Description

A kind of fixed password lock

Technical field

The utility model relates to the coded lock technology field, relates in particular to a kind of fixed password lock.

Background technology

The fixed password of prior art is locked and is provided with snap close screens and latch hook; Also being provided with the leading section that forces latch hook in the housing of fixed password lock reaches latch hook spring in the snap close screens, is used for the lock core of latch hook locking and is used to untie the turntable structure of lock core; When latch hook was protruding, the leading section of latch hook was with the closure of openings of snap close screens, and lock core locks latch hook; Rotating disk on turntable structure does not forward correct lockset position of coupler to; When perhaps not having effective key to open lock core, latch hook can't be return, and latch hook and snap close screens form an effective snap close.

Rotating disk on turntable structure forwards correct lockset position of coupler to; When perhaps utilizing effective key to open lock core, latch hook does not receive the obstruction of lock core, and latch hook is released; Promote the push button on the housing this moment, push button drives the leading section of latch hook and returns in the housing of fixed password lock.But the motion of push button is a rectilinear motion, and push button is to promote along the direction of motion of latch hook; The useful effect power of promotion push button and the spring force of latch hook spring are on same straight line; Thrust must could be return the leading section of latch hook in the housing greater than the spring force of latch hook spring, and the spring force of latch hook spring is often bigger, therefore; Extremely require great effort when promoting, when unblanking, make troubles for the user through the push button straight line.

Summary of the invention

The purpose of the utility model is to the deficiency of prior art a kind of fixed password lock to be provided; Through cooperating of inclined-plane between button and the push rod; Original horizontal promotion is become vertical promotion; Press button realization latch hook and return in the housing, the coded lock of this structure more meets the body mechanics, and the user is more laborsaving when unblanking.

For realizing above-mentioned purpose, a kind of fixed password lock of the utility model comprises housing; Be provided with latch hook in the said housing; Offer the snap close screens on the said housing, the leading section of said latch hook passes said snap close screens, and butt has the latch hook spring between said enclosure interior and the said latch hook; Being provided with one in the said housing is used for the leading section of latch hook is pushed back the latch hook resetting means in the housing; Said latch hook resetting means comprises button and push rod, and said button and push rod all are mounted slidably in said enclosure interior, and said push rod is connected between said latch hook and the button.

As preferably, the quantity of said latch hook is two, and two latch hooks stack up and down, the push rod frontal plane butt of the latch hook back plane of said latch hook and said push rod, the button front bevel butt of the push rod back bevel of said push rod and said button.

As preferably, said housing comprises upper casing, cover plate and base plate, and said cover plate and base plate are bolted in said upper casing bottom successively; Said button is arranged between said upper casing and the cover plate, and said upper casing and said button junction are provided with boss, and said button is provided with the gathering sill that matches with said boss.

As preferably, the upper end of said cover plate is provided with and is used to limit the positive stop lug boss that said button ejects.

As preferably, the lower end of said upper casing is provided with and is used to limit the limited block that said push rod slides along fixed-direction.

The beneficial effect of the utility model: a kind of fixed password lock of the utility model; Comprise housing, be provided with latch hook in the said housing, offer the snap close screens on the said housing; The leading section of said latch hook passes said snap close screens; Butt has the latch hook spring between said enclosure interior and the said latch hook, is provided with one in the said housing and is used for the leading section of latch hook is pushed back the latch hook resetting means in the housing, and said latch hook resetting means comprises button and push rod; Said button and push rod all are mounted slidably in said enclosure interior, and said push rod is connected between said latch hook and the button; This fixed password lock through cooperating of inclined-plane between button and the push rod, becomes original horizontal promotion into vertical promotion, presses button and realizes that latch hook returns in the housing, and the coded lock of this structure more meets the body mechanics, and the user is more laborsaving when unblanking.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is carried out detailed description.

To shown in Figure 6, a kind of fixed password lock of the utility model comprises housing 1 like Fig. 1; Be provided with latch hook 2 in the said housing 1; Offer snap close screens 3 on the said housing 1, the leading section 22 of said latch hook 2 passes said snap close screens 3, and butt has latch hook spring 4 between said housing 1 inside and the said latch hook 2; Being provided with one in the said housing 1 is used for the leading section 22 of latch hook 2 is pushed back the latch hook resetting means 5 in the housing 1; Said latch hook resetting means 5 comprises button 51 and push rod 52, and said button 51 all is mounted slidably in said housing 1 inside with push rod 52, and said push rod 52 is connected between said latch hook 2 and the button 51.

The quantity of said latch hook 2 is two, and two latch hooks 2 stack up and down, the latch hook back plane 21 of said latch hook 2 and push rod frontal plane 521 butts of said push rod 52, the push rod back bevel 522 of said push rod 52 and button front bevel 511 butts of said button 51.

Said housing 1 comprises upper casing 11, cover plate 12 and base plate 13, and said cover plate 12 is bolted in said upper casing 11 bottoms successively with base plate 13; Said button 51 is arranged between said upper casing 11 and the cover plate 12, and said upper casing 11 is provided with boss 111 with said button 51 junctions, and said button 51 is provided with the gathering sill 512 that matches with said boss 111.

The upper end of said cover plate 12 is provided with and is used to limit the positive stop lug boss 121 that said button 51 ejects.

The lower end of said upper casing 11 is provided with and is used to limit the limited block 112 that said push rod 52 slides along fixed-direction.

When the user need unblank, only need press the button 51, to inner slide, the thrust of button front bevel 511 is in push rod back bevel 522 in upper casing 11 for button 51, and thrust becomes longitudinal thrust by original lateral thrust, realizes the conversion of thrust direction.Push rod 52 can only longitudinally slide under the effect of the limited block 112 that slides.The thrust of push rod frontal plane 521 is in latch hook back plane 21, and realization latch hook 2 is return in the housing 1.At this moment, latch hook spring 4 is by pretension, and snap close screens 3 is opened.When user's release button 51, latch hook spring 4 resets, and latch hook 2 cuts out snap close screens 3.

This fixed password lock; Through cooperating of inclined-plane between button 51 and the push rod 52, original horizontal promotion is become vertical promotion, press button 51 and realize that latch hooks 2 return in the housing 1; The coded lock of this structure more meets the body mechanics, and the user is more laborsaving when unblanking.The coded lock of this structure more meets the body mechanics, and the user is more laborsaving when unblanking.

Above content is merely the preferred embodiment of the utility model; For those of ordinary skill in the art; According to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, this description should not be construed as the restriction to the utility model.
