Abstract
The utility model is related to a kind of comprehensive shock resistance lens installation structures, including stack shell, light cup, U-shaped sealing ring and trim ring, light cup is positioned over inside stack shell, eyeglass is positioned on light cup, U-shaped sealing ring is threadedly coupled from lens edge, trim ring is wrapped circumferentially around with stack shell, and the end face of trim ring compresses U-shaped sealing ring, the circumferential direction of U-shaped sealing ring is in close contact with stack shell, and gap is respectively provided between the eyeglass and light cup and trim ring that are wrapped up by U-shaped sealing ring.The utility model wraps up eyeglass by using U-shaped sealed silicon cushion rubber, pass through the structure setting of trim ring, light cup and stack shell simultaneously, it is contacted directly so that eyeglass is avoided with other component, overcomes that prior art impact resistance is weaker, waterproof seal poor deficiency.
Description
Technical field
The utility model is related to lighting device technical field more particularly to a kind of mounting structures of eyeglass.
Background technology
The mounting structure of existing eyeglass is divided to two classes, and one kind is using O-shaped sealed silicon cushion rubber, and another kind is sealed using L-type
Silica gel ring.This two kinds are directly padded below eyeglass when installation, and the eyeglass is made to have the functions such as sealing waterproof buffering shock resistance.
Advantage is that simple in structure, cost is relatively low, and shortcoming is that the another side of eyeglass and other mechanisms contact directly, the impact resistance of eyeglass
Weaker, waterproof seal is poor.
The content of the invention
The purpose of the utility model is to overcome above-mentioned prior art impact resistance is weaker, waterproof seal is poor not
Foot, provides a kind of comprehensive shock resistance lens installation structure, and eyeglass is made to have stronger impact resistance, improves the anti-of eyeglass
Water sealing property.
Technical solution is used by the utility model：
Comprehensive shock resistance lens installation structure, including stack shell, light cup and trim ring, the light cup is positioned over inside stack shell,
The eyeglass is positioned on light cup, is characterized in that：
The mounting structure further includes U-shaped sealing ring, and the U-shaped sealing ring is from being wrapped circumferentially around lens edge, the trim ring
It is threadedly coupled with stack shell, the end face of trim ring compresses U-shaped sealing ring, and circumferential direction and the stack shell of U-shaped sealing ring are in close contact, by U-shaped close
Gap is respectively provided between the eyeglass of seal package and light cup and trim ring.
It is the basic structure of the utility model above, based on the basic structure, the utility model also makes following improvement：
Further, to promote water resistance, the lower sidewall setting of U-shaped sealing ring is tapered.
Further, to play the effect of the more pressing the more tight, stack shell at U-shaped sealing ring cooperation with being also equipped with and taper fit
Cone angle.
When further, to avoid trim ring with stack shell assembling, the rotation of trim ring causes to damage to U-shaped sealing ring, this practicality
New mounting structure further includes washer, and the washer is arranged between U-shaped sealing ring and trim ring.
Further, U-shaped sealing ring is sealed silicon cushion rubber.
The beneficial effects of the utility model are：
1st, the utility model wraps up eyeglass by using U-shaped sealed silicon cushion rubber, while passes through trim ring, light cup and cylinder
The structure setting of body so that eyeglass is avoided to be contacted directly with other component, and eyeglass is provided with comprehensive shock proof effect,
Sealing water resistance also has great promotion simultaneously.
2nd, the utility model is simple in structure, is skillfully constructed, and passes through the change of sealing ring form so that eyeglass has had both waterproof
With shock proof excellent performance, there is significant effect.
Description of the drawings
Fig. 1 is the explosive view of comprehensive shock resistance lens installation structure；
Fig. 2 is the structure diagram of comprehensive shock resistance lens installation structure.
In figure, 1. stack shells, 2. light cups, 3.U type sealing rings, 4. washers, 5. trim rings, 6. eyeglasses, 7- tapers, 8- cone angles.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Attached drawing 1 is referred to, which is a concrete application of the utility model on flashlight, in the present embodiment
In, the comprehensive shock resistance structure of eyeglass includes：Stack shell 1, the light cup 2 being positioned over inside stack shell 1 are positioned over above light cup 2
It eyeglass 6 and is coated on the U-shaped sealing ring 3 on 6 surface of eyeglass, the washer 4 being positioned over above U-shaped sealing ring 3 and passes through with stack shell 1
The trim ring 5 of threaded connection.
When flashlight assembles, by stack shell installation position vertically upward, after treating that internal component installs, by light cup 2
It is positioned on the commitment positions inside stack shell 1, then the eyeglass 6 for being coated with U-shaped sealing ring 3 is positioned on light cup 2, afterwards will
Washer 4 is positioned on U-shaped sealing ring 3, and the structure that trim ring 5 is connected through a screw thread finally is screwed into cylinder according to designed position
Body 1, the structure of formation is as shown in Figure 2.
In fig. 2, U-shaped sealed silicon cushion rubber wraps up eyeglass, and trim ring is threadedly coupled with stack shell, and the end face of trim ring compresses
U-shaped sealing ring, circumferential direction and the stack shell of U-shaped sealing ring are in close contact so that eyeglass has water-proof function.The side wall of U-shaped sealing ring
The taper 7 that lower part is set contributes to the sealing between U-shaped sealing ring and stack shell and light cup, and stack shell at U-shaped 3 cooperation of sealing ring with setting
The cone angle 8 coordinated with taper 7 is equipped with, to play the effect of the more pressing the more tight, promotes the water resistance of eyeglass.
Meanwhile the utility model passes through the structure setting of trim ring, light cup and stack shell so that eyeglass avoids and other component
Contact directly, be respectively provided with gap between eyeglass and light cup and trim ring, external impact will not directly act on eyeglass, eyeglass tool
There is comprehensive shock proof effect.
