AI Technical Summary
The existing sanitary tank connectors have shortcomings in cleaning and disassembly. The clamp joints are prone to forming dead-angle fluid, the NA flange structure is complex and inconvenient to disassemble, and it is difficult to operate when installing functional metering instruments.
A sanitary tank clamping connection piece is designed, including a base, a press plate and a clamp. The clamping part of the base and a press plate is locked through the clamp to achieve a tight connection between the tank attachments, simplifying the structure and optimizing the internal structure of the flange for easy cleaning and quick disassembly and assembly.
It realizes simple installation of tank parts and is easy to clean, meets the residual-free needs of sanitary tanks, and the installation space and disassembly of functional metering instruments are more convenient.

Abstract
Description
Technical Field
[0001] The utility model relates to a connecting piece, in particular to a sanitary clamping connecting piece for a tank. Background Art
[0002] The commonly used existing sanitary connecting pieces for tanks are clamp joints and NA flanges, which are widely used in the field of pharmaceutical sanitary tanks. Their main function is to connect tank accessories (functional measuring instruments such as thermometers, pH meters, sampling valves, etc.) to ensure the hygiene and sterility of the connecting parts of the tank. The existing clamp joints (as shown in Figure 2 shown) are in a clamping form and are equipped with a short steel pipe. When assembling with the functional measuring instrument joint, gaskets and clamps are used to connect the two together; the NA flange (as shown in Figure 3 shown) uses a compression ring to fasten the functional instrument joint, the NA flange and the gasket together with stud bolts and cap nuts. Both of these joints have certain deficiencies: 1. The clamp joint is not easy to clean in the sanitary tank because of the short steel pipe, and it is easy to form dead corners and accumulate liquid at the lower head; 2. The NA flange has a complex structure, the compression ring is connected by stud bolts, which is not convenient to disassemble, and the space is limited, making it difficult to install for an injection type sampling valve. Therefore, developing a sanitary clamping connecting piece for a tank has become an urgent problem for those skilled in the art. Summary of the Utility Model
[0003] The utility model is to solve the above deficiencies and provides a sanitary clamping connecting piece for a tank, which can simultaneously meet the sanitary requirements of no residue at the bottom of the tank during the use process by users, and meet the quick disassembly and assembly requirements of users for functional measuring instruments.
[0004] The above object of the utility model is achieved by the following technical solutions: A sanitary clamping connecting piece for a tank includes a base, a pressing plate and a clamp. The base is provided with a base through hole, the bottom of the base through hole is provided with a supporting part, and the side wall of the base is provided with a V-shaped groove to form a base clamping part; the pressing plate is provided with a pressing cylinder part, and the edge of the upper end surface is provided with an outer slope surface to form a pressing plate clamping part; the pressing cylinder part of the pressing plate is sleeved in the base through hole and presses the connecting port of the tank accessory. A gasket is arranged between the connecting port of the tank accessory and the supporting part in the base through hole. The base clamping part and the pressing plate clamping part are locked by the clamp and press the connecting port of the tank accessory. When the clamp locks and squeezes the outer slope surface at the edge of the upper end surface of the pressing plate, the pressing cylinder part of the pressing plate can press the connecting port of the tank accessory tighter.
[0005] The advantages of the present utility model compared with the prior art are as follows: The present utility model adopts snap-on installation, featuring a simple appearance, a compact structure, convenient and quick installation, and easy cleaning. It can meet the requirements of a hygienic tank body for component connectors and is also applicable to the installation at the bottom of the tank. At the same time, the interior of the present utility model is similar to that of an NA flange, while optimizing the internal structure of the flange, reducing the liquid storage space inside the flange, and ensuring the installation space and the requirement for quick disassembly and assembly of external functional measuring instruments. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 is a schematic structural diagram of the present utility model.
[0007] Figure 2 is a schematic structural diagram of a prior art clamp joint (in the state of the top of the tank being installed upright).
[0008] Figure 3 is a schematic structural diagram of a prior art NA flange (in the state of the top of the tank being installed upright). DETAILED DESCRIPTION OF THE EMBODIMENTS
[0009] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0010] As Figure 1 shown, a snap-on connector for a hygienic tank includes a base 1, a pressing plate 2, and a clamp 3. The base 1 is provided with a base through-hole 101. At the bottom of the base through-hole 101, there is a supporting portion 102 that extends towards the center of the base through-hole 101 to form a circular support. On the side wall of the base 1, there is a V-shaped groove 103, forming a base snap-in portion 104. The base snap-in portion 104 is provided with an inclined surface 105 that facilitates the clamping of the clamp 3. The pressing plate 2 is provided with a pressing cylinder portion 201, and the edge of the upper end surface is provided with an outer inclined surface 202, forming a pressing plate snap-in portion 203. The diameter of the pressing plate snap-in portion 203 is equal to that of the base snap-in portion 104. The pressing cylinder portion 201 of the pressing plate 2 is sleeved in the base through-hole 101 and presses tightly against the connection port 5 of the tank accessory. A gasket 4 is provided between the connection port 5 of the tank accessory and the supporting portion 102 in the base through-hole 101 to prevent leakage and ensure sealing. The base snap-in portion 104 and the pressing plate snap-in portion 203 are locked by the clamp 3 and press tightly against the connection port 5 of the tank accessory. When the clamp 3 locks and presses the outer inclined surface 202 at the edge of the upper end surface of the pressing plate 2, the pressing cylinder portion 201 of the pressing plate 2 can press the connection port 5 of the tank accessory more tightly.
[0011] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
