Description

Technical Field

[0001] The invention relates to the technical field of off-axis doors, and in particular to an adjustable off-axis door structure. Background Art

[0002] The offset door is a specially designed revolving door, which is equipped with a sky axis and a ground axis device. The axis is set close to the door edge, so that the door can be tilted to one side when opened, thus providing more in and out space through the door opening. Due to its unique opening method, it presents a more modern design sense visually.

[0003] However, in the long-term use of the eccentric door, due to its own weight, frequent use and the influence of external environmental factors, it may be slightly displaced. In this way, the upper and lower positions of the door body are prone to lose stability, seriously affecting the opening and closing performance of the door.

[0004] In addition, during the installation and use of the off-axis door, problems such as the center of gravity of the door body being offset and the axis core being inaccurately positioned may also cause the door body to be offset or unevenly loaded, affecting its balance and normal operation. Currently, the commonly used axial device can only be roughly adjusted up and down, with limited adjustment accuracy and troublesome debugging, and cannot effectively solve these problems. Summary of the invention

[0005] In order to solve the above problems in the background technology, the present invention provides an adjustable off-axis door structure.

[0006] The solution adopted by the present invention to solve its technical problems is: an adjustable off-axis door structure, including a door frame, a door body, a circumferential axis device embedded in the top of the door body, and a terrestrial axis device embedded in the bottom of the door body, the top and bottom of the door frame are respectively embedded with a first door clamp and a second door clamp, and the first door clamp and the second door clamp both have axial holes for matching the circumferential axis device and the terrestrial axis device; the circumferential axis device includes a bearing seat fixedly embedded in the top of the door body, an axis core located in the bearing seat and capable of being plugged into the axis hole, and an adjusting mechanism located inside the bearing seat for adjusting the position of the axis core, and the adjusting mechanism includes a vertical adjustment mechanism located inside the bearing seat. and a parallel regulator; the tail end of the shaft core is slidably installed in the vertical regulator, and the vertical regulator has an up and down adjustment component fixedly connected to the shaft core, which is used to drive the shaft core to perform fine-tuning up and down along the Z-axis direction, and the parallel regulator has a long sliding hole extending along the X-axis direction, and the vertical regulator is slidably installed in the long sliding hole, and the parallel regulator also has an up and down adjustment component, which is used to drive the shaft core to perform fine-tuning left and right along the X-axis direction; the outer surface of the door body corresponding to the installation position of the axial device is provided with an external adjustment window, which is used to drive the up and down adjustment component and the left and right adjustment component.

[0007] By adopting the above technical solution, the up and down adjustment components and the left and right adjustment components can be twisted to adjust the axis core in the vertical and horizontal directions with high precision, so as to compensate for the error of the door body during installation and ensure the stability and stability of the door body during rotation. In addition, an external adjustment window is set on the outer surface of the door body, so that the height of the door body can be adjusted directly after installation without disassembling the door body accessories for debugging, which is convenient and quick.

[0008] Furthermore, the bearing seat also has a shaft sleeve inside, the tail end of the shaft core is fixedly inserted in the shaft sleeve, and the vertical adjuster has an inner cavity opening upward, the side wall of the inner cavity is fixedly provided with a sliding protrusion extending along the Z-axis direction, and the outer side wall of the shaft sleeve is provided with a sliding groove that is slidably mounted on the sliding protrusion.

[0009] By adopting the above technical solution, the sleeve as an intermediate component can protect the shaft core from wear during the adjustment process, and the guiding function of the sliding protrusion and the sliding groove enables the shaft core to maintain strict linear motion when fine-tuning up and down, reducing the position deviation caused by oblique force and improving the accuracy of door position adjustment.

[0010] Furthermore, the up and down adjustment assembly includes a first fine-tuning screw hole provided on the bottom wall of the vertical adjuster, and a fine-tuning bolt threadedly connected to the first fine-tuning screw hole, and the top end of the fine-tuning bolt is inserted into the inner cavity and fixedly abuts against the bottom of the sleeve.

[0011] By adopting the above technical solution, the user is allowed to achieve fine adjustment of the position of the sleeve (and the shaft core inside it) by rotating the fine-tuning bolt.

[0012] Furthermore, the outer wall of the parallel adjuster has a fine-tuning thread, and its left end has a second fine-tuning screw hole. The left-right adjustment assembly includes a rotation limiter threadedly connected to the fine-tuning thread and located on the right side of the vertical adjuster, and a fine-tuning screw threadedly connected to the second fine-tuning screw hole. The right end of the fine-tuning screw is fixedly abutted against the outer wall of the vertical adjuster, and the left end has a rotating pusher.

[0013] By adopting the above technical solution, the rotation limiter can be rotated clockwise to slowly move to the right along the fine-tuning thread, thereby providing enough space for the vertical adjuster to move. Then, the rotation pusher is rotated clockwise, and the fine-tuning screw is used to push the vertical adjuster and the shaft core to the right for fine-tuning. If the shaft core needs to be fine-tuned to the left, the rotation pusher and the rotation limiter can be rotated counterclockwise to fine-tune the shaft core to the left.

[0014] Furthermore, a plurality of inner adjustment windows are provided on the side of the bearing seat facing the outer adjustment window, so as to control the rotation of the rotation limiter, the rotation pusher and the fine-tuning bolt.

[0015] By adopting the above technical solution, the rotation limiter, the rotation pusher and the fine-tuning bolt can be rotationally adjusted from the inner adjustment window, thereby realizing horizontal and vertical adjustment of the shaft core.

[0016] Furthermore, a cover plate is provided at the outer adjustment window, and one side of the cover plate is hinged in the outer adjustment window.

[0017] By adopting the above technical solution, the surface of the door body can be kept beautiful and dust can be prevented from entering the interior of the door body.

[0018] Furthermore, a movable long hole is provided on the top of the bearing seat for the shaft core to extend out and move along the X-axis direction.

[0019] Furthermore, it also includes a drainage base, the door frame bottom beam is fixedly installed in the drainage base, a water collecting chamber is provided in the drainage base, and a plurality of drainage holes connected with the water collecting chamber are arranged on the end surface, and a plurality of drainage outlets connected with the water collecting chamber are equidistantly opened on the side of the drainage base located outdoors, and each of the drainage outlets has a blocking member for blocking the drainage outlet.

[0020] By adopting the above technical solution, rainwater can be effectively guided to drain away, preventing water accumulation and leakage.

[0021] In summary, the beneficial effects of the present invention are:

[0022] 1. The axial device of the present invention can accurately adjust the horizontal and vertical positions of the axis of the axial device by adding an adjustment mechanism consisting of a vertical adjuster, a horizontal adjuster, and an up-down adjustment component and a left-right adjustment component. Specifically, the vertical adjuster and the horizontal adjuster work together to fine-tune the axis in the vertical and horizontal directions, respectively, so that the door body and the door frame are aligned more accurately to avoid skewed and irregular opening.

[0023] 2. The present invention adds an external adjustment window and an internal adjustment window, so that the user can directly adjust the internal axis device of the door body without disassembling the door body structure, quickly adjust the height and horizontal position of the door body, and effectively improve the efficiency of installation and debugging. In addition, a cover plate is added at the external adjustment window to cover the adjustment window when not in use, which can not only maintain the aesthetics of the door body, but also prevent external pollution from entering the internal axis device and the door body.

[0024] 3. The present invention can effectively guide rainwater to be discharged by adding a drainage base at the bottom, prevent water accumulation and leakage, and meet the conditions for outdoor use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0036] like Figures 1 to 6 As shown, an adjustable off-axis door structure, wherein this embodiment includes a door frame 1, a door body 2, a circumferential axis device 3 embedded in the top of the door body 2, and a terrestrial axis device 4 embedded in the bottom of the door body 2, the top and bottom of the door frame 1 are respectively embedded with a first door clamp 11 and a second door clamp 12, and the first door clamp 11 and the second door clamp 12 both have an axis hole 13 for matching the circumferential axis device 3 and the terrestrial axis device 4; the circumferential axis device 3 includes a bearing seat 31 fixedly embedded in the top of the door body 2, an axis core 32 located in the bearing seat 31 and capable of being plugged into the axis hole 13, and an adjusting mechanism 33 located inside the bearing seat 31 for adjusting the position of the axis core 32, and the adjusting mechanism 33 includes a vertical adjuster 331 located inside the bearing seat 31 and a parallel adjuster The rear end of the shaft core 32 is slidably installed in the vertical adjuster 331, and the vertical adjuster 331 has an up and down adjustment component 34 fixedly connected to the shaft core 32, which is used to drive the shaft core 32 to perform fine-tuning up and down along the Z-axis direction, and the parallel adjuster 332 has a long sliding hole 3321 extending along the X-axis direction, and the vertical adjuster 331 is slidably installed in the long sliding hole 3321, and the parallel adjuster 332 also has an up and down adjustment component 34, which is used to drive the shaft core 32 to perform fine-tuning left and right along the X-axis direction; the outer surface of the door body 2 corresponding to the installation position of the axial device 3 is provided with an external adjustment window 21, which is used to drive the up and down adjustment component 34 and the left and right adjustment component 35.

