Description

Technical Field

[0001] The utility model relates to the technical field of water hose joints, in particular to a joint assembly. Background Art

[0002] The connector assembly is a common component in the pipe network. The existing connector assembly usually includes a first connector for connecting the conveying component (such as a water hose, etc.) and a second connector adapted to the first connector, wherein the first connector can be an existing male connector or female connector, and the second connector can be a female connector or male connector adapted to the first connector. The second connector can also be a water distributor (the water distributor is equipped with a female connector or a male connector) or a water collector (the water collector is equipped with a female connector or a male connector) or a water gun (such as a fire water gun, which is equipped with a female connector or a male connector) adapted to the first connector. The water distributor is mainly used to connect the water supply trunk line with multiple water outlet branches to play a role of diversion; the water collector is mainly used to connect multiple water supply branches with the water supply trunk line to play a role of confluence; the water gun is usually installed at the end of the pipe network and is a water-spraying tool for fire extinguishing. The connector assembly is not only widely used in daily life and industrial production, but also a widely used instrument in the field of firefighting.

[0003] With the advancement of technology and the change of market demand, some joint components are equipped with electrical devices, and some conveying components adapted to the joint components are also equipped with electrical devices (such as electroluminescent wires). When in use, it is necessary to configure corresponding power supplies for these electrical devices so that the power supply can be used to power each electrical device. The power supply is usually a power supply device arranged in the joint component. The electrical devices usually include light-emitting devices used to play a marking or indicating effect on site. For example, the light-emitting device can be an electroluminescent wire, a lamp bead, etc. arranged on the conveying component, or a light belt, a lamp bead, a display screen, etc. arranged on the joint component. In addition, in some schemes, the electrical devices also include a control module arranged in the power supply device. For example, some existing fire-fighting joints (male or female joints) are equipped with a power supply device for power supply. At the same time, the fire-fighting joint itself may be equipped with light-emitting devices such as lamp beads and display screens. The water hose (a conveying component) adapted to the fire-fighting joint may also be equipped with light-emitting devices such as electroluminescent wires and lamp beads. During assembly, the water hose is connected to the fire-fighting joint, and at the same time, the power supply device is electrically connected to each light-emitting device so as to power each light-emitting device.

[0004] In order to simplify the operation and improve the efficiency of laying the pipeline network during use, a technology was developed in the early stage that allows the power supply device to automatically supply power to the light-emitting device during the operation of the fire-fighting pipeline network. Specifically, a detection component is configured in the power supply device, and the detection component is used to detect whether there is a conductive medium in the pipeline network. When a conductive medium (such as water, solution, etc.) is detected, it indicates that the pipeline network has started the transportation operation, thereby automatically controlling the internal power supply module to supply power to the light-emitting device to light up the light-emitting device, especially to light up the electroluminescent wires or lamp beads in the water hose, so that the water hose glows, so as to play the role of line guidance on the scene, which is more conducive to rapid rescue and escape on the scene. However, in actual application, it is found that this design can only power the light-emitting device when the pipeline network starts to transport. Although it can achieve the effect of automatic power supply and automatic lighting, before the pipeline network starts to transport, the light-emitting devices in the pipeline (or pipeline network) are not working and are in an off state, and cannot play the role of identification or line guidance on site. On the one hand, the lighting time of the light-emitting device is very delayed, which is not conducive to the role of identification or line guidance on site at the first time of pipeline network laying. It is not only not conducive to improving rescue efficiency, but also has safety hazards; on the other hand, due to the great differences in the conductive properties of the medium transported by the pipeline network, this design is unstable and has poor reliability. Therefore, how to build line guidance on site earlier and more efficiently and how to improve the reliability of line guidance need to be solved urgently. Summary of the invention

[0005] The utility model aims to solve the problem of building a route guide on site earlier and more efficiently and further improving the reliability of the route guide, and provides a connector assembly that is more convenient to use. It can not only build a route guide for rescue escape on site earlier and more efficiently, but also greatly improve the stability and reliability of the route guide. The main concept is:

[0006] A joint assembly comprises a first joint and a second joint, wherein the first joint comprises an internal flow channel and a first connecting end, the second joint comprises an internal flow channel and a second connecting end adapted to the first connecting end, the first joint and the second joint are connected to each other through the cooperation of the first connecting end and the second connecting end,

