Description

Technical Field

[0001] This application relates to the field of construction auxiliary facilities technology, and in particular to a prefabricated temporary passage device. Background Technology

[0002] During construction, building decoration, and temporary site setup, it is often necessary to erect temporary passageways between different floors and elevations to allow construction workers to move up and down and to transport small materials. At the same time, protective structures must be installed on both sides of the passageway to ensure the personal safety of construction workers during passage.

[0003] Existing prefabricated temporary access structures typically consist of multiple vertically arranged connecting columns, each integrally formed with several interlocking nodes at intervals along its length. During construction, the bottom of the connecting columns is supported on the ground or floor slab, and diagonal braces are installed between adjacent connecting columns. The two ends of the diagonal braces are inserted and fixed into the interlocking nodes on the corresponding connecting columns, thus forming a stable connection structure between adjacent connecting columns. The diagonal braces serve as guardrails on both sides of the access path to prevent construction workers from falling while passing through.

[0004] However, existing prefabricated temporary access devices have certain drawbacks. Because the disc-lock nodes and connecting columns are integrally molded, the disc-lock nodes cannot move axially relative to the connecting columns. Consequently, the relative positions of corresponding disc-lock nodes on adjacent connecting columns remain fixed, resulting in the inclination angle of the diagonal brace connecting the two disc-lock nodes being fixed. When this access device is applied to stair protection applications with varying inclination angles, the diagonal brace cannot adjust its inclination according to the actual inclination angle of the staircase, making it difficult to match the stair tread direction and thus failing to meet the safety protection requirements of diverse construction scenarios. How to solve these technical problems is a question that those skilled in the art need to consider. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a prefabricated temporary passage device, including a passage component, an adjustment component, and multiple sets of support components. All sets of support components are connected to the passage component; each support component includes a first support rod and a first protective rod. The first support rod includes a support portion and a connecting portion, with the connecting portion located on the outer peripheral surface of the support portion. The first protective rod is connected to the support portion via the connecting portion. The adjustment assembly includes multiple disc buckles with connecting holes. The disc buckles are fitted onto the outer periphery of the support portion and slidably connected to it. Each disc buckle includes a first rotating member, a second rotating member, and a locking member. The first and second rotating members are hinged together, and the locking member is movably connected to both. The first rotating member includes a first rotating structure and a first locking structure. One end of the first locking structure is hinged to the first rotating structure, and the other end is elastically connected to the first rotating structure. The second rotating member includes a second rotating structure and a second locking structure. One end of the second locking structure is hinged to the second rotating structure, and the other end is elastically connected to the second rotating structure. When the locking member is in contact with the first and second locking structures, the disc buckle is stationary relative to the support portion. When the locking member is separated from the first and second locking structures, the disc buckle can slide relative to the support portion.

[0006] Understandably, this application, by configuring the disc buckle to be fitted onto the outer circumferential surface of the support and forming a sliding connection with the support, allows the disc buckle to move freely axially on the support. The disc buckle is composed of a first rotating member, a second rotating member, and a locking member. After the first rotating member and the second rotating member are hinged, they can open or close around the hinge point, facilitating the disc buckle to be fitted onto the support from the side. In the first rotating member, one end of the first locking structure is hinged to the first rotating structure, and the other end is elastically connected to the first rotating structure. The second locking structure in the second rotating member also adopts the same arrangement of one end hinged and the other end elastically connected, so that the first locking structure and the second locking structure can fit against the support when under force. With the help of the movable connection between the locking member and the first and second rotating members, when the locking member simultaneously abuts against the first locking structure and the second locking structure, both the first locking structure and the second locking structure are pressed against the support, making the disc buckle stationary relative to the support. When the locking element separates from both the first and second locking structures simultaneously, the disc buckle can continue to slide relative to the support under the elastic restoring force of the elastic element. The prefabricated temporary passage device allows the disc buckle to slide against the support, locks the disc buckle when it moves to the appropriate position, and changes the tilt angle of the first guardrail by adjusting the height of the disc buckles on adjacent connecting parts, thereby adapting to the inclination of the staircase.

[0007] In one embodiment, the adjustment component includes two disc buckles. The first disc buckle is disposed above the connecting part, and the second disc buckle is disposed below the connecting part. The first disc buckle is connected to a plurality of plug rods on the side corresponding to the connecting part. The plurality of plug rods are arranged circumferentially at equal angles around the axis of the first disc buckle, and each plug rod is correspondingly disposed to a plug hole in the connecting part. The second disc buckle has a plurality of through holes, and each through hole is correspondingly disposed to a plug hole.

[0008] Understandably, the first disc buckle has multiple connecting rods on the side facing the connecting part, and these rods are arranged circumferentially at equal angles around the axis of the first disc buckle. This ensures that the connecting force provided by the connecting rods is evenly distributed along the circumference of the disc buckle, reducing the probability of force misalignment. Each connecting rod corresponds to a socket in the connecting part. The second disc buckle has through holes that correspond one-to-one with the sockets, allowing the connecting rods to pass through the sockets in the connecting part and into the through holes in the second disc buckle, thus connecting the first disc buckle, the connecting part, and the second disc buckle. This facilitates overall positioning after adjusting the height of the adjustment assembly.

