Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen utensils, and particularly relates to a detachable pot handle with high safety. Background Technique

[0002] With the development of society, kitchen utensils are becoming more and more practical and convenient. As an essential utensil in the kitchen, the pot plays a major role in cooking. There are various types of pots, and some of them have detachable handles. These pots can disassemble and assemble the handle when necessary to prevent the handle from causing obstruction during cooking and to make one handle fit multiple pots. This detachable handle has been popular in the market and is loved by consumers, but there are also many potential safety hazards. The most serious one is that the handle accidentally disengages, causing the pot to tip over. One type of handle disengages when the unlocking button is pressed, which is one of the least safe handles. Additionally, there is another type of handle with an anti-disengagement function. In general, when the user holds the handle, the locking handle is pinched, so even if the unlocking button is accidentally touched, the handle will not disengage. This is also one of the most common anti-disengagement structures. However, in special cases, such as when the pot is heavy, the pot may overcome the grip force applied by the user on the locking handle and forcefully disengage, still posing a safety hazard. At present, although the development of handles tends to simplify the structure, almost all use the above method of holding the locking handle to ensure that the locking handle will not disengage during use, but safety problems caused by handle disengagement still emerge in an endless stream. Therefore, the industry urgently needs a detachable pot handle with higher safety.

[0003] In the prior art, such as the "detachable pot handle" disclosed in the Chinese invention patent authorization publication number CN107625461B, includes: a handle, with a jaw seat below one end of the handle. There is a step on the jaw seat, and a jaw groove is provided between the jaw seat and the handle. There is a cavity and a relief cavity below the middle part, and the cavity and the relief cavity are connected through a lock core hole; a hand pressure handle, installed on the handle, with one end extending out through the jaw groove and the other end having a lock catch mounting seat. There is a lock core relief cavity on the hand pressure handle; an opening and closing button, arranged in the cavity and installed on the handle, with a button thereon; a lock core, with one end installed at the lower end of the opening and closing button and the other end passing through the lock core hole; a lock catch, installed on the side surface of the lock catch mounting seat facing the lock core hole, with a lock hole thereon, and the lock hole cooperates with the lock core; a jaw plate, with one end fixed to the hand pressure handle and the other end folded down to form a jaw, and the jaw corresponds to the jaw seat. Among them, the hand pressure handle plays the role of anti-disengagement, but there are still safety problems in the above special cases.

[0004] In view of the above situation, it is necessary to design a detachable pot handle with a simple structure, few components, which can lock the unlocking button and can only be unlocked when the safety button and the unlocking button are opened simultaneously, and has high safety.

A reset spring shaft 52 is arranged at one end of the aforesaid unlocking button 5 facing the safety button 6. An unlocking button return spring 521 is connected between the reset spring shaft 52 and the lock plate hinge shaft 32. A lock handle cavity Ⅱ23 is formed upward in the middle of the aforesaid lock handle 2. The unlocking button 5 and the lock rod 7 are located in the lock handle cavity Ⅱ23 in the locked state.

[0030] In this embodiment, at one end of the aforementioned lock handle 2 facing the lock block 8, there is formed a mounting plate 22 for the lock block connecting member. A lock block connecting member 24 is fixed to the mounting plate 22 of the lock block connecting member by screws. On the side of the lock block connecting member 24 facing the lock block 8, there is formed a rack 241 of the lock block connecting member. On the lock block 8, there is formed a lock block rack 82 that cooperates with the rack 241 of the lock block connecting member. A lock block shaft 81 also passes through the middle of the lock block 8. At the installation position of the lock block shaft 81 corresponding to the grip 1, a lock block shaft hole 121 is provided. The lock block 8 is placed in the lock block cavity 12 and is hinged to the lock block shaft hole 121 through the lock block shaft 81. At the end of the grip 1 near the lock block 8, a hanging hole seat 9 is fixed. On the side of the hanging hole seat 9 facing the lock block 8, there is formed a reset spring seat 91. A lock block reset spring 92 is arranged in the reset spring seat 91. At the position of the lock block reset spring 92 on the lock block 8, there is formed a spring fixing column 83 connected to the lock block reset spring 92.

[0031] On the aforementioned unlocking button 5, there is provided an unlocking button shaft 51. At the installation positions of the grip 1 corresponding to the unlocking button shaft 51, unlocking button shaft holes 111 are respectively provided. The unlocking button 5 can rotate around the unlocking button shaft 51. At the position of the unlocking button 5 above the unlocking button shaft 51, there is formed a lock rod shaft 53. One end of the lock rod 7 is hinged to the lock rod shaft 53.

[0032] In this embodiment, a sheath 10 is installed below one end of the grip 1 facing the clamping plate 4. On both sides of the sheath 10, there are respectively formed a sheath clamping foot 101. The sheath 10 is semi-surroundingly arranged on the grip 1; on both side surfaces of the grip 1, there are respectively provided a sheath clamping groove 16 for clamping the sheath clamping foot 101. The sheath 10 is a metal part, and the metal part is preferably stainless steel.

[0033] Please continue to refer to Figure 1 and in combination with Figures 3 to 6 , describe the working principle of the present invention: As shown in Figure 3 , when the handle is in the locked state, the aforementioned grip 1 and the lock handle 2 are closed. The clamping plate 4 and the clamping surface 15 cooperate with each other to clamp the pot body. At this time, the lock block connecting member 24 and the lock block 8 are locked by the mutual engagement of the rack 241 of the lock block connecting member and the lock block rack 82. The unlocking button 5 rotates counterclockwise around the unlocking button shaft 51 until the lock groove 54 is stuck into the lock tooth 612. When the unlocking button 5 is accidentally touched, since the unlocking button 5 is locked by the safety button 6 and cannot rotate, and when the safety button 6 is accidentally touched, it can only contact and lock with the unlocking button 5 and will not cause the unlocking button 5 to push the lock rod 7 to unlock; when the handle needs to be unlocked, as shown in Figure 4As shown, the safety button 6 is first pushed to slide, and the safety button 6 slides to disengage the lock tooth 612 from the lock groove 54. The unlocking button 5 rotates clockwise around the unlocking button shaft 51 under the pulling force of the unlocking button return spring 521 to disengage the lock tooth 612. Figure 5 As shown, the unlocking button 5 is pressed to make the unlocking button 5 continue to rotate clockwise around the unlocking button shaft 51. During the rotation process, the unlocking button 5 pushes the locking rod 7 to lean against the locking block 8. Under the action of the locking rod 7, the locking block 8 overcomes the elastic force of the locking block return spring 92 and rotates clockwise around the locking block shaft 81. The locking block rack 82 is disengaged from the locking block connecting piece rack 241 and the lock handle 2 is unlocked. Finally, as shown in FIG. Figure 6 As shown, the lock handle 2 is turned over to rotate clockwise around the lock plate hinge axis 32, and the clamping plate 4 and the clamping surface 15 are separated to release the clamping state.
