On the plate, the movable plate has a tendency to move forward under the elastic force of the tension spring, thereby making the interlayer wider; the rear part of the operating handle is movably connected to a toggle member, the front part of the toggle member is movably connected to the rear part of the operating handle, the middle part of the toggle member is rotatably connected to the handle body via a toggle shaft, and the rear part of the toggle member is movably connected to the rear part of the movable plate; after holding the handle body and pinching the operating handle, the operating handle rotates around the handle shaft at its front, so that the rear part of the operating handle drives the toggle member to rotate around its toggle shaft. After the toggle member rotates, its rear part toggles the movable plate backward, thereby making the interlayer narrower, at which time the pot can be clamped in the interlayer. In the prior arts such as CN215227015U, CN215227014U, and CN216256811U, in order to keep the interlayer narrow, the operating handle needs to be locked, and when the handle needs to be removed, it needs to be unlocked.

[0003] The above-mentioned prior art detachable pot handles are based on the structural design of the unlocking mechanism. However, the unlocking operation requires a considerable force, and the ease of operation needs to be improved. Therefore, CN 118436267 A provides a detachable pot handle, which has the following structure: the handle includes a handle body, a movable plate disposed within the handle body that can move forward and backward along the handle body, the front end of the movable plate passing through the handle body, and a clip disposed at the front end of the movable plate, forming a sandwich between the clip and the front end of the handle body;

[0004] An operating handle is provided on the lower side of the handle body, and a handle shaft is fixedly provided at the front of the handle body. The front part of the operating handle is rotatably connected to the handle body through the handle shaft. A tension spring is provided between the handle shaft and the movable plate. The front end of the tension spring is hooked on the handle shaft, and the rear end of the tension spring is hooked on the movable plate. Under the elastic force of the tension spring, the movable plate has a tendency to move forward, thereby making the interlayer wider.

[0005] The rear part of the operating handle is movably connected to a toggle member, the front part of the toggle member is movably connected to the rear part of the operating handle, the middle part of the toggle member is rotatably connected to the handle body through a toggle shaft, and the rear part of the toggle member is movably connected to the rear part of the movable plate;

[0006] The handle body is gripped by hand, and after the operating handle is pinched, the operating handle rotates around the handle rotation axis at the front thereof, so that the rear portion of the operating handle drives the toggle member to rotate around the toggle rotation axis. After the toggle member rotates, the rear portion of the toggle member toggles the movable plate to move backward, thereby making the interlayer narrower;

[0007] The invention also includes a locking mechanism and an unlocking mechanism. When the interlayer is narrow, the locking mechanism locks the operating handle, thereby locking the toggle member connected to the operating handle to keep the interlayer narrow. When the unlocking mechanism is operated to unlock the locking mechanism, the movable plate automatically moves forward under the elastic force of the tension spring, thereby widening the interlayer.

[0008] The locking mechanism includes: a locking tooth block is fixed to the rear of the operating handle, and a locking tooth row is provided on the rear end surface of the locking tooth block;

[0009] The handle body is also rotatably connected to a positioning tooth block via a positioning shaft. The positioning shaft is provided through the lower part of the positioning tooth block. The positioning tooth block is located behind the locking tooth block. A positioning spring is provided at the rear of the positioning tooth block to support the positioning tooth block so that it has a tendency to rotate forward. A positioning tooth row is provided on the front end surface of the positioning tooth block.

[0010] When the operating handle is pinched and rotated, the locking tooth block moves until the locking teeth engage with the positioning teeth, thereby locking the operating handle;

[0011] The unlocking mechanism includes: an unlocking lever capable of moving forward and backward within the handle body; a first return spring disposed between the unlocking lever and the handle body; under the action of the first return spring, the unlocking lever tends to move forward, with the tail of the unlocking lever aligned with the upper portion of the positioning tooth block; an unlocking drive mechanism capable of driving the unlocking lever backward, thereby pushing the positioning tooth block backward through the unlocking lever, disengaging the locking teeth from the positioning teeth and achieving unlocking. The unlocking drive mechanism is an unlocking button disposed on the side of the handle body; pressing the unlocking button inward pushes the unlocking lever backward.

[0012] Although the above-mentioned detachable pot handle has made a major innovation in structure, there is still a possibility of misoperation of the unlocking button due to the lack of a safety device. Utility Model Content

After the toggle member rotates, the rear portion thereof toggles the movable plate to move backward, thereby making the interlayer narrower.

