Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of escape routes, and more specifically, to an escape route pipe section that is easy to connect. Background Technology
[0002] In emergencies such as earthquakes, fires, and building collapses, rapidly establishing safe escape routes is crucial to ensuring the safety of trapped individuals. As a core component of temporary emergency passages, the connection efficiency and stability of escape route sections directly determine the speed of construction and the safety of use.
[0003] Currently, most escape tunnel sections on the market are single tubular structures, lacking specially designed quick-connect and fixing mechanisms. During emergency setup, connecting sections often relies on traditional methods such as rope binding and bolt fixing, which are not only cumbersome and require multiple people to complete, but also difficult to achieve precise connections in a short time. A more prominent problem is the poor fixing effect of existing sections: after connection, due to the lack of a reliable locking structure, the sections are prone to loosening or even detachment due to vibration or external impact, leading to tunnel breakage and seriously threatening the safety of escapees. In complex terrain (such as sloping ground or gaps in rubble), this problem of insecure fixing is even more pronounced, easily causing overall tunnel instability.
[0004] Furthermore, in emergency situations, the construction of escape routes is time-sensitive. Traditional pipe connection methods require significant time for adjusting positions and fastening components, delaying rescue progress. Simultaneously, some pipe sections suffer from poor compatibility due to inconsistent interface sizes, making it difficult to quickly assemble different types of pipes, further limiting the flexible combination and extension of the escape route. Therefore, given the specific characteristics of emergency escape scenarios, there is an urgent need for an escape route pipe section with rapid connection capabilities and reliable stability to address the shortcomings of existing products in terms of connection efficiency and stability. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an escape passage pipe segment that is easy to connect, solving the technical problem that the connection between pipe segments in the prior art often relies on traditional methods such as rope binding and bolt fixing, which is not only cumbersome to operate and requires multiple people to cooperate to complete, but also difficult to achieve accurate connection in a short time.
[0006] According to one aspect, at least one embodiment of this disclosure provides an escape route segment that is easy to connect, comprising:
[0007] A pair of pipe segments and a docking assembly, wherein the docking assembly is disposed at both ends of the pipe segments;
[0008] The docking assembly includes an outer docking groove, which is formed at one end of the main body of the pipe segment, and an inner docking groove is formed at the other end of the main body of the pipe segment.
[0009] Several slots are provided on the inner circumference end face of the outer docking groove, and several locking blocks are provided on the main body end face of the pipe section at the other end. The diameter of the outer docking groove matches that of the inner docking groove.
[0010] As a further technical solution, a reinforcement connection component is also included. The reinforcement connection component includes several splicing grooves, which open and close at one end of the pipe section body, and several splicing blocks are provided on the inner end face of the docking outer groove.
[0011] As a further technical solution, a first reinforcing groove is provided on the outer surface of both the splicing block and the main body of the pipe segment, and a second reinforcing groove is provided on the inner end face of the splicing groove, wherein the internal dimensions of the first reinforcing groove and the second reinforcing groove are matched.
[0012] As a further technical solution, insertion holes are provided in the first reinforcement groove and the second reinforcement groove. A splicing plate is inserted into the first reinforcement groove, and a pair of insertion blocks are provided on the bottom surface of the splicing plate. The insertion blocks are inserted into the insertion holes.
[0013] As a further technical solution, both the card slot and the card block have a toothed structure.
[0014] As a further technical solution, notches are provided on both sides of the first and second reinforcement grooves, and pry grooves are provided on both ends of the bottom surface of the splicing plate, with the pry grooves corresponding to the notches.
[0015] As a further technical solution, the outer surface of the splicing plate is an arc-shaped structure, and the curvature of the splicing plate surface matches the curvature of the outer wall of the pipe section body.
[0016] As a further technical solution, the lower end face of the insertion block is flush with the inner wall of the main body of the pipe section.
[0017] The beneficial effects of the embodiments disclosed herein are as follows:
[0018] 1. In this disclosure, the docking assembly solves the problems of cumbersome and difficult-to-quickly docking in traditional connection methods through the fitting of grooves and the engagement of teeth. The precise matching of the outer and inner grooves ensures the coaxiality of the pipe sections and avoids abrupt changes in the inner diameter of the channel; the toothed grooves and locking blocks mesh with each other, achieving initial fixation without tools and preventing the pipe sections from loosening or rotating. This design allows a single person to quickly complete the docking, significantly shortening the time required to build an escape route, buying precious escape time for trapped personnel in emergencies, while ensuring basic stability after docking.
