Description

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

2. Description of the Related Art A conventional juicer of this kind is, for example, disclosed in Japanese Utility Model Publication No. 61-255.
As shown in Japanese Patent No. 98, the structure was as shown in FIG. 11.

That is, container 1. A fixed plate 4 whose one end is pivotally supported on the outer surface of the main body 3 on which the container lid 2 is placed and which moves freely? : Attachment, the other end of this fixing plate 4 is attached to a protrusion 5 provided on the outside of the container lid 2.
By hooking the container 1 and container lid 2 onto the main body 3
It was fixed at

Problems to be Solved by the Invention However, with such a structure, the container 1. After placing the container lid 2, the fixing plate 4 must be rotated by an external force and the other end of the fixing plate 4 must be hooked on the protrusion 5. Two operations are required: 1 and 2, rotating the fixing plate 4, and when removing the fixed container lid 2 etc. from the main body 3, the reverse operation is required, 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 allows containers and container lids to be automatically and easily attached to and removed from the main body, and to reduce the protrusion of the fixing plate from the main body, thereby making it possible to make the product slim and compact. The purpose is to

Means for Solving the Problems In order to solve the above-mentioned 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. 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 structure, when the container lid is attached after all the containers and the like are 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 moves to the locking part of 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. By moving inward, the engaging part of the container lid disengages from the clamp, allowing the container, etc., to be removed from the main body.

EXAMPLE Hereinafter, an example 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,
A substantially cylindrical centrifugal separator fi1s is detachably attached to its upper end.

Reference numeral 17 denotes a substantially cylindrical comb-shaped filter that is detachably attached to the inside of the centrifugal separator 16, 18 a cutter provided at the center bottom of the centrifuge 16, and 19 a juice receiver placed on the main body 12. is a container, and a juice outlet 20 is provided in a part of the lower part of the container. Reference numeral 21 denotes a leaf spring attached to the lower surface of the container 19. When the juice container 19 is attached to the main body 12, the leaf spring 21 is attached to a protrusion 22.
Pressed by Reference numeral 23 denotes a container lid which is detachably fitted onto the container 19, and the container lid 23 is provided with a material input port 24 in the center thereof. Reference numeral 25 represents a push rod that is inserted into the material input port 24 and presses vegetables, fruits, etc. onto the cutter 18, and 26 represents a bottom plate that covers the lower surface of the main body 12 and has legs 27 attached thereto.

Reference numeral 28 denotes a plate-shaped clamp whose lower end is supported by a fixing part 29 provided at the inner bottom of the main body 12, and whose upper part 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 portion 31 with an inclined upper surface is attached to the main body 12.
An inclined rib 32 is provided in the main body 12 so as to protrude outward, and further below the rib 32, the lower side thereof is inclined inward.

33 is a shaft holding the operating plate 34, and screw 3E? It is fixed to the main body 12 by. The operating plate 34 freely rotates about the shaft 33, and has a knob 36 protruding from the main body 12 attached to one end thereof, and the other end thereof is provided so as to be located at a lower portion of the inclined rib 32 of the clamp 28. ing.

Reference numeral 37 denotes an operating leaf spring that presses the operating plate 34 downward.

Reference numeral 38 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, when the container 19, the centrifuge box 16, etc. are attached to the main body 12, and then the container lid 23 is attached, the lower end of the lid extension 38 abuts against the locking portion 31 at the upper end of the clamp 28. When the container lid 23 is further pressed downward, the spring 3 is released as shown in FIG.
Since the clamp 28 pressed by
Clamp 28 is displaced inside 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 portion 31 is fitted into the hole 39 by the force of the spring 30, and the clamp 28 is restored to its original state. 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 21 attached to the lower surface of the container 19 is pressed by the 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, and the operating plate 34 will move from the shaft 3.
3 as a fulcrum, 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 inward by the height of the inclined rib 32, as shown in FIG. When pushed, the locking part 31 of the clamp 28 comes out of the hole 39 provided in the lid extension part 38. 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, the operating plate 34 is inserted into the clamp 2 via the inclined rib 32.
When moving the knob 8, if the angle of inclination of the inclined rib 32 is constant, the static friction force between the two becomes maximum at the moment when the operating plate 34 starts moving with the help of the inclined rib 32.
Although a large amount of force is required to operate the knob 36, as shown in FIG.
Since the force that displaces the knob inward becomes smaller, the knob 36
The clamp 28 can be moved inward with a slight operating force. Once the operating plate 34 starts moving, the inclined rib 32
The frictional force of the operating plate 34 becomes smaller. In addition, the inclined rib 3
Instead of reducing the inclination angle a=i of the lower part 40 of 2,
As shown in FIG. 10, the same effect can be obtained by providing a radius (R)' at the intersection of the lower portion 4o and the clamp 28.

Further, according to the configuration of the present invention, the clamp 28 is attached to the main body 12.
In order to fix the container lid 23 from the inside,
Since the number of parts protruding to the outside of the main body 12 is reduced and the size thereof can be reduced, the entire product can be made compact, and the product can be stored in less space.

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 protrudes from the side wall of the main body, and this protruding part fits into a locking part provided on the container lid, and the juicer 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 equipped with an operating plate located below the slanted rib and moves up and down, and the inclination angle of the lower part of the slanted rib of the clamp is made small, so that by simply pressing the container lid downward while attaching it to the main body, the main body can be moved. At the same time, 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 many excellent effects such as eliminating the possibility of getting caught.
