Abstract

The utility model relates to a flashlight, especially switch cap cover that rises of lamp pearl power supply by group battery. It has solved the technical problem that the switch easily falls out from the flashlight well, and its constitution is: the switch cap expansion sleeve which is arranged outside the flashlight barrel and is used for being sleeved with the lower end of the switch cap and is formed by plastic materials with good elasticity through injection molding is formed by connecting an upper rib position, a middle rib position and a lower rib position which are uniformly distributed on the circumference and are inverted and staggered with each other to form a circular fence-shaped framework.

Description

Switch cap riser

Technical field: The utility model relates to a flashlight that supplies power to lamp beads from a battery pack, especially a switch cap expansion sleeve.

Background technology: The common torch switch structure on the market is composed of a torch barrel, a switch assembly, and a switch cap. It is a structure in which the switch assembly is first fixed in the torch body, and then the switch cap is installed from the outside of the torch body. This structure has been widely used in flashlight products because the switch is fixed reliably and easy to assemble. In order to ensure the comfort when pressing the switch, the switch cap is generally made of rubber or silica gel with a Shore hardness below 75 degrees. , This will inevitably lead to the low strength of the commonly used switch cap, because the switch cap is loaded from the outside, it is easy to fall out of the flashlight barrel when pulled by an external force. The elasticity and strength of the top of the switch cap determine the feel when the switch is pressed, and the elasticity and strength of the periphery of the switch cap determine the reliability of the switch cap being fixed in the cylinder. Its disadvantages are: in one part of the same material, it is difficult to do this at a lower cost, so that the top of the switch cap has low strength and moderate elasticity, and it feels comfortable when pressed, and at the same time requires the switch cap The peripheral position of the switch cap has sufficient strength and elasticity to ensure that the switch cap has sufficient adhesion in the wall of the mounting hole of the flashlight barrel. Because the switch cap is packed from the outside, the seal between the switch cap and the flashlight barrel is not good.

Summary of the invention: the purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art and provide a method to enhance the strength and elasticity of the peripheral position of the switch cap and the sealing between the switch cap and the flashlight barrel, so as to ensure that the switch cap has a good pressing feel At the same time, it has good elasticity and sufficient adhesion, so that the switch cap does not fall out of the switch cap.

The purpose of this utility model can be achieved through the following measures: this kind of flashlight related to the power supply from the battery pack to the lamp bead, especially the switch cap expansion sleeve, includes the switch assembly fixed in the flashlight barrel and is installed from the outside of the flashlight barrel. The special feature of the switch cap is that the switch cap is inserted into the lower end of the switch cap and is made of plastic material with good elasticity by injection molding. The position, the middle rib position and the lower rib position are connected to form a circular fence-like structure.

Compared with the prior art, the utility model has the following advantages: reliable function, simple structure and convenient installation.

The description of the accompanying drawings is as follows:

Fig. 1 is a structural schematic diagram of the installation position of the switch cap expansion sleeve in the flashlight.

Fig. 2 is a perspective view of a switch cap.

Fig. 3 is a sectional view of the switch cap expansion sleeve.

Fig. 4 is the right side view of the switch cap expansion sleeve.

Fig. 5 is a left view of the switch cap expansion sleeve.

Fig. 6 is a perspective view of the expansion sleeve of the switch cap.

The specific embodiment: the utility model will be described in further detail below in conjunction with the accompanying drawings:

As shown in the figure, this kind of flashlight involving power supply from the battery pack to the lamp beads, especially the switch cap expansion sleeve 4, includes the switch assembly 2 fixed in the flashlight barrel 1 and the switch cap installed from the outside of the flashlight barrel 1 3. The switch cap expansion cover 4 is formed by injection molding of the plastic material with good elasticity, which is used for the peripheral position 8 of the switch cap. 7 lower ribs are connected to form a circular fence-like structure.

During use, the switch cap expansion sleeve 4 is loaded into the peripheral position 8 of the switch cap from the top 9 of the switch cap, and then the switch cap 3 is loaded into the barrel 1 of the flashlight.

Claims (1)

1. one kind relates to by the flashlight of battery pack to the power supply of lamp pearl, especially deflating cap ringfeder, comprise the switch module that is fixed in the flashlight shell and the deflating cap of packing into, it is characterized in that from the flashlight shell outside: for the deflating cap lower end be inserted in and by elasticity preferably the deflating cap ringfeder that is formed by injection molding of plastic material be inverted the staggered shrinkage pool that has each other by circumference uniform distribution and constitute and go up the paliform framework that muscle position, middle muscle position and following muscle position be linked to be a circle and form.
