Description
Technical Field
[0001] This utility model relates to a pot handle, specifically a detachable handle that is easy to operate and safe to use. Background Technology
[0002] A pot is a cooking utensil used for various cooking methods such as boiling, frying, and stir-frying. A pot typically consists of a body, a lid, and a handle. Traditionally, the handle is riveted (or screwed) to the outside of the pot body, leaving rivet heads on the side. This allows oil to accumulate on the rivet heads during cooking, leading to rust over time and making cleaning difficult. Furthermore, riveting (or screwing) requires punching holes in both the pot body and the handle, which is inconvenient and can cause stripping and loosening after assembly. Some pots use spot welding to directly fix the handle to the pot body, providing a secure connection, but the handle cannot be removed, resulting in a large pot size and making packaging and transportation inconvenient. To address this, detachable handles have emerged for easy removal. However, most detachable handles on the market use lever-driven, rack-and-pinion locking, or knob-driven mechanisms for gripping. A common problem with these products is the large number of parts and complex transmission mechanisms; a problem with a single component can cause the entire product to malfunction.
[0003] Upon investigation, the existing Chinese patent with patent number CN202411314129.X, entitled "A Detachable Handle with Quick Clamping and Self-Locking Function," includes a handle body and a clamping piece. The handle body includes a handle base and a handle cover. A connecting seat is recessed at the front of the upper surface of the handle base. The front end of the handle cover has a connecting head corresponding to the connecting seat. The connecting head and the connecting seat are rotatably connected through front and rear transmission connectors. The clamping piece is located at the front of the upper surface of the handle base. The rear end of the clamping piece is fixed to the front transmission connector. The handle cover is provided with a safety lock that locks with the handle base. When the handle cover is closed with the handle base, the clamping piece is clamped to the front end of the handle base, the front and rear transmission connectors are in a self-locking position, and the safety lock is locked with the handle base. When the safety lock is opened and the rear end of the handle cover is lifted, the self-locking of the front and rear transmission connectors is released, and the clamping piece is lifted and released from clamping. The handle has a firm grip and fits well with the pot rim, but the handle body consists of a handle base and a handle cover, which are many parts and difficult to manufacture. The handle cover needs to be lifted during operation, which is not convenient. In addition, the safety of the safety lock also needs further improvement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a detachable handle that is simpler and more reasonable in structure, more convenient to operate, and safer and more reliable in use.
[0005] The technical solution of this utility model to solve the technical problem is as follows: A detachable handle includes a handle body and a clamping piece. A mounting groove is formed on the front part of the upper surface of the handle body. An upper pressure plate is provided on the mounting groove. The upper pressure plate and the mounting groove are movably connected by a front linkage block and a rear linkage block. The clamping piece is disposed on the front part of the upper surface of the handle body, and the rear end of the clamping piece is fixed to the front linkage block. The characteristic feature is that a locking base is provided on the upper surface of the handle body and the rear side of the upper pressure plate. A lever lock that can rotate back and forth is provided on the front side of the lower end of the locking base. The upper pressure plate contains... It has a locking tongue that extends backward and engages with the lever lock to lock. The lock base has a knob button that can drive the lever lock and the locking tongue to lock or unlock. When the lever lock and the locking tongue are locked, the clamping plate and the front end of the handle body are clamped, and the front linkage block and the rear linkage block are in the self-locking position. If the knob button is in the locked position at this time, the knob button cannot be pressed. If the knob button is rotated to the open position, pressing the knob button will unlock the lever lock and the locking tongue. At this time, the upper pressure plate is lifted, the front linkage block and the rear linkage block are in the self-locking released state, and the clamping plate can be released from clamping.
[0006] As an improvement, the mounting groove has a U-shaped concave surface, and the shape and width of the upper pressure plate correspond to the mounting groove. The upper end of the front linkage block is rotatably connected to the top front end of the upper pressure plate through a shaft pin, and the lower end is set at the front end of the mounting groove and rotatably connected to the shaft pin. The upper end of the rear linkage block is rotatably connected to the bottom of the upper pressure plate through a shaft pin, and the lower end is set at the rear end of the mounting groove and rotatably connected to the shaft pin. When the upper pressure plate is closed with the handle body, the upper shaft hole of the front linkage block and the upper shaft hole and lower shaft hole of the rear linkage block form an angle of 170 to 180 degrees, forming a dead point state.
