Description

Vertical hinged door lock Technical Field The utility model relates to the field of locks, in particular to a vertical hinged door lock. Background The tool to lock is as the core safety element of the door body, and its stability and durability directly influence user experience. In the scenes such as metal frame glass door, timber, the tool to lock needs to realize the connection with the door body through the blotter usually-the blotter not only can cushion the rigid contact of lock body and door body, reduces wearing and tearing, can also assist fixed lock body and handle, avoids becoming flexible or shifting because of frequent operation leads to. In the prior art, for example, chinese patent No. CN217735110U discloses a lock structure of a metal frame glass door, in which an inner rubber pad and an outer rubber pad are used to isolate the contact surface between the lock body and the glass door, and a certain protection is provided by the soft material of the rubber pad. However, the rubber pad mounting structure in this patent still has the following significant drawbacks: 1 in the existing structure, the rubber pad is only fallen into the lock body mounting groove through the 'spacer pad' and is attached to the glass surface through the 'pad attaching', after long-term use, the transverse stress generated by frequent rotation of the lockset handle easily causes the rubber pad to slide or fall off along the lock body surface, and stable connection of the lock body and the door body cannot be ensured. 2. The binding force between the rubber pad and the glass door in the existing structure only depends on the friction force of the pad, and the handle is easy to sag due to gravity or rotational inertia after long-term use, so that the closing precision and the attractiveness of the lockset are affected. 3. The handle as an organic whole formula door handle of current structure, with the panel installation time need be through just can screw down the screw between handle and the panel with the screwdriver after exposing the screw hole with the handle rotation certain angle earlier and be connected, connected mode is complicated, and the screwdriver is fish tail panel surface easily when the installation simultaneously. 4. The door lock with the existing structure often has a back locking structure, but a user cannot intuitively judge the locking state of the current lockset. Disclosure of Invention The technical problem to be solved by the utility model is to provide a flat-open door lock aiming at the defects of the prior art. The flat-open door lock comprises an inner handle, an outer handle, a handle mounting mechanism, a lock rod structure and a counter locking mechanism, wherein the inner handle and the outer handle are correspondingly connected with each other, the handle mounting mechanism is used for connecting the inner handle and the outer handle, the lock rod structure is used for synchronously rotating the inner handle and the outer handle in a linkage mode, the counter locking mechanism is arranged at the inner handle, a state feedback mechanism is arranged at the outer handle and is in linkage with the counter locking mechanism, the state feedback mechanism comprises an outer transmission part and a state window, the outer transmission part is arranged in the outer handle in a rotating mode, the state window is arranged on the surface of one end, far away from the inner handle, of the outer handle, one end of the outer transmission part is synchronously rotated with the counter locking mechanism, at least one identification feature is arranged at the other end of the outer transmission part, and the state window is arranged on a rotating path of the identification feature. By adopting the technical scheme, the identification feature has the appearance with large visual difference compared with the adjacent part of the surface of the outer transmission part, such as color, graph, number, letter and the like, the action state of the inner handle counter-locking mechanism is transmitted to the state window on the surface of the outer handle through the outer transmission part, one end of the outer transmission part is linked with the counter-locking mechanism, the identification feature arranged at the other end rotates along with the outer transmission part, the state window is arranged on the surface of the outer handle and is positioned on the rotating path of the identification feature, when the counter-locking mechanism executes locking or unlocking action, the outer transmission part drives the identification feature to rotate, different identification features are sequentially displayed through the state window, the locking or unlocking state of the lockset can be observed through the state window by a user, the inconvenience that the traditional lockset needs to be in a test pushing or key verification state is solved, and the visual perception and the use safety of the lockset state o
