Description

Technical Field

[0001] The present invention relates to the field of handles, and in particular to a hinge structure. Background Art

[0002] A hinge structure generally refers to two connecting parts connected by an axis or a pivot, allowing one of the parts to rotate around the axis or pivot. Existing cookware handles often use this structure to allow the handle to be rotatably connected to the side of the pot. Many cookware handles adopt a rotatable design to improve the convenience and flexibility of the cookware, making it easier to operate and carry.

[0003] However, due to the existence of the rotatable handle, the connection between the handle and the pot body often forms a certain angle. Unlike a fixed handle, a rotatable handle usually requires a rotating structure to be designed for rotatable connection with the pot body. During the use of the cookware, food residues, oil stains and other dirt will inevitably accumulate at the corner between the rotatable handle and the pot body, which brings inconvenience to cleaning. Specifically, in order to achieve the rotatable connection between the handle and the pot body, the end of the handle will be bent or connected to a special rotating shaft to form an L-shape, and a connecting seat will be provided on the side of the pot body, and a hole will be reserved on the connecting seat for installing the end of the handle. The end of the handle can be inserted into the hole and rotated to cooperate with it. However, the design of the handle will cause its corner to stick to the connecting seat. When a rag is needed for cleaning, the edge of the rag is difficult to completely fit the contour of the corner, resulting in the inability to clean every inch of the surface. Or, even if the rag can reach the corner, the dirt may have accumulated and solidified for a long time. Since the reserved handle width of an ordinary handle is usually 4-6 cm, it is often difficult for users to exert enough force to clean the dirt in such a small space. Therefore, although the rotating design of the pot handle brings convenience, it also causes the practical problem of inconvenience in cleaning, and its structure is in urgent need of improvement. Summary of the Invention

[0004] The present invention aims to provide a hinge structure to solve the problem that the corner of the rotatable handle will abut against the connection seat on the pot body for mounting the handle. When a rag is needed for cleaning, the edge of the rag cannot completely conform to the contour of the corner, resulting in the inability to clean every inch of the surface. The specific technical solution is as follows:

[0005] A hinge structure comprises a fixed part and a curved handle, wherein the opposite ends of the fixed part are respectively provided with a rotating part and a limiting part, an elastic telescopic rod is provided inside the fixed part, one end of the elastic telescopic rod extends to the interior of the rotating part, and the other end of the elastic telescopic rod is connected to the limiting part, the first end of the handle is detachably plugged into the rotating part, and the handle configured to extend into the rotating part drives the elastic telescopic rod to displace laterally, the second end of the handle is sleeved on the limiting part, and the second end of the handle is rotatably connected to a locking part, and an unlocking part for cooperating with the locking part is provided on the limiting part, and is configured such that when the handle is rotated until the locking part is flush with the unlocking part, the laterally displaced elastic telescopic rod drives the limiting part and thereby causes the unlocking part to unlock the locking part.

[0006] As one of the improvements of the above technical solution, the rotating member is rotatably connected to the fixed portion, and the rotating member is provided with a groove for accommodating the first end of the handle.

[0007] As one of the improvements of the above technical solution, the elastic telescopic rod includes a telescopic rod body and a reset spring, the fixing portion is provided with a channel for installing the telescopic rod body, the channel is connected to the groove, and the reset spring is sleeved on the telescopic rod body.

[0008] As one of the improvements of the above technical solution, one end of the telescopic rod body is provided with a U-shaped limiting end, the U-shaped limiting end extends into the rotating part, the first end face of the handle is vertically connected to the limiting plate, the first end of the handle is arranged in the U-shaped limiting end, and the U-shaped limiting end limits the limiting plate.

[0009] As one of the improvements of the above technical solution, a trigger end is provided at one end of the telescopic rod body, the U-shaped limit end is below the trigger end, an inclined surface is provided at the corner of the end face of the trigger end, and an extrusion end is connected to the side of the first end of the handle, and the extrusion end is used to cooperate with the trigger end to push the elastic telescopic rod to move laterally.

[0010] As one of the improvements of the above technical solution, a mounting groove is provided on the bottom surface of the groove, a spring is provided in the mounting groove, the top end of the spring is exposed from the notch of the mounting groove, and the top end of the spring is connected to a top plate, which is abutted against the limit plate.

[0011] As one of the improvements of the above technical solution, the second end of the handle is forked to form two connecting ends, the locking member is an annular rotating member, one end of the annular rotating member is rotatably connected to the connecting end, and the other end of the annular rotating member is provided with a threaded structure on the inner side, and a connecting member is provided on the second end of the handle, and the connecting member is Y-shaped, and the two ends of the connecting member are respectively threadedly connected to the connecting members on the two connecting ends.

[0012] As one of the improvements of the above technical solution, a tooth groove is provided on the outer side of the annular rotating member, and the unlocking portion includes a rack, which is laterally connected to the side surface of the limiting portion.

[0013] As one of the improvements of the above technical solution, the telescopic rod body is rotatably connected to the end surface of the limiting portion.

