Description

Technical Field

[0001] This application relates to the technical field of electrical cabinets, and in particular to a portable electrical cabinet. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials to protect components to work properly. The manufacturing materials of electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Among them, the cold-rolled steel plate is softer and more suitable for the manufacture of electrical cabinets. Electrical cabinets are widely used mainly in industries such as environmental protection, power systems, and fire safety monitoring, and play an important role in protecting components.

[0003] Regarding the above related technologies, since existing electrical cabinets are generally made of steel plates, their own weight is relatively large. Therefore, when it is necessary to carry an electrical cabinet over a short distance, relevant personnel often need to first carry the electrical cabinet onto an additional transportation device to achieve the handling of the electrical cabinet, which greatly increases the workload of relevant personnel and thus reduces the handling efficiency of the electrical cabinet. Summary of the Invention

[0004] In order to facilitate relevant personnel to carry an electrical cabinet, this application provides a portable electrical cabinet.

[0005] A portable electrical cabinet provided by this application adopts the following technical solutions:

[0006] A portable electrical cabinet includes a cabinet body. An installation seat is further provided below the cabinet body. The bottom of the cabinet body is embedded in the installation seat and installed on the installation seat. A plurality of rollers are further provided at the bottom of the installation seat, and each roller is rotatably connected to the installation seat.

[0007] By adopting the above technical solutions, compared with the prior art, when it is necessary to carry an electrical cabinet over a short distance, relevant personnel need to first carry the electrical cabinet onto an additional transportation device to achieve the handling of the electrical cabinet, which greatly increases the workload of relevant personnel; through the setting of the installation seat and rollers in this application, the cabinet body part of the electrical cabinet can be installed on the installation seat, so that when relevant personnel need to carry the electrical cabinet over a short distance, they only need to push the installation seat to make the rollers at the bottom of the installation seat rotate, so that the installation seat can drive the cabinet body to move, thereby achieving the handling of the cabinet body, and thus there is no need for relevant personnel to manually carry the cabinet body onto an additional transportation device, effectively facilitating the handling of relevant personnel, further improving the handling efficiency of the electrical cabinet in this application, and at the same time reducing the probability of internal components being damaged due to bumps during the handling of the electrical cabinet.

[0008] Preferably, an installation mechanism is further provided on the mounting base. The installation mechanism includes an installation frame, a fixing frame, and a fixing component. The installation frame is located on one side of the cabinet body, and the bottom is rotatably connected to the cabinet body. The top of the installation frame extends upward and abuts against the side wall of the cabinet body. The fixing frame is arranged on the top of the installation frame and inserted into the cabinet body. The fixing component is used to lock the fixing frame and the cabinet body together.

[0009] By adopting the above technical solution, the setting of the installation mechanism enables, after the bottom of the cabinet body is embedded in the top of the mounting base, the relevant personnel to rotate the installation frame, so that the fixing frame on the installation frame is inserted into the cabinet body, and the fixing component is used to lock between the fixing frame and the cabinet body, realizing the installation of the cabinet body on the mounting base, effectively facilitating the relevant personnel to install the cabinet body on the mounting base. At the same time, the locking between the fixing frame and the cabinet body can be released through the fixing component, effectively facilitating the replacement and disassembly of the cabinet body by the relevant personnel.

[0010] Preferably, an installation opening for the fixing frame to pass through is provided on the side wall of the cabinet body. A closing mechanism is further provided in the cabinet body. The closing mechanism includes a closing frame and a closing component. The top end of the closing frame is rotatably connected to the cabinet body. The closing frame is used to close the installation opening. The closing component is used to drive the closing frame to rotate.

[0011] By adopting the above technical solution, the setting of the closing mechanism enables, after the cabinet body is disassembled from the mounting base, the closing component to drive the closing frame to rotate, so that the closing frame closes the installation opening, thereby reducing the probability of external objects entering the inside of the closing frame through the installation opening, effectively ensuring the cleanliness inside the cabinet body; at the same time, the closing component can also drive the closing frame to open the installation opening, so that the fixing frame can be smoothly inserted into the installation opening.

[0012] Preferably, the installation mechanism further includes a docking component. The docking component includes a docking frame and a linkage member. The docking frame is slidably connected to the cabinet body, and the sliding direction is perpendicular to the insertion direction of the fixing frame. The fixing frame is inserted into the docking frame. The fixing component is used to lock the fixing frame and the docking frame together. The closing frame drives the docking frame to slide through the linkage member and makes the docking frame slide to the displacement path of the fixing frame.

