Abstract
Description
Technical Field
[0001] The present application relates to the technical field of kitchen utensils, and in particular to a cooker. Background Art
[0002] At present, there are many types of pots on the market with different shapes, such as frying pans, milk pans, steamers, etc., but most pots include a pot body and a handle installed on the pot body, and the handle is for the user to hold. The pot body is usually provided with a joint for the handle to be installed. After the handle is installed in the joint, the handle is fixed by screws. However, due to many cooking needs, the pot needs to be tilted up and down or left and right during long-term use, which requires the user to hold the handle to achieve this. Therefore, torque in different directions will be applied to the handle, which will easily cause the screws to loosen over time, and then cause the handle to loosen. Utility Model Content
[0003] The present application provides a cookware to solve the above-mentioned technical problem of the screws being loosened due to torque applied to the handle in certain directions.
[0004] The technical solution adopted in this application is:
[0005] A cookware comprises a cookware body, a handle and a positioning assembly for fixing the handle to the cookware body, the cookware body is provided with a connecting piece, the positioning assembly comprises a screw and a matching piece with a threaded hole, the screw is provided on the handle, the matching piece is provided on the connecting piece, a limiting convex tooth is provided at the entrance of the threaded hole, when the screw is assembled in the threaded hole, the limiting convex tooth stops the screw and limits the screw from being screwed out of the threaded hole; when the screw is assembled in the threaded hole, a gap is provided between the screw and the inner wall of the threaded hole, the gap enables the screw to tilt in a direction away from the limiting convex tooth to avoid the limiting convex tooth.
[0006] The cookware in this application also has the following additional technical features:
[0007] The limiting protruding teeth extend a predetermined length on the inner wall of the threaded hole, and the limiting protruding teeth deviate from the spiral line where the internal thread teeth of the threaded hole are located.
[0008] The limiting protrusion extends in a spiral direction on the inner wall of the threaded hole, and the spiral direction of the limiting protrusion is opposite to the spiral direction of the internal threaded teeth; or, the limiting protrusion extends in a spiral direction on the inner wall of the threaded hole, the spiral direction of the limiting protrusion is the same as the spiral direction of the internal threaded teeth, and the spiral pitch of the spiral line where the limiting protrusion is located is smaller than the spiral pitch of the spiral line where the internal threaded teeth are located.
[0009] The entrance of the threaded hole is provided with a guide protrusion, which extends along the spiral line where the internal thread teeth of the threaded hole are located. The guide protrusion can engage with the screw after the screw is tilted in a direction away from the limiting protrusion to guide the screw to be screwed into the threaded hole.
[0010] The guiding protruding teeth and the limiting protruding teeth are respectively arranged on two opposite sides of the matching piece and are staggered along the circumference of the threaded hole.
[0011] In the axial direction of the threaded hole, the guide protruding tooth and the limiting protruding tooth are located at a flush position.
[0012] In the axial direction of the threaded hole, the guide protrusion and the limiting protrusion are arranged in a staggered manner, and the distance between the guide protrusion and the internal thread of the threaded hole is smaller than the distance between the limiting protrusion and the internal thread of the threaded hole.
[0013] The projections of the limiting protruding teeth and the guiding protruding teeth on a plane perpendicular to the axial direction of the screw form a circle.
[0014] The connecting piece includes a U-shaped structure and positioning flanges folded outward from both ends of the U-shaped structure, the positioning flanges are connected to the pot body, a positioning hole is arranged in the middle of the U-shaped structure, and the matching piece is confined in the positioning hole.
[0015] A first and a second limiting protrusion are provided on the outer side of the mating piece. The first and the second limiting protrusion are arranged at intervals along the axial direction of the mating piece. The first and the second limiting protrusions are respectively stopped at the two ends of the U-shaped structure to limit the mating piece in the positioning hole.
