Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a quick-connect tee. Background Technology

[0002] The energy storage fire suppression system is a crucial component for ensuring the safe operation of energy storage facilities. It mainly consists of a fire alarm system, a fire-fighting linkage system, and a fire extinguishing system. When fire suppression is carried out on individual energy storage battery packs, a piping network is needed to connect the packs to the fire cylinders. In the three-level piping construction of this system, quick-connect tees are commonly used to connect the pipes.

[0003] Traditional quick-connect tees use locking elements to lock or unlock the pipe fitting. Patent announcement number CN211779573U discloses a quick-connect self-locking connector, which describes a connector body with an inner sleeve inside one end, into which a gripping cap is inserted. The connector body and inner sleeve are mutually self-locked by a snap-fit ​​or riveting method. When unlocking is required, the gripping cap needs to be pressed towards the body. However, due to the small contact area between the gripping cap and the pipe fitting, it is difficult to form an effective point of force. Furthermore, the connection between the pipe fitting and the quick-connect tee is tight, making it difficult to apply force during operation, and the entire process is quite strenuous. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect tee to solve the technical problems in the prior art, which can easily separate the pipe fitting from the quick-connect tee.

[0005] This utility model provides a quick-connect tee, comprising: a tube body, a locking component, and an auxiliary unit, wherein:

[0006] The tube body has an opening;

[0007] The locking member is disposed at the opening, with a first end extending to the outside of the tube body and a second end housed in the inner cavity of the tube body. The locking member has a first state and a second state.

[0008] The auxiliary unit includes a transmission component and an elastic return component. The elastic return component is disposed at the end of the tube body away from the opening. One end of the transmission component is connected to the elastic return component, and the other end is connected to the first end of the locking component. There is a preset angle between the transmission component and the first end of the locking component. Driving the transmission component can change the size of the preset angle to make the elastic return component extend or retract. The locking component switches between a first state and a second state.

[0009] In the quick-connect tee described above, preferably, a protrusion is provided on the outer wall surface of the tube body, and the elastic return member abuts against the side of the protrusion away from the opening. The elastic return member moves along the axial direction of the tube body. When the transmission member is driven to change the preset angle, the elastic return member presses against the protrusion, and the first end of the locking member approaches the opening.

[0010] In the quick-connect tee described above, preferably, the transmission component includes a pressure plate, a first connecting member, and a second connecting member. One end of the first connecting member is movably connected to the side of the elastic restoring member opposite to the protrusion, and the other end of the first connecting member is movably connected to the first end of the pressure plate. One end of the second connecting member is movably connected to the outer wall surface of the tube body, and the other end of the second connecting member is movably connected to the middle part of the first connecting member. The second end of the pressure plate is movably connected to the first end of the locking member.

[0011] In the quick-connect tee as described above, preferably, the elastic return element includes a spring and a sliding sleeve, the sliding sleeve being sleeved on the outer wall of the tube body, and the side of the spring opposite to the protrusion being connected to the sliding sleeve.

[0012] In the quick-connect tee described above, preferably, the auxiliary unit is symmetrically arranged on both sides of the tube body along the axis of the tube body.

[0013] Compared with the prior art, this utility model sets an auxiliary unit between the locking member and the outer wall of the pipe body. The auxiliary unit drives the locking member to approach the opening, thereby unlocking it from the pipe body. Compared with the traditional method of directly operating the locking member, the auxiliary unit increases the area of ​​the force point, making it easier and more convenient for the operator to exert force. It can transmit force to the locking member more efficiently, thereby quickly unlocking the pipe body from the pipe body and saving operation time. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] See Figure 1 As shown in Figure 5, this utility model provides a quick-connect tee, including a tube body 10, a locking member 20 for locking or releasing the tube body, and an auxiliary unit 30, wherein:

