[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0035] In this article, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0037] Reference Figures 1-4 For the first embodiment of the utility model, a telescopic escape passage is proposed, which comprises a first escape pipe 1, a secondary escape pipe 2 slidingly arranged in the first escape pipe 1, the secondary escape pipe 2 being a plurality of secondary escape pipes 2 arranged in sequence, a swing frame 3 swingingly arranged on the secondary escape pipe 2, the swing frame 3 being perpendicular or parallel to the ground after swinging, and a supporting wheel 4 rotatably arranged on the swing frame 3, the supporting wheel 4 being in abutment or out of abutment with the ground after the swing frame 3 swings.

[0038] In this embodiment, the telescopic design of the first escape pipe 1 and the plurality of secondary escape pipes 2 arranged in sequence greatly improves the space utilization efficiency. When not in use, the escape passage can be shrunk to a smaller volume, which is convenient for storage and transportation. For example, in the limited space of a building, it can be easily stored in a corner or a special storage area. When needed, the secondary escape pipe 2 can be pulled out of the first escape pipe 1 to quickly expand into an escape passage with sufficient length, meeting the escape needs of different heights.

[0039] Flexible application of swing frame 3: the swing frame 3 is swingingly arranged on the secondary escape pipe 2, which can be switched between perpendicular and parallel to the ground. This flexibility is of great significance. When the swing frame 3 is swung to be perpendicular to the ground, it can serve as an auxiliary support structure for escape personnel, increasing the stability and safety of the escape passage. For example, when there are many escape personnel or there is a lot of shaking during the escape process, the vertical swing frame 3 can provide additional support force to prevent the escape passage from tilting or shaking too much.

[0040] The support wheels 4 are rotatably arranged on the swing frame 3 and are in contact with or out of contact with the ground after the swing frame 3 swings. When the escape channel is deployed and ready for use, the support wheels 4 are in contact with the ground, which can facilitate the movement and adjustment of the position of the escape channel, so that it is better matched with the building exit or escape platform. At the same time, during the escape process, the support wheels 4 can share part of the weight of the escape personnel, reduce the pressure on the escape pipe, and further improve the stability of the escape channel. Moreover, when the support wheels 4 are not needed, they can be swung to the state of being out of contact with the ground, avoiding unnecessary obstacles during storage or transportation.

[0041] When the telescopic escape pipe is extended, the swing frame 3 plays a key role in providing additional support force for the escape pipe. When the escape pipe is in an extended state, especially in the case of a long length, the middle part of the pipe may face the risk of collapse due to its own gravity and the weight of the escape personnel. The presence of the swing frame 3 effectively shares part of the weight, reducing the pressure on the middle part of the pipe, thereby greatly reducing the possibility of collapse.

[0042] This additional support force is crucial to the safety of the escape personnel. If the middle part of the escape pipe collapses, not only will it hinder the escape channel, but it may also cause injuries or even entrapment of the escape personnel. The support function of the swing frame 3 ensures the stability of the escape channel, allowing the escape personnel to quickly evacuate in a safe and reliable environment.

[0043] Further, the support frame 5 is provided, the first escape pipe 1 is arranged on the support frame 5, the support frame 5 is arranged to be raised and lowered relative to the ground, the crankshaft 6 is rotatably arranged on the support frame 5, and the ground support wheel 7 is rotatably arranged on the crankshaft 6. The crankshaft 6 is located on the ground, and after the crankshaft 6 rotates, the support frame 5 is raised and lowered relative to the ground, driving the first escape pipe 1 to be raised and lowered relative to the ground.

[0044] In this embodiment, the first escape pipe 1 is arranged on the support frame 5, which is arranged to be raised and lowered relative to the ground. The support frame 5 is raised and lowered by the rotation of the crankshaft 6, thereby realizing the raising and lowering of the first escape pipe 1 relative to the ground. This design enables the telescopic escape channel to adjust the height according to different tunnel heights and terrain conditions. This height-adjustable function enables the escape channel to adapt to various complex emergency situations. By adjusting the height of the support frame 5, the effectiveness of the escape channel can be ensured, which greatly improves the versatility of the escape channel and enables it to play a role in different scenarios, providing escape opportunities for more people.

[0045] The support frame 5 provides stable support for the first escape tube 1. During the escape process, the weight of the escape personnel and possible external forces can exert pressure on the escape passage. The presence of the support frame 5 can distribute these pressures, ensuring that the escape passage does not tilt or collapse due to uneven stress. At the same time, the rotation of the crankshaft 6 can smoothly control the lifting and lowering of the support frame 5, avoiding the danger of sudden lifting and lowering actions to the escape passage and the escape personnel. By adjusting the height of the support frame 5, the escape passage can maintain a suitable angle with the ground, reducing the risk of falling when entering the passage for the escape personnel. In addition, the stable support structure can also prevent the escape passage from shaking or shifting during use, providing a safer and more reliable escape environment for the escape personnel. In emergency situations, safety is of utmost importance, and this design can greatly improve the success rate of escape.

