Description

Technical Field

[0001] The present invention relates to the technical field of socket safety protection, and in particular to a socket protection cover and a socket protection device. Background Art

[0002] Sockets are common objects in life and are an indispensable part of every room. However, the sockets on the sockets are often exposed, which is very dangerous for children who have no safety awareness or are playful. Electric shock may occur when they touch the sockets.

[0003] In order to improve the safety of socket use, some socket protection covers have appeared on the market, such as the socket protection cover disclosed in Chinese Patent Publication No. CN201520845205.X, which includes a cover body made of insulating material and a plug pin. A rotatable handle is provided on the upper side of the cover body; the rotatable handle has a rotating shaft connected to the cover body; the cover body is provided with a handle groove, and when the rotatable handle is rotated into the handle groove, the surface of the cover body and the rotatable handle at the contact point are flush;

[0004] However, this patent still has some shortcomings: although the socket protection cover can be inserted into the socket to prevent children from directly touching the socket, since the handle is exposed, children are likely to directly pull up the handle and remove the protection cover, so there is a certain safety hazard. Summary of the Invention

[0005] The purpose of this technical solution is to provide a socket protection cover and a socket protection device, by moving the cover plate forward on the base so that the locking part is placed above the handle, thereby limiting the handle from rotating out of the receiving groove, improving the problem that the handle is easily extended from the base, making the socket protection cover unsafe to use.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A socket protection cover, comprising:

[0008] A base having a plurality of pins at its lower end and a receiving slot;

[0009] a handle rotatably connected to the upper end of the base, and the handle can be rotatably placed in the receiving groove;

[0010] a cover plate slidably disposed on the upper end of the base, and having a locking portion at the front end of the cover plate;

[0011] When the handle is rotated and placed in the receiving groove, the cover plate is pushed forward on the base, so that the locking portion is placed above the handle, thereby limiting the handle from rotating out of the receiving groove.

[0012] Preferably, a sliding groove is provided on the base, and a sliding block is provided at the lower end of the cover plate. The sliding block is inserted into the sliding groove, and the sliding block can slide along the side wall of the sliding groove.

[0013] Preferably, an elastic member is provided in the sliding groove;

[0014] When the cover is mounted on the base, both ends of the elastic member are movably connected to the sliding groove and the sliding block, respectively, so as to make the cover tend to move toward the front end of the base.

[0015] Preferably, the elastic part is integrally formed on the rear wall of the sliding groove; the elastic part has a connecting part, a deformation part and an abutment part, the rear end of the connecting part is connected to the rear wall of the sliding groove, the two ends of the deformation part are respectively connected to the connecting part and the abutment part, the deformation part is an arc-shaped strip, and the front end of the abutment part has an abutment plane.

[0016] Preferably, the sliding block has two sliding parts with an escape space between the two sliding parts, the lower end of the cover plate has an abutment protrusion, the abutment protrusion is located in the escape space, and the abutment protrusion movably abuts against the front end of the elastic member.

[0017] Preferably, the lower end of the sliding portion has an anti-slip portion, and the bottom of the sliding groove has an opening;

[0018] When the sliding portion is inserted into the sliding groove, the anti-slip portion extends out of the sliding groove from the opening and movably abuts against the lower edge of the opening;

[0019] The side wall of the sliding groove is provided with a first guide surface, and the side end of the anti-slip portion is provided with a second guide surface;

[0020] The second guide surface slides on the first guide surface to guide the sliding portion to be inserted into the sliding groove.

[0021] Preferably, a fixing portion protrudes from the front side wall of the sliding slot, and the lower end of the fixing portion is connected to the pin;

[0022] When the sliding block moves forward in the sliding groove, the fixing portion is inserted into the avoidance space.

[0023] Preferably, the handle is provided with a guide surface three;

[0024] When the handle is rotated and placed in the receiving groove, the guide surface three slides and abuts against the front end of the locking portion, so that the cover plate overcomes the action force of the elastic member and moves backward on the base.

[0025] Preferably, the receiving groove is provided with an escape opening, the escape opening is provided with a spring piece, and the spring piece movably extends into the receiving groove;

[0026] When the handle is rotated and placed in the receiving slot, the elastic sheet movably contacts the handle, so as to make the handle tend to move away from the receiving slot.

[0027] Preferably, the handle is provided with an avoidance groove, and the locking portion is slidably placed in the avoidance groove;

[0032] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0033] 1. The handle designed in this technical solution can be restricted in the receiving groove by the locking part of the cover plate, ensuring the stability of the handle when it is folded, preventing the handle from rotating out of the receiving groove due to children playing or gravity, and preventing the socket protective cover from being accidentally removed from the socket by children, thereby ensuring the safe and stable use of the socket protective cover.

[0034] 2. The base designed in this technical solution is provided with an elastic member, which drives the cover plate to move forward on the base, thereby ensuring that the locking portion of the cover plate can be located above the handle, thereby limiting the handle from rotating out of the receiving slot, ensuring that the handle will not be easily rotated open, and improving the safety of the socket protective cover.

