[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a testing device for chrome-plated plastic products, including a base plate 1, a placement platform 2 fixedly connected to the top of the base plate 1, the placement platform 2 including a bottom column, a lifting sleeve 3 slidably connected to the outside of the column, a plurality of transmission rods 4 rotatably connected to the outside of the lifting sleeve 3, a plurality of sliding grooves 6 adapted to the positions of the transmission rods 4 being opened inside the placement platform 2, a sliding seat 5 slidably connected to the inside of the sliding grooves 6, the top of the transmission rod 4 being rotatably connected to the corresponding sliding seat 5, a limiting sleeve 7 fixedly connected to the bottom of the sliding seat 5, an outer rotating sleeve 8 sleeved inside the limiting sleeve 7, and inner rotating sleeves 9 slidably connected to both ends inside the outer rotating sleeve 8, a cylinder fixedly connected to the top of the base plate 1, the output end of which is fixedly connected to the lifting sleeve 3, the number of sliding seats 5 is four, which are distributed in a ring on the inside of the placement platform 2, the number of outer rotating sleeves 8 and inner rotating sleeves 9 are four each, which form a ring structure and are staggered.

[0025] The chrome-plated plastic product to be tested is placed on the placement platform 2. The cylinder is started, pushing the lifting sleeve 3 to rise. Through the transmission rod 4, the slide 5 moves towards the product in the slide groove 6 to the appropriate position. At the same time, the outer rotating sleeve 8 is moved through the limiting sleeve 7.

[0026] Please see Figures 1-4 Springs 10 are fixedly connected to both ends of the inner side of the outer rotating sleeve 8. The two springs 10 are fixedly connected to the inner rotating sleeves 9 at both ends. A rack 11 is fixedly connected to the top of the outer rotating sleeve 8. A first gear 12 and a rotating shaft 13 are rotatably connected to the bottom of the slide 5. The rack 11 meshes with the corresponding first gear 12. A transmission seat 15 and a second gear 14 are fixedly connected to the outer side of the rotating shaft 13. The first gear 12 and the second gear 14 mesh at a right angle. A transmission belt 16 is sleeved on the inner side of the transmission seat 15. The top of the slide 5 rotates... A rotating rod 17 is connected, and a transmission seat 15 is connected to the rotating rod 17 via a transmission belt 16. A clamp 18 is fixedly connected to the outside of the rotating rod 17. The rotating rod 17 includes a driven seat in the middle of the outer side. One end of the transmission belt 16 away from the transmission seat 15 passes through the slide 5 and is sleeved on the inside of the driven seat. An outer fixed seat 19 is fixedly connected to the top of the base plate 1. A compression detection mechanism 20 is fixedly connected to the top of the outer fixed seat 19. A compression head is fixedly connected to the bottom of the compression detection mechanism 20. The compression head is located above the center of the placement platform 2.

[0027] The inner rotating sleeve 9 slides into the outer rotating sleeve 8 and stretches the spring 10. Its rebound force ensures the stability of the inner rotating sleeve 9 and the outer rotating sleeve 8 in a ring structure. Rotating the ring structure drives the four first gears 12 to rotate through the rack 11, and drives the rotating shaft 13 and the transmission seat 15 to rotate through the second gear 14. In turn, the rotating rod 17 is driven to rotate through the transmission belt 16, causing the clamp 18 to rotate toward the product. The clamp plate connected to its end presses and fixes the product. The extrusion detection mechanism 20 is activated, the extrusion head descends and extrudes and detects the product, and transmits the data to the display screen fixed at the top of the outer fixed seat 19.

[0028] The up-and-down movement of the lifting sleeve 3 controls the tilt angle of the transmission rod 4, thereby driving the slide block 5 to move synchronously and smoothly within the slide groove 6. This ensures that the four slide blocks 5 maintain a consistent moving speed and distance, allowing for flexible adjustment based on the actual size of the product. This achieves broad adaptability to products of different sizes. The rotatable clamp 18, driven by the transmission belt 16, can quickly and accurately clamp the product, preventing any displacement during the inspection process and improving the applicability and stability of the device.

[0029] The staggered interlocking design of the outer rotating sleeve 8 and the inner rotating sleeve 9, combined with the stability and rebound force provided by the spring 10, allows the ring structure to not only adjust its size with the limiting sleeve 7, but also ensure its structural stability. The meshing of the rack 11 with the first gear 12 can drive the four first gears 12 to rotate synchronously. In conjunction with the second gear 14 and the rotating shaft 13, it can drive the rotation of the transmission seat 15. It is then connected to the rotating rod 17 through the transmission belt 16, realizing the conversion of the rotational motion of the first gear 12 into the rotational motion of the rotating rod 17, thereby driving the synchronous rotation of the four clamps 18. This series of mechanical transmission processes is not only efficient and precise, but also greatly reduces the working steps and improves the detection efficiency.

[0030] The working principle and usage process of this utility model are as follows: The plastic chrome-plated product to be tested is placed on the placement platform 2. The cylinder is started, pushing the lifting sleeve 3 to rise. Through the transmission rod 4, the sliding seat 5 moves towards the product in the sliding groove 6 to a suitable position. At the same time, the limiting sleeve 7 drives the outer rotating sleeve 8 to move, and the inner rotating sleeve 9 slides into the outer rotating sleeve 8, stretching the spring 10. Its rebound force ensures the stability of the inner rotating sleeve 9 and the outer rotating sleeve 8 in a ring structure. Rotating the ring structure drives the four first gears 12 to rotate through the rack 11, and drives the rotating shaft 13 and the transmission seat 15 to rotate through the second gear 14. Then, the rotating rod 17 is driven to rotate through the transmission belt 16, causing the clamp 18 to rotate towards the product. The clamp plate connected to its end is used to press and fix the product. The extrusion detection mechanism 20 is started, the extrusion head descends and extrudes and detects the product, and transmits the data to the display screen fixed at the top of the outer fixed seat 19.

[0031] The above-mentioned extrusion detection mechanism 20 is the prior art disclosed in this utility model, and will not be described in detail here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
