Description
Technical field
The utility model is related to a kind of expansion bolt, more particularly to a kind of anti-rotational expansion bolt, is used in quick
Installing engineering field.
Background technology
At present, existing expansion bolt occur in use, often prefabricated hole inner arm diameter it is excessive more than swollen
The situation of pipe external diameter, and the tube expansion of expansion bolt and prefabricated hole inner arm be without big frictional connection, nothing again between tube expansion and bolt
Mutually card connection, therefore cause expansion bolt to be rotated with spanner in fastener cycle and rotated, it is impossible to nut is screwed into, makes expanding screw
Bolt cannot expand, and the unstable problem of indivedual expansion bolts occur, both lose time, and expansion bolt is not reached due effect again
Really.
Utility model content
The utility model purpose is to provide a kind of anti-rotational expansion bolt, and the expansion bolt is effectively prevented in wall
Generation is skidded and rotates and cause to release, while effectively prevention tube expansion is rotated in fastener cycle with spanner and screw rod was being fastened
Rotated with spanner in journey, effectively raise installation rate.
Technical solution
A kind of anti-rotational expansion bolt, including tube expansion and tapered fastening screw, are provided with anti-rotation rib, on tube expansion on tube expansion
Rectangular channel is provided with, a groove is provided with set rectangular channel.The utility model set on tapered fastening screw head with it is swollen
The interior swollen rib that tube seat coordinates, the upper and lower side wall of tapered fastening screw head be provided with rectangular channel coordinate in swollen rib, in rectangular channel
A groove is provided with, also has fastening surplus afterwards in place to prevent expansion bolt.
Compared with prior art, the utility model has the advantages that：The utility model simple structure, manufacturing cost
It is low, using convenient.The utility model is provided with rib in tube expansion and tapered fastening screw head, effectively prevent existing expansion bolt
Installed in existing composite light brick wall and easily occur to skid to rotate and cause to release the generation of this phenomenon, while also effective
Prevent tube expansion to be rotated with spanner in fastener cycle to be rotated with spanner in fastener cycle with screw rod, effective raising installs fast
Degree, it is ensured that installation quality.
The utility model this product is cheap, it is easy to assembly to dismount, and is widely used in mining engineering, machinery and other works
Journey vehicular field, can also be used in condition more rugged environment, especially be used in Fast Installation engineering field.This practicality is new
Type strengthens the stability of expansion bolt using Fa Zhang mechanisms are coordinated, and not only protects the safety of personnel, moreover it is possible to effective protection equipment
Safety, at the same the expansion bolt also provide it is bigger bear power, so as to improve the security of various equipment requiring installations, improve
The security of operation, maintenance under the conditions of at the scene, and then for enterprise realizes cost efficiency.Installed in every equipment
0 ﹒ of shortening time 5 hours or so, improves operating efficiency.
It is cost-effective such as that operating efficiency is improved daily：
During 300 yuan/people × 2 people × 0 ﹒ 5=300 yuan/when;
It is 109500 yuan that the expansion bolt as obtained by calculating above is can be saved every year.
The utility model Lay Importance on Practical, principle is succinctly understandable, easy to operate.Especially have aobvious in terms of enterprise's cost efficiency
Write effect.So there is very strong practicality.
The utility model its advantage：First, applicability is extensive.2nd, construction method simply, is easily selected.3rd, installation into
Power is high.4th, bearing capacity is big, tension effect is good.5th, self-locking property is good.6th, simple structure, cost is cheap.7th, it is not required to
Professional construction technique.8th, throw aside without puzzlement.9th, it is time saving, laborsaving, save people, be easy to do mechanization operation.
Brief description of the drawings：Fig. 1 is anti-rotational expansion bolt structural representation of the present utility model；
Fig. 2 is anti-rotational expansion bolt structural representation of the present utility model.
Diagram：1. tube expansion, 2. tapered fastening screw, 3. anti-rotation rib, 4. rectangular channel, 5. in swollen rib.
Specific embodiment
Embodiment 1
The utility model includes tube expansion 1 and tapered fastening screw 2, and tube expansion 1 is provided with rectangular channel 4, in set rectangular channel 4
A groove is provided with, two anti-rotation ribs 3 are symmetrical arranged on tube expansion 1, or in the uniform anti-rotation rib 3 of tube expansion.
When using：Only need to the expansion bolt clamp nut of anti-rotation it is slight tighten after, with tap instrument the swollen of anti-rotation
The swollen bolt that strikes is knocked in the slightly bigger hole being drilled, after nut and pad are backed out, the tapered fastening spiral shell of anti-turning expanding bolt
Bar is installing pad and clamp nut through fixed article hole is needed.Distending tube expansion is i.e. by being fastened with spanner
Can.
Embodiment 2
Including tube expansion 1 and tapered fastening screw 2, tube expansion 1 is provided with rectangular channel 3, and one is provided with set rectangular channel 3
Groove, is provided with anti-rotation rib 4 on tube expansion 1, is set on the head of tapered fastening screw 2 and swollen rib 5, tapered fastening in expanded tube hole groove cooperation
The upper and lower side wall of the head of screw rod 2 be provided with rectangular channel 3 coordinate in swollen rib 5, a groove is provided with rectangular channel 3, to prevent
Expansion bolt also has fastening surplus afterwards in place.Can also play solid to needing using two anti-rotation ribs are symmetrical arranged on tube expansion simultaneously
Earnest product.
