Description

Technical Field

[0001] The utility model relates to the technical field of river demarcation, in particular to an easily fixed blister tray. Background Art

[0002] Blister trays are also called plastic inner trays. They use the blister process to make plastic sheets into plastic with specific grooves. The products are placed in the grooves to protect and beautify the products. There are also transport-type pallet packaging. Pallets are mostly used for convenience.

[0003] Most existing blister trays are flat structures, which makes it difficult to stack blister trays vertically when in use. Therefore, the blister trays need to be placed flat on the same horizontal plane when in use, which occupies a large plane space and reduces the utilization rate of the space. There is room for improvement.

[0004] Therefore, we propose an easy-to-fix blister tray to solve the above problems. Utility Model Content

A gear 7 is rotatably installed between them, and the gear 7 is symmetrically distributed about the rack 5 and meshingly connected with the rack 5. Brackets 8 are symmetrically fixed on the front and rear side walls of the gear 7, and a locking plate 9 is installed on the end of the bracket 8 away from the gear 7. When the two blister tray bodies 1 are stacked up and down, the positioning cylinder 4 of the upper blister tray under the action of gravity squeezes the rack 5 of the blister tray below, which can drive the rack 5 to move downward and drive the gear 7 to rotate, thereby driving the bracket 8 to rotate, so that the locking plate 9 of the lower blister tray can be buckled on the outer periphery of the positioning cylinder 4 of the upper blister tray, thereby improving the stacking stability of the upper and lower blister trays.

[0023] See also Figure 3 In order to improve the stability of the rack 5 in the extension and retraction inside the positioning cylinder 4, a movable groove 41 matching the rack 5 is provided inside the positioning cylinder 4, and the inner diameter of the movable groove 41 is 0.2-0.5mm larger than the outer diameter of the rack 5, thereby facilitating the extension and retraction movement of the rack 5 inside the movable groove 41 and reducing the shaking of the rack 5 inside the movable groove 41.

[0024] See also Figure 3In order to facilitate the separation of the two blister trays, the rack 5 can be reset, a spring 12 is installed on the inner bottom of the movable groove 41, the bottom end of the spring 12 is fixed to the inner bottom of the positioning cylinder 4, and the top end of the spring 12 is fixed to the rack 5, so that when the rack 5 retracts into the inside of the positioning cylinder 4, the spring 12 will be squeezed to shorten. When the pressure of the positioning cylinder 4 is lost above the rack 5, the rack 5 can rebound and reset under the elastic force of the spring 12, thereby causing the locking plate 9 to rotate and release the positioning cylinder 4.

[0025] See also Figure 2-3 In order to further improve the stability of the self-locking structure when locked, the bottom of the positioning cylinder 4 is connected to an end block 10, and the outer diameter of the end block 10 is larger than the outer diameter of the positioning cylinder 4, and the top of the rack 5 is connected to an end block 2 11, and the outer diameter of the end block 2 11 is larger than the outer diameter of the rack 5.
