Description

Technical Field

[0001] The utility model relates to the technical field of door shafts, and in particular to an adjustable door shaft structure and a door with an adjustable door gap. Background Art

[0002] At present, door leaves are usually installed on door frames using door shafts with fixed structures. Due to errors in the processing and installation process, it is often difficult for the door leaves to maintain a good seal with the door frame when closed, and there is a large gap between the door leaves and the door seam or friction occurs. In addition, during use, the door leaves may be deformed or offset due to their own weight or long-term use, resulting in an increase in the door seam or a decrease in the gap between the door leaves and the door frame, thereby generating friction noise. The current door shaft structure has a single function and cannot adjust the installation position of the door shaft, which is not convenient for the installation of the door leaves. In the later stage, the door leaves cannot be adjusted after being offset, tilted, or the door seam increases, resulting in noise when opening and closing the door, poor sound insulation and heat insulation due to large door seams, and the inability to open and close the door smoothly.

[0027] First embodiment

[0028] Please refer to Figure 1 and Figure 4 The present embodiment provides an adjustable door axis structure, which includes a door axis seat 1, a door axis rod 2, and a transverse adjustment rod 3. The door axis seat 1 is provided with an adjustment cavity 101 and a first slot 102 connected to the adjustment cavity 101. The door axis rod 2 is arranged in the adjustment cavity 101, and the transverse adjustment rod 3 is movably arranged in the first slot 102. The transverse adjustment rod 3 is drivingly connected to the door axis rod 2, and the transverse adjustment rod 3 is driven to drive the door axis rod 2 to move in a direction perpendicular to the axis of the door axis rod 2.

[0029] In this embodiment, an adjustment cavity 101 for accommodating the door shaft rod 2 is provided inside the door shaft seat 1, and the door shaft rod 2 is movably arranged in the adjustment cavity 101, and the door shaft rod 2 can move freely inside the adjustment cavity 101. A first clamping groove 102 connected to the adjustment cavity 101 is provided on the door shaft seat 1, and is used to install the transverse adjustment rod 3. One end of the transverse adjustment rod 3 is arranged in the first clamping groove 102, and is driven and connected to the door shaft rod 2 in the adjustment cavity 101 through the first clamping groove 102. The transverse position of the door shaft rod 2 can be moved by driving the transverse adjustment rod 3.

[0030] When in use, the door shaft seat 1 is connected to the door leaf, and then a mounting groove is opened on the door frame, and finally the door shaft rod 2 is rotated and set in the mounting groove. After installation, the door shaft rod 2 is driven to move laterally relative to the door shaft seat 1 by the lateral adjustment rod 3. At this time, since the door shaft rod 2 is rotatably installed on the door frame, the door shaft rod 2 does not move laterally, but the door shaft seat 1 is displaced laterally relative to the door frame, and drives the door leaf connected to the door shaft seat 1 to move laterally, thereby changing the door gap on the left and right sides of the door leaf, and avoiding the door gap on one side being too small, resulting in unsmooth door opening and closing or noise.

[0031] Please refer to Figure 1 and Figure 2Furthermore, in this embodiment, the adjustable door axis structure also includes a longitudinal adjustment rod 4, and a second card slot 103 connected to the adjustment cavity 101 is opened on the door axis seat 1, and the extension directions of the first card slot 102 and the second card slot 103 are perpendicular to each other. The transverse adjustment rod 3 can slide along the extension direction of the first card slot 102, and the longitudinal adjustment rod 4 is slidably clamped in the second card slot 103 along the extension direction of the second card slot 103, and the longitudinal adjustment rod 4 is drivingly connected to the door axis rod 2, and is used to adjust the longitudinal height of the door axis rod 2 along the axial direction of the door axis rod 2.