[0018] The invention also includes a locking mechanism and an unlocking mechanism. When the interlayer is narrow, the locking mechanism locks the operating handle, thereby locking the toggle member connected to the operating handle to keep the interlayer in a narrow state. When the unlocking mechanism is operated to unlock the locking mechanism, the movable plate automatically moves forward under the elastic force of the tension spring, thereby widening the interlayer.

[0019] The locking mechanism includes: a locking tooth block is fixed to the rear of the operating handle, and a locking tooth row is provided on the rear end surface of the locking tooth block;

[0020] The handle body is also rotatably connected to a positioning tooth block via a positioning shaft. The positioning shaft is provided through the lower part of the positioning tooth block. The positioning tooth block is located behind the locking tooth block. A positioning spring is provided at the rear of the positioning tooth block to support the positioning tooth block so that it has a tendency to rotate forward.

[0026] The handle is also provided with a safety mechanism, which includes:

[0027] A safety button is provided on the handle body and can be raised and lowered. The safety button extends from the upper surface of the handle body. A second return spring is provided between the safety button and the handle body. Under the action of the second return spring, the safety button is in a high locked position. The safety button can prevent the unlocking slide button from moving backward; after the safety button is pressed downward, the safety button no longer blocks the unlocking slide button.

[0028] Furthermore, the safety button is located in front of the unlocking slide button, and the unlocking slide button has a positioning arm extending forward, and the positioning arm cooperates with the safety button.

[0029] Furthermore, a limiting groove is provided on the bottom surface of the positioning arm, and a limiting block corresponding to the limiting groove is provided on the safety button;

[0030] When the safety button is in the high locked position under the action of the second return spring, the limit block is located in the limit groove, thereby preventing the unlocking slide button from moving backward; when the safety button is pressed downward, the limit block disengages from the limit groove.

[0031] Furthermore, the positioning block is further provided with a lock tongue capable of moving forward and backward, the lock tongue having a stop extending forward, and the safety button having a locking boss extending backward;

[0032] A third return spring is provided between the lock tongue and the positioning block. Under the action of the third return spring, the lock tongue extends forward from the positioning block and abuts against the safety button. When the safety button is pressed downward, the safety button pushes the lock tongue backward until the locking protrusion of the safety button is located below the stopper of the lock tongue. At this time, the stopper blocks the locking protrusion, so that the safety button remains in the low released position so that the safety button no longer blocks the unlocking slide button.

[0033] The unlocking slide button is provided with a downwardly protruding protrusion, and the lock tongue has a push groove, in which the protrusion is located. When the unlocking slide button is moved backward to unlock, the protrusion moves to the end of the push groove until it pushes the lock tongue, thereby driving the lock tongue to move backward, so that the stop of the lock tongue no longer blocks the locking shoulder, so that the safety button rises up under the action of the second return spring and presses against the positioning arm;

[0034] After the unlocking slide button is reset under the action of the first reset spring, the limiting block enters the limiting groove again.

[0035] Furthermore, the front end face of the lock tongue has a first inclined surface tilted backward, and the safety button has a second inclined surface adapted to the first inclined surface. Under the action of the third return spring, the lock tongue extends forward from the positioning block and the first inclined surface is against the second inclined surface of the safety button.

[0065] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0066] Reference Figure 1-Figure 22 A detachable pot handle includes a handle body 1, within which is disposed a movable plate 2 that can move forward and backward along the handle body 1. The front end of the movable plate 2 passes through the handle body 1. A clip is disposed at the front end of the movable plate 2, forming a sandwich layer between the clip and the front end of the handle body 1. To protect the pot and increase friction, a flexible layer 3, such as a silicone layer or rubber layer, is typically wrapped around the clip.

[0067] An operating handle 4 is provided on the lower side of the handle body 1, and a handle shaft 5 is fixedly provided at the front part of the handle body 1. The front part of the operating handle 4 is rotatably connected to the handle body 1 via the handle shaft 5. A tension spring 6 is provided between the handle shaft 5 and the movable plate 2. The front end of the tension spring 6 is hooked on the handle shaft 5, and the rear end of the tension spring 6 is hooked on the movable plate 2. Under the elastic force of the tension spring 6, the movable plate 2 tends to move forward, thereby making the interlayer wider. At this time, the detachable pot handle of the present invention can be removed from the pot.

[0068] The rear part of the operating handle 4 is movably connected to a toggle member 7, and the front part of the toggle member 7 is movably connected to the rear part of the operating handle 4. In one embodiment, a through hole is provided at the front part of the toggle member 7, and a linkage shaft 9 is provided at the rear part of the operating handle 4. The linkage shaft 9 penetrates into the through hole and has a movable space, thereby achieving the purpose of the movable connection between the two.

