Description
Technical field
This utility model relates to hardware products technical field, particularly to a kind of easily detachable setscrew.
Background technology
Setscrew is to be fixed on installed parts such as support, suspension bracket or brackets on the body of wall such as wall, floor to be used
A kind of special thread connector.Setscrew of the prior art all has an expansion tube, by making expansion
Pipe produces dilatancy, and diameter becomes big, realizes and being fastenedly connected of body of wall.But, after dilatancy
Expansion tube cannot recover voluntarily, thus be difficult to pull out and install the setscrew into body of wall, and setscrew can only one
Secondary property uses.When the position in hole of misplaying on body of wall or when needing the position changing hole, due to former use
The most quick detachable taking-up of setscrew, not only increases installation cost, also affects the attractive in appearance of body of wall.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of cost relatively low and can be repeatedly
The easily detachable setscrew used.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is by the following technical programs
Realize: a kind of easily detachable setscrew, including screw rod and sleeve pipe, described screw rod has thread segment and taper
Section, described screw flight section is set with nut and pad, the diameter of the conical section of described screw rod from rear to
Before be gradually increased, described casing pipe sleeve is loaded on the conical section of described screw rod, and described sleeve pipe is provided with fluting, institute
Being provided with swollen post in stating fluting, the medial wall of described sleeve pipe is respectively equipped with one at two ends being positioned at before and after fluting
Recess, is respectively arranged at two ends with a stop tab matched with described recess, described screw rod before and after described swollen post
Thread segment outer end on be arranged with a protective jacket.
Further, the sidewall of described nut is provided with screwed hole, is installed by screw thread in the screwed hole of nut
One is had to hold out against screw.
Further, described sleeve pipe is provided with multiple fluting, is separately installed with a swollen post in each fluting.
The beneficial effects of the utility model are: be set with sleeve pipe on the screw rod in this utility model, sleeve pipe leaves
Being provided with fluting, fluting is built with swollen post, and screw rod has the conical section that diameter is gradually increased, by turning spiral shell
Bar, then under the effect of the tapering of the conical section of screw rod so that a part for swollen post is extruded opening of screw rod
Groove, thus under the effect of the swollen post being extruded so that screw rod is fastened onto on body of wall, is installed to by installed part
On screw rod, and fastening nut, it is achieved installed part and the installation of body of wall.When this setscrew dismantled by needs,
Turning screw rod so that screw rod rollback, swollen post is return, thus just can screw rod and sleeve pipe be taken out the most easily,
Can also be used for use next time, thus reach this utility model utilization quick detachable, repeatable and reduce the mesh of cost
's.It addition, be provided with protective jacket on the outer end of screw rod, it is possible to prevent screw thread to leak outside, both protects screw thread,
Reach again effect attractive in appearance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this utility model
Advantage and feature can be easier to be readily appreciated by one skilled in the art, thus to protection domain of the present utility model
Make apparent clear and definite defining.
As it is shown in figure 1, a kind of easily detachable setscrew, including screw rod 1 and sleeve pipe 2, described screw rod 1 has
There are thread segment 11 and conical section 12, the thread segment 11 of described screw rod 1 be set with nut 5 and pad 6,
The diameter of the conical section 12 of described screw rod 1 is gradually increased from rear to front, and described sleeve pipe 2 is set in described screw rod
On the conical section 12 of 1, described sleeve pipe 2 is provided with fluting, is provided with swollen post 3, described set in described fluting
The medial wall of pipe 2 is respectively equipped with a recess 21, before and after described swollen post 3 being positioned at before and after fluting at two ends
It is respectively arranged at two ends with a stop tab 31 matched with described recess 21, the thread segment 11 of described screw rod 1
A protective jacket 4 it is set with on outer end.
Furtherly, the sidewall of described nut 5 is provided with screwed hole 51, passes through in the screwed hole 51 of nut 5
Screw thread is provided with one and holds out against screw 7.
Furtherly, described sleeve pipe 2 is provided with multiple fluting, is separately installed with a swollen post 3 in each fluting.
During use, this setscrew is inserted the hole held successfully on body of wall, by turning nut 5 so that screw rod 1
Rotate and move to wall direction, under the effect of the tapering of the conical section 12 at screw rod 1 rear portion, sleeve pipe 2
The swollen post 3 installed in fluting protrudes from the fluting of sleeve pipe 2, thus under the effect that compresses of swollen post 3, screw rod 1
It is fastened on body of wall with sleeve pipe 2.After a part for swollen post 3 is extruded, two ends before and after swollen post 3
Stop tab 31 be resisted against on the recess 21 on the medial wall of sleeve pipe 2, such that it is able to prevent swollen post 3 complete
Abjection sleeve pipe 2.When this setscrew dismantled by needs, turn screw rod 1 so that screw rod 1 rollback, swollen post 3
Return, thus just screw rod 1 and sleeve pipe 2 can be taken out the most easily it can also be used to next time uses, thus reach
Utilization quick detachable to this utility model, repeatable and the purpose of reduction cost.After screw rod 1 is anchored on body of wall,
Installed part is installed on the thread segment 11 of screw rod 1, fastening nut so that installed part is fixedly installed in body of wall
On.The sidewall of nut 5 is screwed on and holds out against screw 7, thus under the effect that holds out against holding out against screw 7 can in case
Only nut 5 loosens.In this utility model, the outer end of screw rod 1 is provided with protective jacket 4, is possible to prevent
Screw thread leaks outside, and has both protected screw thread, has reached again effect attractive in appearance.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion, or directly
Connect or be indirectly used in other relevant technical fields, be the most in like manner included in patent protection model of the present utility model
In enclosing.
