Summary of the invention

The purpose of this utility model is for providing a kind of Portable secure latch, the turn-button that can limit door lock rotates, use and avoid suffering the ruffian to invade, rent that room family suffers landlord, former tenant or copy the unintelligible dangerous person such as key as motivation take the revenge of harbouring a grudge with the intrusion of directly opening the door of existing key, to guarantee to rent the inhabitation safety of room family.

The purpose of this utility model is for a kind of Portable secure latch is provided, and is easy-to-use, need not destroy door lock and also need not re-assembly and can directly use, to promote the convenience that uses.

For reaching above-mentioned purpose, the utility model provides a kind of Portable secure latch, is sheathed on turn-button and the core of door lock, rotates in order to the turn-button that limits door lock, comprises a snap close body and a stator.The snap close body is provided with fitting portion, and fitting portion is to turn-button that should door lock, and stator is connected in a side of snap close body, and stator is provided with one and wears groove, wears the core of the corresponding door lock of groove.

In a preferred embodiment, the bottom surface of snap close body is provided with at least one strong magnets, and the bottom surface of stator is provided with at least one strong magnets, and fitting portion is cross or the flower type, and the snap close body is cuboid, and stator is rectangle.

The specific embodiment

Below by particular specific embodiment embodiment of the present utility model is described, the person skilled in the art can understand other advantage of the present utility model and effect easily by content disclosed in the present specification.

Referring to graphic explanation embodiment of the present utility model, it should be noted, below graphic for the signal of simplifying graphic, and basic conception of the present utility model only is described in a schematic way, but only the illustration structure relevant with the utility model but not component number, shape and size when implementing according to reality are drawn in graphic, kenel, quantity and the ratio of each element are not to illustrate to be limited during its actual implements, and can need to change according to actual design, close chat first bright.

At first, see also Figure 1 and Figure 2, Fig. 1 is the stereo appearance figure of the utility model Portable secure latch the first preferred embodiment, and Fig. 2 is the use state reference map of the utility model Portable secure latch the first preferred embodiment.As shown in the figure, Portable secure latch 1 of the present utility model is sheathed on turn-button 21 and the core 22 of door lock, rotates in order to the turn-button 21 that limits door lock, and Portable secure latch 1 includes a snap close body 11 and a stator 12.

Snap close body 11 is provided with fitting portion 110, the turn-button 21 that 110 pairs of fitting portions should door lock, and in the present embodiment, fitting portion 110 is cross, and snap close body 11 is cuboid, and the bottom surface of snap close body 11 is provided with a plurality of strong magnets 111.Stator 12 is connected in a side of snap close body 11, and stator 12 is provided with one and wears groove 120, wears the core 22 of groove 120 corresponding door locks, and in the present embodiment, stator 12 is rectangle, and the bottom surface of stator 12 is provided with at least one strong magnets 121.

As shown in Figure 2, when reality is used, Portable secure latch 1 of the present utility model is placed in the position of general door lock turn-button 21 and core 22, during use, snap close body 11 is 90 degree mutually with stator 12, the fitting portion 110 of snap close body 11 can just corresponding be inserted in the turn-button 21 of door lock, makes turn-button 21 be positioned at fitting portion 110, and the 120 energy correspondences of groove of wearing of stator 12 are sheathed on core 22 peripheries.And can be adsorbed on the door lock by

strong magnets

111 and 121, do not opened the door lock turn-button 21 and the rotation that are enclosed within the fitting portion 110 by the outside wish of door lock with restriction snap close body 11 and open.So design, when having the people to insert wish and rotate the door lock turn-button 21 of door lock with key from the door lock outside, fitting portion 110 can limit door lock turn-button 21 and rotate.Particularly, Portable secure latch 1 is set on the door lock turn-button 21 and the groove 120 of wearing of stator 12 is arranged on around the core 22, can limit door lock turn-button 21 and can not be subjected to outside want the application of force of opening door lock and rotate unlatching, prevent that by this door lock from opening door to reach antitheft and to promote the function of home safety by the outside through key or other special tool(s) wish.

Please consult again shown in Figure 3ly, fold state diagram when not using for the utility model Portable secure latch.As shown in the figure, Portable secure latch 1 overall structure of the present utility model is exquisite, and snap close body 11 and a stator 12 mutually doubling fold, be more convenient for carrying out using, can promote the convenience when using, the safety when lifting house-renter or business traveller stay.

In addition, in other different embodiment, the fitting portion 110 of the snap close body 11 of Portable secure latch 1 of the present utility model also can be flower type or other shape, and the quantity of

strong magnets

111 and 121 also visual different demand changes, what allow Portable secure latch 1 can be more firm is adsorbed on the metal surface around door lock turn-button 21 and the core 22, makes more strong fix of Portable secure latch 1.

Although aforesaid description and graphicly disclosed preferred embodiment of the present utility model, but must recognize variously increase, many modifications and replace and may be used in utility model and do preferred embodiment, and can not break away from spirit and the scope of the utility model principle that defines such as the application.The those skilled in the art that are familiar with the affiliated technical field of the utility model can know from experience, and the utility model can be used in the modification of many forms, structure, layout, ratio, material, element and assembly.Therefore, this paper should be regarded as illustrating the utility model in this embodiment that discloses, but not in order to limit the utility model.Scope of the present utility model should be defined by the application, and contains its legal equivalents, is not limited to previous description.