[0007] The first connector is also provided with a power supply device and a switch for supplying power to the electrical device, the switch is connected to the power supply device, and the switch is arranged at a position adapted to the second connection end; when the second connection end is connected to the first connection end, the switch is closed under the squeezing action of the second connection end, and the power supply device supplies power to the light-emitting device after the switch is closed. In this scheme, by configuring the mutually adapted first connector and the second connector, the first connector and the second connector can be connected or disconnected with each other through the mutually adapted first connection end and the second connection end, so as to meet the requirements of rapid laying of pipe network and rapid disassembly; by configuring the power supply device for supplying power to the electrical device at the first connector, the power supply device can be used to supply power to the adjacent light-emitting devices such as electric light wires and lamp beads, so as to use the light-emitting devices to play the role of identification, line guidance, etc. on the scene, so as to facilitate rapid rescue and escape on the scene. By configuring the switch, the switch is connected to the power supply device, and the switch is used to control whether the power supply device supplies power to the light-emitting device connected thereto, so as to achieve the purpose of effectively controlling the lighting or extinguishing of the light-emitting device, so as to light up the light-emitting device when needed and extinguish the light-emitting device when not needed, so as to achieve the purpose of energy saving. By setting the switch at a position that adapts to the second connecting end, and making the second connecting end and the switch form an on / off match, during the process of laying the pipeline network on site, when the second connector is connected to the first connector, the switch can be closed under the squeezing action of the second connecting end, so that the power supply device connected to the switch can automatically supply power to the light-emitting device connected thereto, so as to achieve the effect of automatically lighting up the light-emitting device in the pipeline, so that while laying the pipeline, a mark or line guide composed of light-emitting devices can be synchronously built on site. With such a design, on the one hand, each light-emitting device can be lit on site without any additional operations, which not only makes it more convenient to use, but also saves time and effort. It is convenient, and can build signs or line guides on site more quickly and efficiently; secondly, the light-emitting devices can be lit synchronously on site while the pipeline is being laid, so that the lighting time of the light-emitting devices is very early, which can not only play the role of line guidance on site earlier, but also help to improve rescue efficiency and eliminate safety hazards; thirdly, the state of each light-emitting device in the pipeline has nothing to do with whether the pipeline starts the transportation operation, and the luminous effect of each light-emitting device in the pipeline has nothing to do with the conductive properties of the transported medium, so that the state and effect of the light-emitting device are not affected by external factors, which can greatly improve the stability and reliability of the line guidance.

[0008] In order to solve the problem of more convenient use, the switch further adopts a switch with a rebound function. When the second connection end is separated from the first connection end, the switch is automatically disconnected. When the pipeline is removed, as long as the second connection end is separated from the first connection end, the switch can automatically rebound and reset under the action of its own elastic force, thereby automatically disconnecting, so that the power supply device no longer supplies power to the light-emitting device, so that the light-emitting device can be automatically extinguished, which is not only more convenient to use, but also more energy-saving.

[0009] Preferably, the switch is a micro switch or a waterproof travel switch.

[0010] Preferably, the first connecting end includes a connecting cavity adapted to the second connecting end, the connecting cavity is connected to the internal flow channel of the first joint, a limiting portion is formed between the connecting cavity and the internal flow channel, and a side of the limiting portion facing the connecting cavity is a limiting end surface;

[0011] A first connection part is configured in the connection cavity, and a second connection part adapted to the first connection part is configured on the outer side of the second connection end, and the first connection end and the second connection end are detachably connected through the cooperation between the first connection part and the second connection part;

[0012] When the second connection terminal is connected to the first connection terminal, the second connection terminal is inserted into the connection cavity, and the end of the second connection terminal corresponds to the limiting end face. In this solution, by configuring the connection cavity, the first connection part is configured inside the connection cavity, and the second connection part adapted to the first connection part is configured on the outer side of the second connection terminal, so that the first connection terminal and the second connection terminal can be detachably connected in the connection cavity through the cooperation of the first connection part and the second connection part, which not only makes the connection between the first connector and the second connector more reliable and less prone to water leakage, but also the end of the second connection terminal corresponds to the limiting end face, so that the switch has more layout positions and can be flexibly arranged according to needs.

