The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 6, the embodiment of the present invention discloses a fastening device 100, the fastening device 100 is used for binding a pipeline 200 and a valve 300 which are communicated with each other, an axis of the valve 300 is intersected with an axis of the pipeline 200, and specifically, the valve 300 is disposed on a side wall of the pipeline 200. The disclosed fastening device 100 includes a ring 110, a first fastening strap 120, and a second fastening strap 130.

The ring member 110 is fixedly installed on the valve 300, and the first end of the first fastening band 120 and the first end of the second fastening band 130 are connected to the ring member 110. First fixed band 120 and second fixed band 130 are disposed oppositely, and the second end of first fixed band 120 and the second end of second fixed band 130 are all wound to the side of pipeline 200 departing from valve 300, and the second end of first fixed band 120 and the second end of second fixed band 130 are connected. At this time, the ring member 110 serves to fix the first end of the first fastening band 120 and the first end of the second fastening band 130, and the ring member 110 is fixed with respect to the valve 300. The first fastening band 120 and the second fastening band 130 are disposed opposite to each other, and at this time, a portion of the pipeline 200 and a portion of the valve 300 are located between the first fastening band 120 and the second fastening band 130, and a second end of the second fastening band 130 and a second end of the first fastening band 120 are wound around to a back side of the pipeline 200 and connected, thereby binding the valve 300 and the pipeline 200.

In the embodiment disclosed in the present application, the fastening device 100 can bind the pipeline 200 and the valve 300, so that even if the connection between the pipeline 200 and the valve 300 fails, the valve 300 can be prevented from falling off the pipeline 200, and the connection reliability between the valve 300 and the pipeline 200 is further improved.

In addition, the fastening device 100 can bind the pipeline 200 and the valve 300, and the fastening device 100 can apply a certain pre-pressure to the valve 300 and the pipeline 200, so that the connection between the valve 300 and the pipeline 200 is more stable, and the connection structure between the valve 300 and the pipeline 200 is not easily damaged.

In addition, the fastening device 100 can apply a certain pre-pressure to the valve 300 and the pipeline 200, so that when the valve 300 is pulled or collided by a person, a certain pre-pressure is applied to the valve 300, and the valve 300 is not easy to pull and move, so that the valve 300 and the pipeline 200 are not easy to damage, and the service lives of the valve 300 and the pipeline 200 are prolonged.

Optionally, the ring member 110 is sleeved on the valve body of the valve 300, and since the valve body has a structure with smaller end parts and larger middle parts, the inner diameter of the ring member 110 is larger than the end part diameter of the valve body and smaller than the middle part diameter of the valve body, so that the ring member 110 can be fixed relative to the valve 300 when being sleeved on the valve 300.

In the above embodiment, the valve 300 and the pipeline 200 may be connected by screw threads, welding, etc., but may be connected by other methods.

Alternatively, ring member 110, first strap 120, and second strap 130 may be formed from flat iron, although other materials may be used. The ring-shaped member 110 may be formed by punching with a punch or by cutting with a laser, and the specific forming manner of the ring-shaped member 110 is not limited herein.

In an alternative embodiment, ring member 110 may be welded to both first strap 120 and second strap 130. At this time, the ring member 110 is welded to the first strap 120 and the second strap 130, and the connection strength of the ring member 110 to the first strap 120 and the second strap 130 can be improved.

Of course, ring 110 and first strap 120 and second strap 130 may be connected by snapping, riveting, screwing, and the like, without limitation.

In the above embodiment, when the fastening device 100 binds the valve 300 and the pipeline 200, the second end of the first fixing band 120 and the second end of the second fixing band 130 may be welded, and the first fixing band 120 and the second fixing band 130 need to be welded, so that the first fixing band 120 and the second fixing band 130 are difficult to connect and inconvenient to operate.

In addition, when the fastening device 100 is removed, the first fixing strap 120 and/or the second fixing strap 130 need to be cut, and the first fixing strap 120 and the second fixing strap 130 can be removed by cutting, which causes a difficulty in removing the fastening device 100 and also makes the fastening device 100 difficult to use for multiple times.

In another alternative embodiment, the fastening device 100 may further include a first screw connector 140, the second end of the first fastening strap 120 may be formed with a first connection hole 121, and the second end of the second fastening strap 130 may be formed with a second connection hole 131. The second end of the first strap 120 and the second end of the second strap 130 may be connected through the first threaded connector 140, the first connection hole 121, and the second connection hole 131.

In this embodiment, when the fastening device 100 fastens the valve 300 and the pipeline 200, the ring member 110 is fitted over the valve 300, and the first screw connector 140 passes through the first connection hole 121 and the second connection hole 131, thereby completing the connection between the second end of the first strap 120 and the second end of the second strap 130. When the fastening device 100 is removed, the first threaded connector 140 is withdrawn from the first coupling hole 121 and the second coupling hole 131, and the second end of the first strap 120 and the second end of the second strap 130 are separated. Therefore, the first fixing strap 120 and the second fixing strap 130 are less difficult to connect and convenient to operate. In addition, when the fastening device 100 is removed, there is no need to break the fastening device 100, thereby enabling the fastening device 100 to be reused multiple times.

Alternatively, the first threaded connector 140 may include a bolt and a nut, but may also have other threaded structures, which is not limited herein.

