Description

Technical Field

[0001] This utility model relates to the field of sealing sleeve technology, specifically a battery liquid cooling soft connection sealing sleeve. Background Technology

[0002] A battery liquid cooling flexible connection sealing sleeve is a sealing device used for flexible connection parts in a battery liquid cooling system. It is usually made of flexible material and is used to ensure reliable sealing of the flow path of coolant in the liquid cooling system and prevent coolant leakage.

[0003] A search revealed Chinese Patent Publication No. CN222015485U, which discloses a battery liquid-cooled flexible connection sealing sleeve, including a pipe joint and a pipe sleeve. A rotating sleeve is rotatably fitted onto the outer periphery of the pipe joint. In use, a first sealing component is first applied to the inner wall of the inner step. Then, guided by a guide component, the pipe joint is inserted into the pipe sleeve. When inserted to a certain position, the inner periphery of the rotating sleeve contacts the outer periphery of the fixed sleeve. Rotating the rotating sleeve, under the action of the connecting component, drives the pipe joint to continue moving into the pipe sleeve, improving installation efficiency. When the pipe joint moves to a suitable position within the pipe sleeve, the first sealing component adheres to the inner wall of the step groove, providing a first layer of sealing. Simultaneously, the end of the pipe joint presses against a second sealing component, providing a second layer of sealing. As the pipe joint moves, it drives a third sealing component to move synchronously, achieving a third layer of sealing.

[0004] The aforementioned utility model relies solely on the threaded connection during connection, but under conditions of vibration, impact, or pressure fluctuations, the threads may loosen or deform, leading to unstable connection, stripping, sealing failure, leakage, or equipment malfunction. Therefore, there is a need to provide a connection that can reinforce the sealing sleeve and improve the stability of the pipeline connection. Utility Model Content

[0005] The purpose of this utility model is to provide a battery liquid-cooled flexible connection sealing sleeve to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a battery liquid-cooled flexible connection sealing sleeve, comprising:

[0007] A pipe fitting and a rotating sleeve, wherein the rotating sleeve is fixed to one side of the pipe fitting;

[0008] The reinforcing component includes a fixed frame, a sliding hole, a connecting hole, and a movable column. There are two fixed frames, which are fixed on both sides of the outer surface of the rotating sleeve. The sliding hole is opened at the center of one side of the outer surface of the fixed frame, and the connecting hole is opened on the outer surface of the rotating sleeve. The sliding hole and the connecting hole are directly opposite each other. The movable column slides through the sliding hole and the connecting hole.

[0009] Furthermore, a sleeve is provided on the outer side of the pipe joint, and a fixing sleeve is fixed on one side of the sleeve.

[0010] Furthermore, a baffle is fixed to the middle of the outer surface of the movable column, and the end of the movable column extends into the rotating sleeve.

[0011] Furthermore, a first spring is fixed to one side of the baffle, and the first spring is located inside the fixed frame.

[0012] Furthermore, an annular groove is provided on the rear side of the outer surface of the fixed sleeve, and the end of the movable column is inserted into the annular groove.

[0013] Furthermore, it also includes a connecting assembly, which includes a first connecting plate, a connecting shaft, a movable plate, a mounting hole, a second spring, and a retaining pin. The first connecting plate is fixed to one side of the rotating sleeve. There are two connecting shafts, which are respectively fixed to both sides of the first connecting plate. The movable plate rotates through the outer surface of the connecting shaft. The mounting hole is opened on both sides of the end of the movable plate.

[0015] This utility model has the following beneficial effects:

[0016] This utility model includes a pipe connector, a pipe sleeve, a rotating sleeve, a fixed sleeve, and a reinforcing assembly. During connection, the movable column is pulled to both sides, simultaneously causing the baffle to move outwards. Under the limitation of the fixed frame, the baffle compresses the first spring, causing the end of the movable column to exit the connection hole. Then, the pipe connector is inserted into the pipe sleeve. When inserted to a certain position, the inner wall of the rotating sleeve contacts the outer wall of the fixed sleeve. Rotating the rotating sleeve, under the threaded connection of the internal and external threads, drives the pipe connector to continue moving into the pipe sleeve. When the fixed sleeve is completely submerged in the rotating sleeve, the first spring quickly recovers its deformation under its elastic force. The first spring causes the baffle to move towards the center, causing the end of the movable column to engage in the annular groove, firmly connecting the pipe connector and the pipe sleeve. Under the elastic force of the first spring, the end of the movable column automatically engages in the annular groove, forming a mechanical self-locking structure, ensuring a secure connection between the pipe connector and the pipe sleeve and preventing loosening.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a battery liquid-cooled flexible connection sealing sleeve, comprising:

[0029] Pipe fitting 11 and rotating sleeve 13, rotating sleeve 13 is fixed on one side of pipe fitting 11, pipe sleeve 12 is provided on the outer side of pipe fitting 11, and a fixing sleeve 14 is fixed on one side of pipe sleeve 12.

