The large square tongue component comprises a large square tongue. The oblique tongue component comprises an oblique tongue, an oblique tongue pulling rod fixedly connected on the oblique tongue, and an oblique tongue sliding block arranged on the oblique tongue pulling rod. The rotating body component comprises a rotating body, an oblique tongue stirring piece arranged on the rotating body, and an oblique tongue pushing plate which is arranged on the large square tongue. An elastic part is arranged at the top of the oblique tongue pushing plate. A transmission structure from the mechanical lock head to the oblique tongue is simple, a long stirring piece is of no need, deforming or breaking cannot happen easily during using, and the service life of the door lock cannot be affected.

Description

A kind of emergency opening structure of door lock

Technical field

The utility model relates to a kind of emergency opening structure of door lock.

Background technology

In current door lock industry, intelligent door lock industry especially, by comprising mechanical lock head, with mechanical lock head, as standby emergent unlocking approach, while using mechanical lock head to unblank, mechanical lock head is by after generous gyrus lingulais contracting, also need by latch bolt retraction, to complete complete unlocking action.In existing door lock, transmission from mechanical tapered end to latch bolt generally adopts long plectrum to carry out transmission, its drive mechanism more complicated, under this structure, because the intensity of long plectrum is limited, if forced rotating mechanical lock head in the situation that transmission has some setbacks, can cause component distortion or fracture, thereby affect life-span and the stability of door lock.

Summary of the invention

For above-mentioned technological deficiency, the utility model proposes a kind of emergency opening structure of door lock.

In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:

A kind of emergency opening structure of door lock, comprise mechanical lock head, generous tongue assembly, turn assembly and latch bolt assembly, described generous tongue assembly comprises generous tongue, described latch bolt assembly comprises latch bolt, is fixedly connected on the latch bolt pull bar in described latch bolt and is arranged on the latch bolt slide block on described latch bolt pull bar, the described assembly of turning comprises turns, and is located at the latch bolt plectrum on turning, and also comprises latch bolt push pedal, described latch bolt push pedal is located on described generous tongue, and the top of described latch bolt push pedal is provided with elastomeric element.

Further, described latch bolt push pedal is provided with a groove, and described generous tongue is provided with banking pin, and described banking pin is located in this groove, and described latch bolt push rod can carry out limited movement along described groove.

Further, described latch bolt plectrum contacts with described latch bolt slide block, and when generous tongue retraction, one end of described latch bolt push pedal contacts with the other end of described latch bolt plectrum, and the opposite side of described latch bolt push pedal contacts with described mechanical lock head.

Further, described elastomeric element is spring, and one end of described spring is arranged on the top of described latch bolt push pedal, and the other end of described spring is arranged on described generous tongue.

The beneficial effects of the utility model are: in door lock of the present utility model, by the rotation of mechanical lock head, make generous gyrus lingulais contracting, when generous tongue is completely in lock box, lower end and the mechanical lock head of latch bolt push rod contact, rotary machine tapered end, and mechanical lock head drives latch bolt push rod to move up, thereby promoting latch bolt plectrum rotates, latch bolt plectrum drives latch bolt slide block to move, thereby can realize latch bolt retraction, under the effect of the elastomeric element of latch bolt push rod, latch bolt recovery rod, latch bolt is stretched out.The drive mechanism of the utility model from mechanical lock head to latch bolt is more succinct, has avoided using long plectrum, is in use not easy distortion or fracture, can not affect the life-span of door lock.

Accompanying drawing explanation

Fig. 1 is structure chart of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1, a kind of emergency opening structure of door lock, comprise mechanical lock head 5, generous tongue assembly, turn assembly and latch bolt assembly, described generous tongue assembly comprises generous tongue 4, described latch bolt assembly comprises latch bolt 2, be fixedly connected on the latch bolt pull bar 8 in described latch bolt 2 and be arranged on the latch bolt slide block 7 on described latch bolt pull bar, the described assembly of turning comprises turns 10, and be located at the latch bolt plectrum 9 on turning, also comprise latch bolt push pedal 11, described latch bolt push pedal 11 is located on described generous tongue 4, the top of described latch bolt push pedal 11 is provided with elastomeric element 3, this elastomeric element can be spring 3, one end of described spring 3 is arranged on the top of described latch bolt push pedal 11, the other end of described spring 3 is arranged on described generous tongue 4, the effect of this spring 3 is to utilize the pulling force of spring 3 to realize the effect of return latch bolt push pedal 11, in actual use, can adopt all elastomeric elements that can realize this function, for example spring one end is located to the bottom of latch bolt push pedal 11, the other end is located on generous tongue 4, utilize the thrust of spring to realize, described latch bolt push pedal 11 is provided with a groove, described generous tongue is provided with banking pin 12, described banking pin 12 is located in this groove, described latch bolt push rod 11 can carry out limited movement along described groove, in the present embodiment, be provided with 2 same grooves and 2 banking pins, described banking pin is located at respectively separately in groove, banking pin is also fixed on generous tongue 4.Described latch bolt plectrum 9 contacts with described latch bolt slide block 10, and when generous tongue 4 retraction, one end of described latch bolt push pedal 11 contacts with the other end of described latch bolt plectrum 9, and the opposite side of described latch bolt push pedal 11 contacts with described mechanical lock head 5.

During work, rotary machine tapered end 5, contact 14 drive side's tongue driving levers 13 of mechanical lock head, the party's tongue driving lever 13 drives generous tongue 4 retractions, after generous tongue 4 bounces back completely, latch bolt push rod 11 can mechanical lock head contact 14 contacts, rotary machine tapered end 5 again now, the contact 14 of mechanical lock head drives latch bolt push rod 14 to move up, under the effect at banking pin 12 and groove, latch bolt push rod 14 is done limited movement, latch bolt push rod 14 drives one end of latch bolt plectrum 9 to rotate, thereby 9 interlocks of latch bolt plectrum are turned, 10 drive latch bolt slide blocks 7 slide backward, thereby drive latch bolt retraction, decontrol mechanical lock head 5, latch bolt push rod 14 is return under the effect of spring, under the effect at banking pin 12 and groove, latch bolt push rod 14 is done limited movement, at latch bolt pull bar 8, be arranged with the 3rd spring 6, under the effect of the 3rd spring 6, thereby latch bolt plectrum 9 is return also, latch bolt slide block 10 is being set in the 4th spring of latch bolt pull bar 8, and the first spring 1 that is set in latch bolt pull bar 8 acts on lower return, thereby latch bolt 2 is stretched out.

The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
