Embodiment
Describe in detail with reference to the accompanying drawings according to box body sealing structure of the present utility model.
Referring to figs. 1 to Fig. 9, included according to box body sealing structure of the present utility model：Case lid 1, is provided with multiple first peaces
Fill hole 11；Casing 2, is assemblied in case lid 1；Sealing ring 3, is arranged between case lid 1 and casing 2；Multiple locating parts 4, are provided with logical
Hole 41；And multiple fasteners 5, the through hole 41 through corresponding locating part 4 is with lock sealing connection casing 2 and case lid 1.Its
In, each locating part 4 has：Insertion section 42, is inserted in corresponding first mounting hole 11；And stopper section 43, it is formed at insertion section
42 one end and backstop is in the top of case lid 1.
According in box body sealing structure of the present utility model, fastener 5 when lock sealing connects case lid 1 and casing 2,
The insertion section 42 of each locating part 4 is from the top crush seal circle 3 of sealing ring 3, and the length control sealing ring 3 based on insertion section 42
Decrement, good sealing effect.Because the backstop of stopper section 43 is in the top of case lid 1, so that locating part 4 was being mounted and dismounted
It is difficult to drop in journey.
According in box body sealing structure of the present utility model, reference picture 9, the shape of insertion section 42 can be it is cylindric, only
The shape of stopper 43 is also cylindric, and now, the external diameter of stopper section 43 is more than the external diameter of insertion section 42.Here, due to stopper section
43 are in the tops of case lid 1, and the shape of stopper section 43 is not limited only to cylindric, can also be square or other shapes, and insertion section
42 shape is limited by the first mounting hole 11.
According in box body sealing structure of the present utility model, reference picture 8, casing 2 is provided with multiple second mounting holes 21,
Sealing ring 3 is provided with multiple 3rd mounting holes 31.Case lid 1 has eaves portion 12, and each insertion of first mounting hole 11 is arranged at eaves portion 12,
Casing 2 has eaves portion 22, and each insertion of second mounting hole 21 is arranged at eaves portion 22.The setting of eaves portion 12 and eaves portion 22 be for the ease of
The assembling of case lid 1 and casing 2.
According in box body sealing structure of the present utility model, referring to figs. 1 to Fig. 8, box body sealing structure may also include：Pressure
Bar 6, positioned at the top of the eaves portion 12 of case lid 1 and is provided with multiple 4th mounting holes 61.Each locating part 4 during lock sealing
Insertion section 42 inserted via the 4th mounting hole 61 in corresponding first mounting hole 11 and the backstop of stopper section 43 of each locating part 4 exists
The top of press strip 6.Now, each fastener 5 directly extrudes the stopper section 43 of corresponding locating part 4, and stopper section 43 is between press strip 6
Extruding case lid 1 is connect, so as to avoid case lid 1 because of the risk that local stress is excessive and damages, the life-span of case lid 1 is extended.
According in box body sealing structure of the present utility model, reference picture 4 to Fig. 7, the length of the insertion section 42 of each locating part 4
Degree more than the eaves portion 12 of thickness and the case lid 1 of press strip 6 thickness sum, and the thickness less than press strip 6, the thickness of eaves portion 12 and
The thickness sum of sealing ring 3, and diameter of the diameter equal to the 4th mounting hole 61 of the first mounting hole 11.
With further reference to Fig. 4 and Fig. 5, the diameter of the 3rd mounting hole 31 is equal to the diameter of the second mounting hole 21, and less than the
The diameter of one mounting hole 11.During lock sealing, the insertion section 42 of each locating part 4 is directly squeezed in the presence of fastener 5
Pressure seal ring 3, and (now the decrement of sealing ring 3 is equal to the decrement of the control sealing ring 3 of the length scale based on insertion section 42
The length of each insertion section 42 subtracts the thickness sum of the thickness of press strip 6 and the eaves portion 12 of case lid 1).
With further reference to Fig. 6 and Fig. 7, the diameter of the 3rd mounting hole 31 is equal to the diameter of the first mounting hole 11, and more than the
The diameter of two mounting holes 21.During lock sealing, the insertion section 42 of locating part 4 via sealing ring 3 the 3rd mounting hole 31,
Slowly moved down in the presence of fastener 5 up to directly being contacted with casing 2, so that the lock sealing of case lid 1 and casing 2 is completed,
And (now the decrement of sealing ring 3 is equal to press strip 6 to the decrement of the length scale control sealing ring 3 based on each insertion section 42
The thickness sum of thickness, the thickness of eaves portion 12 and sealing ring 3 subtracts the length of each insertion section 42).
When box body sealing structure is not provided with press strip 6, the length of the insertion section 42 of each locating part 4 is more than the eaves of case lid 1
The thickness in portion 12, and the thickness sum of the thickness and sealing ring 3 less than eaves portion 12.Wherein, the diameter of the 3rd mounting hole 31 is equal to
The diameter of second mounting hole 21, and less than the first mounting hole 11 diameter (now the decrement of sealing ring 3 be equal to each insertion section 42
Length subtract case lid 1 eaves portion 12 thickness)；Or the 3rd mounting hole 31 diameter be equal to the first mounting hole 11 diameter,
And more than the second mounting hole 21 diameter (now the decrement of sealing ring 3 be equal to thickness and the sealing ring 3 of eaves portion 12 thickness it
With the length for subtracting each insertion section 42).
Here remark additionally, the decrement of sealing ring 3 needs suitable control, if decrement is too small, sealing effectiveness
Difference, if decrement is too big, is easily caused seal failure.Therefore, in actual production, the decrement based on sealing ring 3 is reasonable
The length of insertion section 42 of locating part 4 is adjusted to reach better seal effect.
According in box body sealing structure of the present utility model, each locating part 4 can be T-shaped axle sleeve, and fastener 5 can be spiral shell
Bolt.Case lid 1 can be made up of metal material, can be also made up of nonmetallic materials.Casing 2 can be made up of metal material, also can be by non-
Metal material is made.Here, nonmetallic materials can be composite or plastics.
