Gate device capable of being automatically opened and closed

Abstract

The invention discloses a gate device capable of being automatically opened and closed. The gate device achieves automatic opening and closing functions by virtue of an object touch and separation process; the gate device is formed by connecting a gate rotary plate component with a gate mounting dead plate by virtue of a rotating shaft and a torsion spring; a primary driving wheel component is fixedly arranged on the gate rotary plate by virtue of a nut, and a primary driving wheel spacing plate is fixedly arranged on the gate rotary plate (2) by virtue of a nut; when the object touches the primary driving wheel, the whole device is driven to rotate downward; when the device rotates to the secondary driving wheel and touches the object, the primary driving wheel is separated from the surface of the object, the secondary driving wheel drives the device to continuously rotate downward; when the primary driving wheel component touches a plate wall, torsion of the torsion spring can be overcome, and autorotation and shrinkage can be realized, so that the required minimum space is realized. The gate device is simple in structure and smart in concept, and can be used for effectively utilizing the existing space and smartly utilizing the advancing and retreating of the object to control the opening and closing of a gate.

Description

technical field [0001] The invention relates to a device for opening and closing a gate, in particular to a device for automatically opening and closing a gate. Background technique [0002] At present, most of the gate devices on the market are electric gates, and purely mechanical gates also have certain requirements on the opening angle. The opening process of existing purely mechanical gate devices needs to be opened from the front. Finally, the occupied space needs to be very large, which is not conducive to widespread promotion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic opening and closing gate device that reduces the height of the gate and reduces the required space for gate opening. [0004] In order to solve the above problems, the automatic opening and closing gate device provided by the present invention includes a gate installation fixed plate and a gate rotating plate. The rear en...