[0009] In one embodiment, the first disc buckle has multiple connecting holes that penetrate the first disc buckle. The multiple connecting holes are arranged at equal circumferential intervals around the axis of the first disc buckle, and each connecting hole is alternately arranged with each insertion rod. The connecting part has multiple insertion holes that are arranged at equal circumferential intervals around the axis of the connecting part. The insertion holes penetrate the connecting part, and the through holes penetrate the second disc buckle.

[0010] Understandably, multiple connecting holes allow external components such as the first protective rod to be connected at different positions circumferentially via the disc buckle, facilitating the first disc buckle's support of multi-directional components. Each connecting hole and each insert rod are arranged alternately circumferentially, structurally offsetting the insert rod (which performs assembly positioning) and the connecting hole (which performs external connection), preventing interference between them at the same circumferential position. Multiple insert holes on the connecting part are arranged at equal circumferential intervals around the axis of the connecting part, with the insert holes penetrating the connecting part and the through holes penetrating the second disc buckle. This allows the insert rod to penetrate the connecting part and enter the second disc buckle in one go, facilitating continuous assembly in a single direction and simplifying on-site operation.

[0011] In one embodiment, the connecting portion has multiple receiving holes, all of which penetrate the connecting portion. The multiple receiving holes are arranged at equal circumferential intervals around the axis of the connecting portion. The distance between the center of each receiving hole and the axis of the connecting portion is equal to the distance between the center of each insertion hole and the axis of the connecting portion. Each receiving hole communicates with one insertion hole. The second disc buckle has multiple receiving holes and multiple insertion holes, all of which penetrate the second disc buckle. The multiple receiving holes are arranged at equal circumferential intervals around the axis of the second disc buckle. The distance between the center of each receiving hole and the axis of the second disc buckle is equal to the distance between the center of each insertion hole and the axis of the connecting portion. Each receiving hole communicates with a through hole. The diameter of the plug rod is smaller than the inner diameter of the insertion hole and the through hole. The plug rod has multiple snap-fit ​​grooves spaced at equal intervals along the axial direction. The snap-fit ​​grooves are opened on the outer circumferential surface of the plug rod. The diameter of the plug rod at the corresponding position of the snap-fit ​​groove is equal to the inner diameter of the receiving hole.

[0012] Understandably, the centers of the receiving hole and the insertion hole are located on the same circumference, facilitating lateral communication between them in the circumferential direction. Each receiving hole communicates with one insertion hole, and the receiving hole on the second disc buckle also communicates with the through hole. After the insertion rod extends into the insertion hole, it can shift circumferentially into the adjacent receiving hole, providing a path for switching height settings. The diameter of the insertion rod is smaller than the inner diameter of the insertion hole and the through hole, allowing the insertion rod to smoothly pass into the insertion hole and the through hole without being blocked. Multiple locking slots are equidistantly spaced along the axial direction on the insertion rod, and the diameter of the insertion rod at the corresponding position of the locking slot is equal to the inner diameter of the receiving hole, so that any one of the locking slots can form a circumferential engagement with the receiving hole. By relying on the cooperation of different locking slots and receiving holes, the axial position of the relative connection parts of the disc buckle can be adjusted.

[0013] In one embodiment, the adjustment assembly further includes two anti-detachment rings, one anti-detachment ring being disposed between the first disc buckle and the connecting portion, and the other anti-detachment ring being disposed between the connecting portion and the second disc buckle; the anti-detachment ring includes a first anti-detachment piece and a second anti-detachment piece, the first anti-detachment piece and the second anti-detachment piece being hinged together, the anti-detachment ring having multiple sliding holes penetrating through the anti-detachment ring, each sliding hole corresponding to a plug-in rod; the anti-detachment ring is connected to multiple anti-detachment structures, each anti-detachment structure corresponding to a plug hole, the anti-detachment structure being used to prevent the portion of the plug-in rod corresponding to the snap-fit ​​groove from sliding out of the receiving hole.

[0014] Understandably, the anti-detachment ring adds an extra limiting layer to the axial gap between the disc buckle and the connecting part. The anti-detachment ring includes a first anti-detachment piece and a second anti-detachment piece that are hinged to each other, allowing the anti-detachment ring to open and close through the hinge. During assembly, it can be laterally enclosed from the support part without needing to be slipped on from the end of the support part, facilitating on-site installation. Multiple through-holes on the anti-detachment ring are respectively set with corresponding insertion rods, ensuring that the insertion rod can still complete axial insertion and circumferential offset without being obstructed by the anti-detachment ring. Multiple anti-detachment structures connected to the anti-detachment ring correspond to a single insertion hole, and the anti-detachment structures are used to prevent the portion of the insertion rod corresponding to the locking groove from detaching from the receiving hole, reducing the probability of the insertion rod coming out of the receiving hole under construction vibration or accidental force.

[0015] In one embodiment, the first rotating member is connected to a plug-in structure, which is located on the side of the first rotating member away from the hinge end; the second rotating member is connected to a snap-fit ​​structure, which is located on the side of the second rotating member away from the hinge end; both the plug-in structure and the snap-fit ​​structure are provided with adjustment holes, and the locking member is connected to the plug-in structure and the snap-fit ​​structure through the adjustment holes.

