Description

Technical Field

[0001] This invention relates to the field of fiber optic adapter technology, specifically to a fiber optic adapter with a double-opening automatic protective door. Background Technology

[0002] Fiber optic connectors are widely used in data centers, optical transmission equipment, and high-speed communication systems due to their multi-core, high-density connection features. The fiber optic adapters that come with them are mainly used to connect and position the two connectors to ensure stable transmission of optical signals.

[0003] Existing fiber optic adapters generally have open inlets, which can lead to frequent exposure of the connectors in applications requiring frequent plugging and unplugging, such as data center architecture maintenance. To prevent dust, impurities, and other foreign objects from entering the adapter, existing technologies include adapters with dustproof rotating doors equipped with elastic elements. When the fiber optic connector is inserted, the rotating door is opened, and the elastic element generates a restoring force. When the fiber optic connector is pulled out, the elastic element releases the restoring force, causing the rotating door to rotate back to its original position and close again. Furthermore, to reduce the large rotation radius required for the rotating door to open, the rotating door is usually designed as a double door.

[0004] However, the revolving doors in existing adapters with flexible dustproof revolving doors generally use torsion springs or cylindrical springs as the elastic components. Although torsion springs can save space and ensure a compact internal structure of the fiber optic adapter, the material cross-section of the torsion spring is subjected to bending stress during operation. Long-term reciprocating torsion can easily lead to metal fatigue, resulting in a high risk of breakage and a short service life. At the same time, when the fiber optic adapter itself is relatively small, the torsion spring installed at the rotating connection position of the door panel will also be smaller, making it difficult to guarantee the rebound force. Therefore, in order to extend the service life of the elastic components and ensure reliable door panel reset and closure, cylindrical springs are also used. However, when cylindrical springs are installed inside the adapter in a conventional way with the door panel, they occupy a lot of space, making the fiber optic adapter less compact. Summary of the Invention

[0005] The purpose of this invention is to provide a fiber optic adapter with a double-opening automatic protective door, so as to solve the technical problem that the elastic protective door of the adapter in the prior art cannot meet the requirements of both reducing space occupation and providing reliable elastic reset.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: A fiber optic adapter with a double-opening automatic protective door includes an adapter housing, a fiber optic splice sleeve, and a double-opening protective door mechanism. The fiber optic splice sleeve is disposed inside the port of the adapter housing. The double-opening protective door mechanism is disposed in cooperation with the port of the fiber optic splice sleeve facing the inside of the adapter housing. It also includes an elastic sliding guide mechanism for providing a rebound force for resetting the double-opening protective door mechanism. The elastic sliding guide mechanism includes a sliding guide and a spring. The sliding guide is slidably housed within the side wall of the fiber optic connector sleeve, and the spring is sleeved on the sliding guide. A movable corner mechanism is provided between the sliding guide and the double-opening protective door mechanism. During the rotational opening of the double-opening protective door mechanism, the sliding guide is driven to slide out of the fiber optic connector sleeve through the movable corner mechanism. During the process of the sliding guide sliding out of the fiber optic connector sleeve, the spring is compressed.

[0007] Preferably, the double-opening protective door mechanism includes two sets of rotating door panels, which are symmetrically distributed on both sides of the port of the fiber optic connector facing the inside of the adapter housing. Each set of rotating door panels is fixedly connected to an installation shaft, and the rotating door panels are rotatably connected to the corresponding edge of the port of the fiber optic connector via the installation shaft.

[0008] Preferably, both sides of the rotating door panel facing the outside of the adapter housing are fixedly connected with blocks.

[0009] Preferably, the elastic sliding guide mechanism is provided in four sets, and is distributed at each corner position of the optical fiber connector sleeve. The sliding guide component of each set of the elastic sliding guide mechanism includes a guide slide rod and a receiving slide groove. The receiving slide groove is opened at the corner position of the optical fiber connector sleeve. The guide slide rod slides through the receiving slide groove. The spring is sleeved on the guide slide rod. The guide slide rod is connected to the end of the corresponding mounting shaft through a movable corner mechanism. The end of the guide slide rod away from the rotating door panel is provided with a compression slider for compressing the spring.

