Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and particularly relates to a waterproof flange. Background Art

[0002] A waterproof flange is a flange part with waterproof effect. The authorized patent "Waterproof Connection Structure of Fan Air Duct" with the publication (announcement) number of CN220687687U and the publication (announcement) date of March 29, 2024 discloses an implementable waterproof flange. This kind of waterproof connection flange separates the waterproof function. The upper end is connected to the air collecting duct and the lower end is connected to the air duct. The roof plate is hidden under the rain cap on the periphery of the flange and is connected to the air duct and the flange, so as to cooperate to realize the function of discharging internal rainwater to the outside and preventing rain from the outside. In rainy weather, the rainwater slanting onto the inner side of the air collecting duct all flows through the drain port of the air collecting duct and through the flange rain cap to the outside and will not enter the room through the fan. Since the upper end opening of the roof plate is hidden under the flange rain cap, the rain slanting onto the outer wall of the air collecting duct or onto the flange rain cap outdoors all flows through the flange rain cap and is discharged to the outside and will not enter the room, nor will rain enter the room from the opening of the roof plate, and effective waterproofing (rain prevention) can be achieved.

[0003] However, although the existing waterproof connection flange in the livestock ventilation equipment industry has the function of roof waterproofing, it has deficiencies. That is, as an intermediate part connecting the air collecting duct and the air duct, considering that the air collecting duct is located above the roof and its size above the roof is not restricted, the air collecting duct will swing under the influence of crosswind in strong wind weather, and the swing is transmitted to the air duct through the waterproof connection flange, thus affecting the stability of the whole machine.

[0004] Therefore, in view of the deficiencies of the above-mentioned solution in actual production and implementation, it is modified and improved. At the same time, in line with the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, a waterproof flange is provided specifically to solve the technical problem of poor stability when the existing waterproof flange is used. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a waterproof flange to solve the technical problem of poor stability when the existing waterproof flange is used.

[0006] The technical solution of the utility model is realized as follows:

[0007] A waterproof flange, comprising a flange body, the flange body successively includes a columnar section, a conical section, a flat section and a waterproof inclined section from top to bottom. A flanging is provided at the top of the columnar section. The diameter of the bottom position of the conical section is larger than that of the top position of the conical section. The flat section is annular. The waterproof inclined section is a conical surface with a larger bottom diameter than the top diameter. The diameter of the top of the waterproof inclined section is larger than that of the bottom position of the conical section.

[0008] When this waterproof flange is in use, it is located in the middle of the wind collecting cylinder and the wind cylinder connection layer. Its flanging is hung on the wind cylinder (to prevent rainwater from leaking into the house through the opening of the fitting gap between the waterproof flange and the wind cylinder). Its columnar section extends to the drainage port of the wind collecting cylinder, and the end of its columnar section is transitioned to the flat section through the conical section (inclined surface), so as not to cause blockage to the drainage port of the wind collecting cylinder.

[0009] This waterproof flange is applicable to both single-layer and double-layer wind cylinders. When the conical section of the waterproof flange is transitioned to the flat section, due to the existence of this flat surface, the waterproof flange is compatible with the maximum outer diameters of both single-layer and double-layer wind cylinders. The flat section is connected to the waterproof inclined section. This waterproof inclined section is actually a conical inclined surface that plays a waterproof role. The opening of the roof plate is hidden under this inclined surface and fixed to the wind cylinder to achieve the rainproof function.

[0010] As a preferred implementation manner, the columnar section, the conical section, the flat section and the waterproof inclined section are of an integral structure.

[0011] During processing, it is integrally formed, with stable structure, durability and not easy to be damaged.

[0012] As a preferred implementation manner, a plurality of connection holes are uniformly arranged on the side wall of the columnar section. The connection holes are through holes or bolt holes.

[0013] The beneficial effects of the present utility model are:

[0014] The waterproof flange proposed by the present utility model is only used for waterproofing and does not change the connection method of directly connecting the wind collecting cylinder and the wind cylinder. Therefore, no indirect connection section is added, so as not to increase the burden on the stability of the whole machine. Therefore, it has good stability during use, and solves the technical problem of poor stability of the existing waterproof flange during use.

