Description

Technical Field

[0001] The present invention relates to a pot handle, specifically a detachable handle that is convenient to operate and safe and reliable to use. Background Art

[0002] A pot is a cooking utensil that can be used for various cooking operations such as cooking, boiling, frying, and stir-frying food. Pots basically include a pot body, a pot lid, and a handle. Traditional handles are riveted (or screwed) to the outside of the pot body through rivets (or screws). In this way, there will be rivet heads left on the side of the pot body. During cooking, oil stains will accumulate at the rivet heads, which is prone to rusting over time and is not easy to clean. Moreover, when using rivets (or screws) for connection, holes need to be punched in the pot body and the pot handle, which is very inconvenient for processing, and it is also prone to slipping teeth and loosening after assembly. There are also cases where the handle is directly fixed to the pot body by spot welding. Although the connection is firm, the handle cannot be disassembled, making the pot large in size and not conducive to packaging and transportation. For this reason, detachable handles have emerged currently, which are convenient to detach. However, the clamping actions of detachable handles on the market basically adopt the methods of rod drive, rack locking, or knob drive. The common problem of the products is that there are too many parts and the transmission mechanism is complex. If a single component has a problem, it may cause the entire product to fail.

[0003] After investigation, the existing Chinese patent "A Detachable Handle with Quick Clamping and Self-Locking Function" with the patent number CN202411314129.X includes a handle main body and a clamping piece. The handle main body includes a handle base and a handle upper cover. A connecting seat is recessed in the front part of the upper surface of the handle base. The front end of the handle upper cover has a connector corresponding to the connecting seat. The connector and the connecting seat are rotationally connected through front and rear transmission connectors. The clamping piece is arranged at the front part of the upper surface of the handle base. The rear end of the clamping piece is fixed to the front transmission connector. An insurance lock for locking with the handle base is arranged on the handle upper cover. When the handle upper cover and the handle base are closed, the clamping piece and the front end of the handle base are in a clamping state, the front and rear transmission connectors are in a self-locking position, and the insurance lock is locked with the handle base. When the insurance lock is opened and the rear end of the handle upper cover is lifted, the self-locking of the front transmission connector and the rear transmission connector is released, and the clamping piece is lifted to release the clamping. This handle has a firm clamping and a high adaptability to the pot edge. However, the handle main body includes a handle base and a handle upper cover, with many parts, troublesome processing, and it is not convenient to operate as it requires lifting the handle upper cover, and the safety of the insurance lock also needs to be further improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detachable handle with a simpler and more reasonable structure, more convenient operation, and safe and reliable use.

[0005] The technical solution for the present invention to solve the technical problem is as follows: A detachable handle, comprising a handle body and a clamping piece. An installation groove is formed at the front part of the upper surface of the handle body. An upper pressure plate is provided on the installation groove. The upper pressure plate and the installation groove are movably connected through a front linkage block and a rear linkage block. The clamping piece is arranged at the front part of the upper surface of the handle body. The rear end of the clamping piece is fixed to the front linkage block. It is characterized in that: A lock base is provided at the rear side of the upper surface of the handle body and the upper pressure plate. A lever lock that can rotate back and forth is provided at the front side of the lower end of the lock base. A lock tongue that extends backward and cooperates with the lever lock for locking is arranged in the upper pressure plate. A knob button that can drive the lever lock to lock or unlock with the lock tongue is arranged in the lock base. When the lever lock is locked with the lock tongue, the clamping piece and the front end of the handle body are in a clamping state, and the front linkage block and the rear linkage block are in a self-locking position. If the knob button is in the locked gear at this time, the knob button cannot be pressed. If the knob button is rotated to the open gear, pressing the knob button can unlock the lever lock and the lock tongue. At this time, the upper pressure plate is lifted, the front linkage block and the rear linkage block are in a self-locking release state, and the clamping piece can be loosened and clamped.

[0006] As an improvement, the installation groove presents a U-shaped concave surface. The shape and width of the upper pressure plate correspond to the installation groove. The upper end of the front linkage block is rotatably connected to the top of the front end of the upper pressure plate through a pin, and the lower end is arranged at the front end of the installation groove and rotatably connected through a pin. The upper end of the rear linkage block is rotatably connected to the bottom of the upper pressure plate through a pin, and the lower end is arranged at the rear end of the installation groove and rotatably connected through a pin. When the upper pressure plate is covered with the handle body, the upper shaft holes of the front linkage block, the upper shaft holes and the lower shaft holes of the rear linkage block form an angle of 170-180°, forming a dead point state.

