[0030] 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 in 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.

[0031] The purpose of the utility model is to provide a core panel unit of a wooden door leaf and a door leaf structure thereof, so as to solve the problems existing in the above-mentioned prior art. There is no need to use a whole board of wood as a basic material, and the production cost is lower. In addition, the basic structure of the core panel unit of the utility model is more solid.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figures 1 to 3 As shown, this embodiment provides a core plate unit of a wooden door leaf, comprising a plurality of core strips arranged in sequence along the height direction of the door leaf, with two adjacent core strips connected, and preferably the two core strips are crimped together by a crimping process, specifically by a plate pressing machine to press the two core strips;

[0034] The core strip includes a plurality of core blocks 4 arranged in sequence along the width direction of the door leaf. The core blocks 4 can be selected from round logs remaining after planing or other wood remaining after wood processing. Two adjacent core blocks 4 are connected. Preferably, the two core blocks 4 are crimped together by a crimping process, and specifically, a plate pressing machine is used to press the two core blocks 4. Two notches are respectively opened on both sides of the core block 4 along the arrangement direction thereof, and each notch penetrates the core block 4 along the thickness direction of the door leaf. The two notches located on the same side of the core block 4 are distributed on both sides of the core block 4 along the height direction of the door leaf. Between two adjacent core blocks 4 on the same core strip, the corresponding two notches are combined into a semi-closed trough-shaped structure.

[0035] Between two adjacent core strips along the height direction of the door leaf, the corresponding two trough-like structures are combined into a closed through-hole structure 5. Preferably, the radial cross-section of the through-hole structure 5 includes but is not limited to a circle and a diamond. Then, when the door leaf is subsequently manufactured, after the decorative panels are used to cover both sides of the core panel unit, the through-hole structure 5 forms a through hole between the two decorative panels to achieve the purpose of sound insulation and noise reduction, and the structure other than the through-hole structure 5 is used as support.

[0036] The utility model uses round logs remaining after planing or rod-shaped wood remaining after wood processing as the basic raw material, and uses the core block 4 as the basis. The core blocks 4 are crimped together to form core strips, and the core strips are crimped together to form the basic structure of the core board unit. The material selection of the entire core board unit is relatively convenient, and there is no need to use the whole board of wood as the basic material, and the production cost is lower. Moreover, the core blocks 4 and core strips are crimped into an integral structure, which serves as the basic frame of the door leaf. Compared with the prior art that uses wood chips as filling, the basic structure of the core board unit of the utility model is more solid. Furthermore, by opening a notch in the core block 4, a through-hole structure 5 can be directly formed in the process of splicing the core block 4 and its core strip, so as to achieve a better sound insulation effect for the door leaf that is subsequently manufactured, and avoid opening holes after splicing the core block 4 and the core strip, which affects the solidity of the overall structure.

[0037] As a preferred embodiment of the utility model, the two end faces of the core block 4 along the thickness direction of the door leaf are cross-sections of the wood, and the side faces of the core block 4 between the two end faces are radial sections of the wood. The end faces of the core block 4 are cross-sections of the wood, which makes the end face structure of the core block 4 more stable. When the door leaf is manufactured, it is supported on the inner wall of the door leaf facing to ensure that the door leaf is not easily deformed during long-term use, thereby extending its service life.

[0038] Furthermore, in order to ensure that two adjacent core strips can be effectively positioned when spliced ​​and avoid misalignment, the core strip is provided with multiple groups of positioning grooves 7 and positioning protrusions 6 corresponding to each core block 4. The positioning grooves 7 and positioning protrusions 6 in each group are distributed on both sides of the core block 4 along the height direction of the door leaf, and each positioning groove 7 and each positioning protrusion 6 are respectively arranged on the same side, and the corresponding positioning grooves 7 and positioning protrusions 6 between two adjacent core strips are embedded. Then, before crimping each core strip, each core strip is positioned by the positioning grooves 7 and positioning protrusions 6 to ensure the stability of the position of each core strip, thereby improving the crimping quality of the core strip.

[0039] Preferably, the positioning groove 7 and the positioning protrusion 6 are both strip-shaped structures, extending along the thickness direction of the door leaf, and matching the thickness of the core block 4. By defining the structure of the positioning groove 7 and the positioning protrusion 6, it is ensured that the connection between the two core strips can be more stable after the two are engaged. It is also preferred that the positioning groove 7 and the positioning protrusion 6 are respectively located between the two notches distributed along the width direction of the door leaf, and located in the middle of the core block 4, so as to ensure that the core blocks 4 of the upper and lower core strips correspond to each other, thereby ensuring the crimping strength.

