Embodiment 1
[0029] The method includes the following steps:
[0030] Step 1. Select Mg-Zn-Ca-Sm-Be alloy as the substrate, polish the surface with 600, 800, 1000 and 1200# sandpaper in turn, and then use acetone and alcohol to ultrasonically clean it for 15 minutes;
[0031] Step 2, with NaAlO 2 :2g / L,NaOH:3g / L,nano-Al 2 o 3 :lg / L and sodium dodecylbenzenesulfonate SDBS:lg / L ratio
[0032] Example mixing, mechanical stirring, prepared nano-Al 2 o 3 Modified micro-arc oxidation electrolyte;
[0033] Step 3. Use the stainless steel plate of the electrolytic cell as the cathode, and the Mg-Zn-Ca-Sm-Be alloy as the anode, use the micro-arc oxidation electrolyte prepared in the above steps, and then use the pulse power supply as the power supply, and apply The voltage of 300V, and under the condition of voltage of 300V, temperature lower than 50℃ and stirring, the oxidation reaction was carried out for 5 minutes to obtain dense Al-containing 2 o 3 Micro-arc oxidation layer;

Abstract
The invention discloses an improved dual-use hand-held searchlight comprising a searchlight tube. A mounting seat is mounted at one end of the searchlight tube. A clamping groove is formed in the outer wall of one side of the mounting seat. The interior of the clamping groove is rotationally connected with a connecting plate through a rotating shaft, and mounting grooves are formed in the two sides of the clamping groove correspondingly. First springs and clamping blocks are mounted inside the mounting grooves. The improved dual-use hand-held searchlight is provided with a pushing rod, the connecting plate, the clamping groove, a pushing block, the clamping blocks, a second spring and a rotating shaft, when the using mode of the searchlight is changed, the pushing rod at one end of the connecting plate is pressed, the pushing rod pushes the pushing block to move, the pushing block pushes the clamping blocks to slide towards the two sides of the clamping groove in the moving process ofthe pushing block, meanwhile, the second spring is compressed, when the clamping blocks are completely pushed out of the connecting plate, the connecting plate is rotated, the connecting plate rotatesto drive a handle to rotate simultaneously until the handle and the searchlight tube are in a perpendicular state, at this time, the connecting plate is pushed downwards, and when one end of the connecting plate makes contact with the conductive end of a relay, the searchlight can be changed into the use state of a table lamp.
Description
technical field [0001] The invention belongs to the technical field of searchlights, in particular to an improved dual-purpose portable searchlight. Background technique [0002] A searchlight is a device with a powerful light source and a concave mirror that can concentrate and project the light in a specific direction. It is used for long-distance lighting and search purposes. Angle (generally less than 2 degrees) to obtain greater light intensity, in order to facilitate the use of the family, there are dual-purpose lamps that combine table lamps and searchlights in the market. [0003] But the existing dual-purpose searchlight in the market is not easy to carry out the transformation of desk lamp and searchlight, and the positioning structure of desk lamp is not stable enough. Contents of the invention [0004] The object of the present invention is to provide an improved dual-purpose portable searchlight to solve the existing problems of inconvenient conversion of des...
