Description

Technical Field

[0001] The utility model relates to the technical field of folding doors, in particular to an anti-pinch folding door. Background Art

[0002] In the long-term development of the folding door technology field, although folding doors are widely used in various occasions such as homes, commercial and industrial due to their unique space utilization advantages and convenient opening methods, a significant problem in the use of traditional folding doors cannot be ignored - the risk of pinching hands.

[0003] A folding door, as a type of door with multiple panels that can be folded and pushed to the side to expand the passage space, mainly consists of a door frame, door panels, rotating components, swivel arm components, transmission rods, and orientation devices. In daily use, due to the gaps between the door panels and the rapid movement during opening and closing, especially at the opening part of the frame and panels, it is extremely easy to accidentally pinch fingers. Summary of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide an anti-pinch folding door, which solves the problems raised in the above background.

[0006] (II) Technical Solution

[0007] The anti-pinch folding door includes a first door body and a second door body. The first door body and the second door body are connected by multiple groups of first hinges. Moreover, multiple groups of second hinges are installed on one side of the first door body. Both ends of one side of the second door body are provided with installation grooves, and multiple groups of second springs are installed on the inner wall of the installation grooves. One end of each of the multiple groups of second springs is connected to a telescopic plate, and the telescopic plate is parallel to the outer surface of the second door body. Ring-shaped through grooves are provided on the outer surfaces of the upper and lower ends of the second door body, and a buffer mechanism is arranged on the inner wall of the ring-shaped through grooves.

[0008] Preferably, the buffer mechanism includes a circular plate, and the circular plate is fixedly installed in the inner wall of the ring-shaped through groove. One side of the ring-shaped through groove is connected to a damper, and one end of the damper is connected to a telescopic rod. The combined use of the damper and the telescopic rod enables the door body to achieve a smooth transition during the closing process. The damper can adjust the moving speed of the telescopic rod as needed, so as to slow down the speed of the door body when the door bodies are about to merge, achieving a soft landing and avoiding generating noise and vibration.

[0009] Preferably, a first spring is connected between the telescopic rod and the circular plate. When the door body is impacted during the closing process, the first spring can absorb and disperse part of the energy, thereby reducing the impact on the door body and the surrounding environment, making the door body more stable when closing, and reducing the generation of noise and vibration.

[0010] Preferably, a rubber pad is fixedly installed at one end of the telescopic rod. The rubber pad serves as a buffer layer for the telescopic rod to contact the door body, which can reduce the impact force generated when the door body closes. The elastic property of the rubber can absorb part of the energy, making the door body merge more gently, avoiding direct hard impacts, reducing noise and vibration, and also protecting the surface of the door body from being scratched or damaged.

[0011] Preferably, the outer end of the telescopic plate is arc-shaped. The arc-shaped design makes the outer end of the telescopic plate smoother, reducing the sharpness when contacting with hands or other objects. This design not only improves the safety of use, preventing scratches or pinches caused by sharp corners, but also makes the appearance of the door body more beautiful and harmonious.

[0012] Preferably, the outer surface of the telescopic plate is wrapped with rubber. The rubber wrapping not only increases the softness and elasticity of the telescopic plate, but also improves its wear resistance and corrosion resistance, enabling the telescopic plate to better maintain its shape and performance during long-term use and not being easily deformed or damaged.

[0013] Preferably, multiple groups of the second hinges are used to connect the door frame. The design of multiple groups of second hinges makes the connection between the door body and the door frame more stable and reliable.

[0014] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0015] 1. The utility model assists in controlling the closing speed of the door body by holding the telescopic plate, enabling the user to adjust the closing speed of the door body according to their own needs, improving the convenience and flexibility of use. Even if the door body closes relatively fast, the telescopic plate can automatically adjust its position under the action of external force and maintain a safe distance from the fingers, thus greatly reducing the risk of pinching fingers.

[0016] 2. The utility model effectively reduces the impact force when the door body merges through the combined action of the damper, the first spring, and the rubber pad in the buffer mechanism. When the two door bodies are about to merge, the telescopic rod moves slowly under the resistance of the damper, while the first spring plays a buffering role, and the rubber pad provides additional buffer protection when the door body is completely closed, thereby reducing the noise and vibration generated by the direct collision of the door body.

