DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trap, and more particularly to a so-called drum trap that is connected to a drain pipe of a laboratory sink or the like.

Conventionally, there is a trap of this kind as shown in FIG.

In this trap, a large number of bolts 40 are inserted from the opening periphery 9' of the trap body A', which is formed into a substantially bottomed cylindrical shape, to the lid B' placed on the periphery 9'.
By screwing the wing nuts 41 onto these bolts 40 from above the lid B and tightening them, both
A′ and B′ were installed and fixed.

Therefore, when cleaning the inside of the trap body A', remove the wing nuts 41 from the numerous bolts 40, remove the lid B, and after cleaning, reinstall the lid B into the trap body.
It had to be placed on A' and the wing nut 41 had to be screwed on, which had the disadvantage that the work was troublesome.

The present invention aims to eliminate the above-mentioned drawbacks and to make it possible to easily attach and detach the lid.

The basic structure of the present invention is that one end of the lever is rotatably mounted vertically on a support that is horizontally rotatably attached to one ear of the main body, and the other end is attached to the other ear of the main body. By engaging the joint part and providing a pressing part to press the lid in the middle part,
This allows the lid to fit tightly against the main body.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, A is a trap main body, and the main body A is formed into a bottomed cylindrical shape with an open upper surface, and has a substantially square-shaped inlet 1 protruding from its lower outer peripheral surface, and is opposed to the inlet 1. An outflow port 2 is horizontally protruded from the upper outer circumferential surface of the side.

Each of the inflow port 1 and the outflow port 2 has a flange 3 projecting outwardly formed at its tip opening, and a drain pipe 4 is connected to the flange 3, but the connection method differs depending on the material of the drain pipe 4.

That is, when the drain pipe 4 is made of vinyl chloride, the vinyl chloride pipe is inserted into a cylindrical socket 6 having a flange portion 5 corresponding to the flange 3,
The flange 3 and the flange portion 5 of the socket 6 are connected with bolts 7 and wing nuts 8, and if the drain pipe 4 is made of lead, the socket 6 is removed and the tip of the lead pipe is expanded and installed.

A flange piece 9 projecting outward is integrally formed on the periphery of the opening of the main body A, and a lid B is placed on the upper surface of the flange piece 9 via a packing 10.

The gasket 10 is formed into an annular shape, and its inner periphery is engaged with an annular piece 11 having a square cross section that protrudes from the back surface of the lid B, and when the lid B is placed on it, the outer half of the gasket 10 is shaped like a ring. It is designed to be held between the outer peripheral part and the collar piece 9.

Therefore, the gasket 10 ensures reliable sealing, and the gasket 10 does not fall off from the back surface of the lid B.

Further, the collar piece 9 has two ears 13 and 14, respectively, located on a straight line passing through the center of the opening 12 of the main body A and projecting further outward.

These two ears 13 and 14 have through holes 15 and 16 that pass through them in the vertical direction, and one of the through holes 15 has a support 17 and the other through hole 16 has an engaging part 18. installed.

The support 17 is formed by bending a band-shaped metal plate into a square shape, and has a through hole 19 bored in the center of its horizontal part, and the through hole 19 is positioned above one of the through holes 15, and both of these 19 , 15 from above, and tighten and fix the mounting bolt 20 to the tip of this bolt 20 from below with a wing nut 21.

At this time, the mounting bolt 20 has a portion 22 that passes through the through hole 19 that has a slightly smaller diameter than the through hole 19 and a larger diameter than the through hole 15 located below, so that the support 17 can be attached to one side. It is rotatable in the horizontal direction with respect to the ear part 13.

The upper end of the upright portion of the support 17 is bent into a cylindrical shape, and a rivet 25 through which one end of the lever 24 is inserted is rotatably passed through the cylindrical portion 23.

Therefore, the lever 24 has one end connected to the support 1.
7 so that it can rotate freely in the vertical direction.

