[0051] Please see Figures 1-3 The first embodiment of this utility model provides a sealing device 1, which includes a housing assembly 11 and fastening members 12 rotatably disposed on both sides of the housing assembly 11. The housing assembly 11 includes a first housing 111 and a second housing 112 rotatably connected. The housing assembly 11 is provided with a fastening member 14, and the first housing 111 and the second housing 112 are closed by the fastening member 14. When the first housing 111 and the second housing 112 are closed, the fastening member 12 can rotate to fasten with the second housing 112 to maintain the closed state of the first housing 111 and the second housing 112.

[0052] Understandably, the first embodiment of this utility model provides a sealing device 1, which has a simple structure and good sealing and waterproofing effects. The housing assembly 11 is provided with a fastening assembly 14 to fasten the first housing 111 and the second housing 112. The housing assembly 11 is also provided with a rotatable fastening member 12, which further locks the housing assembly 11 when the first housing 111 and the second housing 112 are fastened. Through the design of the fastening assembly 14 and the fastening member 12, two-level fastening positions are set on the sealing device 1, thereby enhancing the sealing effect of the sealing device 1.

[0053] Specifically, when using the sealing device 1 to close the opening of the waterproof bag, the fastener 12 can be rotated to engage with the second housing 112 to maintain the closed state of the first housing 111 and the second housing 112, that is, the closed state of the sealing device 1. This can effectively prevent the waterproof bag from being opened and water from entering when the sealing device 1 closes the opening of the waterproof bag, thus preventing damage to the electronic equipment placed inside.

[0054] It should be noted that the first housing 111 and the second housing 112 are rotatably connected. As a solution of the first embodiment of this utility model, the first housing 111 and the second housing 112 can be closed at one end of the bag opening of the sealed waterproof bag, and the connection at the other end is rotatably connected. When the first housing 111 and the second housing 112 are closed, the fastening components 12 provided on them cooperate with each other to make the housing itself fastened. Then, the fastening component 12 is rotated until the second housing 112 is fastened, thereby further locking the closed end of the first housing 111 and the second housing 112 to prevent the two from opening and closing. Through the above steps, the sealing device 1 achieves two-stage fastening.

[0055] It should be further noted that both the second housing 112 and the fastening member 12 are provided with rotating bosses 122, and the first housing 111 is provided with rotating grooves 116 corresponding to the rotating bosses 122. The rotating grooves 116 and the rotating bosses 122 are provided with connecting grooves 1161 on both sides. The rotating bosses 122 are provided with connecting holes 1221. The connecting holes 1221 are provided with rotating members 13. The rotating members 13 include an elastic body 131 and rotating shafts 132 provided at both ends of the elastic body 131. The rotating members 13 pass through the connecting holes 1221 and cooperate with the connecting grooves 1161 through the rotating shafts 132 at their ends, so that the first housing 111 is rotatably connected to the second housing 112 and / or the fastening member 12.

[0056] It should be noted that the rotating groove 116 is recessed relative to the outer wall of the first housing 111, and the rotating boss 122 is embedded in the rotating groove 116, thereby ensuring that the sealing device 1 maintains its overall flatness and aesthetics.

[0057] Please refer to the following: Figure 4 As is understandable, the fastener 12 is U-shaped in general. The inner wall of the opening 212 end of the fastener 12 is provided with a rotating boss 122. The fastener 12 is located on the side edge of the first housing 111. The rotating boss 122 on its inner wall is engaged with the rotating groove 116 on the side of the first housing 111. The fastener 12 is rotatably connected to the first housing 111 through the cooperation of the rotating member 13 with the rotating groove 116. When the fastener 12 is fastened to the second housing 112, the U-shaped fastener 12 is embedded in the side of the housing assembly 11 to maintain the cover state between the first housing 111 and the second housing 112.

