Detailed description of the invention
Fig. 1 is schematic cross-sectional view of the present invention；
Wherein, ontology 100, inlet wire slot 110, ejector pin slot 120, adjustment pin slot 130, ejector pin 200, pressing plate 210, vertebra
First 220, adjustment pin 300, pinion gear 310, compressed spring 400, shaft 500, gear wheel 510, knob 511, fuse 600.
Specific embodiment
It elaborates below in conjunction with specific embodiment to the present invention.
The present embodiment is as shown in Figure 1, include ontology 100, ejector pin 200, adjustment pin 300 and compressed spring 400.Ontology 100
One end be equipped with strip inlet wire slot 110, the aperture of inlet wire slot 110 should be slightly larger than 600 diameter of fuse.The phase at the end
Neighboring terminal is equipped with ejector pin slot 120 that is vertical and crossing inlet wire slot 110, and the opening of ejector pin slot 120 is nearby equipped with adjusting cotter way
Hole 130, the diameter of adjustment pin slot 130 should be slightly larger than the diameter of adjustment pin 300.Ejector pin slot is inserted into one end of ejector pin 200
120, the other end of ejector pin 200 is equipped with pressing plate 210, and pressing plate 210 is equipped with threaded hole.Adjustment pin 300 is equipped with corresponding with threaded hole
Screw thread, one end of adjustment pin 300 passes through threaded hole and is inserted into adjustment pin slot 130.One end of compressed spring 400 is detachably fixed
On pressing plate 210, the other end of compressed spring 400 is detachably secured on ontology 100, the other end of certain compressed spring 400
It is preferably fixed directly on the end face at 100 ejector pin slot 120 of ontology opening place.When compressed spring 400 in the raw when,
The end face that ejector pin 200 is inserted into ejector pin slot 120 is located in inlet wire slot 110 or passes across inlet wire slot 110.
The use of above structure and principle process are as follows:
The pulling force of compressed spring 400 is overcome to pull pressing plate 210 on the other hand, the end face for making ejector pin 200 be inserted into ejector pin slot 120 is remote
From inlet wire slot 110, inlet wire slot 110 is inserted into one end of fuse 600 by another hand, then unclamps pressing plate 210, pressing plate
210 end faces for promoting ejector pin 200 to be inserted into ejector pin slot 120 under the action of 400 power of compressed spring resist fuse 600, make to protect
Dangerous silk 600 deforms in the end of inlet wire slot 110, so that fuse 600 be made to be locked in ontology 100.When needing to adjust
When saving ejector pin 200 to 600 pressure size of fuse, adjustment pin 300 need to be only turned, is changed between pressing plate 210 and ontology 100
Distance.
Structure of the invention has multiple beneficial effect, these types is included at least, first, fuse 600 can be locked, and energy
Guarantee that the coupling mechanism force of fuse 600 under work condition state is kept constant, contact is reliable；Second, the coupling mechanism force of fuse 600 is adjustable,
Energy limited containment is solved because of related accidents such as the excessively thermally-induced fire of 600 poor contact scaling loss of fuse or contact point because of insurance
600 connecting terminal screw thread scaling loss rear terminal Problem of Failure of silk；Third, operation of the present invention is convenient, it can be more without tool after operating a switch
Insurance is changed, device to hole alignment issues are more not present in the present invention, and foolproof installation is easily quick；Even if fourth, because of operating reason or
Person's fuse 600 fuses in ontology 100, and structure of the invention designs the extremely convenient taking-up so that fuse 600 breaks end；Its
Five, the present invention it is easy to disassemble, facilitate maintenance, even if fuse 600 break end stick inner body wall can also by way of disassembly incite somebody to action
It takes out.
It should be noted that the opposite end of 100 inlet wire slot 110 of ontology is wire connecting ends, also do not indicated in Fig. 1,
But it will be understood by those skilled in the art that is not described herein.
Preferably, the number of adjustment pin 300 is two or more, and adjustment pin 300 is uniformly distributed around the axis of ejector pin 200
Distribution.The setting of multiple adjustment pins 300 can be such that the force of this structure and stress more balances with rationally, make ejector pin 200 in ejector pin
Sliding and adjustment pin 300 are slided in adjustment pin slot 130 and will not be deflected in slot 120, can effectively prevent ejector pin 200
The fluency that either ejector pin 200 was blocked and improved to adjustment pin 300 or adjustment pin 300 is slided；Secondly, this set needs to correspond to
More compressed springs 400 are added, further increase ejector pin 200 to the pressing force of fuse 600.
Preferably, the other end of adjustment pin 300 is equipped with pinion gear 310.It further include shaft 500, one end rotation of shaft 500
It is fixed on pressing plate 210, the other end of shaft 500 is equipped with gear wheel 510, and gear wheel 510 is engaged with pinion gear 310.It is this to set
It sets so that need to only rotate gear wheel 510, pinion gear 310 can be driven to rotate synchronously, so that adjustment pin 300 be driven to rotate, play
Change the effect of distance between pressing plate 210 and ontology 100.This set includes multiple beneficial effect, firstly, need to only be rotated
This operation of gear wheel 510 can adjust multiple adjustment pins 300 simultaneously, optimize operating procedure；Secondly, multiple pinion gears
310 are able to achieve synchronous rotation, are consistent the regulated quantity of multiple adjustment pins 300, avoid and adjust the easily production of adjustment pin 300 by several times
Raw regulated quantity inconsistence problems are not in that the inclination of pressing plate 210 causes ejector pin 200 or adjustment pin 300 to block problem.As
It advanced optimizes, the knob 511 of isolation material can also be equipped in the end face of gear wheel 510, facilitate rotation process.
Preferably, shaft 500 and pressing plate 210 rotate bearing equipped with torsional spring, and torsional spring can be used for clamping gear wheel 510, make
Gear wheel 510 does not rotate easily, caused by preventing its shaking or uncertain factor from gear wheel 510 being caused independently to rotate
Fuse 600 loosens.In fact, torsional spring also further increases ejector pin 200 to fuse while clamping gear wheel 510
600 pressing force.
Preferably, it is cone cell that adjustment pin 300, which is inserted into the end of 200 slot 120 of ejector pin, is spherical, vertebra head at vertebra head 220
220 radius is be inserted into 600 radius of fuse 1/3~2/3.It is got, is led to by many experiments when 1/3~2/3 this data
It crosses experiment to learn, 220 radius of vertebra head is opposite easily to break fuse 600 into 600 radius of fuse is too small, and 220 radius of vertebra head is opposite
It is too small into the excessive deflection for easily leading to fuse 600 of 600 radius of fuse, do not have the effect blocked.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
