Description

Technical Field

[0001] This utility model belongs to the field of emergency evacuation route technology, and in particular relates to an emergency evacuation route guardrail with a foldable and retractable structure. Background Technology

[0002] Emergency evacuation routes are dedicated paths within buildings designed to ensure the rapid and safe evacuation of personnel during emergencies such as fires and earthquakes. Their core function is to ensure unobstructed access for life safety through scientific planning and standardized management. Emergency evacuation routes encompass evacuation corridors, safety exits, evacuation staircases, and fire truck access routes within buildings. They are continuous paths connecting dangerous and safe areas, and their design must meet requirements for personnel density, evacuation distance, and passage efficiency. For example, the straight-line distance from any point in a public building to the nearest safety exit should not exceed 30 meters. High-rise buildings must also have refuge floors, and the vertical distance from the first refuge floor to the fire truck access area should not exceed 50 meters. The routes must be decorated with fire-resistant and smoke-proof materials, such as fire-retardant coatings and flame-retardant boards, and equipped with emergency lighting and evacuation signs. Evacuation doors should be swing doors that open in the direction of evacuation; revolving doors, roller shutters, and other types that impede escape are prohibited.

[0003] Most foldable guardrails on the market currently lack a positioning structure, meaning they can only be placed on the ground and cannot be fixed in place. Alternatively, they require auxiliary structures for fixed installation, which is quite cumbersome. Emergency evacuation routes are typically used by densely populated areas, so the guardrails installed in them need to be very stable and have a certain degree of impact resistance to meet the requirements. Therefore, it is necessary to provide solutions to the above problems. Utility Model Content

[0004] The technical content of this utility model is to provide an emergency evacuation passage guardrail with a foldable and retractable structure.

[0005] To address the aforementioned problems, this utility model provides an emergency evacuation passage guardrail with a foldable and retractable structure, including mounting bases. Two sets of mounting bases are configured, with two sets of guardrail structures symmetrically installed between them. Hinged seats are installed on both sides of each guardrail structure, with limit blocks installed on the sides of the hinged seats. Limit grooves are formed at the bottom of the sides of each mounting base. Fixing plates are installed on both sides of the bottom of each mounting base, with positioning tubes installed on the fixing plates and positioning rods installed within the positioning tubes. Anti-collision plates are installed on the sides of each mounting base via four sets of fixing rods, with springs installed on the sides of the anti-collision plates. A locking block is installed on the front of the left-side mounting base, and a locking plate is installed on the front of the right-side mounting base.

[0006] As a further solution of this utility model, the opposite side of the two sets of mounting seats is the inner side of the mounting seats. Four sets of hinge seats are installed at the four ends of both sides of one set of guardrail structure. The top two sets of hinge seats are fixedly connected to the inner top of the two sets of mounting seats. The limiting block is set in the limiting groove opened at the bottom of the inner side of the mounting seat. Two sets of limiting grooves are symmetrically arranged at the bottom of the inner side of the mounting seat. The limiting block is fixedly installed on the side of the hinge seats at the bottom of both sides of the guardrail structure. The limiting block and the limiting groove are set as a matching T-shaped structure so that the limiting block cannot be disengaged from the limiting groove.

[0007] As a further solution of this utility model, the four ends of the hinge seat and the guardrail structure are hinged. The guardrail structure is assembled from multiple sets of intersecting connecting rods. The two sets of connecting rods connected together are rotatably connected by a pivot, so that the overall length of the guardrail structure is adjustable.

[0008] As a further solution of this utility model, two sets of mounting holes are symmetrically opened on the fixing plate, and the positioning tube is fixedly installed in them. The top of the positioning tube is higher than the top of the fixing plate, and the bottom of the positioning tube is flush with the bottom of the fixing plate. The outer side of the positioning rod installed inside the positioning tube and the inner side of the positioning tube are provided with matching threaded groove structures. The top of the positioning rod is set as a hexagonal structure to allow rotation.

