Description

Technical Field

[0001] The utility model relates to the technical field of blister trays, in particular to a blister tray structure which can prevent a lower tray from being lifted up. 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] After the blister trays are produced, they are stacked for easy transportation, thereby reducing the space occupied and facilitating transportation. However, the existing blister trays are easily over-fitted due to their own gravity after being stacked in multiple layers due to their own materials, resulting in negative pressure inside the blister trays, which cause them to be stuck together. When the blister trays are needed, it is difficult to take them out, and it also affects the normal use of the blister trays. Utility Model Content

[0005] To achieve the above purpose, the utility model provides the following technical solution: a blister tray structure for preventing the lower tray from being lifted up, comprising a placement tray and a connecting shell fixed on both sides of the surface thereof, and also comprising:

[0006] A support block fixed to the bottom of the placement plate, wherein both sides of the placement plate surface are provided with fixing grooves, the bottom of the placement plate is provided with an installation groove, and the top of the inner cavity of the installation groove is fixedly connected with a connecting rope;

[0007] A counterweight block is fixed to the other end of the connecting rope, a blocking plate is fixedly connected to the lower part of the inner cavity of the installation groove, and connecting grooves are opened on both sides of the installation groove.

[0008] Preferably, the number of the support blocks is four and they are distributed at four corners of the bottom of the placement plate, and the support blocks are cylindrical in design.

[0009] Preferably, the surface of the counterweight block is slidably connected to the inner wall of the mounting groove, and the height of the counterweight block is smaller than the height of the inner cavity of the mounting groove.

[0010] Preferably, there are several blocking plates, and the blocking plates are made of rubber material.

[0011] Preferably, the height of the inner cavity of the connecting groove is greater than the diameter of the connecting rope, and the connecting rope is made of a flexible material.

[0012] Preferably, the height of the counterweight block is smaller than the height of the support block, and the counterweight block is used in conjunction with the support block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model can prevent the blister tray from being over-fitted when stacking through the function of the supporting block, and prevent the negative pressure from being formed inside the placement tray with the cooperation of the fixing groove, so that the blister tray will not be connected together when the user takes it. At the same time, with the cooperation of the connecting rope and the counterweight block, when taking the upper blister tray, the counterweight block can increase the weight of the lower blister tray, thereby reducing the situation that the upper blister tray carries the lower blister tray when moving, and solves the problem that the lower blister tray is easily carried when the upper blister tray is taken.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4As shown, a blister tray structure for preventing the lower tray from being lifted up comprises a placing tray 1, the placing tray 1 is used to receive articles, so as to facilitate the staff to take the articles, both sides of the surface of the placing tray 1 are fixedly connected with connecting shells 2, the connecting shells 2 can provide an effective force point when the staff takes the placing tray 1, so that it is more convenient and more labor-saving for the staff to take the placing tray 1, the bottom of the placing tray 1 is fixedly connected with supporting blocks 3, the number of supporting blocks 3 is four, and they are distributed at the four corners of the bottom of the placing tray 1, the supporting blocks 3 are cylindrical in design, and the placing tray 1 can be supported by the supporting blocks 3 to make it more stable, and when the tray is stacked, the upper and lower trays can be blocked to make the surface of the upper tray The surface will not excessively contact with the inner cavity of the lower pallet, avoiding excessive contact between the upper and lower pallets and getting stuck together due to the weight of the pallet itself when stacking, so as to facilitate the staff to take the pallet, and fixing grooves 4 are provided on both sides of the surface of the placement plate 1, and the number of fixing grooves 4 is several. Under this effect, when the pallet is stacked, air can enter the inner cavity of the lower pallet, avoiding the situation that the inner cavity of the lower pallet is squeezed by the upper pallet when stacking and the inner cavity forms a negative pressure, further improving the convenience of taking the pallet, and the bottom of the placement plate 1 is provided with an installation groove 5, and the top of the inner cavity of the installation groove 5 is fixedly connected with a connecting rope 6, and the other end of the connecting rope 6 is fixedly connected with a counterweight block 7. Under this effect, when the pallet is stacked, the counterweight block 7 can be used to The lower tray can be pressed down, and when the upper tray is taken, the counterweight block 7 can still squeeze the lower tray when the upper tray moves, so as to lift the weight of the lower tray, so that the lower tray will not move when the upper tray is taken. The surface of the counterweight block 7 is slidably connected to the inner wall of the mounting groove 5, and the height of the counterweight block 7 is less than the height of the inner cavity of the mounting groove 5. Under this effect, when stacking is not needed, the counterweight block 7 can be moved to the inside of the mounting groove 5 for storage, so as to avoid the counterweight block 7 affecting the normal use of the tray. A blocking plate 8 is fixedly connected to the lower part of the inner cavity of the mounting groove 5. The number of blocking plates 8 is several, and the blocking plate 8 is designed with rubber material. Under this effect, after the counterweight block 7 is stored, the counterweight block 7 can be moved under the action of the blocking plate 8. The balancing weight 7 is blocked to prevent it from moving randomly after entering the installation slot 5, which effectively improves the stability of the balancing weight 7 and prevents it from easily leaving the installation slot 5 and affecting the normal use of the tray. Both sides of the installation slot 5 are provided with connecting slots 9. The height of the inner cavity of the connecting slot 9 is greater than the diameter of the connecting rope 6. The connecting rope 6 is made of a flexible material. Under this action, the connecting rope 6 can be moved out of the installation slot 5 from the inside of the connecting slot 9 to prevent the placement plate 1 from being squeezed by the connecting rope 6 when being placed, which causes an unstable situation. The stability of the tray when being placed is effectively improved. The height of the balancing weight 7 is less than the height of the supporting block 3. The balancing weight 7 is used in conjunction with the supporting block 3. Under this action, the supporting block 3 can support the placement plate 1.The counterweight block 7 will not support the placement tray 1, so as to avoid the counterweight block 7 supporting the placement tray 1 and causing the support block 3 to be suspended, thereby affecting the stability of the tray.

[0022] Working principle: First, when stacking the pallet, the staff stacks the pallets one by one, and under the action of the fixed groove 4, it can be ensured that there will be no negative pressure inside each pallet, and under the action of the support block 3, each pallet will not have excessive contact to form a jamming situation. When taking the pallet for use, the staff directly moves the placement plate 1 through the connecting shell 2, and under the action of the counterweight block 7, the placement plate 1 below is pressed down to increase the weight of the lower pallet, so that when the staff takes the upper pallet, the lower pallet will not move with it. When the pallet needs to be used normally after taking it, the staff moves the counterweight block 7 to the inside of the installation groove 5, and limits the counterweight block 7 under the action of the blocking plate 8.