[0007] Furthermore, a U-shaped mounting groove is formed on the upper surface of the handle body and the rear side of the mounting groove. The locking base is set in the U-shaped mounting groove. A mounting hole for inserting the knob button is opened longitudinally through the locking base. An opening for the lever locking is opened at the front. The knob button is installed in the mounting hole in a limited rotational manner by a metal pin. A return spring is supported at the bottom of the knob button, so that the knob button always has the tendency to pop up.
[0008] Furthermore, the knob button has a horizontally oriented pin hole in the middle for a metal pin to pass through. The mounting hole of the locking base has a partial annular groove for the two ends of the metal pin to be inserted and rotated 90°. One end of the partial annular groove has a downward longitudinal opening. When the knob button is in the locked position, the metal pin rests in the partial annular groove and the knob button cannot be pressed. When the knob button is rotated to the open position, the metal pin is in the longitudinal opening position and the knob button can be pressed.
[0009] Furthermore, the bottom front end of the U-shaped mounting groove is formed with a mounting slot for installing the lever lock. The lever lock includes an integrally formed front plate, vertical plate, and rear plate. The inner ends of the front plate, vertical plate, and rear plate are connected to form an integral structure. The included angle between the front plate and the rear plate is 120-150°. 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 lock that cooperates with the latch. The upper end of the rear plate is folded backward to form a folded part that cooperates with the knob button. The left and right ends of the lever lock have protruding parts. The rotating shaft has corresponding shaft holes on both sides of the U-shaped mounting groove. The lever lock can be installed in the U-shaped mounting groove by the cooperation of the rotating shaft and the shaft holes or directly flipped back and forth. When the knob button is in the locked position, the back plate of the lever lock abuts against the upper limit block on the lower outer wall of the knob button, and the lever lock locks with the latch. When the knob button is rotated 90° to the open position, the metal pin is located above the back plate of the lever lock. Pressing the knob button will make the lever lock rotate backward and disengage from the latch.
[0010] Furthermore, the upper pressure plate is provided with a mounting cavity for the locking tongue to move back and forth in a limited manner. The rear end of the mounting cavity is provided with an opening for the locking tongue to extend out. A spring is provided in the mounting cavity to abut against the tail of the locking tongue, so that the locking tongue always tends to extend backward and lock with the lever lock.
[0011] Furthermore, the front end of the handle body is formed as an outward and downward inclined surface, the front end of the clamping piece is a corresponding cut surface, and a silicone chuck is fitted on the front end of the clamping piece. The rear end of the clamping piece is formed as a connecting piece with an inverted U-shaped upper end, and the upper end of the front linkage block is provided with an inverted U-shaped groove and is fixed to the connecting piece by screws.
[0012] Furthermore, the lower end of the front linkage block is rotatably connected to the mounting groove via a shaft pin, and a torsion spring is sleeved on the shaft pin, so that the front linkage block always has the tendency to rotate backward to open the clamping piece.
[0013] Furthermore, a fireproof ring is fitted onto the bottom front end of the handle body. The fireproof ring is fitted onto the handle body by a snap-fit and fixed by screws.
[0014] Finally, the handle body has an opening at the rear end and a recessed hollow part, a tail plug at the opening, and a hanging hole at the rear end of the handle body for easy hanging.
