Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an integrated sheet metal bracket for power equipment. Background Technology

[0002] In the field of integrated installation of power equipment, integrated sheet metal brackets for power equipment are the core support structure for equipment such as power distribution cabinets, server racks, and network servers. They are mainly used to improve the stability of equipment placement, load-bearing capacity and seismic performance, while facilitating equipment ventilation, wiring and subsequent maintenance. They are widely used in computer rooms, power distribution rooms, industrial control and other scenarios.

[0003] The existing integrated sheet metal bracket for power equipment mainly consists of two parts: the cabinet frame and the base. The base adopts an enclosed load-bearing structure. The cabinet frame and the base, as well as the base and the ground, are all fastened with bolts. The overall fixation is achieved through multiple sets of bolts. It has the advantages of high structural strength, good load-bearing performance, seismic stability, and customizable size. It is the most commonly used connection and installation method between power cabinets and sheet metal bases.

[0004] However, the base is fixed to the ground and the cabinet frame with bolts, and most of the bolts are located in the internal space of the base and the cabinet frame. The internal space is small and the operating field of vision is poor. It is difficult to quickly align the bolt holes during installation, which makes the assembly operation inconvenient and inefficient. At the same time, during subsequent equipment inspection and maintenance, the staff cannot quickly locate the bolt positions and cannot visually check whether the bolts are loose, corroded or fallen off, which increases the difficulty of inspection and maintenance time and is not conducive to the long-term safe and stable operation of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated sheet metal bracket for power equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated sheet metal bracket for power equipment, comprising a cabinet and a base connected by bolts, wherein the outer wall of the bottom of the cabinet and the outer wall of the base are provided with mounting grooves for mounting bolts, and an outer protective frame that slides on the outer wall of the cabinet and is attached to the outer wall of the base, and a pressure frame mechanism that is attached to the top of the bolts is provided in the outer protective frame, and a stop block that slides in the mounting groove is attached to the top of the pressure frame mechanism; a sealing airbag that is attached to the outer wall of the cabinet is provided on the inner wall of the outer protective frame, and an air extraction groove and a movable groove that communicate with the sealing airbag are provided in the outer protective frame; a piston mechanism is provided in the movable groove; an unlocking mechanism for pushing and guiding the stop block is slidably provided in the outer protective frame; and an oil supply groove that communicates with the movable groove and corresponds to the unlocking mechanism is provided in the outer protective frame; hydraulic oil is provided in the oil supply groove and the movable groove above the piston mechanism.

[0012] Preferably, the stop block is installed in the mounting slot opened on the cabinet, and a spring two connected to the stop block is installed on the cabinet. An end roller protruding from its end is installed at the top corner of the outer end of the stop block. During the reset process of the outer protective frame, the end roller will contact the side wall of the top frame to avoid long-term friction between the side wall of the top frame and the stop block.

[0013] The bottom corner of the outer end of the stop block is designed with an angle. After the outer protective frame is moved to the maintenance position, the end roller is in contact with the bottom surface of the pressure block.

[0014] Preferably, the air extraction slots are provided on both inner walls of the outer frame, and the air extraction slots are evenly distributed within the outer frame.

[0019] The electric actuator is installed in the hand grip groove and fixedly connected to the bottom surface of the lifting plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, through the combination of an open mounting slot on the outside and an outer protective frame, completely solves the problems of traditional power equipment bracket bolts being hidden on the inside, difficult assembly and alignment, inconvenient inspection and observation, and limited maintenance space. All bolts are visible and operable on the outside, making installation and alignment more precise, inspection more intuitive, and disassembly more convenient, greatly improving the assembly and maintenance efficiency of the power cabinet and base. At the same time, the outer protective frame supports and restricts the outer wall of the cabinet and base, further improving the lateral stability of the outer wall of the cabinet and base, while reducing the lateral pressure on the bolts.

[0022] 2. This invention uses a pressure frame mechanism and a stop block linkage locking structure to continuously press the top of the bolt with the pressure block, and with the stop block mechanically limiting the top frame, it can achieve all-round anti-loosening and anti-detachment of the bolt. Even under long-term vibration conditions of the equipment, it can maintain a tight state, effectively avoid the safety hazards caused by bolt loosening and falling off, and improve the operational stability and safety of power equipment.

[0023] 3. This invention uses a sealing airbag and piston mechanism to work together. Under normal conditions, the airbag expands and seals to prevent a large amount of dust, water vapor and corrosive gas from entering the mounting groove, thus delaying the rusting and aging of the bolts. During maintenance, the airbag automatically deflates and contracts to make way for the movement of the outer protective frame, taking into account both long-term protection performance and convenient maintenance needs, and significantly extending the service life of the bracket and connecting bolts.

