Description

Technical Field

[0001] The utility model belongs to the technical field of wooden doors, and particularly relates to a damping and noise reduction type wooden door. Background Technique

[0002] A wooden door is a door body with a wooden structure. In order to maintain the structural strength of the wooden door, a U-shaped inner support beam is often installed inside the wooden door. Specifically, during the processing of the wooden door, first, the door body frame is processed and formed, then the inner support beam is fixed into the frame, and then the wooden door panel is installed on the door body frame.

[0003] After the wooden door is installed, in order to prevent the wind from blowing the wooden door and hitting the door frame, resulting in damage to the wooden door, such as deformation and reduced service life. In the prior art, a magnetic attraction method is used to adsorb between the wooden door and the wall. However, the magnetic attraction force is limited. Along with this, when the wind force is relatively large, or when someone closes the door with a heavy blow, the wooden door is still likely to hit the door frame heavily. As a result, under the strong impact force, the wooden door is severely deformed, and the first part to deform is the panel structure on the wooden door.

[0004] Therefore, although the magnetic attraction structure can solve the problem of keeping the wooden door from flipping under the wind force, in the case of a small wind force, the impact force of the wooden door is also small. Therefore, the magnetic attraction structure on the existing wooden door does not seem to be particularly practical.

[0005] At the same time, when the wind force flips the wooden door and hits the door frame, it not only causes deformation of the wooden door and affects its service life, but also generates a very large noise due to the high impact force.

[0006] The most fatal defect is that because the door frame is fixedly installed on the wall structure, under a strong impact, it is easy to cause deformation of the door frame. After the door frame is deformed, the wooden door cannot be closed. Moreover, once the door frame is deformed, it is very cumbersome to replace. Specifically, the door frame is fixed to the building structure. When replacing, it will inevitably cause damage to the building structure, such as damage to the paint on the wall and the cement structure of the door opening. After damage, it is very cumbersome and time-consuming to repair. Content of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a damping and noise reduction type wooden door.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A damping and noise reduction type wooden door, including a wooden door body, and a plurality of damping and noise reduction structures are installed on one side of the wooden door body facing the door frame;

[0010] The damping and noise reduction structure includes an elastic damping seat, a column-shaped sunk groove adapted to the elastic damping seat is opened on the wooden door body, and the elastic damping seat is slidably connected in the column-shaped sunk groove;

[0011] An inner slide bar that is fixedly connected to the elastic damping seat in a limited sliding manner is provided inside the cylindrical sink. A damping spring is sleeved on the inner slide bar, and the inner and outer ends of the damping spring are fixed to the elastic damping seat and the cylindrical sink respectively;

[0012] When an external force acts, the wooden door body strikes the door frame heavily, and the elastic damping seat retracts into the cylindrical sink. During the retraction process, the spring is compressed, achieving damping to reduce the impact force between the wooden door body and the door frame. When the wooden door body is in the closed state, the elastic damping seat is completely retracted into the cylindrical sink.

[0013] Preferably, the elastic damping seat is made of rubber material.

[0014] Preferably, a plurality of groove structures for increasing the friction force with the door frame are provided at the outer end of the elastic damping seat.

[0015] Preferably, door panel anti-cracking structures are fixedly connected to the front and rear side walls of the wooden door body.

[0016] Preferably, each of the door panel anti-cracking structures includes a plurality of frame-shaped grooves opened on the wooden door body, and a stainless steel frame side support is installed in the frame-shaped grooves;

[0017] The wooden door body is supported by the stainless steel frame side support.

[0018] Preferably, each of the door panel anti-cracking structures includes 2 concentrically arranged frame-shaped grooves;

[0019] An outer stainless steel frame side support is lined on the outer frame-shaped groove, and an inner stainless steel frame side support is lined on the inner frame-shaped groove;

[0020] The outer stainless steel frame side support and the inner stainless steel frame side support are flush with the side wall of the wooden door body.

[0021] Preferably, the outer stainless steel frame side supports are tightened by a plurality of long tensioning screws; the inner stainless steel frame side supports are tightened by a plurality of long tensioning screws;

[0022] The long tensioning screws penetrate through the wooden door body, and the long tensioning screws are countersunk head screws.

[0023] Preferably, a suction and pull mechanism is installed at the lower corner of the wooden door body;

[0024] The suction and pull mechanism includes a suction and pull plate fixedly connected to the wooden door body, and a plurality of curved grooves are opened on the suction and pull plate;

[0025] The suction and pull mechanism further includes a suction and pull seat fixedly connected to the wall, and a plurality of sink balls adapted to the curved grooves are fixedly connected to the suction and pull seat;

[0026] When the wooden door body is opened, the sink balls are limited in the curved grooves.

[0027] Preferably, there is magnetic attraction between the suction plate and the sinking ball;

[0028] The material of the sinking ball is a permanent magnet, and the material of the suction plate is iron.

