Description

Technical Field

[0001] This utility model relates to the field of door and window structure technology, and in particular to a swing door that can be locked at any opening degree. Background Technology

[0002] Hinged doors are a common type of door. To prevent airflow from affecting the door's position when it's open, doorstops are usually installed to lock it in one position. This means that with the doorstop installed, the hinged door can only be locked at a fixed angle, typically the fully open position. When fully open, a hinged door is in a state of complete ventilation, which can lead to strong airflow and affect the comfort of people inside. Furthermore, a fully open hinged door also allows a complete view of the interior, compromising the privacy of those inside.

[0003] Patent CN218324410U discloses a novel door catcher and door. The novel door catcher includes a base and a body. The base has a through hole and a receiving cavity communicating with the through hole. The body includes an elastic body and a stop. The elastic body is disposed on the stop. The maximum radial cross-sectional diameter of the elastic body is larger than the diameter of the through hole. The elastic body is elastic, allowing it to move in and out of the through hole based on elastic deformation under external force. After the external force disappears, it is fixed relative to the base by engaging with the through hole at its maximum radial cross-section. Using an elastic body to replace the spring, base, and housing of existing novel door catchers simplifies the product structure. The elasticity allows the door to be fixed by embedding into the base, and it can also be disengaged by external force, preventing failure due to aging and deformation, thus extending the product's lifespan while ensuring safety. However, because the door catcher can only be installed in a fixed position, the door can only be locked in the position of the door catcher after opening. In other positions, the door cannot be locked. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a swing door that can be locked at any opening degree, in order to solve the problem that current swing doors can only be locked in a fixed position after being opened.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A hinged door that can be locked at any opening degree includes a door leaf. The door leaf has a braking device at its bottom on the side away from its rotation center. The braking device includes a pressure block that is vertically slidably connected to the bottom of the door leaf, a brake pad that is fixedly connected to the bottom of the pressure block, and a drive mechanism disposed on the door leaf for driving the pressure block to move up and down.

[0007] Furthermore, a pivot is rotatably connected through the middle of the door leaf, and a handle is fixedly connected to the end of the pivot. The drive mechanism includes a swing arm and a pull rod arranged sequentially from top to bottom between the pivot and the pressure block. One end of the swing arm is fixedly connected to the pivot, and the other end is rotatably connected to the upper end of the pull rod. The lower end of the pull rod is connected to the pressure block.

[0008] Furthermore, corner brackets are fixedly connected to the corners of the door leaf by screws that pass through the door leaf.

[0009] Furthermore, a sliding plate is provided between the pull rod and the pressure block. The top of the sliding plate is rotatably connected to the pull rod, and the bottom of the sliding plate is fixedly connected to the pressure block. The sliding plate is provided with a vertical second strip hole for the screw to pass through.

[0010] Furthermore, the top of the pull rod is a hook, and the swing arm is rotatably connected to the hook tip; after turning the handle, the pull rod is moved upward, and the hook is hung on the rotating shaft.

[0011] Furthermore, one side of the door leaf is fixedly connected to a wheel frame by a screw that passes through the door leaf. The bottom of the wheel frame is rotatably connected to an auxiliary support wheel that can walk along the ground. The wheel frame has a vertical first strip hole at a position corresponding to the screw, and the screw passes through the first strip hole.

[0012] Furthermore, the brake pads are rubber plates.

[0013] The positive effects of this utility model are:

[0014] This utility model includes a door leaf and a pivot, swing arm, pull rod, sliding plate, pressure block, and brake pad mounted on the door leaf. Turning the handle on the pivot can move the brake pad up and down. When the brake pad moves down, it contacts the ground, locking the door leaf in place using friction between the brake pad and the ground. When the brake pad moves up, the door leaf can rotate normally. Therefore, the brake pad can lock the door leaf at any angle after it is opened, allowing the airflow through the doorway to be adjusted by changing the door opening to meet the ventilation needs of the house, while also protecting the privacy of the people inside to a certain extent.

[0023] Example 1

[0024] like Figure 1 As shown, a swing door that can be locked at any opening degree is installed in the doorway of the wall 1. It includes a rectangular door leaf 2, and the door leaf 2 is surrounded by a door frame 4. The left side of the door frame 4 is rotatably connected to the part of the wall 1 located in the doorway by a hinge. A braking device is provided at the bottom right side of the door frame 4.

[0025] like Figures 1 to 6 As shown, the braking device includes a rectangular pressure block 16 that is vertically slidably connected to the lower right corner of the door frame 4, a rectangular brake pad 17 that is fixedly connected to the bottom of the pressure block 16, and a driving mechanism provided on the door leaf 2 for driving the pressure block 16 to move up and down. The brake pad 17 is a rectangular rubber plate attached to the bottom of the pressure block 16.

