Description

A storage box Technical Field

[0001] The invention belongs to the field of storage boxes, and in particular relates to a storage box for underwear such as bra stickers or personal private items. Background Art

[0002] Existing storage boxes, especially those used to store bra stickers and other intimate underwear or personal items, generally have these problems:

[0003] 1. This type of storage box is only used to store items and has a single function; 2. After use, the bra stickers will be covered with sweat, dust, hair, bacteria, etc., and need to be cleaned after use. If not cleaned in time, the stickiness of the bra stickers will be greatly reduced. After the bra stickers are cleaned, they generally need to be dried in a place before they can be stored in the storage box. However, existing storage boxes do not have a drying function, so you need to find a hanger or a suitable place to dry the bra stickers; 3. Because bra stickers are personal items for women's private parts, it is unhygienic if there is no dedicated hanger to dry them; 4. After washing the bra stickers, if they are placed in an inappropriate position or angle, water droplets are likely to remain on the surface, making it difficult to dry them. Technical issues

[0068] In this embodiment, the upper cover connecting portion 113 is formed by the protrusion of the outer surface of the upper cover opening end face 112, and the upper cover connecting portion 113 is shaped like a stepped boss. The upper cover connecting portion 113 includes an upper cover connecting portion closing surface 1131 and an upper cover connecting portion transition surface 1132, and the upper cover connecting portion transition surface 1132 connects the upper cover connecting portion closing surface 1131 and the upper cover opening end face 112; correspondingly, the upper connecting portion 313 of the drying support member is formed by the depression of the outer surface of the upper end face 312 of the drying support member, and the upper connecting portion 313 of the drying support member is shaped like a stepped sinking platform, and the upper connecting portion 313 of the drying support member includes an upper connecting portion closing surface 3131 and an upper connecting portion transition surface 3132, and the upper connecting portion transition surface 3132 connects the upper connecting portion closing surface 3131 and the upper end face 312 of the drying support member. It is understandable that the upper cover connecting portion 113 can also be formed by a depression on the outer surface of the upper cover opening end surface 112. In this case, the upper connecting portion 313 of the drying support member can be formed by a protrusion on the outer surface of the upper end surface 312 of the drying support member.

[0069] In this embodiment, the lower cover connecting portion 213 is formed by the protrusion of the outer surface of the lower cover opening end face 212, and the lower cover connecting portion 213 is shaped like a stepped boss. The lower cover connecting portion 213 includes a lower cover connecting portion closing surface 2131 and a lower cover connecting portion transition surface 2132. The lower cover connecting portion transition surface 2132 connects the lower cover connecting portion closing surface 2131 and the lower cover opening end face 212; correspondingly, the lower connecting portion 315 of the drying support member is formed by the depression of the outer surface of the lower end face 314 of the drying support member, and the lower connecting portion 315 of the drying support member is shaped like a stepped platform. The lower connecting portion 315 of the drying support member includes a lower connecting portion closing surface 3151 and a lower connecting portion transition surface 3152. The lower connecting portion transition surface 3152 connects the lower connecting portion closing surface 3151 and the lower end face 314 of the drying support member. It can be understood that the lower cover connecting portion 213 is formed by a depression on the outer surface of the lower cover opening end surface 212, and correspondingly, the lower connecting portion 315 of the drying support member is formed by a protrusion on the outer surface of the lower end surface 314 of the drying support member.

[0070] The end of the support body 31, away from the support sleeve 32, is provided with a hanging portion 316 for hanging underwear, such as bra stickers, or other personal items. In this embodiment, the support body 31 is heart-shaped, and the hanging portion 316 is a flat-bottomed groove formed by a depression in the surface of the support body 31. This ensures that the hanging item remains balanced and prevents it from sliding. The support body 31 also has relief notches 33 on either side of the support sleeve 32 to prevent interference between the support 3 and the upper and lower covers 1 and 2.

[0071] The sleeve mechanism 4 includes a key shaft 41 and the upper cover sleeve 12, lower cover sleeve and support sleeve 32 matched therewith. The main body of the key shaft 41 is a shaft body 410 with a set length. The shaft body 410 is a cylindrical shaft body. Corresponding keys are provided at corresponding circumferential positions on the shaft body 410 for matching with the upper cover sleeve 12, lower cover sleeve and support sleeve 32. In order to facilitate the explanation and understanding of the transmission matching relationship between the key shaft 41 and the upper cover sleeve 12, lower cover sleeve and support sleeve 32, the key shaft 41 can be divided into several matching sections. As shown in Figure 18, in this embodiment, the key shaft 41 includes a lower cover sleeve matching section that matches the lower cover sleeve, an upper cover sleeve matching section 412 that matches the upper cover sleeve 12 and a support sleeve matching section 413 that matches the support sleeve 32. The upper cover 1 is rotatably connected to the upper cover sleeve adapter section of the key shaft 41 using the upper cover sleeve 12, and the lower cover 2 is rotatably connected to the lower cover sleeve adapter section of the key shaft 41 using the lower cover sleeve, so that the upper cover 1 and the lower cover 2 are rotatably connected through the key shaft 41.

