[0026] The frame body 1, groove 101, recessed platform 102, wooden door body 2, handle 201, lock body 202, hydraulic hinge 3, movable block 4, positioning plate 401, buffer spring 402, recessed hole 403, vibration damping pad 404, and guide rod 405 components in this application are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Example
[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: a wooden door with a protective frame and a buffer function, including a frame body 1, and further including:
[0028] Three hydraulic hinges 3 are installed inside the left side of the frame body 1.
[0029] The wooden door body 2 is movably installed via hydraulic hinge 3. A lock body 202 is provided at the right end of the wooden door body 2, and a handle 201 is fixedly installed at the middle of the front of the wooden door body 2.
[0030] This technical solution: By setting up the hydraulic hinge 3, the closing speed of the wooden door body 2 within the frame body 1 can be controlled. The main working principle of the hydraulic hinge 3 is to achieve a buffering effect through the directional flow of high-density oil in a sealed container. When the door is opened to 60°, the hydraulic hinge 3 will automatically activate the slow closing function to reduce the impact and noise when closing the door, ensuring that the door can close gently, thereby achieving the ability to buffer and protect the door when closing. In addition, the use of the hydraulic hinge 3 not only improves the comfort of use, but also reduces the noise and impact caused by sudden closing of the door, making it particularly suitable for places that require a quiet environment, such as bedrooms and offices. Example
[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a recessed platform 102 is provided on the rear side of the frame body 1. Three equally spaced grooves 101 are provided on the right end of one side of the recessed platform 102. A movable block 4 is slidably connected to one end of the inner cavity of the groove 101, and the rear end of the movable block 4 is located outside the groove 101. The top section of the movable block 4 is a rectangular body with an arc-shaped protrusion on the rear side. A shock-absorbing pad 404 is adhered to the rear side of the movable block 4. A number of buffer springs 402 are fixedly connected to the front side of the movable block 4. A positioning plate 401 adapted to the groove 101 is fixedly connected to the end of the buffer spring 402 away from the movable block 4. A guide rod 405 located inside the buffer spring 402 is fixedly connected to the rear side of the positioning plate 401. The rear end of the guide rod 405 slides on the inner surface of the movable block 4.
[0032] This technical solution: By setting the groove 101, the positioning plate 401 can be inserted into the groove 101 via the movable block 4. When the door is closed with excessive force or due to strong winds, the right end of the front of the wooden door body 2 will contact the shock-absorbing pad 404 when it enters the frame body 1. Affected by the arc-shaped protrusion on the rear side of the movable block 4, the adhesive shock-absorbing pad 404 is also arc-shaped. Thus, when the wooden door body 2 touches the shock-absorbing pad 404, it is in line contact, which can reduce the contact area between the two and avoid the generation of large noise. When the shock-absorbing pad 404 is impacted, it can drive the movable block 4 to retract into the groove 101. With the movement of the movable block 4, the buffer spring 402 can be compressed with the assistance of the positioning plate 401 and the guide rod 405 to achieve buffering, further improving the buffering capacity of the frame wooden door and ensuring the service life of the frame wooden door. Example
[0033] Based on Embodiment 2, this utility model is as follows: Figure 5 As shown, recesses 403 are provided at the top and bottom of the rear end of the active block 4.
[0034] This technical solution: By setting the recessed hole 403, when the wooden door body 2 is not closed, the tool can be inserted into the recessed hole 403 of the corresponding movable block 4. Then, when pulled outward, the movable block 4 and the positioning plate 401 can be taken out from the groove 101, which is convenient for the user to replace them according to the usage situation.
[0035] It should be noted that the longitudinal section of the guide rod 405 is a T-shaped structure, which is not shown in the figure.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
