Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber bracket for a rotating shaft. Background Art

[0002] Shock absorbers are a common device used to improve the comfort of cars. Generally, the car body rebounds the impact from the road through the shock-absorbing spring after absorbing the shock, accelerating the attenuation rate of the body vibration to achieve shock absorption of the car body and avoid damage. However, the spring itself has the ability to reciprocate, and the shock absorber is a device used to suppress the reciprocating motion of the spring, which can perform secondary shock absorption.

[0003] In the existing technology, shock absorbers are generally suitable for fixed shafts or connecting rods to play a shock absorbing role, but for partially rotating shafts, there are few devices with shock absorbing effects. In the utility model patent "A shock absorbing shell for a shock absorber connecting rod" with the authorization announcement number CN214092828U, the rotation range of the rotating shaft is limited, but for some rotating shafts with a larger rotation range, the rotation is easy to break the connecting part of the shock absorber. Therefore, a shock absorber that can be used for a rotating shaft is needed to help the rotating shaft to reduce shock. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a shock absorber bracket for a rotating shaft, which can reduce the vibration of the rotating shaft while ensuring the transmission of the rotating shaft, and can reduce the wear of the rotating shaft when vibrations generated by the ground occur.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A shock absorber bracket for a rotating shaft, comprising a shock absorber bracket body, a cavity arranged in the shock absorber bracket body and a rotating shaft body installed in the cavity, a rotating member rotatably connected in the cavity, and a first spring arranged between the rotating member and the rotating shaft body;

[0007] The shock absorber support body is provided with a connecting assembly for connecting the rotating shaft body and the transmission shaft for transmission, and the connecting assembly also includes an auxiliary assembly installed on the shock absorber support body for telescoping.

[0008] Furthermore, the rotating member is rotatably connected to a rotating groove provided on the inner wall of the cavity, the rotating member is fixedly connected to the first spring, the free end of the first spring is fixedly connected to a push plate, and the push plate abuts against one end of the rotating shaft body extending into the cavity.

[0009] Furthermore, the connecting assembly includes a chuck connected to the shock absorber bracket body via a second spring, and the chuck is rotatably connected to the rotating shaft body.

[0010] Furthermore, the auxiliary component includes a first coupling fixedly connected to the rotating shaft body, a plurality of hollow rods are fixedly connected to the first coupling, a telescopic rod is slidably connected inside the hollow rod, and a second coupling for installing the transmission shaft is fixedly connected to the free end of the telescopic rod.

[0011] Furthermore, the hollow rod and the telescopic rod are fixedly connected via a third spring.

[0012] Furthermore, a connecting piece for fixing the shock absorber bracket body is fixedly connected to the shock absorber bracket body.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The present embodiment provides a shock absorber bracket for a rotating shaft, comprising a shock absorber bracket body 2, a cavity 22 arranged in the shock absorber bracket body 2, and a rotating shaft body 1 installed in the cavity 22, wherein a rotating member 23 is rotatably connected in the cavity 22, and a first spring 25 is provided between the rotating member 23 and the rotating shaft body 1.

[0022] The first spring 25 in the cavity 22 can damp the rotating shaft body 1 in the shock absorber bracket body 2. Since the rotating shaft body 1 is in a rotating state, the inner walls of the cavity 22 are all smooth surfaces, and no materials that are prone to wear, such as metal, are used as wall surfaces, thereby reducing friction on the rotating shaft body 1.

[0023] The rotating member 23 is rotatably connected to a rotating groove 24 provided on the inner wall of the cavity 22. The rotating member 23 is fixedly connected to the first spring 25. The free end of the first spring 25 is fixedly connected to a push plate, and the push plate abuts against one end of the rotating shaft body 1 extending into the cavity 22.

[0024] The push plate can abut against the rotating shaft body 1 through the rotating member 23, and can rotate together in the same direction, providing a support point for the rotating shaft body 1 while also providing a shock-absorbing effect on the rotating shaft body 1 through the first spring 25 inside.

[0025] The shock absorber bracket body 2 is provided with a connecting component 3 for connecting the rotating shaft body 1 and the transmission shaft for transmission, and the connecting component 3 includes a chuck 31 connected to the shock absorber bracket body 2 through a second spring 32, and the chuck 31 is rotatably connected to the rotating shaft body 1. The shock absorber bracket body 2 is fixedly connected with a connecting piece 21 for fixing the shock absorber bracket body 2.

[0026] The chuck 31 can be used to limit the position of the rotating shaft body 1 so that the rotating shaft body 1 can rotate only in the cavity 22. After the shock absorber bracket body 2 is fixed in a suitable position through the connecting piece 21, the shafts at both ends are installed.

[0027] The connecting component 3 also includes an auxiliary component 4 installed on the shock absorber bracket body 2 for telescopic operation, and the auxiliary component 4 includes a first coupling 44 fixedly connected to the rotating shaft body 1, and a plurality of hollow rods 42 are fixedly connected to the first coupling 44, and a telescopic rod 41 is slidably connected inside the hollow rod 42. The free end of the telescopic rod 41 is fixedly connected to a second coupling 5 for installing a transmission shaft, and the hollow rod 42 and the telescopic rod 41 are fixedly connected via a third spring 43.

[0028] Through the telescopic rod 41 and the hollow rod 42, the first spring 25 can be extended and retracted at the same time when it is compressed, so as to avoid the shaft connected to the second coupling 5 being squeezed and worn due to the impact force. Through the third spring 43, further shock absorption and lifting can be performed.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
