[0003] In order to overcome the above defects, the present invention provides an electronic module fixing structure, which effectively improves the convenience of loading and unloading the electronic module body and the guide rail, is more flexible, and greatly improves the on-site operation efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an electronic module fixing structure, including an insulating shell, an operating rod and an elastic member, an operating rod accommodating cavity is provided on the inner side of the insulating shell, a guide rail avoidance groove for accommodating the guide rail is formed on the side wall of the insulating shell, and left and right openings respectively connected to the operating rod accommodating cavity are provided on the two side walls of the guide rail avoidance groove, the operating rod includes a sliding body, a traction arm, a hook and a handle, the handle is fixedly arranged at one end of the sliding body, and one end of the traction arm is fixedly arranged at the other end of the sliding body, the sliding body and the traction arm of the operating rod are accommodated in the operating rod accommodating cavity in the insulating shell, the handle of the operating rod extends out of the outside of the insulating body, and pulling the handle can drive the sliding body to slide in the operating rod accommodating cavity, and the end surface of the other end of the sliding body is also A concave guide rail slot is provided, and the guide rail slot is exposed in the guide rail avoidance groove through the left opening on the insulating shell. The other end of the traction arm is connected to the hook, and the hook can be rotatably installed in the operating rod accommodating cavity of the insulating body. An eccentric hook body is provided on the hook, and the eccentric hook body can be exposed in the guide rail avoidance groove through the right opening on the insulating shell. The flanges on both sides of the guide rail can be slidably inserted in the grooves of the guide rail slot and the eccentric hook body respectively. The sliding body slides in the unlocking direction to make the guide rail slot slide and pull the hook to rotate through the traction arm, so that the guide rail slot and the eccentric hook body synchronously release the flanges on both sides of the guide rail. The elastic member provides an elastic retaining force to the sliding body of the operating rod in the locking direction, so that the eccentric hook body and the guide rail slot are directly clamped by the flanges on both sides of the guide rail.

[0005] As a further improvement of the present invention, a chamfered first guide slope is formed on the end face of the other end of the sliding body, an inclined second guide slope is formed on the outer side of the groove of the eccentric hook body, and a bell-mouth structure for inserting the guide rail is formed between the first guide slope and the second guide slope, and the flanges on both sides of the guide rail can slide into the guide rail slot and the groove of the eccentric hook body along the first guide slope and the second guide slope respectively.

[0006] As a further improvement of the present invention, a bent elastic arm is formed on the traction arm, and the elastic arm can be elastically deformed under the action of external force so that the hook can be elastically rotated within a certain range.

[0007] As a further improvement of the present invention, a rail-retracting toggle arm is provided on the side wall of the sliding body so as to be able to move elastically. The rail-retracting toggle arm is away from the guide rail avoidance groove in a natural state. A toggle member is provided on the inner side wall of the operating rod accommodating cavity of the insulating shell. When the sliding body slides toward the unlocking direction, the toggle member can toggle the rail-retracting toggle arm to overcome its own elasticity and move toward the opening direction of the guide rail avoidance groove and then press against the flange on one side of the guide rail, forcing the flanges on both sides of the guide rail to completely disengage from the guide rail slot and the groove of the eccentric hook body and move a distance toward the opening direction of the guide rail avoidance groove.

[0008] As a further improvement of the present invention, a guide rail bent edge tightening surface is provided on the guide derailing toggle arm. When the guide derailing toggle arm overcomes its own elasticity and slides toward the opening direction of the guide rail avoidance groove, the guide rail bent edge tightening surface on it gradually presses against the bent edge end face on one side of the guide rail, and at the same time forces the bent edge end face on the other side of the guide rail to be tightly attached to the inner surface of the guide rail avoidance groove, thereby clamping the bent edges on both sides of the guide rail through the guide rail bent edge tightening surface and the inner surface of the guide rail avoidance groove.

[0009] As a further improvement of the present invention, the derailing toggle arm is an elastic cantilever structure integrally formed on the side wall of the sliding body, and the derailing toggle arm can elastically swing along the depth direction of the guide rail avoidance groove.

[0010] As a further improvement of the present invention, a limit blocking surface is also provided on the boss of the toggle member, and an outward convex blocking step is also provided on the elastic cantilever structure of the derailing toggle arm. After the derailing toggle arm moves to a set position in the locking direction as the sliding body does, the outward convex blocking step thereon stops on the limit blocking surface of the toggle member, thereby preventing the derailing toggle arm and the sliding body from continuing to slide in the locking direction.