[0009] As a further solution of this utility model, the width of the anti-collision plate is greater than the width of the mounting base, and through holes are provided at the four corners of the anti-collision plate. The fixing rods are installed in the holes, the diameter of the fixing rods is the same as the inner diameter of the through holes, and the diameters of the two ends of the fixing rods are greater than the inner diameter of the through holes. Thus, the anti-collision plate is installed by four sets of fixing rods.

[0010] As a further solution of this utility model, two sets of springs are symmetrically installed between the anti-collision plate and the mounting base. Both ends of the springs are fixedly connected to the anti-collision plate and the mounting base, thereby fixing the anti-collision plate laterally through the springs.

[0011] As a further solution of this utility model, the card block is set as a T-shaped structure, and the locking plate is rotatably installed in the center of the front of a set of mounting seats on the right side by a fixing pin. The height of the card block and the locking plate are the same. The lower right end of the locking plate is provided with a card slot that matches the card block. The length of the locking plate matches the overall width of the guardrail structure after it is folded up. The two sets of mounting seats can be locked together by the combination of the locking plate and the card block.

[0012] Compared with related technologies, the emergency evacuation passage railing with a foldable and retractable structure provided by this utility model has the following beneficial effects:

[0013] 1. This utility model improves the overall strength of the device by installing two sets of symmetrical guardrail structures between two sets of mounting seats. It can withstand a certain degree of impact when used in emergency evacuation routes. The guardrail structure can be telescopically adjusted to meet the needs of actual use. Fixed plates are installed on both sides of the bottom of the mounting seats, and positioning tubes are installed on the fixed plates. Positioning rods are installed in the tubes. By rotating the positioning rods, the positioning rods can be inserted into the positioning holes set in the ground. Thus, the mounting seats are fixedly installed on the ground through four sets of positioning rods, thereby fixing the entire device and making the device have good stability during use.

[0014] 2. This utility model features a crash plate mounted on the side of the mounting base via a spring and a fixing rod. The fixing rod ensures the crash plate is stably mounted on the side of the mounting assembly, while the spring keeps the crash plate stable in the absence of external force. The width of the crash plate is greater than the width of the mounting base. When the crash plate is subjected to a lateral impact, the spring is compressed, and the crash plate moves along the fixing rod, thereby dispersing the impact force. By setting the crash plate, the mounting base can be protected to a certain extent, preventing damage due to impact. Attached Figure Description

[0023] Please refer to the following: Figure 1-6 An emergency evacuation passage guardrail with a foldable and retractable structure includes a mounting base 1, which is configured as two sets. Two sets of guardrail structures 2 are symmetrically installed between the two sets of mounting base 1. Hinged seats 3 are installed on both sides of the guardrail structures 2. Limiting blocks 4 are installed on the sides of the hinged seats 3. Limiting grooves 5 are opened at the bottom of the sides of the mounting base 1. Fixing plates 6 are installed on both sides of the bottom of the mounting base 1. Positioning tubes 7 are installed on the fixing plates 6. Positioning rods 8 are installed in the positioning tubes 7. Anti-collision plates 10 are installed on the sides of the mounting base 1 through four sets of fixing rods 9. Springs 11 are installed on the sides of the anti-collision plates 10. A locking block 12 is installed on the front of the left set of mounting base 1, and a locking plate 13 is installed on the front of the right set of mounting base 1.

[0024] Preferably, the inner side of the two sets of mounting seats 1 is the opposite side of the mounting seat 1. Four sets of hinge seats 3 are installed at the four ends of both sides of a set of guardrail structures 2. The top two sets of hinge seats 3 are fixedly connected to the inner top of the two sets of mounting seats 1. The limiting block 4 is set in the limiting groove 5 opened at the bottom of the inner side of the mounting seat 1. Two sets of limiting grooves 5 are symmetrically arranged at the bottom of the inner side of the mounting seat 1. The limiting block 4 is fixedly installed on the side of the hinge seat 3 at the bottom of both sides of the guardrail structure 2. The limiting block 4 and the limiting groove 5 are set as a matching T-shaped structure, so that the limiting block 4 cannot be separated from the limiting groove 5, thereby limiting the hinge seat 3 at the bottom of the guardrail structure 2 and preventing it from being separated from the mounting seat 1 laterally.