[0013] By adopting the above technical solution, the setting of the docking component enables, when the closing frame opens the installation opening, the docking frame to be driven to slide through the linkage member, so that the docking frame gradually slides to the displacement path of the fixing frame, enabling the fixing frame to be inserted into the docking frame; at the same time, the existence of the docking component also enables, when the closing frame gradually closes, the docking frame to be driven to slide through the linkage member, so that the docking frame completely slides into the cabinet body, reducing the probability of the docking frame being blocked by foreign objects.

[0014] Preferably, a locking component is further provided on the fixing frame. The locking component includes a locking frame and an elastic member. One end of the locking frame is located inside the fixing frame and is slidably connected to the fixing frame. The other end of the locking frame extends outside the fixing frame and is inserted into the docking frame. A locking groove for inserting the locking frame is further formed in the docking frame. The elastic member is used to continuously insert the locking frame into the locking groove through its own elastic force.

[0015] By adopting the above technical solution, the setting of the locking component enables the elastic member to drive the locking frame to be continuously inserted into the corresponding locking groove through its own elastic force when the fixing frame is inserted into the locking frame, thereby preventing the fixing frame from detaching from the docking frame, realizing the locking between the fixing frame and the docking frame, and further realizing the locking between the fixing frame and the cabinet body, effectively facilitating the locking of the cabinet body by relevant personnel.

[0016] Preferably, the fixing frame is rotatably connected to the mounting frame, and the rotation direction is the insertion direction of the fixing frame. An unlocking groove is further formed in the docking frame. The unlocking groove is communicated with the locking groove, and the side wall of one end of the locking groove far from the unlocking groove gradually extends towards the side wall of the fixing frame. The fixing component is used to limit the rotation of the fixing frame.

[0017] By adopting the above technical solution, the setting of the unlocking groove enables relevant personnel to drive the fixing frame to rotate through the fixing component when it is necessary to disassemble the cabinet body and thus the locking frame needs to be unlocked. As a result, the fixing frame drives the locking frame to rotate, so that the end of the locking frame contacts the inner wall of the unlocking groove. Furthermore, under the action of the abutment, the locking frame gradually slides into the fixing frame, and finally the locking frame completely disengages from the unlocking groove, enabling the fixing frame to detach from the docking frame, effectively facilitating the operation of relevant personnel. At the same time, the fixing component can also limit the rotation of the fixing frame, thereby realizing the locking of the fixing frame.

[0018] Preferably, the linkage member includes a linkage frame. One end of the linkage frame is rotatably connected to the closing frame, and the other end of the linkage frame is rotatably connected to the docking frame.

[0019] By adopting the above technical solution, the setting of the linkage frame enables the closing frame to drive the linkage frame to displace when the closing frame rotates, so that the closing frame drives the docking frame to rotate through the linkage frame, realizing the linkage between the closing frame and the docking frame, effectively facilitating the operation of relevant personnel, and at the same time saving the active device for driving the docking frame to rotate.

[0020] Preferably, a plurality of positioning rods are further provided on the top of the mounting base. The top of the positioning rod extends upward and is inserted into the bottom of the cabinet body. A plurality of positioning grooves for inserting the positioning rods are further formed on the bottom of the cabinet body.

[0021] By adopting the above technical solution, the arrangement of the positioning rods enables relevant personnel to position the installation position of the cabinet body by inserting the positioning rods into the corresponding positioning grooves when gradually embedding the cabinet body on the mounting base, effectively reducing the probability of the cabinet body being installed offset, thus facilitating the installation of the cabinet body by relevant personnel and improving the installation efficiency of the cabinet body.

[0022] Preferably, the closing assembly includes a moving frame and a driving frame. The moving frame is located inside the cabinet body and is slidably connected to the cabinet body, and the sliding direction is the height direction of the cabinet body. One of the positioning rods is located on the displacement path when the moving frame moves downward together with the cabinet body. One end of the driving frame is rotatably connected to the moving frame, and the other end is rotatably connected to the closing frame.

