Lotus switch is protected.When assembly, mounting flange is welded on oil tank wall, tank wall flange is matched with fuse mounting flange, fusing
Device shell is structure as a whole with fuse mounting flange, and fusible core of fuse is connected through a screw thread with fusible core bracket and is integrated.Fusing
After the assembly is completed, fusible core of fuse and fusible core bracket are inserted into fuse enclosure interior to device shell, are fastened on fusing by external screw thread
On device shell, assembly is completed.
The structure during normal use, has no problem substantially.But under the conditions of some specific, because calculating the originals such as deviation
Cause can make the ampere-time characteristic of fusible core of fuse and higher level's protection fail intact matching, cause fusible core in fusing, fuse housing
Internal pressure abruptly increase, sharply generates heat and fusible core of fuse and fusible core bracket is made to break through the externally threaded coupling mechanism force of fuse,
It is produced out of shell.Such as extraneous suitable condition, the risk for causing secondary disaster will be generated.
Summary of the invention:
The present invention be in order to solve the above-mentioned problems of the prior art and to provide a kind of anti-high pressure gamut protection current limliting molten
Disconnected device fusible core produces structure.
The technical solution adopted in the present invention has: a kind of anti-high pressure gamut protection produces knot with limiting fuse fusible core
Structure, including fuse and fuel tank, the fuse include fuse shell, fuse flange, fusible core bracket and fusible core, described molten
Disconnected device shell and fuse flange are integrally formed, and fusible core and fusible core bracket are placed in fuse housing body, and fusible core and fusible core branch
Frame, which is connected through a screw thread, to be integrated, and tank wall flange is equipped on the tank wall of fuel tank, and the tank wall flange is fixed with fuse flange
Connection, further includes shield, the shield is fixedly connected with the fuse flange of fuse；
The shield includes shield fixed plate and installation foot, and the shield fixed plate is circular configuration, several installation feet along
The circumferencial direction of shield fixed plate is arranged, and one end of installation foot is fixedly connected by bolt with shield fixed plate, installation foot and
Fuse flange is fixedly connected.
Further, the installation foot has the ontology of a strip, and 90 ° of bendings are simultaneously in the opposite direction at the both ends of ontology
Form installation side.
Further, the installation side is equipped with mounting hole.
Further, the center point of the shield fixed plate is equipped with through-hole.
Further, there are four installation foot is set.
Further, the tank wall flange is equipped with and is welded with screw rod, and fuse flange and installation foot are connected on screw rod.
The invention has the following beneficial effects:
The producing when present invention effectively prevents fusible core of fuse to fuse improves the safety of product, it is several to reduce accident
Rate.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Fig. 2 is the main view of shield in the present invention.
Fig. 3 is the left view of shield in the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 to Fig. 3, a kind of anti-high pressure gamut protection of the present invention produces structure with limiting fuse fusible core, including molten
Disconnected device 1, fuel tank and shield 3, fuse 1 include fuse shell 11, fuse flange 12, fusible core bracket 13 and fusible core 14,
Fuse shell 11 and fuse flange 12 are integrally formed, and fusible core 14 and fusible core bracket 13 are placed in fuse shell 11, and
Fusible core 14 is connected through a screw thread with fusible core bracket 13 and is integrated, and tank wall flange 21, tank wall flange 21 are equipped on the tank wall of fuel tank
It is fixedly connected with fuse flange 12, shield 3 is fixedly connected with the fuse flange 12 of fuse 1.
Shield 3 includes shield fixed plate 31 and installation foot 32, and shield fixed plate 31 is circular configuration, 4 installation feet 32
It is arranged along the circumferencial direction of shield fixed plate 31, and one end of installation foot 32 connects by the way that bolt and shield fixed plate 31 are fixed
It connects, installation foot 32 is fixedly connected with fuse flange 12.
Installation foot 32 has the ontology 321 of a strip, and the both ends of ontology 321 90 ° of bendings and are formed in the opposite direction
Side 322 is installed, is equipped with mounting hole on installation side 322.
The center point of shield fixed plate 31 is equipped with through-hole 310, which can observe fuse 1, also can be with winding displacement.
It being equipped on tank wall flange 21 and is welded with screw rod 22, fuse flange 12 and installation foot 32 are connected on screw rod 22,
It is threadedly coupled nut on screw rod 22, fuse flange 12, tank wall flange 21 and shield 3 are locked.
The case of scene operation becomes, if removing 4 fastening nuts simultaneously installs shield 3, has from fuse Method for Installation
The risk of blue face oil leak.To adapt to the operating condition, shield 3 is designed as breakdown structure (shield fixed plate 31 and peace by the present invention
Fill foot 32), 31 separate machined of installation foot 32 and shield fixed plate is bolted by 4 sets of M10 and is integral.When assembly, one by one
Fastening nut is dismounted, mounting strap installation foot finally installs shield fixed plate additional.Structure design both solved in assembling process
Oil leak risk in turn simplifies the processing technology of shield, has saved material, while more adapting to large-scale production.
Structure of the invention is used comprehensively, by on-site verification, when effectively fusible core of fuse being prevented to fuse
It produces, improves the safety of product, reduce accident probability.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
