[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0026] Reference Figure 1-6 The utility model provides an embodiment: a high-strength composite wooden door, including a door body 1 and a door frame 2, a groove 3 is opened at the lower part of one side of the door body 1, a plurality of springs 5 are fixedly arranged on the inner wall of one side of the groove 3, a bump 4 is fixedly arranged on one end of the plurality of springs 5, a screw 10 is rotatably arranged at the upper part of one side of the door body 1, an inner groove 12 is opened at the lower part of one side of the inside of the door body 1, one end of the screw 10 penetrates through the inner wall of one side of the inner groove 12, a threaded sleeve 9 is threadedly sleeved around the screw 10, a connecting plate 8 is fixedly sleeved around the threaded sleeve 9, a push rod 7 is fixedly arranged at the lower part of one side of the connecting plate 8, one end of the push rod 7 penetrates through the groove 3 and is fixedly arranged with a push plate 6.
[0027] By setting a plurality of springs 5, an outward force can be applied to the protrusion 4 through the tension of the spring 5, so that the door body 1 remains intact. When a child's finger accidentally extends between the door frame 2 and the door body 1, the compression of the spring 5 can cause the protrusion 4 to retract into the groove 3, thereby avoiding pinching the child's finger. By setting a screw 10 and a threaded sleeve 9, the position of the threaded sleeve 9 can be moved by rotating the screw 10 by preventing the threaded sleeve 9 from rotating. The movement of the threaded sleeve 9 can drive the push plate 6 to move to one side to resist the protrusion 4, thereby avoiding the protrusion 4 from opening.
[0028] The door body 1 includes two door panels 101 , a steel plate 102 is disposed between the two door panels 101 , and a plurality of bolts 103 are fixedly disposed at the rear end of the front door panel 101 .
[0029] The structural strength of the door body 1 can be effectively enhanced by providing the steel plate 102, which enables the door to better resist external impact and pressure and improves the durability and safety of the door. A plurality of bolts 103 are provided that pass through the steel plate 102 and another door panel 101 and are connected by nuts 104, so that the connection between the door panel 101 and the steel plate 102 is tighter.
[0030] The door panel 101 includes a base layer 10101, a sound insulation layer 10102 is fixedly provided on one side of the base layer 10101, a flame retardant layer 10103 is fixedly provided on one side of the sound insulation layer 10102, a protective layer 10104 is fixedly provided on one side of the flame retardant layer 10103, the base layer 10101 is set as a medium-density fiberboard, the sound insulation layer 10102 is set as rock wool, the flame retardant layer 10103 is set as a nitrogen-based flame retardant coating, and the protective layer 10104 is set as acrylic coating. A knob 11 is fixedly provided at one end of the screw rod 10, and the knob 11 is embedded in one side of the door body 1. The rear ends of multiple bolts 103 all penetrate the rear door panel 101 and nuts 104 are threadedly sleeved at the rear of the body. The door body 1 and the door frame 2 are hinged by multiple hinges.
[0031] The wooden door adopts medium-density fiberboard, which is a kind of composite wood with multiple advantages such as uniformity, stability, environmental protection and economy. The sound insulation effect of the wooden door can be improved by setting a sound insulation layer 10102, which is set as rock wool. Rock wool has a high sound absorption coefficient, can effectively absorb sound waves, reduce noise, and improve the comfort of the indoor environment. The flame retardant coefficient of the wooden door can be improved by setting a flame retardant layer 10103, which is set as a nitrogen-based flame retardant coating. This type of coating contains nitrogen compounds as the main flame retardant. Nitrogen can react in the gas phase during a fire to form an inert atmosphere to prevent the spread of flames. A protective layer 10104 is set, which is set as acrylic coating, which is a coating with good weather resistance and chemical corrosion resistance. It is commonly used in anti-corrosion coatings on wood surfaces. It can form a tough film layer to provide effective protection. A turning knob 11 is set and embedded in one side of the door body 1, so that the screw 10 can be easily rotated and can also be hidden.
[0032] Working principle: When the wooden door is in use, through the anti-pinch structure, if a child accidentally puts his finger between the door body 1 and the door frame 2, due to the multiple springs 5 connecting the protrusion 4, the protrusion 4 can be squeezed into the groove 3 and then reset and extended, which can prevent the child's finger from being pinched. When not in use, the screw 10 can be rotated to move the threaded sleeve 9 on the screw 10, so that the connecting plate 8 connected to the threaded sleeve 9 moves to one side, driving the push rod 7 to push the push plate 6 so that the push plate 6 blocks the protrusion 4, so that the protrusion 4 cannot be retracted into the groove 3, and the protrusion 4 is fixed. In addition, a steel plate 102 is arranged inside the door body 1 to enhance the strength of the door body 1 and improve the durability and safety of the door.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
