Description

Technical Field

[0001] This utility model relates to the technical field of roller shutter protective covers, specifically a roller shutter protective cover. Background Technology

[0002] Roller shutter protective covers are retractable protective devices that provide protection during equipment operation, preventing the intrusion of dust, chips, liquids, etc. They are widely used in machine tools, home furnishings, and other fields.

[0003] After the roller shutter protective cover is released, it usually rebounds quickly. If the operator is on the rebound path, their hands, arms or other parts of the body may be hit or pinched by the suddenly moving protective cover. Moreover, the rapid rebound can easily cause deformation, loosening or even direct breakage due to frequent violent impacts. To address this problem, we have proposed a roller shutter protective cover. Utility Model Content

[0004] The purpose of this invention is to provide a roller shutter protective cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller blind protective cover, comprising a roller blind frame, the inner wall of which is rotatably connected to a roller, one end of which is fixedly connected to a spiral spring, the other end of which is fixedly mounted on the outer wall of the roller, a roller blind panel fixedly mounted on the outer wall of the roller, the roller blind panel penetrating the roller blind frame and slidably connected to it, and a control component and a driven component disposed within the roller blind frame, the control component comprising:

[0006] A slider is connected to a roller via a vertical rod. The outer wall of the vertical rod is connected to the slider via a spring, which provides a springing force to the slider.

[0007] The movable plate has protrusions on its side for abutting against the slider to move it, a flat rod inside the movable plate for supporting its lateral movement, and a spring on the side of the movable plate for providing a springing force to the movable plate.

[0008] The limiting block is used to restrict the pop-up of the moving plate. The bottom of the limiting block is connected to the support block by a spring four. The spring three at the bottom of the support block provides the pop-up force to the support block, thereby limiting the rotation speed of the roller and preventing the roller rotation speed and the moving speed of the roller shutter from being too fast, which could cause accidental injury to the operator.

[0009] Preferably, the vertical rod is fixedly installed on the outer wall of the roller, the vertical rod passes through the slider and is slidably connected to the slider, the bottom of the slider is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly installed on the outer wall of the vertical rod. When the cut surface of the slider is no longer in contact, it will bounce off the surface of the vertical rod under the action of the first spring.

[0010] Preferably, the movable plate passes through the roller blind frame and is slidably connected to the roller blind frame. A protrusion is fixedly installed on the side of the movable plate, and a flat rod is fixedly installed on the inner wall of the roller blind frame. When the movable plate is subjected to force, it can make stable lateral movements along the inside of the roller blind frame.

[0011] Preferably, the flat rod passes through the movable plate and is slidably connected to the movable plate. The side of the movable plate is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly installed on the outer wall of the flat rod. When the movable plate is no longer under force, it will bounce off the flat rod under the action of the second spring.

[0012] Preferably, the inner wall of the movable plate is fixedly connected to one end of the spring three, and the other end of the spring three is fixedly installed at the bottom of the support block. When the support block is no longer under force, it will bounce off the movable plate under the action of the spring three.

[0013] Preferably, the inner wall of the support block is fixedly connected to one end of the spring four, and the other end of the spring four is fixedly installed at the bottom of the limiting block. When the cut surface of the limiting block is abutted, the spring four can be squeezed.

[0014] Preferably, the driven component includes a crossbar, which is fixedly installed on the inner wall of the support block. The crossbar passes through the locking rod and is slidably connected to the locking rod. The crossbar ensures the stability of the locking rod during lateral movement.

[0015] Preferably, the side of the movable plate has a horizontal groove and a vertical groove. When the locking rod is located in the horizontal groove, the longitudinal movement of the support block can be restricted.

[0016] Compared with the prior art, the present invention provides a roller shutter protective cover, which has the following beneficial effects:

[0017] 1. This roller shutter protective cover, through the installation of a control component, allows for the horizontal movement of a movable plate within the roller shutter frame. The movable plate moves along the surface of the horizontal rod, and the protrusions fixed to the side of the movable plate move towards the roller. When the roller rotates, the slider connected to the vertical rod on the roller surface will abut against the surface of the protrusions. When the slider is abutted, it will slide on the surface of the vertical rod, and a spring provides a spring-like force to the slider, thereby limiting the rotation speed of the roller and preventing the roller shutter from rotating too fast and causing accidental injury to the operator.

[0018] 2. This roller shutter protective cover, by being equipped with a driven component, can restrict the pop-up of the moving plate when the limiting block is locked on the side of the fixed block. Therefore, when the locking rod is located in the transverse groove, it can restrict the longitudinal movement of the support block and the limiting block, thereby achieving the purpose of secondary restriction on the pop-up of the moving plate and avoiding the situation where the moving plate pops up due to accidental contact during use.

