DETAILED DESCRIPTION

[0019] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further detailed below with the drawings and specific embodiments. It should be explained that the embodiment of the present application and the features in the embodiment can be combined mutually without conflict.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a testing device for flame-retardant PVC cable sheath material, including a support plate 1 and a flame injector 2. A rotating cylinder 3 is rotatably connected to the support plate 1, a support frame 4 is fixedly connected to the rotating cylinder 3, an electric telescopic rod 5 is fixedly installed on the support frame 4, a push plate 6 is fixedly connected to the output end of the electric telescopic rod 5, and symmetrically arranged movable seats 7 are fixedly connected to the output end of the electric telescopic rod 5. A connecting rod 8 is hinged to each of the two movable seats 7. A mounting plate 9 is fixedly connected to the support frame 4. A through groove 10 is opened at the middle position of the mounting plate 9. Symmetrically arranged sliding grooves 11 are opened on the mounting plate 9. A guide rod 12 is fixedly connected inside each of the two sliding grooves 11. Symmetrically arranged hinge seats 13 are slidably connected inside each of the two sliding grooves 11. Clamping blocks 14 are fixedly connected to each of the multiple hinge seats 13.

[0022] like Figure 2 and Figure 3 As shown, a rubber layer is provided at the rotatable connection between the rotating cylinder 3 and the support plate 1. The tail end of the electric telescopic rod 5 passes through the rotating cylinder 3. The rotating cylinder 3 facilitates the rotation of the support mounting plate 9, the support frame 4 and the electric telescopic rod 5. The rubber layer provides great friction when the rotating cylinder 3 rotates, which facilitates the positioning of the rotating cylinder 3 after rotation and prevents the rotating cylinder 3 and the mounting plate 9 from rotating due to gravity.

[0023] like Figure 4 and Figure 5 As shown, the output end of the electric telescopic rod 5 passes through the through slot 10 and is fixedly connected to the push plate 6. The push plate 6 is specifically shaped as an annular plate. The electric telescopic rod 5 can easily drive the push plate 6 to move. When the output end of the electric telescopic rod 5 stops running, it will also drive the push plate 6 to stop running and be limited. When the push plate 6 moves, its annular part will push the cable sheath material held by the clamping block 14.

[0024] like Figure 3 As shown, all linkage rods 8 are hinged to hinge seats 13. The hinge seats 13 are slidably connected to guide rods 12 at positions corresponding to the inside of the slide groove 11. During the movement and rotation of linkage rods 8, the hinge seats 13 will be driven to complete the upward or downward movement. Guide rods 12 facilitate the movement of hinge seats 13 and limit the movement of hinge seats 13 within the inside of the slide groove 11 to prevent hinge seats 13 from disengaging from the slide groove 11. At the same time, the movement of hinge seats 13 facilitates the movement of clamping blocks 14 together.

[0025] likeFigure 1 And Figure 2 As shown in

[0026] As shown in Figure 1 And Figure 2 The top end of the base 15 is provided with a groove, and the flame gun 2 is placed in the groove on the base 15. When the flame gun 2 needs to be used, it can be directly taken out from the groove on the base 15. When the entire detection device is in a state of use, the flame gun 2 needs to be separated from the groove on the base 15 to prevent the flame from detonating the flame gun 2 during detection.

[0027] As shown in Figure 1 And Figure 4 The opposite surfaces of the clamping blocks 14 are provided with annular grooves. The specific shape and size of the clamping blocks 14 are the same. When the clamping blocks 14 move towards the middle at the same time, the cable sheath material can be clamped and limited through the annular grooves on the opposite surfaces. At this time, the cable sheath material is located in the annular grooves between the clamping blocks 14.

[0028] Specifically, when using this utility model, simply place the cable sheath material to be tested for flame retardancy on the two clamping blocks 14 at the bottom, and then activate the electric telescopic rod 5. When the output end of the electric telescopic rod 5 retracts, it will drive the push plate 6 and the two moving seats 7 to move towards the support plate 1. When the moving seats 7 move, they will pull one end of the connecting rod 8. At this time, the connection between the connecting rod 8 and the moving seat 7 will move with the moving seat 7. At the same time, the connecting rod 8, which is being pulled, will rotate around the connection with the moving seat 7 as the center during the movement. At this time, due to the movement and rotation of multiple connecting rods 8, the connection between the connecting rod 8 and the hinge seat 13 will rotate towards the center. At this time, each connecting rod 8 will simultaneously perform a closing rotation action towards the center. The rotation and closing of plate 8 will press the internal shaft of hinge seat 13. Under this pressure, hinge seats 13 will move towards the center, simultaneously driving clamping blocks 14 to move towards the center. At this time, hinge seats 13 and clamping blocks 14 simultaneously close. While hinge seats 13 slide within the slide groove 11, they are guided by guide rod 12, which restricts the movement of hinge seats 13 within the slide groove 11. The simultaneous closing of multiple clamping blocks 14 towards the center will collectively clamp and fix the cable sheath material. The cable sheath material is now located inside the annular grooves on opposite sides of each clamping block 14. The clamping blocks 14 have now fixed the cable sheath material. When a horizontal test of the cable sheath material is required, there is no need to rotate the mounting plate 9. Figure 1 At this point, the flamethrower 2 can be removed from the groove on the base 15, and the cable sheath material can be ignited directly using the flamethrower 2. The flame retardant data of the ignited cable sheath material can then be recorded. For vertical testing, the mounting plate 9 can be rotated forcefully. The rotation of the mounting plate 9 will cause the rotating cylinder 3 to rotate, which will rub against the rubber layer. Rotating the mounting plate 9 to a vertical angle will allow the flamethrower 2 to ignite the cable sheath material from the bottom. The flame retardant data of the cable sheath material under different water conditions can then be recorded. The flame retardant test data can be obtained by flattening the surface. After the test is completed, the electric telescopic rod 5 will reset each mechanism. The principle is the same. The electric telescopic rod 5 will drive the push plate 6 to move in the opposite direction to the support plate 1. At this time, each clamping block 14 is moving and opening in a direction away from each other. Finally, the moving push plate 6 will pass through the through groove 10 and push the cable sheath material down from the two clamping blocks 14 at the bottom. At this time, the cable sheath material is in a hot state. The push plate 6 pushes the cable sheath material down from the clamping blocks 14 to avoid the hot cable sheath material from injuring the staff.
