Description

Technical Field

[0001] The utility model relates to a sliding interactive lock for a cover and a laser pointer including such a sliding interactive lock for a cover. Background Art

[0002] For most pen-shaped tools with protective covers, the cover body is mainly connected to the head end of the main body by means of threads. The cover body buckles the head end of the main body inside for protection. The cover body and the main body are detachably connected by a thread. This method is convenient for locking and disassembling. However, the cover body can also be easily unscrewed, and there may be a possibility of accidental opening and disassembly. For some special tools such as laser pointers, see Figure 6 , the cover body is installed at one end of the laser head to protect the laser head and can reduce the harm caused by the direct irradiation of the laser beam to the human eye. In order to facilitate the replacement and maintenance of the laser pointer, the cover body is usually designed to be detachable with a thread. This kind of laser pointer with a detachable pen cover looks like an ordinary writing tool and is easily misused by children or mistaken for a toy, increasing the risk of misuse. Especially when the pen cover of a high-power laser pointer is easily disassembled or accidentally disassembled during operation, the strong light beam emitted by the laser pointer will cause harm to the environment, eyes or other sensitive parts, resulting in a greater risk; and in the prior art, the detachable method of the pen cover does not protect vulnerable groups such as children and the elderly. Especially when the pen cover is not correctly locked, it is easy to cause accidental opening of the laser pointer. Summary of the Utility Model

A sliding switch 40 for controlling the power on and off is arranged on the main body 10. A sliding push button 50 is connected to the sliding knob 41 of the sliding switch 40. The sliding push button 50 slides along the axis direction of the main body 10 and its top end extends outside the main body 10. An insertion locking part 60 that can be axially inserted and matched is arranged between the sliding push button 50 and the cover body 20. When the sliding switch 40 is in the on state, the insertion locking part 60 is in the inserted state to circumferentially lock the main body 10 and the cover body 20. When the sliding switch 40 is in the off state, the insertion locking part 60 is in the unlocked state. When the sliding push button 50 slides to the end point in the direction away from the cover body 20, the sliding switch 40 is turned off and the insertion locking part 60 is unlocked. When the sliding push button 50 slides to the end point in the direction close to the cover body 20, the sliding switch 40 is turned on and the insertion locking part 60 is in the inserted and matched state.

[0024] In the prior art, the power on and off of the laser pointer is mainly achieved by pressing a button. However, in this application, the power on and off is achieved by the axial sliding of the sliding switch 40, and the power on and off can control the connection relationship between the main body 10 and the cover body 20. When the power is connected, there is not only a threaded connection relationship between the main body 10 and the cover body 20, but also an insertion and matching locking relationship. At this time, the main body 10 and the cover body 20 cannot be disassembled. When the power is turned off, only the threaded connection relationship remains between the main body 10 and the cover body 20. At this time, the cover body 20 can be disassembled from the main body 10 only by loosening the thread. This way of being able to disassemble the cover body 20 only when the laser pointer is in the off state improves the use safety while retaining the original detachable function.

[0025] The sliding switch 40 is arranged on the PCB board of the laser pointer to control the on and off of the laser pointer. Using the sliding switch 40 on the PCB board for power on and off control belongs to the prior art and will not be elaborated here.

[0026] See Figure 3 and Figure 4 , the threaded connection part 30 includes an external thread 31 arranged on the outer circumference of the main body 10 and an internal thread 32 arranged on the inner circumference of the cover body 20. The external thread 31 is threadedly connected with the internal thread 32. The external thread 31 is arranged on the main body 10 on the side close to the cover body 20 relative to the insertion locking part 60. The internal thread 32 is arranged on the cover body 20 on the side far from the main body 10 relative to the insertion locking part 60. The head end of the main body 10 can extend into the inside of the cover body 20 for threaded connection.

[0027] See Figure 3 andFigure 4 , the plug-in locking part 60 includes a plug-in slot 61 provided on the cover body 20. One end of the sliding push button 50 close to the cover body 20 is provided with a plug-in block 62 that is in plug-in fit with the plug-in slot 61. Both the plug-in slot 61 and the plug-in block 62 are arranged along the axial direction and their sizes are adapted. The plug-in slot 61 and the plug-in block 62 are rectangular slots or irregular polygonal slots.

[0028] See Figure 3 , a sliding opening 70 is provided on the main body 10 along the axial direction. The sliding push button 50 slides along the sliding opening 70, and the top end of the sliding push button 50 extends outside the sliding opening 70. In this embodiment, the sliding opening 70 can be an oval hole, and the sliding push button 50 has a cylindrical structure adapted to the oval hole. Of course, the sliding push button 50 can be rectangular, and the sliding opening 70 is a rectangular hole.

[0029] See Figure 3 , a connecting part 51 for connecting with the sliding button handle 41 of the sliding switch 40 is provided at the bottom end of the sliding push button 50. In this embodiment, a groove 42 is provided on the side surface of the sliding button handle 41. The connecting part 51 includes clamping arms 52 located on both sides of the sliding button handle 41. A convex block 53 is provided on the surface of the clamping arm 52 close to the sliding button handle 41. The convex block 53 is correspondingly clamped into the groove 42. The sliding push button 50 and the sliding button handle 41 are connected by the clamping of the convex block 53 and the groove 42.

[0030] The working principle of this embodiment is as follows:

[0031] When the cover body 20 is disassembled: First, push the sliding push button 50 to slide along the sliding opening 70 in a direction away from the cover body 20, driving the plug-in block 62 to disengage from the plug-in slot 61, and at the same time driving the sliding switch 40 to move from the open state to the closed state. When the sliding push button 50 slides to the end point, the plug-in block 62 is completely separated from the plug-in slot 61, that is, the plug-in locking part 60 is unlocked, and at the same time the sliding switch 40 is closed. At this time, rotate the cover body 20 so that the cover body 20 is unscrewed and disassembled from the main body 10. At this time, the power supply of the laser pointer after the cover body 20 is disassembled is disconnected. When it is necessary to turn on the laser pointer, push the sliding push button 50 in the reverse direction to drive the sliding switch 40 to turn on.

[0032] When the cover body 20 is installed: First, close the sliding switch 40 through the sliding push button 50, and then snap and tighten the cover body 20 to the head end of the main body 10.

[0033] By designing the sliding switch 40, when the laser pointer is turned on, the thread between the main body 10 and the cover 20 cannot rotate, achieving the function of non-detachability. Only when the laser pointer is in the off state can the cover 20 be detached, improving the safety while realizing the detachable function of the cover 20.