[0037] The eccentric door structure of this embodiment includes a door frame 1 and a door body 2 portion installed inside the door frame 1, or only includes the door body 2 portion. The door body 2 portion can be a single door body 2, or a door body 2 structure with a door leaf. In this embodiment, the top and bottom of the door frame 1 and the door body 2 are provided with an installation cavity that is offset from the center position. The first door clamp 11 and the second door clamp 12 are embedded in the installation cavity of the door frame 1, and the sky axis device 3 and the ground axis device 4 are embedded in the installation cavity at the corresponding position of the door body 2, and all components are fixed and installed by screws. Specifically, the sky axis device 3 of this embodiment is composed of a bearing seat 31, an axis core 32 and an adjustment mechanism 33. The bearing seat 31 is fixedly embedded in the installation cavity of the door body 2 as a supporting shell, and a cavity is provided inside it. The axis core 32 is vertically installed in the cavity, and the axis core 32 can be plugged into the axis hole 13 of the first door clamp 11 and adjusted by the adjustment mechanism 33. The adjustment mechanism 33 includes a vertical adjuster 331 and a parallel adjuster 332 , which are used to adjust the vertical and horizontal positions of the shaft core 32 respectively, so as to achieve precise adjustment of the shaft core 32 .

[0038] The vertical adjuster 331 contains a vertical sliding cavity 3331, one end of the shaft core 32 is inserted into the shaft hole 13, and the other end is slidably installed in the sliding cavity 3331. At the tail end of the vertical adjuster 331, an up-down adjustment component 34 is provided, which has an operable part for driving the shaft core 32 to perform fine adjustment along the sliding cavity 3331 inside the vertical adjuster 331, i.e., in the Z-axis (i.e., in the vertical direction), so as to adjust the height of the door body 2. This function can effectively compensate for the minor errors that may occur in the door frame 1 or the door body 2 during the installation process, and ensure the stability and stability of the door body 2 during rotation. As for the parallel adjuster 332, a sliding long hole 3321 extending along the X-axis direction is provided inside, allowing the vertical adjuster 331 to move in the horizontal direction as a whole. A guide structure, such as a guide rail or a guide groove, is also provided in the sliding long hole 3321 to ensure that the vertical adjuster 331 can only move along a predetermined path to avoid unnecessary lateral displacement. In addition, the parallel adjuster 332 is also equipped with a left-right adjustment component 35, which is used to push or pull the vertical adjuster 331, and is used to drive the shaft core 32 to move along the X-axis direction to perform left-right fine adjustment. When there is a horizontal deviation between the door body 2 and the door frame 1 during the installation process, the left-right adjustment can compensate for this deviation, so that the door body 2 can be more accurately aligned with the door frame 1, thereby ensuring the balance of the door body 2 when rotating, and avoiding irregular deflection when the door body 2 is rotated and opened.

[0039] In addition, an external adjustment window 21 is provided at the portion where the outer surface of the door body 2 is connected to the axis device 3 (i.e., the installation position of the axis device 3), through which the axis device 3 in the installation cavity of the door body 2 can be conveniently adjusted. Specifically, by operating the up and down adjustment components 34, the axis core 32 can be adjusted in the Z-axis direction (vertical direction); and by operating the left and right adjustment components 35, the axis core 32 can be fine-tuned in the X-axis direction (horizontal direction). After the door body 2 is installed, the axis device 3 can directly adjust the height of the door leaf, and the horizontal and vertical directions can be debugged without disassembling the door body 2 structure, which is simple and quick to operate.

