Description

Technical Field

[0001] The utility model relates to the technical field of sunshade curtains, in particular to a linkage structure of sunshade curtains. Background Art

[0002] Car sunshades are usually installed on the roof to block the sunlight and thus reduce the temperature inside the car. Traditional sunshades include a frame, and a skylight cover and a winding roller at both ends of the frame. The winding roller has a built-in torsion spring for winding up the skylight cover. The skylight cover is provided with a handle rod for grabbing. When moving the skylight cover, if the grabbing part is not in the center of the handle rod, the overall force on the handle rod will be uneven, causing the handle rod to tilt relative to the frame and become stuck, thereby affecting the feel when pulling the sunshade. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a linkage structure of a sunshade, including a frame, and a canopy cover, a winding roller and a clamping piece arranged on the frame, and the frame puts the canopy cover in a closed state or a storage state through the winding roller, the canopy cover is provided with a handle rod for pulling, and also includes a pull rope connected end to end, and a front pulley seat and a rear pulley seat arranged on both sides of the frame, the pull rope is distributed on both sides of the handle rod through the front pulley seat and the rear pulley seat, and the pull ropes located at both ends of the handle rod have the same moving direction, and both ends of the handle rod are fixedly connected to the same pull rope.

[0004] By adopting the above technical solution, both ends of the handle rod are fixed on the same pull rope at the same time, and the pull rope is combined with the front pulley seat and the rear pulley seat to make the pull ropes at both ends of the handle rod move in the same direction and with the same amount of movement. When the handle rod is pulled to move the skylight cover, the hand acts on any position of the handle rod and moves under the action of the pull rope, and the direction of the handle rod remains unchanged, thereby avoiding the handle rod from tilting and getting stuck, thereby maintaining the stability of the structure.

[0005] The utility model is further configured such that the front pulley seat is provided with pulley a / pulley a′, the rear pulley seat is provided with pulley b / pulley b′, pulley c / pulley c′ and pulley d / pulley d′, and the pull rope passes through pulley a, pulley b, pulley c, pulley c′, pulley a′, pulley b′, pulley d′, pulley d, and pulley a in sequence, being connected end to end.

[0006] Furthermore, a T-shaped portion for connecting to a frame is provided at the bottom of the front pulley seat / rear pulley seat.

[0007] By adopting the above technical solution, a total of two groups of front pulley seats and four groups of rear pulley seats are distributed in a mirror-like manner on each frame, and rear pulley seats are distributed in a mirror-like manner on both ends of the winding roller, and pulleys b, pulley c, pulley d and pulleys b′, pulley c′, pulley d′ are installed respectively. There are two paths for the pull rope between pulley a and pulley a′, including from pulley a through pulley b, pulley c, pulley c′ to pulley a′, and from pulley a′ through pulley b′, pulley d′, pulley d to pulley a, so that the pull rope is distributed in a U shape on the frame as a whole, and will not block the view of the skylight.

[0008] The utility model is further configured that the front pulley seat / rear pulley seat is provided with a rotating shaft for installing the pulley, and a mounting portion and a T-slot for connecting the two ends of the rotating shaft, and the T-slot is provided with a protrusion for limiting.

[0009] When adopting the above technical solution, during installation, the rotating shaft is preferentially passed through the pulley, and the pulley is placed in the corresponding groove of the front pulley seat / rear pulley seat. The head and tail ends of the rotating shaft are respectively aligned and pushed into the installation part and the T-slot, so that the rotating shaft is stuck in the protrusions on both sides of the T-slot, thereby preventing the rotating shaft from detaching from the front pulley seat / rear pulley seat.

[0010] The utility model is further configured that the mounting parts at both ends of the front pulley seat are provided with first opening grooves with openings facing opposite directions, and the pulley a / pulley a′ is rotatably connected between the T-shaped groove and the first opening groove through a rotating shaft.

[0011] By adopting the above technical solution, mounting parts are symmetrically distributed at both ends of the front pulley seat. Under the action of the pull rope, a force is always applied to the rotating shaft toward the mounting part to prevent the rotating shaft from detaching from the front pulley seat in the direction of the opening of the first opening groove. The structural design is reasonable and the structure is stable.

[0012] The utility model is further configured that the rear pulley seat is provided with a transfer portion below the mounting portion, and the mounting portions at both ends of the rear pulley seat are provided with a second opening groove and a third opening groove with openings facing perpendicularly.

[0013] Furthermore, the pulley b is arranged between the second opening groove and the transition part, the pulley b′ is arranged between the transition part and the T-slot, the pulley c / pulley c′ is arranged between the third opening groove and the transition part, and the pulley d / pulley d′ is arranged below the pulley c / pulley c′.

[0014] By adopting the above technical solution, mounting parts are symmetrically distributed at both ends of the rear pulley seat. Under the action of the pull rope, a force is applied to pulley c, pulley c′, pulley d, and pulley d′ to tilt inward, while the opening direction of the third opening groove faces outward, thereby preventing the rotating shaft from detaching from the rear pulley seat in the direction of the opening of the third opening groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Both ends of the handlebar are fixed on the same pull rope, and the pull rope moves in the same direction and amount through the combined action of the front pulley seat and the rear pulley seat, thereby preventing the handlebar from tilting and getting stuck during movement and maintaining the stability of the structure.