[0025] The tube body 10 has an opening 11, and a locking member 20 is disposed in the opening 11. The first end of the locking member 20 extends to the outside of the tube body 10, and the second end of the locking member 20 is received within the inner cavity of the tube body 10. The locking member 20 has a first state and a second state. When the locking member 20 is in the first state, the first end of the locking member 20 is away from the opening 11; when the locking member 20 is in the second state, the first end of the locking member 20 is close to the opening 11. In the embodiments provided in this application, the structure of the locking member 20 is not limited; it can be a quick-connect self-locking connector mentioned in the background art, or other self-locking connectors. The locking can be released by pressing the locking member 20. The tube body 10 can be a tee pipe or a two-way pipe, etc. The first state of the locking member 20 is the state of locking the tube, and the second state of the locking member 20 is the state of unlocking the tube.

[0026] The existing locking member 20 has a small contact area at its first end, making it difficult to apply force when pressing it. Furthermore, the locking member 20 is tightly connected to the pipe, resulting in high friction and making removal inconvenient. Therefore, in this application, the auxiliary unit 30 includes a transmission member 31 and an elastic return member 32. The elastic return member 32 is located at the end of the pipe body 10 away from the opening 11. One end of the transmission member 31 is connected to the elastic return member 32, and the other end is connected to the first end of the locking member 20. A preset angle exists between the transmission member 31 and the first end of the locking member 20. Driving the transmission member 31 changes the size of the preset angle, causing the elastic return member 32 to extend or retract, and the locking member 20 to switch between a first state and a second state. The auxiliary unit 30 is located on the outer wall of the pipe body 10 and does not contact the pipe, reducing friction between them. Driving the auxiliary unit 30 shifts the point of force application from the first end of the locking member 20 to the auxiliary unit 30, increasing the point of force application and facilitating force application.

[0027] In one possible implementation, see [link to implementation details]. Figure 1 -2 and Figure 4 As shown, the auxiliary units 30 are symmetrically arranged on both sides of the tube body 10 along the axis of the tube body 10. At least one auxiliary unit 30 is provided, and as a preferred method, two auxiliary units 30 are symmetrically arranged on the outer wall of the tube body 10. The auxiliary units 30 are driven at the same time to control the locking member 20. The auxiliary units 30 on both sides can evenly share the load, so that the force transmitted to the first end of the locking member 20 is more balanced.

[0028] See Figure 2 As shown in Figure 5, a protrusion 12 is provided on the outer wall surface of the tube body 10. An elastic recovery member 32 abuts against the side of the protrusion 12 opposite to the opening 11. One end of the transmission member 31 is connected to the side of the elastic recovery member 32 opposite to the protrusion 12, and the other end of the transmission member 31 is connected to the first end of the locking member 20. The elastic recovery member 32 moves along the axial direction of the tube body 10. When the transmission member 31 is driven to change the preset angle, the elastic recovery member 32 presses against the protrusion 12, and the first end of the locking member 20 approaches the opening 11. In the embodiments provided in this application, the protrusion 12 can be a boss structure, the elastic recovery member 32 abuts against the boss, and the elastic recovery member 32 and the locking member 20 are connected by the transmission member 31. When the tube is not inserted, the elastic recovery member 32 is in a natural state, and the transmission member 31, the elastic recovery member 32 and the locking member 20 can be in a balanced state. When the locking member 20 is in the first state, the locking member 20 locks the tube, and the first end of the locking member 20 will move away from the opening 11. When the transmission member 31 is driven to increase the preset angle, the elastic recovery member 32 presses towards the boss side, so that the first end of the locking member 20 can move closer to the opening 11. When the first end of the locking member 20 moves closer to the opening 11, the locking member is in the second state, that is, the locking of the tube is released.

