Detailed Description

The utility model is further described with reference to the following figures and embodiments.

First embodiment

Please refer to fig. 1, fig. 2, fig. 3, and fig. 4 in combination, wherein fig. 1 is a schematic structural diagram of a loop filter according to a first embodiment of the present invention; FIG. 2 is a schematic top view of the connector shown in FIG. 1;

FIG. 3 is a perspective view of the connector shown in FIG. 2; fig. 4 is a cross-sectional view of the connector of fig. 2. A loop filter comprising:

a base 1;

the connecting piece 2 is fixed on the top of the base 1;

the U-shaped groove 3 is formed in the connecting piece 2;

the mounting groove 4 is formed in the connecting piece 2, a clamping block 5 is connected between two sides of the inside of the mounting groove 4 in a sliding mode, and one side of the clamping block 5 penetrates through the mounting groove 4 and extends to the outside of the mounting groove 4;

the elastic piece 6 is arranged on the clamping block 5, and one side of the elastic piece 6 is arranged on one side inside the mounting groove 4;

in this embodiment, the elastic member 6 is a spring. It is understood that in other embodiments, the elastic member 6 may be other elastic members, such as elastic rubber and disc-shaped elastic pieces;

the elastic component 6 that sets up promotes joint piece 5 and slides at the in-process that kick-backs to carry out spacing fixed to loop filter 7.

The connecting piece 2 is provided with an annular filter 7, and the clamping block 5 is in contact with the outer surface of the annular filter 7.

One side of the clamping block 5 is provided with an arc surface 8 for the annular filter 7 to enter the U-shaped groove 3, and the bottom of the base is provided with a pin 9;

the annular filter 7 can conveniently slide into the mounting groove 4 for fixing through the arranged cambered surface 8.

The working principle of the annular filter provided by the utility model is as follows:

the first step is as follows: when the annular filter 7 is installed, the annular filter 7 is extruded into the connecting piece 2 to drive the clamping block 5 to move, so that the elastic piece 6 is compressed until the annular filter 7 completely enters the U-shaped groove 3, the clamping block 5 is pushed to move under the resilience of the elastic piece 6, the annular filter 7 is limited and fixed, and the installation of the annular filter 7 is completed;

the second step is that: when the annular filter 7 needs to be disassembled and maintained, the clamping block 5 is extruded by pulling the annular filter 7 to slide into the mounting groove 4, so that the elastic piece 6 is compressed and deformed, and then the annular filter 7 is pulled continuously until the annular filter 7 is completely separated from the mounting groove 4, so that the annular filter 7 is disassembled.

through the joint piece 5 and the elastic component 6 that set up, can carry out the joint to loop filter 6 and fix for easy operation, convenient to use, and through the mode that replaces the screw fixation, thereby avoided when dismouting loop filter 6, because the screw revolves the revolving opening part wearing and tearing too big, increase the degree of difficulty of dismouting, thereby improved this loop filter 6's practicality.

Second embodiment
