Abstract
The utility model relates to a push connecting rod used for a direct operated magnetic latching relay, and the push connecting rod belongs to one part of a magnetic latching relay. The push connecting rod comprises a push connecting rod body which is provided with a rotating shaft hole. Two ends of the push connecting rod body are equipped with a first arm and a second arm respectively. A connecting hole, a long round hole, is disposed in the first arm. A connecting portion is disposed on the second arm. Compared with the prior art, the push connecting rod has the following advantages and beneficial effects: the push connecting rod is simple in structure and reasonable in design; the push connecting rod body is hinged to both a push rod and a push sheet, so that the push connecting rod runs smoothly, exhibits less impact force and is more reliable to use; and the connecting hole is a long round hole so as to allow a certain reservation space when cooperating with the push rod, such that the push connecting rod body exhibits higher resistance to impact.
Description
Technical field
The utility model relates to a kind of connecting rod of the promotion for the direct-acting magnet latching relay, belongs to parts of magnetic latching relay.
Background technology
A kind of electronic control device of magnetic latching relay plays the effects such as automatic adjusting, safeguard protection, change-over circuit in circuit, be widely used in electric power protection, automation, motion, remote control, measurement and the device such as communicate by letter in.Straight pull magnetic latching relay of the prior art, that motion by controlling catch bar drives the first pushing piece motion, thereby the motion of second pushing piece of control connection on the first pushing piece, and the second pushing piece is connected and controls the motion of movable contact spring with movable contact spring, carry out the state of control relay with this, because the structural design of the first pushing piece of the prior art is unreasonable, while causing the first pushing piece motion, the first pushing piece and the second pushing piece impact larger, easily cause wearing and tearing, and easily break away from and lost efficacy.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and cost is low, and service-strong is for the promotion connecting rod of direct-acting magnet latching relay.
The technical scheme in the invention for solving the above technical problem is: should be for the promotion connecting rod of direct-acting magnet latching relay, comprise the promotion con-rod only, it is characterized in that: described promotion con-rod only is provided with shaft hole, the two ends of described promotion con-rod only are provided with the first arm and the second arm, described the first arm is provided with connecting hole, this connecting hole is Long Circle, and described the second arm is provided with connecting portion.During use, promote con-rod only and be rotatably connected on pedestal by shaft hole, catch bar and connecting hole are hinged, and connecting portion and pushing piece are hinged, and pushing piece is connected with movable contact spring; To drive the first arm motion during the catch bar motion, promoting con-rod only is rotated with it, thereby second connecting portion on arm will drive the pushing piece motion, thereby drive movable contact spring, owing to promoting con-rod only and catch bar, be hinged, it is also hinged promoting con-rod only and pushing piece, thereby it is smoother to move, impulsive force is little, use more reliable, and connecting hole is Long Circle, thereby catch bar has certain headspace while coordinating with connecting hole, makes the impact resistance that promotes con-rod only stronger.
Angle between the first arm described in the utility model and the second arm is obtuse angle.Make structural strength larger.
Angle between the first arm described in the utility model and the second arm is that 120 degree are to 175 degree.
Promotion con-rod only described in the utility model is the integral type structure.Make easy to process.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, owing to promoting con-rod only and catch bar, be hinged, it is also hinged promoting con-rod only and pushing piece, thereby it is smoother to move, impulsive force is little, uses more reliably, and connecting hole is Long Circle, thereby there is certain headspace during the coordinating of catch bar and connecting hole, make the impact resistance that promotes con-rod only stronger.
The accompanying drawing explanation
Fig. 1 is for the structural representation of the promotion connecting rod of direct-acting magnet latching relay in the utility model.
Fig. 2 is for the use state diagram of the promotion connecting rod of direct-acting magnet latching relay in the utility model.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 2, the connecting rod of the promotion for the direct-acting magnet latching relay in the present embodiment comprises promotion con-rod only 1, shaft hole 2, the first arm 3, the second arm 4, connecting hole 5, connecting portion 6, pedestal 7, catch bar 8, pushing piece 9 and movable contact spring 10.
Promote con-rod only 1 in the present embodiment and be provided with shaft hole 2, shaft hole 2 is positioned at the middle part that promotes con-rod only 1, and the two ends of promotion con-rod only 1 are provided with the first arm 3 and the second arm 4, the first arms 3 are provided with connecting hole 5, this connecting hole 5 is Long Circle, and the second arm 4 is provided with connecting portion 6.
Angle a in the present embodiment between the first arm 3 and the second arm 4 is obtuse angle, is preferably 120 degree to 175 degree, and in the present embodiment, a is 165 degree.
Promoting con-rod only 1 in the present embodiment is the integral type structure, makes easy to processly, is beneficial to batch production.
During use, promote con-rod only 1 and be rotatably connected on pedestal 7 by shaft hole 2, catch bar 8 coordinates with connecting hole 5, and connecting portion 6 is connected with pushing piece 9, and pushing piece 9 is connected with movable contact spring 10; To drive the first arm 3 motions during catch bar 8 motion, promoting con-rod only 1 is rotated with it, thereby second connecting portion 6 on arm 4 will drive pushing piece 9 motions, thereby drive movable contact spring 10, owing to promoting con-rod only 1, with catch bar 8, be hinged, promoting con-rod only 1 is also hinged with pushing piece 9, thereby it is smoother to move, impulsive force is little, use more reliable, and connecting hole 5 is Long Circle, thereby catch bar 8 has certain headspace while coordinating with connecting hole 5, makes the impact resistance that promotes con-rod only 1 stronger.
In addition, it should be noted that, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification is only to the explanation of the utility model structure example.Allly according to the utility model patent, conceive equivalence variation or the simple change that described structure, feature and principle are done, be included in the protection range of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection range of the present utility model.
