Abstract
The utility model relates to a protecting device of an antitheft door lock, which belongs to the technical field of the door lock, and comprises a protecting rotating plate and a clamp spring, wherein the protecting rotating plate can rotate to a given angle to lock a door lock body and is fixed on a door lock panel through the clamp spring, the protecting rotating plate is fixed on a rotating column and is interlocked with the rotating column, and the rotating column is pivoted on the door lock panel, and is characterized in that a positioning rotation sheet is sleeved on the rotating column, the positioning rotation sheet is provided with at least two positioning holes facing towards the door lock panel, the door lock panel is provided with a corresponding pit, a ball bearing is embedded inside the hole, and a spring is arranged below the ball bearing. The protecting device of the antitheft door lock can limit the rotation of the protecting rotating plate, so the situation that the lock cannot be opened for the secure is locked by mistake can be effectively prevented, and through the sliding of the ball bearing, the protecting rotating plate rotates to a given angle, the hand feel is light and convenient, and the opening and closing are flexible.
Description
Technical field
The utility model belongs to the door lock technical field, is specifically related to the insurance institution of safe-guard door lock.
Background technology
The safeties of safe-guard door lock utilization at present is very extensive, when safeties are closed, can open door from outdoor use key, password or other modes.After in user's access door, safeties are opened, can not be opened door lock, like this to strengthen the safety of safe-guard door lock from outdoor application key, password etc.When especially sleep at night or vigilance reduce, can effectively prevent technology unlocking instruments such as master key, thereby increase the safety of the person and property.
The safeties of existing safe-guard door lock are installed on the Door lock casing, by jump ring, insurance flap and pad are formed, the insurance rotor is connected with the safe-guard door lock lock body, insurance is turned and is fixed on the lock panel by pad and jump ring, and when closing safeties, door lock is normally opened, to insure rotor and also revolve and turn 90 degrees, block Door lock.At this moment, door lock can't be opened from outdoor.
But existing safeties have also brought potential safety hazard when increasing the door lock safety.Traditional safeties lean on clockwise or are rotated counterclockwise 90 degree and block lock body.Because door and door lock are to be in the continuous bump active state, safeties are subjected to external force vibration to cause rotating for a long time and block lock body, outdoor can not opening the door by normal mode in the use.Can only unblank by violence, cause any property loss and inconvenience.
Summary of the invention
The utility model purpose is the defective of easily clashing into self-locking for the safe-guard door lock safeties that solve prior art, and a kind of safeties of safe-guard door lock of simple in structure, reliable operation are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of safeties of safe-guard door lock, it comprises the insurance flap and the jump ring of the chucking Door lock that rotates to an angle, the insurance flap is fixed in Door lock casing by jump ring, the insurance flap be fixed in column spinner and with its interlock, column spinner is installed in Door lock casing, it is characterized in that being socketed with on the column spinner location rotor, the location rotor is provided with at least two towards the Door lock casing locating hole, Door lock casing is provided with the pit that adapts, and is embedded with ball in the hole, and ball is spring down.
Further, described location rotor is provided with 4 locating holes, and is along the circumferential direction uniform.
The utility model door lock safeties compared to existing technology, beneficial effect mainly shows the rotary spacing that is the insurance flap, effectively avoids insuring the situation that the mistake lock can't be opened, and slides by ball, make insurance flap certain angle rotation feel light, open and close flexibly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The safeties of safe-guard door lock are by pad 1, and jump ring 2 insures flap 3, and location rotor 4 and Door lock surface plate 8 are formed.Wherein locate rotor 4 and be provided with at least one locating hole 5.
Lock panel has hole slot in the position that is fit to, and ball 6 is placed in it, and ball 6 has spring 7.Location rotor 4 is fixed in insurance flap 3, and insurance flap 3 is by pad 1, and jump ring 2 is fixed in lock panel 8.
Insure non-enable possition, ball 6 is positioned at the locating hole 5 of location rotor 4, relies on the effect of spring 7 to contact with location rotor 4 down, and the insurance flap is produced fixation, and the vibration of avoiding the activity of door lock to produce causes insuring flap and rotates.
To insure flap and rotate to the insurance enable possition, location rotor 4 rotates thereupon, the part of ball 6 enters in another locating hole 5 of locating on the rotor 4, this moment, safeties were had an effect, insurance flap 3 promotes insurance interlock plate 11 and blocks dead bolt fixed mount 10, main dead bolt 9 fixed-site are motionless, can not open outdoor.
Based on spirit of the present utility model, the safeties structure of this safe-guard door lock also has multiple variation, can be the column that helps sliding as ball, or the locating hole 5 of location rotor 4 to arrange its differential seat angle on circular rotor can be 90 to spend or other angles.All this type of all equivalences change, all should be in the claim of the present patent application.