[0026] The drive mechanism can move the pressure block 16 up and down, which in turn moves the brake pad 17 up and down. When the door 2 is opened, the drive mechanism moves the pressure block 16 downward, causing the brake pad 17 to press against the ground. The friction between the brake pad 17 and the ground locks the door 2 in place, preventing the opening of the door 2 from being affected by airflow. Because the brake pad 17 can lock the door 2 at any angle after it is opened, the amount of airflow through the doorway can be changed by adjusting the opening of the door 2, thus meeting the ventilation needs of the house and protecting the privacy of the people inside to a certain extent.

[0027] Example 2

[0028] The difference between this embodiment and Embodiment 1 is that:

[0029] A pivot 11 is rotatably connected through the right center of the door frame 4. Both ends of the pivot 11 are fixedly connected to spherical handles 3. The drive mechanism includes a swing arm 12 and a pull rod 13 arranged sequentially from top to bottom between the pivot 11 and the pressure block 16. One end of the swing arm 12 is a sleeve fitted onto the pivot 11, and a set screw is screwed onto the sleeve. The inner end of the set screw abuts against the pivot 11, thereby fixing the swing arm 12 to the pivot 11. The outer end of the swing arm 12 is rotatably connected to the upper end of the pull rod 13, and the lower end of the pull rod 13 is connected to the pressure block 16.

[0030] At each of the four corners of the door frame 4, L-shaped corner brackets 5 are fixedly connected to the door leaf 2 by screws 9 passing through the door leaf 2 and nuts screwed to the ends of the screws 9, for connecting the four profiles of the door frame 4 into one piece. A rectangular sliding plate 14 is provided between the pull rod 13 and the pressure block 16. The sliding plate 14 is set vertically, the top of the sliding plate 14 is rotatably connected to the lower end of the pull rod 13, and the bottom of the sliding plate 14 is welded to the top of the pressure block 16. The sliding plate 14 has a vertical second strip hole 15 for the screws 9 to pass through. The second strip hole 15 can prevent the sliding plate 14 from interfering with the screws 9 when moving up and down. At the same time, the cooperation between the screws 9 and the second strip hole 15 can guide the sliding plate 14, ensuring that the sliding plate 14 slides smoothly vertically and avoids getting stuck in the door frame 4.

[0031] The top of the pull rod 13 is a hook, and the swing arm 12 is rotatably connected to the hook tip. After turning the handle, the pull rod 13 moves upward, and the hook is hooked onto the rotating shaft 11.

[0032] like Figure 4 As shown, the combined weight of the lever 1, slide plate 14, and pressure block 16 acts on the brake pad 17, causing it to press against the ground 6 and locking the door 2 in place by friction. When the opening of the door 2 needs to be changed, the handle 3 is turned, causing the pivot 11 to rotate clockwise. Simultaneously, the swing arm 12 rotates clockwise around the pivot 11, pulling the lever 13 upwards, which in turn pulls the slide plate 14, pressure block 16, and brake pad 17 upwards, causing the brake pad 17 to disengage from the ground (e.g., ...). Figure 5 and Figure 6 As shown, the hook at the top of the lever 13 is attached to the pivot 11. The handle 3 can be released at this time. Because the hook is attached to the pivot 11, the brake pad 17 will not slide down under gravity. Pushing the door leaf 2 adjusts the opening degree of the door leaf 2.

[0033] Once door panel 2 reaches the desired position, turn handle 3 counterclockwise to return lever 13, slide plate 14, pressure block 16, and brake pad 17 to their original positions. Figure 4 By positioning the door leaf 2 at the indicated location, the position of door leaf 2 can be re-locked, thereby changing the opening degree of door leaf 2.

[0034] Example 3

[0035] The difference between this embodiment and Embodiment 2 is that:

[0036] A wheel frame 7 is located on the outer side of the corner bracket 5 near the skateboard 14. An auxiliary support wheel 10, made of nylon, is rotatably connected to the bottom of the wheel frame 7 and can travel along the ground 6. The wheel frame 7 has a vertical first slot 8 at a position corresponding to the screw 9, through which the screw 9 passes. The first slot 8 allows for adjustment of the installation height of the wheel frame 7 according to the distance between the door frame 4 and the ground 6.

[0037] When the width or weight of the door leaf 2 is too large, the support wheel 10 can prevent the door leaf 2 from falling due to deformation and rubbing against the ground 6, or the hinge from being damaged due to excessive force.
