Description

A quick-release clamp for pressure gauge connectors Technical Field

[0001] This application relates to the field of pressure gauge connector mounting and dismounting clamps, and in particular to a quick mounting and dismounting clamp for pressure gauge connectors. Background Technology

[0002] A pressure gauge is an instrument used to measure the pressure of gases or liquids, and it is widely used in industries, laboratories, and medical fields. In industrial production, pressure gauges are typically used to monitor pressure changes in various equipment and systems to ensure their normal operation.

[0003] Pressure gauges undergo a series of tests before leaving the factory, such as overpressure tests, to ensure product quality. Some tests require connecting the pressure gauge to a gas source. In related technologies, this is often achieved by adding a loading and unloading fixture to the gas source and then connecting the pressure gauge to the fixture.

[0004] Pressure gauges and clamps are often connected by threads. When connecting the pressure gauge to the clamp, workers often need to rotate the gauge 7-8 times, and the same applies when separating it. This results in high workload and low efficiency for workers when testing pressure gauges, and needs improvement. Summary of the Invention

[0005] In order to reduce the workload of staff when testing pressure gauges and improve work efficiency, this application provides a quick-release clamp for pressure gauge connectors.

[0006] The pressure gauge connector quick-release clamp provided in this application adopts the following technical solution:

[0007] A pressure gauge connector quick-release clamp includes a gauge connector connecting sleeve for connecting to a gas source and a locking assembly. The end face of the gauge connector connecting sleeve is provided with a connector cavity for communicating with the gas source. The connector cavity is used for inserting the end of the pressure gauge connector. The outer wall of the gauge connector connecting sleeve is provided with a locking hole communicating with the connector cavity.

[0008] The locking assembly includes a locking member and a locking ring rotatably sleeved on the gauge connector connecting sleeve. The length of the locking member along its sliding direction is greater than the depth of the locking hole. The two ends of the locking member are respectively used to abut against the inner wall of the locking ring and the pressure gauge connector. A clearance groove is provided on the inner wall of the locking ring.

[0009] When one end of the locking member abuts against the inner wall of the locking ring, the other end of the locking member extends into the connector cavity; when one end of the locking member is completely moved into the relief groove, the other end of the locking member is completely located in the locking hole.

[0010] By adopting the above technical solution, when using the quick-release fixture of this application, first connect the gauge connector sleeve and connect the connector cavity to the air source. A locking ring groove needs to be opened on the connector of the pressure gauge to be tested, corresponding to the end of the locking element, for the end of the locking element to be inserted. When testing the pressure gauge, first rotate the locking ring until the clearance groove aligns with the locking hole, then directly insert the pressure gauge connector into the connector cavity. Under the push of the pressure gauge connector, one end of the locking element completely moves into the locking hole, and the other end of the locking element inserts into the clearance groove. Next, rotate the locking ring to misalign the clearance groove with the locking hole. The inner wall of the locking ring presses against the locking element and pushes the locking element to move, so that the end of the locking element extends into the connector cavity and inserts into the locking ring groove on the pressure gauge connector, thus locking the pressure gauge connector. When the pressure gauge test is completed, reverse the locking ring to realign the clearance groove with the locking groove, at which point the pressure gauge connector can be removed from the connector cavity.

[0011] The pressure gauge is locked and unlocked by rotating the locking ring. The total number of rotations required for each locking and unlocking operation is no more than one. Compared with the connection between the fixture and the pressure gauge via threads, this design effectively reduces the labor intensity of the workers and greatly improves work efficiency.

[0012] Optionally, the connecting sleeve of the watch connector is provided with a sliding groove, and a locking block is connected to the locking ring. The locking block is slidably disposed in the sliding groove around the rotation axis of the locking ring. A locking elastic element is provided in the sliding groove. One of the groove walls of the sliding groove is a locking wall for abutting against the locking block. A locking elastic element is provided in the sliding groove for applying a force toward the locking wall to the locking block. When the locking block abuts against the locking wall, the clearance groove is misaligned with the locking hole.

