Description

Technical Field

[0001] The utility model relates to the field of oxygen chambers, in particular to a fully transparent oxygen chamber door structure. Background Art

[0002] The micro-pressure oxygen chamber is a device with a high penetration rate. It is not only equipped in medical institutions but also applied in the health care field. The micro-pressure oxygen chamber has functions such as increasing the oxygen content in body cells, improving cell functions, relieving cell hypoxia, and activating cell functions. The application of micro-pressure oxygen chambers is increasing, especially in the health care field.

[0003] The growing demand for oxygen chamber health care also brings more problems. Traditional oxygen chambers are prefabricated in the factory and are integrally formed at one time. Their chamber doors are also made of a whole piece of steel plate. When the chamber door is closed, the interior becomes an independent airtight environment and it is impossible to observe inside and outside. The transmission of health status information of internal users completely depends on the monitoring of sensors and alarms. It is very inconvenient during use. At the same time, the airtight environment will also bring a sense of depression and fear to users. Therefore, there is an urgent need to design a see-through chamber door that does not affect the airtightness of the chamber door. The first-generation product of our company uses a bolt fixation method, which requires large holes to be drilled in the transparent door body, thus reducing the structural strength of the transparent door body. Therefore, a fully transparent oxygen chamber door structure has been redesigned. Summary of the Invention

[0004] The problem to be solved by the utility model is to propose an improved or replacement solution for the above-mentioned disadvantages in the prior art, especially an improved or replacement solution that can achieve a fully see-through effect, improve the structural strength, and not affect the airtightness effect.

[0005] To solve the above problems, the following solution is adopted in the present utility model: A fully transparent oxygen chamber door structure is provided at the inlet and outlet of a micro-pressure oxygen chamber. It is characterized in that it includes a door body main body and a chamber flange; the chamber flange is fixedly arranged at the inlet and outlet of the oxygen chamber, and a rubber sealing ring is embedded in the chamber flange; the door body main body is connected to the chamber through a hinge, and the door body main body matches the chamber flange; the door body main body includes a fully transparent door body, a door flange, an outer shell, a support ring, a locking flange and a chamber door lock; the door flange matches the chamber flange, the outer shell and the support ring are respectively fixedly connected to the door flange, and together they form a U-shaped card slot; the fully transparent door body is embedded in the U-shaped card slot; the locking flange matches the chamber flange, the locking flange is sleeved on the door flange, and the locking flange is axially positioned and circumferentially rotatable with respect to the door flange; a door lock installation notch is provided at the edge position of the fully transparent door body, and the chamber door lock is arranged in the door lock installation notch and is fixedly connected to the support ring and the outer shell; a lock catch matching the chamber door lock is provided on the locking flange; one end of the lock catch is fixed on the locking flange, and the other end is clamped with the outer handle of the door flange outside the chamber. Rotating the inner handle or the outer handle of the chamber door lock can toggle the lock catch, thereby driving the locking flange to rotate and locking the door body main body with the chamber flange.

[0006] Furthermore, for the fully transparent oxygen chamber door structure, it is characterized in that a first sealing ring is arranged between the fully transparent door body and the outer shell, and a second sealing ring is arranged between the fully transparent door body and the support ring, so as to improve the sealing performance between the fully transparent door body and the U-shaped card slot.

[0007] Furthermore, for the fully transparent oxygen chamber door structure, it is characterized in that the outer shell and the door flange, and the support ring and the door flange are fixedly connected by welding to form a firm connection.

[0008] Furthermore, for the fully transparent oxygen chamber door structure, it is characterized in that the support ring and the door flange are connected by threads, which can not only form a fixed connection structure but also facilitate later maintenance.

[0009] Furthermore, for the fully transparent oxygen chamber door structure, it is characterized in that a sealing groove is provided on the chamber flange, and the rubber sealing ring is arranged in the sealing groove; a retaining wall is provided at the outer opening of the sealing groove; the cross-section of the rubber sealing ring is in a Y-shaped structure, and the retaining wall is inserted into the fork of the Y-shaped structure.

[0010] Furthermore, for the fully transparent oxygen chamber door structure, it is characterized in that positioning grooves are provided on the locking flange, at least three positioning grooves are provided and are evenly distributed around the locking flange; positioning screws matching the positioning grooves are provided on the door flange, so that the locking flange and the door flange are relatively fixed, and the locking flange can rotate along the positioning grooves.

[0011] Further, the fully transparent oxygen chamber door structure is characterized in that the second sealing ring is provided with a groove, and the groove matches the outer edge of the fully transparent door body.

[0012] The technical effects of the present utility model are as follows: The fully transparent oxygen chamber door structure of this application adopts a structure with a transparent material in the middle and a flange on the outer ring. The flange is used to enhance the structural strength of the door. To ensure airtightness, a support ring is welded on the door flange, and the transparent door body is fixed and sealed with the support ring, rather than directly fixing and sealing the transparent door body with the door flange. Because the pressure inside the chamber is greater than the external atmospheric pressure during use, the door bears the pressure of expanding outward, and the fully transparent door body may deform. Especially when the transparent door body is made of acrylic material, if the fully transparent door body is directly fixed and sealed with the door flange, it will affect the airtightness of the door. In this application, the outer shell and the support ring are respectively fixedly connected to the door flange and jointly form a U-shaped card slot. And a first sealing ring and a second sealing ring are arranged therebetween. Even if the fully transparent door body deforms, its relative displacement with respect to the support ring is lateral displacement, which will not affect its airtightness. At the same time, a gap can be left between the fully transparent door body and the door flange to prevent the possibility of the transparent door body being damaged due to external pressure.

[0013] The locking flange is sleeved on the outside of the door flange, so that the locking flange only plays the role of locking the door body and does not directly participate in the sealing of the door. The airtightness of the door is determined by the door flange and the rubber sealing ring embedded in the chamber flange. To further improve its airtightness, the rubber sealing ring in this application is designed in a Y-shaped structure, and a retaining wall is designed at the outer opening of the sealing groove, so that the rubber sealing ring is stuck on the retaining wall to ensure 100% contact between the rubber sealing ring and the door flange, and prevent the possibility of the rubber sealing ring being locally aged and deformed and affecting the airtightness.

[0014] Compared with the first-generation transparent oxygen chamber door structure, the design scheme of this application cancels drilling and bolt fixing, ensures the structural integrity of the fully transparent door body, avoids direct collision between the fully transparent door body and the bolts, and makes the service life of the fully transparent door body longer.