[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are:
[0017] 1. In the pot provided by the present application, the handle is fixed to the connecting piece of the pot body through a positioning assembly. The positioning assembly includes a screw and a fitting. The screw is arranged on the handle, and the fitting is arranged on the connecting piece. Therefore, the handle can be fixed to the pot body after the screw and the fitting are in place. The entrance of the threaded hole is provided with a limiting convex tooth, so that when the screw is assembled in the threaded hole of the fitting, the limiting convex tooth stops the screw and limits the screw from rotating in the direction of screwing out of the threaded hole, thereby forming an anti-loosening design of the screw, so that the screw and the fitting are in a stable connection state, effectively improving the problem of screw loosening, and then improving the problem of handle loosening. In addition, since the limiting convex teeth are used to limit the screw from being screwed out of the threaded hole and are arranged at the entrance of the threaded hole, the limiting convex teeth will prevent the screw from being screwed into the threaded hole. The present application provides a gap between the screw and the inner wall of the threaded hole, that is, there is a gap fit between the external thread of the screw and the internal thread of the threaded hole. The gap allows the screw to have a slight lateral swing space, thereby allowing the screw to tilt in a direction away from the limiting convex teeth to avoid the limiting convex teeth. After avoiding the limiting convex teeth, the screw can be screwed into the threaded hole in a direction inclined to the axis of the threaded hole, and as the screw and the threaded hole are gradually screwed together, the screw gradually returns to the correct position. When the screw is assembled in place, the limiting convex teeth and the thread of the screw are stopped to prevent the screw from rotating in the direction of screwing out of the threaded hole.
[0018] The limiting convex tooth can be one or several protrusions, or a long convex rib extending in a certain direction, or an arc-shaped rib extending along an arc line. In short, the limiting convex tooth can be a protruding structure of any shape, which is used to resist the external thread teeth of the screw, thereby playing the function of stopping the screw.
[0019] 2. As a preferred embodiment of the present application, the limiting convex teeth extend a predetermined length, so that the limiting convex teeth are in the form of strip-shaped convex ribs, so that they have a sufficient contact area with the external thread of the screw, thereby helping to improve the stopping effect. It is understandable that the screw can only be screwed normally when the external thread groove of the screw is matched with the internal thread teeth of the threaded hole, and the limiting convex teeth deviate from the spiral line of the internal thread teeth of the threaded hole, so that the limiting convex teeth cannot be matched with the thread groove of the external thread of the screw, and then the limiting convex teeth can effectively stop the external thread of the screw.
[0020] Internal thread teeth refer to the raised structures on the internal threads in the threaded hole, and the internal thread teeth extend in a spiral. The spiral line where the internal thread teeth are located refers to an infinitely long line extending in a spiral shape around the axis of the threaded hole, and the internal thread teeth extend along the spiral line. The limiting convex teeth deviate from the spiral line of the internal thread teeth, which can be understood as the limiting convex teeth and the spiral line of the internal thread teeth partially not overlapping or not overlapping at all; it can also be understood as the limiting convex teeth and the spiral line of the internal thread teeth and the extended line formed by the continued extension of the spiral line only intersect. Since the limiting convex teeth deviate from the spiral line of the internal thread teeth, when the screw is assembled in the threaded hole, the thread groove of the external thread cannot cooperate with the limiting convex teeth, so that the external thread cannot normally engage with the limiting convex teeth, so that the limiting convex teeth can stop the screw. Specifically, for example, the limiting convex teeth can be strip-shaped convex ribs arranged on the inner wall of the threaded hole, and the limiting convex teeth extend along the circumference of the threaded hole, that is, the limiting convex teeth are located as a whole at a certain radial cross-sectional position of the threaded hole; or, the limiting convex teeth can be strip-shaped convex ribs extending in a spiral, but the spiral line of the limiting convex teeth does not overlap with the spiral line of the internal thread teeth, and the spiral line of the limiting convex teeth and the spiral line of the internal thread teeth can be two spiral lines with the same but non-overlapping rotation direction, or two spiral lines with opposite rotation directions; or the limiting convex teeth can also be strip-shaped convex ribs extending along the axial direction of the threaded hole. In short, the limiting convex teeth can extend in various directions as long as they do not completely overlap with the spiral line of the internal thread teeth.
[0021] 3. As a preferred embodiment of the present application, the extension direction of the limiting cam is opposite to the spiral direction of the internal thread teeth of the threaded hole. In other words, the limiting cam is constructed as a reverse thread opposite to the extension direction of the thread teeth of the internal thread teeth of the threaded hole. When the screw is assembled, as long as the screw tends to loosen, it will be stuck by the limiting cam to prevent further screwing out, thereby forming an effective anti-loosening method; or, although the spiral lines of the limiting cam and the internal thread teeth of the threaded hole have the same spiral direction, the spiral pitch of the spiral line where the limiting cam is located is smaller than the spiral pitch of the spiral line where the internal thread teeth are located. It can be understood that the spiral line where the limiting cam is located is denser than the spiral line where the internal thread teeth are located. The limiting cam of this structure is actually located in the gap of the extension line of the spiral line of the internal thread teeth, and can also stop the external thread of the screw.