[0010] Preferably, the movable corner mechanism includes a rotating top block and a mating hole. The rotating top block is fixedly connected to the end of the corresponding mounting shaft, and the mating hole is opened at the end of the guide slide rod near the rotating door panel. The rotating top block is mated within the mating hole.

[0011] Preferably, the adapter housing has snap-fit ​​holes on both sides of the side wall, and the fiber optic connector sleeve has snap-fit ​​blocks on both sides of the side surface that engage with the snap-fit ​​holes.

[0012] Preferably, the receiving slide is provided through the fiber optic connector sleeve, the end of the guide slide rod away from the rotating door panel extends to the outside of the adapter housing, the extrusion slider is a threaded connection sleeve, and the guide slide rod is provided with connecting threads that cooperate with the extrusion slider.

[0013] Preferably, the adapter includes a synchronization adjustment mechanism, and the extrusion slider corresponding to each group of elastic sliding guide mechanisms is connected to the synchronization adjustment mechanism, which enables all extrusion sliders to adjust their positions synchronously.

[0014] Preferably, the synchronous adjustment mechanism includes a connector, an elastic locking element, and a pressing crossbar. Each pressing slider is slidably sleeved on a corresponding guide rod, and a connector is fixedly connected to each pressing slider. Each pressing slider is connected to an elastic locking element through the connector. Multiple annular grooves are axially distributed on the outer wall of each guide rod, and the elastic locking element engages with the annular grooves. Two longitudinally aligned connectors are fixedly connected, and a pressing crossbar is provided between two laterally aligned connectors, with both ends of the pressing crossbar connected to corresponding elastic locking elements. The pressing crossbar is used to drive the elastic locking element to separate from the annular groove.

[0015] Preferably, the elastic locking element includes an elastic arched metal sheet and a locking block; one end of the elastic arched metal sheet is fixedly connected to a connector, and the other end is fixedly connected to a compression bar. The elastic arched metal sheets connected to the two connectors that are laterally aligned are symmetrically distributed. The locking block is fixedly connected to the side of the elastic arched metal sheet facing the guide slide rod and is used to lock into the annular locking groove.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. The present invention provides a resilient sliding guide mechanism for providing reset and rebound force for a double-opening protective door mechanism. This mechanism is slidably housed within the fiber optic connector sleeve, effectively saving space and avoiding impacting the compact design of the adapter. Simultaneously, the double-opening protective door mechanism uses a movable corner mechanism to drive the sliding guide component of the resilient sliding guide mechanism to compress the spring component, thereby converting rotational motion into linear motion. This facilitates the use of reliable cylindrical springs, allowing for the reliable use of these springs to provide effective elastic force, ensuring reliable reset of the double-opening protective door mechanism, and guaranteeing a longer service life.

[0017] 2. With the use of a rotating top block and a matching locking hole in the movable corner mechanism of the present invention, it is convenient to quickly assemble and connect the rotating door panel and the guide slide rod. At the same time, since the rotating top block is locked in the matching locking hole, the rotation of the guide slide rod can be effectively restricted. This makes it convenient to directly set the guide slide rod as a cylindrical rod body, which is convenient for assembly. It is also convenient to process structures such as threads or annular grooves.

[0018] 3. This invention, by setting a compression slider whose position can be adjusted along the guide slide, compensates for and repairs when the spring cannot provide the normal restoring force for the rotating door panel, making it easy to continue to use without replacing parts or scrapping the entire adapter, thus extending its service life.

