Description

Technical Field

[0001] The utility model belongs to the field of level instruments, and in particular relates to a level instrument with a mounting structure. Background Art

[0002] When the level meter is in use, it needs to be installed at the top opening of the tank body to measure the distance between the top of the object in the tank body and the top opening of the tank body. When installing the level meter, it is necessary to first fix the level meter on the flange, and then install the flange with the meter on the tank flange.

[0003] The patent application with announcement number CN215950036U discloses a new type of level meter installation structure, including: a connecting flange and an end cover threadedly connected to the bottom of the connecting flange, the connecting flange is made of metal, and the end cover is made of polytetrafluoroethylene; the middle position of the connecting flange is provided with a sealing hole, a first threaded hole, and a second threaded hole that are interconnected from top to bottom, the first threaded hole is used for threaded connection with the level meter, the second threaded hole is used for threaded connection with the end cover, and the sealing hole is used to accommodate the sealing gasket of the level meter; a sealing part is protruding from the bottom of the connecting flange, the end cover is tightly connected to the sealing part, and a plurality of connecting holes connected to the external flange bolts are also provided on the connecting flange, and the connecting holes are located on the periphery of the sealing part. The utility model can protect the level meter to improve the measurement accuracy.

[0004] However, the above technology has the following disadvantages when used:

[0005] The paragraph 0022 of the above-mentioned document describes that "the above-mentioned connecting flange is provided with a plurality of connecting holes connected with the external flange bolts evenly distributed around the circumference of its central axis, and the connecting holes are located on the outer periphery of the sealing part. During assembly, the level meter and the end cover are first threadedly connected to the first threaded hole and the second threaded hole of the connecting flange respectively, and then the assembled overall mounting structure is bolted to the external flange of the container to be measured, and the connecting bolts are passed through the connecting holes of the connecting flange and the corresponding holes on the external flange. The connected end cover is tightly clamped between the connecting flange and the external flange. The outer diameter of the end plate of this embodiment is consistent with the outer diameter of the sealing part, which can ensure that the end cover is evenly stressed and effectively prevent the end cover from being damaged during the connection process". Combined with the water manual attached Figure 1 It can be seen that the level meter needs to be threadedly fitted into the interior of the connecting flange through the first threaded hole. Since no protective structure is provided between the connecting flange and the level meter, the level meter is prone to wear during installation.

[0006] Therefore, a level meter with an installation structure is proposed to solve the above-mentioned drawbacks. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a level meter with an installation structure.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0010] A first annular plate is rotatably engaged with the inside of the first annular groove, a second annular groove is opened on the upper side of the first annular plate, a second annular plate is elastically and slidably engaged inside the second annular groove, a plurality of hemispheres are evenly installed on one end of the second annular plate, and the hemispheres are engaged with one side of the level meter body.

[0011] Optionally, a first threaded hole and a second threaded hole connected to the first threaded hole are formed on one side of the flange, and a first external thread is formed on the outer wall at one end of the level instrument body, and the first external thread is threadedly matched with the first threaded hole; a second external thread is formed on the outer wall at one end of the end cover, and the second external thread is threadedly matched with the second threaded hole, so that the outer wall at one end of the end cover is threadedly matched with the inside of the flange through the second external thread and the second threaded hole.

[0012] Optionally, an annular sealing gasket is installed at the bottom of the flange to facilitate placing the annular sealing gasket at the bottom of the flange, and the annular sealing gasket is sleeved on the circumferential side of the end cover. The cross-sections of the first annular plate and the first annular groove are both L-shaped, and a spring is installed between the side wall of the second annular groove and one side of the second annular plate to facilitate installing the spring between the side wall of the second annular groove and one side of the second annular plate. A plurality of connecting holes are evenly distributed on one side of the flange.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] The hemisphere is provided to reduce the contact area between the hemisphere and one side of the level instrument body, so that the hemisphere drives the second annular plate to slide in and out of the second annular groove under the action of the level instrument body, making the process of disassembling and assembling the level instrument body more convenient and reducing the problem of wear of the level instrument body during installation.
