Description

portable flashlight

Technical field:

The utility model relates to the technical field of daily necessities, in particular to a flashlight with small and exquisite appearance, strong light collecting performance and easy to carry.

technical background:

As we all know, there are many kinds of household portable lighting tools, such as long cylindrical flashlights powered by batteries, portable flashlights using sulfuric acid solution as electrolytes, and miniature flashlights, etc., which are suitable for different occasions according to their power and battery energy. Among them, the miniature flashlight is small in shape and easy to carry. It is not only practical, but also highly decorative, so it is very popular among fans. However, most of the existing miniature flashlights are elongated or rectangular, and generally adopt 5# batteries or 7# batteries as the power supply, and the light emitted by the bulbs is weak, so its practicability is very limited, and their volume is still relatively large , It is not suitable to be carried as easily as hanging a key.

Technical content:

The purpose of the utility model is to provide a flashlight with small and exquisite appearance, strong light collecting performance and easy to carry.

The utility model is realized through the following technical scheme: the shell is formed by connecting the upper shell and the lower shell through bolts; the control key of the switch passes through the through hole of the upper shell and is exposed outside, and the bump at the upper end is supported on the cylinder of the lower shell , the bump at the lower end interferes between the two positioning bosses of the upper shell; the bulb is fixedly connected between the semicircular hole at the end of the upper shell and the semicircular hole at the end of the lower shell, and its positive terminal is set on the lower shell In the groove of the shell, the negative terminal is clamped in the groove of the switch; the lower shell is also provided with a bump for fixing the zinc sheet battery.

Due to the use of zinc sheet batteries as the power source, the volume of the utility model can be greatly reduced, so that the utility model is smaller and lighter than similar miniature flashlights, and is more suitable for carrying; Smooth and smooth, its decoration and appreciation are stronger than ordinary miniature flashlights. Strong, the light emitted by the bulb is bright, so the practicability of the utility model is enhanced; and the cost of the utility model is significantly reduced with the reduction in volume and material consumption.

See Fig. 1, 2, 3, 4, the utility model comprises shell 1, switch 2 and bulb 3, and shell 1 is formed by connecting upper shell 11 and lower shell 12 by bolts, and a certain position in the middle of upper shell 11 is provided with two A bump 115, two bumps 126 are provided at the middle position of the lower casing 12, and one end of the upper casing 11 is provided with a through hole 112, and the corresponding position of the lower casing 12 is provided with a through hole 122; the control key 21 of the switch 2 Through the through hole 111 of the upper shell 11 and exposed outside, the protrusion 24 at the upper end is supported on the cylinder 121 on the lower shell 12, and the protrusion 25 at the lower end interferes between the two positioning bosses 114 of the upper shell 11; the light bulb 3 is a light-emitting diode, the positive terminal 31 of which is set in the groove 120 of the lower casing 12, and the negative terminal 32 is clamped in the groove 22 of the switch 2; the lower casing 12 is also provided with a bump 124 for fixing the zinc sheet battery , 125.

See Figures 5 and 6, the lower shell 12 is provided with bumps 124, 125, 126 and cylinder 121, and is provided with a semicircular hole 123 and a through hole 122; at the same time, several bosses 127 are provided on the lower shell 12, and A through hole 128 is provided on the boss 127 , and a semicircular hole 129 with a larger diameter is provided at the inner end of the semicircular hole 123 . See Figures 7, 8 and 9, the upper housing 11 is provided with a positioning boss 114 and a projection 115, and is provided with through holes 111, 112 and a semicircular hole 113; at the same time, a corresponding boss 127 is provided with a boss 116 , and a threaded hole 117 is opened corresponding to the through hole 128 on the boss 127 , and a semicircular hole 118 is opened corresponding to the semicircular hole 129 of the lower shell 12 . See Figures 10 and 11, the switch 2 is provided with a control key 21, a bump 24, a bump 25 and two semicircular bumps 23, and is provided with a groove 22, and the control key 21 passes through the through hole of the upper shell 11 111 is exposed outside for manual control, the bump 24 on the upper end of the switch 2 is supported on the cylinder 121 on the lower casing 12, and the bump 25 on the lower end is in contact between the two positioning bosses 114 of the upper casing 11, during the movement of the switch 2 Among them, the semicircular protrusion 23 is in contact with the upper shell 11, which can reduce the contact area between the switch 2 and the upper shell 11, thereby reducing its frictional resistance. Zinc flake batteries are arranged on the protrusions 125 of the lower case 12 , and are axially fixed by two protrusions 115 in the middle of the upper case 11 , and radially fixed by the protrusions 124 , 126 on the lower case 12 . Fig. 12 is a three-dimensional structure diagram of the bulb 3, the large end of the bulb 3 is clamped in the cavity formed by the semicircular holes 118, 129, so that the bulb 3 is fixed between the semicircular holes 123 and 113, and its positive electrode The terminal 31 is set in the groove 120 of the lower housing 12 , the negative terminal 32 is clamped in the groove 22 of the switch 2 , and the column 121 is clamped between the above two terminals to prevent the bulb 3 from rotating. See Fig. 5, 7, upper shell 11 and lower shell 12 pass through threaded hole 117 and through hole 128 to form fixed connection by screw, can match key chain ring in the through hole 112 and 122, so that the utility model is carried.

When using the utility model, push the control key 21 of the switch 2, the projection 24 is supported on the cylinder 121 and slides along its end surface, and the inner slope of the groove 22 presses the end of the negative pole terminal 32 of the bulb 3 to the zinc sheet The negative pole of battery, because the positive pole of zinc flake battery has been connected with the positive pole terminal 31 of bulb 3, when negative pole terminal 32 was connected with the negative pole of zinc flake battery, bulb 3 will shine; Then the groove 22 of the switch 2 returns to the original position, and the negative pole terminal 32 breaks away from the contact with the negative pole of the zinc sheet battery, and the bulb 4 stops emitting light at this moment. In a word, adopting the zinc sheet battery can greatly reduce the volume of the utility model, thereby making the utility model smaller and lighter than similar miniature flashlights, so the cost of the utility model is significantly reduced, and it is also more portable; 1 is a curved shape, smooth and smooth, and its decorative and ornamental properties are stronger than ordinary miniature flashlights. It looks elegant and is suitable for hanging on a key chain like a key; The light performance is strong, thereby improving the practicability of the utility model.