[0013] In order to facilitate the switch to form a switch match with the second connection terminal, preferably, the switch is arranged on the inner wall of the connection cavity and protrudes from the inner surface of the connection cavity. This not only facilitates the setting and assembly of the switch, but also facilitates the switch to form a switch match with the second connection terminal, without interfering with the connection effect of the first connector and the second connector.

[0014] In order to solve the problem of improving the stability and reliability of the switch and the second connection terminal, the limit part is further configured with an assembly cavity, the switch is installed in the assembly cavity, the switch protrudes from the limit end face, and the switch corresponds to the end of the second connection terminal. By configuring the assembly cavity, it is easier to install and seal the switch; by installing the switch on the limit part, and making the switch protrude from the limit end face, and the switch corresponds to the end of the second connection terminal, not only can the switch and the second connection terminal form a switch match without interference, but also can ensure that the switch can be closed by the second connection terminal, which can improve the stability and reliability of this design.

[0015] In order to solve the problem of preventing water leakage, preferably, a sealing gasket is also provided at the bottom of the assembly cavity.

[0016] To solve the problem of easy assembly, further, the first connector is also configured with a wire hole connected to the assembly cavity, so that a wire can be arranged through the wire hole, so that the switch can be connected to the power supply device.

[0017] For the detachable connection between the first connector and the second connector, preferably, the first connector is a spring sheet arranged along the circumferential direction of the connecting cavity, and the second connector is a positioning ring constructed on the outer side of the second connecting end, and the outer diameter of the positioning ring is larger than the inner diameter of the internal flow channel in the first connector, so that the detachable connection between the first connector and the second connector is achieved through the cooperation between the positioning ring and the spring sheet.

[0018] In order to solve the problem of using a switch to control whether the power supply device supplies power to the light-emitting device, in some preferred solutions, the power supply device includes a power module for storing electric energy and a power supply circuit for at least outputting electric energy to the light-emitting device, and the switch is connected in series to the power supply circuit, so as to use the switch to control the on and off of the power supply circuit, thereby achieving the purpose of directly controlling whether the light-emitting device obtains electric energy.

[0019] In order to solve the problem of using a switch to control whether the power supply device supplies power to the light-emitting device, in some preferred solutions, the power supply device includes a control module and a power module for storing electric energy, the control module is connected to the power module, the switch is connected to the control module, and the control module controls whether the power module supplies power to the light-emitting device according to the state of the switch. In this solution, when the second connection terminal is connected to the first connection terminal, the switch is closed under the squeezing action of the second connection terminal, and a signal is generated, and the signal is transmitted to the control module, so that the control module can control the power module to supply power to the light-emitting device according to the signal, thereby achieving the purpose of automatically lighting the light-emitting device. With such a design, it is only necessary to connect the second connection terminal to the first connection terminal. After the control module receives the signal of the switch closure, it can automatically supply power to the light-emitting device according to the preset strategy. Not only does it not require additional operation to light up the light-emitting device at the first time, it is more convenient to use, and can significantly improve efficiency. Moreover, it does not need to rely on the transmission medium, nor is it affected by the transmission medium, so that the power supply device can supply power to the outside earlier to meet the needs under any working conditions.

[0020] Preferably, the power supply device further comprises a receiving space, at least the power module is arranged in the receiving space; the receiving space is constructed at the first joint, or the receiving space is constructed at the shell, and the shell is installed at the first joint, so as to install and protect the power module.

[0021] Furthermore, the power supply device also includes a charging connector, which is connected to the power module so as to supply power to the power module through the charging connector.

[0022] Furthermore, the power supply device also includes a power supply connector, and the power supply connector is connected to the power supply circuit.

[0023] To facilitate the connection of the conveying component, further, the first joint also includes a water hose connector for connecting the conveying component.

[0024] To improve versatility, preferably, the second connector is a male connector or a female connector or a water distributor or a water collector or a water gun adapted to the first connector.

[0025] A connector comprises an internal flow channel, a first connection end for connecting to a second connection end, a power supply device for supplying power, and a switch, wherein:

[0026] The switch is connected to the power supply device, and is arranged at a position adapted to the second connection terminal, and is used to be closed under the squeezing action of the second connection terminal;

[0027] The power supply device includes a power module, and the power module supplies power to the light-emitting device connected thereto when the switch is closed. When in use, when the connector is connected to a second connector adapted thereto, the switch can be closed under the squeezing action of the second connection end of the second connector, so that the power module can automatically supply power to the light-emitting device connected thereto, achieving the effect that the light-emitting device is automatically lit when the connector is connected.

