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;

[0007] The sealing element includes a fixed section, a connecting section, and a movable block connected in sequence. The sealing element is located between the first connecting part and the second connecting part, and the two sides of the movable block abut against the first connecting part and the second connecting part, respectively.

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

[0009] Preferably, the fixed segment is fixedly connected to the first connecting part.

[0010] Preferably, the connecting segment has a head end and a tail end, the head end of the connecting segment is provided with the movable block, and the tail end of the connecting segment is connected to the fixed segment;

[0011] The thickness of the first end of the connecting segment is greater than the thickness of the last end.

[0012] Preferably, the connecting segment has a first segment block and a second segment block connected to each other, the end of the first segment block is provided with the movable block, the end of the second segment block is connected to the fixed segment, and the extension directions of the first segment block and the second segment block are inclined to each other so that the cross-section of the connecting segment is V-shaped.

[0013] Preferably, the first connecting portion is provided with a mounting groove, and the fixing segment is embedded in the mounting groove.

[0014] Preferably, the fixing section and the mounting groove are connected by an interference fit.

[0015] Preferably, the second connecting part is provided with a receiving cavity, and after the first connecting part passes through the receiving cavity, there is a gap between the two, and the movable block and part or all of the connecting section are located in the gap.

[0016] Preferably, the cross-section of the movable block is circular.

[0017] Preferably, the seal is made of rubber or silicone.

[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 fixed section, a connecting section and a movable block connected in sequence. The two sides of the movable block abut against the first connecting part and the second connecting part respectively. When the first connecting part and the second connecting part move towards each other, they drive the movable block to rotate and wrap around the connecting section to form a wound seal block. Since the wound seal block rolls relative to the first connecting part or the second connecting part, the resistance fed back to the first connecting part and the second connecting part by the wound seal block 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 first connecting part and the second connecting part respectively 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.

[0034] Example 1

[0035] Combination Figure 1 , Figure 2 as well as 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 member 30. The sealing member 30 is located between the first connecting part 10 and the second connecting part 20. The sealing member 30 may be connected to the first connecting part 10, or connected to the second connecting part 20, or connected to other structures other than the first connecting part 10 and the second connecting part 20. In this embodiment, the sealing member 30 is located between the first connecting part 10 and the second connecting part 20 and provides a seal for the first connecting part 10 and the second connecting part 20.

[0036] like Figure 1 and Figure 5 As shown, the sealing element 30 includes a fixed section 31, a connecting section 32, and a movable block 33 connected in sequence. The fixed section 31 is connected to the first connecting part 10 (or the second connecting part 20), or the fixed section 31 is connected to other structures other than the first connecting part 10 and the second connecting part 20. The fixed section 31 is used to provide a fixed foundation for the sealing element 30 and to keep the connecting section 32 and the movable block 33 in their original positions and postures when not subjected to external forces.

[0037] like Figure 5 The two sides of the movable block 33 abut against the first connecting part 10 and the second connecting part 20 respectively. When the first connecting part 10 and the second connecting part 20 move towards each other, the first connecting part 10 and the second connecting part 20 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, such as... Figure 6 The winding sealing block 34 and the first connecting part 10 are in rolling motion, which generates rolling friction. At the same time, the winding 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 winding sealing block 34 to the first connecting part 10 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.

[0038] Furthermore, as the first connecting part 10 and the second connecting part 20 continue to move toward each other, the cross-sectional area of ​​the winding sealing block 34 gradually increases. The two sides of the winding sealing block 34 abut against the first connecting part 10 and the second connecting part 20 respectively. While the distance between the first connecting part 10 and the second connecting part 20 remains unchanged, the compressive force between the winding sealing block 34 and the first connecting part 10 and the compressive force between the winding sealing block 34 and the second connecting part 20 gradually increases. This can provide better sealing for the first connecting part 10 and the second connecting part 20.

[0039] In this embodiment, the fixing segment 31 is fixedly connected to the first connecting part 10, wherein the first connecting part 10 is provided with a mounting groove 11, and the fixing segment 31 is embedded in the mounting groove 11. The fixing segment 31 and the mounting groove 11 are connected by interference fit or adhesive bonding. Therefore, the fixing segment 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.

