[0015] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, if the terms "first", "second", and "third" are used, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] As shown in the figure, a pen-type injection needle storage cylinder includes a shell 1, an injection needle, a long rod 2 and a telescopic unit 3. The shell 1 is a hollow cylindrical structure. A round hole 11 is provided at the upper end of the shell 1. The long rod 2 matches the round hole 11. A cap 12 is threadedly connected to the bottom of the shell 1. The telescopic unit 3 is arranged at the bottom of the shell 1, wherein the telescopic unit 3 includes a limit rod 31, a telescopic spring 32 and a fixed recess 33. The fixed recess 33 is fixedly connected to the shell 1. A notch is provided on one side of the shell 1. The limit rod 31 extends into the notch. One end of the telescopic spring 32 is fixedly connected to the notch, and the other end is fixedly connected to the fixed recess 33. The bottom of the limit rod 31 is inclined. The injection needle includes a needle body and a sleeve shell. See attached Figure 1 The housing includes an outer sleeve, a gasket 4 and a sealing sheet, wherein the outer sleeve is a cylindrical structure with an opening at the lower end, the gasket 4 is arranged at the bottom of the outer sleeve, and the sealing sheet is sealed with the gasket 4, wherein the sealing sheet seals the needle body inside the outer sleeve, and when in use, only the sealing sheet needs to be torn off to expose the needle body.

[0019] As a further improvement of the present invention, the injection needle is placed inside the housing 1 .

[0020] As a further improvement of the utility model, the number of injection needles is 5, and the injection needles are arranged in sequence from top to bottom.

[0021] As a further improvement of the present invention, a fixing sleeve 13 is provided on one side of the housing 1 , and the fixing sleeve 13 cooperates with the long rod 2 to achieve the fixation and use of the long rod 2 .

[0022] As a further improvement of the present invention, the limiting rod 31 cooperates with the gasket 4, and the gasket 4 and the outer sleeve are made of medical plastic material, wherein the gasket 4 cooperates with the inclined end of the limiting rod 31. When the long rod 2 presses the outer sleeve downward, the gasket 4 contacts the limiting rod 31, and the telescopic spring 32 is forced to move upward, and the gasket 4 moves out from the limiting rod 31. The diameter of the gasket 4 is larger than the diameter of the outer sleeve. After the gasket 4 moves out, the limiting rod 31 rebounds under the action of the telescopic spring 32, thereby limiting the removal of the next injection needle.

[0023] As another embodiment of the present utility model, the bottom of the limiting rod 31 is an inverted triangle structure, which is convenient for adding or removing the injection needle into the housing 1.

[0024] The utility model has a reasonable structure, wherein the shell 1 is used to store multiple injection needles, a round hole 11 is provided at the upper end of the shell 1, and the round hole 11 cooperates with the long rod 2. After the long rod 2 is pressed down, the injection needle moves to the bottom of the shell 1, and the telescopic unit 3 can well limit the injection needle from moving downward. When in use, when the long rod 2 presses the outer sleeve downward, the washer 4 contacts the limit rod 31, and the telescopic spring 32 is forced to move upward, and the washer 4 moves out from the limit rod 31, wherein the diameter of the washer 4 is larger than the diameter of the outer sleeve. After the washer 4 moves out, the limit rod 31 rebounds under the action of the telescopic spring 32, which limits the next injection needle from moving out, making single-time taking more reasonable, reducing the risk of the injection needle being exposed to the outside, and improving safety.

[0025] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
