Description

Technical Field

[0001] The present invention belongs to the technical field of connection devices, and in particular relates to a connection socket and a fluid connector. Background Art

[0002] A fluid connector is a piping device that plays a crucial role in fluid and gas transportation. It enables quick connection and disconnection of pipelines, ensuring a tight seal in all conditions. It's quick to operate and easy to maintain. As a crucial component for connecting high-pressure fluid pipelines and controlling the flow of fluids, the plug and socket connections of fluid connectors are particularly crucial.

[0003] In the prior art, the connection between the fluid connector socket and the plug is mostly achieved by a clamping connection, such as the connection socket and fluid connector disclosed in publication number CN118867738A. The disclosed connection socket can be used with plugs of various specifications of the same model, eliminating the need to replace the socket for different plugs. This saves a significant amount of testing time during testing, makes operation more convenient, and reduces the overall cost of the testing equipment. In addition, the connection between the connection socket and the plug is more convenient to install and disassemble, has a good sealing effect, and provides a more stable fit. However, in the aforementioned patent, the movement of the clamping claw within the installation space is translational, resulting in a larger working stroke and a larger installation space. Therefore, how to adapt the connection socket to a larger cross-sectional size while ensuring that the cross-sectional size of the connection socket remains unchanged has become an urgent problem that needs to be solved in the industry.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figure 1-Figure 7 As shown, a connection socket includes:

[0033] Operation shell 100;

[0034] The connecting shell 200 is located inside the operating shell 100. The operating shell 100 can move linearly along the axis of the connecting shell 200. A connecting cavity 201 is provided inside the connecting shell 200. A gap is provided between the operating shell 100 and the connecting shell 200 to form the installation cavity 101.

[0035] At least two claw portions 300 are disposed within the mounting cavity 101 , each claw portion 300 including a claw 301 . The multiple claw portions 300 are disposed around the side of the connecting housing 200 . The claw portions 300 are rotatable relative to the connecting housing 200 . The claws 301 are provided with an actuator, and the operating housing 100 is provided with an operating portion 105 .

[0036] In the first working state, the claws 301 on the claw portion 300 are all extended into the connecting cavity 201, and no power is transmitted between the execution portion and the operating portion 105;

[0037] In the second working state, the execution portion is connected to the operating portion 105 , and the claw 301 on the claw portion 300 is retracted into the installation cavity 101 .

[0038] In this embodiment, the claw portion 300 and the connecting shell 200 are rotationally connected, so that the movement mode of the claw 301 is changed from the existing translational type to the rotational type in this application, and the working stroke of the claw 301 in the installation cavity 101 is shorter, thereby reducing the space thickness required for the installation cavity 101. Then, when the operating shell 100 remains unchanged and the shell wall thickness of the connecting shell 200 remains unchanged, the cross-sectional size of the connecting cavity 201 in the connecting shell 200 is larger, thereby realizing connection with the connecting joint 500 with a larger cross-sectional size.

[0039] Preferably, the claw portion 300 also includes a tilting rod 302 arranged in the installation cavity 101, the first end of the tilting rod 302 is fixed to the claw 301, the execution part is arranged at the second end of the tilting rod 302, and a tilting portion 303 is provided on the tilting rod 302, and the tilting rod 302 can rotate around the tilting portion 303.

[0040] Specifically, the execution part includes an execution rod 304 fixedly arranged at the second end of the tilting rod 302, the first end of the execution rod 304 is fixed to the second end of the tilting rod 302, and the second end of the execution rod 304 is tilted toward the axial direction away from the connecting shell 200; wherein, in the first working state, the operating part 105 is not in contact with the execution part; in the second working state, the operating part 105 is in contact with the execution part and squeezes the second end of the execution rod 304 to cause the second end of the execution rod 304 to rotate.

[0041] In this embodiment, in the first working state, the tilting rod 302 is connected to the outer wall of the connecting shell 200, and the executing rod 304 is tilted and does not contact the connecting shell 200, and a gap is left between the executing rod 304 and the connecting shell 200 to reserve rotation space for the executing rod 304, and a tilting portion 303 is formed at the connection between the executing rod 304 and the tilting rod 302. As the operating shell 100 moves relative to the connecting shell 200 (the tilting rod 302 is toward the direction of the executing rod 304), the operating part 105 on the operating shell 100 gradually approaches the executing rod 304 and abuts against the executing rod 304. As the operating shell 100 continues to move, the operating part 105 squeezes the executing rod 304, causing it to rotate around the tilting portion 303, and the claw 301 retracts into the installation cavity 101, thereby disconnecting the connection with the connecting joint 500.

[0042] It is worth mentioning that the operating portion 105 includes an operating block fixedly arranged on the inner shell wall of the operating shell 100 .

[0043] Further preferably, a limiting groove 202 is provided around the side surface of the connecting shell 200 , an elastic ring member 203 is provided in the limiting groove 202 , and the claw portion 300 is connected to the elastic ring member 203 .