[0014] The beneficial effects of the present invention are as follows: by applying a downward force to the handle, the first end of the handle pushes the elastic telescopic rod and thereby drives the limiting part to move. When the limiting part moves, the unlocking part simultaneously drives the locking element, thereby enabling the handle to be separated from the fixing part with a simple one-handed operation. By separating the handle from the fixing part, the handle and the fixing part can be cleaned in all directions.

[0015] In order for the handle to be unlocked from the fixed part, two conditions must be met. One is to drive the handle to rotate relative to the fixed part so that the locking part on the handle and the unlocking part of the limit part are at the same height. The second is to apply sufficient downward force to the handle or the first end of the handle on the basis of the above. The above design is adopted to prevent the handle from being separated from the fixed part due to accidental touch during daily use, thereby preventing accidents.

Of course, it is not necessary to achieve all of the advantages described above at the same time to implement any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] Since the corner of the existing rotatable handle 2 is close to the connection base for mounting the handle 2 on the pot body, when a rag is needed for cleaning, the edge of the rag is difficult to completely fit the contour of the corner, resulting in the problem of not being able to clean every inch of the surface. Figure 1-7The present invention provides an embodiment to solve the above-mentioned problem. The embodiment is mainly applied to a handle 2 of a stove or a pot. Of course, it is not limited to the above two and can also be applied to other devices that need to use a similar handle 2. Specifically, it includes a fixed part 1 and a curved handle 2. The opposite ends of the fixed part 1 are respectively provided with a rotating part 3 and a limiting part 4, wherein the rotating part 3 is rotatably connected to one end of the fixed part 1, and the limiting part 4 is abutted against the other end of the fixed part 1. An elastic telescopic rod 7 is provided inside the fixed part 1, one end of the elastic telescopic rod 7 extends to the inside of the rotating part 3, and the other end of the elastic telescopic rod 7 is connected to the limiting part 4. The first end 21 of the handle 2 The handle 2 is detachably plugged into the rotating member 3 and configured to extend into the rotating member 3 to drive the elastic telescopic rod 7 to move laterally. The second end 22 of the handle 2 is sleeved on the limiting portion 4. The second end 22 of the handle 2 is rotatably connected to the locking member 5. In this embodiment, the locking member 5 functions to lock the second end 22 of the handle 2. When the locking member 5 is unlocked, the second end 22 of the handle 2 can be directly detached from the limiting portion 4. The limiting portion 4 is provided with an unlocking portion 6 for cooperating with the locking member 5. When the handle 2 is rotated until the locking member 5 is flush with the unlocking portion 6, the laterally displaced elastic telescopic rod 7 drives the limiting portion 4 and then causes the unlocking portion 6 to unlock the locking member 5.

[0029] By default or without external force, the handle 2 will naturally hang down due to gravity. At this time, the handle 2 will be below the fixing part 1. When the handle 2 needs to be separated from the fixing part 1, the handle 2 needs to be rotated. In this embodiment, the handle 2 needs to be held and rotated 180 degrees relative to the fixing part 1. At this time, the handle 2 will be rotated from just below the fixing part 1 to just above the fixing part 1, and the locking part 5 on the handle 2 and the unlocking part 6 of the limiting part 4 will be at the same height. By giving the handle 2 or The first end 21 of the handle 2 applies a downward force, so that the first end 21 of the handle 2 pushes the elastic telescopic rod 7 and then drives the limiting part 4 to move. When the limiting part 4 moves, it will drive the unlocking part 6 to unlock the locking member 5. It should be noted that if the locking member 5 on the handle 2 and the unlocking part 6 of the limiting part 4 are at different heights, the unlocking part 6 will be restricted in its displacement by the handle 2 because there is no locking member 5 to cooperate with it. As a result, the first end 21 of the handle 2 cannot press down to push the elastic telescopic rod 7, and thus cannot be unlocked.

[0030] Based on the above description, it can be known that in this embodiment, two conditions must be met in order to unlock the handle 2 from the fixed part 1. One is to drive the handle 2 to rotate relative to the fixed part 1 so that the locking member 5 on the handle 2 and the unlocking portion 6 of the limiting portion 4 are at the same height. The second is to apply sufficient downward force to the handle 2 or the first end 21 of the handle 2 on the basis of the above. The above design is adopted to prevent the handle 2 from being separated from the fixed part 1 due to accidental touch during daily use, thereby preventing accidents.

[0031] Regarding the first end 21 of the handle 2 pushing the elastic telescopic rod 7, please refer to Figure 2 Specifically, the rotating member 3 is provided with a groove for accommodating the first end 21 of the handle 2, and the elastic telescopic rod 7 includes a telescopic rod body 71 and a return spring 72. The fixing portion 1 is provided with a channel for installing the telescopic rod body 71, the channel is communicated with the groove, and the return spring 72 is sleeved on the telescopic rod body 71. Specifically, the fixing portion 1 is provided with an accommodating space communicated with the channel on the side of the channel for accommodating the return spring 72. In this embodiment, a limit block protruding outward is connected to the side of the telescopic rod body 71, and the limit block is placed in the above-mentioned accommodating space. The two ends of the return spring 72 sleeved on the telescopic rod body 71 are respectively connected to the limit block and the inner wall of the accommodating space. In this way, the return spring 72 can act on the telescopic rod body 71, so that the telescopic rod body 71 can be elastically extended and retracted;

[0032] The U-shaped limiting end 8 is used to limit the position of the limiting plate 211.

