[0013] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. EMBODIMENT

[0014] See Figs. 1-2 As shown in the figure, a novel gas spring outer tube fixing structure, comprising a gas spring body 1, the middle part of the end face of the gas spring body is provided with an outer tube fixing hole 2, the inner wall of the outer tube fixing hole is provided with an internal thread 3; its gas spring body is the conventional structure of the prior art, so it is not recorded in detail, at the same time, the entering end of the outer tube fixing hole is provided in a horn shape. Through the above structure, the plug-in connection operation of the outer tube is facilitated.

[0015] At the same time, in the embodiment, the inner end diameter of the outer tube fixing hole is smaller than the outer end diameter of the outer tube fixing hole. Through the above structure, the stability and smooth reliability of the outer tube 4 connection can be improved.

[0016] At the same time, in the actual application process, the outer end hole diameter of the outer tube fixing hole is 1 / 3-1 / 2 of the end face diameter of the gas spring body.

[0017] The utility model has the positive effect: the structure of the utility model is reasonable, it adopts an outer tube fixing hole, which is conducive to reducing the processing difficulty, and the inner wall of the outer tube fixing hole has an internal thread, when the outer tube is connected, the outer tube can be positioned through the internal thread, the stability and reliability of assembly are improved, the difficulty of outer tube assembly is also reduced, and the applicability is strong.

[0018] The standard parts used in the embodiment can be directly purchased from the market, and the non-standard structure parts according to the description recorded in the specification can also be directly processed according to the existing technical knowledge without doubt, at the same time, the connection mode of each part adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional type in the prior art, so specific description is not made here.

[0019] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation modes. The obvious changes or variations extended from the essential spirit of the present application still belong to the protection scope of the present application.
