[0022] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0026] like Figures 1 to 4 As shown, this application discloses a pressure-reducing assembly, including a housing 1, a pressure-reducing cavity 11 inside the housing 1, one end of the pressure-reducing cavity 11 being sealed by a cover plate 2 connected to the housing 1, a movable pressure-reducing rod 3 inside the pressure-reducing cavity 11, one end of the pressure-reducing rod 3 extending away from the cover plate 2 and passing through the pressure-reducing cavity 11 to the outside, a pressure-reducing spring 4 being sleeved on the pressure-reducing rod 3, and the pressure-reducing rod 3 compressing the pressure-reducing spring 4 when it moves away from the cover plate 2; an adjustment assembly 5 is also connected to the pressure-reducing rod 3 to adjust the compressibility of the pressure-reducing spring 4.

[0027] In this application, the pressure relief rod 3 can reciprocate within the pressure relief chamber 11, and a pressure relief spring 4 is sleeved on the pressure relief rod 3. The force on the pressure relief rod 11 can store energy in the pressure relief spring 4 by compressing it, thereby reducing the pressure on the user's shoulder and achieving the pressure relief effect. Furthermore, by adjusting the component 5, the spring is first compressed, so that the pressure relief rod 3 can store more energy when moving the same distance, further reducing the pressure on the user's shoulder and expanding the applicability of the pressure relief component, making it suitable for pressure relief of heavier weights.

[0028] The pressure relief rod 3 is connected to a baffle 31 at one end near the cover plate 2. One end of the pressure relief spring 4 can abut against the baffle 31, and the other end of the pressure relief spring 4 can abut against the adjustment component 5.

[0029] The adjusting component 5 includes an abutting member 51 that abuts against the pressure reducing spring 4 and an adjusting member 52 for adjusting the position of the abutting member 51. The adjusting member 52 can adjust the position of the abutting member 51 relative to the cover plate 2, thereby adjusting the compressibility of the pressure reducing spring 4.

[0030] Furthermore, the top surface of the abutment 51 is provided with a protrusion 53 for connecting the pressure relief spring 4. The diameter of the protrusion 53 is smaller than the diameter of the abutment 51, and at least part of the protrusion 53 is embedded in the pressure relief spring 4.

[0031] The pressure-reducing spring 4 is positioned between the baffle 31 and the abutment 51, with at least a portion of the length of the baffle 31 and the abutment 51 being greater than the diameter of the pressure-reducing spring 4. This prevents the pressure-reducing spring 4 from disengaging from the abutment of the baffle 31 and the abutment 51, thereby ensuring that the pressure-reducing spring 4 remains within the baffle 31 and the abutment 51. This allows for better storage or release of energy during the movement of the pressure-reducing rod 3, resulting in a better pressure-reducing effect. Furthermore, the protrusion 53 can position the pressure-reducing spring 4, minimizing the risk of displacement during compression and ensuring a better pressure-reducing effect.

[0032] The pressure relief rod 3 has a connecting part 32 at one end away from the cover plate 2, and a through hole 33 is provided on the connecting part 32.

[0033] The connecting part 32 and the through hole provided on the connecting part 32 facilitate the connection of the pressure relief component to the package body.

[0034] In this embodiment, the outer wall of the abutment member 51 is provided with a plurality of first protrusions 511, and the bottom end of the first protrusions 511 is provided with a first inclined surface. The side wall of the pressure relief cavity 11 is provided with a plurality of second protrusions 111, and a first groove 112 for accommodating the first protrusions 511 is formed between any two second protrusions 111. The top of the second protrusions 111 is provided with a second groove 113 for accommodating part of the first protrusions 511 and a second inclined surface for guiding the first protrusions 511 into the first groove 112. The bottom of 113 is provided with a third inclined surface that fits with the first inclined surface; the top surface of the adjusting member 52 is provided with a first tooth surface 521, and the bottom surface of the abutting member 51 is provided with a second tooth surface 513 that can mesh with the first tooth surface 521; the outer side wall of the adjusting member 52 is provided with a plurality of third protrusions 522 that can be embedded in the first groove 112; when the first tooth surface 521 and the second tooth surface 513 mesh, part of the first protrusions 511 are located above the second protrusions 111, and another part of the first protrusions 511 are located above the third protrusions 522.