[0069] The middle portion of the toggle member 7 is rotatably connected to the handle body 1 via a toggle shaft 10, and the rear portion of the toggle member 7 is movably connected to the rear portion of the movable plate 2. In one embodiment, a shift fork 11 is provided at the rear portion of the toggle member 7, and a shift hole is provided at the rear portion of the movable plate 2. The shift fork 11 extends into the shift hole, so that when the toggle member 7 is rotated, the movable plate 2 can be moved via the shift fork 11.

[0070] After holding the handle body 1 and pinching the operating handle 4, the operating handle 4 rotates around the handle shaft 5 at the front, so that the rear part of the operating handle 4 drives the toggle member 7 to rotate around its toggle shaft 10. After the toggle member 7 rotates, the fork 11 at the rear thereof toggles the movable plate 2 to move backward, thereby making the interlayer narrower. At this time, the pot can be clamped in the interlayer of the detachable pot handle of the present invention.

[0071] It also includes a locking mechanism and an unlocking mechanism. When the interlayer is narrow, the locking mechanism locks the operating handle 4, thereby locking the toggle member 11 connected to the operating handle 4 to keep the interlayer narrow; operating the unlocking mechanism to unlock the locking mechanism, the movable plate 2 automatically moves forward under the elastic force of the tension spring 6 to make the interlayer wider.

[0072] The locking mechanism comprises:

[0073] A locking tooth block 12 is also fixed to the rear of the operating handle 4. In one embodiment, the linkage shaft 9 at the rear of the operating handle passes through the locking tooth block 12 and the two are fixed by interference fit or the like. The rear end face of the locking tooth block 12 is provided with a locking tooth row 13; the handle body 1 is also rotatably connected to a positioning tooth block 15 through a positioning shaft 14. The positioning shaft 14 is provided at the lower part of the positioning tooth block 15. The positioning tooth block 15 is located behind the locking tooth block 12, and a positioning spring 16 is provided at the rear of the positioning tooth block 15 to support the positioning tooth block 15 so that it has a tendency to rotate forward. A positioning tooth row 17 is provided on the front end face of the positioning tooth block 15.

[0074] In one embodiment, a mounting block is provided at the tail end of the handle body 1, the rear end of the positioning spring 16 is pressed against the mounting block, and the front end of the positioning spring 16 is pressed against the positioning tooth block 15. The toggle shaft 10 is fixedly provided on the mounting block, and the positioning shaft 14 is provided on the mounting block. The toggle shaft 10 and the positioning shaft 14 are the same shaft. The specific fixing and installation method of the mounting block can be: the mounting block is fixed to the handle body 1 by a fixed shaft 19 provided therein; a limiting hole 20 is provided on the toggle member 4 and the positioning tooth block 15, and the fixed shaft 19 passes through the limiting hole 20. The fixed shaft 19 can also serve to limit the rotation angle of the toggle member 4 and the positioning tooth block 15.

[0075] After the operating handle 4 is pinched and rotated, the locking tooth block 12 moves accordingly until the locking tooth row 13 engages with the positioning tooth row 17, thereby locking the operating handle 4. The reason why the operating handle 4 can be locked after the locking tooth row 13 engages with the positioning tooth row 17 is that since the positioning tooth block 15 is located behind the locking tooth block 12, that is, the positioning tooth block 15 is located at the rear of the handle body 1, the force arm from the positioning shaft 14 of the positioning tooth block 15 to the engagement point is the rear force arm; and the locking tooth block 12 is fixed to the operating handle 4 and the two can be considered as one piece. The rotation axis of this one piece is the handle shaft 5, and the force arm from the handle shaft 5 to the engagement point is the front force arm. Since the handle shaft 5 is located at the front of the operating handle 4, it is obvious that the front force arm is much greater than the rear force arm, and the locking tooth block 12 and the positioning tooth block 15 are in a torque equilibrium state, that is, the force of the locking tooth block 12 attempting to escape the engagement lock is much smaller than the locking force of the positioning tooth block 15, so the operating handle 4 can be locked.

[0076] The unlocking mechanism includes an unlocking lever 21 capable of moving forward and backward within the handle 1. A first return spring 27 is interposed between the unlocking lever 21 and the handle 1. The first return spring 27 forces the unlocking lever 21 to move forward. The rear end of the unlocking lever 21 is aligned with the upper portion of the positioning tooth block 15. When the unlocking lever 21 moves backward, it pushes the positioning tooth block 15 to rotate backward, disengaging the locking teeth 13 from the positioning teeth 17 and achieving unlocking.

