Technical Field

The utility model relates to an end cap technical field for lean pipe shelf especially relates to an end cap structure.

Background

The rectangular pipe plug applied to the lean pipe shelf mainly has the function of plugging two ends of a hollow rectangular pipe to prevent foreign matters from entering the hollow pipe body. The plug on the market is simple in structure, the size is designed according to the model of the rectangular pipe, and the function of plugging the opening basically can be achieved. However, after a long period of use, the size of the plug becomes incompatible with the opening of the tube due to expansion and contraction or loss of the material, and in this case, the plug needs to be replaced. Many people feel troublesome and can directly put the plug into the pipe body, and the plug slowly loses the function of blocking the opening, so that foreign matters can enter the pipe body. In view of the above, a plug structure capable of adjusting according to the size change of the tube body is needed.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; either directly or indirectly through intervening media, or may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Please refer to fig. 1 and 2: a plug structure comprises an outer block body 10, an inner block body 13 and four groups of adjusting structures, namely an adjusting structure 14, an adjusting structure 20, an adjusting structure 16 and an adjusting structure 15, wherein the inner block body 13 is connected with the outer block body 10, and the adjusting structure 14, the adjusting structure 20, the adjusting structure 16 and the adjusting structure 15 are correspondingly arranged on four sides of the inner block body 13 respectively; adjusting structure 14, adjusting structure 20, adjusting structure 16, adjusting structure 15 all include fixed block 17, adjusting bolt A26, spring 18, contact piece 19, and the fixed setting is including a lateral surface that block 13 kept away from outer block 10 including fixed block 17 is fixed, and adjusting bolt A26's one side is run through fixed block 17 and spring 18 fixed connection, and spring 18's opposite side and contact piece 19 are connected.

In this embodiment, in the end cap inserted the rectangular pipe body, the inner wall of rectangular pipe body is all hugged closely to each contact block under the effort of spring, thereby increase the connection effort of end cap and body, after the inner chamber size of rectangular pipe body changes, perhaps under the great condition of elastic force loss of spring, can drive the spring through adjusting bolt A and use the fixed block to stretch out the distance adjustment as the fulcrum, thereby adapt to new size, ensure that the end cap can continue to hug closely with the inner wall of rectangular pipe body, thereby promote life.

In a preferred embodiment, the outer block 10 is connected to the inner block 13 by an adjusting bolt B22, and the adjusting bolt B can be used to adjust the distance that the inner block extends into the rectangular tube.
