Description

Technical Field

[0001] This utility model relates to the field of wooden door production technology, specifically an impact-resistant solid wood composite door structure. Background Technology

[0002] Solid wood composite doors typically have a core made of pine, fir, or imported filling materials bonded together, with MDF and solid wood veneer applied to the outside. They are manufactured through high-temperature hot pressing and edged with solid wood strips. The door leaf uses a frame of fir engineered wood, requiring sanding to a certain thickness before pressing a 3mm thick MDF board, followed by sanding again and hot pressing to apply a thin veneer. This process corrects the unevenness of the substrate in the original process, which caused ripples on the surface after the veneer was applied. The core panel is milled on all four sides. Currently, existing solid wood composite doors use a single panel as the main structure, making them susceptible to damage from strong impacts. Damage requires replacement of all parts, resulting in high repair costs and poor impact resistance. Utility Model Content

[0003] The purpose of this invention is to provide an impact-resistant solid wood composite door structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An impact-resistant solid wood composite door structure includes an upper crossbeam, a lower crossbeam, and two parallel longitudinal frames. The upper crossbeam is installed at the top of the two longitudinal frames, and the lower crossbeam is installed at the bottom of the two longitudinal frames. A hinge that can be connected to the door frame is installed on the side of one longitudinal frame, and a door lock is installed on the other longitudinal frame. Multiple sashes that can be spliced ​​together are provided between the upper and lower crossbeams.

[0006] The inside of the fan panel is provided with a door core, the outside of the door core is provided with a density board, and the outside of the density board is provided with a solid wood veneer.

[0007] The end of the fan plate is provided with a spindle-shaped reinforcing component, and the inner sides of the two adjacent longitudinal frames are provided with mounting grooves, which can be connected to the end of the reinforcing component.

[0008] Furthermore, the top of the fan plate is provided with an embedding groove capable of accommodating the reinforcing component, the top of the fan plate is fixed inside the embedding groove with a second plug-in component, and the bottom of the fan plate is provided with a second plug-in groove.

[0009] Preferably, the outer side of the second connector is movably fitted with a buffer sleeve, and both the second connector and the buffer sleeve have a spindle-shaped structure.

[0010] Furthermore, the reinforcing component includes:

[0011] The first reinforcing back rib has mounting holes at its ends;

[0012] The second reinforcing back rib is installed and fixed on one side of the first reinforcing back rib. The first and second reinforcing back ribs can be fixed by riveting.

[0013] Preferably, the end of the first reinforcing back rib is an L-shaped structure. When the first reinforcing back rib with an L-shaped end is installed, its end is placed inside the mounting groove. The L-shaped end makes it easy to install the first reinforcing back rib on the mounting groove. The middle part of the first reinforcing back rib and the middle part of the second reinforcing back rib are both arc-shaped structures. The combination of the first reinforcing back rib and the second reinforcing back rib can be arranged inside the embedding groove.

[0014] Preferably, a first connector is fixed to the top of the lower crossbeam.

[0015] Preferably, the bottom of the upper crossbeam is provided with a first insertion groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting multiple panels and reinforcing components, the panels can be spliced ​​together to form a whole. This splicing method allows for easy repair after some panels are damaged by strong impacts; the original panels can be replaced directly without replacing the entire composite door structure, thus reducing maintenance costs. The reinforcing components improve the strength of the connection between the panels and the frame, and also cushion impacts, enhancing the overall impact resistance.

[0018] 2. When the fan plate is impacted, the first or second reinforcing back rib in the reinforcing assembly absorbs the impact force, thereby reducing the distance between the first and second reinforcing back ribs. This causes the ends of the first and second reinforcing back ribs to tend to move away from each other, making the end of the first reinforcing back rib fit tightly against the mounting groove. This reduces the possibility of the fan plate detaching due to impact and effectively offsets the impact on both sides of the fan plate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-8 In this embodiment of the utility model, an impact-resistant solid wood composite door structure includes an upper horizontal beam 20, a lower horizontal beam 30, and two parallel longitudinal frames 10. The upper horizontal beam 20 is installed on the top of the two longitudinal frames 10, and the lower horizontal beam 30 is installed on the bottom of the two longitudinal frames 10. A hinge that can be connected to the door frame is installed on the side of one longitudinal frame 10, and a door lock 60 is installed on the other longitudinal frame 10. Multiple sash panels 40 that can be spliced ​​together are provided between the upper horizontal beam 20 and the lower horizontal beam 30.

[0029] In this embodiment, the interior of the sash panel 40 is provided with a door core 45, the exterior of the door core 45 is provided with a density board 46, and the exterior of the density board 46 is provided with a solid wood veneer 47. The top of the sash panel 40 is provided with an embedding groove 41 that can accommodate the reinforcing component 50. The top of the sash panel 40 is fixed inside the embedding groove 41 and a second plug-in member 42 is fixed inside the top of the sash panel 40. The bottom of the sash panel 40 is provided with a second plug-in groove 44. When multiple sash panels 40 are spliced ​​together, the end of the second plug-in member 42 can be inserted into the inside of the second plug-in groove 44 on an adjacent sash panel 40, so that multiple sash panels 40 can be formed into a whole. Furthermore, the splicing and installation method of the sash panels 40 allows for repair by directly replacing the original sash panel 40 after some sash panels 40 are damaged by strong impact, without the need to replace the entire composite door structure, thus reducing repair costs.

