Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a locking mechanism of a shaft protection cover comprises a first shield 1, a second shield 2 and a plurality of locking components 3, wherein the lower parts of the first shield 1 and the second shield 2 are rotatably connected through a pin shaft 4, the locking components 3 comprise a plurality of sockets 5 which are sequentially arranged at intervals at the top parts of the first shield 1 and the second shield 2, a lock catch 6 which spans the first shield 1 and the second shield 2 is inserted into the sockets 5, a positioning hole 7 is arranged at the upper part of the joint of the first shield 1 and the second shield 2 on the lock catch 6, a fixing plate 8 is arranged on the second shield 2, a fastening bolt 9 is arranged on the fixing plate 8, a locking block 10 which can slide along the fastening bolt 9 is further arranged on the fixing plate 8, a sliding groove 11 for the fastening bolt 9 to be inserted into is arranged on the locking block 10, the locking block 10 comprises a plurality of inserting plates 12 which can be inserted into the positioning hole 7 of the lock catch 6, the lock catch 6 is correspondingly provided with a U-shaped groove 13 at the joint of the first shield 1 and the second shield 2.

The locking mechanism of a shaft protection cover of this scheme, it can carry out the locking with first guard shield 1 and second guard shield 2, in the use, when first guard shield 1 and second guard shield 2 closed, insert all hasps 6 in the socket 5 in proper order, it needs to be noted, as shown in the attached drawing, the direction of hasp 6 is according to the difference of socket 5 on first guard shield 1 and second guard shield 2 and distinguish, all be provided with a reference column that can insert in socket 5 on every hasp 6, socket 5 interval sets up on first guard shield 1 and second guard shield 2, the benefit that sets up like this can make 6 cooperation picture pegs of hasp 12 carry out spacing fixed with first guard shield 1 and second guard shield 2, can prevent that first guard shield 1 and second guard shield 2 from scattering.
