Above-mentioned door lock due to spare and accessory parts more, there is complex structure, assembling inconvenience, the problems such as cost of production is high.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of new door lock, and it is simple that it has structure, is easy to assembling, the feature that cost of production is low.

For achieving the above object, the utility model provides following technical scheme: a kind of new door lock, comprise lock body, dead bolt, lock body comprises housing, shell one end is connected with the installation panel passed for dead bolt, described housing comprises upper cover plate and lower shoe, described dead bolt is connected with two parallel driving members in housing, also comprise the rotor by rotating for pulling driving member, described lower shoe is provided with baffle plate between two driving members, is connected with all the time by back-moving spring extrapolated for dead bolt between described baffle plate and dead bolt.

Described baffle plate is plugged between lower shoe and upper cover plate, and described lower shoe and upper cover plate are equipped with the slot for baffle plate grafting.

One end that described upper cover plate and lower shoe are mounted opposite panel is equipped with block tongue, and described installation panel is provided with the draw-in groove coordinating with block tongue and formed and connect and fix, and the other end that described upper cover plate and lower shoe are mounted opposite panel is connected by screw.

Described driving member is the catch being fixedly connected on dead bolt, and catch offers elongated hole, and described rotor is between two catch, and described rotor is provided with fanning strip, and the two ends of fanning strip contact at the other end of two relative dead bolts of elongated hole respectively.

The conflict tangent with baffle plate of described fanning strip.

The use procedure of the utility model door lock is as follows: prior art rotor is used for mounting handle, and the effect that dead bolt is subject to back-moving spring is in the state of stretching out all the time, namely sealed; Rotated by the rotation rotor driven of handle, rotor rotation can pull driving member, and driving member is fixedly connected with dead bolt, therefore drives dead bolt to shrink in housing, its unlocking condition simultaneously; The normal function of door lock can be realized by the program.And compare existing door lock, its structure is more simple, and spare and accessory parts are less, convenient for assembly, with low cost.And can all can embody from the following aspect, the back-moving spring of conventional door lock is installed on the outside of driving member, due to unbalance stress, single back-moving spring cannot reach the effect of active homing, therefore needs all to install back-moving spring on two driving members, while which increases spare and accessory parts, increase the volume of housing, add cost, the utility model door lock, structure is then compacter.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.

New door lock described in the present embodiment, as shown in Figure 1, comprise lock body, dead bolt 6, lock body comprises housing, shell one end is connected with the installation panel 3 passed for dead bolt 6, described housing comprises upper cover plate 1 and lower shoe 2, described dead bolt 6 is connected with two parallel driving members 8 in housing, also comprise the rotor 4 by rotating for pulling driving member 8, described lower shoe 2 is provided with baffle plate 7 between two driving members 8, is connected with all the time by back-moving spring 5 extrapolated for dead bolt 6 between described baffle plate 7 and dead bolt 6.

The use procedure of the utility model door lock is as follows: prior art rotor 4 is for mounting handle, and the effect that dead bolt 6 is subject to back-moving spring 5 is in the state of stretching out all the time, namely sealed; Rotated by the rotation rotor driven 4 of handle, rotor 4 rotation can pull driving member 8, and driving member 8 is fixedly connected with dead bolt 6, therefore drives dead bolt 6 to shrink in housing, its unlocking condition simultaneously; The normal function of door lock can be realized by the program.And compare existing door lock, its structure is more simple, and spare and accessory parts are less, convenient for assembly, with low cost.And can all can embody from the following aspect, the back-moving spring 5 of conventional door lock is installed on the outside of driving member 8, due to unbalance stress, single back-moving spring 5 cannot reach the effect of active homing, therefore needs all to install back-moving spring 5 on two driving members 8, while which increases spare and accessory parts, increase the volume of housing, add cost, the utility model door lock, structure is then compacter.

Enter one, as shown in Figure 2, described baffle plate 7 is plugged between lower shoe 2 and upper cover plate 1, and described lower shoe 2 and upper cover plate 1 are equipped with the slot 12 for baffle plate 7 grafting.Baffle plate 7 passes through the fixing of the convenient baffle plate 7 of mode of grafting, and be convenient to assembling, and baffle plate 7 all can be fixed to upper and lower two ends, fixed effect is reliable.

Further, the installation of upper cover plate 1 and lower shoe 2 is described further, as shown in Figure 2, one end that described upper cover plate 1 and lower shoe 2 are mounted opposite panel 3 is equipped with block tongue 11, block tongue 11 is in the structure of sticking up outward, described installation panel 3 is provided with the draw-in groove 31 coordinating with block tongue 11 and formed and connect and fix, and the other end that described upper cover plate 1 and lower shoe 2 are mounted opposite panel 3 is connected by screw.During installation, first the block tongue 11 of lower shoe 2 inserted the draw-in groove 31 of installation panel 3 and ajust, after installing interior fittings, again the block tongue 11 of upper cover plate 1 inserted the draw-in groove 31 of installation panel 3 and ajust, be connected by screw in the other end and lower shoe 2 again, only need one piece of screw can complete installation between upper cover plate 1 and lower shoe 2 by which, not only convenient for assembly, and reduce costs.

Further, the structure of driving member 8 is pulled to be described further to rotor 4, as shown in Figure 1, described driving member 8 is for being fixedly connected on the catch of dead bolt 6, catch offers elongated hole 81, described rotor 4 is between two catch, and described rotor 4 is provided with fanning strip 41, and the two ends of fanning strip 41 contact at the other end of the relative dead bolt 6 of two elongated holes 81 respectively.Fanning strip 41 contacts at the other end of the relative dead bolt 6 of elongated hole 81, and when rotor 4 forward or reverse, fanning strip 41 all can promote catch and move backward, thus draws in housing by dead bolt 6, realizes unblanking, and after release handle, dead bolt 6 is subject to back-moving spring 5 and acts on reset.Such lock can be commonly used to the door body of unblanking from inner side in bathroom etc. and use.

Further, as shown in Figure 1, the conflict tangent with baffle plate 7 of described fanning strip 41.Fanning strip 41 and the tangent conflict of baffle plate 7 better position rotor 4, and the fixed effect of rotor 4 is better.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
