Description
Technical field
The present invention relates to a kind of door lock, especially a kind of for regulating and locking without cold bridge spanner degree of tightness on air-conditioning fan box access door.
Background technology
At present, be all provided with the convenient access door that internal unit is overhauled in general device casing, access door is provided with door lock.Existing access door door lock mostly adopts the comparatively simple rotary door lock of mode of operation, it generally comprises handle, rotating shaft, rotation tongue, when installation, handle is positioned at outside access door, rotation tongue is positioned at access door, by rotating shaft connecting handle and rotation tongue, thereby in the time of turning handle, rotation tongue rotates in the lump, realizes and unblanks and close latching operation.Although this class door lock is easy for operation, aspect safety and sealing, be comparatively short of.In order to improve safety and sealing, conventionally adopt mechanical lock is set on handle, sealing ring is set in handle set and realizes, but structure to be installed comparatively complexity, after long-time use, lock body is easily loosening, thereby causes sealing effectiveness not good enough.For this reason, need existing door lock to be improved.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide to this area a kind of and regulate lock without cold bridge spanner degree of tightness, make it solve existing similar Door lock structure comparatively complicated, the not good enough technical problem of sealing performance after long-time use.Its objective is and be achieved through the following technical solutions.
This regulates lock to comprise handle, lock body, handle set, rotating shaft, rotation tongue without cold bridge spanner degree of tightness, and lock body comprises lock core and lock, and lock core rotation is positioned in lock, and lock and handle are a disjunctor, and lock rotation is positioned in handle set.Its structural feature is that the end of described lock core is provided with the protruding axle that is eccentric setting with respect to lock core axle center, and described lock side face is provided with the pin-and-hole that radially runs through setting along lock, and the lock pin of slip is set in pin-and-hole, and lock pin is provided with the breach that coordinates interlock with described protruding axle; When lock core does not rotate, described pin-and-hole is stretched out in described lock pin one end, and coordinates with the lockhole being provided with in described handle set; In described lock, be divided into upper and lower two chambers, described lock core, lock pin are installed by upper chamber, the lower chambers described rotating shaft that is in transmission connection, and rotating shaft is fixedly connected with rotation tongue through the axle sleeve of described handle set; The described lock side face that is positioned at described pin-and-hole below is provided with annular seal groove, and seal groove is embedded in sealing ring, by sealing circle to sealing between lock and handle set.By above-mentioned lock body is set, and fitted seal circle, can the better sealing that must realize between lock body and handle set, and lock body unlocking structure is comparatively simple, reliable, after long-time use, is difficult for becoming flexible, getting stuck, and operates comparatively laborsaving.
Described lock end is provided with convex tendon, is provided with the arc-shaped limit groove being slidably matched with convex tendon in described handle set.Thereby coordinate with arc-shaped limit groove and realize the rotation-limited of lock in handle set by convex tendon.
In described handle set, die casting has wear-resisting lock tube, described lockhole is arranged at wear-resisting lock tube side face, described lock side face is provided with annular ball water jacket, the inner peripheral surface of described wear-resisting lock tube is provided with the ball inside groove corresponding with described ball water jacket, described handle set and wear-resisting lock tube are provided with the ball hole communicating with described ball inside groove, in the ball grooves forming to described ball inside groove and ball water jacket by this ball hole, inject ball, lock by alignment pin and ball hole, ball is limited in ball grooves.Adopt the wear-resisting lock tube of rheo-die-casting in handle set, thereby prevent lock body, the wearing and tearing of ball to handle set.Realize the locating rotation between lock and wear-resisting lock tube by ball, not only location is comparatively reliable, and rotation is comparatively flexible, longer service life.
Described lock pin cross section is polygon, and described pin-and-hole mates with lock pin.By this kind of structure, when lock pin slides in pin-and-hole, can there is not rotation, thereby guarantee that the protruding axle of lock core end and lock pin breach reliably link.
Described lock core side face is provided with annular positioning groove, between described lock and lock core locating slot, locates by pin; Described lock core upper end side face is provided with limited block, and corresponding described core print seat end face is provided with the stopper slot being slidably matched with limited block.By this kind of structure, realize the rotation-limited between lock core and lock.
This degree of tightness regulates lock also to comprise transfer bar mechanism, transfer bar mechanism comprises that being counterrotating outer cunning leads with interior cunning and lead, interior cunning is led and is placed in outer cunning leads, outer cunning is led and described lock interlock, and interior cunning is led and is positioned in described handle set, and outer cunning is led side face and is provided with spiral slide opening, interior cunning is led side face and is provided with L-type slide opening, slide and be placed in interior cunning leads in described rotating shaft one end, and the vertical axostylus axostyle that connects of rotating shaft, and axostylus axostyle slides and is placed in described spiral slide opening and L-type slide opening.By transfer bar mechanism is set, in the time that rotating shaft driven rotary tongue rotates, by transfer bar mechanism, rotating shaft is stretched out to handle set one segment length, thereby make the adjusting bolt of rotating tongue depart from locking face corresponding to access door, not only flexible operation, the wearing and tearing while effectively having avoided existing rotation tongue to rotate and between access door, have extended rotation tongue application life, and between rotation tongue when locking locking face corresponding with access door, there is the effect of a compression, thereby improved the reliability that access door is locked.
Between one end that described rotating shaft is led in described interior cunning and described lock lower chambers, be provided with the power assistant spring of compression.By this power assistant spring, above-mentioned transfer bar mechanism is promoted to rotating shaft and play power-assisted effect, make transfer bar mechanism promote rotating shaft comparatively flexible.
Described rotating shaft is through the axle sleeve socket sealing mat of described handle set, and first locking nut that is threaded, and described sealing mat seals the gap between axle sleeve and the rotating shaft of described handle set; Described rotating shaft connects the second locking nut through described rotation tongue one end after connecting the first locking nut; The described rotation tongue other end adjusting bolt that is threaded, the adjusting bolt adjusting nut that is threaded.Connect adjusting bolt and adjusting nut by rotation tongue, thus the convenient coupling mechanism force regulating between rotation tongue and access door.
The bolt cap of described adjusting bolt is software part, or the bolt cap sleeve of adjusting bolt connects software cover.By this kind of structure, be conducive to reduce adjusting bolt bolt cap to the wearing and tearing between locking face
In described adjusting bolt, between described bolt cap and rotation tongue, be socketed dustproof corrugated flexible hose.Play dustproof effect by this dustproof corrugated flexible hose.
Structure of the present invention is comparatively simple, and operation is used more for convenience, and sealing cold-prevention bridge is effective, long service life, the door lock that is suitable as all kinds of access doors uses, especially uses as the door lock of cold-prevention bridge air-conditioning fan box access door, or the architecture advances of like product.
