Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment, more particularly, it relates to an embedded anti-electric shock socket. BACKGROUND

[0002] The socket, also known as a power socket or a switch socket, is an electrical device that provides a power interface for electrical appliances. Traditional sockets are usually arranged on the wall surface. In order to make the arrangement of the socket more flexible and convenient for electrical appliance connection, a lifting socket appears.

[0003] At present, the lifting socket market is rapidly growing with the popularization of smart home and the promotion of urbanization. Among them, the embedded product occupies an important share in high-end residential, hotel guest room and business office scenes due to its hidden power supply and space saving characteristics.

[0004] The lifting socket in the prior art is always on during movement, which makes the user adjust the position of the socket at risk of touching the live part by mistake. Moreover, some products rely on flexible wires or sliding contacts to maintain power-on, and repeated stretching of the line causes the insulation layer to age or even short circuit.

[0005] For example, Chinese Patent No. 2021228152142, published on April 8, 2022, the name of the invention is a lifting socket. The application discloses a lifting socket which mainly reduces the shaking of the containing cylinder during the up and down movement of the lifting socket through the first guide structure and the second guide structure. However, it is easy to stretch or squeeze the wire during the lifting process. Moreover, the socket remains in the power-on state during the lifting process, which poses a risk of touching the live part by mistake. SUMMARY

[0006] The present application overcomes the two shortcomings in the prior art: (1) the circuit of the lifting socket is always on during movement, which makes the user adjust the position of the socket at risk of touching the live part by mistake; (2) it relies on flexible wires or sliding contacts to maintain power-on, and repeated stretching of the line accelerates the aging of the insulation layer, resulting in short circuit. The present application provides an embedded anti-electric shock socket which can maintain a power-off state during the sliding of the socket inner cylinder, and maintain a power-on state when the socket inner cylinder is in the contact position, thereby avoiding the risk of electric shock during the sliding of the socket inner cylinder. In addition, during the sliding of the socket inner cylinder, the contact remains disconnected, and the wire will not be stretched or squeezed, thereby avoiding the problem of accelerated aging of the insulation layer caused by repeated stretching of the line.

[0007] To solve the above technical problems, the present application adopts the following technical scheme: an embedded anti-electric shock socket, comprising:

[0008] A mounting outer cylinder is provided with a plurality of fixed contacts inside;

[0009] The socket inner cylinder is provided with movable contacts matched with several fixed contacts; when the fixed contacts are in contact with or separated from the movable contacts during the sliding of the socket inner cylinder in the mounting outer cylinder, the socket inner cylinder is in a power-on or power-off state.

[0010] When the socket inner cylinder in the application slides to a specific position of the mounting outer cylinder, the movable contacts will be in contact with the fixed contacts, and the socket inner cylinder at this time will be in a power-on state. During the sliding of the socket inner cylinder along the mounting outer cylinder, the movable contacts are separated from the fixed contacts, and the socket inner cylinder at this time is in a power-off state, which ensures that there is no electric shock when adjusting the socket inner cylinder during use. Since the fixed contacts are fixedly arranged in the mounting outer cylinder, the external wires can be connected with the fixed contacts, so that the wires will not move with the movement of the socket inner cylinder during the sliding of the socket inner cylinder, preventing the wires from aging and breaking due to stretching and bending.

[0011] Preferably, several conductive strips are arranged along the axial direction of the mounting outer cylinder; the fixed contacts are arranged on the conductive strips.

[0012] Through the above structure, as long as the conductive strips are powered on with external wires, all the fixed contacts on the entire conductive strip can be powered on.

[0014] When the socket inner cylinder slides along the mounting outer cylinder, the guide sleeve slides along the guide column, improving the stability of the socket inner cylinder during sliding. At the same time, the conductive strips are arranged on the side wall of the guide column, and the movable contacts are arranged on the inner side wall of the guide sleeve, making the overall structure more compact.

[0017] Preferably, the fixed contact is a conductive protrusion protruding on the conductive strip, and the conductive protrusion is integrally formed with the conductive strip.

[0018] The integrally formed conductive protrusion and conductive strip can reduce the processing cost, and compared with the separated fixed contacts, the fixed contacts and the conductive strip can be in a power-on state.

[0020] The sliding limiting openings matched with the lifting limiting ribs can improve the stability between the socket inner cylinder and the mounting outer cylinder, so that the socket inner cylinder can slide in the mounting outer cylinder more stably.

[0021] Preferably, the inner wall of the mounting outer cylinder is provided with a plurality of inner cylinder limiting members in the circumferential direction thereof; when the socket inner cylinder slides to the top end position of the mounting outer cylinder, the sliding limiting blocks abut against the inner cylinder limiting members.