[0030] In this embodiment, the end of the fan plate 40 is provided with a spindle-shaped reinforcing component 50. Mounting grooves 11 are provided on the adjacent inner surfaces of the two longitudinal frames 10, and the mounting grooves 11 can connect to the end of the reinforcing component 50. The reinforcing component 50 includes a first reinforcing back rib 51 with mounting holes at its end and a second reinforcing back rib 52 fixed to one side of the first reinforcing back rib 51. The first reinforcing back rib 51 and the second reinforcing back rib 52 have an arc-shaped structure and can be fixed by riveting. The first reinforcing back rib 51 and the second reinforcing back rib 52 also form a spindle-shaped structure. For example, when the second reinforcing back rib 52 is subjected to such... Figure 4 Upon impact in direction A, the impact force pushes the middle part of the second reinforcing back rib 52 towards the first reinforcing back rib 51, thereby causing the ends of the first reinforcing back rib 51 and the second reinforcing back rib 52 to have a lateral force. Figure 4 The tendency of the first reinforcing back rib 51 to move away from each other in the B direction makes the end of the first reinforcing back rib 51 come into close contact with the mounting groove 11, thereby reducing the possibility of the fan plate 40 being dislodged due to impact and effectively offsetting the impact on both sides of the fan plate 40.

[0031] Specifically, the top of the lower crossbeam 30 is fixed with a first connector 31, which is movably connected to the adjacent second connector slot 44 to improve overall stability. The bottom of the upper crossbeam 20 is provided with a first connector slot 21, which is movably connected to the adjacent second connector 42 to improve overall stability. First, the upper crossbeam 20 or the lower crossbeam 30 is installed and fixed to the longitudinal frame 10. Then, the reinforcing component 50 and the sash plate 40 are installed in sequence. After the two are spliced ​​into a closed whole, the lower crossbeam 30 or the upper crossbeam 20 is installed to the longitudinal frame 10 to form the composite door structure. The reinforcing component 50 can improve the strength of the connection between the sash plate 40 and the longitudinal frame 10. On the other hand, when the sash plate 40 is impacted during use, the reinforcing component 50 can buffer the impact, thereby bearing the impact and improving the overall impact resistance.

[0032] like Figure 5 , 7 As shown in Figure 8, in this embodiment, the outer side of the second connector 42 is movably fitted with the buffer sleeve 43. Both the second connector 42 and the buffer sleeve 43 are spindle-shaped structures. The second connector 42 and the buffer sleeve 43 are located on the inner side of the whole formed by the first reinforcing back rib 51 and the second reinforcing back rib 52. The buffer sleeve 43 can play a buffering role between the first reinforcing back rib 51, the second reinforcing back rib 52 and the second connector 42, thereby improving the overall impact resistance.

[0033] like Figure 3 and 4As shown, in this embodiment, the end of the first reinforcing back rib 51 is an L-shaped structure. When the first reinforcing back rib 51 with an L-shaped end is installed, its end is placed inside the mounting groove 11. The L-shaped end makes it easy to install the first reinforcing back rib 51 on the mounting groove 11. The middle part of the first reinforcing back rib 51 and the middle part of the second reinforcing back rib 52 are both arc-shaped structures. The combination of the first reinforcing back rib 51 and the second reinforcing back rib 52 can be arranged inside the embedding groove 41.

[0034] In specific implementation, when installing the reinforcing component 50, the two ends of the first reinforcing back rib 51 can be squeezed to increase the distance between the first reinforcing back rib 51 and the second reinforcing back rib 52. At this time, the effective length between the two ends of the first reinforcing back rib 51 is reduced. Then, the two ends of the first reinforcing back rib 51 are aligned with the corresponding mounting groove 11, and the squeezing force at the end of the first reinforcing back rib 51 is removed. After the first reinforcing back rib 51 and the second reinforcing back rib 52 recover their deformation, the end of the first reinforcing back rib 51 is inserted into the inner side of the mounting groove 11. Then, screws are used to connect the end of the first reinforcing back rib 51 to the threaded hole inside the mounting groove 11. The screws are tightened with a screwdriver to fix the two, or a hex wrench can be used to fix the screws.

[0035] In this invention, the first reinforcing back rib 51 and the second reinforcing back rib 52 can be made of galvanized steel sheet. The galvanized steel sheet is selected with a thickness of 0.35mm to 0.6mm. This thickness range can provide sufficient cushioning effect, while also ensuring the strength and durability of the steel sheet. Galvanized steel sheet is existing technology and will not be described in detail here.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
