Abstract
The utility model relates to a fire-resistant lock, which includes a lock body formed by buckling an upper cover plate and a lower cover plate together, wherein an upper locking plate is arranged at the top of the lock body; a lower locking plate is arranged at the bottom of the lock body; a lock body panel is arranged at the left end of the lock body; a dead bolt component and a latch bolt component are arranged on the lock body panel from top down; a cam wheel is arranged inside the lock body and above the dead bolt component and connected with the dead bolt component through a cam wheel torsion spring; the guide plate is arranged under the dead bolt component; a lock plate driving device is arranged on the guide plate and close to the left end of the guide plate; a guide plate flat spring is arranged on the right side of the guide plate; and a shift fork is arranged below the guide plate and connected with the right end of the guide plate through a shift fork bottom disc. The fire-resistant lock has the benefits as follows: the structure is novel, particularly the structure including top and bottom poles and top and bottom heads is adopted to realize multi-point locking; and upper and lower corners of a door body can not be deformed by high temperature after long-time burning, thereby achieving the effect of preventing fire-escaping and the purpose of resisting fire truly.
Description
Technical field
The utility model relates to a kind of Fire-proof lock.
Background technology
Continuous development along with technology, the fire-proof function of labeled door also obtains constantly perfect, wherein topmost is exactly to obtain the continuous development support of Fire-proof lock structure, but Fire-proof lock structure in the market all has only and utilizes oblique tongue and square tongue with the labeled door locking, under the situation of overlong time of catching fire, labeled door two angles is up and down located easily because of temperature distortion, thereby causes the string fire, loses the fireproof function.
The utility model content
The purpose of this utility model provides a kind of Fire-proof lock, all have only and utilize oblique tongue and square tongue to overcome in the market Fire-proof lock the labeled door locking, under the situation of overlong time of catching fire, labeled door up and down place, two angles easily because of temperature distortion, thereby cause the string fire, lose the deficiency of fireproof function.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of Fire-proof lock, comprise by upper cover plate and lower cover and fasten the lock body that forms mutually, the top of described lock body is provided with upper lock plate, the bottom of lock body is provided with lower locking plate, the left end of described lock body is provided with lock panel, the side's of being provided with tongue assembly and tiltedly tongue assembly successively from top to bottom on the lock panel, the top of the side of being positioned at, described lock body inside tongue assembly is provided with cam, cam is connected with square tongue assembly by the cam torsion spring, be provided with guide strip under described side's tongue assembly, be provided with the jam plate drive unit near the left end place on the guide strip, the jam plate drive unit comprises connecting rod and lower link, last connecting rod is connected with upper lock plate with lower locking plate respectively by steel wire with lower link, the right side of guide strip is provided with the guide strip flat spring, the left end of guide strip flat spring is resisted against in the groove of guide strip, and the below of described guide strip is provided with shift fork, and shift fork is connected with the right-hand member of described guide strip by the shift fork egative film.
The beneficial effects of the utility model are: novel structure, adopt the structure of the universe rod and the top and bottom margins of a page, can realize the multiple spot locking simultaneously, door body when catching fire overlong time up and down two jiaos high temperature deformation can not take place, thereby reach do not go here and there the fire effect, reach real fireproof purpose.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of Fire-proof lock of the utility model embodiment;