[0040] A door leaf structure is also provided, comprising a door leaf structure body and an annular support frame 2, wherein the door leaf structure body comprises a plurality of vertical units 1 arranged in sequence along the width direction of the door leaf, the vertical unit 1 is provided with a plurality of core plate units arranged in sequence along the height direction of the door leaf, a first sealing plate 3 is crimped between two adjacent vertical units 1, and each vertical unit 1 is connected and reinforced by the first sealing plate 3, thereby avoiding that the entire door leaf structure body is made by crimping core strips, which easily causes insufficient strength of the entire door leaf structure body, the width of each first sealing plate 3 along the height and thickness direction of the door leaf is matched with each vertical unit 1, so as to be able to cover the side wall of the entire vertical unit 1 along the thickness direction of the door leaf, and the annular support frame 2 is arranged around the outer peripheral side of the door leaf structure body to serve as the structural frame of the door leaf structure body, thereby performing annular support on the door leaf structure body composed of each vertical unit 1, thereby improving the strength of the entire door leaf structure;

[0041] Specifically, the width of each vertical unit 1 after being combined with the first sealing plate 3 matches the width of the manufactured door leaf, and the height of the vertical unit 1 matches the height of the prepared door leaf. Subsequently, the door leaf finishing is directly covered on the outer peripheral side of the entire door leaf structure body and the annular support frame 2 to complete the manufacture of the door leaf.

[0042] In order to further ensure the structural strength of the door leaf structure, a second sealing plate is crimped between two adjacent core panel units in the same vertical unit 1, that is, the two adjacent core panel units are connected by the second sealing plate, so that the core panel unit and the second sealing plate are combined into an integrated structure, thereby avoiding the entire vertical unit 1 being made of core panel units crimped together, which easily causes the structural strength of the entire vertical unit 1 to be weakened.

[0043] Furthermore, a method for manufacturing a door leaf structure is provided, comprising the following steps:

[0044] S1. Select multiple wooden strips of equal length. The preferred wooden strips can be round logs left after planing or other wood left after wood processing. Each wooden strip extends along the growth direction of the wood. Each wooden strip is planed on four sides and the width and thickness are set to the required size; so that each wooden strip is made into an equal structure, which is convenient for subsequent splicing processing;

[0045] S2, after gluing, the wood strips are put into the panelizing machine, and are spliced ​​and pressed into panelizing units, so as to facilitate the subsequent positioning processing and the splicing of each panelizing unit, and avoid the wood strip structure being too thin, which is inconvenient for the subsequent pressing work; it should be noted that the panelizing unit is a plate-like structure spliced ​​by wood strips as a whole. If a core strip needs to be prepared, the panelizing unit is directly cut to obtain a core strip of corresponding thickness;

[0046] S3, planing each panel unit on four sides, and processing the notch, positioning groove 7 and positioning protrusion 6;

[0047] S4, arranging the panel units together and performing secondary pressing to form a panel unit structure;

[0048] S5. According to the required thickness of the door leaf, sawing is performed along the panel unit structure in a direction perpendicular to the extension of the wood strips to obtain a plurality of core panel units;

[0049] S6, pressing the first closing plate 3 on both sides of the core plate unit perpendicular to the extension direction of the wood strips, and combining them into a vertical unit 1; specifically according to the width of the manufactured door leaf and the width of the first closing plate 3 corresponding to it, the core plate unit is cut into corresponding lengths, and then the required height of the vertical unit 1 can be directly obtained after the combination, avoiding subsequent cutting, etc.;

[0050] S7. According to the required width of the door leaf, the vertical units 1 are spliced ​​together to form the door leaf structure body, and the corresponding annular support frame 2 is selected and installed around the outer peripheral side of the door leaf structure body. The specific annular support frame 2 is composed of four support plates, and each support plate is respectively attached and installed on the two side surfaces and the top surface of the door leaf structure body to form an annular structure.

[0051] Adaptive changes made according to actual needs are all within the protection scope of this utility model.

[0052] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numerals in the claims should not be regarded as limiting the claims involved.

[0053] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
