High-strength durable fiber composite wood door

Abstract

This utility model relates to the field of wooden door technology and discloses a high-strength, durable fiber composite wooden door, including a wooden door frame. Decorative panels are fixedly installed on both the front and rear sides of the wooden door frame. A fixed cylinder is fixedly installed in the center of the inner cavity of the wooden door frame, and a top rod is movably installed in the inner cavity of the fixed cylinder. This utility model's technical solution allows the wedge-shaped block on the top rod to push the ball rod, which in turn moves the rubber strip downwards. This ensures that the rubber strip contacts the ground while the wooden door is closed, thus blocking external dust and preventing it from entering the room. It also allows the rubber strip to separate from the ground, reducing wear and tear during opening and closing, thereby reducing the frequency of rubber strip replacement. Furthermore, the fixed cylinder and diagonal bracing enhance the stability of the four corners of the wooden door frame, improving the overall strength of the frame and extending the lifespan of the wooden door.

Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, specifically to high-strength durable fiber composite wooden doors. Background Technology

[0002] Composite doors use wood as the frame, various filling materials as the core, and various materials as the surface veneer. This type of door adds another layer of material between the wooden frame and the surface. Most composite doors use medium-density fiberboard (MDF) because MDF is easy to carve, easy to sand flat, and has minimal deformation.

[0003] A search revealed a high-strength, durable, and safe fiber composite wood door with publication number (CN217681362U). The door includes a base, a top cover, a pressing mechanism, a reinforcing mechanism, a reinforcing plate, a heat insulation plate, and fasteners. The base has an opening at the top, and a reinforcing mechanism is provided on the inner wall of the base's bottom. The reinforcing mechanism consists of a support plate and reinforcing ribs. Two support plates are positioned vertically, with the lower support plate located on the inner wall of the base's bottom. The upper support plate is connected to the lower support plate via reinforcing ribs. A reinforcing plate is located at the top of the reinforcing mechanism, and a heat insulation plate is located at the top of the reinforcing plate. A groove is formed at the top of the base, and a pressing mechanism is located within the groove. The sides of the bottom of the top cover are all located within the groove. The base and the top cover are connected by fasteners at the four corners and locked with bolts.

[0004] While this technical solution has been implemented, at least the following drawbacks remain: although it improves the strength of wooden doors, the gap between the door and the ground allows dust to enter the room. Furthermore, prolonged opening and closing of the door causes wear on the sealing strip, increasing the frequency of replacements for users. Therefore, improvements are urgently needed. Consequently, we propose a high-strength, durable fiber composite wooden door. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength and durable fiber composite wood door, which solves the problem mentioned in the background art that the gap between the wood door and the ground allows dust from the outside to enter the room, and that the long-term opening and closing of the wood door will cause the sealing strip to wear, thus increasing the frequency of replacement for users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength and durable fiber composite wooden door, comprising a wooden door frame, decorative panels fixedly installed on both the front and rear sides of the wooden door frame, a fixed cylinder fixedly installed in the middle of the inner cavity of the wooden door frame, a top rod movably installed in the inner cavity of the fixed cylinder, a wedge block fixedly installed at the lower end of the top rod, a ball stick penetrating through the middle of the lower end of the wooden door frame, the ball stick being positioned below the wedge block, a receiving groove being opened at the lower end of the wooden door frame, a rubber strip being provided in the inner cavity of the receiving groove, and the upper end of the rubber strip being fixedly connected to the lower end of the ball stick.

[0007] By adopting the above technical solution, the top rod can compress the first spring, while the wedge block on the top rod pushes the ball rod, which in turn moves the rubber strip downwards. This allows the rubber strip to contact the ground while the wooden door is closed, thus blocking external dust and preventing it from entering the room. Furthermore, after the top rod loses its pushing force from the door frame, the spring's elasticity allows the first and second springs to reset the top rod and ball rod respectively, separating the rubber strip from the ground. This reduces wear and tear on the rubber strip during opening and closing, thus reducing the frequency of replacement. Additionally, the use of a fixed cylinder and diagonal braces strengthens the stability of the four corners of the wooden door frame, improving its overall strength and extending the door's lifespan.

[0008] Optionally, a second spring is fixedly installed on both sides of the cue stick, and the other end of the second spring is fixedly connected to the wooden door frame.

[0009] By adopting the above technical solution and by setting the second spring, the cue stick can be driven to move upward and reset.

[0010] Optionally, the size of the rubber strip is adapted to the size of the receiving groove, and the rubber strip is movably connected to the receiving groove.

