[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0059] A U-shaped connecting frame 3, which is inserted into the U-shaped hanger 1 and is detachably connected to the U-shaped hanger 1, and a wiring rack 4 is fixedly installed on the bottom end of the U-shaped connecting frame 3;

[0060] and an assembly control mechanism, the assembly control mechanism is connected to the U-shaped hanger 1 and the U-shaped connecting frame 3 respectively, wherein the assembly control mechanism includes a guide positioning component and an automatic insertion component;

[0061] The guide positioning component is connected to the U-shaped hanger 1, the automatic insertion component is connected to the U-shaped connecting frame 3, and the automatic insertion component and the guide positioning component are detachably connected.

[0062] See also Figure 1-Figure 12 , further comprising: a card slot 13, wherein the card slot 13 is opened on the inner wall of the U-shaped hanger 1;

[0063] And a clamping protrusion 15 , which is arranged on the U-shaped connecting frame 3 and is detachably connected to the clamping slot 13 .

[0064] It also includes: a positioning hole 8, the number of the positioning holes 8 is multiple, and the multiple positioning holes 8 are evenly opened in the card slot 13;

[0065] and a plug post 7, wherein the number of the plug posts 7 is plural, the multiple plug posts 7 are evenly mounted on the clamping protrusion 15, and the plug posts 7 are detachably connected to the positioning socket 8;

[0066] The length of the plug post 7 is greater than the thickness of the U-shaped hanger 1 .

[0067] When installing the communication optical cables and network cables in the computer room, first, one of the U-shaped hangers 1 can be installed on the top of the computer room through the installation part 9 (at this time, since the wiring rack 4 has not been installed, and the weight of the U-shaped hanger 1 is light, it is convenient for the staff to take and install, and after one of the U-shaped hangers 1 is installed on the top of the computer room, the other U-shaped hanger 1 is directly inserted into the U-shaped connecting frame 3 before lifting the wiring rack 4). The installation method can be bolted, and then, through the provided guide positioning component, one set of automatic insertion components and the U-shaped connecting frame 3 can be moved in one of the U-shaped hangers 1. , and according to the height of the wiring rack 4 to be installed, after it is moved to the specified position in the U-shaped hanger 1 on the U-shaped connecting frame 3, one of the U-shaped connecting frames 3 on the wiring rack 4 can be mutually clamped with one of the U-shaped hangers 1 through the cooperation of the guiding positioning component and the automatic insertion component. At this time, under the pulling force of one pair of U-shaped hangers 1 and the U-shaped connecting frame 3, the staff can completely release the wiring rack 4 and install another U-shaped hanger 1 on the top of the machine room. At this time, the wiring rack 4 can be in a suspended state. After installing several U-shaped hangers 1 and wiring racks 4 on the top of the machine room in this way, when there is still space between adjacent wiring racks 4 When a transition frame is needed, it is only necessary to insert the two ends of the transition frame into the ends of the two wiring racks 4. Then, under the support of the wiring rack 4, the transition frame can be suspended without the need for external support. At this time, the staff can connect the wiring rack 4 with the transition frame by bolting, so that the installation of multiple wiring racks 4 can be easily completed. In addition, after the installation is completed, the wiring rack 4 cannot move horizontally under the limiting effect of the two U-shaped hangers 1. At the same time, the mutual insertion between the card slot 13 and the card-mounting protrusion 15 and the mutual insertion between the multiple plug posts 7 and the positioning sockets 8 can ensure that the wiring rack 4 is installed. Stability, and when one of the U-shaped hangers 1 or two U-shaped hangers 1 fall off due to damage, the U-shaped hanger 1 and the U-shaped connecting frame 3 can be quickly disengaged from each other through the cooperation of the guiding positioning component and the automatic plug-in component, and the damaged U-shaped hanger 1 can be removed and quickly replaced for avoiding the deformation of the entire wiring rack 4 due to excessive local gravity. The operation is simple and the probability of safety accidents in high-altitude installation operations is reduced. While ensuring the installation balance of the entire wiring rack 4, the firmness of the installation is guaranteed and it can be quickly disengaged in an emergency, which provides convenience for subsequent installation operations.

