DETAILED DESCRIPTION

[0031] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0032] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring that the present invention must be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] The specific implementation of the utility model provides a stacking logistics device for exhaust front pipes, which is composed of a plurality of device bodies stacked and combined. The device body is made of expanded polystyrene (EPS) in one piece. EPS is a light polymer, which is made of polystyrene resin with a foaming agent added, and heated to soften it, generating gas to form a rigid closed-cell foam plastic with low water absorption, good heat preservation, light weight and high mechanical strength. The device body has a top surface 1 and a bottom surface 2 of the body. The top surface 1 of the body is concave inward to form a plurality of cavities for accommodating exhaust front pipes 3, and each cavity can accommodate an exhaust front pipe 3 laterally. The logistics device of the utility model can accommodate multiple exhaust front pipes 3 at a time and provide good protection by stacking and combining, which overcomes the technical problems of low storage and transportation efficiency and easy damage of the exhaust front pipe 3 in the prior art to a certain extent.

[0034] like Figure 6The figure shows a schematic diagram of the structure of the exhaust front pipe in the embodiment of the utility model. The exhaust front pipe 3 is composed of a curved tubular first pressure differential pipe 31 and a second pressure differential pipe 32. The mounting clamp 33 is sleeved at the junction of the first pressure differential pipe 31 and the second pressure differential pipe 32. As can be seen from the figure, the mounting clamp 33 is irregular in shape and tilted outward, which is easily damaged by pressure. The end of the first pressure differential pipe 31 tilts inward, and the end of the second pressure differential pipe 32 tilts outward. The ends of the first pressure differential pipe 31 and the second pressure differential pipe 32 have sealing requirements. If the ends are deformed by pressure, it may cause the sealing to decrease after being connected to the engine, thereby affecting its technical performance.

[0035] like Figures 1 to 5 The figures are respectively the top perspective view, the upper view, the bottom perspective view, the lower view and the front view of the device body in the embodiment of the utility model. The logistics device of the utility model specially adopts corresponding technical measures for the above characteristics of the exhaust front pipe 3.

[0036] In view of the characteristics that the mounting clamp 33 is irregular in shape and tilted outward, firstly, the present embodiment adopts a storage posture in which the exhaust front pipe 3 is placed horizontally and the end of the first pressure difference tube 31 is facing downward, in order to avoid the outward-tilted mounting clamp 33 from contacting the cavity surface and preventing it from being deformed due to pressure. Secondly, the cavity of the main body top surface 1 is designed as a first cavity 121 and a second cavity 122 and is alternately distributed in the horizontal direction. The exhaust front pipe 3 accommodated in the first cavity 121 is deflected 180 degrees in the horizontal direction compared to the exhaust front pipe 3 accommodated in the second cavity 122, so as to avoid conflicts between the mounting clamps 33 of adjacent exhaust front pipes 3, thereby providing more cavities in the limited horizontal space of the main body top surface 1 to increase the number of exhaust front pipes 3 accommodated. Specifically, Figure 7 and Figure 8 As shown, there are respectively a top stereoscopic view and a top view of the device body accommodating the exhaust front pipe in the embodiment of the utility model, which can clearly show that the two adjacent exhaust front pipes 3 are placed in opposite directions, so the mounting clamps 33 do not conflict with each other, which significantly increases the number of exhaust front pipes 3 that can be accommodated.

[0037] In order to solve the problem that the compression deformation of the ends of the first differential pressure tube 31 and the second differential pressure tube 32 may lead to a decrease in sealing performance, the first assembly groove 13 and the second assembly groove 14 are formed by being recessed inward from the top surface 1 of the main body at both ends of the cavity. Among them, the first assembly groove 13 accommodates the end of the first differential pressure tube 31 in a vacuum, and the second assembly groove 14 accommodates the end of the second differential pressure tube 32 in a vacuum, that is, the ends of the first differential pressure tube 31 and the second differential pressure tube 32 are prevented from contacting with the device body, which can effectively avoid the problem of compression deformation. Since the end of the first differential pressure tube 31 is tilted inward, the first assembly groove 13 is deeper than the second assembly groove 14.

