Description
Technical field
The utility model relates to a kind of knocker, especially relates to a kind of knocker for terminal box of transformer substation chamber door.
Background technology
At present, the terminal box chamber door design of transformer station generally adopts knob knocker, relies on spring to hold zinc-plated buckle, to compress chamber door.But the spring of knob knocker easily produces deformation because of stretching dynamics excessive for a long time, causes pulling force to decline.And, be difficult to the adjustment zinc-plated buckle of knocker and the angle of articulation of door: spring tension is too tight, does not block door; Spring tension is too loose, the not tight door of card.Zinc-plated buckle Chang Yinyu door misplaces and angular distortion, and the situation that card is not in place occurs, and the chamber door caused is closed not tight.
Heavy Rain of Typhoon prone areas directly under the jurisdiction of a municipal government, Maoming, when typhoon weather, because strong wind tears terminal box knob knocker, the chamber door seam that buckle is shifted up and down and angular distortion causes is not tight, and cause the situation into water to happen occasionally, thus produce the potential safety hazard that electric loop short circuit or moist insulation decline, equipment corrosion, DC earthing may be caused time serious, transmit by mistake, disconnecting link refuses point to refuse conjunction, even switch and refuse point to refuse the accidents such as conjunction, mistrip.In addition, each terminal box of transformer station has knocker, and because the few equipment of people is many, the maintenance of knocker is difficult to accomplish to be in time, the spring of knob knocker and the situation of screw corrosion very serious.
Utility model content
Problem to be solved in the utility model, just be to provide a kind of knocker for terminal box of transformer substation chamber door, its buckle and inner spring not easily produce deformation under long-term pulling force effect, easily can adjust the zinc-plated buckle of knocker and the angle of articulation of door, chamber door is tightly closed, and not perishable, do not need frequent maintenance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of knocker for terminal box of transformer substation chamber door, comprise be fixed on chamber door, fixing clasp 1 that surface has convex button and buckle 2, it is characterized in that: described buckle 2 is that a long-armed rear end is fixed on the T-shaped bar formed in the middle of a vertical cross-bar, and long-armed front end has the buttonhole 3 corresponding to described clasp 1; Outside also comprise:
One is fixed on the block knocker base 10 on casing;
Leader 9, and its one end, by fixed pin shaft 7, is hinged on described knocker base 10;
One chute 5 is long frame-like, and rear end is hinged on the elongate slots formation guide rail described handle 9 middle and lower part, front end deckle board having and through hole, both sides deckle board has symmetry;
Described buckle 2 long-armed is through in the deckle board through hole of described chute 5 front end, cross bar two ends, rear end are inserted in the elongate slots of described chute 5 both sides deckle board symmetry to be formed and are slidably connected, and long-armed between described chute 5 front end deckle board and buckle 2 rear end cross bar is provided with Compress Spring.
Beneficial effect: the spring of a kind of knocker inside for terminal box of transformer substation chamber door of the present utility model not easily produces deformation under long-term pulling force effect, the design of Straight pull avoids the angular distortion of knob buckle and is shifted up and down and causes the phenomenon got loose.Memorial alloy for making knocker not easily gets rusty, and can return to the original form after distortion, therefore can not cause fracture because buckle self suffers repeatedly to bend.It does not need frequent maintenance, can close imprecision present situation by solution chamber door in essence ground.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of knocker for terminal box of transformer substation chamber door of the present utility model;
Reference numeral: 1-fixes clasp; 2-buckle; 3-buttonhole; 4-spring; 5-chute; 6-chute guide rail; 7-fixed pin shaft; 8-bearing pin; 9-handle; 10-knocker base.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
A kind of knocker for terminal box of transformer substation chamber door, comprise be fixed on chamber door, fixing clasp 1 that surface has convex button and buckle 2, it is characterized in that: described buckle 2 is that a long-armed rear end is fixed on the T-shaped bar formed in the middle of a vertical cross-bar, and long-armed front end has the buttonhole 3 corresponding to described clasp 1; Outside also comprise:
One is fixed on the block knocker base 10 on casing;
Leader 9, and its one end, by fixed pin shaft 7, is hinged on described knocker base 10;
One chute 5 is long frame-like, and rear end is hinged on the elongate slots formation guide rail described handle 9 middle and lower part, front end deckle board having and through hole, both sides deckle board has symmetry;
Described buckle 2 long-armed is through in the deckle board through hole of described chute 5 front end, cross bar two ends, rear end are inserted in the elongate slots of described chute 5 both sides deckle board symmetry to be formed and are slidably connected, and long-armed between described chute 5 front end deckle board and buckle 2 rear end cross bar is provided with Compress Spring.
When the fastening knocker for terminal box of transformer substation chamber door of the present utility model, first the convex button on fixing clasp 1 blocks the buttonhole 3 on buckle 2.Then, near the direction of casing pushing handle 9, make it make circular arc with fixed pin shaft 7 for axle and rotate, and drive chute 5 by the rotation of bearing pin 8 in the process.Chute 5 and buckle 2 relative motion along chute guide rail 6 moving linearly, make spring 5 inwardly compress.When handle 9 becomes level with buckle 2 angle, the compression of fixing clasp 1 can be realized.When unclamping knocker of the present utility model, first to the direction push handle 9 away from casing, make it make circular arc with fixed pin shaft 7 for axle and rotate, and drive chute 5 by the rotation of bearing pin 8, thus drive the motion of buckle 2, make buttonhole 3 leave raised structures on fixing clasp 1.
Because buckle 2 can only make linear running along chute guide rail 6, can prevent buckle 2 angular distortion from getting loose.The length of chute guide rail 6 determines the Tension and Compression length of spring 4, and therefore, spring 4 can not block not tight because stretching dynamics is too little, also spring 4 will be caused to restore because compression stress spends large.