[0019] 4. This invention provides an elastic locking element for positioning and fixing on each extrusion slider, and connects all the extrusion sliders into a whole, which facilitates the synchronous sliding adjustment of the whole. During adjustment, simply pinching the upper and lower extrusion bars will cause the elastic arched metal sheet of the corresponding elastic locking element on each extrusion slider to deform. The deformation of the elastic arched metal sheet will drive the locking block to disengage from the annular groove on the guide slide rod, thereby unlocking. Releasing it will automatically reset and lock into position. Attached Figure Description

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] Example 1 Because fiber optic adapters have open inlets, in applications requiring frequent plugging and unplugging of fiber optic connectors, such as data center architecture maintenance, the ports are easily exposed, allowing dust, impurities, and other foreign objects to enter the adapter, contaminating the internal connection area and affecting the stability of the fiber optic connection and signal transmission quality. To address this issue, existing technologies include dustproof fiber optic adapters. These adapters incorporate a rotating door connected by an elastic element. When the fiber optic connector is inserted, the rotating door opens, and the elastic element provides a restoring force. When the connector is removed, the elastic element releases the restoring force, causing the rotating door to rotate back to its original position and close again. To reduce the need for a large rotation radius during the opening and closing of the rotating door, which would require a longer adapter, the rotating door is typically designed as a double door. However, double-leaf door panels typically use torsion springs or cylindrical springs as the elastic components. While torsion springs can save space and ensure a compact internal structure for the fiber optic adapter, the material cross-section is subjected to bending stress during operation. Long-term reciprocating torsion can easily lead to metal fatigue and a high risk of breakage, resulting in a short service life. Furthermore, they provide relatively little elastic force, leading to poor door panel reset reliability. Additionally, given the relatively small size of the fiber optic adapter itself, the torsion spring installed at the rotating connection point of the door panel will also be smaller, making it difficult to guarantee the provided rebound force. Therefore, to extend the service life of the elastic components and ensure reliable door panel reset and closure, cylindrical springs are sometimes used. However, when cylindrical springs are installed inside the adapter in a conventional manner in conjunction with the door panel, they occupy a significant amount of space, resulting in a less compact fiber optic adapter.

[0024] To solve the above problems, such as Figures 1 to 11 This embodiment discloses a fiber optic adapter with a double-opening automatic protective door. The adapter includes an adapter housing 1, a fiber optic plug sleeve 2, and a double-opening protective door mechanism 3. The fiber optic plug sleeve 2 is disposed inside the port of the adapter housing 1 and is used for inserting the connector plug, serving as a guide and accommodating element. The double-opening protective door mechanism 3 is disposed in conjunction with the port of the fiber optic plug sleeve 2 facing the inside of the adapter housing 1. When the connector plug is inserted, the double-opening protective door mechanism 3 can be opened, and when the connector plug is pulled out, the double-opening protective door mechanism 3 can be reset and closed.

[0025] The adapter also includes an elastic sliding guide mechanism 4 for providing a rebound force for resetting the double-opening protective door mechanism 3. The elastic sliding guide mechanism 4 includes a sliding guide and a compressible spring 43. The sliding guide is slidably housed in the side wall of the fiber optic connector sleeve 2. The spring 43 can be set as a cylindrical spring and sleeved on the sliding guide. A movable corner mechanism is provided between the sliding guide and the double-opening protective door mechanism 3. During the rotation and opening process of the double-opening protective door mechanism 3, the movable corner mechanism drives the sliding guide to slide out of the fiber optic connector sleeve 2. During the process of the sliding guide sliding out of the fiber optic connector sleeve 2, the spring 43 is compressed. Thus, the spring 43 generates a rebound force, which facilitates the sliding guide to slide back and reset. Then, the double-opening protective door mechanism 3 is reset and closed by the movable snap-fit ​​mechanism. At this time, the entire elastic sliding guide mechanism 4 can be effectively housed back in the fiber optic connector sleeve 2.

