Description

TECHNICAL FIELD

[0001] The utility model relates to a car door limiter technical field especially convenient to disassemble's car door limiter. BACKGROUND

[0002] Car door limiter is an important part of car door. It is used for limiting the opening angle of car door. Car door limiter is mainly composed of fixed frame (fixed with car body), rotating shaft (rotary connection with fixed frame) and limiting arm (one end is fixed with car door and one end is fixed with rotating shaft). Every time when opening and closing car door, the rotating shaft of car door limiter will rotate, and the rotating shaft will be abraded and produce abnormal sound after being used for many times, so the rotating shaft needs to be replaced. However, the rotating shaft of the prior art is directly welded with the limiting arm, so that the rotating shaft and the limiting arm need to be replaced together when being replaced, causing waste of resources. Therefore, in view of the above status, it is urgent to develop a convenient-to-disassemble car door limiter which is convenient to disassemble and replace and saves materials, so as to overcome the defects in the prior art and meet the current demand. SUMMARY

[0003] The utility model discloses a kind of convenient-to-disassemble car door limiters, to solve the problems raised in the above background art.

[0004] In order to achieve the above object, the utility model adopts the following technical scheme:

[0005] A kind of convenient-to-disassemble car door limiter, including base, rotating shaft, shaft sleeve and limiting arm, the quantity of the base is two, every base is provided with two first installation holes for bolt passing, the upper and lower sides of the rotating shaft are detachably fixed with one shaft sleeve, the shaft sleeve is rotatably connected with base, the rotating shaft is fixedly connected with limiting arm, the limiting arm is provided with two second installation holes for bolt passing.

[0006] Preferably, the shaft sleeve is made of bearing steel.

[0007] Preferably, the end of the shaft sleeve is fixed with a knob.

[0008] Preferably, the upper and lower ends of the rotating shaft are provided with external threads, and the shaft sleeve is provided with internal threads matched with the external threads.

[0009] The utility model has the advantages that the shaft sleeve is abraded by friction with the base after rotating for many times, and abnormal sound is likely to occur after abrasion, so it needs to be disassembled and replaced. When replacing, the base is first disassembled, then the shaft sleeve is unscrewed from the rotating shaft by turning the knob with hand, and the new shaft sleeve is installed on the rotating shaft. In summary, the utility model is convenient to disassemble and replace, and saves materials. BRIEF DESCRIPTION OF DRAWINGS

[0015] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0016] The specific embodiments are given below.

[0017] Referring to Figs. 1-3 In the embodiments of the utility model, a car door limiter convenient to disassemble comprises base 1, rotating shaft 2, shaft sleeve 3 and limiting arm 4, the number of base 1 is two, two first mounting holes 101 for bolt passing through are arranged on each base 1, base 1 is fixed with car frame through bolt, one shaft sleeve 3 is detachably fixed on the upper and lower sides of rotating shaft 2, shaft sleeve 3 is rotationally connected with base 1, shaft sleeve 3 is made of bearing steel, so that it has good wear resistance, limiting arm 4 is fixedly connected on rotating shaft 2, two second mounting holes 401 for bolt passing through are arranged on limiting arm 4, limiting arm 4 is fixed with car door through bolt, knob 302 is fixed on the end of shaft sleeve 3, and shaft sleeve 3 is twisted through knob 302, external thread 201 is arranged on the upper and lower ends of rotating shaft 2, and internal thread 301 matched with external thread 201 is arranged in shaft sleeve 3.

[0018] Working principle: the convenient disassembly of the automobile door stopper, use, the base 1 is fixed to the frame, the limiting arm 4 is fixed with the door, each time the door is opened, the door will drive the limiting arm 4 to move, the limiting arm 4 drives the rotating shaft 2 and the shaft sleeve 3 to rotate, because the length and the rotation angle of the limiting arm 4 are limited, so the opening angle of the door is limited, the door is prevented from being opened excessively, and the shaft sleeve 3 is rubbed and worn after multiple rotations, and the wear is prone to abnormal noise, needs to be disassembled and replaced, when replacing, first, the base 1 is disassembled, then, the shaft sleeve 3 is unscrewed from the rotating shaft 2 by rotating the knob 302 by hand, and then the new shaft sleeve 3 is installed on the rotating shaft 2.

[0019] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
