All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic structural diagram of a hanging hole of a socket provided in an embodiment of the present application, and in order to more clearly show the hanging hole structure, a part of a socket body in fig. 1 has been cut away. Referring to fig. 1, the socket includes a socket body 1 and a moving member 2, the socket body 1 having a housing 11. The housing 11 has an opening 111, and the moving member 2 is retained in the opening 111. The inner wall of the opening 111 has a first sliding portion 112, the moving member 2 has a second sliding portion 22, and the first sliding portion 112 and the second sliding portion 22 are slidably engaged. The exposed surface 201 of the moving element 2 has a hanging hole 21, and the exposed surface 201 is exposed from the opening 111 in the thickness direction of the moving element 2.

The socket provided by the application, the moving member 2 provided with the hanging hole 21 is limited in the opening 111 on the housing 11, the moving member 2 is provided with the second sliding portion 22, and the moving member 2 can slide in the opening 111 through the sliding fit between the second sliding portion 22 and the first sliding portion 112 on the inner wall of the opening 111. After the screw is inserted into the hanging hole 21, the moving member 2 can change its position relative to the socket body 1 by sliding in the opening 111, so that the socket body 1 can adjust the position according to the use scene without re-fixing the screw position.

In a particular embodiment, as shown in FIG. 1, the housing 11 may comprise two parts, an upper housing 1101 and a lower housing 1102, the upper housing 1101 and the lower housing 1102 being detachably snap-fit together. The upper housing 1101 may have a jack through which a user may draw electricity. The opening 111 may be located on the lower case 1102, and may be further located on the bottom surface of the lower case 1102. When the above-described socket is hung on a wall, the bottom surface of the lower housing 1102 may face or be attached to the wall, and the upper housing 1101 is exposed to the outside of the wall, so that a user can use the jack conveniently.

Two opposite side walls of the opening 111 along the length direction of the opening are respectively abutted against two opposite sides of the moving member 2 along the width direction of the opening, so that the moving member 2 is limited in the opening 111. Also, the longitudinal direction of the opening 111 may be parallel to the longitudinal direction of the housing 11. Specifically, the opening 111 may be opened at one side edge of the housing 11 in the length direction, and one side of the opening 111 in the length direction may be flush with one side edge of the housing 11 in the length direction. That is, one inner wall of the opening 111 in the length direction is at least a part of one side wall of the housing 11 in the thickness direction thereof.

The first sliding portion 112 may be located at one side of the opening 111 in a length direction thereof, and the second sliding portion 22 may be located at one side of the moving member 2 in a width direction thereof, so as to maximally secure a sliding distance of the moving member 2. The sliding distance of the moving member 2 may be determined by the length of the opening 111. The length of the opening 111 may be smaller than the length of the housing 11 to prevent the moving member 2 from slipping out of the opening 111.

The exposed surface 201 of the moving member 2 is exposed from the opening 111, and in order to ensure the beauty of the socket product, after the moving member 2 is assembled into the opening 111, the exposed surface 201 can be flush with the surrounding housing 11.

The first sliding portion 112 and the second sliding portion 22 may be any one of a slide rail and a slide groove, and the shapes of the first sliding portion 112 and the second sliding portion 22 are adapted. Alternatively, as shown in fig. 2, the first sliding portion 112 may be a sliding rail, and the second sliding portion 22 may be a sliding chute. The slide rail may be located on an inner wall of the opening 111 on a side close to the edge of the housing 11. The moving member 2 may further have a protruding portion 23, the protruding portion 23 is connected to a bottom surface 202 of the moving member 2, the sliding groove is located between the protruding portion 23 and the bottom surface 202, and the bottom surface 202 is opposite to the exposed surface 201.

In a particular embodiment, as shown in fig. 2 and 8, the extension 23 may include a vertical section and a horizontal section connected to each other, wherein the vertical section is connected to the bottom surface 202, and the vertical section 22 is perpendicular to the bottom surface 202. The horizontal segment is located at the end of the vertical segment far from the bottom surface 202, the horizontal segment is perpendicular to the vertical segment, and the end of the horizontal segment far from the vertical segment can point to the end of the moving member 2 close to the side of the edge of the shell 11, so that a sliding groove can be formed between the protruding part 23 and the bottom surface 202. Meanwhile, the design of the extension part 23 also facilitates the demoulding of the moving part 2 during the integral forming.

The chute shown in fig. 2 is formed in a square shape in cross section. In other embodiments, the cross-sectional shape of the sliding groove may also be a triangle, and from the end of the moving member 2 to the inner side of the moving member 2 along the length direction thereof, the width of the sliding groove gradually increases to prevent the sliding rail from coming out of the sliding groove. The shape of the sliding rail is matched with that of the sliding groove.