[0072] The lower cover sleeve adaptation section of the key shaft 41 includes an outer lower cover sleeve adaptation section 411 adapted to the outer lower cover sleeve 22. Two outer lower cover keys are provided on the outer lower cover sleeve adaptation section 411, namely a first outer lower cover key 4111 and a second outer lower cover key 4112. The two outer lower cover keys are used to cooperate with the outer lower cover sleeve 22. The first outer lower cover key 4111 is located at 180 degrees of the circumference of the key shaft 41, and the second outer lower cover key 4112 is located at 270 degrees of the circumference of the key shaft 41.

[0073] The upper cover sleeve adapter section 412 is provided with two upper cover keys, namely the first upper cover key 4121 and the second upper cover key 4122. The two upper cover keys are used to cooperate with the upper cover sleeve 12, wherein the first upper cover key 4121 is located at 90 degrees around the key shaft 41, and the second upper cover key 4122 is located at 180 degrees around the key shaft 41.

[0074] The described support member shaft sleeve adaptation section 413 is located at 90 degrees, 180 degrees, 270 degrees or 0 degrees of the circumference of the key shaft 41, and is provided with at least one support member key 4131. The support member key 4131 is used to adapt to the support member key groove 322 of the support member shaft sleeve 32. In this embodiment, since there are four support member key grooves 322 in the support member shaft sleeve 32, four support member keys 4131 are provided on the support member shaft sleeve adaptation section 413 to adapt thereto. The four support member keys 4131 are respectively located at 0 degrees, 90 degrees, 180 degrees and 270 degrees of the circumference of the key shaft 41, so that the key shaft 41 can drive the support member 3 to rotate synchronously, and the assembly structure of the four support member keys 4131 and the four support member key grooves 322 is also more stable, reliable and durable. Understandably, the support member keyway 322 may not be provided at the 0-degree position on the circumference of the support member shaft hole, and the support member key 4131 may not be provided at the 0-degree position on the circumference of the support member sleeve adapter section 413 of the key shaft 41. The support member 3 is sleeved onto the support member sleeve adapter section of the key shaft 41 using the support member sleeve 32. Since the support member key 4131 penetrates the support member keyway 322 and forms a transmission relationship with the support member keyway 322, the support member 3 and the key shaft 41 rotate synchronously.

[0075] In this embodiment, because the lower cover shaft sleeve also includes an inner lower cover shaft sleeve 23, the key shaft 41 also includes an inner lower cover shaft sleeve adapting section 414 that adapts to the inner lower cover shaft sleeve 23, thereby making the structure between the entire shaft sleeve mechanism 4 and the drying support member 3 more compact, stable, and durable. Correspondingly, an inner lower cover key 4141 can be provided on the inner lower cover shaft sleeve adapting section 414 to adapt to the inner lower cover shaft sleeve 23. The inner lower cover key 4141 is located at a 270-degree position on the key shaft, and another inner lower cover key can be provided on the inner lower cover shaft sleeve adapting section 414 at a 180-degree position on the key shaft. In this embodiment, the inner lower cover shaft sleeve adapting section 414 does not have an inner lower cover key at a 180-degree position on the key shaft, which does not affect its use. The inner lower cover sleeve 23 is exactly the same as the outer lower cover sleeve 22, except that it is located on the inner side of the lower cover 2 closer to the center line. In this embodiment, the upper cover sleeve 12 is located between the inner lower cover sleeve 23 and the outer lower cover sleeve 22, making the structure more compact and stable.

[0076] The storage box further includes a handle 6, and the key shaft 41 further includes a handle adapting section 415 for installing the handle 6. No key is set on the handle adapting section 415, so that the handle 6 can rotate freely around the key shaft 41 without being constrained by the key.

