[0027] When the electronic module is installed on the guide rail 4, as shown in Figure 4 , the electronic module is pressed downwards in the direction of the right arrow, the guide rail 4 enters the guide rail avoiding slot 11 on the side wall of the insulating shell 1, when pressed to the bottom, the two side flanges 41 of the guide rail 4 are respectively inserted into the guide rail insertion slot 211 and the groove 231 of the eccentric hook body, so as to realize the connection between the electronic module and the guide rail 4;

[0028] When the electronic module needs to be taken out of the guide rail 4, the upward pulling operation of the handle 24 drives the sliding body 21 of the operating rod 2 to slide against the elastic force of the elastic member 3 in the unlocking direction, the other end of the sliding body 21 retracts towards the inside of the insulating shell 1, at the same time, the guide rail insertion slot 211 at the other end of the sliding body 21 is separated from the side flange 41 of the guide rail 4, and at the same time, due to the sliding of the sliding body 21 in the unlocking direction, the pulling arm 22 drives the hook 23 to rotate, and then the eccentric hook body on the hook 23 is turned by a certain angle, and the flange 41 on the other side of the guide rail 4 is withdrawn from the groove 231 of the eccentric hook body, at this time, the flanges 41 on both sides of the guide rail 4 are separated from the guide rail insertion slot 211 and the groove 231 of the eccentric hook body respectively, and the electronic module can be smoothly taken off the guide rail 4.

[0029] The above structure makes it unnecessary to use additional tools when the electronic module is installed or disassembled, and it can be achieved by pulling the handle 24 of the operating rod 2, which is simple in structure and convenient to operate, and avoids the dependence on hardware tools.

[0030] A first guide inclined surface 212 in the shape of a chamfer is formed on the end face of the other end of the sliding body 21, and a second guide inclined surface 232 is formed on the outer side of the groove 231 of the eccentric hook body, and the first guide inclined surface 212 and the second guide inclined surface 232 form a trumpet structure for the insertion of the guide rail 4, and the flanges 41 on both sides of the guide rail 4 can slide into the guide rail insertion slot 211 and the groove 231 of the eccentric hook body along the first guide inclined surface 212 and the second guide inclined surface 232 respectively.

[0031] When the electronic module is installed on the guide rail 4, after the guide rail 4 enters the guide rail avoiding slot 11 on the side wall of the insulating shell 1, the electronic module is continuously pressed down, the flanges 41 on both sides of the guide rail 4 are in contact with the first guide inclined surface 212 and the second guide inclined surface 232 respectively, and when the first guide inclined surface 212 and the second guide inclined surface 232 are pressed, the first guide inclined surface 212 will move upwards to avoid (as shown in Figure 5 The second guide inclined surface 232 will rotate around the rotating shaft of the hook 23 to open, and then the flanges 41 on both sides of the guide rail 4 will smoothly slide to the bottom of the guide rail avoiding slot 11 and be opposite to the guide rail insertion slot 211 and the groove 231 of the eccentric hook body, and then the first guide inclined surface 212 and the second guide inclined surface 232 are reset under the elastic force of the elastic member 3, so that the flanges 41 on both sides of the guide rail 4 are smoothly clamped into the guide rail insertion slot 211 and the groove 231 of the eccentric hook body, which facilitates the smooth installation of the electronic module on the guide rail 4 and avoids interference.

[0032] A bending elastic arm 221 is formed on the pulling arm 22, and the elastic arm 221 can be elastically deformed under external force to enable the hook 23 to be elastically rotated within a certain range.

[0033] When the electronic module is installed on the guide rail 4, the flange 41 of the guide rail 4 extrudes the second guide slope 232 of the hook 23, and the hook 23 rotates around its rotating shaft to open the eccentric hook body. In this process, the elastic arm 221 on the traction arm 22 is bent and deformed, so that the guide rail slot 211 of the operating lever 2 and the eccentric hook body can be opened at the same time. When the guide rail slot 211 and the eccentric hook body are retracted and opened to a certain stroke, that is, the guide rail 4 is just completely clamped between the guide rail slot 211 and the eccentric hook body, and then force is pressed downward, a click sound is heard, which indicates that the product has been completely fixed on the guide rail 4 (as shown in Figure 6 At the same time, the flange 41 of the guide rail 4 is pressed on the elastic arm 221 of the operating lever 2. In this process, the force of the elastic member 3 always acts on the operating lever 2, so that the operating lever 2 always maintains a closed and locked state without external force.

[0034] The sliding body 21 side wall is also elastically movable and is provided with a rail removal actuating arm 25. The rail removal actuating arm 25 is away from the guide rail avoiding slot 11 in a natural state. The operating lever containing cavity inside wall of the insulating shell 1 is provided with an actuating member 14. When the sliding body 21 slides towards the unlocking direction, the actuating member 14 can actuate the rail removal actuating arm 25 to overcome its own elasticity and move towards the opening direction of the guide rail avoiding slot 11, and then tightly abuts against one side flange 41 of the guide rail 4, forcing the two side flanges 41 of the guide rail 4 to completely separate from the guide rail slot 211 and the groove 231 of the eccentric hook body and move a distance towards the opening direction of the guide rail avoiding slot 11.

