Detailed implementation manners

[0022] The present utility model will be further described below with specific embodiments in conjunction with the accompanying drawings. Refer to Figures 1-5 :

[0023] A locking structure for the knife plate 2 of a vegetable cutter, comprising a base 1 and a knife plate 2. A locking seat 3 is slidably arranged in the base 1. A locking protrusion 4 for locking with the locking groove of the knife plate 2 is arranged at the front end of the locking seat 3. A first driving mechanism for driving the locking seat 3 to move forward is arranged between the locking seat 3 and the base 1. A first through groove 5 and a second through groove 6 are arranged on the locking seat 3. An unlocking piece 7 inserted into the first through groove 5 and a reset piece 8 inserted into the second through groove 6 are vertically slidably arranged on the base 1. An unlocking groove 9 for unlocking in cooperation with the first through groove 5 is arranged at the front end of the unlocking piece 7, and a reset inclined surface 10 for resetting in cooperation with the second through groove 6 is arranged at the front end of the reset piece 8. Second driving mechanisms for driving them to move upward are respectively arranged between the unlocking piece 7, the reset piece 8 and the base 1.

[0024] The locking principle of this embodiment is: in the locking state (as shown in the attached Figure 2 figure), the front end of the unlocking piece 7 abuts against the front end of the first through groove 5 to form a limiting structure, restricting the locking seat 3 from moving backward to form a locking structure; when unlocking is required, press the unlocking piece 7 downward to make it move downward. When the unlocking groove 9 moves to the position corresponding to the first through groove 5, the abutting structure between the unlocking piece 7 and the first through groove 5 is released. Driven by the first driving mechanism, the locking seat 3 moves backward along the unlocking groove 9, and the locking protrusion 4 moves backward accordingly to release the locking state of the knife plate 2 (as shown in the attached Figure 3As shown in the figure, in the unlocked state, the unlocking groove 9 and the bottom of the locking seat 3 form a hooked connection structure, and the second driving mechanism cannot drive the unlocking piece 7 to reset, so that the unlocked state is in a stable state; when it is necessary to re-lock the knife plate 2, press the reset piece 8 downward to move it downward, and the reset inclined surface 10 acts on the front end of the second through groove 6 to drive the locking seat 3 to move forward. When the locking seat 3 moves forward to the locking position, the first through groove 5 disengages from the unlocking groove 9, and the hooked connection structure between the unlocking groove 9 and the locking seat 3 is released. The second driving mechanism drives the unlocking piece 7 and the reset piece 8 to move upward respectively, and the locking seat 3, the unlocking piece 7 and the reset piece 8 are reset accordingly, and re-enter the locked state.

[0025] To facilitate the disassembly of the knife plate 2, a knife plate disassembly groove 11 is provided in the middle of the base 1. To obtain a more stable locking structure, two locking protrusions 4 are provided and symmetrically distributed on both sides of the knife plate disassembly groove 11. A through groove structure corresponding to the locking protrusions 4 is provided on the base 1. When locking, the locking protrusions 4 pass through the through groove structure and are inserted into the locking grooves of the knife plate 2.

[0026] In this embodiment, the sliding structure of the locking seat 3 is that a locking seat installation groove 12 is provided in the base 1, a pair of sliding rails 13 are provided in the locking seat installation groove 12, both sides of the locking seat 3 are respectively assembled on the sliding rails 13, and limiting blocks 14 are provided on the sliding rails 13. The bottom, front and rear end faces of the limiting blocks 14 respectively form a limiting structure for the locking seat 3; further, sliding groove structures for cooperating with the sliding rails 13 are respectively provided on both sides of the locking seat 3, and the limiting blocks 14 cooperate with the sliding groove structures for limiting. The bottom of the limiting block 14 forms a limiting structure for the downward movement of the locking seat 3 to prevent it from coming out, and the front and rear end faces of the limiting block 14 form a limiting structure for the front and rear movement of the locking seat 3 to prevent its excessive movement.

[0027] In this embodiment, the first driving mechanism is a first spring, and both ends of the first spring are respectively in contact with the base 1 and the locking seat 3 and are in a compressed state; further, first spring mounting seats are oppositely provided on the base 1 and the locking seat 3, and both ends of the first spring are respectively sleeved on the first spring mounting seats.

[0028] To facilitate the operation of moving the unlocking piece 7 and the reset piece 8 downward, an unlocking button 15 is provided at the upper end of the unlocking piece 7, a reset button 16 is provided at the upper end of the reset piece 8, an unlocking mounting groove 17 for accommodating the unlocking button 15 and a reset mounting groove 18 for accommodating the reset button 16 are provided on the base 1. A through hole for the unlocking piece 7 to pass through is provided at the bottom of the unlocking mounting groove 17, and a through hole for the reset piece 8 to pass through is provided at the bottom of the reset mounting groove 18.

[0029] In this embodiment, the second driving mechanism includes: a stud 19 disposed below the unlocking button 15 or the reset button 16 and a second spring sleeved on the stud 19. The upper end of the second spring abuts against the bottom of the unlocking button 15 or the reset button 16, and the lower end abuts against the bottom of the unlocking mounting groove 17 or the reset mounting groove 18. A guiding hole 20 for the stud 19 to pass through is provided on the unlocking mounting groove 17 or the reset mounting groove 18. A limit screw with a radial dimension larger than the guiding hole 20 is screwed to the bottom of the stud 19.

[0030] Compare with the attached Figure 5 Preferably, the unlocking piece 7, the unlocking button 15 and their corresponding studs 19 are integrally formed, and the reset piece 8, the reset button 16 and their corresponding studs 19 are integrally formed.