[0077] The lock box mechanism 5 includes a lock cover fastening portion 51, a lock cover 52, and a lock cover rotating shaft portion 53. The lock cover fastening portion 51 is provided on the upper cover 1, and the lock cover rotating shaft portion 53 is provided on the lower cover 2. The lock cover rotating shaft portion 53 is provided with a lock cover rotating shaft 531. The lock cover 52 is rotatably connected to the lower cover 2 using the lock cover rotating shaft 531 on the lock cover rotating shaft portion 53. A lock cover rotating shaft hole 521 is provided at the lower portion of the lock cover 52 to match the lock cover rotating shaft 531. A lock cover buckle 522 is also provided at the upper portion of the lock cover 52 to match the lock cover fastening portion 51.

[0078] The handle 6 is provided with a handle sleeve 61 for being sleeved on the key shaft 41, and the handle sleeve 61 is provided with a handle shaft hole 611 adapted to the handle adaptation section, and the inner side wall of the handle shaft hole 611 is provided with a plurality of handle key grooves 612, which are used for allowing the key on the key shaft 41 to pass through when the key shaft 41 is installed and disassembled; in this embodiment, four handle key grooves 612 are provided on the inner side wall of the handle shaft hole 611, and are arranged in a cross shape at 0 degrees, 90 degrees, 180 degrees and 270 degrees of the circumference of the handle shaft hole 611, so that the handle 6 will not interfere with the key shaft 41 when it is sleeved and installed on the key shaft 41. The end of the handle away from the handle sleeve 61 is a free end 62. When the storage box is fully opened and the drying support 3 is in an upright state, the handle 6 is located in the gap between the upper cover 1 and the lower cover 2, and the end face of the free end 62 of the handle 6 is still a set distance h away from the end face of the upper cover or the end face of the lower cover (as shown in Figures 12 and 13). The handle will not interfere with the operation and use of the storage box at all.

[0079] In this embodiment, in order to facilitate processing and manufacturing, and to make the entire storage box structure compact, stable, reliable and durable, the key on the key shaft and the key shaft are integrally molded; the upper cover sleeve and the upper cover body are integrally molded, the lower cover sleeve and the lower cover body are integrally molded, and the drying support body and the drying support sleeve are integrally molded.

[0080] When in use, the closed position of the storage box is assumed to be the initial position, and the lower cover 2 is taken as a stationary reference. If the upper cover 1 is used to open the storage box, the angle between the upper cover 1 and the lower cover 2 is 0 degrees, and the angle between the drying support 3 and the lower cover 2 is also 0 degrees, that is, the initial position of the drying support 3 is in a horizontal position. When the upper cover 1 is opened, the lower cover 2 is in a stationary state due to its own gravity or the presence of objects such as breast stickers, causing the upper cover 1 to rotate around the key shaft 41 in the opening direction. Before the upper cover 1 rotates to the critical position, due to the presence of the upper key shaft avoidance hole 123 in the upper cover shaft sleeve 12, the upper cover 1 does not drive the key shaft 41 to rotate. When the upper cover 1 rotates to the critical position (as shown in Figure 14), the angle between the upper cover 1 and the lower cover 2 is 90 degrees. Thereafter, if the upper cover 1 continues to rotate, it will drive the key shaft 41 to rotate through the upper first rotation limit portion 124 and the first upper cover key 4121, thereby driving the drying support 3 to rotate synchronously, until the upper cover 1 rotates to the end position. At this time, the second outer lower cover key 4112 on the outer lower cover shaft sleeve adapter section 411 is abutted against the lower first rotation limit portion 224 in the outer lower cover shaft sleeve, causing the key shaft 41 to stop rotating, and the upper cover 1 and the lower cover 2 The angle between them is 180 degrees, and the storage box reaches the maximum opening angle and is in a fully open state or working state; at the same time, the supporting member 3 also rotates to its end position. At this time, the angle between the supporting member 3 and the lower cover 2 is 90 degrees (as shown in Figure 12 or 13), and the supporting member 3 reaches the maximum opening angle and is in a fully open state or working state. At this time, the supporting member 3 is in a supporting position, that is, the supporting member 3 is in an upright position. Due to the gravity of the upper cover 1 and the lower cover 2, there is a certain force arm and torque between the key shaft, and the key shaft 41 is respectively restrained by the upper first rotation limit part 124 and the lower first rotation limit part 224 and cannot rotate freely. Therefore, the supporting member 3 that rotates synchronously with the key shaft 41 cannot rotate freely and is in a stationary state or working state at the supporting position, that is, the supporting member 3 is upright supported on the storage box by the shaft sleeve mechanism 4. When the upper cover 1 or the drying support 3 is to be restored to the initial position from the end position, that is, the angle between the upper cover 1 and the lower cover 2 is to be restored from 180 degrees to 0 degrees, and the angle between the drying support 3 and the lower cover 2 is to be restored from 90 degrees to 0 degrees, the upper cover 1 can be rotated around the key shaft 41 in the closing direction. When the upper cover 1 rotates from the end position in the closing direction, it will drive the drying support 3 to rotate. When the upper cover 1 rotates and returns to the critical position, at this time, the angle between the upper cover 1 and the lower cover 2 is 90 degrees, and the drying support 3 rotates and returns to the initial position or the closed position, that is, the angle between the drying support 3 and the lower cover 2 is 0 degrees; thereafter, the upper cover 1 continues to rotate in the closing direction. At this time, the drying support 3 will remain in the closed position because it has returned to its original position. When the upper cover 1 continues to rotate to restore the angle between the upper cover 1 and the lower cover 2 to 0 degrees, it returns to the initial position, that is, the closed position.