[0058] In some embodiments, the elastic body 131 is specifically a spring, that is, the rotating member 13 includes a spring and two rotating shafts 132, with a rotating shaft 132 fixed at each end of the spring.

[0059] Optionally, the elastomer 131 can also be an elastic silicone rod or rubber rod, as long as it can be compressed under external force and reset after the external force is removed. The specific material or shape used in its preparation is not limited here.

[0060] In a specific embodiment, the length of the rotating member 13 is greater than the length of the rotating groove 116. When the rotating boss 122 and the rotating groove 116 are assembled, the rotating member 13 passes through the connecting hole 1221 of the rotating boss 122, and the rotating shaft 132 on the rotating member 13 is exposed at least partially from both ends of the connecting hole 1221. Since the two rotating shafts 132 of the rotating member 13 are connected by the elastic body 131, the overall length of the rotating member 13 can be compressed by applying external force to the rotating shaft 132, so that the rotating member 13 is compressed to be able to be embedded in the rotating groove 116. The rotating boss 122 through which the rotating member 13 passes is embedded into the rotating groove 116 until the rotating shaft 132 corresponds to the connecting groove 1161 on both sides of the rotating groove 116. At this time, the elastic body 131 resets under its own elastic action to send the rotating shafts 132 at both ends into the rotating groove 116, thereby realizing the rotational connection between the first housing and the second housing 112.

[0061] This design enables rapid assembly of the housing assembly 11 or the fastener 12, and after assembly, both ends of the rotating part 13 are contained within the connecting groove 1161 and not exposed, thus preventing user misoperation from causing the second housing 112 or the fastener 12 to disconnect from the first housing 111.

[0062] In addition, the rotating part 13 and the rotating groove 116 are shaft-hole mating, which is simple in structure and the shaft-hole mating structure makes it easy to hide the structure, so that the hole position is not visible on the surface of the sealing device 1, maintaining its overall flatness.

[0063] It should be further noted that the first housing 111 and the second housing 112 are rotatably connected by a rotating member 13, and the rotatable connection angle is from 0° to 180°.

[0064] Understandably, the design of the first housing 111 and the second housing 112 being rotatably connected allows the housing assembly 11 to be opened and closed away from the rotating end, making it convenient to take out electronic devices from the bag opening when the sealing device 1 is not needed to seal the opening of the waterproof bag.

[0065] Please refer to the previous document. Figure 2 Furthermore, the fastening assembly 14 includes a first fastening structure 141 and a second fastening structure 142, wherein the first fastening structure 141 and the second fastening structure 142 are engaged in a snap-fit ​​relationship; the first fastening structure 141 is disposed on the side wall of the rotating groove 116 on both sides of the first housing 111, and the second fastening structure 142 is disposed on the inner wall of the second housing 112; when the first housing 111 and the second housing 112 are closed, the first fastening structure 141 and the second fastening structure 142 are in a fastened state.

[0066] It should be noted that when the first housing 111 and the second housing 112 are closed, the first fastening structure 141 and the second fastening structure 142 cooperate with each other to seal the waterproof bag inside through mechanical locking, and the snap-locking allows the user to lock it with only the simplest operation.

[0067] As one possible implementation, the first fastening structure 141 is a groove 1122, and the second fastening structure 142 is a protrusion that cooperates with it.

[0068] Specifically, the fastening parts 12 are respectively set on both sides of the first housing 111. The symmetrical fastening design on both sides can avoid the problem of local disengagement caused by uneven force on one side. The design of multiple fastening points can also distribute the opening and closing wear to each unit, thereby improving the structural reliability and service life.

[0069] Understandably, the buckle's engagement structure is simple in design and can achieve quick engagement. In addition, as an embodiment of the present invention, the first engagement structure 141 and the second engagement structure 142 are made of plastic. Therefore, when the first housing 111 and the second housing 112 are closed, the first engagement structure 141 and the second engagement structure 142 will emit sound or vibration feedback. Through tactile and auditory feedback, users can achieve locking confirmation without visual dependence, reducing the error rate in blind operation scenarios.