[0032] The longitudinal adjustment rod 4 has the same working principle as the transverse adjustment rod 3. The longitudinal adjustment rod 4 adjusts the longitudinal height of the door shaft rod 2 after being driven externally. Specifically, the door shaft seat 1 is provided with a first card slot 102 and a second card slot 103 which are connected to the adjustment cavity 101. The first card slot 102 and the second card slot 103 are both bar slots and are perpendicular to each other. The transverse adjustment rod 3 is slidably arranged in the first card slot 102 and can slide up and down along the first card slot 102. The longitudinal adjustment rod 4 is slidably arranged in the second card slot 103 and can slide laterally along the second card slot 103. When the transverse adjustment rod 3 is driven to drive the door shaft rod 2 to move laterally, the longitudinal adjustment rod 4 which is driven and connected to the door shaft rod 2 moves laterally synchronously along the second card slot 103 and the door shaft rod 2. Conversely, when the longitudinal adjustment rod 4 is driven to drive the door shaft rod 2 to move up and down, the transverse adjustment rod 3 connected to the door shaft rod 2 moves longitudinally synchronously along the second card slot 103. When the lateral adjustment rod 3 and the longitudinal adjustment rod 4 are not driven, the lateral adjustment rod 3 and the longitudinal adjustment rod 4 form a locking effect with each other to ensure that the door shaft rod 2 will not be displaced during use. In this embodiment, the lateral adjustment rod 3 and the longitudinal adjustment rod 4 can be driven separately, that is, the lateral adjustment rod 3 can be driven separately to adjust the left and right door gaps or the longitudinal adjustment rod 4 can be driven to adjust the upper and lower door gaps. The two adjustment methods are independent of each other and easy to operate. Since the door shaft rod 2 is connected to the door frame and the door shaft seat 1 is connected to the door leaf, the door shaft rod 2 can be adjusted during use. Therefore, when installing the door leaf, the door shaft position can be adjusted first according to the actual situation, and then the door leaf can be installed. The door shaft can also be adjusted after the door leaf is installed to adjust the door leaf to a suitable position, which is easy to operate. During use, the door leaf may be deformed or displaced due to long-term use, resulting in changes in the upper, lower, left and right door gaps of the door leaf. At this time, the door leaf is invalidly disassembled, and the door leaf can be adjusted to a suitable position by adjusting the lateral adjustment rod 3 and the longitudinal adjustment rod 4 respectively, which is easy to operate.

[0033] Please refer to Figure 1 and Figure 3 Furthermore, in some implementations of the present embodiment, a longitudinal screw hole 201 is provided at one end of the door shaft rod 2, a transverse screw hole 202 is provided on the side wall of the door shaft rod 2, the transverse adjustment rod 3 is threadedly connected to the door shaft rod 2 via the transverse screw hole 202, and the longitudinal adjustment rod 4 is threadedly connected to the door shaft rod 2 via the longitudinal screw hole 201.

[0034] The door shaft rod 2 is threadedly connected with the lateral adjustment rod 3 and the longitudinal adjustment rod 4, and the lateral adjustment rod 3 or the longitudinal adjustment rod 4 can be rotated forward or backward. The lateral position or longitudinal height of the door shaft rod 2 can be adjusted by the threaded cooperation between the lateral adjustment rod 3 and the longitudinal adjustment rod 4 and the door shaft rod 2. The structure is simple and the adjustment is convenient. When adjusting, the displacement distance can be accurately adjusted according to the number of rotations or the rotation angle, and the door leaf can be adjusted to a suitable position. It can be understood that the door gap around the door leaf is narrow, and usually only a small distance needs to be moved when adjusting.

[0035] Optionally, in some other embodiments, the transverse adjustment rod 3 and the longitudinal adjustment rod 4 can be connected to the door shaft rod 2 via a latch. Specifically, the transverse adjustment rod 3 and the longitudinal connecting rod are evenly spaced and provided with a plurality of adjustment holes at one end close to the door shaft rod 2, and a corresponding connection hole is provided on the door shaft rod 2. When the transverse position of the door leaf needs to be adjusted, the operator manually moves the transverse adjustment rod 3 and drives the door leaf connected to the door shaft seat 1 to move to a suitable position, and then aligns the adjustment hole on the transverse adjustment rod 3 closest to the connection hole with the connection hole on the door shaft rod 2, and inserts the fixing latch. When adjustment is required again, remove the fixing latch and repeat the above steps. Similarly, when adjusting the longitudinal height of the door leaf, move the longitudinal adjustment rod 4 up and down so that the adjustment hole of the corresponding height is aligned with the connection hole on the door shaft rod 2 and the fixing latch is inserted.

[0036] Furthermore, in some implementations of this embodiment, the first card slot 102 and the second card slot 103 are both T-shaped structures.

[0037] Correspondingly, the ends of the transverse adjustment rod 3 and the longitudinal adjustment rod 4 away from the door shaft rod 2 are both set to a T-shaped structure that matches the shape of the first slot 102 and the second slot 103. The first slot 102 is opened in the vertical direction. When the T-shaped structure of the transverse slot is clamped in the first slot 102, the transverse adjustment rod 3 can be stably clamped in the T-shaped first slot 102. At this time, the transverse adjustment rod 3 can only move along the first slot 102 in the vertical direction, and will not be displaced or tilted horizontally, so as to avoid the transverse adjustment rod 3 shaking or tilting horizontally during use, resulting in unstable door leaf connection, noise or failure to open and close normally. Similarly, the second slot 103 is opened horizontally along the door shaft seat 1. When the longitudinal adjustment rod 4 is clamped in the second slot 103, the longitudinal adjustment rod 4 moves horizontally in the second slot 103, and will not be displaced or tilted longitudinally, so as to avoid the door leaf from tilting.

