Abstract
The utility model relates to a replacement auxiliary tool of a vacuum bulb, which is characterized in that: the replacement auxiliary tool comprises a screw (1), a hook seat (2) fixed on the top of the screw (1), a support block (4) sleeved with the middle part of the screw and capable of vertically moving, a hook (3) fixed on the hook seat (2) and an adjustment nut (5) arranged below the bottom of the support block (4) and sleeved with the screw (1). While in use, a movable contact of the vacuum bulb is hooked by the hook, the installation distance is adjusted by the adjustment nut and then the support block is fixed, thus the direct disassembly process of the vacuum bulb is free from the conquer force of a vacuum switch self energy-storage mechanism, the installation distance and the prior consistence are ensured, the time and labor are saved, the replacement speed is relatively quick and the installation precision is relatively high.
Description
Technical field
The utility model relates to a kind of replacing aid of vacuum bubbles.
Background technology
Vacuum switch is indispensable part in high-tension switch cabinet, and SIEMENS vacuum switch 3AH4 series is because of reliable stable, and is easy for installation quite extensive in industrial and mining enterprises' application.Yet the core component using this series switch is a vacuum bubbles, and the quality of vacuum bubbles directly has influence on the useful life of switch.Yet itself has useful life vacuum bubbles, need periodic replacement, but vacuum switch is installed in generally in the cabinet; The space is narrow and small, the stored energy mechanism of vacuum switch own to overcome force rate bigger, and three vacuum bubbles of vacuum switch are to move simultaneously; This just need guarantee to change the time interval strict conformance, so it is very high to change requirement, does not have aid during workman's manual operations in the past; Replacing speed is slower, and installation accuracy is lower.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of power that overcomes that can avoid the stored energy mechanism of vacuum switch own is provided, and changes rapid speed, the replacing aid of the vacuum bubbles that installation accuracy is higher.
The purpose of the utility model is achieved in that
The replacing aid of the utility model vacuum bubbles; Comprise screw rod, the top of said screw rod is fixed with the hook seat, and the middle part is with back-up block; Said back-up block can move up and down; Be fixed with hook on the said hook seat, the below, bottom of said back-up block is provided with the adjustment nut, and said adjustment nut sleeve is on screw rod.
Compared with prior art, the beneficial effect of the utility model is:
When the replacing aid of this vacuum bubbles uses hook caught on the moving contact of vacuum bubbles; Use the adjustment nut to adjust the spacing of installation and will fix back-up block subsequently; Can not receive the power that overcomes of the stored energy mechanism of vacuum switch own during so direct dismounting vacuum bubbles, guarantee that installing space is with original consistent, time saving and energy saving; And the replacing rapid speed, installation accuracy is higher.
Description of drawings
Fig. 1 is the structural representation of the replacing aid of the utility model vacuum bubbles.
Wherein: screw rod 1, hook seat 2, hook 3, back-up block 4, adjustment nut 5.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of replacing aid of vacuum bubbles, comprises screw rod 1; The top of said screw rod 1 is fixed with hook seat 2; The middle part is with back-up block 4, and said back-up block 4 can move up and down, and is fixed with hook 3 on the said hook seat 2; The below, bottom of said back-up block 4 is provided with adjustment nut 5, and said adjustment nut 5 is enclosed within on the screw rod 1.
When the replacing aid of this vacuum bubbles uses hook caught on the moving contact of vacuum bubbles; Use the adjustment nut to adjust the spacing of installation and will fix back-up block subsequently; Can not receive the power that overcomes of the stored energy mechanism of vacuum switch own during so direct dismounting vacuum bubbles, can easy removal.When new vacuum bubbles is installed; As long as new vacuum bubbles is fixed with back-up block according to original position, unclamp the replacing that aid is just accomplished a vacuum bubbles, other two operations too; Just can guarantee that installing space is all consistent with originally; Time saving and energy saving, and change rapid speed, installation accuracy is higher.
Claims (1)
1. the replacing aid of a vacuum bubbles; It is characterized in that: it comprises screw rod (1), and the top of said screw rod (1) is fixed with hook seat (2), and the middle part is with back-up block (4); Said back-up block (4) can move up and down; Be fixed with hook (3) on the said hook seat (2), the below, bottom of said back-up block (4) is provided with adjustment nut (5), and said adjustment nut (5) is enclosed within on the screw rod (1).