DETAILED DESCRIPTION

[0040] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0041] Example 1

[0042] This embodiment provides a connector assembly, including a first connector 1 and a second connector 2 adapted to the first connector 1, wherein:

[0043] like Figure 1-Figure 3As shown, the first joint 1 includes an internal flow channel 12, a first connection end 11 and a hose connector 13, wherein the internal flow channel 12 runs through both ends of the first joint 1, the first connection end 11 and the hose connector 13 are respectively located at both ends of the first joint 1, the first connection end 11 is mainly used to connect the second joint 2 adapted to the first joint 1, and the hose connector 13 is mainly used to connect the conveying component 6, and the conveying component 6 can be a water pipe, a water hose, etc. In this embodiment, the conveying component 6 preferably adopts a luminous water hose, such as a luminous fire hose.

[0044] like Figure 5 and Figure 6 As shown, the second joint 2 includes an internal flow channel 12, a second connection end 21 adapted to the first connection end 11, and a water hose connector 13. Similarly, the internal flow channel 12 runs through both ends of the second joint 2, the second connection end 21 and the water hose connector 13 are respectively located at both ends of the second joint 2, the second connection end 21 is mainly used to connect the first joint 1 adapted to the second joint 2, and the water hose connector 13 is mainly used to connect the conveying component 6, which can be a water pipe, a water hose, etc.

[0045] During assembly, the first connector 1 and the second connector 2 can be connected together through the cooperation of the first connection terminal 11 and the second connection terminal 21, and the first connector 1 and the second connector 2 can be connected to each other to achieve the conveying function. In this embodiment, since the first connector 1 is adapted to the second connector 2, during implementation, when the first connector 1 is a male connector, the second connector 2 can be a female connector adapted thereto; when the first connector 1 is a female connector, the second connector 2 can be a male connector adapted thereto.

[0046] In order to facilitate the connection between the first connector 1 and the second connector 2, during implementation, the first connecting end 11 may include a connecting cavity 14 adapted to the second connecting end 21, such as Figure 1 and Figure 3 As shown, the connecting cavity 14 is connected to the internal flow channel 12 of the first joint 1, and the inner diameter of the connecting cavity 14 can be larger than the inner diameter of the internal flow channel 12, so that a limiting portion 15 can be formed between the connecting cavity 14 and the internal flow channel 12. Figure 1 and Figure 3 As shown, during connection, the second connection terminal 21 can be inserted into the connection cavity 14, and the end of the second connection terminal 21 corresponds to the limiting portion 15, as shown in FIG. Figure 3 and Figure 7 As shown, therefore, the surface of the limiting portion 15 corresponding to the second connecting terminal 21 can be called a limiting end surface 151. Figure 3 and Figure 7 As shown, that is, the limiting end surface 151 in the limiting portion 15 is facing the second connecting terminal 21 so as to match with the second connecting terminal 21 .

[0047] Of course, in a more perfect embodiment, the first connecting terminal 11 further includes a first connecting portion constructed in the connecting cavity 14, such as Figure 1 As shown, at the same time, the outer side surface of the second connecting terminal 21 is constructed with a second connecting portion adapted to the first connecting portion. During assembly or fitting, the first connecting terminal 11 and the second connecting terminal 21 can be detachably connected through the cooperation of the first connecting portion and the second connecting portion. During implementation, the first connecting portion and the second connecting portion respectively have a variety of matching implementation methods. For example, in one implementation, the first connecting portion can be an internal thread constructed on the inner wall of the connecting cavity 14, and correspondingly, the second connecting portion can be an external thread constructed on the outer side surface of the second connecting terminal 21. The internal thread is adapted to the external thread, so that the first connector 1 and the second connector 2 can be threadedly connected. For example, in another implementation, the first connecting portion can be a spring sheet 16 arranged along the circumferential direction of the connecting cavity 14, such as Figure 1 and Figure 3 As shown, the spring piece 16 can elastically move along the radial direction of the connecting cavity 14. Accordingly, the second connecting portion can be a positioning ring 22 constructed on the outer side of the second connecting end 21. Figure 5 As shown, during assembly, the second connection end 21 of the second connector 2 is inserted into the connection cavity 14, and the positioning ring 22 squeezes the spring sheet 16 to deform. When the positioning ring 22 passes through the spring sheet 16, the spring sheet 16 automatically returns to its initial position, thereby locking the positioning ring 22. Figure 7 As shown, the second connector 2 is prevented from falling off, so that the first connector 1 and the second connector 2 are firmly connected together. It can be understood that the first connector and the second connector of this structure are relatively common in connectors. For example, the KDK65 type card-type fire protection interface adopts the first connector and the second connector of this structure, which will not be described here. However, no matter what structure of the first connector and the second connector is adopted, when the first connector 1 and the second connector 2 are connected together through the cooperation of the first connector and the second connector, the end of the second connection terminal 21 is usually corresponding to the limiting end face 151 of the limiting portion 15, as shown in FIG. Figure 7 As shown, the outer side surface of the second connection end 21 usually corresponds to the inner wall surface of the connection cavity 14. When the first joint 1 is connected to the second joint 2, the internal flow channel 12 of the first joint 1 and the internal flow channel 12 of the second joint 2 are connected to each other. Figure 7 As shown, in order to achieve the conveying function.

