Specific embodiments

[0023] The following further describes the embodiments of the present utility model with reference to the accompanying drawings.

[0024] See the attached Figures 1-5 , in order to achieve the above technical features, the object of the present utility model is achieved as follows:

[0025] A relay that is easy to disassemble, comprising a main body 1. An installation groove 1a adapted to a slide rail 7 is provided on the back of the main body 1. A first locking tooth 1b for engaging with the slide rail 7 is provided at the top of the installation groove 1a. A chute 1c communicating with the installation groove 1a is centrally opened at the bottom end of the installation groove 1a. A locking component 2 is provided in the chute 1c, and pushing components 3 are movably installed on both sides of the chute 1c. The locking component 2 includes a U-shaped positioning seat 2a provided on the chute 1c, and a sliding seat 2b slidably installed on the outside of the U-shaped positioning seat 2a. An elastic reset member abutting against the U-shaped positioning seat 2b is centrally provided in the sliding seat 2b. A second locking tooth 2c extending into the installation groove 1a is provided at the top of the U-shaped positioning seat 2b. The second locking tooth 2c cooperates with the first locking tooth 1b to form a locking structure between the main body 1 and the slide rail. Wedge-shaped portions 2d slidably provided in the chute 1c are constructed on both sides of the sliding seat 2b. The pushing components 3 cooperate with the wedge-shaped portions 2d to push the sliding seat 2b and the second locking tooth 2c as a whole downward. The buckling of the main body 1 on the slide rail 7 is realized through the locking component 2 and the two pushing components 3. During installation, the first locking tooth 1b is hung on the top of the slide rail 7, and the sliding seat 2b provided with the second locking tooth 2c is squeezed under the slide rail 7 to cooperate with the first locking tooth 1b to fixedly arrange the main body 1 on the slide rail 7. When quick disassembly is required, by pressing one or two pushing components 3, the pushing components 3 push the sliding seat 2b having two wedge-shaped portions 2d to move downward in the chute 1c, and push the elastic reset member to contract, so that the second locking tooth 2c on the sliding seat 2b retracts into the chute 1c, thereby releasing the connection between the second locking tooth 2c and the slide rail 7, and the main body 1 can be removed from the slide rail 7. By pressing one or two pushing components 3, the setting of the main body of the relay on the slide rail 7 is released. In complex electrical configuration operations, the staff can achieve quick disassembly and assembly with one hand, making the replacement and maintenance of the relay module time-saving and labor-saving, meeting the requirements of modern industrial production for high efficiency and flexibility, and realizing the quick replacement and function expansion of electrical equipment.

[0026] Further, the pushing component 3 includes a pressure receiving plate 3a and a pushing tooth 3b. The pushing tooth 3b is provided at one end of the pressure receiving plate 3a, and the pushing tooth 3b is slidably installed in the chute 1c. An inclined surface 3c cooperating with the wedge-shaped portion 2d is provided on one side of the pushing tooth 3b. By pressing the pressure receiving plate 3a, the pushing tooth 3b is driven to push the sliding seat 2b and the second locking tooth 2c as a whole downward.

[0027] Further, a plurality of circular grooves are provided on the inclined surface of the wedge-shaped portion 2d, and rollers 2f are rotatably installed in the circular grooves. A rolling groove 3d cooperating with the rollers 2f is provided on the inclined surface 3c of the pushing tooth 3b. Through the arrangement of the rollers 2f, the friction force when the inclined surface 3c of the pushing tooth 3b and the wedge-shaped portion 2d slide relative to each other is reduced, so as to improve the smoothness of quick disassembly and assembly.

[0028] Furthermore, a guide cylinder 3e is provided on the side of the pressure plate 3a facing the main body 1, and a groove adapted to the pressure plate 3a is provided on the side of the main body 1, and a cavity 1d is provided in the groove. The two ends of the first spring 3f are respectively fixedly installed in the cavity 1d and the guide cylinder 3e. Through the setting of the first spring 3f, the pushing tooth 3b can be reset when the pressure plate 3a is no longer pressed.

[0029] Furthermore, the elastic return member includes a second spring 4 which is sleeved on the outside of the guide rod 2g, and the two ends of the second spring 4 are respectively abutted against the sliding seat 2b and the U-shaped positioning seat 2a. The guide rod 2g is arranged in the sliding seat 2b, and one end of the guide rod 2g passes through the U-shaped positioning seat 2a. The length extension direction of the guide rod 2g is consistent with the sliding direction of the sliding seat 2b. When the pressure plate 3a is pressed, the sliding seat 2b moves downward and compresses the second spring 4, thereby allowing the second spring 4 to store elastic force. After the pressure on the pressure plate 3a disappears, the sliding seat 2b is pushed upward under the action of the elastic force of the second spring 4, thereby causing the second latch tooth 2c to move into the mounting groove 1a.

[0030] Furthermore, guide keys 2h are constructed on both sides of the sliding seat 2b facing the main body 1, and positioning grooves that slidably cooperate with the guide keys 2h are opened on both sides of the sliding groove 1c to limit the sliding seat 2b.

[0031] Furthermore, a coil body 5 is inserted and arranged on one side of the main body 1, and a clamp 6 is movably mounted on the main body 1 and clamped on the outside of the coil body 5. By bending the clamp 6 and rotating it, the clamp 6 can be separated from the main body 1 of the relay, and then the coil body 5 arranged on the main body 1 can be removed, making it easier to disassemble the relay coil body.

[0032] Working principle: by hanging the first latch tooth 1b in the mounting groove 1a on the main body 1 on the slide rail 7, and making the U-shaped positioning seat 2a press against the bottom of the slide rail 7, the main body 1 is snapped on the slide rail 7. When disassembly and assembly are required, one or two pressure plates 3a can be pressed, and the pressure plates 3a can push the several second springs 4 arranged in the guide cylinder 3e to contract, so as to drive the sliding seat 2b to move downward, and several rollers 2f can roll in the rolling groove 3d to reduce the friction force when the inclined surface 3c of the pushing tooth 3b and the wedge-shaped portion 2d slide relative to each other. When the sliding seat 2b moves downward, the guide key 2h cooperates with the guide rod 2g to guide the stability of the sliding seat 2b moving downward, and the second spring 4 helps the sliding seat 2b to reset, and the coil body 5 arranged on the main body 1 of the relay can be removed by turning the clamp 6, which is convenient to use.
