Description
Technical field
The utility model relates to a kind of locking mechanism of electronic lock, particularly relates to a kind of locking mechanism that can prevent the high security of outside destroy.
Background technology
Current electronic lock is all directly use electromagnet or motor as locking mechanism, and this mechanism is when being subject to outside destroy, and destructive external force will directly act on electromagnet or motor itself.Because the intensity of electromagnet and motor itself is relatively low, be therefore destroyed than being easier to.Therefore current electronic lock is all destroyed than being easier to when outside destroy is attacked, thus causes electronic type coded lock illegally to be opened.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of locking mechanism of high security, can prevent outside destroy from unblanking, greatly improve safety, and structure is simple, is easy to realize.
The utility model is solve the problems of the technologies described above the locking mechanism that the technical scheme adopted is to provide a kind of high security, comprise motor, screw shaft and driving slide block, described screw shaft is arranged in the rotating shaft of motor, the cavity body holding screw shaft is provided with in described driving slide block, wherein, described screw shaft is provided with safety pin spring, deformed spring is arranged with outside described screw shaft, together with described safety pin spring offsets with deformed spring, described deformed spring, screw shaft and safety pin spring are contained in the cavity body driving slide block together.
The locking mechanism of above-mentioned high security, wherein, described screw shaft is arranged in the rotating shaft of motor by the axial circular hole of its end, and described safety pin spring is located in the radial circular hole in the middle part of screw shaft.
The locking mechanism of above-mentioned high security, wherein, described deformed spring comprises turn body, and the two ends of described turn body are equipped with one with described turn body around to contrary back-roll turn.
The utility model contrast prior art has following beneficial effect: the locking mechanism of the high security that the utility model provides, by arranging safety pin spring on screw shaft, and sheathed deformed spring, described safety pin spring and deformed spring abut against in the cavity body being contained in together with screw shaft after touch and driving slide block, locking mechanism is locked by slide block, therefore when outside destroy is attacked, external force cannot directly act on more fragile motor itself, thus the ability of electronic lock collapse resistance is improved greatly, various types of electronic lock can be widely used in.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the locking mechanism decomposing schematic representation of the utility model high security.
Refer to Fig. 1, the locking mechanism of the high security that the utility model provides comprises motor 1, screw shaft 2 and drives slide block 4, described screw shaft 2 is arranged in the rotating shaft of motor 1, the cavity body holding screw shaft 2 is provided with in described driving slide block 4, wherein, described screw shaft 2 is provided with safety pin spring 3, deformed spring 5 is arranged with outside described screw shaft 2, together with described safety pin spring 3 offsets with deformed spring 5, described deformed spring 5, screw shaft 2 and safety pin spring 3 are contained in the cavity body driving slide block 4 together.
The locking mechanism of the high security that the utility model provides, wherein, described screw shaft 2 is arranged in the rotating shaft of motor 1 by the axial circular hole of its end, and described safety pin spring 3 is located in the radial circular hole in the middle part of screw shaft 2.Described deformed spring 5 comprises turn body 51, and the two ends of described turn body 51 are equipped with one with described turn body around to contrary back-roll turn 52.
Fig. 2 is the locking mechanism open mode schematic diagram of the utility model high security; Fig. 3 is the cross-sectional view along A-A line in Fig. 2.
Refer to Fig. 2 and Fig. 3, when needs locking mechanism is opened, first motor 1 rotates forward, and drives screw shaft 2 to rotate forward, and drives safety pin spring 3 to rotate forward.Safety pin spring 3 forward along deformed spring 5 around to motion, compression deformed spring 5, until the back-roll structure place of deformed spring 5, motor 1, screw shaft 2 and safety pin spring 3 are all in idling conditions.Now deformed spring 5 arrives most compressed state.The elastic force of the deformed spring 5 after compression makes to drive slide block 4 to move backward, and namely locking mechanism is in open mode.
Fig. 4 is the locking mechanism closed condition schematic diagram of the utility model high security; Fig. 5 is the cross-sectional view along B-B line in Fig. 4.
Refer to Fig. 4 and Fig. 5, when needs locking mechanism is closed, first motor 1 reverses, and drives screw shaft 2 to reverse, and drives safety pin spring 3 to reverse.Safety pin spring 3 oppositely along deformed spring 5 around to motion, reverse compression deformed spring 5, until the back-roll structure place of deformed spring 5, motor 1, screw shaft 2 and safety pin spring 3 are all in idling conditions.Now deformed spring 5 arrives reverse most compressed state.The elastic force of the deformed spring 5 after compression makes to drive slide block 4 to travel forward, and namely locking mechanism is in closed condition.
The utility model locking mechanism, realizes closing and open mode by driving seesawing of slide block 4.Drive seesawing of slide block 4 not to be by motor 1 Direct driver, but drive slide block 4 to move by the elastic force of deformed spring 5 after compressing deformed spring 5 by motor 1.Therefore slide block 4 is driven directly not contact with motor 1, when there being this locking mechanism of outside destroy, destructive external force can only act on the larger driving slide block 4 of intensity, cannot act on the lower motor of intensity 1, thus the safety of locking mechanism is increased greatly.Simultaneously; because deformed spring 5 has former and later two back-roll structures; this structure not only accurately can control the stroke driving slide block 4, can be in idling conditions instead of locked rotor condition, thus motor 1 can be protected can not to damage because of larger locked rotor current when motor 1 can also be made to arrive range.Therefore not only safety is high for the utility model locking mechanism, and dependability is also very high, and the locking mechanism that can effectively prevent outside destroy from causing lost efficacy, thus made locking mechanism safer.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
