Description

Technical Field

[0001] This utility model relates to a fluid connector with a resilient locking plate. Background Technology

[0002] Ball valve connectors are commonly used fluid connectors in industrial production. Traditional ball valve connectors feature a locking device on the handle. This locking device moves synchronously with the handle, and two positioning grooves correspond to the locking device and are located on the valve body. When the locking device moves to the first or second position, it engages with the corresponding positioning groove, placing the ball valve in either the fully open or fully closed state. This locking device on the handle prevents accidental handle contact and potential misoperation of the ball valve.

[0003] The aforementioned device can lock the handle to prevent accidental activation. However, even when the two ball valves are not connected, personnel can still press the handle to unlock it, which increases the risk of accidental activation and could lead to fluid leakage. Summary of the Invention

[0004] The purpose of this utility model is to provide a fluid connector with an elastic locking plate, including a valve body, a valve ball assembly and a handle. The valve body has a snap-fit ​​part and an interface groove on its mating surface. The valve ball assembly is rotatably disposed inside the valve body. The opening and closing of the valve body is controlled by the rotation of the valve ball assembly. The handle is disposed on the valve ball assembly and has a meshing groove. It also includes a locking component.

[0005] The locking assembly includes a positioning rod, an elastic locking plate, and a positioning hole. The opening of the positioning hole is located on the mating surface. The positioning rod is slidably connected to the valve body and is disposed on the valve body. The positioning rod has an engaging portion located on the side of the positioning rod near the engaging groove. The engaging portion engages with the engaging groove. The elastic locking plate is movably disposed inside the valve body. The elastic locking plate includes a mounting plate, a locking plate, and an elastic connecting sleeve. The mounting plate is fixedly connected to the valve body. The upper end of the locking plate is connected to the mounting plate through the elastic connecting sleeve. The lower end of the locking plate extends into the interface groove. The positioning rod is provided with a locking groove that engages with the locking plate.

[0006] Preferably, one end of the positioning rod is provided with an engaging part that engages with the engaging groove of the handle, and the other end of the positioning rod is provided with a plug that matches the positioning hole.

[0007] Preferably, the cross-section of the elastic locking piece is inverted V-shaped, and the mounting piece, locking piece, and elastic connecting tube of the elastic locking piece are integrally formed.

[0008] Preferably, the fluid connector further includes a sealing ring, which is fixedly connected to the valve body and located on the mating surface of the valve body.

[0009] Preferably, the valve ball assembly includes a valve ball and a valve stem, the valve ball being rotatably mounted inside the valve body; the valve stem is fixedly connected to the valve ball and to the handle, and is located at the top of the valve ball; the valve ball has a fluid passage that extends through the valve ball.

[0010] The advantages and beneficial effects of this utility model are as follows: It provides a fluid connector with a spring locking plate. When the two ball valves are not connected, the locking plate is engaged in the locking groove of the positioning rod, thereby locking the positioning rod with the elastic locking plate. The meshing part of the positioning rod meshes with the meshing groove of the handle, and the positioning rod locks the handle. Thus, when the two valve bodies are not connected, the risk of accidental handle contact is avoided, and fluid leakage is prevented. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows:

[0017] like Figures 1 to 4 As shown, a fluid connector with a resilient locking mechanism includes a valve body 1, a valve ball assembly 2, and a handle 3. The valve body 1 has a snap-fit ​​portion 41 and an interface groove 42 on its mating surface 4. The valve ball assembly 2 is rotatably disposed inside the valve body 1, and the opening and closing of the valve body 1 is controlled by the rotation of the valve ball assembly 2. The handle 3 is disposed on the valve ball assembly 2 and has an engagement groove 31. The connector also includes a locking component 5.

[0018] The locking assembly 5 includes a positioning rod 51, an elastic locking piece 52, and a positioning hole 53. The opening of the positioning hole 53 is disposed on the mating surface 4. The positioning rod 51 is slidably connected to the valve body 1 and disposed on the valve body 1. The positioning rod 51 has an engaging part 511, which is disposed on the side of the positioning rod 51 near the engaging groove 31. The engaging part 511 engages with the engaging groove 31. The elastic locking piece 52 is movably disposed inside the valve body 1. The elastic locking piece 52 includes a mounting piece 521, a locking piece 522, and an elastic connecting tube 523. The mounting piece 521 is fixedly connected to the valve body 1. The upper end of the locking piece 522 is connected to the mounting piece 521 through the elastic connecting tube 523. The lower end of the locking piece 522 extends into the interface groove 42. The positioning rod 51 is provided with a locking groove 513 that engages with the locking piece 522.

