[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0027] A fast self-locking large-flow filter element, including a large-flow filter element body 1, a cover body 11 is arranged at the bottom of the large-flow filter element body 1, clamping blocks 4 are arranged on the front side and the rear side of the cover body 11, and shifting mechanisms 3 and limiting mechanisms 8 are arranged on both sides of the clamping block 4;

[0028] The limiting mechanism 8 includes a limiting block 801, a limiting pin 802, a chute 803 and a snap ring 804. The surface of the limiting block 801 is fixedly connected to the surface of the large-flow filter element body 1, the surface of the limiting pin 802 is in contact with the surface of the limiting block 801, the chute 803 is opened inside the clamping block 4, the limiting pin 802 is movably inserted inside the chute 803, the surface of the snap ring 804 is clamped to the inner wall of the clamping block 4, and the snap ring 804 is clamped to the surface of the large-flow filter element body 1.

[0029] In this embodiment: by clamping the clamping ring 804 with the large-flow filter element body 1, and then inserting the large-flow filter element body 1 and the clamping ring 804 between the two clamping rings 804 and rotating them clockwise, the rear side of the left limit pin 802 contacts the front side of the left limit block 801, and the front side of the right limit pin 802 contacts the rear side of the right limit block 801. At this time, the large-flow filter element body 1 and the cover body 11 can be connected and locked. At this time, the large-flow filter element body 1 and the cover body 11 can be connected. When the large-flow filter element body 1 needs to be disassembled and replaced, the limit pin 802 is moved downward to disengage from the limit block 801, and the large-flow filter element body 1 is rotated counterclockwise to a loose state to pull the large-flow filter element body 1 upward to separate it from the cover body 11. The large-flow filter element body 1 and the cover body 11 can be separated and replaced without rotating the large-flow filter element body 1 multiple times.

[0030] Specifically, Figure 5 As shown, the toggle mechanism 3 includes a toggle block 301, a spring 302 and a limiting groove 303. The toggle block 301 is movably connected to the inside of the clamping block 4. The surface of the toggle block 301 is fixedly connected to the surface of the limiting pin 802. The surface of the spring 302 is fixedly connected to the surface of the toggle block 301. The bottom of the spring 302 is fixedly connected to the bottom of the inner wall of the limiting groove 303.

[0031] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, screws 9 are provided on opposite sides of the two clamping blocks 4 , and the side of the screw 9 close to the clamping block 4 passes through the clamping block 4 and is connected with the internal thread of the clamping block 4 on the symmetrical side.

[0032] Specifically, Figure 5 As shown, the surface of the block 4 is in close contact with the surface of the cover 11 .

[0033] In this embodiment: by using screws 9 to connect the two clamping blocks 4, the clamping block 4 can be connected to the cover body 11, and the limiting pin 802 can be slid inside the slide groove 803 to facilitate the movement of the limiting pin 802, and the limiting pin 802 can be conveniently engaged and separated from the limiting block 801, and the spring 302 can support the shift block 301 and the limiting pin 802, so that the limiting pin 802 can be reset by the elastic force of the spring 302 after sliding.

[0034] Specifically, Figure 4 and Figure 6 As shown, the rear side of the left limiting pin 802 contacts the front side of the left limiting block 801 , and the front side of the right limiting pin 802 contacts the rear side of the right limiting block 801 .

[0035] Specifically, Figure 4 and Figure 6As shown, a screwing block 2 is fixedly connected to the top of the large-flow filter element body 1, and the number of screwing blocks 2 is several and evenly distributed on the top of the large-flow filter element body 1.

[0036] In this embodiment: By holding the screwing block 2, it is convenient to rotate the large-flow filter element body 1. Rotate the large-flow filter element body 1 until the rear side of the left limiting pin 802 contacts the front side of the left limiting block 801, and the front side of the right limiting pin 802 contacts the rear side of the right limiting block 801. At this time, the large-flow filter element body 1 can be connected and locked with the cover body 11, and the large-flow filter element body 1 can be connected to the cover body 11.

[0037] Specifically, as Figure 4 shown, a water inlet pipe 6 is fixedly communicated with the left side of the cover body 11, and a drain pipe 5 is fixedly communicated with the right side of the cover body 11.

[0038] Specifically, as Figure 6 shown, an installation plate 7 is arranged at the bottom of the cover body 11, and a bolt 10 is arranged at the bottom of the installation plate 7. The top of the bolt 10 passes through the installation plate 7 and is threadedly connected with the inside of the cover body 11.

[0039] In this embodiment: After the external pipeline is communicated with the water inlet pipe 6 and the drain pipe 5 and water is passed through, the filtering work can be carried out. By using an external connection tool to pass through the installation plate 7, the cover body 11 and the large-flow filter element body 1 can be fixedly installed.

[0040] Working principle: by clamping the clamping ring 804 on the surface of the large-flow filter element body 1, and then inserting the large-flow filter element body 1 and the clamping ring 804 between the two clamping rings 804, and then holding the screw block 2 to rotate the large-flow filter element body 1 clockwise, the large-flow filter element body 1 and the clamping ring 804 can be rotated at this time, so that the surface of the clamping ring 804 is in close contact with the inner wall of the clamping block 4, so that the rear side of the left limit pin 802 is in contact with the front side of the left limit block 801, and the front side of the right limit pin 802 is in contact with the rear side of the right limit block 801, and the large-flow filter element body 1 and the cover body 11 can be connected and locked at this time. At this time, the large-flow filter element body 1 and the cover body 11 can be connected, and the large-flow filter element body 1 can be connected to the cover body 11 without rotating the large-flow filter element body 1 multiple times. At this time, the external pipe is connected to the water inlet pipe 6 and After the drain pipe 5 is connected, water can be passed through the drainage pipe 5 to carry out filtering work. When the large-flow filter element body 1 needs to be replaced, the dial block 301 is pushed downward, and the limit pin 802 can be driven to move downward, so that the limit pin 802 is disengaged from the limit block 801, and then the large-flow filter element body 1 is rotated counterclockwise to loosen the large-flow filter element body 1, and then the large-flow filter element body 1 can be removed by pulling the large-flow filter element body 1 upward. There is no need to rotate the large-flow filter element body 1 multiple times to separate it from the cover body 11, which avoids the problem that some existing large-flow filter elements are threadedly connected to the cover body 11. When the large-flow filter element needs to be replaced, the large-flow filter element needs to be rotated multiple times to facilitate the separation of the large-flow filter element from the cover body 11 and the external pipe connected to the cover body 11, which is relatively inconvenient and affects the replacement efficiency of the large-flow filter element.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
