Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 6, the tapered end protection mechanism of a kind of door lock of the present utility model, comprise tapered end panel 1 and tapered end slip lid 2, described tapered end slip lid 2 is arranged at the surface of tapered end panel 1 and is slidably connected with tapered end panel 1, the medial surface top and the bottom of described tapered end slip lid 2 are respectively arranged with back-off groove 21 and lower back-off groove 22, the bottom of described tapered end slip lid 2 offers pressure shell fragment hole 23, the bottom of described tapered end panel 1 is provided with elasticity hinge 3, this elasticity hinge 3 comprises shell fragment 31, the top of described shell fragment 31 is provided with positive stop end 311, this positive stop end 311 is connected to the medial surface of described tapered end slip lid 2, when described tapered end slip lid 2 slides relative to tapered end panel 1, described positive stop end 311 can be connected in back-off groove 21 or lower back-off groove 22.During concrete use, the position, pressure shell fragment hole 23 offered bottom tapered end slip lid 2 with mechanical key 4 is inserted, until the shell fragment 31 of lower compression elasticity hinge 3, the positive stop end 311 of shell fragment 31 is made to exit the lower back-off groove 22 of tapered end slip lid 2, then slide downward tapered end slip lid 2, after tapered end slip lid 2 slide downward one segment distance, it is spacing that the upper back-off groove 21 that the positive stop end 311 of shell fragment 31 is connected to tapered end slip lid 2 completes tapered end slip lid 2, thus complete opening tapered end slip lid 2, and effectively avoid tapered end slip lid 2 to deviate from the connection with tapered end panel 1 completely, in this case, external power supply or mechanical key 4 can be used to unblank, after completing and unblanking, again can slide tapered end slip lid 2 by 2-in-1 for tapered end slip lid.Now, machinery uses the shell fragment 31 of mechanical key 4 times compression elasticity hinges 3, and the positive stop end 311 of shell fragment 31 is deviate from and the abutting of upper back-off groove 21, then whole tapered end slip lid 2 can deviate from the connection with tapered end panel 1, completes the fractionation to tapered end panel 1 and tapered end slip lid 2.
During assembling the present embodiment, first by the precompressed of elasticity hinge 3 shell fragment 31, again tapered end slip lid 2 and lock panel are slipped, when tapered end slip lid 2 up slides relative to tapered end panel 1, locate with the upper back-off groove 21 of tapered end slip lid 2 under the active force of the positive stop end 311 of shell fragment 31, continue tapered end slip lid 2 to coordinate with tapered end panel 1 up to slide, when the lower back-off groove 22 of tapered end slip lid 2 moves to positive stop end 311 place of shell fragment 31, again under the active force of the positive stop end 311 of shell fragment 31, tapered end slip lid 2 is fixed with tapered end panel 1, complete and installation is covered to tapered end panel 1 and tapered end slip lid 2.
The tapered end protection mechanism of the door lock of the present embodiment, by the improvement design of tapered end panel 1 and tapered end slip lid 2 structure, the tapered end panel 1 after closing and tapered end slip lid 2 can be effectively made to form integral structure, the mechanical lock head of door lock and external electrode are hidden in the inside of tapered end the panel 1 and tapered end slip lid 2 closed, cannot damage mechanical lock head and external electrode easily, reach protection anti-theft effect to greatest extent.
In the present embodiment, described elasticity hinge 3 also comprises stator 32 and torque spring 33, and this stator 32 is fixedly installed in the bottom of tapered end panel 1 by screw 34, and described shell fragment 31 is connected with stator 32 by this torque spring 33; Concrete, shell fragment 31 is provided with rotating shaft, stator 32 end winding forms axis hole, torque spring 33 is sheathed in rotating shaft, rotating shaft and axis hole are rotationally connected, the end abutment of torque spring 33 is in shell fragment 31, apply elastic force on shell fragment 31, shell fragment 31 is made to have elastic restoring force, thus effectively can guarantee that the positive stop end 311 of shell fragment 31 can be connected to the medial surface of tapered end slip lid 2 all the time, and when making tapered end slip lid 2 slide relative to tapered end panel 1, the positive stop end 311 of shell fragment 31 can be connected in back-off groove 21 or in lower back-off groove 22.
In the present embodiment, the both sides of described tapered end panel 1 offer chute 11, and the both sides, inside of described tapered end slip lid 2 are provided with guide rail 24, and guide rail 24 and chute 11 are slidably connected tapered end slip lid 2 and tapered end panel 1 are slidably connected; Concrete, the formula mode of guide rail 24 and chute 11 is conducive to the slip between tapered end slip lid 2 and tapered end panel 1, and slip smooth degree is better, and stationarity is better.
Preferably, described positive stop end 311 is in circular shape, and because upper back-off groove 21 and lower back-off groove 22 are reverse buckling type structure, the positive stop end 311 of circular shape is more conducive to skid off back-off groove 21 and lower back-off groove 22, facilitate tapered end slip lid 2 relative to tapered end panel 1 upward sliding, promote and use comfort.
Known the utility model is have above-described good characteristic in sum, is made it in use, promotes in conventional art the usefulness that do not have and has practicality, becoming the product that has practical value.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
