Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, in a first embodiment of the waterproof gland for lenses according to the present utility model, the gland 10 includes a circular sleeve 11, an annular boss 12 fixed on a first end of an inner sidewall of the sleeve 11 near a first end surface of the sleeve 11 and extending toward an inner center of the sleeve 11, an annular step 13 fixed on a periphery of an outer side surface of the annular boss 12, and an annular ramp 14 fixed between the annular step 13 and the first end surface of the sleeve 11, wherein a width of the annular boss 12 is larger than a width of the annular step 13.

It will be appreciated that the width of the annular boss 12 is greater than the width of the annular step 13, i.e. the diameter of the inner bore of the annular boss 12 is less than the diameter of the inner bore of the annular step 13. When the waterproof glass cover sheet 15 is installed, the waterproof glass cover sheet 15 is installed in the annular step 13 and abuts against the protruding portion of the annular boss 12.

In this embodiment, the pressing cover 10 further includes a waterproof glass cover sheet 15, the thickness of the waterproof glass cover sheet 15 is equal to the height of the annular step 13, and the diameter of the inner hole of the annular boss 12 is smaller than the diameter of the waterproof glass cover sheet 15.

When the waterproof gland 10 for the lens is assembled, the sleeve 11 is fixed on the lens, at the moment, the inner side surface of the annular boss 12 abuts against the lens, then the waterproof glass cover plate 15 is installed in the annular step 13, the waterproof glass cover plate 15 abuts against the protruding part of the annular boss 12, finally the annular sealing rubber ring 18 is formed by gluing the periphery of the waterproof glass cover plate 15 and the annular inclined table 14 in a full circumference mode, and gaps between the waterproof glass cover plate 15 and the annular step 13 and gaps between the waterproof glass cover plate and the annular inclined table 14 are sealed, so that sealing waterproof performance is formed. In this application, through setting up the adhesiveness that annular sloping platform 14 can increase sealant 18, play better sealed effect, the sealed equipment of camera lens of being convenient for simultaneously reduces the production, the equipment degree of difficulty of gland 10 and camera lens.

Specifically, the bottom end of the annular step 13 is fixedly connected with the top surface of the annular boss 12, and the top end of the annular step 13 is fixedly connected with the bottom end of the annular inclined table 14.

To facilitate connection of the gland 10 to the lens body, the inner side wall of the sleeve 11 is provided with internal threads 16.

Further, in order to achieve a better sealing effect, the second end face of the sleeve 11 is provided with an annular groove 17 recessed into the sleeve 11.

The annular groove 17 is internally provided with a sealing gasket, and when the gland 10 is connected with the lens body, the sealing gasket can be arranged in the annular groove 17 in a gasket mode, and the sealing gasket seals a gap between the gland 10 and the lens body to form a sealing connection effect.

As shown in FIG. 1, the annular ramp 14 is inclined at an angle α of 30 α.ltoreq.α.ltoreq.60. Preferably, the angle of inclination of the annular ramp 14 is 45 °.

In addition, in the present utility model, unless explicitly specified and limited otherwise, the terms "connected," "stacked," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
