A structure for easy maintenance of a two-position five-way solenoid valve

Abstract

This utility model provides a structure for a 2-position 5-way solenoid valve that facilitates maintenance, relating to the technical field of 2-position 5-way solenoid valves. The disassembly mechanism includes a 2-position 5-way solenoid valve body, with a magnetic valve cover at one end. The magnetic valve cover and the valve body are fitted together. This utility model connects the 2-position 5-way solenoid valve body and the magnetic valve cover by fitting them together. A connecting plate automatically contacts one side of the valve body. Rotating the locking arm 180 degrees allows it to enter the recess of the connecting plate. Once inside, the two inclined surfaces contact each other. The inclined force of the locking arm creates a lateral force on the connecting plate, ensuring a tight lock between the magnetic valve cover and the valve body. To disassemble, simply rotating the locking arm in the opposite direction releases the lateral pressure on the connecting plate, quickly disconnecting the magnetic valve cover from the valve body.

Description

Technical Field

[0001] This utility model relates to the field of two-position five-way solenoid valve technology, and in particular to a structure for a two-position five-way solenoid valve that is easy to maintain. Background Technology

[0002] A 2-position 5-way solenoid valve is a basic automation component used to control fluids; it belongs to the actuator category and is not limited to hydraulic or pneumatic systems. Solenoid valves are used to control the direction of hydraulic flow. Factory machinery is generally controlled by hydraulic cylinders, hence the use of solenoid valves.

[0003] In existing technologies, two-position five-way solenoid valves can be used in a variety of different production fields. By precisely controlling the bidirectional movement of double-acting pneumatic actuators through two-position five-way solenoid valves, the on / off switching of air circuits and pressure regulation can be realized, thereby providing efficient power control support for automated production processes in various fields. However, the internal seals of a 2-position 5-way solenoid valve may age during use, leading to air leakage. During maintenance, the end cap of the 2-position 5-way solenoid valve needs to be removed. The end cap is connected to the 2-position 5-way solenoid valve by a self-tapping screw. Due to repeated disassembly and removal, the self-tapping screw may become stripped, making it difficult for the tool to effectively engage with the self-tapping screw during disassembly, thus making disassembly difficult.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a structure for an easy-to-maintain two-position five-way solenoid valve, including an auxiliary mechanism 2 on the top side of a disassembly mechanism 1. The disassembly mechanism 1 includes a two-position five-way solenoid valve body 11, with a magnetic valve cover 12 at one end of the body. One end of the body 11 corresponds to and fits into one end of the magnetic valve cover 12. A connecting plate 13 is provided at one edge of the magnetic valve cover 12, and the edge of the cover 12 is fixedly connected to one side of the connecting plate 13. A locking arm 16 is provided in the top recess of the connecting plate 13, and the top recess of the connecting plate 13 contacts one inclined surface of the locking arm 16. A rotating member 15 is provided at one end of the locking arm 16, and one end of the locking arm 16 is rotatably connected to one end of the rotating member 15. One bottom end of the rotating member 15 is connected to the fixed plate 16. The top side of the fixed plate 14 is fixedly connected, and a mother cavity 19 is provided on the top side of the fixed plate 14. The top side of the fixed plate 14 is fixedly connected to one end of the bottom side of the mother cavity 19. A spring 110 is provided on the inner surface of the mother cavity 19. One end of the inner surface of the mother cavity 19 is fixedly connected to one end of the spring 110. A sub-rod 18 is provided on one end of the spring 110. One end of the spring 110 is fixedly connected to one end of the sub-rod 18. The outer side of the sub-rod 18 is slidably connected to the inner surface of the mother cavity 19. A positioning rod 17 is provided on one end of the sub-rod 18. One end of the sub-rod 18 is fixedly connected to one end of the positioning rod 17. The outer side of one end of the positioning rod 17 is slidably engaged with the inner wall of the locking arm 16. The top side of the two-position five-way solenoid valve body 11 is fixedly connected to the bottom side of the fixed plate 14. The top side of the two-position five-way solenoid valve body 11 is in contact with one side of the connecting plate 13.

