[0002] Flat nozzles are essential structural connection components for aerospace piping systems. During production and delivery, they require long-distance transportation. Due to inadequate protective measures during transportation, users often discover numerous surface bruises during acceptance inspection. To address these bruises, individual rubber sleeves or pearl cotton foam are used for packaging or transportation. However, this significantly increases the packaging workload, and at the assembly site, the workload of disassembling the packaged parts is significant. Furthermore, a high volume of foreign or redundant material is introduced, compromising on-site 6S management requirements. Utility Model Content

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0020] Figure 1 The schematic diagram shows the overall structure of the quick-release anti-collision transport sheath. Figure 2The schematic diagram shows the cross-sectional structure of the quick-release anti-collision transport sheath. Figure 3 The cross-sectional structure of the tie rod is shown schematically. Figure 4 The schematic diagram shows the cross-sectional structure of the casing, a quick-release anti-collision transport sheath such as Figure 1 and Figure 2 As shown, it includes a hollow sleeve 1 and a pull rod 2 that can reciprocate in the sleeve 1. Figure 4 As shown in FIG, a pair of oblique holes 3 are provided along the radial direction on the sleeve 1, and barbs 4 are provided along the radial direction on the outer edge of the pull rod 2 (as shown in FIG. Figure 3 As shown in the figure, the width of the inclined hole 3 is not less than the radial width, and the spacing between adjacent inclined holes 3 is not less than the height of the flat nozzle. With the above structure, when the flat nozzle needs to be transported, the pull rod 2 is pulled to the left, and the barbs 4 on the pull rod 2 can be retracted into the sleeve. After the flat nozzle is installed from the right end, the pull rod 2 is returned to its original position, and the barbs 4 on the pull rod 2 extend from the inclined hole 3, completing the positioning of the flat nozzle.

[0021] The following is a detailed description of the quick-release anti-collision transport sheath.

[0022] Example 1

[0023] A pull ring 5 is fixedly provided at one end of the aforementioned pull rod 2 for pulling the pull rod 2, and a limit step 7 is fixedly provided on the other end. A return spring 6 is also sleeved on the pull rod 2, with one end of the return spring 6 in contact with the limit step 7 and the other end in contact with the sleeve 1, or the two ends of the return spring 6 are respectively fixed to the limit step 7 and the sleeve 1. Due to the provided return spring 6, after the pull rod 2 is first pulled to the left, the barb 4 retracts into the sleeve, completing the loading process of the flat nozzle. After the pull ring 5 is subsequently released, the pull rod 2 will return to its original position under the action of the return spring 6, and the barb 4 will re-extend from the inclined hole 3, completing the limit of the bottle nozzle tube. An elastic circlip 8 is also provided on the pull rod 2. The elastic circlip 8 is arranged close to the pull ring 5, and the elastic circlip 8 can contact the side of the sleeve 1 close to the pull ring 5. That is, after the pull rod 2 returns to its position, the elastic circlip 8 contacts the sleeve 1, which is used to prevent the pull rod 2 from moving too much to the right due to the elastic force of the return spring 6.

[0024] Example 2

[0025] On the basis of Example 1, a groove (not shown) for the barb 4 to be pressed into is provided on the pull rod 2 facing the barb 4, one end of the barb 4 is rotatably connected to the groove, and an elastic member (not shown) is added between the barb 4 and the groove. Through the provided groove and elastic member, the barb 4 can be received in the groove after entering the sleeve, and when the pull rod 2 is returned to its original position under the action of the return spring 6, the barb 4 can be ejected from the groove again and extended out of the inclined hole 3 by the elastic member provided between the barb 4 and the groove. However, in this process, it is still necessary to manually or mechanically pull the pull rod 2 to the specified position to ensure that the barb 4 will not extend from the inclined hole 3, which is not conducive to a single person completing the fixation of the flat pipe nozzle on the sleeve 1. Therefore, a fixing groove (not shown) can be opened on the side of the sleeve 1 facing the pull rod 2. The fixing groove is opened by rotating a certain angle based on the position of the inclined hole 3, so that it can accommodate the barb 4, and the force between the barb 4 and the fixing groove is used to complete the fixation of the pull rod 2 in the sleeve. At this time, the placement of the flat pipe nozzle can be completed directly, and the pull rod 2 can be restored to its original position to complete the limitation of the flat pipe nozzle. In this process, it is only necessary to pull the pull ring 5 until the barb 4 is retracted into the sleeve, rotate the pull rod 2 at a certain angle to fix the pull rod 2 and the sleeve with the barb 4, and then rotate the pull rod 2 at a certain angle to complete the return under the action of the return spring 6. The entire process can be completed by a single person.

[0026] It is worth noting that the barbs 4 involved in the aforementioned embodiments 1 and 2 are any one of sheet-like structures, rod-like structures and block-like structures, or a combination of multiple structures. The present invention does not limit this, and it only needs to be able to meet the relevant limiting and fixing functions.

[0027] By setting the barbs 4, the mutual contact, friction and bumps between the flat nozzle parts can be avoided, the bumps generated during the transportation of the flat nozzle can be solved, and the surface quality can be improved. To quickly put the parts into the turnover protective gear, you only need to pull the pull ring 5 hard to move the barb 4 pull rod 2 to the left a certain distance, so that the barbs 4 on the barb 4 pull rod 2 are retreated into the protective gear sleeve 1, and the flat nozzle can be easily and quickly put into the protective gear sleeve 1, loosen the pull ring 5, and the barbs 4 are extended, which can limit the axial displacement of the flat nozzle and prevent it from falling off; finally, you only need to pull the pull ring 5 hard to move the barb 4 pull rod 2 to the left a certain distance, so that the barbs 4 on the barb 4 pull rod 2 are retreated into the protective gear sleeve 1, and the flat nozzle can easily slide out of the pipe sleeve.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
