Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a connecting structure, a stirring part and a chef machine. Background Art

[0002] There are basically two types of automatic disassembly structures for stirrer stirring blades on the market. One is to inlay a magnetic strip on the head of the stirring blade, and fasten it to the rotating shaft of the motor through the mutual attraction between the magnetic strip and the rotating shaft of the motor. When disassembling, the stirring blade can be removed as long as the disassembly force is greater than the attraction force. However, this structure fastened by magnetic force will cause the magnetic force to disappear or weaken at a relatively high temperature. There is also an automatic disassembly structure for the stirring blade of a cooking machine, in which a rectangular through hole is opened on the upper surface and side wall of the stirring blade head, and the rectangular through holes on the upper surface and side wall of the stirring blade head are connected at the bottom; a horizontal shaft pin is fastened to the lower end of the motor shaft, and the horizontal shaft pin is inserted from the rectangular hole on the upper surface of the stirring blade head, and then rotated in a clockwise or counterclockwise direction for a certain angle, and a hole slot is opened in the upper direction of the stop position, and the gravity of the stirring blade is used to clamp the horizontal shaft pin in the upper hole slot. However, this structure has a hidden problem when used in a cooking machine. When cooking, if there is a foreign object under the stirring blade, the stirring blade will be lifted up and then fall off during rotation. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0042] The technical solution of the utility model is described in detail below with specific embodiments.

[0043] Reference Figures 1 to 20A connection structure includes a first connection body and a second connection body connected to the first connection body, wherein the first connection body includes a connection column 11 that passes through the second connection body; the second connection body includes a connection body body 21, a channel 22 that provides a space for the connection column 11 to pass through and axially limit the connection column 11, and a limiting module that is connected to the connection body body 21 and limits one end of the connection column 11. The connection column 11 passes through the channel 22, and the limiting module is set to limit one end of the connection column 11, so that the connection column 11 is limited in the axial direction of the connection structure, and the limiting module is used to limit the connection column 11 twice, so as to achieve the effect of multiple limiting of the connection column 11 in the axial and circumferential directions, thereby improving the connection stability of the first connection body and the second connection body, avoiding the problem of the prior art that the foreign matter below lifts the stirring blade and causes axial movement to release the connection between the two, and avoiding the problem of magnetic retrieval affecting the connection stability of the two under high temperature conditions. The connection structure is simple to disassemble and install and easy to implement.

[0044] A limiting column 111 is disposed at one end of the connecting column 11 . The limiting column 111 is disposed through the channel 22 . The interior of the limiting module conflicts with the exterior of the limiting column 111 that penetrates the channel 22 . The limiting column 111 and the connecting column 11 are arranged perpendicular to each other; after the connecting column 11 passes through the channel, the limiting column 111 is rotated to make it conflict with the inside of the channel 22 in the axial direction, thereby achieving the limitation of the limiting column 111 in the axial direction, and the inner surface of the limiting module conflicts with the outer surface of the limiting column 111, so that the limiting module continues to limit the limiting column 111 in the circumferential direction to prevent the limiting column 111 from rotating too much and rotating until it is parallel to the channel 22 as a whole and escapes from the channel 22, and the limiting column 111 is limited in the circumferential direction so that the limiting column 111 continues to conflict with the inside of the channel 22, thereby achieving the effect of axial limitation and circumferential limitation, and improving the connection stability of the first connector and the second connector.

[0045] The limiting module includes an elastic part 31 connected to the connector body 21 at one end, and a limiting part 32 connected to one end of the elastic part 31, wherein the interior of the limiting part 32 conflicts with the exterior of the limiting column 111; with the axis of the connector body 21 as the axis, when the limiting column 111 is in the channel 22, the limiting part 32 limits the limiting column 111 in the axial and circumferential directions, and the limiting part 32 is provided with a connecting part 33 connected to one end of the elastic part 31, and the connecting part 33 is connected to the connector body 21. The interior of the limiting part 32 faces the exterior of the limiting column 111, and the elastic part 31 includes a spring and a spring sheet. The elastic part 31 continuously applies a downward force to the limiting part 3232, so that when the limiting part 32 is in the connection state between the first connector and the second connector, the limiting part 32 continuously limits the limiting column 111 in the axial or circumferential direction. The connecting portion 33 is sheet-shaped, and the connecting body 21 is provided with an interlocking groove 212 for the connecting portion 33 to be interlocked and connected, so that the connecting body 21 after the connecting portion 33 is connected is flush with the upper end surface of the connecting portion 33, wherein the limiting portion 32 is arranged below the connecting portion 33, and the connecting portion 33 is arranged above the groove 23, so as to limit the maximum rising stroke of the limiting portion 32 in the axial direction; the maximum descending stroke of the limiting portion 32 in the axial direction under the action of the spring is limited by the upper end resistance of the second channel 222.