[0077] In order to drive the unlocking rod 21 to move backward, an unlocking sliding button 8 is slidably provided on the handle 1, and the unlocking sliding button 8 is exposed on the upper surface of the handle body 1.

[0078] A positioning block 18 is fixed on the handle body 1 . In this embodiment, a positioning shaft 22 is fixedly passed through the positioning block 18 . The positioning block 18 is fixed to the handle body 1 via the positioning shaft 22 .

[0079] The positioning block 18 is provided with a rotatable unlocking plate 23. The lower end of the unlocking plate 23 is rotatably connected to the positioning block 18 via an unlocking plate shaft 24. The upper portion of the unlocking plate 23 is movably connected to the unlocking slide button 8, so that when the unlocking slide button 8 moves backward, it can drive the unlocking plate 23 to rotate around the unlocking plate shaft 24, thereby pushing the unlocking rod 21 to move backward through the unlocking plate 23, and thereby pushing the positioning tooth block 15 to rotate backward through the unlocking rod 21, so that the locking tooth row 13 is disengaged from the positioning tooth row 17 to achieve unlocking. In one embodiment, a groove is provided inwardly on the rear end surface of the positioning block, and the unlocking plate 23 is located in the groove, which is rational and compact in structure. In one embodiment, a push shaft 25 is fixedly penetrated on the unlocking slide button 8, and a through-hole is provided on the upper portion of the unlocking plate 23. The push shaft 25 passes through the through-hole, so that the push shaft 25 can drive the unlocking plate 23 to rotate around the unlocking plate shaft 24.

[0080] In one embodiment, the unlocking rod 21 is provided with a resisting rod 38. When unlocking, the unlocking plate 23 resists the resisting rod 38, thereby pushing the unlocking rod to move backward. In order to reduce wear, a sheath 39 can also be provided on the outer surface of the resisting rod.

[0081] The handle 1 is also provided with a safety mechanism to prevent the unlocking slide button 8 from being misoperated. The safety mechanism includes:

[0082] A safety button 26 is provided on the handle body 1 and can be raised and lowered. The safety button 26 extends from the upper surface of the handle body 1. A second return spring 28 is provided between the safety button 26 and the handle body 1. Under the action of the second return spring 28, the safety button 26 is in a high, locked position. At this time, the safety button 26 can prevent the unlocking slide button 8 from moving backward. After the safety button 26 is pressed downward, the safety button 26 no longer blocks the unlocking slide button 8. In one embodiment, the safety button 26 is located in front of the unlocking slide button 8. The unlocking slide button 8 has a positioning arm 30 extending forward. The positioning arm 30 cooperates with the safety button 26. In one embodiment, the specific cooperation method is as follows:

[0083] A limiting groove 31 is provided on the bottom surface of the positioning arm 30, and a limiting block 32 corresponding to the limiting groove 31 is provided on the safety button 26; when the safety button 26 is in the high locked position under the action of the second return spring 28, the limiting block 32 is located in the limiting groove 31, thereby preventing the unlocking slide button 8 from moving backward; after the safety button 26 is pressed downward, the limiting block 32 disengages from the limiting groove 31, so that the unlocking slide button 8 can move backward smoothly.

[0084] In one embodiment, in order to ensure that the safety button 26 is positioned after being pressed and to facilitate the operation of the unlocking slide button 8 to move backward, a lock tongue 33 that can move forward and backward is further provided in the positioning block 18. The lock tongue 33 has a stop 34 extending forward, and the safety button 26 has a locking shoulder 35 extending backward.

[0085] A third return spring 29 is provided between the lock tongue 33 and the positioning block 18. Under the action of the third return spring 29, the lock tongue 33 extends forward from the positioning block and abuts against the safety button 26. After the safety button 26 is pressed downward, the safety button 26 pushes the lock tongue 33 backward until the locking boss 35 of the safety button is located below the stop 34 of the lock tongue. At this time, the stop 34 blocks the locking boss 35, so that the safety button 26 remains in the low released position so that the safety button 26 no longer blocks the unlocking slide button 8. In one embodiment, in order to enable the lock tongue 33 to be driven back smoothly when the safety button 26 is pressed down, the front end surface of the lock tongue 33 has a first inclined surface 40 tilted backward, and the safety button 26 has a second inclined surface 41 adapted to the first inclined surface 40. Under the action of the third return spring 29, the lock tongue 33 extends forward from the positioning block and the first inclined surface 40 is abutted against the second inclined surface 41 of the safety button 26. When the safety button 26 is pressed down, the lock tongue 33 can be pushed back smoothly under the interaction of the first inclined surface 40 and the second inclined surface 41.