[0016] Understandably, the plug-in and snap-fit ​​structures work together so that after the two rotating parts surround the support, they can be joined and closed at the opposite end to the hinge end, forming a ring constraint around the support. Both the plug-in and snap-fit ​​structures have adjustment holes, and the locking element connects to both through the adjustment holes, allowing the locking element to simultaneously constrain the open ends of the two rotating parts, facilitating the locking or releasing of the disc buckle with a single action.

[0017] In one embodiment, both the first rotating structure and the first locking structure are configured to fit the shape of the support portion; both the second rotating structure and the second locking structure are configured to fit the shape of the support portion.

[0018] Understandably, when the disc buckle is closed, the inner contours of the first rotating structure, the first locking structure, the second rotating structure, and the second locking structure can fit and be distributed along the outer circumferential surface of the support, which helps to equalize the clamping pressure of the disc buckle on the support and maintain a good coaxial relationship between the disc buckle and the support, making it easier for the disc buckle to slide along the axial direction of the support when it is released.

[0019] In one embodiment, the first rotating member includes a plurality of elastic members, all of which are located between the first rotating structure and the first locking structure, and each elastic member is connected to the first rotating structure and the first locking structure respectively; the second rotating member includes a plurality of elastic members, all of which are located between the second rotating structure and the second locking structure, and each elastic member is connected to the second rotating structure and the second locking structure respectively.

[0020] Understandably, the elastic connection between the first locking structure and the first rotating structure is shared by multiple points, distributing the elastic force along the extension direction of the locking structure. The elastic element is located between the first rotating structure and the first locking structure, stretching and storing elastic restoring force when the locking element applies pressure. When the locking element separates from the first and second locking structures, the elastic element releases its preload, causing the locking structure to retract, facilitating the shift of the disc buckle into a sliding state and promoting stable switching between the locking and releasing states.

[0021] In one embodiment, the disc buckle further includes a snap-fit ​​plate, which is annular in shape. A connecting cavity is provided on the outer side of the disc buckle, and the connecting cavity is distributed along the outer peripheral surface of the disc buckle. A connecting structure is connected to the inner sidewall of the snap-fit ​​plate, and the snap-fit ​​plate has multiple snap-fit ​​holes, which are arranged at equal circumferential intervals around the axis of the snap-fit ​​plate.

[0022] Understandably, the addition of a ring-shaped locking plate to the disc buckle, with its inner diameter slightly larger than the outer diameter of the disc buckle, allows the locking plate to be coaxially fitted onto the outside of the disc buckle, facilitating a coaxial connection. Connecting cavities distributed along the outer circumference of the disc buckle are formed on its outer side, and these cavities are fitted with a connecting structure on the inner wall of the locking plate. This allows the locking plate and the disc buckle to engage through the interlocking of the connecting cavities and the connecting structure, preventing the locking plate from rotating relative to the disc buckle or coming off. Multiple locking holes on the locking plate are arranged circumferentially at equal angles around its axis, expanding the disc buckle's connection capabilities.

[0023] In one embodiment, the outer side of the card holder extends horizontally beyond the outer side of the passage component projected in the horizontal direction. The support assembly also includes a plurality of second support rods, each of which extends into the snap-fit ​​hole of the portion of the passage assembly projected in the horizontal direction and extends upward; the support assembly also includes a plurality of second protective rods, some of which are located at the top of the second support rods and are connected end to end in the horizontal direction; the remaining second protective rods are inclined in a direction parallel to the first protective rod.

[0024] Understandably, the outer side of the locking plate extends horizontally beyond the passage component, providing an access point for the second protective bar support to be placed outside the passage component. The support component includes multiple second support bars, each of which extends into the locking plate through a snap-fit ​​hole on the outer side of the passage component's horizontal projection and extends upwards. This allows the second support bar to be vertically positioned using the snap-fit ​​hole on its extended portion, forming another set of vertical fulcrums outside the passage component. Some of the second protective bars are located at the top of the second support bars and are connected end-to-end horizontally, forming a horizontally closed fence frame at the top of the second support bars, providing lateral protection at the top boundary. The remaining second protective bars are inclined in a direction parallel to the first protective bars, ensuring that the angle of the inclined second protective bars on the outer side matches the inclination angle of the stairs adapted to the first protective bars. This allows the inner first protective bars and the outer second protective bars to extend together along the staircase, improving the safety of the prefabricated temporary passage device.

[0035] The following combination Figures 1 to 9 This application will be described in further detail below.

