[0028] The present application embodiment provides a retractable socket, see Figure 1 and Figure 2 The telescopic socket includes a housing 10 , a winding bracket 20 and a power cord 30 .

[0029] The housing 10 has an inner cavity 10a and a wire outlet 10b communicating with the inner cavity 10a. The winding support 20 includes at least a wire winding portion 21 disposed within the inner cavity 10a. The power cord 30 includes a plug 31 located outside the housing 10 and a wire body 32 wound around the wire winding portion 21. The wire body 32 is connected to the plug 31 through the wire outlet 10b.

[0030] The housing 10 and the winding bracket 20 are rotatable relative to each other. The housing 10 rotates relative to the winding bracket 20 to achieve the retraction and extension of the wire 32 .

[0031] The inner cavity 10 a is used to accommodate the wire body 32 of the power wire 30 .

[0032] The inner cavity 10a is connected to the outside through the wire outlet 10b, and the wire body 32 extends out of the wire outlet 10b and is connected to the plug 31. That is, the wire outlet 10b is the inlet and outlet for the wire body 32 to extend from or retract from the inner cavity 10a.

[0033] The wire winding portion 21 is used to wind and store the wire 32. When the retractable socket is not needed, the wire 32 can be wound around the winding portion 21 as much as possible to minimize the length of the wire 32 extending outside the outlet 10b. When the retractable socket is needed, the wire 32 is pulled out of the inner cavity 10a to increase the length of the wire 32 extending outside the outlet 10b.

[0034] The wire 32 is retracted and extended by rotating the housing 10 relative to the winding frame 20. For example, pulling the wire 32 out of the inner cavity 10a can be accomplished in two ways: one is to rotate the housing 10 relative to the winding frame 20 in a direction opposite to the winding direction of the wire 32; the other is to directly apply a pulling force to the wire 32, causing the housing 10 to rotate relative to the winding frame 20 under the influence of the wire 32.

[0035] Correspondingly, there are two ways to retract the wire 32 into the inner cavity 10a. One way is to rotate the shell 10 relative to the winding bracket 20, and its rotation direction is the same as the winding direction of the wire 32. The other way is to apply a thrust to the wire 32 to make the shell 10 rotate accordingly.

[0036] Since the power cord 32 can be retracted and extended by rotating the housing 10 relative to the winding bracket 20, when using the retractable socket, the appropriate length of the power cord 32 can be pulled out from the outlet 10b by simply rotating the housing 10, while the remaining portion of the power cord 32 is stored within the housing 10, thereby making it easier to organize the power cord 30. In addition, when the retractable socket is no longer needed, the housing 10 can be rotated to store the power cord 32 as much as possible within the housing 10, making it easier for the user to carry the retractable socket.

[0037] In one embodiment, the housing 10 and the winding bracket 20 can be slidably matched to achieve relative rotation of the housing 10 and the winding bracket 20 .

[0038] That is to say, the shell 10 and the winding bracket 20 do not achieve relative rotation by providing a rotating shaft, but achieve relative rotation by sliding.

[0039] For example, see Figure 3 and Figure 4 The shell 10 may have a first sliding portion 11 arranged along the circumference of the inner cavity 10a, and the winding bracket 20 has a second sliding portion 22, and the first sliding portion 11 and the second sliding portion 22 are slidably matched.

[0040] That is, the first sliding portion 11 and the second sliding portion 22 are slidably engaged with each other so that the housing 10 can rotate relative to the winding bracket 20 .

[0041] It should be noted that, depending on the different structural forms of the first sliding part 11 and the second sliding part 22, some first sliding parts 11 and the second sliding parts 22 are only used for sliding cooperation, while some first sliding parts 11 and the second sliding parts 22, in addition to being used for sliding cooperation, can also serve to connect the winding bracket 20 with the shell 10.

[0042] The specific structural form of the first sliding portion 11 and the second sliding portion 22 is not limited, as long as they can slide together. For example, one of the first sliding portion 11 and the second sliding portion 22 can be a slider 111, and the other can be a slide groove 22a, and the slider 111 can slide into the slide groove 22a.

[0043] for example, Figure 3 and Figure 4 In the telescopic socket shown, the first sliding portion 11 is a slider 111 , and the second sliding portion 22 is a slide groove 22 a . That is, the slider 111 is provided on the housing 10 along the circumference of the inner cavity 10 a , and the slide groove 22 a is provided on the winding bracket 20 .

[0044] The slider 111 is slidably extended into the slide groove 22 a , that is, at least a portion of the slider 111 is located in the slide groove 22 a and can slide along the slide groove 22 a .