[0029] The utility model has the following beneficial effects:

[0030] 1. When an external force (such as wind force) acts, the wooden door body hits the door frame heavily, and the elastic damping seat retracts into the cylindrical sinking groove. During the retraction process, the spring is compressed, realizing damping to reduce the impact force between the wooden door body and the door frame. When the wooden door body is in the closed state, the elastic damping seat is completely retracted into the cylindrical sinking groove. In this process, firstly, since the elastic damping seat is made of elastic rubber material, it can protect the door frame while forming a buffer by the deformation of the elastic damping seat. Secondly, when the elastic damping seat is completely retracted into the cylindrical sinking groove, the spring deforms and shortens, forming a buffer through the deformation of the spring (which is a conventional application of the inherent property of the spring in the prior art). In this way, a buffer is formed by using the elastic damping seat, thereby protecting the door body and the door frame from excessive impact force during the impact process.

[0031] Meanwhile, when the door body is in the fully closed state, under the touch pressure of the door frame, the elastic damping seat is completely retracted into the cylindrical sinking groove, thereby realizing that the door body can be fully closed tightly.

[0032] By the above method, the impact force can also be buffered, realizing a reduction in the impact noise.

[0033] 2. During the working process, the outer stainless steel frame and the inner stainless steel frame on both sides of the wooden door body are tightened and fixed by the long tension screw rod. At this time, since the outer stainless steel frame and the inner stainless steel frame are lined on the panel of the wooden door body, the panel of the wooden door body is kept from cracking under the support of the outer stainless steel frame and the inner stainless steel frame, especially after being heavily hit or impacted, maintaining the stability of the structure.

[0034] Moreover, under the clamping of the outer stainless steel frame and the inner stainless steel frame on the front and rear sides, the entire door body structure is in a tightened state and is more stable in structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Example 1

[0048] As Figures 1-7 shown, a damping and noise reduction wooden door includes a wooden door body 1. The main structure of the wooden door body 1 is the same as that of the existing wooden door, and is the same as the structure of the existing wooden door body 1. A hinge shaft is fixedly installed at the door edge part.

[0049] In the same installation manner as the existing door body, the wooden door body 1 is installed on the door frame through the hinge shaft 11. When the door is closed, the edge part of the wooden door body 1 abuts against the flange part of the door frame.

[0050] In order to solve the problems that when the door body is flipped by strong wind, the door body hits the door frame, causing the door frame to become loose, deformed, and the structural shape of the wooden door body 1 to deform, resulting in a reduction in the service life of the wooden door body 1. A plurality of damping and noise reduction structures 2 are installed on one side of the wooden door body 1 facing the door frame; the damping and noise reduction structures 2 are arranged at the upper and lower parts of the side wall of the wooden door body 1 and are distributed in a horizontal equidistant distribution manner.

[0051] Through the damping and noise reduction structure 2, when the door body is hit heavily on the door frame under the action of an external force, the damping and noise reduction structure 2 forms a buffer to reduce the impact force and reduce the noise generated by the impact.

[0052] Specifically, the damping and noise reduction structure 2 includes an elastic damping seat 21 (the material of the elastic damping seat 21 is rubber material). Correspondingly, a cylindrical sunk groove adapted to the elastic damping seat 21 is opened on the wooden door body 1, and the elastic damping seat 21 is slidably connected in the cylindrical sunk groove.

[0053] Specifically, an internal slide bar 22 for limiting and slidingly connecting the elastic damping seat 21 is fixedly connected in the cylindrical sunk groove. In the same existing limiting sliding manner, the shape of the internal slide bar 22 is T-shaped. Correspondingly, a matching chute is opened on the elastic damping seat 21, and the internal slide bar 22 is limited and slid in the chute.

[0054] At the same time, a damping spring 23 is sleeved on the internal slide bar 22, and the inner and outer ends of the damping spring 23 are fixed on the elastic damping seat 21 and the cylindrical sunk groove.

[0055] When under the action of an external force, the wooden door body 1 hits the door frame heavily, the elastic damping seat 21 retracts into the cylindrical sink. During the retraction process, the spring is compressed, reducing the impact force between the wooden door body 1 and the door frame. When the wooden door body 1 is in the closed state, the elastic damping seat 21 is completely retracted into the cylindrical sink. In this process, first, since the elastic damping seat 21 is made of elastic rubber material, while protecting the door frame, a buffer is formed by the deformation of the elastic damping seat 21. Second, when the elastic damping seat 21 is completely retracted into the cylindrical sink, the damping spring 23 deforms and shortens, forming a buffer through the deformation of the damping spring 23 (a conventional application of the inherent property of the spring in the prior art). In this way, a buffer is formed by the elastic damping seat 21, thereby protecting the door body and the door frame from excessive impact force during the impact process.

[0056] At the same time, when the door body is in the fully closed state, under the touch pressure of the door frame, the elastic damping seat 21 is completely retracted into the cylindrical sink, thus enabling the door body to be fully closed tightly.