[0068] In one embodiment of the present invention, see Figure 1-Figure 12 , the guiding and positioning component comprises:

[0069] A movable through slot 16, wherein the movable through slot 16 is provided on the inner side wall of the U-shaped hanger 1;

[0070] A square positioning socket 2, wherein the number of the square positioning sockets 2 is multiple, and the multiple square positioning sockets 2 are evenly arranged on the U-shaped hanger 1, and the square positioning sockets 2 are also detachably connected to the automatic plug-in assembly;

[0071] And positioning notches 17, the number of the positioning notches 17 is equal to the number of the square positioning sockets 2, and all are opened on the U-shaped hanger 1, wherein a plurality of the square positioning sockets 2 are connected to the movable through groove 16 through a plurality of positioning notches 17 respectively.

[0072] The automatic insertion assembly comprises:

[0073] A disassembly control box 14, wherein the disassembly control box 14 is fixedly mounted on the U-shaped connecting frame 3, and two movable openings 20 are provided on the top of the disassembly control box 14, and an L-shaped plug rod 11 is inserted into each of the movable openings 20;

[0074] A limiting groove 19, which is provided in the disassembly and assembly control box 14 and is slidably connected to the L-shaped plug rod 11;

[0075] A return spring 21, wherein the number of the return springs 21 is two, wherein the two ends of the return spring 21 are fixedly connected to the L-shaped plug rod 11 and the disassembly control box 14 respectively, and the return spring 21 is located in the disassembly control box 14;

[0076] And a toggle head 18 , wherein the toggle head 18 is fixedly mounted on the L-shaped plug rod 11 .

[0077] See also Figure 1-Figure 12 , further comprising: a tightening protrusion 10, wherein the number of the tightening protrusions 10 is multiple, and the multiple tightening protrusions 10 are respectively located in the square positioning socket 2 arranged near the bottom end of the U-shaped hanger 1;

[0078] Furthermore, the tightening protrusion 10 is detachably connected to the L-shaped insertion rod 11 .

[0079] When the U-shaped hanger 1 and the U-shaped connecting frame 3 are mutually clamped, the two L-shaped rods 11 can slide in the limit groove 19 and the movable opening 20 at the same time by manually pulling the toggle head 18, and move toward the middle of the disassembly control box 14. At this time, the distance between the two L-shaped rods 11 is reduced, and the reset spring 21 is gradually in a compressed state. When the maximum distance between the two L-shaped rods 11 is less than the slot width of the U-shaped hanger 1, the L-shaped rod 11 can be clamped into the movable slot 16, and under the lifting and pushing action of the staff, the L-shaped rod 11 can slide upward in the movable slot 16 until it slides to the specified square positioning socket. 2 (wherein, each square positioning socket 2 can be marked with a number so that the staff can quickly and accurately insert multiple U-shaped connecting frames 3 into the specified height in the U-shaped hanger 1), at this time, a lateral thrust is applied to the U-shaped connecting frame 3 and the wiring rack 4, so that the L-shaped plug rod 11 can enter the square positioning socket 2 of the specified height through the positioning notch 17, and under the elastic force of the reset spring 21, the L-shaped plug rod 11 can be quickly inserted into the square positioning socket 2, thereby completing the installation of the U-shaped connecting frame 3 and the wiring rack 4. At the same time, under the action of the lateral thrust, the card-mounting protrusion 15 is inserted into the card slot 13, and the plug column 7 is inserted into the positioning plug The number of the plug posts 7 and the positioning sockets 8 are both multiple. According to the different heights at which the U-shaped connecting frame 3 is inserted into the U-shaped hanger 1, the number of the plug posts 7 inserted into the positioning sockets 8 is also different (at this time, as the height at which the U-shaped connecting frame 3 is inserted into the U-shaped hanger 1 is lower, fewer plug posts 7 will be inserted into the positioning sockets 8. In this state, the firmness of the installation of the wiring rack 4 is greatly reduced. At this time, through the tightening protrusion 10 in the square positioning socket 2 arranged near the bottom end of the U-shaped hanger 1, the tightening protrusion 10 can be in the form of rubber, which can form a certain anti-slip effect on the L-shaped plug rod 11, thereby ensuring that the L-shaped plug rod 1 1 and the square positioning socket 2 are firmly connected with each other, and the production cost and difficulty can be reduced). In addition, since the length of the plug post 7 is greater than the thickness of the U-shaped hanger 1, the plug post 7 will extend a distance after being inserted into the positioning socket 8. When the U-shaped hanger 1 and the U-shaped connecting frame 3 need to be disengaged from each other later, the plug post 7 is pushed by manpower while the toggle head 18 is pulled manually, thereby forming a lateral reverse thrust on the U-shaped connecting frame 3, so that the L-shaped plug rod 11 enters the movable through groove 16 through the positioning notch 17 again, thereby completing the disengagement between the U-shaped hanger 1 and the U-shaped connecting frame 3, which will not be described in detail here.

