[0002] A dual power transfer switch is an electrical device that automatically switches between the main power supply and the backup power supply to ensure that critical loads are continuously powered during power outages. The interlocking device of the dual power transfer switch is the core safety mechanism that ensures that the two power supplies cannot be connected at the same time, and its design directly affects the continuity of power supply and system safety.

[0003] However, traditional interlocking devices for dual power transfer switches have a simple installation structure, but they are easily restricted by the internal structure of the cabinet during power distribution connections, affecting the accuracy of installation and thus affecting the normal use of the dual power transfer switch. Utility Model Content

[0004] This utility model discloses an interlocking device suitable for dual power transfer switches, aiming to solve the technical problem that traditional interlocking devices for dual power transfer switches have a simple installation structure, but are easily restricted by the internal structure of the cabinet during power distribution connection, affecting the accuracy of installation and thus affecting the normal use of dual power transfer switches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An interlocking device for a dual-power transfer switch includes a base and a control box mounted on the bottom of the base. The top of the control box is provided with a switch body, and the interior of the control box is provided with an interlocking device body. Two first adjustment grooves are provided on each of the two outer walls of the base. Limit bolts are provided on the inner walls of the first adjustment grooves. One end of each of the two limit bolts is connected to the same mounting strip. Two symmetrical second adjustment grooves are provided on the same mounting strip. Fastening bolts are provided on the inner walls of the second adjustment grooves.

[0006] By adopting the above technical solution, the position of the mounting strip can be changed longitudinally through the first adjustment groove, and the mounting strip can be adjusted as a whole. The two independent second adjustment grooves on the mounting strip can be used for the lateral adjustment of the position of the fastening bolts. During the overall installation process of the device, the installation position can be precisely controlled, ensuring that the interlocking device can work stably.

[0007] As a further embodiment of this utility model, the bottom of the base is provided with a groove.

[0008] By adopting the above technical solution, the groove is designed to bring the control box as close as possible to the back of the base. As the base is installed with fastening bolts, there is a certain gap between the support of the mounting strip and the limit bolt on the back of the base and the installation position, which helps to improve the heat dissipation effect on the back of the control box.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Ensuring stable installation structure: Unlike traditional fixing methods, the installation method in this solution combines horizontal and vertical adjustments. During the actual installation process, adjustments can be made according to the on-site installation environment to ensure that the installation position is appropriate, accurate, and highly stable.

[0010] 2. Excellent heat dissipation: The grooves are designed to alter the thickness of the back of the base and the control box. By utilizing the gap between the base and the installation position during installation, effective heat dissipation space is provided, ensuring stable operation of the equipment.

[0011] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An interlocking device for a dual power transfer switch includes a base 5 and a control box 1 installed at the bottom of the base 5. The top of the control box 1 is provided with a switch body 2, and the inside of the control box 1 is provided with an interlocking device body. Two first adjustment grooves 11 are provided on each of the two outer walls of the base 5. Limit bolts 8 are provided on the inner wall of the first adjustment grooves 11. One end of the two limit bolts 8 is connected to the same mounting strip 6. Two symmetrical second adjustment grooves 12 are provided on the same mounting strip 6. Fastening bolts 7 are provided on the inner wall of the second adjustment grooves 12.

[0021] Specifically, the position of the mounting strip 6 can be changed longitudinally through the first adjustment groove 11, and the mounting strip 6 can be adjusted as a whole. The two independent second adjustment grooves 12 on the mounting strip 6 can be used for the lateral adjustment of the position of the fastening bolt 7. During the overall installation process of the device, the installation position can be precisely controlled, ensuring that the interlocking device can work stably.

[0022] Among them, a fastening sleeve 9 is screwed onto the outer wall of the limiting bolt 8, and a baffle is also fixedly connected to the outer wall of the limiting bolt 8. The baffle and the fastening sleeve 9 are located on both sides of the base 5, respectively.

[0023] It should be noted that anti-slip textures 10 are provided on both sides of the first adjustment groove 11. After the limit bolt 8 is adjusted to the appropriate position along the first adjustment groove 11, it is tightened by the fastening sleeve 9 and the baffle. During the tightening process, the fastening sleeve 9 and the anti-slip textures 10 press against each other, increasing the friction and preventing the limit bolt 8 from shifting in the first adjustment groove 11 during the limiting process.
