Description

Technical Field

[0001] This utility model relates to the field of blister tray technology, specifically a blister tray structure that prevents the lower tray from being lifted up. Background Technology

[0002] Blister trays, also known as plastic inner trays, are made by forming a plastic sheet into a specific groove using a blister forming process. Products are placed in the groove to protect and enhance their appearance. There are also transport-type trays. The most common use of trays is for convenience.

[0003] A search revealed a structure for preventing a lower blister tray from being lifted by a lower tray, as disclosed in publication number CN 222876522 U. This structure includes a placement tray and connecting shells fixed to both sides of its surface. It also includes a support block fixed to the bottom of the placement tray. The placement tray has fixing grooves on both sides of its surface and an installation groove on its bottom. This invention, through the support block, prevents the blister trays from becoming overly compact when stacked. The fixing grooves prevent negative pressure from forming inside the placement tray, thus preventing the blister trays from sticking together when the user picks them up. Furthermore, the combination of the connecting rope and the counterweight increases the weight of the lower blister tray when the upper tray is picked up, reducing the likelihood of the lower tray being lifted by the upper tray during movement. This solves the problem of the lower blister tray being easily lifted when the upper tray is picked up.

[0004] However, the above-mentioned trays still have some shortcomings in use. They are not very adaptable to placing items of different sizes inside the tray, and it is difficult to flexibly adjust the internal space according to actual needs, making them inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a blister tray structure that prevents the lower tray from being lifted up, thus solving the problems of poor adaptability to placing items of different sizes inside the tray, difficulty in flexibly adjusting the internal space according to actual needs, and inconvenience in use.

[0006] This utility model provides the following technical solution: a blister tray structure to prevent the lower tray from being lifted up, including a tray body, a partition fixedly connected between the inner two side walls of the tray body, mounting boxes fixedly connected to both sides of the partition and the surfaces of the inner two side walls of the tray body, a slot opened on the upper surface and side of each mounting box, a sliding rod fixedly connected between the inner two side walls of each mounting box, a plurality of sliding sleeves slidably sleeved on the surface of each sliding rod, and a baffle fixedly connected between two corresponding sliding sleeves; Positioning rods are fixedly connected to the four corners of the lower surface of the pallet body, and positioning grooves matching the positioning rods are opened at the four corners of the upper surface of the pallet body. The length of the positioning rods is greater than the depth of the positioning grooves.

[0007] Preferred technical solution 1: Each of the sliding sleeves has a movable groove on its upper surface, and a locking rod is slidably fitted inside each of the movable grooves. Each sliding rod has a row of locking grooves that match the locking rod on its surface, and a first spring is fitted at the upper end of each locking rod.

[0008] Preferred technical solution 2: Each of the clamping rods has a pull plate fixedly connected to its top end, and two magnets are fixedly connected to the lower surface of each pull plate. Each sliding sleeve is made of iron.

[0009] Preferred technical solution 3: The lower surface of the tray body is provided with two rows of through holes, and a connecting rod is slidably sleeved inside each of the two rows of through holes. The bottom end of each of the two rows of connecting rods is fixedly connected to a top plate, and a second spring is fixedly connected between the top end of each connecting rod and the inner top wall of the corresponding through hole.

[0010] Preferred technical solution four: The inner bottom wall of the tray body and the surface of the multiple baffles are all provided with rubber pads.

[0011] Preferred technical solution five: The surface of each first spring and each second spring is coated with an anti-rust coating.

[0012] Compared with the prior art, this utility model provides a blister tray structure to prevent the lower tray from being lifted up, which has the following beneficial effects: When the staff stacks the trays one by one, the positioning rod and positioning groove can ensure that there is no negative pressure or excessive contact inside each tray to form a jam. At the same time, when the trays are stacked, the upper tray will be squeezed by gravity, which will cause the top plate to rise and squeeze the second spring. When the upper tray is removed, the second spring returns to its original shape and generates a downward elastic force, which separates the tray body from the lower tray and prevents the lower tray from being lifted up. When different items need to be placed inside the tray body, the locking lever can be released by pulling the pull plate upward to disengage it from the slot. Then, the sliding sleeve can be slid to move the baffle, thereby adjusting the space between multiple baffles. This makes it easy to place items of different sizes and offers high flexibility. This tray effectively prevents the lower tray from being lifted during use, and the space between multiple baffles can be adjusted according to actual needs, making it suitable for placing items of different sizes and easy to use.

[0015] Please see Figure 1-4 , Example 1: A blister tray structure to prevent the lower tray from being lifted up includes a tray body. A partition is fixedly connected between the two inner side walls of the tray body. Mounting boxes are fixedly connected to both sides of the partition and the surfaces of the two inner side walls of the tray body. Each mounting box has a slot on its upper surface and side. A sliding rod is fixedly connected between the two inner side walls of each mounting box. Multiple sliding sleeves are slidably fitted onto the surface of each sliding rod. A baffle is fixedly connected between two corresponding sliding sleeves. Positioning rods are fixedly connected to the four corners of the lower surface of the pallet body, and positioning grooves matching the positioning rods are opened at the four corners of the upper surface of the pallet body. The length of the positioning rods is greater than the depth of the positioning grooves.

[0016] Example 2: The difference between this example and Example 1 is that each of the sliding sleeves has a movable groove on its upper surface, a locking rod is slidably fitted inside each movable groove, a row of locking grooves matching the locking rod is opened on the surface of each sliding rod, and a first spring is fitted at the upper end of each locking rod.

[0017] Example 3: The difference between this example and Example 1 is that each of the card rods is fixedly connected to a pull plate at its top, and two magnets are fixedly connected to the lower surface of each pull plate. Each sliding sleeve is made of iron.

[0018] Example 4: The difference between this example and Example 1 is that the lower surface of the tray body has two rows of through holes, and a connecting rod is slidably fitted inside each of the two rows of through holes. The bottom end of each of the two rows of connecting rods is fixedly connected to a top plate, and a second spring is fixedly connected between the top end of each connecting rod and the inner top wall of the corresponding through hole.

[0019] Example 5: The difference between this example and Example 1 is that rubber pads are provided on the inner bottom wall of the tray body and the surfaces of the multiple baffles.

[0021] In summary, this blister tray structure, which prevents the lower tray from being lifted, allows workers to stack the trays one by one. Under the action of the positioning rod 8 and the positioning groove 9, it can be ensured that there is no negative pressure or excessive contact inside each tray, thus preventing jamming. At the same time, when the tray bodies 1 are stacked, the upper tray will be squeezed by gravity, causing the top plate 18 to drive the connecting rod 17 to rise and squeeze the second spring 4. When the upper tray is removed, the second spring 4 returns to its original shape and generates a downward elastic force, separating the tray body 1 from the lower tray and preventing the lower tray from being lifted. When different items need to be placed inside the tray body 1, the locking of the sliding sleeve 6 can be released by pulling the pull plate 14 upward to disengage the locking rod 11 from the slot 12. Then the sliding sleeve 6 can be slid to move the baffle 7, thereby adjusting the space between multiple baffles 7, which is convenient for placing items of different sizes and is highly flexible. This tray effectively prevents the lower tray from being lifted during use, and the space between the multiple baffles 7 can be adjusted according to actual needs, making it suitable for placing items of different sizes and easy to use.
