Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a detachable handle. Background Technology

[0002] Cookware typically consists of a pot body and a handle. Most pots on the market use a fixed structure to secure the handle, which means that the handle often occupies a lot of space when storing cookware. This not only wastes cabinet space but also prevents users from choosing the appropriate handle based on their needs. Although detachable handles for different pot bodies have appeared on the market, their locking and unlocking mechanisms are complex, and the design of the locking button makes it easy for users to accidentally activate the handle, causing the pot body and handle to unlock unexpectedly and creating a safety hazard.

[0003] Upon investigation, patent number CN201922177713.6 discloses a detachable pot handle, including a clamp, a handle, and two buttons on both sides of the handle. Each button has an actuator. The clamp has two blocking elements that abut against the two actuators to restrict the clamp from extending relative to the handle. Pressing the two buttons causes both actuators to move and avoid the blocking elements, allowing the clamp to extend relative to the handle. This utility model provides a detachable pot handle with good structural reliability and long service life, where the clamp can only be unlocked by pressing both buttons simultaneously, and the unlocking mechanism between the buttons and the clamp is non-elastic deformation. However, due to the complexity of the unlocking mechanism, this handle still has room for improvement. Summary of the Invention

[0004] This utility model addresses the problems of existing technology by proposing a detachable handle that is not only simple in structure and easy to assemble, but also requires both buttons to be pressed simultaneously to unlock, reducing unnecessary mechanisms and making it less prone to damage.

[0005] The technical solution of this utility model is: a detachable handle, comprising: a handle body with an internal mounting cavity, including a handle base and a handle cover, and a clamping part at the front end of the handle base;

[0006] A clamping piece with a clamping element at the front end and a hollow connecting piece at the rear, which can slide back and forth in the mounting cavity;

[0007] The feature is that a spring buckle capable of lateral deformation is fixed in the mounting cavity, and the spring buckle cooperates with the limiting teeth of the connecting piece to realize the functions of clamping and locking and popping and unlocking;

[0008] A limiting tooth, at least a pair, is distributed inside the hollow part of the connecting piece;

[0009] A spring-loaded buckle has elastic locking parts on both sides that engage with limiting teeth, with the locking parts extending outwards to form contact parts.

[0010] One button, or at least two sets, with a drive unit on the inside, which is retractable and located on both sides of the handle body, connecting or engaging with the contact part.

[0011] Furthermore, the connecting piece has a rectangular hollow section inside, and the inner side of the hollow section is provided with limiting teeth. The corresponding locking part is a vertical steel column that matches it, so as to realize the functions of elastic locking and unlocking.

[0012] Furthermore, the outer side of the abutment portion abuts against or connects with the driving portion of the button, enabling the button and the abutment portion to move together and preventing the button from shaking in the unlocked and locked states. Two sets of buttons are distributed left and right, and correspondingly, a pair of limiting teeth are distributed left and right.

[0013] Furthermore, the clamping piece has a clamping plate at the head and a connecting plate at the rear, and the clamping plate, clamping piece and connecting plate are made into one piece using metal processing technology, without the need for plastic coating process.

[0014] Furthermore, the bottom of the mounting cavity is vertically distributed with screw positioning posts and screw positioning holes, and there is also an L-shaped screw fixing plate. The through hole position of the screw fixing plate matches the screw positioning post. The positioning post passes through the spring buckle and is directly opposite to the through hole. The screw passes through the through hole and is fixed to the screw positioning post and the screw positioning hole respectively to prevent the spring buckle from shifting left, right or forward and backward.

[0015] Furthermore, the spring clip is a V-shaped spring clip, a U-shaped spring clip, or a W-shaped spring clip, meaning that the component presents a V-shape, U-shape, or W-shape when viewed from above, and is made of wound steel wire.

[0016] Furthermore, the handle base is provided with a spring groove, in which a spring is provided. One end of the spring abuts against the spring groove, and the other end is fixed to the protrusion at the end of the connecting piece, so as to always apply an outward force to the connecting piece.

[0017] Furthermore, the top of the handle cover is provided with a handle seat, and a handle is rotatably provided in the handle seat. The bottom of the handle seat is provided with an arc-shaped drive groove, and the front end of the clamping piece is provided with an oblong hole. The bottom of the corresponding handle is provided with a drive post, which passes through the arc-shaped drive groove and is fixed to each other with the oblong hole, so as to realize that rotating the handle drives the clamping piece to move back and forth.

[0018] Furthermore, the front bottom of the handle base is provided with a mounting slot, and a heat-resistant pad is fixed at the mounting slot to prevent the user from being burned.

[0019] Finally, the handle body has a mounting groove at its tail end, a base piece is fixed in the mounting groove, and a string hole is provided on the base piece.

