Description
Technical field
The invention belongs to metal connecting piece field, be specifically related to a kind of self-lock expansion bolt with self-locking device.
Background technology
Expansion bolt, be pipeline is propped up/hangs/bracket or equipment is fixing on the wall, on floor, a kind of special thread connector used on post.Expansion bolt is made up of dormant bolt, tube expansion, plain washer, spring pad and hex nut.Expansion bolt has a wide range of applications in building and house ornamentation field, but cannot be used for the fixing of architectural surface, and the nut impact that should be protrusion is attractive in appearance, the problem also having weatherability difference for outdoor.
Summary of the invention
The invention aims to provide a kind of easy for installation, both artistic and practical self-lock expansion bolt.
In order to solve above-mentioned technical problem, the technical scheme that the present invention takes is as follows:
A kind of self-lock expansion bolt, it includes that sub-pin, expansion tube and self-locking device, expansion tube one end are provided with block, and the other end is tubulose, is provided with interior six side's screw rods and fixing nut inside expansion tube, and self-locking device is fixed on tubulose one end of expansion tube.
Above-mentioned self-lock expansion bolt, its described son pin is for one end with the bolt of tapered head, and the external diameter of conical head is than the diameter of bolt big 1/3rd.
Above-mentioned self-lock expansion bolt, the funnel shaped that its described block is made up of tapered expansion block.
Above-mentioned self-lock expansion bolt, its described self-locking device includes load disk, can separately sell sheet and position-arresting disk, can separately sell sheet outer shroud and arrange week coil spring, can separately sell sheet and be positioned in the middle of load disk and position-arresting disk, and position-arresting disk is connected with the tubulose end face of expansion tube.
Above-mentioned self-lock expansion bolt, its described self-locking device includes load disk, can separately sell sheet and spring leaf, and spring leaf one end is arranged on can separately sell on sheet, and the other end is fixed on expansion tube inwall.
Above-mentioned self-lock expansion bolt, what it was described can separately sell sheet is made up of pin sheet more than two panels or two panels.
Above-mentioned self-lock expansion bolt, the hole size of its described load disk is more than the conical head external diameter of son pin, and load disc thickness matches with tension pull out force.
Above-mentioned self-lock expansion bolt, its described hole size that can separately sell sheet and son pin equal diameters.
Beneficial effect:
The self-lock expansion bolt that the present invention provides, including sub-pin, expansion tube and self-locking device, expansion tube one end is provided with block, the other end is tubulose, interior six side's screw rods and fixing nut it is provided with inside expansion tube, self-locking device is fixed on tubulose one end of expansion tube, and fixing nut is arranged in expansion tube, by self-locking device fixed expansion bolt.Described self-lock expansion bolt is contrary with the expansion fashion of common expansion bolt, plain bolt is to tighten with nut, screw rod is made to pull out, nut affects attractive in appearance outside, self-lock expansion bolt is screw rod precession, in order to the interior space of self-locking device when not affecting intron pin, and the end face of self-locking device is concordant with fixture, easy to operate and both artistic and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings summary of the invention is made detailed explanation.
nullThe present invention includes sub-pin 1、Expansion tube 8 and self-locking device，Expansion tube 8 one end is provided with block 7，The other end is tubulose，Expansion tube 8 is internal is provided with interior six side's screw rods 6 and fixing nut 5，Self-locking device is fixed on tubulose one end of expansion tube 8，Sub-pin 1 is the one end bolt with tapered head，The external diameter of conical head is than the diameter of bolt big 1/3rd，Expansion tube 8 is from fixing nut less than 5，Prolong pipe range direction and be divided into a few decile，Every part sets an expanding block，All expanding blocks one infundibulate block 7 of composition，Self-locking device includes load disk 2、Can separately sell sheet 3 and position-arresting disk 4，The hole size of load disk 2 is more than the conical head external diameter of sub-pin 1，Load disk 2 thickness matches with tension pull out force，Can separately sell sheet 3 to be made up of three pin sheets，Its hole size is consistent with sub-pin 1 diameter，Outer shroud arranges week coil spring 9，Can separately sell sheet 3 to be positioned in the middle of load disk 2 and position-arresting disk 4，Position-arresting disk 4 is connected with the tubulose end face of expansion tube 8，Prevent from can separately selling sheet 3 slide anteroposterior in expansion tube.
As further improving, described self-locking device includes load disk, can separately sell sheet and spring leaf, the hole size of load disk is more than the conical head external diameter of son pin, load disc thickness matches with tension pull out force, can separately sell sheet to be made up of three pin sheets, its hole size is consistent with son pin diameter, and spring leaf one end is arranged on can separately sell on sheet, the other end is fixed on expansion tube inwall, simultaneously works as condensing together and the effect spacing to pin sheet several separately pin sheets.The conehead plug-in type of group pin, pin sheet outwards separates, and after major part streaks, pin sheet under the action of the spring, lived by inward collapsible by sub-lock.
This self-lock expansion bolt is divided into two parts, a part to be son pin, can be fixed on the inner side of decorative cover, and a part is that the expansion bolt of band self-locking device can be placed on fixture.During use, under the turn of interior six side's screw rods, conehead may be inserted in infundibulate, it is made to extend to surrounding, thus realize the effect making expansion tube expand so that it is being fixed, this expansion fashion is contrary with the expansion fashion of common expansion bolt, plain bolt is to tighten with nut, making screw rod pull out, our expansion fashion is screw rod precession, in order to the interior space of self-locking device when not affecting intron pin.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
