Technical Field
[0001] The utility model relates to a telescopic pedal of an oxygen chamber sliding door and belongs to the technical field of hyperbaric oxygen chamber structures. Background Art
[0002] At present, the door of the oxygen cabin slides back and forth in the space track opened on the ground to open and close the door. In order to adapt to the door, the ground track is usually set as an open groove with a width of about 10 cm to provide space for the door to slide horizontally. When the door is opened, the open structure of the ground track is not convenient for wheelchairs or beds to enter and exit, and it is easy to bump, jam, and even cause people to step on the air and get injured.
[0003] In view of the above defects, the existing technology has made corresponding improvements. A mainstream approach is to set a flap with a certain inclination on one side of the track. When the hatch is closed, the hatch pushes the flap to flip upward to make way for the track space. When the hatch is opened, the flap flips downward due to the angle design and its own weight, and is covered above the track space.
[0004] Although the above improvement plan has achieved certain positive effects, it also brings another problem, that is, this flap can only be spread out after the hatch is fully opened, and the flip hinge is prone to rust after long-term use, and the use effect cannot be achieved when the flexibility is insufficient. Summary of the invention
[0005] In order to solve the above problems, the utility model proposes a telescopic pedal for the sliding door of an oxygen chamber.
[0006] A telescopic pedal for an oxygen cabin sliding door is used to be arranged below an open track to close the open track after the cabin door is opened. The special feature of the pedal is that it includes a fixed base and a telescopic panel slidably connected to the fixed base through an elastic control component, and at least one side of the telescopic panel is provided with a contact slope.
[0007] Furthermore, the contact slope is arranged at an angle at one end of an initial contact position between the telescopic panel and the door when the door is closed.
[0008] Furthermore, a guide rail is provided on the surface of the fixed base, and a slider is provided on the bottom surface of the telescopic panel.
[0009] Furthermore, the elastic control component includes a tension spring, a steel wire rope and a pulley group, the tension spring is fixed at a predetermined position of the fixed base, one end of the steel wire rope is connected to the tension spring, and the other end is hung at a predetermined position of the telescopic panel via a pulley group; when the cabin door is closed, that is, the telescopic panel is in a retracted state, the tension spring and the steel wire rope apply an elastic tensioning force to the telescopic panel; when the cabin door is opened, that is, the telescopic panel is in a freely extended state, the tension spring and the steel wire rope pull the telescopic panel to its original position through the elastic tensioning force.
[0010] Furthermore, a limit lock assembly is provided between the telescopic panel and the fixed base, and the limit lock assembly includes a lock body installed at the bottom of the contact slope of the telescopic panel, and a limit lock point installed at the corresponding position of the fixed base. The structure of the lock body includes a fixed plate and a rotating paddle rotatably installed on the fixed plate, and the rotating paddle has a triggering portion that contacts the cabin door, and a locking portion that abuts and adapts to the limit lock point; the fixed plate is also provided with a limit block for limiting the rotation angle of the rotating paddle and a reset spring for resetting the rotating paddle.
[0011] Furthermore, the installation position of the lock body should ensure that when the hatch is closed, the lock body contacts the hatch earlier than the contact slope, so as to achieve the function of unlocking the door first and then closing the door.
[0012] The utility model provides a telescopic pedal for the sliding door of an oxygen chamber, which has a reasonable and simple structural design and stable and reliable operation. On the one hand, the telescopic pedal structure solves the defects of the traditional flap type pedal structure, and on the other hand, it is combined with a limit lock component to provide the security and stability of the telescopic pedal, and has extremely high practicality and safety.

DETAILED DESCRIPTION
[0019] The structural scheme and design principle of the utility model are further described in detail below with reference to the accompanying drawings.
[0020] Embodiment 1
[0021] A telescopic pedal for an oxygen cabin sliding door is arranged below an open track on the floor of the oxygen cabin. When the oxygen cabin sliding door is opened, the open track is closed. The structure comprises a fixed base 1 and a telescopic panel 2 movably mounted on the fixed base 1 via a slider 21 and a guide rail 11. The initial contact end of the telescopic panel 2 when the cabin door is closed is arranged as a contact slope 22. When the cabin door is closed, the telescopic panel 2 is driven by contacting and pushing against the contact slope 22.
[0022] An elastic control component is provided between the telescopic panel 2 and the fixed base 1, and the elastic control component is mainly composed of a tension spring 3, a steel wire rope 4 and a pulley block 5, wherein the tension spring 3 is fixed at a predetermined position of the fixed base 1, one end of the steel wire rope 4 is connected to the tension spring 3, and the other end is hung and fixed at a predetermined position of the telescopic panel 2 via the pulley block 5. The function of the elastic control component is that when the hatch drives the telescopic panel 2 to retract, the elastic tension on the telescopic panel 2 is maintained through the tension spring 3 and the steel wire rope 4; when the hatch is opened, the telescopic panel 2 is controlled to reset by the elastic tension.
[0023] A limit lock assembly is arranged between the telescopic panel 2 and the fixed base 1, and the function of the limit lock assembly is to maintain the stability of the telescopic panel 2 in the extended state, and to prevent the telescopic panel 2 from sliding due to an accidental touch. The limit lock assembly includes a lock body 6 installed at the bottom of the contact slope 22 of the telescopic panel 2, and a limit lock point 7 installed at the corresponding position of the fixed base 1. The installation position of the lock body 6 should ensure that when the door is closed, the lock body 6 contacts the door earlier than the contact slope 22, so as to realize the function of unlocking first and then closing the door. The structure of the lock body 6 includes a fixed plate 61 and a rotating paddle 62 rotatably mounted on the fixed plate 61, and the rotating paddle 62 has a triggering portion 62a that contacts the door, and a locking portion 62b that abuts against the limit lock point 7. A limit block 63 for limiting the rotation angle of the rotating paddle 62 and a reset spring 63 for resetting the rotating paddle 62 are also provided on the fixed plate 61.
[0024] The telescopic pedal of the oxygen chamber sliding door of this embodiment, its use function and action process are described as follows:
[0025] When the door is closed, the door body enters the open track along one side, and the door body first contacts the rotating paddle 62, driving the rotating paddle 62 to rotate so that its locking portion 62b is disengaged from the contact with the limit lock point 7, thereby completing the unlocking of the telescopic panel 2. Then the door body moves to contact the contact inclined surface 22 of the telescopic panel 2, and when it continues to move forward, the door body presses the contact inclined surface 22 and pushes the entire telescopic panel 2 to retract to one side of the fixed base 1. At the same time, the telescopic panel 2 pulls the wire rope 4 to put the tension spring 3 in a stretched state, thus completing the door closing action.
[0026] When the door is opened, the door first releases the lateral squeezing force on the telescopic panel 2, and the tension spring 3 is reset and contracted, driving the wire rope 4 to pull the telescopic panel 2 to stretch outward and lay flat. When the door is closed, the limit lock assembly between the telescopic panel 2 and the fixed base 1 provides a locking function, and the reset spring 63 pulls the rotating paddle 62 to reset, so that the locking portion 62b of the rotating paddle 62 is re-engaged with the limit lock point 7 on the fixed base 1 and locked. At this time, the position of the telescopic panel 2 is locked and cannot be retracted, thereby avoiding the problem of forward and backward sliding caused by accidental touch.
