Description

Technical Field

[0001] This utility model relates to the field of fastening tool technology, and in particular to an M30 proximity switch fastening tool. Background Technology

[0002] A proximity switch is a position switch that operates without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, the switch actuates without mechanical contact or pressure, thereby driving DC electrical appliances or providing control commands to computer devices. In automatic control systems, it can be used for limit switches, counting, and positioning control. A proximity switch is a type of switch sensor (contactless switch) that combines the characteristics of limit switches and microswitches with sensing capabilities. It is reliable, stable, has a fast frequency response, long service life, and strong anti-interference ability. It is also waterproof, shockproof, and corrosion-resistant. With its characteristics, proximity switches are widely used in industries such as metallurgy and are an indispensable part of the metallurgical industry. Proximity switches come in different diameters, with the 30mm diameter M30 proximity switch being the most common and frequently used specification in the field. How to tighten, adjust, and replace proximity switches that are used in large quantities in the field is a very important technology. Due to the installation location of proximity switches in the field, ordinary tightening wrenches cannot meet the needs of the field, and special tools are required. Therefore, this application proposes an M30 proximity switch tightening tool to solve the problem of not being able to meet the field requirements mentioned above. Utility Model Content

[0003] The main purpose of this utility model is to provide an M30 proximity switch fastening tool, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An M30 proximity switch fastening tool includes a fixed base, a proximity switch, a retaining ring, and a fastening tool. The fixed base is made of stainless steel and has a 30mm diameter elongated hole. The outer wall of the proximity switch has external threads, and the inner wall of the retaining ring has internal threads. The fastening tool includes an operating handle, one end of which has a fastening plate, and the end of the fastening plate away from the operating handle has a clamping groove.

[0006] Preferably, the proximity switch is in communication with the elongated hole in the base.

[0007] Preferably, there are two proximity switches, and each proximity switch has two retaining rings fitted on its outer wall. The proximity switches are respectively threaded to the internal threads of the retaining rings via external threads.

[0008] Preferably, the two retaining rings on the proximity switch are located on the front and rear sides of the fixed base, respectively, and the sides of the two retaining rings on the proximity switch that are close to each other are in contact with the outer walls of the two sides of the fixed base.

[0009] Preferably, the outer dimensions of the fixing ring match the inner dimensions of the clamping groove.

[0010] Preferably, the end of the operating handle away from the fastening plate has a hanging hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By adding this proximity switch fastening tool, the proximity switch can be securely fixed to the original base, preventing loosening due to poor fastening and subsequent mechanical position detection errors. This can ultimately lead to the malfunction of automatic or semi-automatic control systems. In the steel rolling industry, inaccurate proximity switch detection can easily cause steel piling. This tool also avoids situations where the proximity switch cannot be adjusted or fastened due to the actual installation location on site. After being applied to the field, this tool has prevented many steel piling accidents, greatly improved work efficiency, and enhanced the quality of steel products. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-3As shown, an M30 proximity switch fastening tool includes a fixed base 1, a proximity switch 2, a retaining ring 3, and a fastening tool 4. The fixed base 1 is made of stainless steel and has a base elongated hole 11 with a diameter of 30mm. The outer wall of the proximity switch 2 is provided with an external thread 21, and the inner wall of the retaining ring 3 is provided with an internal thread 31. The fastening tool 4 includes an operating handle 43, one end of which is provided with a fastening plate 41, and the end of the fastening plate 41 away from the operating handle 43 is provided with a clamping groove 42.

[0019] Specifically, the proximity switch 2 is connected to the elongated hole 11 in the base.

[0020] Specifically, there are two proximity switches 2. Each proximity switch 2 has two retaining rings 3 fitted on its outer wall. The proximity switches 2 are threadedly connected to the retaining rings 3 through external threads 21 and internal threads 31.

[0021] Specifically, the two retaining rings 3 on the proximity switch 2 are located on the front and rear sides of the fixed base 1, respectively, and the sides of the two retaining rings 3 on the proximity switch 2 that are close to each other are in contact with the outer walls of the two sides of the fixed base 1.

[0022] Specifically, the outer dimensions of the retaining ring 3 match the inner dimensions of the clamping groove 42.

[0023] Specifically, the end of the operating handle 43 away from the fastening plate 41 has a hanging hole 44. When not in use, the hanging hole 44 can be used with a hook for hanging so as to store it and avoid loss.

[0024] Working principle:

[0025] The commonly used fixed base 1 in the on-site design is made of stainless steel to prevent water vapor corrosion. The long hole 11 of the base has a diameter of 30mm and is used to fix the universal M30 model limit. The limit can be adjusted left and right and forward and backward, which can avoid the detection error caused by the back and forth swing of the push roller on site. Taking the on-site moving roller detection as an example, after the proximity switch 2 passes through the long hole 11 of the base, its two external fixing rings 3 can be clamped on both sides of the fixed base 1 to fix and limit the proximity switch 2 on the fixed base 1. When it is necessary to tighten or adjust after rotation, a fastening tool 4 is required. Compared with the traditional wrench, the fastening tool 4 can make rotation adjustment more simple and convenient. Insert the clamping groove 42 of the fastening plate 41 into the outside of the fixing ring 3, and the operating handle 43 can be rotated to drive the fixing ring 3 to rotate, thereby completing the rotation adjustment of the fixing ring 3 and achieving the tightening effect.