[0026] Working principle: When the fiber optic connector plug is inserted into the adapter housing 1 and pushes the double-opening protective door mechanism 3 to open, the double-opening protective door mechanism 3 drives the sliding guide to slide out from the fiber optic plug sleeve 2 through the movable corner mechanism during the rotation opening process. During this process, the sliding guide compresses the spring 43, causing the spring 43 to compress and generate a rebound force. Thus, when the fiber optic connector plug is pulled out, the sliding guide can slide back to its original position by relying on the rebound force of the spring 43. In this way, the sliding guide can drive the double-opening protective door mechanism 3 to reset and close by relying on the movable corner mechanism.

[0027] It should be emphasized that the core improvement of this embodiment is that the elastic sliding guide mechanism 4, which provides the reset and rebound force for the double-opening protective door mechanism 3, is slidably housed inside the fiber optic plug sleeve 2, effectively saving space and avoiding affecting the compactness of the adapter. At the same time, the double-opening protective door mechanism 3 drives the sliding guide of the elastic sliding guide mechanism 4 to slide and compress the spring 43 through the movable corner mechanism, realizing the conversion of rotational motion into linear motion. This facilitates the use of cylindrical springs, making it easy to rely on them to provide effective elastic force, ensuring the reliable reset of the double-opening protective door mechanism 3, and ensuring a long service life.

[0028] like Figure 2In this embodiment, the double-opening protective door mechanism 3 includes a rotating door plate 31. Two sets of rotating door plates 31 are provided and symmetrically distributed on both sides of the port of the fiber optic plug sleeve 2 facing the inside of the adapter housing 1. When the two sets of rotating door plates 31 are spliced ​​together, they can effectively seal the port of the fiber optic plug sleeve 2, making it convenient for external impurities to enter the signal transmission area inside the adapter. Each set of rotating door plates 31 is fixedly connected to a mounting shaft 32, and the rotating door plate 31 is rotatably connected to the corresponding edge of the port of the fiber optic plug sleeve 2 through the mounting shaft 32. The mounting shaft 32 and the rotating door plate 31 can be integrally injection molded. When the mounting shaft 32 is installed, it can be provided with elastic retaining rings with openings on both sides of the corresponding edge of the port of the fiber optic plug sleeve 2, so that the end of the mounting shaft 32 is squeezed and locked into the elastic retaining ring to achieve docking. Of course, other methods can also be used to make the rotating door plate 31 and the fiber optic plug sleeve 2 rotatably connected together.

[0029] In some further embodiments, the rotating door plate 31 is fixedly connected to both sides of the end face facing the outside of the adapter housing 1 with a stop 33. The stop 33 can prevent the middle pin of the connector plug end face from directly contacting the rotating door plate 31 and causing damage.

[0030] like Figure 5 and Figure 6 In this embodiment, four sets of elastic sliding guide mechanisms 4 are provided, correspondingly distributed at each corner position of the fiber optic connector 2. Each set of elastic sliding guide mechanisms 4 includes a guide rod 41 and a receiving groove 42. The receiving groove 42 is located at the corner position of the fiber optic connector 2. The guide rod 41 slides through the receiving groove 42. A spring 43 is sleeved on the guide rod 41. One end of the guide rod 41 near the rotating door panel 31 protrudes from the receiving groove 42 and is connected to the end of the corresponding mounting shaft 32 via a movable corner mechanism. It should be noted that, since the end of the guide slide rod 41 is exposed, in order to prevent interference with the rotating door panel 31, a notch can be made at the corner of the rotating door panel 31 for avoidance; the end of the guide slide rod 41 away from the rotating door panel 31 is provided with a compression slider 44 for compressing the spring member 43. One end of the spring member 43 abuts against the inner wall of the receiving groove 42, and the other end abuts against the compression slider 44. That is, the diameter of the hole where the guide slide rod 41 passes through the receiving groove 42 is smaller than the diameter of the spring member 43, while the diameter of the inner cavity of the receiving groove 42 is larger than the diameter of the spring member 43.

