Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of KFC doors, in particular to a KFC door with a hand-pinching prevention function. Background Art
[0002] KFC doors, an industry term, are primarily suitable for installation on both interior and exterior doors in venues such as hotels, shopping malls, office buildings, banks, cafes, showrooms, and fast food restaurants. They effectively insulate against heat, dust, sand, noise, and other obstacles, as well as provide a shield. However, finger pinching incidents with KFC doors are common in real life. Therefore, a KFC door with a hand-prevention function is needed to address this need. Utility Model Content
[0003] In view of the above technical problems, the utility model provides a KFC door with an anti-hand pinching function.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a KFC door with an anti-finger pinching function, comprising a door frame, wherein glass is inlaid in the door frame, and the side that is connected when the door frame is closed is an inner frame, and a groove is provided at the lower part of the inner frame, and a rotating block is rotatably connected in the groove, and the upper and lower ends of the rotating block are fixedly connected to a rotating shaft, and a fixing hole is provided on the back, and a torsion spring is fixedly connected to the rotating shaft, and the two ends of the torsion spring are in contact with the inner wall of the inner frame, and a safety hole is provided above the inner frame, and a safety rod is slidably connected in the safety hole, and a fixing rod is rotatably connected inside the inner frame, and the top of the fixing rod is connected to the safety rod, and the bottom is connected to a fixing plate, and the fixing plate matches the fixing hole.
[0005] Furthermore, a door closer is provided on the top of the door frame.
[0006] Furthermore, a handle is fixedly connected to the side of the door frame.
[0007] Compared with the prior art, the present invention has the following advantages:
[0008] The present invention is provided with a rotating block and uses a torsion spring to control the rotating block. When the door is closed, the rotating block can be reset and aligned, thereby improving the airtightness to a certain extent and also serving as a windbreak. When a child bends the rotating block to rotate, the rotating block will not cause a hand pinching incident due to its rotating nature. When locking the door, the safety bar is moved and the fixed block is inserted into the fixed hole using the fixed rod to limit the rotation of the rotating block and prevent a gap from being generated when locking the door. If the rotating block is forgotten to be opened and a hand pinching incident occurs, the safety bar can be opened to still remove the child's hand through the rotating block. The safety bar is set above the inner frame to prevent children from bending it. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figure 1-Figure 5 The KFC door with anti-finger pinching function shown in the figure includes a door frame 1, the door frame 1 is inlaid with glass, and the side connected when the door frame 1 is closed is an inner frame 2. A groove is provided at the lower part of the inner frame 2, and a rotating block 3 is rotatably connected in the groove. The upper and lower ends of the rotating block 3 are fixedly connected to a rotating shaft 8, and a fixing hole 9 is provided on the back. A torsion spring 10 is fixedly connected to the rotating shaft 8, and both ends of the torsion spring 10 abut against the inner wall of the inner frame 2. A safety hole 5 is provided above the inner frame 2, and a safety rod 7 is slidably connected in the safety hole 5. A fixing rod 11 is rotatably connected inside the inner frame 2, and the top of the fixing rod 11 is connected to the safety rod 7, and the bottom is connected to a fixing plate 12, and the fixing plate 12 matches the fixing hole 9.
[0017] It should be noted that, in this embodiment, a slideway is provided inside the inner frame 2 which is consistent with the moving track of the fixing piece 12 .
[0018] In order to realize automatic door closing, a door closer 6 is provided on the top of the door frame 1 .
[0019] In order to facilitate opening the door, a handle 4 is fixedly connected to the side of the door frame 1.
[0020] The specific working process of this utility model is as follows:
[0021] When a child plays near the door, due to his height, he will grab the lower part of the door frame 1 to open and close the door. The lower part of the inner frame 2 is the rotating block 3. If the child accidentally grabs the rotating block to close the door, the rotating block 3 will not pinch the child's hand. The torsion spring 10 allows the rotating block 3 to return to its original position when there is no force on it.
[0022] When closing the door, the safety lever 5 is pulled, the fixing rod 11 rotates, and the fixing plate 12 is driven to move and insert into the fixing hole 9. After the door is closed, the rotating block 3 will not be rotated. If the safety lever 5 is forgotten to be withdrawn and a child's hand is pinched, the safety lever 5 can be opened first, and then the rotating block 3 can be rotated in different directions to expand the gap and release the child.
