Problems solved by technology
[0004] The purpose of the present invention is to provide an elastic structure that can reduce friction for a proximity switch installation structure, to solve the disadvantages of the traditional proximity switch installation form, resulting in the inability of the traditional proximity switch to accurately detect signals, especially in places with high dust concentrations. In the environment, after a period of use, the surface is covered with dust, which seriously affects the accuracy of detection; the traditional proximity switch installation structure cannot move the distance between the trolley and the fixed track, and there is a phenomenon of signal interruption; in addition, the traditional proximity switch mobile detection device and the fixed track Hard direct contact, high friction, short service life, frequent replacement of spare parts

Embodiment Construction
[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] Such as Figure 1-5 As shown, an elastic structure that can reduce friction for a proximity switch installation structure includes a fixed track 1 and a supporting steel column 4, and the two ends of the side wall on one side of the fixed track 1 are respectively fixedly provided with supporting steel columns 4, The two supporting steel columns 4 are perpendicular to the fixed track 1, and one end of each supporting steel column 4 is provided with a square plate 5, and the side wall on the other side of the fixed tra...

The invention discloses an elastic structure capable of reducing friction force for a proximity switch mounting structure, and the structure comprises a fixed rail and supporting steel columns; the two ends of the side wall of one side of the fixed rail are respectively and fixedly provided with the supporting steel columns; a first nut is enabled to rotate, so due to the threaded connection between the first nut and a connecting rod, the first nut is enabled to push a stopping disc to move downwards; a top plate is fixed between the first nut and a second nut through the second nut, so the connecting rod extends outside an inner plate; when the distance between the movable trolley and the fixed rail is small, the first nut is rotated to move upwards, then the second nut is rotated upwards, and the connecting rod stretches into the inner side of the inner plate, so when the moving trolley moves and deviates, under the action of the elastic force of the spring, the two stand columns apply the elastic force to the angle steel in the moving detection device, the moving detection device is in elastic contact with the fixed rail all the time, signal detection is ensured, and the problemthat a traditional proximity switch cannot accurately detect signals is solved.
Description
technical field [0001] The invention relates to the field of proximity switch installation equipment, in particular to an elastic structure capable of reducing friction for a proximity switch installation structure. Background technique [0002] Proximity switch, also known as contactless proximity switch, is an ideal electronic switch sensor. When the metal detection body is close to the sensing area of the switch, the switch can send out electrical instructions without contact, without pressure, without sparks, and accurately reflect the position and stroke of the motion mechanism. Even if it is used for general stroke control, its positioning accuracy and operating frequency , service life, convenience of installation and adjustment, and adaptability to harsh environments are unmatched by general mechanical limit switches. Widely used in machine tools, metallurgy, chemical industry, textile and printing industries. In the automatic control system, it can be used as th...