[0013] By employing the above technical solution, when testing a pressure gauge, the pressure gauge connector is inserted into the connector cavity and the locking ring is rotated until the clearance groove aligns with the locking hole. At this point, the locking block moves with the locking ring to compress the locking elastic element. Driven by the pressure gauge connector, one end of the locking element moves into the clearance groove, allowing the pressure gauge connector to continue being inserted into the connector cavity. The force applied to the locking ring is then removed, and force is applied to the pressure gauge connector. The connector continues to be inserted until the locking ring groove on the pressure gauge connector is flush with the locking hole. At this point, under the action of the locking elastic element, the locking block moves rapidly to contact the locking wall, and the locking ring rotates until the clearance groove and locking hole are misaligned, i.e., the inner wall of the locking ring contacts the locking element. The locking element moves until one end is inserted into the locking ring groove on the pressure gauge connector, thus locking the pressure gauge connector.

[0014] This design eliminates the need for staff to determine whether the clearance groove is misaligned with the locking hole, improving the ease of pressure gauge testing. It also ensures that the locking ring keeps the clearance groove and locking hole misaligned, enhancing the stability of the connection between the pressure gauge connector and the disassembly fixture during testing.

[0015] Optionally, it also includes a rotating sleeve, wherein the sliding groove is formed on the outer wall of the watch connector connecting sleeve, the rotating sleeve is sleeved on the watch connector connecting sleeve, the locking block and the locking elastic element, and the rotating sleeve covers the opening of the sliding groove on the outer wall of the watch connector connecting sleeve.

[0016] By adopting the above technical solution, the sliding groove is set on the outer wall of the watch connector connecting sleeve, which facilitates the opening of the sliding groove during processing. By rotating the sleeve to cover the opening of the sliding groove on the outer wall of the watch connector, it is possible to effectively prevent the locking elastic element from falling out of the sliding groove during the extension and retraction process, effectively ensuring the stability of the extension and retraction of the locking elastic element, and at the same time playing a limiting and guiding role in the sliding of the locking block.

[0017] Optionally, the rotating sleeve is fitted onto the locking ring, the outer wall of the locking ring has a first mating surface, and the inner wall of the rotating sleeve has a second mating surface. When the rotating sleeve rotates, it can rotate until the first mating surface presses against the second mating surface, and the locking ring rotates together with the rotating sleeve.

[0018] By adopting the above technical solution, when the locking ring is rotated, the rotating sleeve is rotated directly. The first mating surface on the rotating sleeve rotates and presses against the second mating surface, thereby driving the locking ring to rotate. The locking ring is fitted onto the locking ring while simultaneously shielding the sliding groove. Compared to directly rotating the locking ring, the rotating sleeve increases the gripping area for the operator when rotating the locking ring, facilitating its rotation.

[0019] Optionally, the rotating sleeve is fitted with an anti-slip sleeve.

[0020] By adopting the above technical solution, compared with directly rotating the rotating sleeve, adding an anti-slip sleeve to the rotating sleeve and driving the rotating sleeve to rotate through the anti-slip sleeve can minimize the slippage when the worker rotates the rotating sleeve, which helps the worker to rotate the rotating sleeve.

[0021] Optionally, the rotating sleeve includes a limiting ring and a quick-clamp outer sleeve. The limiting ring covers the opening of the sliding groove on the outer wall of the watch connector connecting sleeve. The limiting ring includes multiple limiting petals, and the quick-clamp outer sleeve is rotatably sleeved on the limiting petals.

[0022] By adopting the above technical solution, the limiting ring and quick-clamp outer sleeve are combined to form the outer sleeve, and the limiting ring is disassembled into multiple limiting petals, greatly improving the ease of installation of the limiting ring. The quick-clamp outer sleeve restricts the separation between the limiting petals, thus ensuring the integrity of the limiting ring.

[0023] Optionally, the connector sleeve includes a sleeve body and a process ring sleeved on the sleeve body. The locking ring is sleeved on the sleeve body. The sleeve body has a slot and a retaining spring is provided in the slot. The two ends of the locking ring are respectively used to abut against the process ring and the retaining spring.

