[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment: A detection device for detecting the heat dissipation performance of a projector, as Figures 1-6 shown, comprising a projector 1, a fixing frame 2, a rotating frame 3, a display screen 4, a sliding rod 5, a fixing block 6, a spring 7, a placement rack 8, a first thermosensitive sensor 9, a connecting rod 10, a connecting frame 11, a second thermosensitive sensor 12, a fixing frame 13, a fixing rod 14, a strong adhesive 15, a fixing pin 16, a pull ring 17, a mounting plate 18 and a warning light 19. A heat dissipation port 101 is provided on the front side of the projector 1, and the heat generated during the operation of the projector 1 is discharged through the heat dissipation port 101. The fixing frame 2 is clamped to the rear side of the projector 1, and the rotating frame 3 is rotatably connected to the fixing frame 2. The display screen 4 is mounted on the rotating frame 3. The sliding rod 5 is slidably connected to the fixing frame 2. The bottom end of the sliding rod 5 is connected to the fixing block 6, and a spring 7 is connected between the fixing block 6 and the fixing frame 2. The placement rack 8 is placed diagonally on the projector 1. The placement rack 8 is in an inverted U shape. The first thermosensitive sensor 9 is installed inside the rear placement rack 8. Since the first thermosensitive sensor is a device that can sense temperature changes and convert such changes into measurable electrical signal outputs, the connecting rod 10 is connected to the front placement rack 8. The bottom end of the connecting rod 10 is connected to the connecting frame 11. The second thermosensitive sensor 12 is installed inside the connecting frame 11. The fixing frames 13 are symmetrically mounted on the left and right sides of the placement rack 8. The fixing rod 14 is clamped inside the fixing frame 13. A fixing hole 1401 is provided on the fixing rod 14. The strong adhesive 15 is installed at the bottom of the fixing rod 14. The fixing pin 16 is inserted into the fixing hole 1401, and the fixing pin 16 penetrates through the fixing frame 13 to fix the fixing rod 14. The pull ring 17 is connected to the outer side of the fixing pin 16. The mounting plate 18 is mounted on the display screen 4, and several warning lights 19 are mounted on the mounting plate 18 to play a warning role. The number of warning lights 19 is not less than three.
[0022] When the device needs to be used and heat dissipation detection is required during the use of the projector 1, the user first pulls the sliding rod 5 upward. The sliding rod 5 drives the fixed block 6 to move, and the spring 7 is compressed. Then, the fixing frame 2 is placed at the rear side of the projector 1 for clamping. After the clamping of the fixing frame 2 is completed, the user releases the sliding rod 5, and the spring 7 resets, moving the fixed block 6 and the sliding rod 5 downward. The sliding rod 5 moves and contacts the projector 1 to complete the installation of the fixing frame 2. Then, a placement rack 8 is placed above the bulb of the projector 1. After the first placement rack 8 is placed, the connecting rod 10 is placed in the fixing frame 13. At the same time, the strong adhesive 15 at the bottom of the connecting rod 10 contacts the projector 1. Next, the user passes the fixing pin 16 through the fixing frame 13 and clamps it into the fixing hole 1401 to complete the installation of the first thermal sensor 9. The user then places the second placement rack 8 at a position on the projector 1 close to the heat dissipation port 101. At the same time, the connecting rod 10 on the second placement rack 8 and the connecting frame 11 can be aligned with the heat dissipation port 101 of the projector 1. Then, the above operation is repeated to fix the second placement frame, and the installation of the second thermal sensor 12 can be completed. During the use of the projector 1, the first thermal sensor 9 can detect the temperature at the position above the bulb of the projector 1 and upload it to the display screen 4. The second thermal sensor 12 can detect the temperature at the heat dissipation port 101 of the projector 1 and upload it to the display screen 4. The user can view the information on the display screen 4 to judge the heat dissipation performance of the projector 1. When the temperature of the first thermal sensor 9 is relatively high, the first warning light 19 on the mounting plate 18 lights up. When the temperature of the second thermal sensor 12 is relatively high, the second warning light 19 on the mounting plate 18 lights up. When the temperatures of both the first thermal sensor 9 and the second thermal sensor 12 are relatively high, the third warning light 19 on the mounting plate 18 lights up, thus facilitating the observation of the heat dissipation performance effect of the projector 1.
[0023] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
