Description

[Detailed Description of the Invention] The present invention relates to a mulberry breeding stand that can be assembled efficiently.

Conventionally, in order to attach support pins for passing connecting rods in mulberry breeding stands, the pins were welded directly to the mounting member, or the pins were inserted into holes provided in the mounting member and welded. In either case, it was difficult to accurately plant the pin in an upright position, and even experienced workers were unable to improve work efficiency.

In order to improve such drawbacks, the present invention provides a flange on the support pin so that when the pin is inserted into a hole provided in the mounting member, the pin stands upright due to the flange, and the flange is attached to the mounting member. It can be easily welded vertically.

This will be explained below along with examples.

Although the support pin 1 shown in the figure is made of a round metal rod, it can also be made of a square rod or pipe material, or it can be made of a plastic material, and it is placed in a substantially horizontal position on the proximal end side. It has a flange 2.

The flange is made integrally with the pin by forging or injection molding, but it can also be fixed later.

Note that the length below the flange is the length of the hollow mounting member 3.
The length is such that the tip does not touch the inner wall 5 of the mounting member when it is inserted into the mounting hole 4 of the mounting member, and the outer diameter of the flange is shorter than this length (Fig. 1). reference).

Further, the shape of the flange can be any other suitable shape such as a triangle, a square, etc. in addition to a round shape.

When the tip of the support pin is inserted into the mounting hole, the flange contacts the periphery of the hole in the mounting member and stands up almost vertically.If the flange portion is welded, it can be easily installed in an upright position. Can be set.

Note that it may be bonded with an adhesive if desired.

FIG. 2 shows the mulberry breeding stand 6 with the support pins attached as described above, and the frame members 9 with the supports 8 attached on both sides of the leg rods 7 with the pins 1 implanted therein are attached as appropriate. Arranged in parallel at intervals, insert a connecting rod 10 with an insertion hole at the tip into the pin, place a net member 11, a silkworm seat sheet 12, etc. on the top surface of the connecting rod 10,
A side rod 13 is provided on the upper periphery and the silkworm seat is hung over the seat.

The present invention is constructed as described above, and since a flange is provided in the middle of the pin, by seating the flange on the upper surface of the leg rod, it can be fixed by welding etc. in the correct upright state. Since the flange does not reach the opposing inner wall of the leg lever, there is no fear that the flange will lift up when inserted into the mounting hole, and the pin that is inserted into the mounting hole will sit accurately on the leg lever. The outer diameter of the mounting hole and the pin are usually formed so that there is not much difference in outer diameter to prevent the pin from moving, so if you cannot see the tip of the pin when inserting it into the mounting hole, it will be difficult to insert it into the hole. Since the outer diameter of the flange is shorter than the length from the part where the flange is installed to the tip of the pin, the tip of the pin can be clearly seen from above when inserted into the mounting hole.
Therefore, it is easy to insert, and when welding, even if the tip of the welding rod is pressed against the flange or the leg rod swings, the tip of the pin goes deep into the mounting hole, making it easy to move. The welding work is easy, and the pins can be planted in an upright position without falling off. Therefore, when assembling the mulberry breeding stand by passing the connecting rod between the pins, There is no problem such as difficulty in engaging the insertion hole with the pin.

Claims (1)

[Scope of utility model registration request] A suitable number of mounting holes are drilled in the upper surface of the pipe leg rod, and a pin that can be inserted into the hole is provided, and the pin is supported in the middle of the pin so that the tip of the pin does not reach the inner wall of the leg rod. A flange is provided, the outer diameter of the flange is formed to be shorter than the length from the tip of the pin to the part where the flange is provided, the flange portion is fixed to a leg rod, and the leg rods are arranged in parallel at appropriate intervals to attach the pin. A mulberry breeding stand in which a connecting rod with insertion holes at both ends is inserted between the two, and a net member, a silkworm seat sheet, etc. are placed on the top surface to form a silkworm seat.