It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the implementation manner of the present disclosure, and does not necessarily show the specific dimensions and their ratios of each implementation manner of the present disclosure.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0025] A pinch-proof folding door, including a first door body 1 and a second door body 2. The first door body 1 and the second door body 2 are connected by multiple groups of first hinges 3, and multiple groups of second hinges 4 are installed on one side of the first door body 1. Installation grooves 6 are opened on both sides at one end of the second door body 2, and multiple groups of second springs 611 are installed on the inner wall of the installation grooves 6. One end of the multiple groups of second springs 611 is connected to a telescopic plate 5, and the telescopic plate 5 is parallel to the outer surface of the second door body 2. Annular through grooves 9 are opened on the outer surfaces of the upper and lower ends of the second door body 2, and a buffer mechanism is arranged on the inner wall of the annular through grooves 9.

[0026] Furthermore, the buffer mechanism includes a circular plate 911, and the circular plate 911 is fixedly installed in the inner wall of the annular through groove 9. One side of the annular through groove 9 is connected to a damper 912, and one end of the damper 912 is connected to a telescopic rod 7. The combined use of the damper 912 and the telescopic rod 7 enables the door body to achieve a smooth transition during the closing process. The damper 912 can adjust the moving speed of the telescopic rod as needed, so as to slow down its speed when the door bodies are about to merge, achieve a soft landing, and avoid generating noise and vibration.

[0027] Further, a first spring 913 is connected between the telescopic rod 7 and the circular plate 911. When the door body is impacted during the closing process, the first spring 913 can absorb and disperse part of the energy, thereby reducing the impact on the door body and the surrounding environment, making the door body more stable when closing, and reducing the generation of noise and vibration.

[0028] Further, a rubber pad 8 is fixedly installed at one end of the telescopic rod 7. The rubber pad 8 serves as a buffer layer for the telescopic rod 7 to contact the door body, which can reduce the impact force generated when the door body closes. The elastic property of the rubber can absorb part of the energy, making the door body more gentle when closing, avoiding direct hard impacts, reducing noise and vibration, and at the same time protecting the surface of the door body from being scratched or damaged.

[0029] Further, the outer end of the telescopic plate 5 is arc-shaped. This arc-shaped design makes the outer end of the telescopic plate 5 smoother, reducing the sharpness when contacting the hand or other objects. This design not only improves the safety of use, preventing scratches or pinches caused by sharp corners, but also makes the appearance of the door body more beautiful and harmonious.

[0030] Further, the outer surface of the telescopic plate 5 is wrapped with rubber. The rubber wrapping not only increases the softness and elasticity of the telescopic plate 5, but also improves its wear resistance and corrosion resistance, enabling the telescopic plate 5 to better maintain its shape and performance during long-term use and not being easily deformed or damaged.

[0031] Further, multiple groups of second hinges 4 are used to connect the door frame. The design of multiple groups of second hinges 4 makes the connection between the door body and the door frame more stable and reliable.

[0032] Working principle: First, it is composed of a first door body 1 and a second door body 2, which are flexibly connected by multiple groups of first hinges 3, allowing the smooth folding and unfolding between the door bodies. On one side of the first door body 1, multiple groups of second hinges 4 are additionally installed. These second hinges 4 are mainly used to firmly connect the first door body 1 to the door frame, ensuring the stability and safety of the entire folding door system. During the closing process, installation grooves 6 are specially designed on both sides of one end of the second door body 2. A telescopic plate 5 is installed in the installation groove 6, and the telescopic plate 5 is connected to the installation groove 6 through a second spring 611, enabling the telescopic plate 5 to retract into the installation groove 6 under the action of an external force. When the first door body 1 and the second door body 2 approach and are about to close, the user can assist in controlling the closing speed of the door body by holding the telescopic plate 5. Due to the presence of the telescopic plate 5, even if the door body closes relatively quickly, it is difficult for a person's finger to be caught between the door seams because the telescopic plate 5 will automatically adjust its position under the action of an external force to maintain a safe distance from the finger. In addition, annular through grooves 9 are opened on the outer surfaces of the upper and lower ends of the second door body 2, and a buffer mechanism is provided therein. The buffer mechanism is composed of a circular plate 911, a damper 912, a telescopic rod 7, and a first spring 913. When the first door body 1 and the second door body 2 are about to merge, the telescopic rod 7 will slowly move under the resistance of the damper 912, and at the same time, the first spring 913 will also play a buffering role to reduce the impact force when the door bodies merge. A rubber pad 8 is fixedly installed at one end of the telescopic rod 7. When the two door bodies are completely closed, the rubber pad 8 will gently abut between the door bodies, providing additional buffer protection to prevent noise and vibration caused by direct collision of the door bodies.
