Multiple anti-pull-out socket protection cover

Abstract

The utility model provides a multiple anti-pull-out socket protection cover, and belongs to the technical field of electrical elements. The socket protection cover solves the problem that the possibility that an existing socket protection cover with a handle is pulled out by children is high. The multiple anti-pull-out socket protection cover comprises a cover body, a handle, a blocking sheet and an insulating pin, wherein the blocking sheet comprises a blocking body, a connecting column and a convex column; a strip-shaped connecting hole is formed in the cover body, and the connecting column is inserted into the connecting hole; an annular groove and a strip-shaped groove are formed in the outer end face of the cover body, the strip-shaped groove is located in the longitudinal line of the connecting hole, and the protruding column is embedded into the annular groove or the strip-shaped groove. When the blocking piece of the socket protection cover is in a state of limiting the rotation of the handle, the blocking body is generally in a rotatable state, and the rotation limitation of the handle can be relieved by sliding the blocking piece only when the blocking piece rotates to a state that the convex column directly faces the strip-shaped groove. According to the socket protection cover, the possibility that children correctly operate and pull out the socket protection cover with a handle is reduced by adding the step of operating the blocking sheet and the implementation difficulty.

Description

Technical Field

[0001] This utility model belongs to the field of electrical component technology, and relates to a socket protection cover, particularly a multi-layer anti-pull-out socket protection cover. Background Technology

[0002] Sockets are common electrical components in daily life. Some sockets have exposed sockets, posing a risk of children accidentally inserting their fingers or toys into them, as well as small items falling into them. To mitigate these risks, various socket protection structures have been proposed. For example, the socket protective cover described in Chinese patent literature (authorization announcement number CN205565089U) is inserted into the socket during use, with the handle hidden in a groove in the cover. While this design reduces the possibility of children directly contacting the metal contacts inside the socket, it also presents the problem that children can easily pull it out.

[0003] To address this, various technical solutions have been proposed to reduce the risk of children pulling out power socket protective covers. For example, a power socket protective cover (authorization announcement number CN205752688U) described in Chinese patent literature has a sliding piece on the cover that can block the handle. That is, the sliding piece must be pushed open first before the handle can be turned and pulled out.

[0004] For example, a socket protective cover described in Chinese patent literature (authorization announcement number CN207474760 U) has a rotatable baffle on the cover that can block the handle. That is, the baffle must be rotated first to make the baffle misalign with the handle before the handle can be rotated and pulled out.

[0005] Perhaps because the handle obstruction structure is visible, most children are still able to operate the socket correctly and pull out the protective cover. Summary of the Invention

[0006] This invention proposes a multi-layered anti-pull-out socket protective cover. The technical problem this invention aims to solve is how to reduce the likelihood of children correctly pulling out the socket protective cover with a handle.

[0007] The technical problem to be solved by this utility model can be achieved through the following technical solution: A multi-layer anti-pull-out socket protective cover, comprising a cover body, a handle, and a blocking plate, wherein an insulated plug pin that can be inserted into a socket hole is fixedly connected to the cover body, the handle is rotatably connected to the cover body via a shaft, and a groove adapted to the handle is provided on the cover body, the handle being able to be embedded in the groove; characterized in that the blocking plate comprises a blocking body, a connecting post connected to the central area of ​​the back of the blocking body, and a protruding post located on one side of the connecting post and connected to the back of the blocking body; a strip-shaped... The connecting hole is into which the connecting post is inserted; an annular groove and a strip groove connected to the annular groove are provided on the outer end face of the cover. The strip groove is located on the longitudinal line of the connecting hole. The protruding post is embedded in the annular groove or the strip groove. When the protruding post is embedded in the annular groove, the blocking body prevents the handle located in the groove from rotating and the blocking body can rotate relative to the cover. When the protruding post is directly opposite the strip groove, the blocking plate can slide relative to the cover along the longitudinal line of the connecting hole, the protruding post slides into the strip groove, and the blocking body releases the restriction on the rotation of the handle located in the groove.

[0008] Compared to existing technologies, in this socket protective cover, when the blocking plate is in the state that restricts the rotation of the handle, the blocking body is usually in a rotatable state. Only when the protrusion and the slot are aligned can the rotation restriction be released by sliding the blocking plate. Both the protrusion and the slot are blocked by the blocking body, and it is not visible whether the protrusion and the slot are aligned, further increasing the difficulty of releasing the rotation restriction.

[0009] From the handle rotation restriction state to the handle rotation restriction release state, this socket protective cover reduces the likelihood of children correctly pulling out the socket protective cover with the handle by adding an operation blocking piece and making it more difficult to implement.

[0010] In the aforementioned multi-layer anti-pull-out socket protection cover, the blocking plate is an integral structure, the connecting post is cylindrical, and one end of the connecting post has a barb; the barb engages with the inner end face of the cover and the blocking body engages with the outer end face of the cover to restrict the axial movement of the blocking plate.

