Description

Technical Field

[0001] This utility model relates to the field of sealing rings and displays, and in particular to a waterproof rubber ring and an outdoor display. Background Technology

[0002] Sealing rings are components used to seal the interior of a product from the outside. In the current technology, outdoor displays face multiple challenges such as rain impact, temperature difference deformation, and dust intrusion. Existing rubber rings, due to their simple structure, such as simple O-rings or rectangular cross-sections, cannot effectively cope with the dynamic displacement between the housing and the screen, and are prone to local gaps. At the same time, they require high installation accuracy. If there is a slight misalignment between the housing and the display frame or uneven assembly pressure, the rubber ring may deform due to local excessive compression, reducing the reliability of the seal and thus affecting the sealing effect. Utility Model Content

[0003] Therefore, it is necessary to provide a waterproof rubber ring and an outdoor display screen to address the problems in the existing technology.

[0004] A waterproof rubber ring, characterized in that it includes an annular body, and at least three raised sealing portions are provided on the inner and outer sides of the annular body.

A connecting rib is provided in the trapezoidal groove that is not higher than the outer side of the sealing portion, and the connecting rib is distributed at intervals along the direction of the annular body.

[0005] In one embodiment, the connecting ribs in adjacent trapezoidal grooves are staggered.

[0006] In one embodiment, the sealing ring has a sealing gasket on its side, the width of which is greater than the width of the annular body and the sealing part, and the sealing gasket has fixing holes that are staggered on both sides of the annular body.

[0007] In one embodiment, the thickness of the sealing gasket is 2-6 mm.

[0008] The aforementioned waterproof rubber ring has added connecting ribs between the raised sealing parts. This prevents the sealing parts from deforming during the use of the waterproof rubber ring, resulting in a better sealing effect over a long period of use.

[0009] An outdoor display screen is characterized in that it includes a housing and a cover, the housing having an annular groove for accommodating a waterproof rubber ring, and the waterproof rubber ring being pressed between the cover and the housing when the cover is closed.

[0010] In one embodiment, the bottom of the annular groove is provided with a plurality of protrusions, the cross-section of which is an arc surface or a triangle and is distributed along the direction of the annular groove. The contact surface between the cover and the waterproof rubber ring is provided with a textured part.

[0011] In one embodiment, the cover has a groove corresponding to the waterproof rubber ring sealing gasket, the height of which is less than the thickness of the sealing gasket.

[0012] In one embodiment, the housing or cover is provided with a threaded hole corresponding to the fixing hole of the waterproof rubber ring gasket, and a screw passing through the fixing hole is provided at the location of the threaded hole for fixing the cover and the housing together.

[0013] In one embodiment, the housing is provided with heat dissipation holes, and a waterproof and breathable membrane is provided at the location of the heat dissipation holes.

[0014] In one embodiment, the mating surface of the housing and the cover is provided with a wire inlet hole, the wire inlet hole is provided with a snap-fit ​​groove, a cable is provided at the wire inlet hole, and a waterproof plug is provided on the outside of the cable to snap-fit ​​and seal with the snap-fit ​​groove. The waterproof plug is snapped into the snap-fit ​​groove by interference fit.

[0015] The aforementioned outdoor display screen uses a waterproof rubber ring as a sealing structure, which is set between the shell and the cover. After the shell and the cover are fixed, the waterproof rubber ring forms a multi-layer seal, thereby improving the waterproof effect of the outdoor display screen and thus extending its service life.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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.

[0024] like Figures 1 to 4 As shown, a waterproof rubber ring is characterized by comprising an annular body 1, wherein at least three sealing portions 2 with protrusions 52 are provided on both the inner and outer sides of the annular body 1, the sealing portions 2 having a trapezoidal cross section, and a trapezoidal groove 62 being formed between adjacent sealing portions 2, wherein a connecting rib 3 not higher than the outer side of the sealing portion 2 is provided in the trapezoidal groove 62, and the connecting rib 3 is distributed at intervals along the direction of the annular body 1.

[0025] By adding connecting ribs 3 between the sealing portions 2 of the protrusions 52, the sealing portions 2 are less prone to deformation during the use of the waterproof rubber ring, resulting in better sealing performance over long-term use.

[0026] At this time, adjacent sealing parts 2 are connected together by connecting ribs 3. Meanwhile, to avoid affecting the sealing effect formed by the deformation of the sealing parts 2 upon contact with the outside, in this embodiment, the connecting ribs 3 in adjacent trapezoidal grooves 62 are staggered. Thus, with the connecting ribs 3 staggered, when the waterproof rubber ring is engaged in the annular groove 51, the sealing part 2 is less affected by the connecting ribs 3 during deformation, preventing the waterproof rubber ring from being difficult to assemble into the annular groove 51. Furthermore, when the sealing part 2 deforms due to usage time or external force, the connecting ribs 3 ensure that the sealing part 2 of the protrusion 52 forms a whole, minimizing deformation and thus guaranteeing the sealing effect.

