[0003] During the use of the color screen of the existing laser rangefinder, due to the lack of a targeted heat dissipation structure for the color screen, a large amount of heat is generated during the normal operation of the color screen, causing the temperature of the color screen itself to rise rapidly, even exceeding the working temperature that the color screen itself can withstand, resulting in abnormal or non-working phenomena of the color screen, thus affecting the normal use of the laser rangefinder. Therefore, a heat dissipation structure for a color screen bonded to an aluminum part is proposed to solve the above problems. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution:

[0006] A heat dissipation structure for a color screen bonded to an aluminum part is provided. The color screen is arranged inside the laser rangefinder, and further includes an aluminum part. The aluminum part is fixedly connected to the inner side of the shell of the laser rangefinder. The color screen is bonded to the inner side of the aluminum part, and a limiting member is arranged on the aluminum part.

[0007] Further, the limiting member includes a sleeve fixedly connected to the outer side of the aluminum part at one end. A limiting rod is slidably connected to the inner side of the sleeve, and one end of the limiting rod penetrates and extends to the inner side of the aluminum part. A blocking block is fixedly connected to the outer side of the limiting rod. A spring is fixedly connected between the blocking block and the aluminum part. The end of the limiting rod away from the aluminum part penetrates the sleeve, and the end of the limiting rod penetrating the aluminum part is inclined. A supporting block is fixedly connected to the inner bottom wall of the aluminum part, and the color screen is placed on the supporting block.

[0008] Further, the aluminum part is an aluminum frame, the supporting block is a rubber block, and the supporting block is L-shaped.

[0009] Further, both sides and the back of the color screen are bonded to the inner side wall of the aluminum part, and heat dissipation holes are formed in the aluminum part at the back of the color screen.

[0010] Further, one end of the limiting rod away from the aluminum part is L-shaped. A groove is formed in the inner side wall of the sleeve and is located outside the L end of the limiting rod. A rubber bump is fixedly connected to the inner side of the groove.