[0022] 4. As a preferred embodiment of the present application, a guide protrusion is provided at the entrance of the threaded hole. The guide protrusion is configured to have the same rotation direction as the internal thread of the threaded hole and to be compatible with the external thread of the screw. Therefore, after the screw is tilted in a direction away from the limiting protrusion, the external thread of the screw engages with the guide protrusion, so that the guide protrusion can guide the screw to be screwed into the threaded hole, making the process of screwing the screw into the threaded hole in a tilted state smoother, thereby greatly reducing the difficulty of screwing the screw into the threaded hole.
[0023] 5. As a preferred embodiment of the present application, the guide protrusion and the limiting protrusion are respectively arranged on two opposite sides of the mating part and are staggered along the circumference of the threaded hole. The screw is tilted toward the position of the guide protrusion to prepare for being screwed into the threaded hole, while avoiding the limiting protrusion arranged opposite to the guide protrusion, thereby avoiding the interference and obstruction of the limiting protrusion in the process of the guide protrusion guiding the screw to be screwed into the threaded hole.

[0041] In the embodiments of the present application, a cooker is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all described based on the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.
[0042] Reference Figures 1 to 7As shown, a cookware provided in the present application comprises a cookware body, a handle and a positioning assembly for fixing the handle to the cookware body, the cookware body is provided with a connecting piece 1, the positioning assembly comprises a screw 2 and a matching piece 3 with a threaded hole 31, the screw 2 is provided on the handle, the matching piece 3 is provided on the connecting piece 1, a limiting convex tooth 32 is provided at the entrance of the threaded hole 31, when the screw 2 is assembled in the threaded hole 31, the limiting convex tooth 32 stops the screw 2 and limits the screw 2 from being screwed out of the threaded hole 31; when the screw 2 is assembled in the threaded hole 31, there is a gap between the screw 2 and the inner wall of the threaded hole 31, the gap allows the screw 2 to tilt in a direction away from the limiting convex tooth 32 to avoid the limiting convex tooth 32.
[0043] It should be noted that the pot body and the handle are not shown in the drawings, and the present application does not limit the specific structural form of the pot, which can be a milk pot, a frying pan, a stew pot, a frying pan, a soup pot, etc. The connecting member 1 can be integrally formed with the pot body or connected integrally by welding, or can be connected together in a detachable manner.
[0044] In the pot provided by the present application, the handle is fixed to the connecting member 1 of the pot body through a positioning assembly, and the positioning assembly includes a screw 2 and a fitting member 3. The screw 2 is arranged on the handle, and the fitting member 3 is arranged on the connecting member 1. Therefore, after the screw 2 and the fitting member 3 are in place, the handle can be fixed to the pot body. The entrance of the threaded hole 31 is provided with a limiting convex tooth 32, so that when the screw 2 is assembled in the threaded hole 31 of the fitting member 3, the limiting convex tooth 32 stops the screw 2 and limits the screw 2 from rotating in the direction of screwing out of the threaded hole 31, thereby forming an anti-loosening design of the screw 2, so that the screw 2 and the fitting member 3 are always in a stable connection state, effectively improving the problem of the screw 2 loosening, and then improving the problem of the handle loosening. In addition, since the limiting protruding teeth 32 are used to limit the screw 2 from being screwed out of the threaded hole 31 and are arranged at the entrance of the threaded hole 31, the limiting protruding teeth 32 will prevent the screw 2 from being screwed into the threaded hole 31. In the present application, a gap is provided between the screw 2 and the inner wall of the threaded hole 31, that is, a gap is provided between the external thread of the screw 2 and the internal thread teeth 33 of the threaded hole 31. The gap allows the screw 2 to have a slight lateral swing space, thereby enabling the screw 2 to tilt in a direction away from the limiting protruding teeth 32 to avoid the limiting protruding teeth 32. Figure 3 The figure shows a state where the screw 2 is tilted in a direction away from the limiting protruding teeth 32 to avoid the limiting protruding teeth 32. After avoiding the limiting protruding teeth 32, the screw 2 can be screwed into the threaded hole 31 in a direction tilted in a direction of the axis of the threaded hole 31. As the screw 2 and the threaded hole 31 are gradually screwed together, the screw 2 gradually returns to the normal position. Figure 4 The figure shows the state where the screw 2 is assembled in place. When the screw 2 is assembled in place, the limiting protruding teeth 32 and the thread of the screw 2 are stopped to prevent the screw 2 from rotating in the direction of screwing out of the threaded hole 31 .
