[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0041] like Figures 1 to 2 FIG. 1 is a structural diagram of a mechanical interlock contactor provided by an embodiment of the present invention, comprising:

[0042] The contactor body 1 has two contactor bodies 1 and further comprises:

[0043] A fixed locking block 2, which is connected to the skirts of the shells of the two contactor bodies 1 and is used to connect the two contactor bodies 1;

[0044] The interlocking member 3 cooperates with the T-slot 14 provided on the side wall of the contactor body 1. The interlocking member 3 is laterally installed into the contactor body 1 through the T-slot 14. When the contactor body 1 is closed, the interlocking member 3 drives the other contactor body 1 to lock.

[0045] In one embodiment of the present invention, the mechanical interlock contactor is provided with an interlocking member 3 to address the problems in the prior art that the interlocking members can only be installed after the top cover of the contactor is removed, the assembly is cumbersome and difficult to remove, and the two contactors are mostly connected by a mortise and tenon structure, which cannot be removed after assembly. The interlocking member 3 cooperates with the T-slot 14 on the side wall of the contactor body 1. The interlocking member 3 can be directly assembled and disassembled from the side of the contactor body 1 in an external manner without removing the contactor body 1, which greatly improves the convenience of installing and disassembling the interlocking member 3. At the same time, a fixed locking block 2 is provided to be installed on the skirt of the shell of the two contactor bodies 1, specifically installed at the connection between the upper base and the lower base of the two contactor bodies 1, and is connected to the middle part of the two contactor bodies 1 in a side fixing manner, so that the assembly position connection of the two contactor bodies 1 is more tight and reliable, and convenient for installation and disassembly.

[0046] like Figures 3 to 5As shown, as a preferred embodiment of the present invention, the fixed locking block 2 includes:

[0047] A side engaging structure is installed on the fixed locking block 2 and is used to drive the fixed locking block 2 to connect the two contactor bodies 1;

[0048] The internal and external anti-slip structures are installed on the fixed locking block 2 and are used to drive the fixed locking block 2 to be buckled on the contactor body 1 .

[0049] In order to improve the tightness of the connection between the two contactor bodies 1, a side clamping structure and an internal and external anti-slip structure are provided on the fixed locking block 2. Specifically, during assembly, the side clamping structure can drive the fixed locking block 2 to be clamped at the connection between the base and the base of the contactor body 1, thereby connecting and fixing the upper and lower parts of the contactor body 1, ensuring the tightness of the connection between the two contactor bodies 1. At the same time, an internal and external anti-slip structure is also provided to prevent the fixed locking block 2 from slipping off the contactor body 1.

[0050] like Figure 5 As shown, as another preferred embodiment of the present invention, the side clamping structure includes side limit blocks 21, which are located on both sides of the fixed locking block 2, and the side limit blocks 21 are clamped on the outer walls of the shell skirts of the two contactor bodies 1.

[0051] Specifically, during assembly, the fixed locking block 2 is connected to the contactor body 1 from the side. A connecting groove is provided on the fixed locking block 2. The skirts of the shells of the two contactor bodies 1 are engaged in the connecting groove. The side limit block 21 is pressed against the outer wall of the shell skirt to connect the two contactor bodies 1.

[0052] like Figures 3 to 5 As shown, as a preferred embodiment of the present invention, the internal and external anti-slip structures include:

[0053] An outer limit block 22, which is connected to the upper side of the side limit block 21 and engages with the outer clamping block 11 installed on the skirt of the two contactor bodies 1;

[0054] The inner limit block 23 is connected to the lower side of the side limit block 21, and the inner limit block 23 is engaged with the inner clamping block 13. The inner clamping block 13 is located in the clamping slot 12, and the clamping slot 12 is opened on the skirt of the shell of the contactor body 1. The inner limit block 23 passes through the notch on the bottom side of the shell of the contactor body 1 and is located in the clamping slot 12 and engaged with the inner clamping block 13.

[0055] Specifically, the outer clamping block 11 is an inverted L-shaped structure, and the outer limiting block 22 is engaged in the corners of the outer clamping block 11;

[0056] The inner limiting block 23 is a J-shaped structure, and a hook is provided on the top of the J-shaped structure. The hook is engaged with the outer side of the inner blocking block 13 .