[0070] Further, please refer to Figure 4 and Figure 5 The fastener 12 is provided with a protrusion 121, and the second housing 112 is provided with a groove 1122 that cooperates with the protrusion 121. The groove 1122 is provided with a ramp 1123 that slopes downward along the apex of the groove 1122 near the outer side of the fastener 12 to avoid the protrusion 121. When the fastener 12 rotates, the protrusion 121 is limited to the groove 1122 after passing through the ramp 1123.

[0071] Understandably, the snap-fit ​​engagement between the fastener 12 and the second housing 112 is achieved by the protrusion 121 being confined within the groove 1122 after passing through the ramp 1123 when the fastener 12 rotates.

[0072] It should be further explained that there is a height difference between the protrusion 121 and the sidewall of the groove 1122. When the fastener 12 rotates towards the first housing 111, it first passes through the ramp 1123 on the outside of the groove 1122, and then reaches and is confined to the groove 1122 behind the ramp 1123 to fasten the housing assembly 11. The design of the ramp 1123 assists in the fastening of the protrusion 121 and the groove 1122. Due to the height difference between the protrusion 121 and the groove 1122, the fastener 12 generates obvious feedback when it rotates to the point where the protrusion 121 and the groove 1122 are engaged, so that the user can perceive that the fastener 12 has been successfully engaged.

[0073] Specifically, the fasteners 12 are located on opposite sides of the first housing 111. When the sealing device 1 clamps the waterproof bag, it can lock the sealing device 1 to maintain its current closed state, thereby further improving the sealing effect of the sealing device 1.

[0074] Optionally, the positions of the protrusion 121 and the groove 1122 can be interchanged, that is, the protrusion 121 is disposed on the first housing 111, and the groove 1122 is disposed on the fastening member 12. In this case, the ramp 1123 is also disposed on the fastening member 12. It can be understood that the above-mentioned positional interchange is equivalent to making an equivalent substitution to the first embodiment of this utility model. Any modifications, equivalent substitutions, or improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0075] Further, please refer to Figure 2 and Figure 3 The inner walls of the first housing 111 and the second housing 112 are respectively provided with a first sealing element 1111 and a second sealing element 1121 that cooperates with the first sealing element 1111. The first sealing element 1111 and the second sealing element 1121 are disposed away from the connection end of the first housing 111 and the second housing 112.

[0076] It should be noted that when the first housing 111 and the second housing 112 are closed, the first sealing member 1111 and the second sealing member 1121 are used to keep the bag opening sealed. At this time, the first sealing member 1111 and the second sealing member 1121 are tightly fitted together, and the waterproof bag is placed between the first sealing member 1111 and the second sealing member 1121. The bag opening of the waterproof bag is sealed by the mutual cooperation of the first sealing member 1111 and the second sealing member 1121.

[0077] Specifically, the first seal 1111 and the second seal 1121 are engaged by the two being tightly fitted together when the first housing 111 and the second housing 112 are closed.

[0078] In the first embodiment of this utility model, the first sealing member 1111 and the second sealing member 1121 are specifically sealing plates. The number of the first sealing member 1111 and the second sealing member 1121 are two and one, respectively. The position between the first sealing members 1111 allows the second sealing member 1121 to be inserted, so that the three sealing plates fit tightly together to achieve the sealing operation of the waterproof bag opening. This can effectively prevent the sealing device 1 from separating from the waterproof bag, and the sealing effect is good.

[0079] Optionally, the first sealing element 1111 and the second sealing element 1121 can be one, two or more of the following: groove, sealing ring, boss and step. The specific sealing structure can be achieved by the first housing 111 and the second housing 112 cooperating with each other in this embodiment, or it can be provided only at any one of the first housing 111 and the second housing 112. It should be noted that any modifications, equivalent substitutions and improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0080] Furthermore, the first housing 111 and the second housing 112 are provided with clearance notches 113 for the fastener 12.