[0025] like Figures 1-5As shown, this utility model provides a technical solution: a roller blind protective cover, including a roller blind frame 1, the inner wall of the roller blind frame 1 being rotatably connected to a roller 2, one end of a spiral spring 3 being fixedly connected to the inner wall of the roller blind frame 1, the other end of the spiral spring 3 being fixedly installed on the outer wall of the roller 2, a roller blind plate 4 being fixedly installed on the outer wall of the roller 2, the roller blind plate 4 penetrating the roller blind frame 1 and being slidably connected to the roller blind frame 1, a control component 6 and a driven component 7 being provided inside the roller blind frame 1, the control component 6 including: a vertical rod 61, a slider 62, a first spring 63, a protrusion 64, a moving plate 65, a horizontal rod 66, a second spring 67, a third spring 68, a support block 69, a fourth spring 610 and a limiting block 611, the slider 62 being connected to the roller 2 through the vertical rod 61, the outer wall of the vertical rod 61 being connected to the slider 62 through the first spring 63, the first spring 63 providing spring-like support for the slider 62. The moving plate 65 has a protrusion 64 on its side that abuts against the slider 62 to move it. The flat rod 66 inside the moving plate 65 supports its lateral movement. The second spring 67 on the side of the moving plate 65 provides a springing force to the moving plate 65. The limiting block 611 is used to limit the springing of the moving plate 65. The bottom of the limiting block 611 is connected to the support block 69 through the fourth spring 610. The third spring 68 at the bottom of the support block 69 provides a springing force to the support block 69. When the roller 2 rotates, the slider 62 connected to the vertical rod 61 on the surface of the roller 2 will abut against the surface of the protrusion 64. When the slider 62 is abutted, it will slide on the surface of the vertical rod 61. The first spring 63 provides a springing force to the slider 62, thereby limiting the rotation speed of the roller 2 and preventing the roller 2 and the roller shutter 4 from moving too fast, which could cause accidental injury to the operator.

[0026] A vertical rod 61 is fixedly installed on the outer wall of the roller 2. The vertical rod 61 passes through and is slidably connected to the slider 62. The bottom of the slider 62 is fixedly connected to one end of a spring 63. The other end of the spring 63 is fixedly installed on the outer wall of the vertical rod 61. When the cut surface of the slider 62 is no longer in contact, it will spring up from the surface of the vertical rod 61 under the action of the spring 63. A movable plate 65 passes through and is slidably connected to the roller blind frame 1. A protrusion 64 is fixedly installed on the side of the movable plate 65. A flat rod 66 is fixedly installed on the inner wall of the roller blind frame 1. When the movable plate 65 is under force, it can make stable lateral movements along the inside of the roller blind frame 1. A flat rod 66 passes through and is slidably connected to the movable plate 65. The side of the movable plate 65 is fixedly connected to one end of a spring 67. The other end of the spring 67 is fixedly installed on the outer wall of the flat rod 66. When the movable plate 65 is no longer under force, it will spring up from the inside of the flat rod 66 under the action of the spring 67. The inner wall of the movable plate 65 is fixedly connected to one end of spring three 68, and the other end of spring three 68 is fixedly installed at the bottom of the support block 69. When the support block 69 is no longer under force, it will spring up from the movable plate 65 under the action of spring three 68. The inner wall of the support block 69 is fixedly connected to one end of spring four 610, and the other end of spring four 610 is fixedly installed at the bottom of the limiting block 611. When the cut surface of the limiting block 611 is abutted, spring four 610 can be squeezed. The driven component 7 includes a crossbar 71, which is fixedly installed on the inner wall of the support block 69. The crossbar 71 passes through the locking rod 72 and is slidably connected to the locking rod 72. The crossbar 71 can ensure the stability of the locking rod 72 during lateral movement. A horizontal groove 73 and a vertical groove 74 are provided on the side of the movable plate 65. When the locking rod 72 is located in the horizontal groove 73, it can restrict the longitudinal movement of the support block 69.

[0027] In this invention, when the roller shutter panel 4 needs to be rolled up, the moving plate 65 is pushed along the side of the roller shutter frame 1. The moving plate 65 slides along the surface of the horizontal rod 66. The protrusion 64 fixed to the side of the moving plate 65 moves toward the roller 2. When the moving plate 65 moves toward the fixed block 5, the fixed block 5 abuts against the tangential surface of the limiting block 611. When the limiting block 611 is abutted, it will compress the spring 610. When it no longer abuts against the surface of the fixed block 5, it will spring up under the action of the spring 610 and lock onto the side of the fixed block 5, thus limiting the lateral springing of the moving plate 65. After limiting, the roller shutter panel 4 is released, and the roller 2 will reverse under the action of the spiral spring 3 to roll up the roller shutter panel 4. When the roller 2 rotates, the surface of the roller 2 is connected to the slider 62 by the vertical rod 61. When the slider 62 is pressed against the surface of the protrusion 64, it will slide on the surface of the vertical rod 61. The spring 63 provides the force for the slider 62 to bounce back, thereby limiting the rotation speed of the roller 2 and preventing the roller 2 and the roller shutter 4 from moving too fast and accidentally injuring the operator. When it is necessary to release the buffer structure, the locking rod 72 is moved in the support block 69 and moved out of the horizontal groove 73. After it is moved out, the locking rod 72 is pushed and the locking rod 72 moves longitudinally against the support block 69 through the horizontal rod 71. The support block 69 squeezes the spring 68. When the support block 69 moves, the limiting block 611 connected to the spring 610 in the support block 69 can move longitudinally. Then the moving plate 65 can bounce back under the action of the spring 67, so that the protrusion 64 is away from the roller 2, so that the roller shutter 4 can be quickly pulled out.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
