Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Example 1
Referring to fig. 1 to 4, the filter frame structure in this embodiment includes a square frame formed by four straight frames connected end to end in sequence, three fixed frames 1 connected end to end in sequence to form a whole in the four straight frames, and another movable frame 2 movably connected to the fixed frames 1; two ends of the movable frame 2 are provided with downward elastic connecting sheets 3, the lower ends of the elastic connecting sheets 3 are provided with arc-shaped clamping plates 31 protruding inwards, and the straight frame 1 is provided with clamping rings 6 for the arc-shaped clamping plates 31 to be inserted; when the arc clamping plate 31 is inserted into the clamping ring 6, the lower end of the arc clamping plate 31 is positioned on the outer side of the clamping ring 6 in the width direction, so that the movable frame 2 is fixed on the fixed frame 1.
The upper end of the elastic connecting piece 3 in this embodiment may be fixed to the movable frame 2 by welding, or may be fixed to the movable frame 2 by rivet fastening. It is of course also possible to form the flexible rim 2 integrally with the elastic web 3 during the injection moulding.
The elastic connecting piece 3 in this embodiment may be a metal elastic piece or a plastic elastic piece. The mode of inserting the elastic connecting sheet 3 into the clamping ring 6 replaces the original rivet to be connected and fixed, and the structure is simple and the installation is convenient.
The internal structure of the straight frame 1 is improved in the embodiment, two limiting plates 4 are arranged in the straight frame 1, and the limiting plates 4 are positioned on two sides of the snap ring 6. When the filter screen is used, a filter screen is inserted into the area limited by the limiting plates 4 and the side wall of the straight frame 1, and filter cotton is arranged in the area between the two limiting plates 4. The limiting plate 4 in this embodiment is detachable, and a vertical limiting clamping groove 11 is particularly arranged in the straight frame 1, and the limiting plate 4 is inserted into the limiting clamping groove 11. The limiting plate can be plugged and pulled in the straight frame, and the limiting plate is convenient to maintain and replace.
