Description

Technical Field

[0001] This invention relates to the field of environmental testing equipment technology, specifically a split-type high and low temperature test chamber. Background Technology

[0002] Split-type high and low temperature test chambers are core equipment in the field of environmental reliability testing. By separating the refrigeration system from the test chamber, they effectively solve the impact of equipment noise and heat dissipation on the laboratory environment. However, the refrigerant piping connecting the chamber to the outdoor unit has always been a technical bottleneck restricting its reliability, safety, and ease of use. Traditional installation mainly uses welding connections, which has inherent drawbacks such as long installation cycles, high dependence on professional personnel, difficulty in ensuring welding quality, and extreme inconvenience for subsequent maintenance and modification. To solve this problem, quick-connect coupling solutions have been introduced in existing technologies, but the following prominent issues still exist:

[0003] 1. Most existing quick couplings are simple top-opening valve structures. At the moment of connection and disconnection, the system seal is not entirely reliable, posing a risk of operation under pressure. In high-pressure refrigerant pipelines, misoperation could lead to a violent eruption of the medium, posing a serious safety threat to personnel and equipment.

[0004] 2. The widely used ball-locking joint has limited tensile strength and vibration resistance. In applications such as vibration testing of automotive parts, there is a risk of accidental loosening, and reliability cannot be guaranteed.

[0005] Therefore, it is necessary to provide a split-type high and low temperature test chamber to solve the problems mentioned in the background art. Summary of the Invention

[0011] Preferably, the torsion ring includes a torsion seat, a vertical plate, and an arc-shaped rod. The torsion seat is annular and has multiple vertical plates uniformly fixedly arranged on its inner side along the circumference. The multiple vertical plates are used to connect multiple connecting rods one or two. An arc-shaped rod is fixedly arranged on the vertical plate.

[0012] Both the male and female head assemblies are provided with annular grooves for the torsion ring to rotate and deflection grooves for the upright plate to rotate. An arc-shaped cavity is provided at the end of the deflection groove. An arc-shaped sleeve rod is fixedly installed in the arc-shaped cavity. The arc-shaped sleeve rod is slidably sleeved with the arc-shaped rod, and a spring connecting the upright plate and the wall of the arc-shaped cavity is sleeved on the outside of the arc-shaped sleeve rod.

[0013] Preferably, the push ring mechanism includes a push seat and a push rod.

[0021] Compared with the prior art, the present invention provides a split-type high and low temperature test chamber, which has the following beneficial effects:

[0022] In this invention, a purely mechanical structure design enforces a safe operating procedure. During connection, the male connector must be inserted into the female connector and fully tightened before the torsion ring can be released, opening the vane valve mechanism. Simultaneously, the locking mechanism locks the male and female connectors together. During disconnection, the torsion ring must be rotated to close the vane valve mechanism before the rotating plate can push the locking block out of the disconnection interface, unlocking the locking mechanism. This fundamentally eliminates the risk of plugging and unplugging under pressure. Furthermore, the insertion and locking action during connection triggers the unlocking torsion ring and opens the vane valve mechanism, eliminating the need for an additional valve opening step. Simply pushing the male connector into the female connector completes the connection, greatly improving installation efficiency. The push-block locking structure formed by the locking block and locking strip offers better tensile strength and vibration resistance, further ensuring the male and female connectors remain securely locked together under high pressure and alternating high and low temperature conditions.

Detailed Implementation

[0031] Please see Figures 1 to 7 In this embodiment of the invention, a split-type high and low temperature test chamber includes a chamber module connected by a connecting pipe. A quick-connect mechanism is provided at the connection point between the connecting pipe and the chamber module and the outdoor unit module. The quick-connect mechanism includes a male connector assembly 1, a female connector assembly 2, a blade valve mechanism 3, a locking mechanism 4, a torsion ring 5, and a push ring mechanism 6. The male connector assembly 1 can be inserted into the female connector assembly 2 and locked by the locking mechanism 4. Both the male connector assembly 1 and the female connector assembly 2 are equipped with blade valve mechanisms 3. The torsion ring 5 is rotatably disposed on the male connector assembly 1 and the female connector assembly 2 and is connected to the corresponding blade valve mechanism 3. The push ring mechanism 6 is slidably disposed in the torsion ring 5.

[0032] Additionally, please see Figure 2A stepped connecting groove can be provided at the end of the male connector assembly 1, and a deformable washer can be placed in this connecting groove. At the same time, a sliding washer is slidably provided to push the deformable washer. A stepped top groove adapted to this stepped connecting groove is provided in the female connector assembly 2. When the male connector assembly 1 and the female connector assembly 2 are slidably fitted together, the deformable washer will be squeezed and deformed, thus making it fit tightly against the outer side of the male connector assembly 1 and the inner side of the female connector assembly 2, thereby completely sealing the gap between the male connector assembly 1 and the female connector assembly 2, thus ensuring zero leakage under high pressure and high and low temperature alternating working conditions.

[0033] In this embodiment, the blade valve mechanism 3 includes a rotating base 31, an arc-shaped plate 32, an inner ring body 33, blades 34, and an outer ring body 35. Multiple arc-shaped plates 32 are uniformly fixedly arranged on the rotating base 31 along the circumference. The outer side of the arc-shaped plate 32 is fixedly connected to the male connector assembly 1 or the female connector assembly 2. The arc-shaped plate 32 is provided with a receiving groove 321 and a sealing groove 322. The inner ring body 33 is rotatably arranged on the rotating base 31. The outer ring body 35 is rotatably installed in the male connector assembly 1 or the female connector assembly 2. Multiple blades 34 are uniformly fixedly arranged between the inner ring body 33 and the outer ring body 35. The blades 34 can slide along the receiving groove 321 and can be sealed and locked into the sealing groove 322.

[0034] In particular, the two flow-facing ends of the arc-shaped plate 32 are provided with flow-guiding surfaces, which in turn generate less resistance to the fluid and avoid damage to the arc-shaped plate 32 and even the entire blade valve mechanism 3 under high pressure.

[0035] In this embodiment, the outer ring 35 of the male connector assembly 1 is fixedly connected to the torsion ring 5 via a connecting rod 1;

[0036] The outer ring 35 of the female head assembly 2 is fixedly connected to the torsion ring 5 via a connecting rod 2.

[0037] In other words, the torsion ring 5 and the vane valve mechanism 3 can be regarded as a whole. When the torsion ring 5 rotates, the vane 34 will also rotate. Thus, the opening and closing of the vane valve mechanism 3 can be controlled by controlling the rotation of the torsion ring 5.

[0038] In this embodiment, the locking mechanism 4 includes locking bars 41, rotating rods 42, and locking blocks 43. Multiple locking bars 41 are uniformly fixed along the circumferential direction on the outer side of the male connector 1. A break-in interface 411 is provided at one end of the locking bar 41 near the female connector 2. A rotating rod 42 is rotatably disposed within the locking bar 41. A rotating plate 421 is fixedly disposed on the rotating rod 42 and rotatably disposed along the break-in interface 411. Multiple sliding grooves 21 are provided along the circumferential direction on the inner side of the female connector 2. The locking bars 41 can slide along the sliding grooves 21. Two sliding cavities are symmetrically provided at the end of the sliding groove 21 away from the male connector 1. Locking blocks 43 are slidably disposed in the sliding cavities. The locking blocks 43 can slide into the break-in interface 411, and the rotating plate 421 can push the locking blocks 43 to slide.

[0039] In this embodiment, the torsion ring 5 includes a torsion seat 51, a vertical plate 52 and an arc-shaped rod 53. The torsion seat 51 is annular and a plurality of vertical plates 52 are uniformly fixedly arranged on its inner side along the circumference. The plurality of vertical plates 52 are used to connect a plurality of connecting rod one or connecting rod two. The arc-shaped rod 53 is fixedly arranged on the vertical plate 52.

[0040] Both the male head assembly 1 and the female head assembly 2 are provided with an annular groove 7 for the torsion ring 5 to rotate and a deflection groove 8 for the vertical plate 52 to rotate. An arc-shaped cavity 81 is provided at the end of the deflection groove 8. An arc-shaped sleeve rod 82 is fixedly installed in the arc-shaped cavity 81. The arc-shaped sleeve rod 82 is slidably sleeved with the arc-shaped rod 53, and a spring connecting the vertical plate 52 and the cavity wall of the arc-shaped cavity 81 is sleeved on the outside of the arc-shaped sleeve rod 82.

[0041] It should be noted that in the initial state, that is, when the male connector 1 and the female connector 2 are not engaged, the arc-shaped rod 53 is retracted in the arc-shaped sleeve 82, and the spring is in a compressed state.

[0042] In this embodiment, the push ring mechanism 6 includes a push seat 61 and a push rod 62. A plurality of push rods 62 are fixedly arranged circumferentially on one side of the push seat 61, and an annular sliding cavity for sliding of the push seat 61 is provided in the torsion seat 51. A plurality of locking grooves 511 penetrating the torsion seat 51 are provided circumferentially in the torsion seat 51, and the push rod 62 is slidably arranged along the locking grooves 511.

[0043] In this embodiment, multiple locking rods 9 are slidably disposed in the annular grooves 7 of both the male connector assembly 1 and the female connector assembly 2. A second spring is disposed between the locking rod 9 and the male connector assembly 1 and the female connector assembly 2. The locking rod 9 can slide into the locking groove 511, and the first push rod 62 can push the locking rod 9 to slide.

[0044] In this embodiment, a rotating ring 11 is rotatably disposed in the male connector assembly 1, and multiple arc-shaped racks 12 are embedded on the rotating ring 11. The rotating ring 11 is fixedly connected to the torsion ring 5.

[0045] A gear 422 is fixedly mounted on the rotating rod 42, and the gear 422 meshes with the arc-shaped rack 12.