[0080] In one embodiment of the present invention, see Figure 1-Figure 12 , further comprising: a pressure detection portion 22, the pressure detection portion 22 being located on the bottom end of the L-shaped insertion rod 11 and abutting against the inner wall of the square positioning socket 2;

[0081] And an anti-slip control component, which is located in a chamber opened on the L-shaped insertion rod 11 and is electrically connected to the pressure detection part 22.

[0082] The anti-fall-off control component comprises:

[0083] A multifunctional smooth head 12, which is inserted into the cavity opened on the L-shaped insertion rod 11 and is slidably connected with the cavity, and a blocking flange 23 is fixedly installed on the end of the multifunctional smooth head 12, and the blocking flange 23 abuts against the convex portion provided in the cavity;

[0084] A magnetic plug 24, one end of which is fixedly connected to the blocking flange 23, and the other end of which is connected to a power device arranged in the chamber, and a placement opening 26 is also provided on the magnetic plug 24;

[0085] And a thin pull rope 25, one end of which is fixedly connected to the blocking flange 23, and the other end of which passes through the placement port 26 and is fixedly connected to the inner wall of the chamber.

[0086] Before the U-shaped hanger 1 and the U-shaped connecting frame 3 are connected to each other, under the action of the blocking flange 23 abutting against the convex part set in the chamber, one end of the multifunctional smooth head 12 can extend out of the chamber for a certain length. At this time, due to the smooth end of the multifunctional smooth head 12, the multifunctional smooth head 12 can slide smoothly in the moving groove 16 and the positioning notch 17. When the weight borne by the entire wiring rack 4 increases (which may be a normal phenomenon or an abnormal situation, for example, a U-shaped hanger 1 becomes loose due to a malfunction), at this time, the gravity borne by the wiring rack 4 increases, and the pressure borne by the pressure detection part 22 in contact with the square positioning socket 2 increases synchronously. Under the control of the pressure detection part 22, The power device can be put into operation, wherein the power device can be in the form of an electromagnet or a cylinder, which is not specifically limited here. When the power device is working, the multifunctional smooth head 12 can drive the magnetic plug 24 to slide outward under the action of magnetic repulsion or air pressure until the multifunctional smooth head 12 and the magnetic plug 24 are all extended out of the chamber. At this time, under the pulling action of the thin pull rope 25, the multifunctional smooth head 12 and the magnetic plug 24 will be suspended at the end position of the L-shaped plug rod 11, and because the weight of the multifunctional smooth head 12 is greater than the weight of the magnetic plug 24, at this time, the whole is in a vertical state with the multifunctional smooth head 12 at the bottom and the magnetic plug 24 at the top. Then, when the L-shaped plug rod When 11 is contracted by external force, even if the L-shaped plug rod 11 is separated from the square positioning socket 2, the long rod-shaped structure composed of the multifunctional smooth head 12 and the magnetic plug 24 will be stuck in the square positioning socket 2. Then, under the pulling force of the thin pull rope 25, the U-shaped hanger 1 and the U-shaped connecting frame 3 can be prevented from being separated, thereby ensuring the stability of the overall wiring rack 4 and avoiding the overall frame from falling and injuring the equipment in the machine room or related personnel under extreme conditions, thereby further ensuring the safety performance of the overall wiring rack 4. In addition, as the height of the U-shaped connecting frame 3 inserted into the U-shaped hanger 1 becomes lower, fewer plug posts 7 will be inserted into the positioning socket 8, and the wiring rack 4 is installed firmly in this state. It is greatly reduced. At this time, through the tightening protrusion 10 in the square positioning socket 2 arranged near the bottom end of the U-shaped hanger 1, the pressure value detected by the pressure detection part 22 can be greater than the pressure detection value when the pressure detection part 22 is located in other square positioning sockets 2, and the value detected by the pressure detection part 22 can be made closer to the critical value of the set action, so that it is easier to put the multifunctional smooth head 12 and the magnetic plug 24 into work, thereby further ensuring the firmness of the overall wiring rack 4. Of course, according to different usage scenarios, the pressure detection part 22 can also be powered off, so that the pressure detection part 22 will not be put into work under any pressure, thereby facilitating the rapid disengagement of the overall device. No more details will be given here.

