The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Example 1

As shown in fig. 1, 2 and 7, the present utility model provides a portable escape passage including: a plurality of C-shaped bistable composite material pipes 1 are sleeved inside and outside each other in sequence to form a single-section escape passage 2; a plurality of first annular lining pieces 3 are in interval butt joint in the single-section escape passage 2; the first annular outer locking pieces 4 are sleeved outside the single-section escape passage 2 at intervals.

Specifically, due to the extensibility of the bistable large-deformation material, when the escape passage is not used, the C-shaped bistable composite material pipe 1 is rolled up into a roll shape along the length direction after being unfolded into a plane along the position of the C-shaped opening 11, so that the space volume is effectively reduced, and the escape passage can be plugged into a knapsack to be carried about; when the escape passage is needed, the user expands the roll shape into a plane, and then rolls up the plane along the width direction into a C-shaped bistable composite material tube 1; because of the existence of the C-shaped opening 11, a plurality of C-shaped bistable composite material pipes 1 can be sequentially coated from inside to outside to form a single-section escape passage 2 with multiple layers; in order to prevent the C-shaped opening 11 from being opened due to compression or self elasticity, a first annular outer locking piece 4 is arranged and sleeved outside the single-section escape passage 2 in a clamp mode; the first annular lining part 3 is matched with the first annular outer locking part 4 inside, so that the capability of bearing vertical load at each position of the single-section escape passage 2 can be effectively improved, and the life and property safety is ensured.

As shown in fig. 2, the directions of the openings of the C-shaped bistable composite tubes 1 are not all the same. Specifically, due to the existence of the position of the C-shaped opening 11, if all the C-shaped openings 11 of the C-shaped bistable composite material pipe 1 are at the same position, the single-section escape passage 2 is open and cannot be closed, and dust, debris flow and the like may be caused to enter; it should be further appreciated that when at least two C-shaped openings 11 are located differently, the single-section escape route 2 as a whole is a closed cylinder with a greater load carrying capacity.

As shown in fig. 2, the directions of the openings of the C-shaped bistable composite tubes 1 are all different. Specifically, as with the above principle, when all the C-shaped ports 11 are located differently, the carrying capacity is stronger.

As shown in fig. 2, the opening directions of the C-shaped bistable composite tube 1 are uniformly distributed along the circumferential direction. Specifically, as in the above principle, when all the C-shaped ports 11 are uniformly circumferentially arranged, the distribution of the carrying capacity is most uniform and the carrying capacity is most strong.

As shown in fig. 4 and 5, a plurality of single-section escape passages 2 are connected end to end in sequence to form a multi-section escape passage. Specifically, in view of the requirements of portability and vertical load bearing, the length of the single-section escape passage 2 is necessarily limited, and when a user needs to span a longer dangerous zone, the multiple single-section escape passages 2 can be spliced front and back to form a longer multi-section escape passage.

As shown in fig. 3, 4 and 5, two ends of the single-section escape passage 2 are respectively provided with an annular concave connecting part 5 and an annular convex connecting part 6, and two adjacent single-section escape passages 2 are inserted into the annular concave connecting part 5 through the annular convex connecting parts 6 to be connected. Specifically, when two sections of single-section escape channels 2 are connected, the connecting piece is required to be stabilized; the simple scheme is that the annular lining piece and the annular outer locking piece are directly used for connection, but according to life practice, the connection is realized only by clamping, if the clamping distance is not long enough, the connection is still easy to break, so in the embodiment, the annular convex connecting part 6 of the previous single-section escape channel 2 is used for inserting the annular concave connecting part 5 of the subsequent escape channel, the connection strength can be effectively improved by not only clamping connection, but also friction connection.

