Description

Technical Field

[0001] The present application relates to the field of one-way valves, and in particular to a one-way valve structure. Background Art

[0002] A check valve is a valve, also known as a non-return valve or a reverse valve, that is used to control the one-way flow of fluid in a pipe, allowing the fluid to flow freely in one direction, while blocking the fluid from passing in the reverse direction.

[0003] In the prior art, such as the Chinese publication number CN203189810U, the utility model provides a one-way valve structure, which includes a first connecting pipe, a second connecting pipe and a valve housing, the valve housing is provided with an air inlet and an air outlet, the air outlet of the valve housing is connected to the first connecting pipe, the air inlet of the valve housing is connected to the second connecting pipe, a conical valve core is provided in the valve housing, the conical valve core is connected to a compression spring, the conical valve core can move up and down in the valve housing, the second connecting pipe is provided with a conical valve port, the conical valve core and the conical valve port are sealed. The one-way valve structure is provided with a conical valve core in the valve housing, and a conical valve port is provided on the second connecting pipe. The contact surface of the conical valve core and the conical valve port is relatively large, which can effectively improve the sealing effect of the one-way valve, prevent the one-way valve from leaking in the reverse direction, and improve the quality of the one-way valve.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that some existing one-way valves connect the two together through threads when connected to the pipeline. However, after long-term use, the threaded connection may cause the one-way valve and the pipeline to loosen or cause a tiny gap due to vibration, resulting in leakage problems. At the same time, the threaded connection requires the use of tools for tightening and loosening, which is troublesome during installation and maintenance, especially in compact spaces or inconvenient locations. In addition, some existing one-way valves have no protective structure, which may cause the valve to be damaged when the valve is accidentally hit. Utility Model Content

[0005] The present application provides a one-way valve structure in which the one-way valve and the pipeline are connected without using threads, and the connection method is simple and convenient, thereby improving the installation efficiency of the valve. Moreover, when the one-way valve is impacted, the two parts have a protective effect on the one-way valve, and the protective effect is relatively good, thereby preventing the one-way valve from being damaged.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a one-way valve structure, the one-way valve comprising:

[0007] Valve housing;

[0008] Two sealing sleeves are fixedly arranged on both sides of the valve housing, and a first connecting ring is fixedly arranged on one side of the two sealing sleeves;

[0009] Two transverse shafts are respectively fixedly arranged on one side of the two first connecting rings, and the outer surfaces of the two transverse shafts are movably sleeved with bottom plates;

[0010] Two second connecting rings are fixedly arranged on one side of the two bottom plates respectively, and a first pressing plate is fixedly arranged on one side of the two second connecting rings;

[0011] Two connecting rods are fixedly arranged on one side of the two first pressing plates, and sleeves are fixedly arranged on one side of the two connecting rods;

[0012] A plurality of telescopic rods are respectively and movably embedded in the inner walls of the two sleeves, and a triangular block is fixedly arranged on one side of the plurality of telescopic rods.

[0013] As a further improvement scheme of the present application: two second pressing plates are respectively fixedly arranged on one side of the two first connecting rings, and one side of the two second pressing plates is provided with a through hole.

[0014] As a further improvement of the present application: the plurality of telescopic rods are grouped in pairs, the two groups of telescopic rods are connected by return springs, and the two return springs are movably arranged on the inner walls of the two sleeves respectively.

[0015] As a further improvement of the present application: two support rods are fixedly provided on one side of the valve housing, and two slide cylinders are movably sleeved on the outer surfaces of the two support rods.

[0016] As a further improvement of the present application: a plurality of the slide tubes are fixedly provided with a compression spring on one side, and the plurality of the compression springs are respectively sleeved on the outer surfaces of the two support rods.

[0017] As a further improvement of the present application: a transmission rod is movably provided on one side of each of the plurality of slide cylinders, and a transmission rod is provided on the movable sleeve, and one side of each of the plurality of transmission rods is fixedly provided on one side of each of the plurality of support rods.

[0018] As a further improvement scheme of the present application: the plurality of slide cylinders are evenly divided into two groups, one side of the transmission rods of the two groups are movably provided with a boss, and the opposite sides of the two bosses are fixedly provided with a protective plate.

