Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-6, an embodiment of the present utility model is provided: the pipeline filter comprises a main body part 1, wherein one side of the main body part 1 is provided with a liquid inlet 4, and the other side of the main body part 1 is provided with a liquid outlet 2; and a filtering mechanism 3 is arranged on the main body part 1; specifically, the filtering mechanism 3 includes a filter 35 for separating the liquid inlet 4 from the liquid outlet 2; on the other hand, the liquid that has been fed can be filtered by the filter means 3.

The filter 35 is fixed in the main body part 1 through the gland 30, so that the filter mechanism 3 and the main body part 1 are convenient to assemble and disassemble, and meanwhile, the spring 32 is arranged between the gland 30 and the filter 35, so that the condition of overlarge water pressure can be overcome by utilizing the contraction of the spring 32, and the condition of overlarge water pressure can be overcome by utilizing the expansion of the spring 32; based on this, the water pressure inside the main body portion 1 can be automatically stabilized by the spring 32 to realize the capability of automatic pressure stabilization.

Further, since the filter 35 includes the first housing 33 and the second housing 34, and the first housing 33 and the second housing 34 are closed to form a cavity for filling the filtering material, the filtering capacity of the apparatus can be adjusted by changing the filtering material of different levels.

On the basis of the above scheme, since the first connecting rod 31 is further arranged between the gland 30 and the filter 35, and the spring 32 is sleeved outside the first connecting rod 31, the filter 35 can be guided to slide inside the main body part 1 by the first connecting rod 31; secondly, the spring 32 can be fixed to guide the unification of the expansion and contraction directions of the spring 32; thirdly, the filter 35 is stably positioned in the main body part 1 by the cooperation of the spring 32 and the first connecting rod 31.

Since the first housing 33 is provided with a connecting portion 36 inside; the second housing 34 is connected to the connecting portion 36 through a second connecting rod 37, so that the first housing 33 and the second housing 34 are assembled conveniently, and in particular, the second connecting rod 37 is in threaded fit with the connecting portion 36;

in addition, the other end of the connecting portion 36 is connected with the first connecting rod 31, and further, one end of the first connecting rod 31 is inserted into the connecting portion 36, at this time, the first housing 33 may slide at one end of the first connecting rod 31, and then the second connecting rod 37 is in threaded engagement with the connecting portion 36, so as to prevent the first housing 33 from sliding off the first connecting rod 31.

Specifically, after the second connecting rod 37 is completely screwed into the connecting portion 36, a certain gap is formed between the facing surfaces of the second connecting rod 37 and the first connecting rod 31, for example, the gap is one centimeter, and this one centimeter gap is the maximum limit of the downward movement of the first housing 33; the spring 32 is compressed to the minimum and is the maximum limit of the upward movement of the first housing 33.

In order to facilitate the assembly and disassembly of the second housing 34 and the first connecting rod 31, a connecting hole 38 is disposed on a surface of the second housing 34 away from the first housing 33 and a surface of the first connecting rod 31 away from the gland 30, wherein the connecting hole 38 is a hexagon socket.

On the basis of the scheme, as the end, far away from the gland 30, of the main body part 1 is also provided with the bottom cover 5, and the gland 30 and the bottom cover 5 are uniformly in threaded fit with the main body part 1, both ends of the main body part 1 can be exposed, and the filtering mechanism 3 can be conveniently taken out of the main body part 1; secondly, the impurities at the bottom of the main body part 1 are removed by disassembling the bottom cover 5.

Further, since the filter 35 is made of stainless steel, the structural strength of the filter 35 is enhanced, and round holes are uniformly distributed on the outer wall surface of the filter 35, so that the round holes have the filtering capability while not affecting the water flow. In addition, the filter 35 can also perform a filtering function without using a filter material by replacing round holes having different diameters. When the filter material is used, the round hole can finish the primary filtering function.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
