Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description is provided for the specific embodiments of the present invention.
As shown in fig. 1 and fig. 2, a structure diagram of a device for preventing a relay from being touched by mistake according to an embodiment of the present invention includes: the electromagnetic coil fixing device comprises a base 1 and is characterized in that a shell 2 is fixedly installed on the top surface of the base 1, an electromagnetic coil 3 is fixedly installed above the base 1, a fixing rod 4 is fixedly installed above the base 1, the fixing rod 4 is hinged with a horizontal rod 5, the bottom of one end of the horizontal rod 5 is fixedly connected with a first spring 6, the other end of the first spring 6 is fixedly connected with the base 1, an armature 7 is fixedly installed at the bottom of the other end of the horizontal rod 5, and the armature 7 is located right above the electromagnetic coil 3; a button 8 is mounted on the side wall of the shell 2, the button 8 is in circuit connection with the electromagnetic coil 3, a through hole 9 is formed in the side wall of the shell 2, a blocking device 10 is mounted inside the through hole 9, the blocking device 10 comprises a guide sleeve 101, the guide sleeve 101 is fixedly connected with the inner wall of the top of the shell 2, a connecting rod 102 is arranged in the guide sleeve 101, two auxiliary blocks 103 are fixedly mounted on the side of the connecting rod 102, a second spring 104 is mounted on the side of each auxiliary block 103, and the other end of the second spring 104 is fixedly connected with the side wall of the shell 2; connecting rod 102 one end is passed through-hole 9, connecting rod 102 other end bottom fixed mounting has L type pole 105, the L type pole 105 other end articulates there is first connecting rod 106, pin 107 is installed to first connecting rod 106 one end, the first connecting rod 106 other end articulates there is second connecting rod 108, the second connecting rod 108 other end articulates there is fixed station 109, fixed station 109 and casing 2 top inner wall fixed connection.
When the relay is used, if the button 8 is touched by mistake, the electromagnetic coil 3 is electrified to generate suction to the armature 7, so that the armature 7 moves downwards, the armature 7 is fixedly connected with the horizontal rod 5, the armature 7 cannot move downwards under the obstruction of the obstruction device 10, the armature 7 cannot contact with the electromagnetic coil 3, and the effect of preventing the wrong touch is achieved.
During the use, if the button 8 is touched to the mistake, because the pin 107 keeps off in the below of horizon bar 5, make armature 7 and solenoid 3 unable contact, if need use the relay, press connecting rod 102 to casing 2 inside, then L type pole 105 can move right along with it, L type pole 105 can drive first connecting rod 106 motion, under the effect of second connecting rod 108, anticlockwise circular motion can be done to first connecting rod 106, and then drive pin 107 motion, make pin 107 leave original position, press button 8 again this moment, then armature 7 and solenoid 3 can normal contact.
In this embodiment, the length of the second spring 104 stretched by the pulling force should be greater than the length of the second spring 104 stretched naturally, so as to ensure that the whole blocking device 10 can be reset under the action of the second spring 104 after the connecting rod 102 is pressed down, so that the blocking rod 107 continues to block the movement of the horizontal rod 5.
In the embodiment, after the electromagnetic coil 3 is electrified, the attraction force to the armature 7 is greater than the pulling force of the first spring 6, so that after the electromagnetic coil 3 is electrified, the attraction force generated by the electromagnetic coil 3 to the armature 7 can overcome the pulling force of the first spring 6 to the armature 7, and the armature 7 can be moved smoothly.
In this embodiment, 2 inner walls of casing are provided with dry layer 11, and dry layer 11 can effectively completely cut off outside moisture, avoids the relay inside to wet, and then causes the short circuit scheduling problem of circuit, increases the relay life-span.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
