Description

Technical Field

[0001] This utility model relates to the field of roller shutter controller technology, specifically a roller shutter controller with bearings. Background Technology

[0002] The roller shutter controller with bearing disclosed in CN215718386U includes a ball bearing disc body, a main body, a tube plug, a first bearing disposed between the ball bearing disc body and the main body; a second bearing disposed between the main body and the tube plug to reduce rolling friction between the main body and the tube plug; a groove disposed on the outer wall of the tube plug; and an elastic boss disposed in the groove with one end of the boss fixedly connected to the outer wall of the tube plug.

[0003] It employs a first bearing and a second bearing respectively installed between the ball bearing disc body and the main body, and between the main body and the tube plug. This reduces the rolling friction between the ball bearing disc body and the main body, resulting in less resistance and easier pulling when the user pulls the ball.

[0004] The technical solution in the prior art has the effect of reducing rolling friction and reducing resistance when pulling the candle, but the defects are also more obvious. For example, because it is fixedly connected inside the bearing, it is more troublesome to disassemble when it needs to be replaced or maintained. This solution is also more complicated to disassemble the roller shutter controller. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a roller shutter controller with a bearing, which solves the problem that disassembly is troublesome when replacement and maintenance are required because the controller is fixedly connected inside the bearing, making the disassembly operation of the roller shutter controller cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller shutter controller with bearings, comprising a sleeve, a side plate provided on the side of the sleeve, a drive motor mounted on the side of the side plate, a rotating shaft provided at the output end of the drive motor, a bearing mounted at one end of the rotating shaft via a quick-release assembly, a back plate provided on the back of the bearing, and the back plate mounted at one end of the sleeve.

[0007] The quick-release assembly includes a sleeve installed at one end of the rotating shaft, and a sliding hole is provided on the top surface of the sleeve. A limiting structure is installed on the surface of the sliding hole. A slidable slide rod is provided inside the sleeve. A fixed fixing bead is installed at one end of the slide rod, and a slidable sliding bead is installed on the surface of the slide rod.

[0008] In one specific embodiment, the limiting structure includes a square tube installed on the top surface of the sliding hole, and a spring is provided inside the square tube, with a locking block provided on the bottom surface of the spring.

[0009] In one specific embodiment, the top surface of the rotating shaft is provided with a slot for placing the roller shutter, and rubber strips are provided on both sides inside the slot.

[0010] In one specific embodiment, a pressure plate is engaged inside the slot by a rubber strip, and grooves matching the rubber strip are provided on both sides of the pressure plate.

[0011] In one specific embodiment, both the side plate and the sleeve have screw holes on their sides, and bolts for installation are provided inside the screw holes.

[0012] In one specific embodiment, the bottom surface of the sleeve is provided with a sliding opening for the roll-up of the shutter, and the surface of the sleeve is provided with lines to improve its appearance.

[0013] Compared with the prior art, this utility model provides a roller shutter controller with bearings, which has the following advantages:

[0014] In the technical solution disclosed in this utility model, when it is necessary to disassemble, maintain or replace the roller blind controller, the inside of the sleeve can be exposed by disassembling the screw. Then, the rotating shaft can be pressed inward, and the rotating shaft can be easily disassembled through the quick-release assembly. This allows the roller blind or rotating shaft inside the roller blind controller to be replaced or maintained, thereby improving the maintenance and replacement efficiency of the roller blind controller.

[0015] By using the quick-release assembly of this invention, pressing the rotating shaft inward causes the sleeve at one end of the shaft to slide on the surface of the sliding rod. This moves the locking block inside the sleeve to the back of the sliding bean that is sliding on the surface of the sliding rod. Then, pulling the rotating shaft outward causes the locking block inside the sleeve to push the sliding bean to the back of the fixed bean. The sliding bean and the fixed bean form a complete sphere. Continuing to pull the rotating shaft causes the locking block inside the sleeve to quickly pass over the surfaces of the sliding bean and the fixed bean, completing the disassembly of the sleeve and thus disassembling the rotating shaft. This achieves the effect of convenient and quick disassembly of the rotating shaft inside the sleeve, reducing the complexity of the operation. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 In one embodiment of this utility model, a roller shutter controller with bearings includes a sleeve 1, a side plate 2 is provided on the side of the sleeve 1, and a drive motor 3 is installed on the side of the side plate 2. A rotating shaft 4 is provided at the output end of the drive motor 3, and a bearing 6 is installed at one end of the rotating shaft 4 through a quick-release assembly 5. A back plate 7 is provided on the back of the bearing 6 and is installed at one end of the sleeve 1.

[0024] The specific problem addressed in this embodiment is the cumbersome disassembly of the roller blind controller due to its fixed connection inside the bearing, making replacement and maintenance difficult. This invention utilizes a method where, when the roller blind controller needs disassembly, maintenance, or replacement, the screw can be removed to expose the inside of the sleeve 1. Then, the rotating shaft 4 can be easily disassembled via the quick-release assembly 5, allowing for the replacement or maintenance of the roller blind or rotating shaft 4 inside the controller. This significantly improves the efficiency of roller blind controller maintenance and replacement.

[0025] The quick-release assembly 5 includes a sleeve 51 installed at one end of the rotating shaft 4, and a sliding hole is provided on the top surface of the sleeve 51. A limiting structure 52 is installed on the surface of the sliding hole. A slidable slide rod 53 is provided inside the sleeve 51. A fixed fixing bead 54 is installed at one end of the slide rod 53, and a slidable sliding bead 55 is installed on the surface of the slide rod 53. In this specific embodiment, the limiting structure 52 includes a square tube 521 installed on the top surface of the sliding hole, and a spring 522 is provided inside the square tube 521. A locking block 523 is provided on the bottom surface of the spring 522. Pressing the rotating shaft 4 inward causes the sleeve 51 at one end of the rotating shaft 4 to slide on the surface of the slide rod 53, causing the locking block 523 inside the sleeve 51 to move to the back of the sliding bean 55 that is sliding on the surface of the slide rod 53. Then, pulling the rotating shaft 4 outward causes the locking block 523 inside the sleeve 51 to push the sliding bean 55 to move to fit against the back of the fixed bean 54. The sliding bean 55 and the fixed bean 54 form a complete sphere. Continuing to pull the rotating shaft 4 causes the locking block 523 inside the sleeve 51 to quickly pass over the surfaces of the sliding bean 55 and the fixed bean 54, completing the disassembly of the sleeve 51 and the rotating shaft 4. This achieves the effect of conveniently and quickly disassembling the rotating shaft 4 inside the sleeve 1, reducing the complexity of the operation.

[0026] In this specific embodiment, the top surface of the rotating shaft 4 is provided with a slot for placing the roller shutter, and rubber strips 8 are provided on both sides inside the slot. The slot is secured with a pressure plate 9 by the rubber strips 8, and grooves matching the rubber strips 8 are provided on both sides of the pressure plate 9.

[0027] By setting the pressure plate 9, one end of the roller blind can be placed inside the slot. Pressing the pressure plate 9 down will cause it to be engaged with the inside of the slot by the rubber strip 8, thus squeezing and fixing the roller blind for easy and quick installation.

[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