[0045] In order to achieve effective stopping of the screw 2 by the limiting protruding teeth 32, as a preferred embodiment, as Figure 2 and Figure 5 As shown, the limiting protruding teeth 32 are arranged on the inner wall of the threaded hole 31, and extend in a spiral direction around the axis of the threaded hole 31 as a whole, and the limiting protruding teeth 32 deviate from the spiral line of the internal threaded teeth 33 of the threaded hole 31. It can be understood by those skilled in the art that in order to ensure that the screw 2 can be screwed into the threaded hole 31, the rotation direction of the internal threaded teeth 33 of the threaded hole 31 needs to be adapted to the rotation direction of the external thread of the screw 2. However, the present application makes the extending direction of the limiting protruding teeth 32 deviate from the spiral line of the internal threaded teeth 33 of the threaded hole 31, so that the limiting protruding teeth 32 cannot mesh with the external thread of the screw 2, and can form an effective stop for the external thread of the screw 2 when the screw 2 and the threaded hole 31 are screwed into place and rotate in the reverse direction to loosen. In addition, the limiting protruding teeth 32 are arranged along the spiral line as a whole. The threaded hole 31 is extended in the direction of rotation, and can be directly processed by the equipment for processing threads, so the processing is also relatively convenient; in addition, it is also convenient for the screw 2 to be easily avoided by the screw 2 during assembly. At the same time, the limiting convex tooth 32 is extended to a certain length, and the area cooperating with the screw 2 stopper can be increased, thereby improving the stopping effect. In order to facilitate the screw 2 to tilt and avoid the limiting convex tooth 32, on the premise of ensuring that the limiting convex tooth 32 effectively stops the screw 2, the arc length of the limiting convex tooth 32 extending along the circumference of the threaded hole 31 should be less than the circumference of the threaded hole 31, thereby providing avoidance space for the screw 2 to tilt.
[0046] In a preferred embodiment, the extension direction of the limiting protrusion 32 is opposite to the spiral direction of the internal thread teeth 33 of the threaded hole 31. In other words, the limiting protrusion 32 is constructed as a reverse thread tooth that is opposite to the extension direction of the thread tooth of the internal thread teeth 33 of the threaded hole 31. When the screw 2 is assembled, as long as the screw 2 tends to loosen, it will be stuck by the limiting protrusion 32 to prevent further unscrewing, thereby forming an effective anti-loosening effect.
[0047] As a preferred implementation of the present application, Figures 2 to 5As shown, the entrance of the threaded hole 31 is provided with a guide protruding tooth 34, and the guide protruding tooth 34 extends in the spiral direction, and the guide protruding tooth 34 extends along the spiral line of the internal threaded tooth 33. The guide protruding tooth 34 has the same spiral direction as the internal thread of the threaded hole 31, and the guide protruding tooth 34 is adapted to the external thread of the screw 2. The guide protruding tooth 34 guides the screw 2 to be screwed into the threaded hole 31 after the screw 2 is tilted in the direction away from the limiting protruding tooth 32. Those skilled in the art can understand that, in order to avoid the limiting convex teeth 32, the installation process of the screw 2 in an inclined state toward the threaded hole 31 reduces the adaptability with the internal thread teeth 33 of the threaded hole 31, and is thus hindered to a certain extent by the internal thread teeth 33. Therefore, the present application provides a guide convex tooth 34, and the guide convex tooth 34 is configured to have the same rotation direction as the internal thread of the threaded hole 31 and to be adapted to the external thread of the screw 2, so that after the guide convex tooth 34 is tilted in a direction away from the limiting convex tooth 32, the external thread of the screw 2 engages with the guide convex tooth 34, and is screwed into the threaded hole 31 under the guidance of the guide convex tooth 34, so that the process of the screw 2 being screwed into the threaded hole 31 in the inclined state is smoother, thereby greatly reducing the difficulty of screwing the screw 2 into the threaded hole 31. In a preferred embodiment, in order to further enhance the guiding effect of the guide protrusion 34 on the screw 2, the extension direction of the guide protrusion 34 can be made the same as the spiral direction of the internal thread teeth 33 of the threaded hole 31. In other words, the guide protrusion 34 is constructed as a forward thread tooth with the same extension direction as the thread tooth of the internal thread teeth 33 of the threaded hole 31, so that the guide protrusion 34 and the external thread of the screw 2 can be engaged, thereby guiding the screw 2 to be screwed into the threaded hole 31.
