[0030] like Figure 1 and Figure 2 As shown, the opening and closing adjustment structure of this embodiment includes: a base 10, an operating member 20, a push member 30, a limit member 40, a locking member 50 and an elastic reset member 60. The operating member 20 is rotatably arranged on the base 10. The push member 30 is arranged on the operating member 20 and moves synchronously with the operating member 20. The limit member 40 is arranged on the base 10. The locking member 50 is movably connected to the operating member 20 along a preset direction, and the locking member 50 has a locking position that is limited by the limit member 40 and a avoidance position that avoids the limit member 40. The elastic reset member 60 is arranged between the locking member 50 and the operating member 20, and applies an elastic force to the locking member 50 to keep the locking member 50 in the locked position.
[0031] The technical solution of this embodiment is applied, the operating member 20 and the limiting member 40 are arranged on the base 10, and the operating member 20 is rotatably arranged. The push member 30 is arranged on the operating member 20, and the operating member 20 drives the push member 30 to move synchronously. The locking member 50 is connected to the operating member 20, and the locking member 50 is movably arranged along a preset direction. The locking member 50 has a locking position and an avoidance position. When the locking member 50 is in the locking position, the locking member 50 and the limiting member 40 are limitedly matched. When the locking member 50 is in the avoidance position, the locking member 50 avoids the limiting member 40. An elastic reset member 60 is arranged between the locking member 50 and the operating member 20, and the elastic reset member 60 applies an elastic force to the locking member 50, so that the locking member 50 remains in the locking position. Through the above arrangement, when the locking member 50 switches from the locking position to the avoidance position, the locking member 50 moves in a preset direction, and avoids the limiter 40 while squeezing the elastic reset member 60, so that the operating member 20 can rotate relative to the base 10, and the operating member 20 can drive the locking member 50 and the push member 30 to rotate synchronously when rotating, so that when the push member 30 rotates, the box door 110 abutting against the push member 30 can rotate relative to the box body 100, that is, the opening angle of the box door 110 can be more easily adjusted. When the locking member 50 moves from the avoidance position to the locking position, the elastic reset force of the elastic reset member 60 can make the locking member 50 move relative to the operating member 20, and then the locking member 50 can cooperate with the limiter 40. Therefore, the technical solution of this embodiment effectively solves the problem that the opening angle of the box door is not easy to adjust in the related art.
[0032] like Figure 2 and Figure 3 As shown, in this embodiment, the operating member 20 includes a rod body 21, and the rod body 21 is rotatably arranged on the base 10. The locking member 50 includes a locking rod 51 connected to the rod body 21, and a first limiting portion 511 is arranged on the locking rod 51. The limiting member 40 includes a limiting plate 41 and a second limiting portion 42 arranged on the limiting plate 41, and the second limiting portion 42 is limitedly matched with the first limiting portion 511. The rotation of the rod body 21 can drive the abutting member 30 to rotate relative to the base 10. When the locking member 50 is in the locking position, the first limiting portion 511 can be limitedly matched with the second limiting portion 42, so that the locking member 50 remains stable in the locking position. When the locking member 50 is in the avoidance position, the first limiting portion 511 can avoid the second limiting portion 42, and then the locking rod 51 can rotate synchronously with the rod body 21.
[0033] like Figure 2 and Figure 3As shown, in this embodiment, the first limiting portion 511 includes a limiting block 5111, and the second limiting portion 42 includes a plurality of limiting grooves 421 arranged at intervals. When the locking member 50 is in the locked position, the limiting block 5111 is plugged and matched with one of the plurality of limiting grooves 421. By providing a plurality of limiting grooves 421, when the locking rod 51 and the rod body 21 rotate relative to the base 10, the first limiting portion 511 can be limitedly matched with one of the plurality of limiting grooves 421, so that the locking rod 51 can be switched from the avoidance position to the locking position, that is, the rod body 21 drives the push member 30 to rotate, and after the box door 110 moves with the push member 30, the relative position of the box door 110 and the box body 100 can be kept fixed, thereby realizing the adjustment of the opening angle of the box door 110.
