Description

Technical Field

[0001] The utility model relates to a metal filter bottle cover, in particular to a metal filter bottle cover sealing structure. Background Art

[0002] At present, in the prior art, metal filter bottles are widely used as filters in catering kitchens and factories. They include a metal filter bottle body, a metal filter bottle cover, a filter element and a seal, etc. The filter element is sealed in the metal filter bottle body through the metal filter bottle cover; the metal material used for its main body is mainly stainless steel. The metal filter bottle cover is generally a flange structure, and its sealing is mainly fastened by the bracket and multiple screws inside the metal filter bottle cover. This structure has the following defects: replacing the filter element requires removing multiple screws, which can easily cause the internal liquid to pour out and pollute the ground or the surrounding environment; and the speed of replacing the filter element or filter material is relatively slow, and the operation safety is also poor. Utility Model Content

[0003] In order to solve the above-mentioned defects of the existing metal filter bottle cover sealing structure, the utility model provides a metal filter bottle cover sealing structure with better disassembly and assembly performance and quick assembly and disassembly.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The inner cavity of the filter bottle can be completely covered on the boss column of the filter bottle cover. The filter bottle cover can be completely covered on the flanged platform of the filter bottle mouth. When the clamp ring is tightened, the filter bottle, the filter bottle cover and the sealing ring can be sealed. The filter bottle can be opened by loosening the clamp ring. The filter bottle cover can be quickly assembled and disassembled.

[0007] Furthermore, the lower part of the boss column of the filter bottle cover extends into the inner cavity of the filter bottle through the outer flange of the filter bottle. The filter bottle cover can be completely sleeved on the outer flange of the filter bottle mouth. The bottle cover and the mouth of the filter bottle are mutually sleeved. The aperture fit is a clearance fit.

[0008] Furthermore, the edge of the filter bottle cover is provided with a folded edge bent downward, and a U-shaped inflection groove is formed between the folded edge and the boss column at the root of the boss column; the sealing ring is located in the inflection groove.

[0009] Furthermore, the outer wall of the filter bottle is provided with a fixing bracket for fixing the filter bottle.

[0010] Furthermore, an inner wall of the clamp ring is provided with an inwardly recessed clamp groove, and the outer flange platform of the filter bottle and the folded edge of the filter bottle cover are both contained in the clamp groove.

[0011] Furthermore, the clamp ring includes a clamp hinge part, a clamp locking part, and two half rings, namely a left clamp and a right clamp. The head and tail of the left clamp and the right clamp are horizontally hinged together through the clamp hinge part and the clamp locking part in sequence to form a closed loop that can be opened and closed.

[0012] Furthermore, a clamp hinge fork is provided at the tail end of the left clamp ring, and a clamp hinge ear is provided at the tail end of the right clamp ring. The clamp hinge ear extends into the clamp hinge fork, and the clamp hinge ear and the clamp hinge fork are movably hinged through a hinge shaft; the clamp hinge ear and the clamp hinge fork constitute a clamp hinge part.

[0013] Furthermore, a clamp hinge arm hinge fork is provided at the head end of the left clamp ring, and a clamp locking fork is provided at the head end of the right clamp ring. The tail end of the clamp hinge arm is hinged to the clamp hinge arm hinge fork through a hinge shaft; a clamp locking groove is provided on the outer side of the clamp locking fork, and a clamp hinge arm locking pin is provided on the middle part of the clamp hinge arm. The clamp hinge arm locking pin is perpendicular to the clamp hinge arm in the vertical direction, and the clamp hinge arm locking pin is tightly matched with the clamp locking groove on the outer side of the clamp locking fork; an operating hole for operating the clamp hinge arm is provided on the head of the clamp hinge arm.

[0014] Working principle: By operating the clamp hinge arm on the clamp ring to disengage from the clamp locking groove, the locking state between the filter bottle cover and the filter bottle can be quickly released, and the filter bottle cover can be directly removed from the filter bottle, which is convenient for quick replacement of the filter element or filter material. Since there is no operation such as screwing, the filter bottle will not be shaken, and the liquid inside will not pour out and pollute the ground or the surrounding environment. The above-mentioned various problems existing in the prior art are solved. By operating the clamp hinge arm on the clamp ring, the clamp hinge arm locking pin is stuck into the clamp locking groove, and the filter bottle cover and the sealing ring can be locked on the filter bottle.

[0015] As can be seen from the above, compared with the prior art, the utility model has the following advantages: scientific structure and reasonable design; the filter bottle cover can conveniently and quickly seal the filter bottle or conveniently and quickly remove the filter bottle cover from the filter bottle. The metal filter bottle cover sealing structure adopted in the utility model can maintain relative stability when the filter bottle cover is disassembled and assembled, avoiding liquid overflowing from the outside of the filter bottle, and ensuring quick and safe replacement of the filter element or filter material.
