Detailed Description
The present utility model will be described in further detail with reference to specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be the communication between the two parts. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.
The first embodiment is as follows:
as shown in fig. 2, the utility model provides a linear speed sheath structure, which comprises a sheath body 1, a sealing ring 2 and a locking ring 6, wherein the sealing ring 2 can be sleeved on the sheath body 1, an external thread is arranged on the outer wall of the sheath body 1, an annular plane capable of supporting the sealing ring 2 is arranged on the sheath body 1, an internal thread is arranged in the locking ring 6, the locking ring 6 is in threaded connection with the sheath body 1, a heat insulation layer is attached on the annular plane capable of supporting the sealing ring 2 on the sheath body 1, the sheath body 1 can pass through a wire hole on a lamp housing 5, and the sealing ring 2 and the locking ring 6 are respectively positioned on the inner side and the outer side of the lamp housing 5.
The lamp housing 5 in the above structure drawing is a partially cut circular part, which is a part of the lamp housing, and when in use, the sealing ring 2 is sleeved on the sheath body 1, the sheath body 1 passes through a wire hole on the housing from one side of the lamp housing 5, the locking ring 6 is screwed with the sheath body 1 from the other side of the lamp housing 5, thereby completing the installation of the sheath structure, and as the part of the sheath body 1 contacted with the sealing ring 2 is provided with a heat insulation layer, the influence of the heat generated in the lamp housing on the sealing effect of the sealing ring 2 can be avoided to the greatest extent, meanwhile, the locking ring 6 is positioned outside the lamp housing and is in threaded connection with the sheath body 1, compared with the buckle connection in the prior art, the sealing connection can be ensured to the greatest extent.
The second embodiment is as follows:
as shown in fig. 3, in order to further reduce the influence of heat in the lamp housing on the sealing ring 2, a further optimization is performed based on the first embodiment, specifically: the lamp further comprises a ring body 5-1, the ring body 5-1 is positioned on the lamp shell 5, the outer side face of the sealing ring 2 is an annular slope face, the upper edge and the lower edge of the annular slope face are respectively positioned on the upper face and the lower face of the sealing ring 2, the ring body 5-1 is positioned on the face, in contact with the sealing ring 2, of the lamp shell 5, the ring body 5-1 is coaxial with the sealing ring 2, the surface of the ring body 5-1 is a smooth cambered surface, and the surface of the ring body 5-1 can be in contact with the annular slope face on the sealing ring 2.
