[0028] See also Figures 1 to 5 , shown is a protective cover for a laser rangefinder 13 in an embodiment of the utility model, characterized in that it includes a shell 10 and a heat-insulating chamber located in the shell 10, the heat-insulating chamber is surrounded by a blocking component, a first accommodating chamber 11 for placing electronic components is formed in the shell 10, a second accommodating chamber 12 for placing the laser rangefinder 13 is formed in the heat-insulating chamber, a first sliding plate 20 is slidably provided on the side of the shell 10, the first sliding plate 20 passes through the heat-insulating chamber and abuts against the side of the laser rangefinder 13, a second sliding plate 30 is slidably provided on the top surface of the shell 10, the second sliding plate 30 passes through The first sliding plate 20 and the second sliding plate 30 abut against the top surface of the laser rangefinder 13 through the heat insulation chamber, and the second accommodating chamber 12 is divided into a heating space for accommodating the tail of the laser rangefinder 13 and an emitting space for accommodating the front of the laser rangefinder 13. The heating space is connected to the first accommodating chamber 11 through a first through hole 64. A first temperature sensor 51 and a heating module 52 are provided in the first accommodating chamber 11. A second temperature sensor 65 is provided in the heating space. Both the first temperature sensor 51 and the second temperature sensor 65 are electrically connected to the heating module 52.

[0029] It can be understood that by providing a heat-insulating chamber in the housing 10 and placing the laser rangefinder 13 in the heat-insulating chamber, the storage space of the laser rangefinder 13 can be effectively compressed, and the temperature in the heat-insulating chamber can be reduced more slowly. At the same time, the first sliding plate 20 and the second sliding plate 30 are abutted against the laser rangefinder 13, so that the tail and the front of the laser rangefinder 13 are separated. The tail of the laser rangefinder 13 will emit heat due to the presence of electronic components. This heat will be enclosed in the heating space, so that the laser rangefinder 13 can always maintain a high temperature. Then, a first temperature sensor 51 and a heating module 52 are provided in the first accommodating chamber 11, and a heating module 52 is provided in the second accommodating chamber 11. A second temperature sensor 65 is arranged in the nanocavity 12. When the temperature of the electronic component in the first accommodating cavity 11 is low, it is sensed by the first temperature sensor 51, and a signal is sent to the heating module to dissipate heat, so as to heat the temperature in the first accommodating cavity 11. At the same time, the heat can be transferred to the heating space through the first through hole 64. When a second temperature sensor 65 is arranged in the heating space, it is sensed by the second temperature sensor 65, and a signal is sent to the heating module to dissipate heat. Similarly, the temperature in the first accommodating cavity 11 is heated, and at the same time, the heat is transferred to the heating space through the first through hole 64. This design can take into account the most suitable temperature environment for the electronic components and the laser rangefinder 13.

[0030] Furthermore, the blocking assembly includes a first side wall 62 and a second side wall 63 respectively connected to two inner side walls of the housing 10 , and an upper wall 61 located above the first side wall 62 and the second side wall 63 .

[0031] It can be understood that the heat insulation chamber is located in a corner of the first accommodating cavity 11 , and the heat insulation chamber is only composed of the first side wall 62 , the second side wall 63 , and the upper wall 61 .

[0032] The side wall of the housing 10 is provided with a first strip groove 25 for the first sliding plate 20 to slide, the first sliding plate 20 is provided with a first slider 23, the first strip groove 25 is provided with a first slide groove 26 cooperating with the first slider 23, and a damping structure is provided between the first slider 23 and the first slide groove 26.

[0033] It can be understood that after the shell 10 is put on the electronic components and the laser rangefinder 13, the first sliding plate 20 is pressed to make it abut against the laser rangefinder 13. The cooperation between the first slider 23 and the first slide groove 26 makes the movement of the first sliding plate 20 smoother. At the same time, a damping structure is set between the first slider 23 and the first slide groove 26, so that the first sliding plate 20 will not be easily displaced during use.

