[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0020] like Figs. 1-3As shown, this utility model proposes a profile connector for a control cabinet, including a tail rod 1, a top rod 2 at one end of the tail rod 1, and a connecting seat 3 between the tail rod 1 and the top rod 2. The two ends of the connecting seat 3 are respectively installed close to one end of the tail rod 1 and the top rod 2. One end of the connecting seat 3 is fixedly connected to one end of the tail rod 1, and the other end of the connecting seat 3 is fixedly connected to one end of the top rod 2. One end of the top rod 2 is tapered, which allows the operator to more easily access the control cabinet via the top rod 2. This device is assembled with the mounting holes of the control cabinet. An assembly chamber 4 is provided at one end of the top rod 2 near the tail rod 1. One end of the assembly chamber 4 is arc-shaped. A spring piece 5 and a positioning block 6 are respectively installed inside the assembly chamber 4. One end of the positioning block 6 is installed correspondingly to the end of the connecting seat 3 near the top rod 2, and is fixedly connected to one end of the connecting seat 3. The upper and lower sides of the positioning block 6 are installed correspondingly to the inner wall of the assembly chamber 4, and are fixedly connected to the inner wall of the assembly chamber 4. The spring piece 5 is V-shaped. The top of the spring piece 5 is in contact with the inner wall of the assembly chamber 4. When the spring piece 5 is in the assembled state, the top of the positioning block 6 is in contact with the inner wall of the spring piece 5 at the included angle. Rubber pads 11 are provided at both ends of the spring piece 5. The mounting ends of the rubber pads 11 are fixedly connected to the end feet of the spring piece 5. Springs 7 are provided between the two sides of the positioning block 6 and the inner wall of the spring piece 5. One end of the spring 7 is installed corresponding to one side of the positioning block 6 and fixedly connected to the positioning block 6. The other end of the spring 7 is installed corresponding to one side of the inner wall of the spring piece 5. The other end of the spring 7 is fixedly connected to the spring piece 5. The spring 7 can provide stronger elastic force to the two ends of the spring piece 5. The inner ring of the spring 7 is provided with a guide rod 8. The spring piece 5 has pin holes 12 at both ends. The mounting end of the guide rod 8 is installed corresponding to one side of the positioning block 6. One end of the guide rod 8 is fixedly connected to the positioning block 6. When the spring piece 5 is in a compressed state, the top end of the guide rod 8 is installed corresponding to the pin hole 12. The guide rod 8 can guide and limit the two ends when the spring piece 5 is in a compressed state.

[0021] A fastening nut 9 is fitted onto the outer ring of the tail rod 1. The outer ring of the tail rod 1 has a threaded groove, and the inner wall of the fastening nut 9 has an internal thread. The inner ring of the fastening nut 9 corresponds to the outer ring of the tail rod 1, and the fastening nut 9 is threadedly connected to the tail rod 1. The fastening nut 9 can cooperate with the spring 5 to securely assemble the tail rod 1 with the control cabinet profile. When the fastening nut 9 is fully tightened, the rubber pad 11, through its own elasticity, increases the pressure between the spring 5 and the back of the profile, thereby increasing the friction between the spring 5, the nut 9, and the profile. This greatly prevents the nut 9 from loosening due to vibration and also avoids the inconvenience of the operator tightening the nut 9 from the back of the profile. A mounting seat 10 is provided at the end of the rod 1 furthest from the top rod 2. A connecting seat 2 13 is provided on one side of the mounting seat 10. The mounting end of the connecting seat 2 13 is fixedly connected to one side of the mounting seat 10. The connecting seat 2 13 is oriented... The assembly base 10 is hollow, with one end of the tail rod 1 corresponding to the inner wall of the connecting seat 2 13. The outer ring of one end of the tail rod 1 is fixedly connected to the inner wall of the connecting seat 2 13. The connecting seat 2 13 allows the assembly base 10 and the tail rod 1 to be in a fixed assembly state. The side of the assembly base 10 away from the tail rod 1 is arc-shaped. The arc-shaped design of the assembly base 10 allows the operator to ventilate and dissipate heat from the back of the electronic components when assembling them, thus protecting the electronic components. Both ends of the arc-shaped side of the assembly base 10 are provided with vibration damping pads 14. The mounting ends of the vibration damping pads 14 are fixedly connected to the assembly base 10. The vibration damping pads 14 can prevent the electronic components from directly contacting the assembly base 10 and causing damage. At the same time, they can buffer the vibration generated by the electronic components during operation, thus protecting the electronic components when they are in the assembly state.

[0022] In this embodiment, the operator first inserts the tapered end of the push rod 2 into the corresponding assembly hole on the control cabinet. When the push rod 2 is inserted into the assembly hole, the operator pushes the tail rod 1 through the assembly base 10, causing the push rod 2 to slide along the assembly hole. At this time, the inner wall of the assembly hole squeezes the outer side of the spring piece 5, causing the spring piece 5 to be gradually compressed into the assembly chamber 4. When the spring piece 5 is compressed, it squeezes the spring 7. At this time, the top end of the guide rod 8 is inserted into the pin hole 12 on the spring piece 5 to limit and guide the spring piece 5. When the push rod 2 drives the spring piece 5 to disengage... When mounting the spring 5 on the control cabinet, it is no longer subjected to the squeezing force of the inner wall of the mounting hole. Under the elasticity of its own and the reset action of the spring 7, the spring 5 is in its initial state. At this time, the two ends of the spring 5 drive the rubber pad 11 to fit against the back side of the profile inside the control cabinet. Then the operator rotates the fastening nut 9 so that the fastening nut 9 fits tightly against the other side of the profile inside the control cabinet after rotation. After the fastening nut 9 continues to rotate, the two ends of the spring 5 fit tightly against the profile through the rubber pad 11, thereby completing the assembly operation of this device.

[0023] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