[0011] By adopting the above technical solution and setting up a receiving groove, the rubber strip can be stored.

[0012] Optionally, a first spring is fixedly installed at one end of the top rod, and the other end of the first spring is fixedly connected to the inner cavity of the fixed cylinder.

[0013] By adopting the above technical solution, the first spring is used to drive the push rod to reset, thus facilitating the next push of the cue stick.

[0014] Optionally, diagonal braces are fixedly installed on both the upper and lower sides of the fixed cylinder, and the diagonal braces are arranged symmetrically.

[0015] By adopting the above technical solution and setting diagonal braces, the structural strength of the wooden door frame can be improved.

[0016] Optionally, a door lock is provided on the front side of the decorative panel, and the door lock is detachably connected to the wooden door frame.

[0017] By adopting the above technical solution and setting a door lock, it is convenient to close and lock the wooden door.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution, through the design of a door frame, decorative panel, fixing cylinder, diagonal brace, wedge block, ball rod, and rubber strip, allows the top rod to compress the first spring. Simultaneously, the wedge block on the top rod pushes the ball rod, which in turn moves the rubber strip downwards. This ensures that the rubber strip contacts the ground while the wooden door is closed, preventing dust from entering the room. Furthermore, after the top rod loses its pushing force from the door frame, the spring's elasticity causes the first and second springs to reset, separating the rubber strip from the ground. This reduces wear and tear on the rubber strip during opening and closing, thus decreasing the frequency of replacement. Additionally, the fixing cylinder and diagonal brace enhance the stability of the four corners of the wooden door frame, improving its overall strength and extending the door's lifespan.

[0025] Please see Figure 1-3This utility model provides a technical solution: a high-strength and durable fiber composite wooden door, including a wooden door frame 1. Decorative panels 11 are fixedly installed on both the front and rear sides of the wooden door frame 1. A fixing cylinder 2 is fixedly installed in the middle of the inner cavity of the wooden door frame 1. A top rod 22 is movably installed in the inner cavity of the fixing cylinder 2. A wedge block 24 is fixedly installed at the lower end of the top rod 22. A ball stick 25 is inserted through the middle of the lower end of the wooden door frame 1. The ball stick 25 is located below the wedge block 24. A receiving groove 3 is opened at the lower end of the wooden door frame 1. A rubber strip 4 is installed in the inner cavity of the receiving groove 3. The upper end of the rubber strip 4 is fixedly connected to the lower end of the ball stick 25. One end of the top rod 22 is fixedly installed with a first spring 23, and the other end of the first spring 23 is fixedly connected to the inner cavity of the fixed cylinder 2. The first spring 23 drives the top rod 22 to reset, which facilitates the next push of the ball stick 25. The upper and lower sides of the fixed cylinder 2 are fixedly installed with diagonal braces 21, and the diagonal braces 21 are symmetrically arranged. The diagonal braces 21 can improve the structural strength of the wooden door frame 1. The front side of the decorative panel 11 is provided with a door lock 12, which is detachably connected to the wooden door frame 1. The door lock 12 facilitates the closing and locking of the wooden door.

[0026] A second spring 26 is fixedly installed on both sides of the cue stick 25. The other end of the second spring 26 is fixedly connected to the wooden door frame 1. The second spring 26 can drive the cue stick 25 to move upward and reset.

[0027] The size of the rubber strip 4 is adapted to the size of the receiving groove 3, and the rubber strip 4 is movably connected to the receiving groove 3. The rubber strip 4 can be stored in the receiving groove 3.

[0028] When the wooden door is closed, the top rod 22 on the door contacts the door frame. The reaction force of the door frame pushes the top rod 22 to the left, compressing the first spring 23. At the same time, the wedge block 24 on the top rod 22 pushes the ball rod 25, which in turn moves the rubber strip 4 downward. This ensures that the rubber strip 4 contacts the ground while the door is closed, thus blocking external dust and preventing it from entering the room. When the door is opened, after the top rod 22 loses the pushing force from the door frame, the springs rebound, and the first spring 23 and the second spring 26 respectively drive the top rod 22 and the ball rod 25 back to their original positions, separating the rubber strip 4 from the ground. This reduces wear and tear on the rubber strip 4 during opening and closing, thus reducing the frequency of replacement. Furthermore, the fixed cylinder 2 and the diagonal brace 21 enhance the stability of the four corners of the door frame 1, improving the overall strength of the door frame 1 and extending the service life of the door.
