Description

Technical Field

[0001] The invention relates to the technical field of auxiliary devices for adjusting door panels, and in particular to an anti-warping straightener and a straightening profile thereof. Background Art

[0002] Cabinet doors or door panels of houses are prone to bending and deformation after long-term use. It is necessary to open a strip groove on the door panel and fix a straightener in the groove to prevent the door panel from deformation. At present, the straightener mainly includes a straightening profile and a push-pull rod assembly arranged in the straightening profile. When in use, it is necessary to use an external tool to extend into the straightening profile to cooperate with the push-pull rod assembly and rotate the push-pull rod assembly to make the straightening profile bend and deform to a certain extent to adjust the curvature of the door and achieve the effect of straightening the door. The straightening profile in the prior art has unreasonable design, which causes the straightener to "warp" during use, that is, the end of the straightener warps or even detaches from the door panel, which not only affects the straightening effect, but also the straightener protruding from the surface of the door panel is prone to safety hazards. Summary of the invention

[0003] The present invention aims to provide an anti-warping straightener and a straightening profile thereof, which can at least solve one of the above-mentioned technical problems.

[0004] The technical solution of the present invention is achieved in this way:

[0005] Straightening profile, comprising:

[0006] The main body has a cylindrical first through hole extending through the main body along the length direction;

[0007] An arc portion, which is arranged above the main body, and the width of the arc portion in the transverse direction is greater than that of the main body, so that two ends of the arc portion form a left tenon portion and a right tenon portion protruding from the main body;

[0008] The arc surface portion includes a first arc surface located at the top of the arc surface portion, and a curvature of the first arc surface is smaller than a curvature of the first through hole.

[0009] After the straightened profile of the present invention is installed in the strip groove in the door panel, the left tenon part and the right tenon part are engaged with the strip groove, which plays the role of clamping the straightened profile and increasing the force-bearing area. The arc surface part is arranged above the main body part, so that the left tenon part and the right tenon part are close to the top of the first through hole, forming an arch bridge structure, avoiding the position where the wall thickness is thin in the middle of the main body part, so that the straightened profile of the present invention is not easy to deform in the radial direction when subjected to the extrusion force of the door panel, so that the connection stability of the straightened profile and the door panel is high, and it is not easy to lift up from the door panel, and has the effect of preventing the head from lifting up.

[0010] Since the straightened profile bends back and forth in the longitudinal direction during use, by setting a first curved surface with a smaller curvature, the area in the longitudinal direction is increased while ensuring that the first curved surface is subjected to uniform force, and the direction of the force acting on the first curved surface after the straightened profile is installed in the door panel is changed, so that more force components parallel to the longitudinal direction act on the door panel, thereby saving the external force required for straightening the door panel and improving the straightening effect.

[0011] Furthermore, the arc surface portion further includes a first plane and a second plane perpendicular to the longitudinal direction, the first plane forming the bottom surface of the left tenon portion, and the second plane forming the bottom surface of the right tenon portion.

[0012] Further, the outer surface of the main body has a third plane and a fourth plane parallel to the longitudinal direction;

[0013] The third plane is connected to the lower part of the left tenon portion, and the fourth plane is connected to the lower part of the right tenon portion.

[0014] Furthermore, the outer surface of the main body also has a first curved surface and a second curved surface;

[0015] The first plane, the third plane, and the first curved surface are smoothly transitioned and sequentially connected to the left end of the first arc surface;

[0016] The second plane, the fourth plane, and the second curved surface are smoothly transitioned and sequentially connected to the right end of the first arc surface.

[0017] Furthermore, the straightened profile also includes a rectangular support portion connected below the main body portion, and a rectangular plate portion connected below the support portion.

[0018] Furthermore, the distance between the top of the arc surface and the plate body is H; the distance between the bottom of the arc surface and the plate body is h;

[0019] 3 / 4H<h<4 / 5H.

[0020] Furthermore, a left tenon groove and a right tenon groove are symmetrically arranged on both sides of the main body, and the left tenon groove and the right tenon groove are arranged close to the bottom of the main body.

