For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Please refer to Figures 1 to 4, the connection mechanism provided by the present invention is described below. The connection mechanism provided by the present invention includes a female component 10 and a male component 20, and the male component 20 can be docked with the female component 10. The female component 10 includes a first connector 12, a second connector 13, a first elastic component 14 and a first base 11, the second connector 13 can abut against the first connector 12, the first elastic component 14 is used to push the first connector 12 to abut against the second connector 13, the first connector 12 and the second connector 13 are installed on the first base 11, and the first connector 12 is movably connected to the first base 11. In this way, when the first elastic component 14 pushes the first connector 12 and the second connector 13 to abut, the first connector 12 and the second connector 13 can be connected, so as to realize the electrical connection between the first connector 12 and the second connector 13. The male component 20 includes a third connector 22, a fourth connector 23 and a second base 21, and the third connector 22 and the fourth connector 23 are installed on the second base 21. When the male component 20 is docked with the female component 10, the third connector 22 abuts against the first connector 12, and the third connector 22 pushes the first connector 12 to move, so that the first connector 12 is separated from the second connector 13, and the first connector 12 and the second connector 13 are disconnected; at the same time, the fourth connector 23 gradually moves toward the second connector 13, and finally abuts against the second connector 13, so that the fourth connector 23 and the second connector 13 are connected. The third connector 22 and the fourth connector 23 are spaced apart, so that the third connector 22 and the fourth connector 23 can be prevented from contacting. When the male component 20 is not docked with the female component 10, the first connector 12 and the second connector 13 on the female component 10 abut against each other to realize the conduction between the first connector 12 and the second connector 13; when the male component 20 is docked with the female component 10, the third connector 22 abuts against the first connector 12 to push the first connector 12 and the second connector 13 to separate, so that the first connector 12 and the second connector 13 are disconnected, and at the same time, the third connector 22 abuts against the first connector 12 and communicates, and the fourth connector 23 abuts against the second connector 13 and communicates. In this way, the connection mode of the first connector 12 and the second connector 13 is switched by docking the male component 20 with the female component 10, so that it can be used to switch and connect different circuits. In this way, the connection mode between different mechanisms is switched by docking or separation of the male component 20 and the female component 10, which is simple to operate, error-free, and avoids the safety hazards caused by cable connection.

[0027] Specifically, the first connector 12, the second connector 13, the third connector 22 and the fourth connector 23 are all conductors and are connected to the external circuit respectively; the first base 11 and the second base 21 are insulators. The external circuit is electrically connected to the first connector 12, the second connector 13, the third connector 22 and the fourth connector 23 respectively. Of course, the male component 20 and the female component 10 can be similar to the plug structure, set separately, and the male component 20 and the female component 10 are connected and fixed by snaps or other connectors; or they can be integrated in the end face of the external circuit device, and the male component 20 and the female component 10 are connected and fixed by the end faces of the two external circuit devices.

[0028] Please also refer to Figures 1 to 4 As a specific embodiment of the connection mechanism provided by the present invention, the second connection member 13 is fixed in the first base 11, and the second connection member 13 is provided with a first through hole for the third connection member 22 to pass through. The first connection member 12 and the third connection member 22 are respectively located at the two ends of the first through hole, and the third connection member 22 can pass through the first through hole, and then push the first connection member 12 at the other end of the first through hole, so that the first connection member 12 is separated from the second connection member 13. During the docking process between the male component 20 and the female component 10, the first through hole can play a role in positioning and guiding the third connection member 22 to push the first connection member 12, so that the third connection member 22 is smoothly connected to the first connection member 12, and the first connection member 12 is smoothly disconnected from the second connection member 13.

[0029] The third connector 22 and the fourth connector 23 can be fixed in the second base 21 or movably arranged in the second base 21, as long as it can be ensured that when the male component 20 and the female component 10 are docked, the third connector 22 can push the first connector 12 and the fourth connector 23 can abut against the second connector 13. Of course, the second connector 13 can also be movably installed in the first base 11, and the second connector 13 is pushed by the elastic member, so that when the fourth connector 23 moves toward the second connector 13, the elastic member can push the second connector 13 to elastically abut against the fourth connector 23.

[0030] Obviously, a first through hole can also be set on the first connecting member 12, and one end of the second connecting member 13 can be inserted into the first through hole, that is, the first connecting member 12 is sleeved outside the second connecting member 13; the third connecting member 22 is set outside the fourth connecting member 23, so that the male component 20 and the female component 10 cooperate with each other.

