Abstract
The utility model discloses a vacuum circuit breaker separating brake oil bumper, including the piston of cylinder and activity about the cylinder inner chamber is done, the piston bottom is equipped with reset spring, and the top land is connected with the piston rod, the under shed and the base fixed connection of cylinder, and the upper shed screw of cylinder body connects and the fixed hydro -cylinder lid that is equipped with soon, and the hydro -cylinder lid is equipped with the centre bore and passes by the piston rod activity, sealing washer about being equipped with between hydro -cylinder lid centre bore and the piston rod excircle, its characterized in that: the lower terminal surface of piston sets up the ladder counter bore, and oil buffering hole has all been offered to the pore wall of every section ladder counter bore. The utility model discloses compare that the prior art structure is simpler, the action is more reliable, cushioning effect in the time of can high -quality completion vacuum circuit breaker separating brake improves vacuum circuit breaker operating mass with rated load.
Description
[technical field]
The utility model relates to a kind of vacuum circuit-breaker, is specifically related to a kind of separating brake oil bumper of vacuum circuit-breaker.
[background technology]
Vacuum circuit-breaker have volume little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, apply comparatively universal in power distribution network.For reducing the impact that the action of vacuum circuit-breaker separating brake brings, the separating brake action component of vacuum circuit-breaker often will rely on buffer to cushion, for this reason, applicant is had to apply for the patent No. 201420347536.6 on June 26th, 2014 specially, the patent of title " a kind of oil bumper ", the oil bumper product that this patent provides better achieves the buffering of separating brake action, but in actual application, have the following disadvantages: structure relative complex, there is hysteresis quality in the action of steel ball, can not the reliability of better safety action, can not the cushioning effect of high-quality when completing vacuum circuit-breaker separating brake, the direct work quality affecting vacuum circuit-breaker.
[summary of the invention]
For background technology Problems existing, the purpose of this utility model aims to provide that a kind of structure is simpler, action is more reliable, can the cushioning effect of high-quality when completing vacuum circuit-breaker separating brake, improves the vacuum circuit-breaker separating brake oil bumper of vacuum circuit breaker operation quality.
The utility model is implemented by the following technical programs:
Vacuum circuit-breaker separating brake oil bumper, comprise cylinder barrel and make up and down piston at inner cavity of cylinder, piston base is provided with back-moving spring, top land is connected with piston rod, the under shed of cylinder barrel is fixedly connected with base, the upper shed screw thread of cylinder body spins and is fixed with oil cylinder cover, oil cylinder cover is provided with centre bore and passes by piston rod activity, upper-lower seal circle is provided with between oil cylinder cover centre bore and piston rod cylindrical, it is characterized in that: the lower surface of described piston arranges ladder counterbore, the hole wall of every section of ladder counterbore all offers oily cushion hole.
Described ladder counterbore is divided into upper, middle and lower three sections, and the aperture of hypomere ladder counterbore is greater than the external diameter of described back-moving spring.
Described piston and piston rod are structure as a whole.
Have employed the oil bumper of technique scheme, ladder counterbore is set in piston base by direct and on the hole wall of ladder counterbore, offer cushioning effect when oily cushion hole realizes vacuum circuit-breaker separating brake, compare the steel ball of background patents technology and sub-oil channel structure, structure is more simple, action is also more reliable, can the cushioning effect of high-quality when completing vacuum circuit-breaker separating brake, and then improve the work quality of vacuum circuit-breaker.
[accompanying drawing explanation]
The utility model has the following drawings:
Fig. 1 is structure chart of the present utility model.
[embodiment]
By specific embodiment the utility model to be described in detail below in conjunction with accompanying drawing and to illustrate:
As shown in the figure, vacuum circuit-breaker separating brake oil bumper of the present utility model, comprise cylinder barrel 3 and make up and down piston 4 at cylinder barrel 3 inner chamber, back-moving spring 5 is provided with bottom piston 4, piston 4 top is connected with piston rod 1, piston 4 and piston rod 1 are structure as a whole, the under shed of cylinder barrel 3 is fixedly connected with base 6, the upper shed screw thread of cylinder barrel 3 spins and is fixed with oil cylinder cover 2, oil cylinder cover 2 is provided with centre bore and passes by piston rod 1 activity, upper-lower seal circle is provided with between oil cylinder cover 2 centre bore and piston rod 1 cylindrical, the lower surface of described piston 4 arranges ladder counterbore, described ladder counterbore is divided into upper, middle and lower three sections, the hole wall of epimere ladder counterbore 7 offers an oily cushion hole 10, the hole wall of stage casing ladder counterbore 8 offers an oily cushion hole 11, the hole wall of hypomere ladder counterbore 9 offers two oily cushion holes 12, the aperture of hypomere ladder counterbore 9 is greater than the external diameter of described back-moving spring 5.
