Description

Technical Field

[0001] The utility model relates to an oxygen concentrator, in particular to an oxygen storage tank fixing mechanism of the oxygen concentrator. Background Art

[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is to utilize air separation technology. Air is first compressed to a high density, then the different condensation points of its components are exploited to separate the gas and liquid at a specific temperature. This is then separated into oxygen and nitrogen through distillation. Generally, since oxygen is primarily produced, it is often referred to as an oxygen concentrator. Due to the wide range of uses for oxygen and nitrogen, oxygen concentrators are also widely used in the national economy, particularly in industries such as metallurgy, chemicals, petroleum, and defense.

[0003] The existing oxygen concentrator oxygen storage tank fixing mechanism includes a fixed side plate, a U-shaped clamp for fixing the oxygen storage tank, and bolts and nuts connecting the U-shaped clamp and the fixed side plate. In order to meet this installation structure, it is necessary to first open a through hole on the fixed side plate for the bolt to pass through. This method of pre-opening holes on the fixed side plate limits the number and installation position of the oxygen storage tank, making it difficult to install the oxygen storage tank later. Once the installation position is limited, if there is a large installation tolerance during the installation process, it will also increase the difficulty of accurate docking of the pipeline later. In addition, the bolt and nut fixing method is labor-intensive and cumbersome to install, so this improvement was born. Utility Model Content

[0004] The purpose of the utility model is to provide an oxygen storage tank fixing mechanism for an oxygen concentrator, which can realize arbitrary adjustment of the number and position of the oxygen storage tanks and is convenient to install.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an oxygen concentrator oxygen storage tank fixing mechanism, comprising: a fixed side plate; a fixed frame, which is arranged on the fixed side plate and forms an installation area with an installation opening, and the installation opening is for the oxygen storage tank to pass through and exit the installation area; a fixed component, which is arranged to form a match between the oxygen storage tank and the fixed frame in the installation area and has a fixed state and a non-fixed state for matching gravitational potential energy, when the fixed component is in the fixed state, the oxygen storage tank is restricted from moving in the direction of entering and exiting the installation opening and moving downward; when the fixed component is in the non-fixed state, the oxygen storage tank can move in the direction of the installation opening.

[0006] By adopting the above technical solution, the oxygen tank is installed into the installation area through the installation opening. The fixed assembly is then switched from a non-fixed state to a fixed state, allowing the oxygen tank to be fixed to the fixed frame by virtue of its weight potential energy. When the installation position of the oxygen tank needs to be adjusted, the fixed assembly is switched from a fixed state to a non-fixed state to achieve the movable adjustment operation of the oxygen tank. This arrangement allows for arbitrary adjustment of the number and position of the oxygen tanks, making installation more convenient.

[0007] It is further configured that: the fixing assembly includes a fixing block fixed to the oxygen storage tank, fixing teeth provided on the fixing block, and a plurality of fixing grooves provided on the fixing frame and arranged along the direction of the oxygen storage tank entering and exiting the installation opening, and the fixing teeth are inserted into the fixing grooves to limit the movement of the oxygen storage tank along the direction of the oxygen storage tank entering and exiting the installation opening and the downward movement in the vertical direction.

[0008] By adopting the above technical solution, the fixing block enters the installation area with the oxygen storage tank, and then the fixing teeth are inserted into the fixing groove to limit the horizontal movement of the oxygen storage tank. Since the fixing block is placed above the fixing groove, the oxygen storage tank will not move downward, thereby completing the installation and fixing operation of the oxygen storage tank.

[0009] It is further configured that: one end of the fixing tooth inserted into the fixing groove is provided with a guide surface for guiding the fixing tooth into the fixing groove.

[0010] By adopting the above technical solution, the setting of the guide surface is used to guide the fixing teeth to insert into the fixing groove, making the operation more convenient and smooth.

[0011] It is further configured that: an elastic pressing plate is provided on the fixed frame for pressing the oxygen storage tank to restrict it from leaving the installation area; when the fixed assembly is in a fixed state, the elastic pressing plate presses the oxygen storage tank; when the fixed assembly is in a non-fixed state, the elastic pressing plate can be separated from the oxygen storage tank.

[0012] By adopting this technical solution, the elastic retaining plate presses against the oxygen tank within the installation area, allowing the oxygen tank to be more stably fixed to the installation area. The elastic retaining plate's primary purpose is to limit the oxygen tank's upward movement, thereby enhancing installation stability. Furthermore, when the fixing assembly is in an unfixed state, the oxygen tank can be separated from the elastic retaining plate, thereby facilitating installation and adjustment of the oxygen tank.

[0013] It is further configured as follows: the elastic pressing plate is gradually inclined toward one side of the installation area, and the elastic pressing plate is extended along the direction in which the oxygen storage tank enters and exits the installation opening to form a long strip.

[0014] By adopting the above technical solution, the inclined elastic clamping plate makes the tight fitting operation between the elastic clamping plate and the oxygen storage tank more convenient, and by setting the elastic clamping plate in a long strip shape, the elastic clamping plate can play a clamping role on the oxygen storage tanks located at various positions in the installation area, thereby improving the practicality of the structure.

[0015] It is further configured that: a reinforcing frame connected to the fixed side plate is provided at a position of the fixed frame close to the installation opening.

[0016] By adopting the above technical solution, the setting of the reinforcement frame is used to improve the structural strength of the fixed frame, thereby achieving a more stable fixing effect.

[0017] It is further configured as follows: the reinforcing frame is hinged to the fixed frame so that the reinforcing frame can reciprocate toward one side of the fixed side plate, and the reinforcing frame and the fixed side plate are connected by bolts.

[0018] By adopting the above technical solution, the hinged and coordinated bolt structure realizes the movable installation of the reinforcement frame, so that the existing reinforcement frame will not interfere with the normal installation operation of the oxygen storage tank.

[0019] In summary, the present invention has the following beneficial effects: the present invention can realize arbitrary adjustment of the number and position of oxygen storage tanks and is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS
