DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 The utility model embodiment is a double-layer composite blister box for packaging precision parts, which includes an outer envelope 1, a cover plate 2, a partition device 3 and an inner envelope 6. The lower surface of the outer envelope 1 is fixedly connected with a buffer pad 4, the front surface of the outer envelope 1 is fixedly connected with a lower positioning ring 5, the front surface of the cover plate 2 is fixedly connected with an upper positioning ring 8, the inner surface of the upper positioning ring 8 is rotatably connected with a bolt 9, the side surface of the bolt 9 is threadedly connected with the lower positioning ring 5, the lower end of the bolt 9 is threadedly connected with a nut 10, the inner surface of the outer envelope 1 is fixedly connected with the inner envelope 6, the front and rear inner walls of the inner envelope 6 are fixedly connected with a limited track 7, a slide rail 14 is arranged inside the outer envelope 1, and the inner surface of the slide rail 14 is slidably connected with the cover plate 2.

[0024] The partition device 3 includes a longitudinal partition plate 11, a transverse partition plate 12, a slider 15, a ball 16, a sleeve 17, a slide column 18 and a spring 19. The inner surface of the limiting track 7 is slidably connected to the longitudinal partition plate 11, and the left and right sides of the longitudinal partition plate 11 are slidably connected to the transverse partition plate 12. The side of the transverse partition plate 12 away from the inner envelope 6 is fixedly connected to the slider 15, the outer surface of the ball 16 is rotatably connected to the sleeve 17, the inner surface of the sleeve 17 is slidably connected to the slide column 18, one end of the spring 19 is fixedly connected to the sleeve 17, and the end of the spring 19 away from the sleeve 17 is fixedly connected to the transverse partition plate 12. The left and right sides of the longitudinal partition plate 11 are provided with a slide groove 13, the inner surface of the slide groove 13 is slidably connected to the slider 15, the side surface of the sleeve 17 is slidably connected to the transverse partition plate 12, the slide column 18 passes through the inside of the spring 19, and the left and right inner walls of the inner envelope 6 are provided with limiting grooves 20, which are adapted to the ball 16.

[0025] Working principle: when in use, pull out the cover plate 2, and according to the size of the parts, bend the transverse partition plate 12 to make the slider 15 slide along the direction of the slide groove 13. At this time, the ball 16 rolls along the inner wall of the inner envelope 6, and the spring 19 is compressed. The ball 16 passes through the limiting groove 20 in turn. When it reaches the required position, the ball 16 stops rolling and falls into the corresponding limiting groove 20 at this time, thereby realizing the relative fixation of the transverse partition plate 12 and the longitudinal partition plate 11. At this time, the space formed by the inner envelope 6, the longitudinal partition plate 11, and the transverse partition plate 12 can just adapt to the size of the parts. Then insert the bolt 9 and tighten the nut 10 to realize the limitation of the outer envelope 1 and the cover plate 2. When replacing parts, you only need to bend the transverse partition plate 12 again to adjust the space size, which can effectively maximize the utilization of the space inside the blister box, improve the space utilization rate of the blister box, and can also change the size of each partition, so that parts of different sizes can be placed, which improves the adaptability of the blister box and has higher functionality.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
