Description

Technical Field

[0001] The present invention relates to the field of interior decoration, and in particular to a door structure for preventing fingers from being pinched. Background Art

[0002] With the increasing demand for building and home safety, anti-pinch door structures have gradually become an important research direction for door products. Traditional anti-pinch designs mostly rely on mechanical induction or electronic sensors, such as pressure trigger devices or infrared sensing modules. However, these technologies have problems such as high cost, complex structure, and susceptibility to environmental interference. For example, mechanical devices are prone to loss of sensitivity due to long-term squeezing, and electronic sensors may misjudge or fail in humid or dusty environments, affecting user experience and safety. In addition, the application of airflow control methods in the field of door anti-pinch in existing technologies is still immature, especially in how to achieve rapid anti-pinch through dynamic airflow response. There is a technical gap.

[0003] When opening and closing doors, fingers are often pinched. When opening the door, children may be hit because they are too close to the door. Children are relatively short and parents cannot see them when opening and closing the door, which can easily lead to danger. When closing the door, if the hand is in the gap of the door, it is not easy to see and the hand can be easily pinched, which is very painful. How can we prevent fingers from being pinched when opening and closing the door? It is urgent to design an anti-pinch door structure to solve the problem of anti-pinch door structure. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a door structure that prevents hand pinching.

[0005] The present invention is achieved through the following technical solutions: A door structure for preventing finger pinching comprises a first door frame, a second door frame and a door, wherein the first door frame, the second door frame and the door constitute the entire door structure, a first ventilation pipe is fixedly installed on the right side of the first door frame, a first through hole is obliquely opened inside the first ventilation pipe, a first through hole is fixedly installed on the top side of the first ventilation pipe, a fan is installed at the lower right corner of the door, a positioning frame is fixedly installed between the fan and the door, a second air duct is installed on the fan, a second ventilation pipe is fixedly installed on the left side of the door, second through holes arranged obliquely are evenly arranged inside the second ventilation pipe, a connecting pipe is connected between the second ventilation pipe and the second air duct, a handle is installed on the door, and a guide rail is installed at the corresponding position of the handle, a slider corresponding to the guide rail is installed on the handle, and a pressure switch is installed on the handle.

[0006] Preferably, the first through hole and the second through hole are both arranged obliquely, the first ventilation pipe is communicated with the first air guide pipe, and the second ventilation pipe is communicated with the second air guide pipe through a connecting pipe.

[0007] Preferably, the port positions of the first air duct and the second air duct correspond to each other.

[0008] Preferably, the slider slides in cooperation with the guide rail, the guide rail is an arc-shaped frame, a copper sheet is provided at the lower third of the guide rail, a copper block corresponding to the copper sheet is mounted on the slider, the copper sheet and the copper block are connected to the control switch of the fan to control the fan to blow air, and the pressure switch controls the fan to inhale air.

[0009] Preferably, the connecting pipe is a rubber hose.

[0010] Preferably, the fan is a silent fan, which is a blower that can blow and exhaust air.

