Description

Technical Field

[0001] The utility model belongs to the technical field of paint-free doors, in particular to a paint-free door with thermal insulation effects. Background Art

[0002] As the name suggests, paint-free doors are wooden doors that do not need to be painted. Most of the paint-free doors on the market refer to PVC veneer doors. They are made by vacuum forming the outer surface of solid wood composite doors or molded doors with PVC veneer. The door cover is also treated with PVC veneer. Another type of finished wooden door that has been painted in the factory is also called a paint-free door.

[0003] Regarding the heat preservation and heat insulation of paint-free doors, the existing public patent (publication number CN 207393037 U) discloses a heat-insulating, heat-insulating and sound-proof paint-free door, including a door panel and a handle, a door frame is installed on the outside of the door panel, a mounting plate is installed on the right side of the front of the door panel, the handle is installed in the middle of the mounting plate, a sound-absorbing cotton layer is pasted on the front of the door panel, and a honeycomb sound-absorbing bump is fixedly connected to the front of the sound-absorbing cotton layer, and the top and bottom of the inner cavity of the door panel are fixedly connected with an isolation plate. The heat-insulating, heat-insulating and sound-proof paint-free door is provided with a sound-absorbing cotton layer, a honeycomb sound-absorbing bump, a heat-insulating layer, a first vacuum layer and a heat-insulating layer, and the sound-absorbing cotton layer and the honeycomb sound-absorbing bump are used to absorb sound to enhance the sound insulation effect, and the heat-insulating layer and the heat-insulating layer are used to enhance the heat-insulating and heat-proof effects of the door panel respectively, and at the same time, the vacuum environment of the first vacuum layer can be used for heat preservation, heat insulation and sound insulation, thereby enhancing the heat-insulating, heat-insulating and sound-proof effects, and making it more convenient to use.

[0004] Although the structural setting of the paint-free door can improve the thermal insulation and sound insulation effect of the paint-free door, the overall structural setting does not meet the aesthetic requirements of current users, and the overall structure is relatively abrupt. To this end, we provide a paint-free door with thermal insulation effect to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a paint-free door with heat preservation and heat insulation effect, comprising a paint-free door body, a door frame arranged at the edge of the paint-free door body, and a door lock matched with the paint-free door body; the paint-free door body comprises a patch layer, an outer plate arranged at the inner side of the patch layer, a heat preservation and heat insulation board arranged at the inner side of the outer plate, and an inner plate arranged at the inner side of the heat preservation and heat insulation board;

[0007] A plurality of chambers are arranged inside the thermal insulation board, and the chambers are filled with thermal insulation cotton.

[0008] The utility model is further configured that a lock hole for installing a door lock is opened on the edge of the paint-free door body.

[0009] The utility model is further configured that a sealing strip is embedded in the bottom of the thermal insulation board.

[0010] The utility model is further configured that the patch layer, the outer plate thermal insulation board and the inner plate are compounded layer by layer by glue, and the side surface of the inner plate is also compounded with the patch layer.

[0011] The utility model is further configured such that the door frame is connected to the external wall, and a cavity formed between the groove of the door frame and the external wall is filled with thermal insulation cotton.

[0012] The utility model is further configured that a protective rubber strip is provided on the inner edge of the door frame, and the protective rubber strip matches the edge of the paint-free door body.

[0013] The utility model has the following beneficial effects:

[0014] The utility model improves the thermal insulation effect of the paint-free door body without affecting the structural strength of the paint-free door body by compounding a thermal insulation board structure in the paint-free door body. The thermal insulation board is a grid structure, and the interior of each mesh hole is a cavity for filling and installing thermal insulation cotton. When the mesh surface is compounded and fixed with the outer plate and the inner plate, the contact surface is uniform, and the overall structural strength of the subsequent paint-free door body is not affected.

[0015] At the same time, the protective rubber strip structure set on the edge of the door frame has multiple functions, such as: buffering and protecting the opening and closing of the paint-free door body, improving the quiet effect, and assisting in increasing the thermal insulation of the paint-free door body. The thermal insulation cotton filled in the door frame groove is also used for thermal insulation. Under the premise of not affecting the installation stability of the door frame, the thermal insulation effect of the door frame installation is improved. The sealing strip embedded in the bottom of the thermal insulation board is in contact with the ground, which is used to seal the gap between the bottom of the paint-free door body and the ground, thereby improving the thermal insulation effect of the paint-free door body. Through the auxiliary effect of the above structure, the thermal insulation effect of the paint-free door is improved, and the paint-free door body structure is reasonably set, in line with the aesthetic design concept, and is easily accepted by users.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
