[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 5A conveniently lubricated vertical locking control box assembly includes a control box body 1. A gear shaft 2 extends through the interior of the control box body 1. A first square hole handwheel 3 is fixedly installed at one end of the gear shaft 2, and a second square hole handwheel 4 is fixedly installed at the other end of the gear shaft 2. A drive rack 5 extends through one side of the gear shaft 2 inside the control box body 1. One end of the drive rack 5 extending out of the control box body 1 is inserted into a flat gear box assembly 6. A lubrication mechanism 7 is provided at the front end of the control box body 1. The lubrication mechanism 7 includes a mounting shell 701, which is fixedly installed at the front end of the control box body 1. A pressing plate 702 is slidably connected inside the mounting shell 701. A sponge block 703 is slidably connected to one side of the pressing plate 702 inside the mounting housing 701. An oil outlet hole 704 is provided between the mounting housing 701 and the control box 1. A sliding groove 705 is provided at the front end of the mounting housing 701. A through groove 706 is provided on one side of the sliding groove 705 at the front end of the mounting housing 701. A fixing ring 707 is fixedly installed on one side of the outer wall of the gear shaft 2 corresponding to the second square hole handwheel 4. A sleeve 708 is fixedly installed at the front end of the fixing ring 707. A first spring 709 is embedded inside the sleeve 708. A through rod 710 extends from the front end of the sleeve 708. A universal ball 711 is movably connected to the front end of the through rod 710.

[0028] By adopting the above technical solution, when the first square hole handwheel 3 or the second square hole handwheel 4 is rotated by the operator, the fixed ring 707 drives the sleeve 708 to rotate the through rod 710, thereby allowing the universal ball 711 to slide stably along the slide groove 705 of the mounting shell 701 and play a certain limiting role. When the universal ball 711 slides to the through groove 706, the first spring 709 pushes the universal ball 711 to abut against the pressing plate 702, which allows the pressing plate 702 to squeeze the sponge block 703, allowing the lubricating oil to flow out and enter the control box 1 through the oil outlet 704. This allows lubrication to be performed during the adjustment of the air defense door, avoiding excessive friction in parts such as the gear shaft 2 and the drive rack 5 inside the control box 1, and ensuring flexible operation. At the same time, it avoids the trouble of the operator having to brush or apply lubricating oil separately, improving the convenience of the entire lubrication work.

[0029] Specifically, such as Figure 5 As shown, a delivery pipe 8 is fixedly installed at the top of the mounting shell 701. A connecting mechanism 9 is provided on one side of the oil outlet 704 inside the mounting shell 701. The connecting mechanism 9 includes a squeezing block 901, which is fixedly installed on one side of the oil outlet 704 inside the mounting shell 701. A second spring 902 is fixedly installed between the mounting shell 701 and the pressing plate 702. An insertion hole 903 is opened on the inner wall of the sponge block 703 at the position corresponding to the oil outlet 704. A fixing rod 904 is fixedly installed on the outer wall of the pressing plate 702 at the position corresponding to the insertion hole 903. A rubber block 905 is fixedly installed at one end of the fixing rod 904 that passes through the insertion hole 903.

[0030] By adopting the above technical solution, one end of the L-shaped conveying pipe 8 is inserted into the mounting shell 701, and the other end passes through the air-raid shelter door, which is convenient for the staff to replenish the lubricating oil. Due to the contact of the squeezing block 901, a large amount of lubricating oil can seep out when the sponge block 703 is pressed. The second spring 902 can reset the pressing plate 702 after pressing, so that the next round of pressing can be carried out. When the pressing plate 702 is displaced, it drives the fixing rod 904 to move inside the insertion hole 903. When the sponge block 703 is pressed and the lubricating oil seeps out into the oil outlet hole 704, the rubber block 905 at the front end of the fixing rod 904 is inserted into the oil outlet hole 704 to form a piston, thereby pushing the lubricating oil inside the oil outlet hole 704 to quickly enter the control box 1.

[0031] Working principle: The gear shaft 2 is rotated by the first square hole handwheel 3 or the second square hole handwheel 4, which in turn drives the rack 5, bearings and other matching components, and triggers the flat gearbox assembly 6, thereby operating the entire air defense door. This is a conventional technology and will not be described in detail here. At the position of the second square hole handwheel 4, which is shorter than the gear shaft 2, a sponge block 703 is placed inside the fixed mounting shell 701 on the outer wall of the control box 1. The gear shaft 2 passes through the mounting shell 701 and the sponge block 703. The delivery pipe 8 passes through the mounting shell 701 and extends axially out of the outer wall of the air defense door to facilitate the injection of lubricating oil, which is then absorbed by the sponge block 703. When the second square hole handwheel 4 is rotated, the fixed ring 707 drives the sleeve 708, which causes the through rod 710 to push the universal ball 711 to slide against the slide groove 705. When it reaches the through groove 706, it is elastically pushed into the through groove 706 by the first spring 709. 6. The pressing plate 702 presses against the sponge block 703, allowing lubricating oil to enter the control box 1 through the oil outlet 704 for lubrication. The universal ball 711 can easily roll away through the through groove 706 and disengage. The fixed pressing block 901 can easily squeeze the sponge block 703, allowing a large amount of lubricating oil to flow out. The second spring 902 can allow the pressing plate 702 to reset after it is pressed and no longer resisted by the universal ball 711. The insertion hole 903 of the sponge block 703 allows the fixing rod 904 fixed to the pressing plate 702 to be inserted. The rubber block 905 fixed by the fixing rod 904 is a certain distance away from the oil outlet 704. When the pressing plate 702 moves, the sponge block 703 is squeezed and lubricating oil enters the oil outlet 704. Then the fixing rod 904 pushes the rubber block 905 into the oil outlet 704, forming a piston-driven action, allowing the lubricating oil to quickly enter the inside of the control box 1.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
