Description
Technical field
The utility model relates to the commercial car field of components, relates in particular to a kind of car door lock parts.
Background technology
The door lock quality of automobile is most important to guaranteeing driving safety, in Vehicle Driving Cycle, once car door lock is thrown off, security incident occurs very easily.Existing automobile door lock is a kind of spring-piece lock mostly.Its structure is different from general cylinder lock with the principle of unblanking, and cylinder lock is that each teeth key teeth groove correspondence two pellets, but each teeth key groove of spring-piece lock corresponding little shell fragment only.Shell fragment shape core is to make of all steel, and is larger than the core of general common lock, also is cylindrical.The length of shell fragment is just large with the diameter of core etc.Lock is as circular cylinder, and the thickness of annular only has several millimeters.Having two pairs in the lock body on the hollow back of ring is that four long recess are with the center of circle for being symmetrical arranged.The width of long recess and shell fragment are corresponding relations, and be slightly wider than shell fragment.The width that this is slightly wide, but be to make things convenient on the shell fragment bullet freely to enter in the long recess under the bullet.Behind the upper core of lock body suit, the square hole of shell fragment central authorities then forms keyhole.Key insertion shell fragment central authorities unblank in other words.Although the assurance that this class door lock can be to a certain degree reliability, when high vehicle speeds on uneven road surface, when jolting vibrations, still might cause door lock to get loose, so in order to guarantee driving safety, the secondary door lock of a kind of supplement character of needs.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lateral sliding door secondary lock assembly, and is simple in structure, operates reliably, and effectively guaranteed the safety of commercial car lateral sliding door.
The utility model is achieved in that a kind of lateral sliding door secondary lock assembly, comprise base plate, cam, camshaft, ratchet, slide block assembly, slide block return spring and zip fixed support, described zip fixed support is installed in the bottom of base plate, described cam is installed in the back side of base plate, described ratchet is installed in the front of base plate, links by a camshaft that passes base plate between cam and the ratchet; Described base plate front is installed with the ratchet postioning abutment that matches with ratchet, and the end near ratchet on the described camshaft is equipped with flexible restoring organ; Be installed with slide block holder and spring fixed seat on the back side of described base plate, described slide block assembly is arranged on the slide block holder, the slider head of slide block assembly matches with cam, described slide block return spring one end links to each other with the slide block assembly, and the slide block return spring other end links to each other with spring fixed seat.
Described flexible restoring organ is ratchet return torsion spring.
Described slide block holder is a cylindrical bump, is provided with the waist-hole type chute on the described slide block assembly, and described waist-hole type chute matches with cylindrical bump.
The utility model lateral sliding door secondary lock assembly cooperates locked to ratchet of realization by the slide block assembly with the cam of ratchet interlock and drag-line operation, utilize the release of return spring band movable slider assembly return, simple in structure, operate reliably, effectively guaranteed the safety of commercial car lateral sliding door.
Description of drawings
Fig. 1 is the utility model lateral sliding door secondary lock assembly structure schematic diagram.
Among the figure: 1 base plate, 2 cams, 3 camshafts, 4 ratchets, the spacing shelves of 5 ratchets, 6 ratchet return torsion springs, 7 slide block assemblies, 8 slide block holders, 9 slide block return springs, 10 spring fixed seats, 11 zip fixed supports.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of lateral sliding door secondary lock assembly, comprise base plate 1, cam 2, camshaft 3, ratchet 4, slide block assembly 7, slide block return spring 9 and zip fixed support 11, described zip fixed support 11 is installed in the bottom of base plate 1, described cam 2 is installed in the back side of base plate 1, described ratchet 4 is installed in the front of base plate 1, links by a camshaft 3 that passes base plate 1 between cam 2 and the ratchet 4; Described base plate 1 front is installed with the ratchet postioning abutment 5 that matches with ratchet 4, and the end near ratchet 4 on the described camshaft 3 is equipped with flexible restoring organ; Be installed with slide block holder 8 and spring fixed seat 10 on the back side of described base plate 1, described slide block assembly 7 is arranged on the slide block holder 8, the slider head of slide block assembly 7 matches with cam 2, described slide block return spring 9 one ends link to each other with slide block assembly 7, and slide block return spring 9 other ends link to each other with spring fixed seat 10.
In the present embodiment, described flexible restoring organ is ratchet return torsion spring 6.
The utility model can further describe into, described slide block holder 8 is a cylindrical bump, is provided with the waist-hole type chute on the described slide block assembly 7, described waist-hole type chute matches with cylindrical bump.