[0081] Similarly, if the storage box is opened with the lower cover 2, the upper cover 1 is used as a stationary reference. At this time, the angle between the upper cover 1 and the lower cover 2 is 0 degrees, and the angle between the drying support 3 and the lower cover 2 is also 0 degrees, that is, the initial position of the drying support 3 is in a horizontal position. When the upper cover 1 is opened, the lower cover 2 is in a stationary state due to its own gravity or the presence of objects such as chest stickers, causing the upper cover 1 to rotate around the key shaft 41 in the opening direction. Before the upper cover 1 rotates to the critical position, due to the presence of the lower key shaft avoidance hole 223 in the lower cover shaft sleeve, the lower cover 2 does not drive the key shaft 41 to rotate. When the upper cover 1 rotates to the critical position, the angle between the lower cover and the upper cover is 90 degrees. Thereafter, if the lower cover 2 continues to rotate, it will drive the key shaft 41 to rotate through the lower first rotation limit portion 224 and the second outer lower cover key 4112, thereby driving the drying support 3 to rotate synchronously, until the lower cover 2 rotates to the end position, at which time the first upper cover key 4121 on the upper cover shaft sleeve adapter section 412 and the upper first rotation limit portion 124 in the upper cover shaft sleeve 12 abut against the key shaft 41 to stop rotating. At this time, the angle between the lower cover 2 and the upper cover 1 is 180 degrees, the storage box reaches the maximum opening angle and is in a fully open state or working state; at the same time, the support member 3 rotates to its end position, at this time the angle between the support member 3 and the lower cover 2 is 90 degrees (as shown in Figure 12 or 13), the support member 3 reaches the maximum opening angle and is in a fully open state or working state, at this time the support member 3 is in a supporting position, that is, at this time the support member 3 is in an upright position, due to the gravity of the upper cover 1 and the lower cover 2 themselves, there is a certain force arm and torque between the key shaft, and the key shaft 41 is respectively restrained by the lower first rotation limit portion 224 and the upper first rotation limit portion 124 and cannot rotate freely, so that the support member 3 that rotates synchronously with the key shaft 41 cannot rotate freely and is in a stationary state or working state in the supporting position, that is, the support member 3 is upright supported on the storage box by the shaft sleeve mechanism 4. When the lower cover 2 or the drying support 3 is to be restored to the initial position from the end position, that is, the angle between the lower cover 2 and the upper cover 1 is to be restored from 180 degrees to 0 degrees, and the angle between the drying support 3 and the lower cover 2 is to be restored from 90 degrees to 0 degrees, the lower cover 2 can be rotated around the key shaft 41 in the closing direction, and the lower cover 2 starts to rotate from the end position, which will drive the drying support 3 to rotate. When the lower cover 2 rotates and returns to the critical position, at this time, the angle between the lower cover 2 and the upper cover 1 is 90 degrees, and the drying support 3 rotates and returns to the initial position or the closed position, that is, the angle between the drying support 3 and the lower cover 2 is restored to 0 degrees; thereafter, the lower cover 2 continues to rotate in the closing direction, and at this time, the drying support 3 will remain in the closed position because it has returned to its original position. When the lower cover 2 continues to rotate to restore the angle between the lower cover 2 and the upper cover 1 to 0 degrees, it returns to the initial position, that is, the closed position.

[0082] It should be noted that when the storage box is opened, if the angle between the upper cover 1 and the lower cover 2 does not exceed 90 degrees, the drying support 3 is always in the closed position, which does not affect the removal of items such as breast stickers from the storage box or the placement of items in the storage box.