[0048] The guide protruding teeth 34 and the limiting protruding teeth 32 are both arranged at the entrance of the threaded hole 31. Regarding the arrangement of the two in the circumferential direction of the threaded hole 31, in a preferred embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, the guide protruding teeth 34 and the limiting protruding teeth 32 are respectively arranged on two opposite sides of the mating member 3, and are arranged in a staggered manner along the circumference of the threaded hole 31. Through this arrangement, the guide protruding teeth 34 and the limiting protruding teeth 32 are in a relatively arranged separated state in the entrance of the threaded hole 31, so that the screw 2 tilts toward the position where the guide protruding teeth 34 are located to prepare for screwing into the threaded hole 31, while avoiding the limiting protruding teeth 32 arranged opposite to the guide protruding teeth 34, thereby preventing the guide protruding teeth 34 from interfering with and hindering the limiting protruding teeth 32 in the process of guiding the screw 2 to screw into the threaded hole 31.
[0049] Regarding the arrangement of the guide protruding teeth 34 and the limiting protruding teeth 32 in the axial direction of the threaded hole 31, in a preferred embodiment, as shown in FIG. Figure 2As shown, in the axial direction of the threaded hole 31, the guide protruding teeth 34 and the limiting protruding teeth 32 are located at a flush position. In other words, the distances between the guide protruding teeth 34 and the limiting protruding teeth 32 and the internal threaded teeth 33 are equal, and the distances between the guide protruding teeth 34 and the limiting protruding teeth 32 and the end faces of the threaded hole 31 are also equal. Through this arrangement, the screw 2 only needs to be tilted at a small angle to avoid the limiting protruding teeth 32 while cooperating with the guide protruding teeth 34, thereby reducing the difficulty of screwing the screw 2 into the threaded hole 31. As an alternative embodiment, in the axial direction of the threaded hole 31, the guide protruding teeth 34 and the limiting protruding teeth 32 can also be arranged in a staggered manner, and the distance between the guide protruding teeth 34 and the internal threaded teeth 33 of the threaded hole 31 is smaller than the distance between the limiting protruding teeth 32 and the internal threaded teeth 33 of the threaded hole 31. The guide protruding teeth 34 and the limiting protruding teeth 32 are arranged in a staggered manner. In other words, the distances between the guide protruding teeth 34 and the limiting protruding teeth 32 and the internal threaded teeth 33 are not equal, and the distances between the guide protruding teeth 34 and the limiting protruding teeth 32 and the end faces of the threaded holes 31 are also not equal, which facilitates the staggered processing of the guide protruding teeth 34 and the limiting protruding teeth 32, facilitates production and processing, and reduces the processing difficulty. The distance between the guide protruding teeth 34 and the internal threaded teeth 33 is smaller than the distance between the limiting protruding teeth 32 and the internal threaded teeth 33, that is, the guide protruding teeth 34 are closer to the internal threaded teeth 33, making it easier to guide the screw 2.
[0050] Furthermore, if Figure 5 As shown, the projections of the limiting convex teeth 32 and the guiding convex teeth 34 on a plane perpendicular to the axial direction of the screw 2 form a circle. In other words, the projections of the limiting convex teeth 32 and the guiding convex teeth 34 are respectively semi-circular arc structures, and the projections of the two are connected end to end to form a circle, so that the limiting convex teeth 32 and the guiding convex teeth 34 are relatively arranged and circumferentially staggered, and their respective extension lengths are extended as much as possible, thereby effectively improving the guiding effect of the guiding convex teeth 34 and the stopping and limiting effect of the limiting convex teeth 32.
[0051] As a preferred implementation of the present application, Figure 1 and Figure 6 As shown, the connector 1 includes a U-shaped structure 11 and positioning flanges 12 folded outward from both ends of the U-shaped structure 11, the positioning flanges 12 are connected to the pot body, a positioning hole 111 is provided in the middle of the U-shaped structure 11, and the matching piece 3 is limited in the positioning hole 111. The connector 1 is constructed as a U-shaped structure 11, which provides sufficient space for the installation of the matching piece 3, and the positioning flanges 12 are convenient for the reliability of the connector 1 and the pot body.
[0052] Regarding the limiting method of the fitting member 3 on the connecting member 1, in a preferred embodiment, as shown in FIG. Figure 1 , Figure 6 and Figure 7 As shown, the outer side of the mating piece 3 is provided with a first limiting protrusion 35 and a second limiting protrusion 36, the first limiting protrusion 35 and the second limiting protrusion 36 are arranged at intervals along the axial direction of the mating piece 3, and the first limiting protrusion 35 and the second limiting protrusion 36 are respectively stopped at both ends of the U-shaped structure 11 to limit the mating piece 3 in the positioning hole 111. Through the stopping and limiting of the first limiting protrusion 35 and the second limiting protrusion 36, the mating piece 3 is reliably and stably installed in the positioning hole 111 of the connecting piece 1, thereby ensuring the stable matching of the screw 2 and the mating piece 3, and improving the firmness of the handle installation.
