Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Fig. 1 shows according to the master of the embodiment mono-of the block piece of porcelain knob disconnecting link of the present utility model and looks schematic diagram, and Fig. 2 shows the schematic top plan view of the block piece of Fig. 1.As shown in Figure 1 to Figure 2, the block piece of embodiment mono-comprises housing 10 and locking rod 20, offers for holding the spatial accommodation of porcelain knob on housing 10, and this spatial accommodation has opening.Locking rod 20 is rotatably connected on housing 10, and locking rod 20 has the unlocked position that porcelain knob is locked in to the latched position in spatial accommodation and allows porcelain knob turnover spatial accommodation.
The block piece of embodiment mono-is contained in a porcelain knob of porcelain knob disconnecting link in spatial accommodation by housing 10, makes housing 10 be wrapped in the outside of porcelain knob, and can be fixed on porcelain knob by the housing 10 that is arranged so that of locking rod 20, prevents that housing 10 from departing from from porcelain knob.By the parcel of housing 10, porcelain knob is isolated from the outside, the danger that has effectively prevented operating personnel from touching porcelain knob in the process of hot line job by mistake and occurred, thus the work of repairing porcelain knob disconnecting link can chargedly be carried out, avoided repairing because having a power failure the loss causing.
Preferably, on the first side wall, be provided with for connecting the rotating shaft 30 of locking rod 20.Locking rod 20 comprises lever piece and the lock segments being connected with operating side, lock segments is preferably bending section 21, lever piece is preferably along the bending section 21 outward extending straight sections 22 in one end, and the junction of bending section 21 and straight section 22 is set in outside rotating shaft 30, so that locking rod 20 can 30 rotate around the shaft, carry out the conversion between locked.As shown in Figure 2, when locking rod 20 is positioned at unlocked position, straight section 22 blocks the opening part at spatial accommodation, housing 10 is being installed in the process on porcelain knob, in the porcelain knob process that enters into spatial accommodation gradually, porcelain knob can drive straight section 22 30 to rotate around the shaft, thereby makes locking rod 20 along with entering around the shaft of porcelain knob 30 rotated.When porcelain knob enters in spatial accommodation completely, locking rod 20 can move to latched position from unlocked position, and the locking rod 20 that is positioned at latched position coordinates jointly with housing 10, and block piece is fixed on porcelain knob.
When locking rod 20 moves to latched position from unlocked position, straight section 22 can 30 move around the shaft in spatial accommodation, when porcelain knob enters into spatial accommodation to a certain degree time, between the inner surface of the first side wall and straight section 22, can interfere by occurrence positions, the inner surface that is the first side wall can produce and hinder the motion of straight section 22, stops the continuation campaign of straight section 22.In this case, can on the inner surface of the first side wall, the first fluting be set the position of corresponding straight section 22, when straight section 22 is when turning to the first side wall place, can enter in the first fluting, make straight section 22 be positioned at the first inwall, thereby eliminate the location conflicts between straight section 22 and the first side wall.In the time of in straight section 22 moves to the first fluting, locking rod 20 is positioned at latched position.A kind of preferred embodiment in, also the first fluting can be set to the form of breach, under this structure, locking rod 20 can carry out the rotation of 360 ° around rotating shaft 30.Preferably, rotating shaft 30 is arranged in the first fluting, and is positioned at the first side wall away from one end of arcwall.
Similar with the fluting of first on the first side wall, at the second sidewall, away from one end of arcwall, be provided with the second fluting coordinating with locking rod 20, when locking rod 20 is positioned at latched position, the free end that does not connect straight section 22 on bending section 21 is arranged in the second fluting, prevents that between the second side plate and bending section 21, occurrence positions is interfered.Preferably, can between bending section 21 and the second fluting, the spacing measures such as interface arrangment be set, in order to locking rod 20 is limited to latched position.Like this arrange to have prevents that locking rod 20 from departing from unlocked position under the collision of external force, thereby the block piece causing is from the capable disengaging of porcelain knob, loses protection effect.For guaranteeing safety, each material of block piece all should be selected insulation material.
As shown in Figure 1, locking rod 20 is arranged on the top of housing 10, is provided with the diapire 50 of shutoff housing 10 at the place, bottom of housing 10, is equipped with the holding rod 40 of insulation on diapire 50.The block piece of the present embodiment in use, operating personnel hold holding rod 40, make the opening of spatial accommodation towards porcelain knob, block piece is moved to porcelain knob direction, make porcelain knob enter into spatial accommodation, at porcelain knob, move in the process of spatial accommodation, can drive locking rod 20 to move to latched position by unlocked position, block piece is fixed on porcelain knob, porcelain knob is isolated from the outside, prevent that operating personnel from touching porcelain knob in operation mistiming.Preferably, between holding rod 40 and diapire 50, be threaded engagement, so that holding rod 40 can, along the axis direction turnover spatial accommodation of self, hold out against the porcelain knob that is positioned at spatial accommodation.
The master that Fig. 3 shows the embodiment bis-of block piece of the present utility model looks schematic diagram, embodiment bis-is from the different of embodiment mono-, in embodiment bis-, locking rod 20 includes cross section to be the body 23 of U-shaped and to be connected to the locking rod 20 on body 23, wherein, on the wall being oppositely arranged of described body 23, be provided with the first above-mentioned fluting and the second fluting, and be provided with rotating shaft 30 in the first fluting, locking rod 20 consists of above-mentioned straight section 22 and bending section 21.In use, the first end of body 23 is connected on housing 10 locking rod 20 in embodiment bis-, makes body 23 form a part for housing 10.All the other structures of embodiment bis-are identical with embodiment mono-.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
