Electric push rod

Abstract

The invention discloses an electric push rod. An outer pipe, sleeves arranged in the outer pipe and components arranged in the sleeves are included. The outer pipe is in a long round pipe shape. A step inner diameter is set in the outer pipe. The multiple sleeves are arranged. Electric push rod components are fixedly arranged on the inner walls of the sleeves, and the multiple sleeves are sequentially clamped in the outer pipe in a sliding manner. A deep hole machining method is adopted in the electric push rod, the round pipe inner diameter is machined into a step shape, the space differenceis formed between the two ends of the round pipe and a component needing to be installed, meanwhile, the sleeves are provided with the components in a modular manner so that the components can be better installed in the middle of the round pipe, so that the product is more convenient to install and maintain, and the product is firmer and more durable. Various problems that due to an original pushrod round pipe inner diameter clamp ring groove structure, the installing efficiency is low, maintaining is extremely not convenient, and the product is not firm or durable enough are solved.

Description

technical field [0001] The invention relates to the technical field of electric push rods, in particular to an electric push rod. Background technique [0002] Electric push rods can be used in various fields such as medical treatment, equipment, doors and windows, furniture, kitchen utensils, etc., and are driven by motors to play the role of power drive; inside the outer tube of electric push rods, many parts need to be installed, such as motors and motor fixing seats, Gearboxes, flanges and flange holders, bearings and bearing sleeves, switches and switch wires, switch positioning sleeves, T-screws, transmission parts, etc. [0003] In the existing electric push rod, multiple snap ring grooves are dug in the inner diameter of the outer tube, which are used for the installation and positioning of related parts. inside the pipe, and then positioned through the snap ring groove, because there are many parts that need to be installed in the outer pipe, which has the followin...

AI Technical Summary

Problems solved by technology

[0003] In the existing electric push rod, multiple snap ring grooves are dug in the inner diameter of the outer tube, which are used for the installation and positioning of related parts. inside the pipe, and then positioned through the snap ring groove, because there are many parts that need to be installed in the outer pipe, which has the following defects: (1) When the parts are installed through the snap ring groove, the parts need to be installed one by one in order Slowly install them into the outer tube one by one. Since the inner diameter of the outer tube is relatively small, the installation of parts one by one is very time-consuming and laborious, and the efficiency is very low; (2) also because of the form of the snap ring groove, as long as a certain part in the outer tube is broken , it is necessary to manually take out the parts one by one in such a small inner diameter, replace the broken parts and put them in one by one, which makes the maintenance of the electric push rod very difficult and time-consuming. Non-skilled workers, it is difficult to repair and replace parts; (3) Due to the form of the snap ring groove, the upper and lower inner diameters of the outer tube are consistent, because the sizes of the parts are different, after installation, the inside of the outer tube is not occupied by parts The part is hollow, and if there is extra space inside, it is easy to cause deviations in the position of parts inside the outer tube due to external power when the electric push rod is working, which will affect the function or make the parts more accurate. It is easy to be damaged; (4) Because the inside of the outer tube is hollow, the entire electric push rod is not strong enough, not durable enough, and even the bad situation that the electric push rod breaks the outer tube due to the working power may occur