[0027] Meanwhile, to better secure the waterproof rubber ring and achieve a better seal, in this embodiment, a sealing gasket 4 is provided on the side of the sealing ring. The width of the sealing gasket 4 is greater than the width of the annular body 1 and the sealing part 2. The sealing gasket 4 has fixing holes 41, which are staggered on both sides of the annular body 1. After the fixing holes 41 are provided, the screws that fix the housing 5 and the cover 6 pass through the fixing holes 41, so that the waterproof rubber ring will not move between the housing 5 and the cover 6, thereby ensuring the sealing effect.

[0028] Furthermore, the thickness of the sealing gasket 4 is 2-6mm. By setting a certain thickness for the sealing gasket 4, this portion of the sealing gasket 4 is sandwiched between the housing 5 and the cover 6. This way, after the cover 6 and the housing 5 are fixed, another layer of seal can be formed at the contact surface. Specifically, in this embodiment, the thickness of the sealing gasket 4 is 3mm.

[0029] In another embodiment, an outdoor display screen is provided, including a housing 5 and a cover 6. The housing 5 has an annular groove 51 for accommodating a waterproof rubber ring. When the cover 6 is closed with the housing 5, the waterproof rubber ring is pressed between the cover 6 and the housing 5. Using the waterproof rubber ring as a sealing structure in the above embodiment, and placing it between the housing 5 and the cover 6, after the housing 5 and the cover 6 are fixed, a multi-layer seal is formed by the waterproof rubber ring, thereby improving the waterproof effect of the outdoor display screen and thus extending its service life.

[0030] At this point, to increase the tightness of the contact surface between the waterproof rubber ring and the cover 6 and the housing 5, the bottom of the annular groove 51 is provided with several protrusions 52. The cross-section of the protrusions 52 is an arc surface or a triangle, and they are distributed along the direction of the annular groove 51. The contact surface between the cover 6 and the waterproof rubber ring is provided with a textured part 61. By providing the protrusions 52 at the bottom of the annular groove 51 and the textured part 61 at the contact surface between the cover 6 and the waterproof rubber ring, the contact surface between the housing 5 and the cover 6 is more firmly pressed when the housing 5 and the cover 6 are fixed. At the same time, the protrusions 52 distributed along the annular groove and the textured part 61 can divide the waterproof rubber ring into multiple independent spaces at the bottom and positioning. If water seepage occurs at the top or bottom of the waterproof rubber ring, the water flow rate can be reduced, thereby improving the waterproof effect.

[0031] By setting the protrusions 52 and the textured parts 61, the pressure of the cover 6 and the shell 5 on the waterproof rubber ring can be made more uniform, so as not to cause uneven deformation of the waterproof rubber ring, thereby improving the sealing effect.

[0032] Meanwhile, since the waterproof rubber ring is equipped with a sealing gasket 4, in this embodiment, the cover 6 is provided with a groove 62 corresponding to the waterproof rubber ring sealing gasket 4, and the height of the groove 62 is less than the thickness of the sealing gasket 4. At this time, the cover 6 is provided with a corresponding groove 62, the width of which is slightly greater than the width of the sealing gasket 4. This ensures that the upper side of the sealing gasket 4 is pressed tightly against the cover 6, and the lower side of the sealing gasket 4 is pressed tightly against the housing 5 through the cover, thereby further improving the sealing effect.

[0033] Of course, at this time, in order to further improve the sealing effect, an annular body 1 and a sealing part 2 are also provided on the upper side of the sealing gasket 4. In this way, the cross-section of the sealing gasket 4 can be a symmetrical structure, so as to improve the sealing effect between the upper part of the sealing gasket 4 and the shell 5.

[0034] Meanwhile, in order to fix the waterproof rubber ring to the housing 5 and the cover 6, and to form a better seal between the housing 5 and the cover 6, in this embodiment, the housing 5 or the cover 6 is provided with a threaded hole corresponding to the fixing hole 41 of the waterproof rubber ring sealing gasket 4. The threaded hole is provided with a screw that passes through the fixing hole 41 to fix the cover 6 and the housing 5 together.

[0035] Since this is for outdoor display screens, some heat dissipation is required to avoid affecting the normal use of the display screen. Therefore, in this embodiment, the housing 5 is provided with heat dissipation holes, and a waterproof and breathable membrane is provided at the location of the heat dissipation holes. The waterproof and breathable membrane is made of PTEF membrane, which has the effect of being breathable and water-resistant. Thus, while being waterproof, it does not affect the flow of air, thereby ensuring heat dissipation.

[0036] Finally, the mating surfaces of the housing 5 and the cover 6 are provided with a cable inlet hole. A snap-fit ​​groove is provided at the cable inlet hole location, and a cable is positioned there. A waterproof plug is provided on the outside of the cable, which engages and seals with the snap-fit ​​groove. The waterproof plug is secured in the snap-fit ​​groove via an interference fit. By positioning the cable inlet hole at the contact surface between the housing 5 and the cover 6, water leakage is prevented from occurring at the cable inlet hole location after the cable is secured with the waterproof plug.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
