Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door leaf structure, and in particular to a door leaf structure capable of being adjusted based on door panel deformation prevention. BACKGROUND

[0002] A door leaf is a component of furniture and doors, which can be opened and closed left and right, and is usually made of wood. After being manufactured and leaving the factory, the door leaf is prone to bending deformation due to logistics transportation or stacking. The current industry generally adopts the following specific solutions to adjust the bent door leaf: 1) increasing the number of door leaf hinges and adding steel joists to solve the bending deformation of the door leaf, and correcting the bent door leaf during production and installation; 2) removing the door leaf on site using a fulcrum, applying external force to straighten the door leaf, and then installing it, which takes a long time to correct and cannot correct the door panel deformation in time. The door leaf with severe deformation must be re-made or returned to the factory for repair.

[0003] A door panel with a patent number CN202022445867.1 is proposed in the prior art, which mills a groove on the inner side of the cabinet door panel at 1 / 3 of the lock, with a length consistent with the height of the cabinet door. Then, the straightener is half-convexly installed in the groove, and the convex assembly occupies the inner side of the flat space and affects the aesthetics of the inner side. The groove on the inner side of the cabinet door panel damages the overall structure and rigidity, and easily causes deformation or even breakage of the cabinet door in the width direction. The advantage of this scheme is that the bending of the cabinet door panel can be quickly corrected on site, but it still has the following disadvantages: 1) high production cost, requiring the production of special profile production molds, and complex production process; 2) damaging the symmetry of the product structure, easily causing product transverse deformation or even door panel breakage and being unable to handle; 3) only applicable to thin cabinet door products.

[0004] Therefore, based on the above problems, a new adjustable structure based on door leaf deformation prevention is needed to improve the door leaf structure. SUMMARY

[0005] The present application aims to provide a door leaf structure capable of being adjusted based on door panel deformation prevention, which can solve one of the above problems.

[0008] It should be noted that in the prior art, a straightener is usually used to straighten and correct the deformed door panel, but when the straightener is used for correction, a groove needs to be milled on the door panel to install the straightener, which will damage the structural strength of the door panel, and the straightening force of the straightener is small, and it is difficult to completely correct the deformed door panel. Therefore, the adjusting mechanism is arranged in the door leaf skeleton frame to correct the deformed door panel through the adjusting mechanism. Specifically, when the door panel is warped, the adjusting rod is rotated to drive the threaded lead screw to rotate, so that the adjusting block on the surface of the threaded lead screw moves outside, the distance between the adjusting block and the positioning block is changed, the adjusting block and the positioning block are pulled tightly, the adjusting block and the positioning block respectively exert a pulling force on the upper and lower ends of the door leaf, the bending deformation of the door panel is corrected, the door panel deformation problem is effectively solved, the damage to the structural strength of the door panel is avoided, and the overall strength of the door leaf is ensured.

Through the above fastening connector structure, the door plate can be pulled without hindering the movement of the positioning block, so as to correct and straighten the door plate after bending deformation, and at the same time, the connection strength of the door plate with the positioning block and the adjusting block is enhanced, the adjusting block and the positioning block are prevented from falling off during the straightening and adjustment of the door plate, and thus the strength of the adjusting mechanism is ensured to ensure normal work.

[0011] More preferably, an auxiliary fixing part is further arranged on the convex ring part, the auxiliary fixing part comprises an inflation cavity, a piston push rod, a groove, an expansion air bag and a deformation plate, the inflation cavity is arranged along the axial direction of the nail body part and is arranged in the inside of the convex ring part in a circumferential array, the piston push rod is arranged in the inflation cavity and abuts against one end of the second wedge-shaped block, the groove is arranged on the outer ring surface of the convex ring part and corresponds to the inflation cavity one by one, the expansion air bag is embedded in the groove and is in communication with the inflation cavity through a communication pipe, and the deformation plate is arranged at the opening of the groove, is used for plugging the groove, and the lower plate surface thereof is in contact with the expansion air bag.

