[0029] Referring to Figure 1 、 Figure 2 and Figure 3 , the utility model provides an embodiment: a relay mounting rail in an electric control cabinet, which includes a flat rail 1. Two first hooks 2 are clamped in the middle of the flat rail 1. A connecting member 3 is fixedly connected to the top ends of the two first hooks 2. A movable plate 4 is slidably connected to the middle of the bottom end of the connecting member 3. A first fixing plate 5 is fixedly connected to the rear side of the middle of the bottom end of the movable plate 4. A spring 6 is fixedly connected to the middle of the front end of the first fixing plate 5. The other end of the spring 6 is fixedly connected to a second fixing plate 7. Connecting blocks 8 are fixedly connected to the left and right sides of the middle of the bottom end of the movable plate 4. Second hooks 10 are fixedly connected to the bottom ends of the two connecting blocks 8. Extension assemblies 9 are arranged at the left and right ends of the inner side wall of the flat rail 1; A plurality of uniformly distributed fixing screw holes 11 are formed in the front and rear sides of the top end of the connecting member 3; A plurality of uniformly distributed heat dissipation grooves 12 are formed in the middle of the top end of the connecting member 3;

[0030] Specifically: A plurality of fixing screw holes 11 are uniformly formed in the front and rear sides of the top end of the connecting member 3. These fixing screw holes 11 are very uniformly distributed, which can facilitate the connection between the relay and the connecting member 3. At the same time, a plurality of heat dissipation grooves 12 are also uniformly formed in the middle of the top end of the connecting member 3. These heat dissipation grooves 12 help to improve the heat dissipation effect and ensure that the connection part between the relay and the connecting member 3 does not generate high temperature. Through this design, the connecting member 3 not only has a good fixing function but also has excellent heat dissipation performance.

[0031] Referring to Figure 1 、 Figure 2 and Figure 4 , the extension assembly 9 includes a plurality of sliding grooves 901, and the plurality of sliding grooves 901 are all formed in the left and right ends of the inner side wall of the flat rail 1. Extension rails 903 are arranged at the left and right ends of the flat rail 1. Sliders 902 are fixedly connected to the front and rear ends of the two extension rails 903. Fixing grooves 904 are formed in the front and rear sides of the far ends of the two extension rails 903 away from each other. Adapter pieces 905 are fixed to the inner side walls of the plurality of fixing grooves 904; The top end of the second fixing plate 7 is fixedly connected to the front side of the middle of the bottom end of the connecting member 3. The plurality of sliders 902 are all slidably connected to the inner side walls of the sliding grooves 901;

[0032] Specifically; The plurality of sliding grooves 901 are formed in the left and right ends of the inner side wall of the flat rail 1. The setting of these sliding grooves 901 is to ensure the flexibility and adjustability of the extension rail 903. Sliders 902 are fixedly connected to the front and rear ends of the extension rail 903, and these sliders 902 are slidably connected to the inner side walls of the sliding grooves 901.

[0034] Specifically: rubber pads 13 are fixedly connected to the positions of the remote ends of the multiple adapters 905. The function of these rubber pads 13 is to provide certain buffering and shock absorption effects when the adapters 905 are in contact with other components, thereby protecting the connecting components from damage. The material of the rubber pads 13 usually has good elasticity and durability, and can adapt to various working environments and temperature changes. At the same time, the fixing bolts 15 are tightly combined with the positioning holes 14 through threads, thereby firmly fixing the adapters 905 in their corresponding positions. The selection and design of the fixing bolts 15 take into account factors such as the material, thickness, and working environment of the adapters 905 to ensure that they have sufficient strength and durability to withstand various loads and stresses during long-term use.

[0035] Working principle: When the device needs to be used, first fix the relay on the top of the connecting piece 3, and then use the first hook 2 fixed at the bottom end of the connecting piece 3 to snap the connecting piece 3 onto the flat rail 1. At the same time, two second hooks 10 are fixed on the movable plate 4 that slides in the middle of the bottom end of the connecting piece 3, and through the spring 6 between the first fixing plate 5 fixed at the rear end of the middle of the movable plate 4 and the second fixing plate 7 fixed at the bottom end of the connecting piece 3, the elasticity of the spring 6 can be used to make the movable plate 4 slide, so that the second hook 10 can be snapped onto the other end of the flat rail 1, making the connecting piece 3 fixed on the flat rail 1 without shaking. And by opening two sliding grooves 901 on the adjacent side of the inner side wall of the flat rail 1 and sliding sliders 902 in both of the two sliding grooves 901, the flexibility and adjustability of the extension rail 903 can be ensured, so that when the length of the flat rail 1 is not enough, the extension rail 903 can be pulled out to fix the device on an object.