[0011] As a further improvement of the present invention, the free end of the elastic cantilever structure of the derailing toggle arm forms an L-shaped structure, one side of the L-shaped structure forms a pushing surface for pushing the guide rail to slide toward the opening direction of the rail avoidance groove, and the other side of the L-shaped structure forms a tightening surface of the bent edge of the guide rail.

[0012] As a further improvement of the present invention, an elongated sliding guide groove is provided on the sliding main body, and a guide protrusion is provided on the side wall of the operating rod accommodating cavity of the insulating shell. The guide protrusion can be relatively slidably inserted in the sliding guide groove. The elastic member is a compression spring, and the compression spring is inserted and accommodated in the sliding guide groove. The two ends of the compression spring are respectively tightly pressed against the side walls of the sliding guide groove and the side walls of the guide protrusion, thereby providing the sliding main body with an elastic retaining force in the locking direction.

[0013] As a further improvement of the present invention, the sliding body, traction arm, hook and handle of the operating rod are an integrally formed structure, the insulating body includes an upper shell and a lower shell, the upper shell and the lower shell are respectively formed with an operating rod accommodating groove, the upper shell and the lower shell are butted and fixed in position by a snap-fit ​​connection, and the operating rod accommodating grooves on the upper shell and the lower shell are spliced ​​to form an operating rod accommodating cavity.

[0014] The beneficial effects of the present invention are as follows: the present invention forms a guide rail slot and an eccentric hook body on the operating rod through an installation operating rod that can elastically slide in an insulating body, and the sliding body of the operating rod is pulled by a handle to overcome the elastic force to slide, thereby making the guide rail slot and the eccentric hook body synchronously linked, so that the flange structures on both sides of the guide rail simultaneously withdraw from the guide rail slot and the groove of the eccentric hook body. During operation, when the present invention is fixed on the guide rail, it is only necessary to press down hard to hear a clicking sound, indicating that the installation is in place. When taking it out, it is only necessary to pull the handle of the operating rod to make the operating rod slide, and stop pulling when a clicking sound is heard, so that the electronic module can be taken out. After taking out the electronic module, release the handle, and the operating rod will immediately return to its original position under the action of the elastic member. Compared with the traditional structure, which still needs to toggle the operating rod to return to its original position, the operation of the present invention is simpler and more convenient. In addition, the present invention enables the electronic module to be installed and disassembled on the guide rail without the aid of tools, thus avoiding dependence on tools and being easy to operate in any occasion.

[0026] Embodiment: An electronic module fixing structure comprises an insulating shell 1, an operating rod 2 and an elastic member 3, wherein an operating rod accommodating cavity is provided on the inner side of the insulating shell 1, a guide rail avoidance groove 11 for accommodating a guide rail 4 is formed on the side wall of the insulating shell 1, and a left opening 12 and a right opening 13 which are respectively connected to the operating rod accommodating cavity are provided on the two side walls of the guide rail avoidance groove 11, the operating rod 2 comprises a sliding body 21, a traction arm 22, a hook 23 and a handle 24, the handle 24 is fixedly arranged at one end of the sliding body 21, and one end of the traction arm 22 is fixedly arranged at the other end of the sliding body 21, the sliding body 21 and the traction arm 22 of the operating rod 2 are accommodated in the operating rod accommodating cavity in the insulating shell 1, the handle 24 of the operating rod 2 extends out of the outside of the insulating body, and pulling the handle 24 can drive the sliding body 21 to slide in the operating rod accommodating cavity, and a concave guide rail slot 211 is also provided on the end surface of the other end of the sliding body 21, The guide rail slot 211 is exposed in the guide rail avoidance groove 11 through the left opening 12 on the insulating shell 1, and the other end of the traction arm 22 is connected to the hook 23, and the hook 23 can be rotatably installed in the operating rod accommodating cavity of the insulating body. An eccentric hook body is provided on the hook 23, and the eccentric hook body can be exposed in the guide rail avoidance groove 11 through the right opening 13 on the insulating shell 1, and the flanges 41 on both sides of the guide rail 4 can be slidably inserted in the guide rail slot 211 and the grooves 231 of the eccentric hook body respectively. The sliding body 21 slides in the unlocking direction to make the guide rail slot 211 slide and pull the hook 23 to rotate through the traction arm 22, so that the guide rail slot 211 and the eccentric hook body synchronously release the flanges 41 on both sides of the guide rail 4, and the elastic member 3 provides the sliding body 21 of the operating rod 2 with an elastic retaining force in the locking direction, so that the eccentric hook body and the guide rail slot 211 directly clamp the flanges 41 on both sides of the guide rail 4.