[0007] Furthermore, a U-shaped installation groove that is connected is formed at the rear side of the upper surface of the handle body and the installation groove. The lock base is arranged in the U-shaped installation groove. An installation hole for the knob button to be placed is longitudinally penetrated in the lock base. An opening for the lever lock to move is opened at the front part. The knob button is installed in the installation hole through a metal pin in a limited rotation manner. A return spring supports the bottom of the knob button, so that the knob button has a tendency to always pop up upward.

[0008] Still further, a pin hole for the metal pin to pass through is horizontally opened in the middle of the knob button. A partial annular groove hole for the two ends of the metal pin to be placed and rotated by 90° is arranged in the installation hole of the lock base. A longitudinal opening downward is opened at one end of the partial annular groove hole. When the knob button is in the locked gear, the metal pin is placed in the partial annular groove hole, and the knob button cannot be pressed. When the knob button is rotated to the open gear, the metal pin is in the longitudinal opening position, and the knob button can be pressed.

[0009] Furthermore, an installation notch for installing the lever latch is formed at the front end of the bottom of the U-shaped installation groove. The lever latch includes a front plate, a vertical plate, and a rear plate that are integrally formed. The inner ends of the front plate, the vertical plate, and the rear plate are connected into an integral structure. The included angle between the front plate and the rear plate is 120° to 150°. The vertical plate is located between the front plate and the rear plate and is perpendicular to the front plate. The upper end of the vertical plate is folded forward to form a latch that cooperates with the lock tongue. The upper end of the rear plate is folded backward to form a folding portion that cooperates with the knob button. The left and right ends of the lever latch are convexly provided with rotating shafts. Corresponding shaft holes are provided on both sides of the U-shaped installation groove. The lever latch is installed in the U-shaped installation groove in a manner that can be turned forward and backward through the cooperation of the rotating shaft and the shaft hole or directly. When the knob button is in the locked position, the rear plate of the lever latch abuts against and positions the limiting block on the lower outer wall of the knob button, and the latch of the lever latch cooperates with the lock tongue to lock. When the knob button is rotated 90° to the open position, the metal pin is located above the rear plate of the lever latch, and pressing the knob button can cause the lever latch to rotate backward and disengage from the lock tongue.

[0010] Furthermore, an installation cavity for the front and rear limit movement of the lock tongue is provided inside the upper pressure plate. An opening for the lock tongue to extend out is provided at the rear end of the installation cavity. A spring that abuts against the tail of the lock tongue is provided inside the installation cavity, so that the lock tongue has a tendency to always extend backward and lock with the lever latch.

[0011] Furthermore, the front end of the handle body is formed into an inclined surface that slopes outward and downward. The front end of the clamping piece is a corresponding cut surface, and a silicone chuck is sleeved on the front end of the clamping piece. The rear end of the clamping piece is formed into a connecting piece with an inverted U-shaped upper end. The upper end of the front linkage block is fixed to the connecting piece through a screw in the inverted U-shaped groove.

[0012] Furthermore, the lower end of the front linkage block is rotationally connected to the installation groove through a shaft pin, and a torsion spring is sleeved on the shaft pin, so that the front linkage block has a tendency to always rotate backward to open the clamping piece.

[0013] Furthermore, a fireproof ring is sleeved on the bottom of the front end of the handle body. The fireproof ring is sleeved on the handle body by means of a buckle and fixed by screws.

[0014] Finally, the rear end of the handle body is open and provided with a concave hollow portion. A tail plug is provided at the opening, and a hanging hole for easy hanging is provided at the rear end of the handle body.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The structure is further simplified by canceling the handle upper cover. The upper pressing plate is used in cooperation with the clamping piece, and at the same time, a locking tongue, a lever lock and a knob button are provided, making the clamping more firm and stable. At the same time, it avoids the handle from loosening due to accidental collision during daily use, playing a double-insurance role. The structure of the present invention is simpler and more reasonable, with fewer parts and convenient operation. It not only reduces the manufacturing cost of the product, but also increases the use safety. And compared with similar products on the market, it has a higher adaptability to the pot edge.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Such as Figures 1 to 9As shown in the figure, a detachable handle includes a handle body 1 and a clamping piece 2. A mounting groove 12 is formed at the front part of the upper surface of the handle body 1. An upper pressure plate 3 is arranged on the mounting groove 12. The upper pressure plate 3 and the mounting groove 12 are movably connected through a front linkage block 7 and a rear linkage block 8. The clamping piece 2 is arranged at the front part of the upper surface of the handle body 1. The rear end of the clamping piece 2 is fixed to the front linkage block 7. A lock base 60 is arranged at the rear side of the upper surface of the handle body 1 and the rear side of the upper pressure plate 3. A lever lock 6 that can rotate back and forth is arranged at the front side of the lower end of the lock base 60. A lock tongue 5 that extends backward and cooperates with the lever lock 6 for locking is arranged in the upper pressure plate 3. A knob button 4 that can drive the lever lock 6 to lock or unlock with the lock tongue 5 is arranged in the lock base 60. When the lever lock 6 is locked with the lock tongue 5, the clamping piece 2 and the front end of the handle body 1 are in a clamping state, and the front linkage block 7 and the rear linkage block 8 are in a self-locking position. If the knob button 4 is in the locked gear at this time, the knob button 4 cannot be pressed. If the knob button 4 is rotated to the open gear, the knob button 4 can be pressed, and the unlocking of the lever lock 6 and the lock tongue 5 can be realized. At this time, the upper pressure plate 3 is lifted, the front linkage block 7 and the rear linkage block 8 are in a self-locking release state, and the clamping piece 2 can be loosened and clamped.

