Abstract
Description
Technical Field
[0001] This utility model relates to the field of security door technology, and in particular to a double-slanted security door with anti-pinch function. Background Technology
[0002] Anti-pinch and anti-collision safety doors are specially designed doors primarily to prevent pinching and impact injuries, and are commonly used in public places such as schools, shopping malls, and hospitals. Anti-pinch and anti-collision safety doors typically employ anti-pinch measures on the door panel and frame. The main methods for preventing pinching include: installing doorstops on the door, which act as a buffer when the door closes; installing anti-collision strips, which are soft rubber materials that can be attached to the door panel or frame to cushion the impact when the door closes, reducing the possibility of pinching injuries; and using door clamp protectors, installed on the door clamps, which also act as a buffer when the door closes.
[0003] However, existing technologies still have shortcomings. Existing anti-pinch and anti-collision safety doors only have a simple buffering effect, reducing the possibility of pinching injuries, but cannot deal with situations where the person is already pinched.
[0004] Therefore, we propose a double-slanted safety door with anti-pinch function to solve this problem. Utility Model Content
[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a double-slanted safety door with anti-pinch function.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A double-slanted safety door with anti-pinch function includes a door frame; a hinge is fixedly connected to one outer surface of the door frame; a safety door body is fixedly connected to one end of the hinge; a door handle is fixedly connected to the front surface of the safety door body; a first sliding groove is provided on one outer surface of the safety door body; a buffer block is slidably installed on the inner surface of the first sliding groove; a first spring is fixedly connected to one outer surface of the buffer block; a second sliding groove is provided on the other outer surface of the safety door body; a first guide hole is provided on the inner surface of the second sliding groove; a second guide hole is provided on one side of the inner surface of the first guide hole; a connecting block is slidably installed on the inner surface of the second sliding groove; a connecting rod is rotatably installed on the inner surface of the connecting block; an anti-pinch wheel is fixedly connected to the outer surface of the connecting rod; a guide rod is fixedly connected to one outer surface of the connecting block; a guide block is fixedly connected to one end of the guide rod; a second spring is sleeved on the outer surface of the guide rod.
[0008] Preferably, one end of the first spring is fixedly connected to the inner surface of the first groove; the guide rod is slidably installed on the inner surface of the first guide hole.
[0009] Preferably, one end of the second spring is fixed to the outer surface of the connecting block; the other end of the second spring is fixed to the inner surface of the second sliding groove.
[0010] Preferably, the guide block is slidably mounted on the inner surface of the second guide hole; one end of the buffer block is a hemispherical block.
[0011] In this utility model, a double-sloping safety door with anti-pinch function is provided. Through the arrangement of the door frame, hinge, safety door body, door handle, second slide groove, first guide hole, second guide hole, connecting block, connecting rod, anti-pinch wheel, guide rod, second spring, and guide block, when the safety door body is closed, if a finger is pinched, the finger will squeeze the connecting block into the second slide groove. The movement of the connecting block will compress the second spring, and the anti-pinch wheel will assist the movement of the connecting block, making it easier for the connecting block to be squeezed into the second slide groove by the finger. It can also prevent the skin on the finger from being scratched by the connecting block, thus preventing the finger from being pinched when the door is closed and improving safety.
[0012] In this utility model, a double-sloping safety door with anti-pinch function is provided. Through the setting of a first sliding groove, a buffer block, and a first spring, when the safety door body is closed, the safety door body will squeeze the buffer block. The movement of the buffer block will compress the first spring, thereby reducing the speed at which the safety door body closes, giving people time to react, and reducing the probability of hand pinching.
[0013] This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description

[0023] In this invention, when the safety door body 3 is closed, if a finger is pinched, the finger will press the connecting block 11 into the second slide groove 8. The movement of the connecting block 11 will compress the second spring 15. The anti-pinch wheel 13 will assist the movement of the connecting block 11, making it easier for the connecting block 11 to be pressed into the second slide groove 8 by the finger. It can also prevent the skin on the finger from being scratched by the connecting block 11, thus preventing the finger from being pinched when the door is closed and improving safety. When the safety door body 3 is closed, the safety door body 3 will press the buffer block 6. The movement of the buffer block 6 will compress the first spring 7, thereby reducing the speed at which the safety door body 3 closes, giving people time to react and reducing the probability of fingers being pinched.
