DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment, this embodiment provides a splicing socket, including a base 1 and a plurality of external sockets 2 that can be assembled on the base 1 to supply power to electrical equipment, the base 1 is externally connected to a plug 11, and the plug 11 is connected to a live wire and a neutral wire embedded in the base 1, such as Figure 1 As shown, mounting blocks are arranged at both ends of the base 1, and the mounting blocks are fixed to the frame at the foot of the bed by bolts, and the plug 11 is extended along the bottom of the bed to the head of the bed and plugged into the wall socket, and the base 1 is used as a power supply base. The live wire and the neutral wire in the base are connected to the plug through the extension wire.

[0025] In order to meet the power supply needs of multiple instruments and equipment at the same time, an assembly notch is opened on the base 1, and the external socket 2 can be detachably installed on the assembly notch. That is, according to the power supply demand, the same number of external sockets 2 are selected to be assembled on the assembly notch, and each external socket 2 is used to power one instrument and equipment.

[0026] Specifically, a plurality of docking holes are provided on the vertical side wall in the assembly notch, each docking hole comprises a live wire jack 12 and a neutral wire jack 13, a live wire plug 24 and a neutral wire plug are fixed to the rear side wall of the external socket 2, the live wire plug 24 is connected to the terminal 28 in one of the hollow support seats 23 through a wire, and the neutral wire plug is connected to the terminal 28 in the other hollow support seat 23 through a wire, such as Figure 2 and Figure 3 As shown, the external socket 2 utilizes the live wire plug 24 to be plugged into the live wire jack 12 , and the neutral wire plug to be plugged into the neutral wire jack 13 , so as to realize the power connection between the external socket 2 and the base 1 .

[0027] Two hollow support seats 23 are symmetrically arranged at the upper end of the external socket 2, and a flip shaft 21 is rotatably inserted between the two hollow support seats 23. Both axial ends of the flip shaft 21 are fixedly inserted with conductive posts 26 extending into the two hollow support seats 23 respectively. A terminal post 28 is fixed to the inner bottom wall of the hollow support seat 23, and a conductive post 27 is fixed to the upper end of the terminal post 28. One end of the conductive post 26 extending into the hollow support seat 23 is provided with a rotation groove that is rotatably fitted with the end of the conductive post 27. A support portion 25 is extended from the upper end of the side wall of the flip shaft 21, and a socket with a power socket is fixedly installed on the support portion 25. Board 22, conductive post II 27 is connected with a copper wire that passes through the support portion 25, the bottom wall of the socket board 22 and is connected to the built-in conductive sheet of the power socket, one of the terminals 28 is connected to the live wire plug 24 through the copper wire to realize line power supply, and the other terminal 28 is connected to the live wire plug 24 and one of the conductive posts I 26 through the copper wire to realize line power supply. As long as the rotating grooves of conductive post II 27 and conductive post I 26 are rotated and plugged together in real time, the line between the base 1 and the socket board 22 at the upper end of the external socket 2 can be energized through the conductive post II 27 and the conductive post I 26 as conductive media.

[0028] Specific usage method: install the base 1 on the frame at the end of the bed, use the plug 11 to connect the external power supply, and then set the required number of external sockets 2 according to the demand for the use of external power plugs and assemble them on the assembly gap to meet the power supply needs of multiple instruments at the same time and the power supply needs of instruments applied to the leg position at the end of the bed. In addition, the socket board 22 can rotate with the flip axis 21 as the flip center to change the direction of the power socket, meet the needs of plugging power plugs in different directions, and meet the needs of clinical use.

[0029] A snap-in track is provided on the bottom wall of the external socket 2, and a snap-in seat 14 located between the live wire jack 12 and the neutral wire jack 13 is fixed on the bottom wall inside the assembly notch. The snap-in track is pushed axially along the snap-in seat 14, and the live wire plug 24 is inserted into the live wire jack 12 and the neutral wire plug is inserted into the neutral wire jack 13 at the same time. On the one hand, rapid assembly between the external socket 2 and the base 1 is achieved, and at the same time, it can ensure that the live wire plug 24 and the neutral wire plug can be quickly aligned with the live wire jack 12 and the neutral wire jack 13 respectively for insertion, thereby improving assembly efficiency.

[0030] Further, such as Figure 4 and Figure 5 As shown, a T-shaped lifting groove is provided on the top wall of the live wire jack 12, and a T-shaped conductive block 15 is slidably inserted in the T-shaped lifting groove. A T-shaped wiring block 16 is fixed on the upper end of the T-shaped conductive block 15, and the T-shaped wiring block 16 is connected to the live wire through a wire. A side wall of the bottom end of the T-shaped conductive block 15 facing the opening of the live wire jack 12 is provided with an inclined surface, and the inclined surface is inclined downwardly toward the side away from the opening of the live wire jack 12; when the live wire plug 24 is inserted into the live wire jack 12, the end of the live wire plug 24 contacts the inclined surface of the T-shaped conductive block 15. As the live wire plug 24 is continuously inserted deeper, the inclined surface and the end of the live wire plug 24 can slide relative to each other, that is, the T-shaped conductive block 15 slides upward along the T-shaped lifting groove. When the end of the live wire plug 24 passes over the bottom wall of the T-shaped conductive block 15 and continues to be inserted deep into the live wire jack 12, the T-shaped conductive block 15 no longer slides upward, and the bottom wall of the T-shaped conductive block 15 is in sliding contact with the outer wall of the live wire plug 24, so that the live wire line is connected.

[0031] At the same time, a recessed groove is provided in the inner bottom wall of the neutral line jack 13, and a conductive ring 18 of an annular structure is fixed in the inner bottom wall of the recessed groove. The upper side wall of the conductive ring 18 extends out of the recessed groove and enters the neutral line jack 13, and the bottom wall of the conductive ring is connected to the neutral line through a wire. When the neutral line plug is inserted into the neutral line jack 13, the end of the neutral line plug will contact the conductive ring 18. As the neutral line plug is continuously inserted deeper, the conductive ring 18 will be compressed into the recessed groove, and the conductive ring 18 will generate rebound potential energy against the bottom wall of the neutral line plug, so that the neutral line is connected.

[0032] In summary, when both the live wire and the neutral wire are connected, the circuit between the socket plate 22 at the upper end of the external socket 2 and the base 1 is guaranteed to be connected. As long as the power plug of the medical instrument is inserted into the power socket of the socket plate 22, power supply can be achieved.

[0033] In addition, an arc-shaped spring piece 17 is fixed to the inner side wall of the T-shaped lifting groove and is pressed against the upper side of the T-shaped conductive block 15 in real time. The elastic force of the arc-shaped spring piece 17 is used to force the T-shaped conductive block 15 to slide down along the T-shaped lifting groove in real time, so as to ensure that the bottom end of the T-shaped conductive block 15 can fit against the outer wall of the live wire plug 24 in real time.

[0034] At the same time, the bottom end of the T-shaped conductive block 15 is an arc-shaped structure and matches the radial outer wall of the live wire plug 24, so as to ensure that the side wall of the bottom end of the T-shaped conductive block 15 and the outer wall of the live wire plug 24 are in surface contact instead of line contact, thereby ensuring the stability of the line connection.

[0035] The base 1 , the clamping seat 14 , the flip shaft 21 , the socket plate 22 , and the hollow support seat 23 are all made of insulating plastic.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