[0046] In this embodiment, a plurality of guide rods 13 are slidably disposed in the male connector assembly 1. One end of the guide rod 13 is in slidable contact with the push base 61, and the other end penetrates the male connector assembly 1.

[0047] Multiple push rods 22 are fixedly arranged circumferentially on the female head assembly 2, and the push rods 22 can push the guide rod 13 to slide.

[0048] In this embodiment, a plurality of guide rods 23 are slidably disposed in the female head assembly 2. One end of the guide rod 23 is in slidable contact with the push base 61, and the other end penetrates the female head assembly 2 and extends into the slide groove 21.

[0049] The end of the locking bar 41 is fixedly provided with a top rod 412, which can push the guide rod 23 to slide.

[0050] In practice, the locking bar 41 of the male connector 1 is aligned with the slide groove 21 of the female connector 2 and slid in. Just before they come into contact, the second push rod 22 on the female connector 2 contacts the first guide rod 13, and simultaneously, the third push rod 412 at the end of the locking bar 41 contacts the second guide rod 23. Then, the male connector 1 is pushed further. As the sliding continues, the first guide rod 13 pushes the push seat 61 in the male connector 1 to slide, and the second guide rod 23 pushes the push seat 61 in the female connector 2 to slide. The sliding of the two push seats 61 further drives the first push rod 62 to slide, pushing the locking rod 9 out of the locking groove 511 in the torsion ring 5, thus freeing the rotation of the torsion ring 5. At the same time, the locking bar 41 pushes the locking block 43 at the end of the slide groove 21 to slide, simultaneously causing... When the locking block 43 and the break interface 411 are aligned, the two torsion rings 5 ​​are unrestricted and will automatically rotate under the action of the spring, which will drive the blade 34 to rotate. This causes the blade 34 to rotate out of the sealing groove 322 of the arc plate 32 and slide into the receiving groove 321, thus fully opening the blade valve mechanism 3. This achieves automatic valve opening during the connection process. At the same time as the torsion ring 5 rotates, the rotating ring 11 in the male connector assembly 1 will rotate synchronously, which will drive the gear 422 to rotate through the arc rack 12, i.e., the rotating rod 42 will rotate. This causes the rotating plate 421 to rotate from the state of horizontally pushing the two locking blocks 43 to the state of vertically disengaging from the push. At this time, the locking block 43 will slide into the break interface 411, thus completing the mechanical locking of the male connector assembly 1 and the female connector assembly 2.

[0051] When it is necessary to unlock the male connector assembly 1 and the female connector assembly 2, the operator can rotate the torsion ring 5 on the male connector assembly 1 and the female connector assembly 2 to return the torsion ring 5 to its initial position. During this process, the blade 34 will rotate accordingly, causing the blade valve mechanism 3 to close. At the same time, the rotation of the torsion ring 5 further drives the rotating ring 11 in the male connector assembly 1 to rotate, that is, the arc-shaped rack 12 will drive the gear 422 to rotate, causing the rotating plate 421 to rotate from the vertical position back to the horizontal position, that is, the two locking blocks 43 stuck in the break interface 411 are pushed out, thus completing the unlocking of the locking mechanism 4. And when the torsion ring 5 rotates... After the action, the locking rod 9 will coincide with the position of the locking groove 511, and then the male head assembly 1 will be pulled out from the female head assembly 2. During this process, the push rod 22 will no longer apply a pushing force to the guide rod 13, and the push rod 3 412 will no longer apply a pushing force to the guide rod 23. At this time, the locking rod 9 will slide back into the locking groove 511 under the action of the spring 2, that is, lock the torsion ring 5 and ensure that it will no longer rotate, further preventing the blade 34 from rotating. That is, after the male head assembly 1 and the female head assembly 2 are separated, the blade valve mechanism 3 set inside both will be closed to prevent liquid leakage.

[0052] Specifically, this invention, through a purely mechanical structure design, enforces a safe operating procedure. During connection, the male connector 1 must first be inserted into the female connector and fully tightened before the torsion ring 5 can be released, allowing the vane valve mechanism 3 to open. Simultaneously, the locking mechanism 4 locks the male connector 1 and female connector 2. During disconnection, the torsion ring 5 must first be rotated to close the vane valve mechanism 3 before the rotating plate 421 can rotate, pushing the locking block 43 out of the disconnect interface 411, thereby unlocking the locking mechanism 4. This fundamentally eliminates the risk of plugging and unplugging under pressure. During the connection process, the insertion and locking action triggers the unlocking torsion ring 5 and opens the blade valve mechanism 3, eliminating the need for additional valve opening steps. The male connector 1 can be pushed into the female connector 2 to complete the connection, greatly improving installation efficiency. Furthermore, the push-block locking structure formed by the locking block 43 and the locking strip 41 has better tensile strength and vibration resistance, further ensuring that the male connector 1 and the female connector 2 can be securely locked together under high pressure and high and low temperature alternating environments.

[0053] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
