The present invention discloses a light hyperbaric oxygen machine for pets, comprising: a pressure chamber and an oxygen generator for supplying pressurized oxygen to the pressure chamber； the present invention particularly proposes a structurally strong, transparent and durable pressure chamber. The pressure chamber comprises a transparent casing, a hatch frame and a rear deck. The door frame and the rear deck are respectively arranged at the front and the rear ends of the transparent casing. The door frame and the rear deck are made of reinforced metal material, the door frame and the rear door. The deck is connected by a plurality of metal tie rods arranged on the outer side of the transparent casing, for clamping the transparent casing tightly between the hatch frame and the rear deck, and the door is hingedly connected to the hatch frame After the door is closed, the pressure chambers are sealed by a plurality of closed bolts connecting the door frames. The positions of the closing bolts respectively correspond to the drawbars, and the force of the lock bolts and the force of the tie rods are all the same. On the axis, ensure that the door frame and rear deck structure of the pressure chamber are not damaged or deformed due to uneven force.本創作公開一種寵物用輕型高壓氧機，包括：一壓力艙和一製氧機用以對該壓力艙提供加壓氧氣；本創作特別提出一種結構強固、透明而且耐用的壓力艙，所述的壓力艙包含一透明外殼、一艙門框和一後艙板，艙門框和後艙板分別設置在透明外殼的前端和後端，艙門框和後艙板以強化的金屬材料製造，艙門框和後艙板通過平均配置在透明外殼之外側的數個金屬拉桿連接，用以將透明外殼緊緊地夾在艙門框和後艙板之間並且密合在一起，艙門藉由鉸鍊連接於艙門框，艙門關閉後藉由數個閉艙螺栓連接艙門框使壓力艙形成密閉狀態，這些閉艙螺栓的位置分別對應所述的拉桿，閉艙螺栓的作用力和拉桿的作用力皆作用在相同的軸線上，確保壓力艙的艙門框和後艙板結構不會因為受力不平均而受損或變形。