[0022] The inner cylinder limiting members can limit the sliding limiting blocks, thereby achieving the fixed limiting of the socket inner cylinder.

[0023] Preferably, the side of the sliding limiting block close to the inner cylinder limiting member is provided with an inner cylinder positioning hole, and the bottom of the inner cylinder limiting member is provided with an inner cylinder positioning column matched with the inner cylinder positioning hole; when the socket inner cylinder slides to the top end position of the mounting outer cylinder, the inner cylinder positioning column is in interference fit with the inner cylinder positioning hole.

[0024] The inner cylinder positioning hole and the inner cylinder positioning column form a top positioning structure. When the socket inner cylinder is completely extended out of the mounting outer cylinder, the inner cylinder positioning column is inserted into the inner cylinder positioning hole, and the inner cylinder positioning column is in interference fit with the inner cylinder positioning hole, thereby preventing the socket inner cylinder from sliding downward. At this time, the movable contact is combined with the second contact group, and the socket inner cylinder remains in the powered state.

[0025] Preferably, the fixed contact includes two contact groups, i.e., a first contact group and a second contact group, and the first contact group and the second contact group are arranged along the axial direction of the mounting outer cylinder; when the socket inner cylinder slides to the bottom end position of the mounting outer cylinder, the movable contact is combined with the first contact group; when the socket inner cylinder slides to the top end position of the mounting outer cylinder, the movable contact is combined with the second contact group.

[0027] Preferably, a buckle assembly is arranged at the bottom of the socket inner cylinder and the bottom of the mounting outer cylinder, and the buckle assembly is matched with each other when the socket inner cylinder is located at the bottom end of the mounting outer cylinder.

[0029] Compared with the prior art, the beneficial effects of the present application are that the socket inner cylinder is kept in a power-on state only when it is lifted to a specific preset point, and the risk of electrification during movement of the socket inner cylinder can be completely eliminated. Compared with the traditional technology which relies on flexible wires to move with the socket inner cylinder or adopts a dynamic sliding contact to maintain conduction, the present application fixes the strong current module on the socket inner cylinder, only the socket inner cylinder moves during lifting, and the circuit is closed only when the socket inner cylinder is lifted to the highest point or lowered to the lowest point, avoiding line stretching and wear and tear, physical deformation.

[0046] The technical solutions of the present application will be further described in detail below through specific embodiments and in combination with the drawings:

[0047] Example 1: Referring to Figures 1 to 7 As shown in the figure, an embedded anti-electric shock socket includes an installation outer cylinder 1 and a socket inner cylinder 2.

[0048] The inside of the installation outer cylinder 1 is provided with a plurality of fixed contacts 11, which are fixedly arranged inside the installation outer cylinder 1.

[0049] The socket inner cylinder 2 is provided with movable contacts 21 that cooperate with the plurality of fixed contacts 11, and the movable contacts 21 move as the socket inner cylinder 2 slides in the installation outer cylinder 1; during the sliding process of the socket inner cylinder 2 in the installation outer cylinder 1, the fixed contacts 11 and the movable contacts 21 are in contact or separated, and the socket inner cylinder 2 is in a power-on or power-off state.

[0050] When the socket inner cylinder 2 in the present application slides to a specific position of the mounting outer cylinder 1, the movable contact 21 will be in contact with the fixed contact 11, at this time, the socket inner cylinder 2 is in a state of being powered on. During the process of the socket inner cylinder 2 sliding along the mounting outer cylinder 1, the movable contact 21 is separated from the fixed contact 11, at this time, the socket inner cylinder 2 is in a state of being powered off, which ensures that there is no electric shock when adjusting the socket inner cylinder 2. And because the fixed contact 11 is fixedly arranged in the mounting outer cylinder 1, the external wire can be connected with the fixed contact 11, so during the process of the socket inner cylinder 2 sliding, the wire will not move with the socket inner cylinder 2, preventing the wire from aging and breaking due to stretching and bending.

[0051] In one embodiment, the fixed contact 11 includes two groups, namely the first contact group 111 and the second contact group 112, and the first contact group 111 and the second contact group 112 are arranged along the axis direction of the mounting outer cylinder 1. When the socket inner cylinder 2 slides to the bottom end position of the mounting outer cylinder 1, the movable contact 21 is in contact with the first contact group 111. When the socket inner cylinder 2 slides to the top end position of the mounting outer cylinder 1, the movable contact 21 is in contact with the second contact group 112.

[0052] The fixed contact 11 can be arranged in several groups. In the present embodiment, the fixed contact 11 is arranged in two groups. When the socket inner cylinder 2 slides to the bottom of the mounting outer cylinder 1, the socket inner cylinder 2 is embedded in the mounting outer cylinder 1 at this time, the movable contact 21 is in contact with the first contact group 111 at this time, the socket inner cylinder 2 is in a state of being powered on, and the wireless charging assembly arranged at the top of the socket inner cylinder 2 can be normally used. When the socket inner cylinder 2 slides to the top of the mounting outer cylinder 1, the socket inner cylinder 2 extends the maximum distance at this time, the movable contact 21 is in contact with the second contact group 112 at this time, and the socket inner cylinder 2 is also in a state of being powered on, and the socket inner cylinder 2 on the socket inner cylinder 2, namely the wireless charging assembly, can be normally used.

[0053] Of course, the fixed contact 11 can also be arranged in three groups or four groups, and several groups of fixed contacts 11 are arranged along the axis direction of the mounting outer cylinder 1. When the socket inner cylinder 2 extends every distance from the mounting outer cylinder 1, the corresponding contact group will be in contact with the movable contact 21, and several circles of jack sides 22 can be arranged on the outer side wall of the socket inner cylinder 2, so that the more jacks are extended as the socket inner cylinder 2 extends every distance from the mounting outer cylinder 1.

[0054] There are several jack sides 22 for arranging jacks on the outer side wall of the socket inner cylinder 2, and the number of jack sides 22 is arranged according to the diameter of the socket inner cylinder 2. In the present application, four jack sides 22 are arranged on the outer side wall of the socket inner cylinder 2. Different types of jacks can be arranged on the jack side 22 as needed.

[0055] In one embodiment, a plurality of conductive strips 3 are arranged along the axial direction of the installation outer cylinder 1, and the fixed contacts 11 are arranged on the conductive strips 3. Therefore, as long as the conductive strips 3 are electrified with external wires, all the fixed contacts 11 on the entire conductive strips 3 can be electrified.

[0056] A bottom end connecting strip 31 is arranged at the bottom of the conductive strip 3 to facilitate the connection with external wires. Therefore, only the external wires need to be connected with the bottom end connecting strip 31, and then the entire conductive strip 3 can be electrified, and the bottom end connecting strip 31 can facilitate the connection of external wires with the conductive strip 3.

[0057] The number of the conductive strips 3 can be set according to actual needs. In the embodiment, three conductive strips 3 are arranged, and the three conductive strips 3 are connected with the neutral wire, the live wire and the ground wire, respectively. Meanwhile, the corresponding movable contacts 21 on the socket inner cylinder 2 are also arranged in three, and the three movable contacts 21 correspond to one conductive strip 3, respectively.

[0058] As shown in Figure 4 three conductive strips 3 are arranged with one fixed contact 11 at the bottom and the top, respectively. The fixed contacts 11 at the bottom of the three conductive strips 3 form a first contact group 111, and the fixed contacts 11 at the top of the three conductive strips 3 form a second contact group 112. Therefore, when multiple contact groups need to be arranged, the fixed contacts 11 can be arranged at the corresponding height positions of the conductive strips 3.

[0059] The fixed contact 11 is a conductive protrusion 32 protruding on the conductive strip 3, and the conductive protrusion 32 is integrally formed with the conductive strip 3. The integrally formed conductive protrusion 32 and the conductive strip 3 can reduce the processing cost, and compared with the separated fixed contact 11, the fixed contact 11 and the conductive strip 3 can be kept in an electrified state.

[0060] During the sliding of the movable contact 21 along the conductive strip 3, there is a gap between the conductive strip 3 and the movable contact 21, and the movable contact 21 does not contact the conductive strip 3. When the movable contact 21 moves to the position of the conductive protrusion 32, the movable contact 21 will contact the conductive protrusion 32 because the conductive protrusion 32 protrudes on the surface of the conductive strip 3.

[0061] In one embodiment, a guide column 12 is arranged inside the installation outer cylinder 1 along the axial direction of the installation outer cylinder 1, and a plurality of conductive strips 3 are arranged in the circumferential direction of the guide column 12. The bottom of the socket inner cylinder 2 is provided with a guide sleeve 23 matched with the guide column 12, and a plurality of movable contacts 21 are arranged on the inner side wall of the guide sleeve 23.

[0062] The socket inner cylinder 2 slides along the mounting outer cylinder 1 while the guide sleeve 23 slides along the guide column 12, improving the stability of the socket inner cylinder 2 when sliding. At the same time, the conductive strip 3 is mounted on the side wall of the guide column 12, and the movable contact 21 is arranged on the inner side wall of the guide sleeve 23, so that the overall structure can be more compact. In order to facilitate the installation of the conductive strip 3, a plurality of mounting grooves are arranged on the outer side wall of the guide column 12 in the axial direction, and the conductive strip 3 is directly inserted into the mounting groove, which facilitates the installation of the conductive strip 3 and also plays a limiting role on the conductive strip 3; correspondingly, the inner side wall of the guide sleeve 23 is also provided with a mounting groove, and the movable contact 21 is also inserted into the mounting groove.

