Description

Technical Field

[0001] This utility model relates to the technical field of storage bags, and in particular to an opening and closing mechanism and a storage bag. Background Technology

[0002] When not in use, products such as headphones, wristbands, and microphones are often stored in storage cases. These cases typically use magnetic or snap-fit ​​connections for opening and closing. However, if a storage case is accidentally dropped, the components that enable the opening and closing mechanism may separate upon impact, leaving the case permanently open. This can lead to the product falling out, becoming damaged, or being lost. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an opening and closing mechanism that can prevent the product from falling out of the storage container, thereby improving the safety of the product during storage.

[0004] This utility model also proposes a storage bag having the above-mentioned opening and closing mechanism.

[0005] The opening and closing mechanism according to a first aspect of the present invention includes at least two clamping members and a first opening and closing member.

[0006] At least two of the clamping members are spaced apart along a first direction, and each clamping member includes a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion being rotatably connected;

[0007] A first opening / closing member is connected to the first connecting portion of at least two of the clamping members. The first opening / closing member and the second connecting portion are separated along a second direction, which is perpendicular to the first direction.

[0008] The force on the first connecting part along the first direction can be transmitted to the first opening and closing member, causing the first opening and closing member to deform in the second direction toward the side opposite to the second connecting part. The first opening and closing member drives the first connecting part to rotate relative to the second connecting part, so as to realize the opening of the opening and closing mechanism.

[0009] The opening and closing mechanism according to the embodiment of this utility model has at least the following beneficial effects: The first connecting part and the second connecting part are rotatably connected, causing the included angle between them to change. When the first connecting parts of the two clamping members are subjected to a compressive force along a first direction, the two first connecting parts compress the first opening and closing member, causing the first opening and closing member to deform. The first opening and closing member drives the first connecting part to rotate, thereby opening the opening and closing mechanism. When the external force disappears, the first opening and closing member returns to its original shape, closing the opening and closing mechanism. This not only realizes the opening and closing of the mechanism but also ensures that after the external force acting on the first connecting part disappears, the first opening and closing member closes the mechanism, preventing the product from falling out due to the mechanism being in a normally open state.

[0010] According to some embodiments of the present invention, the first opening and closing member has an arc-shaped structure protruding along a second direction, and the radius of curvature of the arc-shaped structure gradually decreases towards both ends of the first opening and closing member in a first direction.

[0011] According to some embodiments of the present invention, the opening and closing mechanism further includes a second opening and closing member, the two ends of which are respectively connected to the second connecting portions of at least two clamping members. The second opening and closing member and the first opening and closing member are separated along a second direction. When the first connecting portion and the second connecting portion are subjected to force, the first opening and closing member and the second opening and closing member move in opposite directions along the second direction.

[0012] According to some embodiments of the present invention, the first opening and closing member has through holes at both ends along the second direction, the first connecting part includes a connecting page and a rotating part connected to each other, the rotating part is connected to the second connecting part, the clamping member further includes a fixing part, the fixing part is connected to the side of the connecting page facing the first opening and closing member, and the fixing part passes through the through hole.

[0013] According to some embodiments of the present invention, the fixing part includes an extension member and an abutment member. The extension member is connected to the side of the connecting page facing the first opening and closing member along a second direction. The abutment member is connected to the extension member and is parallel to the connecting page. The abutment member abuts against the first opening and closing member.

[0014] According to some embodiments of the present invention, the first opening and closing member has a first thickness along the second direction, and the connecting page and the abutting member have a spacing distance along the second direction, the spacing distance being no greater than the first thickness.

[0015] According to some embodiments of the present invention, the first opening and closing member has a first thickness along the second direction, and the first connecting portion and the second connecting portion have a second thickness along the second direction, wherein the first thickness is greater than the second thickness.

[0016] According to some embodiments of the present invention, the clamping member further includes a pressing part, which is disposed at the connection between the first connecting part and the second connecting part, and the pressing part is rotatably connected to the first connecting part and the second connecting part.

[0017] According to some embodiments of the present invention, the opening and closing mechanism further includes an elastic element, which is disposed between the first connecting portion and the second connecting portion along a second direction, and the two ends of the elastic element are respectively connected to the first connecting portion and the second connecting portion.

[0018] The storage bag according to a second aspect of the present invention includes a bag body and an opening and closing mechanism as described in any of the above embodiments.

