DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: in the anti-electromagnetic interference of liquid crystal screens, the transmission line of the liquid crystal screen is mainly protected. At present, the protection measures are mainly to shorten the transmission line and wrap the line with an anti-interference layer. However, no matter what construction method is used, the building where the line is located needs to be demolished. This is not only time-consuming and labor-intensive, but also has mixed effects. The application discloses an anti-electromagnetic interference device for liquid crystal screens, which adopts a wrapping quick-installation design, mainly for the data transmission line of the liquid crystal screen to perform anti-interference protection, and avoid electromagnetic interference of the same pipe line to the data transmission line. The main body is divided into a pipe clamp 1 and a clamp 2 and an anti-interference protective structure connected to the clamp 2, wherein the pipe clamp 1 is an annular structure, and a plurality of outer ring clamps 3 are arranged on the pipe clamp 1. The pipe clamp 1 is clamped on the pipe mouth of the line pipe through the outer ring clamp 3. The pipe clamp 1 is connected to the clamp 2, and the clamp 2 is used to be fixed on the data transmission line. The pipe clamp 1 can be removed from the clamp 2 to wrap and protect the liquid crystal screen transmission line with the outer transmission structure of the pipe.

[0021] According to the instruction manual Figure 1-3 It can be known that the above-mentioned clamp 2 is connected with a protective ring sleeve 4, which is a semi-circular tubular structure. One side of the notch of the protective ring sleeve 4 extends a plurality of pairs of arc-missing blocks 5 in a unidirectional linear array. The plurality of pairs of arc-missing blocks 5 are symmetrically arranged on both sides of the protective ring sleeve 4, and an arc-missing groove of not less than 15° is provided between the opposite pairs of arc-missing blocks 5. In the specific implementation process, when clamping, the arc-missing groove between the arc-missing blocks 5 of the protective ring sleeve 4 is aligned with the line and pressed in forcefully, so that the head end of the protective ring sleeve 4 is clamped on the data transmission line to be protected, and then the protective ring sleeve 4 is pushed along the axial direction of the data transmission line, and the arc-missing blocks 5 on the protective ring sleeve 4 are all stuck on the outside of the data transmission line, so that the protective ring sleeve 4 is completely wrapped;

[0022] According to the instruction manual Figure 1-3 It can be seen that an arc-missing tube groove 6 is protrudingly provided on the semicircular inner wall of the protective ring sleeve 4, the arc-missing tube groove 6 is coaxially arranged with the protective ring sleeve 4, the inner layer of the arc-missing tube groove 6 is provided with a first anti-interference layer, and a semicircular annular rotating groove 7 is opened in the axial direction of the upper arc-missing tube groove 6, and the first anti-interference layer of the inner layer of the arc-missing tube groove 6 is used to perform anti-interference protection on the internal data transmission cable;

[0023] According to the instruction manual Figure 1-3 It can be known that a missing arc rotating protective sleeve 8 is installed in the semicircular ring rotating groove 7. The missing arc rotating protective sleeve 8 is an annular body with a missing arc of at least 150°. The inner wall of the missing arc rotating protective sleeve 8 is provided with a second anti-interference layer. When the protective ring sleeve 4 completely wraps the outside of the data transmission line to be protected, the missing arc rotating protective sleeve 8 is rotated to rotate to the other side of the corresponding missing arc tube groove 6, so that the second anti-interference layer is used to comprehensively wrap and protect the data transmission line.

[0024] As a preferred solution, further, the protective ring sleeve 4 is a tubular body made of soft rubber material, which is easy to install and use.

[0025] As a preferred embodiment, further, the clamp 2 includes a skin cover 21, which is a partially conical structure. The large diameter side of the skin cover 21 is connected to the annular edge of the pipe clamp 1, and the small diameter side of the skin cover 21 is provided with a strapping belt 22. By pulling the strapping belt 22, the pipe mouth of the skin cover 21 is tightened and closed, so that the head end of the skin cover 21 is fixed to the liquid crystal data transmission line. Due to the action of the strapping belt 22, the protective ring sleeve 4 connected to the pipe mouth of the skin cover 21 is locked and fixed to the data transmission line, so as to prevent the protective ring sleeve 4 from leaving the effective protection range due to gravity.

[0026] As a preferred solution, further, the first anti-interference layer and the second anti-interference layer are all silver fiber fabric layers, which have good anti-interference properties.

[0027] As a preferred solution, further, a pair of limiting grooves 9 are opened on the top of the semicircular ring groove 7, and a limiting block 10 is set on the top of the corresponding missing arc rotating protective sleeve 8 to limit the position of the missing arc rotating protective sleeve 8 to avoid rolling.

[0028] As a preferred solution, further, a toggle block 11 is provided on one side of the top midpoint of the missing arc rotating protective sleeve 8 to facilitate the rotation of the missing arc rotating protective sleeve 8.

[0029] From the above, it can be generally known that the anti-electromagnetic interference device for the LCD screen, for the data transmission line of the LCD screen that is easily interfered with, wraps the protective ring sleeve 4 with a missing arc structure on the outside of the line, and at the same time uses the missing arc tube groove 6 that can be rotated and buckled to form a tubular structure in the protective ring sleeve 4 and the missing arc rotating protective sleeve 8 to omnidirectionally wrap the data transmission line to prevent the data transmission line from external electromagnetic interference. At the same time, the method of plugging along the data transmission line is adopted, which is simple to operate and has a good protection effect.
