Abstract
The utility model discloses a kind of swell fixture, for solving the problems, such as that the tension pull out force of existing swell fixture and steadiness are poor.Including screw rod, nut, the expansion sleeve being set on the screw rod, described screw rod one end is connected by screw thread with nut, the other end is tapered, direction offers first through hole for irrigating binding agent to the screw rod axially along, and the distending position of the expansion sleeve, which offers, can outwards strut the barb structure to form hangnail.Barb structure of the present utility model outwards struts in the presence of the tapering point of screw rod, its spine position inserting hole hole wall, improves its anti-pulling ability, avoids screw from being released from hole；After screw rod struts expansion sleeve, binding agent is irrigated out of first through hole so that screw rod and expansion sleeve are adhere strongly in hole, further avoid it from releasing, and improve its firm power.
Description
Technical field
A kind of screw is the utility model is related to, is a kind of swell fixture that can be taken root on the wall specifically.
Background technology
Setscrew generally be metallic expansive screw, the fixation of setscrew is to promote to expand using wedge-shaped gradient
Friction bond stress is produced, reaches fixed effect.Screw rod one is screw thread, and one tapered.The outer iron sheet of bread one (has plenty of steel
Pipe), iron sheet cylinder (steel pipe) half has some otch, they is filled in together in the hole accomplished fluently on wall, then split nut, nut
Screw rod is pulled outward, taper is pulled in into iron sheet cylinder, iron sheet cylinder is then tightly secured on wall, is generally used for preventing by spreading
The fastening on the materials such as cement, brick such as guardrail, canopy, air-conditioning.But its fixation is not very reliable, if load have it is larger
Vibrations, it may occur however that release.
Utility model content
The utility model purpose is intended to provide a kind of swell fixture, can be securely seated between screw rod and expansion sleeve
In hole, it is avoided to release.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of swell fixture, including screw rod, nut, the expansion sleeve being set on the screw rod, described screw rod one end lead to
Screw thread is crossed to be connected with nut, the other end is tapered, the screw rod axially along direction offer for irrigate binding agent
One through hole, the distending position of the expansion sleeve, which offers, can outwards strut the barb structure to form hangnail.
Using the utility model of above-mentioned technical proposal, barb structure outwards struts in the presence of the tapering point of screw rod, its
Spine position inserting hole hole wall, improves its anti-pulling ability, avoids screw from being released from hole；Expansion sleeve is strutted in screw rod
After, binding agent is irrigated out of first through hole so that screw rod and expansion sleeve are adhere strongly in hole, are further avoided
It is released, and improves its firm power.
Further limit, that tapered one end of the screw rod offers the second through hole along its radial direction.
Further limit, that less one end of the tapering point size for being located proximate to screw rod of second through hole.
Close to that smaller one end of tapering point size the second through hole so that binding agent can be flowed to from the second through hole screw rod and
Between expansion sleeve, expansion sleeve and screw rod are securely bonded to together, further improve its firm power.
Further limit, the barb structure is triangular in shape.
The barb structure of triangle carries spine position, when screw rod struts the distending position of expansion sleeve, its spine
Position is inserted directly into hole portion.
The utility model has more preferable tension pull out force, fastness, can avoid screw from the hole on wall than prior art
Released in hole.
Brief description of the drawings
The utility model can be further illustrated by the nonlimiting examples that accompanying drawing provides；
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of expansion sleeve；
Structural representation when Fig. 3 is softened for barb structure；
Main element symbol description is as follows：
Screw rod 1, first through hole 11, nut 2, expansion sleeve 3, barb structure 31.
Embodiment
In order that the utility model may be better understood in those skilled in the art, it is right with reference to the accompanying drawings and examples
Technical solutions of the utility model further illustrate.
As shown in Figure 1, 2, 3, a kind of swell fixture, including screw rod 1, nut 2, the expansion sleeve being set on the screw rod 1
Pipe 3, described screw rod one end are connected by screw thread with nut 2, and the other end is tapered, and the screw rod 1 opens up in direction axially along
There is the first through hole 11 for irrigating binding agent, the distending position of the expansion sleeve 3 offers and outwards can strut to form hangnail
Barb structure 31.
That tapered one end of the screw rod 1 offers the second through hole 12 along its radial direction.
That less one end of the tapering point size for being located proximate to screw rod 1 of second through hole 12.
The barb structure 31 is triangular in shape.
Barb structure 31 and expansion sleeve 3 are integral, the consistency of thickness of its thickness and the tube wall of expansion sleeve 3, Bu Huiying
Ring screw to enter in the hole of wall, when the tapering point of screw rod 1 is strutted, can just form hangnail and be directly inserted into hole
In wall, its tension pull out force is improved.
By checking, the binding agent poured into from first through hole 11 can be that AB glue water, 502 glue and marble are special
Cloud stone glue etc..In slightly bigger swell fixture, cement mortar can also be directly poured into, is more nearly the composition of wall, is increased
Add steadiness and adhesive force.
A kind of swell fixture provided by the utility model is described in detail above.The explanation of specific embodiment is
It is used to help understand method and its core concept of the present utility model.It should be pointed out that the ordinary skill people for the art
For member, on the premise of the utility model principle is not departed from, some improvement and modification can also be carried out to the utility model, this
A little improvement and modification are also fallen into the protection domain of the utility model claims.
