Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a sealing ring assembly structure and an electronic device.

Background Art

[0002] In the prior art, an assembly hole is provided on an assembly body. In order to prevent external dust and foreign matters from invading the assembly hole, a sealing ring coaxially arranged with the assembly hole needs to be adhered to the surface of the assembly body to protect the assembly hole. However, the existing sealing rings are directly adhered to the planar surface of the assembly body. During assembly, it is difficult to accurately paste the sealing ring onto the assembly body and it is very easy to paste it obliquely, which not only affects the sealing effect but also may block the assembly hole, seriously affecting the product yield.

[0003] Therefore, it is necessary to provide a sealing ring assembly structure and an electronic device that are easy to assemble.

Specific Embodiment

[0031] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] An embodiment of the present utility model provides a seal ring assembly structure 10, including an assembly body 1 and a seal ring 2. Please refer to Figures 1 to 9 as shown. The assembly body 1 includes a main body 101 and a limiting convex ring 102, and the limiting convex ring 102 protrudes from the main body 101. The limiting convex ring 102 and the main body 101 jointly enclose a limiting groove 103, and a first through hole 104 is opened on the main body 101, and the first through hole 104 communicates with the limiting groove 103. The seal ring 2 is received in the limiting groove 103. The seal ring 2 includes a ring body 201 and an adhesive layer 202, and the adhesive layer 202 is fixed to the bottom surface of the ring body 201. The ring body 201 is adhesively fixed to the bottom surface 1031 of the limiting groove 103 through the adhesive layer 202. When the ring body 201 is fixed in the limiting groove 103, the side surface 2011 of the ring body 201 abuts against the groove wall of the limiting groove 103. The seal ring 2 further includes a second through hole 203, and the second through hole 203 penetrates through the ring body 201 and the adhesive layer 202, and the second through hole 203 is coaxially arranged with the first through hole 104.

[0033] In the embodiment of the present utility model, the limiting convex ring 102 and the main body 101 of the assembly 1 jointly enclose a limiting groove 103. The ring body 201 of the sealing ring 2 is adhesively fixed to the bottom surface 1031 of the limiting groove 103 through the adhesive layer 202, and the side surface 2011 of the ring body 201 abuts against the groove wall of the limiting groove 103, so that the second through hole 203 and the first through hole 104 can be effectively aligned to achieve coaxial setting. It can effectively avoid poor sealing effect or even inability to seal caused by the sealing ring 2 being pasted obliquely, and can also effectively avoid the assembly 1 being unable to be effectively assembled with other environmental components due to the sealing ring 2 blocking the first through hole 104. It is not only easy to assemble, but also accurately assembled, improving the sealing effect, assembly efficiency and product yield.

[0034] In some preferred embodiments, along the direction from the notch to the bottom of the limiting groove 103, the limiting groove 103 successively includes a first groove section 1032 and a second groove section 1033. Please refer to Figure 4 and Figure 6 as shown. The groove wall of the first groove section 1032 is a conical surface. And, along the direction from the notch to the bottom of the limiting groove 103, the diameter of the first groove section 1032 gradually decreases, so as to facilitate the installation of the sealing ring 2 into the limiting groove 103. The groove wall of the second groove section 1033 is a cylindrical surface. The side surface 2011 of the ring body 201 is a cylindrical surface, and the side surface 2011 of the ring body 201 abuts against the groove wall of the second groove section 1033, so as to ensure the sealing effect.

[0035] In some preferred embodiments, please refer to Figure 8 and Figure 9 as shown. The hole wall of the second through hole 203 is a cylindrical surface. Please refer to Figure 7 , along the direction away from the limiting groove 103, the first through hole 104 successively includes a first hole section 1041 and a second hole section 1042. The hole wall of the first hole section 1041 is a cylindrical surface, and the diameter of the first hole section 1041 is equal to the diameter of the second through hole 203, so as to further improve the sealing effect and not interfere with the assembly of the assembly 1 with other environmental components through the first through hole 104. The hole wall of the second hole section 1042 is a conical surface, and along the direction away from the limiting groove 103, the diameter of the second hole section 1042 gradually increases, so as to facilitate the assembly of the assembly 1 with other environmental components through the first through hole 104.

[0036] In some preferred embodiments, please refer to Figure 2 and Figure 7 as shown. When the ring body 201 is fixed in the limiting groove 103, the top surface 2012 of the ring body 201 is exposed from the limiting groove 103, that is to say, the height of the sealing ring 2 is greater than the depth of the limiting groove 103, so as to facilitate the assembly operation and can fix the sealing ring 2 in the limiting groove 103 more firmly.

[0037] In some preferred embodiments, the ring body 201 can be made of silica gel, which is not only easy to assemble, but also has good sealing effect and long service life. It should be noted that in other embodiments, the ring body 201 can also be made of other materials, which will not be elaborated here.

[0038] In some preferred embodiments, please refer to Figure 7 As shown, the ring body 201 includes a first rounded corner surface 2013 extending between the side surface 2011 of the ring body 201 and the bottom surface of the ring body 201. The ring body 201 having the first rounded corner surface 2013 makes it easier to install the sealing ring 2 into the limiting groove 103, improving the assembly efficiency.

[0039] Correspondingly, please refer to Figure 4 and Figure 7 As shown, a second rounded corner surface 1034 is formed on the assembly body 1 and extends between the groove wall of the limiting groove 103 and the groove bottom surface 1031 of the limiting groove 103. The second rounded corner surface 1034 abuts against the first rounded corner surface 2013, which can make the sealing ring 2 fit more closely with the limiting groove 103, improving the sealing effect.

[0040] In some preferred embodiments, the adhesive layer 202 is a double-sided adhesive, which not only has low cost, is convenient to use and easy to assemble, but also can effectively fix the ring body 201 on the assembly body 1. It should be noted that in other embodiments, the adhesive layer 202 can also be other adhesives, which will not be elaborated here.

[0041] In some preferred embodiments, please refer to Figure 1 、 Figure 3 and Figure 5 As shown, the assembly body 1 includes a plurality of limiting convex rings 102. Each limiting convex ring 102 and the main body 101 jointly enclose a limiting groove 103 respectively. That is to say, the number of the limiting grooves 103 is equal to the number of the limiting convex rings 102. A plurality of first through holes 104 are formed on the main body 101, and the first through holes 104 are arranged in one-to-one correspondence with the limiting grooves 103. The sealing ring assembly structure 10 includes a plurality of sealing rings 2, and the sealing rings 2 are arranged in one-to-one correspondence with the limiting grooves 103. Each sealing ring 2 is installed in the corresponding limiting groove 103. As an example, when installing the sealing ring 2 during assembly, an automated device can be used for automated assembly, and multiple sealing rings 2 can be assembled at one time, thereby improving the production efficiency.

[0042] The embodiment of the present invention also provides an electronic device, including the sealing ring assembly structure 10 of any one of the above.

[0043] The above are only the embodiments of the present utility model. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present utility model, but these all fall within the protection scope of the present utility model.