[0038] Furthermore, in some implementations of the present embodiment, an adjustment portion is provided at one end of the lateral adjustment rod 3 and the longitudinal adjustment rod 4 away from the door shaft rod 2, and the adjustment portion is used to cooperate with an external adjustment tool.

[0039] The adjustment part can be an external hexagon bolt for connecting external wrenches and other tools. A connection groove in the shape of an internal hexagon or a cross can also be provided at one end of the adjustment rod, and a screw of a corresponding shape can be used to rotate and adjust the lateral adjustment rod 3 or the longitudinal adjustment rod 4. It can be understood that when adjusting the door leaf after installation, the lateral adjustment rod 3 or the longitudinal adjustment rod 4 is very inconvenient due to the weight of the door leaf and the obstruction of the door frame and the door leaf. At this time, the adjustment is made by connecting the adjustment part with an external tool, which is convenient for operation and can save effort. No professional operator is required, and the user can perform the adjustment operation by himself.

[0040] Please refer to Figure 3 Furthermore, in some implementations of the present embodiment, a transverse adjustment hole 104 and a longitudinal adjustment hole 105 are respectively opened on the door shaft seat 1, the transverse adjustment hole 104 is connected to the first slot 102, and the longitudinal adjustment hole 105 is connected to the second slot 103.

[0041] The transverse adjustment hole 104 is connected to the first slot 102. The function of the transverse adjustment hole 104 is to expose the adjustment part in the first slot 102, so that the operator can connect and cooperate with the adjustment part of the transverse adjustment rod 3 with an external adjustment tool such as a screwdriver. Similarly, the longitudinal adjustment hole 105 is connected to the second slot 103, and the external adjustment tool can be connected to the longitudinal adjustment rod 4 in the second slot 103 through the longitudinal adjustment hole 105, so as to perform the adjustment operation.

[0042] Furthermore, the transverse adjustment hole 104 and the longitudinal adjustment hole 105 are both bar-shaped holes. The transverse adjustment hole 104 is parallel to the direction of the first card slot 102 , and the longitudinal adjustment hole 105 is parallel to the direction of the second card slot 103 .

[0043] It can be understood that when the door shaft rod 2 is adjusted laterally, the longitudinal adjustment rod 4 connected to the door shaft rod will move laterally in the second slot 103 along with the movement of the door shaft rod 2. Conversely, when the longitudinal height of the door shaft rod 2 is adjusted, the transverse adjustment rod 3 will move longitudinally in the first slot 102 along with the movement of the door shaft rod 2. Therefore, the transverse adjustment hole 104 and the longitudinal adjustment hole 105 are configured as strip holes arranged parallel to the first slot 102 or the second slot 103, and even if the transverse adjustment rod 3 or the longitudinal adjustment rod 4 moves during the adjustment process, the adjustment portion will be fully exposed in the strip adjustment hole, so as to avoid the door shaft seat 1 blocking the adjustment portion of the transverse adjustment rod 3 or the longitudinal rod, and preventing external tools from connecting with the transverse adjustment rod 3 or the longitudinal adjustment rod 4.

[0044] Furthermore, in some implementations of this embodiment, a mounting hole 106 is provided on the door shaft seat 1.

[0045] Optionally, the door shaft seat 1 is provided with a plurality of mounting holes 106, and studs or screws can be passed through the mounting holes 106. The door shaft seat 1 is connected to the door leaf through the mounting holes 106, and the plurality of connecting holes are provided to improve the connection strength of the door shaft seat 1 when connected, and to improve the stability of the door leaf when in use.

[0046] Furthermore, in some implementations of the present embodiment, a mounting protrusion 5 is provided at one end of the door axis rod 2 away from the door axis seat 1, and the mounting protrusion 5 is rotatably connected to the external door frame.