[0019] The bag body has a bag opening and defines a first mounting cavity and a second mounting cavity. The first mounting cavity and the second mounting cavity are respectively located on both sides of the bag opening along a second direction. The first opening and closing member and part of the first connecting part of the opening and closing mechanism are located in the first mounting cavity, and part of the second connecting part is located in the second mounting cavity.

[0020] The storage bag according to the present utility model embodiment has at least the following beneficial effects: the opening and closing of the bag opening is achieved by the elastic deformation of the first opening and closing member, so that even if the storage bag falls to the ground, the first opening and closing member will return to its original state as the external force acting on the first opening and closing member disappears, thereby preventing the storage bag from being in a constantly open state, thus avoiding the situation where the product in the bag falls out of the bag opening and is damaged or lost.

[0042] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] The opening and closing mechanism of the first aspect embodiment and the storage bag of the second aspect embodiment of the present invention will be described below with reference to the accompanying drawings. It should be noted that, for ease of understanding and description, in the embodiments of the present invention, the left-right direction is indicated as the first direction, and the up-down direction is indicated as the second direction; the first direction and the second direction are perpendicular.

[0044] A first aspect of this utility model provides an opening and closing mechanism 100 for opening and closing a storage space, see reference. Figures 1 to 3As shown, the opening and closing mechanism 100 includes at least two clamping members 110 and a first opening and closing member 120. The at least two clamping members 110 are spaced apart in the left-right direction. Each clamping member 110 includes a first connecting portion 111 and a second connecting portion 114, which are rotatably connected. The two ends of the first opening and closing member 120 are respectively connected to the first connecting portions 111 of the at least two clamping members 110, meaning that both ends of the first opening and closing member 120 are connected to the first connecting portions 111. The first opening and closing member 120 and the second connecting portions 114 are spaced apart in the up-down direction. When the first connecting portions 111 at both ends of the first opening and closing member 120 are subjected to compressive force, the compressive force is transmitted to the first opening and closing member 120, causing the first opening and closing member 120 to deform in the up-down direction towards the side opposite to the second connecting portions 114. The first opening and closing member 120 then drives the first connecting portions 111 to rotate relative to the second connecting portions 114, thereby opening the opening and closing mechanism 100.

[0045] In one example, there are two clamping members 110, which are respectively connected to the two ends of the first opening / closing member 120. In other embodiments, the number of clamping members 110 can also be three, four, or other multiple features. Specifically, when the first connecting part 111 is subjected to a compressive force in the left-right direction, the two first connecting parts 111 tend to move closer to each other. At this time, the compressive force is transmitted to the first opening / closing member 120. The first opening / closing member 120 is an elastic member, and under the action of the compressive force, the first opening / closing member 120 deforms in the direction away from the second connecting part 114. Since the first connecting part 111 and the second connecting part 114 are rotatably connected, the first connecting part 111 will rotate relative to the second connecting part 114 under the deformation of the first opening / closing member 120, thereby increasing the included angle between the first connecting part 111 and the second connecting part 114. The first connecting part 111 and the first opening / closing member 120 together keep the opening / closing mechanism 100 in the open state. When the external force disappears or is less than the deformation force of the first opening and closing member 120, the first opening and closing member 120 will return to its initial shape, so that the first connecting part 111 and the second connecting part 114 return to their initial angle, so that the opening and closing mechanism 100 is in the closed state.

[0046] In related technologies, the opening and closing of the existing opening and closing mechanism 100 is often controlled by magnetic attraction or snap-fit. When the opening and closing mechanism 100 needs to be returned to the closed state, it needs to be closed manually or with external force. However, if the opening and closing mechanism 100 is dropped and subjected to impact, the connecting parts such as magnetic attraction or snap-fit ​​may separate, leaving the opening and closing mechanism 100 in a normally open state. This could cause the product to fall out of the storage space and be damaged or lost.

