To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 to 5, an embodiment of the present disclosure discloses a cartridge with an anti-separation function, which includes a plurality of cartridges 10 and a sleeve body 20.

The cylinder 10 can be obtained by cutting a metal pipe with a larger major diameter, so that the length-diameter ratio of the cylinder 10 is as small as possible, the multiple cylinders 10 are sequentially butted to form a long cylinder adapted to the depth of the deep hole 100, two adjacent cylinders 10 are butted by means of the sleeve body 20, specifically, internal threads 21 are respectively arranged at two ends of the sleeve body 20, external threads 11 are respectively arranged at two ends of the cylinder 10, and the ends of the cylinders 10 at two sides of the sleeve body 20 are detachably connected by means of the matching of the external threads 11 and the internal threads 21 by extending into the end of the sleeve body 20. The utility model discloses in, through-hole 22 has still been seted up at the middle part of the cover body 20, and the radial cover body 20 that runs through of this through-hole 22 wears to be equipped with linear elastomer 30 on this through-hole 22, for example, wears to establish the wire rope that has the ability of resetting after buckling, makes the length of this elastomer 30 be greater than the great person of the radial dimension in the cover body 20 and the barrel 10, and then makes the radial barrel 10 and the cover body 20 that stretches out in both ends of elastomer 30.

It is known to provide cartridges containing explosives, said cartridges being provided in such a way that:

one of the barrels 10 is used as the most front barrel 10, the barrel 10 is filled with explosive firstly, after the filling is finished, the sleeve body 20 is arranged at the tail end of the barrel 10, the second barrel 10 is arranged at the tail end of the barrel 10, then the explosive is filled into the second barrel 10, and the filling of the explosive is finished in the same way.

It should be noted that: the elastic body 30 may pass through the through hole 22 before or after the jacket 20 is mounted on the cylinder 10.

After the medicine cartridge which conforms to the depth of the deep hole 100 is assembled, the medicine cartridge extends into the deep hole 100, the elastic body 30 is forced to bend by the hole wall of the deep hole 100, however, the elastic body 30 has a resetting trend, so that the elastic body 30 has a large counter force to the hole wall, the counter force enables a large friction force to be formed between the elastic body 30 and the hole wall, and the medicine cartridge can be effectively prevented from being pulled out of the deep hole 100 under the action of gravity.

The advantages of the above embodiment are:

1. the cartridge is formed by detachably abutting a plurality of cartridges 10 having relatively small major diameters, and further, the cartridges 10 can be filled with explosive conveniently.

2. The cartridge can be effectively prevented from being removed from the deep hole 100 by adding the sleeve body 20 and the elastic body 30.

In a preferred embodiment of the present invention, a rubber rod 31 is disposed at the end of the elastic body 30, and the rubber rod 31 can form a larger friction force with the hole wall of the deep hole 100, thereby more effectively preventing the cartridge from being removed from the deep hole 100.
