2. A filter cartridge guard according to claim 1 wherein: the pressing plate is arc-shaped.

Technical Field

The invention relates to the field of filtration, in particular to a protection device for a filter element.

Background

The filter element is a term of filtering and purifying function, and is mainly used in the filtering industries of oil filtration, air filtration, water filtration and the like at present in order to purify the resources of the original fluid and a simple and convenient device for separating the resources. The material of filter core has paper filter core, chemical fibre filter core or stainless steel net filter core etc. and its surface hardness of filter core of above-mentioned material is all not high, is squeezed the deformation easily in the transportation to make whole filter core can be useless.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a protection device for a filter element.

The invention is realized by the following technical scheme: the utility model provides a protector of filter core, includes the filter core, the outside parcel of filter core has the guard ring board, the guard ring inboard wall is close to upper end department and is fixed with the ring that stretches out, be equipped with the external screw thread on the outer wall of ring, the guard ring inboard wall is close to lower extreme department and is equipped with the internal thread, two symmetrical screw holes are seted up to the guard ring board, and screw hole female connection has the screw rod, and the screw rod is located the inside one end of guard ring board and is fixed with the clamp plate, and the screw rod is located the outside one end of guard ring board and is fixed with the round handle.

Further, the pressing plate is arc-shaped.

The invention has the beneficial effects that: when the protection is carried out to needs like this, at first cover the outside at the filter core with the guard ring board, the rethread rotates the round handle and makes the clamp plate be close to the filter core, can slightly push down the filter core through two symmetrical clamp plates, can prevent like this that the filter core from dropping, the guard ring board through the filter core outside plays the effect of a protection like this, can not press the surface of bad or extrusion filter core like this, and when meetting the longer filter core of length, can increase a guard ring board through the internal thread threaded connection of external screw thread on the ring and guard ring inboard wall this moment, can increase holistic length like this, with this can be according to the convenient holistic length that changes of the difference of filter core length, the use is facilitated.

in the figure: 1. a filter element; 2. a guard ring plate; 3. a circular ring; 4. a screw; 5. pressing a plate; 6. a round handle.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the novel filter element comprises a filter element 1, a protective ring plate 2 wraps the outside of the filter element 1, a stretched ring 3 is fixed on the inner wall of the protective ring plate 2 close to the upper end, external threads are arranged on the outer wall of the ring 3, internal threads are arranged on the inner wall of the protective ring plate 2 close to the lower end, two symmetrical threaded holes are formed in the protective ring plate 2, threaded holes are connected with screw rods 4 in an internal thread mode, a pressing plate 5 is fixed at one end, located inside the protective ring plate 2, of each screw rod 4, and a round handle 6 is fixed at one end, located outside the protective ring plate 2, of each screw rod 4. The pressing plate 5 is arc-shaped. Thus, the surface of the filter element 1 can be closer to the surface of the filter element, so that the fixing effect is better.

The invention has the beneficial effects that: when the protection is carried out to needs like this, at first cover the outside at filter core 1 with guard ring board 2, rethread rotates round handle 6 and makes clamp plate 5 be close to filter core 1, can slightly push down filter core 1 through two symmetrical clamp plates 5, can prevent like this that filter core 1 from dropping, the guard ring board 2 through filter core 1 outside plays the effect of a protection like this, can not press bad or extrude the surface of filter core 1 like this, and when meetting the longer filter core 1 of length, can increase a guard ring board 2 through the internal thread threaded connection of the external screw thread on ring 3 and the 2 inner walls of guard ring board, can increase holistic length like this, with this can conveniently change holistic length according to the difference of filter core 1 length, convenient use.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
