Description

Technical Field

[0001] This utility model relates to a safety locking device, specifically a child safety lock hand-operated windproof roller shutter. Background Technology

[0002] With the continuous improvement of people's living standards, windproof roller blinds are widely used in various residential, commercial buildings and office spaces for sun shading, wind protection, theft prevention, and enhancing the aesthetics of the space. Traditional roller blinds are usually raised and lowered by pulling a cord or by electric means. Although they can meet the basic opening and closing functions, they still have some obvious shortcomings in actual use.

[0003] First, most existing roller blind systems do not consider the safety of children in the home, making them prone to accidental descent or detachment due to children's accidental touch or operation, potentially causing injuries such as pinching, posing a significant safety risk. This is especially true in the home environment, where children's active nature exacerbates the safety concerns of roller blind equipment.

[0004] Secondly, the windproof performance of roller blinds on the market usually relies on the strength of the roller blind material itself or the simple limiting structure of the side rails, lacking effective structural windproof fixing measures. This makes the roller blinds prone to swaying, derailment or even damage when encountering strong winds, affecting their normal service life and residential safety.

[0005] In addition, traditional roller blinds are relatively simple in terms of positioning and locking operation, usually relying on manual pins or buckle mechanisms. They are inconvenient to operate, the locking and unlocking process is cumbersome, and they are prone to jamming or failure due to long-term use, which is not conducive to high-frequency daily use. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a child safety lock-operated hand-push windproof roller shutter that enables rapid double-sided locking of the side rails. It is simple to operate, safe, and reliable, effectively overcoming the shortcomings of existing technologies.

[0007] This utility model is achieved through the following technical solution: a child safety lock hand-push windproof roller shutter, comprising:

[0008] The lower beam is installed between the side rails, with a windproof roller shutter installed at the top of the lower beam and sealing plugs installed on both sides of the lower beam;

[0009] A side rail locking mechanism is provided on both sides of the lower beam to lock the position of the lower beam in the height direction of the side rail;

[0010] A lower beam damping lock is installed on the lower beam. By rotating the lower beam damping lock, the side rail locking mechanisms on both sides can be extended or retracted.

[0011] A locking switch is installed on a fixed panel outside the lower beam damping lock, and the locking switch is used to lock the degree of freedom of the lower beam damping lock in the circumferential direction.

[0012] As a preferred technical solution, the side rail locking mechanism includes a left push rod and a right push rod. A left locking head is installed on the side of the left push rod away from the lower beam damping lock, and a right locking head is installed on the side of the right push rod away from the lower beam damping lock. The left and right locking heads are retracted into the sealing plug.

[0013] A drive connection bracket is installed on the side of the left push rod and the right push rod away from the left locking head and the right locking head, respectively. The drive connection bracket is driven to reciprocate along the length direction of the left push rod and the right push rod by the circumferential rotation of the lower beam damping lock.

[0014] As a preferred technical solution, the lower beam damping lock includes a lock body knob, a rotary locking component, a limiting fixing block, and a hinged drive block. The bottom of the lock body knob is assembled with the rotary locking component. The limiting fixing block is located at the bottom of the rotary locking component. Two hinged drive blocks are provided, each corresponding to a drive connection bracket. The hinged drive blocks are installed inside the limiting fixing block, and the bottom of the rotary locking component is hinged to one end of each hinged drive block. The other end of the hinged drive block is hinged to the drive connection bracket.

[0015] As a preferred technical solution, the drive connection bracket has a hinge protrusion on one side of the hinge drive block. One end of the hinge drive block is hinged to the hinge protrusion via a first hinge shaft. The other end of the hinge drive block is fixedly provided with a second hinge shaft, which passes through the limiting and fixing block and is positioned and connected to the rotation locking member.

[0016] As a preferred technical solution, the limiting and fixing block is provided with an arc-shaped track groove corresponding to the position of the second hinge shaft, and the second hinge shaft passes through the arc-shaped track groove and is positioned and connected to the rotating locking member.

[0017] As a preferred technical solution, the bottom of the locking switch is provided with a locking pin, and the outer surface of the rotating locking member is provided with multiple pin locking grooves. When the locking pin is inserted into the pin locking groove, the rotating locking member is locked.

[0018] As a preferred technical solution, a positioning spring is provided on the limiting fixing block in the circumferential direction of the rotating locking member. A spring positioning groove is provided on the outer circumference of the rotating locking member corresponding to the position of each pin locking groove. The positioning spring is V-shaped and is fixed on the spring mounting block and limited by a screw at the top.

[0019] The beneficial effects of this utility model are: by integrating a lower beam damping lock, a side rail locking mechanism and a locking switch into the lower beam structure, this utility model can achieve quick locking and unlocking operations and prevent children from accidentally operating the roller blind, thereby effectively improving the safety of children in the home environment and reducing the occurrence of accidents.

[0020] With the side rail locking mechanism design, after the roller blind descends to the appropriate position, the locking heads of the left push rod and the right push rod can be locked into the side rail respectively, realizing the firm limit of the lower beam, effectively preventing the roller blind from swaying, derailing or being damaged in strong winds, and significantly improving the overall windproof performance and durability.

