Detailed Description
Referring to fig. 1 to 6, a preferred embodiment of a door structure for preventing hand pinching includes a door frame 10 and a door body 20.
The door frame 10 is provided with a yielding groove 11 longitudinally extending along the door frame 10, and an upper fixing seat 12 and a lower fixing seat 13 are arranged in the yielding groove 11. As shown in fig. 5, the upper fixing base 12 is in a sheet shape and arranged transversely, and is provided with a top protruding shaft 121 extending downwards; the lower fixing base 13 is provided with a bottom end shaft sleeve (not shown in the figure). As shown in fig. 2, the distance between the upper fixing base 12 and the lower fixing base 13 is just the height of the door 20. Spaces can be reserved between the upper fixing seat 12 and the top end face of the doorframe 10 and between the lower fixing seat 13 and the bottom end face of the doorframe 10; or, the upper fixing seat 12 and the top end surface of the door frame 10, and the lower fixing seat 13 and the bottom end surface of the door frame 10 can be close to or in contact with each other, as required.
In this embodiment, as shown in fig. 3, the receding groove 11 includes a first groove wall 111 and a second groove wall 112 that are vertically arranged, the first groove wall 111 is parallel to the length direction of the door 20, the second groove wall 112 is parallel to the width direction of the door 20, and both the upper fixing seat 12 and the lower fixing seat 13 are fixedly connected to the second groove wall 112.
In this embodiment, the door frame 10 is further provided with a limiting step 15 arranged opposite to the receding groove 11, and when the door body 20 is at the closing position, the door body 20 abuts against the limiting step 15.
The door body 20 comprises a body and a semicircular rotating shaft 21 fixedly connected to the side edge of the body, two ends of the semicircular rotating shaft 21 are respectively and rotatably connected with the upper fixing seat 12 and the lower fixing seat 13 so that the door body 20 can rotate between an opening position and a closing position, and the semicircular rotating shaft 21 and the groove wall of the abdicating groove 11 are always in small clearance fit.
In this embodiment, the semicircular rotating shaft 21 includes a semicircular arc surface 211 and a vertical surface 212 connected to each other, the vertical surface 212 intersects with a central axis of the semicircular arc surface 211, and a width of the vertical surface 212 is the same as a thickness of the door body 20. As shown in fig. 7, when the gap between the vertical surface 212 and the door body 20 is small enough, the door body 20 is in an integrated structure in appearance, so that the aesthetic degree of the door structure is greatly improved, and the integrity is stronger; moreover, the semicircular arc surface 211 of the semicircular rotating shaft 21 can complete the rotating function in the rotating process, the whole circular arc surface is not needed, and the size of the door body 20 can be reduced while the rotating function is ensured.
In this embodiment, the vertical surface 212 of the semicircular rotating shaft 21 is provided with a fixing strip 213, and the body is locked and matched with the fixing strip 213 for fixing. As shown in fig. 8, the fixing strips 213 are provided in two and spaced apart arrangement.
In this embodiment, the body includes a first decorative plate 22, a central plate 23, a second decorative plate 24 and a side plate 25, the first decorative plate 22 and the second decorative plate 24 are respectively fixed on the front and back sides of the central plate 23, the fixing strip 213 is sandwiched between the central plate 23 and the first decorative plate 22 or the second decorative plate 24 and is locked on the central plate 23, and the side plate 25 is fixed on the side edge of the central plate 23 and abuts against the side edges of the first decorative plate 22 and the second decorative plate 24.
The installation process of the door body is as follows: firstly, two fixing strips respectively lean against the front and back of the central plate 23 and are locked and matched through screws, so that the semicircular rotating shaft 21 and the central plate 23 are fixed; then, the side plate 25 and the central plate 23 are locked and fixed through screws; and then the first decorative plate 22 and the second decorative plate 24 are respectively stuck on the front and back surfaces of the central plate 23, thus completing the assembly of the body and the semicircular rotating shaft 21. A door lock structure can also be arranged on the body according to requirements.
In this embodiment, the top end and the bottom end of the semicircular rotating shaft 21 are respectively provided with a top end shaft sleeve 214 and a bottom end protruding shaft 215, the top end shaft sleeve 214 is rotatably matched with the top end protruding shaft 121, and the bottom end protruding shaft 215 is rotatably matched with the bottom end shaft sleeve, so as to realize the rotation of the door body 20 relative to the door frame 10.
Because the door body 20 comprises the semicircular rotating shaft 21, and the semicircular rotating shaft 21 is always in small clearance fit with the groove wall of the abdicating groove 11, no matter how the door body 20 rotates, the clearance between the semicircular rotating shaft 21 and the groove wall of the abdicating groove 11 cannot be switched between large and small, and the risk that hands are mistakenly placed in the clearance when the clearance between the two is large and the hand is clamped when the clearance between the two is small can be prevented; moreover, the door structure is beautiful and elegant in appearance, good in integrity and basically the same as a common door structure in appearance.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
