Description

Technical Field

[0001] The utility model relates to the technical field of relays, and in particular to a combined relay that is convenient for capacity expansion. Background Art

[0002] A relay is an electrical control device. When the change in input quantity reaches the specified requirement, it causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system and the controlled system. It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] Patent No. CN219226165U discloses a combined relay that is easy to expand. The top sliding assembly of the mounting seat is equipped with a limit assembly, and the limit assembly is equipped with a relay structure. The relay structure is a first relay unit and a second relay unit that are assembled with each other, and the first relay unit and the second relay unit have the same structure. The left side wall of the relay body is provided with a snap-fit ​​assembly, and the right side wall of the relay body is provided with a plug-in assembly that is compatible with the snap-fit ​​assembly. The distance between the front limit frame and the rear limit frame can be adjusted according to the size of the relay structure, which is convenient for improving the adaptability of the relay structure and facilitating the limited installation of the relay structure. The quick-release installation of the snap-fit ​​assembly and the plug-in assembly can achieve the purpose of expansion while ensuring the stability between the relay structures.

[0004] However, the above-mentioned combined relay which is convenient for expansion still has the following shortcomings:

[0005] The above-mentioned combined relay is difficult to disassemble between the assembled relays because the length of the limit assembly is not adjustable and the operating space between the relays is limited. When a relay needs to be disassembled, repaired or replaced, the combined relay needs to be taken out as a whole to complete the partial disassembly, which is inconvenient. In view of this, we propose a combined relay that is easy to expand. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a modular relay that is easy to expand, so as to solve the technical problem that the length of the limit assembly of the above-mentioned modular relay is not adjustable and the operating space between the relays is limited, so it is difficult to perform disassembly operations between the assembled relays. When a certain relay needs to be disassembled, repaired and replaced, the modular relay needs to be taken out as a whole to complete the partial disassembly, which is inconvenient to operate.

[0007] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a modular relay that is convenient for expansion, including a positioning bracket, a plurality of relay bodies are distributed inside the positioning bracket, and a convenient mechanism is provided on the side of the relay body;

[0008] The convenient mechanism includes a card plate, which is fixed on one side of the surface of the relay body.

A pull rod is connected to the middle of the card rod surface. A limiting ring plate is fixedly sleeved near the end surface of the card rod, and a spring is connected to one side of the limiting ring plate.

[0009] Preferably, the clamping plate is matched and engaged with the limiting slot frame, and the end of the clamping rod is matched and engaged with the inside of the clamping plate.

[0010] Preferably, the clamping rod forms an elastic structure through a limiting ring plate, a spring and a limiting groove frame, and the clamping rod is fixedly connected to the pull rod.

[0013] Preferably, the bracket is threadedly connected to the limiting screw, the limiting screw is in an I-shape, and a slot matching the bottom of the limiting screw is formed on the top of the relay body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model drives the clamping rod to move by pulling the pull rod outward, so that the end of the clamping rod is effectively hidden in the limit slot frame, which makes it easier for the clamping plate of another relay body to be clamped in the limit slot frame of the relay body. After that, the pull rod is released, and the end of the clamping rod pops out under the influence of the spring rebound force, and is effectively clamped in the clamping plate of another relay body, completing the rapid assembly between the relay bodies. When disassembling a relay body other than the side, the pull rods on both sides of the relay body are pulled outward, and the relay body is moved up at the same time, which is convenient and fast.

Then, the combined relay bodies are moved to the inside of the left bracket and the right bracket, and the limiting screw is screwed at the same time to make its bottom effectively engage with the top of the side relay body, thereby limiting the combined relay bodies as a whole. When it is necessary to disassemble a side relay body, the limiting screw is screwed to make its bottom away from the side relay body, and the pull rod close to the card plate is pulled outward at the same time, and then the side relay body is moved left or right to achieve disassembly, which is more convenient.

A limiting ring plate 305 is fixedly sleeved on the surface of the card rod 303 near the end, and a spring 306 is connected to one side of the limiting ring plate 305. Furthermore, the card rod 303 forms an elastic structure with the limiting groove frame 302 through the limiting ring plate 305, the spring 306, and the card rod 303 and the pull rod 304 are fixedly connected. The utility model drives the clamping rod 303 to move by pulling the pull rod 304 outward, so that the end of the clamping rod 303 is effectively hidden in the limiting groove frame 302, thereby facilitating the clamping plate 301 of another relay body 2 to be clamped in the limiting groove frame 302 of the relay body 2. Thereafter, the pull rod 304 is released, and the end of the clamping rod 303 pops out under the influence of the rebound force of the spring 306, and is effectively clamped in the clamping plate 301 of another relay body 2, completing the rapid assembly between the relay bodies 2. When disassembling a relay body 2 other than the side, the pull rods 304 on both sides of the relay body 2 are pulled outward, and the relay body 2 is moved up at the same time, which is convenient and fast.