[0081] It should be noted that there are two fasteners 12, which are respectively set on opposite sides of the first housing 111. This design can further improve the sealing effect of the sealing device 1 when it clamps the waterproof bag to close the bag opening.

[0082] It should be further noted that the first housing 111 and the second housing 112 are provided with a notch 113 to avoid the fastener 12. The protrusion 121 on the fastener 12 can be limited to the groove 1122. That is, when the fastener 12 is fastened to the second housing 112, the flatness of the overall structure of the sealing device 1 is maintained, which can effectively prevent water from entering the waterproof bag opening due to accidental contact with the fastener 12.

[0083] Please see further. Figure 6 and Figure 7 The inner wall of the first housing 111 is provided with a fixing plate 1112. One side of the fixing plate 1112 is fixedly connected to the first housing 111, and the other side is used to attach external equipment.

The fixing plate 1112 is limited to the first housing 111 by the cooperation of the connecting protrusion 11121 and the positioning hole 1113. The positioning hole 1113 is filled with glue, thereby fixing the connecting protrusion 11121 in the positioning hole 1113. That is, the fixing plate 1112 is fixedly connected to the first housing 111 by applying glue in the hole.

[0085] It should be noted that the side of the fixing plate 1112 away from the first housing 111 is used to attach external equipment such as waterproof bags, thereby fixing the waterproof bags to the fixing plate 1112 and preventing the waterproof bags from detaching from the sealing device 1 and being lost when the sealing device 1 is opened and closed; secondly, the attachment of the waterproof bags to the fixing plate 1112 prevents the waterproof bags from shifting from the sealing device 1 when the sealing device 1 is repeatedly opened and closed, so as to ensure that the waterproof bags are completely sealed every time the sealing device 1 is closed.

[0086] As another alternative implementation, please refer to Figure 8 The first housing 111 or the second housing 112 is provided with a hanging rope 114 and a hanging rope hole 115 for the hanging rope 114 to pass through near the rotating end of the two housings. The hanging rope 114 passes through the hanging rope hole 115 through both ends of the first housing 111 or the second housing 112.

[0087] Understandably, by providing a lanyard 114 near the rotating end of the first housing 111 or the second housing 112, the lanyard 114 can be hung around the neck after passing through the lanyard hole 115, so as to carry the electronic device.

[0088] In addition, the lanyard 114 and the lanyard hole 115 through which the lanyard 114 passes can also prevent the loss of electronic devices.

[0089] It should be noted that the lanyard hole 115 can be located in the first housing 111 or the second housing 112. The lanyard 114 passes through the lanyard hole 115 at both ends of the first housing 111 or the second housing 112. The specific location of the lanyard hole 115 can be set according to the actual structure.

[0090] Specifically, the hanging rope 114 can also be fixed by the first housing 111 and the second housing 112 working together.

[0091] Optionally, a fastener 1141 can also be provided on the lanyard 114. When the lanyard 114 passes through the lanyard holes 115 at both ends of the first housing 111 and is hung around the user's neck, the fastener 1141 can prevent the lanyard 114 from falling out at the neck, thus avoiding property loss caused by the loss of the waterproof bag and the electronic devices inside the waterproof bag.

[0092] The second embodiment of this utility model also provides a waterproof bag 2 for electronic devices, including a bag body 21 and the sealing device 1 described above. One end of the bag body 21 is provided with an opening 212, and the sealing device 1 is disposed on the opening 212 to seal the opening 212.

[0093] Please see Figure 9 and Figure 10 The waterproof bag 2 for electronic devices in the second embodiment of this utility model includes the sealing device 1 provided in the first embodiment, and the waterproof bag 2 for electronic devices has the same beneficial effects as the sealing device 1 described above.