[0019] 2. In this disclosure, the reinforced connection assembly solves the problem of insufficient connection strength of pipe sections through a multi-locking structure. The splicing blocks and splicing grooves restrict radial displacement, the first and second reinforcing grooves fit snugly with the splicing plate to increase the contact area, and the insert blocks and insertion holes prevent the splicing plate from falling off, forming a three-dimensional reinforcement system. The arc-shaped splicing plate smoothly transitions to the outer wall of the pipe section, avoiding obstruction of personnel passage. This design significantly improves the impact resistance of the connection parts, ensuring that the escape route does not loosen or fall off in complex environments, providing a safe and reliable passage guarantee for escaping personnel.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-4 As shown, it illustrates an escape route segment that is easy to connect according to an embodiment of the present disclosure, comprising:
[0033] A pair of pipe segment bodies 1 and a docking assembly 2, wherein the docking assembly 2 is disposed at both ends of the pipe segment body 1;
[0034] The docking assembly 2 includes an outer docking groove 2-1, which is formed at one end of the pipe segment body 1, and an inner docking groove 2-2 is formed at the other end of the pipe segment body 1.
[0035] A number of slots 2-3 are provided on the inner circumference of the outer docking groove 2-1, and a number of locking blocks 2-4 are provided on the end face of the main body 1 of the pipe section at the other end. The diameter of the outer docking groove 2-1 matches that of the inner docking groove 2-2.
[0036] In some examples, to achieve rapid splicing of pipe segments, a docking component 2 is designed. This component includes an outer docking groove 2-1 at one end of the pipe segment body 1, which is an annular groove with smooth walls, and an inner docking groove 2-2 at the other end, which is an annular concave groove that precisely matches the diameter of the outer docking groove 2-1, ensuring a tight fit. The slots 2-3 on the inner end face of the outer docking groove 2-1 are evenly distributed around the circumference and their shape matches the locking block 2-4 at the other end of the pipe segment body 1. The locking block 2-4 is made of rigid material and will not deform.
[0037] During splicing, the inner groove 2-2 of one pipe segment body 1 is aligned with the outer groove 2-1 of the other pipe segment body 1. Axial pushing causes the inner groove 2-2 to insert into the outer groove 2-1. At this time, the locking block 2-4 enters the outer groove 2-1 along with the inner groove 2-2. When the locking block 2-4 moves to the locking groove 2-3 position, circumferential positioning is achieved, preventing relative rotation of the two pipe segments. The fitting structure of the outer groove 2-1 and the inner groove 2-2 ensures coaxiality after splicing, avoiding misalignment that could lead to abrupt changes in the channel's inner diameter. The cooperation between the locking groove 2-3 and the locking block 2-4 provides fixation, preventing the pipe segments from separating under axial force.
[0038] This component can be initially assembled without tools. The assembly process of blocks 2-4 is labor-saving and ensures a firm fit. It is suitable for the rapid construction of escape routes in emergency situations, laying the foundation for subsequent reinforcement and ensuring the convenience and initial stability of the route assembly.
[0039] like Figures 1-4As shown, this embodiment also includes a reinforcing connection component 3, which includes several splicing grooves 3-1. The splicing grooves 3-1 open and close at one end of the pipe segment body 1. Several splicing blocks 3-2 are provided on the inner end face of the docking outer groove 2-1. The splicing blocks 3-2 and the outer surface of the pipe segment body 1 are both provided with a first reinforcing groove 3-3. The inner end face of the splicing groove 3-1 is provided with a second reinforcing groove 3-4. The internal dimensions of the first reinforcing groove 3-3 and the second reinforcing groove 3-4 are matched. Insertion holes 3-5 are provided in the first reinforcing groove 3-3 and the second reinforcing groove 3-4. A splicing plate 3-6 is inserted into the first reinforcing groove 3-3. A pair of insertion blocks 3-7 are provided on the bottom surface of the splicing plate 3-6. The insertion blocks 3-7 are inserted into the insertion holes 3-5.
[0040] In some examples, to achieve a high-strength locking effect for pipe segment splicing, a reinforced connection component 3 is designed. This component includes splicing grooves 3-1 evenly distributed around the circumference at one end of the pipe segment body 1, corresponding one-to-one with splicing blocks 3-2 on the inner side of the outer groove 2-1 at the other end. The shape of the splicing blocks 3-2 is adapted to the splicing grooves 3-1, allowing them to be fully embedded in the grooves to form radial positioning. The splicing blocks 3-2 and the first reinforced groove 3-3 on the outer surface of the pipe segment body 1 are rectangular grooves. The second reinforced groove 3-4 on the inner end face of the splicing groove 3-1 has the same dimensions as the first reinforced groove 3-3. After splicing, the two form a complete rectangular groove. The insertion hole 3-5 penetrates the bottom of the first reinforced groove 3-3 and the second reinforced groove 3-4, and mates with the insertion block 3-7 on the bottom surface of the splicing plate 3-6.
