Description

TECHNICAL FIELD

[0001] The utility model relates to food processing equipment technical field especially, it is a kind of thick thin adjusting mechanism of food cutter. BACKGROUND

[0002] An important link in the food processing process of fruits and vegetables and other food materials is to cut the food materials into the required shape. Usually, food cutting is mainly through two ways of manual cutting and food cutting machine, however, the efficiency of manual cutting is low, and the structure of the existing food cutting machine is complex, and the operation is relatively cumbersome, which is not suitable for household use. Household food cutter becomes the choice of more and more families for fruit and vegetable cutting because of its simple operation and high efficiency.

[0003] The width or thickness of the food cut by the existing household food cutter is determined by the distance between the cutter and the end face of the shell. To meet the different needs of different people and different dishes for the width and thickness of food materials, the Chinese utility model patent with the patent number ZL202022899107.8 (the authorized announcement number is CN213732092U) discloses an adjusting structure. The adjusting mechanism includes a shell, a sliding member slidingly connected with the shell, and a driving part. The distance between the cutter and the shell is adjusted by driving the sliding member to slide along the shell through the driving part, so that food of different width or thickness can be cut.

[0004] However, the driving part of the above-mentioned adjusting mechanism includes a knob and a connecting column. The lower end of the knob is provided with three connecting blocks. The knob and the connecting column are detachably connected through the cooperation of the clamping grooves on the connecting blocks and the clamping blocks on the inner wall of the connecting column. Although the clamping connection can connect the knob and the connecting column, in long-term use, as the knob and the connecting column age, the cooperation between the clamping grooves and the clamping blocks will become loose, causing the knob to loosen. When the knob is rotated, it is difficult to drive the connecting column to rotate and drive the sliding member to slide along the shell. Even the clamping blocks fall off, causing the knob to be unable to be connected to the connecting column. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to provide a thick and thin adjusting mechanism of food cutter with firm connection between the knob and the connecting column in view of the above-mentioned existing technology status.

[0006] The technical scheme adopted by the utility model to solve the above-mentioned technical problem is as follows: the thick and thin adjusting mechanism of food cutter includes a shell and an adjusting plate provided in the shell and movably matched with the shell. A driving assembly for driving the adjusting plate to slide relative to the shell is threadedly connected to the adjusting plate. The driving assembly includes a transmission column and a knob provided on the top surface of the transmission column. The knob and the transmission column are mutually inserted and matched, and connected through a fastener.

[0007] In order to facilitate the mutual insertion of the knob and the transmission column, preferably, the top surface of the transmission column is provided with at least two positioning insertion holes, and the back surface of the knob is correspondingly provided with insertion columns matched with the positioning insertion holes, or the back surface of the knob is provided with at least two positioning insertion holes, and the top surface of the transmission column is correspondingly provided with insertion columns matched with the positioning insertion holes, and the insertion columns are inserted into the positioning insertion holes to mutually insert the knob and the transmission column. The insertion of the at least two positioning insertion holes and the insertion columns can limit the rotation between the knob and the transmission column, and convert the rotation of the knob into the sliding of the adjusting plate relative to the shell under the transmission of the transmission column.

[0008] In order to connect the knob and the transmission column, preferably, the fastener is a screw, the knob is provided with a first connecting hole, the transmission column is provided with a second connecting hole, and the screw is sequentially inserted through the first connecting hole and the second connecting hole to connect the knob to the transmission column. The screw connection mode makes the connection between the knob and the transmission column firm, and avoids the problem of connection failure caused by aging of the buckle connection in the prior art.

[0009] In order to avoid the exposure of the screw thread on the outer surface of the knob, preferably, the knob is further provided with a cover member capable of covering the screw. The cover member can cover the screw, avoid the exposure of the screw, and increase the aesthetics of the knob.

[0010] Further, the top periphery of the transmission column has an inwardly recessed step, the shell has an extension portion extending into the step and limiting the transmission column in the shell, the extension portion is provided with at least two circumferentially arranged tooth grooves, and the drive assembly further comprises an elastic damping member arranged on the transmission column and elastically abutting against the tooth grooves. In this way, when the knob rotates, the elastic damping member and the surface of the tooth grooves generate discontinuous friction vibration, which can increase the rotational damping and obtain sound feedback, thereby improving the hand feeling when the knob rotates.