[0024] By adopting the above technical solution, when installing the locking ring, first the process ring is fitted onto the connecting sleeve body, then the locking ring is fitted onto the connecting sleeve body, and finally the snap ring is inserted into the slot. This completes the limiting of the locking ring along the axial direction of the connecting sleeve body. By utilizing a portion of the connecting sleeve of the dial connector for limiting, i.e., using the process ring for limiting, the limiting structure is effectively simplified, thereby simplifying the overall structure of the loading and unloading fixture of this application.

[0025] Optionally, the connector sleeve includes a sleeve body and a process ring sleeved on the sleeve body, and the sliding groove is formed on the process ring.

[0026] By adopting the above technical solution, the connecting sleeve of the gauge connector is combined with the main body of the connecting sleeve and the process ring, so that the sliding groove can be machined on the process ring before the process ring is installed on the gauge connector. This design improves the ease of machining the sliding groove on the connecting sleeve of the gauge connector.

[0027] Optionally, it also includes an adapter for connecting to a gas source and a sealing assembly for sealing, wherein the adapter has an installation cavity for communicating with the gas source, the adapter is connected to the gauge connector sleeve, and the installation cavity communicates with the connector cavity.

[0028] The sealing assembly includes an inner core disposed in the mounting cavity and a connector sealing ring disposed on the inner core. The connector sealing ring is used to abut against the pressure gauge connector. The inner core has a connecting hole that connects the connector cavity and the mounting cavity.

[0029] By adopting the above technical solution, when installing the mounting and dismounting fixture of this application, the adapter is connected to the air source. When connecting the pressure gauge, the pressure gauge connector is inserted into the connector cavity, and the end of the pressure gauge connector presses against the connector sealing ring. The connector sealing ring deforms and tightens against the pressure gauge connector. Gas from the air source enters the pressure gauge through the mounting cavity and the connecting hole, and the connector sealing ring effectively ensures the sealing performance.

[0030] Optionally, the inner core is slidably disposed in the mounting cavity along the direction from the mounting cavity to the connector cavity, and the sealing assembly further includes a sealing elastic element connected to the inner core. The sealing elastic element applies a force to the inner core along the direction from the mounting cavity to the connector cavity, and there is an inflation gap between the inner core and the cavity wall of the mounting cavity away from the connector cavity for gas to enter.

[0031] By adopting the above technical solution, when testing the pressure gauge, the gas output from the gas source enters the mounting cavity and fills the inflation gap, then enters the pressure gauge through the connecting hole. The gas in the inflation gap applies a force to the inner core along the direction from the mounting cavity to the connector cavity, causing the connector sealing ring to further press against the pressure gauge connector, thereby further improving the sealing performance between the pressure gauge connector sealing components. The sealing elastic element supports the inner core, ensuring the existence of the inflation gap, ensuring the connector sealing ring can contact the pressure gauge connector, and compressing the connector sealing ring when it contacts the pressure gauge connector, thereby increasing the compression amount of the connector sealing ring, increasing the contact area between the connector sealing ring and the pressure gauge connector, and thus improving the direct sealing performance between the inner core and the pressure gauge connector.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. Compared with connecting the pressure gauge connector and the loading and unloading fixture by bolt connection, this application uses a locking ring and locking element, and opens an annular locking groove on the pressure gauge connector to be tested, so that the total number of clockwise and counterclockwise rotations of the locking ring does not exceed 1 turn during one pressure gauge test, which effectively reduces the labor intensity of the staff and greatly improves the work efficiency.

[0034] 2. A locking block is added to the locking ring and force is applied to the locking block by the locking elastic element, so that when the locking ring groove on the pressure gauge connector is aligned with the locking hole, the locking ring can automatically rotate to the point where the clearance groove is misaligned with the locking hole, so that the end of the locking element is inserted into the locking ring groove on the pressure gauge connector. This setting further improves the convenience for workers to test the pressure gauge, and at the same time improves the stability of the connection between the pressure gauge connector and the disassembly fixture of this application during testing.

[0035] 3. The sliding inner core and the sealing elastic element allow the inflation gap to exist, so that the gas output from the air source can apply force to the inner core. The inner core applies the force to the joint sealing ring, thereby improving the fit between the joint sealing ring and the pressure gauge joint, and thus improving the sealing effect between the inner core and the pressure gauge joint.

[0041] The present application will be further described in detail below with reference to Figures 1-3.

[0042] This application discloses a quick-release clamp for a pressure gauge connector. Referring to Figures 1 and 2, the quick-release clamp for a pressure gauge connector includes an adapter 1 for connecting to a gas source, a sealing component 2 for sealing, a connector sleeve 3 for connecting to a pressure gauge connector, and a locking component 4 for locking the pressure gauge connector.

[0043] Referring to Figures 1 and 2, the adapter 1 is connected to the air source by a threaded connection. An installation cavity 11 is provided on the end face of the adapter 1, and an air inlet 12 is provided on the bottom wall of the installation cavity 11, which is connected to the air source through the air inlet 12.

[0044] Referring to Figures 2 and 3, the sealing assembly 2 is disposed in the mounting cavity 11. The sealing assembly 2 includes an inner core 21, a sealing elastic element 22, a sliding sealing ring 23, and a connector sealing ring 24. The inner core 21 is slidably disposed in the mounting cavity 11 along the direction from the air inlet 12 to the mounting cavity 11. A through hole 211 is formed on the inner core 21, extending through itself along the direction from the air inlet 12 to the mounting cavity 11. An outer sealing groove 212 is formed on the outer wall of the inner core 21, and the sliding sealing ring 23 is installed in the outer sealing groove 212 and abuts against the cavity wall of the mounting cavity 11. A top sealing groove 213 is formed on the end face of the inner core 21 away from the air inlet 12, and the connector sealing ring 24 is placed in the top sealing groove 213. The end of the connector sealing ring 24 extends out of the top sealing groove 213 and is used to abut against the pressure gauge connector.

[0045] Referring to Figures 2 and 3, the sealing elastic element 22 is a tower-shaped spring. The sealing elastic element 22 extends and retracts along the sliding direction of the inner core 21. Both ends of the sealing elastic element 22 abut against the inner core 21 and the cavity wall of the mounting cavity 11 near the air inlet 12, respectively. An inflation gap 13 exists between the inner core 21 and the cavity wall of the mounting cavity 11 near the air inlet 12, allowing gas to enter. In other embodiments, the sealing elastic element 22 can also be a cylindrical spring, or any other spring capable of applying a force to the inner core 21 along the direction from the air inlet 12 to the mounting cavity 11. The cross-sectional area of ​​the inner core 21 near the air inlet 12 is larger than the cross-sectional area of ​​the inner core 21 away from the air inlet 12, thus facilitating the application of a force from the gas entering the inflation gap 13 to the inner core 21 along the direction from the air inlet 12 to the mounting cavity 11.

[0046] Referring to Figures 2 and 3, the pressure gauge connector sleeve 3 includes a connector body 31 and a process ring 32. The connector body 31 is threaded onto the adapter 1. A connector cavity 311 for inserting the pressure gauge connector is provided on the end face of the connector body 31. The connector cavity 311 is located on the side of the mounting cavity 11 away from the air inlet 12 and communicates with the mounting cavity 11. One end of the inner core 21 with a top sealing groove 213 extends into the connector cavity 311.

[0047] Referring to Figures 2 and 3, the process ring 32 is sleeved on the connecting sleeve body 31, and the process ring 32 and the connecting sleeve body 31 are threaded together. In other embodiments, the process ring 32 and the connecting sleeve can also be directly connected by welding or other methods. Any method that can connect the separately produced process ring 32 to the connecting sleeve body 31 is acceptable.

