[0039] With the popularization of electronic devices and household appliances, the use of sockets is becoming more and more extensive. However, the safety, dust-proof and waterproof performance of sockets have become the focus of user attention. The traditional socket design has some defects. For example, the socket is directly exposed, which is easy to accumulate dust and water, affecting the service life and safety; the dust-proof cover needs to be manually opened, which affects the use experience. Therefore, it is necessary to set a sliding cover structure for the socket to ensure the safety, dust-proof and waterproof performance of the socket. The traditional socket sliding cover mechanism has high requirements for the contact accuracy of the sliding guide rail. If the contact surface between the sliding cover and the socket is too loose, it is easy to cause the movement track of the sliding cover not to be a straight line during the sliding process, and even the sliding cover may fall off. If the contact surface between the sliding cover and the socket is too tight, it will make the sliding difficult, affect the use experience, and at the same time cause wear of the sliding cover and reduce the product life.

[0040] The utility model provides a sliding cover device. Please refer to Figures 1 to 14 , the sliding cover device includes: a base 1 and a sliding cover 2, and the sliding cover 2 is slidably connected to the base 1; a socket panel 3 is provided on the base 1, a chute 1a is opened on the side wall of the base 1, and a slide rail 11 is provided in the chute 1a along the sliding direction of the sliding cover 2, and both ends of the slide rail 11 have first limiting portions 11a; the inner side of the sliding cover 2 has a cantilever 21, the cantilever 21 is slidably connected to the chute 1a, and both ends of the cantilever 21 have locking members 211, and the locking members 211 are adapted to the first limiting portions 11a to realize the limit locking of the sliding cover 2 and the base 1 when the sliding cover 2 slides to both ends of the slide rail 11.

[0041] In this embodiment, the sliding cover device includes a base 1 and a sliding cover 2. The base 1 has an outer panel 12 partially covered by the sliding cover 2 and base side walls located on both sides of the outer panel 12. At least one base side wall is provided with a chute 1a. Preferably, the base side walls on both sides are symmetrically provided with chutes 1a. A slide rail 11 is provided in the chute 1a along the sliding direction of the sliding cover 2. The slide rail 11 is the inner side surface of the chute 1a away from the outer panel 12. The slide rail 11 has a head and a tail. The sliding cover 2 can slide from the head of the slide rail 11 towards the tail, or can slide from the tail of the slide rail 11 towards the head. A socket panel 3 is provided on the base 1. The socket panel 3 is used to connect with an external electrical appliance plug. When the sliding cover 2 slides from the head of the slide rail 11 towards the tail, the socket panel 3 is exposed. When the sliding cover 2 slides from the tail of the slide rail 11 towards the head, the socket panel 3 is shielded. A cantilever 21 protrudes from the side wall of the sliding cover 2 facing the chute 1a. The cantilever 21 is correspondingly arranged with the chute 1a. The cantilever 21 is inserted into the chute 1a and is slidably connected with the slide rail 11. First limiting parts 11a are respectively provided at both ends of the slide rail 11 near the head and near the tail. The first limiting parts 11a can be set as protrusions, stoppers or depressions. Locking parts 211 are respectively provided at both ends of the cantilever 21. The locking parts 211 can be set as depressions, clamping blocks or protrusions that cooperate with the first limiting parts 11a. When the cantilever 21 moves along the slide rail 11 until the locking part 211 at one end of the cantilever 21 moves to the head or tail of the slide rail 11, the locking part 211 is engaged with the first limiting part 11a, ensuring that the locking part 211 will not easily disengage from the first limiting part 11a to cause sliding, and the sliding cover 2 cannot continue to move in this direction, restricting the moving range of the sliding cover 2. At this time, the sliding cover 2 is still connected to the slide rail 11 and is in a stable open or stable closed state. If you want to move the sliding cover 2 to the other end of the slide rail 11, a certain force needs to be applied to the sliding cover 2 to make the locking part 211 disengage from the first limiting part 11a, so that the sliding cover 2 can continue to move on the slide rail 11 until the sliding cover 2 slides to the other end of the slide rail 11.

[0042] An embodiment is proposed by the present utility model. Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 14 , the socket panel 3 has a socket boss 32. The base 1 is provided with a mounting opening 121. The socket boss 32 is inserted into the mounting opening 121. When the sliding cover 2 slides along the slide rail 11, the socket boss 32 is shielded or exposed.