[0011] In the aforementioned multi-layer anti-pull-out socket protection cover, the blocking plate is a split structure, with the connecting post and the blocking body rotatably connected by a shaft.

[0012] In the aforementioned multi-layer anti-pull-out socket protection cover, the protrusion is cylindrical, and the connection between the annular groove and the strip groove is transitioned by a rounded chamfer.

[0013] In the aforementioned multi-layer anti-pull-out socket protection cover, a handle is installed on the outer side of the blocking body. Attached Figure Description

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0027] Example 1: As Figures 1 to 8 As shown, a multi-layer anti-pull-out socket protective cover includes a cover body 1, a handle 2, and a blocking plate 3. Insulated pins 4 that can be inserted into the socket holes are fixedly connected to the cover body 1. The number of insulated pins 4 is usually 2 or 3.

[0028] The handle 2 is roughly U-shaped and has a shaft. The cover 1 has a groove 1a that matches the handle 2. The side wall of the groove 1a has a shaft hole. The shaft is inserted into the shaft hole, so that the handle 2 and the cover 1 are rotatably connected. Swinging the handle 2 can make the handle 2 be in the state of being embedded in the groove 1a, or it can make the handle 2 be in a state perpendicular to the outer end face of the cover 1. This state is suitable for pulling out the socket protective cover.

[0029] The blocking plate 3 is a one-piece structure, including a disc-shaped blocking body 3a, a connecting post 3b connected to the central area of ​​the back of the blocking body 3a, and a protruding post 3c located on one side of the connecting post 3b and connected to the back of the blocking body 3a. The connecting post 3b is cylindrical, and one end of the connecting post 3b has a barb.

[0030] A strip-shaped connecting hole 1b is provided on the cover 1, and a connecting post 3b is inserted into the connecting hole 1b; the width of the connecting hole 1b is adapted to the diameter of the connecting post 3b. The barb part cooperates with the inner end face of the cover 1, and the blocking body 3a cooperates with the outer end face of the cover 1 to limit the axial movement of the blocking piece 3. An annular groove 1c located outside the connecting hole 1b and a strip groove 1d connected to the annular groove 1c are provided on the outer end face of the cover 1. The strip groove 1d is located on the longitudinal line of the connecting hole 1b, and the protruding post 3c is embedded in the annular groove 1c or the strip groove 1d.

[0031] The protruding post 3c is cylindrical, and the connection between the annular groove 1c and the strip groove 1d is transitioned by a rounded chamfer 1e, thereby improving the smoothness of the protruding post 3c sliding from the annular groove 1c into the strip groove 1d and from the strip groove 1d into the annular groove 1c. A handle 3d is installed on the outer surface of the blocking body 3a for easy access.

[0032] The blocking body 3a applies force, while the handle 3d also serves as a marker and directional element, allowing the operator to determine whether the protrusion 3c is aligned with the groove 1d based on the position of the handle 3d. Depending on the specific circumstances, other markings can be added to the cover 1, handle 2, and blocking plate 3, such as the arrows on the handle 2 and blocking plate 3 shown in the attached diagram.

[0033] By explaining the usage process of the socket protective cover, the function and advantages of each component are further illustrated. For example... Figures 1 to 3 As shown, the handle 2 is located in the groove 1a, the protrusion 3c is embedded in the annular groove 1c, and the blocking body 3a is located above the handle 2, partially overlapping it, so the handle 2 is in a rotation-restricted state. In this state, the connecting post 3b is located in one end area of ​​the connecting hole 1b, and the blocking body 3a can rotate around the center line of the connecting post 3b relative to the cover 1.

[0034] The process from the state of restricted rotation of handle 2 to the state of release of restricted rotation of handle 2 is as follows: First, rotate the blocking plate 3 and infer from the position of handle part 3d or the position of the mark that the protrusion 3c and the strip groove 1d are aligned. Then push the blocking plate 3 to move. The blocking body 3a also blocks the connecting hole 1b. The longitudinal direction of the connecting hole 1b is not visible. Operators need to determine the direction of force applied to push the blocking plate 3 based on common sense. The attached diagram of the instruction manual shows that the moving direction of the blocking plate 3 is set perpendicular to the horizontal part of the handle 2. The blocking plate 3 slides along the longitudinal direction of the connecting hole 1b relative to the cover 1. The connecting post 3b moves to the other end area of ​​the connecting hole 1b. During this process, the protrusion 3c slides into the strip groove 1d, the blocking body 3a and the handle 2 no longer coincide, and the blocking body 3a releases the rotation restriction of handle 2 located in the groove 1a. Figures 4 to 6 As shown, handle 2 has been rotated to a position perpendicular to the front end face of cover 1.

[0035] Example 2: This example is basically the same as Example 1 in structure and principle. The similarities will not be described again. Only the differences will be described. The difference is that the blocking plate 3 is a split structure, the connecting column 3b is square column-shaped, and the connecting column 3b is rotatably connected to the blocking body 3a by an axis; thus, the blocking body 3a rotates around the center line of the aforementioned axis.
