According to one aspect of the utility model, the direct current switch cabinet locking mechanism further comprises a lock cylinder and a cylinder base, the cylinder base is fixedly connected to the door plate, the lock cylinder is rotatably and movably arranged inside the cylinder base, and the lock tongue is fixedly connected with the lock cylinder.
According to one aspect of the utility model, the lock seat penetrates through the door panel, one end of the lock seat is provided with a lock tongue, and the other end of the lock seat is provided with a lock hole.
According to one aspect of the utility model, the bolt is fastened to the lock cylinder by a hex bolt.
According to an aspect of the present invention, the latch bolt includes a rotation part connected to the key cylinder, a locking part engaged with the recess, and a connection part connecting the rotation part and the locking part.
According to one aspect of the utility model, one side of the limiting groove close to the door frame is arranged in parallel to the locking plate, one side of the limiting groove far away from the door frame is obliquely arranged relative to the locking plate, and the distance from the side of the limiting groove far away from the door frame to the locking plate is gradually increased from the groove bottom of the limiting groove to the groove opening.
The implementation of the utility model has the advantages that: the direct-current switch cabinet locking mechanism comprises an XX direct-current switch cabinet and a door frame, the direct-current switch cabinet locking mechanism comprises a lock tongue which is rotatably and movably connected to the cabinet door, and a groove which can accommodate the lock tongue is formed in the door frame; the door frame is perpendicular to the cabinet door and is fixedly provided with a locking plate, and the joint of the spring bolt and the locking plate is provided with a limit groove which can be embedded into the locking plate, so that when the locking system receives impact forces on two sides of the cabinet door, the spring bolt is clamped on the locking plate through the limit groove, effective reaction force is provided for the impact forces on the two sides, and the locking system can have a good locking effect when receiving the impact forces on the two sides of the cabinet body.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of a locking mechanism of a dc switch cabinet according to the present invention;
fig. 2 is an external schematic view of a dc switch cabinet locking mechanism according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the direct current switch cabinet locking mechanism comprises a cabinet door and a door frame 1, the direct current switch cabinet locking mechanism comprises a lock tongue 2 which is movably connected to the cabinet door in a rotating mode, and a groove which can be incorporated into the lock tongue is formed in the door frame. When the lock tongue rotates until the lock tongue enters the groove, the lock state is achieved, and the cabinet door can be locked by the lock tongue arranged in the groove; when the bolt rotates to be out of the groove, the locking state is not achieved, and the cabinet door can be opened.
The door frame is perpendicular to the cabinet door is fixedly provided with a locking plate 3, and a limit groove which can be embedded into the locking plate is arranged at the joint of the lock tongue and the locking plate. When the spring bolt is rotatory to the locking state, the fixed plate has also been embedded in the spring bolt, and the spring bolt card is established on the lockplate during consequently locking state, and when receiving the impact force of cabinet door both sides, the lockplate can provide reaction force for the spring bolt for direct current switch cabinet locking mechanical system can guarantee better locking effect this moment, can not take place dangerous situations such as slide lock.
Because the lock tongue is the condition that the limiting groove is clamped on the locking plate in the rotating process, if the width of the limiting groove is just matched with the thickness of the locking plate, the notch of the limiting groove cannot be in butt joint with the locking plate in the rotating process. In order to enable the limit groove to smoothly clamp the locking plate, one side, away from the door frame, of the limit groove is obliquely arranged relative to the locking plate, and the distance from one side, away from the door frame, to the locking plate is gradually increased from the groove bottom of the limit groove to the groove opening. Meanwhile, the limiting groove can be tightly clamped on the locking plate, and one side, close to the door frame, of the limiting groove is parallel to the locking plate and is tightly attached to the locking plate.
The direct current switch cabinet locking mechanism further comprises a lock cylinder 4 and a cylinder base 5, the cylinder base is fixedly connected to the door plate, the lock cylinder is movably arranged inside the cylinder base in a rotating mode, and the lock tongue is fixedly connected with the lock cylinder. The lock core rotates to drive the lock tongue to rotate, so that a locking state or a non-locking state is realized.
The lock seat penetrates through the door plate, a lock tongue is arranged at one end of the lock seat, and a lock hole is formed in the other end of the lock seat.
The lock tongue and the lock cylinder are fastened through a hexagon bolt.
The spring bolt includes the rotating part of being connected with the lock core, with recess matched with sticking department and connect the connecting portion of rotating part and sticking department. In this embodiment, the rotating portion and the locking portion are both disposed parallel to the cabinet door, and the connecting portion is disposed perpendicular to the cabinet door. Because the recess on the door frame often is not on a plane with the rotating part, if connecting portion and rotating part direct connection, then can't cooperate with the recess. The locking parts are connected through the connecting parts, so that the locking parts can be matched with the grooves at corresponding positions.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
