Description

Technical Field

[0001] The utility model belongs to the technical field of wooden doors and relates to a wooden door with stable opening. Background Technique

[0002] Indoor wooden doors, as an indispensable part of home decoration, are highly concerned for their aesthetics, durability and practicality. It is not only a partition between the indoor and outdoor spaces of the house, but also an important carrier to show the taste and style of the homeowner. There are various choices in terms of materials for indoor wooden doors. Common materials include solid wood, solid wood composite, molded doors, etc. Solid wood doors are loved by consumers for their natural texture and warm quality, but the price is relatively high. Solid wood composite doors combine the advantages of solid wood and artificial boards, retaining both the beauty of solid wood and improving the stability of the door. When the wooden door is opened, if its hinge shaft cannot give the wooden door stable rotation, a series of problems may occur. These problems not only affect the use experience of the wooden door, but may also damage the safety and service life of the wooden door.

[0003] If the hinge shaft of the wooden door is unstable during opening, it will cause the shaking and swinging of the door leaf. This kind of shaking will not only generate noise and bring inconvenience to people's daily life, but may also damage the door leaf itself, such as deformation caused by scratches or collisions. The unstable hinge shaft will also affect the sealing performance of the wooden door. If the door leaf cannot fit tightly against the door frame when closed, it will cause too large a door gap, affecting the sound insulation and heat preservation performance of the room. At the same time, too large a door gap may also allow dust and insects to enter the room, affecting the hygiene of the indoor environment. Therefore, there is an urgent need for a wooden door with stable opening to solve the above problems. Content of the Utility Model

The internal structures of the main door body 120 and the sub-door body 130 are the same. An internal fireproof layer 150 for fire protection of the main door body 120 is provided inside the main door body 120. The cross-section of the internal fireproof layer 150 is a square-shaped structure, and the use of the internal fireproof layer 150 can prevent the spread of fire in the case of a fire for the main door body 120 and the sub-door body 130.

[0028] A group of door panels 160 for enhancing the strength of the main door body 120 and the sub-door body 130 are provided inside the internal fireproof layer 150. A set of fitting edges for fitting with the sub-door body 130 are provided at the rear side of the right end of the main door body 120.

[0029] A set of fitting edges for fitting with the main door body 120 are also provided at the front side of the left end of the sub-door body 130. A first anti-collision rubber layer 170 for fitting with the sub-door body 130 is provided inside the fitting edge of the main door body 120.

[0030] A group of threshold seats for bolt-limiting their positions are provided at the lower ends of both the main door body 120 and the sub-door body 130. Embedded holes for bolt-fixing the main door body 120 and the sub-door body 130 are provided inside the threshold seats. The cross-sectional length of the main door body 120 is three times the length of the sub-door body 130.

[0031] The hinge shaft 140 includes a fixed seat 14a and a fixed base 14i, and the fixed seat 14a is fixedly connected to the door frame 100 by bolts;

[0032] Inside the left side of the fixed seat 14a, there is a set of inner rotation shafts 14b for rotatably connecting with a set of movable seats 14e. On the outer side of the inner rotation shafts 14b, there is a set of movable seats 14e for connecting with the mother door body 120. At the front and rear ends on the right side of the movable seat 14e, there is a set of limit fixed shafts 14c for restricting the rotation position of the mother door body 120, and the limit top shaft can be used to keep the mother door body 120 and the child door body 130 stable when opening and closing.

[0033] On the outer side of the limit fixed shaft 14c, there is a set of sliding grooves 14d for limiting its movement. On the left side of the middle position of the limit top shaft, there is a set of inner support arms 14f for supporting the limit ring 14g and the support spring 14h. On the outer side of the left end of the inner support arm 14f, there is a set of grooves for supporting the limit ring 14g;

[0034] Inside the right end of the groove, there is a set of limit rings 14g for limiting the support spring 14h. On the left side of the limit ring 14g, there is a set of support springs 14h for supporting the active pressure of the limit top shaft. On the left side of the support spring 14h, there is a set of fixed bases 14i for limiting the position on the left side of the support spring 14h;

[0035] The inner support arm 14f passes through the inside of the fixed base 14i, and the inside of the groove is mutually fitted. By using the movable seat 14e, it is convenient to rotate the mother door body 120 and the child door body 130 along the inner rotation shaft 14b. At the same time, the rotation paths of the mother door body 120 and the child door body 130 are limited by the limit fixed shaft 14c and the sliding groove 14d. The mother door body 120 and the child door body 130 are automatically retracted and closed by using the support spring 14h and the inner support arm 14f.

[0036] Please refer to Figures 1 - 3, as the first embodiment of the present utility model: To solve the problem that when the hinge shaft 140 is unstable during the opening of a wooden door, it will cause the shaking and swinging of the door leaf. Such shaking will not only generate noise, bringing inconvenience to people's daily life, but also may cause damage to the door leaf itself, such as deformation caused by scratches or collisions. The unstable hinge shaft 140 will also affect the sealing performance of the wooden door. If the door leaf cannot fit tightly against the door frame when closed, it will result in too large a door gap, affecting the indoor sound insulation effect and heat preservation performance. When using the present utility model, since a set of limit rings 14g for limiting the support spring 14h are provided inside the right end of the groove, a set of support springs 14h for supporting the active pressure of the limit top shaft are provided on the left side of the limit ring 14g, and a set of fixed bases 14i for limiting the position on the left side of the support spring 14h are provided on the left side of the support spring 14h. The user connects the movable seat 14e to the mother door body 120 or the sub-door body 130 by bolts. When the mother door body 120 or the sub-door body 130 is opened, its movable seat 14e drives the fixed base 14i to generate a flip, and stores the flipping force of the mother door body 120 and the sub-door body 130 by using the support spring 14h and the inner support arm 14f. When the door body loses the driving force, the support spring 14h restores its deformation and drives the inner support arm 14f to drive the mother door body 120 and the sub-door body 130 to restore their positions.

[0037] Please refer to Figures 1 - 3 , as the second embodiment of the present utility model: Based on the description in the above embodiment, further, since a set of anti-collision rubber layers two 180 for fitting with the mother door body 120 are provided inside the inner fitting edge of the sub-door body 130, both the mother door body 120 and the sub-door body 130 rotate in the clockwise direction, and the opening sequence is the mother door body 120 first and then the sub-door body 130, it is possible to prevent the mother door body 120 and the sub-door body 130 from being deformed and damaged due to collision by using the anti-collision rubber layer one 170 and the anti-collision rubber layer two 180.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