[0019] Preferably, one end of the positioning rod 51 is provided with an engagement part 511, which engages with the engagement groove 31 of the handle 3, and the other end of the positioning rod 51 is provided with a plug 512, which matches the positioning hole 53.

[0020] Preferably, the cross-section of the elastic locking piece 52 is inverted V-shaped, and the mounting piece 521, locking piece 522 and elastic connecting tube 523 of the elastic locking piece 52 are integrally formed.

[0021] Preferably, the fluid connector further includes a sealing ring 6, which is fixedly connected to the valve body 1 and located on the mating surface 4 of the valve body 1.

[0022] Preferably, the valve ball assembly 2 includes a valve ball 21 and a valve stem 22, the valve ball 21 being rotatably mounted inside the valve body 1; the valve stem 22 being fixedly connected to the valve ball 21 and the valve stem 22 being fixedly connected to the handle 3 and located at the top of the valve ball 21; the valve ball 21 having a fluid passage 23 that penetrates the valve ball 21.

[0023] When in use, with the two ball valves 1 not connected, the handle 3 is in the closed position, and the positioning rod 51 is retracted into the valve body 1. The elastic locking plate 52 is fixed inside the valve body 1 by the mounting plate 521, and the locking plate 522 is engaged in the locking groove 513 of the positioning rod 51, thereby locking the positioning rod 51. Since the engaging part 511 of the positioning rod 51 engages with the engaging groove 31 of the handle 3, the handle 3 is locked, so that when the valve body 1 is not connected, the handle 3 is in the closed position and locked, preventing fluid leakage.

[0024] When two valve bodies 1 are connected, the snap-fit ​​part 41 of one valve body 1 rotates and snaps into the interface groove 42 of the other valve body 1. During the rotation, the snap-fit ​​part 41 pushes the bottom of the locking plate in the other valve body 1, causing the locking plate to move towards the mounting plate with the elastic connecting cylinder as the center. The elastic connecting cylinder deforms elastically, and the locking plate disengages from the locking groove of the positioning rod. At this time, the positioning rod 51 is released from the locking state, and the handle 3 can be rotated. By rotating the handle 3, the valve stem 22 and the valve ball 21 are rotated, thereby opening the valve body 1. During the rotation of the handle 3, the positioning rod 51 is driven to move through the engagement groove 31 and the engagement part 511, so that the positioning rod 51 extends into the positioning hole 53 on the other valve body 1 to position the two valve bodies 1.

[0025] When the two valve bodies 1 are not connected in place, the positioning hole 53 on one valve body 1 is not aligned with the positioning rod 51 on the other valve body 1. At this time, the positioning rod 51 cannot be inserted into the positioning hole 53, which prevents the handle 3, valve stem 22 and valve ball 21 from rotating, thus avoiding fluid leakage caused by the valve body 1 being opened even when the two valve bodies 1 are not connected in place.

[0026] Finally, when valve body 1 is not closed or not fully closed (i.e., handle 3 is not in the closed position), the positioning rod 51 is not fully retracted into valve body 1, causing the positioning rod 51 to be fully or partially inserted into the positioning hole 53 on another valve body 1. At this time, the two valve bodies 1 cannot rotate. Only after valve body 1 is fully closed can the two valve bodies 1 rotate to disconnect the connection, thus avoiding fluid leakage caused by disconnection when valve body 1 is not closed or not fully closed.

[0027] This utility model discloses a fluid connector with an elastic locking plate, which can not only lock the handle 3 when the two valve bodies 1 are not connected, but also prevent the handle 3 from being opened when the two valve bodies 1 are not connected in place. It can also prevent the connection between the two valve bodies 1 from being disconnected when the handle 3 is not fully closed, thereby greatly reducing the risk of fluid leakage.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
