[0002] As protective equipment for the entrances and exits of civil defense projects, civil defense doors are often large in size. If they are installed with only one locking structure on the side like household doors, gaps will appear on the top and bottom sides, affecting the locking effect of the civil defense door.

[0003] Therefore, two sets of locking plates can be installed on the upper and lower sides of the air defense door. A driving component can drive multiple sets of locking plates to move simultaneously, thereby driving the upper and lower sets of locking plates to insert into the lock hole and improving the locking effect of the air defense door.

[0004] When the locking structure is driven by a set of drive components, a locking flat gearbox assembly is required to drive the locking plate to move.

[0005] The locking flat gearbox assembly changes the direction of force transmission by using a gear and rack structure. However, the gear and rack inevitably jam when meshing, which requires lubrication. Existing locking flat gearbox assemblies apply grease to the gear and rack beforehand, but it is difficult to replenish lubricating oil to the gear and rack during long-term use.

[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 3A vertical locking flat gearbox assembly with an auxiliary lubrication structure includes a locking gearbox body 1. A vertical locking gear 4 is rotatably mounted inside the locking gearbox body 1 via bearings. Rack output assemblies 5 are mounted on both the upper and lower sides of the vertical locking gear 4. A locking gearbox drive rack 2 is provided on the front side of the rack output assembly 5. The locking gearbox drive rack 2 meshes with the vertical locking gear 4. A locking gearbox cover plate 8 is fixed to the front end of the locking gearbox body 1 by screws. A lubrication assembly 3 is installed inside the locking gearbox cover plate 8. A locking gearbox base plate 6 is fixed to the rear side of the locking gearbox body 1.

[0028] The lubrication assembly 3 includes an oil reservoir 301 embedded inside the locking gearbox cover plate 8, and a duckbill valve 302 is fixed in the middle of the oil reservoir 301. A sliding groove 304 is provided on the inner side of the oil reservoir 301, and several lubrication balls 303 are rotatably installed inside the sliding groove 304.

[0029] A support groove 305 is provided at the connection between the oil storage tank 301 and the vertical locking gear 4. The vertical locking gear 4 is rotatably connected to the oil storage tank 301, and a guide groove 9 is provided on the surface of the vertical locking gear 4. The oil storage tank 301 has a hollow structure. The sliding groove 304 and the lubricating ball 303 form a semi-enclosed structure, and the lubricating ball 303 and the vertical locking gear 4 are in close contact with each other.

[0030] When adopting the above technical solution, it is particularly important to note that the round tube of the duckbill valve 302 is located outside the oil reservoir 301, while the flat tube of the duckbill valve 302 is embedded inside the oil reservoir 301. When lubricating the main body 1 of the locking gearbox, a pipe matching the size of the duckbill valve 302 is inserted into the duckbill valve 302, allowing oil to be injected into the oil reservoir 301 through the duckbill valve 302. Since one end of the flat tube is in a closed state for a long time, the lubricating oil in the oil reservoir 301 cannot leak from the duckbill valve 302. However, when injecting oil, the duckbill valve 302 can be opened through the round tube end to smoothly inject oil. After the oil reservoir 301 is injected with oil, since the lubricating ball 303 is embedded inside the sliding groove 304, the lubricating ball 303 and the lubricating oil come into contact with each other, and the oil flows vertically... During the rotation of the vertical locking gear 4, since the vertical locking gear 4 and the lubricating ball 303 are in contact with each other, the lubricating oil can be transferred from the lubricating ball 303 to the surface of the vertical locking gear 4, and then flow to the teeth of the vertical locking gear 4 through the guide groove 9 opened on the surface of the vertical locking gear 4, thereby achieving the effect of lubricating the vertical locking gear 4. It should be noted that the guide groove 9 mentioned here has a U-shaped structure and is located on the gear surface of the vertical locking gear 4. The position of the guide groove 9 is adapted to the position of the sliding groove 304. Through the lubrication component 3, oil can be injected into the oil storage tank 301 through the duckbill valve 302, and the lubricating oil can be transferred to the vertical locking gear 4 through the lubricating ball 303, thereby lubricating the vertical locking gear 4.