[0047] Specifically, the lower end surface of the mounting protrusion 5 abuts against the door frame, and the door shaft rod 2 is supported by the mounting protrusion 5, which is convenient for installing the door shaft rod 2. It can be understood that to achieve the height adjustment of the door shaft rod 2, one end of the door shaft rod 2 connected to the door frame must abut against the door frame, and the door shaft rod 2 can rotate freely. When the door shaft rod 2 rotates, the end of the door shaft rod 2 is prone to large wear due to friction, which may cause the door shaft rod 2 to shorten or the opening on the door frame for connecting the door shaft rod 2 to deepen. At the same time, in order to ensure that the door shaft can abut against the door frame, it is necessary to open a hole of appropriate depth on the door frame for installing the door shaft rod 2. If the opening is too deep, the longitudinal height adjustment effect of the door shaft rod 2 is poor, and in severe cases, the door shaft rod 2 may not be installed normally. Therefore, the mounting protrusion 5 is provided on the door shaft rod 2 to increase the contact area between the door shaft rod 2 and the door frame, reduce the pressure, and thus reduce wear. On the other hand, supporting the door leaf by the mounting protrusion 5 is also more stable and can be used for the installation of various rotating door leaves. After installation, the height of the mounting protrusion 5 to the door shaft seat 1 corresponds to the width of the door gap. During adjustment, the length of the door shaft rod 2 can be visually observed, which facilitates the installation of the door leaf.

[0048] Furthermore, the mounting protrusion 5 is a disc-shaped structure, which increases the supporting surface, improves the stability during rotation, and avoids shaking during the opening and closing process of the door leaf.

[0049] Optionally, in some other embodiments, a placement groove adapted to the installation protrusion 5 may be opened on the external door frame to further improve the stability of the door shaft rod 2 after installation.

[0050] Optionally, in some implementations of the present embodiment, the door shaft rod 2 and the mounting protrusion 5 are integrally formed. The integral forming can improve the connection strength between the mounting protrusion 5 and the door shaft rod 2, and ensure the stability and safety of the door shaft rod 2. It can be understood that in order to ensure the rotation and opening and closing of the door leaf, the door leaf is only connected to the door frame by the door shaft rod 2, and the support strength of the door shaft rod 2 is required to be relatively high. The door shaft rod 2 and the mounting protrusion 5 are integrally formed, and the connection strength is higher, which avoids the damage of the mounting protrusion 5 during the use of the door leaf, resulting in the breakage of the door shaft rod 2 or the loss of the supporting function, causing a safety accident, and improves the safety and service life of the door shaft rod 2 during use.

[0051] Second embodiment

[0052] The present embodiment provides a door with an adjustable door gap, which includes any of the above-mentioned adjustable door shaft structures as well as a door frame and a door leaf, wherein the door leaf is rotatably connected to the door frame via the adjustable door shaft structure.

[0053] In this embodiment, the door leaf is connected to the door frame through any adjustable door axis structure provided in the above-mentioned embodiment 1. Specifically, the door axis seat 1 is fixedly connected to the door leaf by bolts or screws, and an adjustable door axis structure is respectively provided at the upper and lower ends of the door leaf, thereby forming two rotation connection points, ensuring that a stable rotation axis is formed when connected to the door frame. The door frame is correspondingly provided with an opening for connecting the door axis stem, and the door axis rod 2 is inserted into the opening and rotatably connected to the door frame to realize the use function of rotating opening and closing of the door leaf. During use, the lateral or longitudinal position of the door axis rod 2 at the upper and lower ends is adjusted respectively, so as to adjust the door gap on the upper, lower, left and right of the door leaf, so as to avoid the gap between the door leaf and the door frame being too small to affect the normal opening and closing of the door leaf or to generate harsh noise or damage the door frame due to friction. Thereby, the door leaf is ensured to open and close smoothly without generating noise.

[0054] In summary, the utility model provides an adjustable door axis structure, which includes a door axis seat 1, a door axis rod 2, and a transverse adjustment rod 3. The door axis seat 1 is provided with an adjustment cavity 101 and a first clamping groove 102 connected with the adjustment cavity 101. The door axis rod 2 is arranged in the adjustment cavity 101. The transverse adjustment rod 3 is movably clamped in the first clamping groove 102. The transverse adjustment rod 3 is drivingly connected to the door axis rod 2. The transverse adjustment rod 3 is driven to drive the door axis rod 2 to move in a direction perpendicular to the axis of the door axis rod 2. By providing the transverse adjustment rod 3 in conjunction with the door axis seat 1 provided with a special slide groove, the effect of independently adjusting the transverse position of the door axis rod 2 is achieved, and the door axis position can be adjusted after the door leaf is installed and during the use of the door leaf, which is convenient for installation and operation.

[0055] The present invention also provides a door with an adjustable door gap, wherein the door leaf adopts the above-mentioned adjustable door axis structure, and the lateral position and longitudinal height of the door axis can be adjusted, thereby changing the size of the door gap in the upper, lower, left and right directions of the door leaf, improving the smoothness of the door leaf when opening and closing, and reducing friction noise during use.
