Abstract
The utility model discloses a kind of U-shaped pull bar, comprise two U-shaped, two U-shaped by two bolt parts, intermediate pipe is connected, between two U-shaped, be provided with annular extension spring, the bottom of described U-shaped is provided with spring suspension part, on described spring suspension part, be provided with the suppending hole that hangs annular extension spring, on described bolt part, be provided with screw thread, described intermediate pipe by nut with described in be threaded, the two ends of described annular extension spring are hooked on respectively in the suppending hole of described spring suspension part and are sheathed on described two bolt parts and intermediate pipe.Because the utility model is being provided with the annular extension spring being sheathed on two bolts and intermediate pipe between two U-shaped, stressed when excessive when U-shaped pull bar, the function of overload protection has been played in annular extension spring, makes the work that U-shaped pull bar can be more stable.
Description
Technical field
The utility model relates to a kind of U-shaped pull bar, relates in particular to a kind of U-shaped pull bar with overload protection function.
Background technology
Rod assembly is a part for automotive steering structure, it is for driving wheel steering, at present, rod head of the prior art, be the rod head of being cast by cast iron, be in use easy to be pulled off, after rod head is pulled off, whole driving system will be worked, and easily causes the generation of automobile safety accident.
Utility model content
The utility model provides a kind of U-shaped pull bar, to solve rod head of the prior art, be the rod head of being cast by cast iron, be in use easy to be pulled off, after rod head is pulled off, whole driving system will be worked, the problem that easily causes automobile safety accident to occur.
For solving above technical matters, the technical solution of the utility model is for providing a kind of U-shaped pull bar.
A kind of U-shaped pull bar, comprise two U-shaped, two U-shaped by two bolt parts, intermediate pipe is connected, and is provided with annular extension spring between two U-shaped, and the bottom of described U-shaped is provided with spring suspension part, on described spring suspension part, be provided with the suppending hole that hangs annular extension spring, on described bolt part, be provided with screw thread, described intermediate pipe by nut with described in be threaded, the two ends of described annular extension spring are hooked on respectively in the suppending hole of described spring suspension part and are sheathed on described two bolt parts and intermediate pipe.
Because the utility model is being provided with the annular extension spring being sheathed on two bolts and intermediate pipe between two U-shaped, stressed when excessive when U-shaped pull bar, the function of overload protection has been played in annular extension spring, makes the work that U-shaped pull bar can be more stable.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model connecting rod and annual spring;
Fig. 2 is that the utility model annual spring is mounted to bar linkage structure schematic diagram.
The specific embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with accompanying drawing, the present utility model is further illustrated.
As shown in Figure 1, a kind of U-shaped pull bar of the present utility model comprises two U-shaped 2, two U-shaped 2 by two bolt parts 1, intermediate pipe 9 is connected, between two U-shaped 2, be provided with annular extension spring 6, on U-shaped 2, be provided with mounting hole 3, the bottom of two U-shaped is provided with spring suspension part 5, spring suspension part 5 is one to be welded on square in U-shaped 2, on spring suspension part 5, be provided with suppending hole 4, the two ends of annular extension spring 6 connect respectively in the suppending hole 4 of two U-shaped 2, in U-shaped 2, be arranged with bolt part 1, on bolt part 1, be provided with screw thread 7, screw thread 7 is connected with intermediate pipe 9 by nut 8, intermediate pipe 9 two ends are provided with nut 8, annular extension spring 6 is hooked on respectively in the suppending hole 4 of two spring suspension parts 5 and is sheathed on two bolt parts 1 and intermediate pipe 9, owing to being provided with the annular extension spring 6 being sheathed on two bolts 1 and intermediate pipe 9 between two U-shaped 2, when U-shaped pull bar stressed when excessive, the function of overload protection has been played in annular extension spring 6, make the work that U-shaped pull bar can be more stable.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: the technical scheme that its in specification sheets still can be recorded aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement, and these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
