The specific embodiment
Briefly say; The utility model discloses a kind of fuel tank protective cover that is used for the crawler crane fuel tank; This protective cover comprise the base. member that is used for fixing predetermined position to the said fuel tank and with base. member pivotly bonded assembly, be used to block the block piece of fuel tank locking cap; Be provided with bias voltage or inclined to one side draw piece between said base. member and the said block piece; Be fixed under the state on the said fuel tank in said base. member, said block piece is in the position of blocking of blocking fuel tank locking cap inlet, and said block piece opened by pivot and away from said block the position when moving said bias voltage or partially draw piece said block piece is blocked the position bias voltage or draws partially to said.
A nonrestrictive embodiment below in conjunction with shown in the accompanying drawing describes the utility model.What need special version here is, diagramatic content only is exemplary, and those skilled in the art should be able to obviously predict other alternative characteristics and scheme after having read the utility model.
Particularly, in the illustrative embodiments shown in Fig. 1-Fig. 3, the predetermined position that will be installed on fuel tank 20 according to the protective cover 10 of the utility model is for example on the fuel tank locking cap 21 (for example referring to Fig. 2,3).In Fig. 1, said protective cover 10 is in the position of blocking of blocking fuel tank locking cap 21.The block piece 12 that Fig. 2 shows said protective cover 10 is opened and away from the said situation of position when moving of blocking.
The formation of protective cover 10 is at first described below.
In the illustrated embodiment; Like Fig. 2, shown in 3, this protective cover 10 comprise the base. member 11 that is used for fixing predetermined position (for example fuel tank locking cap main part) to the said fuel tank and with base. member 11 can pivot bonded assembly, be used to block the block piece 12 of fuel tank locking cap.
In graphic illustrative embodiments, as shown in Figures 2 and 3, base. member 11 is assembled together through being connected pin 13 with said block piece 12 pivotly.Particularly, said block piece 12 is provided with duct 14 separately with said base. member 11, and said block piece is connected via the pin that passes said duct 14 13 with said base. member pivotly.In the situation shown in Fig. 3, said duct 14 is provided by the additional member (for example crooked sheetmetal) that is connected to respectively on said block piece 12 and the said base. member 11.Those skilled in the art will be understood that except by pin, also have a lot of other known modes to realize that base. member 11 is connected with pivoting of block piece 12.
In addition, for realize block piece from reset function, between said base. member 11 and said block piece 12, also be provided with bias voltage or draw piece partially.
In the illustrated embodiment, like Fig. 3-shown in Figure 5, said bias voltage or partially draw piece be a coil spring 16.But those skilled in the art should understand, and the sheet leaf spring that bias voltage that other are suitable or inclined to one side draw piece for example are bent into U-shaped or V-arrangement also can be used for the utility model.Further, other bias voltages well known in the prior art or inclined to one side pull mechanism also can be used for the utility model.
To bias voltage or the situation when partially draw piece is coil spring 16; According to the utility model; First end of said coil spring 16 (for example 161) will be connected in said base. member 11 and the said block piece 12, and the second opposed end of coil spring 16 (for example 162) is connected to another in said base. member 11 and the said block piece 12.According to an aspect of the utility model, the part of said pin is exposed outside, and helical spring main body is enclosed within on the exposed part of said pin.
Especially, under relaxed state, be formed with predetermined angle between first end of said coil spring 16 and second end.More specifically; When said helical spring axis is observed; Form a predetermined angle between said first end and second end, in embodiment shown in Figure 4, said angle is 90 degree; But those skilled in the art should understand, and also are fine less than the angle of 90 degree or other suitable angle.
By such as the draw piece of helical spring bias voltage/partially, will there be balance position between said block piece and the said base. member corresponding to bias voltage/when draw piece is not worked (promptly not producing inclined to one side power) partially, have a predetermined angle between two parts at this moment.Under the external force effect of the inclined to one side power that is overcoming bias voltage/inclined to one side draw piece; In said block piece and the said base. member one begins (promptly beginning from said predetermined angle) when further pivoting each other (when angle becomes big) with respect to another by said balance position with opening; Said bias voltage/partially draw piece will do work, and makes a said generation in said block piece and the said base. member to the automatically reset trend of said balance position.Like this, when said external force was removed, said one in said block piece and the said base. member will reset under bias voltage/inclined to one side draw piece effect.
Thus; Parameters such as size through suitable each parts of design; Can realize the situation shown in figure; That is: when said base. member 11 is fixed in suitable position on the fuel tank (for example being set on the fuel tank locking cap main body), said block piece 12 can cover the end of fuel tank locking cap, and this moment, bias voltage/draw piece possibly not be out of shape partially; Perhaps only little distortion is arranged and make block piece, even if can operating personal forget that covering fuel tank locking cap so also can isolate extraneous burning things which may cause a fire disaster and get in the fuel tank against the end of said fuel tank locking cap; And in the time will refueling, operating personal can start said block piece 12, and at this moment, bias voltage/draw piece will be out of shape acting partially, and protective cover is opened simultaneously, shown in accompanying drawing 2; After adding diesel oil; Operating personal can cover fuel tank locking cap; Subsequently, the block piece of protective cover down will auto-closing in the effect of the draw piece of bias voltage/partially, thereby plays the effect of protection isolation burning things which may cause a fire disaster; Even if operating personal is forgotten the safety that also can prevent diesel fuel tanks when closing fuel tank locking cap, the generation that thoroughly eliminates danger from the source after refueling.
According to an aspect of the utility model, as shown in Figure 3, said fuel tank locking cap 21 comprises from the outstanding main part 211 of the main body of fuel tank.The base. member 11 of said protective cover 10 has the sleeve part 111 that can be locked on the main part 211 of said fuel tank locking cap.Another aspect according to the utility model; The base. member 11 of said protective cover comprises two sections arched members; Two ends of every section arched member are provided with tapped bore; Two sections arched members can clip on relative two cylindrical side of the main part 211 of said fuel tank locking cap, and by the screw element at the two ends of passing two sections arched members and be fastened on the said main part 211.According to another aspect of the utility model, said base. member is not to be locked on fuel tank locking cap, but can be bonded to the plate-like piece on the tank wall of fuel tank.
In addition, those skilled in the art should understand, and the shape and size of block piece 12 etc. do not have concrete restriction, as long as the end that when said base. member is installed on the said fuel tank, can block fuel tank locking cap.In a nonrestrictive embodiment, said block piece 12 can block the plate-like piece of the end of said fuel tank locking cap 21 for its size.