[0047] Compared to related technologies, the opening and closing mechanism 100 of this utility model embodiment utilizes the elastic deformation of the first opening and closing member 120 to achieve the opening and closing of the mechanism 100. When subjected to external force, the first connecting part 111 and the first opening and closing member 120 will jointly open the opening and closing mechanism 100 to realize the storage and retrieval of the product. After the external force disappears, the first opening and closing member 120 will return to its original state, causing the opening and closing mechanism 100 to close. Thus, not only is the opening and closing of the opening and closing mechanism 100 realized, but also the first opening and closing member 120 will close the opening and closing mechanism 100 after the external force acting on the first connecting part 111 disappears, preventing the opening and closing mechanism 100 from being in a normally open state and causing the product to fall out. Furthermore, the elastic deformation of the first opening and closing member 120 can improve the response speed of the opening and closing mechanism 100 to external forces. For example, when subjected to a short-duration external force such as an impact, the first opening and closing member 120 can quickly close the opening and closing mechanism 100, thereby reducing the possibility of the stored product falling out of the storage space.

[0048] In some embodiments, see Figures 1 to 3 As shown, the middle portion of the first opening / closing member 120 protrudes in the vertical direction to form an arc-shaped structure 121. The radius of curvature of the arc-shaped structure 121 gradually decreases towards both ends of the first opening / closing member 120 in the horizontal direction, that is, the degree of protrusion of the arc-shaped structure 121 gradually decreases towards both ends of the first opening / closing member 120. Specifically, the first opening / closing member 120 is a curved structure as a whole, and the direction of the curvature is the side of the first opening / closing member 120 away from the second connecting portion 114. This allows the curved structure to provide a guiding effect when the first opening / closing member 120 deforms, ensuring that the deformation direction of the first opening / closing member 120 is always the side away from the second connecting portion 114 in the vertical direction, thereby avoiding the situation where the deformation direction of the first opening / closing member 120 is incorrect, causing the opening / closing mechanism 100 to fail to open.

[0049] Furthermore, in some embodiments, see [reference] Figure 1 and Figure 3As shown, the opening and closing mechanism 100 also includes a second opening and closing member 130, which has the same shape and structure as the first opening and closing member 120. The second opening and closing member 130 is connected to the second connecting portion 114 of the two clamping members 110, and the first opening and closing member 120 and the second opening and closing member 130 are spaced apart in the vertical direction. When the clamping member 110 is subjected to force, the compressive force is distributed to the first connecting portion 111 and the second connecting portion 114, thereby causing the first opening and closing member 120 and the second opening and closing member 130 to deform. The first opening and closing member 120 and the second opening and closing member 130 move in opposite directions in the vertical direction when subjected to compressive force, that is, the deformation directions of the first opening and closing member 120 and the second opening and closing member 130 are opposite. By providing opening and closing members on the first connecting portion 111 and the second connecting portion 114 respectively, the two opening and closing members can deform together when the opening and closing mechanism 100 is opened, thereby increasing the opening speed of the opening and closing mechanism 100. Furthermore, the design of the double opening and closing components enhances the overall strength and stability of the opening and closing mechanism 100, while also more effectively dispersing stress and preventing structural damage caused by excessive concentration.

[0050] In some embodiments, see Figures 1 to 5 As shown, the first opening / closing member 120 has through holes 122 at both ends along the vertical direction, and the through holes 122 penetrate both sides of the first opening / closing member 120 along the vertical direction. The first connecting part 111 includes a connecting page 112 and a rotating part 113, wherein the second connecting part 114 has the same structure as the first connecting part 111. The first connecting part 111 and the second connecting part 114 are rotatably connected through the cooperation of the rotating part 113. The clamping member 110 includes a fixing part 115, which is connected to the side of the connecting page 112 facing the first opening / closing member 120 in the vertical direction. When the clamping member 110 and the first opening / closing member 120 are connected, the fixing part 115 passes through the through hole 122 to fix the first connecting part 111 and the first opening / closing member 120.

[0051] Specifically, both the first connecting portion 111 and the second connecting portion 114 have a connecting page 112 and a rotating position 113, with the connecting page 112 extending in the left-right direction. When the first opening / closing member 120 is connected to the first connecting portion 111, the first opening / closing member 120 is positioned between the connecting page 112 of the first connecting portion 111 and the second connecting portion 114. The connecting page 112 can limit the first opening / closing member 120 in the longitudinal (vertical) direction. At the same time, through the connection and cooperation of the fixing portion 115 and the through hole 122, the first opening / closing member 120 can be limited in the lateral direction, thereby preventing the first opening / closing member 120 from shifting its position relative to the first connecting portion 111 during deformation, which would affect the operation of the opening / closing mechanism 100.