[0048] Referring to Figures 2 and 3, the locking assembly 4 includes a locking ring 41 and six locking members 42. Six locking holes 312 communicating with the connector cavity 311 are provided on the outer wall of the connecting sleeve body 31. The locking holes 312 are circumferentially distributed around the axis of the connecting sleeve body 31. Each locking member 42 is slidably disposed in a different locking hole 312 along the radial direction of the connecting sleeve body 31. Each locking hole 312 includes a sliding hole 3121 and a limiting hole 3122. The sliding hole 3121 is located on the outer wall of the locking hole 312, and the limiting hole 3122 is located on the side of the sliding hole 3121 near the connector cavity 311 and communicates with the connector cavity 311. The locking member 42 is spherical. The diameter of the sliding hole 3121 is larger than the diameter of the locking member 42, and the diameter of the limiting hole 3122 is smaller than the diameter of the locking member 42. The limiting hole 3122 restricts the locking member 42 from falling into the connector cavity 311 through the locking hole 312.

[0049] Referring to Figures 2 and 3, the locking ring 41 is rotated and sleeved 5 on the connecting sleeve body 31. A groove 313 is provided on the outer wall of the connecting sleeve body 31, and a retaining spring 314 is installed in the groove 313. The two ends of the locking ring 41 are respectively used to abut against the process ring 32 and the retaining spring 314 to restrict the locking ring 41 from moving along the axial direction of the connecting sleeve body 31 until it separates from the connecting sleeve body 31.

[0050] Referring to Figures 2 and 3, the locking ring 41 covers the opening of the sliding hole 3121 on the outer wall of the connecting sleeve body 31. The diameter of the locking member 42 is larger than the depth of the locking hole 312. The two ends of the locking member 42 are respectively used to abut against the inner wall of the locking ring 41 and the pressure gauge connector. When one end of the locking member 42 is completely moved into the relief groove 411, the other end of the locking member 42 is completely located in the locking hole 312.

[0051] Referring to Figures 2 and 3, six clearance grooves 411 are provided on the inner wall of the locking ring 41. These grooves are evenly distributed circumferentially around the axis of the locking ring 41 and are spaced apart. Each groove 411 is used to allow the ends of different locking members 42 to extend into it. When one end of a locking member 42 is fully inserted into a clearance groove 411, the other end of the locking member 42 is completely located in the locking hole 312.

[0052] Referring to Figure 3, two locking blocks 412 are fixed on the locking ring 41, and the two locking blocks 412 are evenly distributed circumferentially around the axis of the locking ring 41. Two sliding grooves 321 are formed on the outer wall of the process ring 32, both extending around the axis of the process ring 32 and evenly distributed axially around the axis of the process ring 32. The two locking blocks 412 are slidably disposed in different sliding grooves 321. One of the groove walls of the locking groove is a locking wall 3211, which is used for the locking blocks 412 to abut against. When the locking blocks 412 abut against the locking wall 3211, each clearance groove 411 is offset from the locking hole 312.

[0053] Referring to Figure 3, each sliding groove 321 is provided with a locking elastic element 322, which is a spring. The locking elastic element 322 extends and retracts along the sliding direction of the locking block 412, and its two ends abut against the locking block 412 and the groove wall of the sliding groove 321, respectively. In other embodiments, the locking elastic element 322 may also be a spring sheet or the like, as long as it can apply a force to the locking block 412 in the direction of the locking wall 3211.

[0054] Referring to Figures 2 and 3, a rotating sleeve 5 is provided on the connecting sleeve 3 of the table connector. The rotating sleeve 5 includes a quick-clamp outer sleeve 51 and a limiting ring 52. The limiting ring 52 is mounted on the process ring 32 and covers the opening of the sliding groove 321 on the outer wall of the process ring 32. The two ends of the limiting ring 52 abut against the connecting sleeve body 31 and the locking ring 41, respectively, to restrict the axial movement of the limiting ring 52 along the process ring 32. The limiting ring 52 includes two symmetrically arranged limiting petals 521. The quick-clamp outer sleeve 51 is sleeved on the limiting petals 521 and the locking ring 41, and the quick-clamp outer sleeve 51 is connected to the two limiting petals 521 by bolts.