[0046] Further, it further comprises guide wheels 8, which are provided on the secondary escape tubes 2 and the first escape tube 1, and are used to guide the extension and retraction of the multiple secondary escape tubes 2.

[0047] In this embodiment, the guide wheels 8 are provided on the secondary escape tubes 2 and the first escape tube 1, and their main function is to guide the extension and retraction of the multiple secondary escape tubes 2. In actual use, when the escape passage needs to be deployed, the guide wheels 8 can reduce the frictional resistance between the secondary escape tubes 2, making each segment of the secondary escape tube 2 more smoothly extend or retract from the first escape tube 1. Compared with the case without guide wheels 8, this design greatly improves the extension and retraction efficiency of the escape passage, saving valuable time in emergency situations. The presence of the guide wheels 8 makes it easier for the operator to deploy or retract the escape passage. Whether operated by professional rescue personnel or used by ordinary people in emergency situations, the guide wheels 8 can reduce the operation difficulty and improve the convenience of operation. For example, in the process of emergency escape, people can deploy the escape passage more quickly, gaining more time and opportunity for escape. During the extension and retraction of the secondary escape tubes 2, the guide wheels 8 can avoid direct contact and friction between the escape tubes, thereby reducing the wear of the escape tubes. This protection is crucial for extending the service life of the escape passage. After long-term storage and multiple uses, the guide wheels 8 can ensure that the escape tubes still maintain good performance and structural integrity, reducing failures and damage caused by wear.

[0048] Further, it further comprises a clamping piece 9, which is provided on the secondary escape tubes 2, and the swing frame 3 is clamped by the clamping piece 9 when it is parallel to the ground.

[0049] In this embodiment, when the swing frame 3 is swung to be parallel to the ground, the clamping piece 9 can clamp it. This function is very important when the escape channel is not in use and needs to be stored. By fixing the swing frame 3 with the clamping piece 9, the structure of the entire escape channel can be ensured to be more stable, avoiding accidental swinging of the swing frame 3 during transportation and storage, which can cause damage or occupy too much space. For example, when the escape channel is placed on a vehicle for transportation, the clamping piece 9 can prevent the swing frame 3 from shaking, ensuring the safety of the transportation process.

[0050] The presence of the clamping piece 9 makes the escape channel more compact in the storage state, facilitating management and storage. Whether placed in a warehouse or on an emergency rescue vehicle, the neatly fixed escape channel can save space and improve storage efficiency. At the same time, it is also convenient for rescue personnel to quickly find and take out the escape channel in an emergency, improving the emergency response speed. During transportation and storage, if the swing frame 3 is not fixed, it may accidentally expand due to vibration, collision, etc. This not only may damage the escape channel itself, but also may pose a danger to the surrounding personnel and objects. The role of the clamping piece 9 is to prevent such accidents from happening, improving the safety of the escape channel in the non-use state.

[0051] Further, the clamping piece 9 includes a first body 901 arranged on the secondary escape pipe 2, and a second body 902 slidingly arranged on the first body 901, and a clamping space is formed between the first body 901 and the second body 902.

[0052] In this embodiment, the clamping piece 9 is arranged on the secondary escape pipe 2 by the first body 901, and the second body 902 is slidingly arranged on the first body 901, and a clamping space is formed between the two. This design allows the clamping space to be flexibly adjusted according to actual needs. In different use scenarios, the size of the swing frame 3 may vary, and the adjustable clamping space can better adapt to swing frames 3 of various sizes, improving the versatility and applicability of the clamping piece 9. When installing or dismounting the swing frame 3, the position of the second body 902 on the first body 901 can be adjusted to expand or reduce the clamping space, making the operation more convenient and efficient. This flexible adjustment reduces the difficulty in the installation and dismounting process, improving work efficiency. The clamping space formed between the first body 901 and the second body 902 can tightly clamp the swing frame 3, enhancing the clamping effect. During the use of the escape channel, the swing frame 3 needs to withstand certain pressure and impact force, and the tight clamping of the clamping space can ensure that the swing frame 3 does not loosen or fall off, improving the stability and safety of the escape channel. The presence of the clamping space can effectively prevent the swing frame 3 from swinging unexpectedly. In an emergency, any accidental swinging can pose a danger to the escape personnel, and the clamping action of the clamping piece 9 can avoid such situations, providing reliable protection for the escape personnel.

[0053] Further, the second body 902 has a sliding part, and the second body 902 has a guide surface 903 that abuts against one side of the guide wheel 8 after the secondary escape pipe 2 slides, and the guide wheel 8 pushes the second body 902 to slide, and after the second body 902 slides relative to the first body 901, the swing frame 3 and the clamping piece 9 are uncoupled.

