Description

Technical Field

[0001] The utility model relates to a flange for a sewage pipe. Background Art

[0002] Flange is a common mechanical accessory used to connect two pipes or equipment to achieve sealing and connection. Flanges are widely used in sewage pipes. In order to prevent pollutants in the pipe from flowing from the first-level pipe into the next-level pipe, some sewage pipe flanges are equipped with filters to block pollutants, and then the blocked pollutants are discharged separately using the matching discharge pipes. The filters of existing sewage pipe flanges are usually fixed in the flanges with bolts, but the environment in the sewage pipes is poor and the light is dim, and it is very inconvenient to remove the filters by turning the bolts. Therefore, it is necessary to develop a sewage pipe flange to solve the above problems. Utility Model Content

[0003] The purpose of the present utility model is to provide a flange for a sewage pipe to solve the problems raised in the above background technology.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] A flange for a sewage pipe comprises a flange cylinder, a flange plate is provided on the outside of the flange cylinder, a plurality of mounting holes are provided in a ring shape on the flange plate, a filter screen is provided in the flange cylinder, a fixing block is provided on one side of the filter screen, the fixing block is fixed on the inner wall of the flange cylinder, and a locking assembly is provided on the other side of the filter screen, the locking assembly comprises a locking rod, one end of the locking rod is fixed on the filter screen, and the other end of the filter screen is provided with a bending head, the locking rod and the bending head are an integral structure, a rubber sleeve is provided on the bending head, and a locking groove corresponding to the bending head is provided on the inner wall of the flange cylinder.

[0006] Preferably, one side wall of the locking groove is in the shape of an inclined surface, and the rubber sleeve abuts against the inclined surface of the locking groove.

[0007] Preferably, there are four locking assemblies, which are arranged in a cross shape on the filter.

[0008] Preferably, there are multiple fixing blocks, and the multiple fixing blocks are arranged on the inner wall of the flange cylinder in a ring shape and at equal intervals.

[0009] Preferably, the edge portion of the filter screen is a metal ring, and the middle portion of the filter screen is a metal mesh.

[0010] The beneficial effects of the utility model are as follows: the filter screen of the utility model is stably installed in the flange barrel by utilizing the locking assembly. When removing the filter screen, it is only necessary to toggle the locking rod to bend the locking rod until the bending head and the rubber sleeve are disengaged from the locking groove, and then pull the locking rod to slide the filter screen out of the flange barrel. The operation is simple and convenient, and the operation is not easily affected by factors such as poor environment and dark light in the sewage pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See Figures 1 to 4 The sewage pipe flange shown includes a flange cylinder 11, a flange plate 12 is provided on the outside of the flange cylinder 11, and a plurality of mounting holes 13 are provided in an annular shape on the flange plate 12. A filter screen 15 is provided in the flange cylinder 11, and a fixing block 14 is provided on one side of the filter screen 15. The fixing block 14 is fixed on the inner wall of the flange cylinder 11, and a locking assembly 16 is provided on the other side of the filter screen 15. The locking assembly 16 includes a locking rod 18, one end of the locking rod 18 is fixed on the filter screen 15, and the other end of the filter screen 15 is provided with a bending head 19. The locking rod 18 and the bending head 19 are an integral structure. The bending head 19 is provided with a rubber sleeve 20, and the inner wall of the flange cylinder 11 is provided with a locking groove 17 corresponding to the bending head 19.

[0018] Furthermore, one side wall of the locking groove 17 is in the shape of an inclined surface, and the rubber sleeve 20 abuts against the inclined surface of the locking groove 17; when the rubber sleeve 20 abuts against the inclined surface of the locking groove 17, the bending head 19 is bent toward the locking rod 18 at a certain angle, thereby utilizing elastic force to make the rubber sleeve 20 tightly abut against the inclined surface of the locking groove 17, so that the locking assembly 16 and the locking groove 17 are stably engaged.

[0019] Furthermore, there are four locking assemblies 16, which are arranged in a cross shape on the filter screen 15; there are also four locking grooves 17 on the inner wall of the flange cylinder 11, which correspond one-to-one to the four locking assemblies 16, and the four locking assemblies 16 are all engaged with the corresponding locking grooves 17 to ensure the stability of the installation of the filter screen 15.

[0020] Furthermore, there are multiple fixing blocks 14, which are arranged in a ring shape and at equal intervals on the inner wall of the flange tube 11; the multiple fixing blocks 14 press against one side of the filter screen 15 and cooperate with the locking assembly 16 to fix the filter screen 15 in the flange tube 11.

[0021] Furthermore, the edge portion of the filter screen 15 is a metal ring, and the middle portion of the filter screen 15 is a metal mesh.

[0022] The working principle of the present invention is that when the filter screen 15 is installed in the flange cylinder 11, when the rubber sleeve 20 is against the inclined surface of the locking groove 17, the bending head 19 is bent at a certain angle toward the locking rod 18, so that the rubber sleeve 20 is tightly against the inclined surface of the locking groove 17 by elastic force, so that the locking assembly 16 is stably engaged with the locking groove 17, so that the filter screen 15 is pressed between the fixing block 14 and the locking assembly 16, so that the filter screen 15 is stably installed in the flange cylinder 11. When removing the filter screen 15, the locking rod 18 is toggled to bend the locking rod 18 until the bending head 19 and the rubber sleeve 20 are disengaged from the locking groove 17, and then the locking rod 18 is pulled to slide the filter screen 15 out of the flange cylinder 11. The operation is simple and convenient.

[0023] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