[0034] Furthermore, the top wall of the shell 10 is provided with a second strip groove 32 for the second sliding plate 30 to slide, the upper wall 61 is provided with a third strip groove 15 for the second sliding plate 30 to slide, the second sliding plate 30 is provided with a second slider 31, the second strip groove and the third strip groove 15 are respectively provided with a second slide groove 33 and a third slide groove 16 that cooperate with the second slider 31, and a damping structure is provided between the second slider 31 and the second slide groove 33.

[0035] It can be understood that by pressing the second sliding plate 30 so that it passes through the upper wall 61 and abuts against the laser rangefinder 13, the cooperation between the second slider 31 and the second slide groove 33 and the third slide groove 16 makes the movement of the second sliding plate 30 smoother. At the same time, a damping structure is set between the second slider 31 and the second slide groove 33, so that the second sliding plate 30 will not shift easily during use.

[0036] Furthermore, the first sliding plate 20 includes a motherboard 21 and a sub-plate 22 that is telescopic inside the motherboard 21, a telescopic rod 66 is provided at the top end of the sub-plate 22, and the telescopic rod 66 slides inside the side wall of the shell 10, and a fourth sliding groove 24 is also provided at the top end of the sub-plate 22 for the telescopic rod 66 to slide, and a damping structure is provided between the telescopic rod 66 and the inside of the side wall of the shell 10; a second through hole 14 for the power cord 50 to pass through, and a light-transmitting hole 40 for the laser beam of the laser rangefinder 13 to pass through are provided on the side wall of the shell 10, and the light-transmitting hole 40 is located at the emission space.

[0037] As can be understood, the first sliding plate 20 is first pressed to make it abut against the laser rangefinder 13. At this time, the sub-plate 22 is extended out of the template. While the first sliding plate 20 slides, the telescopic rod 66 also slides in the fourth sliding groove 24. Then the second sliding plate 30 is pressed to make it abut against the laser rangefinder 13. The second sliding plate 30 will squeeze the sub-plate 22 to make it enter the mother plate 21. At the same time, the telescopic rod 66 also moves downward inside the side wall of the shell 10. This design structure allows the second sliding plate 30, the sub-plate 22, and the mother plate 21 to be almost completely separated from the heating space and the emission space, so that the heat of the heating space can be better maintained and the heat of the heating space is prevented from being emitted from the light-transmitting hole 40. The telescopic rod 66 will also block the first strip groove 25 at the side wall of the shell 10. A damping structure is set between the telescopic rod 66 and the inside of the side wall of the shell 10, so that the telescopic rod 66 can pull the sub-plate 22 to prevent the sub-plate 22 from falling downward due to the action of gravity.

[0038] Furthermore, a power module 53 for supplying power to the laser rangefinder 13 is also disposed inside the first accommodating cavity 11 .

[0039] Furthermore, the protective cover of the laser rangefinder 13 also includes a bottom plate located below the housing 10, and the bottom plate is provided with a mounting hole.

[0040] In summary, the laser rangefinder protective cover in the above embodiment of the utility model can effectively compress the storage space of the laser rangefinder by setting a heat-insulating chamber in the shell and placing the laser rangefinder in the heat-insulating chamber, so that the temperature in the heat-insulating chamber can be reduced more slowly. At the same time, the first sliding plate and the second sliding plate are abutted on the laser rangefinder, so that the tail and the front of the laser rangefinder are separated. The tail of the laser rangefinder will emit heat due to the presence of electronic components. This heat will be enclosed in the heating space, so that the laser rangefinder can always maintain a high temperature. Then, a first temperature sensor and a first temperature sensor are set in the first accommodating cavity. A heating module and a second temperature sensor are arranged in the second accommodating cavity. When the temperature of the electronic component in the first accommodating cavity is low, it is sensed by the first temperature sensor, and a signal is sent to the heating module to dissipate heat, so as to heat the temperature in the first accommodating cavity. At the same time, the heat can be transferred to the heating space through the first through hole. When a second temperature sensor is arranged in the heating space, it is sensed by the second temperature sensor, and a signal is sent to the heating module to dissipate heat. Similarly, the temperature in the first accommodating cavity is heated, and at the same time, the heat is transferred to the heating space through the first through hole. This design can take into account the most suitable temperature environment for electronic components and laser rangefinders.
