[0036] Reference Figure 1-Figure 19 A method for disassembling and assembling a detachable cookware handle. The detachable cookware handle 4 includes a handle body 5, a locking plate assembly, and a fastener 6.

[0037] The handle body 5 is provided with a slot 7 along its length direction, and the slot 7 extends to the front end surface of the handle body 5 to form an insertion opening at the front end surface of the handle body 5 . The slot 7 has a raised spring step 8 .

[0038] The lock plate assembly includes a fixed lock plate 9, a movable lock plate 10, a slide button 11, and a spring 12. The movable lock plate 10 is slidably arranged on the fixed lock plate 9, the slide button 11 is fixed on the movable lock plate 10, and the front end of the spring 11 is against the movable lock plate 10. In one embodiment, a slide groove 13 is provided on the fixed lock plate 9, and the movable lock plate 10 is located in the slide groove 13, so that the movable lock plate 10 can slide forward and backward. In one embodiment, a raised bump 14 is provided on the upper surface of the movable lock plate 10, and an embedding groove is provided on the slide button 11, and the bump 14 is embedded in the embedding groove so that the slide button 11 is fixed on the movable lock plate 10.

[0039] When fitting the described removable cookware handle: The lock plate assembly is inserted into the slot 7 through the insertion port. The front portion of the fixed lock plate 9 extends out of the front end of the handle body 5, and the head of the fixed lock plate 9 is bent downward to form a lower folding plate 15, and the front end of the lower folding plate 15 further extends forward to form a stop plate 16. The rear end of the fixed lock plate 9 abuts against the rear end surface of the slot 7, so that the fixed lock plate 9 is limited in the backward direction. In one embodiment, the width of the slot 7 narrows from front to back, and the width of the fixed lock plate 9 also narrows from front to back to match the slot 7, so that the fixed lock plate 9 can be more firmly positioned in the left and right directions after being inserted into the slot 7.

[0040] After the lock plate assembly is inserted into the slot 7, the rear end of the spring 12 presses against the spring step 8. Under the action of the spring 12, the movable lock plate 10 extends from the front end of the handle body 5 and is located below the fixed lock plate 9, thereby forming a sandwich 17 between the fixed lock plate 9 and the movable lock plate 10.

[0041] After the lock plate assembly is inserted into the slot 7, the upper part of the slide button 11 is exposed outside the handle body 5. In one embodiment, the front end of the slide button 11 has an upwardly turned up portion 18, and after the lock plate assembly is inserted into the slot 7, the turned up portion 18 is located above the handle body 8, and the slide button 11 can be slid by operating the turned up portion 18 to drive the lock plate 10 to move.

[0042] After the lock plate assembly is inserted into the slot 7, the fastener 6 is inserted into the handle 5 and the rear of the fixed lock plate 9 is positioned. The method of positioning the fixed lock plate 9 by the fastener 6 is as follows: The rear part of the fixed lock plate 9 is provided with a positioning opening 19, and a positioning block 20 extending into the positioning opening 19 is provided in the positioning opening 19; the fastener 6 includes a fastening block 21, and an elastic fastening arm 22 extending upward is provided on the fastening block 21, and a fastening hook 23 is provided on the elastic fastening arm 22, and the fastening hook 23 can be hooked on the positioning block 20 after penetrating upward into the positioning opening 19, that is, the elastic fastening arm 22 is deformed in the process of passing over the positioning block 20 when penetrating upward into the positioning opening 19, until the elastic fastening arm 22 returns to its original position after passing over the positioning block 20, at which time the fastening hook 23 can be hooked on the positioning block 20. In order to enable the fastening hook 23 to pass over the positioning block smoothly, the surface of the fastening hook 23 facing the positioning block 20 is an inclined surface facing the positioning block 20.

[0043] The fastening block 21 is also provided with a limit block 24 extending upward, and the rear side surface of the limit block 24 has a vertical limit surface 25. The rear side surface of the positioning opening 19 is a vertical rear side surface 26 corresponding to the vertical limit surface 25. After the limit block 24 is inserted upward into the positioning opening 19, the vertical limit surface 25 and the vertical rear side surface 26 are abutted against each other, so that the fixed lock plate 9 is limited in the forward direction.

[0044] In one embodiment, the elastic fastening arms 22 have two parallel arms to achieve better positioning, and the limit blocks 24 have two parallel arms to achieve better positioning. The two limit blocks 24 are respectively located on the outside of the two elastic fastening arms.

