Description

Technical Field

[0001] The utility model belongs to the technical field of resistor film production, and in particular relates to a matte anti-coil resistor film. Background Art

[0002] ITO transparent resistor film is suitable for resistive touch products. According to the different types of substrates, it is divided into single-sided bright resistor film, bright anti-coil resistor film, bright anti-scratch resistor film and matte anti-coil resistor film. Different types of film materials have different display effects. The application terminals cover from small to large sizes and are mainly used on LCD touch screens.

[0003] Among them, matte anti-Newton ring resistor film is a commonly used film. After production, the resistor film will be wrapped around the surface of the core tube for easy use. However, if the core tube is flush with the end face of the resistor film, although it is convenient for vertical placement, the resistor film needs to be placed horizontally on the roller when used. The flush end face is often damaged by collision due to improper operation during installation and use. On the contrary, if the end of the core tube exceeds the resistor film, it cannot be placed vertically, resulting in difficulties in transportation and storage. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a matte anti-cow resistor film, which can be achieved by providing a slidable sleeve at the end of the core tube. When vertically prevented, the bottom sleeve can be slid into the inside of the core tube to keep the bottom end surface flush. Conversely, when in use, the sleeves on both sides are slid out to protect it.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A matte anti-coil resistor film comprises a resistor film and a core tube. The resistor film is stacked and wound on the surface of the core tube. The resistor film and the core tube have the same width. The resistor film is sequentially stacked with a PET protective film, an ITO film, a silver nanofilm layer, an ITO film, and a PET protective film. The core tube is hollow inside, and both ends of the core tube are concentrically slid with sliding sleeves.

[0007] Furthermore, the inner walls at both ends of the core barrel are symmetrically provided with docking grooves, and convex strips are arranged on both sides of the surface of the sliding sleeve, and the convex strips slide inside the docking grooves.

[0008] Furthermore, a card slot A is provided at the front side of the docking slot, and a card slot B is provided at the rear side of the docking slot, and the card slot A and the card slot B have the same size.

[0009] Furthermore, a mounting hole is provided at one end of the surface of the convex strip, and a movable clamp is slidably penetrated through the inner side of the mounting hole, and the movable clamp is adapted to the inside of the clamping slot A.

[0010] Furthermore, the movable clamp is a trapezoidal structure, a spring is arranged inside the mounting hole, and the spring is in contact with the end surface of the movable clamp.

[0011] Furthermore, the thickness of the silver nanofilm layer is 30-60 nanometers.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the matte anti-cow resistor film is wound on the surface of a core tube of equal width to make the resistor film flush with the end face of the core tube, which is convenient for stability during vertical placement; when horizontal placement is required, the sleeve can be slid out beyond the end face of the core tube, and the sleeve and the core tube are fixed by the structure, so that the resistor film maintains a certain spacing distance between the devices on both sides when in use, thereby protecting the resistor film.

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1-Figure 4As shown, a matte anti-coil resistor film comprises a resistor film 1 and a core tube 2. The resistor film 1 is stacked and wound on the surface of the core tube 2 to facilitate installation, transportation and use. The resistor film 1 and the core tube 2 have the same width so that the end faces are flush. The resistor film 1 is sequentially stacked with a PET protective film 101, an ITO film 102, and a silver nanofilm layer 103 to control resistance. The ITO film 102 and the PET protective film 101 protect both sides of the conductive film. The core tube 2 is hollow inside. Both ends of the core tube 2 are concentrically slid with sliding sleeves 4 to control whether the sliding sleeves 4 slide out to switch whether the end faces are in a flush state.

[0021] Please refer to Figure 2 and Figure 3 As shown, the inner walls at both ends of the core barrel 2 are symmetrically provided with docking grooves 3, and convex strips 5 are arranged on both sides of the surface of the sliding sleeve 4. The convex strips 5 slide on the inner side of the docking groove 3, and the sliding sleeve 4 can only slide axially through the cooperation of the convex strips 5 and the docking groove 3. A card slot A31 is opened on the front side of the docking groove 3, and a card slot B32 is opened on the rear side of the docking groove 3. The card slots A31 and B32 have the same size, and a mounting hole 6 is opened on one end of the surface of the convex strip 5. A movable clamp 7 slides through the inner side of the mounting hole 6. The movable clamp 7 is adapted to the inside of the clamp A31, and the movable clamp 7 cooperates with the clamp A31 or the clamp B32 to keep the sliding sleeve 4 fixed in an extended or retracted state.

[0022] Among them, the movable clamp head 7 is a trapezoidal structure. The trapezoidal structure allows the sliding sleeve 4 to be driven to move again by pushing inward or pulling outward with force after the sliding sleeve 4 is fixed. A spring 8 is arranged inside the mounting hole 6. The spring 8 contacts the end surface of the movable clamp head 7. The elastic force of the spring 8 allows the end of the movable clamp head 7 to enter the slot A31 or the slot B32 after the sliding sleeve 4 slides in or out of place, thereby achieving fixation.

[0023] Please refer to Figure 4 As shown, the thickness of the silver nanofilm layer 103 is 30-60 nanometers, which can achieve effective control of conductivity and resistance.

[0024] The working principle of the utility model is as follows: the resistance film 1 is wound on the surface of the core tube 2. Due to the existence of the spring 8, the movable clamp 7 always has an outward thrust. When vertically prevented, the sliding sleeve 4 can be allowed to enter the core tube 2 by gravity. At this time, the movable clamp 7 cooperates with the rear side clamping groove B32 to make the sliding sleeve 4 completely lock the inside of the core tube 2, so that the bottom of the core tube 2 is flush, which is convenient for vertical placement. Conversely, when in use, it can be used to pull the sliding sleeve 4, and the inclined surface of the trapezoidal structure movable clamp 7 is used to make the movable clamp 7 lock the inside of the mounting hole 6, so that the sliding sleeve 4 protrudes beyond the end surface of the core tube 2, so that the movable clamp 7 cooperates with the front side clamping groove A31 to preliminarily fix the sliding sleeve 4, and keep the sliding sleeve 4 protruding, so as to protect the internal resistance film 1 when discharging the material, and form an isolation distance.

[0025] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented by conventional means in the art without special instructions and limitations.
