Technical Field
[0001] The utility model belongs to the field of wooden doors, in particular to a wooden door with a small door. Background Art
[0002] With the development of the times, there are more and more wooden doors with small doors, because wooden doors with small doors are usually equipped with screen designs, which are very useful when it is necessary to keep indoor air circulation while preventing mosquitoes from entering. Especially in spring and autumn, opening the small door moderately can introduce natural wind and improve indoor air quality without having to fully open the main door. If transparent or translucent glass is installed on the small door, more natural light can be introduced into the room while ensuring safety, which is especially suitable for rooms facing less sunlight or spaces at the end of the corridor. Moreover, even if the main door is not opened, residents can observe the situation outside the door through the small door, which provides additional security for judging whether to open the door to receive visitors or respond to emergencies.
[0003] However, most of the small doors nowadays do not have a protective structure. If the small door does not have an appropriate protective mechanism, it is easy for the small door to become a breakthrough for intruders, reducing the overall anti-theft performance and posing a threat to family safety. An open small door may make the indoor situation more easily visible to the outside world, affecting the privacy of the residents, so we hope to design a small door with a protective structure, which can achieve the above advantages and solve the above problems.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figures 1 to 5The utility model provides a technical solution: a wooden door with a small door 200, comprising: a main door body 100, a small door 200 arranged on the main door body 100, a through hole is opened through the front and rear surfaces of the main door body 100, and the small door 200 is installed in the through hole;
[0029] The small door 200 includes an inner frame 210, a small door body 220 connected to one side of the inner frame 210 through a hinge 221, the small door body 220 extends outwardly away from the hinge 221 to form an extension portion 223, the inner frame 210 is installed in the through hole, the surface of the inner frame 210 is recessed inwardly to form a groove 211, and the groove 211 is movably connected to the extension portion 223 through a locking structure;
[0030] A protection structure 300 is arranged on the outer side of the main door body 100 .
[0031] As an embodiment of the present invention, the locking structure is composed of a first magnet 212 and a second magnet 224 . The first magnet 212 is fixed on the surface of the groove 211 , and the second magnet 224 is fixed on a side surface of the extension portion 223 and cooperates with the first magnet 212 .
[0032] During actual use, the small door body 220 rotates around the hinge 221. When the extension portion 223 enters the groove 211, the first magnet 212 and the second magnet 224 are attracted together to fix the position of the small door body 220. This fixation is a movable fixation, which is convenient for opening or closing.
[0033] As an embodiment of the present invention, the locking structure is a push-type self-locking switch, which is composed of a self-locking device installed inside the groove 211 and a self-locking head cooperating with the self-locking device. The self-locking head is installed on one side surface of the extension portion 223.
[0034] During actual use, the small door body 220 rotates around the hinge 221. When the extension part 223 enters the groove 211, the self-locking head is locked in the self-locking device and is unlocked by pressing again. This fixing method has higher anti-theft performance. When the self-locking switch is locked, pushing the small door body 220 from the outside will not open the small door body 220.
[0035] As an embodiment of the present invention, a handle 222 is provided on the surface of the small door body 220. By providing the handle 222, it is convenient to pull and rotate the small door body 220.
[0036] The protective structure 300 is composed of four groups of reinforcing ribs 310 , and the four groups of reinforcing ribs 310 are arranged vertically and crosswise on the outer side of the main door body 100 .
[0037] The two sides of the reinforcing rib 310 are bent outward to form two bent portions 320. A limit head 340 is arranged at the bottom of the bent portion 320. The limit head 340 is a hemispherical structure.
[0038] The main door body 100 is provided with a limiting ball 350 cooperating with the limiting head 340 and a cavity for accommodating the limiting ball 350. The cavity is a T-shaped structure, and the cavity extends outward to the surface of the main door body 100. The cross section of the limiting ball 350 is semicircular.
[0039] There are multiple limiting balls 350 and cavities for accommodating the limiting balls 350 . The upper surface of the limiting ball 350 is recessed downward to form a limiting cavity. A circle of limiting rings 351 is arranged on the inner surface of the limiting cavity. The limiting ball 350 has notches 352 on the front and rear sides.
[0040] During installation, after the main frame and the small door body 220 inside the main frame are installed, the bent portions 320 on both sides of a reinforcing rib 310 are aligned with the two limiting balls 350 and inserted (because the cavity extends outward to the surface of the main door body 100, it can be inserted into the limiting ball 350 through the cavity). When the bent portion 320 is inserted into the limiting ball 350, it will first knock down the limiting ring 351, thereby squeezing the limiting ring 351 (because the limiting head 340 is a hemispherical structure, the surface of the arc can slowly squeeze the limiting ring 351), so that the two sides of the limiting ball 350 are opened outward (because of the existence of the notch 352, the two sides of the limiting ball 350 can be opened outward), until the limiting head 340 completely enters the limiting cavity. At this time, the force of the limiting head 340 on the limiting ring 351 disappears, and the two sides of the limiting ball 350 are closed inward, fixing the limiting head 340 in the limiting cavity.
[0041] Because the limit head 340 is a hemispherical structure, if you want to pull out the limit head 340, when pulling out the limit head 340, the flat surface of the limit head 340 contacts the bottom surface of the limit ring 351. At this time, the two sides of the limit ball 350 cannot be opened outward. This design makes it impossible to remove the reinforcement rib 310 after it is fixed, thereby achieving the protection effect of the small door body 220.
[0042] As an embodiment of the utility model, a decorative cover plate 330 is mounted on the bending portion 320. The cover plate 330 can cover the existence of the cavity when the limiting head 340 is inserted into the limiting ball 350, thereby achieving an aesthetic effect.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
