Description

Novel universal lock for screen window switch Technical Field The utility model relates to the technical field of screen window locks, in particular to a novel lock for screen window switches. Background In building door and window field, the screen window tool to lock is as realizing the core component that the screen window was opened and close and was locked, and its structural design and mounting means directly influence use experience and engineering efficiency. The traditional screen window lockset is generally designed in a left-right split mode, namely, the left-opening screen window and the right-opening screen window are required to be provided with locksets with different specifications, and the design causes the following technical problems: The manufacturer needs to produce left and right locks respectively, the distributor needs to store double sets of stock, increase the development cost of the mould, the occupation of the storage space and the risk of diapause; The installation efficiency is low, an installer needs to judge the opening direction of the screen window in advance, distinguish the left lock from the right lock, then carry out left and right measuring tape, the working content is complex, the traditional lock needs to be debugged in a complex way, and the single installation time is long; Therefore, how to provide a novel lock for a screen window switch which is universal in the left and right directions and can be assembled and matched without distinguishing the left and right directions is a problem to be solved by the person skilled in the art. Disclosure of utility model In view of this, the utility model provides a novel lockset which is universal to the left and right of a screen window switch. In order to achieve the above purpose, the utility model provides the following technical scheme, A novel lock for a screen window switch in a left-right general way comprises a lock shell, a transmission bar and a limiting mechanism, wherein mounting holes for fixed mounting are symmetrically formed in two ends of the top of the lock shell, and limiting holes are formed in the front face of the lock shell at intervals along the length direction, the transmission bar is slidably embedded in the lock shell, a lock cylinder hole is formed in the top of the transmission bar, meanwhile, limiting mechanism mounting holes are respectively formed in two ends of the transmission bar, a shifting fork is fixedly connected with the transmission bar through a shifting fork fixing hole, a lock cylinder penetrates through the lock cylinder hole of the transmission bar and is fixedly connected with the shifting fork, and the limiting mechanism is mounted in the limiting mechanism mounting hole of the transmission bar and used for achieving position positioning of the transmission bar. Preferably, two groups of limiting holes are symmetrically distributed at two ends of the side wall of the sliding groove on the inner side of the lock shell, and specifically, the two groups of symmetrically distributed limiting holes are uniformly distributed at intervals respectively.
