Example Embodiment

[0033] in image 3 with Figure 4 In the illustrated embodiment of the sealing connection device of the present invention, by putting a plastic sleeve 8 on the rubber pad 5, the rubber pad 5 is reduced in contact with the outside and aging, and at the same time, the rubber pad 5 is structurally blocked and restricted. Forced expansion is applied to the periphery to maintain the positive pressure of the rubber pad 5 at the sealing surface of the sealed object (such as the through hole of the lamp body) in a constant state, so that the sealed object such as the lamp housing can achieve IP protection for a long time.

[0034] Combine image 3 with 4 , The lamp body 11 and the bracket 12 respectively have two prefabricated through holes at the corresponding positions, which are respectively used for the connection screw 2 (only one of which is indicated) to pass through. Among them, the lamp body 11 is an object that needs to be sealed after being connected to the bracket 12. From to...

Abstract

The invention provides a device for hermetically connecting objects. The device comprises a screw 2, a nut 7, a rubber mat 5 and a plastic sleeve gasket 8, wherein the screw 2 is provided with a cross recessed pan head; the nut 7 is engaged with the screw 2; the rubber mat 5 is arranged on the screw 2 and between the nut and a connected object; the plastic sleeve gasket 8 is sleeved on the rubber mat 5 and provided with an accommodation groove or hole 9 with a shape accordant with the rubber mat 5; and the depth of the accommodation groove or hole 9 is smaller than the thickness of the rubber mat 5. The device and a method for hermetically connecting objects provided by the invention are implemented and the plastic sleeve gasket is sleeved at the periphery of the rubber mat, so that the rubber mat can be protected and is prevented from aging and losing effectiveness by long-term exposure; moreover, the effective deformation of the rubber mat can be limited, a waterproof sealing surface is always in a tightly jointed protection state, long effectiveness of hermetic connection is ensured and the problem of poor sealing performance of a screw connecting piece in the prior art is better solved.

Description

technical field [0001] The present invention relates to mechanical connection technology, in particular to the sealing structure of threaded parts, more specifically, to a sealing connection device and method based on threaded connecting parts that can be used in lamps to improve their waterproof and dustproof performance in exposed use. Background technique [0002] Many products have very strict sealing requirements between the inside and the outside in consideration of factors such as safety, precision, and lifespan. Some of the sealing technologies in the prior art use colloid or such as welding. For example, on the basis of fastening by screws and nuts, the connection seam is welded to death by electric welding or sealant is applied to achieve sealing. This structurally fixed and sealed Although it has a certain degree of sealing, it cannot be repeated, and it is not suitable for many sealed connection occasions that need to be opened repeatedly; more sealing devices us...