[0052] Furthermore, in some embodiments, see [reference] Figure 5 and Figure 6 As shown, the fixing part 115 also includes an extension 116 and an abutment 117. One end of the extension 116 is connected vertically to the connecting page 112 of the first connecting part 111, and the other end is connected to the abutment 117. The abutment 117 is arranged parallel to the connecting page 112 and spaced apart. When the first opening / closing member 120 is connected to the first connecting part 111, the first opening / closing member 120 is positioned in the gap between the abutment 117 and the connecting page 112, and the first opening / closing member 120 abuts against the extension 116 and the abutment 117. Specifically, the extension 116 is vertically arranged. When the fixing part 115 passes through the through hole 122, the extension 116 abuts against the inner wall of the through hole 122, thereby limiting the lateral movement of the first opening / closing member 120. Meanwhile, the first opening and closing member 120 will abut against the connecting page 112 and the abutting member 117 on both sides along the vertical direction. Therefore, the connecting page 112 and the abutting member 117 can limit the first opening and closing member 120 in the vertical direction, thereby preventing the first opening and closing member 120 from being excessively deformed or disengaged during the movement.

[0053] Furthermore, in some embodiments, see [reference] Figures 1 to 6 As shown, the first opening / closing member 120 has a first thickness L1 along the vertical direction, and the connecting page 112 and the abutment member 117 have a vertical spacing distance H1, which is not greater than the first thickness L1. Specifically, the connecting page 112 and the abutment member 117 are spaced apart, defining a receiving space for accommodating the first opening / closing member 120. The spacing distance H1 is the height of the receiving space along the vertical direction. By ensuring that the spacing distance H1 is not greater than the first thickness L1, the relationship between the first opening / closing member 120 and the receiving space is an interference fit after the first opening / closing member 120 is accommodated in the receiving space, thereby improving the connection strength of the first opening / closing member 120. Furthermore, ensuring that the spacing distance H1 is not greater than the first thickness L1 also improves the fit between the abutment member 117 and the first opening / closing member 120, thereby increasing the friction between the abutment member 117 and the first opening / closing member 120 and reducing the slippage of the first opening / closing member 120.

[0054] It should be noted that if the opening and closing mechanism 100 includes a second opening and closing member 130, the overall structure of the second opening and closing member 130 is the same as that of the first opening and closing member 120, and the connection and fixing method of the second opening and closing member 130 and the second connecting part 114 is the same as the connection and fixing method of the first opening and closing member 120 and the first connecting part 111.

[0055] In some embodiments, see Figures 1 to 4As shown, the first opening / closing member 120 has a first thickness L1 along the vertical direction, and the first connecting portion 111 and the second connecting portion 114 each have a second thickness L2 along the vertical direction. The thicknesses of the first connecting portion 111 and the second connecting portion 114 are the same. The first thickness L1 is greater than the second thickness L2.

[0056] Specifically, when the first opening / closing member 120 deforms, the connection between the first connecting portion 111 and the second connecting portion 114 needs to be compressed so that the compressive force can be transmitted to the first opening / closing member 120. Keeping the second thickness L2 of the first connecting portion 111 and the second connecting portion 114 relatively small facilitates the response of the first connecting portion 111 to the compressive force, increasing the tendency of the first connecting portions 111 of the two clamping members 110 to move towards each other in the left-right direction. This allows the compressive force to be transmitted to the first opening / closing member 120 more quickly, causing the first opening / closing member 120 to deform rapidly and open the opening / closing mechanism 100. Furthermore, since the deformation of the first opening / closing member 120 requires the first connecting portion 111 to rotate relative to the second connecting portion 114, making the first thickness L1 greater than the second thickness L2 reduces the driving force of the first opening / closing member 120 on the first connecting portion 111, improving the opening / closing effect of the opening / closing mechanism 100. Meanwhile, the first opening and closing component 120 is the main deformation component. The first thickness L1 is at a large value, which not only enables the first opening and closing component 120 to effectively transmit force when subjected to force, but also, due to its large thickness, has a large cross-sectional area, which can better disperse stress, thereby improving the durability and reliability of the entire opening and closing mechanism 100.

[0057] In some embodiments, see Figure 5 and Figure 7 As shown, the clamping member 110 includes a pressing part 118, which is disposed at the connection between the first connecting part 111 and the second connecting part 114. The pressing part 118 is rotatably connected to the first connecting part 111 and the second connecting part 114.

