Description

Technical Field

[0001] The utility model belongs to the technical field of cookers and relates to a gear-propelled unlocking and detachable handle. Background Art

[0002] A pot is a cooking utensil that can be used for cooking, boiling, frying, deep-frying, stir-frying and other cooking operations. A pot basically includes a pot body, a pot lid and a handle. Traditional handles are riveted to the outside of the pot body by rivets (or screws), so that there will be rivet heads on the side of the pot body. In this way, oil stains will accumulate on the rivet heads during cooking, which will easily rust over time and are inconvenient to clean. In addition, if rivets (or screws) are used for connection, holes need to be punched on the pot body and the pot handle, which is very inconvenient to process and is prone to slipping and loosening after assembly.

[0003] In addition, there are also some methods that use spot welding to directly fix the handle on the pot body. Although the connection is firm, the handle cannot be removed, which makes the pot body bulky and is not conducive to packaging and transportation.

[0004] For this reason, detachable handles are currently a major trend in the selection of cookware. Utility Model Content

[0005] The utility model aims to solve the above problems existing in the prior art and proposes a detachable handle which is unlocked by a gear, thereby solving the problem that the existing pot body with a fixed handle is large in size.

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

[0007] The gear-propelled unlocking detachable handle comprises a handle body, a secondary handle and a locking tongue inserted in the handle body, the front end of the locking tongue passing through the front end of the handle body and the front end of the locking tongue having a bent clamping portion, a clamping opening being formed between the clamping portion and the front end of the handle body, the bottom of the handle body having a notch concave upwardly, the front end of the secondary handle being hinged on the handle body and being able to swing around a hinge point and retract into the notch, and its characteristic is that the locking tongue is fixedly connected to the secondary handle and when the secondary handle swings out of the notch, the clamping portion is away from the front end of the handle body around the hinge point between the secondary handle and the handle body, a rack is also horizontally inserted in the handle body, the top of the handle body is rotatably connected to a button, the bottom of the button has teeth meshing with the rack, and when the button rotates relative to the handle body, it can push the rack to move backward and cause the rear end of the rack to position the secondary handle.

[0008] In this gear - driven unlocking detachable handle, the end for clamping the cookware is the front end. When it is necessary to clamp the cookware, rotate the button circumferentially. The button pushes the rack forward through the teeth, releasing the positioning of the rear end of the rack on the position of the secondary handle. The secondary handle can swing downward around the hinge point to expose the notch. At the same time, the locking tongue fixedly connected to the secondary handle rotates synchronously with the secondary handle around the hinge point. The clamping part at the front end of the handle body swings upward while the secondary handle swings downward. The front end face of the clamping part away from the handle body makes the clamping opening open. After clamping the edge of the cookware into the clamping opening, swing the secondary handle upward so that it retracts into the notch and is opposite to the position of the rear end of the rack. At the same time, the clamping part swings downward, the clamping opening shrinks and clamps the edge of the cookware. Then, moving the rack backward to lock the position of the secondary handle can keep the handle clamping the cookware firmly. During the use of this gear - driven unlocking detachable handle, the disassembly and clamping of the cookware can be realized according to the rotational operations of the button and the secondary handle. It is convenient to use, and the handle can be removed during packaging or transportation, reducing the volume of the cookware. In addition, the whole handle only includes three movable parts: the secondary handle, the rack and the button. And the button and the rack are engaged with each other by teeth, with simple and stable cooperation, not prone to failure and high reliability.

[0009] In the above - mentioned gear - driven unlocking detachable handle, the handle body includes a main body with a notch at the bottom and a guide seat fixed in the notch of the main body. A guide hole is formed in the guide seat along the front - rear direction. The rack is horizontally inserted into the guide hole and the rear end of the rack passes through the guide seat. A through - hole is formed through the top of the guide seat. The button is rotatably fixed at the through - hole of the guide seat and the bottom of the button passes through the through - hole and meshes with the rack. The guide seat limits or positions the mutually cooperating rack and button at the same time, making the cooperation between the button and the rack more stable. And through the guiding of the guide hole for the movement of the rack, it further ensures the stability of the cooperation between the rack and the secondary handle.

[0010] In the above - mentioned gear - driven unlocking detachable handle, a locking spring is arranged between the front end of the rack and the guide seat. The top of the secondary handle has a limiting part protruding towards the rack. The rack can move backward under the elastic force of the locking spring and abut against the lower side of the limiting part. Relying on the locking spring to realize the automatic backward movement of the rack, ensuring that when the secondary handle swings upward and retracts into the notch, the rack abuts against the lower side of the limiting part to automatically lock the position of the secondary handle, avoiding the secondary handle driving the limiting part to swing downward automatically.

[0011] In the above - mentioned gear - driven unlocking detachable handle, the front end face of the rack has a concave hole recessed backward. The rear end of the locking spring extends into the concave hole and abuts against the bottom surface of the concave hole. The concave hole is used to limit the rear - end position of the locking spring, ensuring that the elastic force of the locking spring drives the rack to move back and forth.

[0012] In the above-mentioned gear-pushing unlocking detachable handle, the top of the button has an operating part that protrudes upward from the top of the handle body. The operating part protrudes from the top of the handle body to facilitate the operation and use by the user.

[0013] In the above-mentioned gear-pushing unlocking detachable handle, an unlocking spring is further arranged in the handle body. Two ends of the unlocking spring respectively abut against the handle body and the sub-handle, and the sub-handle can swing downward around the hinge point under the elastic force of the unlocking spring. The arrangement of the unlocking spring enables the sub-handle to automatically swing downward after the user operates the button, facilitating the operation.

