These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0053] The terminology used in the embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure. Unless otherwise defined, the technical or scientific terms used herein should be understood in their ordinary sense by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” “third,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “a” or “one,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “comprising,” “including,” and similar terms mean that the elements or objects preceding “comprising” or “including” encompass the elements or objects listed following “comprising” or “including” and their equivalents, and do not exclude other elements or objects. The terms “connected,” “linked,” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0054] This disclosure provides a lifting socket, such as... Figure 1 As shown, the lifting socket includes a receiving cylinder 1, a socket body 2, and a driving component 3. Figure 1 (Not shown in the image). The socket body 2 is inserted into the receiving cylinder 1, and the socket body 2 is rotatable relative to the receiving cylinder 1. The driving member 3 is located in the receiving cylinder 1 and is connected to both the receiving cylinder 1 and the socket body 2. The driving member 3 is used to drive the socket body 2 to extend out of the receiving cylinder 1.

[0055] The receiving tube 1 is used to store the socket body 2 and to fix it to external surfaces such as desktops, floors, and walls.

[0056] The socket body 2 is the main electrical component of the lift socket, including the housing and the power supply component located inside the housing. The power supply component includes the socket sleeve and the protective door, etc. The part of the housing corresponding to the socket sleeve has a socket hole, and the protective door blocks the socket hole.

[0057] The driving component 3 is connected to both the receiving cylinder 1 and the socket body 2, and is at least used to drive the socket body 2 out of the receiving cylinder 1. To prevent the driving component 3 from obstructing the rotation of the socket body 2, in some examples, the driving component 3 is rotatably connected to the socket body 2, and the socket body 2 is axially limited by the driving component 3. In this way, the driving component 3 can drive the socket body 2 normally without obstructing the rotation of the socket body 2.

[0058] This disclosure provides a retractable power strip. When the retractable power strip is needed, the user operates the drive unit 3 to extend the socket body 2 out of the receiving cylinder 1. Then, after rotating the socket body 2 to a suitable position, the plug of the appliance is inserted into the socket hole on the socket body 2. When the retractable power strip is not needed, the plug is unplugged, and the user manually presses down the socket body 2 to retract the receiving cylinder 1, or controls the drive unit 3 to retract the socket body 2 into the receiving cylinder 1. Therefore, the retractable power strip provided by this disclosure is very convenient to use.

[0059] It should be noted that, Figure 1 The baseline a shown is only to indicate that the socket body 2 can rotate when the housing cylinder 1 is stationary. In the actual product, the lifting socket does not have a baseline a.

[0060] The type of the driving component 3 is not limited in the embodiments disclosed herein. In some examples, the driving component 3 is used to both drive the socket body 2 to extend out of the receiving cylinder 1 and to drive the socket body 2 to retract into the receiving cylinder 1. For example, the driving component 3 is a driving component with bidirectional driving capability, such as an electric push rod.

[0061] In other examples, the drive element 3 is only used to drive the socket body 2 to extend out of the receiving cylinder 1, and the force for the socket body 2 to descend can be provided by the user. For example, the drive element 3 is a spring, such as a gas spring and a common compression spring.

[0062] In order for the socket body 2 to be stably retracted into the receiving cylinder 1, the socket body 2 can be locked with the receiving cylinder 1 in the retracted state, for example, as shown in the example. Figure 2 , Figure 6 and Figure 12 As shown, the lifting socket also includes a first fastener 4 and a second fastener 5. The first fastener 4 is located inside the receiving cylinder 1, and the second fastener 5 is connected to the socket body 2. The first fastener 4 is used to lock with the second fastener 5.

[0063] Furthermore, during the rotation of the socket body 2, the positions of the first fastener 4 and the second fastener 5 remain relative. This ensures that the first fastener 4 and the second fastener 5 will not become misaligned during the rotation of the socket body 2, allowing them to engage and lock in place regardless of the position to which the socket body 2 is rotated before lowering.

[0064] The following is an example illustrating how the positions of the first fastener 4 and the second fastener 5 remain relative during the rotation of the socket body 2:

[0065] (1) In some examples, such as Figure 2As shown, the socket body 2 is rotatably connected to the receiving cylinder 1. The first fastener 4 is fixedly connected to the receiving cylinder 1, and the second fastener 5 is fixedly connected to the socket body 2. At least a portion of the side of one of the first fastener 4 and the second fastener 5 is arc-shaped, and the central axis of the arc is collinear with the rotation axis of the socket body 2. Any portion of the arc-shaped side can be locked with the other fastener.

