Abstract

The utility model discloses a simple flashlight which comprises a hollow columnar outer shell, a power source is arranged in the outer shell, a bulb is arranged at the front end of the outer shell, a sealing cover is arranged at the rear end of the outer shell, the sealing cover is movably connected with the outer shell, the bulb is connected with two wires, one wire is connected to the power source, and the end portion of the other wire is mounted on the sealing cover. A wire connected to the power source is mounted at a position, close to the sealing cover, of the outer shell, when the sealing cover is rotated, the wire on the sealing cover is in contact with the wire on the outer shell, and then a circuit formed by the power source, the three wires and the bulb is connected. A metal spring piece is arranged on the sealing cover, the end portion of the wire on the sealing cover is connected to the metal spring piece, a groove is formed in the outer shell, the end portion of the wire on the outer shell is arranged in the groove, and when the sealing cover is rotated, the metal spring piece is placed in the groove, and then the metal spring piece is in contact with the wire in the groove. The flashlight is simple in structure, can be manufactured by a user himself, can be made from various waste materials, and is low in cost and friendly to environment.

Description

Simple flashlight
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of homemade Simple flashlight.
Background technology
In daily life, often can use flashlight, flashlight is generally to control by switch, and switch can be arranged on each position of flashlight, is advisable with handled easily.But general flashlight is for battery, and the size of bulb etc. has fixing requirement, can not arbitrarily regulate.But can be by oneself making the flashlight of oneself liking by hand.
The utility model content
The purpose of this utility model is to provide a kind of Simple flashlight, and this flashlight structure is simple, can oneself make, and can utilize various waste and scraps, low cost and environmental protection.
The technical solution adopted in the utility model is as follows: a kind of Simple flashlight, the shell that comprises hollow columnar, power supply is set in shell, the shell front end is provided with bulb, the rear end arranges capping, wherein capping and shell are flexibly connected, bulb connects two wires, wherein one is connected on power supply, the end of another root is arranged in capping, connects the position that a wire is arranged on close capping on shell on power supply, when capping is rotated, contact with wire on shell in capping, the circuit that this moment, power supply, three wires and bulb formed is connected.
In technique scheme, be provided with metallic spring in described capping, wire termination in capping is connected on metallic spring, be provided with groove on shell, wire termination on shell is arranged in groove, when capping was rotated, metallic spring was placed in groove, and the interior wire of this moment metallic spring and groove contacts.
In technique scheme, the connecting portion with capping on described shell is provided with bulge-structure, is provided with baffle structure in capping, and when the capping rotation, when baffle structure was blocked by bulge-structure, the wire in capping this moment contacted with the wire on shell.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
This flashlight structure is simple, can oneself make, and can utilize various waste and scraps, low cost and environmental protection.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the another kind of structural representation of the utility model;
Fig. 3 is the another kind of structural representation of the utility model;
Reference numeral in figure: the 1st, shell 2 is that power supply 3 is bulbs
The 4th, capping 5 is that metallic spring 6 is grooves
The 7th, bulge-structure 8 is baffle structure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model is by forming circuit with power supply, bulb and 3 wires, the position that utilizes capping to be connected with shell makes contact and disconnection between wire, when capping is rotated, can be with two wire contacts, also can rotate two wires are staggered, thus the break-make of control circuit, and then make bulb bright or do not work.In order better to control contact and the disconnection of two wires, as shown in Figure 2, groove can be set on shell, a spring leaf is set in capping, spring leaf generally is made with metal material, when the capping rotation made metallic spring be placed in groove, circuit communication continued rotation, when spring leaf screws out in the groove, circuit disconnects, and arranging of sheet metal and groove can remind the end user to be rotated in place, convenient operation.Further improve, as shown in Figure 3, can when two structure contacts, automatically stop by in capping He on shell, catch and bulge-structure being set respectively, prompting is rotated in place, and this moment, two wires just contacted, circuit communication.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
