Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a sealing structure and a display device. Background Technology

[0002] Outdoor displays are widely used for outdoor advertising and electronic content display because they can be directly exposed to the outdoors to perform display tasks. The key to the long-term stable operation of outdoor displays lies in their ability to be waterproof.

[0003] Current outdoor displays typically consist of a cabinet and several display modules. A waterproof sealing structure is required between the cabinet and the display modules. There are two existing types of waterproof sealing structures: one is a front waterproof structure, which is a sealing structure set in the installation direction of the display module and the cabinet. As the display module moves towards the cabinet in the installation direction, it compresses the sealing ring between the display module and the cabinet. To achieve a stronger sealing effect, the compressive force between the display module and the cabinet is relatively high, and screws are usually required to fasten the display module and the cabinet, making it impossible to use a magnetic structure that is easier to install and remove the display module. The other is a side waterproof structure, which is a sealing structure (such as a sealing ring) set in the installation direction perpendicular to the display module and the cabinet. When the display module moves towards the cabinet in the installation direction, the sealing ring will inevitably move relative to the display module (or cabinet). To achieve a stronger sealing effect, the sliding friction between the sealing ring and the display module (or cabinet) is extremely high, which makes it extremely difficult to install and remove the display module and the cabinet. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing structure and display device to solve the problem that the current waterproof sealing structure between the display module and the cabinet is difficult to balance sealing and easy disassembly.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A sealing structure includes a first connecting portion, a second connecting portion, and a sealing element located between the two;

[0007] The sealing element includes a mounting component and a movable block. The mounting component is disposed at the first connecting portion, and the movable block is used to abut against the second connecting portion.

[0008] When the first connecting part and the second connecting part move toward each other, the movable block winds around the mounting component to form a wound sealing block, and the two sides of the wound sealing block abut against the mounting component and the second connecting part, respectively.

[0009] Preferably, the mounting component includes a fixed block and a connecting segment connected to each other, the connecting segment having the movable block provided thereon, and the fixed block being located at the first connecting portion.

[0010] Preferably, the fixing block is annular, and the inner sidewall of the fixing block is inclined to the axis of the fixing block.

[0011] Preferably, the connecting segment has a first side and a second side arranged opposite to each other, the first side of the connecting segment is provided with the movable block, and the second side of the connecting segment is arranged opposite to the fixed block.

[0012] Preferably, one end of the connecting segment is located at one end of the fixed block, and the other end of the connecting segment is provided with the movable block and extends toward the other end of the fixed block, so that the cross-section of the combination of the connecting segment and the fixed block is V-shaped.

[0013] Preferably, the fixing block has a head end and a tail end, and the tail end of the fixing block is connected to the connecting segment;

[0014] The thickness of the head end is less than the thickness of the tail end.

[0015] Preferably, the first connecting part is provided with a mounting groove, the second connecting part is provided with a sealing surface opposite to the opening of the mounting groove, the mounting component is embedded in the mounting groove, and the movable block is used to abut against the sealing surface.

[0016] Preferably, the bottom wall of the mounting groove is provided with a receiving cavity. When the first connecting part and the second connecting part move in opposite directions, the winding sealing block releases the mounting component, and the movable block rolls into the receiving cavity.

[0017] Preferably, the cross-section of the movable block is circular.

[0018] To achieve the same technical effect, this utility model also provides a display device, including the sealing structure described above.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The seal is located between the first connecting part and the second connecting part. The seal includes a mounting component and a movable block connected in sequence. The mounting component is located at the first connecting part, and the movable block is used to abut against the second connecting part. When the first connecting part and the second connecting part move towards each other, the second connecting part and the mounting component together drive the movable block to rotate and wrap around part of the mounting component to form a wound seal block. Since the wound seal block rolls relative to the mounting component or the second connecting part, the resistance fed back from the wound seal block to the mounting component and the second connecting part is smaller. As the movable block rolls, the cross-sectional area of ​​the wound seal block gradually increases. The two sides of the wound seal block abut against the remaining mounting components and the second connecting part to provide higher sealing performance. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] Example 1

[0041] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the sealing structure of this utility model is schematically illustrated, including a first connecting part 10, a second connecting part 20, and a sealing element 30 located between the two.