[0063] In one embodiment, the mounting outer cylinder 1 is provided with a plurality of lifting limiting ribs 13 arranged in the axial direction, and the outer side wall of the socket inner cylinder 2 is provided with a plurality of sliding limiting blocks 4 matched with the lifting limiting ribs 13, and the sliding limiting blocks 4 are provided with sliding limiting openings 41 matched with the lifting limiting ribs 13.

[0064] The sliding limiting openings 41 matched with the lifting limiting ribs 13 can improve the stability between the socket inner cylinder 2 and the mounting outer cylinder 1, so that the socket inner cylinder 2 can slide more stably in the mounting outer cylinder 1. At the same time, the top of the lifting limiting rib 13 is provided with an inner cylinder limiting piece 14, and when the socket inner cylinder 2 slides to the top position along the mounting outer cylinder 1, the sliding limiting block 4 abuts against the inner cylinder limiting piece 14.

[0065] The number of the inner cylinder limiting piece 14 and the number of the lifting limiting rib 13 in the embodiment are set according to specific conditions, and in order to improve the stability of the socket inner cylinder 2 when sliding, a sliding limiting block 4 is arranged at the bottom of each jack side surface 22. Therefore, the sliding limiting block 4 in the embodiment is provided with four, and the corresponding lifting limiting rib 13 is also provided with four.

[0066] In one embodiment, the bottom of the mounting outer cylinder 1 is provided with an outer cylinder base 15, the guide column 12 is fixedly arranged on the outer cylinder base 15, and the guide column 12 is arranged at the axial position of the outer cylinder base 15. The overload protection 151 and the power line outlet 152 are also arranged on the outer cylinder base 15, and the external power cord is connected with the bottom end connecting strip 31 through the power line outlet 152.

[0067] In one embodiment, a desktop limiting ring 5 is arranged on the periphery of the installation outer cylinder 1, and a screw ring 51 is further arranged on the outer side of the desktop limiting ring 5. The installation outer cylinder 1 is threadedly connected with the desktop limiting ring 5, and the relative height between the installation outer cylinder 1 and the desktop limiting ring 5 can be adjusted. When the socket inner cylinder 2 is lifted to the highest position, the height from the top of the socket inner cylinder 2 to the desktop is 237 mm. After the socket inner cylinder 2 is accommodated in the desktop, the distance from the top of the socket inner cylinder 2 to the desktop is about 76 mm, which provides sufficient space for the use of common chargers. The distance between the socket of the lifted socket inner cylinder 2 and the desktop also provides a certain distance, which reduces the possibility of liquid flowing into the socket and improves the safety of the socket.

[0068] In one embodiment, a pneumatic lifting rod 6 is arranged at the middle position of the guide column 12, and the telescopic end of the pneumatic lifting rod 6 is connected with the socket inner cylinder 2. The lifting of the socket inner cylinder 2 can be realized by the telescopic movement of the pneumatic lifting rod 6.

[0069] In one embodiment, a strong current module 16 and a weak current module 17 are arranged in the socket inner cylinder 2. The socket corresponding to the strong current module 16 is used to connect high-power equipment such as computers and table lamps, and the socket corresponding to the weak current module 17 is used to connect low-power equipment such as mobile phones and tablets. The use efficiency is improved, the power consumption of each side is limited, the overload risk is reduced, the plugs do not interfere with each other, and an overload protection 151 is arranged on the base to further improve the safety.

[0070] The present application only keeps the socket inner cylinder 2 powered when it is lifted to a specific preset point, which can completely eliminate the risk of live wire during the movement of the socket inner cylinder 2. Compared with the traditional technology which relies on flexible wires to move with the socket inner cylinder 2 or uses dynamic sliding contacts to maintain conduction, the present application fixes the strong current module 16 on the socket inner cylinder 2, only moves the socket inner cylinder 2 during lifting, and only closes the circuit when the socket inner cylinder 2 is lifted to the highest point or lowered to the lowest point, avoiding line stretching and wear and physical deformation.

