[0028] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0029] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0030] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0031] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] like Figure 1-4 As shown, a civil air defense door mounting frame includes a fixed frame 1, a connecting shaft 2, a bearing 3, a connecting piece 4 and a lubrication mechanism. Both ends of the connecting shaft 2 are fixed on the fixed frame; the bearing 3 is evenly fixed on the connecting shaft; the connecting piece 4 is fixed on the bearing for connecting the door panel.

[0034] Specifically, the lubrication mechanism includes an oil storage box 51, a pressure plate 52, a delivery pipe 53, a nozzle 54, a sleeve 55, a rotating shaft 56, a rack 57, a gear 58, a rotating handle 59 and a rotating shaft positioning assembly. The oil storage box 51 is fixed on the fixed frame and is used to store lubricating oil; the pressure plate 52 can slide relative to the inner wall of the oil storage box, and limit plates 521 are fixed on both sides of the pressure plate. The inner wall of the oil storage box is provided with a slide groove 511 for the limit plates to be inserted and slided; the delivery pipe 53 is fixed on the fixed frame, and one end of the delivery pipe is connected to the oil storage box; one end of the nozzle 54 is connected to the delivery pipe, which is arranged corresponding to the bearing, and a valve is provided on the nozzle Door; sleeve 55 is fixed on the fixed frame; shaft 56 is rotatably connected to the sleeve; one end of the rack 57 is fixed on the pressure plate; gear 57 is fixed on the shaft, and the gear is engaged with the rack; the rotating handle 59 is detachably connected to the shaft. When lubrication and maintenance are required at the connection, the shaft is rotated by rotating the handle, and the rotation of the shaft drives the gear to rotate, which in turn drives the rack downward, causing the pressure plate to move downward, thereby pressing the lubricating oil in the oil storage box into the delivery pipe, and then transported to each nozzle through the delivery pipe, and the lubricating oil is dripped on each bearing to achieve lubrication and maintenance, and the operation is very convenient.

[0035] Specifically, the shaft positioning assembly includes a mounting hole 501, an elastic member 502, a push rod 503 and a ball 504. The mounting hole 501 is opened on the outer wall of the shaft; the elastic member 502 is a spring, one end of which is fixed to the bottom of the mounting hole; one end of the push rod 503 is fixed to the end of the elastic member, which can slide relative to the inner wall of the mounting hole; the ball 504 is rotatably connected to the end of the push rod, and a limiting groove for the ball to be inserted is provided on the inner wall of the sleeve. The ball is pushed into the limiting groove by the elastic member, which can play a certain self-locking role, and every time the operator rotates the handle one circle, the ball will re-enter the limiting groove, giving the operator timely feedback, so that the operator can control the amount of output lubricating oil.

[0036] In other embodiments, the lubrication mechanism also includes a connecting sleeve 591, a limiting protrusion 592, a clamping plate 593 and an elastic rubber plate 594. The connecting sleeve 591 is fixed on the rotating handle, and the rotating shaft can be inserted into it; the limiting protrusion 592 is fixed on the inner wall of the connecting sleeve, and the outer wall of the rotating shaft is provided with a groove that cooperates with the limiting protrusion; the clamping plate 593 is fixed to the bottom of the oil storage box, and it is provided with a slot, and the slot can be used for the rotating handle to be inserted into; when maintenance is not required, the rotating handle can be removed and placed at the bottom of the oil storage box to prevent the staff from rotating the rotating shaft and causing waste of lubricating oil; the elastic rubber plate 594 is fixed in the slot to prevent the rotating handle from slipping out of the slot.

[0037] In other embodiments, an oil filling tube 521 is fixed on the pressure plate 52, a sealing cap 522 is screwed to the end of the oil filling tube, an external thread is provided on the inner wall of the sealing cap, an internal thread is provided on the outer wall of the oil filling tube, and the pressure plate is provided with an oil filling hole that cooperates with the oil filling tube; when the lubricating oil in the oil storage box is used up, the sealing cap can be unscrewed and the lubricating oil can be injected into the oil storage box through the oil filling tube.

[0038] In other embodiments, the rack and gear cover are provided with a protective cover shell 11, which is fixed on the fixing frame to prevent debris from falling on the gear and rack.

[0039] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