[0021] Furthermore, the first arc surface is composed of a plurality of first sub-arc surfaces arranged at intervals, and a groove extending along the length direction of the straightened profile is provided between two adjacent first sub-arc surfaces.

[0022] The present invention further provides an anti-warping straightener, which comprises the straightening profile mentioned above, and a push-pull rod assembly passing through a first through hole of the straightening profile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] Combine the following Figures 1 to 4 The technical solution provided by the present invention is described in more detail.

[0030] like Figure 1 The straightened profile 1 of the present invention comprises:

[0031] The main body 11 has a cylindrical first through hole 111 extending through the main body 11 along the length direction.

[0032] The arc portion 12 is arranged above the main body, and the width of the arc portion in the transverse direction is greater than that of the main body, so that two ends of the arc portion form a left tenon portion 121 and a right tenon portion 122 protruding from the main body;

[0033] The arc surface portion includes a first arc surface 123 located at the top of the arc surface portion, and a curvature of the first arc surface 123 is smaller than a curvature of the first through hole 111 .

[0034] in, Figure 1 The X direction represents the horizontal direction, and the Y direction represents the vertical direction.

[0035] like Figure 2 As shown, after the straightened profile 1 of the present invention is installed in the strip groove 21 preset in the door panel 2, the left tenon portion 121 and the right tenon portion 122 are engaged with the strip groove, which plays the role of clamping the straightened profile and increasing the force-bearing area. The arc surface portion 12 is arranged above the main body, so that the left tenon portion 121 and the right tenon portion 122 are close to the top of the first through hole 111, forming an arch bridge structure, avoiding the thinner wall thickness of the middle part of the main body 11, so that the straightened profile of the present invention is not easy to deform in the radial direction when subjected to the extrusion force of the door panel, so that the connection stability of the straightened profile and the door panel is high, and it is not easy to lift from the door panel.

[0036] Since the straightened profile 1 bends forward and backward along the longitudinal direction during use, by setting a first curved surface 123 with a smaller curvature, the area in the longitudinal direction is increased while ensuring that the first curved surface is subjected to uniform force, and the direction of the force acting on the first curved surface 123 after the straightened profile 1 is installed in the door panel 2 is changed, so that more force components parallel to the longitudinal direction act on the door panel, thereby saving the external force required for straightening the door panel and improving the straightening effect.

[0037] The arc surface portion 12 further includes a first plane 124 and a second plane 125 perpendicular to the longitudinal direction, wherein the first plane 124 forms the bottom surface of the left tenon portion 121, and the second plane 125 forms the bottom surface of the right tenon portion 122. The first plane 124 and the second plane 125 perpendicular to the longitudinal direction are provided so that the pressure applied to the door panel 2 when the straightening profile 1 is bent and deformed is exactly parallel to the longitudinal direction, which can save the external force required for straightening the door panel and improve the straightening effect.

[0038] Since the cross section of the first through hole 111 is circular, the width in the middle is the largest, and the portion of the straightened profile 1 corresponding to the middle position of the first through hole 111 is relatively thin, the compression of the door panel 2 on this portion may cause the straightened profile 1 to deform in the radial direction, affecting the use of the straightened profile. Therefore, the outer surface of the main body 11 has a third plane 112 and a fourth plane 113 parallel to the longitudinal direction; the third plane 112 is connected to the bottom of the left tenon 121, and the fourth plane 113 is connected to the bottom of the right tenon 122. Thus, the third plane 112 and the fourth plane 113 are directly opposite to the middle of the first through hole 111. Since the third plane 112 and the fourth plane 113 are both planes perpendicular to the transverse direction, less force acts on the third plane 112 and the fourth plane 113 when the straightened profile 1 is bent forward and backward along the longitudinal direction during use, which can avoid the door panel 2 from squeezing the middle position of the first through hole 111.

[0039] To avoid stress concentration, the lower outer surface of the main body is gradually narrowed inwardly by a curved surface. Specifically, the outer surface of the main body 11 also has a first curved surface 114 and a second curved surface 115; the first plane 124, the third plane 112, and the first curved surface 114 are smoothly transitioned and sequentially connected to the left end of the first curved surface 123; the second plane 125, the fourth plane 113, and the second curved surface 115 are smoothly transitioned and sequentially connected to the right end of the first curved surface 123.