[0071] In addition, the traditional scheme has a complex structure. The present application focuses on fixing the strong current module 16 and the socket inner cylinder 2, arranging the strong current module 16 on the socket inner cylinder 2, controlling the power supply of the socket inner cylinder 2 through the contact between the movable contact 21 and the fixed contact 11, and realizing the on-off control through a pure trigger structure without the need for a motor or a sensor. The layered positioning structure ensures accurate alignment of the contacts, reduces the complexity and failure rate of the structure, simplifies the production, assembly and processing process, reduces the manufacturing cost, and improves the practicability.

[0072] In this embodiment, the positioning structure is similar to that in Embodiment 1, except that a positioning structure is arranged between the socket inner cylinder 2 and the mounting outer cylinder 1 to enable the fixed contact 11 and the movable contact 21 to be in contact when the socket inner cylinder 2 is inserted into the mounting outer cylinder 1.

[0073] The positioning structure in this application includes a bottom positioning structure and a top positioning structure.

[0074] The bottom positioning structure enables the socket inner cylinder 2 and the mounting outer cylinder 1 to be connected and positioned when the socket inner cylinder 2 is inserted into the mounting outer cylinder 1. The bottom positioning structure includes a buckle assembly arranged at the bottom of the mounting outer cylinder 1 and the bottom of the socket inner cylinder 2. In this embodiment, a plurality of buckling heads 61 are arranged at the bottom of the socket inner cylinder 2, and a plurality of buckling holes 62 matched with the buckling heads 61 are arranged at the bottom of the mounting outer cylinder 1.

[0075] When the socket inner cylinder 2 is inserted into the mounting outer cylinder 1, the buckling heads 61 are inserted into the buckling holes 62, and the buckling holes 62 limit the buckling heads 61. At this time, the first contact group 111 and the movable contact 21 are in contact with each other, the socket inner cylinder 2 is in a powered state, and the wireless charging assembly at the top of the socket inner cylinder 2 can charge the device placed thereon.

[0076] In one embodiment, the sliding limiting block 4 is provided with an inner cylinder positioning hole 42 on one side close to the inner cylinder limiting piece 14, and the inner cylinder limiting piece 14 is provided with an inner cylinder positioning column 141 matched with the inner cylinder positioning hole 42; when the socket inner cylinder 2 slides to the top end position along the mounting outer cylinder 1, the inner cylinder positioning column 141 is in interference fit with the inner cylinder positioning hole 42.

[0077] The inner cylinder positioning hole 42 and the inner cylinder positioning column 141 form a top positioning structure. Thus, when the socket inner cylinder 2 is completely extended out of the mounting outer cylinder 1, the inner cylinder positioning column 141 is inserted into the inner cylinder positioning hole 42, and the inner cylinder positioning column 141 is in interference fit with the inner cylinder positioning hole 42 to prevent the socket inner cylinder 2 from sliding downward. At this time, the movable contact 21 is in contact with the second contact group 112, and the socket inner cylinder 2 remains in a powered state.

[0078] Embodiment 3: This embodiment is similar to the structure in Embodiment 1 or Embodiment 2, except that the positioning structure in this embodiment is arranged on the fixed contact 11 and the movable contact 21. Specifically, a plurality of horizontal protruding ribs 7 (as shown in the figure) are arranged on the conductive convex part 32 and the movable contact 21 in this embodiment. Figure 5As shown in the figure, the conductive protrusion 32 and the movable contact 21 are both set as metal conductive sheets. Through external force, the limiting effect of the protrusions 7 can be overcome, so that the conductive protrusion 32 and the movable contact 21 slide with each other, and when the conductive protrusion 32 is attached to the movable contact 11, the protrusions 7 on the conductive protrusion 32 and the movable contact 21 are staggered and overlapped, at this time, the socket inner cylinder 2 and the mounting outer cylinder 1 can be kept relatively stationary, that is, through the protrusions 7 set on the conductive protrusion 32 and the movable contact 21, the positioning of the socket inner cylinder 2 can be realized.

[0079] Embodiment 4: Refer to Figures 1 to 7 As shown in the figure, an embedded anti-electric shock socket includes a mounting outer cylinder 1 and a socket inner cylinder 2.

[0080] The inside of the mounting outer cylinder 1 is provided with a plurality of fixed contacts 11, which are fixedly arranged inside the mounting outer cylinder 1.

[0081] The socket inner cylinder 2 is provided with a movable contact 21 cooperating with the plurality of fixed contacts 11, and the movable contact 21 moves with the sliding of the socket inner cylinder 2 in the mounting outer cylinder 1; during the sliding of the socket inner cylinder 2 in the mounting outer cylinder 1, the fixed contact 11 and the movable contact 21 are attached or separated, and the socket inner cylinder 2 is in a corresponding power-on or power-off state.

