Stall protection device for preventing smart home door from pinching hands

Abstract

The invention relates to the technical field of smart home, and discloses a stall protection device for preventing a smart home door from pinching hands. The stall protection device comprises a firstshell, the interior of the first shell is fixedly connected with a fluid shell, the interior of the fluid shell is movably connected with a movable block, and the exterior of the movable block is fixedly connected with a telescopic spring. Under the interaction of all the structures of the device, the device can automatically trigger the function of preventing hands from being pinched when the self-suction anti-theft door is under the action of strong force such as external strong wind so that the accident of pinching the hands can be effectively avoided, the safety of the intelligent anti-theft door can be better, and when the self-suction anti-theft door is subjected to the external strong action, the device can also enable a friction block to rub with the self-suction door, so that under the dual protection of the sliding friction force and the electrorheological fluid, the effect of preventing the self-suction door from pinching hands is better, and meanwhile, the service life of the intelligent door is also prolonged.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a stall protection device for preventing smart home doors from pinching and injuring hands. Background technique [0002] With the progress and development of society, smart home has been gradually integrated into people's daily life. Among them, the self-priming anti-theft door is a kind of smart home door, but the current self-priming anti-theft door still has some problems in practical application. Many problems, for example, the existing self-priming door does not have a device to prevent the hands from being pinched, so that when the self-priming anti-theft door is subjected to external forces such as strong winds, the self-priming door will be closed quickly, thereby There may be accidents where anti-theft doors pinch people's hands, which will threaten people's safety, and at present, some smart anti-theft doors that prevent people from being pinched are less effective,...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stall protection device to prevent the smart home door from pinching human hands, which can automatically perform manual anti-pinching operations under the action of external forces such as strong winds, and can better increase the number of movable doors. The advantage of service life solves the problem that the existing self-priming doors do not have an anti-pinching device, which will mak