[0048] As an example, in this embodiment, the first connector 1 can be a female connector of a KDK65 type card-type fire protection interface, and the second connector 2 can be a male connector of a KDK65 type card-type fire protection interface, such as Figure 5 and Figure 6 As shown, the slip ring for unlocking is not shown in the figure.

[0049] In this embodiment, the first connector 1 is further provided with a power supply device 3, such as Figure 2 and Figure 7 As shown, the power supply device 3 is mainly used to supply power to electrical devices (including light-emitting devices 61, such as the electric light-emitting wire in the water hose, the light or screen configured on the first connector 1, and other light-emitting devices 61). In implementation, the power supply device 3 includes a power module 32 for storing electrical energy, and the power module 32 is configured with one or more batteries, and the battery can preferably be a rechargeable battery for repeated use. When the power module 32 is configured with a rechargeable battery, the power supply device 3 also includes a charging interface 33, which is connected to the power module 32 so that the power module 32 can be charged through the reserved charging interface 33.

[0050] In order to facilitate external power supply, at this time, the power supply device 3 also includes a power supply circuit (or power supply wire) for at least transmitting electric energy to the light-emitting device 61, and the power supply circuit is connected to the power module 32. When in use, the light-emitting device 61 is connected to the power supply circuit interface. Of course, in a more perfect embodiment, the power supply device 3 also includes a power supply connector 34, and the power supply connector 34 is connected to the power supply circuit. When in use, the light-emitting device 61 only needs to be connected to the power supply connector 34, which is very convenient.

[0051] In implementation, the power supply device 3 has multiple implementations. For example, in one implementation, the power supply device 3 can be integrated in the first connector 1; for example, a receiving space 31 for installing the power supply device 3 can be directly constructed in the first connector 1, such as Figure 2 As shown, the power supply device 3 can be installed in the accommodation space 31. In this case, the charging interface 33 and the power supply connector 34 can be arranged on the outer surface of the first connector 1. For another example, in another embodiment, the power supply device 3 can also include a shell, which encloses a relatively closed accommodation space 31, and the power module 32 and the like are installed in the accommodation space 31. The charging interface 33 and the power supply connector 34 can be arranged in the shell. In this case, the power supply device 3 is an independent device relative to the first connector 1. When in use, the shell of the power supply device 3 can be fixed to the first connector 1, so that the power supply device 3 can be used to power the light-emitting wire in the water hose, the light or screen and other light-emitting devices 61 configured on the first connector 1.

[0052] In this embodiment, the first connection terminal 11 is also provided with a switch 4. Figure 1 and Figure 3As shown, the switch 4 is connected to the power supply device 3, and the switch 4 is arranged at a position adapted to the second connection terminal 21, so that when the second connection terminal 21 is connected to the first connection terminal 11, the switch 4 can be closed under the squeezing action of the second connection terminal 21. In this embodiment, the switch 4 can be arranged in series with the power supply circuit, so as to use the switch 4 to control whether the power supply device 3 supplies power to the outside; the switch 4 can also be connected to a relay, which is arranged in the power supply circuit, and the relay is used to control the on and off of the power supply circuit.