[0025] Preferably, the four ends of the hinge seat 3 and the guardrail structure 2 are hinged. The guardrail structure 2 is assembled from multiple sets of intersecting connecting rods. The two sets of connecting rods connected together are rotatably connected by a pivot, so that the overall length of the guardrail structure 2 is adjustable. When adjusting the overall length of the guardrail structure 2, the distance between the two sets of mounting seats 1 can be adjusted. At this time, the two sets of hinge seats 3 at the bottom of both sides of the guardrail structure 2 will slide relative to the two sets of mounting seats 1. The limiting block 4 slides synchronously in the vertical limiting groove 5 to ensure the stability of the hinge seat 3, thereby ensuring the stability of the guardrail structure 2. By symmetrically installing two sets of guardrail structures 2 between the two sets of mounting seats 1, this device can improve the overall strength of the device and withstand a certain degree of impact when used in emergency evacuation passages.

[0026] Preferably, two sets of mounting holes are symmetrically opened on the fixing plate 6, and the positioning tube 7 is fixedly installed in them. The top of the positioning tube 7 is higher than the top of the fixing plate 6, and the bottom of the positioning tube 7 is flush with the bottom of the fixing plate 6. The positioning rod 8 installed inside the positioning tube 7 has a matching threaded groove structure on the outer side and the inner side of the positioning tube 7. The top of the positioning rod 8 is set as a hexagonal structure so as to be rotated, so that the positioning rod 8 can move along the positioning tube 7, and then the positioning rod 8 can be inserted into the positioning hole set in the ground. Thus, the mounting base 1 is fixedly installed on the ground by the four sets of positioning rods 8, thereby fixing the entire device and making the device have good stability during use.

[0027] Preferably, the width of the anti-collision plate 10 is greater than the width of the mounting base 1. Through holes are provided at the four corners of the anti-collision plate 10, and fixing rods 9 are placed in them. The diameter of the fixing rods 9 is the same as the inner diameter of the through holes, and the diameters of the two ends of the fixing rods 9 are greater than the inner diameter of the through holes. Thus, the anti-collision plate 10 is installed by four sets of fixing rods 9, so that the anti-collision plate 10 can only move laterally along the fixing rods 9, and the anti-collision plate 10 cannot detach from the fixing rods 9.

[0028] Preferably, two sets of springs 11 are symmetrically installed between the anti-collision plate 10 and the mounting base 1. Both ends of the springs 11 are fixedly connected to the anti-collision plate 10 and the mounting base 1, thereby fixing the anti-collision plate 10 laterally through the springs 11. When there is no external force, the anti-collision plate 10 maintains a constant distance from the mounting base 1 under the elastic force of the springs 11. When the anti-collision plate 10 is subjected to a lateral impact, the springs 11 are in a compressed state, and the anti-collision plate 10 moves along the fixed rod 9, thereby dispersing the impact force. By setting the anti-collision plate 10, the mounting base 1 can be provided with a certain degree of protection to prevent the mounting base 1 from being damaged by impact.

[0029] Preferably, the locking block 12 is configured as a T-shaped structure, and the locking plate 13 is rotatably installed in the center of the front of the right set of mounting seats 1 by a fixing pin. The locking block 12 and the locking plate 13 have the same height. The lower right end of the locking plate 13 has a slot that matches the locking block 12. The length of the locking plate 13 matches the overall width of the guardrail structure 2 after it is stored. When storing the device, push the two sets of mounting seats 1 closer to each other to fold and store the guardrail structure 2. At this time, the locking plate 13 can be rotated to make the locking plate 13 horizontal to the left, so that the locking block 12 enters the slot on the locking plate 13, thereby connecting the locking plate 13 and the locking block 12 together, thereby connecting the two sets of mounting seats 1 together, thus fixing the overall size of the device for storage. When it is necessary to unfold the device, rotate the locking plate 13 to disengage it from the locking block 12.