[0024] 4. This invention uses an unlocking mechanism and a stop block automatic guide and avoidance structure. During the lifting and lowering of the outer protective frame, it relies on the cooperation of the angle and the end roller to achieve automatic avoidance and automatic limit. No manual adjustment or assistance is required. The movement is smooth and without jamming. It automatically locks when in place. It can quickly expose the installation slot for maintenance and can stably reset to achieve protection. It is reliable in operation and has a low failure rate. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-9 The present invention provides the following technical solution: an integrated sheet metal bracket for power equipment, comprising a cabinet 1 and a base 2 connected by bolts 4. The outer bottom wall of the cabinet 1 and the outer wall of the base 2 are both provided with mounting grooves 3 for mounting the bolts 4. An outer protective frame 5, which is attached to the outer wall of the base 2, is slidably mounted on the outer wall of the cabinet 1. A pressure frame mechanism 6, which is attached to the top of the bolts 4, is provided inside the outer protective frame 5. A stop block 7, which is slidably mounted in the mounting groove 3, is attached to the top of the pressure frame mechanism 6. A sealing airbag 8, which is attached to the outer wall of the cabinet 1, is provided inside the outer protective frame 5. An air extraction groove 9 and a movable groove 1, which communicate with the sealing airbag 8, are also provided inside the outer protective frame 5. 0. The movable groove 10 is equipped with a piston mechanism 11. The outer protective frame 5 is equipped with an unlocking mechanism 12 for pushing and guiding the stop 7. The outer protective frame 5 is also equipped with an oil supply groove 13 that communicates with the movable groove 10 and corresponds to the unlocking mechanism 12. Hydraulic oil is provided in the oil supply groove 13 and the movable groove 10 above the piston mechanism 11. The outer wall of the outer protective frame 5 is equipped with a hand grip groove 14. The top of the hand grip groove 14 is equipped with a driver 15 for driving the piston mechanism 11 and connected to the pressure frame mechanism 6. When the driver 15 is activated, the sealing airbag 8 will contract, the pressure frame mechanism 6 will separate from the bolt 4 and the stop 7, and the unlocking mechanism 12 will operate.

[0037] In one embodiment of the present invention, multiple sets of mounting slots 3 are symmetrically opened on the bottom side wall of the cabinet 1 and the outer wall of the base 2, and multiple bolts 4 are provided in each mounting slot 3. The mounting slot 3 is designed with an opening to facilitate subsequent observation. The width of the opening of the mounting slot 3 is greater than the length of the bolts 4. The inner wall of the outer protective frame 5 is attached to the outer wall of the cabinet 1 and the base 2, and the bottom of the outer protective frame 5 is on the same plane as the bottom surface of the base 2. The outer protective frame 5 wraps around the outer wall of the cabinet 1 and the base 2 to cover the opening of the mounting slot 3.

[0038] The mounting slot 3 adopts an externally open structure, which facilitates the alignment, tightening, and status observation of the bolts 4. It can also achieve full protection through the outer protective frame 5, preventing a large amount of dust and moisture from entering. At the same time, the outer protective frame 5 supports and restricts the outer walls of the cabinet 1 and the base 2, further improving the lateral stability of the outer walls of the cabinet 1 and the base 2, while reducing the lateral pressure on the bolts 4, thus balancing assembly convenience and operational safety.

[0039] In one embodiment of the present invention, the pressure frame mechanism 6 includes a movable frame 61 slidably installed inside the outer protective frame 5, and two pressure blocks 62 located in the mounting groove 3 are installed at the ends of the movable frame 61. The bottom surface of the pressure block 62 is in contact with the top surface of the bolt 4, and a top frame 63 in contact with the bottom surface of the stop block 7 is installed on the top of the upper pressure block 62. Multiple springs 64 in contact with the inner wall of the movable frame 61 are installed inside the outer protective frame 5. Each pressure block 62 is equipped with a resistance-reducing wheel 65 protruding from the side wall of the pressure block 62. The springs 64 always push the movable frame 61 outward, so that the pressure block 62 stably presses the head of the bolt 4, realizing anti-loosening limit. The resistance-reducing wheel 65 can reduce the frictional resistance when the outer protective frame 5 slides, ensuring smooth movement.

[0040] In one embodiment of the present invention, the stop block 7 is installed in the mounting slot 3 on the cabinet 1, and the cabinet 1 is equipped with a spring 71 connected to the stop block 7. An end roller 72 protruding from the top corner of the outer end of the stop block 7 is installed. During the resetting process of the outer protective frame 5, the end roller 72 will contact the side wall of the top frame 63 to avoid long-term friction between the side wall of the top frame 63 and the stop block 7. The bottom corner of the outer end of the stop block 7 is designed with an angle. After the outer protective frame 5 moves to the maintenance position, the end roller 72 is in contact with the bottom surface of the pressure block 62. The stop block 7 automatically extends under the action of the spring 71 and cooperates with the top frame 63 to form a mechanical lock to prevent the outer protective frame 5 from being accidentally displaced. The end roller 72 and the angled design can realize automatic guidance and avoidance, and the lifting and positioning can be completed without manual intervention.