The lever 24 is made by bending a band-shaped metal plate into a cross-sectional shape with the lower surface open, and the side surface shape is formed into an arch shape with the middle part located upward, and the middle part has a screw hole 27'. A engraved screw member 27 is integrally provided, and a pressing portion 26, which will be described later, is screwed together so as to be able to move forward and backward in the vertical direction.

The pressing part 26 is provided with an adjustment knob 28 at the upper end and a rubber shock absorber 29 at the lower end.By rotating the adjustment knob 28, the shock absorber 29 moves forward and backward in the vertical direction, and its lower surface is used. In this state, it comes into contact with the center of the upper surface of the lid B.

In addition, a fastener 3 is attached to the side of the other end of the lever 24.
A rivet 31 for attaching 0 is rotatably penetrated through it.

The fastener 30 is formed by bending a metal plate into a cross-sectional shape so that the lower surface is open, and the rivet 31 is inserted into one side surface of the metal plate, and a wire rod is bent into a rectangular shape at the other end side surface. A hanging ring 32 is rotatably supported.

Further, at the other end of the fastener 30, the upper surface is extended and protruded and curved upward in an arc shape to form an operating portion 33, and the side surface is extended and projected downward by a predetermined width and bent inward to close the lower surface. do.

On the other hand, a through hole 16 opened in the other ear portion 14
The engaging portion 18 attached to the band-shaped receiving plate 1 has a locking protrusion 34 whose lower end is bent downward at right angles.
8a, and a screw shaft 18b integrally fixed to the center of the upper surface of the receiving plate 18a.
8b into the through hole 16 from below, and
It is fixed by tightening the tip of the screw shaft 18b with a nut 18c.

The suspension ring 32 of the fastener 30 is adapted to engage with the locking protrusion 34 of the receiving plate 18a when in use.

Thus, the lid B is placed on the collar piece 9 formed at the opening periphery of the trap main body A via the gasket 10, and the pressing part 26 provided at the middle part of the lever 24 is pressed against the center part of the upper surface of the lid B. The lever 24 is rotated horizontally via the support 17 so as to come into contact with the lever 24, and the tip of the hanging ring 32 of the fastener 30 is engaged with the locking protrusion 34 of the engaging portion 18. When the operating part 33 of the fastener 30 is moved inward, that is, toward the pressing part 26, and the inner end of the closing part 35 formed on the lower surface of the fastener 30 comes into contact with the upper surface of the lever 24, the suspension ring 32 is closed. Cardinal branch 3
6 is a line connecting the tip of the hanging ring 32 engaged with the locking protrusion 34 and the rivet 31 that pivotally supports the fastener 30, and the fastener 30 is temporarily fixed beyond the so-called dead center.

At this time, the buffer body 29 provided at the lower end of the pressing part 26
The lower surface contacts the center of the upper surface of the lid B and presses it toward the main body A, but the adjustment knob 28 provided at the upper end of the pressing part 26 is rotated so that the buffer body 29 presses the lid B with appropriate pressure. Adjust.

Conversely, from this state, the operating section 3 of the tightening tool 30
When the lever 3 is moved outward, the engagement between the tip of the hanging ring 32 and the locking protrusion 34 is disengaged, and after moving the tip of the hanging ring 32 outward, the lever 24 is simply moved upward or horizontally. Lid B can be removed from main body A.

In addition, numeral 37 in the figure is a perforated plate that is detachably attached to the inside of the main body A.

Since the present invention has the above configuration, it has the following advantages.

Attach one end of the lever to a support attached to one ear of the main body so that it can rotate freely in the vertical direction, engage the other end of the lever with the engaging part of the other ear of the main body, and then Since the pressing part presses the top surface of the lid, when removing the lid, you can disengage the lever and move the lever upward to remove the lid.Also, when installing the lid, the lever can be removed. All you have to do is engage the other end with the engagement part of the ear part,
The work is extremely easy with just one touch, and the support that supports the lever is attached to one ear of the main unit so that it can rotate freely in the horizontal direction, so it can be used in places where there is no room to move the lever up. Even if the lid is attached, the lever can be rotated horizontally, so the lever does not get in the way when attaching or removing the lid.
