Abstract
The utility model relates to a theft-proof device for a switch of a switching box door, which is composed of a crank slide bar mechanism, a locking mechanism and an opening mechanism. The crank slide bar mechanism is positioned at the middle position of a door side edge, the locking mechanism is positioned at the inner end part of the crank slide bar mechanism, and a slide bar is connected respectively with the upper and the lower ends of the middle part of a main plate for the crank slide bar mechanism and passes through a support frame. The theft-proof purpose is achieved by that the locking mechanism is opened by the special opening mechanism, and the utility model has the advantages of good theft-proof and pry-proof performance, high safety, simple structure and safe and convenient operation. A special opening tool has unusual design and has difficult imitation, and the problems that components at the inner part of a wild switching box of an oil field are stolen and the electricity is stolen are solved fundamentally.
Description
The utility model relates to the body structure gate and locks antitheft sled technology, particularly is a kind of distribution box door switch anti-theft device.
In the scene of production operation in the open air, various power distribution cabinets, distribution box etc., the door theftproof performance is poor, and what have uses simple and easy lock, easy-to-rust; What have uses simple Tiebar structure, and specific purpose tool designing technique poor performance just can be opened with general tool, often causes the box house components and parts to lose, and influence is produced.By retrieval, a kind of " the antitheft control cubicle of motor of oil extractor " patent No. 94216577.2 is arranged, control gate uses anti-theft lock and anti-theft bolt to fix, though theftproof performance is arranged, the cost height from locking itself, does not have innovation.
In view of the above-mentioned shortcoming and defect of prior art, the purpose of this utility model just is to provide that a kind of to have a theftproof performance good, simple in structure, and specific purpose tool is opened, and is cheap, the distribution box door switch anti-theft device that is easy to make.
Specific embodiments of the present utility model is:
This distribution box door switch anti-theft device is made up of slide crank linkage, retaining mechanism and opener three parts.The slide crank linkage is positioned at door centre position, 1 limit, and retaining mechanism is positioned at slide crank linkage inner end portion.It is characterized in that: the slide crank linkage is by collar bush 11, pad 12, nut 13, main shaft 7, and mainboard 5, locking nut 6, attachment pegs 4, locking bar 3, support 2 is formed.Collar bush 11 passes door 1 and is fixed on the door 1 by pad 12, nut 13, main shaft 7 passes from collar bush 11 endoporus A, mainboard 5 is contained on the main shaft 7 by hole C, fixing by locking nut 6, attachment pegs 4 is passed mainboard 5 upper and lower hole D and locking bar 3 links, and must pass from support 2 through holes earlier before locking bar 3 connects.Retaining mechanism is by lock tube 10, pad 12, nut 13, and lock shaft 8 is formed.Lock tube 10 passes door 1 by pad 12, and nut 13 is fixed on the door 1, and the internal thread of the external screw thread of lock shaft 8 and lock tube 10 centre bore G links, and the termination of lock shaft 8 just in time leads to the lockhole B of mainboard 5, and this moment, this device then was in locking state.Opener is made up of opener 14 and auxiliary opener 15.
Uniform three through hole F around main shaft 7 and the lock shaft 8 end E orifice ring walls in slide crank linkage and the retaining mechanism in the above-mentioned distribution box door switch anti-theft device, and not at grade.
Opener 14 tops are spherical structure in the opener of above-mentioned distribution box door switch anti-theft device, and there is a through hole H at the center, and the bottom is three not isometric arcuate claws structures, and there is claw hook the lower end of pawl, and pawl outwards colludes, and three claw hooks are not on same plane.
The utility model and prior art contrast, have the following advantages: the gate retaining mechanism is safe and reliable, and antitheft sled performance is good, the design of special opening instrument is unique, be difficult for copying, simple in structure, easy for installation, with low cost, be convenient to make, can prevent effectively that parts are lost in the casing, reduce the loss, this is for guaranteeing field work and safeguard ordinary production to have great social significance.
