Description

Structure for preventing violent unlocking

Technical Field

The utility model relates to the field of electronic door lock structures, in particular to an anti-violent unlocking structure.

Background

The pivot subassembly in the electronic door lock structure is the mechanical structure that mainly used control tool to lock is opened and is closed, and pivot subassembly mainly includes: screw, screw sleeve, pivot, panel and handle, pivot subassembly rotates in panel blocking point within range, realizes controlling the opening and closing action of lock through handle drive pivot rotation.

However, because the traditional rotating shaft assembly rotates under violence, the blocking point can be blocked by the panel blocking point on the panel and then is broken, the handle can rotate 360 degrees, and finally the mechanical lock body is opened, and the electronic door lock with the structure does not have the function of preventing violent unlocking.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides an anti-violent unlocking structure, which aims to solve the technical problems that: the traditional electronic door lock does not have the function of preventing violent unlocking.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a structure that anti-riot unblank, includes handle, panel and pivot, the handle is assembled through pivot and panel, fixedly connected with dop in the pivot, the fracture groove has been seted up on the dop, fixedly connected with keeps off the point in the pivot, fixedly connected with panel stops the point on the panel, the panel stops the point and is located the removal route that keeps off the point, the draw-in groove has been seted up on hand, dop and draw-in groove block are connected, the fracture stress of dop is less than the fracture stress that keeps off the point.

Preferably, the number of the blocking points is two.

Preferably, the panel blocking point comprises two truncated arc sections, and the blocking point is arranged in the interval between the two corresponding truncated arc sections.

Preferably, the number of the breaking grooves is four.

Preferably, the screw sleeve is assembled in the rotating shaft, the stepped surface is arranged in the clamping head, one end of the screw sleeve is abutted against the stepped surface of the clamping head, the screw is arranged in the screw sleeve in a penetrating manner, one end of the screw is abutted against the screw sleeve, the other end of the screw is in threaded transmission connection with the handle, and the panel is positioned between the handle and the rotating shaft.

The utility model has the technical effects and advantages that: if the handle receives violent rotation, the power that the handle received is very big this moment, because four fracture grooves have been seted up on the dop, the existence in fracture groove can reduce the holistic fracture stress's of dop upper limit, so when the handle receives violent rotation, the dop can at first take place to fracture in the draw-in groove, again because screw sleeve hangs on the step of dop, fracture groove takes place fracture back with the dop, the pivot, screw sleeve still is connected through the screw, but dop and draw-in groove hookup location fracture, 360 rotations just can not drive the pivot rotation again when the handle is 360 rotations this moment, thereby realized not utilizing the pivot to open, the action of closing the door, practicality when can improve this product to preventing violent unblanking.

Detailed Description

Examples

Referring to fig. 1-6, an anti-violent unlocking structure comprises a handle 1, a panel 2 and a rotating shaft 3, wherein the handle 1 is assembled with the panel 2 through the rotating shaft 3, a clamping head 7 is fixedly connected to the rotating shaft 3, a breaking groove 8 is formed in the clamping head 7, a blocking point 6 is fixedly connected to the rotating shaft 3, a panel blocking point 10 is fixedly connected to the panel 2, the panel blocking point 10 is located on a moving path of the blocking point 6, a clamping groove 9 is formed in the handle 1, the clamping head 7 is connected with the clamping groove 9 in a clamping mode, and breaking stress of the clamping head 7 is smaller than that of the blocking point 6.

As shown in fig. 6, the panel blocking point 10 is divided into a panel blocking point 10a, a panel blocking point 10b, a panel blocking point 10c and a panel blocking point 10d, and the blocking point 6 is placed between the panel blocking point 10a and the panel blocking point 10c or between the panel blocking point 10b and the panel blocking point 10 d.

There are two catch points 6.

The panel blocking point 10 comprises two truncated arc sections, and the blocking point 6 is arranged in the interval between the two corresponding truncated arc sections.

The number of the breaking grooves 8 is four.

The screw sleeve 4 is assembled in the rotating shaft 3, the step surface is arranged in the clamping head 7, one end of the screw sleeve 4 is abutted against the step surface of the clamping head 7, the screw 5 is arranged in the screw sleeve 4 in a penetrating manner, one end of the screw 5 is abutted against the screw sleeve 4, the other end of the screw 5 is in threaded transmission connection with the handle 1, and the panel 2 is positioned between the handle 1 and the rotating shaft 3.

When the product is used, the two blocking points 6 are respectively inserted into the intervals between the corresponding arc sections, and the rotation angle of the two blocking points 6 can be limited by designing the length of the interval between the two arc sections, so that the rotation angle of the handle 1 can be adjusted; when the handle is normally used, a user grasps the handle 1, the handle 1 is forced to rotate, the handle 1 can drive the rotating shaft 3 to rotate to unlock through the clamping fit between the clamping head 7 and the clamping groove 9, and the rotating shaft 3 drives the blocking point 6 to rotate in the corresponding arc section so as to limit the rotating angle of the handle 1 in a normal state; if handle 1 receives violent rotation, the power that handle 1 received is very big this moment, because offer four fracture groove 8 on the dop 7, the existence of fracture groove 8 can reduce the holistic fracture stress's of dop 7 upper limit, so when handle 1 receives violent rotation, dop 7 can at first take place to fracture in draw-in groove 9, again because screw sleeve 4 hangs on the step of dop 7, fracture groove 8 takes place fracture back with dop 7, pivot 3, screw sleeve 4 will handle 1 through screw 5 connection, can take place relative rotation through screw sleeve 4 and pivot 3 when handle 1 rotates, the dop 7 breaks with draw-in groove 9 hookup location, 360 rotatory time just can not drive pivot 3 rotation of handle 1 this moment, thereby realized not utilizing pivot 3 to open, the action of closing the door, can improve the practicality of this product when unblanking to preventing violent unlocking from this.