[0045] For example, see Figures 1 to 4 The winding bracket 20 may include a cover plate 23 arranged on one axial side of the winding portion 21 and a protrusion 24 arranged on the winding portion 21 along the circumference of the winding portion 21. The cover plate 23 and the protrusion 24 both protrude from the winding portion 21 along the radial direction of the winding portion 21 to form a slide groove 22a between the cover plate 23 and the protrusion 24.

[0046] The axial direction of the winding portion 21 refers to the extending direction of the rotation axis when the winding portion 21 and the housing 10 rotate relative to each other. The radial direction of the winding portion 21 is a direction perpendicular to the axial direction.

[0047] A sliding groove 22a is formed between the cover plate 23 and the protrusion 24, that is, the protrusion 24 is spaced apart from the cover plate 23 along the axial direction of the winding portion 21, and the slider 111 on the housing 10 extends between the cover plate 23 and the protrusion 24 and can rotate relative to the cover plate 23 and the protrusion 24.

[0048] For example, see Figure 3 and Figure 4 The protrusion 24 can be an elastic buckle. In other words, the slider 111 extends into the chute 22a by stretching the elastic buckle. After the slider 111 extends into the chute 22a, the elastic buckle deforms elastically, allowing the elastic buckle and the cover plate 23 to clamp the slider 111 together (it is understood that the clamping force of the elastic buckle and the cover plate 23 will not affect the sliding of the slider 111 in the chute 22a). As a result, the slider 111 can maintain contact with the elastic buckle and the cover plate 23 during the sliding process, thereby improving the sliding stability of the slider 111.

[0049] Please continue reading Figure 3 and Figure 4The winding portion 21 can be provided with an avoidance groove 21c corresponding to the elastic clip. When the slider 111 is inserted into the slide groove 22a, the elastic clip undergoes elastic deformation. By providing the avoidance groove 21c, the elastic clip can be provided with a relatively sufficient elastic deformation space, thereby facilitating the slider 111 to be inserted into the slide groove 22a.

[0050] In another embodiment, the first sliding portion 11 may be a sliding groove 22 a , and the second sliding portion 22 may be a sliding block 111 .

[0051] In one embodiment, one of the first sliding portion 11 and the second sliding portion 22 may be annular, and the other may be a plurality of the first sliding portion 11 and the second sliding portion 22 spaced apart along the sliding direction.

[0052] For example, see Figures 1 to 3 The first sliding portion 11 is annular, and the number of the second sliding portions 22 is multiple and spaced apart along the sliding direction. In other words, the first sliding portion 11 surrounds the circumference of the inner cavity 10a, and the multiple second sliding portions 22 all slide in cooperation with the first sliding portion 11.

[0053] Taking the first sliding portion 11 as the slider 111 and the second sliding portion 22 as the sliding groove 22a formed between the cover plate 23 and the protrusion 24 as an example, the slider 111 surrounds the circumference of the inner cavity 10a, and multiple sliding grooves 22a are formed between the cover plate 23 and the protrusion 24.

[0054] Specifically, see Figure 4 The winding bracket 20 has a plurality of protrusions 24 arranged at intervals along the sliding direction, thereby forming a plurality of slide grooves 22a between the cover plate 23 and the protrusions 24. Since the slider 111 surrounds the circumference of the inner cavity 10a, that is, when the slider 111 slides and rotates in the slide groove 22a, the slider 111 is always located in the slide groove 22a, preventing the slider 111 from escaping from the slide groove 22a.

[0055] In another embodiment, the first sliding portion 11 may be a plurality of first sliding portions 11 spaced apart along the sliding direction, and the second sliding portion 22 may be annular.

[0056] In another embodiment, the first sliding portion 11 and the second sliding portion 22 may both be annular, thereby improving the matching stability of the first sliding portion 11 and the second sliding portion 22 .

[0057] In another embodiment, the first sliding portion 11 and the second sliding portion 22 may not be provided. For example, the winding stent 20 may directly slide in contact with the inner wall of the inner cavity 10a.

[0058] In addition, it should be noted that the shell 10 and the winding bracket 20 are not limited to achieving relative rotation between the shell 10 and the winding bracket 20 by sliding cooperation. In other embodiments, the shell 10 and the winding bracket 20 can achieve relative rotation by connecting with a rotating shaft.

[0059] In one embodiment, please refer to Figure 4 The outer peripheral side of the winding portion 21 may have a winding track 21 a that is recessed in a direction away from the housing 10 , and the wire body 32 is wound around the winding track 21 a .