[0043] Specifically, the side of the socket panel 3 facing the base 1 is the socket connection surface 31, and the socket boss 32 is arranged on the socket connection surface 31. The socket boss 32 is used for the plug of the electrical appliance to be inserted. Optionally, the socket boss 32 can be provided with socket connection holes of different models, such as two-hole type, three-hole type, five-hole type, etc., and can also be set as USB jacks, TYPE-C jacks, etc., to meet the usage requirements of different application scenarios. The side of the base 1 facing the socket panel 3 is the inner panel 13, and the side facing away from the socket panel 3 is the outer panel 12. An installation opening 121 extending from the outer panel 12 to the inner panel 13 is provided on the base 1, and the shape and size of the installation opening 121 are adapted to the socket boss 32. The socket boss 32 is inserted into the installation opening 121. The sliding cover 2 moves along the slide rail 11 towards the head direction of the slide rail 11 to cover the socket boss 32, and the sliding cover 2 moves along the slide rail 11 towards the tail direction of the slide rail 11 to expose the socket boss 32. After the socket panel 3 and the base 1 are installed, the socket boss 32 is flush with the outer panel 12 or slightly protrudes from the outer panel 12, which is convenient for the sliding opening of the sliding cover 2. Connection holes 311 are provided on the socket connection surface 31, and connection posts 131 are provided on the inner panel 13. The position, shape, and size of the connection posts 131 are adapted to the connection holes 311. The base 1 and the socket panel 3 are connected in a guiding manner through the connection posts 131 and the connection holes 311. The socket panel 3 also has a socket side wall 33, and a second clamping groove 331 is provided on the socket side wall 33. Second clamping protrusions 332 are symmetrically arranged in the second clamping groove 331. The side of the base 1 facing the socket side wall 33 is the inner wall 14 of the base. A first clamping protrusion 141 is correspondingly provided on the inner wall 14 of the base. The first clamping protrusion 141 is clamped into the second clamping groove 331 and cooperates with the second clamping protrusion 332 to realize the clamping and fixing of the base 1 and the socket panel 3. The base 1 is slidably connected with a sliding cover 2 that can cover the socket boss 32. When the socket is not in use, the sliding cover 2 slides to one end close to the socket panel 3, and the sliding cover 2 covers the socket boss 32 to prevent accidental touch or foreign objects from entering the socket. When the socket is in use, the sliding cover 2 is slid to expose the socket boss 32, which is convenient for the connection of the electrical appliance plug.

[0044] Further, please refer to Figure 2 With Figure 8 , a sealing groove 22a is provided on the side of the sliding cover 2 facing the base 1, and a sealing ring 4 is arranged in the sealing groove 22a. The sealing ring 4 is adapted to the socket boss 32 to realize the sealing protection of the socket boss.

[0045] Specifically, the side of the sliding cover 2 facing the base 1 is the inner sliding cover plate 22. The inner sliding cover plate 22 is provided with a sealing groove 22a and a plurality of reinforcing ribs. The inner sliding cover plate 22 and the reinforcing ribs form a plurality of grooves, which can reduce the overall weight of the sliding cover 2 and the material cost during the production process. At the same time, the reinforcing ribs strengthen the structural strength of the sliding cover 2. A sealing ring 4 is arranged in the sealing groove 22a. The sealing ring 4 can be made of an elastic material such as sponge, rubber, silica gel, etc., which is not limited here. The position and size of the sealing ring 4 are adapted to the socket boss 32. When the sliding cover 2 slides towards the head of the slide rail 11, the sliding cover 2 covers the socket panel 3, and the sealing ring 4 covers the socket boss 32, which can effectively prevent dust or other foreign objects from entering the socket panel 3 and realize the function of sealing and protecting the socket panel 3. Preferably, a guiding protrusion 221 is coaxially arranged in the sealing groove 22a. The sealing ring 4 has a coaxial guiding hole 4a, which is a hollow circular ring structure. The guiding hole 4a is adapted to the guiding protrusion 221. The sealing ring 4 is clamped in the space formed by the enclosure of the guiding protrusion 221 and the sealing groove 22a to prevent the sealing ring 4 from shaking and shifting during the movement of the sliding cover 2. Further, the sealing ring 4 can be fixed in the sealing groove 22a by an adhesive method to ensure the structural stability of the cooperation between the sealing ring 4 and the sealing groove 22a.

