[0001] This utility model relates to the field of idler rollers, specifically an idler roller that is easy to position and install. Background Technology

[0002] Idler rollers are crucial components of belt conveyors, coming in various types and in large quantities. They support the conveyor belt and the weight of the materials. They account for 35% of the total cost of a belt conveyor and generate over 70% of the resistance, making their quality paramount. They are available in both steel and plastic.

[0003] The existing idler rollers lack a rigid positioning structure when docking with the drive source of the conveyor, which makes it difficult for the idler rollers to dock with the drive source, resulting in inconvenience during operation and difficulty in alignment and installation. Therefore, those skilled in the art have provided an idler roller that is easy to position and install in order to solve the problems mentioned in the background art. Utility Model Content

[0006] As a further embodiment of this utility model: both sides of the roller body are fixedly connected to L-shaped connecting plates, the top of the L-shaped connecting plate is provided with a sliding hole, the bottom of the sliding rod is fixedly connected to a brake screw, the outer wall of the brake screw is threaded with a nut, and the top of the nut is tightly fitted with the bottom of the L-shaped connecting plate.

[0007] As a further improvement of this utility model: both sides of the mounting bracket are fixedly connected to arc-shaped plates, the bottom of the arc-shaped plates are fixedly connected to support plates, and the arc-shaped plates are connected to the round holes.

[0008] As a further embodiment of this utility model: a connecting block is fixedly connected to the top of the roller body, and the connecting block is located between two connecting plates, and a magnetic suction ring is fixedly connected to the inner wall of the connecting block.

[0009] As a further improvement of this utility model: the mounting bracket is U-shaped and the positioning plate is arc-shaped.

[0010] As a further improvement of this utility model: the sliding rod passes through the L-shaped connecting plate, and the L-shaped connecting plate is located below the mounting hole.

[0011] As a further improvement of this utility model: the connecting frame is U-shaped, and the diameters of the semi-circular groove and the circular hole are the same.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The sliding rods will pull the two sliding rods closer together through tension. The two sliding rods will pull the two connecting frames closer together. Then, the connecting frames will drive multiple positioning plates to clamp and fix the two idlers to be installed on both sides. Then, the two nuts will be rotated again to reset and stick to the bottom of the L-shaped connecting plate to brake the brake screw. This will fix the multiple connecting frames. At this time, the multiple positioning plates will be completely fixed, thus preventing the idlers to be installed from moving left and right. After pushing the two idlers to be installed away from each other, the idlers to be installed will be pushed out of the round hole along the round hole. At this time, the extended part can be supported by the arc plate.

[0014] This invention is simple to use. The roller to be installed is attracted by the magnetic ring, and then the two positioning plates are fixed and clamped on both sides of the roller to be installed, thereby positioning the roller. After pushing the two rollers to be installed out of the round hole, they can be connected and installed with the drive source. This completely fixes the position of the roller to be installed, which facilitates the connection between the drive source and the roller to be installed, thus facilitating the positioning and installation of the roller.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the utility model, an idler roller that is easy to position and install includes two idler roller bodies 1. The top of the two idler roller bodies 1 is fixedly connected to the same mounting frame 2. The top of the mounting frame 2 is symmetrically fixedly connected to two connecting plates 9, and the top of the connecting plates 9 is provided with a semi-circular groove 8. One side of the mounting frame 2 is provided with a through mounting hole 14, and two sliding rods 13 are slidably connected through the mounting hole 14. The opposite ends of the two sliding rods 13 are fixedly connected to the same tension spring 15. The top of the sliding rods 13 is fixedly connected to a connecting frame 6, and the opposite sides of the two connecting frames 6 are symmetrically fixedly connected to two positioning plates 7. Two circular holes 3 are provided through the two sides of the mounting frame 2, and the idler rollers 19 to be installed are fitted into the semi-circular grooves 8.

[0023] In this embodiment, L-shaped connecting plates 12 are fixedly connected to both sides of the roller body 1. A sliding hole 16 is provided through the top of the L-shaped connecting plate 12. A brake screw 17 is fixedly connected to the bottom of the sliding rod 13. A nut 18 is threaded on the outer wall of the brake screw 17, and the top of the nut 18 and the bottom of the L-shaped connecting plate 12 are tightly fitted. The two connecting plates 9 can be supported by placing a roller 19 to be installed in each of the semi-circular grooves 8. The parts of the two rollers to be installed that are close to each other can be attached to the magnetic ring 10. The magnetic ring 10 will attract and fix the rollers to be installed to prevent them from moving. Rotating the two nuts 18 can release the brake on the two brake screws 17. Then, pulling the two sliding rods 13 away from each other can drive the two connecting frames 6 and the positioning plate 7 away from each other.

[0024] In this embodiment, arc-shaped plates 4 are fixedly connected to both sides of the mounting bracket 2, and a support plate 5 is fixedly connected to the bottom of the arc-shaped plates 4. The arc-shaped plates 4 are connected to the circular holes 3.

[0025] In this embodiment, a connecting block 11 is fixedly connected to the top of the roller body 1, and the connecting block 11 is located between two connecting plates 9. A magnetic suction ring 10 is fixedly connected to the inner wall of the connecting block 11.

[0026] In this embodiment, the mounting bracket 2 is U-shaped and the positioning plate 7 is arc-shaped. When the two sliding rods 13 move closer to each other, they will pull the two connecting brackets 6 closer to each other. Then, the connecting brackets 6 will drive the multiple positioning plates 7 to clamp and fix the two rollers 19 to be installed on both sides. Then, the two nuts 18 are rotated again to reset and stick to the bottom of the L-shaped connecting plate 12 to brake the brake screw 17. In this way, the multiple connecting brackets 6 can be fixed.

[0027] In this embodiment, the sliding rod 13 passes through the L-shaped connecting plate 12, and the L-shaped connecting plate 12 is located below the mounting hole 14.

[0028] In this embodiment, the connecting frame 6 is U-shaped, and the semi-circular groove 8 and the circular hole 3 have the same diameter.

[0029] The working principle of this utility model is as follows: Two connecting plates 9 can be supported by placing one roller 19 to be installed in each of the semicircular grooves 8. The parts of the two rollers 19 close to each other can adhere to the magnetic ring 10, which will attract and fix the rollers 19 to prevent movement. Rotating the two nuts 18 releases the brakes on the two brake screws 17. Then, pulling the two sliding rods 13 away from each other will cause the two connecting frames 6 and the positioning plate 7 to move away from each other. At this time, the tension spring 15 will be stretched. Then, releasing the sliding rods 13 will cause the two sliding rods 13 to pull closer together through the pulling force. When the two sliding rods 13 move closer together, they will pull the two connecting frames 6 closer together. Then, the connecting frames 6 will drive multiple positioning plates 7 to clamp and fix the two rollers 19 to be installed on both sides. Then, the two nuts 18 will be rotated again to reset and stick to the bottom of the L-shaped connecting plate 12 to brake the brake screw 17. This will fix the multiple connecting frames 6. At this time, the multiple positioning plates 7 will be completely fixed, thus preventing the rollers 19 to be installed from moving left and right. After pushing the two rollers 19 to be installed away from each other, the rollers 19 to be installed will be pushed out of the circular hole 3 along the circular hole 3. At this time, the extended part can be supported by the arc plate 4.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