[0031] In order to facilitate the assembly and connection of the guide slide rod 41 and the rotating door panel 31, such as Figure 8 and Figure 9The movable corner mechanism includes a rotating top block 46 and a mating hole 45. The rotating top block 46 is fixedly connected to the end of the corresponding mounting shaft 32. The mating hole 45 is opened at one end of the guide slide rod 41 near the rotating door panel 31. The rotating top block 46 is mated in the mating hole 45. One side of the rotating top block 46 contacts the inner wall of the mating hole 45, and the other side maintains a gap with the inner wall of the mating hole 45. The contact side is an arc surface.

[0032] It should be noted that when four sets of elastic sliding guide mechanisms 4 are set, each set of elastic sliding guide mechanisms 4 corresponds to one set of elastic sliding guide mechanisms 4 at both ends of the mounting shaft 32 of each rotating door panel 31.

[0033] When the connector plug is inserted into the rotating door panel 31, the rotating door panel 31 rotates due to the mounting shaft 32. During the rotation of the mounting shaft 32, the rotating top block 46 deflects, pushing against the side wall of the mating hole 45 in the opening direction. This pushes the guide slide rod 41 out of the receiving groove 42. During this process, the guide slide rod 41 drives the pressing slider 44 to move synchronously, which in turn compresses the spring 43, generating a rebound force. Thus, when the connector plug is pulled out, the mating hole 45 can push the rotating top block 46 in the opposite direction, causing it to deflect back to its original position, thereby allowing the rotating door panel 31 to rotate back to its original position. It should be noted that the spring 43 is initially compressed during installation to maintain a certain elasticity, thus facilitating the effective closing of the rotating door panel 31.

[0034] Furthermore, since the adapter housing 1 is generally a single piece with limited internal space, a fiber optic connector 2 is used as a transition point to facilitate the installation of internal components. This connector is designed to be detachable. In some specific implementations, it is specifically configured as follows: Figure 2 As shown, both sides of the adapter housing 1 are provided with snap-fit ​​holes 11, and both sides of the fiber optic plug sleeve 2 are provided with snap-fit ​​blocks 23 that engage with the snap-fit ​​holes 11. The fiber optic plug sleeve 2 can be made entirely of elastic plastic parts, or elastic plastic parts can be provided at the position of the snap-fit ​​blocks 23 for transition, or the snap-fit ​​blocks 23 can be made of elastic plastic parts. During the initial pressing and insertion of the fiber optic plug sleeve 2 into the adapter housing 1, the snap-fit ​​blocks 23 can elastically avoid the insertion. When the snap-fit ​​blocks 23 are aligned with the snap-fit ​​holes 11, the snap-fit ​​blocks 23 spring back and snap into the snap-fit ​​holes 11 to achieve snap-fit.

[0035] In this way, the rotating door plate 31 and the elastic sliding guide mechanism 4 can be assembled before the fiber optic plug sleeve 2 is installed inside the adapter housing 1, and then installed together into the adapter housing 1. The movable corner mechanism uses a rotating top block 46 to cooperate with the matching card hole 45, and can be directly plugged together. The rotating top block 46, the rotating door plate 31 and the mounting shaft 32 are integrally injection molded, making production and installation convenient.

[0036] In some further specific embodiments of this example, the fiber optic connector 2 is provided with elastic extension clamping arms 21 on both sides of the port facing the outside of the adapter housing 1, and the end of the elastic extension clamping arm 21 is provided with an arc transition inclined guide surface. The arc transition inclined guide surface is divided into two parts, one part facing the inside of the fiber optic connector 2 and the other part facing the outside of the fiber optic connector 2. The fiber optic connector plug is squeezed into the inside of the fiber optic connector 2 by being guided by the arc transition inclined guide surface on the outside side. During the squeezing insertion process, the elastic extension clamping arm 21 will open and generate a rebound force. When the fiber optic connector plug is fully inserted, the elastic extension clamping arm 21 will reset and hold the fiber optic connector plug to prevent it from easily falling off. During the process of pulling out the fiber optic connector plug, it can be pulled out from the fiber optic connector 2 by being guided by the arc transition inclined guide surface on the inside side.

