Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and in particular to a land-based rescue missile. Background Technology

[0002] Land-based rescue grenades are a crucial component of rescue throwers, primarily used in land-based scenarios such as mountain rescues and high-rise building fires. They precisely deliver rescue supplies or firefighters over long distances, overcoming access difficulties caused by terrain or fire intensity. Existing land-based rescue grenades have a problem: the rescue rope inside the rope tube passes directly through a through-hole at one end. During use, high-pressure gas from the thrower can enter the rope tube through this through-hole, causing it to burst and become damaged. Furthermore, the transition tube is glued to the rope tube and the central tube, making it prone to detachment, which is a significant drawback. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems by providing a land-based rescue missile.

[0004] The technical solution of this utility model is as follows: A land-based rescue missile includes a tail cap, a rope tube, a middle tube, a transition tube, a front tube, a guide rope, a rescue rope, and a wing tube. The tail cap is detachably mounted on one end of the rope tube. One end of the transition tube is located between one end of the rope tube and one end of the middle tube, and the transition tube is connected to the front tube. One end of the guide rope is located on one end of the front tube, and the other end is connected to one end of the rescue rope. One end of the wing tube is mounted on the rope tube, and the other end is mounted on the middle tube. The tail cap has an oblique hole and a clearance groove, and the oblique hole and the clearance groove are connected. The other end of the rescue rope passes through the oblique hole.

[0005] Preferably, the tail cap has an upwardly extending annular protrusion.

[0006] Preferably, the rope tube is provided with an annular connecting pad; it also includes a plurality of locking members, which are used to connect the connecting pad, the middle tube and the transition tube.

[0007] Preferably, the connecting pad has several threaded holes, the transition tube has an annular connecting plate, the middle tube and the connecting plate both have several through holes, and the locking element is a bolt.

[0008] Preferably, the central tube is a carbon fiber central tube.

[0009] The beneficial effects of this utility model are: by providing oblique holes on the tail cap, damage to the rope tube can be avoided, and the utilization rate of the kinetic energy of the high-pressure gas can be improved, thereby increasing the range of the rescue missile.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1 to 3A land-based rescue missile includes a tail cap 10, a rope tube 2, a middle tube 3, a transition tube 4, a front tube 5, a guide rope 6, a rescue rope 7, and a wing tube 8. The tail cap 10 is detachably mounted on one end of the rope tube 2. One end of the transition tube 4 is located between one end of the rope tube 2 and one end of the middle tube 3, and the transition tube 4 is connected to the front tube 5. One end of the guide rope 6 is located on one end of the front tube 5, and the other end is connected to one end of the rescue rope 7. One end of the wing tube 8 is mounted on the rope tube 2, and the other end is mounted on the middle tube 3. The tail cap 10 has an oblique hole 101 and a clearance groove 102, which are connected. The other end of the rescue rope 7 passes through the oblique hole 101. In this invention, the right end of the front tube 5 has a countersunk hole, and the left end of the transition tube 4 has a small hole. One end of the guide rope 6 is knotted, and the other end passes through the countersunk hole and the small hole at the left end of the transition tube 4 to connect with one end of the rescue rope 7 inside the rope tube 2, and is knotted at the connection point. After the rescue rope 7 is inserted into the rope tube 2, a certain length is left at the other end, and this remaining length is knotted. The other end of the rescue rope 7 can then pass through the oblique hole 101. In use, the rescue projectile is placed into the launching tube of the launcher, and the outer wall of the tail cap 10 is flush with the launching tube. The inner wall of the tube is fitted tightly. Due to the setting of the oblique hole 101, the air pressure in the launcher will not flow into the rope tube 2, preventing the rope tube 2 from being blown open. At the same time, the rescue rope 7 extends from the avoidance groove 102 through the launch tube and connects to the launcher, avoiding gaps between the outer wall of the tail cover 10 and the inner wall of the launch tube. When the launcher is working, the land-based rescue missile is launched from inside the launch tube. The knotted part of the remaining length of the rescue rope 7 pulls the tail cover 10 out of the rope tube 2 during the flight of the rescue missile, and the rescue rope 7 inside the rope tube 2 is released. Specifically, the transition tube 4 and the front tube 5 are open at one end and have a cavity in the middle.

[0016] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0017] In this embodiment, the tail cap 10 is provided with an upwardly extending annular protrusion 103. The annular protrusion 103 is made of nylon material to make it elastic. The tail cap 10 is fixed to the rope tube 2 by interference fit with the inner wall of the rope tube 2 through the annular protrusion 103. When in use, the knot of the rescue rope 7 will pull the tail cap 10 out of the rope tube 2 during the flight of the land rescue missile, so that the rescue rope 7 can be released.

[0018] In this embodiment, the rope tube 2 is provided with an annular connecting pad 201; it also includes a plurality of locking members 9, which are used to connect the connecting pad 201, the middle tube 3 and the transition tube 4, and the transition tube 4, the middle tube 3 and the rope tube 2 are connected together by the locking members 9.

[0019] In this embodiment, the connecting pad 201 is provided with a plurality of threaded holes 2011, the transition tube 4 is provided with an annular connecting plate 401, the middle tube 3 and the connecting plate 401 are provided with a plurality of through holes, the locking member 9 is a bolt, the locking member 9 passes through the through holes on the connecting plate 401 and the middle tube 3 and connects with the threaded holes 2011, thereby connecting the transition tube 4, the middle tube 3 and the rope tube 2 together.

[0020] In this embodiment, the central tube 3 is a carbon fiber central tube. The carbon fiber central tube is lightweight and has high strength, making the land-based rescue missile less prone to damage. In addition, the carbon fiber central tube is lightweight, which can reduce the weight of the land-based rescue missile.