[0087] In one embodiment of the present invention, see Figure 1-Figure 12, further comprising: a transfer protection box 5, the transfer protection box 5 is fixedly mounted on the wiring rack 4, and the transfer protection box 5 is also provided with a warning device 6;

[0094] And a bypass control column 32, the number of the bypass control columns 32 is multiple, and the multiple bypass control columns 32 are respectively connected to the power terminal 1 27 and the power terminal 2 33, and are detachably connected to the adapter protection box 5, and the bypass control column 32 is also electrically connected to the warning device 6.

[0095] When the cables laid on the wiring rack 4 are tightened due to external factors, in order to avoid the cables being broken or cracked, multiple adapter protection boxes 5 are respectively arranged on multiple wiring racks 4, and the ends of the cables are connected to the threaded terminal heads 31 by screw connections. When the cables are pulled, the connection head 27 is pulled to slide in the adapter protection box 5, and the elastic connecting piece 1 28 or the elastic connecting piece 2 29 or both are moved at the same time. When the pulling force is only instantaneous and the pulling force disappears instantaneously (this situation rarely occurs), due to the connection between the elastic connecting piece 1 28 and the elastic connecting piece 2 29 The part has a certain length, which can keep the whole line from being disconnected and play a certain buffering role (at this time, only the first terminal 27 and the second terminal 33 may slide, while the elastic connecting piece 1 28 and the elastic connecting piece 2 29 remain stationary), wherein the first terminal 27 and the second terminal 33 are provided with a buffer spring, when the cable is slightly pulled, the buffer spring ensures that the first terminal 27 and the second terminal 33 remain stationary, and when the external tension is eliminated, the buffer spring pushes the first terminal 27 and the second terminal 33 to return to their original positions, and the first terminal 27 and the second terminal 33 are both provided with an inspection wiring cover 34 to facilitate maintenance. When the electrical components in the first and second electrical connectors 27 and 33 are maintained and replaced, when the first and second electrical connectors 27 and 33 are subjected to a large pulling force, the first and second electrical connectors 27 and 33 move with a large displacement, thereby driving the elastic connecting piece 1 28 and the elastic connecting piece 29 to move. Since the elastic connecting piece 1 28 and the elastic connecting piece 29 both have an elastic effect (a tendency to move in opposite directions), the elastic connecting piece 1 28 and the elastic connecting piece 29 can be quickly disconnected. On the one hand, under the sliding effect of the first and second electrical connectors 27 and 33, the cable can be in a certain degree of relaxation, so that It plays a role in protecting cables. On the other hand, it can quickly disconnect cables and quickly power off the equipment (while saving data) to avoid damage to equipment due to sudden cable breakage. I will not go into details here. In addition, when the distance moved by the power connector 1 27 and the power connector 2 33 is large, the bypass control column 32 will contact the inner wall of the transfer protection box 5 and form a passage with the warning device 6, so that the warning device 6 will sound an alarm. On the one hand, it can remind the staff of dangerous situations. On the other hand, it can remind the staff of the location of the danger, which is convenient for the staff to quickly investigate and repair. I will not go into details here.