[0041] In one embodiment of the present invention, air extraction slots 9 are provided on both inner walls of the outer frame 5, and the air extraction slots 9 are evenly distributed within the outer frame 5. Multiple air extraction slots 9 on one side of the outer frame 5 are connected to the sealing airbag 8 and the movable slot 10. The outer wall of the cabinet 1 is provided with a sealing slot 81 that cooperates with the sealing airbag 8. The piston mechanism 11 includes a lifting piston 111 slidably installed within the movable slot 10, and multiple limiting rods 112 slidably connected to the outer frame 5 are installed on the top of the lifting piston 111. The outer wall of the limiting rods 112... Each is fitted with a spring 113 that is in contact with the top surface of the lifting piston 111 and the movable groove 10. The lifting piston 111 divides the movable groove 10 into two chambers. The top chamber of the lifting piston 111 is used to store hydraulic oil, and the bottom chamber is used to extract gas from the sealing airbag 8 through the air extraction groove 9 when the lifting piston 111 moves upward. When the lifting piston 111 moves upward, the air extraction and hydraulic oil pushing are completed simultaneously, so that the sealing airbag 8 contracts and disengages from the sealing groove 81, making way for the movement of the outer protective frame 5, and realizing the linkage between sealing release and mechanism unlocking.

[0042] In one embodiment of the present invention, the unlocking mechanism 12 includes an unlocking block 121 that is slidably installed inside the outer protective frame 5 and slidably connected to the bottom surface of the pressure block 62. The inner end of the unlocking block 121 is connected to a transverse piston 122 that is slidably installed inside the outer protective frame 5. The inner end of the transverse piston 122 is in contact with the hydraulic oil in the oil supply tank 13. A spring 123 connected to the outer end of the transverse piston 122 is installed inside the outer protective frame 5. The bottom corner of the outer end of the unlocking block 121 is designed with an angle.

[0043] During the descent of the outer protective frame 5, the outer corner of the unlocking block 121 will contact the end roller 72; the hydraulic oil pushes the transverse piston 122 to drive the unlocking block 121 to extend, and the angled surface cooperates with the end roller 72 to realize the automatic retraction of the stop block 7 to avoid obstruction, ensuring that the outer protective frame 5 rises and falls without jamming.

[0044] In one embodiment of the present invention, the driver 15 is composed of a lifting plate 151 and a lifting rod 152, or a lifting plate 151, a lifting rod 152 and an electric push rod. The lifting plate 151 is slidably installed in the grip groove 14, and the top of the lifting plate 151 is equipped with a lifting rod 152 connected to the bottom surface of the lifting piston 111. The bottom of the lifting plate 151 is equipped with a pull rope 16 connected to the movable frame 61. The electric push rod is installed in the grip groove 14 and is fixedly connected to the bottom surface of the lifting plate 151.

[0045] The actuator 15 adopts a dual-mode drive of manual or electric, and can simultaneously complete the sealing shrinkage, pressing frame unlocking and hydraulic transmission in one action. It is simple to operate and reliable in linkage.

[0046] Working principle: When this integrated sheet metal bracket for power equipment is in operation, the outer protective frame 5 continuously wraps around the cabinet 1 and the base 2, while the sealing airbag 8 forms a ring seal, preventing a large amount of dust and moisture from entering the mounting groove 3, effectively reducing the probability of bolt 4 rusting and loosening; at the same time, the pressure block 62 always presses the head of the bolt 4, and together with the stop block 7 to limit the top frame 63, the bolt 4 cannot rotate and fall off under the vibration environment of equipment operation, achieving long-term anti-loosening protection; the mounting groove 3 adopts an open design, which, together with the shielding of the outer protective frame 5, facilitates the installation of bolt 4 and facilitates subsequent observation of the bolt status;

[0047] When bolt 4 needs to be inspected or disassembled, start the driver 15 (by manually raising the lifting plate 151 or by starting the electric push rod to drive the lifting plate 151), so that the lifting plate 151 moves upward, thereby causing the lifting plate 151 to drive the lifting rod 152 to move upward, pushing the lifting piston 111 to move upward along the movable groove 10. During this process, the lifting piston 111 will compress the spring 113. When the lifting piston 111 moves upward, it extracts part of the gas in the sealing airbag 8 through the air extraction groove 9, causing the sealing airbag 8 to contract and separate from the sealing groove 81, releasing the outer wall seal and making way for the outer protective frame 5 to move.