[0031] Specifically, the first connector 12 and the third connector 22 are in the shape of a rod, and the second connector 13 and the fourth connector 23 are in the shape of a tube; the first base 11 is provided with a first accommodating cavity for accommodating the first connector 12, the second connector 13 and the first elastic member 14, and the second base 21 is provided with a second accommodating cavity, and the third connector 22 and the fourth connector 23 are installed in the second accommodating cavity. The first accommodating cavity can provide a movable space for the first connector 12, and the second accommodating hole can provide a movable space for the third connector 22 and the fourth connector 23. Among them, the first connector 12 and the second connector 13 are displaced in the first accommodating cavity, and the third connector 22 and the fourth connector 23 extend out of the second accommodating cavity, so that the safety hazard caused by the first connector 12 and the second connector 13 being in the automatic conduction state can be avoided. When the male head component 20 and the female head component 10 are not docked, the first connector 12 and the second connector 13 are connected, but are located in the first accommodating cavity and are not easily contacted with the outside; although the third connector 22 and the fourth connector 23 extend out, they are not connected.

[0032] Furthermore, the first elastic member 14 is a first spring sleeved on the first connecting member 12, and the first connecting member 12 is provided with a step surface at one end close to the second connecting member 13, one end of the first spring abuts on the step surface, and the other end of the first spring abuts on the inner wall of the first base 11. In this way, the first connecting member 12 can move in a straight line to prevent the first connecting member 12 from getting stuck when moving.

[0033] Please also refer to Figure 2 and Figure 4 As a specific embodiment of the connection mechanism provided by the present invention, the fourth connection member 23 is movably connected to the second base 21, and the male component 20 further includes a second elastic member 24, which is used to push the fourth connection member 23 so that the fourth connection member 23 elastically abuts against the second connection member 13. During the docking process between the male component 20 and the female component 10, the first elastic member 14 pushes the first connection member 12 to abut against the third connection member 22, and the second elastic member 24 pushes the fourth connection member 23 to abut against the second connection member 13, which reduces the requirements for the position accuracy of the second connection member 13 and the fourth connection member 23, and can ensure that the fourth connection member 23 is tightly connected to the second connection member 13.

[0034] Please also refer to Figure 2 and Figure 4As a specific embodiment of the connection mechanism provided by the present invention, an insulating member 25 is sleeved on the third connection member 22, and the fourth connection member 23 is located outside the insulating member 25. In this way, the insulating member 25 can isolate the third connection member 22 and the fourth connection member 23, and prevent the third connection member 22 and the fourth connection member 23 from contacting and short-circuiting. Among them, the fourth connection member 23 can be fixed to the insulating member 25 or movably connected to the insulating member 25; the insulating member 25 can be fixed to the third connection member 22 or movably connected to the third connection member 22.

[0035] Specifically, the insulating member 25 is tubular, and one end of the third connecting member 22 close to the first connecting member 12 extends out of the insulating member 25. In this way, when the third connecting member 22 abuts against the first connecting member 12, the first connecting member 12 and the third connecting member 22 are connected.

[0036] More specifically, the end of the insulating member 25 away from the second connecting member 13 is provided with a flange 251 for stopping the fourth connecting member 23, and the third connecting member 22 is provided with a boss 221 for stopping the insulating member 25. In this way, when the third connecting member 22 moves toward the first connecting member 12, the relative movement between the fourth connecting member 23 and the third connecting member 22 can be avoided, resulting in failure of the insulating member 25, and the fourth connecting member 23 can be supported. On the other hand, when the fourth connecting member 23 encounters resistance, it can push the third connecting member 22 to move together, avoiding damage to the first elastic member 14.

[0037] Furthermore, one end of the second elastic member 24 abuts against the third connecting member 22, and the other end of the second elastic member 24 abuts against the inner wall of the second base 21. In this way, the second elastic member 24 can simultaneously push the third connecting member 22, the insulating member 25 and the fourth connecting member 23 to move, so that the fourth connecting member 23 abuts against the second connecting member 13. Among them, the elastic force of the second elastic member 24 is greater than the elastic force of the first elastic member 14. When the third connecting member 22 abuts against the first connecting member 12, the third connecting member 22 can smoothly push the first connecting member 12 and the second connecting member 13 to separate, and at the same time, the fourth connecting member 23 can be tightly abutted against the second connecting member 13. In this way, in a complex working environment, through the mutual cooperation of the first elastic member and the second elastic member, poor contact between the first connecting member 12 and the third connecting member 22 and between the second connecting member 13 and the fourth connecting member 23 caused by vibration in the environment can be avoided. Moreover, this ensures that when the external circuit device is switched, the first connector 12 and the second connector 22 are disconnected first, and then the second connector 13 and the fourth connector 23 are connected, which can protect the circuit.

[0038] Specifically, the second connecting member 13 is a second spring sleeved on the third connecting member 22. One end of the second spring abuts against the boss 221, and the other end of the second spring abuts against the inner wall of the second accommodating cavity. In this way, the third connecting member 22 can be guided to move by the second spring.

