Description

Technical Field

[0001] This invention belongs to the field of cookware technology, specifically relating to a detachable universal pot handle and cookware. Background Technology

[0002] Cookware is a common cooking utensil used for various cooking methods such as boiling, frying, and stir-frying. A typical cookware set may include a complete set of utensils, such as a frying pan, milk pan, or saucepan. Most pot handles are fixedly welded or riveted to the pot body for easy handling and to prevent burns. Because cookware takes up considerable space when stored, cookware with detachable handles has emerged to facilitate storage and portability, allowing a set of cookware of different sizes to be equipped with only one handle. Existing detachable universal handles usually have buttons for controlling the assembly and disassembly of the handle and pot body, allowing for easy removal and replacement. However, existing universal handles lack safety locking devices, which could lead to accidental button presses during use, causing the cookware to fall and resulting in an accident. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a detachable universal pot handle and cookware with a safety locking device.

[0004] The present invention provides a detachable universal pot handle with a safety locking device, comprising:

[0005] The handle, including the upper cover and the lower cover, together form a hollow cavity;

[0006] The clamping piece includes a clamping arm and a clamping head. The clamping arm is disposed in the cavity, and the clamping head is located at the front end of the clamping arm. It is bent and formed to cooperate with the front end of the handle to form a pot clamping part. A roller is provided on the upper surface of the middle part of the clamping arm, and a strip hole is provided at the rear part of the clamping arm. The front diameter of the strip hole is larger than the rear diameter. A spring is provided at the rear end of the clamping arm, and the spring is installed in the spring groove of the lower cover.

[0007] A pressure rod is hinged to the upper cover and can protrude from the upper cover. The pressure rod is provided with an arc-shaped protrusion that contacts the roller.

[0008] The button has a three-stage stepped shaft structure. The diameter of the lower shaft is smaller than the front diameter of the strip hole, the diameter of the upper shaft is larger than both the front and rear diameters of the strip hole, and the diameter of the middle shaft is smaller than the rear diameter of the strip hole. The button is installed in the mounting hole of the lower cover, passes through the strip hole, and protrudes from the upper cover. A return spring is provided in the mounting hole.

[0009] The safety locking device includes a limit key, which is installed in the mounting groove of the upper cover and has a top protrusion extending out of the upper cover. A pressure spring is provided in the mounting groove, and the pressure spring presses the limit key into the limit hole of the pressure rod.

[0010] According to some embodiments of the present invention, the limiting hole is located at the rear end of the pressure rod.

[0011] According to some embodiments of the present invention, the front end of the limiting key is provided with a pin, which can be inserted into the limiting hole.

[0012] According to some embodiments of the present invention, a protrusion for fixing the spring is provided at the rear end of the clamping arm.

[0036] Reference Figure 1 , Figure 2 , Figure 3 A detachable universal pot handle with a safety locking device, comprising:

[0037] The handle 1 includes an upper cover 11 and a lower cover 12, which together form an internally hollow cavity; the upper cover 11 and the lower cover 12 are connected by screws.

[0038] Reference Figure 7 The clamping piece 2 includes a clamping arm 21 and a clamping head 22. The clamping arm 21 is disposed within the cavity, and the clamping head 22 is located at the front end of the clamping arm 21, bent into shape, and cooperates with the front end of the handle 1 to form a cookware clamping part. A roller 23 is provided on the upper surface of the middle part of the clamping arm 21, and a strip-shaped hole 24 is provided at the rear part of the clamping arm 21. The front diameter of the strip-shaped hole 24 is larger than the rear diameter. A spring 3 is provided at the rear end of the clamping arm 21, and the spring 3 is installed in the spring groove 121 of the lower cover 12. To facilitate the installation and fixation of the spring 3, a protruding pin 25 for fixing the spring 3 is provided at the rear end of the clamping arm 21. An elliptical hole 26 is provided at the front part of the clamping arm 21, and the screw passes through the elliptical hole 26, thereby effectively controlling the movement distance of the clamping piece 2.

[0039] To make the handle more securely mounted on the pot body, the clamp 22 is integrally injection molded with an anti-slip rubber sleeve 221, and the surface of the anti-slip rubber sleeve 221 is provided with transverse teeth.

[0040] Reference Figure 8 The pressure rod 4 is hinged inside the upper cover 11 and can protrude from the upper cover 12. The pressure rod 4 is provided with an arc-shaped protrusion 41 that contacts the roller 23.

[0041] Reference Figure 9The button 5 has a three-stage stepped shaft structure. The diameter of the lower shaft 51 is smaller than the front diameter of the strip hole 24 but larger than the rear diameter of the strip hole 24. The diameter of the upper shaft 52 is larger than the front diameter of the strip hole 24. The diameter of the middle shaft 53 is smaller than the rear diameter of the strip hole 24. The button 5 is installed in the mounting hole 122 of the lower cover 12, passes through the strip hole 24 and protrudes from the upper cover 12. A return spring 6 is provided in the mounting hole 122. Under the action of the return spring 6, the button 5 returns to its natural state. At this time, the lower shaft 51 is located at the front end diameter of the strip hole 24. Since the lower shaft 51 is larger than the rear end diameter of the strip hole 24, the clamping piece 2 cannot move. Only when the button 5 is pressed down, since the shaft diameter of the upper shaft 52 is larger than the front end diameter of the strip hole 24, the middle shaft 53 can only be located at the front end diameter of the strip hole 24. At this time, the clamping piece 2 moves forward relative to the handle 1 under the action of the spring 3, so that the middle shaft 53 is located at the rear end diameter of the strip hole 24.

[0042] Reference Figure 4 , Figure 5 The safety locking device 7 includes a limit key 71, which is installed in the mounting groove 111 of the upper cover 11. A top protrusion 713 extends out of the upper cover 12. A pressure spring 72 is installed in the mounting groove 111, pressing the limit key 71 into the limit hole 42 of the pressure rod 4. The limit hole 42 is located at the rear end of the pressure rod 4. A pin 711 is provided at the front end of the limit key 71, which can be inserted into the limit hole 42. The limit key 71 has a positioning groove 712 for mounting the pressure spring 72. In its natural state, the safety locking device 7 locks the pressure rod 4, preventing the button 5 from being pressed and preventing accidental unlocking of the handle by the user.

[0043] Reference Figure 10 This invention features a safety locking device 7. The unlocking button 5 can only be pressed after the safety locking device 7 is opened, causing the clamping piece 2 to move forward relative to the handle 1 under the action of the spring 3, thus opening the handle. At this time, the pressure rod 4 opens outward around the hinge point under the drive of the roller 23 in the middle of the clamping arm 21. When it is necessary to clamp the handle, simply press the pressure rod 4. Driven by the pressure rod 4, the clamping piece 2 moves backward relative to the handle. Simultaneously, the safety locking device 7 locks the pressure rod 4, completing the installation of the handle onto the pot body. Because this invention employs a dual-switch design, it effectively prevents accidental unlocking of the handle by the user, ensuring the safety of handle use.

[0044] Another embodiment of the present invention provides a cookware including a detachable universal handle with a safety locking device as described above. The advantages of the cookware of the present invention over the prior art are the same as those of the aforementioned universal handle, and will not be repeated here.