[0057] Through the above method, the impact force can also be buffered, reducing the impact noise.

[0058] A number of groove structures 211 for increasing the friction with the door frame are provided at the outer end of the elastic damping seat 21. By increasing the friction, when the elastic damping seat 21 abuts against the door frame, the stability of the abutment is increased, ensuring that the door frame can be fully touched and pressed to form a buffer.

[0059] Embodiment 2

[0060] As Figures 1-7 shown, on the basis of the structure of Embodiment 1, door panel anti-cracking structures are fixedly connected to the front and rear side walls of the wooden door body 1. Through the door panel anti-cracking structures, the door panel of the wooden door body 1 is further protected to prevent the door panel from cracking after long-term use. At the same time, it has the same effect as the elastic damping seat 21 elastically buffering the impact force, aiming to protect the door body structure and avoid deformation of the door body and the defect of cracking after deformation due to impacts and other factors during use.

[0061] Specifically, the door panel anti-cracking structures each include a number of frame-shaped grooves A opened on the wooden door body 1, and a stainless steel frame is installed in the frame-shaped grooves; specifically, the door panel anti-cracking structures each include 2 concentric frame-shaped grooves A, and the wooden door body 1 is supported by the stainless steel frame.

[0062] At the same time, an outer stainless steel frame 31 is lined on the outer frame-shaped groove, and an inner stainless steel frame 32 is lined on the inner frame-shaped groove; the outer stainless steel frame 31 and the inner stainless steel frame 32 are flush with the side wall of the wooden door body 1 (to maintain aesthetics).

[0063] Meanwhile, the outer stainless-steel frame side frames 31 are tightened by a number of long tensioning screws 33; the inner stainless-steel frame side frames 32 are tightened by a number of long tensioning screws 33; the long tensioning screws 33 penetrate through the wooden door body 1, and the long tensioning screws 33 are countersunk screws.

[0064] During the working process, the outer stainless-steel frame side frames 31 and the inner stainless-steel frame side frames 32 on both sides of the wooden door body 1 are tightened and fixed by the long tensioning screws 33. At this time, since the outer stainless-steel frame side frames 31 and the inner stainless-steel frame side frames 32 are lined on the panel of the wooden door body 1, therefore, the panel of the wooden door body 1 is kept from cracking under the support of the outer stainless-steel frame side frames 31 and the inner stainless-steel frame side frames 32, especially after being severely hit or impacted, and the stability of the structure is maintained.

[0065] Moreover, under the clamping of the outer stainless-steel frame side frames 31 and the inner stainless-steel frame side frames 32 on the front and rear sides, the entire door body structure is in a tightened state and is more stable in structure.

[0066] After the above-mentioned outer stainless-steel frame side frames 31 and inner stainless-steel frame side frames 32 are polished, the surface is smooth, so they can also play a role in beautifying the door body at the same time.

[0067] Embodiment 3

[0068] As Figures 1-7 shown, on the basis of the structure of Embodiment 1, in this embodiment, when in the open state, it is adsorbed on the wall like the existing door body to prevent the door body from flipping randomly. The same as the existing design of the adsorption structure at the lower end of the door body, a suction and pull mechanism is installed at the lower corner part of the above-mentioned wooden door body 1 (the suction and pull mechanism is located on the side of the door body facing the wall); the suction and pull mechanism includes a suction and pull plate 41 fixedly connected to the wooden door body 1, and a number of curved grooves 411 are opened on the suction and pull plate 41.

[0069] Correspondingly, the suction and pull mechanism further includes a suction and pull seat 43 fixedly connected to the wall, and a number of sink balls 431 adapted to the curved grooves 411 are fixedly connected to the suction and pull seat 43; when the wooden door body 1 is opened, the sink balls 431 are limited in the curved grooves 411.

[0070] The same as the existing magnetic adsorption method, magnetic adsorption occurs between the suction and pull plate 41 and the sink balls 431; the material of the sink balls 431 is a permanent magnet, and the material of the suction and pull plate 41 is iron.

[0071] During the process of opening the door, the sink balls 431 are adsorbed in the curved grooves 411, thereby being able to prevent the door body from flipping randomly.

[0072] And when the wind force is extremely strong, the door body breaks free from the adsorption force, and the above elastic damping seat 21 structure protects the door body.

[0073] Meanwhile, similar to the principle of forming a buffer by the deformation of the above damping spring, a spring groove is formed on the above-mentioned suction plate 41, and a contact spring 42 protruding from the spring groove is fixedly connected in the spring groove. When the door body is opened towards the wall, at this time, the contact spring 42 pre-contacts the suction seat 43 and is compressed and retracted into the spring groove. During this process, a buffer is formed by the deformation of the spring to protect the door body. Moreover, the above sink ball 431 is adsorbed in the curved groove 411 to hold the door body.

[0074] Certainly, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
