Description

Technical Field

[0001] This utility model relates to the field of electromagnetic relay technology, and in particular to a push rod structure for a push rod type electromagnetic relay. Background Technology

[0002] An electromagnetic relay is an electronic control device that consists of a control system and a controlled system. It is commonly used in automatic control circuits. Essentially, it acts as an "automatic switch" that uses a smaller current and lower voltage to control a larger current and higher voltage. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching. The push-rod type electromagnetic relay is a common type. Its working principle is that when the coil is energized, the armature drives the push rod to move, which in turn causes the moving contact on the moving spring connected to the push rod to contact the stationary contact on the stationary spring, thus energizing the high-voltage end.

[0003] Chinese Patent Publication No. CN212907576U discloses a push rod structure for a push rod type electromagnetic relay, including a push rod body. The push rod body includes a horizontally arranged pushing block. The key feature is that the front end of the pushing block has two positioning protrusions that protrude forward. The two positioning protrusions are arranged side-by-side with a gap between them, forming a positioning groove for embedding and installing a moving spring. The width of the positioning groove matches the width of the moving spring to be installed. The advantage is that the positioning groove formed by the two positioning protrusions provides a stable installation position for the moving spring, ensuring stable installation between the push rod and the moving spring when applied to the relay, thereby ensuring the electrical performance and pass rate of the relay using this push rod.

[0004] However, the distance between the first and second baffle plates in the above-mentioned push rod structure is limited, which means that the push rod structure can only be used for relays of a limited size, i.e., its applicable range is small. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a push rod structure for a push rod type electromagnetic relay.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A push rod structure for a push rod type electromagnetic relay includes a first partition plate and a second partition plate. A first square tube is fixedly connected to the left side of the first partition plate, and a second square tube is fixedly connected to the right side of the second partition plate. A groove is formed on the right side of the first partition plate, and a first hexagon socket screw is rotatably connected to the inner cavity of the groove. The left end of the first hexagon socket screw passes through the second square tube. A limiting plate is located in the inner cavity of the second square tube. A front mounting plate is provided on the left side of the second partition plate, and a baffle is provided on the front side of the front mounting plate. A rectangular groove is formed on the left side of the second partition plate, and a second hexagon socket screw passes through the baffle plate near the right side. The right side of the baffle plate is movably inserted into the inner cavity of the rectangular groove.

[0008] Furthermore, the right side of the first partition plate is fixedly connected to an embedded part, the right end of the second square tube is sealed, and the right end of the second square tube is movably inserted into the inner cavity of the first square tube.

[0009] Furthermore, the second square tube is threadedly connected to the first hexagon socket screw, and a limit plate is fixedly connected to the left end of the first hexagon socket screw.

[0010] Furthermore, a guide slope is provided on the left side of the front mounting plate, and the cross-section of the front mounting plate is U-shaped.

[0011] Furthermore, the baffle has an L-shaped cross-section, and the inner side of the baffle is in contact with the left side of the front mounting plate.

[0012] Furthermore, the second hexagon socket screw is rotatably connected to the inner cavity of the rectangular slot, and the second hexagon socket screw is threadedly connected to the baffle.

[0013] Furthermore, a limiting rod is movably provided through the baffle near the center position, and the limiting rod is fixedly connected to the front side of the front mounting plate.

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

[0015] 1. This utility model discloses a push rod structure for a push rod type electromagnetic relay. When it is necessary to adjust the distance between the first and second spacers, the first internal hexagon screw is turned by an external wrench. When the first internal hexagon screw rotates, the second square tube moves relative to the first internal hexagon screw under the action of the thread. The second square tube drives the second spacer to move, and the second square tube moves inside the cavity of the first square tube, thereby adjusting the distance between the first and second spacers. This allows the device to be used for the installation of relays of different sizes, greatly improving its applicability.

[0016] 2. This utility model discloses a push rod structure for a push rod type electromagnetic relay. When the front mounting plate is used to install the moving spring of the relay, the moving spring of the relay is inserted into the inner cavity of the front mounting plate. Then, by turning the second internal hexagon screw with an external wrench, the baffle moves to the right relative to the second internal hexagon screw under the action of the thread. The baffle moves in the inner cavity of the rectangular groove. When the baffle moves to the left side of the front mounting plate, the baffle limits the moving spring of the relay, preventing the moving spring of the relay from detaching from the front mounting plate, thereby ensuring that the push rod structure and the relay work together.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0031] Please see Figure 1-9 This utility model provides a technical solution: a push rod structure for a push rod type electromagnetic relay, including a first partition plate 2 and a second partition plate 3. An embedded part 4 is fixedly connected to the right side of the first partition plate 2, a first square tube 1 is fixedly connected to the left side of the first partition plate 2, and a second square tube 5 is fixedly connected to the right side of the second partition plate 3. The right end of the second square tube 5 is sealed and movably inserted into the inner cavity of the first square tube 1. A groove 7 is provided on the right side of the first partition plate 2. A first hexagon socket screw 8 is rotatably connected to the inner cavity of the groove 7. The left end of the first hexagon socket screw 8 passes through the second square tube 5. The second square tube 5 is threadedly connected to the first hexagon socket screw 8. A limiting plate 9 is fixedly connected to the left end of the first hexagon socket screw 8. The limiting plate 9 is located in the inner cavity of the second square tube 5.

[0032] A front mounting plate 6 is provided on the left side of the second partition plate 3. A guide slope 10 is provided on the left side of the front mounting plate 6. The cross-section of the front mounting plate 6 is U-shaped. A baffle 11 is provided on the front side of the front mounting plate 6. A rectangular groove 13 is provided on the left side of the second partition plate 3. A second hexagon socket screw 12 is provided through the baffle 11 near the right side. The right side of the baffle 11 is movably inserted into the inner cavity of the rectangular groove 13. The cross-section of the baffle 11 is L-shaped. The inner side of the baffle 11 fits against the left side of the front mounting plate 6. The second hexagon socket screw 12 is rotatably connected to the inner cavity of the rectangular groove 13.

[0033] Working Principle: This utility model discloses a push rod structure for a push rod type electromagnetic relay. During use, when it is necessary to adjust the distance between the first partition plate 2 and the second partition plate 3, the first internal hex screw 8 is turned by an external wrench. When the first internal hex screw 8 rotates, the second square tube 5 moves relative to the first internal hex screw 8 under the action of the thread. The second square tube 5 drives the second partition plate 3 to move. The second square tube 5 moves within the cavity of the first square tube 1, thereby adjusting the distance between the first partition plate 2 and the second partition plate 3. This allows the device to be used for the installation of relays of different sizes, greatly improving its applicability.

[0034] When the front mounting plate 6 is used to install the moving spring of the relay, the moving spring of the relay is inserted into the inner cavity of the front mounting plate 6. Then, by turning the second internal hex screw 12 with an external wrench, the baffle 11 moves to the right relative to the second internal hex screw 12 under the action of the thread. The baffle 11 moves in the inner cavity of the rectangular groove 13. When the baffle 11 moves to the left side of the front mounting plate 6, the baffle 11 limits the moving spring of the relay to prevent the moving spring of the relay from detaching from the front mounting plate 6, thereby ensuring that the push rod structure and the relay work together.
