[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] Please see Figure 1-5 The present application provides a linkage lifting seat for a food processor barrel, which includes a fixed seat 1, an upper fork portion 2 and a lower fork portion 3. The upper fork portion 2 is slidably connected to the base 1 up and down, the upper fork portion 2 is used to support the barrel, and the lower fork portion 3 is pivotally connected to the upper fork portion and arranged below it. Specifically, the upper fork portion and the lower fork portion are pivotally connected through a pivot connection, and the upper fork portion and the lower fork portion are provided with an axial hole that cooperates with the pivot connection. A linkage structure is arranged between the lower fork portion 3 and the upper fork portion 2, with the aid of which the lower fork portion can switch and maintain the upper fork portion 2 between a raised state and a lowered state, the linkage structure comprising a linkage block 4, an upper pull rod 5 and a lower pull rod 6, the upper fork portion having a connecting portion 21, the lower fork portion 3 having a connecting arm 31, the linkage block 4 being pivotally connected to the connecting portion 21, the first end of the upper pull rod 5 and the first end of the lower pull rod 6 respectively, the second end of the lower pull rod 6 being pivotally connected to the connecting arm 31, the fixed seat 1 being provided with a hole 7 for the second end of the upper pull rod 5 to pass through, the upper pull rod 5 being provided with a spring member 8 at the second end thereof for abutting against the upper end of the hole, and the fixed seat 1 being provided with a positioning portion 9 for abutting against the upper end surface of the connecting portion 21.

[0024] When in use, when the upper fork is in the raised state, the user presses down the lower fork, and the lower fork rotates downward relative to the upper fork, and at the same time drives the lower pull rod pivotally connected to the lower fork, and the lower pull rod drives the linkage block to rotate and causes the connecting portion 21 to disengage from the positioning portion 9. During the rotation of the linkage block, the upper pull rod is pulled to compress the spring and the second end of the upper pull rod is held against the fixed seat, maintaining the lowered state of the upper fork, thereby completing the switching of the upper fork to the lowered state. For details, please refer to the attached Figure 2 and 4 When the upper fork is in the descending state, the user pushes the lower fork upward to rotate the lower fork upward relative to the upper fork, and at the same time drives the lower pull rod pivoted with the lower fork to retract. During the retraction process of the lower pull rod, the linkage block is driven to rotate back until the connecting portion 21 abuts against the positioning portion 9. In this process, the upper pull rod is also driven to retract by the linkage block, so that the second end of the upper pull rod leaves the fixed seat. The elastic force of the spring member can prevent the upper pull rod from being easily driven by the moving block, and can play a role in keeping the upper fork in the lifted state. For details, please refer to the attached Figure 1 and 3 .

[0025] The positioning portion 9 is an eccentric wheel, which is rotatably connected to the fixed seat 1. When the barrel is placed on the upper fork, there may be a slight installation deviation, so when the upper fork lifts the barrel, the barrel still has a small range of shaking. At this time, after the upper fork is switched to the lowered state, the eccentric wheel is rotated to adjust the height of the abutment point when the eccentric wheel and the connecting portion abut, thereby compensating for the slight installation deviation and solving the problem of unstable installation of the barrel.

[0026] The front side of the eccentric wheel 9 is provided with an adjustment hole 91, and the front side of the fixing seat 1 is provided with an avoidance opening corresponding to the position of the adjustment hole, so that the user can rotate and adjust the eccentric wheel in front of the fixing seat. The fixing seat 1 is provided with a fastening screw 10 for pressing the eccentric wheel. Under the action of the fastening screw, it can be ensured that the eccentric wheel is not easily affected by external force and rotates after the position is adjusted each time. It should be noted that the external force referred to here is the force during non-artificial adjustment and rotation.

[0027] When the upper fork 2 is in a raised state, the lower fork 3 is arranged close to the lower end of the upper fork, and the front end of the lower fork 3 has an operating part 11 extending from the front end of the upper fork. The user can only switch the raised state of the upper fork to the lowered state through the operating part. The lower fork is set with this structure, so that the lower fork can be hidden to avoid the situation where the upper fork is switched from the raised working state to the lowered state due to accidental touching of the lower fork; when the upper fork 2 is in a lowered state, the front end of the lower fork opens downward to form an angle a with the upper fork, and the angle a is 1°-90°, preferably 20°, 25°, 30°, 40°, 45° and the like. The specific selection is based on actual needs. The user only needs to push up the lower fork to easily switch the lowered state of the upper fork to the raised state.

[0028] In actual use, when the upper fork portion in the raised state needs to be switched to the lowered state, the user usually presses down the lower fork portion by stepping on it. Therefore, setting the upper end surface of the operating portion 11 as an inclined surface tilted downward toward the front can make it more convenient to use by stepping on it.

[0029] The fixing seat 1 is provided with a first sliding structure 12 on both sides, and the upper fork portion 2 is provided with a second sliding structure 13 that slides in cooperation with the first sliding structure on both sides. The first sliding structure and the second sliding structure are respectively the cooperation of a slide rail and a slide groove.

[0030] The linkage block 4 is provided with a force-bearing bracket 14 extending downward, and the fixed seat 1 is provided with a telescopic cylinder 15 corresponding to the bottom end of the force-bearing bracket. When the upper fork part switches from a raised state to a lowered state, the force-bearing bracket will be pressed downward and contact with the telescopic cylinder, and the reverse thrust force of the telescopic cylinder can slow down the descending speed of the upper fork part.

[0031] The upper fork portion 2 is provided with a positioning structure 16 on its supporting surface, and the positioning structure can specifically be a positioning column.

[0032] See attached Figure 6 The back of the fixing seat 1 is provided with a protective shell 17 arranged around the linkage structure. The protective shell is installed on the fixing seat 1 by screws, and the protective shell can play a role in protecting the linkage structure.

[0033] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