[0029] See Figure 3 As shown in Figure 4, the transmission component 31 includes a pressure plate 310, a first connecting member 311, and a second connecting member 312. One end of the first connecting member 311 is movably connected to the side of the elastic recovery member 32 opposite to the protrusion 12, and the other end of the first connecting member 311 is movably connected to the first end of the pressure plate 310. One end of the second connecting member 312 is movably connected to the outer wall surface of the tube body 10, and the other end of the second connecting member is movably connected to the middle part of the first connecting member 311. The second end of the pressure plate 310 is movably connected to the first end of the locking member 20. In the embodiments provided in this application, the first connector 311 and the second connector 312 raise one end of the pressure plate 310 to a certain height, so that a preset angle is formed between the pressure plate 310 and the first end of the locking member 20. When it is necessary to change the locking member 20 from the first state to the second state, the distance between the first connector 311 and the second connector 312 can be shortened by raising the pressure plate 310. The elastic return member 32 presses against the protrusion 12 side, so that the locking member 20 will move closer to the opening 11, and the locking member 20 changes from the first state to the second state.

[0030] The elastic return member 32 not only increases the force balance and provides tension to the transmission member 31, but also ensures that the locking member 20 can be reset. After the tube is unlocked, the pressure plate 310 is released, and the elastic return member 32 is no longer under force. It will move away from the protrusion 12 until it returns to its natural state. The elastic return member 32 is reset, so the transmission member 31 can push the first end of the locking member 20 away from the opening 11. Therefore, even if the locking member 20 cannot automatically spring back, the auxiliary unit 30 can drive the locking member 20 to reset.

[0031] In one possible implementation, see [link to implementation details]. Figure 3 As shown in Figure 4, the first connecting member 311 is a plate-like structure, and the second connecting member 312 is a linkage structure. The second connecting member 312 is connected to the side of the protrusion 12 opposite to the elastic return member 32. The first connecting member 311, the second connecting member 312, and the pressure plate 310 are connected to form a stable linkage mechanism. This multi-link structure can effectively distribute and transmit force, making the force on each component more uniform during operation. The movable connection can be a rotating connection or a hinge. When no force is applied to the pipe, the elastic return member 32 can automatically rebound and drive the transmission member 31 to reset. This automatic reset function ensures that the pipe is always in a reliable locked state during normal use.

[0032] To facilitate the operation of the pressure plate 310, the pressure plate 310 can be extended appropriately. Specifically, the first connecting piece 311 is connected to the rear of the pressure plate 310. By lifting the extended end of the pressure plate 310, force can be easily applied to the auxiliary unit 30.

[0033] In another implementation, see Figure 3 As shown in Figure 5, the elastic recovery member 32 includes a spring 320 and a sliding sleeve 321. The sliding sleeve 321 is sleeved on the outer wall surface of the tube body 10, and the side of the spring 320 facing away from the protrusion 12 is connected to the sliding sleeve 321. The sliding sleeve 321 can move along the axial direction of the tube body 10. In this embodiment, the sliding sleeve 321 is connected to the spring 320, which can guide and position the spring 320, making it less likely for the spring 320 to shift or shake during compression and rebound. The sliding sleeve 321 also facilitates the connection between the first connecting member 311 and the elastic recovery member 32.

[0034] Based on the above embodiments, the working process of this utility model is as follows:

[0035] When the locking member 20 changes from the first state to the second state, the pressure plate 310 is lifted, the preset angle increases, the first connecting member 311 moves closer to the second connecting member 312, the sliding sleeve 321 drives the spring 320 to press towards the protrusion 12, and at the same time the pressure plate 310 drives the first end of the locking member 20 to move towards the opening 11 of the tube body 10, the locking member 20 changes from the first state to the second state, at this time, the locking member 20 releases the locking of the tube;

[0036] When the tube is pulled out, the locking member 20 returns to its original position, and the spring 320 is no longer under force and moves away from the protrusion 12. The first connecting member 311 moves away from the second connecting member 312, thereby driving the pressure plate 310 to move closer to the axis of the tube body 10. The preset angle becomes smaller. At this time, the pressure plate 310 will also push the locking member 20 away from the opening 11.

[0037] In this application, the auxiliary unit 30 can be driven to change the locking member 20 from the second state to the first state in the initial state. After the pipe is inserted, no force is applied to the auxiliary unit 30, and the locking member 20 automatically changes to the first state to lock the pipe.

[0038] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
