Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic shielding cabinet technology, and in particular to a self-locking component for an electromagnetic shielding cabinet. Background Technology
[0002] Electromagnetic shielding cabinets are used to house electronic communication equipment such as computers, servers, and switches. On the one hand, they prevent electronic equipment from being affected by external electromagnetic interference during operation, and on the other hand, they can isolate electromagnetic waves from harming the human body.
[0003] An electromagnetic shielding cabinet (authorization announcement number: CN207476111U) has been improved in the opening and closing structure of the electromagnetic shielding door. A limiting block is provided on the upper part of the connecting rod and on the opposite side of the sliding block. The cabinet is also equipped with a mechanical lock or combination lock connected to the limiting block to ensure that the electromagnetic shielding door is closed and locked, thereby further increasing the airtightness of the electromagnetic shielding cabinet.
[0004] However, this type of electromagnetic shielding cabinet has some shortcomings in actual use: it requires manual operation by staff to lock, close, and open the electromagnetic shielding door. Since the electromagnetic shielding door is quite heavy, manual operation is inconvenient. Therefore, we propose a self-locking component for the electromagnetic shielding cabinet to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a self-locking component for electromagnetic shielding cabinets, thereby solving the aforementioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A self-locking assembly for an electromagnetic shielding cabinet includes an electromagnetic shielding cabinet body. A rotating rod is rotatably mounted on one outer wall of the electromagnetic shielding cabinet body. An electromagnetic shielding door is fixedly mounted on the rotating rod. First gears are fixedly mounted at both ends of the rotating rod. A first installation chamber and a first circular chamber are formed in the top and bottom of the electromagnetic shielding cabinet body. Each of the two sets of first installation chambers and first circular chambers is provided with an opening drive mechanism for the corresponding first gear. Two side openings are formed on one side of the electromagnetic shielding cabinet body. Locking holes are formed on the inner walls of the two side openings. An inner chamber is formed inside the electromagnetic shielding door. A second gear is rotatably mounted on the inner wall of the inner chamber via a rotating shaft. Multiple side grooves are formed on the inner wall of the inner chamber. The same M-shaped lifting block is movably mounted in two corresponding side grooves. Two hinge plates are hinged between the M-shaped lifting block and the second gear. A locking mechanism for the corresponding locking hole is provided on one side of the M-shaped lifting block. A second installation chamber and a second circular chamber are formed on one inner wall of the inner chamber. A self-locking drive mechanism for the second gear is provided in the second installation chamber and the second circular chamber.
[0008] Preferably, the two sets of first installation chambers and first circular chambers in the top and bottom of the electromagnetic shielding cabinet body are symmetrically arranged, and the first installation chambers and first circular chambers are connected to each other; this facilitates the horizontal movement of the first straight rack in the first installation chamber.
[0009] Preferably, the opening drive mechanism includes a first spur rack and a first electric push rod. The first spur rack is movably installed in the first mounting chamber and meshes with a corresponding first gear. The first electric push rod is fixedly installed on one side of the inner wall of the first circular chamber, and the output end of the first electric push rod is fixedly installed on one side of the first spur rack. Through the two sets of opening drive mechanisms, the electromagnetic shielding door automatically deflects and closes onto the electromagnetic shielding cabinet body.
[0010] Preferably, one end of each of the two hinge plates is hinged to the eccentric part of the second gear, and the two M-shaped lifting blocks are located above and below the second gear, respectively. When the second gear rotates, under the action of the eccentric hinge of the two sets of hinge plates, the two M-shaped lifting blocks are synchronously pushed away from each other.
[0011] Preferably, the locking mechanism includes a bent rod and a locking pin. A bent rod is fixedly installed on one side of the M-shaped lifting block, and one end of the bent rod extends through to the outside of the electromagnetic shielding door and is fixedly installed with a locking pin. The locking pin is adapted to the locking hole. When the locking pin on the bent rod is inserted into the locking hole, the electromagnetic shielding door is automatically locked to the electromagnetic shielding cabinet body.
[0012] Preferably, the second mounting chamber is connected to the second circular chamber, and the second mounting chamber is located on the right inner wall of the inner chamber; this facilitates the lifting and sliding of the second straight rack inside the second mounting chamber.
[0013] Preferably, the self-locking drive mechanism includes a second rack and a second electric push rod. The second rack is movably mounted in the second mounting chamber and meshes with a second gear. The second electric push rod is fixedly mounted on one side of the inner wall of the second circular chamber, and the output end of the second electric push rod is fixedly mounted on one side of the second rack. The self-locking drive mechanism can drive the second gear to rotate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The self-locking component of this electromagnetic shielding cabinet uses two sets of opening drive mechanisms to automatically deflect the electromagnetic shielding door and lock it onto the cabinet body. Then, the self-locking drive mechanism drives the second gear to rotate. Under the action of the eccentric hinge of the two sets of hinge plates, the two M-shaped lifting blocks are pushed away from each other, so that the locking pins on the two bent rods are inserted into the corresponding locking holes. This achieves automatic locking of the electromagnetic shielding door onto the cabinet body, eliminating the need for manual operation of the electromagnetic shielding door on the cabinet body. The operation is simple, fast, and labor-saving. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1-6 A self-locking assembly for an electromagnetic shielding cabinet includes an electromagnetic shielding cabinet body 1. A rotating rod 2 is rotatably mounted on one outer wall of the electromagnetic shielding cabinet body 1. An electromagnetic shielding door 3 is fixedly mounted on the rotating rod 2. First gears 4 are fixedly mounted at both ends of the rotating rod 2. First installation chambers 5 and first circular chambers 6 are provided in the top and bottom of the electromagnetic shielding cabinet body 1. Each of the two sets of first installation chambers 5 and first circular chambers 6 is provided with an opening drive mechanism corresponding to the first gears 4. Two side openings 9 are provided on one side of the electromagnetic shielding cabinet body 1. Locking holes 10 are provided on the inner walls of the two side openings 9. The electromagnetic shielding door... The inner chamber 11 is provided. The inner wall of the inner chamber 11 is rotatably mounted with a second gear 12 via a rotating shaft. The inner wall of the inner chamber 11 is provided with multiple side grooves 13. The same M-shaped lifting block 14 is movably installed in two corresponding side grooves 13. Two hinge plates 15 are hinged between the M-shaped lifting block 14 and the second gear 12. A locking mechanism for a corresponding locking hole 10 is provided on one side of the M-shaped lifting block 14. A second mounting chamber 18 and a second circular chamber 19 are provided on one side of the inner wall of the inner chamber 11. A self-locking drive mechanism for the second gear 12 is provided in the second mounting chamber 18 and the second circular chamber 19.
