Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of dead bolt fixed structure of the utility model preferred embodiment, comprise lock body 1, described lock body 1 comprises liner plate 2, latch bolt assembly 3, plectrum 4 and Inclined bolt direction changing assembly 5, latch bolt assembly 3 comprises latch bolt 31, first spring 32, pull bar 33, pad 34 and location-plate 35, latch bolt 31 is fixedly connected with one end of pull bar 33, pull bar 33 is through liner plate 2, latch bolt 31 is placed in outside liner plate 2, it is outside that first spring 32 is set in pull bar 33, the other end of pull bar 33 is successively through pad 34 and location-plate 35, and be fixedly connected with location-plate 35, the end of plectrum 4 is between pad 34 and location-plate 35, Inclined bolt direction changing assembly 5 is connected between the end of plectrum 4 and pad 34 pluggablely.
Inclined bolt direction changing assembly 5 can have various structures mode, in the present embodiment, Inclined bolt direction changing assembly 5 comprises commutation block 51, second spring 52 and lead 53, second spring 52 is set in the outside of lead 53, one end of commutation block 51 is connected with lead, and its other end is connected between the end of plectrum 4 and pad 34 pluggablely.When the block 51 that commutates inserts between the end of plectrum 4 and pad 34, latch bolt 31 part is stuck in the inside of liner plate 2; When commutation block 51 is from when transfering between the end and pad 34 of plectrum 4, under the effect of the first spring 32, latch bolt 31 is ejected liner plate 2 by pull bar 33, and now rotatable latch bolt 31 is to realize commutation.In the present embodiment, in order to make the structure rationalization of lock body, namely the side that plectrum 4 is positioned at pull bar 33 is positioned at the side near lock body inside, and namely the opposite side that Inclined bolt direction changing assembly 5 is positioned at pull bar 33 is positioned at the side of the lower cover 6 of lock body.
The lower cover 6 of lock body 1 is provided with the through hole 61 passed for lead 53, commutation block 51 is located at the inner side of the lower cover 6 of lock body 1, second spring 52 is located between commutation block 51 and through hole 61, lead 53 telescopically, through through hole 61, drives steering block 51 to be connected between the end of plectrum 4 and pad 34 pluggablely in the telescopic process of lead 53.
In the present embodiment, commutation block 51 comprises plectrum positioning boss 511 and shifting block 512, and one end of plectrum positioning boss 511 is connected with lead 53, and its other end is connected between the end of plectrum 4 and pad 34 pluggablely; Lock panel 7 is provided with chute 71, the outside of commutation block 51 is provided with the shifting block 512 matched with chute 71, shifting block 512 is installed in chute 71, stir from the outside of lock panel 7 shifting block 512 can make commutation block 51 can along the slip of chute 71, the length of chute 71 is the distance that commutation block 51 slides, and the plectrum positioning boss 511 that thus limit commutation block inserts the degree of depth in the space between plectrum 4 and pad 34.
Guide strip 8 is also provided with between pad 34 and location-plate 35, the end of plectrum 4 is located between guide strip 8 and location-plate 35, the effect of guiding is played in the motion of this guide strip 8 pairs of pull bars 33, and the plectrum positioning boss 511 of commutation block 51 is connected between the end of plectrum 4 and guide strip 8 pluggablely.Preferably, guide strip 8 is U-shaped, and pull bar 33 is stuck in its opening part.The medial surface of plectrum positioning boss 511 is the cambered surface of indent, with the ends match of the plectrum 4 of columniform pull bar 33 and arc.Wherein, plectrum 4 comprises interior plectrum 41 and outer plectrum 42, and outer plectrum 42 is positioned at the top of pull bar 33, and interior plectrum 41 is positioned at the below of pull bar 33.Correspondingly, plectrum positioning boss 511 is set to two of the upper and lower sides laying respectively at pull bar, and when plectrum positioning boss 511 inserts between plectrum 4 and guide strip 8, pull bar 33 passes between two plectrum positioning boss 511.
In latch bolt 31 commutation process, first, as shown in Figure 3, latch bolt 31 is under non-ejection state, and latch bolt 31 part is stuck in liner plate 2, and location-plate 35 is under the effect of the first spring 32, be close to the sidewall of the commutation sidewall of block 51 and interior plectrum 41, outer plectrum 42, commutation block 51 is subject to the effect of the second spring 52, is adjacent to the locating surface of chute 71 all the time, prevents commutation block 51 from moving backward, as shown in Figure 4, latch bolt 31 is under ejection state, the shifting block 512 at commutation block 51 top is stirred with hand, commutation block 51 is moved along chute 71 direction, make it to compress the second spring 52 simultaneously, plectrum positioning boss 511 is extracted between guide strip 8 and plectrum 4, now, owing to commutating, the sidewall of block 51 and location-plate 35 disengage, therefore pull bar location-plate 35 can continue to move forward under the effect of the first spring 32, the distance of its movement is the distance of an Inclined bolt direction changing block plectrum positioning boss 511, this distance can make latch bolt 31 eject completely outside liner plate 2, as shown in Figure 4.Then, as shown in Figure 5 and Figure 6, under latch bolt 31 commutation states, pull bar location-plate 35 is under the effect of the first spring 32, blocked by pull bar guide strip 8 location after interior plectrum 41 and outer plectrum 42 are rotated an angle, thus can not continue to move forward, now, latch bolt 31 ejects outside liner plate 2 completely, manual rotation latch bolt 31 to 180 ° can realize commutation.Finally, as shown in Figure 7, under latch bolt 31 commutates successful state, latch bolt 31 completes changes rotate backward interior plectrum 41 and outer plectrum 42, after making the distance of pull bar location-plate 35 movement backward be greater than commutation block 51 sidewall, this commutation block 51, can by commutation block 51 driven forward under the effect of the first spring 32, thus again block pull bar location-plate 35, make latch bolt 31 be unlikely to eject outside liner plate 2.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