[0021] This utility model adopts a push-type structure design, combined with an internal damping lock and a rotary locking mechanism. Users can quickly lock and release the roller shutter through the knob. The operation is simple and smooth, improving the convenience and efficiency of use, and is suitable for daily high-frequency operation. Attached Figure Description

[0032] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0033] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0034] like Figures 1-3 As shown, a child safety lock push-operated windproof roller shutter includes a lower beam 1, a windproof roller shutter, sealing plugs 10, a side rail locking mechanism, a damping lock on the lower beam 1, and a locking switch 11. The lower beam 1 is installed between the side rails, and a windproof roller shutter is installed at the top of the lower beam 1 to realize the lifting and lowering function of the roller shutter. Sealing plugs 10 are installed at both ends of the lower beam 1 to seal and protect the internal structure of the lower beam 1 and to serve as the extension space for the side rail locking mechanism.

[0035] The side rail locking mechanism is installed on both sides of the lower beam 1 to lock the position of the lower beam 1 in the height direction of the side rail, thereby preventing the lower beam 1 from moving up and down during use.

[0036] like Figures 4-7 As shown, the side rail locking mechanism includes a left push rod 2 and a right push rod 3. Each push rod has a left locking head 9 and a right locking head 8 respectively installed at the end furthest from the damping lock of the lower beam 1. When unlocked, the left locking head 9 and right locking head 8 retract into their corresponding sealing plugs 10. The ends of both the left push rod 2 and the right push rod 3 furthest from the locking heads are connected to drive connecting brackets 7 to receive the driving force from the damping lock of the lower beam 1, thus achieving synchronous reciprocating motion of the push rods.

[0037] The lower beam 1 damping lock is installed in the middle of the lower beam 1 and is used to control the extension and retraction of the side rail locking mechanism. The lower beam 1 damping lock includes a lock body knob 6, a rotary locking component 13, a limiting fixing block 4, and a hinged drive block 5. The bottom of the lock body knob 6 is assembled and connected to the rotary locking component 13. By manually turning the lock body knob 6, the rotary locking component 13 can be driven to rotate synchronously. The limiting fixing block 4 is connected to the lower part of the rotary locking component 13. Two hinged drive blocks 5 corresponding to the left and right push rods are provided in the limiting fixing block 4. One end of each hinged drive block 5 is hinged to the hinge protrusion 71 on the drive connection bracket 7 through the first hinge shaft 72, and the other end is fixed with a second hinge shaft 51. The second hinge shaft 51 passes through the limiting fixing block 4 and is positioned and connected to the rotary locking component 13.

[0038] An arc-shaped track groove 41 is provided on the limiting fixing block 4 at the position corresponding to the second hinge shaft 51, so that the second hinge shaft 51 can move along the arc-shaped track groove 41 under the drive of the rotating locking member 13. When the lock body knob key 6 is manually turned, the lock body knob key 6 drives the rotating locking member 13 to rotate synchronously. The rotating locking member 13 drives the second hinge shaft 51 to move along the arc-shaped track groove 41, thereby pushing the hinge drive block 5 to swing. The movement of the hinge drive block 5 further drives the connected drive connecting bracket 7 to move linearly along the length direction of the left push rod 2 and the right push rod 3, so that the left push rod 2 and the right push rod 3 move outward.

[0039] As the left push rod 2 and the right push rod 3 are pushed out, the left locking head 9 and the right locking head 8, which are respectively located at the ends of the push rods, are also pushed out, pass through the sealing plug 10 and are inserted into the side rail, thereby locking the lower beam 1 in the height direction of the side rail, preventing the lower beam 1 from moving up and down due to external force, and enhancing the overall stability and windproof performance of the roller shutter.

[0040] To further prevent locking failure due to misoperation, this utility model has a locking switch 11 installed on the external fixing panel of the damping lock of the lower beam 1.

[0041] The locking switch 11 has a locking pin 12 at its bottom, and the outer circumference of the rotating locking member 13 has a plurality of pin locking grooves 14 corresponding to it. When the locking switch 11 is pushed, the locking pin 12 is inserted into the pin locking grooves 14 of the rotating locking member 13, restricting the rotational freedom of the rotating locking member 13, thereby locking the damping lock of the lower beam 1, preventing accidental rotation of the lock body knob 6, and further ensuring the stable locking of the lower beam 1.

[0042] In addition, a positioning spring 15 is provided on the limiting and fixing block 4. The positioning spring 15 is V-shaped and is fixedly installed on the spring mounting block and limited by the top screw. The outer circular surface of the rotating locking component 13 is provided with a spring positioning groove 16 at the position corresponding to each pin locking groove 14. When the rotating locking component 13 is rotated to each locking position, the V-shaped positioning spring 15 can automatically engage in the spring positioning groove 16, which plays the role of pre-positioning and auxiliary locking, so that the lock body knob 6 has a good tactile feedback and stability during rotation, improving the user experience.

[0043] This invention allows for smooth control of the left and right push rods 3 by manually rotating the lock body knob 6, enabling the extension and retraction of the left locking head 9 and the right locking head 8, thereby facilitating the rapid locking and releasing of the lower beam 1 within the side rail. Simultaneously, the locking switch 11 and positioning spring 15 mechanism effectively prevent accidental activation or vibration-induced locking failure, ensuring the reliability and stability of the roller shutter in terms of windproofing, tensile strength, and child safety.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