[0033] In order to facilitate the first end 21 of the handle 2 to drive the telescopic rod body 71, a trigger end is provided at one end of the telescopic rod body 71, and the U-shaped limit end 8 is below the trigger end, or the trigger end and the U-shaped limit end 8 are arranged in parallel and are commonly connected to the same end of the telescopic rod body 71, and an inclined surface 711 is provided at the corner of the end face of the trigger end. Correspondingly, the first end 21 of the handle 2 is connected to the side of the extrusion end 212. Taking the handle 2 being directly above the fixed part 1 as an example, the extrusion end 212 is directly above the trigger end. When a downward force is applied to the handle 2 or the first end 21 of the handle 2, the first end 21 of the handle 2 will drive the limit plate 211 and the extrusion end 212 to move downward. After a certain period of time, the extrusion end 212 will contact the trigger When the first end 21 of the handle 2 or the first end 21 of the handle 2 is in contact with the first end 21 (the inclined surface 711 of the trigger end), if a downward force is continued to be applied to the handle 2 or the first end 21 of the handle 2, the squeezing end 212 will push the trigger end backward, that is, the trigger end will drive the entire telescopic rod body 71 to retreat. The provision of the inclined surface 711 on the trigger end also facilitates the squeezing end 212 to push the trigger end more easily, thereby achieving the lateral displacement of the telescopic rod body 71. The telescopic rod body 71 will also drive the limiting portion 4 during the displacement. Since the locking member 5 on the handle 2 and the unlocking portion 6 of the limiting portion 4 are at the same height at this time, the locking member 5 can be unlocked with the cooperation of the unlocking portion 6, so that the user can unlock both ends of the handle 2 at the predetermined position by applying force to the handle 2 with one hand.

[0034] Applying a force to the first end 21 of the handle 2 will cause the first end 21 of the handle 2 to continue to penetrate into the groove of the rotating part 3 and cannot be restored. To this end, the present invention also provides some embodiments to solve the above technical problems. Specifically, the bottom surface of the groove is provided with a mounting groove, and a spring 9 is provided in the mounting groove. The top end of the spring 9 is exposed from the notch of the mounting groove, and the top end of the spring 9 is connected to a top plate 10, and the top plate 10 is abutted against the limit plate 211. In this embodiment, the function of the spring 9 is not only to help the first end 21 of the handle 2 to reset. By default, supported by the spring 9, the top plate 10 or the limit plate 211 will be lifted to a predetermined position by the spring 9. Secondly, the setting of the spring 9 is also an auxiliary condition for triggering the above-mentioned unlocking condition one. It can be understood that if you want to apply downward pressure to the first end 21 of the handle 2, you need to compress the spring 9 at the same time to ensure that the first end 21 of the handle 2 needs to apply sufficient force to press down the handle 2 during daily use.

[0035] The details of the cooperation between the locking member 5 and the unlocking portion 6 are as follows:

[0036] See also Figure 6The second end 22 of the handle 2 is divided into two connecting ends 221, and the locking member 5 is an annular rotating member 222. One end of the annular rotating member 222 is rotatably connected to the connecting end 221, and the inner side of the other end of the annular rotating member 222 is provided with a threaded structure. It can be understood that the annular rotating member 222 is similar to a nut, and one end of the annular rotating member 222 is rotatably connected to the connecting end 221, and the other end of the annular rotating member 222 has a threaded structure and is arranged outward. A connecting member 223 is provided on the second end 22 of the handle 2. The connecting member 223 is Y-shaped, and the two ends of the connecting member 223 are respectively threadedly connected to the connecting members 223 on the two connecting ends 221. Specifically, since the second end 22 of the handle 2 is divided and detachably connected to the Y-shaped connecting member 223, the second end 22 of the handle 2 will cooperate with the connecting member 223 to enclose a hole that can accommodate the limiting portion 4. By default, the limiting portion 4 Placed in the hole, the outer side of the annular rotating member 222 is provided with a tooth groove, and the unlocking part 6 includes a rack, which is laterally connected to the side of the limiting part 4. In this way, the above-mentioned setting of the locking member 5 on the handle 2 and the unlocking part 6 of the limiting part 4 at the same height is to set the rack and the annular rotating member 222 at the same height. When the limiting part 4 is laterally displaced, the limiting part 4 will drive the rack to gradually approach the annular rotating member 222. Finally, the annular rotating member 222 will rotate under the push of the rack or the annular rotating member 222 will rotate relative to the connecting member 223 under the push of the rack. Since the connecting member 223 is connected to the annular rotating member 222 by a thread, rotating the annular rotating member 222 can unlock the connecting member 223, separate the annular rotating member 222 from the connecting member 223, and then achieve unlocking. At this time, the handle 2 can be separated from the limiting part 4.
