Description

Technical Field

[0001] This utility model relates to the field of fire safety technology for new energy vehicle batteries, specifically to a nozzle bend and a nozzle assembly with the nozzle bend installed. Background Technology

[0002] With the popularization and development of new energy vehicles, their fire safety has gradually become a major public concern. The battery systems of new energy vehicles are characterized by high energy density and flammability, thus posing a greater fire safety risk than traditional gasoline-powered vehicles. Existing new energy vehicles are often equipped with fire sprinklers, such as... Figures 1 to 3 As shown; however, in existing nozzle bends and connecting bases, because the outer diameter of the sealing end of the bend is larger than the outer diameter of the pipe body, when the nozzle bend is installed into the connecting base of the nozzle assembly, a gap exists between the pipe body and the base cavity, such as... Figure 3 As shown at point A, when the positioning screw is used for fixing, the tightening force on one side will cause the tube to tilt or shift, and will loosen the seal between the tube and the base cavity, creating gaps and causing leakage. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing background technology and provide a nozzle bend and a nozzle assembly with the nozzle bend installed.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a nozzle bend tube, comprising a tube body with multiple bends and a hollow interior. A positioning component and a support component are provided on the outer wall of the upper interface section of the tube body. The end of the upper interface section is a sealing ring protrusion. The protrusion height of the support component relative to the side wall of the tube body is flush with the outer diameter of the sealing ring protrusion. The positioning component is located on one side of the outer wall of the upper interface section, and its protrusion height is greater than that of the support component.

[0005] Furthermore, the tube body has a three-section bending structure, wherein the bending angle of the upper interface section of the tube body is a right angle, the bending angle of the lower nozzle section of the tube body is an obtuse angle, and the bending directions of the two are opposite; the positioning component and the supporting component on the upper interface section are integrally formed with the tube body.

[0006] Furthermore, the positioning component is an outwardly protruding positioning block, integrally formed with the tube body.

[0007] Furthermore, the support component is ring-shaped and is fitted and fixed to the outside of the upper end interface section of the pipe body, and is spaced apart from the aforementioned sealing ring, with the outer diameters of both being equal.

[0008] As another optimized technical solution of this utility model, the support component is formed by the sealing ring extending along the upper interface section.

[0009] As another optimized technical solution of this utility model, the supporting component is block-shaped and fixedly installed on the opposite side of the nozzle bend mounting point.

[0010] This utility model also claims protection for a nozzle assembly with a nozzle bend, including the aforementioned nozzle bend and a corresponding connecting mounting base. The connecting mounting base has a bend docking cavity, and the interior of the bend docking cavity has a sealing ring mounting groove, in which a sealing ring is embedded. The cavity sidewall of the bend docking cavity has a fixing through hole, in which a positioning bolt is threaded. The open end sidewall of the bend docking cavity has a positioning slot, and the upper end interface section of the aforementioned nozzle bend is inserted into the bend docking cavity, with the positioning component corresponding to the positioning slot.

[0011] Furthermore, the outer diameter of the sealing ring protrusion in the nozzle bend is equal to the inner diameter of the bend's mating cavity.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure, and the positioning component can effectively prevent the bend from rotating and achieve the pre-positioning effect; the supporting component can effectively prevent the bend from loosening or shifting during the fixing process, playing a strong and secure sealing role and preventing leakage.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0026] Example 1,

[0027] like Figure 4 and Figure 5As shown, a nozzle bend includes a tube body 1, which is a three-section bent structure. From top to bottom, it can be divided into an upper interface section 11, a middle support section, and a lower nozzle section 12, which are sequentially fixedly connected and integrally formed. The tube body 1 is open at both ends and hollow inside. The upper interface section 11 and the middle support section are bent at a right angle, and the lower nozzle section 12 and the middle support section are bent at an obtuse angle. The bending extension direction of the lower nozzle section 12 is opposite to that of the upper interface section 11. The end of the upper interface section 11 is a sealing ring protrusion 2, the outer diameter of which is larger than the diameter of the tube body. A positioning component 4 and a support component 3 are fixedly provided on the outer wall of the upper interface section 11. The support component 3 is annular and coaxially fitted and fixed to the outer side of the upper interface section 11. Its outer diameter is equal to the outer diameter of the sealing ring protrusion 2 and is spaced apart from it. The positioning component 4 is an outwardly protruding positioning block, fixedly installed on one side of the outer wall of the upper interface section 11 and integrally formed therewith. Its outward protrusion height relative to the outer wall of the upper interface section is greater than the outer diameter of the support component 3. The inner wall of the lower nozzle section 12 is provided with an internal thread 5 for threaded connection of the nozzle 14.

[0028] The technical solution described in this utility model also discloses a nozzle assembly with a nozzle bend, such as... Figure 6 and Figure 7 As shown, it includes the aforementioned nozzle bend and its corresponding connecting mounting base 6, combined with... Figure 8 and Figure 9 As shown, the connecting mounting base 6 is provided with a bent pipe docking cavity 7. The inside of the bent pipe docking cavity 7 is provided with a sealing ring mounting groove 10 that surrounds its circumferential sidewall. A sealing ring is embedded in the groove. When the upper end interface section 11 of the nozzle bent pipe is inserted into the bent pipe docking cavity 7, the sealing ring protrusion 2 corresponds exactly to the sealing mounting groove 10. Its outer diameter is equal to the inner diameter of the bent pipe docking cavity 7, and its outer sidewall can form a sealing connection with the sealing ring. The cavity sidewall of the bent pipe docking cavity 7 is also provided with a fixing through hole 8, located outside the sealing ring mounting groove 10. A positioning bolt 13 is threaded inside the hole. The opening end sidewall of the bent pipe docking cavity 7 is provided with a positioning slot hole 9. When the upper interface section 11 of the above-mentioned nozzle bend is inserted into the bend docking cavity 7, the positioning component 4 on it is exactly aligned with the positioning slot 9 at the corresponding location to achieve pre-positioning and prevent the bend from rotating; the annular support component 3 on it is exactly in contact with the inner wall of the bend docking cavity 7, so that the nozzle bend is always in the center position. When fixed by the positioning bolt 13, the inner end of the positioning bolt 13 is directly opposite the gap between the support component 3 and the sealing ring protrusion 2. Its unilateral tightening force will not push the bend to shift, playing a strong and safe role.

[0029] Example 2,

[0030] A nozzle bend includes a pipe body 1, on the outer wall of its upper interface section 11, a positioning component 4 and a support component 3 are provided. The overall structural features of the nozzle bend are roughly the same as those of the technical solution described in Embodiment 1 above. The difference between the two is that the support component 3 is also arranged in a ring shape and is formed by extending the sealing ring protrusion 2 along the direction of the upper interface section 11.

[0031] Example 3,

[0032] A nozzle bend includes a pipe body 1, on the outer wall of its upper interface section 11, a positioning component 4 and a support component 3. The overall structural features of the nozzle bend are roughly the same as those of the technical solution described in Embodiment 1 above. The difference between the two is that the support component 3 is block-shaped and fixedly installed on the outer wall of the upper interface section 11, opposite to the positioning bolt 13 at the connection and fixing point. The protrusion height of the block-shaped support component 3 relative to the side wall of the pipe body is flush with the outer diameter of the sealing ring protrusion 2, ensuring that it can be inserted into the bend docking cavity 7, so that the nozzle bend is in its center position and preventing displacement.

[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