[0045] When disassembling the detachable cookware handle, the disassembly rod 29 is used to disassemble the detachable cookware handle: The fastening block 21 is provided with a disassembly hole 30 which passes through from top to bottom. The head of the disassembly rod 29 is a disassembly head 31. The disassembly rod 29 is also provided with a disassembly step 32. When disassembling the detachable cookware handle, the disassembly rod 29 is inserted into the disassembly hole 30 and the disassembly head 31 reaches the position of the elastic fastening arm 22. When there are two elastic fastening arms 22, the disassembly head 31 reaches between the two elastic fastening arms 22. At this time, the disassembly head 31 is parallel to the elastic fastening arm 22 and the disassembly step 32 is located above the upper end surface of the fastening block 21. After rotating the disassembly rod 29, the disassembly head 31 is perpendicular to the elastic fastening arm 22. During the rotation process, the disassembly head 31 pushes the elastic fastening arm 22 outward so that the fastening hook 23 is separated from the positioning block 20. Then the disassembly rod 29 is pulled outward, and the disassembly step 32 abuts against the fastening block 21 to pull it outward, thereby disassembling the fastener 6, and the locking plate assembly can be withdrawn from the slot.

[0046] In order to enable the disassembly head 31 of the disassembly rod 29 to push the elastic fastening arm 22 outward during the rotation process, the thickness of the disassembly head 31 is less than the distance between the two elastic fastening arms 22, and the width of the disassembly head 31 is greater than the distance between the two elastic fastening arms 22. In order to further ensure that the disassembly head 31 of the disassembly rod 29 can push the elastic fastening arm 22 outward during the rotation process, the inner side of the elastic fastening arm 22 has a protrusion 33 corresponding to the inserted disassembly head 31, and the disassembly head 31 is easy to push against the protrusion 33 during the rotation, thereby pushing the elastic fastening arm 22 outward.

[0047] In one embodiment, the upper portion of the disassembly hole 30 is a flat hole, and the flat hole is parallel to the elastic fastening arm 22; the disassembly head 31 is a flat disassembly head, and the lower end of the disassembly head 31 forms the disassembly step 32. The upper portion of the disassembly hole 30 is a flat hole, and the disassembly head 31 is a flat disassembly head. When the disassembly rod 29 penetrates the disassembly hole 30, the flat disassembly head 31 can smoothly pass through the upper portion of the flat disassembly 30, and after the disassembly rod 29 rotates, the disassembly step 32 at the lower end of the disassembly head 31 exceeds the upper portion of the disassembly hole 30, so that it can abut against the fastening block 21. At this time, the fastening block 21 can be pulled outward by pulling the disassembly rod 29 outward.

[0048] When the detachable cookware handle is installed on the cookware, the cookware comprises a cookware body 1, a cookware ear 2 is provided on the outer surface of the side of the cookware body 1, a through hole 3 is opened on the cookware ear 2, and a detachable cookware handle 4 is detachably connected to the cookware ear 2: first, the lower folding plate 15 and the abutting plate 16 of the fixed locking plate are inserted into the through hole 3, and then the movable locking plate 10 is moved back and presses down the detachable cookware handle until the abutting plate 16 of the fixed locking plate abuts against the back of the cookware ear 2, and then the movable locking plate 10 is reset under the action of the spring 12, and at this time, the movable locking plate 10 abuts against the back of the cookware ear 2, and the cookware ear 2 is sandwiched in the interlayer 17. In one embodiment, the front end of the handle body 5 is provided with a top block 27 protruding forward, and after the detachable cookware handle 4 is installed, the cookware ear 2 abuts against the top block 27, so that the cookware ear 27 and the detachable cookware handle 4 are more stable after completion. When the detachable cookware handle 4 is installed, the movable locking plate 10 is moved backward by directly operating the sliding button 11 to overcome the elastic force of the spring 12 to slide the sliding button 11 backward, thereby driving the movable locking plate 10 to move backward; or the pot ear pushes the movable locking plate 10 backward during the pressing process of the detachable cookware handle 4. At this time, in order to enable the pot ear to smoothly push the movable locking plate 10 backward during the pressing process, an inclined surface 28 extending downward from the front to the rear may be provided on the lower side of the movable locking plate 10. When the detachable cookware handle 4 is pressed downward, the inclined surface 28 first abuts against the pot ear 2, and the movable locking plate 10 can be automatically pushed backward under the action of the inclined surface 28.

[0049] When the detachable cookware handle 4 is removed from the cookware, the slide button 11 is operated to overcome the elastic force of the spring 12 to slide the slide button 11 backward, thereby driving the movable locking plate 10 to retreat backward, so that the movable locking plate 10 is retracted into the handle body 5. At this time, there is no interlayer any more, and the detachable cookware handle 4 can be smoothly removed.
