Description

A kind of glass door lock

Technical field

The utility model relates to a kind of anti-theft tool, is specifically related to a kind of glass door lock.

Background technology

People can install lock, to guarantee own property safety usually in order to avoid theft on door; Present stage, continuing to bring out of various new-type buildings caused the continuous appearance of various new-type doors, and for example, for attractive in appearance, market, retail shop adopt glass door, thereby the various locks that are used for glass door occurred mostly.

Glass gate lock on the market generally all is to adopt the latch form now, its internal construction complexity, assembling difficulty.And because the lock housing of the positive limit of its lockset and secondary can not be general, aspect production, make mould respectively, make number of molds increase, increase cost of production greatly.And this kind glass door lock is extracted latch out then owing to need unblank earlier, door could be opened complicated operation; Simultaneously, because lock leaks outside for a long time, be corroded easily and influence attractive in appearance.

Summary of the invention

At above-mentioned technical problem, the purpose of this utility model is, a kind of glass door lock is provided, and satisfying under the prerequisite of instructions for use, by simple structure design, has realized the convenience of operation, and the quantification production of lower cost.

For achieving the above object, the utility model adopts following technical scheme:

A kind of glass door lock comprises positive limit lock housing, secondary lock housing, and described positive limit lock housing is provided with and can aligns the tapered end that the limit lock housing is rotated mutually for what key inserted, and lock housing inside, described positive limit is provided with:

One contiguous block;

One pivot connects the medial extremity and the load of described contiguous block pivot of described tapered end, and the turning cylinder of described pivot staggers mutually with the turning cylinder of described tapered end and parallel;

One lock is fixedly connected on the described contiguous block.

The utility model can also carry out following operation and further optimize:

Described contiguous block is provided with a slotted hole, and described pivot passes described slotted hole described contiguous block and the load of described tapered end pivot are connect.

The medial extremity of described tapered end is provided with a shifting block, the fixedly connected described tapered end of one end, and the other end connects by described pivot and the load of described contiguous block pivot.

Described shifting block is fixed on the medial extremity of described tapered end by a jump ring.

Described contiguous block can horizontally slip along the inside of described positive limit lock housing.

Lock housing inside, described positive limit also is provided with spring, and described spring one end overlaps described pivot, and the other end connects described contiguous block.

Described positive limit lock housing and described secondary lock housing are the cube structure of inner opening, and both relative faces all are provided with the lockhole that can supply described lock to pass.

The glass door lock that the utility model is set forth, its beneficial effect is: this glass door can be at the contiguous block of positive limit lock housing slides within being provided with in the lock, and the slip of contiguous block is that the rotation by tapered end drives, simplified the internal structure of lockset, not only convenient the manufacturing installed, and simplified operation; Simultaneously, the positive limit lock housing of lock of the present utility model and secondary lock housing appearance profile structure are identical, can adopt identical mould to make, and have reduced number of molds, thereby have saved the cost of production of the utility model lockset greatly.

Description of drawings

Fig. 1 is a kind of lock structure schematic diagram of the utility model;

Fig. 2 is the mounting structure schematic diagram of Fig. 1;

Fig. 3 is the use schematic diagram of lockset shown in Figure 1, describes the lockset open mode;

The use schematic diagram of lockset shown in Fig. 4 bitmap 1 is described the lockset locking state.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

A kind of glass door lock as shown in Figure 1, 2, it comprises positive limit lock housing 1, the secondary lock housing 2 that is fixedly mounted on respectively on the glass door two fan doors, its both is the inner-cavity structure of hexahedron structure, and its two medial surface is a lateral opening of close glass door just, its the two relative face is provided with and all offers through hole, and the two through hole of offering correspondence that is complementary; In the inner chamber of positive limit lock housing 1 contiguous block 14 that horizontally slips along lower limb on its inner chamber is installed, in the side of contiguous block 14 near secondary lock housing 2, the fixing lock 16 that is equipped with, lock 16 can pass the through hole that is provided with on positive limit lock housing 1 and secondary lock housing 2 opposite faces, lock 16 passes through hole, positive limit lock housing 1 and secondary lock housing 2 are locked together, realize the locking of glass door.

In order to make said structure and to open by its locking of key operated realization, lateral surface in positive limit lock housing 1 is equipped with the tapered end 11 that can supply key to insert, after key inserts tapered end 11, but control lock 11 is rotated with respect to positive limit lock housing 1, and rotation amplitude is the 0-180 degree, and the medial end of tapered end 11 stretches into the inner chamber of positive limit lock housing 1; The medial end that stretches into positive limit lock housing 1 at tapered end 11 is provided with shifting block 12, and shifting block 12 is fixed by jump ring 13 and is installed in the medial end of tapered end 11; The other end of shifting block 12 is provided with pivot dress hole, on contiguous block 14, adorn the slotted hole 141 that extends up and down of offering of hole coupling with shifting block 12 pivots, contiguous block 14 and shifting block 12 by rivet 15 with it the two connect into can be according to the hinge arrangement of rivet 15 rotational, and rivet 15 can be according to the length direction of slotted hole 141 along slip slotted hole 141 in.In order to insert key turns tapered end 11, to drive the slip of contiguous block 14, the turning cylinder of the turning cylinder of tapered end 11 and rivet 15 is parallel to each other, and its two turning cylinder distance that staggers mutually, thereby forms a linkage of being made up of tapered end 11, shifting block 12, rivet 15, contiguous block 14.

Shown in Fig. 3,4, above-mentioned lockset is inserted and rotated 180 degree with key in use, makes tapered end 11 rotate, and drive shifting block 12 rotates 180 degree, according to mechanical general knowledge and known technology theory, because this place is a linkage, piece 14 slip in positive limit lock housing 1 that is dynamically connected of the rotating band of shifting block 12, thereby driving lock 16 stretches out, and insert secondary lock housing 2, realize the locking of lockset

In order to avoid above-mentioned shifting block 12 unnecessary rotation under action of gravity, to occur, in positive lock housing 1 inside, limit one spring 17 is set, one end of spring 17 is connected on the rivet 15, the other end is connected on the contiguous block 14, when lockset portion is in non-working condition, spring is upwards strained rivet 15, is unlikely to slide into because gravity does in the below of slotted hole 141 with control shifting block 12 and rivet 15; Simultaneously, also can be when lockset lock, tension rivet 15, thus rivet 15 can not glide, and guarantees the stable locking of lockset.

In addition, as shown in Figure 2,, also be provided with the lining 18 that tapered end 11 is fixed on lock housing 1 inside, positive limit in the outboard end of tapered end 11.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
