Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

Example (b):

the passage door safety lock is shown in the attached drawings 1-3 and comprises a passage door 1, a door lock 2, a bolt 3 and a lock box 4, wherein a mounting groove 101 is formed in the passage door 1, the lock box 4 comprises a bottom plate 401, a mounting plate 402 and a protective cover 403, the door lock 2 is fixedly mounted on the bottom plate 401, the bottom plate 401 is rotatably connected with the inner wall of the mounting groove 101 through hinges 5, the upper surface and the lower surface of the protective cover 403 are movably riveted with the mounting plate 402, the protective cover 403 can rotate along the mounting plate 402 and mutually cover the mounting plate 402, and the bolt 3 is movably mounted below the mounting groove 101 through a pin buckle 6.

Referring to fig. 4 and 5, the bolt 3 is provided with a right-angle handle 301.

Referring to fig. 6 and 7, a lock cylinder baffle 7 is movably hinged to one side of the mounting plate 402 away from the door lock 2 through a rivet, and a handle 8 is further arranged on one side of the mounting plate 402 away from the door lock 2.

Preferably, the mounting plate 402 is a hollow square steel.

Preferably, the length and height of the bottom plate 401 are slightly less than those of the installation groove 101.

When the outer side of the channel door 1 is opened, the lock cylinder baffle 7 hinged on the bottom plate 401 is pulled to open, the lock cylinder of the door lock is exposed, the door lock 2 is opened, the bottom plate 401 is pushed by the handle 8 to rotate from the mounting groove 101 to the inner side of the channel door 1, then the right-angle handle 301 of the bolt 3 is rotated out of the mounting groove 101, and the right-angle handle 301 is pulled to open the channel door 1; when the door is opened from the inner side of the access door 1, the protective cover 403 is firstly rotated out of the mounting plate 402 to expose the door lock 2 and open the door lock 2, then the bottom plate 401 is rotated out from the mounting groove 101 to the inner side of the access door 1, then the right-angle handle 301 of the bolt 3 is rotated out from the mounting groove 101 and the right-angle handle 301 is pulled to open the access door 1, and conversely, when the passage door 1 is closed, firstly, the bolt 3 is shifted through the right-angle handle 301, the bolt 3 locks the passage door 1, then the bolt 3 is rotated, the right-angle handle 301 is rotated into the installation groove 101, then the bottom plate 401 is rotated, the bottom plate 401 is rotated into the installation groove 101, the door lock 2 is locked, then the protective cover 403 is rotated, the protective cover 403 is buckled on the installation plate 402, at this time, since the right-angle handle 301 is arranged at the bottom of the mounting groove 101, the lock box 4 can limit the rotation of the right-angle handle 301, thereby limiting the movement of the bolt 3 and opening the access door 1 only after the door lock 2 is opened and the lock case 4 is rotated out of the installation groove 101.

It should be further explained that the length and height of the bottom plate 401 are slightly smaller than the length and height of the installation slot 101, and the gap between the bottom surface of the bottom plate 401 and the bottom surface of the installation slot 101 is slightly larger than the thickness of the right-angle pull 301, so as to ensure that the lock box 4 can be rotated out of the installation slot 101.

To sum up, this novel lock 2 is fixed on lock box 4, through the rotation of lock box 4 restriction right angle handle 301 to restriction access door bolt 3's activity, lock box 4 is opened the back, adopts the mode of stirring bolt 4 to open the door, and door lock 2 does not receive external force influence at access door 1 switch in-process, non-deformable, and lock box 4 can play rain-proof dust proof's effect to lock 2, prevents that lock 2 from damaging, consequently, the utility model discloses especially adapted uses under the open-air environment of field construction.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention.
