Problems solved by technology

However, the size of the pull screen is mostly used in the range of 70 to 84 inches. It lacks stretching and adjustment performance and people's demand for dual-screen display. People's operating experience and functional requirements are getting higher and higher. Not only good quality, but also Good experience, so it is necessary to provide a projection screen that is easy to operate, has high stability and is not easy to fail

Abstract

The invention discloses a hydraulic pedal type telescopic ground-pulled double-screen projection screen. The hydraulic pedal type telescopic ground-pulled double-screen projection screen comprises a screen module, a storage module, a lifting module and a support module; the screen module is used for receiving light transmitted by a projector, and displaying the image at the same time; the storagemodule is connected with the screen module, and used for rolling the screen module and storing the screen module in a storage box; the storage module is connected with the lifting module; a hydraulicstructure is arranged below the lifting module; a control pressure rod below the lifting module is pressed, so that the storage module can be lifted and adjusted; the support module is connected withthe lifting module, arranged at the bottom of the lifting module, and used for fixing the lifting module; the support module can be unfolded and folded by pressing a folding and unfolding fixing button arranged on the support module; due to the lifting module with the hydraulic rod, the height of the screen can be adjusted simply and conveniently; and thus, the projection screen is simple in structure and convenient to carry.

Description

technical field [0001] The invention relates to the field of projection screens, in particular to a ground-pull double-screen projection screen that can be retracted by hydraulic pedals. Background technique [0002] At present, the commonly used projection screens are mainly divided into: manual self-locking screens, electric screens, bracket screens, floor screens, and picture frame screens. Manual self-locking screens are very popular among consumers for their favorable price and easy installation. The disadvantage is that during long-term use, especially for screens over 80 inches, it is best not to choose manual screens, because the central pull-down force and other reasons will appear " V" type corrugation affects the flatness of the screen. For example, a projector screen disclosed by the publication number CN206725949U, when in use, the thin plate is unfolded to form a whole board, and after the reel is hung or fixed to the wall, the screen is pulled out from the ree...