[0015] This waterproof flange is located in the middle of the wind collecting cylinder and the wind cylinder connection layer, and because its self-provided flanging is equivalent to being hung on the wind cylinder, the stability of the whole machine in strong wind weather is not changed while realizing the waterproof function in the way of connecting the three. The roof plate is hidden under the waterproof flange and connected to the wind cylinder, so as to cooperate to realize the external drainage of internal rainwater and the external rainproof function, and there is no need for accessories such as sealants and waterproof coatings that are easily affected by environmental temperature.

[0027] As Figures 1 to 3 shown, a waterproof flange includes a flange body 8, and the flange body 8 successively includes a columnar section 2, a conical section 3, a flat section 4 and a waterproof inclined section 5 from top to bottom. A flanging 1 is arranged at the top of the columnar section 2. The diameter of the bottom position of the conical section 3 is larger than that of the top position of the conical section 3. The flat section 4 is annular. The waterproof inclined section 5 is a conical surface with a bottom diameter larger than the top diameter, and the diameter of the top of the waterproof inclined section 5 is larger than that of the bottom position of the conical section 3.

[0028] Figure 4 , Figure 5 is a schematic diagram of the use state of the present utility model, mainly used to intuitively show the positional relationship and mutual cooperation with the wind collecting cylinder 7, the roof plate 9, and the double-layer wind cylinder 10 (a kind of wind cylinder, representing the wind cylinder for illustration).

[0029] When this waterproof flange is in use, it is located in the middle of the wind collecting cylinder 7 and the wind cylinder connection layer. Its flanging 1 is hung on the wind cylinder (to prevent rainwater from leaking into the house through the gap opening between the waterproof flange and the wind cylinder), its columnar section 2 extends to the drainage port of the wind collecting cylinder 7, and the end of its columnar section 2 is transitioned to the flat section 4 with the conical section 3 (inclined surface), so as not to block the drainage port of the wind collecting cylinder 7.

[0030] This waterproof flange is applicable to both single-layer wind cylinders and double-layer wind cylinders. When the conical section 3 of the waterproof flange transitions to the flat section 4, due to the existence of this flat surface, the waterproof flange is compatible with the maximum outer diameters of both single-layer wind cylinders and double-layer wind cylinders. The flat section 4 is connected to the waterproof inclined section 5. This waterproof inclined section 5 is actually a conical inclined surface that plays a waterproof role. The opening of the roof plate 9 is hidden under this inclined surface and fixed to the wind cylinder to achieve the rainproof function.

[0031] As a preferred embodiment, the columnar section 2, the conical section 3, the flat section 4 and the waterproof inclined section 5 are of an integral structure.

[0032] During processing, it is integrally formed, with stable structure, durability and not easily damaged.

[0033] As a preferred embodiment, a plurality of connection holes 6 are evenly arranged on the side wall of the columnar section 2. The connection holes 6 can be through holes or bolt holes, etc. according to actual use needs.

[0034] The beneficial effects of the present utility model are as follows:

[0035] The waterproof flange proposed by the present utility model is only used for waterproofing and does not change the connection mode of directly connecting the wind collecting cylinder 7 with the air duct (i.e., Figure 4 the double-layer air duct on it), so no indirect connection section is added, thus not adding burden to the stability of the whole machine. Therefore, it has good stability during use and solves the technical problem of poor stability of the existing waterproof flange during use.

[0036] This waterproof flange is located in the middle of the connection layer between the wind collecting cylinder and the air duct (i.e., Figure 4 the double-layer air duct on it), and because it has a self - flanging, it is equivalent to hanging on the air duct. In the way of connecting the three, it realizes the waterproof function without changing the stability of the whole machine in strong wind weather. The roof plate is hidden under the waterproof flange and connected to the air duct, so as to cooperate to realize the function of discharging internal rainwater and preventing external rain, and no accessories such as sealants and waterproof coatings that are easily affected by environmental temperature are required.

[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement; when the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