[0036] In one embodiment, a prefabricated temporary passage device includes a passage component 1, an adjustment component 3, and multiple sets of support components 2. All sets of support components 2 are connected to the passage component 1. Each support component 2 includes a first support rod 21 and a first protective rod 22. The first support rod 21 includes a support portion 211 and a connecting portion 212. The connecting portion 212 is located on the outer peripheral surface of the support portion 211, and the first protective rod 22 is connected to the support portion 211 via the connecting portion 212. Adjustment component 3 includes multiple disc buckles 31 with connecting holes 316. The disc buckles 31 are sleeved on the outer peripheral surface of the support portion 211 and slidably connected to the support portion 211. Each disc buckle 31 includes a first rotating member 311, a second rotating member 312, and a locking member 313. The first rotating member 311 and the second rotating member 312 are hinged together, and the locking member 313 is movably connected to the first rotating member 311 and the second rotating member 312. The first rotating member 311 includes a first rotating structure 3111 and a first locking structure 3112. One end of the first locking structure 3112 is hinged to the first rotating structure 3111, and the other end of the first locking structure 3112... The first rotating structure 3111 is elastically connected to the second rotating structure 3111; the second rotating member 312 includes a second rotating structure 3121 and a second locking structure 3122, one end of the second locking structure 3122 is hinged to the second rotating structure 3121, and the other end of the second locking structure 3122 is elastically connected to the second rotating structure 3121; when the locking member 313 is in contact with the first locking structure 3112 and the second locking structure 3122, the disc buckle 31 is stationary relative to the support portion 211; when the locking member 313 is separated from the first locking structure 3112 and the second locking structure 3122, the disc buckle 31 can slide relative to the support portion 211.

[0037] In this embodiment, refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9The passage component 1 is plate-shaped and inclined. Multiple sets of support components 2 are located below the passage component 1 and connected to it. In each set of support components 2, the first support rod 21 is arranged vertically, with its top abutting against the passage component 1. The support portion 211 in the first support rod 21 is rod-shaped, and the connecting portion 212 protrudes circumferentially from the outer circumferential surface of the support portion 211 and is integrally formed with it. The connecting portion 212 is annular. A ring-shaped buckle 31 is fitted onto the outer circumferential surface of the support portion 211. The outer diameter of the buckle 31 is equal to the outer diameter of the connecting portion 212. The buckle 31 can slide along the axial direction of the support portion 211 and rotate around its axial direction. Both the first rotating member 311 and the second rotating member 312 are semi-annular. One end of the first rotating member 311 is hinged to one end of the second rotating member 312. After the buckle 31 opens at the hinge, it can be laterally fitted into the support portion 211. The locking member 313 can be a bolt, and it movably abuts against the first locking structure 3112 and the second locking structure 3122 on the side away from the hinge end via the first rotating member 311 and the second rotating member 312. The first protective rod 22 is rod-shaped. When there is no need to adjust the tilt angle of the first protective rod 22, both ends of the first protective rod 22 are connected to the support parts 211 of the two adjacent first support rods 21. When it is necessary to adjust the tilt angle of the first protective rod 22, both ends of the first protective rod 22 are connected to the disc buckles 31 on the outer peripheral surface of the two adjacent first support rods 21.

[0038] This application configures the disc buckle 31 to be fitted onto the outer peripheral surface of the support portion 211 and to form a sliding connection with the support portion 211, allowing the disc buckle 31 to move freely in the axial position on the support portion 211. The disc buckle 31 is composed of a first rotating member 311, a second rotating member 312, and a locking member 313. After the first rotating member 311 and the second rotating member 312 are hinged, they can open or close around the hinge point, facilitating the disc buckle 31 to be fitted onto the support portion 211 from the side. In the first rotating member 311, one end of the first locking structure 3112 is hinged to the first rotating structure 3111, and the other end is elastically connected to the first rotating structure 3111. The second locking structure 3122 in the second rotating member 312 also adopts the same arrangement of one end hinged and the other end elastically connected, so that the first locking structure 3112 and the second locking structure 3122 can fit against the support portion 211 when subjected to force. With the locking member 313 connected to the first rotating member 311 and the second rotating member 312, when the end of the locking member 313 simultaneously abuts against the ends of the first locking structure 3112 and the second locking structure 3122, both the first locking structure 3112 and the second locking structure 3122 are pressed against the support part 211, making the disc buckle 31 stationary relative to the support part 211. When the end of the locking member 313 separates from the ends of the first locking structure 3112 and the second locking structure 3122, under the elastic restoring force of the elastic member 3114, the disc buckle 31 can continue to slide relative to the support part 211. The prefabricated temporary passage device allows the disc buckle 31 to move along the connecting part 212, and locks the disc buckle 31 when it moves to the appropriate position. By changing the height of the disc buckle 31 on the adjacent connecting part 212, the tilt angle of the first protective rod 22 can be adjusted to adapt to the inclination of the staircase.

[0039] In one embodiment, the first rotating member 311 is connected to a plug-in structure 3113, which is located on the side of the first rotating member 311 away from the hinge end; the second rotating member 312 is connected to a snap-fit ​​structure 3123, which is located on the side of the second rotating member 312 away from the hinge end; both the plug-in structure 3113 and the snap-fit ​​structure 3123 are provided with adjustment holes 31131, and the locking member 313 is connected to the plug-in structure 3113 and the snap-fit ​​structure 3123 through the adjustment holes 31131.