[0057] When assembling the fixed locking block 2, the outer limit block 22 is engaged with the outer clamping block 11. The outer clamping block 11 is located on the upper base of the contactor body 1. The outer limit block 22 is engaged with the L-shaped corner of the outer clamping block 11. The inner clamping block 13 is located at the lower base of the contactor body 1. The inner limit block 23 passes through the notch of the lower base and enters the clamping slot 12, thereby driving the hook of the inner limit block 23 to engage with the outer side of the inner clamping block 13. The upper base and the lower base of the contactor body 1 are connected and fixed by the internal and external anti-slip structures, which further ensures the tightness of the connection between the two contactor bodies 1 and prevents the fixed locking block 2 from slipping.

[0058] like Figures 6 to 8 As shown in FIG. 1 , as a preferred embodiment of the present invention, the interlocking member 3 is an anchor-type structure, and the interlocking member 3 includes:

[0059] A rotating shaft 31 , wherein the rotating shaft 31 cooperates with the mounting seat 15 on the base of the contactor body 1 , the mounting seat 15 is located in the T-slot 14 , and the interlocking member 3 rotates in the contactor body 1 via the rotating shaft 31 ;

[0060] The limiting edges 33 are located on both sides of the rotating shaft 31 and are used to prevent the interlocking member 3 from falling out of the contactor body 1;

[0061] A boss 32 is located at the center of the interlocking member 3 and matches the base plane of the contactor body 1;

[0062] There are two lock buckles 34, which are symmetrically installed on both sides of the interlocking member 3. The two lock buckles 34 correspond to the two contactor bodies 1 respectively. When one contactor body 1 is closed, the interlocking member 3 is driven to rotate, and the other contactor body 1 is locked through the lock buckle 34.

[0063] A T-slot 14 is provided on the side of the contactor body 1 for installing the interlocking member 3 from the side. The interlocking member 3 is an anchor-type structure. The rotating shaft 31 is placed on the mounting seat 15 on the base of the contactor body 1 and rotates. Corresponding to the mounting seat 15, an elastic limiter in contact with the rotating shaft 31 is provided on the upper cover of the contactor body 1. When installing the interlocking member 3, the rotating shaft 31 passes through the T-slot 14 and applies force to the elastic limiter. The elastic limiter has a limiting effect on the rotating shaft 31, thereby improving the stability of the installation of the rotating shaft 31 and preventing the rotating shaft 31 from easily detaching. At the same time, a limiting edge 33 is provided to prevent it from falling off. A symmetrical boss 32 is provided in the center of the interlocking member 3 for cooperating with the plane of the base of the contactor body 1 to reduce its contact area and reduce movement resistance. The resistance during the action is small and the position is accurately fixed. When one of the contactor bodies 1 is closed, it drives the interlocking member 3 to rotate. The rotation of the interlocking member 3 drives the lock buckle 34 to cooperate with the contactor body 1, thereby driving the other contactor body 1 to lock.

[0064] like Figure 9 As shown in FIG. 1 , as a preferred embodiment of the present invention, the contactor further includes a guide rail 4 , and the two contactor bodies 1 are connected to the guide rail 4 via a mounting structure.

[0066] A pinch plate 16, the pinch plate 16 is located on one side of the base of the contactor body 1, and the pinch plate 16 is clamped on one side of the guide rail 4;

[0067] A card plate 17, the card plate 17 is located on the other side of the base of the contactor body 1, and the card plate 17 is clamped on the other side of the guide rail 4;

[0068] The clamp 18 is clamped on the limiting seat 19 of the base of the contactor body 1 , and both ends of the clamp 18 are provided with bent portions that press and fix with the edge of the guide rail 4 .

[0069] The contactor body 1 is installed on the guide rail 4, and is engaged with the guide rail 4 through the buckle plate 16 and the clamping plate 17. At the same time, a limit seat 19 is provided on the base of the contactor body 1, and one end of the limit seat 19 is low and the other end is high. When assembling the clamp 18, the clamp 18 is forced to slide from the low position to the high position of the limit seat 19 until the clamp 18 is engaged with the outside of the limit seat 19 and remains fixed. In addition, the two ends of the clamp 18 are bent, and the bent part is used to limit the edge of the guide rail 4 to prevent the cylindrical structure of the clamp 18 from sliding with the guide rail 4, and to prevent the guide rail 4 from being stuck in the edge of the clamp 18, thereby improving the stability of the installation of the contactor body 1 and facilitating disassembly.

[0070] 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 scope of protection of the present invention.