[0046] Further, please refer to Figure 8 With Figure 9 , the sliding cover 2 has a sliding cover side wall 2a. The cantilever 21 is arranged on the side of the sliding cover side wall 2a facing the chute 1a. The sliding cover side wall 2a is provided with a through hole 2b around the locking member 211. The locking member 211 extends outward along the direction away from the chute 1a.

[0047] Specifically, the side walls 2a of the sliding cover are symmetrically arranged on both sides of the sliding cover 2. A cantilever 21 is arranged on the side of the side wall 2a of the sliding cover facing the chute 1a. The cantilever 21 is snapped into the chute 1a, and the cantilever 21 is slidably connected to the chute 1a. Preferably, two chutes 1a are symmetrically arranged on the left and right side walls of the base 1, and the positions of the cantilever 21 and the chute 1a are correspondingly arranged. Two cantilevers 21 are symmetrically arranged on the side walls 2a of the two sides of the sliding cover 2 and are respectively matched with the two chutes 1a. The cantilevers 21 on both sides of the sliding cover 2 extend into the chutes 1a on both sides of the base 1, so that the sliding cover 2 will not break away from the base 1 during the sliding process, and the sliding of the sliding cover 2 along the direction of the slide rail 11 of the base 1 is restricted. Symmetrical arrangement on the left and right can make the sliding of the sliding cover 2 smoother. A through hole 2b is formed in the side wall 2a of the sliding cover around the locking member 211, and there is a gap between the outer wall of the locking member 211 and the hole wall of the through hole 2b. The locking member 211 extends outward along the direction away from the chute 1a, and the end surface of the locking member 211 away from the chute 1a is flush with the end surface of the side wall 2a of the sliding cover away from the chute 1a. When the locking member 211 slides on the slide rail 11, the through hole 2b provides a certain elastic deformation margin for the locking member 211. When the locking member 211 is squeezed, it will produce a certain amount of movement deformation in the up and down direction or left and right direction or front and back direction within the gap. So that the locking member 211 moves on the slide rail 11 and can produce movement deformation within the gap range when engaging with the first limiting portion 11a. It is beneficial to the sliding fit between the cantilever 21 and the slide rail 11, reduces the loss generated during the sliding process of the sliding cover 2 and the base 1, and improves the service life and product stability of the sliding cover device.

[0048] Further, please refer to Figure 3 , Figure 5 and Figure 13 , the middle part of the slide rail 11 has a second limiting portion 11b, and the locking member 211 is in interference fit with the chute 1a at the second limiting portion 11b.

[0049] Specifically, the second limiting portion 11b is a raised structure in the middle of the slide rail 11. When the locking member 211 at one end of the cantilever 21 slides past the second limiting portion 11b and contacts the raised portion, the locking member 211 is slightly in interference fit with the chute 1a, so that the locking member 211 has a certain stability at the second limiting portion 11b and will not shake. At this time, a certain thrust needs to be applied to the sliding cover 2 to make the locking member 211 slide out of the second limiting portion 11b and continue to move towards the head or tail of the slide rail 11.

[0050] Further, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , there is a smooth portion 113 between the first limiting portion 11a and the second limiting portion 11b; the length of the smooth portion 113 is adapted to the distance between the locking members 211 at both ends of the cantilever 21.

[0051] It can be understood that the slide rail 11 is composed of two first limiting parts 11a located at the head and the tail respectively, a second limiting part 11b located in the middle of the slide rail 11, and two smooth parts 113. There is a smooth part 113 between the first limiting part 11a and the second limiting part 11b at the head of the slide rail 11, and there is another smooth part 113 between the first limiting part 11a and the second limiting part 11b at the tail of the slide rail 11. The two first limiting parts 11a are symmetrically arranged according to the second limiting part 11b. The lengths of the two smooth parts 113 are both adapted to the distance between the locking parts 211 at both ends of the cantilever 21. The width of the chute 1a at the second limiting part 11b is smaller than the width of the chute 1a at the smooth part 113, and the locking part 211 can slide normally on the smooth part 113. When the locking part 211 at one end of the cantilever 21 close to the head of the slide rail 11 slides to the first limiting part 11a at the head of the slide rail 11 and engages with the first limiting part 11a, the locking part 211 at the other end of the cantilever 21 is in a slightly interference connection with the second limiting part 11b. At this time, the sliding cover 2 is in a stable closed state, covering the socket panel 3 and not easily sliding. When the socket panel 3 needs to be used, a thrust is applied to the sliding cover 2, so that the locking part 211 at one end of the cantilever 21 is separated from the first limiting part 11a and enters the smooth part 113 close to the first limiting part 11a, and the locking part 211 at the other end of the cantilever 21 is separated from the second limiting part 11b and enters the other smooth part 113. The cantilever 21 slides on the slide rail 11 through the locking parts 211 at both ends until the locking part 211 at the end of the cantilever 21 close to the tail of the slide rail 11 engages with the first limiting part 11a at the tail, and the locking part 211 at the other end of the cantilever 21 is in a slightly interference connection with the second limiting part 11b. At this time, the sliding cover 2 is in a stable open state, and the socket panel 3 is exposed and can be plugged and used with an external plug. Preferably, the smooth part 113 and the second limiting part 11b are in an arc transition, and the smooth part 113 and the first limiting part 11a are in an arc transition, so that the sliding of the locking part 211 on the slide rail 11 is smoother, facilitating the opening and closing of the sliding cover 2.