[0040] In this embodiment, refer to Figure 7 and Figure 8Both the insertion structure 3113 and the snap-fit ​​structure 3123 are plate-shaped, and the snap-fit ​​structure 3123 has a slot at the corresponding position of the insertion structure 3113. When the first rotating member 311 and the second rotating member 312 engage with the support part 211, the insertion structure 3113 and the snap-fit ​​structure 3123 are close to each other on the side opposite to the hinge end. Both the insertion structure 3113 and the snap-fit ​​structure 3123 have through-holes 31131, and the two adjustment holes 31131 are coaxially aligned in the engaged state. The locking member 313 passes through the adjustment holes 31131 on the insertion structure 3113 and the snap-fit ​​structure 3123 in sequence, and simultaneously abuts against the insertion structure 3113 and the snap-fit ​​structure 3123.

[0041] The plug-in structure 3113 cooperates with the snap-fit ​​structure 3123 so that after the two rotating parts surround the support part 211, they can be closed at the opposite end to the hinge end, forming a ring constraint around the support part 211. Both the plug-in structure 3113 and the snap-fit ​​structure 3123 are provided with adjustment holes 31131, and the locking member 313 is connected to both of them through the adjustment holes 31131, so that the locking member 313 can simultaneously constrain the open ends of the two rotating parts, making it easy to lock or release the disc buckle 31 with a single action.

[0042] In one embodiment, the first rotating structure 3111 and the first locking structure 3112 are both configured to fit the shape of the support portion 211; the second rotating structure 3121 and the second locking structure 3122 are both configured to fit the shape of the support portion 211.

[0043] In this embodiment, refer to Figure 7 , Figure 8 and Figure 9 The first rotating structure 3111 is an arc-shaped plate, and the first locking structure 3112 is also an arc-shaped plate located inside the first rotating structure 3111. One end of the first locking structure 3112 is hinged to the first rotating structure 3111 via a pin, and the other end of the first locking structure 3112 is elastically connected to the first rotating structure 3111. The positional relationship and connection method of the second rotating structure 3121 and the second locking structure 3122 in the second rotating member 312 are the same as those in the first rotating member 311. In the closed state, the first rotating member 311 and the second rotating member 312 together form a circular ring clamp structure that fits against the support part 211.

[0044] When the disc buckle 31 is closed, the inner contours of the first rotating structure 3111, the first locking structure 3112, the second rotating structure 3121, and the second locking structure 3122 can be distributed along the outer peripheral surface of the support portion 211. This helps to equalize the clamping pressure of the disc buckle 31 on the support portion 211 and maintain a good coaxial relationship between the disc buckle 31 and the support portion 211, making it easier for the disc buckle 31 to slide along the axial direction of the support portion 211 when it is released.

[0045] In one embodiment, the first rotating member 311 includes a plurality of elastic members 3114, all of which are located between the first rotating structure 3111 and the first locking structure 3112, and each elastic member 3114 is connected to the first rotating structure 3111 and the first locking structure 3112 respectively; the second rotating member 312 includes a plurality of elastic members 3114, all of which are located between the second rotating structure 3121 and the second locking structure 3122, and each elastic member 3114 is connected to the second rotating structure 3121 and the second locking structure 3122 respectively.

[0046] In this embodiment, refer to Figure 7 and Figure 8 In the first rotating member 311, multiple elastic elements 3114 are evenly sandwiched within the gap between the first rotating structure 3111 and the first locking structure 3112. One end of each elastic element 3114 is connected to the inner surface of the first rotating structure 3111, and the other end of each elastic element 3114 is connected to the outer surface of the first locking structure 3112. The multiple elastic elements 3114 are arranged at intervals along the extending direction of the first locking structure 3112. The arrangement and connection method of the elastic elements 3114 in the second rotating member 312 are the same as those in the first rotating member 311. The elastic elements 3114 can be springs. In their natural state, the elastic elements 3114 pull the first locking structure 3112 closer to the first rotating structure 3111, and simultaneously pull the second locking structure 3122 closer to the second rotating structure 3121.

[0047] The elastic connection between the first locking structure 3112 and the first rotating structure 3111 is shared by multiple points, distributing the elastic force along the extension direction of the locking structure. The elastic element 3114 is located between the first rotating structure 3111 and the first locking structure 3112, so that when the locking element 313 applies pressure, the elastic element 3114 is stretched and stores elastic restoring force. When the locking element 313 separates from the first locking structure 3112 and the second locking structure 3122, the elastic element 3114 releases the elastic restoring force, causing the first locking structure 3112 to move towards the first rotating structure 3111 and the second locking structure 3122 to move towards the second rotating structure 3121. This facilitates the sliding state of the disc buckle 31 and promotes stable switching between the locking and releasing states.

[0048] In one embodiment, the adjustment component 3 includes two disc buckles 31. The first disc buckle 31 is disposed above the connecting part 212, and the second disc buckle 31 is disposed below the connecting part 212. The first disc buckle 31 is connected to a plurality of plug rods 314 on the side corresponding to the connecting part 212. The plurality of plug rods 314 are arranged circumferentially at equal angles around the axis of the first disc buckle 31, and each plug rod 314 is correspondingly disposed to a plug hole 2121 of the connecting part 212. The second disc buckle 31 has a plurality of through holes 315, and each through hole 315 is correspondingly disposed to a plug hole 2121.