[0035] When the electronic module needs to be removed from the guide rail 4, the handle 24 on the operating lever 2 is pulled, and the sliding body 21 of the operating lever 2 slides synchronously with the movement of the rail removal actuating arm 25. When the rail removal actuating arm 25 moves with the sliding body 21, the actuating member 14 on the inside wall of the operating lever containing cavity of the insulating shell 1 actuates the rail removal actuating arm 25 to overcome its own elasticity and move towards the opening direction of the guide rail avoiding slot 11, and then tightly abuts against one side flange 41 of the guide rail 4, so that the guide rail 4 moves a distance towards the opening direction of the guide rail avoiding slot 11. After the handle 24 of the operating lever 2 is released, the two side flanges 41 of the guide rail 4 will not enter the guide rail slot 211 and the groove 231 of the eccentric hook body again, and the flange 41 will smoothly remove the electronic module from the guide rail 4.

[0036] The rail removal actuating arm 25 is provided with a guide rail bent edge abutting surface 251. When the rail removal actuating arm 25 slides towards the opening direction of the guide rail avoiding slot 11 against its own elasticity, the guide rail bent edge abutting surface 251 on it gradually abuts against one side bent edge end surface of the guide rail 4, and at the same time forces the other side bent edge end surface of the guide rail 4 to tightly abut against the inside surface of the guide rail avoiding slot 11, and then clamps the two side bent edges of the guide rail 4 through the guide rail bent edge abutting surface 251 and the inside surface of the guide rail avoiding slot 11.

[0037] When the electronic module is taken out, pull up the handle 24 of the operating lever 2. When it is pulled to a certain distance, a clicking sound will be heard. At the same time, the status of the product and the guide rail 4 will be as follows. Figure 7 As shown, after the rail derailing toggle arm 25 toggles the guide rail 4 toward the opening of the guide rail avoidance groove 11 for a distance, the bent edges on both sides of the guide rail 4 are clamped by the tightening surface 251 of the guide rail bent edge on the rail derailing toggle arm 25 and the inner surface of the guide rail avoidance groove 11. The entire electronic module is fixed on the guide rail 4 by the clamping force of the rail derailing toggle arm 25, and the guide rail slot 211 and the eccentric hook body of the operating lever 2 are in an open state. At this time, the product can be directly pulled out. In order to improve the elastic clamping of the bent edges on both sides of the guide rail 4 when clamped, it is convenient to pull out the electronic module smoothly.

[0038] The derailing toggle arm 25 is an elastic cantilever structure integrally formed on the side wall of the sliding body 21. The derailing toggle arm 25 can elastically swing along the depth direction of the guide rail avoidance groove 11. The toggle member 14 is a boss integrally formed on the inner side wall of the operating rod accommodating cavity of the insulating shell 1. The boss is formed with an inclined extrusion surface 141. The elastic cantilever structure side wall of the derailing toggle arm 25 is formed with an inclined pressure surface 252. When the derailing toggle arm 25 slides with the sliding body 21, the pressure surface 252 on it is always elastically in close contact with the extrusion surface 141. When the electronic module is taken out, pull up the handle 24 of the operating lever 2, and the status of the product and the guide rail 4 is as shown in FIG. Figure 7 As shown, the extrusion surface 141 of the boss on the inner side wall of the operating rod accommodating cavity of the insulating housing 1 is squeezed together with the pressure surface 252 of the derailing toggle arm 25, thereby driving the derailing toggle arm 25 to elastically swing and deform, thereby causing the free end of the derailing toggle arm 25 to move.

[0039] The boss of the toggle member 14 is further provided with a limit blocking surface 142, and the elastic cantilever structure of the derailing toggle arm 25 is further provided with a protruding blocking step 253. After the derailing toggle arm 25 moves to a set position in the locking direction along with the sliding body 21, the protruding blocking step 253 on the toggle member 14 stops on the limit blocking surface 142, thereby preventing the derailing toggle arm 25 and the sliding body 21 from continuing to slide in the locking direction. The limit blocking surface 142 blocks the protruding blocking step 253 on the derailing toggle arm 25, thereby limiting the sliding distance of the operating rod 2 and preventing the derailing toggle arm 25 from interfering with the installation of the guide rail 4.

[0040] The free end of the elastic cantilever structure of the derailing toggle arm 25 forms an L-shaped structure, one side of the L-shaped structure forms a pushing surface 254 for pushing the guide rail 4 to slide toward the opening direction of the rail avoidance groove, and the other side of the L-shaped structure forms a guide rail bent edge tightening surface 251.

[0041] The sliding main body 21 is provided with a long strip-shaped sliding guide groove 213, the operating lever accommodating cavity side wall of the insulating shell 1 is provided with a guide protrusion 15, the guide protrusion 15 can be inserted into the sliding guide groove 213 in a sliding manner, the elastic member 3 is a compression spring, the compression spring is inserted into the sliding guide groove 213, and the two ends of the compression spring are tightly abutted against the side wall of the sliding guide groove 213 and the side wall of the guide protrusion 15 respectively, thereby providing the sliding main body 21 with elastic retaining force in the direction of the upper lock. The guide protrusion 15 in the insulating shell 1 slides in the sliding guide groove 213 of the sliding main body 21, realizes the sliding guidance and sliding distance limitation of the sliding main body 21, simultaneously facilitates the installation of the compression spring, and in addition, the elastic member 3 can also be a tension spring or a spring sheet.

[0042] The sliding main body 21, the traction arm 22, the clamping hook 23 and the handle 24 of the operating lever 2 are in an integrated molding structure, the insulating body includes an upper shell 101 and a lower shell 102, the upper shell 101 and the lower shell 102 are respectively formed with an operating lever accommodating groove 104, the upper shell 101 and the lower shell 102 are butted and are fixed and positioned by buckle 103 buckling connection, and the operating lever accommodating grooves 104 on the upper shell 101 and the lower shell 102 are spliced to form an operating lever accommodating cavity.