[0037] Example 2 It is understandable that in Embodiment 1, although the spring member 43 can be a cylindrical spring and sleeved on the guide slide rod 41 to provide reliable rebound force, as the number of uses increases, after the spring member 43 is repeatedly compressed a certain number of times, elastic fatigue will occur, the effective length will be shortened, and thus it will be unable to provide effective rebound force, making it impossible for the rotating door panel 31 to effectively reset and close.

[0038] To solve the above problems, the receiving groove 42 is set through the fiber optic plug sleeve 2, that is, there is an opening of the receiving groove 42 on the end face of the fiber optic plug sleeve 2 facing the outside of the adapter housing 1. The end of the guide rod 41 away from the rotating door plate 31 extends to the outside of the adapter housing 1. The pressing slider 44 is a threaded connection sleeve, and the guide rod 41 is distributed with connecting threads that cooperate with the pressing slider 44. The pressing slider 44 has a certain length along the axial direction of the guide rod 41.

[0039] Working principle: When the spring 43 is continuously compressed, causing elastic fatigue and shortening of its original length, it can no longer effectively ensure the reset and closure of the rotating door panel 31. The exposed end of the guide slide rod 41 can be manually pulled to drive the rotating door panel 31 to the closed position through the movable corner mechanism. Then, the pressing slider 44, which acts as a threaded connecting sleeve, is screwed to displace the pressing slider 44 relative to the guide slide rod 41, which can then press against the spring 43 again, thus ensuring the reliable reset of the rotating door panel 31.

[0040] It should be emphasized that the core improvement of this embodiment is that by setting a compression slider 44 whose position can be adjusted along the guide slide bar 41, the spring component 43 can be compensated and repaired when it cannot provide the normal return force for the rotating door panel 31, so that it can continue to be used without replacing parts or scrapping the entire adapter, thus extending its service life.

[0041] It should be noted that, based on Embodiment 1, when the movable corner mechanism uses a rotating top block 46 and a mating hole 45, the rotating top block 46 is locked in the mating hole 45, which can effectively restrict the rotation of the guide slide rod 41. This makes it convenient for the guide slide rod 41 to be directly set as a cylindrical rod, which is convenient for assembly and also convenient for machining threads.

[0042] Example 3 It is understandable that in Embodiment 2, although the extrusion slider 44 can be set as a threaded connection sleeve with an adjustable position relative to the guide slide rod 41, since there are two sets of rotating door plates 31, and multiple sets of elastic sliding guide mechanisms 4 are set accordingly, each set of elastic sliding guide mechanism 4 corresponds to one extrusion slider 44, and the threaded connection is used, each extrusion slider 44 needs to be rotated and adjusted, which is not convenient to operate.

[0043] like Figure 7 To solve the above problems, another method is adopted to set the extrusion slider 44. Specifically, the adapter includes a synchronous adjustment mechanism 5. The extrusion slider 44 corresponding to each set of elastic sliding guide mechanisms 4 is connected to the synchronous adjustment mechanism 5. The synchronous adjustment mechanism 5 enables all extrusion sliders 44 to adjust their positions synchronously.

