Description
Technical field
The invention belongs to bolt technical field, more particularly to the expansion bolt that a kind of easy taking-up can be reused.
Background technology
At present, the principle of in the market expansion bolt is the Kong Zhonghou that expansion bolt is got on ground or metope, uses spanner
The nut 1c on expansion bolt is tightened, bolt walks toward outside, and the expansion sleeve of outside is motionless, then, the major part under bolt 1
(conical head) makes the whole mounting hole of its overflow just the spreading of expansion sleeve 2, and now, expansion bolt is just fixed, and sees Fig. 1.If
Relatively elaborate when wanting to take out, it is difficult to take out, metope must be destroyed sometimes could be taken out.If it is contemplated that when one kind is not only used
Fixation and it is easy to the expansion bolt for taking out, will be more many than existing this design.
The Chinese patent of Application No. CN201520684502.0 discloses a kind of expansion bolt, including countersunk head screw rod, swollen
Pipe, countersunk head screw rod rear portion is provided with screw thread, some inflation openings is provided with the rear sidewall of tube expansion, and tube expansion front portion is provided with some insertions
Stretched into tube expansion from tube expansion front portion at notch, countersunk head screw rod rear portion；Countersunk head screw rod rear portion is additionally provided with tensioner ring, and tensioner ring is frustum, swollen
The screwed hole through its front/rear end is provided with ring, tensioner ring coordinates with countersunk head screw rod screw thread.Countersunk head screw rod is manipulated to rotate, but due to
The tensioner ring at countersunk head screw rod rear portion rubs with tube expansion side wall, and tensioner ring coordinates with countersunk head screw rod screw thread, and tensioner ring is with respect to countersunk head screw rod
There are axial displacement, i.e. tensioner ring anterior mobile to countersunk head screw rod, tensioner ring rear portion is gradually stretched into tube expansion, by the support of tube expansion rear sidewall
Open, reach the purpose of expansion.The expansion bolt complex structure, and it is inconvenient when taking out, that is, enable and take out, can not circulate
Utilize.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides the expansion bolt that a kind of easy taking-up can be reused, described new
Expansion bolt, not only more consolidates when using, and is also easily all taken out when not using.
Technical scheme is as follows：The expansion bolt that a kind of easy taking-up can be reused, including screw rod 1 and expansion sleeve
Pipe 2, it is characterised in that one end of the screw rod 1 is provided with positive silk tooth 1a, the other end is provided with reverse silk tooth 1b；On the screw rod 1
Expansion sleeve 2 is packaged with, the middle part of expansion sleeve 2 is provided with inflation openings 2a, is formed respectively with and spiral shell on the inwall at the two ends of expansion sleeve 2
The screw thread that the positive silk tooth at the two ends of bar 1, reverse silk tooth match.Expansion sleeve is made up of metal material, can select as needed
The metal of suitable stiffness and elasticity.
Further, one end termination of the screw rod 1 is provided with object fixture 1d.
Further, the object fixture 1d is hook solid or screw shaped.After expansion bolt is installed, object can be hung
On object fixture 1d.
Further, one end termination of the screw rod 1 is provided with nut 1c, and nut 1c is fixed as one with screw rod 1.
Further, the nut 1c is provided with groove 3, the groove 3 and object fixture 1d in the one end away from screw rod 1
Connection.
Further, the expansion sleeve 2 is provided with 3~6 inflation openings, and the length of inflation openings is 3~15cm.
Further, the expansion sleeve 2 is provided with 3~6 inflation openings, and the length of inflation openings is 3~15cm, swollen
Expansion set length of tube and inflation openings length can modify setting according to actual needs.
Further, the screw rod 1 and expansion sleeve 2 are an encapsulated moulding, 2 positive and negative silk tooth and spiral shell on expansion sleeve
Positive and negative silk tooth on bolt is supporting.Expansion sleeve is encapsulated in when on screw rod 1, and the half (section) supporting with screw rod top silk tooth is expanded
Then second half (section) expansion sleeve is enclosed within the bottom of screw rod, the connection of two halves (section) expansion sleeve again on screw rod for casing pipe sleeve
Place is connected using spot welding mode, and inflation openings can be again opened up after expansion sleeve is encapsulated in screw rod, also can first be opened and be expanded
Be encapsulated in expansion sleeve on screw rod again by mouth.
Operation principle of the invention is as follows：The expansion bolt is mainly made up of 2 two parts of screw rod 1 and expansion sleeve,
Wherein the two ends of screw rod 1 make positive silk tooth 1a and reverse silk tooth 1b, nut 1c and object fixture 1d respectively.In expansion sleeve 2
Portion is provided with inflation openings 2a, is made respectively on the inwall at the two ends of expansion sleeve 2 and the two ends of screw rod 1 forward direction silk tooth and reverse silk tooth phase
The screw thread of matching.Can be pressed with several teeth at 2 sets of sides of expansion sleeve, teeth be easy to it is several convex on two surfaces of nut 1c
Contact is played, nut 1c rats are contacted with the teeth at 2 sets of edges of expansion sleeve, and expansion sleeve 2 can be driven to rotate.In processing
During production, expansion sleeve 2 of the inside containing positive and negative silk tooth is once encapsulated on screw rod 1, just constitute the easy taking-up can be again
The multiple expansion bolt for utilizing.
When in use, in the mounting hole first accomplished fluently the insertion of one end of whole expansion bolt in advance, then by up time on screw rod 1
Pin rotates, because screw rod forward direction silk tooth 1a and reverse silk tooth 1b direction of rotation are conversely, expansion sleeve 2 produces axial position to centre
Move, i.e., the top of expansion sleeve 2 and the bottom of expansion sleeve 2 extrude to the center of expansion sleeve 2, the middle part of expansion sleeve 2 is provided with swollen in advance
Distending mouthful 2a, now, inflation openings 2a is squeezed rear distending and outwards expands, and outwards the expansion sleeve 2 of expansion presses to mounting hole
At inwall, increase resistance, so as to allow expansion bolt to be fixed in mounting hole, it is necessary to fixed object, can be fixed by object
Part 1d is fixed.
During taking-up, the nut 1c on screw rod 1 carries out rotate counterclockwise, due to positive silk tooth 1a and reverse silk tooth 1b just phase
Instead, the upper and lower part of expansion sleeve 2 is made to be stretched gradually to both sides, until being fully straightened at inflation openings 2a, expanding screw
Bolt just all can take out from mounting hole.This design not only fixation of the present invention, while also allow for taking out expansion bolt, than
Existing this design is convenient a lot.
Compared with prior art, the invention has the advantages that：The expansion bolt simple structure that the present invention is provided, makes
With convenient, fixation, while also allowing for taking out, and structure will not be damaged, can circulating repetition use.