[0049] In this embodiment, refer to Figures 5 to 8 The two disc buckles 31 in the adjusting assembly 3 are distributed vertically along the axial direction of the support portion 211. The first disc buckle 31 is located above the connecting portion 212 and corresponds to the upper end face of the connecting portion 212 at a distance. The second disc buckle 31 is located below the connecting portion 212 and corresponds to the lower end face of the connecting portion 212 at a distance. One end of each of the multiple plug-in rods 314 is connected to the lower end face of the first disc buckle 31 facing the connecting portion 212. The insertion hole 2121 of the connecting portion 212 passes through the connecting portion 212 along the axial direction of the support portion 211. Each plug-in rod 314 corresponds axially to one insertion hole 2121 on the connecting portion 212. The through hole 315 and the insertion hole 2121 are the same size and are both circular holes. The multiple through holes 315 on the second disc buckle 31 correspond one-to-one with the multiple insertion holes 2121. After passing through the insertion hole 2121, the plug-in rod 314 can continue to extend into the corresponding through hole 315.

[0050] The first disc buckle 31 has multiple insertion rods 314 connected to the side facing the connecting part 212. These insertion rods 314 are arranged at equal circumferential intervals around the axis of the first disc buckle 31, ensuring that the connecting force provided by the insertion rods 314 is evenly distributed along the circumference of the disc buckle 31, thus reducing the probability of force misalignment of the disc buckle 31. Each insertion rod 314 corresponds to an insertion hole 2121 in the connecting part 212. The second disc buckle 31 has through holes 315 that correspond one-to-one with the insertion holes 2121, allowing the insertion rods 314 to pass sequentially through the insertion holes 2121 on the connecting part 212 and extend into the through holes 315 of the second disc buckle 31. This connects the first disc buckle 31, the connecting part 212, and the second disc buckle 31, facilitating overall positioning after adjusting the height of the adjusting assembly 3.

[0051] In one embodiment, the first disc buckle 31 has a plurality of connecting holes 316, which penetrate the first disc buckle 31. The plurality of connecting holes 316 are arranged at equal circumferential intervals around the axis of the first disc buckle 31, and each connecting hole 316 is alternately arranged with each insertion rod 314. The connecting part 212 has a plurality of insertion holes 2121, which are arranged at equal circumferential intervals around the axis of the connecting part 212. The insertion holes 2121 penetrate the connecting part 212, and the through holes 315 penetrate the second disc buckle 31.

[0052] In this embodiment, refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Multiple connecting holes 316 and multiple insertion rods 314 are arranged adjacent to each other and alternately in the circumferential direction. Multiple insertion holes 2121 on the connecting part 212 penetrate the connecting part 212 along the axial direction of the connecting part 212, and the multiple insertion holes 2121 are arranged at equal angular intervals around the axis of the connecting part 212. A through hole 315 on the second disc buckle 31 penetrates the second disc buckle 31 along the thickness direction. The through hole 315 and the insertion hole 2121 are opened correspondingly in the axial direction. The insertion rod 314 can be inserted into the insertion hole 2121 and then inserted into the through hole 315 in sequence.

[0053] Multiple connecting holes 316 allow external components such as the first protective rod 22 to be connected at different positions around the circumference of the disc buckle 31, facilitating the first disc buckle 31's support of multi-directional components. Each connecting hole 316 and each insertion rod 314 are arranged alternately around the circumference, so that the insertion rod 314, which performs the assembly positioning function, and the connecting hole 316, which performs the external connection function, are structurally staggered to avoid interference between them at the same circumferential position. Multiple insertion holes 2121 on the connecting part 212 are arranged at equal angular intervals around the axis of the connecting part 212, and the insertion holes 2121 penetrate the connecting part 212, while the through holes 315 penetrate the second disc buckle 31, allowing the insertion rod 314 to penetrate the connecting part 212 and enter the second disc buckle 31 in one go. This facilitates continuous assembly in a single direction and is convenient for on-site operation.

[0054] In one embodiment, the connecting portion 212 has a plurality of receiving holes 2122, each of which penetrates the connecting portion 212. The plurality of receiving holes 2122 are arranged at equal circumferential intervals around the axis of the connecting portion 212. The distance between the center of each receiving hole 2122 and the axis of the connecting portion 212 is equal to the distance between the center of each insertion hole 2121 and the axis of the connecting portion 212. Each receiving hole 2122 communicates with one insertion hole 2121. The second disc buckle 31 has a plurality of receiving holes 2122 and a plurality of insertion holes 2121, each of which penetrates the second disc buckle 31. The plurality of receiving holes 2122 are arranged at equal circumferential intervals around the axis of the second disc buckle 31. The distance between the center of each receiving hole 2122 and the axis of the second disc buckle 31 is equal to the distance between the center of each insertion hole 2121 and the axis of the connecting portion 212. Each receiving hole 2122 communicates with one through hole 315. The diameter of the plug rod 314 is smaller than the inner diameter of the plug hole 2121 and the through hole 315. The plug rod 314 is provided with multiple snap-fit ​​grooves 3141 at equal intervals along the axial direction. The snap-fit ​​grooves 3141 are opened on the outer peripheral surface of the plug rod 314. The diameter of the plug rod 314 at the corresponding position of the snap-fit ​​groove 3141 is equal to the inner diameter of the receiving hole 2122.

