Detailed Description

As shown in fig. 1-4, a simple handle lock structure comprises an inner handle support 10 and an outer handle support 20 which are oppositely arranged, handles are respectively arranged on the outer sides of the inner handle support 10 and the outer handle support 20, a linkage unlocking mechanism 11 which is connected with the handles is respectively arranged on the inner sides of the inner handle support 10 and the outer handle support 20, and a sliding locking piece 12 which is used for limiting the rotation of the linkage unlocking mechanism 11 is arranged on the inner handle support 10.

The sliding locking member 12 is provided with a "U" shaped groove 121 at one end near the linkage unlocking mechanism 11, and two sides of the "U" shaped groove 121 are provided with a limiting portion 124 for limiting the rotation of the linkage unlocking mechanism 11.

The inner side of the inner handle support 10 is provided with a blocking post 13 for limiting the sliding distance of the sliding locking member 12.

The inner handle support is characterized by further comprising a transmission shaft 30, the linkage unlocking mechanism 11 is provided with a shaft hole 111, two ends of the transmission shaft 30 are respectively connected with the shaft hole 111 on the inner handle support 20 and the inner handle is linked, and if the linkage unlocking mechanism 11 of the inner handle support 10 is limited by the sliding locking piece 12 to move, the inner handle cannot rotate and the outer handle linked with the inner handle cannot rotate.

The push-pull member 40 and the shaft hole 111 are not on the same axis, i.e. the push-pull member 40 is biased to the left or right, which is convenient for the user to push the push-pull member 40 and is not blocked by the handle.

In the embodiment 1 shown in fig. 2, a guiding rail 14 is disposed on the inner side of the inner handle support 10, the sliding locking member 12 is disposed in the guiding rail 14 and is fixedly connected with the push-pull member 40 on the outer side of the inner handle support 10 by a screw 123, so that the screw 123 can be screwed into the push-pull member 40 to shorten the distance between the sliding locking member 12 and the push-pull member 40, the guiding rail 14 is relatively low, and therefore, a retaining portion 125 is formed by bending upwards at the end of the limiting portion 124, when the push-pull member 40 is pushed, the push-pull member 40 drives the sliding locking member 12 to move, so that the retaining portion 125 abuts against the linkage unlocking mechanism 11, and the linkage unlocking mechanism 11 is limited at this time, so that the inner handle and the outer handle cannot be rotated to unlock, thereby realizing the door locking function.

As shown in embodiment 2 of fig. 3, a guiding rail 14 is disposed on the inner side of the inner handle support 10, the sliding locking member 12 is disposed in the guiding rail 14, a groove is disposed at one end of the sliding locking member 12 away from the linkage unlocking mechanism 11, a protrusion 122 extends from the groove outwards, a push-pull member 40 is disposed on the outer side of the inner handle support 10, the protrusion 122 bends towards the outer side of the inner handle support 10 and is clamped with the push-pull member 40, the bending portion of the protrusion 122 extends into a hole of the push-pull member 40 to be linked with the push-pull member 40, the push-pull member 40 is pushed, the sliding locking member 12 is also pushed to be clamped with the linkage unlocking mechanism 11, rotation of the linkage unlocking mechanism 11 is limited, so that the inner handle cannot be rotated to unlock, the opposite outer handle cannot be rotated to unlock, a door locking function is realized, a cover plate (not shown) is disposed on the inner side of the inner handle support 10 relative to the sliding locking member 12, and the cover plate covers the sliding locking member 12 and is fixedly connected with the inner handle support 10, and the push-pull member 40 is prevented from being separated from the guiding rail 14.

As shown in fig. 4, in embodiment 3, a guiding rail 14 is disposed on the inner side of the inner handle support 10, a sliding locking member 12 is disposed in the guiding rail 14, a groove is disposed at one end of the sliding locking member 12 away from the linkage unlocking mechanism 11, a protrusion 122 extends outwards from the groove, an opening is disposed at the bottom end of the inner handle support 10, the protrusion 122 passes through the opening, the protrusion 122 directly extends out of the support of the inner handle, the door locking and opening functions can be realized by pushing and pulling the protrusion 122, the use is convenient, a cover plate (not shown) is disposed on the inner side of the inner handle support 10 opposite to the position of the sliding locking member 12, and the cover plate covers the sliding locking member 12 and is fixedly connected with the inner handle support 10 to prevent the push-pull member 40 from separating from the guiding rail 14.

The utility model provides a simple handle lock structure, which is convenient to operate, has the characteristics of simple structure, convenient processing and easy assembly, and has low cost, strong practicability and convenient installation.
