Description

Technical Field

[0001] This utility model relates to the field of elevator control cabinet technology, and in particular to an elevator control cabinet door opening device. Background Technology

[0002] Elevator control cabinets are high-strength explosion-proof products, commonly used for explosion protection in high-voltage electrical systems. Their enclosures can withstand the internal explosion of flammable mixtures that penetrate through any joint or structural gap into the enclosure without damage, and will not ignite an external explosive atmosphere formed by one or more gases or vapors. The main ignition source is sparks, and elevator control cabinets mainly isolate sparks and take explosion-proof measures, while also having explosion-resistant strength.

[0003] In order to maintain the explosion resistance of the elevator control cabinet, the cabinet door and cabinet body are usually locked together with a large number of high-strength bolts. This method makes elevator maintenance particularly troublesome, and maintenance personnel often forget or fail to tighten the door bolts, which will pose an explosion hazard if flammable gas enters the machine room.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Reference Figure 1-5An elevator control cabinet door opening device includes a control cabinet body 1, a cabinet door body 2 hinged to the outside of the control cabinet body 1, a fixing plate 3 fixedly installed on the outside of the cabinet door body 2, sliding grooves 6 at both ends of the fixing plate 3, a double-acting screw 7 rotatably connected to the inside of the fixing plate 3 between the two sliding grooves 6, and snap-fit ​​pieces 5 slidably connected to the inside of each sliding groove 6. The two snap-fit ​​pieces 5 are threadedly connected to the two ends of the double-acting screw 7, and a snap-fit ​​box 4 cooperating with the snap-fit ​​pieces 5 is fixedly connected to one side of the control cabinet body 1. The snap-fit ​​pieces 5 snap into the corresponding snap-fit ​​boxes 4. Equipped with a transmission assembly, the sliding groove 6 has a limit component inside. When the cabinet door 2 is closed, the operator can use the transmission assembly to drive the two bidirectional lead screws 7 to rotate. This allows the locking component 5 to move under the action of the limit component, thus enabling the locking component 5 to engage with the corresponding locking box 4. This achieves the purpose of quickly locking and fixing the control cabinet body 1 and the cabinet door 2. When the cabinet door 2 is opened, the bidirectional lead screws 7 are simply reversed. This method makes the opening and closing operation of the cabinet door 2 more convenient and also simplifies elevator maintenance.

[0025] Specifically, the transmission assembly includes a mounting groove 10 located in the middle of the fixed plate 3. A worm gear 11 is rotatably connected inside the mounting groove 10. The rotation of the worm gear 11 drives the worm wheel 12 to rotate, which in turn drives the corresponding bidirectional lead screw 7 to rotate, thereby realizing the transmission of power. Worm wheels 12 are rotatably installed at both ends inside the mounting groove 10, and the worm wheels 12 are meshed with the worm gear 11. The limiting assembly includes limiting grooves 8 located inside the fixed plate 3 and on both sides of the sliding groove 6. Limiting blocks 9 are slidably connected inside the limiting grooves 8. Through the cooperation of the limiting grooves 8 and the limiting blocks 9, the locking piece 5 can slide up and down in the sliding groove 6, thereby ensuring the normal operation of the cabinet door body 2 opening and closing. The two limiting blocks 9 are fixedly connected to both sides of the locking piece 5, and the worm wheel 12 is fixedly connected to the outer periphery of the corresponding bidirectional lead screw 7. Two locking clamps 15 are installed on the outside of the control cabinet body 1, which can further improve the explosion-proof strength between the control cabinet body 1 and the cabinet door body 2.

[0026] Specifically, the control cabinet body 1 and the cabinet door body 2 are fastened together by two locking clamps 15. The control cabinet body 1 is equipped with a sealing component, which includes a sealing groove 14 opened inside the control cabinet body 1. A sealing strip 13 is fixedly connected to the side of the cabinet door body 2 near the control cabinet body 1. Through the cooperation of the sealing strip 13 and the sealing groove 14, the sealing performance between the control cabinet body 1 and the cabinet door body 2 can be improved, thereby preventing water from directly entering the interior of the control cabinet body 1. The sealing groove 14 is engaged with the sealing strip 13. One end of the worm gear 11 extends to the outside of the fixing plate 3 and is fixedly connected to a handwheel, which facilitates the rotation of the worm gear 11.

[0027] Working principle: First, when closing the cabinet door body 2, the operator can use the handwheel to drive the worm gear 11 to rotate. The rotation of the worm gear 11 drives the worm wheel 12 to rotate, which in turn drives the corresponding bidirectional lead screw 7 to rotate. Then, under the action of the limit component, the locking piece 5 is pushed to move, so that the locking piece 5 is locked with the corresponding locking box 4. This achieves the purpose of quick locking and fixing between the control cabinet body 1 and the cabinet door body 2. Furthermore, through the coordinated cooperation of the sealing strip 13 and the sealing groove 14, the sealing performance between the control cabinet body 1 and the cabinet door body 2 can be improved, thereby preventing water from directly entering the interior of the control cabinet body 1. When opening the cabinet door body 2, simply reverse the worm gear 11.
