Description

Technical Field

[0001] The utility model relates to the technical field of composite doors, in particular to a composite sound insulation door. Background Art

[0002] Wooden doors include solid wood doors and composite wood doors. Solid wood doors need to be made of a whole piece of wood and have a high cost. The general structure of composite doors is door core + panel. Most existing door cores use composite boards pressed from materials such as sawdust, which makes the cost of the door core low. However, the disadvantage is that the structure of this type of door core is simple and the sound insulation effect is poor. At the same time, most existing panels are installed on the outer side of the door core with environmentally friendly glue. Therefore, with the long-term use of the composite door, the panel will not be firmly installed on the outer side of the door core, thereby affecting the service life of the composite door.

DETAILED DESCRIPTION

[0022] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0023] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0024] like Figure 1-2 As shown, a composite soundproof door in this embodiment includes a door core 100 and door panels 110 provided on both sides of the door core 100. The door core 100 includes a frame 210 and a sound insulation board 220 mounted in the frame 210. The sound insulation board 220 is of an existing structure. The sound insulation board 220 is mounted in the frame 210 in a snap-fit manner, so that the door core 100 thus manufactured has better sound insulation performance, and the composite soundproof door thus manufactured has better sound insulation performance.

[0025] The frame 210 is rectangular. When the sound insulation board 220 is snap-fitted and installed in the frame 210, the outer side of the sound insulation board 220 can be flush with the outer side of the frame 210. This facilitates the door panel 110 to be adhered and pressed to the two side surfaces of the door core 100 by gluing. In actual use, the door panel 110 is made of solid wood and is compositely arranged on the two side surfaces of the door core 100 to strengthen the strength of the door core 100, thereby forming a door body.

[0026] In this embodiment, the frame 210 and the door panel 110 have corresponding sides and are provided with receiving grooves 130 at the upper and lower ends. The receiving grooves 130 are provided with reinforcement components for fixing the door panel 110 to the two sides of the door core 100.

[0027] A reinforcement hole 201 is provided on the side wall of the accommodating groove 130 located at the door panel 110 . The reinforcement assembly includes a mounting plate 140 . The mounting plate 140 is provided with an expansion piece extending into the corresponding reinforcement hole 201 .

[0028] In this embodiment, the reinforcement assembly is provided to improve the installation strength of the door panel 110 on both sides of the door core 100, thereby preventing the door panel 110 from being loosely installed on both sides of the door core 100 due to long-term use, thereby reducing the service life of the door body.

[0029] In actual use, the expansion piece is extended into the corresponding reinforcement hole 201, and the mounting plate 140 is fixedly installed in the receiving groove 130 by countersunk bolts, so that the reinforcement component can be installed in the receiving groove 130. At this time, the expansion piece expands and tightens in the reinforcement hole 201, thereby making the connection between the expansion piece and the reinforcement hole 201 tighter, which is beneficial for the door panel 110 to be fastened to the two sides of the door core 100 through it.

[0030] Combine Figure 3 and Figure 4 As shown, in this embodiment, the expansion member includes a fixed cylinder 310 with a cavity 311 therein, and an inner wall of the cavity 311 is provided with a protrusion portion 312 at one end along its circumference, and an inclined surface is provided on the protrusion portion 312 along its circumference. One end of the fixed cylinder 310 is provided with gap grooves 411 evenly distributed along its circumference, and a movable movable column 320 is provided in the cavity 311, and an extrusion inclined surface 321 matching the inclined surface is provided on the movable column 320. The movable column 320 moves toward the protrusion portion 312 to drive the extrusion inclined surface 321 to extrude the inclined surface to realize the outward expansion of the protrusion portion 312.

[0031] In this embodiment, the cavity 311 is open at both ends, with a protrusion 312 provided at one end and the other end fixedly connected to the mounting plate 140 by welding. Due to the provision of the gap groove 411, the protrusion 312 is evenly divided into a plurality of bendable and deformable expansion portions.

