Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The socket is a common electronic device, and is used for plugging a plug of an electrical appliance so as to supply power to the electrical appliance.

In the related art, there is an embedded socket, which is mostly embedded in a carrier such as a desk, a cabinet, etc., and only exposes a jack for plugging a plug of an electrical appliance. Compared with a common socket, the embedded socket saves space and is more attractive. However, the embedded socket is embedded in the carrier and cannot be moved, and if a container containing liquid, such as a cup or a vase on the carrier, is knocked over, the liquid is very easy to flow into the socket from the jack, so that electronic parts inside the socket are short-circuited, and the socket is damaged.

In order to solve the above technical problem, an embodiment of the present disclosure provides a protective cover, fig. 1 is an exploded view of the protective cover, and as shown in fig. 1, the protective cover includes a base 1, a sliding cover 2, and a sealing structure 3.

The base 1 comprises a bottom plate 11 and a fixed enclosing plate 12, wherein the bottom plate 11 is provided with an inserting through hole 111, the inserting through hole 111 penetrates through the bottom plate 11, and the fixed enclosing plate 12 extends along the circumferential direction of the outer edge of the bottom plate 11 and is connected with the bottom plate 11. The sliding cover 2 is slidably sleeved outside the base 1, and the sliding cover 2 is in sliding fit with the fixed enclosing plate 12. The sealing structure 3 is sleeved on the fixed enclosing plate 12 and clamped at the joint between the fixed enclosing plate 12 and the sliding cover 2.

Fig. 2 is an assembly diagram of the shield cover and the socket body, and with reference to fig. 2, when the shield cover provided by the embodiment of the present disclosure is used to protect the socket, the bottom plate 11 is connected to the socket body 200, so that the insertion holes 201 of the socket body 200 are opposite to the insertion through holes 111 of the bottom plate 11, thereby completing the installation between the shield cover and the socket body 200.

Fig. 3 is a schematic structural diagram of a closed state of the protective cover, and referring to fig. 3, when the socket is idle, the sliding cover 2 is sleeved outside the base 1 and is in sliding fit with the fixed surrounding plate 12 of the base 1, and the inserting through hole 111 of the bottom plate 11 and the inserting hole 201 of the socket body 200 can be shielded by the sliding cover 2, so that liquid is prevented from directly flowing into the socket body 200. Further, the sealing structure 3 is arranged at the joint between the sliding cover 2 and the fixed enclosing plate 12, so that even if liquid splashes on the sliding cover 2, the liquid cannot further seep from the joint between the sliding cover 2 and the fixed enclosing plate 12, the sealing performance between the sliding cover 2 and the base 1 is ensured, and the protection effect of the protective cover on the socket body 200 is improved.

Fig. 4 is an opening state structure diagram of the protective cover, and with reference to fig. 4, when the socket is needed to be used, the sliding cover 2 is moved, so that the sliding cover 2 is moved on the base 1 until the plugging through hole 111 and the jack 201 are exposed, so that the plug of the electrical appliance can pass through the plugging through hole 111 to be plugged into the jack 201, and then normal electricity taking is realized.

That is to say, when the socket is idle, the sliding cover 2 can be used to cover the insertion hole 201, so as to prevent the liquid from directly entering the socket body 200 through the insertion hole 201. In addition, by using the sealing structure 3 between the sliding cover 2 and the base 1, the liquid can be further ensured not to be infiltrated into the gap between the sliding cover 2 and the base 1, thereby improving the protection effect of the protective cover. When the socket is needed, the sliding cover 2 is moved to expose the jack 201, so that the plug of the electrical appliance can normally take electricity. After the power is taken out, the sliding cover 2 is moved reversely, so that the sliding cover 2 covers the jack 201 again to play a role in preventing water again.

It is easy to understand that the protective cover not only has the function of water resistance, but also has the functions of dust prevention, foreign matter prevention, children electric shock prevention and the like.

