The middle frame body 110 is used to support a screen, and includes a supporting surface 1101 to support the screen and a plurality of side surfaces 1102 connected to the supporting surface 1101. When the screen is installed using the middle frame 100, the screen is placed and fixed on the supporting surface 1101 of the middle frame main body 110.
The adhesive member 120 is used for adhering the screen and the middle frame body 110, and the adhesive member 120 includes a main body portion 121 disposed on the supporting surface 1101 and at least one extending portion 122 disposed on at least one side 1102 and connected to the main body portion 121. The main body 121 provided on the supporting surface 1101 fixes the screen on the supporting surface 1101 of the center frame body 110, and the extension 122 provided on the side surface 1102 is connected to the main body 121, so that the tangential force of the main body 121 can be increased. Wherein the number of the extensions 122 may be one, two, or more.
When the screen is supported by the frame 100 in use in the prior art, the adhesive piece 120 only comprises the main body part 121 arranged on the supporting surface 1101, compared with the prior art, the adhesive piece 120 has the advantages that the extension part 122 connected with the main body part 121 is increased, the tangential force of the main body part 121 can be increased, the probability of separation of the adhesive piece 120 and the middle frame main body 110 is reduced, the fixed connectivity of the screen and the middle frame 100 is ensured, and when the screen falls, the screen is not easily separated from the middle frame 100.
With reference to fig. 3, the middle frame body 110 includes an outer frame 111 and an inner frame 112 connected to an inner sidewall 1111 of the outer frame 111.
The frame surface 1121 of the inner frame 112 is a support surface 1101 on which the middle frame body 110 supports the screen, and the side walls 1122 on which the inner frame body 112 is not connected to the outer frame body 111 are the side surfaces 1102 of the middle frame body 110. In the present embodiment, the outer frame 111 and the inner frame 112 are both rectangular frames. When the screen is fixed to the frame surface 1121 of the inner frame 112, the inner side wall 1111 of the outer frame 111 surrounds the periphery of the screen. Alternatively, in another embodiment, the inner side wall 1111 of the outer frame 111 may also be a plurality of side surfaces 1102 of the middle frame main body 110, specifically, in contrast to fig. 2, at this time, the extending portion 122 is not bent downward from the main body portion 121, but is bent upward from the main body portion 121.
In order to avoid the space occupied by the extension portions 122 disposed on the side surfaces 1102, at least one groove 1123 is disposed on the side wall 1122 where the inner frame 112 is not connected to the outer frame 111, the number of the grooves 1123 is the same as the number of the extension portions 122, and different extension portions 122 are disposed in different grooves 1123, that is, one groove 1123 is disposed with one extension portion 122. Optionally, the thickness of the extension 122 is equal to the depth of the groove 1123. Optionally, the extension 122 is rectangular, and the height of the extension 122 is the same as the height of the side 1102. When the extension portion 122 is plural, the plural extension portions 122 may be the same or different in shape.
The frame surface 1121 of the inner frame 112 includes a first region 11211 and a second region 11212, and the area of the first region 11211 is smaller than the area of the second region 11212.

In general, the smaller the bonding surface of the adhesive member 120, the easier it is to separate from the bonding surface, and for example, the probability that the first body 1211 separates from the first region 11211 is greater for the first region 11211 and the second region 11212 than for the second body 1212 and the second region 11212. Thus, in the present application, providing at least one extension portion 122 in connection with the first body portion 1211 covering the first region 11211 increases the tangential force of the first body portion 1211, reducing the probability that the first body portion 1211 will separate from the first region 11211. In the present application, the number of the first regions 11211 and the number of the second regions 11212 are both two and are both rectangular, the two first regions 11211 are disposed oppositely, the two second regions 11212 are disposed oppositely, the first regions 11211 correspond to the long side of the screen, and the second regions 11212 correspond to the short side of the screen. When the plurality of extending portions 122 are connected to the first main body portions 1211 at the same time, the plurality of extending portions 122 are disposed at equal intervals, and for two first main body portions 1211, the same number of extending portions 122 are connected thereto.
Optionally, in other embodiments, in order to increase the tangential force of the second main body portion 1212, a plurality of extension portions 122 are also provided to connect with the second main body portion 1212.
In order to reduce the usage of the mold in the processing process and reduce the production cost, the bonding member 120 is integrally formed, that is, the bonding member 120 is formed by using the mold at one time. Of course, in other embodiments, the adhesive member 120 may not be integrally molded, and when the adhesive member 120 is not integrally molded, the edge of the extension portion 122 of the adhesive member 120 may overlap the edge of the main body portion 121, that is, the extension portion 122 overlaps the main body portion 121.
The adhesive member 120 is a double-sided tape, and it should be noted that, when the middle frame 100 in the present application does not support the screen, a surface of the adhesive member 120 not in contact with the supporting surface 1101 of the middle frame main body 110 is covered with a release paper, and the release paper is not removed until the screen is fixed.