[0053] In this embodiment, the switch 4 can be a physical entity switch 4 with a rebound function in the prior art. In implementation, the switch 4 can preferably be a micro switch 4, or a waterproof travel switch 4, etc. In implementation, the switch 4 has a variety of setting positions. For example, in one embodiment, the switch 4 can be set at the end of the first connection terminal 11, and a trigger structure adapted to the switch 4 is constructed on the second connector 2. When the second connection terminal 21 is connected to the first connection terminal 11, the trigger structure just squeezes the switch 4 and closes the switch 4, so that the power supply circuit is changed from an open circuit state to a closed circuit state, so that the power module 32 can smoothly supply power to the outside through the power supply circuit.

[0054] For example, in another preferred embodiment, the switch 4 can also be arranged in the connection cavity 14 of the first connection terminal 11, so that the switch 4 can be squeezed by the second connection terminal 21 inserted into the first connection terminal 11. In implementation, the switch 4 can be arranged on the inner wall (including the side wall and the limit portion 15) of the connection cavity 14, so that it can be closed under the squeezing effect of the outer wall of the second connection terminal 21. In a preferred embodiment, the switch 4 can be preferentially arranged on the limit portion 15, such as Figure 1 and Figure 3 As shown, so as to correspond to the end of the second connection terminal 21, it does not affect the matching between the first connection terminal 11 and the second connection terminal 21, and can ensure that the switch 4 can be closed.

[0055] Since the switch 4 is mounted on the first connection terminal 11, in order to facilitate the second connection terminal 21 to contact and close the switch 4 more stably and reliably, in a further embodiment, the switch 4 can protrude from the inner surface of the connection cavity 14 in the first connection terminal 11 (including the limiting end surface 151 of the limiting portion 15 and the inner surface of the side wall), so as to better adapt to the second connection terminal 21 and close under the squeezing action of the second connection terminal 21. For example, Figure 1 and Figure 3 As shown, the switch 4 is disposed on the limiting portion 15 and protrudes outward from the limiting end surface 151 so as to contact the end of the second connecting terminal 21 more smoothly and reliably.

[0056] In order to facilitate the installation of the switch 4, during implementation, the first connector 1 is further configured with an assembly cavity 51 for installing the switch 4. The switch 4 is installed in the assembly cavity 51, so that the switch 4 is more stable. Figure 3 and Figure 4 As shown, a sealing gasket 53 is also provided at the bottom of the assembly cavity 51, and the switch 4 is installed above the sealing gasket 53 so that the sealing gasket 53 can be used to seal and prevent water leakage. Figure 3 and Figure 4 As shown, the limiting portion 15 is constructed with an assembly cavity 51 and a wire hole 52 for arranging the wire 54. The assembly cavity 51 is connected to the wire hole 52. The assembly cavity 51 passes through the limiting end surface 151 of the limiting portion 15, and the wire hole 52 passes through the other end surface of the limiting portion 15. Figure 3 and Figure 4 As shown, the switch 4 can be fixed in the assembly cavity 51 by interference fit or by adhesive. A sealing gasket 53 is provided at the bottom of the assembly cavity 51. The switch 4 protrudes outward from the limiting end surface 151. Figure 3 and Figure 4 Of course, in practice, the switch 4 can also be threadedly connected to the first joint 1, and the switch 4 can also be fixed to the first joint 1 by fasteners such as bolts or screws, so as to facilitate installation, removal and replacement of the switch 4.

[0057] In a further embodiment, the power supply device 3 may also include a control module, which may be arranged in the accommodating space 31, and the control module is connected to the power module 32 so as to supply power to the control module. At this time, the switch 4 may also be connected in series in the power supply circuit of the power module 32 to the control module, so that when the first connector 1 and the second connector 2 are not connected, the switch 4 is in an off state, and the power module 32 does not supply power to the outside. When the first connector 1 and the second connector 2 are connected, the switch 4 is automatically closed, so that the power module 32 can automatically supply power to the control module and the light-emitting device 61. When the first connector 1 and the second connector 2 are separated from each other, the switch 4 is automatically disconnected, so that the power module 32 can automatically stop supplying power to the control module and the light-emitting device 61, which is very convenient and efficient.

[0058] It can be understood that, during implementation, the control module may include an existing controller or control circuit (such as a circuit board), etc., which will not be described in detail here.

