Description
Technical field
The utility model relates to box body structure design field, particularly a kind of is applied in various types of box body structure being made up of upper cover and base, connects upper cover and base to ensure the structure of box body sealing reliability by sealing-ring form.
Background technology
The application scenario of the various box bodies comprising terminal box comprises the environment such as open air, sleet, dust, therefore prevents outside medium from infiltrating terminal box inside thus affecting the electrical connection of terminal box inside, is an important Consideration in design.
In the design of Sealing Structure of existing terminal box, the sealing between upper cover and base is undertaken sealing by upper cover and base extruding rubber seal between the two. Rubber seal is installed in the groove body of upper cover, and the block other by means of only groove body blocks to be unlikely to come off. But this kind of sealing means has following shortcoming:
1, block is limited to the fixed effect of sealing-ring, and sealing-ring easily comes off;
2, the upper cover thickness at sealing-ring place place is less, and intensity is lower;
3, rubber seal need to accomplish just can be stuck in groove body with groove body width about the same, block extruding rubber seal, and rubber seal is easily out of shape aging, affects the life-span;
4, rubber seal also extrudes upper cover, and the easy stress deformation of upper cover causes poor sealing;
5, sealing-ring and base inside do not have heat isolation, and the heat that box body internal components sends easily is transmitted on sealing-ring, affects the life-span of sealing-ring;
6, sealing-ring and base inside do not have electromagnetic isolation, charged apart from little between human body and the internally charged device of box body, easily cause various short circuit, fire and explosion hazard.
Practical novel content
For the above-mentioned shortcoming of existing box body sealed structure, applicant, through Improvement, now provides a kind of physical strength height, good seal performance, sealing-ring to be not easily out of shape and sealing-ring and box body internal components can keep the box body sealed structure of isolation.
The technical solution of the utility model is as follows:
A kind of box body sealed structure, comprises base, upper cover and sealing-ring; The top of base is provided with a ring annular groove, and the part of base in the inside and outside both sides of annular recesses be the inwall of looping groove and the outer wall of annular recesses respectively, and the top of the outer wall of annular recesses is provided with the button hook outstanding to the direction of annular recesses; Sealing-ring is positioned over annular recesses inside, is blocked among annular recesses by the button hook on annular recesses outer wall; All sides of upper cover are provided with a circle cover rim, when upper cover matches with base, in cover rim insertion annular recesses, and the bottom of cover rim and sealing-ring upper contact, sealing ring lower potion and annular recesses base and interior side contacts.
Further, the width of described sealing-ring is less than the width of annular recesses, and the width being greater than annular recesses subtracts the width that button hook projects to annular recesses.
Further, the outer wall of described cover rim is provided with groove, when upper cover matches with base, the button hook on base is in the groove of upper cover.
Advantageous Effects of the present utility model is:
1, sealing-ring is arranged in the base instead of in upper cover, sealing-ring difficult drop-off, and it is very big that upper cover thickness can do, and increases the intensity of upper cover;
2, sealing-ring is in free state, is not squeezed, and can not damage because of distortion; Sealing-ring can also be reduced to the extruding of box body, avoid box body deformability, be conducive to the raising of sealing property.
3, the device isolation of sealing-ring and box body inside is come by the inwall of annular recesses, it is possible to reduces being heated of sealing-ring, increases charged distance.

Fig. 1 is exploded view of the present utility model.
Fig. 2 is the structure iron of the utility model base.
Fig. 3 is the front sectional view after the utility model assembles.
Fig. 4 is the three-dimensional cutaway view after the utility model assembles.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, box body sealed structure of the present utility model mainly comprises base 1, upper cover 2 and sealing-ring 3.
As shown in Figure 2, the top of base 1 is provided with a ring annular groove 1-1, and the part of base 1 in the inside and outside both sides of annular recesses 1-1 be the inwall 1-2 of looping groove and the outer wall 1-3 of annular recesses respectively. The height of the inwall 1-2 of annular recesses is greater than the height of the outer wall 1-3 of annular recesses. Various devices in box body are installed in the region surrounded by the inwall 1-2 of annular recesses. The top of the outer wall 1-3 of annular recesses is provided with the many places button hook 1-4 outstanding to the direction of annular recesses 1-1. On the girth of outer wall 1-3 being distributed in annular recesses of each button hook 1-4 spacing such as almost. It is noted that diagram just better embodiment of the present utility model, in actual design, quantity and the distribution mode of button hook 1-4 can unrestricted choice.
As shown in Figure 3 and Figure 4, during installation, sealing-ring 3 is positioned in annular recesses 1-1, owing to the width of sealing-ring 3 is less than the width of annular recesses 1-1, and the width being greater than annular recesses 1-1 subtracts the width that button hook 1-4 projects to annular recesses 1-1, therefore sealing-ring 3 is blocked among annular recesses 1-1 by the hook 1-4 that buckles on annular recesses outer wall 1-3, and sealing-ring 3 drops down onto the bottom of annular recesses 1-1, can not drop out; When not installing upper cover 2, sealing-ring 3 itself can not be squeezed.
All sides of upper cover 2 are provided with a circle cover rim 2-1, and the width of cover rim 2-1 is less than the width of annular recesses 1-1, and the outer wall of cover rim 2-1 is provided with groove 2-2. During installation, cover rim 2-1 inserts in annular recesses 1-1, and the button hook 1-4 on base 1 falls into the groove 2-2 of upper cover 2, thus cover rim 2-1 is inserted smoothly and by the stop of button hook 1-4; After cover rim 2-1 is inserted into the end, its bottom and sealing-ring 3 upper contact, extruding sealing-ring 3 makes its underpart and annular recesses 1-1 base and interior side contacts, it is achieved seal. Make the inwall 1-2 of annular recesses forms independent space, structure relevant with sealing to sealing-ring 3 grade for the device wherein installed is isolated.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment. It can be appreciated that those skilled in the art are not departing under the prerequisite of basic design of the present utility model the oher improvements and changes directly deriving or associating, all should think and be included within protection domain of the present utility model.
