Description

Pearl cotton cushion

technical field

The utility model relates to a packaging material, in particular to a pearl cotton shock-absorbing pad.

Background technique

Pearl cotton is a kind of polyethylene foamed cotton, which has a non-crosslinked closed-cell structure and is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed, and poor in recovery. It has many advantages such as water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance.

And the existing pearl cotton shock absorbers are all flat. When supplying ceramic products and home appliances, when providing packaging protection for these heavier products, the pearl cotton shock absorbers are all designed thicker, so as to improve The effect of shock absorption and buffering, such a structure is extremely easy to waste materials, and the manufacturing cost is high, so there is no price competitive advantage in the market.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a pearl cotton shock-absorbing pad with effectively reduced material, ingenious structure and improved shock-absorbing effect.

In order to achieve the above purpose, the utility model provides the following technical solutions: a pearl cotton shock absorbing pad, including a backing plate, a plurality of prismatic holes arranged in sequence are arranged on the thickness surface of the backing plate, and The four hole walls of the shaped hole are respectively protruded with buffer blocks, and the two sides of the buffer block are respectively protruded with extruded strips arranged along the length direction of the buffer block, and the outer end surfaces of the extruded strips are arc-shaped. Shape, the buffer block at the upper position of the inner wall of the prismatic hole and the buffer block at the lower position of the inner wall of the prismatic hole are arranged at intervals and correspond to each other, and an exhaust groove is also provided at the bottom of the backing plate, the said The exhaust groove includes a transverse guide groove, a longitudinal guide groove and an intersection groove, and the transverse guide groove and the longitudinal guide groove communicate with the intersection groove respectively.

The transverse guide groove is arranged along the transverse direction of the backing plate, the longitudinal guide groove is arranged along the longitudinal direction of the backing plate, and the intersection groove is in the shape of a circular groove.

The buffer block is in the shape of a square, and the buffer block at the upper position of the inner wall of the prismatic hole and the buffer block at the lower position of the inner wall of the prismatic hole are set at an interval of 0.2 cm to 0.4 cm.

With this structure of the utility model, the prismatic holes provided on the backing plate not only reduce the weight of the whole backing plate, but also the buffer blocks on the wall of the prismatic hole correspond to the upper and lower intervals, so that the pads can contact each other when they are squeezed by weight. Buffering, and after the buffer block is squeezed and shrunk, a buffer structure that contacts and squeezes is formed between the extrusion blocks on both sides of the buffer block, which greatly improves the cushioning effect of the backing plate, and the exhaust groove under the backing plate can It effectively prevents the backing plate from being in contact with the bottom surface to prevent air discharge and drainage, prevents slipping, and can reduce the weight of the backing plate, thus achieving the technical effects of effectively reducing materials, ingenious structure and improving shock absorption effect.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

As shown in Figures 1-3, the present embodiment discloses a pearl cotton shock-absorbing pad, comprising a backing plate 1, a plurality of prismatic holes 2 arranged in sequence are arranged on the thickness surface of the backing plate 1, and The four hole walls of the hole 2 are respectively protruded with buffer blocks 3, and the two sides of the buffer block 3 are respectively protruded with extruded bars 4 arranged along the length direction of the buffer blocks 3, and the outer end surfaces of the extruded bars 4 are arc-shaped. The buffer block 31 of the upper position of the inner wall of the prismatic hole 2 and the buffer block 32 of the lower position of the inner wall of the prismatic hole 2 are arranged at intervals and correspond to each other, and the bottom of the backing plate 1 is also provided with an exhaust groove 5, and the exhaust groove 5 includes The transverse guide groove 51 , the longitudinal guide groove 52 and the intersection groove 53 , the transverse guide groove 51 and the longitudinal guide groove 52 communicate with the intersection groove 53 respectively. In this way, the technical effect of effectively reducing materials, ingenious structure and improving shock absorption effect is realized.

The transverse guide groove 51 is arranged along the transverse direction of the backing plate 1 , the longitudinal guide groove 52 is arranged along the longitudinal direction of the backing plate 1 , and the intersection groove 53 is in the shape of a circular groove. Such a design can make the exhaust groove 5 more convenient and reliable when the exhaust groove 5 is in contact with the bottom surface, effectively prevent the backing plate 1 from slipping in contact with the bottom surface, and reduce the weight of the backing plate 1 at the same time.

The buffer block 3 is in the shape of a square, and the buffer block 31 at the upper position of the inner wall of the prismatic hole 2 and the buffer block 32 at the lower position of the inner wall of the prismatic hole 2 are arranged at an interval of 0.2 cm to 0.4 cm. Such an arrangement can further improve the reliability and shock absorption effect of the buffer block 3 .

With this structure of the utility model, the prismatic hole 2 provided on the backing plate 1 not only reduces the weight of the whole backing plate 1, but also the buffer blocks 3 on the wall of the prismatic hole 2 correspond to each other at intervals up and down, so that the spacer is squeezed by the weight , they can be in contact with each other for buffering, and after the buffer block 3 is extruded and shrunk, a buffer structure in which mutual contact and extrusion is formed between the extruded blocks on both sides of the buffer block 3, greatly improves the buffering effect of the backing plate 1, and the pad The exhaust groove 5 below the plate 1 can effectively prevent the effect of exhaust and drainage when the backing plate 1 is in contact with the bottom surface to prevent slipping, and can reduce the weight of the backing plate 1, thus achieving effective material reduction, ingenious structure and improved The technical effect of the shock-absorbing effect.
