Description

Technical Field

[0001] This utility model belongs to the field of cookware technology and relates to a detachable handle. Background Technology

[0002] Cookware is an essential kitchen utensil. However, currently, the pot body and handle are connected in the following ways: 1. The pot body and handle are welded into a single structure, which has the following problems: the connection between the pot body and handle is difficult to clean; multiple pots are difficult to store; if the pot body or handle is damaged, all pots need to be replaced, wasting resources; 2. The pot body and handle are fixed with bolts, which has the following problems: the connection between the pot body and handle is difficult to clean, the connecting bolts are prone to rust, bolt holes are required, the manufacturing process is complicated, and the bolts are prone to loosening, causing the pot body and handle to separate; 3. The handle is clamped to the pot body, which requires turning the handle knob during operation, requiring both hands, which is inconvenient. In addition, the knob protrudes from the handle body, making it easy to accidentally touch and cause the handle to separate. Therefore, all existing methods of connecting the pot body and handle have problems that need to be solved.

[0003] To address this, a detachable pot handle was designed and a Chinese patent was applied for, with application number 202321607026.3 and publication number CN220608176U. The detachable pot handle includes a main body, a clamping plate that moves along the length of the main body for clamping and detaching the outer edge of the pot, and a cover plate rotatably connected to the end of the main body. The clamping plate has an arc-shaped component that abuts against the cover plate on its side. A tension spring is provided between the bottom end of the main body and the clamping plate, which applies a force to the clamping plate in a direction away from the length of the main body. When the cover plate rotates downwards, it moves away from the arc-shaped component, and the tension spring drives the clamping plate to move away from the length of the main body. When the cover plate rotates upwards, it moves closer to the arc-shaped component, which drives the clamping plate to move closer to the length of the main body.

[0004] However, the aforementioned detachable pot handle uses the engagement of the first and second teeth to achieve relative positioning between the main handle and the secondary handle during use. To facilitate disassembly after engagement, the unevenness of the first and second teeth is relatively low. Thus, during repeated disassembly and assembly, the first and second teeth of the detachable pot handle are prone to wear, causing the positioning to loosen and affecting the stability of the detachable handle when holding the pot. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a detachable handle, which solves the problem that wear and tear on the detachable handle during use affects the stability of holding the cookware.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A detachable handle includes a main handle in the shape of a long strip, a long, plate-shaped clamping piece inserted inside the main handle, a secondary handle in the shape of a long strip, and an unlocking spring. The front end of the clamping piece extends from the front end of the main handle and bends downward to form a clamping part. A clamping opening is formed between the clamping part and the front end of the main handle. The clamping piece can move forward under the elastic force of the unlocking spring. The front end of the secondary handle is hinged inside the main handle. The top of the rear end of the secondary handle has a protruding blocking part that prevents the clamping piece from moving forward. A push button is inserted through the top of the main handle and can slide back and forth relative to the main handle. The secondary handle is characterized by having a plate-shaped locking plate fixed to the top. The bottom of the push button has two vertically arranged, plate-shaped locking members. The front side of the bottom of each of the two locking members has a protruding hook that abuts against the lower side of the locking plate. The length of the hook in the front-back direction is less than the forward movement stroke of the push button but greater than half of the forward movement stroke of the push button.

[0008] When the detachable handle is in the pot-gripping position, the secondary handle swings upward around the hinge point. Two hooks at the bottom of the two locking parts engage with the underside of the locking plate, achieving relative positioning between the main handle and the secondary handle; that is, the secondary handle cannot swing downward relative to the main handle. At this time, the blocking part at the top of the secondary handle prevents the clamping plate from moving forward under the force of the unlocking spring, keeping the clamping opening in a smaller position to stably hold the pot.

[0009] When the handle needs to be removed, manually push the top push button backward, causing the two locking parts fixed at the bottom of the push button to move backward, so that the two hooks move away from the locking plate. After the hooks leave the locking plate, the vertical restriction on the locking plate is released, allowing the secondary handle to swing downward. The blocking part at the top of the rear end of the secondary handle also swings downward. After the blocking part is removed, the clamping plate moves forward under the elastic force of the unlocking spring, increasing the clamping opening, and the handle can then be removed.