[0041] The splicing plate 3-6 is a rectangular metal plate, and the insert block 3-7 is vertically fixed to the bottom of the plate, matching the position and size of the insertion hole 3-5. After the initial splicing of the two pipe sections assembly 2 is completed, the splicing block 3-2 is embedded in the splicing groove 3-1, the first reinforcing groove 3-3 is aligned with the second reinforcing groove 3-4, and the splicing plate 3-6 is inserted into the aligned groove, so that the insert block 3-7 is fully inserted into the insertion hole 3-5. At this time, the splicing plate 3-6 simultaneously fits against the inner walls of the first reinforcing groove 3-3 and the second reinforcing groove 3-4, and the splicing plate 3-6 and the pipe section body 1 are further fixed by bolts or pins.
[0042] The fit between the splicing block 3-2 and the splicing groove 3-1 restricts the radial displacement of the pipe section. The fit between the first reinforcing groove 3-3, the second reinforcing groove 3-4 and the splicing plate 3-6 increases the contact area and disperses external forces. The fit between the insert block 3-7 and the insertion hole 3-5 prevents the splicing plate 3-6 from falling off, forming multiple layers of fixation. This component enhances the structural strength of the pipe section splice through mechanical locking, and can withstand axial tensile force and radial pressure, ensuring the structural stability of the escape route in emergency situations and meeting the safety requirements of complex environments.
[0043] For example, such as Figure 1As shown, both the slot 2-3 and the block 2-4 have a toothed structure.
[0044] In some examples, the toothed structure of the slot 2-3 and the block 2-4 meshes with each other. This structure increases the contact area and friction between the two. After the block 2-4 springs into the slot 2-3, it enhances the circumferential positioning stability. The toothed meshing makes the docking of the two pipe sections more precise, avoids relative rotation, improves the stability of the initial splicing, and meets the reliability requirements of the escape tunnel.
[0045] For example, such as Figure 4 As shown, the first reinforcing groove 3-3 and the second reinforcing groove 3-4 are provided with notches 4 on both sides of the inner end face, and the splicing plate 3-6 is provided with pry grooves 5 on both ends of the bottom surface. The pry grooves 5 and the notches 4 are positioned corresponding to each other.
[0046] In some examples, the notches 4 of the first reinforcement groove 3-3 and the second reinforcement groove correspond to the pry slots 5 of the splicing plate 3-6, forming an operating space. During disassembly, tools can be inserted into the pry slots 5 and notches 4 to easily pry the splicing plate 3-6 away from the groove, facilitating pipe section disassembly and recovery. The cooperation between the notches 4 and pry slots 5 makes loading and unloading the splicing plate 3-6 easier, especially in emergency situations, enabling quick operation and improving the practicality of the device.
[0047] For example, such as Figure 1 As shown, the outer surface of the splicing plate 3-6 is an arc-shaped structure, and the curvature of the splicing plate 3-6 surface matches the curvature of the outer wall of the pipe section body 1.
[0048] In some examples, the arc-shaped structure on the outer surface of the splicing plate 3-6 matches the curvature of the outer wall of the main pipe section 1, forming a smooth transition surface after fitting. This avoids protrusions at the splicing point, preventing personnel from tripping during escape, while also enhancing the fit between the splicing plate 3-6 and the pipe section, making the distribution of external forces more uniform, and improving the aesthetics and safety of the overall structure.
[0049] For example, such as Figure 2 As shown, the lower end face of the insert 3-7 is flush with the inner wall of the pipe section body 1.
[0050] In some examples, the lower end face of the insert 3-7 is flush with the inner wall of the pipe section to avoid forming a protrusion inside the pipe section. This does not obstruct personnel passage or the transport of goods, ensures a smooth escape route, and prevents scratches to personnel or the accumulation of debris. The flush design also allows for more even stress distribution on the insert 3-7, extending its service life and ensuring stable reinforcement.
[0051] In practical use: Connect the two pipe sections 1 together, aligning the outer groove 2-1 of one pipe section with the inner groove 2-2 of the other. Push axially until the toothed locking block 2-4 is fully embedded in the groove 2-3, completing the initial positioning and preventing relative rotation and axial separation. At this time, the splicing block 3-2 is embedded in the corresponding splicing groove 3-1, and the first reinforcing groove 3-3 is aligned with the second reinforcing groove 3-4. Insert the splicing plate 3-6 into the aligned groove, so that the insert block 3-7 is accurately inserted into the insertion hole 3-5, with the arc-shaped plate surface fitting against the outer wall of the pipe section. When disassembly is required, insert the tool into the notch 4 and the pry groove 5 to pry the splicing plate 3-6, separating the insert block 3-7 from the insertion hole 3-5. Then pull the pipe section in the opposite direction to disengage the locking block 2-4 from the groove 2-3, completing the disassembly.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