[0011] In order to make the elastic damping member elastically abut against the tooth grooves, preferably, the tooth grooves are arranged on the side surface of the extension portion, the elastic damping member comprises a click pin radially movably arranged on the transmission column, and an elastic member acting between the click pin and the transmission column, and the elastic member makes the head of the click pin always have a tendency to abut against the tooth grooves. In this way, the elastic force of the elastic member acts on the click pin to make the head of the click pin always have a tendency to abut against the tooth grooves, thereby making the click pin and the tooth grooves generate discontinuous friction vibration, and the arrangement of the tooth grooves on the side surface of the extension portion and the radial arrangement of the click pin can reduce the size of the knob, and make the food cutter structure more compact. Of course, the tooth grooves can be arranged on the outer surface or the inner surface of the extension portion, and the axial arrangement of the click pin can also be used as a setting mode of the elastic damping member.

[0012] Further, a mounting groove for accommodating the elastic damping member is arranged radially on the transmission column, a tail portion of the click pin is partially extended outward to form a connecting portion, the elastic member is a compression spring which is sleeved on the connecting portion and the two ends of the compression spring are respectively abutted against the tail portion of the click pin and the transmission column. The mounting groove accommodates the elastic damping member therein, so that the elastic member or the click pin is prevented from being deviated when the knob is rotated, and the reliability of the structure is increased.

[0013] Further, a limiting block for limiting the limiting block is arranged in the limiting groove. The limiting block is arranged to limit the rotation angle of the knob, so that the transmission column is prevented from being separated from the threaded hole due to too large rotation angle of the knob or the external thread of the transmission column and the internal thread of the threaded hole are prevented from being slipped due to too large reverse rotation angle.

[0014] Further, a limiting block for limiting the limiting block is arranged in the limiting groove. The limiting block is arranged to limit the rotation angle of the knob, so that the transmission column is prevented from being separated from the threaded hole due to too large rotation angle of the knob or the external thread of the transmission column and the internal thread of the threaded hole are prevented from being slipped due to too large reverse rotation angle.

[0015] Compared with the prior art, the food cutter has the following advantages: the knob and the transmission column are connected to each other by the connection mode of mutual insertion and connection through fasteners, so that the connection between the knob and the transmission column is more reliable, the torque that can be borne by the knob and the transmission column is increased, and the problem of connection failure caused by aging of the buckle in the prior art is avoided.

[0022] The utility model will be further described in detail below in combination with the embodiment of the figure.

[0023] As Figures 1-6 shown, it is a preferred embodiment of the utility model. The thickness adjusting mechanism of the food cutter of this embodiment comprises a shell 1 and an adjusting plate 2 arranged in the shell 1 and slidably connected with the shell 1. Among them, the adjusting plate 2 is threadedly connected with a driving assembly 3 for driving the adjusting plate 2 to slide relative to the shell 1, the driving assembly 3 comprises a transmission column 31 and a knob 32 arranged on the top surface of the transmission column 31, the back surface of the adjusting plate 2 has a threaded hole 21, and the transmission column 31 has an external thread that is in transmission cooperation with the internal thread of the threaded hole 21. When the adjusting mechanism needs to be adjusted, rotate the knob 32 clockwise to drive the transmission column 31 to rotate, and under the transmission cooperation of the internal thread of the threaded hole 21 and the external thread of the transmission column 31, the adjusting plate 2 slides relative to the shell 1 in the direction away from the cutting assembly in the food cutter, the distance between the adjusting plate 2 and the cutting assembly becomes larger, at this time the food can be cut into thicker pieces; on the contrary, rotate the knob 32 counterclockwise, the adjusting plate 2 slides relative to the shell 1 in the direction close to the cutting assembly in the food cutter, the distance between the adjusting plate 2 and the cutting assembly becomes smaller, at this time the food can be cut into thinner pieces.

