DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0020] The following describes a resonant filter provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0021] Combined with Figure 1-2 As shown, a resonant filter provided by the present utility model includes: a filter component 100 and an outer protection component 200; wherein, the filter component 100 includes a main body 110, connection heads 120 provided at both ends of the main body 110, and a connecting wire 130 connected to the connection heads 120.

[0022] Among them, the outer protection component 200 is arranged on the main body 110. The outer protection component 200 includes an outer sheath 210 sleeved on the outside of the main body 110, a cushion support frame 220 fixed on the inner side of the outer sheath 210, fixing openings 230 opened at both ends of the outer sheath 210 and located outside the connecting line 130, a fastening ring 240 sleeved on the outer sheath 210 and located outside the fixing openings 230, a binding band 250 fastened on the fastening ring 240, a fixing piece 260 fixed on the inner side of the fastening ring 240 and located in the fixing openings 230, and an anti-slip piece 270 arranged at the bottom of the fixing piece 260. Through the outer protection component 200, the outer sheath 210 can be used to protect the main body 110 on the outside, and the two ends of the outer sheath 210 can be fixed on the connecting line 130 by using the fastening ring 240, so that the main body 110 can be stably connected between the connecting lines 130, and the cushion support frame 220 is used to achieve a protective effect. Furthermore, when hanging, faults such as line loosening, vibration and collision damage can be avoided, greatly improving the safety of the filter during use. And it does not need to be installed, is suitable for various environments, and also improves the practicality of the filter.

[0023] Specifically, a fixing ring 211 is arranged inside the outer sheath 210 on the side of the connector 120, and a conical support frame 212 is connected to the fixing ring 211. The fixing ring 211 and the support frame 212 can play a supporting role to prevent the fastening ring 240 from sliding towards one side of the main body 110, and improve the stability of the outer sheath 210.

[0024] Furthermore, the cushion support frame 220 is an X-shaped mesh plate structure evenly distributed on the inner side of the outer sheath 210. The cushion support frame 220 can play a cushioning and buffering function, and at the same time does not affect the normal heat dissipation of the main body 110, which is relatively practical.

[0025] On the other hand, fixing thorns 213 are also arranged on the inner side of the outer sheath 210 between the fixing openings 230, which can make the fixing thorns 213 slightly prick and fix on the connecting line 130, playing a role in anti-slip and stability.

[0026] Furthermore, the anti-slip piece 270 is a crescent-shaped anti-slip pad structure. When the fastening ring 240 squeezes the fixing piece 260 inward, the anti-slip piece 270 can be squeezed and fixed on the connecting line 130. And the crescent-shaped structure has a small friction force in the un-squeezed state, which does not affect the adjustment of the position of the fastening ring 240, which is relatively reasonable.

[0027] It should be noted that heat dissipation openings 214 are opened on the outer sheath 210 on the side of the cushion support frame 220, which is convenient for the heat dissipation of the main body 110 and is relatively practical.

[0028] Working principle and usage process of the present utility model: First, fix the fixing ring 211 and the support frame 212 at both ends of the main body 110, then put the outer sheath 210 on the outside of the main body 110, wrap both ends of the outer sheath 210 with the fastening ring 240 at the outer end position of the support frame 212, and then fasten with the binding belt 250 so that the anti-slip piece 270 presses on the connecting wire 130 to complete the fixation.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
