Description

Technical Field

[0001] The utility model relates to a catheter transmission device. Background Art

[0002] Traditional catheter transmission line equipment mostly uses chains or belts for transmission. The chain structure needs to be lubricated frequently, which is easy to pollute the environment and produce a lot of noise. In addition, the medical automation production field usually has high environmental requirements, so the chain structure is difficult to meet production needs; the belt structure is not only noisy, but also because the belt is soft, it usually requires additional support structures, which leads to a large space occupation. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a catheter transmission device which occupies a small space, is clean and hygienic, and has low noise.

[0004] The utility model adopts the following technical solution: a catheter transmission device, comprising lifting parts that are identical and symmetrically arranged on both sides, and a transmission part located between the lifting parts on both sides, wherein:

[0005] The transmission part includes two layers of transmission lines, the upper and lower layers of transmission lines, which are connected to the lifting parts on both sides; on each layer of transmission line, a number of sliders are installed at equal distances on the horizontally arranged double-axis guide rails, and a main line tray for holding the catheter is installed above each slider;

[0006] In the lifting part on each side, the vertically arranged cylinder is connected to the screw assembly above the fixed plate through a floating joint. The screw in the screw assembly is docked with the double-axis guide rails in the two-layer transmission line before and after lifting. The screw is located between the double-row linear guide rails and is parallel to the double-row linear guide rails. The screw is fixed to the fixed plate through a screw guide rail fixing seat. The screw is connected to the servo motor drive; a pushing fixture is bridged on the screw and the double-row linear guide rails, and the pushing fixture pushes the main line tray entering the lifting part to the transmission part;

[0007] The lifting parts on both sides repeat the above actions to make the main line tray circulate around a transmission direction.

[0008] Preferably, the dual-axis guide rail is fixedly mounted on a strip profile, and the profile is supported by main line supports distributed at equal distances, which plays a role in stabilizing the transmission part.

[0009] Preferably, a limit cylinder is provided on the profile, which is used to clamp the main line tray on the main line of the transmission part to prevent the main line tray on the screw rod assembly from interfering with the main line tray on the main line of the transmission part when the lifting parts on both sides are lifted.

[0010] Preferably, a positioning cylinder is provided on the fixed plate, and the positioning cylinder is used to tighten the main line tray on the screw rod assembly to prevent the main line tray on the screw rod assembly from interfering with the main line tray on the main line of the transmission part when the lifting parts on both sides are lifted.

[0011] Preferably, the pushing jig includes a base and a protrusion located on the top of the base, the base is connected to the screw rod and the double-row linear guide rails, and the protrusion abuts against the main line tray when moving out along the screw rod, so as to quickly push the main line tray on the screw rod assembly onto the main line of the transmission part.

[0012] The beneficial effects of the utility model are as follows: the utility model can perfectly replace the traditional belt transmission or chain transmission; as a new transmission mode, the utility model can better meet the needs of production. BRIEF DESCRIPTION OF THE DRAWINGS
