Description

High-precision plum blossom spline crank

Technical Field

The utility model relates to an spinning technical field especially relates to high-accuracy plum blossom spline crank.

Background

Spinning originated in the United states is contaminated with the intense United states taste, and the activity is four-shot, and the enthusiasm is fast, but the sports can be executed abroad without age limitation because the scientificity in design ensures the safety of participants, and the intensity of the sports is completely controllable and is suitable for all people with sports ability.

The spinning is equipped with the plum blossom crank on, and the plum blossom crank mainly used is connected with the disc on the bicycle, drives the crank through the running-board and drives the disc. The plum blossom crank is a high-precision part and is installed on the spinning to ensure stable installation. In the prior art, the high-precision plum blossom spline crank disc is inconvenient to fix.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the fixed comparatively inconvenient shortcoming of high-accuracy plum blossom spline crank disc, and the high-accuracy plum blossom spline crank that proposes.

In order to realize the purpose, the utility model adopts the following technical scheme:

high-accuracy plum blossom spline crank, including disc, connector, crank mechanism, the storage tank has been seted up on the disc, the through-hole has been seted up in the disc, the contact has the connector on the disc, be provided with crank mechanism on the connector.

Preferably, the number of the through holes is five, and the five through holes are uniformly distributed on the disc. Through setting up the through-hole for it is not hard up to be convenient for prevent through-hole and screw cooperation after the disc is fixed.

Preferably, the disc is provided with a connecting key, and the connecting key is connected with the connector in a sliding manner. Through setting up the connecting key for the connector is convenient for rotate the disc.

Preferably, the crank mechanism comprises a crank, a handle and a square hole, the crank and the connector are installed, the crank is contacted with the handle, and the crank is provided with the square hole. Through setting up above mechanism for but crank mechanism adjusting length, and then make moment change, it is more laborsaving.

Preferably, a square rod is installed on the handle, and the square rod is connected with the square hole in a sliding mode. The handle and the crank are connected by arranging the square rod.

Preferably, the crank and the handle are made of the same material, and the end faces of the crank and the handle are the same in size. The handle and the end face of the crank are arranged to be same in size, so that the handle and the end face of the crank are tightly attached.

The working principle is as follows: during the use, cup joint the connector on the connecting key, then rotate the connector through crank mechanism, in this process, can take out the part through the handle with the square bar from the square hole, and then make moment elongated, make during the use, it is more laborsaving, use the completion back, loosen the handle, make handle and crank contact, through setting up the disc, the connector, the connecting key, crank mechanism isotructure, act on the connector through crank mechanism, make connector and connecting key cooperation, rotate the connecting key, and then make the connecting key rotate the disc, and then make the device convenient to use.

The utility model has the advantages that: this high-accuracy plum blossom spline crank is through setting up disc, connector, connection key, crank mechanism isotructure, through crank mechanism effect on the connector for connector and connection key cooperation rotate the connection key, and then make the connection key rotate the disc, and then make plum blossom spline crank convenient to use.

Drawings

Fig. 1 is a schematic view of the overall structure of the high-precision plum blossom spline crank provided by the present invention;

fig. 2 is the left side view of fig. 1 of the high-precision plum blossom spline crank provided by the utility model.

In the figure: 1. a disc; 2. a through hole; 3. a connector; 4. a connecting key; 5. a crank mechanism; 51. a crank; 52. a handle; 53. a square hole; 54. a square bar.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a high-precision plum blossom spline crank comprises a disc 1, a connector 3 and a crank mechanism 5, wherein an accommodating groove is formed in the disc 1, a through hole 2 is formed in the disc 1, the connector 3 is in contact with the disc 1, and the crank mechanism 5 is arranged on the connector 3.

In this embodiment, there are five through holes 2, and the five through holes 2 are uniformly distributed on the disc 1. Through setting up through-hole 2 for be convenient for prevent that disc 1 is not hard up through-hole 2 and screw cooperation after disc 1 is fixed.

In this embodiment, the disc 1 is provided with a connecting key 4, and the connecting key 4 is slidably connected with the connector 3. Through setting up the connector 4 for connector 3 is convenient for rotate disc 1.

In this embodiment, the crank mechanism 5 includes a crank 51, a handle 52 and a square hole 53, the crank 51 is mounted on the connector 3, the handle 52 contacts the crank 51, and the square hole 53 is opened on the crank 51. Through setting up above mechanism for crank mechanism 5 adjustable length, and then make moment change, it is more laborsaving.

In this embodiment, a square bar 54 is mounted on the handle 52, and the square bar 54 is slidably connected with the square hole 53. The handle 52 and the crank 51 are connected by providing a square bar 54.

In this embodiment, the crank 51 and the handle 52 are made of the same material, and the end faces of the crank 51 and the handle 52 are the same size. The handle 52 and the crank 51 are arranged to have the same size, so that the two are tightly attached.

The specific implementation process is as follows: when the plum blossom spline crank of the spinning is assembled, the connector 3 is sleeved on the connecting key 4, then the connector 3 is rotated through the crank mechanism 5, in the process, the square rod 54 can be partially drawn out from the square hole 53 through the handle 52, so that the torque is lengthened, the labor is saved during use, after the use is finished, the connecting key 4 is rotated by the connecting key 4 through the arrangement of the structures of the disc 1, the connector 3, the connecting key 4, the crank mechanism 5 and the like, the crank mechanism 5 acts on the connector 3, so that the connector 3 is matched with the connecting key 4, and the disc 1 is rotated by the connecting key 4, so that the device is convenient to use;
