The snap-fit ​​hole 111 is used to snap onto a corresponding snap-fit ​​member on one side wall of the TV back panel 200, and the snap-fit ​​member cooperates with the snap-fit ​​hole 111. The first snap-fit ​​groove 112 is used to snap onto a snap-fit ​​plate connected to or integrally formed with the TV back panel 200. In actual use, the TV back panel snap-fit ​​part 110 snaps onto the snap-fit ​​plate along the groove depth direction of the first snap-fit ​​groove 112, and the snap-fit ​​hole 111 cooperates with the snap-fit ​​member to fix the limiting rubber block. The limiting rubber block described in this utility model has the advantage of eliminating the need for processing plastic mid-frames and glass limiting rubber in the production process, simplifying the process, saving expensive molds, materials, and some labor costs, and greatly optimizing time and price costs. For example, if a 55-inch TV uses a plastic mid-frame mold, it requires opening a mid-frame injection mold, resulting in a mold cost of approximately 400,000 yuan and a mold opening time of about 40 days. If the limiting rubber block of this utility model is used, only a silicone extrusion mold is needed, thus requiring only a mold cost of approximately 8,000 yuan and a mold opening time of about 10 days. Data shows that this reduction in time and price costs is significant.

[0028] Preferably, a plurality of snap-fit ​​blocks 113 are provided on one side wall for snapping the TV back panel 200. The snap-fit ​​blocks 113 are disposed outside the snap-fit ​​holes 111.

[0029] In specific implementation, the snap-fit ​​block 113 is used to snap onto the snap-fit ​​hole on one side wall of the TV back panel 200, and the snap-fit ​​block 113 cooperates with the snap-fit ​​hole. The second snap-fit ​​groove 114 is used to snap onto the snap-fit ​​strip on one side wall of the TV back panel 200, and the second snap-fit ​​groove 114 cooperates with the snap-fit ​​strip. In actual use, when the TV back panel snap-fit ​​part 110 moves to the bottom of the groove along the groove depth direction of the first snap-fit ​​groove 112, the snap-fit ​​member snaps onto the snap-fit ​​hole 111, the snap-fit ​​block 113 snaps onto the snap-fit ​​hole, and the second snap-fit ​​groove 114 snaps onto the snap-fit ​​strip. This design allows the limiting rubber block to be more tightly snapped onto the TV back panel 200.

[0030] Preferably, the number of the second snap-fit ​​slots 114 is 2 or 4 and they are arranged symmetrically.

[0031] In practice, the above design allows the limiting rubber block to be snapped onto the TV back panel 200 in a symmetrical snap-fit ​​manner, thereby making the connection between the limiting rubber block and the TV back panel 200 tighter.

[0032] Preferably, the snap-fit ​​block 113 is rounded rectangle or circle, and the side wall of the snap-fit ​​block 113 is provided with an installation groove on the limiting rubber block. The snap-fit ​​block 113 is installed in the installation groove or directly disposed on the side wall of the TV back panel 200.

[0033] In specific implementation, the mounting groove is combined with the snap-fit ​​block 113 located therein, and the snap-fit ​​component of the corresponding shape on the TV back panel 200 is snapped together. The purpose of setting the mounting groove is to make the connection between the limiting rubber block and the TV back panel 200 tighter by cooperating with the corresponding block part on the snap-fit ​​component.

[0034] Preferably, the snap-fit ​​hole 111 is a blind hole, and there are two of them.

[0035] Preferably, the snap-fit ​​hole 111 is a through hole, and the number of them is one.

[0036] Preferably, the rear side of the limiting part is provided with a stepped surface 122 of the limiting part that is higher than the supporting surface 121 of the limiting part.

[0037] In practice, the above design makes demolding easier.

[0038] Preferably, the length of the limiting rubber block is 20-35mm, the width is 8-20mm, and the thickness is 6-12mm.

[0039] In practice, within the aforementioned size range, the dimensions of other structures shall adopt those of existing technologies. Those skilled in the art can select the dimensions of existing technologies according to actual needs.

[0040] Preferably, the limiting rubber block is made of silicone.

[0041] In practice, the limiting blocks are made of silicone, which not only fulfills the required functions of the limiting blocks, but also reduces processing costs, processing time, and makes processing more convenient and simple.

[0042] This utility model also provides a frameless television set, characterized in that it includes the limiting rubber block described in any of the above technical solutions.

[0043] In actual installation and use, the frameless TV has corresponding components for snapping on the iron back plate. In actual use, when the snapping part 110 of the TV back plate moves to the bottom of the groove along the groove depth direction of the first snapping groove 112, the snapping part snaps on the snapping hole 111.