[0040] like Figure 3 and Figure 4 As shown, the bearing seat 31 of this embodiment also has a sleeve 36 inside, the tail end of the shaft core 32 is fixedly inserted in the sleeve 36, and the vertical adjuster 331 has an inner cavity 3331 that opens upward, the side wall of the inner cavity 3331 is fixedly provided with a sliding protrusion 3332 extending along the Z axis direction, and the outer wall of the sleeve 36 is provided with a sliding groove 3333 that is slidably mounted on the sliding protrusion 3332. Specifically, the sleeve 36 is arranged inside the bearing seat 31, the outer shell of the sleeve 36 is square, and the tail end of the shaft core 32 is fixedly inserted in the sleeve 36. The side wall of the inner cavity 3331 in the vertical adjuster 331 is fixedly provided with a sliding protrusion 3332 extending along the Z axis direction, and the outer wall of the sleeve 36 is provided with a sliding groove 3333 matching therewith. The sleeve 36 (and then the shaft core 32) is guided and positioned in the inner cavity 3331 of the vertical adjuster 331. The cooperation between the sliding protrusion 3332 and the sliding groove 3333 enables the shaft core 32 to move up and down only along the Z-axis direction, thereby avoiding unnecessary lateral displacement and ensuring straightness and accuracy during the adjustment process.

[0041] like Figure 3 and Figure 4As shown, the up-down adjustment component 34 of this embodiment includes a first fine-tuning screw hole 341 provided on the bottom wall of the vertical adjuster 331, a fine-tuning bolt 342 threadedly connected to the first fine-tuning screw hole 341, and the top end of the fine-tuning bolt 342 is inserted into the inner cavity 3331 and fixedly abuts against the bottom of the sleeve 36. Specifically, a first fine-tuning screw hole 341 penetrating the inner cavity 3331 is provided on the bottom wall of the vertical adjuster 331, and the fine-tuning bolt 342 is installed by threaded connection. The nut part of the bolt is designed as a hexagonal hole, which is convenient for the user to use an L-shaped wrench to extend into the installation cavity through the outer adjustment window 21, and rotate the bolt to accurately adjust the position of the sleeve 36 and its internal shaft core 32. When the fine-tuning bolt 342 is rotated, the bolt will slowly move along the direction of the screw hole, thereby pushing or pulling the sleeve 36, and the precision adjustment can reach 0.1 mm or even smaller, so as to achieve the up-down fine-tuning of the shaft core 32 along the Z-axis direction. The user can finely adjust the position of the shaft core 32 simply by tightening or loosening the fine-tuning bolt 342 , which is convenient to operate.

[0042] like Figure 3 and Figure 4 As shown, the outer wall of the parallel adjuster 332 of this embodiment has a fine-tuning thread 3322, and the left end thereof has a second fine-tuning screw hole 3323. The left-right adjustment assembly 35 includes a rotation stopper 351 threadedly connected to the fine-tuning thread 3322 and located on the right side of the vertical adjuster 331, and a fine-tuning screw rod 352 threadedly connected to the second fine-tuning screw hole 3323. The right end of the fine-tuning screw rod 352 is fixedly abutted against the outer wall of the vertical adjuster 331, and the left end thereof has a rotation pusher 353. Specifically, the fine-tuning thread 3322 is provided on the outer wall of the shell of the parallel adjuster 332, which is used to be threadedly connected to the rotation stopper 351 of the left-right adjustment assembly 35, and the rotation stopper 351 is placed on the right side of the vertical adjuster 331. A second fine-tuning screw hole 3323 is provided on the left end face of the parallel adjuster 332, and a fine-tuning screw 352 is threadedly connected and installed inside the screw hole, the right end of which is fixedly abutted against the left outer wall of the vertical adjuster 331, and the left end has a rotating pusher 353, and the outer sides of the rotating pusher 353 and the rotating stopper 351 are both provided with anti-slip lines, which are convenient for users to perform rotation adjustment. When the shaft core 32 needs to be adjusted in the horizontal direction, the rotating stopper 351 is first turned clockwise to slowly advance to the right along the fine-tuning thread 3322, so as to make room for the vertical adjuster 331 to move, and then the rotating pusher is twisted clockwise to push the vertical adjuster 331 to move to the right for fine-tuning through the fine-tuning screw 352. Similarly, the pusher 353 can be twisted counterclockwise to use the fine-tuning screw 352 to pull the vertical adjuster 331 to move to the left for fine-tuning, and then the limiting member 351 can be twisted counterclockwise to make it move to the left progressively to limit the vertical adjuster 331.