[0059] It can be understood that in this embodiment, the second connector 2 can be a male connector or a female connector adapted to the first connector 1, or it can be a water distributor, a water collector, a water gun (fire hose), etc. adapted to the first connector 1. As long as the second connector 2 is connected to the first connector 1, the power module 32 on the first connector 1 automatically supplies power to the outside. As long as the second connector 2 is disconnected from the first connector 1, the power module 32 on the first connector 1 automatically stops supplying power to the outside.

[0060] It can be understood that, during implementation, the first connector 1 can be configured with one, two or more switches 4. When at least two switches 4 are configured, the switches 4 can be evenly arranged along the circumferential direction of the connecting cavity 14, and the switches 4 are connected in parallel with each other to improve reliability during use and ensure that a switch 4 is closed when the first connector 1 is connected to the second connector 2.

[0061] Example 2

[0062] The main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that in the connector assembly provided in the present embodiment, the connection relationship of the switch 4 in the power supply module is different. Specifically, in the present embodiment, the power supply device 3 includes not only a power supply module 32 for storing electric energy, but also a control module, which is connected to the power supply module 32. At the same time, in the present embodiment, the switch 4 is connected to the control module, and the switch 4 is used to detect whether the first connector 1 and the second connector 2 are connected. The control module controls whether the power supply module 32 supplies power to the light-emitting device 61 according to the state of the switch 4. In the present embodiment, when the switch 4 is closed, the control module changes the power supply circuit from the disconnected state to the connected state, so that the power supply circuit is unblocked, so that the control power supply module 32 can supply power to the light-emitting device 61 through the power supply circuit. When the switch 4 is disconnected, the control module changes the power supply circuit from the connected state to the disconnected state, and the control module controls the power supply module 32 to stop supplying power to the light-emitting device 61. More specifically, as an example, a controllable switch structure is configured in the power supply circuit, and the controllable switch structure is connected to the control module. When the control module receives a signal from the switch 4, the control module controls the controllable switch structure so that the power supply circuit changes from the disconnected state to the connected state.

[0063] Specifically, in this embodiment, when the first connector 1 is connected to the second connector 2, the switch 4 is closed under the squeezing action of the second connection terminal 21, and a signal is generated, and the signal is transmitted to the control module. After the control module receives the signal, the control module can automatically control the power module 32 to supply power to the light-emitting device 61, thereby achieving the purpose of automatically controlling the start of the light-emitting device 61. In actual use, it is only necessary to connect the second connection terminal 21 to the first connection terminal 11, and the control module can automatically supply power to the light-emitting device 61 according to a preset strategy, which not only does not require additional operations, but is more convenient to use and can significantly improve efficiency. Moreover, the automatic process does not need to rely on the conveying medium and is not affected by the conveying medium, so that the power supply device 3 can supply power to the outside earlier, which can meet the use requirements of more working conditions and occasions.

[0064] Example 3

[0065] The present embodiment provides a conveying system, including a conveying pipeline, wherein the conveying pipeline includes a conveying component 6 and the joint assembly, wherein one end of the conveying component 6 is connected to a water hose connector 13 of a first joint 1, such as Figure 8 As shown, the conveying component 6 can be connected to the first joint 1, and the conveying component 6 can be a water belt or a water pipe, etc., so as to play the function of conveying.

[0066] In a more complete solution, the conveying system further comprises a light emitting device 61 arranged on the conveying component 6 and / or the first joint 1, for example Figure 8 As shown, the light emitting device 61 can be an electroluminescent wire, a lamp bead, a display screen arranged on the conveying component 6, or a lamp bead, a display screen, etc. arranged on the first joint 1. The light emitting device 61 is connected to the power supply device 3 (specifically, connected to the power supply circuit of the power supply device 3, such as connected to the power supply joint 34) to obtain power from the power supply device 3. When laying the pipeline on site, when the second joint 2 is connected to the first joint 1, the switch 4 in the first joint 1 is closed, and the photoelectric device can automatically supply power to the light emitting device 61 and other electrical devices, so that the light emitting device 61 can automatically emit light (light up), so that it can play the role of identification or line guidance on site, and the operation is very simple, convenient and efficient.

[0067] Of course, in a more complete solution, the system also includes a delivery power, which can preferably use a delivery pump. The delivery power is connected to the delivery component 6 to provide the power required for delivering the medium (such as water, solution, foam, etc.).

[0068] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
