Through having seted up first opening 110a at cover body 110, and be equipped with magnetic part 140 in cover body 110, when cover body 110 rotates to first rotation position, first opening 110a can be relative with second opening 211, then make magnetic part 140 be close to latch hook main part 220 in latch hook assembly 200 more, then attract latch hook main part 220 motion and stretch out second opening 211, through first opening 110a towards being close to the direction motion of magnetic part 140, until inhale with magnetic part 140, the closure effect of hinge cover assembly 100 and latch hook assembly 200 has been realized, the user only needs to drive cover body 110 and rotates to first rotation position, can be convenient for attract latch hook main part 220 to stretch out second opening 211 automatically in order to lock with hinge cover assembly 100, this closure process is convenient for operation, it is comparatively convenient. In addition, when the cover body 110 rotates to the second rotation position, the first opening 110a is far away from the second opening 211, so that the magnetic element 140 is gradually far away from the latch hook main body 220, and the latch hook main body 220 loses the attraction of the magnetic element 140, so that the latch hook main body 220 is conveniently stored in the embedded box 210 again, and the latch hook assembly 200 is prevented from scratching or colliding other components when a user opens and closes the door.

In an example, referring to fig. 3, 4 and 6, the latch hook main body 220 is hinged to the pre-buried box 210, and the rotating shaft 230 of the latch hook main body 220 is connected to the pre-buried box 210, and the latch hook main body 220 can rotate around the rotating shaft 230 to extend out of the second opening 211 or be accommodated in the pre-buried box 210.

In this example, the latch hook main body 220 is hinged to the pre-buried box 210, and the rotating shaft 230 of the latch hook main body 220 is connected to the pre-buried box 210, so that the latch hook main body 220 can be accommodated in the pre-buried box 210 when rotating around the rotating shaft 230, so as to avoid scratching other components in the door opening and closing process when the latch hook main body 220 is mounted on the door body; or can extend at least partially beyond the pre-buried box 210 during rotation to allow the hinge cover assembly 100 to be attracted to lock in a closed position. By hinging the latch hook main body 220 with the pre-buried box 210, the latch hook main body 220 is conveniently accommodated in the pre-buried box 210 or extends out from the pre-buried box 210.

Specifically, in order to achieve the effect that the latch hook main body 220 is hinged to the pre-buried box 210, the latch hook main body 220 may be installed at the second opening 211, and then the rotating shaft 230 is inserted through the pre-buried box 210 and the latch hook main body 220, so that the latch hook main body 220 can rotate around the rotating shaft 230, and the latch hook main body 220 can extend out of the second opening 211 or be accommodated in the pre-buried box 210. Further, in order to reduce the risk that the latch hook main body 220 is worn and frequent replacement of the latch hook main body 220 is required, a through hole is formed in the latch hook main body 220 for the spindle 230 to pass through, a bushing is pre-installed in the through hole, and then the spindle 230 passes through the bushing. In addition, after the rotating shaft 230 passes through the lock hook main body 220 and the embedded box 210, in order to axially limit the rotating shaft 230, a clamp spring may be installed on the rotating shaft 230 to limit the axial movement of the rotating shaft 230.

Further, referring to fig. 3, 4 and 6 in combination, the center of gravity of the latch hook main body 220 is located at a side of the rotating shaft 230 away from the second opening 211, so that when the cover main body 110 rotates to the second rotation position, the latch hook main body 220 rotates by itself under the action of gravity and is accommodated in the pre-buried box 210.

By locating the center of the latch hook main body 220 at the side of the rotating shaft 230 far away from the second opening 211, after the latch hook main body 220 is separated from the attraction of the magnetic member 140, the latch hook main body 220 can automatically turn around the rotating shaft 230 to the inside of the embedded box 210 due to the influence of gravity, so as to achieve the effect that the latch hook main body 220 can be accommodated in the embedded box 210. By the arrangement, the latch hook main body 220 in the latch hook assembly 200 can be automatically accommodated into the embedded box 210 without arranging the elastic piece on the latch hook assembly 200, so that the latch hook assembly 200 has fewer components and simpler structure.

Of course, in order to achieve the effect that the latch hook main body 220 can be automatically received in the pre-buried box 210 without considering the complexity of the structure, the latch hook assembly 200 may further include an elastic member (not shown), wherein the elastic member is disposed in the pre-buried box 210, one end of the elastic member is connected to the latch hook main body 220, the other end of the elastic member is connected to the pre-buried box 210, and when the cover body 110 rotates to the second rotation position, the elastic member pulls the latch hook assembly 200, so that the latch hook assembly 200 is automatically received in the pre-buried box 210.

When the elastic member is disposed in the pre-buried box 210, one end of the elastic member is connected to the latch hook main body 220, and the other end is connected to the pre-buried box 210. The elastic member may be a spring, and an extending direction of the elastic member may be parallel to an opening direction of the second opening 211, and one end of the elastic member is connected to the latch hook assembly 200, and the other end of the elastic member is connected to a side wall of the pre-buried box 210 opposite to the second opening 211. By this arrangement, the latch hook main body 220 can be in any shape, as long as the latch hook main body can extend out of the embedded box 210 under the attraction of the magnetic element 140 and attract the magnetic element 140, and can be completely accommodated in the embedded box 210 under the tensile force of the elastic element after being separated from the magnetic element 140. Or, based on the scheme that the latch hook main body 220 is hinged to the embedded box 210, one end of the elastic member is connected to the bottom of the embedded box 210, and the other end of the elastic member is connected to the latch hook main body 220.
