Problems solved by technology

However, spring steel is expensive and the manufacturing process is cumbersome, and plastic materials cannot adapt to the changing climate environment, especially when used in low temperature areas, it is very easy to become brittle and break
Moreover, the structure that the oblique bolt is divided into two also increases the manufacturing cost and the management cost

Embodiment 1

[0039] The first embodiment mainly relates to the technical solution that the locking arm 52 can not only move axially but also rotate radially so as to reversibly lock the oblique bolt 3 .

[0040] Such as figure 1 and figure 2 As shown, a door lock includes a lock body, and the lock body includes a housing 1, and the housing 1 has six sidewalls up and down, left and right, and front and back, and the six sidewalls form an accommodation chamber. in figure 1 An opening 10 is provided on the upper side wall body 1a indicated in figure 1 and figure 2 The front and rear side walls (1d, 1c) of the housing 1 are shown. The housing 1 is provided with a driving mechanism linked with the door handle, an oblique bolt 3 capable of locking the door leaf, a locking arm 52 for locking the oblique bolt 3 and the positioning column 5 . The oblique lock tongue 3 can slide out in the opening 10 to close the door leaf, and when retracted into the housing 1 , it is convenient to open the ...

Embodiment 2

[0071] The second embodiment mainly relates to the technical solution that the locking arm 52 can only move axially to reversibly lock the oblique bolt 3 .

[0072] Different from Embodiment 1, the claw arm 51 is not provided on the positioning post 5 but only the locking arm 52 is provided, so there is no transmission connection between the positioning post 5 and the driving arm 8 . The structure of the positioning column 5 is as Figure 12 As shown, the positioning column 5 includes a stem 53b fixedly connected to the rear side wall 1c, a sliding cover 54b covering the stem 53b, and a sliding cover 54b arranged between the stem 53b and the sliding cover 54b. The return spring 55b between them, the sliding cover 54b can only slide axially along the stem 53b and cannot rotate radially. Secondly, the groove 85 is not provided on the driving arm 8 , so there is no locked combination relationship between the first protruding pieces ( 323 a , 323 b ) and the driving arm 8 .

Abstract

Disclosed is a door lock which comprises a casing. The casing comprises a driving mechanism which is in linkage with a door handle and an oblique bolt which can close and lock a door. The oblique bolt comprises a rod portion in a general rod shape and a head which is arranged at the front end of the rod portion and has an oblique surface, a driving spring is arranged on the rod portion of the oblique bolt so as to drive the head of the oblique bolt to extend out of an opening formed on one side of the casing, the corresponding driving mechanism can move the rod portion of the oblique bolt, so that the head of the oblique bolt can retract inside the casing, the oblique bolt is reversibly locked inside the casing through a reversible locking mechanism, so that the direction of the oblique surface of the head of the oblique bolt can be determined through the closing direction of the door. According to the technical scheme, the rod portion and the driving mechanism form a linking combination, and the rod portion of the oblique bolt can be both locked and released by the aid of the reversible locking mechanism, so that quick direction shifting of the oblique bolt is achieved. The door lock can be applied to locking products with bolts having oblique portions.

Description

technical field [0001] The invention relates to a door lock, in particular to a door lock which can conveniently change the installation direction of an oblique lock bolt. Background technique [0002] A traditional room door lock has a housing and an oblique deadbolt disposed in the housing, wherein one wall at the top end of the oblique deadbolt is inclined, and the oblique deadbolt is slidably fixed in the housing. The oblique bolt is used to cooperate with the frame of the door leaf. When the door is closed, the inclined surface at the top end of the oblique bolt slides along the frame and is pressed into the housing of the lock body by the frame. The oblique bolt pops up and slides into the lock hole in the frame to lock the door leaf; when the door is opened, the door handle or lock knob is rotated to retract the oblique bolt into the lock body to open the door leaf. For this reason, the setting direction of the slant portion at the top end of the oblique bolt is rela...