[0019] As a further improvement of the present application: the inner walls of the two first connecting rings and the two second connecting rings are fixedly provided with rubber pads, and the plurality of rubber pads are movably provided on the outer surfaces of the two sealing sleeves respectively.

[0020] Compared with the prior art, the advantages and positive effects of this application are:

[0021] 1. When the one-way valve is connected to the pipeline, the two pipelines are respectively sleeved on the outer surfaces of the two sealing sleeves, and the two bottom plates can rotate with the two transverse axes as axes. At this time, the two second connecting rings are rotated respectively, so that the two first pressing plates and the two transverse axes are respectively contacted together, and the multiple telescopic rods can slide inside the two sleeves respectively. At this time, the two second connecting rings are pressed so that the hypotenuses of the multiple triangular blocks touch the four sides of the through holes opened by the two first connecting rings, and the multiple triangular blocks are further pushed, so that the two groups of telescopic rods squeeze the two reset springs, and the multiple triangular blocks pass through the two first connecting rings. After entering the through hole, the elastic force generated by the two return springs pushes the multiple triangular blocks, further making the multiple triangular blocks stuck on the two first connecting rings, and the elasticity and softness of the multiple rubber pads further fix the pipeline, thereby fixing the pipeline on both sides of the one-way valve. When disassembling the pipeline, the multiple triangular blocks are pushed respectively, and the return springs are pushed by multiple telescopic rods to remove the pipeline from the valve, so that the one-way valve and the pipeline are not connected in a threaded manner. The connection method is simple and convenient, which improves the installation efficiency of the valve, and the pipeline is covered on the outer surfaces of the two sealing sleeves, and the sealing performance is also relatively good.

[0022] 2. When the one-way valve is accidentally hit by an external impact, it will first hit the two protective plates. Multiple slides can slide on the outer surfaces of the two support rods respectively. At this time, the two protective plates push the multiple transmission rods through the two bosses respectively, so that the multiple slides further slide on the two support rods to squeeze the multiple extrusion springs. When the multiple extrusion springs are squeezed, a reverse force will be generated to offset a part of the impact force received by the two protective plates, thereby protecting the valve housing. Therefore, when the one-way valve is hit, the two protective plates can protect the one-way valve, and the protection effect is relatively good, thereby preventing the one-way valve from being damaged.

At the same time, the content of the above background technology belongs to the technical cognition scope of the utility model inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute the prior art.

[0034] like Figure 1-6 As shown, the present application provides a one-way valve structure, the one-way valve comprising:

[0035] Valve housing 1;

[0036] Two sealing sleeves 2 are fixedly arranged on both sides of the valve housing 1, and a first connecting ring 201 is fixedly arranged on one side of the two sealing sleeves 2. When the one-way valve is used to connect the pipeline, the two pipelines are respectively sleeved on the outer surfaces of the two sealing sleeves 2 to reduce the connection gap between the valve and the pipeline, thereby preventing water from overflowing from the connection gap between the two.

[0037] Two transverse shafts 202 are respectively fixedly arranged on one side of the two first connecting rings 201, and the outer surfaces of the two transverse shafts 202 are movably sleeved with bottom plates 203, and the two bottom plates 203 can rotate around the two transverse shafts 202 as axes;

[0038] Two second connecting rings 204 are respectively fixedly arranged on one side of the two bottom plates 203, and a first pressing plate 206 is fixedly arranged on one side of the two second connecting rings 204. The two second connecting rings 204 can rotate around the two transverse axes 202;

[0039] Two connecting rods 207 are fixedly arranged on one side of the two first pressing plates 206, and a sleeve 208 is fixedly arranged on one side of the two connecting rods 207. The two connecting rods 207 connect the two sleeves 208 and the two first pressing plates 206 together;

[0040] The multiple telescopic rods 209 are movably embedded in the inner walls of the two sleeves 208 , and a triangular block 210 is fixedly provided on one side of the multiple telescopic rods 209 . The multiple telescopic rods 209 can slide inside the two sleeves 208 .

[0041] like Figure 1-6 As shown, two second pressing plates 212 are fixedly disposed on one side of the two first connecting rings 201 , respectively. Through holes are provided on one side of the two second pressing plates 212 to facilitate the insertion of multiple triangular blocks 210 .