[0040] The straightened profile 1 also includes a rectangular support portion 13 connected to the bottom of the main body 11, and a plate body portion 14 connected to the bottom of the support portion 13. When the straightened profile 1 is used, a strip groove 21 having the same cross-sectional shape as the straightened profile needs to be opened on the door panel 2, and the straightened profile 1 is embedded in the door panel 2 from top to bottom. One side of the plate body portion 14 away from the main body 11 is exposed to the door panel 2, which has a decorative effect.

[0041] When the straightened profile 1 is embedded in the door panel 2, the portion of the door panel 2 between the curved surface portion 12 and the plate body portion 14 is squeezed by the left tenon portion 121, the right tenon portion 122, and the plate body portion 14. If the thickness of the door panel portion is too thin, it is easy to deform under the squeezing action of the left tenon portion 121, the right tenon portion 122, and the plate body portion 14, thereby causing the straightened profile 1 to loosen in the door panel 2. The present invention increases the thickness of the door panel portion embedded between the curved surface portion 12 and the plate body portion 14 by moving the left tenon portion 121 and the right tenon portion 122 for engagement upward, so that the door panel 2 is not easily deformed locally, and the straightened profile 1 is prevented from loosening in the door panel 2.

[0042] Among them, the distance between the top of the arc surface part 12 and the plate body part 14 is H; the distance between the bottom of the arc surface part 12 and the plate body part 14 is h; experimental data show that when 3 / 4H<h<4 / 5H, the length of the straightened profile 1 in the longitudinal direction can be moderate, and at the same time, the straightened profile 1 and the door panel 2 are closely matched, and the door panel part embedded between the arc surface part 12 and the plate body part 14 is not easily squeezed and deformed.

[0043] It should be noted that the length of h is also related to the curvature of the first arc surface 123 and the width of the arc surface portion 12 , and a suitable length can be adopted according to actual usage.

[0044] In order to further increase the contact area between the straightened profile 1 and the door panel 2 and enhance the tightness of the fit between the straightened profile 1 and the door panel 2, a left tenon groove 116 and a right tenon groove 117 are symmetrically arranged on both sides of the main body, and the left tenon groove 116 and the right tenon groove 117 are arranged close to the bottom of the main body 11.

[0045] The present invention further provides an anti-warping straightener, which comprises the straightening profile mentioned above, and a push-pull rod assembly passing through a first through hole of the straightening profile.

[0046] Specifically, Figure 3 As shown, the push-pull rod assembly includes a rod body 3 and an internal and external thread nut 4, one end of the rod body 3 is fixedly connected to the straightened profile 1, and the other end thereof is matched with the internal thread of the internal and external thread nut 4. The external thread of the internal and external thread nut 4 is matched with the internal thread on the straightened profile 1. Since the thread matching directions of the internal and external thread nut 4, the rod body 3 and the straightened profile 1 are different, when the internal and external thread nut 4 is rotated, the rod body 3 and the straightened profile 1 have a tendency to move in opposite directions, but since the connecting portion of the rod body 3 is fixedly connected to the straightened profile 1, the straightened profile 1 will bend and deform, and the deformation of the straightened profile 1 can cause the door panel connected thereto to deform accordingly, thereby achieving the effect of correcting the bent door panel.

[0047] Preferably, the straightened profile 1 is an aluminum profile.

[0048] Example 2

[0049] The technical solution of this embodiment is basically the same as the technical solution of Embodiment 1, the main difference being that the first arc surface 123 is composed of a plurality of first sub-arc surfaces 1231 arranged at intervals, and a groove 1232 extending along the length direction of the straightened profile is provided between two adjacent first sub-arc surfaces 1231.

[0050] The groove 1232 is provided to further increase the contact area between the straightened profile 1 and the door panel 2, and improve the connection stability between the straightened profile 1 and the door panel 2 through multiple bites.
