Description

Technical Field

[0001] This utility model relates to a tactical lighting device for firearms. Background Technology

[0002] To facilitate target search and provide illumination, tactical lights need to be mounted on firearms. Existing tactical lights typically use button batteries as a power source. These batteries have small capacity and short operating time, and as disposable power sources, they easily cause environmental pollution. Furthermore, the switch for tactical lights is usually located on the left or right side of the light. Pressing the switch can easily cause the firearm to be pushed sideways, resulting in the light's illumination and aiming direction deviating from the target, thus affecting shooting accuracy. Utility Model Content

[0003] To achieve the above objectives, this utility model proposes a tactical light for firearms, the tactical light comprising: The base includes a battery cavity and a lamp head located at the front end of the battery cavity. The battery cavity is composed of a bottom plate and a front upright plate and a rear upright plate located on the bottom plate. A light source is installed inside the lamp head. The base is fixed to the bottom of the base and includes a mounting part that can be mounted on the gun rail; A battery module, which is detachably installed in the battery cavity, is composed of a rechargeable battery; The circuit board, mounted and fixed on the base, is used to connect and control the battery module and the light source, and has a power connection part installed on it.

[0004] The battery module in this application is constructed using a rechargeable battery, preferably a lithium-ion battery from the prior art, to improve battery utilization and reduce environmental pollution. Because the battery module is detachable, it can be easily replaced for alternating charging, ensuring the continued use of the tactical lighting equipment.

[0005] Furthermore, to ensure a stable connection between the battery module and the power connection, the power connection is equipped with a pair of elastically retractable contact posts, which are electrically connected to corresponding contact points on the battery module. The elasticity of the contact posts ensures a stable electrical connection between the battery module and the power connection, and also prevents poor contact caused by wear.

[0006] Furthermore, the power connection portion is equipped with a pair of lower adsorption components for adsorption and positioning. These lower adsorption components are located on both sides of the contact post, and an upper adsorption component is located on the underside of the battery module. The upper and lower adsorption components are positioned opposite each other and can magnetically adsorb each other. One of the upper and lower adsorption components is a magnet, and the other is made of a magnet or a magnetic material. This magnetic material refers to a material that can be attracted by a magnet; specifically, the magnetic material can be iron, steel, or nickel-cobalt alloys, etc. This design allows for a magnetic connection between the battery module and the circuit board, facilitating the removal or installation of the battery module from the base.

[0007] Furthermore, in order to facilitate the connection of the power connector to the battery module, a through-hole-shaped magnetic cavity is provided on the base plate, and the power connector is housed in the magnetic cavity.

[0008] Furthermore, the front upright plate extends rearward toward the battery cavity to form an extension portion, and an elastic retaining member is provided on each side of the extension portion. Two lugs are provided on the front surface of the battery module along the vertical direction of the two side edges. The extension portion is placed between the two lugs. A retaining rib is provided on the inner side of each lug, and the retaining rib is held on the lower side of the elastic retaining member.

[0009] Specifically, the elastic retaining member has an outwardly protruding, elastically deformable curved portion, one end of which is detachably mounted on the extension, and the other end is formed as a free end.

[0010] This design not only allows for quick replacement of the battery module, but also ensures that the battery module remains stably within the battery cavity.

[0011] Furthermore, in order to enable the battery module to be quickly positioned on the tactical light, a positioning hole is provided on the rear surface of the battery module, and an elastic positioning bead that can be elastically pressed into the positioning hole is provided on the side of the rear upright plate facing the battery cavity.

[0012] Furthermore, to maintain the stability of the battery module on the tactical light, a limiting block is provided on the side of the rear panel facing the battery cavity, and a limiting groove is provided on the rear surface of the battery module. The limiting groove is limited on the limiting block, and a positioning hole is provided on the inner wall surface of the limiting groove.

[0013] Furthermore, a power switch is installed on the side of the rear panel away from the battery compartment. This power switch is a push-button switch, which includes a switch base. The switch base includes a base plate and two hinge ears disposed on the left and right sides of the base plate. The base plate is hinged to the rear panel via the hinge ears. Two buttons are provided on the side of the base plate away from the rear panel, spaced apart in the left-right direction. In this application, the power switch is located on the rear side of the base, that is, directly behind the tactical light. Since the pressing direction of the button is the same as the length direction of the firearm, pressing the power switch will not cause the aiming direction of the firearm to deviate. In the prior art, the power switch button is generally located on the left or right side of the tactical light. When the switch is pressed, it is easy to cause lateral push to the firearm, causing the illumination direction and aiming direction of the tactical light to deviate from the target. This design successfully overcomes this problem. In addition, this application provides two buttons in the left-right direction, allowing the user to choose one to press according to their habits, or to choose to press both buttons according to the specific situation.

[0014] Furthermore, to facilitate the reset of the power switch, the power switch also includes a reset spring and a button spring. The reset spring is located between the base plate and the rear plate, with at least one end of the reset spring fixed to the rear plate or the base plate. The button spring is fixedly mounted on the rear plate and electrically connected to the circuit board. A pressing head for pressing the button spring is mounted on the base plate. The reset spring enables the base plate to automatically reset after being pressed. Attached Figure Description
