As the further of technique scheme improved and replenish, the utility model is taked following technical measures:
Described economical Inner door lock, location division have two, and described locating notch has more than three, come the other side's hyoplastron to carry out more reliable and stable location by two location divisions, and anti-wear performance and intensity are good, the long service life of lockset.
Described economical Inner door lock, the middle part of side's hyoplastron has a horizontal concrete chute, have a left side vertically chute and right vertically chute on the described slide plate, these two vertical chutes shift to install, vertical chute in a described left side and horizontal concrete chute all are enclosed within on the lead, the vertical chute in the described right side is enclosed within on the limited post, and described lead and limited post all are fixed on the lock body.By being used of lead and limited post and chute, make steady, the accurate positioning of moving of slide plate and square hyoplastron.
Described economical Inner door lock, tiltedly the inner of tongue forms a block, and an end that is installed in the plastics shift fork body on the lock body is conflicted on described block, is provided with a back-moving spring between the other end of plastics shift fork body and lock body, and spring is used for resetting of shift fork body.
Described economical Inner door lock, have a groove on the plastics shift fork body, this groove is built-in with a metal reinforced sheet, plastics shift fork body is played the effect of gaining in strength, the both sides of metal reinforced sheet form a plurality of barbs or hangnail, make reinforced sheet firm with combining of plastics shift fork body, the middle part of reinforced sheet has a through hole, and through hole is used for being connected with the inner of handle.
The structure that the utility model adopts location division and locating notch to be used under the elastic force effect of torsion spring, makes the positioning stablity of location division the other side's hyoplastron reliable, and the maintenance rate of lockset is low; Adopt the slide plate of two location divisions, its anti-wear performance and intensity are better, the longer service life of lockset; The embedded reinforced sheet of plastics shift fork body has guaranteed its anti-wear performance and intensity, is difficult for being damaged or damaging the long service life of lockset.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