[0038] In order to solve the problem of limiting the position of the exhaust front pipe 3 when it is accommodated in the cavity, firstly, the cavity contour is adapted to the projection contour of the exhaust front pipe 3 in the accommodation posture, and the side wall of the cavity plays a role of clamping the first pressure difference tube 31 and the second pressure difference tube 32. Secondly, a clamp assembly groove 16 is provided in the cavity, which is formed by being recessed inward from the cavity surface or / and the top surface 1 of the main body. The clamp assembly groove 16 is adapted to the bottom surface shape of the mounting clamp 33 in the accommodation posture, and the lower half of the mounting clamp 33 is clamped by the clamp assembly groove 16. Thirdly, the top surface 1 of the main body is also recessed inward to form a clamp receiving groove 17 connected to the clamp assembly groove 16. Since each exhaust front pipe 3 is provided with two mounting clamps 33, each cavity is correspondingly provided with two clamp receiving grooves 17, and the clamp receiving groove 17 provides a receiving space for the upper half of the mounting clamp 33. Since the present layer of the device body can effectively limit the exhaust front pipe 3 accommodated therein in the lateral direction, the bottom surface 2 of the upper layer of the device body can actually limit the exhaust front pipe 3 in the present layer of the device body in the longitudinal direction, thereby preventing the exhaust front pipe 3 from shaking randomly and effectively reducing the chance of damage.

[0039] In order to prevent the exhaust front pipe 3 from being damaged due to bumps and collisions during storage and transportation, in addition to the device body being made of EPS foam material, the cavity surface is adapted to the bottom surface shape of the exhaust front pipe 3 in the storage posture to increase the contact area and ensure balanced force. In addition, a shock absorbing bump 15 is provided on the cavity surface to form an outward protrusion. When a longitudinal bump or collision occurs, the shock absorbing bump 15 collapses and deforms longitudinally, thereby providing a shock absorbing space for the exhaust front pipe 3.

[0040] In order to improve the stability of stacking multiple appliance bodies, the top surface 1 of the body is provided with a limiting column 11 formed by protruding outward, and the bottom surface 2 of the body is recessed inward to form a limiting groove 21 adapted to the limiting column 11. When multiple appliance bodies are stacked, the limiting column 11 of the lower layer of the appliance body is just embedded in the limiting groove 21 of the upper layer of the appliance body, thereby realizing the lateral limitation between adjacent appliance bodies. The bottom surface 2 of the body is recessed inward to form a material reduction groove 22, which plays a role in saving materials and reducing weight. In this embodiment, the limiting groove 21 is integrated with the material reduction groove 22 and is located at its edge, which is conducive to reducing the design difficulty and improving the yield rate.

[0041] In order to improve the support strength of stacking multiple tool bodies, the limiting groove 21 of the bottom surface 2 of the tool body is formed with a supporting crossbeam 23 which is the same height as the bottom surface 2 of the tool body and is continuously distributed, so as to improve the structural strength of the tool body itself. In addition, a support platform 18 which is the same height as the top surface 1 of the tool body is formed between the clamp groove 17 corresponding to the first cavity 121 and the clamp groove 17 corresponding to the adjacent second cavity 122. Figure 2Taking the figure shown as an example, the second cavity 122 on the far left corresponds to two clamp grooves 17, and the adjacent first cavity 121 also corresponds to two clamp grooves 17, and a support platform 18 is formed between the clamp groove 17 on the right side of the second cavity 122 and the clamp groove 17 on the left side of the first cavity 121. When multiple tool bodies are stacked, the support beam 23 of the upper tool body, which is at the same height as the bottom surface 2 of the tool body, is just supported on the support platform 18 of the lower tool body, which is at the same height as the top surface 1 of the tool body, thereby forming an effective support in the central part of the tool body to prevent the central part from collapsing.

[0042] When multiple appliance bodies are stacked, in order to facilitate operators to take out one or more layers of the appliance bodies, the embodiment of the utility model also adopts a hand-lifting groove design. The specific technical measures are: the top surface 1 and / or the bottom surface 2 of the body are recessed inward to form a first hand-lifting groove 24 connected to the side of the appliance body. The operator can easily lift the appliance body of the current layer through the first hand-lifting groove 24 of the bottom surface 2 of the body, and can also easily lift the upper layer of the appliance body through the first hand-lifting groove 24 of the top surface 1 of the body. Another solution can also be adopted, that is, Fig. 9 As shown, it is a three-dimensional view of the top surface of the tool body in the second embodiment of the utility model. The side surface of the tool body is recessed inward to form a second hand-lifting groove 25 which is not connected to the top surface 1 of the tool body. The operator can also easily lift the tool body of this layer through the second hand-lifting groove 25 on the side surface of the tool body.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