[0015] Preferably, a power device for rotating the adjusting rod is arranged in the door leaf skeleton frame, and the power device and the laser distance measuring sensor are signal connected through a central control unit integrated in the door leaf skeleton frame. By arranging the power device, the distance change between the calibration plate and the laser distance measuring sensor can be measured by the laser distance measuring sensor, and the deformation direction of the door panel can be identified, so as to help start the corresponding power device to drive the adjusting rod to rotate, and then adjust and correct the deformed door leaf.

It should be noted that the present application has been in the actual research and development stage.

[0031] Example 1

[0032] Please refer to Figures 1 to 5As shown, the embodiment discloses a kind of adjustable door leaf structure based on the deformation prevention of door panel 2, including door leaf skeleton frame 1 and door panel 2, and adjusting mechanism 3 in door leaf skeleton frame 1, it needs to be explained here, to ensure the symmetry of door leaf product, and ensure its structural strength, when specific implementation, adjusting structure is provided with at least two groups, and symmetrically arranged with each other;Any adjusting mechanism 3 includes outer frame 30 and two adjusting components 31, the length direction of outer frame 30 is parallel with the length direction of door leaf skeleton frame 1, two adjusting components 31 are parallelly arranged in outer frame 30, and the vertical projection of two adjusting components 31 coincides with each other, that is, two adjusting components 31 are located at the front of door leaf and the back of door leaf respectively;Any adjusting component 31 includes: adjusting rod 310, positioning block 311 and adjusting block 312, adjusting rod 310 is parallelly arranged in outer frame 30, and one end is fixedly connected with threaded lead screw 3100, and the bottom end of threaded lead screw 3100 is rotatably connected with outer frame 30 by bearing piece, positioning block 311 is fixedly sleeved on the outer part of adjusting rod 310 away from threaded lead screw 3100, adjusting block 312 is sleeved on the outside of threaded lead screw 3100 and threadedly cooperates with it, the two sides of adjusting block 312 are slidingly matched with outer frame 30, and adjusting block 312 and positioning block 311 are fixedly connected with corresponding door panel 2 respectively.

[0034] Based on the above embodiment, it needs to be supplemented that, in order to facilitate the deformation correction of the door plate 2 by the adjusting block 312 and the positioning block 311, a preferred embodiment is proposed, the door plate 2 is respectively installed at the front and back of the door leaf skeleton frame 1, and the two door plates 2 are fixedly connected with the positioning block 311 and the adjusting block 312 through the fastening connecting piece 20. Based on the above structure, when the door plate after warping deformation is pulled and adjusted by the mutual cooperation of the adjusting block 312 and the positioning block 311, on the one hand, the correction pulling force between the adjusting block and the positioning block and the door plate is ensured, and on the other hand, the connection strength therebetween is improved, which is helpful to the correction and straightening of the deformed door plate.