[0066] Since at least a portion of the side of one of the first fasteners 4 and the second fastener 5 is arc-shaped, and any part of the arc-shaped side can be locked with the other fastener, as long as the arc-shaped side is always opposite to the other fastener during the rotation of the socket body 2 relative to the receiving cylinder 1, it can be ensured that the first fastener 4 and the second fastener 5 can be locked after the socket body 2 is lowered.

[0067] This disclosure does not limit the angle corresponding to the arc-shaped side in the embodiments. In some examples, such as Figure 3 As shown, the side of one of the first fasteners 4 and the second fastener 5 is in the shape of a closed arc. That is, the angle corresponding to this arc is 360°, or it can be understood that one of the first fasteners 4 and the second fastener 5 is in the shape of a ring or a plate.

[0068] By setting the sidewall of the first fastener 4 or the second fastener 5 to be a closed ring, the positions of the first fastener 4 and the second fastener 5 can always remain corresponding during the relative rotation process. No matter how the relative positions of the first fastener 4 and the second fastener 5 change, the first fastener 4 and the second fastener 5 can cooperate to lock without misalignment.

[0069] In other examples, one of the fasteners, the first fastener 4 and the second fastener 5, has a side that is not closed and has an arc shape (or a partial arc shape). That is, the angle corresponding to this arc shape is less than 360°. In this case, a rotation limit structure is required to limit the rotation angle range of the socket body 2 and prevent the non-arc-shaped side from facing the other fastener.

[0070] This disclosure does not limit which of the first fastener 4 and the second fastener 5 has an arc-shaped side. In some examples, the first fastener 4 is a single-sided or double-sided locking fastener (e.g., Figure 4 As shown), at least a portion of the side of the second fastener 5 is arc-shaped.

[0071] The arc-shaped side portion can be either the outer side portion or the inner side portion; this disclosure does not limit this aspect.

[0072] In some examples, such as Figure 2 As shown, the outer side of the second fastener 5 is arc-shaped and is used to lock with the first fastener 4. The outer edge of the second fastener 5 protrudes outward relative to the socket body 2 (e.g., Figure 3(As shown). Accordingly, the first fastener 4 is located outside the second fastener 5 (as shown). Figure 2 (As shown).

[0073] In other examples, the inner side of the second fastener 5 may be used for locking, in which case the inner edge of the second fastener 5 protrudes inward relative to the socket body 2. Correspondingly, the first fastener 4 is located inside the second fastener 5.

[0074] This disclosure does not limit the number of single-sided or double-sided latches (such as the first fastener 4). In some examples, such as... Figure 2 As shown, there are multiple first fasteners 4, which can be evenly distributed along the circumference of the receiving cylinder 1. For example, as shown... Figure 5 As shown, there are four first fasteners, number 4.

[0075] (2) In some examples, such as Figure 6 and Figure 7 As shown, the receiving cylinder 1 includes an outer cylinder 11 and a rotating sleeve 12. The rotating sleeve 12 is located inside the outer cylinder 11, rotatably connected to the outer cylinder 11, and axially limited within the outer cylinder 11. A first fastener 4 is located inside the rotating sleeve 12 and fixedly connected to it. A second fastener 5 is fixedly connected to the socket body 2, with the first fastener 4 and the second fastener 5 facing each other. The socket body 2 is inserted into the rotating sleeve 12 and circumferentially limited within it. The socket body 2 can move up and down relative to the rotating sleeve 12, and both the socket body 2 and the rotating sleeve 12 can rotate together relative to the outer cylinder 11.

[0076] The technical solution provided in this embodiment of the present disclosure is to provide a rotating sleeve 12 that can rotate together with the socket body 2, and to connect the first fastener 4 to the rotating sleeve 12, so that the first fastener 4 and the second fastener 5 will rotate synchronously during the rotation of the socket body 2, so that no matter which position the socket body 2 rotates to, the positions of the first fastener 4 and the second fastener 5 can remain relative, and the first fastener 4 and the second fastener 5 will not be misaligned.

[0077] This disclosure does not limit the implementation method of axially limiting the rotating sleeve 12 in the outer cylinder 11. In some examples, such as Figure 8 As shown, the rotating sleeve 12 is axially limited in the outer cylinder 11 by the snap-lock plate 13. The outer cylinder 11 has a bearing plate 111 inside, and the snap-lock plate 13 is connected to the bearing plate 111, forming a limiting gap 130 between the snap-lock plate 13 and the bearing plate 111. The bottom of the rotating sleeve 12 has an opening 120, and the edge of the rotating sleeve 12 at the opening 120 is located in the limiting gap 130.