[0086] The unlocking slide button 8 is provided with a downwardly protruding protrusion 36, and the lock tongue 33 has a push groove 37. The protrusion 36 is located in the push groove 37. When the unlocking slide button 8 moves backward to unlock, the protrusion 36 moves to the end of the push groove 37 until it pushes the lock tongue 33, thereby driving the lock tongue 33 to move backward so that the stop 34 of the lock tongue no longer blocks the locking boss 35, so that the safety button 26 rises up under the action of the second return spring 28 and presses on the positioning arm 30.

[0087] And after the unlocking slide button 8 is reset under the action of the first return spring 27, the limit block 32 enters the limit groove 31 again. This completes the whole process of the interlayer narrowing and locking, and the interlayer widening again after unlocking.

A positioning spring is provided at the rear of the positioning tooth block to support the positioning tooth block so that it has a tendency to rotate forward. A positioning tooth row is provided on the front end surface of the positioning tooth block. After pinching the operating handle and rotating it, the locking tooth block moves accordingly until the locking tooth row engages with the positioning tooth row, thereby locking the operating handle; The unlocking mechanism includes: an unlocking rod capable of moving forward and backward in the handle body, a first return spring being provided between the unlocking rod and the handle body, the unlocking rod having a tendency to move forward under the action of the first return spring, and the tail of the unlocking rod being aligned with the upper portion of the positioning tooth block; It is characterized in that the unlocking mechanism further includes: an unlocking slide button slidably disposed on the handle body, and the unlocking slide button is exposed on the upper surface of the handle body; A positioning block is fixed on the handle body, and a rotatable unlocking plate is provided in the positioning block, and the lower end of the unlocking plate is rotatably connected to the positioning block via an unlocking plate rotating shaft, and the upper part of the unlocking plate is movably connected to the unlocking slide button, so that when the unlocking slide button moves backward, it can drive the unlocking plate to rotate around the unlocking plate rotating shaft, thereby pushing the unlocking lever to move backward through the unlocking plate, and then pushing the positioning tooth block to rotate backward through the unlocking lever, so that the locking tooth row is disengaged from the positioning tooth row to achieve unlocking; The handle is also provided with a safety mechanism, which includes: A safety button is provided on the handle body and can be raised and lowered. The safety button extends from the upper surface of the handle body. A second return spring is provided between the safety button and the handle body. Under the action of the second return spring, the safety button is in a high locked position. The safety button can prevent the unlocking slide button from moving backward; after the safety button is pressed downward, the safety button no longer blocks the unlocking slide button.

2. The detachable pot handle according to claim 1, characterized in that: The safety button is located in front of the unlocking slide button. The unlocking slide button has a positioning arm extending forward, and the positioning arm cooperates with the safety button.

3. The detachable pot handle according to claim 2, characterized in that: A limiting groove is provided on the bottom surface of the positioning arm, and a limiting block corresponding to the limiting groove is provided on the safety button; When the safety button is in the high locked position under the action of the second return spring, the limit block is located in the limit groove, thereby preventing the unlocking slide button from moving backward; when the safety button is pressed downward, the limit block disengages from the limit groove.

4. The detachable pot handle according to claim 3, wherein: The positioning block is also provided with a lock tongue that can move forward and backward, the lock tongue has a stop extending forward, and the safety button has a locking shoulder extending backward; A third return spring is provided between the lock tongue and the positioning block. Under the action of the third return spring, the lock tongue extends forward from the positioning block and abuts against the safety button. When the safety button is pressed downward, the safety button pushes the lock tongue backward until the locking protrusion of the safety button is located below the stopper of the lock tongue. At this time, the stopper blocks the locking protrusion, so that the safety button remains in the low released position so that the safety button no longer blocks the unlocking slide button. The unlocking slide button is provided with a downwardly protruding protrusion, and the lock tongue has a push groove, in which the protrusion is located. When the unlocking slide button is moved backward to unlock, the protrusion moves to the end of the push groove until it pushes the lock tongue, thereby driving the lock tongue to move backward, so that the stop of the lock tongue no longer blocks the locking shoulder, so that the safety button rises up under the action of the second return spring and presses against the positioning arm; After the unlocking slide button is reset under the action of the first reset spring, the limiting block enters the limiting groove again.

5. The detachable pot handle according to claim 4, characterized in that: The front end face of the lock tongue has a first inclined surface tilted backward, and the safety button has a second inclined surface adapted to the first inclined surface.