As shown in fig. 3, 4 and 5, the single-section escape passage 2 is composed of at least three layers of equilong C-shaped bistable composite tubes 1, and the central C-shaped bistable composite tube 1 and the inner and outer C-shaped bistable composite tubes 1 are staggered in the axial direction to form an annular concave connecting part 5 and an annular convex connecting part 6. Specifically, because the single-section escape passage 2 in the device is formed by mutually sleeving the multi-layer C-shaped bistable composite material pipes 1, in the connection mode, in a more preferable mode, the end parts of the innermost layer and the outermost layer of the C-shaped bistable composite material pipes 1 are flush, and the end parts of one (or a plurality of) C-shaped bistable composite material pipes 1 between the innermost layer and the outermost layer of the C-shaped bistable composite material pipes are not flush (misplaced), so that the C-shaped bistable composite material pipes 1 inevitably form a convex connecting part and a concave connecting part at two ends of the single-section escape passage 2, and the device has more accurate structure and better connection effect.

As shown in fig. 4 and 5, the inner wall of the connecting position of each two sections of single-section escape channels 2 is abutted with a second annular lining member 7, the outer wall of the connecting position is sleeved with a second annular outer locking member 8, and the widths of the second annular lining member 7 and the second annular outer locking member 8 are respectively larger than those of the first annular lining member 3 and the first annular outer locking member 4. In particular, the second annular lining member 7 and the second annular outer locking member 8 for connection between the two single-section escape route 2 should have a wider width to increase the length of the grip, and to improve the connection effect, and when the annular concave connection portion 5 and the annular convex connection portion 6 are used for connection, the width of the second annular lining member 7 and the second annular outer locking member 8 should at least fully grip the connection portion.

As shown in fig. 6, the first annular lining member 3, the second annular lining member 7, the first annular outer locking member 4 and the second annular outer locking member 8 respectively comprise a plurality of detachable arc hoops 9, and the arc hoops 9 are connected by sequentially buckling 10 from head to tail. Specifically, in order to further improve the portability of the device, the annular lining piece and the annular outer locking piece are designed to be formed by connecting a plurality of arc hoops 9 end to end, when the escape passage is not used, the annular lining piece and the annular outer locking piece are disassembled and stored, the occupied space can be effectively reduced, and when the escape passage is used, the annular lining piece and the annular outer locking piece are combined into a circular ring shape by arc connection; the connection mode between the arc hoops 9 can use a buckle 10 mode, namely, the two ends of each annular hoop are respectively provided with a fixed part and a movable part of the buckle 10, and the buckle is buckled when connected end to end, so that the assembly speed is fast and efficient, and the assembly speed is effectively improved; the annular lining piece and the annular outer locking piece are made of metal materials such as steel materials, and have high strength and hardness.

In addition, after extensive practice, simulation calculation and finite element analysis processes, there is an optimal data range for the size of the C-shaped bistable composite tube 1, the distance between the first annular inner liner 3 and the first annular outer lock 4: the length of the single-section escape passage 2 is not less than 5000mm, the diameter is not less than 600mm, the single-section escape passage can be accommodated in a space of 800mm (width) X800mm (diameter) after being rolled, and every two first annular outer locking pieces 4 and the first annular inner lining piece 3 are spaced by 1250mm; the assembly time of the single-section escape passage 2 is not more than 15min, the disassembly time is not more than 10min, the normal service life is not less than 500 times of disassembly and assembly, and the pressure of soil (typical working condition) not less than 5 tons can be born.

The working principle of the device is as follows:

when the escape passage is not used, the C-shaped bistable composite material pipe 1 is unfolded to be a plane along the position of the C-shaped opening 11 and then rolled up to be a coil shape along the length direction, so that the space volume is reduced for storage and transportation; when an escape passage is needed, a user expands the roll shape into a plane and then rolls the plane along the width direction into a C-shaped bistable composite material pipe 1, and a plurality of C-shaped bistable composite material pipes 1 are sequentially coated from inside to outside to form a single-section escape passage 2 with multiple layers; the buckles 10 which are connected end to end with the arc hoops 9 are combined into the annular first annular outer locking piece 4 and the first annular inner lining piece 3, and are sleeved outside the single-section escape passage 2 or set in the single-section escape passage 2 to play a role in supporting and locking.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
