Abstract
The utility model provides a swelling cover which comprises a cover body. The cover body is of a cylindrical cover body or a conical cover body. The cover body comprises elastic claws, claw grooves and a gap groove, wherein the gap groove is arranged in the shaft axis of the cover body, the claw grooves are arranged around the gap groove, and the swelling cover is made of plastics or rubber. The swelling cover is convenient to install, firm, reliable, practical, and impact resistance. The swelling cover is not easy to be pulled out, can not be broken, has good elasticity, has good tension force, has high hardness, and has no rust problem. Thus, sliding of the swelling cover is avoided after the swelling cover is installed, and work efficiency and installment quality are guaranteed. Besides, the swelling cover has strong toughness, is not easy to age even in moist environment, and the overall structure of the swelling cover does not loose. Thus, long-term use of the swelling cover after installation is guaranteed.
Description
Technical field
The utility model relates to a kind of expansion sleeve.
Background technique
In the process of installing and fixing, how to guarantee can not become flexible for a long time after the fixed installation, and under the prerequisite of lower cost, be convenient to install, guarantee work efficiency, be the problem that in installing and fixing the design and production of workpiece, should solve.Adopt stopper to strengthen fixing in the traditional approach, the serviceability that affects fixed effect and stopper but stopper easily skids off is also undesirable.
The model utility content
The purpose of this utility model provides a kind of expansion sleeve solution and how to guarantee can not become flexible for a long time after the fixed installation, and is convenient to install, guarantee the problem of work efficiency under the prerequisite of lower cost.
Technical solution of the present utility model is:
A kind of expansion sleeve, comprise body, described body is cylindrical body or conical body, described body comprises elasticity claw, pawl groove and clearance groove, described clearance groove is located at the shaft axis of described body, described pawl grooved ring is around described clearance groove setting, and described expansion sleeve is plastic expansion cover or rubber swelling cover.
Further improve and be: the height of described body is 50-60mm, and the degree of depth of described pawl groove is 40-45mm.
Further improve and be: described pawl groove comprises dewclaw groove and lower claw groove, and the notch of described dewclaw groove is located at the upper bottom surface of described body, and the notch of described lower claw groove is located at the bottom surface of described body.
Further improve and be: the bottom land of described pawl groove is sphere.
Further improve and be: filling gel in the described pawl groove.
A kind of expansion sleeve of the utility model in use, at first punches in the mounting point, again with in the expansion sleeve embedding hole, makes to be screwed to get final product.A kind of expansion sleeve of the utility model is easy for installation, and is solid and reliable, is not drawn out easily, and can be widely used in the various installing engineerings.This kind expansion sleeve is made by plastics or rubber, can guarantee good toughness, and it is aging that expansion sleeve also is difficult under the environment of humidity, and overall structure is not loosening, guarantees can use for a long time after installation.Simultaneously, this kind expansion sleeve can adopt cylindrical or conical expansion sleeve for different installation environments, thereby makes expansion sleeve play fixed effect preferably to installation.This kind expansion sleeve good springiness, pulling force is good, and is shock-resistant, do not break, and hardness is strong, and is practical, quick for installation and without problem of rustiness, can prevent this slip after installing, thereby guarantee work efficiency and installation quality.
The beneficial effects of the utility model are: a kind of expansion sleeve of the utility model is easy for installation, solid and reliable, be not drawn out easily, good springiness, pulling force is good, shock-resistant, do not break, hardness is strong, and is practical, quick for installation and without problem of rustiness, this slip after installing be can prevent, thereby work efficiency and installation quality guaranteed.This kind expansion sleeve toughness is high, also is difficult for wearing out under the environment of humidity, and overall structure is loosening, guarantees can use for a long time after installation.
