Description

Technical Field

[0001] This utility model is a snap ring type electromagnetic coil, belonging to the field of electromagnetic valve technology. Background Technology

[0002] Traditional two-position two-way solenoid valves, such as Figure 1 As shown, it mainly consists of a valve body, valve core, electromagnetic coil, and sealing components. It has the following problems: 1. The top of the coil is not seamless but has a hole, resulting in poor sealing performance; 2. Installation by means of a nut is relatively troublesome; 3. Nut installation will have gaps, which will cause vibration during operation, resulting in low practicality and room for further improvement. There is an urgent need for a snap ring type electromagnetic coil to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a snap ring type electromagnetic coil to solve the problems mentioned in the background technology. This utility model has a reasonable structure, good waterproof performance, simple and convenient installation, and vibration damping function, making it highly practical.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a snap-ring type electromagnetic coil, comprising an electromagnetic base, a connecting joint, a snap-ring, a fixing plate, a pilot slot, an electromagnetic coil, and a fixing seat. The connecting joint is provided on the outer side of the electromagnetic base, and a snap-ring is provided at the end of the electromagnetic base opposite to the connecting joint. A fixing plate is provided at the lower end of the snap-ring. A pilot slot is opened on the upper surface of the electromagnetic base, and an electromagnetic coil is provided on the lower surface of the electromagnetic base. A fixing seat is provided at the lower end of the electromagnetic coil.

[0005] Furthermore, a limiting clamp is provided at the upper end of the retaining spring, and the limiting clamp slides tightly along the inner wall of the pilot groove.

[0006] Furthermore, the retaining spring, the limiting clamp, and the fixing clamp are collectively arranged in a U-shape.

[0007] Furthermore, a limiting groove is formed inside the pilot slot, and the limiting clamp plate engages with the limiting groove.

[0008] Furthermore, a coil slot is provided on the outer side of the fixed base, and the electromagnetic coil is inserted into the electromagnetic base.

[0009] Furthermore, the inner side of the fixing plate is provided with a clamping groove, and the fixing plate engages with the coil slot through the clamping groove.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a snap-fit ​​electromagnetic coil. Because it adds a snap-fit ​​piece, a limiting clamp, a fixing clamp, a fixing base, and a coil slot, the user first inserts the electromagnetic coil into the electromagnetic base from the bottom until the upper surface of the fixing base abuts against the lower end of the electromagnetic base. Then, the snap-fit ​​piece is removed, and the upper limiting clamp is slid inward along the pilot slot, so that the lower fixing clamp is clamped in the coil slot of the fixing base through the clamping groove, thereby fixing the position between the snap-fit ​​piece and the fixing base. Finally, the upper limiting clamp is clamped into the limiting groove, completing the fixed installation of the fixing base and the electromagnetic base. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-6This utility model provides a technical solution: a snap-ring type electromagnetic coil 8, including an electromagnetic base 1, a connecting joint 2, a snap-ring 3, a fixing plate 5, a pilot slot 6, an electromagnetic coil 8, and a fixing seat 9. The connecting joint 2 is provided on the outer side of the electromagnetic base 1, and the snap-ring 3 is provided at the end of the electromagnetic base 1 that is relatively away from the connecting joint 2. The fixing plate 5 is provided at the lower end of the snap-ring 3. The pilot slot 6 is opened on the upper end surface of the electromagnetic base 1, and the electromagnetic coil 8 is provided on the lower end surface of the electromagnetic base 1. The fixing seat 9 is provided at the lower end of the electromagnetic coil 8. This design solves the problems of poor waterproof performance and inconvenient installation of the original electromagnetic valve.

[0021] As the first embodiment of this utility model: a limiting clamping plate 4 is provided at the upper end of the snap ring 3. The limiting clamping plate 4 slides tightly along the inner wall of the pilot groove 6. The pilot groove 6 can guide and position the limiting clamping plate 4, thereby facilitating the installation of the snap ring 3 by the user. The snap ring 3, the limiting clamping plate 4, and the fixing clamping plate 5 are in the shape of a door. This design facilitates the engagement and installation of the electromagnetic base 1 and the electromagnetic coil 8. A limiting groove 7 is opened inside the pilot groove 6, and the limiting clamping plate 4 and the limiting groove 7 are interlocked. The limiting groove 7 can limit the limiting clamp 4, so that the limiting clamp 4 will not detach from the limiting groove 7 without external force. The outer side of the fixing base 9 is provided with a coil slot 91, and the electromagnetic coil 8 is inserted into the electromagnetic base 1. The inner side of the fixing clamp 5 is provided with a clamping groove 51, and the fixing clamp 5 is engaged with the coil slot 91 through the clamping groove 51. The coil slot 91 and the clamping groove 51 facilitate the fixing clamp 5 to engage and fix the fixing base 9, thereby fixing the position of the fixing base 9 and the electromagnetic base 1.

[0022] As a second embodiment of this utility model: When installing, the user first inserts the electromagnetic coil 8 into the electromagnetic base 1 from the bottom until the upper surface of the fixed base 9 abuts against the lower end of the electromagnetic base 1. Then, the snap ring 3 is removed, and its upper limiting clamp 4 is slid inward along the pilot groove 6, and its lower fixing clamp 5 is clamped in the coil groove 91 of the fixed base 9 through the clamping groove 51, thereby fixing the position between the snap ring 3 and the fixed base 9. Then, the upper limiting clamp 4 is inserted into the limiting groove 7 to complete the fixed installation of the fixed base 9 and the electromagnetic base 1. Compared with the traditional nut installation, the installation method of this design is simple and convenient, and there is no hole at the top, thereby improving the sealing and waterproof performance. After the snap ring 3 is inserted into the pilot groove 6 and the coil groove 91, it can be firmly fixed to prevent vibration, which is highly practical.