[0027] When installing the electronic module on rail 4, Figure 4 As shown, the electronic module is pressed down in the direction of the arrow on the right side, and the guide rail 4 enters the guide rail avoidance groove 11 on the side wall of the insulating housing 1. After being pressed down to the bottom, the flanges 41 on both sides of the guide rail 4 are respectively inserted into the guide rail slot 211 and the groove 231 of the eccentric hook body, thereby realizing the connection between the electronic module and the guide rail 4;

[0028] When the electronic module needs to be removed from the guide rail 4, the handle 24 is pulled upward to drive the sliding body 21 of the operating rod 2 to overcome the elastic force of the elastic member 3 and slide in the unlocking direction. While the other end of the sliding body 21 retracts toward the inside of the insulating shell 1, the guide rail slot 211 at the other end of the sliding body 21 disengages from the flange 41 on one side of the guide rail 4. At the same time, since the sliding body 21 slides toward the unlocking direction, the traction arm 22 drives the hook 23 to rotate, so that the eccentric hook body on the hook 23 flips a certain angle, and the flange 41 on the other side of the guide rail 4 withdraws from the groove 231 of the eccentric hook body. At this time, the flanges 41 on both sides of the guide rail 4 are respectively disengaged from the guide rail slot 211 and the groove 231 of the eccentric hook body, so that the electronic module can be smoothly removed from the guide rail 4.

[0029] The above structure does not require any additional tools when installing or removing the electronic module. It can be achieved by simply pulling the handle 24 of the operating rod 2. It has a simple structure and is easy to operate, avoiding dependence on hardware tools.

[0030] A chamfered first guide slope 212 is formed on the end face of the other end of the sliding body 21, and an inclined second guide slope 232 is formed on the outer side of the groove 231 of the eccentric hook body. A bell-mouth structure for inserting the guide rail 4 is formed between the first guide slope 212 and the second guide slope 232, and the flanges 41 on both sides of the guide rail 4 can slide into the guide rail slot 211 and the groove 231 of the eccentric hook body along the first guide slope 212 and the second guide slope 232 respectively.

[0031] When the electronic module is installed on the guide rail 4, after the guide rail 4 enters the guide rail avoidance groove 11 on the side wall of the insulating housing 1, the electronic module is continued to be pressed down, and the flanges 41 on both sides of the guide rail 4 are respectively in contact with the first guide slope 212 and the second guide slope 232. When the first guide slope 212 and the second guide slope 232 are squeezed, the first guide slope 212 will move upward to avoid (such as Figure 5 As shown in the figure, the second guide bevel 232 will rotate and open around the rotating shaft of the hook 23, so that the flanges 41 on both sides of the guide rail 4 can slide smoothly to the bottom of the guide rail avoidance groove 11 and face the guide rail slot 211 and the groove 231 of the eccentric hook body. Then, under the elastic force of the elastic member 3, the first guide bevel 212 and the second guide bevel 232 are reset, so that the flanges 41 on both sides of the guide rail 4 can be smoothly inserted into the guide rail slot 211 and the groove 231 of the eccentric hook body. This structure facilitates the smooth installation of the electronic module on the guide rail 4 and avoids interference.

[0032] The traction arm 22 is formed with a bent elastic arm 221 . The elastic arm 221 can be elastically deformed by an external force so that the hook 23 can 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 squeezes the second guide slope 232 of the hook 23, and the hook 23 rotates around its rotation axis to open the eccentric hook body. During this process, the elastic arm 221 on the traction arm 22 will bend and deform, so that the guide rail slot 211 and the eccentric hook body of the operating rod 2 can be opened at the same time. When the guide rail slot 211 and the eccentric hook body retreat and open to a certain stroke, the guide rail 4 is just completely stuck between the guide rail slot 211 and the eccentric hook body. At this time, if you press down hard again, you will hear a clicking sound, which means that the product has been completely fixed on the guide rail 4 (such as Figure 6 As shown), at the same time, the flange 41 of the guide rail 4 will also press on the elastic arm 221 of the operating rod 2. During this process, the force of the elastic member 3 always acts on the operating rod 2, so that the operating rod 2 can always remain in a closed and locked state when there is no external force.

[0034] The side wall of the sliding body 21 is also provided with a rail-retracting toggle arm 25 which can elastically move. The rail-retracting toggle arm 25 is away from the guide rail avoidance groove 11 in a natural state. A toggle member 14 is provided on the inner side wall of the operating rod accommodating cavity of the insulating shell 1. When the sliding body 21 slides toward the unlocking direction, the toggle member 14 can toggle the rail-retracting toggle arm 25 to overcome its own elasticity and move toward the opening direction of the guide rail avoidance groove 11 and then press against the flange 41 on one side of the guide rail 4, forcing the flanges 41 on both sides of the guide rail 4 to completely disengage from the guide rail slot 211 and the groove 231 of the eccentric hook body and move a distance toward the opening direction of the guide rail avoidance groove 11.

