Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more particularly to a pressure relief structure and a container. Background Art

[0002] A pressure relief system installed on a container door panel can perform a pressure relief operation before the door is opened. Patent No. 202323153568.0 discloses a pressure relief device and container. The pressure relief device includes a mounting frame and a cover. The mounting frame is used to securely connect to the container body around the pressure relief port, and an elastic member is fixed to one end of the cover. One end of the cover is hinged to the end of the mounting frame away from the elastic member, and the other end of the cover has a baffle. The cover can pivot between a closed position and a fully open position. During the pivoting process of the cover from the closed position to the intermediate position, the baffle abuts the elastic member, exerting a force to pivot the cover toward the mounting frame. During the pivoting process of the cover from the intermediate position to the fully open position, the baffle is spaced apart from the elastic member. The pressure relief device can cause the cover to open a small angle to release gas, after which the cover automatically returns to the closed position. It can also cause the cover to pivot away from the elastic member to quickly equalize the air pressure, thereby avoiding safety hazards caused by excessive pressure inside the container. At the same time, the opening angle of the cover is not restricted.

[0003] However, many components with the same function, including this type of pressure relief device, are generally large in size and have complex installation structures. The installation of the pressure relief window needs to be considered in advance. They have poor versatility and are difficult to modify. Utility Model Content

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] A pressure relief structure, such as Figure 3 、 Figure 4 and Figure 5 As shown, the housing 2 comprises a capping rod 3, a support plate 5, a spring 6, an ejection plate 7, a tail cap 4, a rubber sealing ring 8, a fastener 9, and a thermal insulation and breathable layer 10. The housing 2 is a circular tube-shaped base structure, divided into a base end and a tube end. An integrally formed fastener 9 is provided on the outside of the base end. This fastener 9 is an outward-expanding structure with a latching portion at its end, which abuts against the inner and outer end surfaces of the door panel. A through hole is provided in the center of the base end of the housing 2, through which the capping rod 3 passes and is inserted and inserted. The inner wall of the tube end is threaded. The capping rod 3 is positioned within the fastener 9 at the base end of the housing 2, ensuring that the capping rod 3 does not extend beyond the fastener 9 at the base end of the housing 2, preventing it from being accidentally touched. The tail cap 4 is plugged into the tube wall of the housing 2, and its outer wall is threaded. The outer wall of the tail cap 4 is also provided with an integrally formed fastener 9. The interior of the tail cap 4 is filled with a thermal insulation and breathable layer 10. The tail cap 4 is threadedly connected to the housing 2. The support plate 5 is adjustably positioned within the threaded section of the housing 2, and its outer wall is threaded. The support plate 5 is provided with a center block at one end close to the cap-pressing rod 3, and a raised mounting column at the other end, which can also be understood as a mounting handle. Correspondingly, an ejector plate 7 is provided on one side close to the seat end in the shell 2. The ejector plate 7 and the support plate 5 are connected by a spring 6, and the cap-pressing rod 3 is fixedly connected to the end face of the ejector plate 7. A hollow joint is provided at one end of the ejector plate 7 close to the support plate 5. The inner diameter of the joint is not less than the outer diameter of the center block on the support plate 5, ensuring that the two can be embedded, playing a role in guiding and strengthening the structural connection. The length of the spring 6 after pre-tightening and compression must be greater than the length of the joint to ensure the effect of the spring 6. A rubber sealing ring 8 is provided on the outer periphery of the ejector plate 7, which is pressed against the open partition at the center of the seat end of the shell 2 under the action of the spring 6.

[0034] Housing 2 features multiple ventilation holes within the contact area of the rubber sealing ring 8, ensuring a secure seal when compressed. The preload of the spring 6 can be adjusted by rotating the mounting post, and the thermally insulating breathable layer 10 enhances thermal insulation. Fasteners 9, such as screws or rivets, secure the pressure relief system to the wall. By pressing the cap rod 3, the rubber sealing ring 8 disengages from the perforated partition of housing 2, releasing air and pressure. Release the cap rod 3 to reseal and stabilize the pressure.

[0035] like Figure 1 and Figure 2 As shown, a container including the above-mentioned pressure relief structure 1 has a through hole opened on the door panel or the side panel to install the pressure relief structure 1.
