Description

Technical Field

[0001] The present application relates to the technical field of protective equipment, and in particular to a bearing lubrication mechanism for a protective door. Background Art

[0002] Protective doors, also known as protective closed doors, are protective equipment installed at the entrances and exits of civil defense projects for defense or blocking. Protective closed doors are generally set at the outermost side of the entrances and exits. When the protective door is opened, normal ventilation is guaranteed in the civil defense project. When the shock wave carries toxic gases, the protective door is closed to protect the people behind the door from being affected.

[0003] Because the existing protective doors need to be closed promptly and quickly to protect personnel, personnel are generally required to regularly apply lubricating oil to the bearings of the protective doors in order to reduce wear on the protective doors and smoothly push and pull the protective doors. However, personnel generally only apply the lubricating oil on the surface, and it is difficult for the lubricating oil to enter the rotating bearings in the protective door, resulting in poor lubrication effect and increasing the subsequent maintenance costs of personnel. Therefore, a bearing lubrication mechanism for a protective door that can automatically lubricate and has a good lubrication effect is proposed. Utility Model Content

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 6As shown, a bearing lubrication mechanism for a protective door comprises a lubrication block 2 installed on the side of a wall and a protective door body 1 installed in the lubrication block 2 by rotating through a bearing; two lubrication chambers 21 for storing lubricating liquid are provided inside the lubrication block 2, and lubrication components 3 are installed on both sides of the protective door body 1, and the two lubrication components 3 cooperate with the corresponding lubrication chambers 21; when the protective door body 1 is opened or closed, the protective door body 1 drives the two lubrication components 3 to move in the corresponding lubrication chamber 21 by rotating to a certain angle, so that one of the lubrication components 3 extends away from the lubrication chamber 21, and the other lubrication component 3 extends into the lubrication chamber 21 to squeeze the lubricating liquid in the lubrication chamber 21 to lubricate the bearing of the protective door body 1, thereby facilitating better automatic reciprocating lubrication of the protective door body 1, with good lubrication effect and strong practicality.

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 6 As shown, it should be known that a groove for installing the protective door body 1 is opened at the top of the lubricating block 2, so that the bearing can be installed in the groove of the lubricating block 2, and the bearing is sleeved on the side of the protective door body 1 to facilitate fixing and rotating the protective door body 1. The lubricating block 2 is in a circular shape as a whole, so as to better protect the rotation of the protective door body 1 and enhance the stability of the protective door body 1 during installation and rotation.

[0028] In this embodiment, Figures 2 to 5 As shown, a pair of lubrication chambers 21 are symmetrically provided inside the lubrication block 2 , and avoidance grooves 22 are provided on both sides of the inner wall of the lubrication block 2 to facilitate the rotation of the lubrication assembly 3 .

[0029] In this embodiment, Figures 2 to 5 As shown, it should be known that at least two oil outlets 23 connected to the lubrication cavity 21 are provided on the inner wall side of the lubrication block 2, and the two oil outlets 23 cooperate with the lubrication component 3 so that when the lubrication component 3 rotates, the lubricating liquid in the lubrication cavity 21 flows into the bearing of the protective door body 1 through the oil outlet 23, thereby lubricating the protective door body 1.

[0030] In this embodiment, Figures 2 to 4 As shown, it should be known that an opening 331 matching the oil outlet 23 is provided on the side of the shielding block 33, so that when the shielding block 33 slides along the inner wall of the lubricating block 2, it can correspond to the oil outlet 23 so that the lubricating liquid is squeezed from the lubrication cavity 21 and flows from the opening 331 into the bearing of the protective door body 1, thereby lubricating the protective door body 1. Subsequently, the shielding plate continues to rotate so that the opening 331 and the oil outlet 23 are misaligned, and then the shielding plate blocks the oil outlet 23. At this time, the protective door body 1 is in the extreme position, that is, it is in a fully open or fully closed state, which is convenient for lubrication.

[0031] In this embodiment, Figures 1 to 5 As shown, it should be known that the lubricating block 2 is disc-shaped, so the lubricating cavity 21 is also arranged in an arc shape, and the pushing member 32 is inserted in the lubricating cavity 21, so the pushing member 32 is also arranged in an arc shape.

[0032] In this embodiment, Figure 2 and Figure 5 As shown, the lubrication assembly 3 includes a connecting block 31, a pushing member 32 and a blocking block 33; the connecting block 31 is installed on the side of the protective door body 1 and passes through the avoidance groove 22 provided on the inner wall of the lubrication block 2 to the lubrication cavity 21, the pushing member 32 is movably installed in the lubrication cavity 21 and the side is connected to the side of the connecting block 31, the blocking block 33 is in contact with the inner wall of the lubrication block 2 and the side is connected to the side of the connecting block 31; when the protective door body 1 is opened or closed, the protective door body 1 rotates to drive the two connecting blocks 31 to rotate, and one connecting block 31 rotates to drive the pushing member 32 to slide in the lubrication cavity 21 and squeeze the lubrication cavity 2 1, so that the opening 331 on the shielding block 33 is connected with the oil outlet 23 on the lubricating chamber 21, and then the lubricating oil flows out under the squeezing of the pushing member 32 to lubricate the protective door body 1, and the other connecting block 31 rotates to carry the pushing member 32 out of the other lubricating chamber 21. When the connecting block 31 carries the other pushing member 32 out of the other lubricating chamber 21, the connecting block 31 carries the opening 331 on the other shielding block 33 and the oil outlet 23 on the other lubricating chamber 21 to connect to the shielding oil outlet 23, thereby ensuring better lubrication of the outflowing lubricating liquid.

[0033] In this embodiment, Figure 2 and Figure 5 As shown, the push member 32 includes a mounting block 321 installed on the side of the connecting block 31, and a piston block 322 elastically installed on the side of the mounting block 321; when the protective door is opened and closed, the connecting block 31 rotates and drives the mounting block 321 to squeeze the lubricating liquid in the lubrication cavity 21, and then squeezes or stretches the piston block 322 through the spring, and then the piston block 322 extends into and squeezes out the lubricating liquid to lubricate the protective door body 1.

[0034] In this embodiment, Figure 1 and Figure 6 As shown, it should be known that in order to better replenish the lubricating fluid, a refueling port 24 is provided at the top of the lubricating block 2, and the lower end of the refueling port 24 is connected to the sides of the two lubrication chambers 21. At this time, the slot at the lower end of the refueling port 24 is inclined, so that when it is opened or closed, the lubricating fluid in the smaller lubrication chamber 21 flows into the larger lubrication chamber 21 through the inclined surface, thereby facilitating more labor-saving refueling. A cover body is provided on the side of the refueling port 24, and the lower end of the cover body is in contact with the plane of the lubrication chamber 21, thereby facilitating the protection of the lubricating oil in the two lubrication chambers 21.