[0035] 3. The handle designed in this technical solution is provided with a guide surface three, which is used to slide at the front end of the locking part. When in use, the user does not need to push the cover plate to move backward, but only needs to rotate the handle. The handle moves the cover plate backward under the action of the guide surface three. When the handle is placed in the accommodating groove, the elastic part automatically moves the cover plate forward, ensuring that the locking part can limit the rotation of the handle, which is simple and convenient to use.

[0036] 4. The storage box designed in this technical solution can be used to store several socket protection covers. When the socket protection covers are removed from the socket and not in use, the storage box can store the socket protection covers to prevent them from being placed randomly or lost. The storage box can be hung through the fixing holes to prevent children from taking them and playing with them. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The specific implementation of this technical solution is further described in detail below with reference to the accompanying drawings. Figures 1-11 .

[0050] Example 1, see Figures 1-10 :

[0051] A socket protection cover, comprising:

[0052] The base 1 has a plurality of pins 2 at its lower end and a receiving slot 3 at the front side of the upper end of the base 1. The base 1 is made of insulating material;

[0053] The handle 4 is rotatably connected to the upper end of the base 1 and can be rotatably placed in the receiving groove 3. When the handle 4 is completely placed in the receiving groove 3, the upper end surface of the base 1 is flush with the side end surface of the handle 4. Both ends of the handle 4 are hinged to the hinge grooves on the side walls of the receiving groove 3 through hinge shafts.

[0054] a cover plate 5 slidably disposed on the upper end of the base 1 , and having a locking portion 6 at the front end of the cover plate 5 ;

[0055] When the handle 4 is rotated and placed in the receiving groove 3, the cover plate 5 is pushed forward on the base 1, so that the locking portion 6 is placed above the handle 4, that is, the locking portion 6 extends into the notch of the receiving groove 3 and is located on the rotation trajectory of the handle 4, thereby limiting the handle 4 from rotating out of the receiving groove 3; when the locking portion 6 is placed above the handle 4, the locking portion 6 can abut and limit the rotation of the handle 4. When the handle 4 needs to be rotated out of the receiving groove 3, the cover plate 5 needs to be moved backward on the base 1 so that the locking portion 6 leaves the top of the handle 4.

[0056] A sliding groove 7 is provided on the base 1, and the sliding groove 7 is located on the rear side of the accommodating groove 3. A sliding block 8 is provided at the lower end of the cover 5, and the sliding block 8 is inserted into the sliding groove 7. The sliding block 8 can slide along the side wall of the sliding groove 7, thereby realizing the front and rear sliding of the cover 5 on the base 1. The front and rear side walls of the sliding groove 7 are used to limit the sliding range of the sliding block 8.

[0057] An elastic member 9 is provided in the sliding groove 7, and the elastic member 9 can be a spring, a tension spring or a rubber band;

[0058] When the elastic member 9 is a spring, and when the cover plate 5 is mounted on the base 1, the two ends of the elastic member 9 respectively abut against the rear wall of the sliding groove 7 and the rear end of the sliding block 8, so as to make the cover plate 5 have a tendency to move toward the front end of the base 1, thereby ensuring that the cover plate 5 moves forward so that the locking portion 6 extends into the notch of the receiving groove 3 and is located on the rotation trajectory of the handle 4, thereby ensuring that the locking portion 6 can prevent the handle 4 from rotating out of the receiving groove 3;

[0059] When the elastic member 9 is a tension spring or a rubber band, and when the cover 5 is installed on the base 1, the two ends of the elastic member 9 are respectively connected to the front wall of the sliding groove 7 and the front end of the sliding block 8, so that the cover 5 still has a tendency to move toward the front end of the base 1, thereby ensuring that the locking portion 6 can limit the handle 4 from rotating out of the accommodating groove 3.

[0060] In order to facilitate the installation of the cover plate 5 and the base 1 and reduce the number of parts, the elastic member 9 of this design is integrally formed on the base 1;

[0061] An elastic member 9 is integrally formed on the rear wall of the sliding groove 7; the elastic member 9 has a connecting portion 19, a deforming portion 20 and an abutting portion 21. The rear end of the connecting portion 19 is connected to the rear wall of the sliding groove 7, and the two ends of the deforming portion 20 are respectively connected to the connecting portion 19 and the abutting portion 21. The deforming portion 20 is an arc-shaped strip, and the front end of the abutting portion 21 has an abutting plane 22. The abutting plane 22 is used to ensure the abutting area with the rear end of the sliding block 8, thereby ensuring the stability of the connection.

[0062] The sliding block 8 of this design has two sliding parts 10, which are formed at the lower end of the cover plate 5, and there is an avoidance space 11 between the two sliding parts 10. The lower end of the cover plate 5 has a contact protrusion 12, which is located in the avoidance space 11. The contact protrusion 12 movably contacts the front end of the elastic member 9.

