Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of French doors, in particular to a segmented French door. Background Art
[0002] A French door refers to a door with hinges installed on the side of the door and opening inwards (left inwards, right inwards) or outwards (left outwards, right outwards). In order to increase the width of the French door when it is opened, it is generally set in multiple segments, most of which are set in two segments, and the two door bodies are driven to relatively contract and extend by means of a sprocket chain and a driving member in cooperation. If it is installed outdoors, due to the erosion of rainwater, the sprocket chain is prone to rust and stick to sundries, which easily leads to jamming when unfolding or shortening. Therefore, a segmented French door with an embedded telescopic drive structure is designed to avoid being eroded by wind and rain, ensure smooth unfolding and contraction, and solve the problem of jamming during unfolding and contraction caused by wind and rain erosion. Summary of the Utility Model

Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment:
[0022] Please refer to Figures 1-4 , a segmented swing door, including a door body 1 and a door body 2 that can be guided and slid into the door body 1. A shielding through groove is opened at the bottom of the door body 2. A driving end box 3 is provided at one end of the door body 2. A chain 4 is arranged in the shielding through groove, and one end of the chain 4 extends into the driving end box 3. A driving mechanism is arranged in the driving end box 3. Sprockets meshing with the chain 4 are rotatably connected to both the side of the shielding through groove far from the driving end box 3 and the inside of the driving end box 3. A fixed block 5 with its bottom fixedly connected to the door body 1 is fixedly installed on the chain 4. An anti-slip and anti-disengagement guiding and limiting mechanism is arranged between the door body 1 and the door body 2. A locking mechanism is arranged at the end of the door body 1 far from the driving end box 3.
[0023] Specifically, the driving mechanism includes a support plate fixedly installed in the driving end box 3. The sprocket located inside the driving end box 3 is rotatably connected to the support plate. A driving motor 10 for driving the rotation of the sprocket is also fixedly installed in the driving end box 3. Start the driving motor 10 to make the output shaft of the driving motor 10 rotate clockwise or counterclockwise, which is convenient to drive the sprocket on this side to rotate clockwise or counterclockwise, thereby conveniently driving the chain 4 to rotate clockwise or counterclockwise, and thus driving the fixed block 5 to move relative to the shielding through groove.
[0024] Specifically, the anti-slip and anti-disengagement guiding and limiting mechanism includes an upper anti-slip and anti-disengagement guiding and limiting component and a lower anti-slip and anti-disengagement guiding and limiting component. The upper anti-slip and anti-disengagement guiding and limiting component includes a top guiding chute 8 opened at the top of the second door body 2 and a plurality of top guiding rollers 9 that are slidably engaged with the top guiding chute 8 and rotatably connected to the top position of the first door body 1 near the driving end box 3. The lower anti-slip and anti-disengagement guiding and limiting component includes a side guiding through groove 7 opened at the bottom side of the first door body 1. A side guiding roller 6 that is rotatably connected to the second door body 2 is slidably engaged in the side guiding through groove 7. Through the cooperation of the top guiding chute 8 and the plurality of top guiding rollers 9, and the cooperation of the side guiding through groove 7 and the side guiding roller 6, it is convenient for the second door body 2 to slide relative to the first door body 1, improving the guiding stability of the upper and lower sides, and at the same time performing position limiting to prevent slipping off.
[0025] Specifically, the locking mechanism includes a cross bar 13 fixedly connected to a positioning vertical rod 12 at the bottom. Both sides of the cross bar 13 are vertically slidably engaged with the first door body 1. An over groove 15 is opened at the top of the positioning vertical rod 12. Above the cross bar 13, there is a rotating shaft 16 rotatably connected to the first door body 1. A positioning hook 17 adapted to the over groove 15 is fixedly installed at the bottom of the rotating shaft 16. Limiting chutes 14 for guiding and sliding engagement with the cross bar 13 are opened on both sides of the first door body 1. By rotating the rotating shaft 16, the positioning hook 17 can be rotated out of the over groove 15, so that the cross bar 13 can freely fall, facilitating the positioning vertical rod 12 to be inserted into a position for fixation, thereby locking the position of the first door body 1. Through the cooperation of the limiting chutes 14 and the cross bar 13, it is convenient to limit the lifting and sliding height of the cross bar 13.
[0026] Specifically, a counterweight block symmetrically arranged with the fixed block 5 is also fixedly installed on the chain 4. By setting the counterweight block, the overall force on the chain 4 is made uniform, avoiding the situation that the chain 4 is easily disengaged from the chain wheel due to uneven force.
[0027] Specifically, a plurality of universal wheels 11 are installed at the bottom of the first door body 1 and the bottom of the driving end box 3. Through the plurality of universal wheels 11, it is convenient to perform overall rotation and telescopic operations.
[0028] During use, a hinge can be installed at the end of the first door body 1 that is far from the driving end box 3 and installed on one side door post. Then, one of the sprockets can be driven by the driving mechanism, and then the chain 4 can be driven to rotate, thereby driving the fixed block 5 to move relative to the shielding through groove, so that the second door body 2 and the first door body 1 move relative to each other, thereby performing telescoping.