[0035] Based on the above embodiment, in order to further ensure the connection strength between the adjusting block 312, the positioning block 311 and the door plate 2, a preferred embodiment of the fastening connecting piece 20 is described herein, which comprises a fastening connecting piece and a connecting piece. Figure 3 The fastening connecting piece 20 comprises a fastening connecting piece and a connecting piece; wherein the fastening piece comprises: a mounting hole 200, a connecting plate 211 and a fixing nail 210, the mounting hole 200 is overall in the shape of a stepped hole, and is provided on the door plate 2 and is divided into a small-diameter section and a large-diameter section from the inside of the door plate 2 to the outside, one end of the large-diameter section forms an opening with the door plate 2, a first wedge-shaped part 201 is arranged at the inside of the large-diameter section and close to the opening position thereof, and the height of the wedge surface of the first wedge-shaped part 201 gradually decreases from the inside to the outside; the connecting plate 211 is arranged on the door plate 2 and is fixedly connected with the door plate 2 through the fixing nail 210 penetrating into the mounting hole 200, the fixing nail 210 comprises a nail body part 2100 located in the mounting hole 200 and a flange part 2101 located at one end of the nail body part 2100 and at the position outside the mounting hole 200, a second wedge-shaped block 2102 is arranged around the nail body part 2100, the second wedge-shaped block 2102 abuts against the first wedge-shaped part 201, and the wedge surface of the second wedge-shaped block 2102 cooperates with the wedge surface of the first wedge-shaped part 201, a slant groove 2103 parallel to the axial direction of the second wedge-shaped block 2102 is further provided at the position corresponding to the second wedge-shaped block 2102 on the outer surface of the nail body part 2100, the groove bottom surface of the slant groove 2103 has a decreasing trend along the direction close to the flange part 2101 and is in sliding connection with the guide wheel at the bottom of the second wedge-shaped block 2102, a convex ring part is further arranged at the end of the nail body part 2100 away from the flange part 2101, and the convex ring part is connected with the second wedge-shaped block 2102 through a tension spring 2104; the connecting piece comprises a first connecting hole 220 provided on the door plate 2, a second connecting hole 221 provided on the positioning block 311 and the adjusting block 312 and corresponding to the first connecting hole 220, movable pull blocks 222 respectively located in the first connecting hole 220 and the second connecting hole 221, and a connecting steel cable 223 having two ends respectively connected with the two movable pull blocks.

[0036] In combination with the above embodiments, it needs to be explained that, since the fastening connector 20 comprises a fastener and a connector, the fastening connector 20 can fasten the adjusting block 312 and the positioning block 311 to the door plate 2, and the connector can provide a certain gap between the adjusting block 312 and the door plate 2. Here, the fastening connector 20 between the adjusting block 312 and the door plate 2 is taken as an example for illustration. When the user fastens the adjusting block 312 to the door plate 2, first, the connecting plate 211 is placed on the door plate 2, and the fixing nail 210 is inserted through the door plate 2 and into the mounting hole 200. When the shank 2100 of the fixing nail 210 is inserted into the mounting hole 200, the wedge surface of the first wedge-shaped part 201 and the wedge surface of the second wedge-shaped part 2102 in the mounting hole 200 match each other. Therefore, when the fixing nail 210 is inserted into the mounting hole 200, the first wedge-shaped part 201 guides and presses the second wedge-shaped part 2102, so that the second wedge-shaped part 2102 slides downward along the inclined groove 2103 through the guide wheel at the bottom of the second wedge-shaped part 2102. At the same time, when the second wedge-shaped part 2102 slides downward, the second wedge-shaped part 2102 can pull the extension spring 2104 to be elongated, so that the second wedge-shaped part 2102 is disengaged from the first wedge-shaped part 201, and the fixing nail 210 can be inserted. After the fixing nail 210 is inserted, that is, when the second wedge-shaped part 2102 is disengaged from the first wedge-shaped part 201 and moves to the rear part of the first wedge-shaped part 201, the first wedge-shaped part 201 does not hinder the second wedge-shaped part 2102. Therefore, the spring after being elongated can pull the second wedge-shaped part 2102 to return to the initial position under the action of the elastic restoring force, so that the second wedge-shaped part 2102 is tightly engaged with the first wedge-shaped part 201, and the connecting plate 211 is locked with the door plate 2. Since the connecting plate 211 and the adjusting block 312 are connected by the connector, the fastening between the adjusting block 312 and the door plate 2 is further achieved. Furthermore, when the adjusting block 312 adjusts and corrects the bent and deformed door plate 2, the two movable pull blocks 222 can move in the first connecting hole 220 and the second connecting hole 221, respectively, until they reach the maximum stroke (as shown in Figure 3 , the first connecting hole 220 and the second connecting hole 221 have protrusions at the inner part near the opening end, which are used to block the movable pull block 222 from being pulled out), at this time, the adjusting block 312 still has a movement tendency with the continuous rotation of the threaded screw rod 3100, but at this time, the connecting steel cable 223 is in a taut state due to the blocking of the movable pull block 222, and the connecting steel cable 223 applies a pulling force to the door plate 2 to straighten and correct the deformed part of the door plate 2.