[0055] In this embodiment, refer to Figures 5 to 9 Multiple receiving holes 2122 are provided in the connecting part 212 and extend through the connecting part 212 along the axial direction of the connecting part 212. The centers of the multiple receiving holes 2122 and the centers of the multiple insertion holes 2121 are located on the same circumferential trajectory and are distributed alternately. Each receiving hole 2122 is laterally connected to an adjacent insertion hole 2121, forming a composite hole position that combines axial insertion and circumferential offset. Each through hole 315 provided in the second disc buckle 31 is connected to an adjacent receiving hole 2122.

[0056] The centers of the receiving hole 2122 and the insertion hole 2121 are located on the same circumference, facilitating lateral communication between them. Each receiving hole 2122 communicates with one insertion hole 2121, and the receiving hole 2122 on the second disc buckle 31 is arranged in the same manner and communicates with the through hole 315. After extending into the insertion hole 2121, the insertion rod 314 can be circumferentially offset into the adjacent receiving hole 2122. The outer diameter of the insertion rod 314 is smaller than the inner diameter of the insertion hole 2121 and the through hole 315, allowing the insertion rod 314 to pass smoothly through the insertion hole 2121 and the through hole 315. The plug rod 314 has multiple locking slots 3141 spaced equidistantly along the axial direction, and the diameter of the plug rod 314 at the corresponding position of the locking slot 3141 is equal to the inner diameter of the receiving hole 2122, so that any one of the locking slots 3141 can form a circumferential engagement with the receiving hole 2122. By relying on the cooperation between the locking slots 3141 at different positions and the receiving hole 2122, the axial position of the disc buckle 31 relative to the connecting part 212 can be adjusted.

[0057] In one embodiment, the adjusting component 3 further includes two anti-detachment rings 32. One anti-detachment ring 32 is disposed between the first disc buckle 31 and the connecting portion 212, and the other anti-detachment ring 32 is disposed between the connecting portion 212 and the second disc buckle 31. The anti-detachment ring 32 includes a first anti-detachment piece 321 and a second anti-detachment piece 322, which are hinged together. The anti-detachment ring 32 has multiple sliding holes 323 that penetrate through it. Each sliding hole 323 corresponds to a plug-in rod 314. The anti-detachment ring 32 is connected to multiple anti-detachment structures 324, each of which corresponds to a plug hole 2121. The anti-detachment structures 324 are used to prevent the portion of the plug-in rod 314 corresponding to the snap-fit ​​groove 3141 from sliding out of the receiving hole 2122.

[0058] In this embodiment, refer to Figures 5 to 9 The anti-detachment ring 32 can be opened around the hinge to laterally engage the support part 211. Multiple sliding holes 323 on the anti-detachment ring 32 penetrate the anti-detachment ring 32 along its thickness direction. Each sliding hole 323 corresponds coaxially to a connecting rod 314, and the inner diameter of the sliding hole 323 allows the connecting rod 314 to pass through. Multiple anti-detachment structures 324 on the anti-detachment ring 32 are columnar, each anti-detachment structure 324 axially aligned with a connecting hole 2121. The anti-detachment structure 324 extends axially to the side of the receiving hole 2122 to prevent the corresponding locking groove 3141 on the connecting rod 314 from sliding out of the receiving hole 2122.

[0059] The anti-detachment ring 32 adds an extra limiting layer to the axial gap between the disc buckle 31 and the connecting part 212. The anti-detachment ring 32 includes a first anti-detachment piece 321 and a second anti-detachment piece 322 that are hinged to each other, allowing the anti-detachment ring 32 to open and close via the hinge. During assembly, it can be laterally enclosed from the support part 211 for easy on-site installation. Multiple through-holes 323 on the anti-detachment ring 32 are respectively provided corresponding to the insertion rod 314, so that the insertion rod 314 can still complete axial insertion and circumferential offset without being blocked by the anti-detachment ring 32 during installation. When the portion of the insertion rod 314 corresponding to the snap-fit ​​groove 3141 rotates and snaps into the receiving hole 2122, the anti-detachment ring 32 moves towards the connecting part 212, and the anti-detachment structure 324 extends into the insertion hole 2121 to prevent the portion of the insertion rod 314 corresponding to the snap-fit ​​groove 3141 from detaching from the receiving hole 2122.

[0060] In one embodiment, the buckle 31 further includes a snap-fit ​​plate 317, which is annular. A connecting cavity 318 is provided on the outer side of the buckle 31, and the connecting cavity 318 is distributed along the outer peripheral surface of the buckle 31. A connecting structure 3171 is connected to the inner sidewall of the snap-fit ​​plate 317. The snap-fit ​​plate 317 has a plurality of snap-fit ​​holes 3172, which are arranged at equal circumferential intervals around the axis of the snap-fit ​​plate 317.

[0061] In this embodiment, refer to Figure 5 , Figure 7 and Figure 8 The snap-fit ​​plate 317 is annular and coaxially fitted onto the outer side of the snap fastener 31, maintaining a coaxial arrangement. A connecting cavity 318 is circumferentially formed on the outer surface of the snap fastener 31. A connecting structure 3171 is connected to the inner wall of the snap-fit ​​plate 317. During assembly, the connecting structure 3171 extends into the connecting cavity 318 and engages with it for positioning. Multiple snap-fit ​​holes 3172 penetrate the snap-fit ​​plate 317 along its thickness direction, and are circumferentially spaced at equal angles around the axis of the snap-fit ​​plate 317.

