Description

A kind of cable channel cover plate lock

Technical field

The utility model relates to a kind ofly anti-usurps lockset, relates to a kind of cable channel cover plate lock in particular.

Background technology

In current society, many metropolis are all with communication cable, and facilities such as high voltage cable, water supply pipe are embedded in underground, in order better above-mentioned facility to be safeguarded later on, usually.Whenever at a distance from a segment distance, a well head will be set, make it can maintain easily personnel's operation, be embedded in underground communication cable, stolen this hidden danger of facilities such as high voltage cable, water supply pipe but also exist.

At present; Also there is the people on the well head that is embedded with the appeal facility, well lid to be installed, and the anti-lock of usurping is installed at well lid, but owing to the surrounding enviroment of laying well lid all compare badly; Like rainwater, silt etc.; The core that causes possibly well lid is installed gets rusty, and is stopped up core or keyhole by silt, thereby causes well lid not open.

The utility model content

To the problems referred to above, the utility model technical problem to be solved is to provide a kind of simple in structure, can not cause not holding the cable channel cover plate lock of lock because of rainwater or silt.

To achieve these goals, the technical scheme of the utility model employing is:

A kind of cable channel cover plate lock comprises the lock shell that is provided with keyhole, is installed in the lock core in the lock shell through a fixed point; With the locking bolt that lock core matches, said lock core is processed by at least two lock core chips, and said each lock core chip is provided with a T-shaped T shape hole; One side of lock core chip is provided with the arc notch of a depression, and said arc notch is adjacent with the keyhole of lock shell, is provided with a shell fragment at the opposite side of lock core chip; On the lock shell near the shell fragment place, be provided with a shell fragment countercheck rod, the shell fragment countercheck rod blocks shell fragment, and said locking bolt is provided with a groove near a side of keyhole; Locking bolt near the lock core one side is provided with a protruded object, and protruded object inserts in the T shape hole of lock core chip, and the locking bolt another side is provided with a spring retention device; The spring retention device is provided with an aperture; Said aperture is provided with a guide peg, and a spring is installed on the guide peg, and insert in the lock shell at the two ends of guide peg.

Preferably, the radian of the arc notch of said each lock core chip is a radian inequality.

Preferably, on said each lock core chip in the two adjacent lock core chips down the upper surface of lock core chip be provided with the several projections thing.

Preferably, an end of said locking bolt is provided with a linkage, and a locking bar is installed on linkage.

Preferably, said lock core and locking bolt adopt stainless steel bars to process.

The beneficial effect of the utility model is: simple in structure, not fragile, all be separated with a segment distance between each lock core in the lock core mutually, and even if get rusty, do not hold with not leading lock core, in addition, the other silt of well lid has stopped up not lock core or keyhole.

The specific embodiment

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

To shown in Figure 6, a kind of cable channel cover plate lock comprises the lock shell 1 that is provided with keyhole 11 like Fig. 1; Be installed in the lock core 3 in the lock shell 1 through a fixed point 31, with the locking bolt 2 that lock core 3 matches, lock core 3 is processed by at least two lock core chips 32; Each lock core chip 32 is provided with a T-shaped T shape hole 322, and a side of lock core chip 32 is provided with the arc notch 324 of a depression, and arc notch 324 is adjacent with key 11 holes of lock shell 1; Opposite side at lock core chip 32 is provided with a shell fragment 321, on the lock shell 1 near shell fragment 321 places, is provided with a shell fragment countercheck rod 7, and shell fragment countercheck rod 7 blocks shell fragment 321; The elastic force of shell fragment 321 can be discharged, and act on the lock core chip 32, be provided with a groove 21 near a side of keyhole 1 at locking bolt 2; Locking bolt 2 near lock core 3 one sides is provided with a protruded object 22, and protruded object 22 inserts in the T shape hole 322 of lock core chip 32, and locking bolt 2 another sides are equipped with a spring retention device 5 with screw; Spring retention device 5 is provided with an aperture 51; Guide peg 4 passes aperture 51 and is fixed on the lock shell 1, and a spring 6 is installed on guide peg 35, should be noted that; Spring 6 should be installed on the guide peg 35 near the c end in T shape hole 322, and only in this way just can make the normality of lock is locking state.

The radian of the arc notch 324 of each lock core chip 32 is a radian inequality, could dispose various keys inequality like this, is the function that the utility model equipment reaches antitheft.

On each lock core chip 32 in the two adjacent lock core chips 322 down the upper surface of lock core chip be provided with several projections thing 323, it is too tight to prevent that two adjacent lock core chips from leaning on, and by iron rust or silt cause dumb, driven not lock.

One end of locking bolt 2 is installed a linkage 8 with screw, and a locking bar 9 is installed on linkage 8, and linkage 8 is dismountable with the connected mode of locking bar 9.

The normality of the utility model device becomes locking state; The protruded object 22 of locking bolt 2 is pressed in a end in T shape hole 322 through the elastic force of spring 6; Shell fragment 321 extruding lock core chips 32 then make the protruded object 22 of locking bolt 2 abut against the b end in T shape hole 322, cause locking state.

When opening the utility model device; Need open by the key of the band torsion of special outfit; Have only when the arc notch 324 of each lock core chip 32 in key and the lock core 3 matches; Could the protruded object 22 of locking bolt 2 be depressed into the c end in T shape hole 322 by key, thereby open the utility model equipment.

In addition,, when making lock core 3, can increase several lock core chips 32 more,, thereby increase the measure of precision of lock owing to the arc notch 324 in each lock core chip 32 has nothing in common with each other in order to increase the measure of precision of this lock.

Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; Can also make other distortion or improvement, these all belong to the protection domain of the utility model.