[0024] In order to connect the knob 32 and the transmission column 31 firmly and transmit effectively, the knob 32 and the transmission column 31 of this embodiment are mutually inserted and matched, and are connected through fasteners. Specifically, as Figures 4-5 shown, the top surface of the transmission column 31 is provided with three positioning insertion holes 311, and the back surface of the knob 32 is correspondingly provided with three insertion columns 321 matched with the positioning insertion holes 311, the insertion columns 321 are inserted into the positioning insertion holes 311 to mutually insert and match the knob 32 and the transmission column 31. In this embodiment, the fastener is selected as a screw 34, the knob 32 is provided with a first connecting hole 322, the transmission column 31 is provided with a second connecting hole 312, and the screw 34 passes through the first connecting hole 322 and the second connecting hole 312 in sequence to connect the knob 32 on the transmission column 31. The three positioning insertion holes 311 and the insertion columns 321 are matched in the mode of insertion to limit the rotation between the knob 32 and the transmission column 31, so that the transmission column 31 can convert the rotation of the knob 32 into the sliding of the adjusting plate 2 relative to the shell 1 through the threaded connection with the adjusting plate 2, and the connection between the knob 32 and the transmission column 31 is firm through the screw 34, avoiding the problem of connection failure caused by the aging of the buckle connection in the prior art. In addition, the knob 32 is also provided with a cover 35 capable of covering the screw 34 to make the knob 32 more beautiful.

[0025] Referring to Figures 3-4, the top periphery of the transmission column 31 has an inner recessed step 313, the housing 1 has an extension 11 extending into the step 313 and limiting the transmission column 31 in the housing 1, the side surface of the extension 11 has a plurality of circumferentially arranged tooth grooves 111, the drive assembly 3 further comprises a resilient damping member 33 arranged on the transmission column 31 and resiliently abutting against the tooth grooves 111. Specifically, referring to Figure 6 , the resilient damping member 33 comprises a click pin 331 radially movably mounted on the transmission column 31 and a spring 332 acting between the click pin 331 and the transmission column 31, in this embodiment, the click pin 331 is a cylinder with a spherical head at the end surface, which can also be replaced by a steel ball, and the spring 332 is a compression spring, which makes the head 331a of the click pin 331 always have a tendency to abut against the tooth grooves 111. In this way, the elastic force of the compression spring acts on the click pin 331 to make the head 331a of the click pin 331 always have a tendency to abut against the tooth grooves 111, so that when the knob 32 rotates, the click pin 331 and the tooth grooves 111 produce discontinuous friction vibration, increasing the rotation damping while obtaining sound feedback, thereby improving the hand feeling when the knob 32 rotates. The radial arrangement of the click pin 331 can reduce the size of the knob 32 and make the food cutter structure more compact. In addition, the transmission column 31 is radially provided with a mounting groove 314 for accommodating the resilient damping member 33, the tail 331b of the click pin 331 partially extends outward to form a connecting portion 333, the compression spring is sleeved on the connecting portion 333, and the two ends are respectively abutted against the tail 331b of the click pin 331 and the transmission column 31. The mounting groove 314 avoids the elastic member 332 or the click pin 331 from being deviated when the knob 32 rotates, increasing the reliability of the structure.

[0026] In addition, in order to avoid the outer thread of the transmission column 31 and the inner thread of the threaded hole 21 from slipping or the transmission column 31 from being pulled out of the threaded hole 21 when the knob 32 rotates clockwise at too large an angle or counterclockwise at too large an angle, the bottom of the knob 32 extends downward to form a limiting block 323, the extension 11 has an arc-shaped limiting groove 112, the limiting block 323 extends into the limiting groove 112 and slidably cooperates with the limiting groove 112, and the limiting groove 112 is provided with a stop block 113 limiting the limiting block 323. The limiting groove 112 limits the limiting block 323 therein and can only slide in the limiting groove 112, thereby limiting the rotation path of the knob 32 and avoiding the deviation of the knob 32 when rotating. The stop block 113 can limit the rotation angle of the knob 32 to avoid the above-mentioned problem of too large rotation angle.