[0063] The lower end of the sliding portion 10 has an anti-slip portion 13, and the bottom of the sliding groove 7 has an opening 14;

[0064] When the sliding portion 10 is inserted into the sliding groove 7, the anti-slip portion 13 extends out of the sliding groove 7 from the opening 14 and movably abuts against the lower edge of the opening 14, preventing the sliding portion 10 from being separated from the sliding groove 7, thereby ensuring the stability of the connection between the cover plate 5 and the base 1; the side wall of the sliding portion 10 slides and abuts against the side of the sliding groove 7;

[0065] The side wall of the slot of the sliding slot 7 is provided with a guide surface 15, and the side end of the anti-slip portion 13 is provided with a guide surface 2 16;

[0066] During the process of inserting the sliding block 8 into the sliding groove 7, the guide surface 2 16 slides on the guide surface 15 to guide the sliding part 10 to be inserted into the sliding groove 7. At the same time, the avoidance space 11 can make the two sliding parts 10 close to each other, thereby facilitating the insertion of the sliding part 10 into the sliding groove 7.

[0067] On the base 1 with three pins 2, a fixing portion 23 protrudes from the front side wall of the sliding groove 7, and the lower end of the fixing portion 23 is connected to the pin 2; when the sliding block 8 moves forward in the sliding groove 7, the fixing portion 23 is inserted into the avoidance space 11, ensuring the forward movement distance of the sliding block 8 in the sliding groove 7, thereby ensuring that the locking portion 6 extends into the notch of the accommodating groove 3 and is located on the rotation trajectory of the handle 4.

[0068] The handle 4 is provided with a guide surface 3 28;

[0069] When the handle 4 is rotated and placed in the receiving groove 3, the guide surface 3 28 slides against the front end of the locking portion 6, so that the cover plate 5 overcomes the force of the elastic member 9 and moves backward on the base 1;

[0070] The design of the guide surface three 28 makes it unnecessary for the user to push the cover plate 5 backward and then rotate the handle 4 when rotating the handle 4 to place it in the receiving groove 3. The user only needs to rotate the handle 4 toward the receiving groove 3 so that the front end of the locking portion 6 is movably abutted against the guide surface three 28. Under the action of the guide surface three 28, the cover plate 5 can overcome the force of the elastic member 9 and move backward on the base 1, so that the locking portion 6 leaves the rotation trajectory of the handle 4, thereby allowing the handle 4 to smoothly enter the receiving groove 3. At the same time, after the handle 4 smoothly enters the receiving groove 3, the locking portion 6 can automatically rebound and move into the receiving groove 3 under the force of the elastic member 9, thereby limiting the handle 4 from rotating out of the receiving groove 3, reducing the operating steps, and being simple and convenient to use, saving trouble and effort.

[0071] The handle 4 is provided with an escape groove 17, and the locking portion 6 is slidably placed in the escape groove 17;

[0072] The receiving slot 3 is provided with a groove 18 , which is located at the front edge of the base 1 . The groove 18 is convenient for inserting fingers or nails, thereby facilitating the handle 4 to be rotated and opened.

[0073] A socket protection device, comprising:

[0074] A storage box 24 and at least one of the socket protection covers;

[0075] The upper end of the storage box 24 has a hanging portion 25 , and the hanging portion 25 has a hanging hole 26 . The storage box 24 has a plurality of fixing holes 27 for inserting the pins 2 .

[0076] The pins 2 of the socket protective cover can be inserted into the fixing holes 27, thereby realizing a fixed connection between the socket protective cover and the storage box 24; the storage box 24 allows the socket protective covers to be stored in an orderly manner, preventing unused socket protective covers from being thrown around randomly, and at the same time, the hanging holes 26 allow the storage box 24 to be hung on a wall or cabinet, which can prevent children from touching it and thus avoid the problem of losing or damaging it.

[0077] Example 2, see Figure 11 :

[0078] The design of this embodiment is basically the same as that of embodiment 1, except that:

[0079] An escape opening 29 is provided in the receiving groove 3, and a spring piece 30 is provided in the escape opening 29. The spring piece 30 is movable and extends into the receiving groove 3. One end of the spring piece 30 is integrally formed at the edge of the escape opening 29, and the other end of the spring piece 30 extends from the escape opening 29 and extends into the receiving groove 3.

[0080] When the handle 4 is rotated and placed in the accommodating groove 3, the spring piece 30 is elastically deformed and moves into the avoidance opening 29. At the same time, the spring piece 30 movably abuts the handle 4, so that the handle 4 has a tendency to move away from the accommodating groove 3; when the cover plate 5 moves backward on the base 1, so that the locking portion 6 leaves the rotation trajectory of the handle 4, the spring piece 30 elastically deforms and extends out of the avoidance opening 29 again and extends into the accommodating groove 3, so that the spring piece 30 bounces up the handle 4, making it convenient for the user to rotate the handle 4 out of the accommodating groove 3, which is simple and convenient to use.

[0081] The side wall of the handle 4 has a contact plane, which is in movably contact with the elastic sheet 30 , and the edge of the contact plane is connected to the edge of the guide surface 3 28 .