[0031] Specifically, such as Figure 2 and Figure 4 As shown, the rack output assembly 5 includes a guide rod 501 that passes through both the upper and lower ends of the locking gearbox body 1, and a connector 503 is fixed to the end of the guide rod 501. Limiting holes 7 are provided at the connection points of the guide rod 501 and the locking gearbox drive rack 2 with the locking gearbox body 1. A connecting plate 502 is fixed to one end of the guide rod 501 that passes through the locking gearbox body 1, and a vertical locking flat rack plate 505 is fixed to the side of the connecting plate 502 near the vertical locking gear 4. The vertical locking flat rack plate 505 is meshed with the vertical locking gear 4, and the vertical locking flat rack plate 505 is located on the rear side of the locking gearbox drive rack 2. A wear-resistant plate 506 is fixed to the inner wall of the locking gearbox body 1, and a guide groove 507 is provided at the connection point of the wear-resistant plate 506 and the connecting plate 502. A guide slider 504 is slidably connected at the connection point of the guide groove 507 and the connecting plate 502.

[0032] By adopting the above technical solution, the driving component of the locking structure is connected to the locking gearbox drive rack 2. The connecting rod enables the locking gearbox drive rack 2 to move laterally. When the locking gearbox drive rack 2 moves laterally, it drives the vertical locking gear 4 to rotate. At this time, under the action of the vertical locking gear 4, the teeth drive the two sets of vertical locking flat rack plates 505 to move vertically. Simultaneously, the vertical locking flat rack plates 505 can move in the opposite direction, causing the two sets of guide rods 501 to extend or retract simultaneously. The two sets of guide rods 501 are then connected to the upper and lower locking plates respectively via the connector 503 and the connecting rod, thus enabling... The rack and pinion output assembly 5 drives the upper and lower locking plates to move, thereby realizing the locking function of the air defense door. In order to improve the stability of the vertical locking flat rack plate 505 during movement, the vertical locking flat rack plate 505 can not only be limited by the limiting hole 7, but also by the wear-resistant plate 506, so that the vertical locking flat rack plate 505 can only slide inside the guide slide groove 507 through the guide slider 504. Through the rack and pinion output assembly 5, under the action of the locking gearbox driving rack 2, it can cooperate with the vertical locking gear 4 to drive the vertical locking flat rack plate 505 to move, thereby driving the upper and lower locking plates to move, thus realizing the locking of the air defense door.

[0033] Working principle: The drive assembly of the locking structure is connected to the lock gearbox drive rack 2. The connecting rod drives the lock gearbox drive rack 2 to move laterally. During this lateral movement, the lock gearbox drive rack 2 rotates the vertical locking gear 4. Under the action of the vertical locking gear 4, the teeth drive the two sets of vertical locking flat rack plates 505 to move vertically. Simultaneously, the vertical locking flat rack plates 505 can move in the opposite direction, causing the two sets of guide rods 501 to extend or retract simultaneously. The two sets of guide rods 501 are connected to the upper and lower locking plates respectively via the connector 503 and the connecting rod. Thus, the rack output assembly 5 drives the upper and lower locking plates to move. The movement enables the locking function of the air defense door. Since the lubricating ball 303 is embedded in the sliding groove 304, the lubricating ball 303 is in contact with the lubricating oil. During the rotation of the vertical locking gear 4, the lubricating oil can be transferred from the lubricating ball 303 to the surface of the vertical locking gear 4 and flow to the teeth of the vertical locking gear 4 through the guide groove 9 opened on the surface of the vertical locking gear 4, thereby achieving the effect of lubricating the vertical locking gear 4. When it is necessary to replenish the lubricating oil, a pipe that matches the size of the duckbill valve 302 is inserted into the inside of the duckbill valve 302, and oil can be injected into the oil storage tank 301 through the duckbill valve 302.

[0034] 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.
