Description

The power failure Automatic disconnector

Technical field

Automatic power-off switch when the utility model relates to a kind of power failure refers to that especially this switch has button and body inside and outside all waterproof and dust reduction capability, and power-on button and cut-off button can not be pressed simultaneously, and have adjustable yoke, and it is reliable to reach switching function, safe in utilization.

Background technology

Power failure Automatic disconnector kind in the market is a lot, and is mostly similar with relay function.But have major defect, the product of for example commonly using is all non-watertight and not dustproof, and there is serious potential safety hazard in this concerning switch, and often security incident promptly takes place thus.Mostly the product of for example commonly using again is that power-on button and cut-off button can press simultaneously, easily cause operate miss, influence the brake hard outage, also has this series products in process of production or in the use, the judder sound of electromagnet is difficult to control with the size of the suction-combining force problem such as need regulate, and these problems all need be taked structural measure when product design.As seen only solve these problems, just operator is closed standard GB 15092.1-2000.

Summary of the invention

According to background technology, the purpose of this utility model is to provide a kind of seal closure that adopts button protection and the inside and outside protection of body, to reach button and body inside and outside integrative chemoprevention water dust reduction capability, the double-colored button that adopts work to be integral, switch is not worked when pressing together, adopts to solve the parts vibration in production and the use and regulate the power failure Automatic disconnector of the scalable yoke of the suction-combining force size.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of power failure Automatic disconnector, mainly by double-colored button (1), seal closure (2) and body (4) are formed, wherein: the double-colored overall structure that double-colored button (1) is made up of power-on button (12) and cut-off button (13), the rotation axis (14) in the middle of its structure connects and composes the seesaw structure with body (4); Seal closure (2) is an overall structure, its top profile is shaped on power-on button seal cover (9) and cut-off button seal cover (10), be shaped on and the corresponding lid wing of power-on button seal cover (9) (11) in the both sides of power-on button seal cover (9), be shaped on outer sealing triangular strip (7) and internal layer sealing triangular strip (8) around in the bottom, the top that seal closure (2) all covers body housing (5) becomes an integral body that seals by collar (6) and the lateral margin clamping on the body housing (5); Body housing (5) inside of body (4) is equiped with electric elements, wherein is provided with the adjustable yoke plate of fixing by adjustable yoke fixed screw (16) (3).

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, seal closure of the present utility model is different from other and commonly uses structure, the sealing cover all covers body circle top, and push down internal layer sealing triangular strip by the plastics collar, realize its inner dustproof and waterproof function, in case seal closure is contained on the body housing on the lateral margin, can utilize the elasticity of outer sealing triangular strip to realize its outer field functions of waterproof and dustproof.Degree of protection reaches IP54, meets national standard.

2, button of the present utility model is a double-colored overall structure, owing to form the seesaw structure with the body housing, can not press simultaneously, has so just avoided unexpected generation, utilizes the lid wing prompting on the seal closure not use energising-button easily simultaneously.

3, the utility model adds an adjustable yoke plate on yoke, and fixes with two screws, can make switch reach optimum Working by the fine adjustment to adjustable yoke.

4, the utility model is simple in structure, and is cheap, and working service is repaired simple and easy.

Among the figure: the double-colored button of 1-, 2-seal closure, 3-adjustable yoke plate, the 4-body, 5-body housing, 6-collar, the outer sealing of 7-triangular strip, 8-internal layer sealing triangular strip, 9-power-on button seal cover, 10-cut-off button seal cover, 11-covers wing, 12-power-on button, 13-cut-off button, the 14-rotation axis, the 16-fixed screw

Embodiment

Illustrate by Figure 1A to Fig. 3 B, a kind of power failure Automatic disconnector, mainly by double-colored button 1, seal closure 2 and body 4 are formed, wherein: the double-colored overall structure that double-colored button 1 is made up of power-on button 12 and cut-off button 13, the rotation axis 14 in the middle of its structure connects and composes the seesaw structure with body 4; Seal closure 2 is an overall structure, its top profile is shaped on power-on button seal cover 9 and cut-off button seal cover 10, be shaped on and power-on button seal cover 9 corresponding lid wings 11 in the both sides of power-on button seal cover 9, be shaped on outer sealing triangular strip 7 and internal layer sealing triangular strip 8 around in the bottom, the top that seal closure 2 all covers body housing 5 becomes an integral body that seals by collar 6 and the lateral margin clamping on the body housing 5; Body housing 5 inside of body 4 are equiped with electric elements, wherein are provided with the adjustable yoke plate of fixing by adjustable yoke fixed screw 16 3.

As seen from the figure, seal closure 2 all covers whole machine body 4 tops, and bilayer (internal layer and skin) protection triangular strip is arranged around it, after body 4 covers are loaded onto seal closure 2, push down internal layer sealing triangular strip 8 with a plastics collar 6, so just realized inner water-proof function.After seal closure 2 was contained on the body 4, outer sealing triangular strip 7 just was pressed on the body housing 5, utilizes the elasticity of triangular strip, has realized waterproof outer dustproof function, and degree of protection reaches IP54, meets the GB15092.1-2000 standard.

Know again,, be easy to generate misoperation, cause unexpected the generation if button is separate.The double-colored button 1 of the utility model is whole, power-on button be green (with The symbol correspondence), cut-off button is red (corresponding with the O symbol), and the two body that unites two into one because body housing 5 is formed the seesaw structure, then can not be pressed simultaneously, and switch is failure to actuate, and has so just avoided unexpected generation, meets safety standard.

When emergency takes place, can press the button red part, reach the effect of brake hard.The green button is not pressed when having a power failure easily, by 11 promptings of lid wing.Double-colored button 1 configuration design unique and beautiful is utilized the colour stability of plastics, has will never fade characteristics.

Know that again the adjustable yoke plate 3 in the electric elements is fixed by two adjustable screws 16, carries out fine adjustment by adjustable screw 16.If electromagnet judder in the production process can be eliminated vibration by the fine adjustment of regulating yoke plate 3, also the suction-combining force of scalable electromagnet makes it reach optimum state.