[0020] Compared with the existing technology, the technical advantages of this application are as follows: the original structural design is converted into a spring buckle design, the process is further upgraded, the rigid connection of plastic parts is replaced with a metal connection, which not only improves the safety, but also eliminates the need for button springs, simplifies the structure, facilitates assembly, reduces costs, and is not easily damaged. At the same time, the safety standard that the original design cannot be triggered at a single point is retained. The integrated clip is used, which cannot be plastic-coated, thus simplifying the structure. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 7 A detachable handle includes: a handle body 1 with an internal mounting cavity 2, comprising a handle base 3 and a handle cover 4, the front end of the handle base 3 having a clamping part 5; a clamping piece 6 with a clamping element 7 at its front end and a hollow connecting piece 8 at its rear, which is slidably mounted in the mounting cavity 2 by means of a spring; the key improvement lies in the presence of a spring clip 9 fixed in the mounting cavity 2, which can deform laterally under pressure, and the spring clip 9 cooperates with the limiting teeth 10 of the connecting piece 8 to achieve the functions of retracting and locking the clamping piece 6 and popping it out and unlocking it; typically, There is at least one pair of limiting teeth 10, distributed inside the hollow part of the connecting piece 8; the spring buckle 9 has elastic locking parts 11 on both sides that abut against the limiting teeth 10, and the locking parts 11 extend outward to form abutting parts 12; the screw fixing plate 13 has an L-shaped cross section and at least two through holes 14 at the bottom, and the spring buckle 9 is fixed to the bottom surface of the mounting cavity by screws; there are at least two sets of buttons 15, with a driving part 16 on the inner side that abuts against or is connected to the abutting part 12, and they are telescopically arranged on both sides of the handle body 1.

[0033] The key component in this design, the spring clip, can be a V-shaped, U-shaped, or W-shaped spring clip. This means that when viewed from above, the component presents a V-shape, U-shape, or W-shape and is made of wound steel wire. However, it is not limited to these shapes. As long as there are elastic locking parts 11 on both sides that engage with the limiting teeth 10, and the locking parts 11 extend outwards to form contact parts 12, a similar effect can be achieved. This embodiment uses a simple V-shaped spring clip.

[0034] The bottom of the mounting cavity 2 has vertically distributed screw positioning posts 17 and screw positioning holes 18. The positions of the front and rear through holes 14 of the corresponding screw fixing plate 13 are matched accordingly. The screw positioning posts 17 pass through the V-shaped spring clips 9 and are aligned with the through holes 14. The screws pass through the through holes 14 and are fixed to the screw positioning posts 17 and screw positioning holes 18 respectively, preventing the V-shaped spring clips 9 from shifting left and right or front and back, and firmly fixing them to the bottom surface of the mounting cavity 2, thus preventing the unlocking and locking functions from being affected. The spring clips 9 are also limited to being fixed using the screw fixing plate 13; alternatively, they can be fixed using a groove on the bottom surface of the mounting cavity 2.

[0035] The connecting piece 8 has a rectangular cutout 21 inside. The inner side of the cutout 21 has opposing limiting teeth 10, typically arranged symmetrically from left to right. The corresponding locking part 13 is a vertical steel column that abuts against it. The outer side of the contact part 12 of the button 15 abuts against or is fixedly connected to the driving part 16 of the button 15, enabling the button 15 and the contact part 12 to move together and preventing the button 15 from shaking in the unlocked and locked states. Normally, in the free state, when the locking part 13 is located behind the limiting teeth 10 and they are interlocked, the locking function is achieved. When the user presses button 15, causing the contact part 12 to press inward, the spring buckle 9, which deforms laterally, causes the locking part 13 to press inward, thereby sliding and disengaging from the limiting tooth 10. The clamp 6 slides forward under the action of the spring, realizing the unlocking function. When the user releases his finger, in a free state, the spring buckle 9 resets and slides in the opposite direction, causing button 15 to move outward, preventing button 15 from shaking in the unlocked and locked states. When the clamp 6 moves backward to clamp the pot wall under the action of rotating handle 24, the tooth surfaces of the limiting teeth 10 arranged opposite to each other on the inner side of the hollow part 21 cooperate with the vertical steel column of the locking part 13, forcing the locking part 13 to deform and slide inward first. After the limiting teeth 10 slide past the locking part 13, the pressure of the limiting teeth 10 is released, and the locking part 13 then elastically resets and slides outward, locking the limiting teeth 10, thereby locking the clamp 6. The handle base 3 is provided with a spring groove 19, and a spring 20 is provided in the spring groove 19. One end of the spring 20 abuts against the spring groove 19, and the other end is fixed to the protrusion at the tail end of the connecting piece 8, so that an outward force is always applied to the connecting piece 8.

[0036] To facilitate manufacturing, the head of the clamping piece 6 is a clamping piece used to secure the clamping part 7, and the rear is a connecting piece 8. The clamping piece, clamping piece 6 and connecting piece 8 are made into one piece, which is stamped from a whole sheet of metal, so that there is no need for plastic coating process.

[0037] The top of the handle cover 4 is provided with a handle base 23, and a handle 24 is rotatably mounted in the handle base 23. The bottom of the handle base 23 is provided with an arc-shaped drive groove 25, and the front end of the clamp 6 is provided with an oblong hole 26. The bottom of the corresponding handle 24 is provided with a drive post 27. The drive post 27 passes through the arc-shaped drive groove 25 and is fixed to the oblong hole 26, so that rotating the handle 24 can drive the clamp 6 to move back and forth. The front bottom of the handle base 3 is provided with a mounting slot 28, and a heat-proof pad 29 is fixed at the mounting slot 28 to prevent the user from being burned. The rear end of the handle body 1 is provided with a mounting groove 30, and a base piece 31 is fixed in the mounting groove 30. The base piece 31 is provided with a lanyard hole 22.
