Abstract

The utility model provides a multiple anti-pull-out socket protective cover, and belongs to the technical field of electric elements. The socket protecting cover solves the problem that the existing socket protecting cover with the handle has high possibility of being pulled out by children. The multi-pull-out-preventing socket protective cover comprises a cover body, a handle, a blocking piece and an insulating pin, wherein the blocking piece comprises a blocking body, a connecting column and a convex column, the cover body is provided with a strip-shaped connecting hole, the connecting column is inserted into the connecting hole, the outer end face of the cover body is provided with an annular groove and a strip-shaped groove, the strip-shaped groove is positioned on a longitudinal line of the connecting hole, and the convex column is embedded into the annular groove or the strip-shaped groove. When the blocking piece of the socket protective cover is in a state of limiting the rotation of the handle, the blocking body is usually in a rotatable state, and the rotation limitation of the handle can be relieved through sliding the blocking piece only when the blocking body rotates to a state that the convex column is opposite to the strip-shaped groove. The socket protecting cover reduces the possibility that a child correctly operates and pulls out the socket protecting cover with the handle by adding the step of operating the blocking piece and realizing difficulty.

Description

Multiple anti-pull-out socket protective cover Technical Field The utility model belongs to the technical field of electrical elements, and relates to a socket protection cover, in particular to a multiple anti-pull-out socket protection cover. Background The socket is the electrical component commonly seen in life, and the jack of partial socket exposes, and children's finger and handheld toy all have the risk of unexpected insertion in the jack to and little article has the risk of unexpected falling into in the jack, in order to reduce above-mentioned risk, people have proposed multiple jack protection architecture. The socket protecting cover (authorized bulletin number CN 205565089U) disclosed in Chinese patent document is inserted into the jack when in use, and the handle is hidden in the groove of the cover body, so that the possibility that a child directly contacts the metal sheet in the jack is reduced, but the problem that the child is easy to pull out the socket protecting cover is solved. For this reason, various technical schemes for reducing the pulling-out of the socket protecting cover by children have been proposed, such as a power socket protecting cover (authorized bulletin number CN 205752688U) described in chinese patent literature, and a sliding sheet capable of blocking the handle is slidably disposed on the cover body, that is, the sliding sheet needs to be pushed open first, and then the handle is turned and pulled out. In another example, a protective cover (CN 207474760U) for a socket is disclosed in chinese patent literature, a blocking piece capable of blocking the handle is rotatably disposed on the cover body, that is, the blocking piece needs to be rotated first to make the blocking piece dislocate with the handle, and then the handle is rotated and pulled out. Most children still operate properly and pull out the socket protective cover, perhaps due to the visible pull-tab blocking structure. Disclosure of Invention The utility model provides a multiple anti-pull-out socket protective cover, which aims to solve the technical problem of reducing the possibility of pulling out the socket protective cover with a handle when a child operates correctly. The technical scheme is that the multi-pull-out-prevention socket protective cover comprises a cover body, a handle and a blocking piece, wherein an insulation pin capable of being inserted into a socket jack is fixedly connected to the cover body, the handle is connected with the cover body through shaft rotation, a groove matched with the handle is formed in the cover body, the handle can be embedded in the groove, the multi-pull-out-prevention socket protective cover is characterized in that the blocking piece comprises a blocking body, a connecting column connected with the central area of the back of the blocking body, a protruding column located on one side of the connecting column and connected with the back of the blocking body, a strip-shaped connecting hole is formed in the cover body, the connecting column is inserted into the connecting hole, an annular groove located on the outer side of the connecting hole and a strip-shaped groove communicated with the annular groove are formed in the outer end face of the cover body, the strip-shaped groove is located on the longitudinal line of the connecting hole, the handle is embedded in the annular groove or the strip-shaped groove, when the protruding column is embedded in the annular groove, the blocking body is blocked to rotate in the groove and the blocking body can rotate relative to the cover body, and when the protruding column and the protruding column is right relative to the groove, the blocking piece can slide along the longitudinal line of the connecting hole, and the blocking body is located in the sliding groove and the blocking body is released from being located in the groove. Compared with the prior art, when the blocking piece of the socket protective cover is in a state of limiting the rotation of the handle, the blocking body is usually in a rotatable state, and the rotation limitation of the handle can be relieved through the sliding blocking piece only when the blocking piece rotates to a state that the convex column is opposite to the strip-shaped groove. The convex columns and the strip-shaped grooves are all shielded by the blocking body, and whether the convex columns and the strip-shaped grooves are in a dead-facing state or not is invisible, so that the difficulty of relieving rotation restriction is further improved. From the handle rotation limiting state to the handle rotation limiting state releasing state, the socket protecting cover reduces the possibility that a child correctly operates and pulls out the socket protecting cover with the handle by increasing the steps of operating the blocking piece and realizing difficulty. In the multi-pull-out prevention socket protective cover, the blocking piece is of an integrated structure, the connec
