AI Technical Summary
Technical Problem
The protective structure of bellows in the existing technology is not effective and is easily damaged.
Method used
A protective device is designed, including a protective cover, a first protective sleeve, and a second protective sleeve. The protective cover protects both ends of the bellows, ensuring that the protective sleeve can slide when the bellows deforms. The guide groove and limiting part improve the connection reliability and prevent external debris from entering.
Benefits of technology
It improves the protection of the bellows, reduces the possibility of damage to the protective sleeve, ensures smooth sliding, and extends service life.

Abstract
This application relates to the field of pipe connection technology, and discloses a protective device and pipe equipment. The protective device is used for a bellows. The protective device includes a first connector, a second connector, a protective cover, a first protective sleeve, and a second protective sleeve. The two ends of the protective cover are respectively connected to the first connector and the second connector, forming a protective cavity. The first protective sleeve is disposed in the protective cavity, one end of the first protective sleeve is connected to the first connector, the first protective sleeve defines a first receiving hole for receiving one end of the bellows, and the end of the first protective sleeve opposite to the second connector is connected to one end of the bellows. The second protective sleeve is disposed in the protective cavity, one end of the second protective sleeve is connected to the second connector, the second protective sleeve forms a second receiving hole, the other end of the first protective sleeve extends into the second receiving hole, the second protective sleeve is slidable relative to the first protective sleeve, the second receiving hole is used to receive the other end of the bellows, and the end of the second protective sleeve opposite to the first connector is connected to the other end of the bellows.