[0082] In the present application, when the socket inner cylinder 2 slides to a specific position of the mounting outer cylinder 1, the movable contact 21 will be attached to the fixed contact 11, and at this time, the socket inner cylinder 2 will be in a power-on state. During the sliding of the socket inner cylinder 2 along the mounting outer cylinder 1, the movable contact 21 is separated from the fixed contact 11, and at this time, the socket inner cylinder 2 is in a power-off state, which ensures that during use, electric shock does not occur when adjusting the socket inner cylinder 2. And because the fixed contact 11 is fixedly arranged in the mounting outer cylinder 1, the external wire can be connected to the fixed contact 11, so that during the sliding of the socket inner cylinder 2, the wire will not move with the movement of the socket inner cylinder 2, preventing the wire from aging and breaking due to stretching and bending.

[0083] In one embodiment, the fixed contact 11 includes two groups, namely a first contact group 111 and a second contact group 112, which are arranged along the axis direction of the mounting outer cylinder 1; when the socket inner cylinder 2 slides to the bottom end position along the mounting outer cylinder 1, the movable contact 21 is attached to the first contact group 111; when the socket inner cylinder 2 slides to the top end position along the mounting outer cylinder 1, the movable contact 21 is attached to the second contact group 112.

[0084] The fixed contacts 11 can be arranged in several groups. In the embodiment, the fixed contacts 11 are arranged in two groups. When the socket inner cylinder 2 slides to the bottom of the mounting outer cylinder 1, the socket inner cylinder 2 is embedded in the mounting outer cylinder 1 at this time, the movable contact 21 at this time is in contact with the first contact group 111, the socket inner cylinder 2 at this time is in a powered state, and the wireless charging assembly arranged at the top of the socket inner cylinder 2 can be normally used. When the socket inner cylinder 2 slides to the top of the mounting outer cylinder 1, the socket inner cylinder 2 at this time extends outward by the maximum distance, the movable contact 21 at this time is in contact with the second contact group 112, the socket inner cylinder 2 at this time is also in a powered state, and the socket jack on the socket inner cylinder 2, i.e., the wireless charging assembly, can be normally used.

[0085] Of course, the fixed contacts 11 can also be arranged in three groups or four groups. The fixed contacts 11 arranged in several groups are arranged along the axial direction of the mounting outer cylinder 1. When the socket inner cylinder 2 extends by each distance from the mounting outer cylinder 1, the corresponding contact group is in contact with the movable contact 21. Meanwhile, a plurality of jack sides 22 for arranging the jacks are arranged on the outer side wall of the socket inner cylinder 2, so that the more jacks are extended as the socket inner cylinder 2 extends by each distance from the mounting outer cylinder 1.

[0086] A plurality of jack sides 22 for arranging the jacks are arranged on the outer side wall of the socket inner cylinder 2. The number of the jack sides 22 is arranged according to the diameter of the socket inner cylinder 2. In the application, four jack sides 22 are arranged on the outer side wall of the socket inner cylinder 2. Different types of jacks can be arranged on the jack sides 22 as needed.

[0087] In one embodiment, a plurality of conductive strips 3 are arranged along the axial direction of the mounting outer cylinder 1 in the mounting outer cylinder 1, and the fixed contacts 11 are arranged on the conductive strips 3. Therefore, as long as the conductive strips 3 are powered by the external wires, all the fixed contacts 11 on the entire conductive strip 3 can be powered.

[0088] A bottom end connecting strip 31 for facilitating the connection with the external wires is arranged at the bottom of the conductive strip 3. Therefore, the external wires only need to be connected with the bottom end connecting strip 31, and then the entire conductive strip 3 can be powered. The bottom end connecting strip 31 can facilitate the connection of the external wires with the conductive strip 3 for power supply.

[0089] The number and quantity of the conductive strips 3 can be arranged according to actual needs. In the embodiment, three conductive strips 3 are arranged, and the three conductive strips 3 are connected with the neutral wire, the live wire and the ground wire, respectively. Meanwhile, the corresponding movable contacts 21 on the socket inner cylinder 2 are also arranged in three groups, and the three movable contacts 21 correspond to one conductive strip 3, respectively.

[0090] As Figure 4As shown, a fixed contact 11 is arranged at the bottom and top of each of the three conductive strips 3, and the fixed contacts 11 at the bottom of the three conductive strips 3 form a first contact group 111, and the fixed contacts 11 at the top of the three conductive strips 3 form a second contact group 112. Therefore, when multiple contact groups are needed, the fixed contacts 11 can be arranged at the corresponding height of the conductive strips 3.