[0027] The specific structure is as follows: the mounting groove 12 presents a U-shaped concave surface, and the mounting groove 12 is provided with a front shaft hole 121 and a rear shaft hole 122 on the inner wall of the front and rear parts. The shape and width of the upper pressing plate 3 correspond to the mounting groove 12. The front end and the lower end of the upper pressing plate 3 are respectively provided with a front shaft hole 31 and a lower shaft hole 32. The upper and lower ends of the front linkage block 7 are provided with an upper shaft hole 71 and a lower shaft hole 72. The upper and lower ends of the rear linkage block 8 are provided with an upper shaft hole 81 and a lower shaft hole 82. The upper shaft hole 71 of the front linkage block 7 is rotatably connected with the top front shaft hole 31 of the upper pressing plate 3 through an axle pin 30. The lower end of the front linkage block 7 is arranged at the front end of the mounting groove 12, so that the lower shaft hole 72 of the front linkage block 7 passes through the axle pin 30 and the front end of the mounting groove 12. The upper shaft hole 121 is rotatably connected, the upper shaft hole 81 of the rear linkage block 8 is rotatably connected with the bottom lower end shaft hole 32 of the upper pressure plate 3 through the shaft pin 30, and the lower end of the rear linkage block 8 is arranged at the rear end of the mounting groove 12, so that the lower shaft hole 82 of the rear linkage block 8 is rotatably connected with the rear shaft hole 122 of the mounting groove 12 through the shaft pin 30. In this way, when the upper pressure plate 3 is covered with the handle body 1, the front linkage block 7 is in a vertical state and the rear linkage block 8 is in an inclined state. The upper shaft hole 71 of the front linkage block 7 and the upper shaft hole 81 and the lower shaft hole 82 of the rear linkage block 8 are at an angle of 170 to 180°, preferably an angle of 180°, forming a dead point self-locking state, and the closing angle formed by the front linkage block 7 and the rear linkage block 8 is 30 to 70°. A connected U-shaped mounting groove 13 is formed on the upper surface of the handle body 1 and the rear side of the mounting groove 12. The lock base 60 is arranged in the U-shaped mounting groove 13 and fixed to the handle body 1 by screws. A mounting hole 601 for inserting the knob button 4 is longitudinally penetrated in the lock base 60, and an opening for the lever lock 6 to move is opened at the front. The knob button 4 can be rotatably installed in the penetrating mounting hole 601 by a metal pin 4a at 90°. The bottom of the knob button 4 is supported by a return spring 40, so that the knob button 4 has a tendency to always pop up, so that it can move up and down. A pin hole for the metal pin 4a to pass through is horizontally opened in the middle of the knob button 4, and a limit block 4b is set on the outer wall of the knob button 4 at a 90° position below the metal pin 4a. A local annular groove 602 is provided in the mounting hole 601 of the lock base 60 for the two ends of the metal pin 4a to be inserted and rotated horizontally 90°, that is, the local annular groove 602 corresponds to a fan-shaped angle of 90°, and a downward longitudinal opening 603 is opened at one end of the local annular groove 602. When the knob button 4 is in the locking position, the metal pin 4a is placed in the local annular groove, and the knob button 4 cannot be pressed. When the knob button 4 is rotated to the opening position, the metal pin 4a is in the longitudinal opening position, and the knob button 4 can be pressed.