The first sliding portion 112 (i.e., a slide rail) may be located on one side wall of the housing 11 in the thickness direction thereof, and an upper surface (a surface close to the side of the exposed surface 201) of the first sliding portion 112 may be flush with an upper surface (a surface close to the side of the exposed surface 201) of the side wall of the housing 11, so that the bottom surface 202 of the moving member 2 may be lapped on the upper surface of the first sliding portion 112, and an end portion of the bottom surface 202 close to the side of the edge of the housing 11 may be flush with an end portion of the exposed surface 201 close to the side of the edge of the housing 11.

In other embodiments, the first sliding portion 112 may also be spaced from the upper surface of the sidewall of the housing 11, so that the first sliding portion 112 is located inside the sidewall of the housing 11. A step may be formed between the bottom surface 202 and the exposed surface 201 of the moving member 2 in the thickness direction of the moving member 2 to fit the side wall of the housing 11 and the shape of the first sliding portion 112.

In the actual assembly process, the moving member 2 may be assembled to the first sliding portion 112 with an angle from the outside to the inside. For example, one end of the moving member 2 near the edge of the housing 11 may be fitted to the first sliding portion 112 obliquely at an angle of 45 degrees to the opening 111. The other end of the moving member 2 is gradually laid flat against the other side wall of the opening 111.

Alternatively, as shown in fig. 3, the moving member 2 may further have a third sliding portion 241, and the third sliding portion 241 and the second sliding portion 22 may be located at opposite sides of the moving member 2, respectively. In the specific embodiment, the second sliding portion 22 is located on the side of the moving member 2 close to the edge of the housing 11, and the third sliding portion 241 is located on the side of the moving member 2 away from the edge of the housing 11. In other embodiments, the positions of the second sliding portion 22 and the third sliding portion 241 may be switched, for example, the third sliding portion 241 is located on the side of the moving member 2 close to the edge of the housing 11, and the second sliding portion 22 is located on the side of the moving member 2 far from the edge of the housing 11.

Correspondingly, the socket may further include a positioning member 3, the positioning member 3 may be fixed to the inside of the housing 11, and the positioning member 3 may have a fourth sliding portion 32, and the fourth sliding portion 32 and the third sliding portion 241 are slidably fitted.

In the embodiment of the present application, the third sliding portion 241 and the fourth sliding portion 32 may be any one of a slide rail and a slide groove. For example, as shown in fig. 3, the third sliding portion 241 may be a sliding slot, and the fourth sliding portion 32 may be a sliding rail. All be provided with the sliding fit structure through the relative both sides along its length direction at moving member 2, can guarantee the gliding stability of moving member 2 in opening 111, avoid moving member 2 to take place the skew at the slip in-process.

Alternatively, as shown in fig. 3, the abutment surface between the third sliding portion 241 and the fourth sliding portion 32 may be a curved surface. In a specific embodiment, in the third sliding portion 241 and the fourth sliding portion 32, the radius of the arc surface of the slide rail may be greater than the radius of the arc surface of the slide groove, so that the slide rail and the slide groove are in interference fit, and the slide rail and the side wall of the slide groove are in line contact, thereby reducing the friction area.

In other embodiments, in the third sliding portion 241 and the fourth sliding portion 32, the width of the sliding groove may be slightly larger than that of the sliding rail, so that the sliding rail may be in line contact with the bottom surface of the sliding groove, and the friction area is reduced. Moreover, a certain extrusion force can exist between the third sliding portion 241 and the fourth sliding portion 32 along the sliding direction of the moving member 2 (i.e. the third sliding portion 241 and the fourth sliding portion 32 are in a slight interference fit state), so that a certain friction force can be generated in the sliding process of the moving member 2, and the moving member 2 is prevented from being loosened and displaced without being subjected to an external force.

Alternatively, as shown in fig. 3, in order to avoid the moving member 2 from being detached from the opening 111, the moving member 2 may further have a bridging portion 24, and the bridging portion 24 may be located on a side of the moving member 2 away from the edge of the housing 11. The third sliding portion 241 may be located on the overlapping portion 24, and a side of the overlapping portion 24 away from the third sliding portion 241 may overlap on an inner side of the case 11.

The overlapping portion 24 may be connected to the bottom surface 202 of the moving member 2, and two opposite sides along the thickness direction of the moving member 2 may respectively abut against the inner side surface of the housing 11 and the fourth sliding portion 32, so that the overlapping portion 24 may be clamped between the inner side surface of the housing 11 and the fourth sliding portion 32 to prevent one end of the moving member 2 away from the edge of the housing 11 from being separated from the opening 111.

