Description

Technical Field

[0001] The utility model relates to the technical field of flashlights, in particular to a flashlight that can be quickly assembled and disassembled. Background Art

[0002] The connection between the lamp cap assembly and the lamp tube assembly of the flashlight in the prior art is generally a threaded connection. The disadvantage of this connection method is that it is inconvenient to assemble and disassemble, and the lamp cap assembly needs to be rotated continuously to separate the lamp cap assembly from the lamp tube assembly. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a flashlight that can be quickly assembled and disassembled.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions.

[0005] A flashlight that can be quickly assembled and disassembled includes a lamp holder assembly and a lamp tube assembly. A spring pin that can be electrically connected to the lamp holder assembly is provided inside the lamp tube assembly. A conductive member that can be pressed into contact with the spring pin to achieve electrical connection is provided inside the lamp holder assembly. A U-shaped clip is provided inside the side of the lamp tube assembly connected to the lamp holder assembly. An annular groove that can be engaged with the U-shaped clip is provided on the side wall of the lamp holder assembly. A pressing member is provided on the lamp tube assembly for propping open the opening of the U-shaped clip to disengage the annular groove.

[0006] As a further improvement of the present invention, the opening of the U-shaped clip is provided with a first inclined surface, and the pressing piece is provided with a second inclined surface adapted to the first inclined surface so as to open the opening of the U-shaped clip when the pressing piece is pressed downward.

[0007] As a further improvement of the present invention, a mounting bar capable of being embedded into the interior of the lamp tube assembly is provided at the bottom of the U-shaped clip.

[0008] As a further improvement of the present invention, a third inclined surface is provided on the side of the U-shaped clip close to the lamp head assembly, and a fourth inclined surface is provided on the lamp head assembly, which is adapted to the third inclined surface and is used to open the opening of the U-shaped clip when the lamp head assembly is pressed down so that the U-shaped clip can slide into the annular groove.

[0009] Beneficial effects of the utility model

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] The U-shaped clip is then snapped into place in the annular groove to achieve mechanical structural connection and fixation, the conductive member is connected to the spring pin to achieve electrical communication, and the spring pin is in a compressed elastic force storage state, and the flashlight is installed. When the lamp holder assembly needs to be replaced or disassembled, the pressing member is pressed down to open the U-shaped clip opening, and the U-shaped clip and the annular groove are disengaged. The elastic force of the spring pin ejects the lamp holder assembly, thereby achieving disassembly of the lamp holder assembly and the lamp tube assembly, and the installation and disassembly speed is fast.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6 A flashlight that can be quickly assembled and disassembled includes a lamp holder assembly 1 and a lamp tube assembly 2. The lamp tube assembly 2 is provided with a spring pin 21 that can be electrically connected to the lamp holder assembly 1. The lamp holder assembly 1 is provided with a conductive member 11 that can be pressed into contact with the spring pin 21 to achieve electrical connection. A U-shaped clamp 22 is provided inside the side of the lamp tube assembly 2 connected to the lamp holder assembly 1. The side wall of the lamp holder assembly 1 is provided with an annular groove 12 that can be engaged with the U-shaped clamp 22. A pressing member 3 is provided on the lamp tube assembly 2 for propping open the opening of the U-shaped clamp 22 to disengage the annular groove 12.

[0020] The working principle of the present invention is as follows: the lamp holder assembly 1 is pressed into the lamp tube assembly 2, at which time the U-shaped clip 22 is clipped into the annular groove 12 to achieve mechanical structural connection and fixation, the conductive member 11 is connected to the spring pin 21 to achieve electrical communication, at which time the spring pin 21 is in a compressed elastic force storage state, and the flashlight is installed; when it is necessary to replace and disassemble the lamp holder assembly 1, the pressing member 3 is pressed down to open the opening of the U-shaped clip 22, at which time the U-shaped clip 22 is disengaged from the annular groove 12, and the elastic force of the spring pin 21 pops out the lamp holder assembly 1, thereby realizing the disassembly of the lamp holder assembly 1 and the lamp tube assembly 2, and the installation and disassembly speed is fast.