[0023] By adopting the above technical solution, the arrangement of the closing assembly enables the positioning frame to abut against the moving frame when gradually inserted into the positioning groove during the process of gradually installing the cabinet body on the mounting base, thereby driving the moving frame to slide upward, and then enabling the moving frame to drive the corresponding driving frame to displace, and further enabling the driving frame to drive the closing frame to rotate, realizing the driving of the closing frame, thus eliminating the need for relevant personnel to manually rotate the closing frame and effectively facilitating the operation of relevant personnel.

[0024] Preferably, the closing assembly further includes a reset member, and the reset member is used to supply the moving frame to return downward to the initial position through its own elastic force.

[0025] By adopting the above technical solution, the arrangement of the reset member enables the reset member to drive the moving frame to slide downward through its own elastic force after the cabinet body is separated from the mounting base, so that the moving frame returns to the initial position, and then the closing frame rotates to close the installation opening, effectively facilitating the operation of relevant personnel.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The installation base and rollers are arranged such that the cabinet body part of the electrical cabinet can be installed on the installation base. When relevant personnel need to carry the electrical cabinet over a short distance, they only need to push the installation base, causing the rollers at the bottom of the installation base to rotate, so that the installation base can drive the cabinet body to move, thereby realizing the handling of the cabinet body. Thus, it is not necessary for relevant personnel to manually carry the cabinet body onto an additional transportation device, effectively facilitating the handling of relevant personnel, improving the handling efficiency of the electrical cabinet of the present application, and at the same time reducing the probability of damage to internal components due to jolts during the handling of the electrical cabinet;

[0028] 2. The installation mechanism is arranged such that after the bottom of the cabinet body is embedded in the top of the installation base, relevant personnel can rotate the installation frame, insert the fixing frame on the installation frame into the cabinet body, and lock between the fixing frame and the cabinet body through the fixing component, realizing the installation of the cabinet body on the installation base. It effectively facilitates relevant personnel to install the cabinet body on the installation base. At the same time, the locking between the fixing frame and the cabinet body can be released through the fixing component, effectively facilitating relevant personnel to replace and disassemble the cabinet body;

[0029] 3. The locking component is arranged such that when the fixing frame is inserted into the locking frame, the elastic member can drive the locking frame to continuously insert into the corresponding locking groove through its own elastic force, thereby preventing the fixing frame from detaching from the docking frame, realizing the locking between the fixing frame and the docking frame, and further realizing the locking between the fixing frame and the cabinet body, effectively facilitating relevant personnel to lock the cabinet body.

Each positioning rod 21 is inserted into the corresponding positioning groove 11 to position the cabinet body 1.

[0039] Referring to Figure 2 , in the embodiment of the present application, an additional box body can be further arranged in the cabinet body 1. The box body is fixedly connected to the cabinet body 1 and is used for installing electronic components to protect the electronic components and form a chamber between the cabinet body 1 and the box body. Installation openings 12 are formed on the outer side walls of both sides of the cabinet body 1 along its length direction. A closing mechanism 4 is further arranged in the cabinet body 1. In the embodiment of the present application, the closing mechanism 4 is located in the space between the cabinet body 1 and the above box body.

[0040] Referring to Figure 2, the closing mechanism 4 includes a closing frame 41 and a closing component 42. In the embodiment of the present application, the number of the closing frames 41 is set to two, and the two closing frames 41 correspond to the two mounting openings 12. The top of each closing frame 41 is rotatably connected to the inner wall of the cabinet body 1 through a support and a pin shaft, and is located above the corresponding mounting opening 12. The cross-sectional area of each closing frame 41 is larger than the opening area of the mounting opening 12 to close the mounting opening 12.

[0041] Refer to Figure 2 , the closing component 42 includes a moving frame 421, a resetting member 422 and a driving frame 423. In the embodiment of the present application, the number of the driving frames 423 is set to two, and the two driving frames 423 correspond to the two closing frames 41. The moving frame 421 is located at the bottom inside the cabinet body 1, and two sliding portions 4211 extend upward from the top of the moving frame 421. Each sliding portion 4211 is integrally formed with the moving frame 421. The top end of each sliding portion 4211 extends into the inner wall of the cabinet body 1 and is slidably connected to the cabinet body 1, and the sliding direction is the height direction of the cabinet body 1.

[0042] Refer to Figure 2 , in the embodiment of the present application, the number of the resetting members 422 is set to two, and the two resetting members 422 are arranged in one-to-one correspondence with the two sliding portions 4211, and each resetting member 422 is set as a compression spring. Each such compression spring is sleeved on the corresponding sliding portion 4211, and the bottom end abuts against the top wall of the main body portion of the moving frame 421, and the top end abuts against the inner wall of the cabinet body 1 so as to compress itself when the moving frame 421 moves upward relative to the cabinet body 1.

