Description

Technical Field

[0001] The utility model relates to the technical field of blow molding barrels, in particular to a high-density blow molding barrel with an impact-resistant and shock-absorbing structure. Background Art

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. Blow molding technology began to be used to produce low-density polyethylene bottles during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some production has been computer-controlled. However, at present, blow molding barrels are all small plastics. When a large amount of material needs to be loaded, more blow molding barrels are needed to load the material, which wastes blow molding barrels. In addition, traditional blow molding barrels will break when they collide, and will cause a large footprint.

[0003] The utility model with publication number CN212501463U discloses a high-density polyethylene blow-molded barrel with a low-temperature impact-resistant structure, including a sliding seat, the inner walls opposite to the inner cavity of the sliding seat are symmetrically fixed with sliding grooves, the inner cavity of the sliding seat is slidably sleeved with a sliding rod, the lower surface of the sliding rod is symmetrically fixedly connected with a slide plate, the bottom of the sliding rod is fixedly connected to the bottom of the inner cavity of the sliding seat by a second spring, the surface of the output end of the second spring is fixedly connected to the surface of the moving rod by a first spring, and the slide plate is slidably sleeved in the inner cavity of the sliding groove.

[0004] As shown in the above-mentioned utility model, the existing blow molding barrel can buffer the force generated by the impact through the buffer device outside the shell to eliminate the impact force during a collision. In this way, the buffer device is fixed on the shell of the blow molding barrel. When impacted, even if there is a buffer mechanism to buffer, the blow molding barrel itself will still be affected by the impact, causing its shell to be easily damaged. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] See Figure 1-3 , the utility model provides the following two technical solutions:

[0025] The first embodiment: a high-density blow-molded barrel with an impact-resistant and shock-absorbing structure, comprising:

[0026] A blow molding barrel body 1, a base 11 is fixed to the bottom of the blow molding barrel body 1;

[0027] The protective component 2 is arranged adjacent to the four outer sides of the blow molding barrel body 1. The two protective components 2 are connected in a close fit to protect the blow molding barrel body 1. The protective component 2 includes a bottom plate 21 arranged on the upper surface of the base 11. The bottom plate 21 is fixed to the base 11 by a plurality of bolts distributed at equal intervals. Support columns 22 are fixed at both ends of the bottom plate 21. The lower ends of the support columns 22 are fixedly connected to the bottom plate 21 through a reinforcing plate, thereby improving the connection strength between the support columns 22 and the bottom plate 21. The two support columns 22 are fixed by a plurality of connecting plates 23 distributed vertically at equal intervals. Telescopic rods 24 are arranged at both ends of the connecting plates 23. The movable ends of the telescopic rods 24 are fixed with The impact-resistant plate 25 has a plurality of air bags 26 which are distributed vertically at equal intervals bonded to the outer side of the impact-resistant plate 25. The setting of the air bags 26 plays a role of preliminary impact resistance and buffering. A plurality of connecting columns 27 which are distributed vertically at equal intervals are fixed on one side of the support column 22, and a plurality of connecting grooves 28 which are distributed vertically at equal intervals are opened on one side of the support column 22. The connecting columns 27 and the connecting grooves 28 are staggered, and the connection between two adjacent support columns 22 is inserted into the corresponding connecting grooves 28. The adjacent two protective components 2 are connected by the connecting columns 27 and the connecting grooves 28, so that the four protective components 2 form a frame structure, which improves the overall strength and plays a protective role for the blow-molded barrel therein;

[0028] The buffer component 3 is arranged inside the protection component 2 and is used for buffering and shock absorbing the blow molding barrel body 1.

[0029] The second embodiment is mainly different from the first embodiment in that the buffer component 3 includes a spring 31, which is arranged in the middle of the outer side of the connecting plate 23, and the middle of the spring 31 is in contact with the middle of the anti-impact plate 25. The spring 31 deforms when subjected to force, thereby playing a buffering role. Both ends of the spring 31 are fixed with movable plates 32, and one side of the movable plate 32 is fixed with a dovetail slider 33. Both sides of the outer side of the connecting plate 23 are provided with dovetail grooves 34, and a damping layer is bonded to the inner wall of the dovetail groove 34. The dovetail slider 33 is located in the dovetail groove 34 and in contact with the damping layer. When the spring leaf 31 is subjected to force, it drives the movable plate 32 to move, so that the dovetail slider 33 moves in the dovetail slot 34. The dovetail slider 33 cooperates with the damping layer to play a damping and shock absorption role. Fixed plates 35 are fixed to both ends of the outer side of the connecting plate 23. A through groove 36 is provided on the fixed plate 35. A connecting rod 37 is connected through the through groove 36. One end of the connecting rod 37 is fixedly connected to the movable plate 32. A spring 38 is sleeved on the outer side of the connecting rod 37. The spring 38 is located between the fixed plate 35 and the movable plate 32. When the movable plate 32 moves, the spring 38 is compressed, which plays a buffering role.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] During installation, first install the protection component 2 with the connecting column 27 and the connecting groove 28 at both ends on the base 11, then place the other two protection components 2 on the base 11, insert the connecting grooves 28 and connecting columns 27 on the inner sides thereof into the connecting columns 27 and connecting grooves 28 on the adjacent protection components 2, and then fix the other two protection components 2 on the base 11 with bolts;

[0032] When the protective component 2 is impacted by the outside, the airbag 26 is first deformed by the force, which plays a preliminary buffering role. Then the impact-resistant plate 25 is forced to move inward, driving the spring 31 to deform, which plays a secondary buffering role. The spring 31 drives the movable plate 32 to move when deformed, and the movable plate 32 drives the dovetail slider 33 to move in the dovetail slot 34. The dovetail slider 33 cooperates with the damping layer in the dovetail slot 34 to play a damping and shock-absorbing role. At the same time, the movable plate 32 drives the spring 38 to be compressed when moving, which plays a further buffering role, thereby improving the buffering effect of the device, and further protecting the blow molding barrel, thereby preventing the outer shell of the blow molding barrel body 1 from being damaged under impact force.