From the foregoing, the sealing structure 3 and the sliding cover 2 play a key role in the waterproof effect of the protective cover. The sealing structure 3 and the slide cover 2 will be described separately below.

Fig. 5 is a schematic view of the arrangement of the sealing structure on the base, and in conjunction with fig. 5, in the present embodiment, the sealing structure 3 includes a first sealing strip 31, the first sealing strip 31 is located on the outer side surface of the positioning and enclosing plate 12, and the first sealing strip 31 extends circumferentially along the outer side surface of the positioning and enclosing plate 12.

Because the lateral surface of the fixed surrounding plate 12 is a part which is in sliding fit with the sliding cover 2, the first sealing strip 31 extends along the circumferential direction of the lateral surface of the fixed surrounding plate 12, namely, the first sealing strip is wound along the lateral surface of the fixed surrounding plate 12, the lateral surface of the fixed surrounding plate 12 can be sealed in all directions, and liquid is prevented from permeating from the fit position between the lateral surface of the fixed surrounding plate 12 and the sliding cover 2.

Illustratively, the two ends of the first sealing strip 31 are connected to form a ring shape, so that the first sealing strip 31 can be sleeved on the outer side surface of the fixed wall plate 12, and the installation of the first sealing strip 31 on the fixed wall plate 12 is facilitated. In addition, the outer side surface of the fixed enclosing plate 12 is provided with a sealing groove matched with the first sealing strip 31, so that the first sealing strip 31 can be stably sleeved on the fixed enclosing plate 12.

With continued reference to fig. 5, in this embodiment, the sealing structure 3 further includes a second sealing strip 32, a part of the second sealing strip 32 is located on the outer side surface of the positioning wall 12, another part is located on the top edge of the positioning wall 12, and the top edge of the positioning wall 12 is an edge facing away from the bottom plate 11.

Because the top edge of the fixed enclosing plate 12 is a part which is in sliding fit with the sliding cover 2, part of the second sealing strip 32 is arranged on the top edge of the fixed enclosing plate 12, so that the top edge of the fixed enclosing plate 12 can be sealed, and liquid is prevented from permeating from a joint between the top edge of the fixed enclosing plate 12 and the sliding cover 2. In addition, since a part of the second weather strip 32 is arranged on the outer side surface of the fixed wall 12, the outer side surface of the fixed wall 12 can be further sealed by the second weather strip 32.

It will be readily appreciated that the sealing strip has a better sealing ability against liquid penetrating in a direction substantially perpendicular to itself and a lower sealing ability against liquid penetrating in a direction substantially parallel to itself, and that, in order to ensure that the sealing structure 3 can seal against liquid in all directions, optionally, the portion of the second sealing strip 32 located on the outer side of the retainer plate 12 is perpendicular to the first sealing strip 31. That is to say, the first sealing strip 31 and the second sealing strip 32 are partially vertically arranged, so that the liquid can be hermetically sealed in all directions through the matching between the first sealing strip 31 and the second sealing strip 32, and dead sealing angles are eliminated.

Illustratively, both ends of the second sealing strip 32 are respectively connected with the first sealing strip 31, and the second sealing strip 32 and the first sealing strip 31 are of an integral structure. Therefore, the first sealing strip 31 and the second sealing strip 32 are integrated, so that the gap can be effectively reduced, and the sealing effect of the sealing structure 3 is ensured.

Illustratively, the first sealing strip 31 and the second sealing strip 32 are both rubber structural members and are combined with the base 1 through processes of secondary injection molding, encapsulation and the like, so that the sealing structure 3 can improve the manufacturing efficiency and reduce the manufacturing cost.

It is easy to understand that, in the case that the first sealing strip 31 and the second sealing strip 32 are an integral structural member, the sealing grooves for accommodating the first sealing strip 31 and the second sealing strip 32 also correspond to an integral groove, that is, they are communicated with each other to form a whole, so that the first sealing strip 31 and the second sealing strip 32 can be accommodated better.

The sealing structure 3 is described above, and a manner of sealing the joint between the base 1 and the sliding cover 2 by the sealing structure 3 is described below in conjunction with the base 1 and the sliding cover 2.

