Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a magnetically adsorbed construction type plumb bob. Background Art

[0002] The plumb bob is the most primitive tool for testing the verticality of an object, and it is also one of the tools still in use today. Nowadays, the plumb bob is mostly used on construction sites to visually test the verticality of masonry walls and objects.

[0003] During the use of the plumb bob body, the winding part needs to be placed at a high place, and the pull wire is straightened by the plumb bob. The winding part placed at a high place needs to be fixed. The current fixing method mostly uses objects to press it down. This method has certain safety risks. At the same time, it is very inconvenient when measuring in some places where it is inconvenient to place the winding part.

[0004] Therefore, it is urgent to design a construction-type plumb bob that is convenient to fix with magnetic absorption. Utility Model Content

[0005] In order to overcome the shortcoming that the plumb bob body is inconvenient to fix, the utility model aims to solve the technical problem of providing a magnetically adsorbed building plumb bob that is convenient to fix.

[0006] In order to solve the above technical problems, the utility model provides a magnetically adsorbed construction plumb bob, comprising a shell, a magnetic block, an insertion rod, a winding wheel, a pull rope, a rotating handle, a spiral spring, a fastening bolt and a plumb bob body, the upper side of the shell is connected to the magnetic block, the inner upper side of the shell is slidably connected to the insertion rod, the inner lower side of the shell is connected to the winding wheel, a pull rope is wound around the winding wheel, the rear side of the shell is rotatably connected to the turning handle, the turning handle passes through the shell and is connected to the middle part of the winding wheel, a spiral spring is connected between the shell and the winding wheel, the front side of the shell is provided with a fastening bolt through a thread, and the pull rope hook on the lower side of the shell is provided with the plumb bob body.

[0007] Preferably, a guide ring is further included, the lower side of the shell is connected to the guide ring, and the pull rope passes through the guide ring.

[0008] Preferably, a protective shell is also included, and the protective shell is provided on the pointed cone of the plumb bob.

[0009] Preferably, a circular hole is provided on the right side surface of the housing.

[0010] Preferably, the housing is square in shape, compact and portable. Beneficial Effects

[0011] 1. The utility model can be adsorbed on the iron block through the magnetic block on the shell, the cement wall can be nailed to the cement with external nails, the round hole on the shell can be hung on the nail, and the wooden wall can insert the plug rod into the wooden board, achieving the effect of safe and convenient fixing;

[0012] 2. The utility model uses a volute spring and a fastening bolt to pull the pull rope out while the internal volute spring accumulates force and deforms. When the pull rope is pulled to a required length, the fastening bolt is tightened to compress the winding wheel. When the line is reeled in, the pull rope is automatically reset when it is loosened, achieving a convenient and easy retraction effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0019] A magnetically adsorbed construction plumb bob, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a shell 1, a magnetic block 2, an insertion rod 3, a winding wheel 4, a pull rope 5, a rotating handle 6, a volute spring 7, a fastening bolt 8 and a plumb bob body 10. A round hole is provided on the right side of the shell 1. The shell 1 is square in shape, compact and portable. The upper side of the shell 1 is connected to the magnetic block 2, which is square. The inner upper side of the shell 1 is slidably connected to the insertion rod 3, and the insertion rod 3 is inserted into the wooden board by moving left and right. The inner lower side of the shell 1 is connected to the winding wheel 4, and the pulling rope 5 is wound around the winding wheel 4. The rear side of the shell 1 is rotatably connected to the turning handle 6, and the turning handle 6 is connected to the shell 1 by being hinged. The turning handle 6 passes through the shell 1 and is connected to the middle part of the winding wheel 4. A volute spring 7 is connected between the shell 1 and the winding wheel 4. The front side of the shell 1 is provided with a fastening bolt 8 through a thread, and the fastening bolt 8 is rotatably movable back and forth. The plumb bob body 10 is hooked on the pulling rope 5 on the lower side of the shell 1.

[0020] like Figure 2 As shown, a guide ring 9 is also included. The lower side of the housing 1 is connected to the guide ring 9, and the pull rope 5 passes through the guide ring 9.

[0021] like Figure 4 As shown, a protective shell 11 is also included, and the protective shell 11 is arranged on the pointed cone of the plumb bob.

[0022] Working principle: When using the plumb bob, if you want to check the verticality of an object, adsorb the magnetic block 2 on the shell 1 onto a metallic iron block, first loosen the fastening bolt 8, pull the plumb bob body 10 downwards and drive the winding wheel 4 to rotate to the right at the same time, turn the handle 6 to drive it to rotate to the right together, pull the plumb bob body 10 and the pull rope 5 out together, and at the same time, the internal volute spring 7 will also accumulate force and deform, pull to the required length, then tighten the fastening bolt 8 to compress the winding wheel 4, and during the winding process, tighten the fastening bolt 8. The fixing bolt 8 is loosened, the body of the plumb bob 10 is released, and the volute spring 7 that has accumulated force and deformed will automatically retract the pull rope 5 and reset it. At the same time, a part of the cement stuck on the pull rope 5 will be scraped off by the guide ring 9. If the outer shell 1 is fixed too high and the pull rope 5 is too long, there is a safety risk in automatic rewinding. The pull rope 5 can be retracted by turning the handle 6. If there is no metallic iron block on the wall but cement, an external nail can be nailed to the cement, and the round hole on the outer shell 1 can be hung on the nail. When the wall is a wooden board, insert the plug rod 3 into the board.