[0010] In this detachable handle, two hooks at the bottom of two vertically arranged, plate-shaped locking elements hook onto the underside of a plate-shaped locking plate. In actual installation, the horizontal length of the hooks can be only slightly less than the forward travel of the push button. This ensures the locking elements' stability in limiting the locking plate while allowing the push button to disengage the hooks and release the lock, thereby guaranteeing the relative positioning stability between the secondary handle and the main handle, and achieving stable clamping of the cookware. Furthermore, using the two hooks on the two locking elements to limit the locking plate also prevents the locking plate and secondary handle from deviating or swaying after being limited, further ensuring positioning stability.

[0011] In the aforementioned detachable handle, the top of the secondary handle is fixed with an upwardly protruding mounting base. The locking plate is fixed to the top of the mounting base by fasteners, and a locking opening is formed between the lower side of the locking plate and the top of the secondary handle for the hook to extend into. By raising the locking plate with the mounting base, a locking opening is left below the locking plate to facilitate the insertion of the hook and ensure positioning stability.

[0012] In the aforementioned detachable handle, the two locking members are located on both sides of the clamping plate, and both locking members are adjacent to the clamping plate. The location of the two locking members on both sides of the clamping plate increases the distance between them, ensuring stability when their hooks abut against the lower side of the locking plate. Simultaneously, the adjacent arrangement of the two locking members to the clamping plate, meaning a smaller gap between them, facilitates the clamping plate's guidance of the back-and-forth movement of the two locking members, ensuring the stability of their movement and, consequently, the stability of the positioning between the locking members and the locking plate.

[0013] In the aforementioned detachable handle, a return spring is provided between the push button and the main handle to allow the push button to move forward. The lower side of the hook has a guide surface that is inclined relative to the locking plate. The return spring acts on the push button, causing the push button to always have a tendency to move forward. Consequently, the locking member and the hook on the locking member both have a tendency to move forward to limit the locking plate. The guide surface is provided to facilitate the locking plate pushing the locking member backward when it moves upward, eliminating the need for the user to operate the push button while simultaneously moving the secondary handle upward, thus simplifying the user's operation.

[0014] In the aforementioned detachable handle, the blocking part is block-shaped, and its rear side is an inclined surface set at an angle relative to the horizontal plane. The upper part of the inclined surface is positioned further forward than the lower part. The rear end of the clamping piece has a downwardly bent abutment that can rest against the inclined surface. The blocking part and the abutment work together to prevent the clamping piece from moving forward, while the inclined surface allows the clamping piece to be pushed backward when the secondary handle is swung, making operation convenient.

[0015] Compared with the prior art, in this detachable handle, two hooks at the bottom of two vertically arranged, plate-shaped locking members hook onto the lower side of a plate-shaped locking plate. The horizontal length of the hooks can be only slightly less than the stroke of the push button. In this way, the locking members' limiting stability on the locking plate is ensured while the hooks can be pushed off the locking plate by the push button to release the lock. This, in turn, ensures the relative positioning stability between the secondary handle and the main handle, thereby achieving stable clamping of the cookware. Attached Figure Description

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 As shown, the detachable handle includes a main handle 1 that is elongated and arranged in the front-to-back direction, a clamping plate 2 that is elongated and arranged in the front-to-back direction and inserted inside the main handle 1, a secondary handle 3 that is elongated, and an unlocking spring 4.

[0020] The front end of the clamping piece 2 extends from the front end of the main handle 1, and the front end of the clamping piece 2 bends downward to form a clamping part 2a. A clamping opening 5 is formed between the clamping part 2a and the front end of the main handle 1. The bottom of the main handle 1 has a recessed cavity. The front end of the auxiliary handle 3 is hinged to the main handle 1 through a horizontally set hinge shaft, and the auxiliary handle 3 can swing around the hinge shaft to retract into the recessed cavity. An unlocking spring 4 is also provided in the main body. The unlocking spring 4 is a tension spring, one end of which is sleeved on the outside of the hinge shaft, and the other end is connected to the bottom of the clamping piece 2. The clamping piece 2 can move forward under the elastic force of the unlocking spring 4.

