Background technique

It is more and more to hold various exhibitions now, isolate the interim one by one exhibition position of realization by screen, and all connect by splicing between the screen, existing screen splicing speed is slow, and consumption is artificial, traces it to its cause, be because be used to shield the fastening lock construction complexity that connects usefulness, be difficult to reach easy to disassemble and assemble, and, make screen splicing back outward appearance ugly because the key hole position is restricted.

Summary of the invention

Therefore, the fastening lock that provides a kind of splicing screen simple in structure, that key hole can be provided with flexibly and dismounting is convenient to use is provided the purpose of this utility model.

The purpose of this utility model is to realize like this.

A kind ofly splice the fastening lock that screen is used, comprise lock core, dead bolt, key core and key core retainer plate, described dead bolt is laminar body, the dead bolt end is hook-shaped formation one latch hook, and dead bolt middle part one side stretches out a flank, and it is opposite that latch hook and flank lay respectively at its direction of extension of dead bolt both sides, the root of dead bolt is articulated in lock core one end, and dead bolt is at least two, and the flank of adjacent two dead bolts and latch hook position opposite also are provided with a resetting structure that dead bolt is resetted at the root of dead bolt;

The described lock core the other end passes the key core retainer plate, the lock core middle part body surface of corresponding key core retainer plate is provided with a shrinkage pool, described key core also is located in the key core retainer plate, but key core is vertical mutually with lock core position in the key core body, key core the inner can coincide and the locking lock core with the shrinkage pool on the lock core body surface, the key core outer end is provided with key hole, also is with a spring that lock core is resetted in the lock core end of passing the key core retainer plate.

Above-mentioned technology technological scheme also can be done following further perfect.

Described key core retainer plate can extend to the lock core two ends respectively, and end formation one can be wrapped up the tapered end of dead bolt root, and the other end forms the lock tail of a parcel spring.

Described tapered end end inner side surface is slope shape and flank is corresponding on one side.

Described lock core end diameter of passing the key core retainer plate is dwindled and is formed a step, and spring one end withstands on the step, and the spring the other end withstands on the lock tail interior edge face.

Described resetting structure is the copper card of a parcel dead bolt root, and one group of opposite side of copper card rides over the dead bolt outer side surface by the bearing pin that articulates dead bolt, and another group opposite side of copper card suppresses on the dead bolt side.

Described shrinkage pool is the taper shrinkage pool, and corresponding key core end is tapered.

By screw-thread fit, realize the rotation of key core between described key core and the key core retainer plate.

Described key hole is interior hexagon.

The utility model structural design advantages of simple, key hole can be provided with flexibly according to the mounting point of screen, and it is firm to lock, and the dismounting of screen is all very flexible, has realized the quick mounting and the dismounting of exhibition position, and style is varied, and is applied widely.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with Fig. 1 and Fig. 2, a kind ofly splice the fastening lock that screen is used, comprise the shaft-like lock core 1 that is embedded in the screen, dead bolt 2, cylindrical key core 3 and cylindrical key core retainer plate 4, described dead bolt 2 in the form of sheets, one side of dead bolt 2 stretches out a pointed flank 20, the end of dead bolt 2 is a latch hook 21, it is opposite that latch hook 21 and flank 20 lay respectively at its direction of extension of dead bolt 2 both sides, the outer end of described lock core 1 articulates four dead bolts 2, and the flank 20 of two adjacent dead bolts 2 and latch hook 21 position opposite also are provided with a bronze medal card 5 at the root of

dead bolt

2,5 one groups of opposite side 50 of copper card ride over dead bolt 2 outer side surfaces by the bearing pin 6 that articulates dead bolt 2, and copper card 5 another group opposite side 51 suppress on dead bolt 2 sides.

Described lock core 1 middle part body surface is provided with a taper shrinkage pool 10, key core retainer plate 4 is passed in the inner of lock core 1, described key core 3 axially is located in the key core retainer plate 4 along key core retainer plate 4, cooperate by screw thread 7 between key core 3 and the key core retainer plate 4, realize the rotation up and down of key core 3, key core 3 lower ends are tapered can to coincide and locking lock core 1 with the taper shrinkage pool 10 on the lock core 1 middle part body surface, and it is axially arranged with key hole 30 upper end edge of key core 3, and key hole 30 inwalls are interior hexagon.

The lock core 1 inner end reduced of passing key core retainer plate 4 forms a step 11, is with a Returnning spring (end illustrates among the figure) on the lock core 1 of reduced, and spring one end withstands on the step 11, and the spring the other end withstands in the screen.

During use, key core retainer plate 4 is embedded in the top margin of screen, key core 3 moves up and down at the screen top margin, dead bolt 2 stretches out the screen side, if down screw key core, the taper hole of key core lower end and lock core coincide, and forces lock core to move in screen, then the flank of the dead bolt section bar that is installed in the screen side presses, and latch hook is outwards strutted collude the section bar of tight another piece screen.

Unscrew key core, lock core moves outside screen under action of reset spring, and dead bolt resets under the pressure effect of copper card, and latch hook unclamps another piece screen.

Embodiment 2, and in conjunction with Fig. 3 and Fig. 4, example 2 difference from Example 1 are; The position that taper shrinkage pool 10 on the lock core is offered has rotated 90 degree, and the reason of She Zhiing is the side that key core retainer plate 4 can be embedded in screen like this, and key core can pass in and out in the screen side.
