Description

Technical Field

[0001] The utility model relates to a roller reinforcement support structure and belongs to the technical field of sliding screen testing equipment. Background Art

[0002] Flexible materials have excellent performance and can be flipped and folded to reduce product area. They have been widely used in electronic products, such as flexible screens for mobile phones and TVs. However, electronic products have a long service life and high quality requirements, and they have high requirements for the flexibility and service life of flexible materials. Therefore, in the processing and production of flexible materials, it is usually necessary to test the curling and stretching ability of flexible materials under a given tensile force.

[0003] At present, the traditional way to test the rolling screen is to stick the screen to the fixture platform at both ends with easy-to-pull adhesive, and then set a single roller and bearing on the support base to form a rolling mechanism (such as Figure 1 As shown in the figure, this rolling mechanism is used to repeatedly test the screen. When this type of rolling mechanism needs to test a smaller rolling diameter or a wider sliding screen sample, a single roller cannot withstand the external force generated by the test and is more likely to bend and deform, which greatly reduces the straightness of the roller, resulting in inaccurate test results. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a roller reinforcement support structure.

[0005] The technical solution of the utility model is as follows:

[0006] A roller reinforcement support structure includes a support base and a roller body, wherein a support plate is arranged on the support base, a first mounting groove is opened inwardly on one side wall of the support plate, the roller body is rotatably connected in the first mounting groove, a plurality of second mounting grooves are also opened on the first mounting groove, and the spacing between adjacent second mounting grooves is arranged in the same manner, a plurality of rollers are sleeved on the roller body, the rollers are arranged in the second mounting grooves, and the top cylinder wall of the rollers is arranged higher than the top wall of the support plate.

[0007] Wherein, the number of rollers arranged in each of the second installation grooves is the same.

[0008] Wherein, the second installation grooves are distributed symmetrically within the first installation groove.

[0009] Wherein, the rollers are distributed in the second installation groove in a symmetrical arrangement.

[0010] Wherein, the support plate is made of elastic material, the first mounting groove is arranged in an arc-shaped structure, and the first mounting groove is embraced and connected with the roller body.

[0011] Wherein, the roller is made of PEEK material.

[0012] Wherein, limiting screws are arranged on both side walls of the support plate, and the nut portion of the limiting screw is arranged to abut against the end of the corresponding side roller body.

[0013] Wherein, threaded holes are provided on both side walls of the support plate, and the limiting screws on both sides are arranged on the support plate by being threadedly connected with the corresponding side threaded holes.

[0014] The utility model has the following beneficial effects:

[0015] The utility model arranges a support plate on a support base, installs the roller body by using the support plate, and at the same time, sleeves a plurality of rollers on the roller body, and the plurality of rollers cooperate with each other to test the rolling screen. Currently, the roller bodies of the support structure with diameters of 3mm and 3.5mm have been tested. When testing the rolling screen, they can bear a force of about 50N and are not easy to deform. However, the rolling mechanism of a single roller commonly used in the prior art will undergo more serious deformation when tested on the basis of the same length and diameter. Therefore, compared with the rolling mechanism of a traditional single roller, the utility model has the advantages of being stronger and less prone to deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example: Please refer to Figures 2 to 4The present embodiment provides a roller reinforcement support structure, including a support base 1 and a roller body 2. A support plate 3 is fixedly arranged on the top surface of the support base 1. A first mounting groove 4 is provided inwardly on the front side wall of the support plate 3. The roller body 2 is rotatably connected in the first mounting groove 4. A plurality of second mounting grooves 5 are also provided on the first mounting groove 4. Each second mounting groove 5 is provided to pass through the upper and lower side walls of the first mounting groove 4. The specific number of the second mounting grooves 5 can be determined according to actual conditions, such as the length of the support plate 3. In the present embodiment, the number of the second mounting grooves 5 is five, and in order to ensure the uniformity of the subsequent force, the second mounting grooves 5 are symmetrically distributed in the first mounting groove 4, and the spacing between adjacent second mounting grooves 5 is the same. Through the above-mentioned setting, the symmetry of the distribution of the second mounting grooves 5 in the first mounting groove 4 can ensure the uniformity of the force of the support structure during the subsequent testing work.

[0024] A plurality of rollers 6 are fixedly sleeved on the roller body 2, and the number of rollers 6 can be set according to specific circumstances. Each roller 6 is sleeved on the roller body 2 on the shaft section of the roller body 2 in the second mounting groove 5, and the top wall of the roller 6 is arranged higher than the top wall of the support plate 3, so that when the sliding screen body m is tested, the roller 6 is used to replace the roller body 2 to test the sliding screen body m. In order to ensure the uniformity of force when the roller 6 is tested, the number of rollers 6 arranged in each second mounting groove 5 is arranged in the same manner. In this embodiment, the number of rollers 6 arranged in each second mounting groove 5 is 3, and at the same time, the distribution of the rollers 6 in the second mounting groove 5 is arranged symmetrically. Through the above-mentioned arrangement, the symmetry of the distribution of the rollers 6 in the second mounting groove 5 can ensure the uniformity of force on the working rollers 6 in subsequent tests.

[0025] The working principle of the utility model is that when testing the sliding screen body m, the two ends of the sliding screen body are pasted to the fixture platform, and then the sliding screen body m is repeatedly rolled by using the roller 6 of the supporting structure.

[0026] In this embodiment, the support plate 3 is made of elastic material, such as polyurethane, elastic plastic, elastic resin, etc. The first mounting groove 4 is arranged in an arc-shaped structure, and the first mounting groove 4 is connected with the roller body 2 in an embracing manner. Through the above-mentioned arrangement, the embracing connection method can ensure the stability of the connection between the roller body 2 and the first mounting groove 4, and the support plate 3 made of elastic material can be deformed under external force to provide a corresponding replacement space when the roller body 2 needs to be replaced.

[0027] In this embodiment, the roller 6 is made of PEEK material. PEEK material has excellent strength, high wear resistance and fatigue strength, can withstand high loads and frequent operations, and helps to improve the stability and life of the roller 6.

[0028] In order to prevent the roller body 2 from moving on the support plate 3, limiting screws 7 are provided on both side walls of the support plate 3, and threaded holes 8 are provided on both side walls of the support plate 3. The limiting screws 7 on both sides are threadedly connected with the threaded holes 8 on the corresponding sides to be arranged on the support plate 3, and the nut portion of the limiting screw 7 is arranged to abut against the end of the roller body 2 on the corresponding side. The setting of the limiting screws 7 on both sides can limit the left and right displacement of the roller body 2 on the support plate 3 by abutting against the two ends of the roller body 2, so as to prevent the roller body 2 from moving on the support plate 3.