[0025] Furthermore, the two sets of first mounting chambers 5 and first circular chambers 6 in the top and bottom of the electromagnetic shielding cabinet body 1 are symmetrically arranged, and the first mounting chambers 5 and first circular chambers 6 are connected to each other; this facilitates the horizontal movement of the first straight rack 7 in the first mounting chamber 5.
[0026] Specifically, the opening drive mechanism includes a first straight rack 7 and a first electric push rod 8. The first straight rack 7 is movably installed in the first mounting chamber 5 and meshes with the corresponding first gear 4. The first electric push rod 8 is fixedly installed on one side of the inner wall of the first circular chamber 6, and the output end of the first electric push rod 8 is fixedly installed on one side of the first straight rack 7. Through the two sets of opening drive mechanisms, the electromagnetic shielding door 3 is automatically deflected and then closes onto the electromagnetic shielding cabinet body 1.
[0027] Furthermore, corresponding to the eccentric portion of the two hinge plates 15, one end is hinged to the second gear 12, and the two M-shaped lifting blocks 14 are located above and below the second gear 12, respectively. When the second gear 12 rotates, under the action of the eccentric hinge of the two sets of hinge plates 15, the two M-shaped lifting blocks 14 are pushed away from each other in a synchronous manner.
[0028] Specifically, the locking mechanism includes a bent rod 16 and a locking pin 17. The bent rod 16 is fixedly installed on one side of the M-shaped lifting block 14. One end of the bent rod 16 extends through to the outside of the electromagnetic shielding door 3 and is fixedly installed with the locking pin 17. The locking pin 17 is adapted to the locking hole 10. When the locking pin 17 on the bent rod 16 is inserted into the locking hole 10, the electromagnetic shielding door 3 is automatically locked on the electromagnetic shielding cabinet body 1.
[0029] Furthermore, the second mounting chamber 18 is connected to the second circular chamber 19, and the second mounting chamber 18 is located on the right inner wall of the inner chamber 11; this facilitates the lifting and sliding of the second straight rack 20 inside the second mounting chamber 18.
[0030] Specifically, the self-locking drive mechanism includes a second rack 20 and a second electric push rod 21. The second rack 20 is movably installed in the second mounting chamber 18 and meshes with the second gear 12. The second electric push rod 21 is fixedly installed on one side of the inner wall of the second circular chamber 19, and the output end of the second electric push rod 21 is fixedly installed on one side of the second rack 20. The self-locking drive mechanism can drive the second gear 12 to rotate.
[0031] In use: When it is necessary to close the electromagnetic shielding door 3 of the electromagnetic shielding cabinet body 1, by activating the two first electric push rods 8, the two first straight racks 7 are simultaneously pushed to move outward from the electromagnetic shielding cabinet body 1, thereby driving the two first gears 4 at both ends of the rotating rod 2 to rotate, so that the electromagnetic shielding door 3 automatically deflects and engages on the electromagnetic shielding cabinet body 1. Then, by activating the second electric push rod 21, the second straight rack 20 is pushed upward, thereby driving the second gear 12 to rotate. Under the eccentric hinge action of the two sets of hinge plates 15, the two M-shaped lifting blocks 14 are simultaneously pushed away from each other, thereby driving the two bent rods 16 away from each other, so that the locking pins 17 on the two bent rods 16 are respectively inserted into the corresponding locking holes 10, thereby realizing the automatic locking of the electromagnetic shielding door 3 on the electromagnetic shielding cabinet body 1.
[0032] In summary, the electromagnetic shielding cabinet body 1 in this case uses two sets of opening drive mechanisms to automatically deflect the electromagnetic shielding door 3 and lock it onto the electromagnetic shielding cabinet body 1. Then, through the self-locking drive mechanism, the second gear 12 is driven to rotate. Under the action of the eccentric hinge of the two sets of hinge plates 15, the two M-shaped lifting blocks 14 are pushed away from each other, so that the locking pins 17 on the two bent rods 16 are respectively inserted into the corresponding locking holes 10, thereby automatically locking the electromagnetic shielding door 3 onto the electromagnetic shielding cabinet body 1. This avoids the need for staff to manually operate the locking, closing and opening of the electromagnetic shielding door 3 on the electromagnetic shielding cabinet body 1, making the operation simple, fast and labor-saving.
