Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, and in particular to a wooden door with safety protection against pinching. Background Technology

[0002] When traditional wooden doors close, a narrow gap is formed between the door panel and the door frame / wall, making it easy for users' fingers, especially children's fingers, to get caught, leading to soft tissue contusions, fractures, or even more serious injuries. Wooden doors without buffer devices close quickly and with strong impact, and even if there are no fingers in the gap, the impact may still damage the door panel / wall or cause accidental impact to people near the door. Therefore, it is necessary to design a safety-protected anti-pinch wooden door to reduce the above risks.

[0003] Chinese Patent Publication No. CN219910446U discloses a child safety door with anti-pinch mechanism, belonging to the field of safety door technology. This door includes a door panel with anti-pinch openings on both sides, the openings being positioned within a child's reach. A door frame contains an active gear with a first rack meshing at its lower end and a driven gear meshing at its upper end. The driven gear meshes with a second rack, which is fixedly connected to a locking block. An elastic element is mounted on the first rack, which can push the rack outwards from the door frame, thereby moving the locking block outwards as well. When the door panel is opened, the anti-pinch mechanism automatically pops out; the door panel needs to be closed by turning the handle. This effectively prevents the door panel from being blown shut by wind, thus avoiding injury to the child. The anti-pinch openings also prevent the door panel from pinching the child.

[0004] Although the devices described in the aforementioned documents can be activated to prevent pinching, they have a relatively complex structure, high installation and maintenance costs, and cannot provide a buffering effect when the door is closed, still posing a risk of pinching and injuring people.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figure 1 As shown, a safety-protected anti-pinch wooden door includes a ground 1, a wall 2 fixedly connected to the upper end of the ground 1, a wooden door assembly 3 rotatably connected to the left side of the wall 2, a partition assembly 4 fixedly connected to the right rear end of the wooden door assembly 3, and a buffer assembly 5 rotatably connected to the upper front end of the wooden door assembly 3 and the wall 2.

[0026] like Figure 2As shown, the wooden door assembly 3 includes a door panel 31 rotatably connected to the left side of the wall 2. Rectangular grooves 32 are provided on the lower part of both sides of the door panel 31. T-shaped rubber plates 33 are fixedly connected to the middle of the two rectangular grooves 32. Rubber plates 34 are fixedly connected to both ends of the two T-shaped rubber plates 33. Grooves 35 are provided in the middle of the four rubber plates 34.

[0027] The four rubber panels 34 are made of rubber, which is soft and has a certain degree of elasticity. Even when the door panel 31 is closed, children will not hurt their fingers if they touch the side of the door panel 31. This can play a protective role. At the same time, the T-shaped rubber panel 33 can separate the indoor and outdoor spaces and maintain the independence of the indoor space.

[0028] Meanwhile, the position and number of rectangular grooves 32 and rubber plates 34 are not fixed and can be designed according to the user's specific usage.

[0029] like Figure 3 As shown, the partition assembly 4 includes a rotating part 41 located on the right rear side of the door panel 31. Slider 42 is fixedly connected to both sides of the front end of the rotating part 41. A magnetic block 43 is fixedly connected to the lower middle part of the front end of the rotating part 41. A fixed seat 44 is slidably connected to the outer surfaces of the two sliders 42. The fixed seat 44 is fixedly connected to the door panel 31. A magnetic block 45 is fixedly connected to the middle of the bottom wall of the inner surface of the fixed seat 44. The magnetic block 43 is located on the upper side of the magnetic block 45.

[0030] like Figure 4 As shown, the rotating part 41 includes a housing 411 located on the right rear side of the door panel 31. Sliding rods 412 are slidably connected to both sides of the housing 411. Push plates 413 are fixedly connected to the upper ends of the two sliding rods 412 through the housing 411. Push plates 414 are fixedly connected to the lower ends of the two sliding rods 412 through the housing 411. Two springs 415 are fixedly connected to the lower end of the push plate 413 and the upper end of the housing 411. The two springs 415 are sleeved on the upper side of the outer surface of one of the sliding rods 412 that are close to each other. An L-shaped rod 416 is rotatably connected to the front side wall of the inner surface of the housing 411. Four positioning grooves 417 arranged in a circular array are opened on the front side of the outer surface of the L-shaped rod 416. A positioning rod 418 is fixedly connected to the middle of the upper end of the push plate 414.

[0031] Specifically, the positioning rod 418 and the four positioning slots 417 are all matched in shape.

[0032] Specifically, a rubber sleeve is fixedly connected to the upper side of the outer surface of the L-shaped rod 416.

[0033] In this embodiment, when safety protection is required, the push plate 413 is pressed downwards. The push plate 413 pushes the two sliding rods 412 and the push plate 414 downwards, causing the positioning rod 418 to slide down until it slides out of the corresponding positioning groove 417. Then, the L-shaped rod 416 can be rotated 90° to the right. After that, the push plate 413 is released, and under the elastic force of the spring 415, the push plate 413 is pushed upwards, thereby causing the... The sliding rod 412, the push plate 414, and the positioning rod 418 move upwards, and the positioning rod 418 slides into the corresponding positioning groove 417, thereby fixing the L-shaped rod 416. When the door panel 31 rotates, the L-shaped rod 416 is located between the door panel 31 and the wall 2, blocking the closing of the door panel 31 and leaving a gap between the door panel 31 and the wall 2 to prevent the hand from being pinched. The rubber sleeve on the outer surface of the L-shaped rod 416 can play a buffering role to prevent the impact from damaging the door panel 31 and the wall 2.

[0034] When it is necessary to remove or replace the rotating part 41, the rotating part 41 can be slid upward to slide the slider 42 out of the fixed seat 44. Then, the new rotating part 41 is slidably connected to the fixed seat 44 through the slider 42. The rotating part 41 is placed into the fixed seat 44, and the magnetic block 1 43 and magnetic block 2 45 attract each other to fix the rotating part 41 to the fixed seat 44.

[0035] Example 2

[0036] Based on Embodiment 1, this embodiment adds a buffer component 5, which can slow down the closing speed of the door panel during the closing process, reduce the instantaneous impact force, and reduce the risk of pinching injury.

[0037] like Figure 5 As shown, the buffer assembly 5 includes a cylindrical shell 51 rotatably connected to the upper front end of the door panel 31. A second spring 52 is fixedly connected to the right side wall of the inner surface of the cylindrical shell 51. A second slide rod 53 is fixedly connected to the left end of the second spring 52. The second slide rod 53 is slidably connected to the cylindrical shell 51. The right side of the second slide rod 53 is rotatably connected to the wall 2.

[0038] In this embodiment, when the door panel 31 is pushed open by hand, the cylindrical housing 51 and the second slide rod 53 are rotated. The second slide rod 53 slides and stretches the second spring 52. When the door panel 31 is stopped being pushed, the second spring 52 contracts and drives the second slide rod 53 to slide, thereby driving the door panel 31 to close. The second spring 52 can play a buffering role to prevent the door panel 31 from closing quickly and pinching the user.