[0042] The sealing element 30 includes a fixed block 31, a connecting section 32, and a movable block 33 connected in sequence. The movable block 33 and the fixed block 31 are arranged opposite to each other. The fixed block 31 is located at the first connecting part 10 and provides a fixed base for the sealing element 30, and maintains the original position and posture of the connecting section 32 and the movable block 33 when not subjected to external force. The movable block 33 abuts against the second connecting part 20. When the sealing element 30 is located between the first connecting part 10 and the second connecting part 20, one side of the movable block 33 abuts against the fixed block 31. When the sealing element 30 is not located between the first connecting part 10 and the second connecting part 20 (such as when the sealing element 30 is removed separately), there is a gap between the movable block 33 and the fixed block 31.

[0043] like Figure 5 and Figure 6 When the first connecting part 10 and the second connecting part 20 move toward each other, the second connecting part 20 and the fixed block 31 drive the movable block 33 to rotate. The rotating movable block 33 winds around the connecting section 32 to form a wound sealing block 34, as shown. Figure 6 The two sides of the wound sealing block 34 abut against the fixed block 31 and the second connecting part 20 respectively. The wound sealing block 34 and the fixed block 31 are in rolling motion, which generates rolling friction. At the same time, the wound sealing block 34 and the second connecting part 20 are also in rolling motion, which also generates rolling friction. Compared with the sliding friction generated by the existing sealing structure, the rolling friction has less friction force. This makes the movement resistance brought by the wound sealing block 34 to the fixed block 31 and the second connecting part 20 less. In other words, the force required to drive the first connecting part 10 and the second connecting part 20 to move towards each other is less.

[0044] As the first connecting part 10 and the second connecting part 20 continue to move towards each other, the cross-sectional area of ​​the winding sealing block 34 gradually increases. Both sides of the winding sealing block 34 abut against the fixing block 31 and the second connecting part 20, respectively. While the distance between the first connecting part 10 and the second connecting part 20 remains constant, the compressive force between the winding sealing block 34 and the fixing block 31, and between the winding sealing block 34 and the second connecting part 20, gradually increases. This provides better sealing for the first connecting part 10 and the second connecting part 20. Of course, in this embodiment, the sealing element 30 is made of rubber or silicone, which allows for the winding and stretching of the connecting section 32. Furthermore, since one side of the winding sealing block 34 abuts against the fixing block 31, the compressive force of the winding sealing block 34 on the fixing block 31 also causes a certain deformation of the fixing block 31.

[0045] Furthermore, the first connecting part 10 is provided with a mounting groove 11, and the fixing block 31 is embedded in the mounting groove 11. The fixing block 31 and the mounting groove 11 are connected by an interference fit. Therefore, the fixing block 31 and the mounting groove 11 do not need to be connected by additional fasteners, so as to reduce the material cost of the sealing structure and simplify the production steps of the sealing structure. At the same time, the squeezing force of the winding sealing block 34 on the fixing block 31 makes the fixing block 31 tend to move towards the bottom of the mounting groove 11. This also makes the connection between the fixing block 31 and the mounting groove 11 tighter, which can prevent the fixing block 31 from accidentally separating from the mounting groove 11.

[0046] The second connecting part 20 is provided with a sealing surface 21 that is opposite to the opening of the mounting groove 11. The movable block 33 abuts against the sealing surface 21. When the first connecting part 10 and the second connecting part 20 move toward each other, the fixed block 31 and the sealing surface 21 drive the movable block 33 to rotate. The two sides of the sealing block 34 are respectively abutted against the fixed block 31 and the sealing surface 21.

