DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 As shown, a sunglass frame fatigue resistance test device comprises a protective shell 1, a control mechanism 2 is movably installed on the upper surface of the protective shell 1 near the front side, a speaker 3 is fixedly connected to the upper surface of the protective shell 1 near the left front side, a first fixing clamp 4 is fixedly connected to the middle part of the upper surface of the protective shell 1 near the rear side, a power mechanism 5 is fixedly connected to the inner side of the protective shell 1 near the front side, and a testing mechanism 6 is rotatably connected to the inner side of the protective shell 1 near the rear side.

[0027] It should be noted that the control mechanism 2 is used to control the operation of the electrical components in the device, and the speaker 3 is used to generate sound to remind after the test is completed.

[0028] like Figure 2 , Figure 3 As shown, the power mechanism 5 includes a motor 51, the upper surface of the motor 51 is fixedly connected to the inner upper surface of the protective shell 1 near the front side, the output end of the motor 51 is fixedly connected to a turntable 52, the lower surface of the turntable 52 is rotatably connected to a connecting rod 53 near the edge, the end of the connecting rod 53 near the first fixing clamp 4 is rotatably connected to a rack 54, and the lower side of the rack 54 is slidably connected to the inner lower surface of the protective shell 1.

[0029] It should be noted that the motor 51 drives the turntable 52 to rotate. When the turntable 52 rotates, the connecting rod 53 pushes or pulls the rack 54, causing the rack 54 to reciprocate in the front-rear direction.

[0030] like Figure 2 , Figure 3As shown, a spur gear 55 is rotatably connected to the middle of the inner lower surface of the protective shell 1, and the lower side of the spur gear 55 is meshingly connected to the upper side of the rack 54. A transmission rod 56 is rotatably connected to the inner left and right sides of the protective shell 1 near the rear side, and a first sprocket 57 is fixedly connected to the middle of the outer wall of the transmission rod 56 and the front axis of the spur gear 55, and the side of the first sprocket 57 is meshingly connected to the first chain 58.

[0031] It should be noted that when the rack 54 moves, it drives the spur gear 55 to rotate. When the spur gear 55 rotates, it drives the first sprocket 57 located on the front side to rotate. Relying on the first chain 58, the two first sprockets 57 rotate synchronously in the same direction, causing the transmission rod 56 to rotate. Since the rack 54 reciprocates in the front and back directions, the transmission rod 56 rotates back and forth in the clockwise and counterclockwise directions.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the testing mechanism 6 includes a handwheel 61, the middle left part of the handwheel 61 is connected to the rear middle part of the right part of the protective shell 1, and the inner left and right sides of the handwheel 61 near the rear side are rotatably connected with two screw rods 62 symmetrically distributed front and back, the right end of the screw rod 62 located on the front side is fixedly connected to the left side axis of the handwheel 61, and the outer wall of the screw rod 62 is threadedly connected with two movable seats symmetrically distributed left and right.

[0033] It should be noted that rotating the handwheel 61 drives the screw rod 62 located on the front side to rotate. The screw rod 62 is a bidirectional screw rod having two threads in opposite directions. The two movable seats 63 are threadedly connected to the threads in different directions, so that when the screw rod 62 rotates, the two movable seats 63 move in opposite directions in the left and right directions.

[0034] like Figure 4 As shown, the outer walls of the two screw rods 62 are fixedly connected to the positions near the left ends thereof with second sprockets 64 , and the outer sides of the second sprockets 64 are meshingly connected to the second chains 65 .

[0035] It should be noted that when the screw rod 62 on the front side rotates, it drives the second sprocket 64 on the front side to rotate, and the two second sprockets 64 rotate synchronously in the same direction by relying on the second chain 65, and then the two screw rods 62 rotate synchronously in the same direction, so that the front and rear sides of the moving seat 63 are subjected to balanced force.

[0036] like Figure 5As shown, the upper surfaces of the two movable seats 63 are fixedly connected to a fixing frame 67 near the middle, the inner upper surfaces of the two fixing frames 67 are rotatably connected to the first bevel gear 66, and the upper surfaces of the two movable seats 63 are rotatably connected to the second bevel gear 68 at the boss on the side close to each other, the upper side of the second bevel gear 68 is meshed and connected with the side of the first bevel gear 66 close to each other, and the inner side of the second bevel gear 68 is movably sleeved on the outer wall of the transmission rod 56.