In the actual assembly process, the moving member 2 can be assembled from the inside of the housing 11. One end of the moving member 2 near the edge of the housing 11 is fitted to the first sliding portion 112 obliquely at an angle of 45 degrees to the opening 111. Then, the overlapping portion 24 at the end of the moving member 2 remote from the edge of the housing 11 is overlapped on the inner side surface of the housing 11. The positioning member 3 is then fitted to the third sliding portion 241 from the top down inside the housing 11 to press the moving member 2.

Alternatively, as shown in fig. 4, in order to detachably fix the positioning member 3 to the inside of the housing 11, the inside of the housing 11 may have a fixing portion 113, and the fixing portion 113 may have a first fastening portion 1131 thereon. The positioning member 3 may further have a cover plate 31 and a second locking portion 33, the second locking portion 33 and the fourth sliding portion 32 may be located on a side of the cover plate 31 facing the opening 111, and the second locking portion 33 and the first locking portion 1131 may be locked to each other.

In a specific embodiment, the inner side of the housing 11 may have two fixing portions 113, and the two fixing portions 113 may be oppositely disposed along the length direction of the opening 111. And one end of the fixing portion 113 may be connected to a sidewall of the case 11 in the thickness direction, and the length of the fixing portion 113 may not be smaller than the width of the opening 111. An end of the fixing portion 113 distant from the edge of the case 11 may have a corner portion such that each fixing portion 113 may have an L-shape. The corner portions between the two fixing portions 113 face oppositely.

As shown in fig. 5, the positioning member 3 may further have a support portion 34, and the support portion 34 may be located at an end of the cover plate 31 away from the edge of the housing 11. When the positioning member 3 is fitted to the fixing portions 113, the supporting portion 34 may be located between the two fixing portions 113, and the shapes of the cover plate 31 and the supporting portion 34 are adapted to the shapes of the fixing portions 113, so that an accommodation space may be formed between the positioning member 3, the fixing portions 113, and the side walls of the housing 11 in the thickness direction. At least a part of the moving member 2 may be located in the accommodation space, thereby preventing the moving member 2 from interfering with other parts, such as the socket, etc., in the socket body 1.

Further, in order to improve the stability of the abutting between the positioning member 3 and the fixing portion 113, the fixing portion 113 may have a defect 1132 thereon, and correspondingly, the cover plate 31 may have a protrusion 35 on a side facing the opening 111, where the shape of the protrusion 35 is matched with that of the defect 1132. As shown in fig. 4, for positioning convenience, the defective portion 1132 may be located on a side of the fixing portion 113 near the edge of the housing 11. By providing the support portion 34 and the projection portion 35 on the cover plate 31, positioning and abutment between the positioning member 3 and the fixing portion 113 can be easily achieved. In other embodiments, the fixing portion 113 may have a protrusion thereon, and correspondingly, the cover plate 31 may have a recess with a matching shape thereon.

The support portion 34 and the fourth sliding portion 32 may each extend in the length direction of the cover plate 31, and the support portion 34 and the fourth sliding portion 32 may be arranged side by side in the width direction of the cover plate 31, and the fourth sliding portion 32 may be close to the inner side of the cover plate 31 (i.e., close to the edge of the housing 11) with respect to the support portion 34.

The second locking portion 33 may be located at one side of the cover plate 31 in the width direction, and the second locking portion 33 extends in the width direction of the cover plate 31. The second locking portion 33 can be locked from the side of the fixing portion 113 away from the opening 111, or the second locking portion 33 can be locked from the side of the fixing portion 113 close to the opening 111.

The two opposite sides of the moving element body along the thickness direction can be respectively an exposed surface 201 and a bottom surface 202. The guide groove 26 may be located on the side of the exposed surface 201, and the depth of the guide groove 26 may be smaller than the thickness of the moving member body 1, and the bottom surface of the guide groove 26 may be connected to the positioning notch 25 and the hanging hole 21. Also, the width of the guide groove 26 may be the same as or slightly less than the maximum width of the hanging hole 21. When the user aligns the positioning notch 25 with the screw, the screw can be slid into the hanging hole 21 along the guide groove 26, and thus the guide groove 26 can guide the screw.

Alternatively, as shown in fig. 8, the hanging hole 21 in the embodiment of the present application may be a gourd-shaped hanging hole, and in other embodiments, the hanging hole 21 may also be a cross-shaped hanging hole. Specifically, the hanging hole 21 may include a circular hole 211 and at least one bar hole 212 which are communicated with each other. The plurality of bar-shaped holes 212 are uniformly distributed along the circumferential direction of the circular hole 211.
