Abstract

The utility model discloses a buckle type filter element which comprises a filter element body, an annular connecting disk and a sealing ring, wherein the annular connecting disk is fixedly connected to the filter element body and the sealing ring is connected to the connecting disk. At least three dummy clubs are respectively and uniformly arranged on the circumferences of the inner circle and the outer circle of the connecting disk, and the dummy clubs of the inner circle and dummy clubs of the outer circle are arrayed in an interlaced mode. The buckle type filter element is also provided with an annular clamping chuck, at least three inverted L-shaped buckles respectively extend and are uniformly distributed on the circumferences of inner circle and the outer circle of the annular clamping chuck along the axial direction. The positions of the buckles of the annular clamping chuck are corresponding to the positions of the dummy clubs of the connecting disk so as to make the buckles buckle the dummy clubs. The buckles and the dummy clubs are correspondingly buckled, the rapid and convenient connection is realized and the sealing performance is good. The utility model can be used as a filter unit of various machines.

Description

Clamping cartridge

[technical field]

The utility model relates to filter, especially relates to a kind of clamping cartridge.

[background technology]

Filter core is multiple installations filters commonly used, and existing filter core generally is that terminal pad and sealing ring are set on the filter core body, is connected in machine by thread connecting mode then, and this mode is installed inconvenience, and sealing property is bad.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of clamping cartridge, connects quick and convenient and good seal performance.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of clamping cartridge is provided, comprise the filter core body, be fixedly connected on the filter core body ring-like terminal pad, be connected in the sealing ring of terminal pad, the lug that has at least three circumference uniform distributions on the interior circle of described terminal pad and the cylindrical respectively, interior boss ear and cylindrical lug are staggered; Described clamping cartridge also has a ring-like chuck, prolongs the inverted "L" shaped buckle that axially stretches out at least three circumference uniform distributions respectively on the interior circle of this ring-like chuck and the cylindrical; The position of the buckle of ring-like chuck is corresponding with the lug position of terminal pad, so that each buckle and each lug fasten.

Further improvement in the technical proposal is:

Described lug and buckle are six circumference uniform distributions.

Described lug and buckle are five circumference uniform distributions.

Described terminal pad is made of plastics.

Described ring-like chuck and buckle are one, and are made by metal material.

The beneficial effects of the utility model are: because the utility model adopts buckle and ledge arrangement, with buckle and the corresponding fastening of lug, can realize quick, the convenient connection, ring-like chuck and terminal pad compress sealing ring, have guaranteed sealing effectiveness.

[specific embodiment]

Embodiment one

See also Fig. 1 to Fig. 4, a kind of embodiment for a kind of clamping cartridge of the utility model, on filter core body 1, connect a terminal pad 2, connect a sealing ring 3 on the terminal pad 2, the lug (4,5) that has six circumference uniform distributions on the interior circle of terminal pad 2 and the cylindrical respectively, interior boss ear 4 is staggered with cylindrical lug 5; Prolong the inverted "L" shaped buckle (7,8) that axially stretches out six circumference uniform distributions respectively on the interior circle of ring-like chuck 6 and the cylindrical, the buckle direction of interior round buckle 7 is the axle center dorsad, and the buckle direction of cylindrical buckle 8 is towards the axle center; Lug (4, the 5) position of the position of the buckle of ring-like chuck (7,8) and terminal pad is corresponding, so that each buckle and each lug fasten.Ring-like chuck 6 and terminal pad 2 are buckled together by the gap between buckle and between lug, compress sealing ring 3, rotation filter core body 1, each buckle and each lug can fasten, and can realize installing fast, easily filter core like this.Ring-like chuck 6 can be connected with machine by variety of way.

Embodiment two

See also Fig. 5 to Fig. 8, be the another kind of embodiment of a kind of clamping cartridge of the utility model, in this embodiment, the quantity of buckle and lug respectively is five, and all the other and fact Example one are identical, repeat no more.

Need to prove, the quantity of buckle and lug can be set according to the size and the concrete needs of filter core, circumference uniform distribution can achieve the goal so long as (comprise three) more than three, the purpose of three above circumference uniform distributions is to make strength even, the realization that how much does not influence this buckle structure of its quantity.

Claims

1, a kind of clamping cartridge, comprise the filter core body, be fixedly connected on the filter core body ring-like terminal pad, be connected in the sealing ring of terminal pad, it is characterized in that: have the lug of at least three circumference uniform distributions on the interior circle of described terminal pad and the cylindrical respectively, interior boss ear and cylindrical lug are staggered; Described clamping cartridge also has a ring-like chuck, prolongs the inverted "L" shaped buckle that axially stretches out at least three circumference uniform distributions respectively on the interior circle of this ring-like chuck and the cylindrical; The position of the buckle of ring-like chuck is corresponding with the lug position of terminal pad, so that each buckle and each lug fasten.

2, clamping cartridge as claimed in claim 1 is characterized in that: described lug and buckle are six circumference uniform distributions.

3, clamping cartridge as claimed in claim 1 is characterized in that: described lug and buckle are five circumference uniform distributions.
