Abstract
The utility model discloses a kind of door latch structure of car door, and automobile door lock construction is connected by lock core and rotary body and forms.The surface, portion of exposing of lock core is provided with external screw thread and the portion of exposing is provided with the first hole, rotary body is provided with internal thread towards the docking section of lock core, and docking section is provided with the second hole, rotary body and lock core are spirally connected and are assembled to the first hole and the second hole and overlap, and in holes, grafting is provided with pin rod axial location lock core and rotary body.Newly-designed automobile door lock construction can optimize the door latch structure of car door, and in assembling process, low cost realizes the axial restraint of lock core and rotary body, simplifies assembly technology, reduces production cost and assembly difficulty.
Description
Technical field
The utility model relates to a kind of door latch structure, particularly relates to a kind of door latch structure of motor vehicle automobile door.
Background technology
Traditional automobile door lock construction carries out plane positioning by the cross-shaped on lock core and rotary body, and carrys out axial restraint by ring and rubber blanket.But when this design is assembled in process of production, difficulty is comparatively large, and product durability can not be guaranteed, and low cost can not realize axial restraint.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the door latch structure proposing a kind of car door, solves door latch structure assembling challenge.
The purpose of this utility model, to be achieved by the following technical programs: a kind of door latch structure of car door, connected by lock core and rotary body and form, the surface, portion of exposing of wherein said lock core is provided with external screw thread and the portion of exposing is provided with the first hole, described rotary body is provided with internal thread towards the docking section of lock core, and docking section is provided with the second hole, described rotary body and lock core are spirally connected and are assembled to the first hole and the second hole and overlap, and in holes, grafting is provided with pin rod axial location lock core and rotary body.
Further, described first hole and the second hole are radial through pass structure, and pin rod is connected in holes and pin rod two ends are limited in surface, docking section.
Further, described first hole is the closed type structure of the certain radial depth of tool, and described second hole is radial through pass structure, and pin rod is connected to that in holes and pin rod one end is touched bottom the first hole, the other end is limited in surface, docking section.
Remarkable result after technical solutions of the utility model application implementation is: lock core and rotary body by Screw assembly, and then are fixed with pin, low cost can realize lock core and rotary body axial restraint, simplify assembly technology.
Accompanying drawing explanation
Fig. 1 is schematic diagram before the assembling of the utility model car door door lock new construction.
Fig. 2 is schematic diagram after the assembling of the utility model car door door lock new construction.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Under normal circumstances, the door latch structure of car door, is connected by lock core 1 and rotary body 2 and forms.And both package assemblies, be easy to assembling under the condition of the axial strong fix of demand fulfillment and cost is lower.
Embodiment 1, the utility model preferred embodiment schematic diagram as shown in Figure 1, the surface of wherein lock core exposing portion 11 is provided with external screw thread 111, and expose portion 11 and be provided with radial the first through hole 112, rotary body 2 is provided with internal thread 211 towards the docking section 21 of lock core, and docking section is provided with the second hole 212.Based on the design's structure, when lock core and rotary body assemble, make lock core be screwed onto together with rotary body screw thread, and stop spinning when the first hole that lock core and rotary body are screwed in the portion of exposing overlaps with the second hole on docking section, and then fix with pin rod 3.It should be noted that, when pin rod 3 is connected in holes, the two ends of pin rod should keep exposing, otherwise easily cause by the action of interference effect rotary body normal open and close lock in the process of unblanking, and the door lock assembled as shown in Figure 2.
Embodiment 2, in addition to the implementation, this creation also has many optional embodiments.For example, exposing the first hole set by portion is the closed type structure with certain radial depth, second hole set by docking section is radial through pass structure, in both assembling processes, when the first hole that lock core and rotary body are screwed in the portion of exposing overlaps with the second hole on docking section, pin rod is connected in holes, the bottom in the first hole is touched in one end of pin rod, the other end is limited in the surface of lock core docking section, pin rod can be made like this in assembling process to be positioned at the first hole and being spirally connected of the second hole is located, axial restraint can be carried out well to the place of being spirally connected in the first hole and the second hole, the assembling of pin rod can be made again simpler.
Can be found out by above-mentioned character express, apply the door latch structure of car door of the present utility model, can optimize the door latch structure of car door, in assembling process, low cost realizes the axial restraint of lock core and rotary body, simplify assembly technology, reduce production cost and assembly difficulty.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