[0021] In this embodiment, the maintenance-friendly two-position five-way solenoid valve structure allows for easy maintenance. During use, one end of the two-position five-way solenoid valve body 11 is connected to the solenoid valve cover 12 via a fitting mechanism, achieving initial positioning during the connection process. A connecting plate 13 is installed on one side of the connecting plate 13. During the connection process between the solenoid valve cover 12 and the two-position five-way solenoid valve body 11, the connecting plate 13 automatically contacts one side of the two-position five-way solenoid valve body 11. Simultaneously, a recess with a slope is provided on the top side of the connecting plate 13. Therefore, by installing a fixing plate 14 on one side of the two-position five-way solenoid valve body 11, and fixing a rotating... The moving part 15, and the left and right ends of the rotating part 15 are rotatably connected to the inner wall of one end of the locking arm 16. One side of the locking arm 16 also has a bevel. When the locking arm 16 is rotated 180 degrees, it enters the recess of the connecting plate 13. After entering, the two bevels will contact each other. At this time, pressure is applied to the locking arm 16, and the pushing force of the bevel of the locking arm 16 creates a lateral force on the connecting plate 13, so that the solenoid cover 12 and the two-position five-way solenoid valve body 11 are tightly locked and fixed when they are combined, eliminating the gap in the initial positioning stage, and ensuring the structural stability after the two are connected, thus ensuring the sealing performance of the two-position five-way solenoid valve body 11 and the solenoid cover 12. A female cavity 19 is installed on the top side of the fixed plate 14. A male rod 18 is designed on the inner surface of the female cavity 19. The male rod 18 can slide on the inner surface of the female cavity 19. A spring 110 is installed between the female cavity 19 and the male rod 18. At the same time, a positioning rod 17 is fixed to one end of the male rod 18. The two are integrated. When the locking arm 16 contacts the connecting plate 13, the positioning rod 17 contacts the locking arm 16 first. The ends of the positioning rod 17 are all beveled. At the same time, the locking arm 16 has holes corresponding to the positioning rod 17. Therefore, when the locking arm 16 is about to contact the connecting plate 13, it will generate a lateral force on the positioning rod 17, thereby causing the male rod 18 to slide into the female cavity 19. As the locking arm 16 moves to the preset position, when the hole on the locking arm 16 aligns with the axis of the positioning rod 17, the elastic potential energy of the spring 110 is released instantaneously, pushing the sub-rod 18 to drive the positioning rod 17 to quickly embed into the hole of the locking arm 16, forming an automatic locking, fixing the position of the locking arm 16 after rotation, ensuring that the structural connection between the locking arm 16 and the connecting plate 13 is not interrupted. Finally, by installing a push plate 111 on the top side of one end of the sub-rod 18, a lateral force is applied to the push plate 111, and the positioning rod 17 exits from the locking arm 16. At this time, the locking arm 16 is reversed 180 degrees, thereby releasing the effective fixation of the magnetic valve cover 12 and the two-position five-way solenoid valve. Example

[0022] like Figures 1-3 As shown, the auxiliary mechanism 2 includes a protrusion 21, a magnetic block 22 is provided on the top side of the protrusion 21, the top side of the protrusion 21 is fixedly connected to the outer side of the magnetic block 22, a magnetic block 23 is provided on the top side of the magnetic block 22, the top side of the magnetic block 22 and one side of the magnetic block 23 attract each other, the outer side of the magnetic block 23 is fixedly connected to one side of the locking arm 16, and a fixing plate 14 is provided on the bottom side of the protrusion 21, the bottom side of the protrusion 21 is fixedly connected to the top side of the fixing plate 14.

[0023] In this embodiment, a protrusion 21 is installed on the top side of the fixing plate 14, and a magnetic block 22 is fixed on the top side of the protrusion 21. A magnetic block 23 is designed on one side of the magnetic block 22 and is located on one side of the locking arm 16. When the locking arm 16 is not rotating, the magnetic block 22 and the magnetic block 23 are in an adsorption state, thus initially positioning and fixing the locking arm 16. This prevents the locking arm 16 from shaking when not in use. When in use, only a rotational force greater than the magnetic adsorption force needs to be applied to easily separate the magnetic block 22 and the magnetic block 23, causing the locking arm 16 to rotate towards the connecting plate 13. After the locking arm 16 is disengaged from the connecting plate 13, the magnetic block 22 and the magnetic block 23 are re-adsorbed to fix the locking arm 16 again, thus avoiding interference with maintenance work caused by the shaking of the locking arm 16.

[0024] Working principle: like Figures 1-4As shown, firstly, by engaging the two-position five-way solenoid valve body 11 with the solenoid valve cover 12, the connecting plate 13 automatically contacts one side of the two-position five-way solenoid valve body 11. Then, the locking arm 16 is rotated 180 degrees, causing it to enter the recess of the connecting plate 13. After entering, the two inclined surfaces will contact each other. At this point, pressure is applied to the locking arm 16, using the pushing force of the inclined surface of the locking arm 16 to create a lateral force on the connecting plate 13, thereby ensuring a tight lock-locked connection between the solenoid valve cover 12 and the two-position five-way solenoid valve body 11. When the locking arm 16 is about to engage with the connecting plate... When contact 13 occurs, and the hole on the locking arm 16 aligns with the axis of the positioning rod 17, the elastic potential energy of the spring 110 is released instantaneously, pushing the sub-rod 18 to drive the positioning rod 17 to quickly embed into the hole of the locking arm 16, forming an automatic locking mechanism to fix the position of the locking arm 16 after rotation. This method also provides convenience for unlocking operations during subsequent maintenance. Simply push the positioning rod 17 to disengage it from the locking arm 16, and then rotate the locking arm 16 in the opposite direction to release the lateral pressure, thereby quickly disconnecting the structural connection between the solenoid valve cover 12 and the two-position five-way solenoid valve body 11. When the locking arm 16 is not rotating, magnetic block 12 and magnetic block 23 are in an attracted state, thus initially positioning and fixing the locking arm 16. This prevents the locking arm 16 from shaking when not in use. When in use, only a rotational force greater than the attraction force of the magnetic blocks needs to be applied to easily separate magnetic block 12 and magnetic block 23, causing the locking arm 16 to rotate towards the connecting plate 13. This method of fixing the locking arm 16 can prevent the shaking of the locking arm 16 from interfering with maintenance work.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