[0037] It should be noted that when the transmission rod 56 rotates, the two second bevel gears 68 are driven to rotate synchronously in the same direction. When the second bevel gear 68 rotates, the first bevel gear 66 is driven to rotate. Since the two second bevel gears 68 are located on the side where the two first bevel gears 66 are close to each other, the two first bevel gears 66 rotate synchronously in the opposite direction.

[0038] like Figure 5 As shown, the upper axes of the two first bevel gears 66 are fixedly connected to rotating rods 69 through round rods, and the rotating rods 69 are located on the upper side of the protective shell 1. The upper surfaces of the two rotating rods 69 near the front ends are fixedly connected to second fixing clamps 610.

[0039] It should be noted that the second fixing clip 610 is used to fix the temple of the glasses, and the first bevel gear 66 is just below the rotating position of the temple of the glasses. The first bevel gear 66 drives the rotating rod 69 to rotate, causing the rotating rod 69 to drive the second fixing clip 610 to rotate, so that the second fixing clip 610 drives the temple of the glasses to rotate.

[0040] like Figure 1 As shown, four rectangularly distributed supporting feet are fixedly connected to the lower surface of the protective housing 1 near the four corners.

[0041] It should be noted that rubber pads are provided on the lower sides of the support legs to reduce the vibrations generated when the internal components of the device are in operation.

[0042] The working principle of the utility model is as follows: first, the hand wheel 61 is rotated to drive the screw rod 62 located at the front side to rotate. The screw rod 62 is a bidirectional screw rod, which contains two threads in opposite directions. The two moving seats 63 are respectively threadedly connected with threads in different directions, so that when the screw rod 62 rotates, the two moving seats 63 perform reverse movements in the left and right directions. When the screw rod 62 located at the front side rotates, it drives the second sprocket wheel 64 located at the front side to rotate. The two second sprocket wheels 64 are synchronously rotated in the same direction by relying on the second chain 65, and then the two screw rods 62 are synchronously rotated in the same direction, so that the front and rear sides of the moving seat 63 are balanced in force. By rotating the screw rod 62, the two second fixing clamps 610 perform lateral reverse movements, so that the spacing between the two second fixing clamps 610 is adjusted, so that when facing When glasses of different sizes are used, the spacing between the two second fixing clamps 610 can be adjusted as needed to meet the needs of different situations, thereby improving the applicability of the device. Finally, the motor 51 drives the turntable 52 to rotate. When the turntable 52 rotates, the connecting rod 53 pushes or pulls the rack 54, causing the rack 54 to reciprocate in the front and rear directions. When the rack 54 moves, it drives the spur gear 55 to rotate. When the spur gear 55 rotates, it drives the first sprocket 57 located on the front side to rotate. Relying on the first chain 58, the two first sprockets 57 rotate synchronously in the same direction, causing the transmission rod 56 to rotate. Since the rack 54 reciprocates in the front and rear directions, the transmission rod 56 reciprocates clockwise and counterclockwise. When the transmission rod 56 rotates, it drives the two second bevel gears 68 to rotate synchronously in the same direction. When the second bevel gear 68 rotates, it drives the first bevel gear 66 to rotate. Since the two second bevel gears 68 are located on the side where the two first bevel gears 66 are close to each other, the two first bevel gears 66 rotate synchronously in opposite directions. The second fixing clamp 610 is used to fix the temples of the glasses. The first bevel gear 66 is just below the rotating position of the temples of the glasses. The first bevel gear 66 drives the rotating rod 69 to rotate, causing the rotating rod 69 to drive the second fixing clamp 610 to rotate, so that the second fixing clamp 610 drives the temples of the glasses to rotate. The motor 51 drives the turntable 52 to rotate, causing the rack 54 to reciprocate forward and backward, causing the transmission rod 56 to reciprocate, and then causing the two rotating rods 69 to reciprocate at a certain angle, thereby performing a fatigue resistance test on the temples of the glasses. The operation is convenient, the structure is simple, and it is convenient and fast.
