Abstract
The utility model relates to an auxiliary grounding unit of an isolating switch. A door spindle sleeve is fixed on a door body; a handle spindle is assembled on the axial part of the door spindle sleeve; a gear is fixed on the handle spindle located in the door body and engaged with a rack fixed on a sleeve; the sleeve is slidingly sleeved on a guide shaft fixed on the door body; a contact pin holder on which contact pins are assembled is fixed on one end of the sleeve of the guide shaft; and a pin insertion base provided with contact pin holes is fixed on the door body on the side of the contact pin holder. The auxiliary grounding unit, the whole structure of which is simple and the design of which is reliable, can effectively resolve the grounding problem of the feeding type isolating switch, thus eliminating potential safety hazards, increasing the safety coefficient, ensuring unelectrified shift and achieving the purpose of protecting a load side.
Description
Technical field
The utility model relates to the mine flameproof and intrinsic safety type unit switch, especially a kind of isolating switch auxiliary earth device.
Background technology
The isolating switch of mine flameproof and intrinsic safety type unit switch traditionally generally adopts mechanical type, and its volume is comparatively huge, and structure is comparatively complicated.Along with development of science and technology, isolating switch adopts advanced feeding classification to substitute traditional mechanical type, and the isolating switch of this feeding classification adopts the feed vacuum tube, not charged because of vacuum tube generation electric leakage in order to guarantee the isolating switch load side, isolating switch must be with its ground connection to guarantee the safety of load-side when open position; That is to say that the isolating switch of this feeding classification must adopt ground protection, otherwise can cause security incident.And at present, the isolating switch of feeding classification is not provided with ground connection basically, has stayed potential safety hazard for this reason.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, good reliability, isolating switch auxiliary earth device that security performance is good are provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of isolating switch auxiliary earth device, it is characterized in that: on the door body, be fixed with a door-hinge cover, the axis part of this door-hinge cover is equipped with arbor on the other hand, be fixed with a gear on the Handle axis in the door body, this gears engaged one is packed in the tooth bar that overcoat installed of the suit that the axis of guide slides on the body, one end of axis of guide overcoat is fixed with a stylus holder that contact pilotage is installed on it, is being fixed with a Plug pin patch bay that is shaped on contact pin holes on it on the door body of this stylus holder side.
And described Handle axis is fixed with one handle at the external one handle seat that is installed with of door on this handle set.
And, on Plug pin patch bay with in made three contact pin holes in three corresponding positions of contact pilotage, all draw an earth connection.
Advantage of the present utility model and beneficial effect are:
1. this isolating switch auxiliary earth device has been realized the ground connection of feed-type isolating switch, moves change thereby reached the top, makes and moves the variation lock, guarantees to move to become uncharged purpose, and makes isolating switch play the effect of protection load side when open position.
2. this isolating switch auxiliary earth device overall structure is simple, and design science is reasonable, good reliability; can effectively solve the problem with grounding of feed type isolating switch, eliminate potential safety hazard, improve coefficient of safety; it is not charged to guarantee to move change, reaches the purpose of protection load side.

Fig. 2 is the vertical view (broken section) of Fig. 1.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of isolating switch auxiliary earth device, be installed on the body 13, be fixed with a door-hinge cover 7 on the door body, the axis part of this door-hinge cover is equipped with a Handle axis 8, this Handle axis is installed with a handle set 14 in that door is external, is fixed with a handle 15 on this handle set.Be fixed with a gear 9 on the Handle axis in the door body.
Laterally be fixed with an axis of guide 4 at the door below this gear on the body, an end of this axis of guide is packed on the mounting panel 12, and this mounting panel and door body adopt a screw (among the figure not label) to install; The other end of this axis of guide is packed on the Plug pin patch bay 1, and this Plug pin patch bay adopts the screw mode to be packed on the body equally.
The axis of guide is slidingly fitted with an overcoat 11, is fixed with a tooth bar 10 in that the top of this overcoat outer rim is coaxial, and this tooth bar can be meshed with gear.
The position of closing on Plug pin patch bay at the axis of guide radially is fixed with a stylus holder 6 on the coat, and the coaxial arrangement pitch of this stylus holder is equipped with three contact pilotages 5.
Be shaped on three contact pin holes 3 with three corresponding positions of contact pilotage on Plug pin patch bay, these three contact pin holes are all drawn earth connection 2.
Operation principle of the present utility model is:
The rotary isolation switch handle, then Handle axis radially rotatablely moves together with gear, by the engagement of rack-and-pinion, rotatablely moving of gear is transformed into the horizontal transmission of tooth bar, thereby tooth bar left and right sides straight line on the axis of guide is moved.Because tooth bar is packed in the outer of the axis of guide and puts, so the stylus holder that installs is on the coat also done rectilinear motion, the contact pilotage that is installed on it can insert in the contact pin holes, is grounded.
Claims (3)
1. isolating switch auxiliary earth device, it is characterized in that: on the door body, be fixed with a door-hinge cover, the axis part of this door-hinge cover is equipped with arbor on the other hand, be fixed with a gear on the Handle axis in the door body, this gears engaged one is packed in the tooth bar that overcoat installed of the suit that the axis of guide slides on the body, one end of axis of guide overcoat is fixed with a stylus holder that contact pilotage is installed on it, is being fixed with a Plug pin patch bay that is shaped on contact pin holes on it on the door body of this stylus holder side.
2. isolating switch auxiliary earth device according to claim 1 is characterized in that: described Handle axis is fixed with one handle at the external one handle seat that is installed with of door on this handle set.
3. isolating switch auxiliary earth device according to claim 1 is characterized in that: all draw an earth connection on Plug pin patch bay with in made three contact pin holes in three corresponding positions of contact pilotage.
