For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The direction that the utility model is mentioned and position term, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " top ", " bottom ", " side " etc., be only the direction with reference to accompanying drawing or position.Therefore, the direction of use and position term are in order to illustrate and to understand the utility model, but not the restriction to the utility model protection range.
As shown in Figure 1, in the utility model embodiment, being a kind of action bars for laying overvoltage protection device, comprising insulating bar 1, push rod 2, fixing gold utensil 3 and protector fixture 4; Wherein,
One end and the insulating bar 1 of push rod 2 fix, and the other end are formed with a pushing portion 21, and are formed on the outer surface between two ends and be coated with the externally threaded of certain length and tighten portion 22;
One end of fixing gold utensil 3 is formed with a screwed hole matched with the portion of tightening 22, the other end is formed with one for the installation position of installation protector fixture 4, and between two ends, is being formed with a cavity 31; Wherein, the pushing portion 21 of push rod 2 is positioned at cavity 31, and tightens portion 22 and to insert in screwed hole and to be threaded with screwed hole;
Protector fixture 4 comprises two tong arms 41, and each tong arm 41 is all hinged on the installation position of fixing gold utensil 2, and is all positioned at cavity 31 towards one end of insulating bar 1 and leans with the sidewall of pushing portion 21.
In the utility model embodiment, in order to improve the fail safe of action bars, insulating bar 1 is elongated epoxy rods, and the pushing portion 21 of push rod 2 is made by plastic material, and two tong arms 41 are also made by plastic material.Be understandable that, in order to robustness and the reliability of action bars, the portion of tightening of push rod 2 is stainless steel screw rod, and one end and the insulating bar 1 of tightening portion 22 fix.Fixing gold utensil 3 is a stainless steel rectangular frame, and the space in rectangle frame is the cavity 31 for push rod 2 activity.It should be noted that be connected with the portion of tightening 22 diameter held of the pushing portion 21 of push rod 2 should be greater than the diameter of fixing gold utensil 3 screwed hole, push rod 2 can be avoided like this to come off from fixing gold utensil 3.
Meanwhile, comprise two stressed angles upwards opening or formed between closed two tong arms 41 of tong arm 41 for the ease of protector fixture 4, each tong arm 41 is all hinged on by hinge post 32 on the installation position of fixing gold utensil 2.It should be noted that the direction of stressed to be upwards two tong arms 41 the be stressed insulating bar dorsad 1 of two tong arms 41.
Screw thread due to the screw rod of push rod 2 and the screwed hole of fixing gold utensil 3 has the structure of two kinds of different structures, make to there are two kinds of motion modes matched between push rod 2 with fixing gold utensil 3, therefore different from the flexible also corresponding existence two kinds of insulating bar 1 that push rod 2 is connected modes.
First kind of way is: when insulating bar 1 turns clockwise, pushing portion 21 moves towards protector fixture 4 direction in cavity 31, the angle that two of protector fixture 4 tong arms 41 are formed towards insulating bar 1 direction increases gradually, now for fixing and clamping overvoltage protection device; When insulating bar 1 is rotated counterclockwise, pushing portion 21 deviates from the motion of protector fixture 4 direction in cavity 31, and the angle that two of protector fixture 4 tong arms 41 are formed towards insulating bar 1 direction reduces, gradually now for unclamping overvoltage protection device.
The second way is: when insulating bar 1 is rotated counterclockwise, pushing portion 21 moves towards protector fixture 4 direction in cavity 31, the angle that two of protector fixture 4 tong arms 41 are formed towards insulating bar 1 direction increases gradually, now for fixing and clamping overvoltage protection device; When insulating bar 1 turns clockwise, pushing portion 21 deviates from the motion of protector fixture 4 direction in cavity 31, and the angle that two of protector fixture 4 tong arms 41 are formed towards insulating bar 1 direction reduces, gradually now for unclamping overvoltage protection device.
In order to reach laborsaving and open fast or the object of two tong arms 41 of closed protector fixture 4, therefore designing pushing portion 21 is a cone, and each tong arm 41 all leans with the conical surface of cone towards one end of insulating bar 1.
Position in order to avoid overvoltage protection device installation is too high and action bars cannot operate; therefore the length extending action bars is needed; this action bars is provided with the connector 5 be made by stainless steel; for connecting other insulating bar 1; this connector 5 is all arranged at one end that insulating bar 1 deviates from push rod 2; one end of this connector 5 is latch, and the other end is the annulus with shaggy tooth, for fixing between mutually insulated bar 1.
The operation principle of the action bars for laying overvoltage protection device that the utility model provides is rotating insulated bar 1; push rod 2 moves in the cavity 31 of fixing gold utensil 3; two tong arms 41 making the pushing portion 21 of push rod 2 can promote protector fixture 4 upwards open or close; and by the portion of tightening 22, the angle of two tong arms 41 is fixed; reach the object of fixing or unclamping external object, thus carry out charged installation and removal overvoltage protection device.
Implement the utility model embodiment, there is following beneficial effect:
1, in the utility model embodiment, pushing portion due to push rod is centrum, the portion of tightening is stainless steel screw rod, when insulating bar is by when (or counterclockwise) rotates clockwise, push rod is towards protector square fixture to motion, the angle of outwards (namely dorsad insulating bar direction) diminishes fast to make protector fixture, thus clamp and fix external object (as overvoltage device) and do not loosen, when insulating bar is by when (or clockwise) rotates counterclockwise, push rod deviates from protector square fixture to motion, the angle of protector fixture inside (namely towards insulating bar direction) is diminished fast, thus unclamp external object (as overvoltage protection device), therefore this operation lever structure is simple, practical, easy to use
2, in the utility model embodiment, because insulating bar is elongated epoxy rods, and each tong arm of protector fixture is made by plastic material, and therefore this action bars fail safe is high.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
