Description

Technical Field

[0001] The utility model relates to the field of fry breeding, and particularly relates to a fixing structure for a filter bag. Background Art

[0002] In the field of breeding fry such as zebrafish, circulating water purification treatment is required in the equipment to filter micron-sized impurities in water with micron-sized mesh holes to achieve the purpose of purifying water quality.

[0003] However, after installing a filter bag in a breeding tank or the like, due to the floating effect caused by buoyancy, the filter bag cannot be fixed to the breeding tank and needs to be manually pressed. Summary of the Utility Model

[0004] In order to solve the problem that the filter bag needs to be pressed, the utility model provides a fixing structure for a filter bag.

[0005] The technical solution of the utility model is as follows:

[0006] A fixing structure for a filter bag, characterized by comprising a filter bag ring for fixing the filter bag and a filter bag ring support plate. The outer periphery of the filter bag ring is a flanging ring, and the outer edge of the flanging ring inclines outwards. The support plate has an inner hole, and the lower side of the inner edge of the inner hole protrudes outwards. The upper surface of the protrusion is a platform, and the platform forms an annular pit structure relative to the plate surface of the support plate. The side wall of the pit has uniformly distributed inwardly protruding pressing platforms. The outermost diameter of the flanging ring is smaller than the diameter of the side wall and larger than the diameter of the most protruding point of the pressing platform.

[0007] Preferably, there are 3 pressing platforms, which are spaced 120° apart respectively.

[0008] Preferably, the outer edge of the flanging ring inclines outwards by 45 degrees.

[0009] Preferably, the bottom of the flanging ring is connected to the side wall to form a plane that can fit with the platform.

[0010] Advantageous Technical Effects of the Utility Model

[0011] A pit is arranged on the support plate of the utility model, and the side wall of the pit has protruding pressing platforms. Through the setting of the size of the outer edge of the flanging ring, it can be stuck to the pressing platform, so that stable fixation can be achieved without manual pressing.

[0012] At the same time, since the outer edge is set to be inclined, both installation and disassembly are relatively convenient. Description of the Drawings

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings. The following shows the preferred embodiments of the present utility model. It should be understood that those skilled in the art can modify the present utility model described herein and still achieve the beneficial effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation on the present utility model.

[0020] Embodiment

[0021] A filter bag fixing structure of the present embodiment, as Figures 1-4 shown, includes a filter bag ring 6 and a filter bag ring support plate 1 for fixing to the opening of the filter bag. The outer periphery of the filter bag ring 6 is a flanging ring 7 and the outer edge of the flanging ring 2 is inclined outward, preferably inclined at 45°. The support plate 1 has an inner hole 2, and the lower part of the inner edge of the inner hole 2 protrudes outward. The upper surface is a platform 3. The platform 3 forms an annular concave structure relative to the plate surface of the support plate. The side wall 4 of the concave has uniformly distributed inwardly protruding pressing tables 5. The outermost diameter of the flanging ring 7 is smaller than the diameter of the side wall and larger than the diameter of the most convex point of the pressing table. The pressing tables 5 of the present embodiment are preferably provided with 3, respectively spaced 120°.

[0022] The flanging ring of the present embodiment can be as Figure 2 shown, the bottom is connected to the side wall to form a plane 8 that fits the platform 3; or only one flanging can be left.

[0023] Due to the setting of the size of the outer edge of the flanging ring 7, it can catch the pressing table 5, so that stable fixation can be achieved without manual pressing.

[0024] At the same time, since the outer edge of the flanging ring 7 is set to be inclined, both installation and disassembly are relatively convenient, without the need to use a large force, and the structure is not easily damaged.

[0025] The above has shown and described the basic principles, main features and advantages of the present utility model. Therefore, the above description is only an embodiment of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
