Limit hook device

Abstract

The invention discloses a limiting hook device which comprises a loop cover plate and a hook, wherein the hook comprises a hook body and a hook ejection plate; the hook ejection plate is arranged at one end of the hook body; a limiting part used for limiting the rotating angle of the hook is arranged on the hook ejection plate; the hook is mounted on the loop cover plate through a hook stop block; a cavity matched with the hook body is formed in the hook stop block; a cavity matched with the hook ejection plate is formed in the loop cover plate, so that the hook can freely rotate relative to the loop cover plate; and the loop cover plate is provided with an arc-shaped angular groove matched with the limiting part, so that the hook can be subjected to limited rotation relative to the loop cover plate. The limiting hook has the advantages of simple structure, capability of effectively limiting the rotating angle, low manufacturing cost, simple process and convenience for mounting and use.

Description

technical field [0001] The invention relates to a hook, in particular to a hook device with a position limiting function. Background technique [0002] The absorption circuit of the anesthesia machine is a combined gas circuit device connected between the anesthesia machine and the patient, and delivers anesthesia mixed gas to the patient. During the use of the anesthesia machine, due to the complexity of the anesthesia machine itself and the instrument lines and pipelines used in conjunction with it, if it is left to be placed randomly, it will bring a lot of inconvenience to the operator. In order to avoid the random placement of the lines and pipelines, it is necessary to The machine is equipped with a hook device for hanging lines and pipelines, which makes the operator's operating space tidy and convenient. [0003] Chinese patent document CN 201977511U discloses a "two-stage hook", such as Figure 8 As shown, the main body is the hook head 10, which is integrally conn...
