Abstract

The utility model discloses a pressing lock, and provides a pressing lock of which the size is reduced, so that the lock can be suitable to be used in a small space under the condition that the function of the lock is guaranteed. A tapered head matched with a key is arranged at the upper end of a lock cylinder; the lock cylinder and a lock shaft are arranged in a lock body; the lock cylinder is sleeved outside the lock shaft; a spiral slot and a locking slot are formed on the lock cylinder; a driving pin passes through the spiral slot and penetrates through the lock shaft; the lock shaft and the lock body are guided and limited through a limiting pin; an axial limiting slot and a radial limiting slot are formed on the lock body; when the lock is unlocked, the limiting pin is positioned in the radial limiting slot; when the lock is locked, the limiting pin is positioned in the axial limiting slot; and the lower end of the lock shaft is fixedly connected with a spring bolt. The structure of the whole pressing lock is that the standard height GH is up to 18 millimeters by updating an inner driving structure, so that the pressing lock can meet the demand for use in the small space; the whole pressing lock has a simple and stable structure; the protection level of the lock is guaranteed; and high earthquake resistance is realized.

Description

Compress lock

Technical field

The utility model relates to a kind of lockset, in particular, relates to a kind of lock that compresses with cramped construction.

Background technology

Industries such as the communication that can relate at present, electronics, wind-powered electricity generation, railway traffic, air-conditioning equipment; Requirements of type selecting to lockset is very strict; Because relate to the normal use of inner components and parts, guarantee its safety, stability, require the overall structure of product more reasonable naturally.Along with the development of modern industry lockset, scale constantly enlarges, and outdoor a series of attached component product requirement is also improved accordingly.Under the prerequisite that guarantees the normal operation of inner components and parts, also to consider its application life.Under the applied environment of constantly bringing forth new ideas, leave the also constantly compression of space of lockset for, the prototype lock takes up room big, is difficult to satisfy customer requirement.

The utility model content

The utility model is in order to overcome weak point of the prior art, provides a kind of under the situation that guarantees the lockset function, and the size of dwindling lockset is to adapt to the lock that compresses that little space uses.

The utility model is realized through following technical proposals:

A kind of lock that compresses is characterized in that, comprises lock body, lock core, lock shaft, dead bolt; Said lock core upper end is provided with the tapered end that cooperates with key, and said lock core and lock shaft are installed in the said lock body, and it is outside that said lock core is enclosed within said lock shaft; Said lock core is provided with helicla flute and lock groove, and said lock groove is positioned at said helicla flute top and is communicated with said helicla flute, and drive pin passes said helicla flute and said lock shaft; Spacer pin passes said lock shaft, and said lock shaft and said lock body are realized guiding with spacing through spacer pin, and said lock body is provided with the axial limiting groove of realization spacer pin continuous motion and stopper slot radially; Said axial limiting groove and radially stopper slot intersect; In the lockset opening, spacer pin is positioned at said radially stopper slot, at the lockset locking state; Said spacer pin is positioned at said axial limiting groove, and the lower end of said lock shaft is fixedly connected with said dead bolt; Between said lock body and the said lock core, be respectively arranged with sealing ring between said lock core and the lock shaft.

The height that exposes between said lock body and the dead bolt is in 5mm, and the lock body inside height is in 18mm.

The utlity model has following technique effect:

1, the lock that compresses of the utility model passes through the renewal to inner Drive Structure, and total is simple, stable, and the overall structure minimum can arrive the calibrated altitude of GH=18mm, thereby adapts to the needs that use in little space.

2, compressing in the lock of the utility model, sealing ring and lock body, lock core cooperatively interact and have guaranteed the degree of protection of lockset self, and have good shock resistance.

Fig. 2 compresses the sectional view of lock locking states for the utility model;

Fig. 3 compresses the sectional view of lock opening for the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.

The utility model compresses sketch map such as Fig. 1 of lock-shown in Figure 3, comprises lock body 9, lock core 2, lock shaft 6, dead bolt 12, and said lock core 2 upper ends are provided with the tapered end 1 that cooperates with key; Said lock core 2 is installed in the said lock body 9 with lock shaft 6, and said lock core 2 is enclosed within said lock shaft 6 outsides, and said lock core 2 is provided with helicla flute 3 and lock groove; Said lock groove is positioned at said helicla flute top and is communicated with said helicla flute, and drive pin 7 passes said helicla flute 3 and said lock shaft 6, and spacer pin 8 passes said lock shaft 6; Said lock shaft 6 is realized guiding and spacing with said lock body 9 through spacer pin 8; Said lock body 9 is provided with the axial limiting groove of realizing the spacer pin continuous motion and stopper slot radially, and axial limiting groove and radially stopper slot is crossing is in the lockset opening; Spacer pin 8 is positioned at said radially stopper slot; At the lockset locking state, said spacer pin 8 is positioned at said axial limiting groove, and the lower end of said lock shaft 6 is fixedly connected through screw 13 with said dead bolt 12.Be provided with sealing ring 5 between said lock body 9 and the said lock core 2, be provided with sealing ring 4 between said lock core 2 and the lock shaft 6.

Seal washer 10 and nut 11 are installed on the said lock body 9, are used for fixing with door-plate, door-plate perforate continuity company standard pass is realized exchanging fully.

The height h that exposes between said lock body and the dead bolt is in 5mm, and GH is in 18mm for the lock body inside height.

The utility model compresses the lock body of lock as exchanging structure, and lock core then can be changed according to customer requirement.Lock shaft also can replace to major axis according to customer requirement, thereby realizes the adjustable function of dead bolt and lock body inner distance value.

In the opening of lockset, drive pin is positioned at the spiral fluted bottom, and spacer pin is positioned at radially stopper slot.Key is inserted on the tapered end 1 of lock core, along with the rotation of key, lock core drives drive pin; Drive pin drives lock shaft; Lock shaft drives dead bolt, and drive pin is constant at the spiral fluted bottom position, and spacer pin radially rotates in the stopper slot at lock body; Lock core drives dead bolt and rotates 90 ° when 90 ° of key turns, and spacer pin is positioned at the radially junction of stopper slot and axial limiting groove.Key is rotated further, and drive pin rises along helicla flute, drives lock shaft and moves to the lock core direction; Spacer pin moves to the lock core direction in lock body axial limiting groove; When 180 ° of key turns, drive pin gets in the lock groove on helicla flute top, and dead bolt no longer rotates; Dead bolt realizes compressing locking axially to lock core direction motion certain distance.When unblanking, move opposite with the locking process, 90 ° of key opposite spins, dead bolt stretches out, and continues half-twist, dead bolt rotates 90 °, door is opened.
