Roller shutter fatigue test device

Abstract

The invention belongs to the technical field of roller shutter fatigue testing and detecting, and relates to a roller shutter fatigue test device. The top end of a fixed frame is sleeved with a roller shutter to be tested, a telescopic rod of a second air cylinder stretches outwards and then is inserted in a central round hole of an upper connection board of a pull rod of the roller shutter to be tested, the second air cylinder is connected to the top end of a telescopic rod of a first air cylinder, the two ends of the first air cylinder and the two ends of the second air cylinder are in butt joint with air sources connected with an oil-water separator, and a first relay and a second relay which are electrically connected with a controller are connected with the first air cylinder and the second air cylinder respectively; a central rod of the fixed frame is provided with a travel switch which is electrically connected with the controller and a counter respectively, and the counter performs counting to achieve statistics of the pulling frequency of the roller shutter to be tested when the second air cylinder connected with the roller shutter to be tested in an inserted mode descends to touch the travel switch. The roller shutter fatigue test device is reasonable in structure, reliable in principle, easy and convenient to operate, high in automation degree, low in manufacturing cost, simple in test process, good in test effect and environmentally friendly.

Description

Technical field: [0001] The invention belongs to the technical field of roller blind fatigue test and detection, and specifically relates to a roller blind fatigue test device, which is suitable for performing fatigue tests on various forms of roller blinds such as external hanging type and built-in type, so as to test whether the roller blind is used for many times. Whether it can still meet the functional requirements. Background technique: [0002] Roller blinds are a kind of window decoration products. Specifically, the curtain cloth is processed by resin and rolled into a roller shape, and the method of rising and falling with a pull rope or chain has many advantages such as simple and convenient operation, beautiful and simple appearance, firm and durable structure, etc. Advantages: At present, all kinds of roller blinds have been applied to various places such as commercial office buildings, hotels, restaurants, offices, homes, vehicles, etc., especially for sunshade ...

Problems solved by technology

[0002] Roller blinds are a kind of window decoration products. Specifically, the curtain cloth is processed by resin and rolled into a roller shape, and the method of rising and falling with a pull rope or chain has many advantages such as simple and convenient operation, beautiful and simple appearance, firm and durable structure, etc. Advantages: At present, all kinds of roller blinds have been applied to various places such as commercial office buildings, hotels, restaurants, offices, homes, vehicles, etc., especially for sunshade roller blinds on cars and trains. More than ten thousand times, there are a lot of researches on sunshade roller blinds for cars and trains in the prior art. For example, there is a sunshade curtain for the front windshield of a car disclosed in Chinese patent 01257728.6, and a kind of sunshade curtain disclosed in Chinese patent 2005800158724 has been The automotive roller blind system of the sliding part of the brake, a damping roller blind device disclosed in Chinese patent 2010206920090, etc.; but the fatigue test for the roller blind has been blank, and there is no relevant theoretical research specifically for the roller blind fatigue test. and test equipment, so the present invention seeks to design a roller blind fatigue test device to fill the gap in this technical field, realize the fatigue resistance test for various forms of roller blinds, and visually display the number of test pulls, with a higher Practical application value and good economic benefits