[0094] Understandably, the bag body 21 of the electronic device waterproof bag 2 has an opening 212 at one end for placing electronic devices, and the opening 212 on the bag body 21 is sealed by the sealing device 1. The first housing 111 and the second housing 112 located on opposite sides of the opening 212 close the opening 212 when they are closed, and open the opening 212 when they are separated, so as to facilitate the convenient and quick handling of electronic devices. It can also effectively prevent water from entering the bag body 21 of the electronic device waterproof bag 2 and causing damage to the electronic devices inside the bag body 21.

[0095] It should be noted that this utility model does not restrict the connection method between the sealing device 1 and the bag body 21. It can be set according to actual needs, as long as it can directly or indirectly close the opening 212 when the first shell 111 and the second shell 112 are combined, and open the opening 212 when they are separated.

[0096] It should be further noted that the waterproof bag 2 for electronic devices provided in the second embodiment of this utility model is mostly used in relatively humid environments such as bathing, swimming, rafting, and hot springs, and the electronic devices that can be placed in the bag 21 include, but are not limited to, mobile phones, tablets, digital cameras, etc.

[0097] As an optional implementation, a sealing strip 211 is provided at the opening 212 of the bag body 21, and the bag body 21 closes or opens the opening 212 through the sealing strip 211.

[0098] It should be noted that the sealing strip 211 is set on the inner wall of the bag body 21. Specifically, it is a sliding rail sealing strip 211, which allows users to quickly open and close it with one hand. The sliding rail sealing strip 211 forms a closed barrier by physical compression to effectively prevent liquid from seeping in, thereby achieving excellent waterproof and airtight performance. In addition, the sealing strip 211 can withstand a certain water pressure, so that the waterproof bag can still keep the inside dry in deep water environment.

[0099] Understandably, when the waterproof bag 2 for electronic devices needs to be sealed, the opening 212 is first sealed by the sealing strip 211 set inside the bag body 21, and then the sealing device 1 is used to seal the opening 212 of the bag body 21 a second time, thereby enhancing the waterproof effect of the waterproof bag 2 for electronic devices.

[0100] Optionally, the sealing strip 211 and the bag body 21 are designed as an integrated unit, which allows the sealing strip 211 and the bag body 21 to be seamlessly integrated, eliminating the risk of water seepage at the seams and further enhancing the waterproofness of the waterproof bag.

[0101] Preferably, the sealing strip 211 is made of high-quality silicone or other materials, so that the sealing strip 211 can withstand multiple opening and closing and can be reused.

[0102] Furthermore, the waterproof bag 2 for electronic devices includes a buoyancy structure 22, which is connected to the bag body 21.

[0103] Understandably, the buoyancy structure 22 allows the entire electronic device waterproof bag 2 to float on the water surface. This design enables users to quickly locate the waterproof bag in the water and also facilitates the easy access to and removal of electronic devices.

[0104] It should be noted that the buoyancy structure 22 is at least connected to the bag body 21. The buoyancy structure 22 can be set on the outer edge of the bag body 21 or can be directly covered on the bag body 21.

[0105] As a preferred embodiment of the second embodiment of the present invention, in the waterproof bag 2 for electronic devices, when the sealing device 1 does not close the opening 212 of the bag body 21, the shape of the bag body 21 is similar to the shape of the electronic device (e.g., mobile phone, tablet computer, etc.), that is, it includes a front and a back. A buoyancy structure 22 is provided on both the front and back of the bag body 21, and the buoyancy structure 22 is provided around the outer edge of the bag body 21.

[0106] In addition, the sealing device 1 provided in the first embodiment of this utility model is made of materials such as plastic that have a certain buoyancy. Optionally, the buoyancy structure 22 can also be set at the end of the bag body 21 where the opening 212 is away from the sealing device 1, so as to facilitate the user to position the waterproof bag. This is relatively cheaper and easier to implement.

[0107] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