[0028] At the front end of the bottom of the U-shaped mounting groove 13, there is a mounting notch 131 for mounting the lever latch 6. The lever latch 6 includes a front plate 61, a vertical plate 63, and a rear plate 62 that are integrally formed. The inner ends of the front plate 61, the vertical plate 63, and the rear plate 62 are connected into an integral structure. The included angle between the front plate 61 and the rear plate 62 is 120° to 150°. The vertical plate 63 is located between the front plate 61 and the rear plate 62 and is perpendicular to the front plate 61. The upper end of the vertical plate 63 is folded forward to form a latch that cooperates with the lock tongue 5. The upper end of the rear plate 62 is folded backward to form a folded portion that cooperates with the knob button 4. The left and right ends of the lever latch 6 are protruded with rotating shafts 64. On both sides of the front end of the bottom of the U-shaped mounting groove 13, there are corresponding shaft holes. The lever latch 6 can be installed in the mounting notch 131 in a front-back flipping manner through the cooperation of the rotating shafts 64 and the shaft holes. Of course, the lever latch 6 can also be directly arranged at the front part of the bottom of the U-shaped mounting groove 13 by using the rotating shafts 64, and the effect is similar. When the knob button 4 is in the locked gear position, the rear plate of the lever latch 6 abuts and positions against the upper limit block 4b on the lower outer wall of the knob button 4, and the latch of the lever latch 6 cooperates with the lock tongue 5 to lock. When the knob button 4 rotates 90° to the open gear position, the metal pin 4a is located above the rear plate 62 of the lever latch 6, and the lower limit block 4b has been removed. Pressing the knob button 4 can cause the lever latch 6 to rotate backward and disengage from the lock tongue 5. Inside the upper pressing plate 3, there is a mounting cavity 33 for the front-back limiting movement of the lock tongue 5. The rear end of the mounting cavity 33 is provided with an opening for the lock tongue 5 to protrude. Inside the mounting cavity 33, there is a spring 50 that abuts against the tail of the lock tongue 5, so that the lock tongue 5 has a tendency to always protrude backward and lock with the lever latch 6. The front end of the mounting cavity 33 is provided with a plug 501. The front end of the handle body 1 is formed into an inclined surface that slopes outward and downward. The front end of the clamping piece 2 is a corresponding cutting surface. The front end of the clamping piece 2 is sleeved with a silica gel chuck 21. The rear end of the clamping piece 2 is formed into a connecting piece 22 with an inverted U-shaped upper end. The upper end of the front linkage block 7 is fixed to the connecting piece 22 through a screw in an inverted U-shaped groove. The lower end of the front linkage block 7 is rotatably connected to the mounting groove 12 through a pin 30. A torsion spring 70 is sleeved on the pin 30, so that the front linkage block 7 has a tendency to always rotate backward to open the clamping piece 2.

[0029] A fireproof ring 9 is sleeved on the bottom of the front end of the handle body 1. The fireproof ring 9 is sleeved on the handle body 1 by means of a buckle and fixed by screws. The rear end of the handle body 1 is open and provided with a concave hollow part. A tail plug 10 is provided at the opening. A hanging hole 11 for easy hanging is provided at the rear end of the handle body 1.

[0030] The specific operation process is as follows:

[0031] In the locked state, such as Figure 1 、 2When the upper pressing plate 3 presses downwards, it drives the locking tongue 5 to lock with the lever lock 6. At this time, the rear plate of the lever lock 6 abuts and positions against the upper limiting block 4b on the lower outer wall of the knob button 4, and the lever lock 6 is in a locked state. Rotate the knob button 4 to the locking gear position, and the front linkage block 7 and the rear linkage block 8 form a dead point and are in a self-locking state. No matter how much pressure is applied at the front end, there is no moment in the opening direction at the rear end. During use, even if the hand is released, the handle will not fall off.

[0032] When unlocking is required, rotate the knob button 4 by 90° to the opening gear position, as Figure 4 、 5 shown. At this time, the metal pin 4a is located above the rear plate 62 of the lever lock 6, and the lower limiting block 4b has been removed. The knob button 4 can be pressed downwards. The metal pin 4a presses downwards, causing the lever lock 6 to rotate backwards, and the locking tongue 5 is separated from the lever lock 6. At this time, the torsion spring 70 releases its potential energy, and the upper pressing plate 3 bounces open, destroying the dead point state formed by the front linkage block 7 and the rear linkage block 8. The clamping piece 2 can be turned upwards to complete the opening, as Figure 6 .

[0033] When in an abnormal locking position, directly press down the upper pressing plate 3. At this time, the locking tongue retracts backwards due to the pressing force until it pops out after reaching the locking position and completes the locking with the lever lock 6, as Figure 7 .

[0034] This embodiment has few parts and is convenient to operate. It not only reduces the manufacturing cost of the product, but also, because two operating actions such as rotating and pressing down the knob button 4 are required to unlock the locking tongue, it increases the use safety. And compared with similar products on the market, it has a higher adaptability to the pot edge. It can not only clamp cookware, but also clamp plates, wide-edge pans for pan-frying, etc.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