[0044] The synchronous adjustment mechanism 5 includes a connector 52, an elastic clip, and a pressing crossbar 51. Each pressing slider 44 is slidably sleeved on a corresponding guide rod 41, and a connector 52 is fixedly connected to each pressing slider 44. The connector 52 can be semi-annular and surrounds one side of the corresponding guide rod 41. Each pressing slider 44 is connected to an elastic clip through the connector 52. Multiple annular grooves 53 are axially distributed on the outer wall of each guide rod 41, and the annular grooves 53 are arranged relatively densely. The elastic clip engages with the annular grooves 53. Two longitudinally aligned connectors 52 are fixedly connected by a bracket, and a pressing crossbar 51 is provided between two laterally aligned connectors 52. The two ends of the pressing crossbar 51 are respectively connected to the corresponding elastic clips. The pressing crossbar 51 is used to drive the elastic clips to separate from the annular grooves 53.

[0045] In further specific implementation plans, such as Figure 10 and Figure 11As shown, the elastic clip includes an elastic arched metal sheet 54 and a clip 55. One end of the elastic arched metal sheet 54 is fixedly connected to the connector 52, and the other end is fixedly connected to the compression bar 51. The elastic arched metal sheets 54 connected to the two horizontally aligned connectors 52 are symmetrically distributed, and the concave surface of the elastic arched metal sheet 54 faces the guide slide bar 41. The clip 55 is fixedly connected to the side of the elastic arched metal sheet 54 facing the guide slide bar 41 and is centrally located. The clip 55 is used to engage with the annular groove 53. The elastic arched metal sheet 54 has a certain width in the axial direction of the guide slide bar 41, which can prevent bending along the axial direction of the guide slide bar 41.

[0046] Working principle: Each extrusion slider 44 is engaged in the corresponding position of the guide slide rod 41 by the locking block 55 on the corresponding elastic arched metal sheet 54, keeping the extrusion slider 44 in a fixed position relative to the guide slide rod 41, so as to extrude the spring member 43 with its movement. When all the pressing sliders 44 need to be adjusted synchronously, the pressing bars 51 on the upper and lower sides are pinched and pressed by hand. Both ends of each pressing bar 51 can press the corresponding elastic arched metal sheet 54, causing it to bend and arch further away from the corresponding guide rail 41. Thus, the locking block 55 set on the elastic arched metal sheet 54 can disengage from the annular locking groove 53 due to the arching action. Since the vertically aligned connecting parts 52 are fixedly connected together by the bracket, and the horizontally aligned connecting parts 52 are connected by the elastic arched metal sheet 54 and the pressing bar 51, all the pressing sliders 44 maintain a connection relationship. At this time, the operator can directly apply a pushing force along the axial direction of the guide rail 41 by pinching the pressing bar 51, so that all the pressing sliders 44 can slide and adjust their positions synchronously. When they touch the spring part 43 again, the pressing bar 51 can be released, so that the elastic arched metal sheet 54 can be reset and the corresponding locking block 55 can be driven to re-lock into the annular locking groove 53.

[0047] It should be noted that, due to the setting of the annular groove 53, the locking block 55 can be locked in as the elastic arched metal piece 54 moves non-linearly.

[0048] It should also be noted that, in order to facilitate external operation of the pressing bar 51, the pressing bar 51 naturally needs to be located outside the adapter port. In order to prevent the pressing bar 51 from limiting the travel of the guide slide bar 41, the end of each guide slide bar 41 away from the rotating door panel 31 can be extended to the outside of the adapter by a certain length, and the connector 52 and the elastic arched metal sheet 54 are both located at the position where the guide slide bar 41 extends out.

[0049] It should be emphasized that the core improvement of this embodiment is that each extrusion slider 44 is provided with an elastic clip for positioning and fixing, and each extrusion slider 44 is connected into a whole, which facilitates the overall synchronous sliding adjustment of the position. During adjustment, it is only necessary to pinch the upper and lower extrusion bars 51 to deform the elastic arched metal sheet 54 of the elastic clip provided for each extrusion slider 44. Thus, the deformation of the elastic arched metal sheet 54 drives the locking block 55 to disengage from the annular groove 53 on the guide slide rod 41, thereby unlocking. When released, it can automatically reset and lock into position.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