[0039] Preferably, the stroke of the fourth connector 23 in the second accommodating chamber is smaller than the stroke of the third connector 22 pushing the first connector 12 in the first accommodating chamber when the male component 20 and the female component 10 are docked. That is, when the fourth connector 23 is pushed to move, the maximum distance the fourth connector 23 moves is smaller than the maximum distance the third connector 22 pushes the first connector 12 to move. This prevents the fourth connector 23 from contacting the second connector 13 before the first connector 12 and the second connector 22 are separated when the male component 20 and the female component 10 are docked, thereby avoiding safety accidents. The stroke represents the maximum displacement of each connector in the corresponding accommodating chamber during telescopic movement.

[0040] Please also refer to Figure 2 and Figure 4 As a specific embodiment of the connection mechanism provided by the present invention, the end of the first connecting member 12 that abuts against the second connecting member 13 is tapered, the end of the fourth connecting member 23 close to the second connecting member 13 is tapered, and the inner wall of the first through hole has a first tapered surface and a second tapered surface, the first tapered surface cooperates with the end of the first connecting member 12, and the second tapered surface cooperates with the end of the fourth connecting member 23. The use of the first tapered surface and the second tapered surface can play a good positioning role, so that when the first connecting member 12 and the fourth connecting member 23 abut against the second connecting member 13, they can automatically align with the center of the first through hole; at the same time, the use of the first tapered surface and the second tapered surface can increase the contact area when the first connecting member 12 abuts against the second connecting member 13, and increase the contact area when the fourth connecting member 23 abuts against the second connecting member 13, so as to ensure the stability of the connection and reduce the resistance of the connection part. Moreover, the third connecting member 22 can be guided to abut against the first connecting member 12.

[0041] Please also refer to Figure 2 and Figure 4 As a specific embodiment of the connection mechanism provided by the present invention, the end of the third connection member 22 close to the first connection member 12 is tapered, and a tapered hole is provided at the end of the first connection member 12, and the end of the third connection member 22 matches the tapered hole. In this way, when the third connection member 22 moves toward the first connection member 12, it can automatically insert into the bottom of the tapered hole, increase the contact area between the third connection member 22 and the first connection member 12, and ensure the stability of the connection between the third connection member 22 and the first connection member 12.

[0042] Please also refer to Figure 2 and Figure 4 As a specific embodiment of the connection mechanism provided by the present invention, the first base 11 is provided with two first connectors 12, two second connectors 13, and two second elastic members 24, the two second connectors 13 are respectively matched with the two first connectors 12, and the two first elastic members 14 are respectively corresponding to the two first connectors 12; the second base 21 is provided with two third connectors 22 and two fourth connectors 23, the two third connectors 22 are respectively matched with the two first connectors 12, and the two fourth connectors 23 are respectively matched with the two second connectors 13. The two sets of switching structures are adopted, and the switching of two connection lines, such as the positive line, the negative line and the different voltage lines, can be realized at the same time, which is conducive to more convenient and quick switching.

[0043] Furthermore, the first base 11 includes a first front shell 111 and a first rear shell 112, and a first accommodating cavity is enclosed between the first front shell 111 and the first rear shell 112; the second base 21 includes a second front shell 211 and a second rear shell 212, and a second accommodating cavity is enclosed between the second front shell 211 and the second rear shell 212. The first front shell 111 and the first rear shell 112 can be directly fastened by means of snap connection, screw connection, etc., and the second front shell 211 and the second rear shell 212 can be directly fastened by means of snap connection, screw connection, etc., which are not further limited here.

[0044] Specifically, two stepped surfaces for stopping the fourth connector 23 and the flange 251 are provided in the second accommodating cavity, so that the stroke of the fourth connector 23 can be limited, and the third connector 22 and the insulating member 25 can be avoided. Preferably, the insulating member 25 is movably connected with the third connector 22 and the fourth connector 24, so that even if the first connector 12 is stuck, when the male component 20 and the female component 10 are connected, the third connector 22 can be retracted into the second accommodating cavity to avoid the first connector 12 and avoid damage to the female component 10. Among them, the stroke of the third connector 22 is greater than or equal to the stroke of the first connector 12, which provides sufficient space for avoiding the first connector 12.

[0045] Furthermore, a snap-on connection structure is provided between the first base 11 and the second base 21, so that when the male component 20 and the female component 10 are docked, it is easy to fix the male component 20 and the female component 10, making switching more convenient.

[0046] The present invention also provides a welding device, including a first welding mechanism, a second welding mechanism and the above-mentioned connecting mechanism, wherein the first welding mechanism includes a first housing 113, and the second welding mechanism includes a second housing 213 that can be matched with the first housing 113; the female head component 10 is installed on the first housing 113, and the male head component 20 is installed on the second housing 213. The connection between the first welding mechanism and the second welding mechanism can be achieved by docking the male head component 20 with the female head component 10, and the switching between the welding functions can be achieved, making the switching more convenient, faster and safer.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