[0021] The top of the rear end of the auxiliary handle 3 has a protruding blocking part 3a that prevents the clamping piece 2 from moving forward. The blocking part 3a is block-shaped, and the rear side of the blocking part 3a is an inclined surface 3b that is inclined relative to the horizontal plane. The upper part of the inclined surface 3b is further forward than the lower part of the inclined surface 3b. The rear end of the clamping piece 2 has a downwardly bent abutting part 2b. The abutting part 2b is also inclined relative to the horizontal plane, and the inclination angle of the abutting part 2b is approximately the same as the inclination angle of the inclined surface 3b. The abutting part 2b can abut against the inclined surface 3b.

[0022] A push button 6 is inserted through the top of the main handle 1, and the push button 6 can slide back and forth relative to the main handle 1. A return spring 11 is provided between the push button 6 and the main handle 1 to move the push button 6 forward. A plate-shaped locking plate 7 is fixed to the top of the auxiliary handle 3, and two vertically arranged plate-shaped locking members 8 are fixed to the bottom of the push button 6. The front side of the bottom of the two locking members 8 has a protruding hook 8a that can abut against the lower side of the locking plate 7. In this embodiment, the length of the hook 8a in the front-back direction is less than the maximum forward stroke of the push button 6 but greater than half of the maximum forward stroke of the push button 6.

[0023] In this embodiment, the top of the middle section of the secondary handle 3 has a slot, and a mounting base 9 is fixedly engaged in the slot. The top of the mounting base 9 extends upward out of the slot. The locking plate 7 is fixed to the top of the mounting base 9 by screws passing through the locking plate 7. The outer edge of the locking plate 7 extends out of the side of the mounting base 9, so that a locking opening 10 for the hook 8a to extend into is formed between the lower side of the locking plate 7 and the top of the secondary handle 3. The tops of the two locking members 8 are simultaneously fixed to a plate-shaped fixing part, which is fixed to the push button 6 by screws. The two locking members 8 are located on both sides of the clamping plate 2 and are adjacent to the clamping plate 2. The lower side of the hook 8a has a guide surface 8b that is inclined relative to the locking plate 7.

[0024] When the detachable handle is in the pot-clamping position, the secondary handle 3 swings upward around the hinge point. The locking plate 7 abuts against the guide surface 8b of the hook 8a, pushing the hook 8a, locking member 8, and push button 6 to move backward against the spring force of the return spring 11 until the locking plate 7 exceeds the top surface of the hook 8a. Under the spring force of the return spring 11, the push button 6 drives the locking member 8 and hook 8a forward. The two hooks 8a at the bottom of the two locking members 8 hook onto the lower side of the locking plate 7, preventing the secondary handle 3 from swinging downward and achieving relative positioning between the main handle 1 and the secondary handle 3. At the same time, the blocking part 3a at the top of the secondary handle 3, relying on the cooperation of the inclined surface 3b and the abutment part 2b, pushes the clamping piece 2 to move backward against the spring force of the unlocking spring 4 and abuts against the abutment part 2b, preventing the clamping piece 2 from moving forward. Thus, the clamping opening 5 is in a smaller state to stably clamp the pot.

[0025] When the handle needs to be removed, manually push the top push button 6 backward, causing the two locking pieces 8 fixed to the bottom of the push button 6 to move backward, so that the two hooks 8a move backward away from the locking plate 7, releasing the vertical restriction on the locking plate 7. The clamping piece 2 moves forward under the elastic force of the unlocking spring 4, and applies force to the blocking part 3a of the secondary handle 3 through the abutment part 2b, causing the rear end of the secondary handle 3 to swing downward around the hinge axis. After the clamping piece 2 moves forward, the clamping opening 5 opens, and the handle can be removed.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
