Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a juicer for squeezing juice from vegetables, fruits, etc.

Conventional technology A conventional lever of this kind is, for example, the
As shown in Japanese Patent No. 25598, it has a structure as shown in FIG.

That is, a main body 3 on which a container 1 and a container lid 2 are placed.
By attaching a freely movable fixing plate 4 with one end pivoted to the outer surface of the container 1 and the container lid 2, the other end of the fixing plate 4 is hooked onto a protrusion 5 provided on the outside of the container lid 2. 2 was fixed to the main body 3.

Problems to be Solved by the Invention However, with such a structure, after placing the container 1 and the container lid 2 on the main body 3, the fixing plate 4 is rotated by an external force, and the protrusion 5 is attached to the fixing plate 4. Since the other end must be hooked, the operation of placing the container 1 and container lid 2 on the main body 3 and the fixing plate 4 are required.
Two operations are required, one for rotating the container, and the other is necessary to remove the fixed container lid 2 from the main body 3, which is very troublesome. Furthermore, since the fixing plate 4 protrudes significantly from the outer surface of the main body 3, it is difficult to make the entire product slim and compact.

In view of these problems, the present invention aims to automatically and easily attach and detach the container and the container lid to the main body, and to reduce the protrusion of the fixing plate from the main body, thereby making the product slim and compact. The purpose is to

Means for Solving the Problems In order to solve the above problems, the present invention has a structure in which a part projects from the side wall of the main body, and this projecting part fits into a locking part provided on the container lid, and is built into the main body. a clamp provided on the side wall of the main body of the clamp and whose lower side is inclined obliquely toward the inside of the main body; a spring that presses the clamp outward; The clamp includes an operating plate located below the inclined rib and moves up and down, and the angle of inclination of the lower part of the inclined rib of the clamp is reduced.

Effects According to the above configuration, when a container lid is attached after a container or the like is mounted on the main body, the container lid first hits the upper surface of the locking portion of the clamp that protrudes outside the main body. Thereafter, when downward pressure is applied to the container lid, the lower surface of the container lid applies a force toward the inside of the main body to the locking portion of the clamp, so that the clamp, which had been biased outward by the spring, is displaced inward. By further pressing the container lid downward, when the locking part of the container lid reaches the position of the locking part of the clamp, the clamp is displaced outward by the spring, and the locking part of the clamp locks the container lid. The container lid is fixed to the main body. Next, when removing the container lid from the main body, operate the operating plate, which partially protrudes outside the main body, from the outside.The operating plate moves upward within the main body as if pushing against the slanted ribs of the clamp, so that the clamp can be removed from the main body. By moving inward, the locking part of the container lid is released from the clamp, allowing the container etc. to be removed from the main body.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 10. In the figure, 11 is a motor attached to the lower part of the main body 12 via a buffer 13 with screws 14, 15 is an output shaft connected to the rotating shaft of the motor 11, and a substantially cylindrical centrifugal shaft is attached to the upper end of the output shaft. A basket 16 is detachably attached.
17 is a substantially cylindrical comb-shaped filter that is detachably attached to the inside of the centrifugal separation cage 16; 18 is a cutter provided at the center bottom of the centrifugal separation cage 16; 19;
is a youth receiving container placed on the main body 12,
A juicer outlet 20 is provided in a part of the lower part. Reference numeral 21 denotes a leaf spring attached to the lower surface of the youth container 19, and this leaf spring 21 is pressed by a protrusion 22 when the youth container 19 is attached to the main body 12. Reference numeral 23 denotes a container lid that is removably fitted to the juice receiving container 19, and the container lid 23 has a material input port 24 in its center. 25 is a push rod inserted into the material input port 24 to press vegetables, fruits, etc. onto the cutter 18; 26 is a bottom plate that covers the lower surface of the main body 12 and has legs 27 attached thereto. 2
Reference numeral 8 denotes a plate-shaped clamp whose lower end is supported by a fixing portion 29 provided at the inner bottom of the main body 12, and the upper part of which is always urged toward the outside of the main body 12 by a spring 30. Further, at the upper end of this clamp 28, a locking part 31 with an inclined upper surface is provided so as to protrude outward from the main body 12, and below the locking part 31, an inclined rib 32 whose lower side is inclined inward is provided inside the main body 12. . 33 is a shaft holding the operating plate 34, and a screw 35
It is fixed to the main body 12 by. The operating plate 34 freely rotates around the shaft 33, and a knob 36 protruding from the main body 12 is attached to one side of the operating plate 34.
The other end is located below the inclined rib 32 of the clamp 28. Reference numeral 37 denotes an operating leaf spring that presses the operating plate 34 downward. 3
Reference numeral 8 denotes a lid extension extending downward from the container lid 23, and the lid extension 38 is provided with a hole 39 that fits into the locking part 31 of the clamp 28.