[0037] Based on the above embodiments, in order to further strengthen the connection between the fixing nail 210 and the mounting hole 200 and avoid the fixing nail 210 from falling off when adjusting and correcting the door plate 2, the auxiliary fixing part is further arranged on the protruding ring part, such asFigure 4 The auxiliary fixing member comprises an inflation cavity 2105, a piston push rod 2106, a groove, an expansion bag 2107 and a deformation plate 2108, the inflation cavity 2105 is arranged along the axial direction of the shank part 2100 and is arranged in the inner part of the convex ring part in a circumferential array, the piston push rod 2106 is arranged in the inflation cavity 2105 and one end thereof abuts against the second wedge block 2102, the groove is arranged on the outer surface of the convex ring part and corresponds to the inflation cavity 2105 one by one, the expansion bag 2107 is embedded in the groove and is communicated with the inflation cavity 2105 through a communication pipe, the deformation plate 2108 is arranged at the opening of the groove, is used for plugging the groove and the lower surface thereof is in contact with the expansion bag 2107, and a limiting groove in a concave arc shape is further arranged in the inner part of the small-diameter end and corresponds to the position of the auxiliary fixing member.

[0038] Based on the above embodiment, when the fixing nail 210 is penetrated into the sleeve and is installed, the second wedge block 2102 is pulled back to the original position by the tension spring 2104, because the second wedge block 2102 and one end of the piston push rod 2106 are always in abutting state, that is, the length of the piston push rod 2106 is greater than the original length of the tension spring 2104, therefore, in the process of the second wedge block 2102 returning to the original position, the second wedge block 2102 pushes the piston push rod 2106 to move in the inflation cavity 2105, so that the piston push rod 2106 pushes the gas in the inflation cavity 2105 to enter the expansion bag 2107 through the communication pipe, and then the expansion bag 2107 is expanded to extrude the deformation plate 2108, and then the deformation plate 2108 is arched by the expansion bag 2107, so as to be matched with the limiting groove, thereby further enhancing the connection strength between the fixing nail 210 and the installation hole 200, avoiding the falling of the fixing nail 210 under the large correction tension, that is, the inflation cavity 2105 and the piston push rod 2106 form a structure similar to a "pump" in the scheme, and the deformation plate 2108 is preferably made of a metal sheet with certain ductility.

[0039] Embodiment 2

[0040] For details, please refer to Figure 2As shown, the present embodiment is based on embodiment 1, and it should be noted that since the deformation of the door plate 2 itself is a continuous process, its deformation amount is very small in the early stage of deformation, so it is difficult for the technician to discover in time, and by the time the final discovery is made, the deformation amount of the door plate 2 is already very large. At this time, if the adjustment and correction are carried out, it often needs to consume greater correction effort to adjust, and at the same time, in the correction process, it is also easy to cause the door leaf to break and damage, so in order to ensure that the adjusting mechanism 3 can discover in time in the early stage of deformation of the door leaf, the present embodiment proposes another preferred embodiment, that is, the outer frame 30 includes two columns 300 and a connecting block 301; the two columns 300 are arranged along the length direction of the door leaf skeleton frame 1, and one end thereof is connected through the connecting block 301, and the other end is connected with the upper part of the door leaf skeleton frame 1, so as to form a rectangular frame structure, and the outer part of the two columns 300 and the inner side of the door plate 2 are both provided with the detection assembly 4. It should be noted that the present scheme is characterized by providing the detection assembly 4 for detecting the deformation amount of the door leaf, so as to ensure that the door leaf can be detected in time when it starts to warp and deform, so as to promote the adjusting mechanism 3 to start the adjustment and correction work in the early stage of deformation of the door leaf according to the detection result, so as to realize the timely adjustment and correction of the adjusting mechanism 3 to the warped and deformed door plate 2, so as to improve the use effect, and in order to ensure that the detection assembly 4 can accurately detect the deformation of the door plate 2 in time, the detection assembly 4 is preferably installed at the upper and lower ends of the two columns 300 in the present scheme, so as to facilitate the timely and accurate detection of the upper and lower deformation of the door plate 2.