[0040] Furthermore, the second connecting portion 20 is provided with a receiving cavity 21. When the sealing member 30 has an annular structure, the receiving cavity 21 also has an annular structure. After the first connecting portion 10 passes into the receiving cavity 21, a gap 40 is provided between the first connecting portion 10 and the inner wall of the receiving cavity 21. The movable block 33 and part or all of the connecting section 32 are located within the gap 40. As the movable block 33 rotates and winds the connecting section 32, the connecting section 32 is stretched and deformed. The sealing member 30 is preferably made of rubber or silicone, thereby enabling the winding and stretching of the connecting section 32. In addition, the cross-section of the movable block 33 is circular, which facilitates the rotation of the movable block 33 under the drive of the first connecting portion 10 and the second connecting portion 20 to wind the connecting section 32 connected to the movable block 33.

[0041] Example 2

[0042] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the difference between this embodiment and Embodiment 1 is that the connecting segment 32 has a beginning end 321 and a end end 322. The beginning end 321 of the connecting segment 32 is provided with a movable block 33, and the end end 322 of the connecting segment 32 is connected to the fixed segment 31. The thickness of the connecting segment 32 gradually increases from the beginning end 321 to the end end 322. When the movable block 33 winds around the connecting segment 32, the movable block 33 first winds around the beginning end 321 of the connecting segment 32, and then gradually winds to the middle of the connecting segment 32, and even to the end end 322 of the connecting segment 32. The connecting segment 32 with a lower thickness... The first end 321 is more prone to deformation, which helps the movable block 33 to wind the connecting section 32. As the thickness of the connecting section 32 gradually increases, the cross-sectional area of ​​the winding sealing block 34 formed by the movable block 33 winding the connecting section 32 gradually increases. The resistance fed back from the winding sealing block 34 to the first connecting part 10 and the second connecting part 20 also gradually increases. The installation and maintenance personnel can judge the winding size and winding degree of the winding sealing block 34 by feeling the above resistance, so as to provide a certain force feedback and improve the user experience when installing the first connecting part 10 and the second connecting part 20.

[0043] Example 3

[0044] Combination Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the connecting segment 32 has a first segment block 323 and a second segment block 324 connected to each other. One end of the first segment block 323 is provided with a movable block 33, and the other end of the first segment block 323 is connected to one end of the second segment block 324. The other end of the second segment block 324 is connected to the fixed segment 31. The end of the first segment block 323 with the movable block 33 and the end of the second segment block 324 connected to the fixed segment 31 are arranged opposite to each other. The extension directions of the first segment block 323 and the second segment block 324 are inclined to each other so that the cross-section of the connecting segment 32 is V-shaped. The connecting segment 32 of the seal 30 with this structure can generate a larger deformation, and the cross-sectional area of ​​the wound seal block 34 formed by the movable block 33 winding around the connecting segment 32 can be larger, which can accommodate a larger gap 40 between the first connecting part 10 and the second connecting part 20.

[0045] Example 4

[0046] Combination Figure 5 , Figure 6 and Figure 9As shown, this embodiment provides a display device, including a housing 50, a display module 60, 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 50, and the other is disposed on the display module 60. In other embodiments, the display device further includes a power supply box, and the first connecting part 10 and the second connecting part 20 are respectively disposed on two of the housing 50, the display module 60, and the power supply box.

[0047] In summary, the sealing element 30 is located between the first connecting portion 10 and the second connecting portion 20. The sealing element 30 includes a fixed section 31, a connecting section 32, and a movable block 33 connected in sequence. The two sides of the movable block 33 abut against the first connecting portion 10 and the second connecting portion 20, respectively. When the first connecting portion 10 and the second connecting portion 20 move towards each other, they drive the movable block 33 to rotate and wrap around the connecting section 32 to form a wound sealing block 34. Since the wound sealing block 34 rolls relative to the first connecting portion 10 or the second connecting portion 20, the resistance fed back from the wound sealing block 34 to the first connecting portion 10 and the second connecting portion 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 first connecting portion 10 and the second connecting portion 20, respectively, to provide higher sealing performance.

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.