[0015] Compared with existing technologies, the advantages of this utility model are: further simplification of the structure, elimination of the handle cover, and the use of an upper pressure plate and clamping plate in conjunction, along with the addition of a locking tongue, lever lock, and knob button, making the clamping more secure and stable, while preventing the handle from loosening due to accidental collisions during daily use, providing a double safety function. This utility model has a simpler and more reasonable structure, fewer parts, and is easier to operate, not only reducing product manufacturing costs but also increasing safety. Furthermore, compared with similar products on the market, it has a higher adaptability to pot rims, capable of clamping not only pots but also plates, wide-rimmed pans for frying, etc. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] like Figures 1-9As shown, a detachable handle includes a handle body 1 and a clamping piece 2. A mounting groove 12 is formed on the front of the upper surface of the handle body 1. An upper pressure plate 3 is provided on the mounting groove 12. The upper pressure plate 3 and the mounting groove 12 are movably connected via a front linkage block 7 and a rear linkage block 8. The clamping piece 2 is located on the front of the upper surface of the handle body 1, and its rear end is fixed to the front linkage block 7. A locking base 60 is provided on the upper surface of the handle body 1 and the rear side of the upper pressure plate 3. A lever lock 6, which can rotate back and forth, is provided on the front side of the lower end of the locking base 60. A rearwardly extending lever lock 6 is provided within the upper pressure plate 3. The locking tongue 5 and the locking base 60 are equipped with a knob button 4 that can drive the lever lock 6 and the locking tongue 5 to lock or unlock. When the lever lock 6 and the locking tongue 5 are locked, the clamping piece 2 and the front end of the handle body 1 are clamped, and the front linkage block 7 and the rear linkage block 8 are in the self-locking position. If the knob button 4 is in the locked position at this time, the knob button 4 cannot be pressed. If the knob button 4 is rotated to the open position, the knob button 4 can be pressed to unlock the lever lock 6 and the locking tongue 5. At this time, the upper pressure plate 3 is lifted, the front linkage block 7 and the rear linkage block 8 are in the self-locking released state, and the clamping piece 2 can be released from clamping.
[0027] The specific structure is as follows: the mounting groove 12 has a U-shaped concave surface. Front shaft holes 121 and rear shaft holes 122 are distributed on the inner walls of the front and rear portions of the mounting groove 12. The shape and width of the upper pressure plate 3 correspond to the mounting groove 12. Front shaft holes 31 and lower shaft holes 32 are respectively arranged at the front and lower ends of the upper pressure plate 3. Upper shaft holes 71 and lower shaft holes 72 are distributed at both ends of the front linkage block 7. Upper shaft holes 81 and lower shaft holes 82 are distributed at both ends of the rear linkage block 8. The upper shaft hole 71 of the front linkage block 7 is rotatably connected to the top front shaft hole 31 of the upper pressure plate 3 via a shaft pin 30. The lower end of the front linkage block 7 is located at the front end of the mounting groove 12, allowing the lower shaft hole 72 of the front linkage block 7 to connect to the front end of the mounting groove 12 via the shaft pin 30. The upper shaft hole 81 of the rear linkage block 8 is rotatably connected to the lower shaft hole 32 at the bottom of the upper pressure plate 3 via a shaft pin 30. The lower end of the rear linkage block 8 is located 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 to the rear shaft hole 122 of the mounting groove 12 via a shaft pin 30. Thus, when the upper pressure plate 3 is closed 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 lower shaft hole 82 of the rear linkage block 8 form an angle of 170 to 180°, preferably 180°, forming a dead point self-locking state. The closing angle formed by the front linkage block 7 and the rear linkage block 8 is 30 to 70°. The upper surface of the handle body 1 and the rear side of the mounting groove 12 are formed with a U-shaped mounting groove 13. The locking base 60 is set in the U-shaped mounting groove 13 and fixed to the handle body 1 by screws. The locking base 60 has a longitudinal through-hole 601 for inserting the knob button 4. The front has an opening for the lever lock 6 to move. The knob button 4 can be rotatably installed in the through-hole 601 by metal pin 4a. The bottom of the knob button 4 is supported by a return spring 40, so that the knob button 4 always has the tendency to pop up, so that it can move up and down. The knob button 4 has a horizontally oriented pin hole in the middle for the metal pin 4a to pass through. A limit block 4b is provided on the outer wall of the knob button 4 at a 90° offset position below the metal pin 4a. The mounting hole 601 of the locking base 60 has a partial annular groove 602 for the two ends of the metal pin 4a to be inserted and rotated horizontally by 90°. That is, the partial annular groove 602 corresponds to a fan angle of 90°. One end of this partial annular groove 602 has a downward longitudinal opening 603. When the knob button 4 is in the locked position, the metal pin 4a rests in the partial annular groove and the knob button 4 cannot be pressed. When the knob button 4 is rotated to the open position, the metal pin 4a is in the longitudinal opening position and the knob button 4 can be pressed.