[0041] As Figure 6 and Figure 7Further to the detection assembly 4, any detection assembly 4 comprises a sleeve 40 with one open end and the other closed end, and the closed end of the sleeve 40 penetrates into the column 300, the inside of the sleeve 40 is slidingly provided with a sliding block 41, the side of the sliding block 41 towards the open end of the sleeve 40 is connected with a push rod 42 extending to the outside of the sleeve 40, and the end of the push rod 42 away from the sliding block 41 is connected with the door plate 2 through a ball joint 43, and a laser ranging sensor 44 is also installed at the position of the closed end of the sleeve 40, a calibration plate 45 is also provided on the side of the sliding block 41 corresponding to the laser ranging sensor 44, and a displacement sensor 46 is also installed on the inner wall of the sleeve 40, and the displacement sensor 46 is used to monitor the displacement of the sliding block 41 and is electrically connected with the laser ranging sensor 44. It should be noted that based on the above design, when the door plate 2 is warped and deformed, the door plate 2 will drive the push rod 42 to move the sliding block 41 in the sleeve, and when the sliding block 41 slides, the displacement sensor 46 inside it generates a corresponding electrical signal after detecting the linear motion of the sliding block 41 and transmits it to the laser ranging sensor 44, to connect the current of the laser ranging sensor 44, so that it starts to work, and then measures the distance change between the calibration plate 45 and the laser ranging sensor 44, to identify the deformation direction of the door leaf. Specifically, when the laser ranging sensor 44 measures that the distance of the calibration plate 45 gradually increases, it means that the upper and lower parts of the door plate 2 have been warped and deformed, at this time it is necessary to rotate the adjusting screw clockwise to drive the adjusting block 312 to move towards the direction of gradually approaching the positioning block 311, and then tension the two to exert a downward tension on the warped position of the door plate 2 to correct and straighten it. Conversely, the adjusting rod can be rotated counterclockwise. Therefore, through the setting of the laser ranging sensor 44, the moving distance of the sliding block can also be measured in real time when the adjusting mechanism 3 adjusts and corrects the door leaf, to ensure the adjustment and correction accuracy and maximize the recovery of the door leaf to the product delivery state after adjustment and correction.

[0042] Based on the above embodiment, it is further necessary to supplement that in order to facilitate the rotation of the adjusting rod 310, the door leaf framework 1 of the present scheme is preferably also provided with a power device for rotating the adjusting rod 310, and the power device and the laser ranging sensor 44 are signal connected through the central control unit integrated in the door leaf framework 1. The power device can select a servo motor according to the actual situation, so that after the laser ranging sensor 44 measures the distance change between the calibration plate 45 and the laser ranging sensor 44 and identifies the deformation direction and deformation amount of the door plate 2, the corresponding power device can be started to drive the adjusting rod 310 to rotate, and then adjust and correct the deformed door leaf.

[0043] Of course, it is additionally needed to be supplemented here that the present scheme does not limit the rotation mode of the adjusting rod 310, and in the actual production and shaping, a power source provided by a power device can also be selected not to be used, and a tool (such as an internal hexagonal wrench) is used to rotate the adjusting rod 310, and if the tool is used, corresponding adjusting holes can be opened at the corresponding positions of the upper and lower ends of the door leaf skeleton frame 1, so as to facilitate the insertion of the tool, and at this time, the laser ranging sensor 44 can be electrically connected with a warning device (such as a prompt light or a prompt sound player) installed on the door plate 2, so as to timely remind the worker to rotate the adjusting rod 310 through the tool after the deformation of the door plate 2, so as to realize the correction and adjustment of the deformed door leaf structure.

[0044] The above detailed description further describes the purposes, technical solutions and beneficial effects of the present application, and it should be understood that the above is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
