The cross section of the cylinder 11 is circular, and when the cylinder 11 is sleeved outside the connecting sleeve 21, the inner circumferential surface of the cylinder 11 is attached to the outer circumferential surface of the connecting sleeve 21.
According to the technical scheme, the special protective cover for the connecting sleeve is provided, the protective cover can be used after being sleeved, the operation is simple, the protective effect is good, and the appearance is attractive.
In the present invention, in order to improve the reliability of the combination of the shield 10 and the connection sleeve 21 and prevent the shield 10 from coming off the connection sleeve 21, the two sides of the slot 111 of the cylinder 11 can be respectively connected with the clamping arms 113, and the two clamping arms 113 can clamp the connection sleeve 21 when the cylinder 11 is sleeved on the connection sleeve 21.
The clamping arm 113 may have various embodiments as long as it can clamp the connecting sleeve 21. For example, two clamping arms 113 may extend from two sides of the slot 111 towards the inside of the barrel 11 in a manner deviating from the circumferential direction of the barrel 11, respectively, so as to form a closed opening in the circumferential profile of the barrel 11; two clip arms 113 may also extend tangentially outward from both side edges of the slot 111 in the circumferential direction of the barrel 11, respectively, to form a closed-off in the circumferential profile of the barrel 11 (see fig. 1 and 2).
The clamping arm 113 may extend along the entire axial length of the barrel 11, the length of the clamping arm 113 may also be smaller than the axial length of the barrel 11, and each side of the slot 111 may also include a plurality of clamping arms 113 disposed at intervals.
In addition, as shown in fig. 1 and 2, the outer edge of the clamping arm 113 may be provided with a thickened portion to improve the strength of the shield and improve the clamping force of the clamping arm 113.
It should be noted that, in some embodiments, the protective hood 10 may also be directly adhered to the connecting sleeve by using a wear-resistant self-adhesive material instead of the clamping arms 113.
In the present invention, the other end of the cylindrical body 11 may be open or closed. In order to further improve the protection of the connection sleeve 21 and the reliability of the combination of the protection cover 10 and the connection sleeve 21, the other end of the cylinder 11 is preferably closed.
Specifically, as shown in fig. 1 and fig. 2, the protecting cover 10 may further include an end cap 12 disposed at the other end of the cylinder 11, and when the protecting cover 10 is sleeved on the connecting sleeve 21, the end cap 12 is tightly attached to the corresponding end surface of the connecting sleeve 21.