[0058] Specifically, both the first connecting portion 111 and the second connecting portion 114 include a connecting page 112 and a rotating position 113. Since the first connecting portion 111 and the second connecting portion 114 are interconnected via the rotating position 113, the pressing portion 118 is connected to the rotating position 113. In this embodiment, the pressing portion 118 is connected to the rotating position 113 of the first connecting portion 111. In other embodiments, the pressing portion 118 may be connected to the rotating position 113 of the second connecting portion 114, or may be located between the rotating positions 113 of the first connecting portion 111 and the second connecting portion 114. This is as long as the first connecting portion 111 and the second connecting portion 114 can rotate relative to the pressing portion 118. By providing the pressing portion 118, the user can apply pressure to the pressing portion 118 to control the opening and closing of the clamping member 110. Since the first connecting part 111 and the second connecting part 114 rotate relative to each other during the opening and closing process of the opening and closing mechanism 100, the pressing part 118 can prevent the rotating part 113 from rubbing against the user's hand when the first connecting part 111 rotates relative to the second connecting part 114, thus affecting the opening and closing of the clamping part 110.

[0059] In some embodiments, see Figure 1 and Figure 8 As shown, the opening and closing mechanism 100 also includes an elastic element 140, which is disposed between the first connecting part 111 and the second connecting part 114 in the vertical direction. The two ends of the elastic element 140 are respectively connected to the first connecting part 111 and the second connecting part 114.

[0060] Specifically, during the opening and closing process of the opening and closing mechanism 100, the elastic element 140 provides necessary cushioning. When the opening and closing mechanism 100 is subjected to a sudden impact (such as falling or hitting), the elastic element 140 can act as a buffer, reducing the impact of external impacts and vibrations on the opening and closing mechanism 100. Furthermore, when the opening and closing mechanism 100 is in the open state, the included angle between the first connecting part 111 and the second connecting part 114 increases, causing the elastic element 140 to be in a stretched state. When the opening and closing mechanism 100 needs to change from the open state to the closed state, the elastic potential energy of the elastic element 140 can help the first connecting part 111 and the second connecting part 114 return to their initial positions. This not only enhances the reliability and durability of the opening and closing mechanism 100 for repeated use, but also enables the opening and closing mechanism 100 to close quickly, thereby further reducing the risk of items falling out of the storage space.

[0061] A second aspect of this utility model provides a storage bag 200, see reference. Figures 1 to 10As shown, the storage bag 200 includes a bag body 210 and an opening / closing mechanism 100 as described in any of the above embodiments. The bag body 210 has a bag opening 211, which is an opening communicating with the storage space inside the bag body 210. The bag body 210 also defines a first mounting cavity 212 and a second mounting cavity 213, which are mounted vertically on both sides of the bag opening 211. A first opening / closing member 120 and a portion of a first connecting portion 111 of the opening / closing mechanism 100 are disposed in the first mounting cavity 212, and a portion of a second connecting portion 114 is mounted in the second mounting cavity 213.

[0062] Specifically, in one example, the first mounting cavity 212 and the second mounting cavity 213 are disposed on both sides of the bag opening 211 along the direction of deformation of the first opening / closing member 120. The first mounting cavity 212 and the second mounting cavity 213 respectively guide the bag body 210 to form an opening in the left-right direction. When the opening / closing mechanism 100 is connected to the bag body 210, the first opening / closing member 120 is accommodated in the first mounting cavity 212. Since the first connecting portion 111 of the two clamping members 110 needs to be squeezed to deform the first opening / closing member 120 when using the storage bag 200, it is necessary to place part of the first connecting portion 111 and the second connecting portion 114 outside the first mounting cavity 212 and the second mounting cavity 213 for the convenience of the user.

[0063] The storage bag 200 of this utility model opens and closes its opening 211 through the elastic deformation of the first opening and closing member 120. This ensures that even if the storage bag 200 falls to the ground, the first opening and closing member 120 returns to its original shape as the external force acting on it disappears. This prevents the storage bag 200 from remaining permanently open, thus avoiding the product inside the bag 210 from falling out of the opening 211 and causing damage or loss. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model. Furthermore, the embodiments and features of this utility model can be combined with each other without conflict.