[0011] Preferably, the first ventilation pipe and the second ventilation pipe are both made of rubber material.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention is configured such that the rubber material can be deformed by setting the first vent tube and the second vent tube, thereby not affecting the closing of the door and also playing a sealing role. The through hole on the vent tube can guide the airflow. By controlling the fan and utilizing the blowing and exhausting of the fan, protection can be provided when opening and closing the door. When opening the door, air is blown outwards, thereby preventing children from getting too close to the door and colliding with it. When closing the door, exhaust is performed. If the hand is in the door gap, suction is generated by exhausting the air, guiding the entire arm to be inserted between the door and the door frame, so that it is more obvious to the person closing the door. The rubber vent tube protects the hand, so even if the hand is pinched, it has no effect, thus preventing the door gap from directly pinching the finger, thus playing a protective role. The airflow is controlled by diversion, thereby preventing the hand from being pinched. The present invention prevents the hand from being pinched when opening and closing the door by controlling the exhausting and blowing of the fan, so that the door structure plays a protective role.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 , the present invention provides a technical solution: A door body structure for preventing finger pinching comprises a first door frame 4, a second door frame 7 and a door 6. The first door frame 4, the second door frame 7 and the door 6 constitute the entire door body structure, a first ventilation pipe 2 is fixedly installed on the right side of the first door frame 4, a first through hole 1 is obliquely opened inside the first ventilation pipe 2, a first air duct 3 is fixedly installed on the top side of the first ventilation pipe 2, a fan 12 is installed at the lower right corner of the door 6, a positioning frame 13 is fixedly assembled between the fan 12 and the door 6, a second air duct 5 is installed on the fan 12, a second ventilation pipe 15 is fixedly installed on the left side of the door 6, second through holes 16 arranged obliquely are evenly arranged in the second ventilation pipe 15, a connecting pipe 14 is connected between the second ventilation pipe 15 and the second air duct 5, a handle 10 is installed on the door 6, and a guide rail 11 is installed at the corresponding position of the handle 10, a slider 9 corresponding to the guide rail 11 is installed on the handle 10, and a pressure switch 8 is installed on the handle 10.

[0019] The first through hole 1 and the second through hole 16 are both arranged at an angle. The first ventilation pipe 2 is connected to the first air guide pipe 3. The second ventilation pipe 15 is connected to the second air guide pipe 5 through the connecting pipe 14. The inclined through holes facilitate the inclined flow of the airflow when the airflow is conducted, and protection is achieved by utilizing the push of the airflow.

[0020] The port positions of the first air duct 3 and the second air duct 5 correspond to each other. Through the corresponding port positions, the first air duct 3 and the second air duct 5 can communicate with each other.

[0021] The slider 9 slides in cooperation with the guide rail 11. The guide rail 11 is an arc-shaped frame. A copper sheet is provided at the lower third of the guide rail 11. The slider 9 is provided with a copper block corresponding to the copper sheet. The copper sheet and the copper block are connected to the control switch of the fan 12 to control the fan 12 to blow air. The pressing switch 8 controls the fan 12 to inhale air. By setting the two groups of control switches, the inflation and deflation of the fan 12 can be controlled.

[0022] The connecting pipe 14 is a rubber hose.

[0023] The fan 12 is a silent fan, which is a blower that can blow and exhaust air. The silent fan greatly reduces noise.

[0024] The first ventilation pipe 2 and the second ventilation pipe 15 are both made of rubber material, which plays a protective role, does not affect the opening and closing of the door, and can further seal the door gap.

[0025] Working principle: The gap between the door and the door frame is relatively large as shown in the figure, but it is not actually that large. The gap is enlarged to show the relationship between the parts. Figure 1 The back is shown in the figure. Figure 3 The front is shown. The copper block on the slider 9 and the copper sheet in the guide rail 11 form the control switch of the fan 12. At the same time, the pressure switch 8 is also the control switch of the fan 12. The control switch composed of the copper sheet and the copper block controls the fan 12 to blow air, and the pressure switch 8 controls the fan 12 to exhaust air. When opening the door, the handle is slid downward, and the handle rotates along the guide rail 11. The sliding of the slider 9 in the guide rail 11 guides it. At this time, the copper sheet and the copper block come into contact, controlling the fan 12 to blow air. At this time, air is blown out through the first through hole 1 and the second through hole 16. The wind force can alert people near the door to prevent them from approaching. When closing the door, the pressure switch 8 is pressed, controlling the fan 12 to exhaust air, and an air flow channel is generated to flow between the door and the door frame, sucking the entire arm between the door and the door frame to prevent fingers from being pinched. Because when the arm is in the door gap, the door cannot be closed directly. Moreover, it is easy to see when closing the door. The air flow guidance prevents the door from pinching the hand.

[0026] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