Fig. 6 is a schematic structural diagram of the sliding cover, and in order to show the inner side structure of the sliding cover 2, the viewing angle of fig. 6 is opposite to that of fig. 1, that is, fig. 6 is a bottom view of the sliding cover 2.

Referring to fig. 6, in the present embodiment, the slide cover 2 includes a cover plate 21, a moving fence 22, and an opening 23. The length direction of the cover plate 21 is the same as the moving direction of the sliding cover 2; the movable enclosing plate 22 extends along the circumferential direction of the outer edge of the cover plate 21 and is connected with the cover plate 21, and the movable enclosing plate 22 is in sealing contact with the first sealing strip 31 and the second sealing strip 32 respectively; the opening 23 is located on the moving enclosing plate 22, and corresponds to the end of the cover plate 21 in the length direction, the opening 23 penetrates through the moving enclosing plate 22 to provide an inserting space for the base 1, and the opening 23 is in sealing contact with the second sealing strip 32.

In the above implementation manner, when the sliding cover 2 is sleeved on the base 1, the cover plate 21 is opposite to and spaced from the bottom plate 11, the cover plate 21 is opposite to and attached to the top edge of the fixed enclosing plate 12, and the movable enclosing plate 22 is opposite to and attached to the outer side surface of the fixed enclosing plate 12. That is, the joint between the slide cover 2 and the fixed enclosing plate 12 includes the joint between the top edge of the cover plate 21 and the fixed enclosing plate 12, and the joint between the movable enclosing plate 22 and the outer side surface of the fixed enclosing plate 12. It should be noted that although the cover plate 21 is attached to the top edge of the whole fixed enclosing plate 12, since the attachment of the cover plate 21 to the top edge of the fixed enclosing plate 12 is closer to the inside, most of the attachment is already sealed by the first sealing strip 31, and only the position corresponding to the opening 23 is exposed, so that only sealing is needed.

When sealed by the sealing structure 3, the sealing between the cover plate 21 and the top edge of the fixed enclosing plate 12, namely the sealing at the opening 23, is realized by the part of the second sealing strip 32 positioned on the top edge of the fixed enclosing plate 12, and the sealing between the movable enclosing plate 22 and the outer side surface of the fixed enclosing plate 12 is realized by the matching of the first sealing strip and the part of the second sealing strip 32 positioned on the outer side surface of the fixed enclosing plate 12.

When the sliding cover 2 is installed on the base 1, the opening 23 is aligned to one end of the base 1, the cover plate 21 is attached to the top edge of the fixed enclosing plate 12, the movable enclosing plate 22 is attached to the outer side surface of the fixed enclosing plate 12, and the sliding cover 2 is sleeved on the base 1 along the length direction of the base 1, so that the installation of the sliding cover 2 on the base 1 is completed.

The two sides of the moving surrounding plate 22 in the length direction are respectively opposite to the two sides of the fixed surrounding plate 12 in the length direction and are in sliding fit, and the end part of the moving surrounding plate 22 far away from the opening 23 in the length direction is opposite to the end part of the fixed surrounding plate 12 far away from the opening 23 in the length direction but is not in sliding fit. And therefore requires enhanced sealing, the slide cover 2 further comprises a sealing boss 24, for example. The sealing boss 24 is located on the moving enclosing plate 22, and corresponds to the end of the cover plate 21 away from the opening 23 in the length direction, one end of the sealing boss 24 is connected with the moving enclosing plate 22, and the other end protrudes toward the opening 23. The sealing structure 3 further comprises a third sealing strip 33, and the third sealing strip 33 is sleeved on the sealing boss 24 and is located between two ends of the sealing boss 24.

In the above implementation, the sealing boss 24 provides a mounting base for the third sealing strip 33, so that the sealing between the sliding cover 2 and the base 1 can be enhanced by the third sealing strip 33.

