In, until magazine be close to it is fixed outside groove.
As an improvement, the screw can be Philip's head screw or a word screw, after magazine is anchored on groove by the screw
It must not exceed internal thread C depth with the expansion bolt internal thread C reaches being engaged.
As an improvement, expansion bolt, before hole is knocked in, tapered cup nut at least two encloses tooth line and is screwed onto on dormant bolt.
The beneficial effects of the present invention are：
Switch after a long time in use, it is necessary to when changing magazine without chiseling wall take out by magazine ageing of plastics
The magazine of defect inner ear, it is not necessary to bury new magazine again.The present invention uses a kind of expansion bolt of special construction, in expansion bolt
Itself it is upper inner hexagonal hole and internal thread are set, expansion bolt is fixed on wall by inner hexagon spanner, and pass through spiral shell
Nail through magazine and coordinates the internal thread in dormant bolt that magazine is anchored on outside groove, solve magazine hold-doun nut defect without
The problem of panel-switch is fixedly mounted in method.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of expansion bolt；
Fig. 2 is the sectional view of expansion bolt；
Fig. 3 is the sectional view of dormant bolt；
Fig. 4 is the structural representation of tapered cup nut；
Fig. 5 is the method schematic diagram of magazine installation.
Embodiment
Technical solution of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings, to be further understood that
The purpose of the present invention, scheme and effect, but it is not intended as the limitation of scope of the appended claims of the present invention.
As shown in Fig. 1 to Fig. 4, expansion bolt includes dormant bolt 1, tube expansion 3, tapered cup nut 4 and plain washer 2, countersunk head spiral shell
The head center position of bolt 1 is provided with inner hexagonal hole 101, and screw portion is provided with external screw thread 103, and the inside of dormant bolt 1 is additionally provided with
Internal thread C102；The outer surface of tapered cup nut 4 is provided with inclined plane 401 and the face of cylinder 402, and the internal diameter of tapered cup nut 4 is provided with internal thread
Z403。
In view of bolt strength and easy for installation, the maximum gauge of inner hexagonal hole 101 is no more than the head diameter of dormant bolt 1
2/3rds, the depth of inner hexagonal hole 101 is no more than 2/3rds of the head depth of dormant bolt 1；Internal thread C102 hole
Footpath is no more than 2/3rds of the screw diameter of dormant bolt 1, and internal thread C102 and inner hexagonal hole 101 penetrate and internal thread C102
Depth is no more than the length of the screw rod of dormant bolt 1.
In order that tube expansion 3 is more prone to strut and ensures that tube expansion 3 can be rigidly secured in porthole after strutting completely,
The optimal size of angle between the center line of inclined plane 401 and tapered cup nut 4 is 30 ° to 40 °, and the outer surface on the face of cylinder 402 is
Non slip surface with irregular lines, ensure that dormant bolt 1, tapered cup nut 4 can be smoothly toward groove port during rotation
Direction movement can also cause tapered cup nut 4 not follow dormant bolt to rotate and rotate.
From Fig. 5 magazine installation method schematic diagram, cone of the diameter than expansion bolt is drilled with the groove of wall 7
The hole 701 that big 1~2 millimeter of the external diameter of shape nut 4, drill 701 depth be more than the screw rod of dormant bolt 1 length；Expansion bolt
To ensure expansion bolt when hole 701 are knocked in completely into hole 701, basis for estimation be until plain washer 2 be close to it is recessed
Groove bottom, the inner hexagonal hole 101 in expansion bolt then is rotated using inner hexagon spanner, dormant bolt 1 is rotated and by outer
Screw thread between screw thread 103 and the internal thread Z403 of tapered cup nut 4, which engages, moves tapered cup nut 4 toward groove direction, in movement
During, the inclined plane 401 of tapered cup nut 4 struts tube expansion 3, and subsequent expansion bolt, which is fixed, to be completed.
Screw 5 is then passed through to the centre bore of magazine 6, is tightened against screw 5 by the internal thread C102 of expansion bolt swollen
In swollen bolt, until magazine is close to fixed outside groove, screw 5 can be Philip's head screw or a word screw, in order to ensure
Magazine 6 can be anchored on outside groove, and magazine is anchored on the screw thread that it is engaged with expansion bolt internal thread C102 after groove by screw 5
Length must not exceed internal thread C102 depth, in order to prevent expansion bolt tapered cup nut when hole 701 are knocked in from coming off, because
Before hole 701 is knocked in, tapered cup nut 4 at least two encloses tooth line and is screwed onto on dormant bolt 1 this expansion bolt.
In summary, because the expansion bolt and magazine installation method of the present invention are provided using a kind of special construction
Expansion bolt, expansion bolt itself on inner hexagonal hole and internal thread are set, expansion bolt is fixed by inner hexagon spanner
Through magazine and coordinate internal thread that magazine is anchored on outside groove on wall, and by screw, solve magazine and fix spiral shell
The problem of panel-switch can not be fixedly mounted in cap defect.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Know those skilled in the art when can be made according to the present invention it is various it is corresponding change and deformation, but these corresponding change and become
Shape should all belong within the protection domain of appended claims of the invention.
