti-explosion type pull explosion screw, comprising a nut, a screw rod and an explosion sleeve. The nut is arranged on the top of the screw rod. The periphery of the lower part of the screw rod is provided with outside thread. The upper end of the explosion sleeve is a plurality of splinters. The lower part of the inner part of the explosion sleeve is provided with inside thread. The anti-explosion type pull explosion screw can be mounted in a time and labor saving manner, and is small in occupation space.
Description
Technical field
The utility model relates to the hardware products technical field, particularly a kind of anti-quick-fried formula pull explosive screw.
Background technique
The anti-quick-fried formula 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 anti-quick-fried formula 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 anti-quick-fried formula 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 anti-quick-fried formula pull explosive screw that takes up room.
To achieve these goals, the utility model provides following technological scheme:
A kind of anti-quick-fried formula pull explosive screw; It comprises: nut, screw rod and blast cover, 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 upper end of said blast cover is the multi-disc sliver, and the inner bottom of said blast cover is provided with internal thread.
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, also comprise elasticity iron ring and the packing ring that is enclosed within on the said screw rod.
Through implementing above technological scheme, have following technique effect: the anti-quick-fried formula pull explosive screw that the utility model provides is passed material installed and is directly put into the hole, screws screw rod the blast cover is popped, and fixedly material installed is accomplished in disposable operation.Solve anti-quick-fried formula 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, and twists the screw rod derotation can take out at available multiple instrument when not required, and is easy to use.
Description of drawings
The exploded view of the anti-quick-fried formula pull explosive screw that Fig. 1 provides for the utility model embodiment;
The structural representation of the nut that Fig. 2 provides for the utility model embodiment;
The structural representation of the anti-quick-fried formula pull explosive screw that Fig. 3 implements for the utility model to provide.
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 anti-quick-fried formula pull explosive screw; As shown in figures 1 and 3; This anti-quick-fried formula pull explosive screw comprises: nut 110, screw rod 120 and blast cover 140, and said nut 110 is arranged on the top of said screw rod 120, and the periphery of the bottom of said screw rod 120 is provided with outside thread 121; The upper end (towards an end of nut) of said blast cover 140 is a multi-disc sliver 141; This blast cover 140 be the body of hollow, and the bottom of the hollow of this blast cover 140 is provided with internal thread, and this outside thread 121 and said internal thread cooperatively interact the said blast of packing into of said screw rod 120 is overlapped in 140.
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 blast cover 140 easily.
On the basis of the foregoing description, further, the anti-quick-fried formula pull explosive screw of as shown in Figure 1 this also comprises the elasticity iron ring 130 and packing ring 170 that is enclosed within on the said screw rod.
The anti-quick-fried formula pull explosive screw that the foregoing description provides is passed material installed and is directly put into the hole, screws screw rod 120 blast cover 140 is popped, and fixedly material installed is accomplished in disposable operation.Solve former anti-quick-fried formula 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, and twists the screw rod derotation can take out at available multiple instrument when not required, and is easy to use.
More than a kind of anti-quick-fried formula 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.