[0052] Further, please refer to Figure 4 , the first limiting part 11a has a first protrusion 112, a first recess 111 is provided on the side of the first protrusion 112 away from the smooth part 113, the transition surface between the first protrusion 112 and the first recess 111 is in an arc transition, and the first protrusion 112, the first recess 111 and the side wall of the chute 1a enclose a positioning groove 111a.

[0053] Specifically, a first concave portion 111 is provided on a side of the first convex portion 112 away from the smooth portion 113, and the first concave portion 111 is an arc-shaped concave portion. The transition surface between the first concave portion 111 and the first convex portion 112 is an arc transition, and the first convex portion 112 and the smooth portion 113 are arc transitions, which facilitates the engagement and disengagement of the locking member 211 at the first limiting portion 11a. The width of the sliding groove 1a at the first convex portion 112 is smaller than the width of the sliding groove 1a at the smooth portion 113, and the width of the sliding groove 1a at the first convex portion 112 is slightly smaller than the height of the cantilever 21 at the locking member 211. The width of the sliding groove 1a at the first concave portion 111 is adapted to the height of the cantilever 21 at the locking member 211. It can be understood that when the sliding cover 2 slides to the first limiting portion 11a, a certain pushing force needs to be applied to the sliding cover 2 to make the locking member 211 slide through the first convex portion 112 and snap into the positioning groove 111a. When the locking member 211 is located in the positioning groove 111a, it is limited by the first convex portion 112 and will not move along the sliding direction of the sliding cover 2. At this time, the sliding cover 2 is in a stable open or stable closed state, and the locking member 211 at one end of the cantilever 21 away from the first limiting portion 11a is slightly interference-connected with the second limiting portion 11b, and the locking members 211 at both ends of the cantilever 21 are in a stable state and not easy to slide. If you want to make the sliding cover 2 slide to the other end of the slide rail 11, a pushing force needs to be applied to the sliding cover 2 so that the locking member 211 at one end of the sliding cover 2 disengages from the positioning groove 111a, passes through the first convex portion 112 and enters the smooth portion 113, and the locking member 211 at the other end of the sliding cover 2 separates from the second limiting portion 11b and enters the smooth portion 113. The sliding cover 2 moves along the slide rail 11 until the locking member 211 at one end of the sliding cover 2 engages with the first limiting portion 11a at the other end of the slide rail 11.

[0054] Further, please refer to Figure 9 With Figure 11 , a locking member 211 is provided on the cantilever 21 corresponding to the positioning groove 111a, and the locking member 211 is a columnar protrusion.

[0055] It can be understood that the locking member 211 is a columnar protrusion, the first recess 111 is an arc-shaped concave structure, and the locking member 211 cooperates with the first recess 111 at both ends of the slide rail 11. There is a sliding portion between the two locking members 211 at both ends of the cantilever 21, and the locking member 211 and the sliding portion have a circular arc transition. The cantilever 21 is provided with a locking member 211 corresponding to the positioning groove 111a, and through holes 2b for providing elastic deformation allowance are opened around the locking member 211. The locking member 211 extends outward along the direction away from the chute 1a, and the end face of the locking member 211 away from the chute 1a is flush with the end face of the side wall 2a of the sliding cover away from the chute 1a. The part of the locking member 211 exceeding the through hole 2b is adapted to the positioning groove 111a. Preferably, the locking member 211 is a semi-cylindrical protrusion, and the shape of its outer wall cooperates with the first recess 111. The contact surface between the first recess 111 and the locking member 211 is less than the semi-cylindrical surface of the locking member 211, and the height of the first protrusion 112 does not exceed the semi-cylindrical radius of the locking member 211, which is convenient for the locking member 211 to be inserted and removed, and prevents the sliding cover 2 from being difficult to open and close. When the locking member 211 passes through the first protrusion 112, the locking member 211 is squeezed to generate movement deformation in the through hole 2b, which is convenient for the locking member 211 to pass through the first protrusion 112 and is conducive to the sliding cooperation between the locking member 211 and the positioning groove 111a.

