Description

Technical Field

[0001] The utility model relates to a manual cutting tool, in particular to a practical tool for cutting flexible gaskets. Background Art

[0002] At the construction sites of some industrial installation projects, there are often situations where the original flange flexible gaskets are damaged, missing, or the seal fails, or there are some temporary situations where flexible gaskets are needed. Generally, the problem is solved by manually cutting and making flexible gaskets (such as polytetrafluoroethylene plates).

[0003] Before manually shearing a flexible gasket, a ruler is typically used to draw the inner and outer arcs of the gasket according to its inner and outer diameters. Scissors are then used to cut along these arcs. However, due to the rigidity of the flexible gasket, shearing with scissors can be laborious and result in rough edges, leading to low cutting efficiency. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-3 As shown, a practical tool for cutting flexible gaskets includes the following three parts:

[0031] Part 1:

[0032] The guide member 1 is made of a hollow steel pipe and is provided with scale lines. A first nut 11 is welded to a port at one end.

[0033] Part II:

[0034] The sliding part 4 is formed by welding four third nuts, which has at least two sets of coaxial third nuts. Specifically:

[0035] One of the groups cooperates with the guide member 1;

[0036] One third nut in the other group is threadedly connected to the second bolt 6 , while another third nut is welded to the tapered member 41 .

[0037] Part III:

[0038] A first bolt 2 is used for plugging with the blade 3 , and a second nut 21 is threadedly connected to the first bolt 2 .

[0039] Specific composition:

[0040] The first bolt 2 is threadedly connected to the first nut 11, and then the second nut 21 is rotated to push the blade 3 and clamp it with the first nut 11, and gaskets 5 need to be pre-placed on the first bolt 2 on both sides of the blade 3.

[0041] Then adjust the position of the sliding portion 4 from the blade 3 according to the scale, and then lock it by the second bolt 6. When in use, the tapered member 41 is the axis and the blade 3 is the radius length, thereby performing quantitative cutting of the flexible gasket.

[0042] The gasket 5 can be made of rubber or metal, or any other material known to those skilled in the art.

[0043] As an embodiment further provided by the present invention, the gasket 5 has grooves 51 arranged in a circumferential array on one side thereof, and the grooves 51 are covered by an arched elastic sheet 52 provided on the gasket 5;

[0044] The gasket 5 and the arched elastic sheet 52 in the finished product are both coated with rubber outer layers.

[0045] Secondly, combined Figure 3 It can be seen that the arched elastic piece 52 is divided into a first connecting portion 521 and a second connecting portion 522 according to the structure, and the angle between the two connecting portions is 135°-145°;

[0046] The length of the first connecting portion 521 is twice the length of the second connecting portion 522;

[0047] The end of the second connection portion 522 is not connected to the gasket 5 .

[0048] Therefore, when the second nut 21 is rotated to push the blade 3 and clamp it with the first nut 11, the first connecting portion 521 and the second connecting portion 522 are forced into the groove 51 due to the extrusion force. As the second connecting portion 522 abuts against the groove 51, the angle between the first connecting portion 521 and the second connecting portion 522 increases due to the extrusion. This creates a damping force to prevent the blade 3 from rotating due to the force during the cutting process.

[0049] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