[0047] The connecting segment 32 has a first surface 321 and a second surface 322 arranged opposite to each other. The first surface 321 of the connecting segment 32 is provided with a movable block 33. Of course, since the sealing element 30 is an integrally formed structure, the movable block 33 located at the end of the connecting segment 32 is a structure that protrudes from the first surface 321 of the connecting segment 32. This structure still allows one side of the movable block 33 to abut against the fixed block 31, and the other side of the movable block 33 to abut against the sealing surface 21 of the second connecting part 20. The second surface 322 of the connecting segment 32 is arranged opposite to the fixed block 31. The movable block 33 is located on the first surface 321 of the connecting segment 32, which facilitates the connecting segment 32 to give the movable block 33 a predictable direction of rotation when the first connecting part 10 and the second connecting part 20 move towards each other, so that the movable block 33 can smoothly wind around the connecting segment 32 and form a wound sealing block 34.

[0048] The cross-section of the movable block 33 is preferably circular, which facilitates the rotation of the movable block 33 under the drive of the fixed block 31 and the second connecting part 20, so as to wind around the connecting section 32 connected to the movable block 33.

[0049] Example 2

[0050] like Figure 1 and Figure 2The difference between this embodiment and Embodiment 1 is that one end of the connecting segment 32 is located at one end of the fixed block 31, and the other end of the connecting segment 32 is provided with a movable block 33 extending towards the other end of the fixed block 31, so that the cross-section of the combination of the connecting segment 32 and the fixed block 31 is V-shaped. This allows a gap to be maintained between the movable block 33 and the fixed block 31 when the sealing member 30 is not located between the first connecting portion 10 and the second connecting portion 20 (e.g., when the sealing member 30 is removed alone). With this structure, when the sealing member 30 is located between the first connecting portion 10 and the second connecting portion 20, the connecting segment 32 forces one side of the movable block 33 to abut against the second connecting portion 20.

[0051] Example 3

[0052] like Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the fixing block 31 has a head end 311 and a tail end 312. The tail end 312 of the fixing block 31 is connected to the connecting section 32. The thickness of the fixing block 31 gradually increases from the head end 311 to the tail end 312. The movable block 33 is disposed opposite to the head end 311 of the fixing block 31. When the first connecting part 10 and the second connecting part 20 just begin to move towards each other, the thinner fixing block 31 results in a smaller compressive force between the winding sealing block 34 and the fixing block 31, as well as between the winding sealing block 34 and the second connecting part 20. As the first connecting part 10... As the second connecting part 20 continues to move towards each other, the cross-sectional area of ​​the wound sealing block 34 formed by the movable block 33 winding around the connecting section 32 gradually increases. The wound sealing block 34 gradually moves to the middle or even the tail end 312 of the fixed block 31 (the thickness of the fixed block 31 also increases). The resistance fed back from the wound sealing block 34 to the first connecting part 10 and the second connecting part 20 also gradually increases. Installation and maintenance personnel can judge the winding size and degree of the wound sealing block 34 by feeling the above resistance, so as to provide a certain force feedback and improve the user experience during the installation of the first connecting part 10 and the second connecting part 20. In addition, as Figure 7 and Figure 8 During the process of the first connecting part 10 and the second connecting part 20 moving in opposite directions (disengaging from each other), the movable block 33 needs to gradually return to the beginning end 311 of the fixed block 31. The thickness of the end 312 of the fixed block 31 is greater than the thickness of the beginning end 311, which can reduce the resistance of the movable block 33 in returning to its original position. Preferably, a slope or recess is provided at the beginning end 311 of the fixed block 31, which can make the movable block 33 accurately return to the initial position of the beginning end 311 of the fixed block 31, in preparation for the next winding.

[0053] Example 4

[0054] like Figure 1 and Figure 2The difference between this embodiment and embodiment 3 is that the fixing block 31 is annular, the inner sidewall of the fixing block 31 is inclined to the axis of the fixing block 31, and the diameter of the hole at the first end 311 of the fixing block 31 is smaller than the diameter of the hole at the tail end 312 of the fixing block 31. When the fixing block 31 is placed in the mounting groove 11, since the bottom of the mounting groove 11 is a circumferential surface, the fixing block 31 placed in the mounting groove 11 will deform: the extrusion force between the first end 311 of the fixing block 31 and the mounting groove 11 is greater than the extrusion force between the tail end 312 of the fixing block 31 and the mounting groove 11. This makes the tensile force generated by the first end 311 of the fixing block 31 greater and the thickness of the first end 311 of the fixing block 31 lower, which helps to improve the user experience when the first connecting part 10 and the second connecting part 20 are installed.