[0062] The snap fastener 31 is equipped with an annular locking plate 317, which can be coaxially fitted onto the outside of the snap fastener 31, facilitating a coaxial connection. The snap fastener 31 has connecting cavities 318 distributed along its outer circumference, which are engaged by a connecting structure 3171 on the inner wall of the locking plate 317. This allows the locking plate 317 and the snap fastener 31 to be locked together through the interlocking of the connecting cavities 318 and the connecting structure 3171, preventing the locking plate 317 from rotating relative to the snap fastener 31 or coming off. Multiple locking holes 3172 on the locking plate 317 are arranged circumferentially at equal angles around its axis, expanding the connection capacity of the snap fastener 31.

[0063] In one embodiment, the outer side of the card holder 317 extends horizontally beyond the outer side of the passage component 1 as projected in the horizontal direction. The support assembly 2 also includes a plurality of second support rods 23, each second support rod 23 extending into the snap-fit ​​hole 3172 of the portion of the passage assembly 1 projected in the horizontal direction and extending upward; the support assembly 2 also includes a plurality of second protective rods 24, some of the second protective rods 24 are located on the top of the second support rods 23 and are connected end to end in the horizontal direction; the remaining second protective rods 24 are inclined in a direction parallel to the first protective rod 22.

[0064] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The latching plate 317 extends horizontally outward to the outer side of the passage component 1 projected vertically. The portion of the latching plate 317 outside the passage component 1 has a snap-fit ​​hole 3172 for external components to access. Multiple second support rods 23 are straight rods arranged vertically. The bottom end of each second support rod 23 extends into the snap-fit ​​hole 3172 extending beyond the passage component 1 in the latching plate 317 and then upwards. Multiple second protective rods 24 are elongated rods. Four second protective rods 24 are located at the top of the second support rods 23, and are connected end-to-end horizontally to form a closed horizontal frame. The remaining second protective rods 24 are arranged at the same angle as the first protective rods 22, and their ends are connected to the middle sections of adjacent second support rods 23.

[0065] The outer side of the latch plate 317 extends horizontally beyond the passage component 1, providing an access point for supporting the second protective rod 24 arranged on the outside of the passage component 1. The support component 2 includes multiple second support rods 23. Each second support rod 23 extends into the latch plate 317, extending beyond the horizontal projection of the passage component 1 through a snap-fit ​​hole 3172 and upwards. This allows the second support rod 23 to be vertically positioned using the snap-fit ​​hole 3172 of its extended portion, forming another set of vertical fulcrums on the outside of the passage component 1. Four second protective rods 24 are located at the top of the second support rods 23 and are connected end to end horizontally, forming a horizontally closed fence frame at the top of the second support rods 23, providing lateral protection at the top boundary. The remaining second protective rods 24 are inclined in a direction parallel to the first protective rod 22, ensuring that the angle of the outer inclined second protective rod 24 is consistent with the inclination angle of the staircase adapted to the first protective rod 22. This allows the inner first protective rod 22 and the outer second protective rod 24 to extend together along the staircase, improving the safety of the prefabricated temporary passage device.

[0066] The implementation principle of this application embodiment is as follows: the first support rod 21 in the multiple sets of support components 2 is arranged at intervals along the staircase direction and connected to the bottom of the passage component 1, so that the passage component 1 forms the main body for carrying passage. The disc buckle 31 is opened through the hinge end and inserted into the support part 211 from the side. The first disc buckle 31 is placed above the connecting part 212 and the second disc buckle 31 is placed below the connecting part 212. The insertion rod 314 passes through the insertion hole 2121 on the connecting part 212 and the through hole 315 on the second disc buckle 31 in sequence. The disc buckle 31 is rotated so that the snap-fit ​​groove 3141 and the receiving hole 2122 are circumferentially engaged, thereby completing the axial positioning of the disc buckle 31 relative to the connecting part 212. By selecting different snap-fit ​​grooves 3141, the height position of the adjustment component 3 can be adjusted, thereby changing the tilt angle of the first protective rod 22 connected through the connecting hole 316, so that the first protective rod 22 matches the direction of the stair steps. The anti-detachment ring 32 extends into the insertion hole 2121 after the insertion rod 314 is screwed circumferentially into the receiving hole 2122 to prevent the insertion rod 314 from exiting the receiving hole 2122. Tightening the locking member 313 causes the first locking structure 3112 and the second locking structure 3122 to simultaneously grip the support part 211, and the disc buckle 31 is locked in the current position. When adjustment is required, loosening the locking member 313 causes the elastic member 3114 to release its elastic restoring force, causing the locking structure to retract, and the disc buckle 31 can slide again along the axial direction of the support part 211. The outer side is connected to the second support rod 23 and the second protective rod 24 through the extension of the snap-fit ​​plate 317, forming a double-layer protective fence, thereby meeting the diverse construction needs of stair protection occasions with different inclination angles. Compared with the prior art, this application can adjust the inclination angle of the protective rod.

[0067] 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.
