The above-mentioned letter lock of sliding door and window one, after dialing up sliding part and locking, due to lacking position limiting structure on a letter lock, In door and window push-and-pull, sliding part can fall naturally in the case of user is unwitting sometimes, and lock point also falls therewith, causes One letter lock opens by mistake, and influences to use safely.
Utility model content
The purpose of utility model is to overcome above-mentioned the deficiencies in the prior art part, there is provided an a kind of letter lock of sliding door and window, Opening by mistake for lock is avoided that, securely and reliably, moreover, using more easily laborsaving.
In order to solve the above technical problems, the technical solution of the utility model is:A kind of one letter lock of sliding door and window is provided, wrapped Include the lock of in-line, the middle part of lock panel, provided with the perforation that upper and lower ends are arc, the back of lock, provided with along lock The chute of extension, sliding part is plugged with chute, the upper end of sliding part is upper struck side, and the back of upper struck side is connected with lock Fork, the bottom of sliding part be lower struck side, the surface of lower struck side, and provided with raised crescent shape limited block, limited block can be with The lower end of perforation is offseted, and the radian of the two is mutually matched;
Surface top of upper struck side or so, the aperture provided with two built-in springs, it is hoodle on each spring, this Two hoodles are tight against the back side of lock panel;
Lower backside of upper struck side or so, the aperture also provided with two built-in springs, it is hoodle on each spring, This two hoodles are tight against the bottom land of chute;
The lower backside of lower struck side, provided with torque spring, bottom land of the torque spring tight against chute.
One letter lock of sliding door and window as described above, lower struck side is formed in one with limited block.
One letter lock of above-mentioned sliding door and window, due to can pushed away by the mutual cooperation of torque spring, limited block and perforation etc. After sliding door and window is locked, position-limiting action can be played to sliding part, so as to correspondingly play position-limiting action to lock point, be avoided that lock Open by mistake, securely and reliably, moreover, the upper struck side of sliding part is provided with four springs, the back side by four hoodles tight against lock panel Or the bottom land of chute so that sliding part is moved up and down with rolling condition, and the use locked and unlocked is more easily laborsaving.