[0055] Example 5

[0056] like Figures 9 to 11 As shown, the difference between this embodiment and Embodiment 1 is that the sealing structure includes a first connecting part 10, a second connecting part 20, and a sealing element 30 located between the two.

[0057] The seal 30 includes a mounting component 35 and a movable block 33. The mounting component 35 is disposed on the first connecting portion 10, and the movable block 33 is used to abut against the second connecting portion 20. The mounting component 35 has a first end 351 and a second end 352 disposed opposite to each other, and the movable block 33 is disposed on the first end 351 of the mounting component 35. When the first connecting portion 10 and the second connecting portion 20 move toward each other, the movable block 33 winds around a portion of the mounting component 35 to form a wound seal block 34. The two sides of the wound seal block 34 abut against the mounting component 35 and the second connecting portion 20, respectively. Specifically, the movable block 33 winds around the first end 351 of the mounting component 35 to the middle of the mounting component 35 to form the wound seal block 34, and the two sides of the wound seal block 34 abut against the second end 352 of the mounting component 35 and the second connecting portion 20, respectively.

[0058] The first connecting part 10 is provided with a mounting groove 11, the second connecting part 20 is provided with a sealing surface 21 that is opposite to the opening of the mounting groove 11, the mounting component 35 is embedded in the mounting groove 11, specifically, the first end 351 of the mounting component 35 abuts against one end of the mounting groove 11, the second end 352 of the mounting component 35 abuts against the other end of the mounting groove 11, and the movable block 33 is used to abut against the sealing surface 21.

[0059] Furthermore, the bottom wall of the mounting groove 11 is provided with a receiving cavity 111, which is located at one end of the bottom wall of the mounting groove 11. The inner wall of the receiving cavity 111 and the bottom wall of the mounting groove 11 can be smoothly transitioned. When the mounting component 35 is placed in the mounting groove 11, one side of the first end 351 of the mounting component 35 is opposite to the opening of the receiving cavity 111. At this time, a part of the movable block 33 is embedded in the receiving cavity 111. When the first connecting part 10 and the second connecting part 20 move in opposite directions, the winding sealing block 34 releases the first end 351 of the mounting component 35, and the movable block 33 finally rolls into the receiving cavity 111. The arrangement of the receiving cavity 111 ensures that after the first connecting part 10 and the second connecting part 20 move in opposite directions, the movable block 33 is received in the receiving cavity 111, which allows the mounting component 35 to fully recover its deformation in preparation for the next winding.

[0060] Example 6

[0061] like Figures 12 to 14 As shown, the difference between this embodiment and embodiment 5 is that, in order to reduce the resistance of the movable block 33 resetting, the thickness of the first end 351 of the mounting component 35 is less than the thickness of the second end 352 of the mounting component 35.

[0062] Example 7

[0063] like Figures 5 to 15 As shown, this embodiment provides a display device, including a housing 40, a display module 50, and a sealing structure as described above. One of the first connecting part 10 and the second connecting part 20 is disposed on the housing 40, and the other is disposed on the display module 50.

[0064] In summary, the sealing element is located between the first connecting part 10 and the second connecting part 20. The sealing element 30 includes a mounting component 35 and a movable block 33 connected in sequence. The mounting component 35 is located at the first connecting part 10, and the movable block 33 is used to abut against the second connecting part 20. When the first connecting part 10 and the second connecting part 20 move towards each other, the second connecting part 20 and the mounting component 35 jointly drive the movable block 33 to rotate and wrap around part of the mounting component 35 to form a wound sealing block 34. Since the wound sealing block 34 rolls relative to the mounting component 35 or the second connecting part 20, the resistance of the wound sealing block 34 to the mounting component 35 and the second connecting part 20 is smaller. As the movable block 33 rolls, the cross-sectional area of ​​the wound sealing block 34 gradually increases. The two sides of the wound sealing block 34 abut against the remaining mounting components 35 and the second connecting part 20 respectively to provide higher sealing performance.

[0065] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