[0043] Refer to Figure 2 , each positioning rod 21 is located on the displacement path when the moving frame 421 moves downward together with the cabinet body 1, so that the top end of each positioning rod 21 can push the moving frame 421 to move upward relative to the cabinet body 1. The two ends of each moving frame 421 along its own length direction extend to the ends of the cabinet body 1, and the two driving frames 423 are respectively arranged at the two ends of the moving frame 421.

[0044] Refer to Figure 2 and Figure 3 , one end of each driving frame 423 is rotatably connected to the corresponding end of the moving frame 421 through a pin shaft, and the other end of each driving frame 423 extends upward and is rotatably connected to the bottom of the corresponding closing frame 41 through a pin shaft to realize the transmission of the closing frame 41.

[0045] Refer to Figure 1 and Figure 2, in the initial state, that is, when the bottom of the cabinet body 1 is not embedded in the mounting base 2, the moving frame 421 is located at the top of its sliding path. At this time, each closing frame 41 is in contact with the inner side wall of the cabinet body 1 to close the corresponding mounting opening 12. When the cabinet body 1 is gradually embedded in the mounting base 2 so that the positioning rod 21 is inserted into the positioning groove 11, the positioning rod 21 gradually approaches the moving frame 421.

[0046] Refer to Figure 1 and Figure 2 , when the positioning rod 21 abuts against the moving frame 421, the positioning rod 21 pushes the moving frame 421 to slide upward relative to the cabinet body 1. At this time, the moving frame 421 drives the driving frame 423 to displace, so that the top end of the driving frame 423 moves upward, driving the corresponding closing frame 41 to rotate, and further causing the closing frame 41 to gradually open the mounting opening 12. When the bottom of the cabinet body 1 abuts against the top of the mounting base 2, the positioning rod 21 reaches the deepest part inside the cabinet body 1. At this time, the closing frame 41 completely opens the mounting opening 12.

[0047] Refer to Figure 1 , Figure 2 and Figure 3 , an installation mechanism 5 is further provided on the mounting base 2. In the embodiment of the present application, the number of the installation mechanisms 5 is set to two, and the two installation mechanisms 5 are arranged in one-to-one correspondence with the two mounting openings 12. Each installation mechanism 5 includes a docking component 51, a mounting frame 52, a fixing frame 53, and a fixing component 54. The docking components 51 are arranged in one-to-one correspondence with the closing frames 41. Each docking component 51 includes a docking frame 511 and a linkage member 512, and each linkage member 512 includes a linkage frame 5121.

[0048] Refer to Figure 2 and Figure 3 , each docking frame 511 is slidably connected to the inner wall of the cabinet body 1, and is located below the corresponding mounting opening 12, and the length of each docking frame 511 is greater than the length of the corresponding mounting opening 12. Each docking frame 511 is slidably connected to the cabinet body 1 through a slide rail, and the sliding direction is the height direction of the cabinet body 1. One end of each linkage frame 5121 is rotatably connected to the corresponding docking frame 511 through a pin shaft, and the other end of each linkage frame 5121 is rotatably connected to the corresponding closing frame 41 through a pin shaft.

[0049] Refer to Figure 2 and Figure 3, in the initial state, that is, when the docking frame 511 is in the closed state, the docking frame 511 is located below the corresponding closed frame 41, that is, below the corresponding installation opening 12. When the closed frame 41 rotates under the drive of the driving frame 423 to gradually open the installation opening 12, the closed frame 41 drives the corresponding docking frame 511 to move upward through the linkage frame 5121, so that the middle part of the docking frame 511 gradually moves to a position corresponding to the installation opening 12, so that the docking frame 511 is exposed outside the cabinet body 1.

[0050] Referring to Figure 2 and Figure 4 , the two mounting frames 52 are respectively located at both ends of the cabinet body 1 along its length direction, and the bottom ends are respectively rotationally connected to the top of the mounting seat 2 through a pin shaft, and the rotation axes are all in the width direction of the cabinet body 1. Each mounting frame 52 is attached to the corresponding side wall of the cabinet body 1. In the embodiment of the present application, the fixing components 54 are all set as cabinet locks, and each cabinet lock is installed on the top of the corresponding mounting frame 52 and is equipped with a key for relevant personnel to open.

