Description

A kind of dismountable upset bolt of screw rod
Technical field
Fastener is the utility model is related to, refers in particular to a kind of dismountable upset bolt of screw rod.
Background technology
Expansion bolt is widely used in building trade, particularly requires fixed occasion at some, as pendent lamp, air-conditioning, Installation of water heater etc.;Although the fixed object of expansion bolt is firm, installation is simple, and not easy to remove after installation, tolling breakdown to destroy Wall, therefore expansion bolt can only be stayed in wall, cause expansion bolt to carry out secondary use, in addition, some expand The bolt head of bolt is often convex on wall or ground, not only influences attractive in appearance, and causes potential safety hazard.
Utility model content
The purpose of the utility model is to provide a kind of screw rod dismountable expansible for overcome the deficiencies in the prior art Bolt, can not only as common expansion bolt convenient use, and detachably, recovery, it is also reusable, so as to save into Originally, ensure that metope is attractive in appearance.
To reach above-mentioned purpose, the technical solution adopted in the utility model is:A kind of dismountable expansible spiral shell of screw rod Bolt, include screw rod, nut, expansion sleeve;The expansion sleeve is set on screw rod;The screw rod includes optical axis and thread spindle; The outer end of the optical axis is conical head, and the inner is provided with coaxial screwed hole;The big end external diameter of the conical head is more than expansion sleeve The internal diameter of pipe;The inner of the thread spindle is provided with the stud being threadedly coupled with screwed hole, and expansion sleeve and and spiral shell are stretched out in outer end Box thread connects;Pad is additionally provided with the thread spindle between expansion sleeve and nut;The thread rotary orientation of the screwed hole It is opposite with the thread rotary orientation of nut.
Preferably, the outer end of the thread spindle is additionally provided with the countersunk head groove for connecting interior spanner.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art:
The dismountable upset bolt of screw rod described in the utility model can not only facilitate as common expansion bolt Use, and detachably, recovery, it is also reusable, so as to save cost, ensure that metope is attractive in appearance.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings:
Accompanying drawing 1 is the structural representation of the dismountable upset bolt of screw rod described in the utility model.
Wherein:1st, optical axis;11st, conical head;2nd, expansion sleeve;3rd, thread spindle;31st, stud;32nd, countersunk head groove;4th, pad;5、 Nut.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Accompanying drawing 1 is the dismountable upset bolt of screw rod described in the utility model, includes screw rod, nut 5, expansion sleeve Pipe 2;The expansion sleeve 2 is set on screw rod;The screw rod includes optical axis 1 and thread spindle 3;The outer end of the optical axis 1 is cone Forming head 11, the inner are provided with the screwed hole coaxial with optical axis 1;The big end external diameter of the conical head 11 is more than the interior of expansion sleeve 2 Footpath;The inner of the thread spindle 3 is provided with the stud 31 being threadedly coupled with screwed hole, outer end stretch out expansion sleeve 2 and with nut 5 Threaded connection;Pad 4 is additionally provided with the thread spindle 3 between expansion sleeve 2 and nut 5;When expansion bolt is installed, first Expansion bolt is inserted in mounting hole, now using two spanners, one is used for stationary threaded shaft 3, prevents thread spindle 3 from rotating, Another is used for rotating nut 5, and because expansion sleeve 2 is motionless, nut 5 drives thread spindle 3 to move axially, will using conical head 11 The spreading of expansion sleeve 2, and twist must be tighter, increase bigger, now, expansion bolt just can pull out Chu Lai, is fixed in wall; When need remove expansion bolt when, thread spindle 3 is pulled by spanner, just thread spindle 3 can be made to be separated with optical axis 1, by thread spindle 3 from Taken out in expansion sleeve 2;The thread rotary orientation of the screwed hole is with the thread rotary orientation of nut 5 on the contrary, avoiding simply having a wrench During rotating nut 5, screwed hole is tightened with stud 31, is unfavorable for thread spindle 3 and is separated with optical axis 1;The outer end of the thread spindle 3 is also set The countersunk head groove 32 for connecting interior spanner is equipped with, is easy to drive the rotation of thread spindle 3 to separate with optical axis 1 by countersunk head groove 32.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art:
The dismountable upset bolt of screw rod described in the utility model can not only facilitate as common expansion bolt Use, and detachably, recovery, it is also reusable, so as to save cost, ensure that metope is attractive in appearance.
It the above is only concrete application example of the present utility model, do not form any limit to the scope of protection of the utility model System.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it It is interior.