[0014] Compared with the prior art, the present gear-pushing unlocking detachable handle has the following advantages:

[0015] 1. By operating the button and the sub-handle, the present gear-pushing unlocking detachable handle makes the clamping opening for clamping the edge of the cookware expand or contract, so as to achieve disassembly and fixation, enabling the handle of the cookware to be removed during packaging or transportation, and reducing the volume of the cookware.

[0016] 2. During the use of the present gear-pushing unlocking detachable handle, only the rotational operations of the button and the sub-handle are required to achieve the disassembly and clamping of the cookware, which is convenient to use.

[0017] 3. The present gear-pushing unlocking detachable handle only includes three movable parts, namely the sub-handle, the rack and the button, and the button and the rack are engaged with each other by tooth meshing. The cooperation is simple and stable, not prone to failure, and has high reliability. Description of the Drawings

[0020] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0021] In this embodiment, the end of the handle for clamping the cookware is taken as the front end.

[0022] Such as Figure 1As shown in the figure, the gear-driven unlocking detachable handle includes a handle body 1 that is strip-shaped and horizontally arranged, a sub-handle 2 that is strip-shaped, and a lock tongue 3 that is sheet-shaped and horizontally penetrates through the handle body 1. The front end of the lock tongue 3 penetrates through the front end of the handle body 1 and bends downward to form a clamping portion 31. A clamping opening 4 is formed between the clamping portion 31 and the front end of the handle body 1. The bottom of the handle body 1 has a recessed notch 11a that is recessed upward. The front end of the sub-handle 2 is hinged inside the front end of the handle body 1 and can swing around the hinge point and retract into the notch 11a.

[0023] Among them, the part of the lock tongue 3 located inside the handle body 1 is fixed to the sub-handle 2 through a fastener. Since the hinge point is between the clamping portion 31 and the rear end of the sub-handle 2, when the sub-handle 2 swings out of the notch 11a around the hinge point, the clamping portion 31 swings upward around the hinge point between the sub-handle 2 and the handle body 1 and moves away from the front end of the handle body 1. An unlocking spring 8 is also arranged inside the handle body 1. The unlocking spring 8 is vertically arranged, with the upper end abutting against the top wall of the handle body 1 and the lower end abutting against the top of the front end of the sub-handle 2, and the position of this abutment is on the other side of the hinge point relative to the clamping portion 31. The sub-handle 2 can swing downward around the hinge point under the elastic force of the unlocking spring 8. In this embodiment, a limiting member is fixed to the top of the middle part of the sub-handle 2 through a fastener. The front side of the upper end of the limiting member has a protruding limiting portion 21. The bottom surface of the limiting portion 21 is a plane, and the front side surface of the limiting portion 21 is an inclined surface that is inclined relative to the horizontal plane, and the lower end of the inclined surface is more forward than the upper end.

[0024] The handle body 1 includes a main body 11 with a notch 11a at the bottom and a guide seat 12 fixed in the notch 11a of the main body 11 through a fastener. The rear side of the guide seat 12 has a recessed guide hole 12a that is opened in the front-rear direction. A rack 5 is horizontally penetrated through the guide hole 12a, and the rear end of the rack 5 penetrates through the guide seat 12. The front end surface of the rack 5 has a recessed hole 51 that is recessed backward. A locking spring 7 is horizontally arranged between the front end of the rack 5 and the guide seat 12. The front end of the locking spring 7 abuts against the guide seat 12, and the rear end extends into the hole 51 and abuts against the bottom surface of the hole 51. Then the rack 5 can move backward under the elastic force of the locking spring 7 and abut against the lower side surface of the limiting portion 21.

[0025] A button 6 is penetrated through the top of the main body 11. A through hole 12b is penetrated through the top of the guide seat 12. The button 6 is rotatably fixed at the through hole 12b of the guide seat 12 through a rotating shaft that horizontally penetrates through the button 6, and the bottom of the button 6 penetrates into the guide hole 12a. The bottom of the button 6 has teeth that mesh with the rack 5. In this embodiment, the top of the button 6 has a flat-shaped operating portion 61 that extends upward from the top of the handle body 1.

[0026] When the gear-pushed unlocking detachable handle needs to be disassembled, the operating part 61 is pulled backward, causing the button 6 to rotate, pushing the rack 5 to move forward against the elastic force of the locking spring 7. When the rear end of the rack 5 leaves the lower side of the limiting part 21, the positioning of the position of the secondary handle 2 is released. The secondary handle 2 swings downward around the hinge point under the elastic force of the unlocking spring 8 to expose the notch 11a. At the same time, the locking tongue 3 fixedly connected to the secondary handle 2 rotates synchronously with the secondary handle 2 around the hinge point. The clamping part 31 at the front end of the handle body 1 swings upward while the secondary handle 2 swings downward. The clamping part 31 moves away from the front end face of the handle body 1, causing the clamping opening 4 to open. The gear-pushed unlocking detachable handle can be removed from the cookware.

[0027] Conversely, when it is necessary to clamp the cookware, after the edge of the cookware is inserted into the clamping opening 4, the secondary handle 2 is swung upward to retract it into the notch 11a. The rack 5 is slightly pushed forward by relying on the inclined surface on the front side of the limiting part 21 to make way. When the limiting part 21 continues to move upward to exceed the height of the rear end of the rack 5, the rack 5 moves backward to the lower side of the limiting part 21 under the elastic force of the locking spring 7 to lock the position of the secondary handle 2. At the same time, the clamping part 31 swings downward, the clamping opening 4 shrinks and clamps the edge of the cookware to maintain the clamping state.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
