Description

Technical Field

[0001] The utility model belongs to the technical field of air suction arms, and in particular relates to an air suction arm that is easy to adjust and use. Background Art

[0002] As the name suggests, the suction arm refers to the connecting arm used to fix the suction hood on the suction equipment. The suction arm is suitable for collecting the source emissions of welding smoke, waste gas, dust, oil mist, oil fume and other waste gases generated by various industries such as machinery, food, pharmaceuticals, chemicals, electronics and automobiles.

[0003] According to the authorization announcement number CN215613966U, a retractable suction arm for a welding fume purifier is known as a prior art. Although the patent has the advantages of being able to adjust the suction arm to make it suitable for various workplaces and being highly practical, the technical solution of the patent has the following defects in actual use: since the end of the dust suction pipe and the dust hood are fixedly connected, when the dust hood is damaged, it is difficult to disassemble, repair or replace it, which brings inconvenience to the use of the suction arm. For this reason, we propose a suction arm that is easy to adjust and use. Utility Model Content

[0004] The purpose of the utility model is to provide a suction arm that is easy to adjust and use, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air suction arm that is easy to adjust and use, comprising an air suction pipe, one end of the air suction pipe is fixedly connected to a flange, and the outside of the air suction pipe is fixedly sleeved with a mounting plate, one side of the mounting plate is fixedly connected to a bellows, the other end of the air suction pipe is externally sleeved with an air suction hood, the inside of the air suction hood is fixedly sleeved with a sealing ring, the other end of the air suction pipe is fixedly sleeved with a clamping plate, the inner side of the clamping plate is fixedly connected with a fixing spring, the bottom end of the fixing spring is fixedly connected with a fixing block, and the top of the clamping plate is threadedly sleeved with a fixing bolt.

[0006] As a preferred implementation, the air intake pipe is a hose, the internal thread of the flange is sleeved with bolts, and the material of the bellows is a metal material.

[0007] As a preferred implementation, the sealing ring is made of rubber material, and the sealing ring is movably sleeved on the outside of the other end of the intake pipe.

[0008] As a preferred implementation, the fixing block is in an arc shape, and the inner side of the fixing block is in close contact with the outer side of the suction hood.

[0009] As a preferred implementation manner, the bottom end of the fixing bolt contacts the middle portion of the top end of the fixing block, and the fixing bolt and the fixing spring are parallel to each other.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The suction arm, which is easy to adjust and use, can be convenient for installing and disassembling the suction hood during the use of the suction arm by providing the clamping plate, the fixing spring, the fixing block and the fixing bolt. When the suction hood is damaged, the suction hood can be quickly disassembled, repaired or replaced, thereby bringing convenience to the use of the suction arm.

[0012] The suction arm, which is easy to adjust for use, can adjust the angle of the suction hood according to the needs of use during the use of the suction arm by arranging the suction pipe, the mounting plate and the bellows, that is, the suction arm can be adjusted for use, thereby improving the practicality of the suction arm.

[0017] The utility model is further described below in conjunction with embodiments.

[0018] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] See also Figure 1 and Figure 2 The utility model provides an air suction arm that is easy to adjust and use, including an air suction pipe 1, one end of the air suction pipe 1 is fixedly connected with a flange 2, the air suction pipe 1 is a hose, the internal thread of the flange 2 is sleeved with bolts, the outside of the air suction pipe 1 is fixedly sleeved with a mounting plate 3, one side of the mounting plate 3 is fixedly connected with a bellows 4, the material of the bellows 4 is a metal material, and the other end of the air suction pipe 1 is sleeved with an air suction cover 5;

[0020] In the present embodiment, when force is applied to the bellows 4 made of metal material, it is bent and deformed, and the suction pipe 1 is also bent and deformed driven by the bellows 4. Since the bellows 4 made of metal material can be adjusted to any angle, and the bellows 4 made of metal material can be automatically fixed after bending due to the characteristics of its own metal material, that is, its position can be fixed after the angle of the suction arm is adjusted, thereby facilitating the adjustment of the suction arm.

[0021] See also Figure 2 and Figure 3 The inside of the air hood 5 is fixedly sleeved with a sealing ring 6, which is made of rubber material and is movably sleeved on the outside of the other end of the air intake pipe 1. The other end of the air intake pipe 1 is fixedly sleeved with a clamping plate 7, and the inner side of the clamping plate 7 is fixedly connected with a fixing spring 8, and the bottom end of the fixing spring 8 is fixedly connected with a fixing block 9, which is in the shape of an arc, and the inner side of the fixing block 9 is in close contact with the outside of the air hood 5. The top of the clamping plate 7 is threadedly sleeved with a fixing bolt 10, and the bottom end of the fixing bolt 10 is in contact with the middle part of the top of the fixing block 9, and the fixing bolt 10 and the fixing spring 8 are parallel to each other;

[0022] In this embodiment, when the air intake hood 5 needs to be disassembled, the fixing bolt 10 can be rotated to cause it to rotate and move, so that the fixing bolt 10 and the fixing block 9 are separated. At this time, the fixed spring 8 in the compressed state needs to restore the elastic deformation, which will drive the fixing block 9 to move, so that the fixing block 9 and the air intake hood 5 are separated, causing the air intake hood 5 and the air intake pipe 1 to loosen, and the air intake hood 5 is pulled out, so that the air intake pipe 1 and the sealing ring 6 are separated, thereby facilitating the disassembly, maintenance or replacement of the air intake hood 5.

[0023] In the above scheme, it should be noted that: the flange 2 is used to install and fix the suction arm, and the bellows 4 can bend and deform when force is applied to the bellows 4 due to the characteristics of its own metal material. When no force is applied to the bellows 4, the bellows 4 will not deform and can be automatically shaped. The bellows 4 is like the "desk lamp corrugated tube" in the prior art.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
