Abstract
The utility model discloses an improved flashlight which comprises a casing, a switch arranged on the outer surface of the casing and a circuit board, a light-emitting diode (LED) lamp and a power supply which are arranged in the casing. The casing is of a hollow column structure, the circuit board and the power supply are respectively arranged in the casing, the LED lamp is installed on the circuit board, the light-emitting face of the LED lamp faces the front end of the casing, a lamp shade is arranged at the front end of the casing, a light-reflection bowl is arranged in the lamp shade, the light-emitting face of the LED lamp is embedded in the light-reflection bowl, a back cover is arranged at the back end of the casing, and the power supply, the switch and the LED lamp are sequentially and electrically connected. The casing is a plastic casing formed in injection molding mode. The improved flashlight is good in sealing performance due to the fact that the casing is the plastic casing formed in injection molding mode and is of an integral structure, is good in waterproof performance, cannot be cracked if falling on the ground, and prolongs service life. Simultaneously, the casing is the plastic casing, so that the flashlight has the advantages of being low in production cost, light in weight and convenient to carry.
Description
Technical field
The utility model relates to lighting apparatus, particularly a kind of flashlight.
Background technology
The advantages such as flashlight is prevailing a kind of in the lighting apparatus, and it has practical, good illumination effect, energy-conserving and environment-protective, be easy to carry, it is widely used in people's life, such as night trip illumination, long camping trip illumination etc.But traditional flashlight, its housing generally adopt aluminium alloy to make, and have a production cost high, and Heavy Weight is not easy to carry, the defective of complex manufacturing; In order to solve this defective, the housing that adopts plastics to make has appearred in the market, but this housing is formed by two halves shell make-up, the two halves shell breakage of easily splitting after falling on the ground, service life is short, and whole sealing is relatively poor, causes the water resistance of flashlight very not good.
The utility model content
It is better that the purpose of this utility model provides a kind of water resistance, and fall on the ground that back casing can not split, the modified flashlight of long service life.
The technical solution of the utility model is such: a kind of modified flashlight, comprise housing, be located at the switch of housing outer surface, and be located at circuit board in the housing, LED lamp and power supply, this housing is the opening-like hollow columnar structures in two ends, this circuit board and power supply are located at respectively in the housing, this LED lamp is installed on the circuit board, and the light-emitting area of this LED lamp is towards the front end of housing, the front end of this housing is provided with lampshade, is provided with reflector in this lampshade, and the light-emitting area of LED lamp is embedded in this reflector, the rear end of this housing is provided with the bonnet of this housing rear end port of sealing, this power supply, switch and LED lamp are electrically connected successively; Above-mentioned housing is integrated the plastic casing of injection mo(u)lding.
The outer surface of above-mentioned housing is concaved with some the strip grooves that arrange along the length direction of above-mentioned housing, and each above-mentioned strip groove is along the setting spaced apart of the circumferencial direction of above-mentioned housing.
The lateral wall of above-mentioned bonnet is provided with external screw thread.
The front end lateral wall of above-mentioned housing is provided with external screw thread.
After adopting technique scheme, a kind of modified flashlight of the present utility model is because housing is integrated the plastic casing of injection mo(u)lding, be that housing is overall structure, good airproof performance makes the water resistance of flashlight splendid, and can not split shape after falling on the ground, prolong the service life of flashlight; Simultaneously, housing is plastic casing, has a production cost low, lightweight, portable advantage; Because the outer surface of housing is concaved with some the strip grooves that arrange along the length direction of housing, and each strip groove is along the setting spaced apart of the circumferencial direction of housing, like this, arranging on the one hand of each strip groove can be saved the material of making housing, further reduce production costs, also can play decoration function to housing on the other hand; Because the lateral wall of bonnet is provided with external screw thread, the user is difficult for skidding when the dismounting bonnet so again.
Description of drawings
Fig. 1 is stereogram of the present utility model.
Among the figure:
Housing 1 strip groove 11
The specific embodiment
A kind of modified flashlight of the present utility model, as shown in Figure 1, comprise housing 1, be located at the switch (not shown in FIG.) of housing 1 outer surface, and be located at circuit board (not shown in FIG.) in the housing 1, LED lamp (not shown in FIG.) and power supply (not shown in FIG.), this housing 1 is the opening-like hollow columnar structures in two ends, this circuit board and power supply are located at respectively in the housing 1, this LED lamp is installed on the circuit board, and the light-emitting area of this LED lamp is towards the front end of housing 1, the front end of this housing 1 is provided with lampshade 2, be provided with reflector (not shown in FIG.) in this lampshade 2, and the light-emitting area of LED lamp is embedded in this reflector, and the rear end of this housing 1 is provided with the bonnet 3 of this housing 1 rear end port of sealing, this power supply, switch and LED lamp are electrically connected successively.The structure of beginning of the present utility model, circuit board, LED lamp, power supply and reflector is identical with structure and the installation site of beginning, circuit board, LED lamp, power supply and the reflector of existing flashlight with the installation site, and the applicant is not repeated at this.
Improvements of the present utility model are: housing 1 is integrated the plastic casing of injection mo(u)lding, the outer surface of this housing 1 is concaved with some the strip grooves 11 that arrange along the length direction of housing 1, and each strip groove 11 is along the setting spaced apart of the circumferencial direction of housing 1, the front end lateral wall of this housing 1 is provided with external screw thread 12, is equipped with external screw thread 31 on the lateral wall of this bonnet 3.
A kind of modified flashlight of the present utility model, because housing 1 is integrated the plastic casing of injection mo(u)lding, namely housing 1 is overall structure, good airproof performance, make the water resistance of flashlight splendid, and can not split shape after falling on the ground, prolonged the service life of flashlight; Simultaneously, housing 1 is plastic casing, has a production cost low, lightweight, portable advantage; Because the outer surface of housing 1 is concaved with some the strip grooves 11 that arrange along the length direction of housing 1, and each strip groove 11 is along the setting spaced apart of the circumferencial direction of housing, like this, arranging on the one hand of each strip groove 11 can be saved the material of making housing, further reduce production costs, also can play decoration function to housing on the other hand; Because be equipped with external screw thread 12,31 on the front end lateral wall of housing 1 and the lateral wall of bonnet 3, this external screw thread 12,31 plays skidproof effect, the user is difficult for skidding when dismounting lampshade 2 and bonnet 3 like this.