[0044] In this embodiment, in order to ensure that the relative position between the claw 301 and the connecting shell 200 does not change during the rotation of the claw 301, a limiting groove 202 is provided on the side of the connecting shell 200, and an installation groove 204 is also provided on the outer shell wall of the connecting shell 200. The number of the installation grooves 204 is equal to the number of the claw parts 300. The installation groove 204 passes through the limiting groove 202, dividing the limiting groove 202 into multiple independent sections, and the tilting rod 302 is installed in the installation groove 204. At the same time, the elastic ring 203 in the limiting groove 202 is also sleeved on the tilting rod 302, so that the tilting rod 302 will not separate from the installation groove 204 after being tilted.

[0045] Specifically, a groove 305 is provided on the tilting rod 302 , and the elastic ring member 203 is sleeved in the groove 305 to achieve connection with the tilting rod 302 .

[0046] It is worth mentioning that the elastic ring member 203 can be selected from one of an elastic rubber ring, a retractable rope, or a tension spring connected end to end to form a ring.

[0047] Further preferably, the connecting shell 200 is provided with engaging notches 205 , the number of the engaging notches 205 is equal to the number of the clamping claws 301 , and the clamping claws 301 on the clamping claw portion 300 pass through the engaging notches 205 .

[0048] In this embodiment, the clamping notch 205 on the connecting shell 200 is connected to the mounting groove 204, the clamping claw 301 on the clamping claw portion 300 passes through the clamping notch 205, and the tilting rod 302 on the clamping claw 301 is located in the mounting groove 204. In the first working state, the clamping claw 301 passes through the clamping notch 205 and extends into the connecting shell 200, and in the second working state, the clamping claw 301 retracts into the mounting cavity 101; at the same time, the setting of the clamping notch 205 enables the clamping notch 205 to limit the clamping claw 301 in the first working state, preventing the clamping claw 301 from moving along the axial direction of the connecting shell 200.

[0049] Further preferably, a limiting portion is provided on the connecting shell 200, and an abutting portion is provided on the operating shell 100, wherein in the second working state, the limiting portion and the abutting portion are in abutting connection.

[0050] Specifically, the abutting portion includes an abutting wall 102 arranged on the operating shell 100, and the limiting portion includes a limiting ring 206 located on the outer shell wall of the connecting shell 200, wherein, in the first working state, a gap is left between the abutting wall 102 and the limiting ring 206, and the abutting wall 102 moves synchronously with the operating shell 100 relative to the connecting shell 200, and the abutting wall 102 approaches the limiting ring 206 until the abutting wall 102 abuts against the limiting ring 206, and the relative movement between the operating shell 100 and the connecting shell 200 is restricted to prevent the operating shell 100 from being separated from the connecting shell 200, and at this time, the claw 301 also retracts into the mounting cavity 101.

[0051] Specifically, the connecting shell 200 includes a main shell 400 and a tail interface 401 detachably connected to the main shell 400. A stop ring 402 is provided on the main shell 400, and a movable space is formed between the stop ring 402 and the tail interface 401. A limit ring 103 is provided on the operating shell 100, and the limit ring 103 is located in the movable space. In the first working state, the limit ring 103 is in contact with the stop ring 402.

[0052] In this embodiment, the threaded connection between the main shell 400 and the tail interface 401 realizes a detachable connection, and the detachable connection between the main shell 400 and the tail interface 401 facilitates the assembly and molding of the entire connecting socket; the presence of the limiting portion on the connecting shell 200 and the abutting portion on the operating shell 100 can limit the movement stroke of the operating shell 100 relative to the connecting shell 200 when the connecting socket switches from the first working state to the second working state, and the presence of the limiting ring 103 and the stop ring 402 can limit the movement stroke of the operating shell 100 relative to the connecting shell 200 when the connecting socket switches from the second working state to the first working state.

[0053] Further preferably, a first elastic member 104 is provided in the activity space, and the two ends of the first elastic member 104 are respectively connected to the end of the limit ring 103 and the tail interface 401. The setting of the first elastic member 104 enables the operating shell 100 to move relative to the connecting shell 200. After switching from the first working state to the second working state, the operating shell 100 is released. Under the elastic force of the first elastic member 104, the operating shell 100 can be automatically reset, and the connecting socket also switches back to the first working state.

[0054] Preferably, a valve ring 403 is provided in the main shell 400, and the valve ring 403 can move along the axial direction of the main shell 400. An anti-slip ring is provided on the inner shell wall of the main shell 400, and a moving space is formed between the anti-slip ring and the tail interface 401. The valve ring 403 is located in the moving space, and a second elastic member 404 is provided in the moving space. The two ends of the second elastic member 404 are respectively connected to the tail interface 401 and the valve ring 403.

[0055] In this embodiment, the provision of the second elastic member 404 allows the valve ring 403 to have a certain elastic range of motion, which can adapt to connecting joints 500 of different lengths, thereby making the connection socket in this application more widely applicable.

[0056] like Figure 8 As shown, a fluid connector includes the connection socket as described above and a connection joint 500 . When the connection joint 500 is inserted into the connection shell 200 , the claw 301 is clamped in the clamping groove on the connection joint 500 .

[0057] It is worth mentioning that a locking column is provided on the connecting joint 500 and a locking groove is provided on the connecting shell 200. When the connecting joint 500 is inserted into the connecting shell 200, the locking column is inserted into the locking groove to prevent the connecting joint 500 and the connecting shell 200 from rotating relative to each other.