Fig. 7 is a longitudinal sectional view of the shield, i.e. a sectional view in the length direction of the shield, and with reference to fig. 7, in order to further cooperate with the sealing boss 24 and the third sealing strip 33, optionally, the base 1 further includes a notch 13, the notch 13 is located on the positioning and enclosing plate 12, and corresponds to the end portion of the bottom plate 11 in the length direction, the notch 13 penetrates through the positioning and enclosing plate 12 to accommodate the sealing boss 24, and the notch 13 is in sealing contact with the third sealing strip 33.

When the protective cover is in the closed state, the sealing boss 24 is inserted into the notch 13, so that the third sealing strip 33 is clamped between the sealing boss 24 and the notch 13, and the sealing performance between the sliding cover 2 and the base 1 can be enhanced through the sealing boss 24 and the third sealing strip 33.

It should be noted that if the base 1 does not include the notch 13, the protruding length of the sealing boss 24 away from the moving enclosing plate 22 is also reduced, and only enough installation base for the third sealing strip 33 needs to be provided.

From the foregoing, the shield can be in the open state or the closed state by moving the slide cover 2. Fig. 8 is a partial sectional view of the shield in a closed state, and fig. 9 is a partial sectional view of the shield in an open state, and in fig. 8 and 9, the cover plate 21 is cut away to show other parts between the cover plate 21 and the base plate 11.

In order to improve the convenience of the user to move the sliding cover 2, in the present embodiment, the protective cover further includes a driving assembly 4 and a locking assembly 5, in conjunction with fig. 8 and 9.

The driving assembly 4 is located between the base 1 and the sliding cover 2, and is connected to the base 1, and the driving assembly 4 is configured to drive the sliding cover 2 to move along the length direction of the base 1 when the protective cover is in an open state. The locking assembly 5 is located between the base 1 and the sliding cover 2 and is connected with the base 1 and the sliding cover 2 respectively, and the locking assembly 5 is configured to keep the protective cover in a closed state.

In the above implementation, when the protection casing is in the closed state, under the effect of locking subassembly 5, if there is not user's operation, the protection casing can remain at the closed state always to guarantee that the protection casing continuously plays waterproof protection's effect. When the protective cover needs to be changed from the closed state to the open state, a user operates the sliding cover 2, so that the protective cover is changed to the open state, the locking of the locking assembly 5 is released, and in this case, the driving assembly 4 can further drive the sliding cover 2 to move along the length direction of the base 1 until the protective cover is completely opened. Therefore, when the protective cover is opened, a user only needs to move the sliding cover 2 in a short distance, the protective cover is changed from a closed state to an opened state, then the sliding cover 2 can automatically slide under the action of the driving assembly 4 until the protective cover is completely opened, and convenience of moving the sliding cover 2 by the user is improved.

With continued reference to fig. 8 and 9, in the present embodiment, the drive assembly 4 includes a first pin 41, a second pin 42, and a resilient member 43.

The first pin 41 is located at an end of the bottom plate 11 in the length direction, one end of the first pin 41 is connected to a plate surface of the bottom plate 11 facing the sliding cover 2, and the other end extends toward the sliding cover 2. The second pin 42 is located at an end of the sliding cover 2 in the length direction, and is far away from the first pin 41, one end of the second pin 42 is connected to a plate surface of the sliding cover 2 facing the bottom plate 11, and the other end extends toward the bottom plate 11. The elastic member 43 is connected to the first pin 41 and the second pin 42, respectively.

It should be noted that, since the cover plate 21 is cut away in fig. 8 and 9, the connection relationship between the second pin 42 and the cover plate 21 cannot be exhibited, and the second pin 42 seems to be connected to the base plate 11 due to the view angle. In fact, the second pin 42 is spaced from the bottom plate 11 without a connection, and the connection between the second pin 42 and the cover plate 21 can be clearly understood by referring to fig. 6.