[0060] When the wire 32 is wound on the winding track 21 a , at least a portion of the structure of the wire 32 is located within the winding track 21 a . Therefore, the winding track 21 a can play a certain role in positioning and / or limiting the wire 32 .

[0061] For example, please refer to Figure 4 The winding track 21 a may extend spirally along the circumference of the winding portion 21 .

[0062] The spiral extension means that the winding track 21 a extends along a certain spiral line on the surface of the winding portion 21 .

[0063] The wire body 32 is spirally wound on the winding portion 21 along the winding track 21 a , so that the wire body 32 can be wound on the winding portion 21 in an orderly manner, thereby improving the user's experience.

[0064] Preferably, the shape and dimensions of the wire body 32 can match those of the winding track 21 a , so that the wire body 32 is not easily dislodged from the winding track 21 a , thereby allowing the winding track 21 a to further position and / or limit the wire body 32 .

[0065] Preferably, the maximum distance between the winding portion 21 and the winding track 21a can be slightly larger than the size of the cross-section of the wire body 32, thereby preventing interference between the wire body 32 and the shell 10 and affecting the relative rotation of the shell 10, and further preventing the wire body 32 from escaping from the winding track 21a through the shell 10.

[0066] In another embodiment, the wire body 32 may also be wound from inside to outside along the radial direction of the winding portion 21 .

[0067] In one embodiment, please refer to Figures 1 to 4 One axial side of the shell 10 may have an opening 10c connected to the inner cavity 10a, and the winding bracket 20 includes a cover plate 23 arranged on one axial side of the winding portion 21 and having an insertion hole 23a, and the cover plate 23 is covered at the opening 10c.

[0068] The winding portion 21 can be placed into the inner cavity 10a from the opening 10c. The cover plate 23 can not only close the opening 10c, but also be used to set the insertion hole 23a.

[0069] The insertion hole 23a is a hole for inserting a plug of a power supply device.

[0070] The shell 10 and the winding bracket 20 can rotate relative to each other, so the shell 10 can rotate relative to the cover 23. Therefore, when the wire body 32 is retracted or released, the cover 23 can be fixed, and when the plug of the electrical device is inserted into the socket 23a, it is convenient for users to use.

[0071] For example, see Figure 1 and Figure 2 The winding portion 21 may be formed with a cavity 21b communicating with the plug hole 23a, and the telescopic socket includes an electric control board 40, which is disposed in the cavity 21b.

[0072] The cavity 21b is used to accommodate the electric control board 40. Placing the electric control board 40 in the cavity 21b not only saves space in the inner cavity 10a and helps reduce the volume of the housing 10, but also reduces the weight of the telescopic socket, making the telescopic socket easy to carry and use.

[0073] Please continue reading Figure 1 and Figure 2 The telescopic bracket may further include a safety door assembly 50 , which is disposed between the plug hole 23 a and the electric control board 40 .

[0074] The safety door assembly 50 can be used to prevent foreign objects from entering the plug hole 23a, and can also prevent the user's fingers from entering the plug hole 23a and causing electric shock.

[0075] For example, the safety door assembly 50 can be provided with spring-loaded baffles corresponding to the plug holes 23a. Before the electrical device plug is inserted into the plug hole 23a, the spring-loaded baffles shield the plug hole 23a to provide protection. When the electrical device plug is inserted into the plug hole 23a, the metal sheet on the power plug 31 simultaneously pushes the corresponding spring-loaded baffle. After the spring-loaded baffle is removed from the plug hole 23a, the metal sheet is electrically connected to the electrical control board 40, thereby energizing the device.

[0076] In one embodiment, please refer to Figure 2 The telescopic socket may further include an anti-slip pad 60 , which is disposed on a side of the housing 10 facing away from the outlet 10 c.

[0077] The anti-skid pad 60 is used to increase the friction between the telescopic socket and a placement surface such as a desktop or the ground, so that the telescopic socket is not likely to slide when placed on the placement surface.

[0078] The material of the anti-slip pad 60 is not limited. For example, the anti-slip pad 60 can be made of silicone. The anti-slip pad 60 made of silicone not only has good anti-slip performance but also has a long service life.

[0079] Since the anti-slip pad 60 is located on the side of the shell 10 away from the opening 10c, that is, when the telescopic socket is placed on the placement surface, the cover plate 23 is located on the side of the shell 10 away from the placement surface, which makes it convenient for users to insert the plug of the electrical device into the socket 23a.