[0032] The inclined surface, the movable column 320, and the extrusion inclined surface 321 are provided so that in the initial state, that is, when the expansion portion is not subjected to force, the movable column 320 is slidably provided in the cavity 311. At this time, the protrusion portion 312 can limit the movable column 320 to prevent the movable column 320 from sliding out of the cavity 311. When the fixed cylinder 310 is inserted into the reinforcement hole 201, the movable column 320 moves toward the protrusion portion 312 in the cavity 311, so that the extrusion inclined surface 321 on it presses the inclined surface, which can drive the expansion portion to bend and expand outward, thereby increasing the diameter of the fixed cylinder 310 located at the protrusion portion 312, thereby better achieving its expansion and tightening in the reinforcement hole 201.

[0033] Among them, in order to improve the effect of the fixed tube 310 on tightening the inner wall of the reinforcement hole 201, a protrusion 412 is provided along the circumference of the outer wall of the fixed tube 310 located at the protrusion portion 312. By utilizing the setting of the protrusion 412, when the expansion part bends and expands outward, the protrusion 412 can better tighten the inner wall of the reinforcement hole 201, so that the tightening effect of the expansion part is better.

[0034] In this embodiment, in order to better facilitate the operator to drive the movable column 320 outside the accommodating groove 130 to move toward the protrusion portion 312, so that the expansion part is tightened in the reinforcement hole 201, a threaded hole 421 is provided on the corresponding cavity 311 on the mounting plate 140, and the threaded hole 421 is threadedly connected with a first bolt 330 for driving the movable column 320 to move toward the protrusion portion 312.

[0035] Through the above-mentioned structure, this embodiment enables the first bolt 330 to be threadedly connected to the corresponding threaded hole 421 and extended into the corresponding cavity 311 by screwing, thereby abutting and pushing the movable column 320 to move toward the protrusion portion 312, thereby achieving expansion of the expansion piece, and the operation is simple and convenient.

[0036] like Figure 2 As shown, in this embodiment, the frame 210 includes a first block 2101 and a second block 2102 that are sequentially spliced together, and the opposite splicing ends of the first block 2101 and the second block 2102 are connected by a second bolt.

[0037] In this embodiment, the first block 2101 is the short side of the door body, and the second block 2102 is the long side of the door body, wherein the accommodating groove 130 is arranged on the outer wall of the second block 2102 and is located at the upper and lower ends, and the relative splicing ends of the first block 2101 and the second block 2102 are connected by a second bolt, thereby better realizing the splicing installation of the frame 210.

[0038] Combine Figure 5 As shown, in this embodiment, the inner side wall of the frame 210 protrudes outward to form a snap-in block 511 , and the surrounding side walls of the sound insulation board 220 are concave to form a snap-in groove 221 for the corresponding snap-in block 511 to be snapped into.

[0039] During actual use of this embodiment, the inner side walls of the first block 2101 and the second block 2102 both protrude outward to form a snap-in block 511, and the opposite ends of the snap-in block 511 are arranged at an angle. Thus, the snap-in block 511 does not interfere with the splicing between the first block 2101 and the second block 2102 to form the frame 210. By utilizing the coordinated arrangement of the snap-in groove 221 and the snap-in block 511, the sound insulation board 220 can be preferably snap-in installed in the frame 210.

[0040] In this embodiment, a decorative panel 120 is provided on one side of the door panel 110 .

[0041] In this embodiment, the decorative panel 120 is made of medium-density fiberboard glued with veneer. Therefore, it is preferable to perform carving, painting and other decorations on the decorative panel 120 to make it more beautiful and have a better touch. In actual use, the decorative panel 120 is adhered to the outer surface of the door panel 110 with environmentally friendly glue. The size of the decorative panel 120 is adapted to the size of the door panel 110.

[0042] Working principle: When assembling the composite soundproof door, first assemble the three sides of the frame 210, then match the snap-in groove 221 on the sound insulation board 220 with the corresponding snap-in block 511, so that the sound insulation board 220 slides into the assembled frame 210, and then splices the last side of the frame 210 to complete the assembly of the door core 100; then adhere the door panel 110 to the two sides of the door core 100 by glue, then extend the expansion piece into the corresponding reinforcement hole 201, and fix the mounting plate 140 to the accommodating groove 130 by the countersunk bolt. At this time, screw the first bolt 330 in the threaded hole 421 to extend it into the cavity 311, so that the expansion piece is tightened in the reinforcement hole 201, and finally, adhere the decorative panel 120 to the outer surface of the door panel 110 by glue to complete the assembly of the composite soundproof door.

[0043] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
