Abstract

The utility model relates to two sets or more than two sets of lock positioning devices respectively composed of a switch component (1) and a positioning tongue sheet component (2). The utility model uses a roller provided with a bolt driver slot to confirm the positioning of locks, and the roller is led into a positioning slot and triggers a magnetic reed pipe switch in the positioning slot. The utility model has the advantages of simple structure, convenient adjustment and accurate positioning.

Description

The positioner of lock

The utility model relates to a kind of positioner of lock, relates in particular to the positioner that magnetic force is sheared door lock and latch lock.

At present, the patent No. of having authorized is a kind of safe magnetic door lock positioner of " 96229203.6 ", as Fig. 5, Figure 6 and Figure 7, this device is one group and constitutes by being contained in the slide unit 4 on the door leaf and being contained in switch block 5 on the doorframe, head, the middle part of the screw rod 41 of slide unit 4 and externally threaded lower part is arranged, but the rotatable roller 40 of suit, spring 42 and can adjust the nut 43 that roller 40 changes with screw rod 41 upper-lower positions respectively; Switch block 5, it has a fixed mount 50 that can be fixed on the doorframe, in the through hole 53 in the middle of the fixed mount 50 trigger switch 52 is installed, a wedge slide block 51 that can allow roller 40 slip in the through hole 53 along its inclined-plane and make trigger switch 52 closures is arranged respectively in the both sides of fixed mount 50.

This structure all adopts one group to be the location of door lock, after door leaf and the variation of doorframe relative position door leaf is tilted, and this moment, roller 40 did not slip into through hole 53 fully, and made trigger switch 52 closures, then sent door by mistake and shut information; If in the roller 40 permanent magnet is housed, and trigger switch 52 adopts the magnetic red pipe as one group of location, because of the magnetic red pipe starts a scope is arranged, when roller 40 just will slip in the through hole 53, magnetic flux was the lower limit within the scope, and the magnetic red pipe is started, through test, this moment, door leaf misplaced in doorframe 5mm～10mm, and promptly Men Wei closes, and did not therefore also reach the requirement of accurate location door lock; Above-mentioned a kind of safe magnetic door lock positioner when adjusting roller 40 height, be pulled down switch block 4 just and can finish from doorframe, makes troubles for like this adjustment work.

In sum, prior art exists positioner and adjusts inconvenience, the problem that the location of door lock is not accurate enough.

The purpose of this utility model is to overcome the prior art shortcoming, and a kind of positioner of lock of simple in structure, easy to adjust, accurate positioning is provided.

The utility model is to realize like this.

The utility model is made of switch block and allocation tongue chip part, in switch block interfix groove, the magnetic red pipe can be set, a built-in permanent magnet can be arranged at the screw rod top in the allocation tongue chip part, and have a roller of spiral shell cutter groove, perhaps its roller be insulation and have a spiral shell cutter groove, permanent-magnet block is set in screw rod, makes magnetic red pipe closure, just send the validation of information door lock and accurately locate when roller slips into locating slot.Because have spiral shell cutter groove on the roller, available spiral shell cutter is adjusted the relative position of roller and locating slot easily, overcome the inconvenience that prior art is adjusted.

Accurately closed in order to reach door leaf and doorframe, as shown in Figure 1, adopted two groups of the utility model structures to be arranged on the lock-bit both sides, promptly, two switch blocks 1 are installed on the doorframe 30, on the door leaf 3 with switch block 1 opposite position on its can close-fitting installing and locating tongue spare 2; Two groups of above the utility model structures also can be set on door leaf and the doorframe, wherein any one group is sent locating information for the magnetic red pipe, and all the other groups are sent locating information for the contact switch of not establishing permanent magnet and magnetic red pipe, and above-mentioned each information is gone here and there and connected back affirmation door lock mutually and accurately locatees.According to two one line principles, the frame mode more than two groups and two groups can reach the reliable location of lock, has overcome one group of location problem of misalignment easily takes place.

The utility model adopts one or more groups location, can be applicable to different occasions.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is that the utility model is installed in a last structural representation;

Fig. 2, Fig. 3 are the structural representations of switch block 1 among Fig. 1;

Fig. 4 is the structural representation of allocation tongue parts 2 among Fig. 1;