[0042] like Figure 1-6 As shown, multiple telescopic rods 209 are grouped in pairs, and the two groups of telescopic rods 209 are connected by return springs 211. The two return springs 211 are movably arranged on the inner walls of the two sleeves 208 respectively. The multiple return springs 211 have elastic force, and the two return springs 211 can slide inside the two sleeves 208.

[0043] like Figure 1-6 As shown, two support rods 3 are fixedly provided on one side of the valve housing 1 , and two slide cylinders 302 are movably sleeved on the outer surfaces of the two support rods 3 , and the plurality of slide cylinders 302 can slide on the outer surfaces of the two support rods 3 respectively.

[0044] like Figure 1-6As shown, a compression spring 301 is fixedly provided on one side of the plurality of slide cylinders 302 , and the plurality of compression springs 301 are respectively sleeved on the outer surfaces of the two support rods 3 , and a reverse force is generated when the plurality of compression springs 301 are compressed.

[0045] like Figure 1-6 As shown, a transmission rod 303 is movably provided on one side of the plurality of slide cylinders 302 , and the plurality of transmission rods 303 can rotate with the connection of the plurality of slide cylinders 302 as an axis.

[0046] like Figure 1-6 As shown, multiple slides 302 are evenly divided into two groups, one side of the two groups of transmission rods 303 is movably provided with a boss 304, and the opposite sides of the two bosses 304 are fixedly provided with a protective plate 305. When the one-way valve is accidentally hit by an external impact, it will first hit the two protective plates 305. At this time, the two protective plates 305 push the multiple transmission rods 303 through the two bosses 304 respectively.

[0047] like Figure 1-6 As shown, the inner walls of the two first connecting rings 201 and the two second connecting rings 204 are fixedly provided with rubber pads 205, and the multiple rubber pads 205 are movably provided on the outer surfaces of the two sealing sleeves 2 respectively. The multiple rubber pads 205 are elastic and soft, and generate a reverse force when squeezed.

[0048] Working principle: When the one-way valve is connected to the pipeline, the two pipelines are respectively sleeved on the outer surfaces of the two sealing sleeves 2, and the two bottom plates 203 can rotate with the two transverse axes 202 as axes. At this time, the two second connecting rings 204 are rotated respectively, so that the two first pressure plates 206 and the two transverse axes 202 are respectively contacted together, and the multiple telescopic rods 209 can slide inside the two sleeves 208 respectively. At this time, the two second connecting rings 204 are pressed, so that the hypotenuses of the multiple triangular blocks 210 touch the four sides of the through holes opened by the two first connecting rings 201, and the multiple triangular blocks 210 are further pushed, so that the two groups of telescopic rods 209 squeeze the two return springs 211. After the multiple triangular blocks 210 pass through the through holes opened by the two first connecting rings 201, the elastic force generated by the two return springs 211 pushes the multiple triangular blocks 210, and further makes the multiple triangular blocks 210 stuck on the two first connecting rings 201, and the elasticity and softness of the multiple rubber pads 205 further fix the pipeline, thereby fixing the pipeline on both sides of the one-way valve. When disassembling the pipeline, the multiple triangular blocks 210 are pushed respectively, and the reset springs 211 are pushed through the multiple telescopic rods 209 to remove the pipeline from the valve, so that the one-way valve and the pipeline are not connected in a threaded manner. The connection method is simple and convenient, which improves the installation efficiency of the valve, and the pipeline is sleeved on the outer surfaces of the two sealing sleeves 2, and the sealing performance is also relatively good. When the one-way valve is accidentally hit by an external impact, it will first hit the two protective plates 305, and the multiple slides 302 can slide on the outer surfaces of the two support rods 3 respectively. At this time, the two protective plates 305 push the multiple transmission rods 303 through the two bosses 304 respectively, and further make the multiple slides 302 slide on the two support rods 3 to squeeze the multiple extrusion springs 301. When the multiple extrusion springs 301 are squeezed, a reverse force will be generated to offset a part of the impact force received by the two protective plates 305, and the valve housing 1 will be protected. Therefore, when the one-way valve is hit, the two protective plates 305 have a protective effect on the one-way valve, and the protection effect is relatively good to prevent the one-way valve from being damaged.

[0049] The above are only preferred embodiments of the application, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