[0051] Referring to Figure 2 and Figure 4 , each fixing frame 53 is rotationally connected to the corresponding mounting frame 52 through a bearing, and one end is fixedly connected to the corresponding cabinet lock described above, so that the cabinet lock can drive the fixing frame 53 to rotate. One end of each fixing frame 53 away from the mounting frame 52 passes through the corresponding installation opening 12 and is finally inserted into the corresponding docking frame 511.

[0052] Referring to Figure 4 , insertion slots 5111 are formed on the side walls of each docking frame 511 exposed outside the cabinet body 1 for the corresponding fixing frames 53 to be inserted, and the cross-sectional size of the insertion slots 5111 is larger than the cross-sectional size of the fixing frames 53, so that the fixing frames 53 can be smoothly inserted into the insertion slots 5111.

[0053] Referring to Figure 4 and Figure 5 , a locking component 6 is arranged on each fixing frame 53, and each locking component 6 includes a locking frame 61 and an elastic member 62. One end of each locking frame 61 is located inside the corresponding fixing frame 53 and is slidably connected to the inner wall of the corresponding fixing frame 53. The other end of each locking frame 61 extends out of the fixing frame 53 and is inserted into the docking frame 511. Locking slots 5112 for the locking frames 61 to be inserted are formed in each docking frame 511. Each locking slot 5112 is adapted to the locking frame 61 and is communicated with the corresponding insertion slot 5111.

[0054] Referring to Figure 4 and Figure 5, in the embodiments of the present application, the elastic members 62 are all arranged as compression springs. The compression springs are located inside the corresponding fixing brackets 53 and are all on one side of the corresponding locking brackets 61 along their sliding directions. One end of each compression spring abuts against the corresponding locking bracket 61, and the other end abuts against the inner wall of the corresponding fixing bracket 53, so as to supply the corresponding locking bracket 61 to be continuously inserted into the corresponding locking groove 5112 through its own elastic force.

[0055] Referring to Figure 4 and Figure 5 , on one side end of each locking bracket 61 away from the fixing component 54, a guiding surface is provided, so that when the locking bracket 61 approaches the docking bracket 511 along with the fixing bracket 53, the guiding surface can abut against the docking bracket 511, so that the locking bracket 61 retracts into the fixing bracket 53, and the locking bracket 61 and the fixing bracket 53 can smoothly enter the corresponding docking bracket 511.

[0056] Referring to Figure 4 and Figure 5 , an unlocking groove 5113 is provided in each docking bracket 511. One end of each unlocking groove 5113 is communicated with the locking groove 5112, and the other end of each unlocking groove 5113 is communicated with one end of the corresponding inserting groove 5111 away from the unlocking groove 5113, and the inner side wall of this end gradually extends towards the side wall of the corresponding fixing bracket 53, so that when the locking bracket 61 rotates, it can slide relative to the fixing bracket 53 by abutting against the inner wall of the unlocking groove 5113, so that the locking bracket 61 gradually retracts into the fixing bracket 53 to realize unlocking.

[0057] The implementation principle of a portable electrical cabinet in the embodiments of the present application is as follows: when the cabinet body 1 needs to be installed on the mounting seat 2, first embed the bottom of the cabinet body 1 into the top groove of the mounting seat 2, and make the positioning rod 21 gradually inserted into the positioning groove 11 at the bottom of the cabinet body 1. During this process, the positioning rod 21 gradually abuts against the moving bracket 421, so that the moving bracket 421 slides, and further makes the moving bracket 421 drive the closing bracket 41 to rotate through the driving bracket 423, so as to gradually open the installation opening 12. During this process, the closing bracket 41 drives the corresponding docking bracket 511 to slide upward through the linkage bracket 5121, so that the surface of the docking bracket 511 with the inserting groove 5111 gradually exposes outside the cabinet body 1.

[0058] After that, rotate the mounting bracket 52, so that the fixing bracket 53 on the mounting bracket 52 passes through the corresponding installation opening 12, and make the end of the fixing bracket 53 gradually inserted into the inserting groove 5111 on the corresponding docking bracket 511, and when the fixing bracket 53 reaches the bottom of the inserting groove 5111, one end of the locking bracket 61 can be driven by the elastic member 62 to move out of the fixing bracket 53, so as to lock between the mounting bracket 52 and the docking bracket 511.

[0059] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