[0056] Further, please refer to Figure 11 , one side of the locking member 211 facing the positioning groove 111 has a protruding portion 2111, and the protruding portion 2111 is an elastic structure that can be telescoped under an external force. The protruding portion 2111 is in interference connection with the base 1 in the positioning groove 111a.

[0057] It can be understood that one side of the locking member 211 facing the positioning groove 111a has a protruding portion 2111. When the locking member 211 is in limit connection with the first limit portion 11a, the protruding portion 2111 extends into the positioning groove 111a and is in interference connection with the positioning groove 111a, so that the locking member 211 has a slight interference and does not shake in the positioning groove 111a, ensuring stronger connection stability when the base 1 and the sliding cover 2 are in a stable closed state or a stable open state. Preferably, the protruding portion 2111 is an elastic structure. During the process of the sliding cover 2 sliding to the head or tail of the slide rail 11, the protruding portion 2111 is squeezed, so that the locking member 211 realizes elastic locking in the positioning groove 111a, avoiding rigid extrusion and wear, and improving the service life of the product.

[0058] Further, please refer to Figure 6 、 Figure 11 And Figure 13 , the chute 1a has a chute inclined surface 114, and the cross-sectional width of the opening of the chute 1a is greater than the cross-sectional width of the bottom of the chute 1a; one side of the cantilever 21 facing the chute inclined surface 114 has a cantilever inclined surface 212 adapted to the chute inclined surface 114.

[0059] Specifically, the cross-section of the chute 1a is trapezoidal, the width of the opening of the cross-section of the chute 1a is greater than the width of the bottom of the cross-section of the chute 1a, and the chute inclined surface 114 is the side surface in the chute 1a opposite to the slide rail 11. One side of the cantilever 21 facing the chute inclined surface 114 has a cantilever inclined surface 212 adapted to the chute inclined surface 114, and the cantilever inclined surface 212 is slidably connected to the chute inclined surface 114. The inclination of the cantilever inclined surface 212 is correspondingly set with the inclination of the chute inclined surface 114, which is convenient for guiding the cantilever 21 to extend into the chute 1a, making the assembly of the sliding cover 2 and the base 1 more convenient.

[0060] In the sliding cover device of the present utility model, when the socket panel 3 is not in use, the sliding cover 2 shields the socket panel 3, and the sealing ring 4 provided in the sliding cover 2 provides dust-proof and waterproof protection for the socket panel 3. One end locking member 211 of the cantilever 21 is located at the head position of the slide rail 11 and is engaged with the first limiting portion 11a, and the protruding portion 2111 is slightly interference-connected with the positioning groove 111a; the locking member 211 at the other end of the cantilever 21 is located at the second limiting portion 11b and is slightly interference-connected with the second limiting portion 11b. At this time, the sliding cover 2 is in a stable closed state and will not easily slide. When the socket panel 3 needs to be used, a certain pushing force needs to be applied to the sliding cover 2 to disengage the locking member 211 at one end of the cantilever 21 from the first limiting portion 11a and the locking member 211 at the other end from the second limiting portion 11b. The two locking members 211 at both ends of the cantilever 21 enter the smooth portion 113 and slide on the smooth portion 113. The sliding cover 2 moves along the track direction of the slide rail 11 from the head to the tail of the slide rail 11. Until the locking member 211 at one end of the cantilever 21 is engaged with the first limiting portion 11a at the tail of the slide rail 11, and the protruding portion 2111 is slightly interference-connected with the positioning groove 111a; the locking member 211 at the other end of the cantilever 21 is located at the second limiting portion 11b and is slightly interference-connected with the second limiting portion 11b. At this time, the sliding cover 2 is in a stable open state, and the socket panel 3 is exposed and can be plugged with an external plug for use. After use, the sliding cover 2 is restored to the stable closed state to prevent accidental touch or impurities from entering the socket.