[0043] like Figure 2As shown, the bearing seat 31 of this embodiment is provided with a plurality of inner adjustment windows 37 on the side facing the outer adjustment window 21, which are used to control the rotation of the rotation limiter 351, the rotation pusher 353 and the fine adjustment bolt 342. Specifically, a plurality of inner adjustment windows 37 are provided on the side wall of the bearing seat 31 on the side facing the outer adjustment window 21, respectively corresponding to the rotation limiter 351, the rotation pusher 353 and the fine adjustment bolt 342, so as to facilitate the rotation adjustment of the above components.

[0044] like Figure 2 As shown, a cover plate 22 is provided at the outer adjustment window 21 of this embodiment, and one side of the cover plate 22 is hinged inside the outer adjustment window 21. One side of the cover plate 22 is installed inside the outer adjustment window 21 through a hidden hinge or other hinged parts. The user only needs to gently open the cover plate 22 to perform the adjustment operation without removing any parts, and the operation is simple and quick. In the closed state, the cover plate 22 can completely cover the inner adjustment window 37, keep the surface of the door body 2 flat and smooth, improve the overall aesthetics, and will not affect the design style of the door body 2. In addition, the cover plate 22 can effectively prevent external impurities such as dust and moisture from entering the adjustment window, protect the internal mechanical parts from pollution and corrosion, and thus extend the service life.

[0045] Furthermore, a movable long hole 38 is provided at the top of the bearing seat 31 of the present embodiment for the shaft core 32 to extend and move along the X-axis direction. Specifically, a movable long hole 38 is transversely provided at the top of the bearing seat 31, and the long hole has a length for the shaft core 32 to move, and its width is equal to the diameter of the shaft core 32, thereby preventing the shaft core 32 from unnecessary lateral displacement during the left and right movement.

[0046] like Figure 6 As shown, the eccentric door structure of this embodiment also includes a drainage base 5, and the bottom beam of the door frame 1 is fixedly installed in the drainage base 5. A water collecting chamber 51 is provided in the drainage base 5, and a plurality of drain holes 52 connected to the water collecting chamber 51 are arranged on the end surface. A plurality of drain ports 53 connected to the water collecting chamber 51 are equidistantly opened on the side of the drainage base 5 located outdoors, and each drain port 53 has a plugging member for blocking the drain port 53. Since the bottom beam of the door frame 1 is closely combined with the drainage base 5, the possibility of rainwater infiltrating into the room from the bottom of the door frame 1 is reduced. The drain holes 52 evenly arranged on the drainage base 5 can quickly flow the collected water into the water collecting chamber 51, so that the rainwater can be collected in a centralized manner instead of being retained around the door frame 1. And by opening a plurality of drain ports 53 on the side of the drainage base 5 located outdoors, all of which are connected to the above-mentioned water collecting chamber 51, the water flow can be diverted to the outdoors in a timely manner to meet the outdoor use scenario. A removable plugging piece is provided in the drain port 53 so as to close the drain port 53 when not needed.

[0047] In summary, the beneficial effects of this embodiment are as follows: the eccentric door structure of this embodiment can accurately adjust the horizontal and vertical positions of the door body 2 through the adjustment mechanism 33 of the zenith device 3. Through the vertical adjuster 331 and the horizontal adjuster, the installation position of the door body 2 can compensate for errors during the installation process to ensure the stability and stability of the door body 2 when rotating. Specifically, the vertical adjuster 331 and the horizontal adjuster work together to fine-tune the Z axis (vertical direction) and X axis (horizontal direction) of the shaft core 32, respectively, so that the door body 2 is aligned with the door frame 1 more accurately to avoid skew and irregular opening. The design of the outer adjustment window 21 and the inner adjustment window 37 enables the user to make adjustments directly without disassembling the structure of the door body 2. The user can operate the up and down adjustment component 34 and the left and right adjustment component 35 through the outer adjustment window 21 to quickly adjust the height and horizontal position of the door body 2, greatly improving the installation and debugging efficiency. In addition, the cover plate 22 is designed to cover the adjustment window when not in use, which not only improves the aesthetics, but also prevents external pollution from entering the adjustment system. In addition, this embodiment adopts the design of fine-tuning bolts 342 and fine-tuning screw holes, so that each adjustment action can achieve high-precision fine-tuning, and the adjustment range can reach 0.1 mm or even smaller. Especially for slight deviations in the vertical height and horizontal position of the door body 2, the stability of the door body 2 during rotation can be ensured through fine adjustment.
