Detailed Description

The technical scheme of the present utility model will be clearly and completely described in the following examples.

It will be apparent that the described embodiments are merely some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present utility model and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the utility model herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Example 1

As shown in fig. 1-3, which are preferred embodiments of the present embodiment, a proximity switch with stable installation includes a switch body 1 and two nuts 2, a main thread 11 is disposed on an outer side of the switch body 1, a first fixing thread 21 is disposed on an inner side of the nut 2, the first fixing thread 21 is matched with the main thread 11, and the nuts 2 are screwed on the switch body 1 and can rotate on the switch body 1. A fixing sleeve 3 is arranged on the outer side of each nut 2, and a second fixing thread 31 is arranged in the fixing sleeve 3, wherein the second fixing thread 31 is matched with the main thread 11, but the thread direction of the second fixing thread is opposite to that of the first fixing thread 21.

The proximity switch needs to be matched and installed on other equipment parts provided with installation holes so as to be used normally. During installation, the switch body 1 passes through the mounting hole firstly, then two nuts 2 are screwed inwards from two ends of the switch body 1, after the nuts 2 are attached to equipment parts, the switch body 1 completes preliminary fixed installation, then the fixed sleeve 3 is screwed inwards from two ends of the switch body 1 to the end part to be attached to the nuts 2, and due to the fact that the screw threads between the second fixed screw threads 31 and the first fixed screw threads 21 are opposite in direction, the rotation directions of the fixed sleeve 3 and the nuts 2 are opposite. After the fixing sleeve 3 and the nut 2 are installed in place, the nut 2 can be screwed out only after the fixing sleeve 3 is screwed out, so that the stability of connection between the nut 2 and the switch body 1 is greatly improved.

Be equipped with annular spacing groove 22 on the nut 2, spacing groove 22 opening orientation fixed cover 3, fixed cover 3 lateral part is equipped with and is annular limiting plate 4, fixed cover 3 precess to the in-process that laminates mutually with nut 2, limiting plate 4 cooperation inserts in spacing groove 22 to further reduce the stability degree of being connected between fixed cover 3 and the switch body 1.

Further, a first limiting thread 23 is disposed in the limiting groove 22, the pitch and the rotation direction of the first limiting thread 23 and the main thread 11 are the same, a second limiting thread 41 is disposed on the limiting plate 4, and the pitch and the rotation direction of the second limiting thread 41 and the second fixing thread 31 are the same so as to match with the first limiting thread 23. The limiting plate 4 is screwed into the limiting groove 22 in the same rotation direction as the fixing sleeve 3, so that the fixing sleeve 3 is connected with the nut 2 in a threaded manner, and the nut 2 is further prevented from loosening.

The outer end part of the fixed sleeve 3 is also provided with a hexagonal prism-shaped dismounting plate 5, and the fixed sleeve 3 can be dismounted by using a tool matched with the dismounting plate 5.

Example 2