[0054] In this embodiment, when the secondary escape pipe 2 slides, the guide surface 903 of the second body 902 abuts against one side of the guide wheel 8. This design enables the guide wheel 8 to push the second body 902 to slide during the extension and retraction of the pipe. Through this linkage, when it is necessary to deploy the escape passage, the sliding of the secondary escape pipe 2 will automatically trigger the movement of the second body 902, thereby realizing the automatic uncoupling of the swing frame 3 and the clamping piece 9. This function greatly improves the efficiency of the escape passage in emergency situations, and the swing frame 3 can be quickly unlocked without manual intervention, which saves valuable time for the escape personnel. The automatic unlocking function makes the deployment process of the escape passage more coherent. In an emergency, people are often in a state of tension and panic, and complex operation steps may cause delays and errors. This automatic unlocking design can ensure that the components of the escape passage work smoothly in coordination, reducing the complexity of the operation and improving the success rate of escape.

[0055] The automatic uncoupling mode reduces the safety risks caused by human errors. In the traditional clamping structure, the clamping piece 9 needs to be manually unlocked, which may cause problems due to improper or negligent operation. Through the interaction between the guide wheel 8 and the second body 902 to achieve automatic unlocking, the influence of human factors can be avoided, and the safety and reliability of the escape passage are improved.

[0056] Further, it further includes a resilient member 10, one end of the resilient member 10 acting on the first body 901, and the other end acting on the second body 902, providing a force for reducing the clamping space.

[0057] In this embodiment, one end of the resilient member 10 acts on the first body 901, and the other end acts on the second body 902, providing a force for reducing the clamping space. This design enables the clamping piece 9 to continuously maintain a certain clamping force when clamping the swing frame 3, ensuring that the swing frame 3 will not easily loosen or disengage. During the use of the escape passage, it may be affected by various external forces, such as shaking and vibration, etc. The existence of the resilient member 10 can effectively resist these external forces and enhance the stability of the clamping. A stable clamping state is crucial for the safety of the escape passage. If the swing frame 3 loosens accidentally during use, it may cause the structure of the escape passage to be unstable, increasing the risk to the escape personnel. The action of the resilient member 10 can reduce this risk and provide a more reliable escape route for the escape personnel.

[0058] The elastic properties of the elastic member 10 enable the clamping member 9 to automatically adapt to different working conditions. When the size or shape of the swing frame 3 changes slightly, the elastic member 10 can adjust the clamping force through its own elastic deformation, ensuring that the clamping effect is always good. This self-adaptive ability enables the escape passage to maintain stable performance in various situations, improving the versatility and reliability of the equipment.

[0059] During the extension and retraction of the escape passage, the elastic member 10 also plays a certain buffering role. When the secondary escape tube 2 slides, it may generate a certain impact force on the clamping member 9, and the elastic member 10 can absorb part of the impact force, reducing damage to the clamping member 9 and other components. At the same time, the buffering effect can also reduce noise and vibration, improving the comfort of using the escape passage.

[0060] Further, the secondary escape tube 2 is provided with a guide wheel 8 at both ends, and the guide wheels 8 of adjacent two secondary escape tubes 2 abut after the adjacent two secondary escape tubes 2 extend to the longest.

[0061] In this embodiment, the guide wheel 8 is provided at both ends of the secondary escape tube 2, and the guide wheels 8 abut after the adjacent two secondary escape tubes 2 extend to the longest. This design makes the guide wheel 8 not only play a guiding role in the extension and retraction process, but also provide stable connection in the extended state. During the use of the escape passage, the guiding function of the guide wheel 8 ensures that the secondary escape tube 2 can be smoothly extended and retracted, reducing the possibility of friction and jam. When extended to the longest state, the guide wheels 8 of adjacent secondary escape tubes 2 abut, forming a stable support structure to prevent the escape tube from shaking or misplacing during use.

[0062] The abutment of the guide wheel 8 increases the overall stability of the escape passage. In an emergency, escape personnel need a stable and reliable escape route. The abutment of adjacent guide wheels 8 enables the escape passage to maintain a stable shape when bearing the weight of personnel and external pressure, reducing the dangers caused by shaking or deformation. This stable structure provides a safer escape environment for escape personnel, improving the success rate of escape.

[0063] The abutment of the guide wheel 8 plays a role in limiting the extension length of the secondary escape tube 2. In actual use, if the secondary escape tube 2 is excessively extended, it may cause instability or damage. The abutment of adjacent guide wheels 8 can effectively prevent this from happening, ensuring that the escape passage is used within a safe range. This function of limiting the extension length protects the structural integrity of the escape passage, prolonging the service life of the equipment.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
