Description
Technical Field
[0001] The utility model relates to the technical field of sensing mechanisms, in particular to a simple contact-type sensing mechanism. Background Art
[0002] When installing nuts under high temperature conditions, workers are required to regularly check the installation status of the nuts to prevent the nuts from becoming loose or missing, which could lead to potential safety hazards. Specifically, a sensing mechanism is usually used to detect the installation status of the nuts.
[0003] When using photoelectric sensors and image sensors to detect the size and installation status of nuts, if the nuts are installed in a high-temperature area, there is a problem that the photoelectric sensors and image sensors cannot detect the size of the nuts. Moreover, when the photoelectric sensors and image sensors are installed in a high-temperature area, the high temperature will cause damage to the internal structure of the photoelectric sensors and image sensors, thereby reducing the service life of the photoelectric sensors and image sensors or causing inaccurate detection. It is not convenient to use the sensing mechanism to detect nuts installed in a high-temperature state. For this reason, we propose a simple contact sensing mechanism. Utility Model Content

At the same time, when the detection head contacts the nut, the nut pushes the detection head to move to one side, which has the advantage of improving the detection efficiency of the equipment and solving the problems raised in the above background technology.
[0005] The utility model provides the following technical solution: a simple contact sensing mechanism, comprising a cylinder body, a plug being installed on the internal thread of the rear end of the cylinder body, a guide rod being movably sleeved inside the cylinder body, a gasket being fixedly connected to the middle part of the guide rod, a linear spring being installed on the side of the gasket, a nut being threadedly installed on the front end of the guide rod, a detection pin being fixedly connected to one end of the nut, a hemispherical detection head being fixedly connected to the side of the detection pin, a fixing plate being welded to the outside of the cylinder body, the inner side of the fixing plate being fixedly connected to a limiting slide rail, the inner side of the limiting slide rail being movably sleeved with a mounting plate, and elastic buckles being fixedly connected to both sides of the outside of the mounting plate.

[0010] Preferably, both sides of the mounting plate are clamped inside the limit slide rail, the elastic buckle installed on the side of the mounting plate is arranged outside the fixing plate, and the inner side of the elastic buckle contacts the outside of the fixing plate.
[0011] Preferably, reinforcing plates are fixedly connected to the front and rear ends of the fixing plate, the outer surface of the reinforcing plate is parallel to the outside of the mounting plate, and holes are formed inside the mounting plate.
[0012] Compared with the existing simple contact type induction mechanism, the utility model has the following beneficial effects:
[0013] 1. For the simple contact type induction mechanism, the guide rod is arranged at the front end of the cylinder block. When the detection head contacts the nut to be detected, the nut jacks up the detection head. At the same time, the rear end of the guide rod passes through the inside of the plug, and after the inductor installed inside the plug detects the signal, the position and installation state of the nut can be accurately detected.
[0014] 2. For the simple contact type induction mechanism, a fixing plate is installed outside the cylinder block, and the mounting plate is movably sleeved inside the fixing plate. The position of the mounting plate can be adjusted. By adjusting the position of the mounting plate, the installation position of the device can be regulated to improve the stability and convenience when the installation of the device is limited.