[0091] The fixed contact 11 is a conductive protrusion 32 protruding on the conductive strip 3, and the conductive protrusion 32 is integrally formed with the conductive strip 3. The integrally formed conductive protrusion 32 and the conductive strip 3 can reduce the cost of processing, and compared with the separated fixed contact 11, the fixed contact 11 and the conductive strip 3 can be in a power-on state.

[0092] During the sliding of the movable contact 21 along the conductive strip 3, there is a gap between the conductive strip 3 and the movable contact 21, and the movable contact 21 will not contact the conductive strip 3. When the movable contact 21 moves to the position of the conductive protrusion 32, the movable contact 21 will contact the conductive protrusion 32 because the conductive protrusion 32 protrudes on the surface of the conductive strip 3.

[0093] In one embodiment, a guide column 12 is arranged inside the mounting outer cylinder 1 along the axial direction, and a plurality of conductive strips 3 are arranged in the circumferential direction of the guide column 12; the bottom of the socket inner cylinder 2 is provided with a guide sleeve 23 matched with the guide column 12, and a plurality of movable contacts 21 are arranged on the inner side wall of the guide sleeve 23.

[0094] When the socket inner cylinder 2 slides along the mounting outer cylinder 1, the guide sleeve 23 slides along the guide column 12, which improves the stability of the socket inner cylinder 2 during sliding. At the same time, the conductive strips 3 are arranged on the side wall of the guide column 12, and the movable contacts 21 are arranged on the inner side wall of the guide sleeve 23, so that the overall structure can be more compact. In order to facilitate the installation of the conductive strips 3, a plurality of mounting grooves are arranged on the outer side wall of the guide column 12 along the axial direction, and the conductive strips 3 are directly inserted into the mounting grooves, which facilitates the installation of the conductive strips 3 and also limits the position of the conductive strips 3; correspondingly, mounting grooves are also arranged on the inner side wall of the guide sleeve 23, and the movable contacts 21 are also inserted into the mounting grooves.

[0095] In one embodiment, a plurality of lifting limiting ribs 13 are arranged on the inner side wall of the mounting outer cylinder 1 along the axial direction, and a plurality of sliding limiting blocks 4 matched with the lifting limiting ribs 13 are arranged on the outer side wall of the socket inner cylinder 2, and the sliding limiting blocks 4 are provided with sliding limiting openings 41 matched with the lifting limiting ribs 13.

[0096] The sliding limiting port 41 cooperates with the lifting limiting rib 13, which can improve the stability between the socket inner cylinder 2 and the mounting outer cylinder 1, so that the socket inner cylinder 2 can slide more stably in the mounting outer cylinder 1. Meanwhile, the inner cylinder limiting piece 14 is arranged at the top of the lifting limiting rib 13, and when the socket inner cylinder 2 slides to the top position along the mounting outer cylinder 1, the sliding limiting block 4 abuts against the inner cylinder limiting piece 14.

[0097] The number of the inner cylinder limiting piece 14 and the number of the lifting limiting rib 13 in the embodiment are set according to specific conditions, and in order to improve the stability of the socket inner cylinder 2 during sliding, one sliding limiting block 4 is arranged at the bottom of each jack side surface 22. Therefore, the sliding limiting block 4 in the embodiment is provided with four, and the corresponding lifting limiting rib 13 is also provided with four.

[0098] In one of the embodiments, the bottom of the mounting outer cylinder 1 is provided with an outer cylinder base 15, the guide column 12 is fixedly arranged on the outer cylinder base 15, and the guide column 12 is arranged at the axis position of the outer cylinder base 15. The overload protection 151 and the power line outlet 152 are also arranged on the outer cylinder base 15, and the external power line is connected with the bottom end connecting strip 31 through the power line outlet 152.

[0099] In one of the embodiments, the desktop limiting ring 5 is arranged on the periphery of the mounting outer cylinder 1, and the outside of the desktop limiting ring 5 is further provided with a hand ring 51. The mounting outer cylinder 1 and the desktop limiting ring 5 are threadedly connected, and the relative height between the mounting outer cylinder 1 and the desktop limiting ring 5 can be adjusted. When the socket inner cylinder 2 is raised to the highest position, the height from the top of the socket inner cylinder 2 to the desktop is 237 mm, and when the socket inner cylinder 2 is stored in the desktop, the distance from the top of the socket inner cylinder 2 to the desktop is about 76 mm, which provides sufficient space for the use of common chargers. After being raised, the jacks of the socket inner cylinder 2 are also arranged at a certain distance from the desktop, which reduces the possibility of liquid flowing into the interior of the socket on the desktop and improves the safety of the socket.

[0100] In one of the embodiments, the pneumatic lifting rod 6 is arranged at the middle position of the guide column 12, the telescopic end of the pneumatic lifting rod 6 is connected with the socket inner cylinder 2, and the lifting of the socket inner cylinder 2 can be driven through the telescoping of the pneumatic lifting rod 6.

