Embodiment 1

[0036] see Figure 1-8 , the present invention provides a technical solution: an automatic opening type air pressure balance hole structure for packaging boxes, including an air pressure balance hole baffle plate 1, a clamping mechanism 2, a special-shaped cam 3, a bracket 4, a pressure safety valve 5, and a ratchet limiter Mechanism 6 and packing case air pressure balance port 13, the top of packing case air pressure balance port 13 is provided with support 4, and the top of the outer end surface of support 4 is fixedly connected with multiple groups of L-shaped frames distributed in a circular array, and multiple groups of L-shaped frames A clamping mechanism 2 is installed on the inner side of the vertical end. The side of the clamping mechanism 2 close to the bracket 4 is fixedly connected with a horizontally distributed thimble 9 . A pressure safety valve 5 is installed in the middle of the outer end surface of the bracket 4 . A special-shaped cam 3 is installed under the...

Embodiment 2

[0038] Specifically, such as figure 1 , Image 6 with Figure 7 As shown, the air pressure balance hole baffle plate 1 has a disc-shaped structure, and the air pressure balance hole baffle plate 1 and the bracket 4 form a clearance fit. The selection of the clearance fit method facilitates the gas inside the packing box to pass through the air pressure balance hole baffle plate 1 and the bracket 4. The air pressure balance hole baffle plate 1 is embedded with a sealing ring 12 on the outer periphery of the bottom. The setting of the sealing ring 12 improves the sealing performance of the connection between the air pressure balance hole baffle plate 1 and the bracket 4.

Embodiment 3

[0040] Specifically, such as figure 1 , figure 2 , Figure 4 with Figure 5 As shown, the outside of the clamping mechanism 2 is fixedly connected with a fixed limit rod 8 that runs through the L-shaped frame, wherein the inside of the L-shaped frame is located outside the fixed limit rod 8 and has an opening 10 on the bracket, and the fixed limit rod 8 And the setting of the opening 10 on the bracket facilitates the installation process between the clamping mechanism 2 and the L-shaped frame on the bracket 4, and facilitates the vertical rotation adjustment and limit processing of the clamping mechanism 2 at the same time. The top of the bracket 4 is located at the special-shaped The bottom of the cam 3 is equipped with multiple sets of support guide rails 11 distributed in a circular array, and the upper end faces of the multiple sets of support guide rails 11 are fitted with the lower end surfaces of the special-shaped cam 3. The arrangement of the support guide rails 11...

Abstract

The invention discloses an automatic opening type air pressure balance hole structure for a packaging box, which comprises an air pressure balance hole baffle plate, a clamping mechanism, a special-shaped cam, a bracket, a pressure safety valve, a ratchet limit mechanism and an air pressure balance port of a packaging box. A bracket is arranged on the top of the air pressure balance port of the packing box. In the present invention, when the left limit of the ratchet limit mechanism is rotated to the right, the air pressure balance hole baffle will press the air pressure balance port of the packing box. When the pressure in the packing box exceeds the preset pressure, the pressure safety valve will The pressure relief rod on the top will push the pawl away from the ratchet wheel, which will make the left limit of the ratchet limit mechanism to the non-left limit position, the internal pressure of the packing box will make the air pressure balance hole baffle lift up, and the air inside the packing box will It is discharged through the gap between the air pressure balance port of the packing box and the air pressure balancing hole baffle, thereby realizing the automatic opening function of the air pressure balancing port of the packing box without electric control, reducing the risk of accidental explosion of the packing box, thereby improving the safety of packing box transportation .

Description

technical field [0001] The invention relates to the technical field of sealing and transportation of large-scale equipment positive pressure packaging boxes, in particular to an automatically opening air pressure balance hole structure for packaging boxes. Background technique [0002] Many large-scale products or experimental equipment need to be placed in packaging boxes during sealed storage or transportation. By controlling environmental cleanliness, temperature, and humidity parameters, the products can be placed in the required environmental requirements to achieve product protection. Some products have strict requirements on the cleanliness of the environment. In order to ensure that the environment in the packaging box is independent and free from external environment interference, the packaging box of products with strict environmental requirements is usually fully sealed during storage or transportation, and the inside of the packaging box is filled with an appropri...