The operation of the above configuration will be explained next.
First, after attaching the container 19 and the centrifugal cage 16 to the main body 12, the container lid 23 is attached, and the lid extension 3
The lower end of the clamp 8 abuts against the locking portion 31 at the upper end of the clamp 28 . When the container lid 23 is further pressed downward,
As shown in FIG. 6, the clamp 28 pressed by the spring 30 receives an inward force of the main body 12 from the slope provided on the upper surface of the locking portion 31, so that the clamp 28 is displaced inward of the main body 12. By further pressing the container lid 23, when the hole 39 provided in the lid extension 38 reaches the position of the locking part 31 of the clamp 28, the locking part 31 is moved to the hole 3 by the force of the spring 30.
9 and the clamp 28 is restored. As a result, the container lid 23 is fixed to the main body 12 as shown in FIG. That is, the container lid 23 can be fixed to the main body 12 with a single operation of attaching the container lid 23 to the main body 12 and pressing it downward.
At this time, the leaf spring 2 attached to the bottom surface of the container 19
1 is pressed by a protrusion 22 on the main body 12.

Next, when separating the container lid 23 from the main body 12, press the knob 36 downward with your finger.
Since the operating plate 34 rotates about the shaft 33, the portion of the clamp 28 of the operating plate 34 located below the inclined rib 32 is displaced upward, and the clamp 28 is moved to the height of the inclined rib 32 as shown in FIG. The locking part 31 of the clamp 28 is pushed inward by a certain amount, and the locking part 31 of the clamp 28 is pushed inward by the lid extension part 3.
It comes off through the hole 39 provided at 8. Then, the leaf spring 21 attached to the lower surface of the container 19 and pressed by the protrusion 22 of the main body 12 causes the container 19 and the container lid 23 to rise, so that even if the finger pressing the knob 36 is released, Since the locking portion 31 of the clamp 28 does not fit into the hole 39 of the lid extension 38, the container lid 23 can be separated from the main body 12 by lifting the container 19 and the container lid 23.
Here, when the operating plate 34 moves the clamp 28 via the inclined rib 32, the operating force of the knob 36 will be
At the moment when the clamp 28 starts to move along the inclined rib 32, the static frictional force between the two becomes maximum, and it takes a great deal of force to operate the knob 36. However, as shown in FIG. When the inclination angle a is made smaller, the force with which the operating plate 34 displaces the clamp 28 inward becomes smaller, so that the clamp 28 can be moved inward with a slight operating force of the knob 36. Once the operating plate 34 starts to move, the frictional force between the inclined rib 32 and the operating plate 34 becomes smaller. Incidentally, instead of reducing the inclination angle a of the lower part 40 of the inclined rib 32, the same effect can be obtained by providing a radius (R) at the intersection of the lower part 40 and the clamp 28, as shown in FIG. 10b. That's what you get.

Furthermore, according to the configuration of the present invention, since the clamp 28 is built inside the main body 12 and the container lid 23 is fixed from the inside, the number of parts protruding to the outside of the main body 12 is reduced, and the size thereof is also reduced. This allows the entire product to be made more compact.
Moreover, product storage can be done in a space-saving manner.
Furthermore, since there is no clamp 28 on the outside of the main body 12, there is no chance of the clamp 28 getting caught on the user's clothes or the like and causing malfunction.

Effects of the Invention As is clear from the description of the embodiments above, the juicer of the present invention has a part that projects from the side wall of the main body, and this projecting part fits into the locking part provided on the container lid, and is built into the main body. a clamp provided on the side wall of the main body of the clamp and whose lower side is inclined obliquely toward the inside of the main body; a spring that presses the clamp outward; It is provided with an operating plate located below the inclined rib and moves up and down, and the inclination angle of the lower part of the inclined rib of the clamp is reduced.
The container lid can be fixed to the main body by simply pressing it downward while being mounted on the main body, and the container lid and the main body can be unfixed by simply pushing the operating plate downward from the outside of the main body. Moreover, not only can the entire product be made slim and compact, but since there are few irregularities on the outside of the main body, it has various excellent effects such as eliminating the possibility of getting caught.