[0078] That is, the edge of the rotating sleeve 12 at the opening 120 is limited in the limiting gap 130, so that the rotating sleeve 12 cannot be removed from the outer cylinder 11.

[0079] In addition, since the rotating sleeve 12 needs to rotate relative to the outer cylinder 11, the size of the limiting gap 130 is larger than the size of the edge of the rotating sleeve 12 at the opening 120, so as to prevent the rotating sleeve 12 from getting stuck and unable to rotate.

[0080] Of course, in addition to the above methods, other methods can be used to limit the axial movement of the rotating sleeve 12 in the outer cylinder 11. For example, a baffle can be provided at the top of the outer cylinder 11 to prevent the rotating sleeve 12 from coming off the top of the outer cylinder 11.

[0081] The following is a more detailed illustrative description of the ring plate 13:

[0082] like Figure 9 As shown, the ring-shaped fastener 13 includes a flange portion 131, a connecting portion 132, and a plurality of snap-fit ​​portions 133. The flange portion 131 is located on the side of the support plate 111 facing the bottom of the outer cylinder 11. The connecting portion 132 passes through the support plate 111. The plurality of snap-fit ​​portions 133 are located on the side of the support plate 111 facing the top of the outer cylinder 11, and a limiting gap 130 is formed between the plurality of snap-fit ​​portions 133 and the support plate 111. The support plate 111 has a through hole through which the connecting portion 132 passes.

[0083] In some examples, there are four latches 133, which are evenly distributed circumferentially.

[0084] This disclosure does not limit the implementation method of the rotatable connection between the rotating sleeve 12 and the outer cylinder 11. In some examples, such as Figure 8 As shown, the rotating sleeve 12 has a first protruding ring 121 on the side facing the bottom of the outer cylinder 11, and the first protruding ring 121 is coaxial with the rotation axis of the rotating sleeve 12. The outer cylinder 11 has a second protruding ring 1111 inside, and the second protruding ring 1111 is coaxial with the first protruding ring 121. The first protruding ring 121 surrounds the second protruding ring 1111, or the second protruding ring 1111 surrounds the first protruding ring 121.

[0085] For example, such as Figure 8 As shown, the first convex ring 121 is fitted around the second convex ring 1111.

[0086] The technical solution provided in this embodiment makes the rotating sleeve 12 more stable when it rotates inside the outer cylinder 11 by setting the first convex ring 121 and the second convex ring 1111 of the ring sleeve.

[0087] In some examples, such as Figure 8 As shown, the second convex ring 1111 is located on the side of the bearing plate 111 facing the top of the outer cylinder 11.

[0088] In some examples, such as Figure 8As shown, the aforementioned limiting gap 130 is formed between the second protruding ring 1111 and the latching part 133.

[0089] In addition to the first protruding ring 121 and the second protruding ring 1111 of the ring sleeve, in some examples, the rotating sleeve 12 has a cylindrical structure and the outer cylinder 11 has a cylindrical receiving space. The outer wall of the rotating sleeve 12 contacts the inner wall of the outer cylinder 11, making the rotating sleeve 12 more stable when rotating.

[0090] In other examples, the rotating sleeve 12 has a rounded square column structure, and the outer cylinder 11 has a cylindrical receiving space. The four rounded corners of the outer wall of the rotating sleeve 12 contact the inner wall of the outer cylinder 11, which also makes the rotating sleeve 12 more stable when rotating.

[0091] This disclosure does not limit the implementation method of the circumferential limiting of the socket body 2 in the rotating sleeve 12. In some examples, such as Figure 10 As shown, the cross-section of the accommodating space of the rotating sleeve 12 and the cross-section of the socket body 2 are both rectangular. These rectangles can be rounded rectangles.

[0092] In this way, as the socket body 2 rotates, the socket body 2 can drive the rotating sleeve 12 to rotate together.

[0093] Of course, in other examples, protrusions and grooves can be provided on the socket body 2 and the rotating sleeve 12 respectively to limit the circumferential movement of the socket body 2 on the rotating sleeve 12.

[0094] This disclosure does not limit the connection method between the first fastener 4 and the rotating sleeve 12. In some examples, such as... Figure 11 As shown, the rotating sleeve 12 has a mounting base inside, and the first fastener 4 is inserted into the mounting base.

