Description
Technical field
The utility model relates to a kind of electrical bar terminal box, particularly a kind of high-intensity sealing structure of electrical bar terminal box.
Background technology
Electrical bar is a kind of electric elements converting electrical energy into heat energy specially, due to its low price, easy to use, installs simple, and is widely used in various heating occasion.As shown in Figure 1, electrical bar generally includes eduction rod and terminal box two parts, and terminal box is by junction block, rubber blanket, base and metal cover board; Wherein, eduction rod is drawn from junction block, its top is connected with terminals, metal cover board is arranged on the top of junction block, in the bottom of junction block, rubber blanket is housed, mounting seat bottom rubber blanket, screw is through metal cover board, junction block and base, last bottom is fixed by nut, thus locking eduction rod and the space be connected between pedestal, reach the effect of sealing.
But, existing this electrical bar terminal box sealing hermetically-sealed construction, its top metal cover plate is the iron plate that middle part is provided with the plane of square openings, when Long-Time Service, finds the lengthening along with service time, can follow the string and permanent deformation occurs in the corner of metal cover board under the long-term extruding of screw, its square openings edge can be upturned, and causes hold-down screw to loosen, thus has destroyed afterwards overall hermetically-sealed construction, cause terminals to be intake and short circuit or serious aging, break down.This not only greatly reduces the useful life of product, time serious, even can endanger the personal safety of user.
Utility model content
The purpose of this utility model is: the high-intensity sealing structure proposing a kind of electrical bar terminal box, and it can greatly delay and reduce the problem of the terminal box seal failure caused due to metal cover board distortion.
The utility model solves the technical scheme that its technical problem adopts:
A high-intensity sealing structure for electrical bar terminal box, comprises metal cover board, nylon base, base, trip bolt and rubber sleeve, described metal cover board covers on described nylon base, described nylon base is placed on described base, described rubber sleeve is enclosed within the bottom of described nylon base, be placed between described base and described nylon base, it is characterized in that, described metal cover board is in square, a circular open is provided with in the middle part of it, the outer of this metal cover board is provided with flange under a circle, in the middle part of it, circular open place is provided with a circle upper overturning, four corners of described metal cover board are all provided with a screw respectively, described trip bolt is each passed through described metal cover board and described nylon base, and described metal cover board is locked on described base.
Further, the lower flange of described metal cover board and the outer wall of described nylon base fit tightly.
Further, the top middle portion of described nylon base is provided with the terminals of a projection, and described terminals are cylindrical.
Further, the size of the circular open in the middle part of described metal cover board and described terminals adapts, and described metal cover board is enclosed within described terminals, and the outer wall of its upper overturning and described terminals fits tightly.
Further, the inwall of described rubber sleeve and the bottom outer wall of described nylon base fit tightly.
The beneficial effects of the utility model are: the utility model structure is simple, with low cost, and adopt scheme of the present utility model can greatly delay and reduce the distortion of metal cover board, thus reach better, more lasting sealing effectiveness.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of the utility model metal cover board.
In figure: 1-metal cover board, 2-nylon base, 3-base, 4-trip bolt, 5-rubber sleeve, 6-inner bag, 7-eduction rod, 8-terminals, 9-water; 11-screw, 12-circular open.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In order to clearly show overall structure of the present utility model, figure 1 shows the sectional structure of the utility model one jiao, show in figure, the utility model comprises metal cover board 1, nylon base 2, base 3, trip bolt 4, rubber sleeve 5; Wherein, metal cover board 1 covers on nylon base 2, and nylon base 2 is placed on base 3, and rubber sleeve 5 is enclosed within the bottom of nylon base 2, and is placed between base 3 and nylon base 2; Trip bolt 4 is each passed through metal cover board 1 and nylon base 2, and is locked on base 3 by metal cover board 1.
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, the concrete structure of detailed annotation explanation metal cover board 1.
Accompanying drawing 2 shows the face of overlooking of metal cover board 1 in square, and its four corners are all respectively equipped with a screw 11, are provided with a circular open 12 in the middle; Again by reference to the accompanying drawings 1, the outer of known metal cover board 1 is provided with flange under a circle, and in the middle part of it, circular open place is provided with a circle upper overturning.
In addition, it can also be seen that in accompanying drawing 1, the top middle portion of nylon base 2 is provided with the terminals 8 of a projection, these terminals 8 are cylindrical, and the circular open 12 in the middle part of metal cover board adapts with the size of terminals 8, metal cover board 1 is enclosed within terminals 8, and the outer wall of its upper overturning and terminals 8 fits tightly.
Preferably, the inwall of rubber sleeve 5 and the bottom outer wall of nylon base fit tightly.