[0035] When the electronic module needs to be removed from the guide rail 4, the handle 24 on the operating rod 2 is pulled, and the sliding body 21 of the operating rod 2 slides while the track-removing toggle arm 25 moves synchronously. When the track-removing toggle arm 25 moves with the sliding body 21, the toggle piece 14 on the inner side wall of the operating rod accommodating cavity of the insulating shell 1 toggle the track-removing toggle arm 25 to overcome its own elasticity and move toward the opening direction of the guide rail avoidance groove 11 and then tightly abut against the flange 41 on one side of the guide rail 4, so that the guide rail 4 moves a distance toward the opening direction of the guide rail avoidance groove 11. After releasing the handle 24 of the operating rod 2, the flanges 41 on both sides of the guide rail 4 will no longer enter the guide rail slot 211 and the groove 231 of the eccentric hook body, and the flanges 41 successfully remove the electronic module from the guide rail 4.

[0036] The rail derailing toggle arm 25 is provided with a guide rail bent edge tightening surface 251. When the rail derailing toggle arm 25 overcomes its own elasticity and slides toward the opening direction of the guide rail avoidance groove 11, the guide rail bent edge tightening surface 251 thereon gradually presses against the bent edge end surface on one side of the guide rail 4, and at the same time forces the bent edge end surface on the other side of the guide rail 4 to be tightly attached to the inner surface of the guide rail avoidance groove 11, and then the bent edges on both sides of the guide rail 4 are clamped by the guide rail bent edge tightening surface 251 and the inner surface of the guide rail avoidance groove 11.

[0037] When the electronic module is taken out, the handle 24 of the operating rod 2 is pulled upwards. When it is pulled to a certain stroke, a clicking sound is heard. At the same time, the status of the product and the guide rail 4 is as follows. Figure 7 As shown, after the rail derailing arm 25 moves the guide rail 4 toward the opening direction 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 bent edges of the guide rail on the rail derailing 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 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 being 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 be elastically swung 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. An inclined extrusion surface 141 is formed on the boss. An inclined pressure surface 252 is formed on the side wall of the elastic cantilever structure of the derailing toggle arm 25. When the derailing toggle arm 25 slides with the sliding body 21, the pressure surface 252 thereon is always elastically close to the extrusion surface 141. When the electronic module is taken out, the handle 24 of the operating rod 2 is pulled upwards, and the state 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] A limit blocking surface 142 is also provided on the boss of the toggle member 14, and a convex blocking step 253 is also provided on the elastic cantilever structure of the derailing toggle arm 25. After the derailing toggle arm 25 moves to a set position in the locking direction along with the sliding body 21, the convex blocking step 253 on the derailing toggle arm 25 stops on the limit blocking surface 142 of the toggle member 14, thereby preventing the derailing toggle arm 25 and the sliding body 21 from continuing to slide in the locking direction. The convex blocking step 253 on the derailing toggle arm 25 is blocked by the limit blocking surface 142, so as to limit the sliding distance of the operating rod 2 and prevent 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 rail-retracting 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 body 21 is provided with a long strip sliding guide groove 213, and the side wall of the operating rod accommodating cavity of the insulating housing 1 is provided with a guide protrusion 15, and the guide protrusion 15 can be inserted in the sliding guide groove 213 so as to slide relatively. The elastic member 3 is a compression spring, and the compression spring is inserted and accommodated in the sliding guide groove 213. The two ends of the compression spring are respectively pressed against the side wall of the sliding guide groove 213 and the side wall of the guide protrusion 15, thereby providing the sliding body 21 with an elastic retaining force in the locking direction. The guide protrusion 15 in the insulating housing 1 slides in the sliding guide groove 213 of the sliding body 21, so as to realize the sliding guide and the limitation of the sliding distance of the sliding body 21, and also facilitate the installation of the compression spring. In addition, the elastic member 3 can also be a tension spring or a spring.

[0042] The sliding body 21, the traction arm 22, the hook 23 and the handle 24 of the operating rod 2 are an integrally formed 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 rod receiving groove 104, the upper shell 101 and the lower shell 102 are butted and fixedly positioned by snapping 103, and the operating rod receiving grooves 104 on the upper shell 101 and the lower shell 102 are spliced ​​to form an operating rod receiving cavity. The insulating body adopts a split structure to facilitate the installation of the operating rod 2, and the operating rod 2 adopts an integrally formed structure to facilitate production and assembly.