[0048] As the lifting plate 151 moves upward, it will drive the pull rope 16 to pull the movable frame 61 into the outer guard frame 5, and overcome the elastic force of the spring 64 to retract inward, causing the pressure block 62 to separate from the bolt 4. At the same time, the top frame 63 will also separate from the stop block 7, releasing the locking restriction on the bolt 4, so that the bolt 4 can be freely turned and disassembled.

[0049] Furthermore, during the upward movement of the lifting piston 111, the hydraulic oil in the upper chamber is squeezed. The hydraulic oil flows through the oil delivery groove 13 to the transverse piston 122 and pushes the transverse piston 122 to move outward, causing the unlocking block 121 to extend outward, providing guidance and avoidance for the subsequent movement of the outer protective frame 5.

[0050] After the drive 15 is started and unlocked, the pressure block 62 and the top bracket 63 are moved to the outside of the cabinet 1 and the base 2. At the same time, the stop block 7 is in the state of extending out of the mounting slot 3 and located outside the cabinet 1. The outer end of the unlocking block 121 and the outer end of the pressure block 62 are on the same vertical plane. Then, the user can hold the handle slot 14 and pull the outer protective frame 5 upward, so that it slides upward along the outer wall of the cabinet 1 and the base 2. During the sliding process, the drag reducing wheel 65 will contact the bottom of the outer end of the stop block 7 at an angle, pushing the stop block 7 into the mounting slot 3, so that the stop block 7 avoids the pressure block 62, ensuring that the pressure block 62 can move smoothly with the outer protective frame 5 to the maintenance position.

[0051] When the outer protective frame 5 moves to the maintenance position, the pressure block 62 and the stop block 7 are misaligned. Then the reset driver 15 is reset, which releases the thrust on the transverse piston 122. At the same time, the lifting piston 111 will be reset under the action of the third spring 113, which will cause the hydraulic oil to flow back. The transverse piston 122 will be reset under the action of the fourth spring 123 and the retracted hydraulic oil. At this time, the stop block 7 will move outward under the action of the second spring 71, and the top of the end roller 72 will contact the bottom surface of the pressure block 62 to receive the pressure block 62. At this time, the position of the outer protective frame 5 is restricted.

[0052] At this point, the mounting slot 3 is fully exposed, allowing for easy observation and maintenance of the bolt 4.

[0053] After the maintenance is completed, the driver 15 is restarted to move the unlocking block 121 outward. At this time, the end of the unlocking block 121 will push the end roller 72, causing the stop block 7 to slide into the mounting groove 3, thereby separating the end roller 72 from the pressure block 62. At this time, the outer protective frame 5 can be reset downward. As the stop block 7 separates from the first set of pressure blocks 62 and the drag reducing wheel 65, the restriction will be contacted again, and the end of the stop block 7 will extend again. As the outer protective frame 5 continues to descend, the end roller 72 at the top of the stop block 7 will make oblique contact with the end of the unlocking block 121 at the bottom of the second set of pressure blocks 62, causing the end roller 72 to move back into the mounting groove 3 under the oblique guidance of the unlocking block 121, ensuring that the outer protective frame 5 can be reset smoothly.

[0054] After the outer frame 5 is reset, the driver 15 is reset again, so that the pressure block 62 and other components are reset. At this time, the top of the top frame 63 will cooperate with the bottom of the stop block 7 to restrict the position of the outer frame 5, while the pressure block 62 will restrict the top of the bolt 4. Since the outer frame 5 cannot move upward, this ensures that the bolt 4 will not loosen.

[0055] When assembling and fixing the cabinet 1 and the base 2, first lift the outer protective frame 5 upward along the outer wall of the cabinet 1, so that the outer protective frame 5 is moved to the maintenance station as a whole.

[0056] Then, the base 2 is placed stably on the preset mounting base position, and the base 2 is fastened to the mounting base with bolts 4. The top of the bolts 4 is completely inside the mounting groove 3. All installation operations are completed on the outside of the equipment, without having to reach into the narrow space inside the cabinet 1 and the base 2, which greatly improves the ease of installation and alignment accuracy.

[0057] After the base 2 is fixed, the cabinet 1 is smoothly hoisted or moved to the top of the base 2, so that the bottom of the cabinet 1 is precisely aligned with the top of the base 2; the cabinet 1 and the base 2 are then fastened together as one unit with bolts 4, and the top of the bolts 4 are also completely located in the mounting groove 3; through the open mounting groove 3 on the outside, the installation status, tightness and alignment of the bolts 4 can be directly observed, so as to achieve quick, stable and reliable assembly of the cabinet 1 and the base 2;

[0058] After the cabinet 1 and base 2 are assembled, the limit of the outer protective frame 5 is released, and the outer protective frame 5 is smoothly reset downward along the outer wall of the cabinet 1 and base 2 to the restricted state, thus completing the entire process of assembly, locking and protection.
