[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This easy-to-install roller frame is equipped with a cam locking structure. The roller shaft assembly is placed on the lower half bearing of the bearing seat base, and the bearing seat cover is placed on the shaft assembly, aligning the upper and lower half bearings to form a complete bearing support system. Fixing is achieved by operating the cam locking structure. Rotating the rotating rod causes the connecting rod to be located in the groove. The connecting rod is connected to the rotating rod through a threaded rod, thereby adjusting the overall length of the connecting rod and the rotating rod. When the cam handle is rotated, its eccentric cam part pushes the pressure plate downward through the rotating shaft, thereby driving the pressure plate to press the bearing seat cover downward.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides an embodiment of a roller frame for easy installation of roller bodies, including a roller body 1, a bearing seat base 2, a bearing seat cover 3, a cam locking structure 4, and a limiting structure 5. A shaft assembly 11 is fixedly connected to the middle of the roller body 1. The top of the bearing seat base 2 is snapped into the bearing seat cover 3. Both ends of the shaft assembly 11 are rotatably connected to the bearing seat base 2 and the bearing seat cover 3. The cam locking structure 4 includes a rotating shaft 41 and a connecting rod 43. Grooves are provided at both the left and right ends of the bearing seat base 2, and the inner wall of the groove of the bearing seat base 2 is rotatably connected to the lower half bearing 2. 1. The lower half bearing 21 is rotatably connected to the rotating rod 42. The bottom of the connecting rod 43 is fixedly connected to the threaded rod 44. The threaded rod 44 is threadedly connected to the rotating rod 42. The top of the connecting rod 43 is rotatably connected to the rotating shaft 45. The rotating shaft 45 is rotatably connected to the cam handle 46. The connecting rod 43 is slidably connected to the clamping plate 48. The limiting structure 5 includes the rotating shaft 51. The left and right sides of the bearing seat base 2 are fixedly connected to the rotating shaft 51. The rotating shaft 51 is rotatably connected to the rotating seat 53. The top of the rotating seat 53 is fixedly connected to the baffle 54. The outer wall of the baffle 54 is fixedly connected to the magnet 55.
[0023] Furthermore, the lower half bearing 21 is fixedly connected to the top of the bearing seat base 2, and the upper half bearing 31 is fixedly connected to the bottom of the bearing seat cover 3. This split bearing seat design makes the installation and disassembly of the roller body 1 extremely convenient. The combination of the upper and lower half bearings 21 provides stable support for the shaft assembly 11.
[0024] Furthermore, a magnet 47 is fixedly connected to the outer wall of the cam handle 46. The positions of magnet 47 and magnet 55 are corresponding. The magnets attract each other and can firmly lock the cam handle in the closed position, effectively preventing the locking structure from accidentally loosening due to vibration during equipment operation.
[0025] Furthermore, a rubber pad 49 is fixedly connected to the bottom of the clamping plate 48. The bottom surface of the rubber pad 49 is provided with uneven patterns. The rubber pad 49 can increase the friction with the bearing seat cover and play a buffering role. Its surface patterns further enhance the anti-slip effect and ensure reliable clamping.
[0026] Furthermore, a limiting plate 52 is fixedly connected to the outer wall of the rotating shaft 51. The diameter of the limiting plate 52 is larger than the diameter of the rotating shaft 51. As a mechanical stop, the limiting plate 52 can precisely control the rotation angle of the baffle 54, preventing it from rotating excessively and affecting the alignment and attraction of the magnet.
[0027] Furthermore, grooves are provided at both ends of the bearing housing cover 3, and the rotating rod 42 and the connecting rod 43 are slidably connected to the grooves of the bearing housing cover 3. The grooves provide guidance and accommodation space for the movement of the locking mechanism, ensuring smooth and stable operation and making the overall structure more compact.
[0028] Furthermore, the cam handle 46 is an L-shaped rod, with one end of the cam handle 46 being an eccentric cam and the other end being a grip, and the surface is provided with an anti-slip coating. The L-shaped design utilizes the lever and eccentric cam principle to increase force, making operation easier, while the anti-slip coating ensures that the handle will not slip when a large force is applied.
[0029] Working principle: In use, firstly, place the shaft assembly 11 of roller body 1 on the lower half bearing 21 of bearing seat base 2, and cover the shaft assembly 11 with the bearing seat cover 3, aligning the upper half bearing 31 with the lower half bearing 21 to form a complete bearing support system. Fixing is achieved by operating the cam locking structure 4. Rotating the rotating rod 42 causes the connecting rod 43 to be located in the groove of 3. The connecting rod 43 is connected to the rotating rod 42 through the threaded rod 44, thereby adjusting the overall length of the connecting rod 43 and the rotating rod 42. When rotating the cam handle 46, its eccentric cam part pushes the pressure plate 48 downward through the rotating shaft 45, thereby driving the pressure plate 48 to press downward. The rubber pad 49 at the bottom of the bearing seat cover 3 and the pressure plate 48 provides soft contact to ensure uniform pressing. The cam handle 46 uses the principle of eccentric cam to generate a strong pressing force to firmly fix the bearing seat cover 3 and the bearing seat base 2, ensuring that the roller 1 does not loosen during operation. During the locking process, the limiting structure 5 takes effect. Rotating the rotating seat 53 causes the baffle 54 to flip upward, so that the baffle 54 blocks 46. The magnet 47 on the cam handle 46 and the magnet 55 on the baffle 54 are attracted to each other, fixing the baffle 54 in the locked position. The attraction of the magnet 47 and the magnet 55 in the limiting structure 5 provides additional locking to prevent accidental opening.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