[0095] This disclosure does not limit the number of first fasteners 4. In some examples, there are multiple first fasteners 4, such as... Figure 11 As shown, there are two first fasteners 4, which are distributed opposite each other inside the rotating sleeve 12. This makes the socket body 2 more evenly stressed when the first fasteners 4 and the second fasteners 5 are locked, and can be more stable when retracted inside the rotating sleeve 12.

[0096] (3) In some examples, such as Figure 12As shown, the socket body 2 includes a socket body 21 and a sliding sleeve 22. The socket body 21 is rotatably connected to the sliding sleeve 22, and the socket body 21 is axially limited by the sliding sleeve 22. A first fastener 4 is fixedly connected to the receiving cylinder 1, and a second fastener 5 is fixedly connected to the sliding sleeve 22, with the first fastener 4 and the second fastener 5 facing each other. The sliding sleeve 22 is inserted into the receiving cylinder 1 and is circumferentially limited by the receiving cylinder 1. The socket body 21 and the sliding sleeve 22 can move up and down together relative to the receiving cylinder 1, and the socket body 21 can rotate relative to the sliding sleeve 22.

[0097] The technical solution provided in this embodiment allows the socket body 21 and the sliding sleeve 22 to rise and fall together relative to the receiving cylinder 1, and the socket body 21 to rotate relative to the sliding sleeve 22. As a result, the sliding sleeve 22 does not rotate during the rotation of the socket body 21. Consequently, the position of the second fastener 5, which is fixedly connected to the sliding sleeve 22, in the circumferential direction of the receiving cylinder 1 does not change. The second fastener 5 can always remain opposite to the first fastener 4, and the first fastener 4 and the second fastener 5 will not be misaligned.

[0098] In some examples, such as Figure 12 As shown, the top of the sliding sleeve 22 is lower than the socket portion of the socket body 21. This prevents the sliding sleeve 22 from obstructing the socket portion of the socket body 21.

[0099] It should be noted that for the lifting socket with rotating sleeve 12 and sliding sleeve 22, the first fastener 4 and the second fastener 5 can be any locking structure.

[0100] In some examples, the first fastener 4 and the second fastener 5 are elephant trunk lock structures, trash can lock structures (as shown in 11), or heart-shaped groove lock structures.

[0101] In the heart-shaped groove locking structure, one of the first fastener 4 and the second fastener 5 is a heart-shaped groove structure, and the other is a torsion spring. The end of the torsion spring has a hook that can move in the heart-shaped groove structure to hook onto or disengage from the heart-shaped groove structure, thereby achieving the locking and unlocking of the first fastener 4 and the second fastener 5.

[0102] It should also be noted that, since the socket body 2 is connected to a cable, in order to prevent the socket body 2 from rotating too much and causing the cable to twist, the lifting socket may also include a rotation limiting structure. The rotation limiting structure is located in the receiving cylinder 1 and / or the socket body 2 and is used to limit the rotation angle of the socket body 2.

[0103] Below, as Figure 13 As shown, taking the rotation limit between the base 01 and the rotating component 02 as an example, a possible implementation of the rotation limit structure is provided.

[0104] The rotation limiting structure includes a first stop 011 and a second stop 021. The first stop 011 is fixed to the base 01, and the second stop 021 is fixed to the rotating member 02. The first stop 011 is located on the rotation path of the second stop 021. The first stop 011 and the second stop 021 cooperate with each other to limit the rotation angle of the rotating member 02 relative to the base 01. Figure 13 As shown, the process of rotating member 02 rotating from one extreme position to another is illustrated.

[0105] Among them, the base 01 and the rotating component 02 are two parts that can detect relative rotation. In some examples, for Figure 2 In the case of the lifting socket shown, the base 01 is the receiving cylinder 1, and the rotating part 02 is the socket body 2.

[0106] In some examples, for Figure 6 In the illustrated lifting socket, the base 01 is the outer cylinder 11, and the rotating component 02 is the socket body 2. Alternatively, the base 01 is the outer cylinder 11, and the rotating component 02 is the rotating sleeve 12.

[0107] In some examples, for Figure 12 In the illustrated lifting socket, the base 01 is a sliding sleeve 22, and the rotating component 02 is the socket body 21. Alternatively, the base 01 is a receiving cylinder 1, and the rotating component 02 is the socket body 21.

[0108] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