In order to improve the compatibility of the fastening device 100, in another alternative embodiment, as shown in fig. 4, the number of the first connection holes 121 may be multiple, and multiple first connection holes 121 may be arranged at intervals along the extending direction of the first fixing strip 120. The number of the second coupling holes 131 may be plural, and the plurality of second coupling holes 131 may be arranged at intervals along the extending direction of the second fixing band 130. The plurality of first connection holes 121 and the plurality of second connection holes 131 correspond one to one. In this scheme, the number of the first connection holes 121 and the second connection holes 131 is multiple, so that when the fastening device 100 is used for binding the valve 300 and the pipeline 200, different first connection holes 121 and second connection holes 131 can be selected according to the sizes of the valve 300 and the pipeline 200 for connection, so that the pipelines 200 and the valves 300 with different sizes can be bound, and further the compatibility of the fastening device 100 is improved.

For example, the first fixing band 120 and the second fixing band 130 need to be wound around the side of the pipeline 200 facing away from the valve 300, and thus the larger the diameter of the pipeline 200, the longer the required length of the first fixing band 120 and the second fixing band 130 is, and thus by selectively providing a plurality of first connection holes 121 and a plurality of second connection holes 131, pipelines 200 of different diameters can be satisfied.

In the above embodiment, the ring member 110 may be an integral structural member, in which case the ring member 110 needs to be sleeved on the valve 300 from an end of the valve 300 away from the pipeline 200, and when the pipeline 200 and the valve 300 are located at corners and the like, for example, a gap between the valve 300 and a side wall (e.g., a wall) of a roadway is small, so that the ring member 110 is difficult to be sleeved on the valve 300.

Based on this, in another alternative embodiment, as shown in fig. 5, ring member 110 may include a first arc member 111 and a second arc member 112, first arc member 111 and second arc member 112 are detachably connected, first arc member 111 and second arc member 112 enclose a ring structure, a first end of first strap 120 is connected to first arc member 111, and a first end of second strap 130 is connected to second arc member 112.

In a specific installation process, the first arc-shaped member 111 and the second arc-shaped member 112 are snapped on the valve 300, and then the first arc-shaped member 111 and the second arc-shaped member 112 are connected, so that the ring-shaped member 110 is sleeved on the valve 300.

In this embodiment, the annular member 110 is formed by splicing two arcuate members. When the gap between the valve 300 and the side wall of the roadway is small, the first arc-shaped part 111 and the second arc-shaped part 112 can be directly buckled on the valve 300 without being sleeved in the gap between the valve 300 and the side wall of the roadway, so that the assembly mode of the annular part 110 and the valve 300 is simpler.

Further, the fastening device 100 may further include a second threaded connection 151 and a third threaded connection 152, wherein one end of the first arc-shaped member 111 is opened with a third connection hole 1111, and the other end of the first arc-shaped member 111 is opened with a fourth connection hole 1112. One end of the second arc-shaped member 112 is formed with a fifth connecting hole 1121, and the other end is formed with a sixth connecting hole 1122.

One end of the first arc-shaped member 111 and one end of the second arc-shaped member 112 may be connected through the second screw connection 151, the third connection hole 1111, and the fifth connection hole 1121, and the other end of the first arc-shaped member 111 and the other end of the second arc-shaped member 112 may be connected through the third screw connection 152, the fourth connection hole 1112, and the sixth connection hole 1122.

In this scheme, first arc 111 and second arc 112 pass through threaded connection spare to make things convenient for first arc 111 and second arc 112 to dismantle, simultaneously, also make first arc 111 and second arc 112 have better joint strength.

In the above embodiment, the second and third threaded

connections

151 and 152 may have the same structure as the first threaded connection 140.

In order to further improve the compatibility of the fastening device 100, in another alternative embodiment, as shown in fig. 6, the number of the third connecting hole 1111 and the fourth connecting hole 1112 may be multiple, and multiple third connecting holes 1111 and fourth connecting holes 1112 may be arranged at intervals in the circumferential direction of the first arc-shaped member 111.

The number of the fifth connection holes 1121 and the sixth connection holes 1122 may be plural, and the plural fifth connection holes 1121 and sixth connection holes 1122 may be arranged at intervals in the circumferential direction of the second arc-shaped member 112.

The plurality of third connection holes 1111 and the plurality of fifth connection holes 1121 may correspond one to one, and the plurality of fourth connection holes 1112 and the plurality of sixth connection holes 1122 may correspond one to one. In this embodiment, different connecting holes can be selected for connection through different outer diameters of the valve body of the valve 300, so that the compatibility of the fastening device 100 can be further improved.

In another alternative embodiment, the fastening device 100 may further include a set block disposed between the first strap 120 and/or the second strap 130 and the pipe. In this embodiment, the adjustment block may be added between the first fixing band 120 and/or the second fixing band 130 and the pipe, which is equivalent to increase the outer diameter of the pipe 200, so that the first fixing band 120 and/or the second fixing band 130 are tightened, and the fastening device 100 is not easy to slide on the pipe, thereby improving the binding effect.

In another alternative embodiment, the configuration of the first fastening tape 120 may be the same as the configuration of the second fastening tape 130. At this time, the first fixing strap 120 and the second fixing strap 130 can be used interchangeably, so that the interchangeability of the first fixing strap 120 and the second fixing strap 130 is improved, and the fastening device has a simpler structure, is simpler and more convenient to manufacture, and has lower cost.