When the hood is in the closed state, the elastic member 43 is held in a stretched state between the first pin 41 and the second pin 42 by the locking assembly 5. When a user operates the sliding cover 2 to make the protective cover change to an open state so as to release the locking of the locking assembly 5, under the elastic force of the elastic member 43, the first pin 41 and the second pin 42 are pulled to move towards each other, and then the sliding cover 2 is driven to move along the length direction of the base 1 until the protective cover is completely opened.

To ensure that the opening of the shield is large enough to expose all of the insertion holes 201, the first pin 41 is located on the bottom plate 11 near the notch 13, and the second pin 42 is located on the cover plate 21 near the opening 23.

Alternatively, the elastic member 43 is a clockwork spring wound around the first pin 41. Because the clockwork spring can be wound on the first pin 41, the installation space can be saved, and the plug jack 201 is prevented from being influenced.

In the present embodiment, the locking assembly 5 includes a locking groove 51 and a locking protrusion 52. The locking groove 51 is located on the sliding cover 2 (see fig. 6), the locking protrusion 52 is located on the base 1 (see fig. 5) and opposite to the locking groove 51, and when the protective cover is in the closed state, the locking protrusion 52 is clamped in the locking groove 51.

In the above implementation, the locking protrusion 52 and the locking groove 51 are engaged with each other to overcome the elastic force of the elastic member 43, so that the shield can be maintained in the closed state. When the user pushes the slide cover 2, the pushing force can release the engagement between the locking protrusion 52 and the locking groove 51, so that the slide cover 2 moves under the elastic force of the elastic member 43.

Illustratively, the locking protrusion 52 is a hemispherical protrusion, and the locking recess 51 is a matching hemispherical recess, which facilitates the user to release the snap-fit connection between the locking protrusion 52 and the locking recess 51.

Fig. 10 is a structural schematic view of a closed state of the shield, fig. 11 is a structural schematic view of an open state of the shield, and with reference to fig. 10 and fig. 11, optionally, another driving assembly 4 is further provided, the driving assembly 4 includes a first magnetic member 44 and a second magnetic member 45, and the first magnetic member 44 is located on the positioning and enclosing plate 12 and connected to the positioning and enclosing plate 12. The second magnetic member 45 is located on the sliding cover 2 and connected to the sliding cover 2, when the protective cover is in a closed state, the first magnetic member 44 is located on one side of the second magnetic member 45 in the moving direction, and the magnetism of the first magnetic member 44 and the magnetism of the second magnetic member 45 repel each other, when the protective cover is in an open state, the first magnetic member 44 is located on the other side of the second magnetic member 45 in the moving direction, and the magnetism of the first magnetic member 44 and the magnetism of the second magnetic member 45 repel each other.

In the above implementation manner, when the shield is in the closed state, the first magnetic member 44 is located on one side of the second magnetic member 45, and due to the mutual repulsion of the magnetism of the first magnetic member 44 and the second magnetic member 45, the first magnetic member 44 can be prevented from moving toward the second magnetic member 45 under the action of the repulsion force, so that the shield is kept in the closed state. After the user operates the sliding cover 2 to move to overcome the repulsive force between the first magnetic member 44 and the second magnetic member 45, so that the first magnetic member 44 moves to the other side of the second magnetic member 45, the protective cover is switched to the open state, and because the magnetism of the first magnetic member 44 and the magnetism of the second magnetic member 45 are still mutually exclusive at this time, the first magnetic member 44 and the second magnetic member 45 can continuously move back to back under the action of the repulsive force until the protective cover is completely opened.

In addition, when the driving assembly 4 includes the first magnetic member 44 and the second magnetic member 45, the shield can be maintained in the closed state by using the characteristic that the magnetism of the first magnetic member 44 and the second magnetic member 45 is repelled, so that the locking assembly 5 can be omitted in this case, and the production cost and the process of the shield can be reduced.

Illustratively, the first magnetic member 44 is located on the outer side surface of the positioning surrounding plate 12, and the second magnetic member 45 is located on the inner side surface of the moving surrounding plate 22, so that the repulsive force between the first magnetic member 44 and the second magnetic member 45 is stronger.
