Description
Technical Field
The utility model belongs to the technical field of screw electrical component technique and specifically relates to a locking device for screw proximity switch quick assembly disassembly.
Background
The proximity switch is a position switch which can be operated without mechanical direct contact with a moving part, and when the sensing surface of the object proximity switch reaches the action distance, the switch can be actuated without mechanical contact and any pressure, so that a direct current electric appliance is driven or a control instruction is provided for a computer PLC device. The proximity switch is a switch type sensor, i.e. a non-contact switch, which has the characteristics of a travel switch and a microswitch, has sensing performance, reliable action, stable performance, fast frequency response, long service life, strong anti-interference capability and the like, and has the characteristics of water resistance, shock resistance, corrosion resistance and the like.
However, for the screw type proximity switch, during installation, auxiliary installation materials such as thread glue are often coated on the contact surface of the screw and the bolt so as to increase the connection strength and ensure the stable installation, but the situation that the disassembly is difficult is also caused; meanwhile, when the device vibrates violently, the bolts on the fixing elements may fall off due to shaking or expansion and contraction, and the components are not fixed firmly.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is exactly in order to solve current screw proximity switch installation intensity low, dismantle inconvenient problem, provides a locking device for screw proximity switch quick assembly disassembly, can guarantee that components and parts connect firmly, prevents that the bolt from reducing maintainer's intensity of labour because of shake or expend with heat and contract with cold not hard up landing.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a locking device for screw proximity switch quick assembly disassembly, includes a fixing base and a fixed element who passes the fixing base, even has a pair of fixing bolt on the fixed element, and fixing bolt is hugging closely the setting of fixing base both sides, still is equipped with a fastening bolt on the fixed element that is located the both sides of fixing base respectively, is equipped with a pressure spring between the fastening bolt of every side and the fixing bolt of corresponding side, and the pressure spring cover is established on the fixed element.
Further, the fastening bolt, the compression spring, the fixing bolt and the fixing element are located on the same axis.
Further, the compression spring is in a compressed state when being installed so as to be used for compressing the connection.
Furthermore, a group of anti-skidding points are arranged on the contact surface of the fixing bolt and the fixing seat, so that the friction coefficient between the fixing bolt and the fixing seat is increased.
Further, the anti-slip points are formed in a zigzag shape.
Furthermore, the roughness of the contact surface of the fixing bolt and the fixing seat is Ra not less than 25.
The technical scheme of the utility model, contact surface area and roughness through increase bolt and fixed position to and add the spring between fixing bolt and fastening bolt, prevented effectively that the unstable condition of components and parts that leads to because of the vibration from taking place, ensured that components and parts can not lead to the bolt pine to take off because of shake or expend with heat and contract with cold, reduced proximity switch's point and examined the number of times, reduced maintainer's maintenance intensity, need not scribble the thread glue on the contact surface of screw rod and bolt simultaneously, made things convenient for holistic dismantlement.
Drawings
Fig. 1 is a structural diagram of the anti-loosening device for the quick assembly and disassembly of the screw type proximity switch of the utility model.
Detailed Description
Example 1
In order to make the present invention more clearly understood, the following description is made with reference to the accompanying drawings, and the embodiments described herein are only used for explaining the anti-loosening device for the screw type proximity switch quick assembly disassembly, and are not used for limiting the present invention.
As shown in fig. 1, a locking device for quick assembly and disassembly of a screw proximity switch comprises a fixed seat 1 and a fixed element 2 penetrating through the fixed seat 1, and is characterized in that:
the fixing element 2 is connected with a pair of fixing bolts 3, the fixing bolts 3 are arranged by clinging to two sides of the fixing seat 1, the fixing elements 2 positioned on two sides of the fixing seat 1 are respectively provided with a fastening bolt 4, a compression spring 5 is arranged between the fastening bolt 4 on each side and the fixing bolt 3 on the corresponding side, and the compression spring 5 is sleeved on the fixing element 2;
the fastening bolt 4, the compression spring 5, the fixing bolt 3 and the fixing element 2 are positioned on the same axis;
a group of sawtooth-shaped anti-slip points 6 are arranged on the contact surface of the fixing bolt 3 and the fixing seat 1, and the roughness Ra of the contact surface of the fixing bolt 3 and the fixing seat 1 is more than or equal to 25.
In the utility model, the compression spring 5 is in a compressed state when being installed so as to compress the connection part; meanwhile, in order to ensure quick assembly and disassembly, auxiliary mounting materials such as thread glue and the like cannot be smeared at the screw and the bolt; in order to prevent the components from being fixed insecurely due to vibration, the contact surface and the contact surface roughness of the bolt and the fixed surface are increased; in addition, for preventing that fixed component is not hard up, increase the spring in fastening bolt and fixing bolt department, guaranteed that fixed component can not loosen because of the bolt that shake or expend with heat and contract with cold lead to and loosen.
After the device of the utility model is used, the failure rate of the equipment is reduced, the benefit is increased, and the time for converting the failure caused by the proximity switch into the halt time is 58 minutes in the whole year of the electrical equipment failure in the medium plate factory of Nanjing Steel works Limited company; according to the hourly output of 245 tons/hour and the profit of 300 yuan of ton steel, 0.16 ten thousand yuan is required to be invested for the total reconstruction of the whole-line proximity switch. Thus, the specific benefits are as follows:
the benefit is 300 × 245 =7.1 ten thousand;
newly-increased operation cost in year: the cost in the first 5 years is 0;
the new year is old: 0.16 × 0.95/15=0.01 ten thousand yuan;
annual interest: 0.16 × 0.055=0.01 ten thousand yuan;
the total benefit is as follows: 7.1-0.01-0.01=7.08 ten thousand yuan.
In addition, use the utility model discloses a behind the device, reduced maintainer's intensity of labour, proximity switch is examined by 3 points on a shift, descends to 1 point and examines.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