[0030] The pipe fitting 11 is the core component of the connection system, used to connect the hoses. By rotating the rotating sleeve 13, the pipe fitting 11 can be moved inside the pipe sleeve 12 to achieve connection or disconnection. The pipe sleeve 12 is a fixing component used to accommodate the pipe fitting 11 and provide support. The fixing sleeve 14 is fixed on one side of the pipe sleeve 12 and is used to form a threaded connection with the rotating sleeve 13.

[0031] The reinforcement component includes a fixed frame 21, a sliding hole 22, a connecting hole 23, and a movable column 24. There are two fixed frames 21, which are fixed on both sides of the outer surface of the rotating sleeve 13 respectively. The sliding hole 22 is opened at the center of one side of the outer surface of the fixed frame 21, and the connecting hole 23 is opened on the outer surface of the rotating sleeve 13. The sliding hole 22 and the connecting hole 23 are directly opposite each other. The movable column 24 slides through the sliding hole 22 and the connecting hole 23.

[0032] The fixed frame 21 provides support and limit for the movable column 24, the sliding hole 22 is used for the sliding of the movable column 24, the connecting hole 23 corresponds to the sliding hole 22 and is used for the movable column 24 to pass through, and the movable column 24 is used for locking or unlocking the connection.

[0033] A baffle 25 is fixed in the middle of the outer surface of the movable column 24, and the end of the movable column 24 extends into the rotating sleeve 13. A first spring 26 is fixed on one side of the baffle 25, and the first spring 26 is located inside the fixed frame 21. An annular groove 27 is opened on the rear side of the outer surface of the fixed sleeve 14, and the end of the movable column 24 is inserted into the annular groove 27.

[0034] The baffle 25 is used to limit the range of movement of the movable column 24, the first spring 26 is located inside the fixed frame 21 to provide elastic force, and the annular groove 27 is used to accommodate the end of the movable column 24.

[0035] Working principle:

[0036] During connection, the movable column 24 is pulled to both sides, and the movable column 24 simultaneously drives the baffle 25 to move outward. Under the limit of the fixed frame 21, the baffle 25 compresses the first spring 26, causing the end of the movable column 24 to exit from the connection hole 23. Then, the pipe connector 11 is inserted into the pipe sleeve 12. When it is inserted to a certain position, the inner wall of the rotating sleeve 13 contacts the outer wall of the fixed sleeve 14. Then, the rotating sleeve 13 is rotated, and under the threaded connection of the internal thread groove and the external thread, the pipe connector 11 continues to move into the pipe sleeve 12. When the fixed sleeve 14 is completely submerged in the rotating sleeve 13, under the elastic force of the first spring 26, the first spring 26 will quickly recover its deformation. The first spring 26 drives the baffle 25 to move towards the middle, so that the end of the movable column 24 is stuck into the annular groove 27, and the pipe connector 11 is firmly connected to the pipe sleeve 12.

[0037] In this step, under the elastic force of the first spring 26, the end of the movable column 24 automatically engages with the annular groove 27, forming a mechanical self-locking structure to ensure a firm connection between the pipe joint 11 and the pipe sleeve 12 and prevent loosening.

[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The connecting assembly includes a first connecting plate 31, a connecting shaft 32, a movable plate 33, a mounting hole 331, a second spring 34, and a locking post 35. The first connecting plate 31 is fixed to one side of the rotating sleeve 13. There are two connecting shafts 32, which are respectively fixed to both sides of the first connecting plate 31. The movable plate 33 rotates through the outer surface of the connecting shaft 32. The mounting hole 331 is opened on both sides of the end of the movable plate 33. The second spring 34 is fixed inside the mounting hole 331. The locking post 35 is fixed to one end of the second spring 34. The second connecting plate 36 is fixed to one side of the fixed sleeve 14. The second connecting plate 36 has mounting grooves 37 on both sides. The mounting grooves 37 have locking slots 38 inside. The end of the locking post 35 extends into the locking slot 38.

[0040] The first connecting plate 31 is the core component of the connecting assembly, used to connect the rotating sleeve 13 and the movable plate 33. The connecting shaft 32 is the connecting component between the first connecting plate 31 and the movable plate 33. The movable plate 33 is the movable component of the connecting assembly, used to lock and unlock the locking pin 35. The mounting hole 331 is the hole at the end of the movable plate 33, used to install the second spring 34 and the locking pin 35. The second spring 34 is used to provide elastic force. The slot 38 is used to accommodate the locking pin 35.

[0041] Working principle:

[0042] After the pipe joint 11 is connected to the pipe sleeve 12, rotate the movable plate 33 and press the locking post 35 inward so that the locking post 35 is inserted into the mounting hole 331. Then, the movable plate 33 is inserted into the mounting groove 37. When the locking post 35 is aligned with the groove 38, the second spring 34 quickly returns to its original shape. The second spring 34 drives the locking post 35 to be inserted into the groove 38, connecting the first connecting plate 31 and the second connecting plate 36 together.

[0043] This step, with its dual protection of mechanical self-locking and spring reset, ensures high connection reliability, reduces the likelihood of failure due to operational errors or environmental factors, lowers the failure rate, and improves the overall safety of the system.
