Description

Locking mechanism and lifting screen Technical Field The utility model relates to the field of furniture, in particular to a locking mechanism and a lifting screen. Background In modern office scenes, the desktop screen is used as a common device for desktop space separation, privacy protection and vision buffering, the practicability and convenience of the height adjusting function are very important, however, the traditional desktop screen has functional defects of height adjustment, and diversified office requirements are difficult to meet. The prior desk-top screen adopts a fixed height design, can not be dynamically adjusted according to the heights of users, office scenes or cooperation demands, the user with higher heights can possibly interfere the desktop activities by the sight of other people due to the too low screen, privacy protection is insufficient, the user with shorter heights can possibly form visual depression due to the too high screen to influence natural communication with colleagues, when temporary cooperation or group discussion is needed, the fixed-height screen can not be quickly reduced to create open atmosphere, and when the user is focused on offices, the user can not be lifted to enhance privacy, so that the use experience of 'one-cut' is caused. The traditional lifting scheme is mostly dependent on mechanical structures such as a gear rack, a screw nut and the like, and often depends on self-locking capability in the mechanism, so that the stay height of the screen is influenced under the condition of sliding down and sinking due to gravity or load, and the use experience is low, so that an applicable locking mechanism is needed to lock the structure of the screen. Disclosure of Invention In order to solve the technical problems, the utility model provides a locking mechanism which comprises a rotating member, a base, a switch and a locking member, wherein the base is used as a main body to support the rotating member, the rotating member is arranged in the base and can rotate, the switch is arranged on the base, the locking member is in floating arrangement and is abutted with the switch, a locking part of the locking member can be selectively locked with the rotating member, when the switch rotates upwards on the base, the locking member is lifted to unlock the rotating member, the switch rotates downwards, the locking member falls down to realize the locking of the locking member, the locking and unlocking can be controlled through simple switch rotation operation, the convenience of use is greatly improved, the unique floating abutting design of the locking member can effectively prevent the falling caused by gravity to ensure the stability of equipment, and meanwhile, the mechanism uses the base as a core, has a compact structure, does not need complex driving parts, the cost is reduced, and the reliability of products is improved. And then provides a lifting screen, including main part, crossbeam and above-mentioned locking mechanical system, the main part goes up and down to set up on the crossbeam, and the rotation of rotating the piece links with the lift of main part, and locking mechanical system locks the rotating the piece and is the locking to the main part. The technical scheme of the utility model is realized as follows: A locking mechanism comprises a rotating member, a base, a switch and a locking member, wherein the base is configured as a main body support of the locking mechanism, the rotating member is rotatably arranged in the base, the switch is rotatably arranged on the base, the locking member is arranged on the base in a floating mode and is abutted to the switch, the locking member comprises a locking part which is slidably arranged in the base and is selectively locked and matched with the rotating member, when the switch rotates upwards on the base, the locking member is lifted and unlocked with the rotating member, and when the switch rotates downwards on the base, the locking member falls down and is locked with the rotating member. The locking and unlocking of the locking piece and the rotating piece are controlled through the rotation of the switch on the base, the operation mode is simple and visual, compared with the traditional complex locking operation, the switching of the lifting and locking of the screen can be realized rapidly by only rotating the switch easily by a user, and the use convenience is greatly improved; in addition, the locking mechanism takes the base as the main body for supporting, the structure is compact and simple, complicated hydraulic, gas rod or large motor and other parts are not needed, the production cost is reduced, the probability of occurrence of faults is reduced, and the reliability of products is improved. Preferably, the end of the rotating member is located in the base and is provided with a locked member, and the locked member is rotationally set in synchronization with the rotating member.
