Description

Technical Field

[0001] The utility model relates to the field of cooling pump flanges, in particular to a disassembly and theft-proof cooling pump flange. Background Art

[0002] A flange, also known as a flanged disc or flange, is a component used to connect shafts. It is typically used to connect pipe ends or connect equipment inlets and outlets. A flange connection consists of a flange, a gasket, and bolts. It is a removable connection structure with sealing properties. A cold pump flange specifically refers to a flange connection used on cold pump equipment.

[0003] Existing cooling pump flanges are usually connected by fasteners such as bolts. These fasteners are relatively easy to disassemble. At the same time, the cooling pump flanges do not have anti-theft functions, making it possible for criminals to easily disassemble the flanges with tools and steal the fluid in the cooling pump or pipeline. This not only causes certain losses, but also affects fluid transportation.

[0004] Therefore, it is necessary to invent a dismantling-proof theft-proof cold pump flange to solve the above problems. Utility Model Content

[0005] The present invention aims to provide an anti-tampering and theft-proof cold pump flange. The flange is constructed by sheathing two sets of first and second protective shells onto the outside of the cold pump flange. Screws are then inserted through mounting holes formed on the outside of the first and second protective shells. A nut is then sheathed onto one end of the screw using a tool. A special screwdriver is then inserted into a triangular hole formed in a screw head formed at one end of the screw. The triangular hole is then rotated so that the two sets of first and second protective shells are securely mounted onto the outside of the cold pump flange. Finally, the outer sleeve is clamped onto the screw head, thereby providing a protective and theft-proof flange. The outer surfaces of the screw head and the nut have a certain curve, making them difficult to disassemble with general tools. The triangular hole formed inside the screw head also requires special tools for disassembly. This solves the problem that the existing cold pump flanges proposed in the background art are usually connected by fasteners such as bolts, which are relatively easy to disassemble. At the same time, the cold pump flanges do not have an anti-tampering and theft function. This allows criminals to easily disassemble the flanges with tools and steal the fluid in the cold pump or pipeline, which not only causes certain losses but also affects the fluid transportation problem.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disassembly and theft-proof cold pump flange, comprising a cold pump flange;

[0007] The first protective shell and the second protective shell are sleeved on the outside of the cold pump flange for protection and anti-disassembly, and mounting holes are opened on both sides of the outer surfaces of the first protective shell and the second protective shell;

[0008] The anti-theft screw assembly is installed on both sides of the first protective shell and the second protective shell to prevent disassembly and theft.

[0009] Preferably, a sealing groove is provided inside the cold pump flange, a sealing member is provided inside the sealing groove, and bolts are passed through the cold pump flange on all sides.

[0010] Preferably, limiting blocks are fixedly connected to both sides of the lower portion of the first protective shell, and limiting grooves are provided on both side surfaces of the upper portion of the second protective shell, and the limiting blocks are L-shaped.

[0011] Preferably, two groups of the first protective shell and the second protective shell are provided, wherein one group of the first protective shell and the second protective shell have a plug fixedly connected to one side thereof, and the other group of the first protective shell and the second protective shell have a slot provided on one side surface thereof.

[0012] Preferably, the anti-theft screw assembly includes a screw rod, which passes through the inside of the mounting hole, one end of the screw rod is fixedly connected to a screw head, the inner surface of the screw head is provided with a triangular hole, the outside of the screw head is provided with a jacket, and one end of the screw rod is movably connected to a nut on the outside.

[0013] Preferably, the screw head and the nut are arranged in a curve, and the outer sleeve is movably connected to the screw head.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The arrangement of the cold pump flange, the first protective shell, the second protective shell and the anti-theft screw assembly not only plays a protective role, but also strengthens the anti-disassembly and theft function. The two sets of first protective shells and the second protective shells are put on the outside of the cold pump flange, and then the screws are used to penetrate the mounting holes opened on the outside of the first protective shells and the second protective shells. Then, the nut is put on one end of the screw by a tool, and then a special screwdriver is inserted into the triangular hole in the screw head at one end of the screw. Then, the triangular hole is rotated so that the two sets of first protective shells and the second protective shells are firmly installed on the outside of the cold pump flange. Finally, the outer shell is stuck on the outside of the screw head, thereby forming a protective anti-disassembly and theft function. The outer surface of the screw head and the nut has a certain curve, so that they cannot be disassembled by general tools. At the same time, the triangular hole setting inside the screw head can also only be disassembled using special tools.

[0016] 2. Through the arrangement of the first protective shell, the limit block, the second protective shell, the limit groove, the mounting hole, the plug block and the slot, it is convenient to assemble the first protective shell and the second protective shell. By inserting the bevel edge of the limit block under the first protective shell into the limit groove inside the second protective shell, when the two are attached together, move the first protective shell so that the first protective shell and the second protective shell are flush, thereby completing the assembly. Then, the plug block on one side of the first protective shell and the second protective shell is inserted into the slot opened on the surface of one side of the other set of the first protective shell and the second protective shell, thereby facilitating the docking and installation of the two.