[0028] The bottom front end of the U-shaped mounting groove 13 has a mounting slot 131 for mounting the lever lock 6. The lever lock 6 includes an integrally formed front plate 61, a vertical plate 63, and a rear plate 62. The inner ends of the front plate 61, the vertical plate 63, and the rear plate 62 are connected to form an integral structure. The included angle between the front plate 61 and the rear plate 62 is 120-150°. 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 lock that cooperates with the latch 5. The upper end of the rear plate 62 is folded backward to form a folded part that cooperates with the knob button 4. The left and right ends of the lever lock 6 have protruding pivots 64. The two sides of the bottom front end of the U-shaped mounting groove 13 have corresponding pivot holes. The lever lock 6 can be installed in the mounting slot 131 by rotating the pivot 64 and the pivot holes. Of course, the lever lock 6 can also be directly set at the front of the bottom of the U-shaped mounting groove 13 using the pivot 64, with a similar effect. When the knob button 4 is in the locked position, the rear plate of the lever lock 6 abuts against the upper limit block 4b on the lower outer wall of the knob button 4, and the latch of the lever lock 6 engages with the latch tongue 5 for locking. When the knob button 4 is rotated 90° to the open position, the metal pin 4a is positioned above the rear plate 62 of the lever lock 6, and the lower limit block 4b has been removed. Pressing the knob button 4 will cause the lever lock 6 to rotate backward and disengage from the latch tongue 5. The upper pressure plate 3 has a mounting cavity 33 for the latch tongue 5 to move back and forth. The rear end of the mounting cavity 33 has an opening for the latch tongue 5 to extend. The mounting cavity 33 has a spring 50 that abuts against the tail of the latch tongue 5, so that the latch tongue 5 always tends to extend backward and lock with the lever lock 6. The front end of the mounting cavity 33 has a plug 501. The front end of the handle body 1 is formed as an outward and downward inclined surface, and the front end of the clamping piece 2 is a corresponding cut surface. A silicone chuck 21 is fitted onto the front end of the clamping piece 2, and the rear end of the clamping piece 2 is formed as a connecting piece 22 with an inverted U-shaped upper end. The upper end of the front linkage block 7 is provided with an inverted U-shaped groove and is fixed to the connecting piece 22 by screws. The lower end of the front linkage block 7 is rotatably connected to the mounting groove 12 through a shaft pin 30. A torsion spring 70 is fitted on the shaft pin 30, so that the front linkage block 7 always has the tendency to rotate backward to open the clamping piece 2.
[0029] A fireproof ring 9 is fitted onto the bottom front end of the handle body 1. The fireproof ring 9 is fitted onto the handle body 1 by a snap-fit and fixed by screws. The rear end of the handle body 1 is open and has a recessed hollow part. A tail plug 10 is provided at the opening. A hanging hole 11 is provided at the rear end of the handle body 1 for easy hanging.
[0030] The specific operation process is as follows:
[0031] In the locked state, such as Figure 1 , 23. When the upper pressure plate 3 is pressed down, it causes the locking tongue 5 to lock with the lever lock 6. At this time, the rear plate of the lever lock 6 abuts against the upper limit block 4b on the lower outer wall of the knob button 4, and the lever lock 6 is in a locked state. When the knob button 4 is rotated to the locked position, 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 the front end bears, the rear end does not bear the torque in the opening direction. During use, even if you let go, the handle will not fall off.
[0032] To unlock, rotate knob button 4 90° to the open position, as shown. Figure 4 , 5 At this point, the metal pin 4a is positioned 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 down, causing the metal pin 4a to depress, resulting in the lever lock 6 rotating backward. The locking tongue 5 separates from the lever lock 6. At this time, the torsion spring 70 releases its potential energy, causing the upper pressure plate 3 to spring open, breaking the dead-point state formed by the front linkage block 7 and the rear linkage block 8. The clamping plate 2 can then be flipped upward, completing the opening process. Figure 6 .
[0033] When in an abnormal locked position, press down the upper pressure plate 3 directly. The bolt will retract due to the pressure until it reaches the locked position and then pops out, locking with the lever lock 6. Figure 7 .
[0034] This embodiment has fewer parts and is easy to operate, which not only reduces the product manufacturing cost, but also increases the safety of use because it requires two operation actions, such as rotating and pressing the knob button 4, to open the latch. Compared with similar products on the market, it has a higher compatibility with the edge of the pot, and can not only hold pots, but also plates, pan-frying pans, etc.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