[0055] Referring to Figure 3, the outer wall of the locking ring 41 has twelve sequentially connected first mating surfaces 413. The first mating surfaces 413 are planar and circumferentially distributed around the axis of the locking ring 41, meaning the cross-section of the outer wall of the locking ring 41 is a regular dodecagon. The inner wall of the quick-clamp sleeve 51 has twelve sequentially connected second mating surfaces 511. The second mating surfaces 511 are planar and circumferentially distributed around the axis of the quick-clamp sleeve 51, meaning the inner wall cross-section of the portion of the quick-clamp sleeve 51 that is fitted onto the locking ring 41 is a regular dodecagon. When the quick-clamp sleeve 51 rotates, it rotates until the first mating surface 413 presses against the second mating surface 511, causing the locking ring 41 and the locking sleeve to rotate together. In other embodiments, the first mating surface 413 can also be a convex arc surface, and the second mating surface 511 can also be a concave arc surface. The first mating surface 413 and the second mating surface 511 do not necessarily extend around the axis of the locking ring 41; any method in which the rotation of the quick-clamp sleeve 51 can drive the locking ring 41 to rotate is acceptable.

[0056] Referring to Figures 2 and 3, the quick-clamp outer sleeve 51 is fitted with an anti-slip sleeve 53. The anti-slip sleeve 53 is an elastic rubber sleeve. By rotating the quick-clamp outer sleeve 51 through the anti-slip sleeve 53, the operator's hand can be prevented from slipping as much as possible.

[0057] The implementation principle of a quick-release clamp for a pressure gauge connector according to an embodiment of this application is as follows: Before testing the pressure gauge, a locking ring 41 groove for insertion of the locking element 42 needs to be opened on the outer wall of the connector of the pressure gauge to be tested. When testing the pressure gauge, the connector of the pressure gauge is directly inserted into the connector cavity 311, and the quick-clamp outer sleeve 51 is rotated by the anti-slip sleeve 53, which drives the locking ring 41 to rotate. The pressure gauge connector inserted into the connector cavity 311 presses against the end of the locking element 42. Since the locking element 42 is spherical, the pressure gauge connector applies a force to the locking element 42 in the opposite direction to the axial direction of the connecting sleeve body 31. The force is continued to be applied to the pressure gauge connector and the quick-clamp outer sleeve 51 is rotated by the anti-slip sleeve 53 until each clearance groove 411 is aligned with the different locking holes 312, the locking elastic element 322 is compressed, at which point the locking element 42 moves out of the connector cavity 311, and the pressure gauge connector can continue to be inserted into the connector cavity 311.

[0058] Then the force applied to the quick-clamp outer sleeve 51 can be removed, and the pressure gauge connector can be further inserted into the connector cavity 311 until the locking ring 41 groove on the pressure gauge connector is aligned with the locking hole 312. Under the action of the locking elastic element 322, the locking block 412 slides and drives the locking ring 41 to rotate, so that each clearance groove 411 is offset from the locking hole 312. The inner wall of the locking ring 41 abuts against the locking element 42 and pushes the locking element 42 to move, so that the end of the locking element 42 is inserted into the locking ring 41 groove on the pressure gauge connector. In this way, the connection between the pressure gauge connector and the loading and unloading fixture of this application can be realized. When separating the pressure gauge connector from the fixture of this application, an outward pulling force is applied to the pressure gauge, and the quick-clamp outer sleeve 51 is rotated until each clearance groove 411 is aligned with a different locking hole 312, and the pressure gauge connector can be pulled out of the pressure chamber.

[0059] This setup allows staff to monitor the pressure gauge as it rotates.

[0060] The pressure gauge connector inserted into the connector cavity 311 presses against the connector sealing ring 24. The connector sealing ring 24 deforms and fits against the pressure gauge connector to ensure the seal between the pressure gauge connector and the inner core 21. Gas output from the gas source enters the mounting cavity 11 through the air inlet 12, fills the inflation gap 13, and applies a force to the inner core 21 from the mounting cavity 11 to the connector cavity 311, so that the connector sealing ring 24 further presses against the pressure gauge connector.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