[0034] Of course, in other embodiments, the first limiting portion 511 includes a limiting groove 421, and the second limiting portion 42 includes a plurality of limiting blocks 5111 arranged at intervals. When the locking member 50 is in the locking position, the limiting groove 421 cooperates with one of the plurality of limiting blocks 5111.
[0035] like Figure 3 As shown, in this embodiment, the limiting plate 41 is an arc-shaped plate, and the second limiting portion 42 includes a plurality of limiting grooves 421 arranged at intervals, and the distance between the axis of each limiting groove 421 and the axis of the rod body 21 is equal. Through the above arrangement, after the locking rod 51 rotates relative to the base 10, when the locking rod 51 switches from the avoidance position to the limiting position, the limiting block 5111 can be more easily inserted into one of the plurality of limiting grooves 421.
[0036] It should be noted that the plurality of limiting grooves 421 are disposed on a side of the limiting plate 41 facing the rod body 21 .
[0037] like Figures 1 to 3 As shown, in this embodiment, the operating member 20 further includes an operating cylinder 22, the operating cylinder 22 and the abutting member 30 are arranged on the rod body 21 at intervals, the first end of the locking rod 51 is movably arranged in the operating cylinder 22 along a preset direction, the elastic reset member 60 is arranged between the first end of the locking rod 51 and the cylinder bottom of the operating cylinder 22, and the second end of the locking rod 51 is a pressing end, which is arranged outside the operating cylinder 22. When the pressing end is pressed, the locking rod 51 can move relative to the rod body 21 along a preset direction, so that the first limiting portion 511 can be separated from the second limiting portion 42, that is, the locking member 50 moves from the locking position to the avoidance position. When the locking rod 51 moves along the preset direction, the first end of the locking rod 51 can compress the elastic reset member 60, so that when the locking member 50 switches from the avoidance position to the locking position, under the action of the elastic reset force of the elastic reset member 60, the first limiting portion 511 can move to the limiting cooperation with the second limiting portion 42.
[0038] It should be noted that the preset direction refers to the axial direction of the operating cylinder 22 , the axial direction of the operating cylinder 22 is perpendicular to the axial direction of the rod body 21 , and the axis of the operating cylinder 22 coincides with the axis of the locking rod 51 .
[0039] like Figure 2 As shown, in this embodiment, the locking rod 51 is provided with a first avoidance hole 512, the first limiting portion 511 is provided in the first avoidance hole 512, the operating cylinder 22 is provided with a second avoidance hole 221, the limiting plate 41 is penetrated in the first avoidance hole 512 and the second avoidance hole 221, and when the locking member 50 is in the avoidance position, the operating cylinder 22 rotates to allow the locking rod 51 to rotate relative to the limiting plate 41. The first avoidance hole 512 can avoid the limiting plate 41, and the second avoidance hole 221 can also avoid the limiting plate 41, so that the locking rod 51 and the operating cylinder 22 can rotate relative to the limiting plate 41 more smoothly. The limiting plate 41 is inserted into the first avoidance hole 512 and the second avoidance hole 221, so that the limiting plate 41 can limit the operating cylinder 22 and the locking rod 51, thereby preventing the operating cylinder 22 from moving relative to the base 10 in the axial direction of the rod body 21, and also preventing the locking rod 51 from moving relative to the base 10 in the axial direction of the rod body 21.
[0040] It should be noted that, in this embodiment, the limit block 5111 is arranged on one side of the first avoidance hole 512 close to the first end of the locking rod 51. The first avoidance hole 512 is arranged between the first end of the locking rod 51 and the second end of the locking rod 51, and the second avoidance hole 221 is arranged corresponding to the first avoidance hole 512.
[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the abutting member 30 includes a connecting rod 31 and an abutting wheel 32, the first end of the connecting rod 31 is connected to the rod body 21, the axis of the connecting rod 31 and the rod body 21 have a preset angle, and the abutting wheel 32 is connected to the second end of the connecting rod 31. The abutting wheel 32 can abut against the door 110, which is convenient for adjusting the opening angle of the door 110. The axis of the connecting rod 31 and the rod body 21 have a preset angle, so that the abutting wheel 32 connected to the second end of the connecting rod 31 is spaced from the rod body 21, which is convenient for the abutting wheel 32 and the door 110.
