Description
Technical field
The utility model is related to a kind of devices of expansion bolt, more particularly to a kind of anti-turning expanding bolt device.
Background technology
In recent years, China's standard component industry, construction industry, installation industry are quickly grown.The quickening adjustment of National Industrial structure, city
The accelerated development in town, the growth requirement of each related industry and infrastructure construction demand, the development for above-mentioned industry provide
Wide market.
And during the use of expansion bolt, often limited by expansion bolt merging matrix, if matrix strength is inadequate,
It is easy loosely to fall off, so as to cause expansion bolt, synchronous turn easily occurs with tube expansion for the screw rod of expansion bolt during tightening
It is dynamic.
Utility model content
When the purpose of this utility model is for using national standard expansion bolt, expansion bolt during bolt is tightened
The case where screw rod is rotated synchronously with tube expansion, proposes a kind of anti-turning expanding bolt device, to prevent the screw rod of bolt synchronous with tube expansion
Rotation.
To achieve the above object, the utility model provides a kind of anti-turning expanding bolt device, includes with wedge-shaped gradient
Screw rod, nut, washer, tube expansion, the tube expansion are equipped with rubber sleeve, and the rubber sleeve outer surface is equipped with bump structure, described
The inner surface of rubber sleeve is equipped with protruding circular ring, and the end of close nut one end of the tube expansion is equipped with circumferential groove, the circumference
Groove merges with protruding circular ring matching is fixed on the tube expansion end by the rubber sleeve.
Preferably, the other end of the tube expansion is equipped with several notch, and the side of the notch is equipped in circumferencial direction
Embossing.
Based on the above-mentioned technical proposal, the utility model has the advantages that：
The anti-turning expanding bolt device of the utility model is rotated synchronously for screw rod in use with tube expansion
Problem can not only solve the problems, such as to work day and night using the present apparatus, and it is easy to operate, work well, while not by expanding screw
Bolt is placed in the limitation of matrix, can greatly improve working efficiency.
When the utility model is used, during nut is tightened, under the pulling of screw rod, the notch distending of tube expansion,
It is embossed simultaneously, rubber sleeve with the generation friction of matrix hole, achievees the purpose that anti-rotation respectively.The present apparatus can not only solve expanding screw
Bolt the problem of screw rod and tube expansion rotate synchronously in use, and it is easy to operate, it substantially increases expanding screw and tethers
The safety connect has extraordinary practicability, convenient for promoting.
Description of the drawings
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings：
Fig. 1 is anti-turning expanding bolt apparatus structure schematic diagram；
Fig. 2 is rubber sleeve structural schematic diagram；
Fig. 3 is tube expansion structural schematic diagram.
Specific implementation mode
Below by drawings and examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of anti-turning expanding bolt device, and the present apparatus is by screw rod, nut, washer, rubber sleeve, swollen
Five part such as pipe is constituted, and as shown in FIG. 1 to 3, a kind of preferred embodiment of the utility model is shown.Specifically,
The anti-turning expanding bolt device includes screw rod 1, nut 2, washer 3, tube expansion 5 with wedge-shaped gradient, and the tube expansion 5 is equipped with rubber
Gum cover 4,4 outer surface of the rubber sleeve are equipped with bump structure 8, and the inner surface of the rubber sleeve 4 is equipped with protruding circular ring 9, described
The end of close nut one end of tube expansion 5 is equipped with circumferential groove 10, and the circumferential groove 10 merges with the matching of the protruding circular ring 9
The rubber sleeve 4 is fixed on 5 end of the tube expansion.
As shown in Figure 1, the screw rod 1 is with the screw rod of wedge-shaped gradient, national standard product can be used in nut 2, washer 3.Such as
Shown in Fig. 2, the rubber sleeve 4 is by ageing-resistant, wear-resisting, having certain elasticity etc., comprehensive good rubber is made, outside rubber sleeve 4
Surface is designed as the bump structure spread all over 8, and salient point plays the role of increasing friction, and inner surface is designed with the protrusion circle of certain altitude
Ring 9, convenient for being completely embedded with tube expansion 5,4 internal diameter of another rubber sleeve is slightly less than the outer diameter of tube expansion 5.
The tube expansion 5 is the metal sleeve that one end carries several notch 6, and 6 side of notch is in circumferencial direction with embossing 7, pressure
Spend 7 increase rubbing actions；Other end design carries a circumferential groove 10, the circumferential groove 10 and 9 phase of the protruding circular ring
The rubber sleeve 4 is fixed on the tube expansion 5 with merging, convenient for closely being connect with rubber sleeve 4.
The application method of the present apparatus is：
Use preparation：The merging of this anti-turning expanding bolt is accomplished fluently in the matrix of hole, in wall.
Use implementation：The nut for starting to tighten anti-turning expanding bolt with spanner, during tightening, in the pulling of screw rod
Under, the notch distending of tube expansion, while be embossed, rubber sleeve respectively with matrix hole generate friction, achieve the purpose that anti-rotation, until twist
Tightly until the position needed.
The anti-turning expanding bolt device of the utility model is rotated synchronously for screw rod in use with tube expansion
Problem can not only solve the problems, such as to work day and night using the present apparatus, and it is easy to operate, work well, while not by expanding screw
Bolt is placed in the limitation of matrix, can greatly improve working efficiency.
When the utility model is used, during nut is tightened, under the pulling of screw rod, the notch distending of tube expansion,
It is embossed simultaneously, rubber sleeve with the generation friction of matrix hole, achievees the purpose that anti-rotation respectively.The present apparatus can not only solve expanding screw
Bolt the problem of screw rod and tube expansion rotate synchronously in use, and it is easy to operate, it substantially increases expanding screw and tethers
The safety connect has extraordinary practicability, convenient for promoting.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
