Technical Field
[0001] The present application relates to the technical field of magnetic latching relays, and in particular to a magnetic latching relay that is easy to disassemble. Background Art
[0002] A magnetic latching relay is a switch that controls a circuit. The relay can open or close the circuit. The magnetic latching relay relies on the action of permanent magnets to ensure that the circuit is normally closed or normally open.
[0003] Reference Figure 1 In the related technology, the relay includes an upper shell, a lower shell and a driving structure. The driving structure can realize the basic functions of the magnetic holding relay. A plurality of bolts are provided on the upper shell. The bolts can pass through the upper shell and be threadedly connected with the lower shell. When the staff installs the upper shell and the lower shell, the staff needs to first threadably connect the plurality of bolts with the lower shell to realize the mutual fixation of the upper shell and the lower shell.
[0004] When the relay needs to be repaired or inspected, the staff needs to tighten multiple bolts, the staff's operation steps are cumbersome, and it is time-consuming and laborious for the staff to disassemble the upper shell and the lower shell. Utility Model Content
[0005] In order to improve the problem of cumbersome disassembly of the upper shell and the lower shell, the present application provides a magnetic latching relay that is easy to disassemble.
[0006] The present application provides a magnetic latching relay that is easy to disassemble, which adopts the following technical solution:
[0007] A magnetic latching relay that is easy to disassemble comprises an upper shell, a lower shell and a driving structure. The upper shell is provided with a fixing block, the lower shell is provided with a locking block, and the fixing block is provided with a locking hole for inserting the locking block. When the locking block is inserted into the locking hole, the upper shell is fixed to the lower shell.
[0008] By adopting the above technical solution, the locking block is inserted into the locking hole, so that the hole wall of the locking hole restricts the locking block, allowing the locking block to be fixed to the fixing block, thereby achieving the fixation of the upper shell and the lower shell, so that the staff can disassemble or install the upper shell and the lower shell, so as to facilitate the staff to repair the relay.
[0009] Optionally, the locking block has a locking surface, the locking surface is inclined toward the insertion direction of the upper shell and away from the lower shell, and the locking surface is located in the insertion path of the fixing block.
[0010] By adopting the above technical solution, the locking surface is tilted and the locking surface is located in the insertion path of the fixed block, so that the fixed block can slide along the locking surface and the locking block can be smoothly inserted into the locking hole, thereby facilitating the staff to lock the fixed block and the locking block.
[0011] Optionally, the driving structure includes a movable plate, an indicator bar is provided on the movable plate, a through hole is opened on the upper shell, and the indicator bar is located in the through hole. When the circuit is closed or disconnected, the movable plate moves on both sides, and the indicator bar is located on different sides of the through hole.
[0012] By adopting the above technical solution, when the circuit is closed or disconnected, the movable plate can move on both sides so that the indicator bar can be located on both sides of the perforation. When people check whether the relay is normal, they can directly judge the circuit condition by observing the position of the indicator bar, so that people do not need to detect whether the circuit is connected, which is convenient for people to check the relay.
[0013] Optionally, a pop-up plate is provided on the through hole, a pop-up groove is opened on the through hole, a pop-up member is provided in the pop-up groove, and the pop-up member drives the pop-up plate to seal the opening of the through hole.
[0014] By adopting the above technical solution, the pop-up member is arranged in the pop-up groove, so that the pop-up member can drive the pop-up plate to seal the through hole, so that foreign debris cannot enter the interior of the relay through the through hole, thereby reducing the impact of foreign debris on the normal use of the relay.
[0015] Optionally, a limit spring is provided in the pop-up slot, a limit block is provided on the limit spring, and a limit hole is provided on the pop-up plate. When the limit block is located in the limit hole, the pop-up plate is completely located in the pop-up slot.
[0016] By adopting the above technical solution, the limit block is driven by the limit spring to be inserted into the limit hole, so that the pop-up plate can be completely located in the pop-up groove, so that the pop-up plate does not block the perforation, and the indicator bar can leak out at the perforation. People do not need to press the pop-up plate manually, which reduces people's operating steps and facilitates people's observation.
[0017] Optionally, an operation bar is slidably connected in the limiting hole, and an operation hole connected to the pop-up slot is opened on the upper shell. When the limiting block is located in the limiting hole, the operation bar protrudes from the operating hole; when the operation bar is completely located in the operating hole, the limiting block is separated from the limiting hole.
[0018] By adopting the above technical solution, the operating bar slides in the limiting hole. When the stop block is located in the limiting hole, the stop block abuts against the operating bar, allowing the operating bar to protrude from the operating hole, so that people can press the operating bar to insert the operating bar into the operating hole, so that the limiting block is disengaged from the limiting hole, thereby allowing the pop-up plate to slide in the pop-up slot, making it easy to release the limit block from locking the pop-up plate.
[0019] Optionally, a fixing groove for inserting the pop-up plate is provided on the hole wall of the perforation, and when the pop-up plate is inserted into the fixing groove, the pop-up plate completely blocks the perforation.
[0020] By adopting the above technical solution, the pop-up plate is inserted into the fixed groove, and the groove wall of the fixed groove restricts the pop-up plate, so that the pop-up plate can stably block the perforation, and the pop-up plate is not easy to shake in the perforation, so that the pop-up plate can better block the perforation.
[0021] Optionally, a first magnet is provided on the pop-up plate, and a second magnet is provided in the fixed groove. When the pop-up plate is located in the fixed groove, the first magnet attracts the second magnet.
[0022] By adopting the above technical solution, the first magnet attracts the second magnet, so that the pop-up plate can be fixed in the fixing groove, making it difficult for the pop-up plate to move due to the vibration of the limit spring, so that the pop-up plate can be stably located in the upper shell.
[0023] Optionally, a reinforcement groove is provided on the pop-up plate, and the indicator strip can slide in the reinforcement groove.
[0024] By adopting the above technical solution, the indicator bar slides in the reinforcement groove, and the groove wall of the reinforcement groove restricts the indicator bar, so that the indicator bar can restrict the pop-up plate, so that the pop-up plate will not shake in the perforation, and the pop-up plate can be stably located in the perforation.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. Insert the locking block into the locking hole so that the hole wall of the locking hole restricts the locking block, so that the locking block can be fixed to the fixing block to achieve the fixation of the upper shell and the lower shell, so that the staff can disassemble or install the upper shell and the lower shell to facilitate the staff to repair the relay.
[0027] 2. By having the indicator strip on different sides of the perforation, people can know the state of the circuit through the position of the indicator strip, so that people do not need to check whether the circuit is connected, which is convenient for people to detect the relay.