[0035] The third protrusion 522 is always embedded in the first groove 112; the first protrusion 511 is embedded in the first groove 112 in the first working position, and the bottom of the first protrusion 511 abuts against the second groove 113 in the second working position; when the abutment 51 is in the first working position, the compressibility of the pressure relief spring 4 is greater than that when the abutment 51 is in the second working position.

[0036] When the first protrusion 511 is in the first working position, the second tooth surface 513 cannot engage with the first tooth surface 521. When the adjusting member 52 pushes the abutment 51 upward and the first protrusion 511 disengages from the first groove 112, under the action of gravity and the pressure relief spring 4, the abutment 51 will rotate until the first tooth surface 521 and the second tooth surface 513 engage. At this time, at least part of the first protrusion 511 is located above the second groove 112. When the adjusting member 52 is released or the adjusting member 52 is returned to the initial position, the abutment 51 will fall under the action of gravity and the pressure relief spring 4. During the falling process, the first inclined surface at the bottom of the first protrusion 511 will contact the side wall of the second groove 113, and under the guidance of the first inclined surface, the abutment 51 will rotate until the first protrusion 511 is embedded in the second groove 113, and the first protrusion 511 reaches the second working position.

[0037] When the first protrusion 511 is in the second working position, the second tooth surface 513 cannot engage with the first tooth surface 521. When the adjusting member 52 moves upward until it pushes the abutment 51 upward and the first protrusion 511 disengages from the second groove 113, under the action of gravity and the pressure relief spring 4, the abutment 51 will rotate until the first tooth surface 521 and the second tooth surface 513 engage. At this time, at least part of the first protrusion 511 is located above the first groove 112. When the adjusting member 52 is released or the adjusting member 52 is returned to the initial position, the abutment 51 will fall under the action of gravity and the pressure relief spring 4. During the falling process, the first inclined surface at the bottom of the first protrusion 511 will contact the second inclined surface on the second protrusion 111. Under the guidance of the first and second inclined surfaces, the abutment 51 will rotate until the first protrusion 511 is embedded in the first groove 112 and the first protrusion 511 reaches the first working position.

[0038] In this embodiment, there are 4 first protrusions 511, 4 first grooves 112, 4 second protrusions 111, and 4 third protrusions 522.

[0039] The bottom of the adjusting component 52 is provided with an adjusting plate 523, which can increase the contact area between the user and the adjusting component 52 during adjustment, thereby reducing the difficulty of adjustment operation and making it convenient for the user to adjust.

[0040] In other embodiments, the adjusting member 52 can be a nut that is threaded onto the pressure reducing rod 3. By rotating the adjusting member 52 and cooperating with the pressure reducing spring 4, the position of the abutment member 51 can be adjusted, thereby achieving an adjustable pressure reducing effect.

[0041] like Figure 5 As shown, a backpack is also disclosed, including a bag body 91, two shoulder straps 92 and a pressure relief component 96. The pressure relief rod 3 of the pressure relief component 96 has a connecting part 32 at one end away from the cover plate 2, and a through hole 33 is provided on the connecting part 32. The pressure relief component 96 is connected to the middle of the back of the bag body 91 through the through hole 33, and one end of the two shoulder straps 92 is connected to the bag body 91, and the other end is connected to the pressure relief component 96.

[0042] The back of the package body 91 is provided with a connecting strip 97. The connecting strip 97 passes through the through hole 33 and is fixedly connected to the package body 91, so as to achieve a better connection between the pressure relief rod 3 and the package body 91.

[0043] The backpack also includes a connecting sleeve 93, a pressure relief component 96 placed inside the connecting sleeve 93, a shoulder strap 91 connected to the connecting sleeve 93, and a pressure relief bar 3 extending from the connecting sleeve 93.

[0044] The connecting sleeve 93 shown simplifies the process of connecting the shoulder strap 91 to the pressure relief component 96 and enhances the connection effect between the pressure relief component 96 and the backpack.

[0045] Furthermore, the inner side of the back of the bag body 91 is provided with a first plate 95 for supporting the bag body 91, and the top of the outer side of the back of the bag body 91 is provided with a second plate 94. The second plate 94 is connected to the first plate 95, and the shoulder strap passes through the second plate 94 and the first plate 95.

[0046] The first plate 95 can effectively support the bag body 91, and together with the second plate 94, the top of the bag body 91 can fit well against the user's back, controlling most of the force on the pressure relief component 96 in the vertical direction, thus achieving a better pressure relief effect.