[0042] It should be noted that a U-shaped mounting plate is provided at the second end of the connecting rod 31, and the top wheel 32 is rotatably connected to the U-shaped mounting plate through a connecting shaft, and the axis of the top wheel 32 is arranged parallel to the axis of the rod body 21. In this way, the contact between the top wheel 32 and the box door 110 is softer, and the top wheel 32 is prevented from damaging the box door 110. The preset angle between the axis of the connecting rod 31 and the rod body 21 is between 45° and 135°, specifically, it can be 45°, 60°, 90°, 120° or 135°. In this embodiment, the preset angle is 90°.
[0043] like Figure 1 As shown, in this embodiment, the base 10 includes a base plate 11, the limiting member 40 and the resisting member 30 are respectively located on both sides of the base 10, and the elastic reset member 60 includes a spring 61. The base plate 11 allows the relative positions of the operating member 20, the resisting member 30 and the limiting member 40 to remain stable. When the locking rod 51 switches from the avoidance position to the locking position, the spring 61 can apply an elastic reset force to the locking rod 51, thereby making it easier for the locking rod 51 to move to the locking position, and under the elastic force of the spring 61, the locking rod 51 can be maintained in the locking position.
[0044] The limiting member 40 further includes a first mounting rod and a second mounting rod, wherein the first mounting rod is connected between the first end of the limiting plate 41 and the base plate 11, and the second mounting rod is connected between the second end of the limiting plate 41 and the base plate 11. In this way, there is a gap between the limiting plate 41 and the base plate 11, which facilitates the rotation of the operating cylinder 22.
[0045] like Figures 4 to 8 As shown, the accommodating device of this embodiment includes a box body 100, an opening and closing adjustment structure and a box door 110, the box door 110 is swingably arranged on the box body 100, the opening and closing adjustment structure is arranged on the box body 100 and abuts and cooperates with the box door 110, and the opening and closing adjustment structure is the above-mentioned opening and closing adjustment structure. When the above-mentioned opening and closing adjustment structure is in use, the rotation of the operating member 20 can drive the top member 30 to rotate, and the top member 30 abuts and cooperates with the box door 110, so that the box door 110 can move with the rotation of the top member 30, thereby realizing the adjustment of the opening angle of the box door 110. In addition, the elastic reset member 60 can keep the locking member 50 in the locked position, at this time, the operating member 20 cannot rotate relative to the box body 100, that is, the top member 30 cannot rotate relative to the box body 100, and then the relative position of the box door 110 and the box body 100 can remain stable. The accommodating device with the above-mentioned opening and closing adjustment structure also has the above-mentioned advantages.
[0046] It should be noted that the base plate 11 may be a partial structure of the side wall of the box body 100, or the base plate 11 may be directly connected to the side wall of the box body 100. The axis of the rod body 21 is arranged parallel to the swing axis of the box door 110.
[0047] like Figures 4 to 6 As shown, in this embodiment, part of the structure of the operating member 20 is arranged outside the box body 100, the abutting member 30 is located inside the box body 100 and abuts against the box door 110, and the base 10 is arranged on the side wall of the box body 100. Through the above arrangement, the abutting member 30 can adjust the opening angle of the box door 110 relative to the box body 100.
[0048] Figure 5 and Figure 6 The schematic diagram shows that when the push member 30 is located inside the box 100 and the box door swings toward the inside of the box. Of course, when the push member 30 is located inside the box 100, the operating cylinder 22 is rotated so that the push member 30 can also push the box door 110 to swing toward the outside of the box 100.
[0049] like Figure 7 and Figure 8 As shown, in other embodiments, the opening and closing adjustment structure is located outside the box body 100 and abuts against the box door 110. Through the above arrangement, the abutting member 30 can adjust the opening angle of the box door relative to the box body.
[0050] Figure 7 and Figure 8 A schematic diagram is shown in which the opening and closing adjustment structure is located outside the box body 100 and the box door swings toward the outside of the box body. Of course, when the opening and closing adjustment structure is located outside the box body 100, by rotating the operating cylinder 22, the push piece 30 can also push the box door 110 to swing toward the inside of the box body 100.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