[0046] One end of the limiting portion 32 is connected to a handle 34 that penetrates the connector body 21 and extends to the outside. The handle 34 is coaxially arranged with the spring. By moving the handle, the force of the spring is overcome to move the limiting portion 32, thereby releasing the limit on the connecting column 11, and facilitating the release of the connection state between the first connector and the second connector. The handle 34 is arranged and extends to the outside, so that when the limiting portion 32 contacts the limiting column 111, the limiting module is prevented from shaking left and right, thereby improving the stability of the limiting effect on the circumferential direction of the limiting column 111.

[0047] The connector body 21 is provided with a groove body 23 that provides axial movement space for the limiting part 32 and the elastic part 31. The groove body 23 is provided to provide space for the limiting part 32 and the elastic part 31 to move axially, wherein the handle 34 is coaxially arranged with the elastic part 31 and penetrates the connector body 21 to the outside, so that the limiting module can only move in the axial direction, and the limiting part is in a relatively fixed position under the dual action of the handle 34 penetrating the connection of the connector body 21 and the groove body 23, so that the limiting column 111 is in a relatively fixed position when limiting, thereby improving the connection stability between the first connector and the second connector.

[0048] The cross-sectional shape of the limiting portion 32 is a "冂"-shaped. The "冂"-shaped limiting portion 32 limits the circumferential direction of the limiting column body 111 on both sides, and the upper side cooperates with the elastic portion 31 to limit the limiting column body 111 in the axial direction. The lower part is hollowed out to facilitate the removal when disassembling and to cooperate with the connecting body main body 21 for limiting when connecting.

[0049] The channel 22 includes a first channel 221 arranged along the axial direction of the connecting body main body 21 and a second channel 222 arranged along the radial direction of the connecting body main body 21 and communicating with the first channel 221;

[0050] The connecting body main body 21 is provided with a limiting block 213. The limiting block 213 is arranged on one side of the first channel 221, and the second channel 222 is arranged at the lower end of the limiting block 213. The connecting column 11 penetrates through the first channel 221, and the limiting column body 111 is arranged at the end of the connecting column 11 and extends along the direction of the second channel 221. The lower end surface of the limiting block 213 faces the upper end surface of the limiting column body 111. Since the first channel 221 and the second channel 222 are arranged perpendicular to each other, after the connecting column 11 provided with the limiting column body 111 is inserted through the first channel 221, the limiting column body 111 is rotated into the second channel 222. After moving the handle 34 to lift the limiting portion 32, the limiting column body 111 is further rotated to the position directly below the limiting portion 32. After releasing the handle 34, due to the elastic portion 31, the limiting portion 32 moves so that the inner surface of the limiting portion 32 abuts against the outer surface of the limiting column body 111, thereby enabling the limiting portion 32 to limit the limiting column body 111 in the circumferential direction and the axial direction. Due to the provision of the limiting block 213, the limiting block 213 is arranged on one side of the first channel 221, the limiting column body 111 extends from the connecting column 11 passing through the first through hole 221 to the second channel 222, the second channel 222 is arranged at the lower end of the limiting block 213, and the lower end surface of the limiting block 213 corresponds to the upper end surface of the limiting column body 111 in the axial direction, so that the limiting column body 111 is prevented from moving axially under the blockage of the limiting block 213. Since the rotation of the limiting column body 111 is restricted by the limiting portion 32, the limiting column body 111 is continuously in the position where it is blocked from moving axially by the limiting block 213. The connection stability between the first connecting body and the second connecting body is improved. When it is necessary to disconnect the first connecting body and the second connecting body, move the handle 34 and rotate the limiting column body 111 so that the connecting column 11 is parallel to the first channel 221 in the overall axial direction, and then pull out the connecting column 11. This disassembly and assembly method is simple and easy to implement.

[0051] The connector body 21 is provided with a conflicting groove 214 that conflicts with the lower end of one side of the limiting part 32. Specifically, the connector body 21 is provided with a conflicting groove 214 that conflicts with the lower end of one side of the limiting part 32 at the second channel 222. The conflicting groove 214 is provided to cooperate with the connection where the handle 34 passes through the connector body 21. During the rotation process, the limiting module is subjected to the force of the limiting column 111 in the circumferential direction. The conflicting groove 241 is provided to allow the limiting part 32 to be blocked by a step at one end, which can effectively improve the stability of the conflict; at the same time, it cooperates with the connection where the handle 34 passes through the connector body 21, and the two ends in the circumferential direction are respectively limited. Multiple limits improve the stability of the limit module, thereby improving the connection stability of the first connector and the second connector.