[0101] In one of the embodiments, the strong current module 16 and the weak current module 17 are arranged in the socket inner cylinder 2. The jacks corresponding to the strong current module 16 are used to connect devices such as computers and table lamps, and the jacks corresponding to the weak current module 17 are used to connect devices such as mobile phones and tablets, which improves the use efficiency and limits the power consumption of each side to reduce the risk of overload. The plugs do not interfere with each other, and the overload protection 151 is arranged on the base to further improve the safety.

[0102] The embodiment is similar to the structures in the embodiments 1 to 3, and the difference is that, as shown inFigure 6 and Figure 7 As shown in the drawings, a waterproof sealing strip 8 is arranged at the edge of the bottom of the socket inner cylinder 2, which is tightly fitted between the outer side wall of the socket inner cylinder 2 and the inner side wall of the mounting outer cylinder 1. The upper water leakage hole 18 and the lower water leakage hole 19 are arranged through the side wall of the mounting outer cylinder 1. When the socket inner cylinder 2 is extended to the maximum position of the mounting outer cylinder 1, the upper water leakage hole 18 is just opposite to the position of the waterproof sealing strip 8. When the socket inner cylinder 2 is embedded in the mounting outer cylinder 1, the lower water leakage hole 19 is above the waterproof sealing strip 8.

[0103] In the embodiment, the upper water leakage hole 18 is arranged between the two adjacent inner cylinder limiting members 14, and one upper water leakage hole 18 is arranged between the two adjacent inner cylinder limiting members 14.

[0104] In the embodiment, the waterproof sealing strip 8 is arranged, which can effectively prevent water from flowing to the bottom of the mounting outer cylinder 1, so as to avoid damage of the electronic elements at the bottom of the mounting outer cylinder 1 after contacting water. In addition, in cooperation with the arrangement of the upper water leakage hole 18 and the lower water leakage hole 19, the accumulated water between the mounting outer cylinder 1 and the socket inner cylinder 2 can be better discharged. For example, when the socket inner cylinder 2 is in the state of being completely embedded in the mounting outer cylinder 1, if water flows into the gap between the socket inner cylinder 2 and the mounting outer cylinder 1, the water can be discharged from the lower water leakage hole 19, so as to prevent water from accumulating between the socket inner cylinder 2 and the mounting outer cylinder 1. When the socket inner cylinder 2 is pulled upward, the waterproof sealing strip 8 also moves upward, so as to clean the accumulated water on the inner side wall of the mounting outer cylinder 1 upward, and finally discharge the water from the upper water leakage hole 18. Therefore, the application has good waterproof effect, and can also clean the water on the inner side wall of the mounting outer cylinder 1, so that the inner side wall of the mounting outer cylinder 1 remains in a dry state. It should be noted that the blank waterproof area 221 is arranged below the outer side wall of the socket inner cylinder 2 in the application, the height of the blank waterproof area 221 is H, 2cm<H<5cm, and the blank waterproof area 221 is not provided with any jack. The blank waterproof area 221 can accumulate part of the water, so as to avoid water flowing into the jack.

[0105] In the application, only when the socket inner cylinder 2 is lifted to a specific preset point, the socket inner cylinder 2 remains in the state of being powered on, so as to completely eliminate the risk of electrification during the movement of the socket inner cylinder. Compared with the traditional technology which depends on the movement of the flexible wire with the socket inner cylinder 2 or adopts the mode of maintaining conduction by dynamic sliding contact, the application fixes the strong current module 16 on the socket inner cylinder 2, only the socket inner cylinder 2 moves during lifting, and only when the socket inner cylinder 2 is lifted to the highest point or lowered to the lowest point, the circuit is closed, so as to avoid line stretching and abrasion, physical deformation.

[0106] In addition, the traditional scheme has a complex structure, and the application focuses on fixing the strong current module 16 and the socket inner cylinder 2, arranging the strong current module 16 on the socket inner cylinder 2, controlling the power on-off of the socket inner cylinder 2 through the contact of the movable contact 21 and the fixed contact 11, realizing the on-off control through the pure trigger structure, without the need of a motor or a sensor, and through the layering of the positioning structure, the accurate alignment of the contact points is ensured, the structural complexity and the failure rate are reduced, the production, assembly and processing process is simple, the manufacturing cost is also reduced, and the practicability is improved.

[0107] The above-mentioned embodiments are only the preferred schemes of the application, and do not limit the application in any form, and other variants and modifications can be made without exceeding the technical scheme recorded in the claims.
