Abstract

The utility model discloses a kind of linkage units for circuit breaker multiple levels operation handle, it includes protective jacket and connecting rod；Protective jacket is bar shaped set, strip groove is equipped in it along its length, the section of strip groove is the U-shaped face for being matched with handle button, several stop bit muscle are equipped in strip groove, stop bit muscle is equipped with the through-hole concentric with circular hole on handle, the outer diameter of connecting rod is matched with the internal diameter of through-hole, and connecting rod is inserted into the through-hole in strip groove on circular hole and stop bit muscle on handle.Protective jacket is placed on outside each operation handle of circuit breaker multiple levels when use, connecting rod is then inserted into the through-hole in strip groove on circular hole on handle and stop bit muscle to guarantee that stable connection is reliable each operation handle and protective jacket；Push on protective jacket any position that can realize the synchronous switching on and off of all operation handles by the restraining force of Anti-slip cover and connecting rod, avoid the occurrence of because breaker synchronisms at different levels it is bad caused by alternate imbalance problem.

Description

Linkage unit for circuit breaker multiple levels operation handle

Technical field

The utility model relates to a kind of circuit breaker multiple levels, more particularly to a kind of connection for circuit breaker multiple levels operation handle Dynamic component.

Background technique

Miniature circuit breaker is also known as air switch (hereinafter referred to as breaker), is suitable for exchange 50/60Hz voltage rating 230/ 400V, the overload and short-circuit protection of rated current to 100A route are used, can also under normal circumstances as route not frequently Numerous operation conversion is used, the generally existing following problem of the operation handle of circuit breaker multiple levels in the market: 1, inconvenient problem, When being embodied in operation handle execution on/off switch operation, operation is uncomfortable, experiences bad.2, (such as 2P when multipole product interlocks Product), multiple handles are only driven by the circular shaft being serially connected between handle, synchronism is bad when closing a floodgate；When multipole product interlocks (such as 4P product), multiple handles are only driven by the circular shaft that is serially connected between handle when closing a floodgate, since size limits, circular shaft it is straight Diameter is mostly small size, is caused when closing a floodgate, if the case where side is excessively concentrated in hand push fixed handle position, causes handle to close a floodgate Complete asynchronous, this is not allowed in breaker, especially the four-pole circuit breaker of three-phase and four-line, be easy to cause the three of moment It is mutually uneven, cause the damage problem of electrical equipment.

Utility model content

The purpose of this utility model is that in view of the deficiencies of the prior art, multipole circuit breaker can be guaranteed by providing one kind Each operation handle synchronous linkage unit when on/off switch.

This linkage unit for circuit breaker multiple levels operation handle provided by the utility model, it includes protective jacket and company Bar；Protective jacket is bar shaped set, is inside equipped with strip groove along its length, and the section of strip groove is be matched with handle button U-shaped Face, strip groove is interior to be equipped with several stop bit muscle, and stop bit muscle is equipped with the through-hole concentric with circular hole on handle, and the outer diameter of connecting rod is matched with The internal diameter of through-hole, connecting rod are inserted into the through-hole in strip groove on circular hole and stop bit muscle on handle.

For ease of operation, the ridge of evagination is equipped with to increase power in the peripheral wall length direction center position of the handle Arm lengths.

In order to further increase operation convenience, stripe shape line is equipped in the outer wall of the ridge.

Preferably, the thickness of the stop bit muscle is made to be less than the gap between adjacent two handle.

Preferably, making the protective jacket insulation sleeve, the connecting rod is metal round rod.

Protective jacket is placed on outside each operation handle of circuit breaker multiple levels by the utility model, and then connecting rod is inserted into strip groove Through-hole on circular hole on handle and stop bit muscle is to guarantee that stable connection is reliable each operation handle and protective jacket；It pushes anti- Any position can be avoided out by Anti-slip cover switching on and off synchronous with the restraining force of connecting rod all operation handles of realization on sheath Now because breaker synchronisms at different levels it is bad caused by alternate imbalance problem.

Specific embodiment

As shown in Figure 1, this linkage unit for circuit breaker multiple levels operation handle provided in this embodiment, including protection Set 1 and connecting rod 2；Circuit breaker multiple levels are the level Four breaker of three-phase and four-line.

As shown in Figure 2 and Figure 3, protective jacket 1 is bar shaped set made of insulating materials, is inside equipped with strip groove along its length 11, the section of strip groove is the U-shaped face for being matched with handle button, is set in strip groove 11 there are two stop bit muscle 12, the thickness of stop bit muscle Degree is less than the spacing between adjacent two operation handle, and stop bit muscle is equipped with the through-hole concentric with circular hole in operation handle 3, through-hole Aperture is equal with circular hole aperture；The outer wall of protective jacket 1 corresponds to ridge 13 of the length direction center position equipped with evagination to increase Torque arm length, the outer surface of ridge 13 are equipped with stripe shape line 14 to operate.

As shown in Fig. 2, connecting rod 2 is round bar made of metal material, outer diameter is matched with the internal diameter of through-hole.It, will when assembly Protective jacket is placed on outside four operation handles 3 of level Four breaker with its strip groove, and stop bit muscle is between progress transverse direction operation handle Then connecting rod is inserted into the through-hole in strip groove on the circular hole and each stop bit muscle in each operation handle to guarantee each behaviour by limit It is reliable to make stable connection between handle and protective jacket；After the assembly is completed after coming into operation, when needing divide-shut brake, need to only it push anti- Ridge can realize all operation handle synchronization actions by the restraining force of Anti-slip cover and connecting rod on sheath, avoid the occurrence of because at different levels Alternate imbalance problem caused by breaker synchronism is bad, ridge is the part of protrusion during being somebody's turn to do, and increases operation Torque arm length can be more laborsaving in manual operation handle, and the stripe shape line of outer surface can increase operational comfort.
